COMMUNITY HEALTH NURSING - I

UNIT 4: NUTRITION ASSESSMENT, NUTRITION EDUCATION & FOOD SAFETY

(As per INC Syllabus | Based on Park's Textbook of Preventive & Social Medicine)

SECTION A: NUTRITION - CONCEPTS & REVIEW

1. CONCEPTS OF NUTRITION

Definition of Nutrition: The science that deals with food and how the body uses it. Nutrition is a process by which the body takes in and uses food for growth, development, energy, and maintenance of life.

Types of Nutrition:

Type	Description
Adequate Nutrition	Intake meets the body's requirements
Optimal Nutrition	Best possible nutrition for health and performance
Under-nutrition	Intake below requirements (deficiency)
Over-nutrition	Excessive intake leading to obesity, toxicity
Malnutrition	Any condition resulting from inadequate OR excessive diet

Nutrients and Their Classification:

Category	Examples	Function
Macronutrients	Carbohydrates, Proteins, Fats	Energy, growth, repair
Micronutrients	Vitamins (A, B, C, D), Minerals (Fe, Ca, I)	Regulation, protection
Water	-	Transport, temp regulation
Roughage/Fibre	Cellulose	Bowel movement

Balanced Diet: A diet that provides all essential nutrients in adequate amounts to maintain health, growth, and activity. Based on age, sex, physiological state, and activity level.

2. MEAL PLANNING

Definition: The process of planning menus for a person or family to ensure adequate nutrition at minimum cost.

Aims of Meal Planning:

To meet nutritional requirements of the individual/family
To use available food resources economically
To prevent nutritional deficiency diseases
To satisfy appetite and provide satiety
To consider food preferences, culture, religion, and habits
To maintain health and prevent disease

Steps of Meal Planning:

Assess the nutritional needs (age, sex, physiological state, activity)
Identify available foods in the locality and their costs
Plan menus using food groups (cereals, pulses, vegetables, fruits, milk, fats)
Ensure variety, color, texture, and palatability
Check against Recommended Daily Allowances (RDA) by ICMR
Consider cooking methods to preserve nutrients
Evaluate and revise the plan

Diet Plan for Different Age Groups:

Age Group	Key Nutrient Focus	Special Considerations
Infants (0-1 yr)	Breast milk/formula, iron after 6 months	Exclusive breastfeeding for 6 months
Toddlers (1-3 yr)	Protein, Calcium, Iron, Vit A & D	Small frequent meals
Preschool (3-6 yr)	Balanced diet, micronutrients	Finger foods, variety
School age (6-12 yr)	Energy, protein, calcium for growth	School meal programs
Adolescents	Iron (girls), Calcium, Protein	Rapid growth phase
Pregnant women	Folic acid, Iron, Calcium, +300 kcal extra	Avoid alcohol, raw meat
Lactating mothers	+550 kcal extra, Calcium, Iron	Adequate fluid intake
Elderly	Low calorie, high fiber, Calcium, Vit D	Soft, easily digestible foods

ICMR RDA Highlights (key exam values):

Adult male (moderate work): 2,875 kcal/day
Adult female (moderate work): 2,225 kcal/day
Pregnancy: +300 kcal/day
Lactation: +550 kcal/day
Protein: 0.8-1 g/kg body weight/day for adults

3. NUTRITION ASSESSMENT

Definition: The systematic collection and interpretation of data to identify nutrition-related problems in individuals, families, and communities.

Methods - ABCD Method:

A - Anthropometric Assessment

Measurement of body dimensions and composition.

Indicator	Normal Values	Use
Weight-for-age	Reference WHO charts	Underweight detection
Height-for-age	Reference WHO charts	Stunting (chronic malnutrition)
Weight-for-height	-	Wasting (acute malnutrition)
Mid-Upper Arm Circumference (MUAC)	>13.5 cm (normal), 12.5-13.5 cm (at risk), <12.5 cm (SAM)	Quick field screening
BMI	18.5-24.9 (normal), <18.5 (underweight), >25 (overweight)	Adult nutritional status
Head circumference	33-35 cm at birth, 47 cm at 1 year	Brain growth
Skin fold thickness	Triceps, subscapular	Body fat estimation

B - Biochemical Assessment

Laboratory tests to detect subclinical deficiencies.

Deficiency	Test
Anaemia	Hemoglobin (<12 g/dL women, <13 g/dL men = anaemia)
Protein deficiency	Serum albumin (<3.5 g/dL = hypoalbuminemia)
Vitamin A deficiency	Serum retinol (<20 µg/dL)
Iodine deficiency	Urinary iodine excretion
Vitamin D	Serum 25-OH Vitamin D
Iron status	Serum ferritin, serum iron, TIBC

C - Clinical Assessment

Niacin (B3)	Pellagra - 3 Ds: Dermatitis, Diarrhoea, Dementia
Iodine	Goitre, cretinism
Iron	Pallor, koilonychia (spoon nails), fatigue
Protein-Energy	Kwashiorkor (edema, pot belly), Marasmus (wasting)
Zinc	Poor wound healing, growth retardation
Fluorosis	Dental/skeletal fluorosis (excess fluoride)

D - Dietary Assessment

Evaluation of food intake patterns.

Methods:

24-hour dietary recall - Subject recalls all food/drinks in past 24 hours; simple, quick, but relies on memory
Food frequency questionnaire (FFQ) - How often certain foods are consumed weekly/monthly
Weighed food record - Actual weighing of food for 3-7 days; most accurate but laborious
Diet history - Detailed past dietary habits; used for long-term assessment
Food balance sheets - National/community level assessment

At Community Level - Additional Methods:

Growth monitoring (weight charting in children)
Ecological surveys (food availability, soil quality)
Vital statistics (mortality, morbidity data)

4. PLANNING SUITABLE DIET FOR INDIVIDUALS AND FAMILIES

Factors to Consider:

Local availability of foods - Use seasonal, locally grown foods; reduce cost
Dietary habits - Cultural, religious food preferences (vegetarian, halal, etc.)
Economic status - Low-cost nutritious foods: millets, pulses, green leafy vegetables (GLV), eggs
Age and physiological state - Adjust for pregnancy, lactation, illness, old age
Food groups - Ensure representation from all groups daily

Food Groups (INC Guideline):

Group 1: Cereals, millets, pulses (energy and protein)
Group 2: Vegetables and fruits (vitamins, minerals, fiber)
Group 3: Milk and milk products (calcium, protein)
Group 4: Oils, fats, sugar (energy)
Group 5: Flesh foods (meat, fish, eggs) - protein, iron

Low-cost Nutritious Foods:

Millets (ragi, jowar, bajra) - iron, calcium
Green leafy vegetables - iron, folic acid, Vit A
Pulses (dal) - protein, iron
Eggs - complete protein
Groundnuts - protein, fat

5. GENERAL NUTRITIONAL ADVICE

Key points a nurse should give:

Eat from all food groups daily
Include green leafy vegetables at every meal
Consume adequate water (6-8 glasses/day)
Avoid excess salt, sugar, and saturated fats
Breastfeed exclusively for 6 months
Use iodized salt for all cooking
Expose to sunlight for Vitamin D
Avoid junk food and packaged foods
Supplement iron and folic acid during pregnancy
Maintain proper food hygiene and safe water

SECTION D: FOOD BORNE DISEASES AND FOOD SAFETY

1. FOOD BORNE DISEASES - DEFINITION & BURDEN

Definition (WHO): Food borne diseases are illnesses, usually either infectious or toxic in nature, caused by agents that enter the body through ingestion of food.

Burden:

WHO estimates 600 million people fall ill and 420,000 die each year from foodborne diseases
Children under 5 years bear 40% of the foodborne disease burden
Leading cause: Diarrheal diseases (most commonly due to contaminated food and water)
Developing countries most affected due to poor sanitation, inadequate food hygiene

Causes:

Biological: Bacteria, viruses, parasites, fungi
Chemical: Pesticides, heavy metals, food additives (aflatoxins)
Physical: Glass pieces, metal fragments

Classification of Food Borne Diseases:

Category	Examples
Food-borne infections	Typhoid, cholera, hepatitis A, salmonellosis, brucellosis
Food-borne intoxications (poisoning)	Botulism, staphylococcal toxin, aflatoxins
Food-borne toxic infections	Cl. perfringens, B. cereus
Chemical food poisoning	Organophosphate, arsenic, mercury, nitrates
Zoonotic food borne diseases	Brucellosis, anthrax, Q fever (from animals)

2. SIGNS & SYMPTOMS OF FOOD BORNE DISEASES

Common symptoms (gastroenteritis):

Nausea, vomiting
Diarrhoea (watery or bloody)
Abdominal cramps and pain
Fever (usually low grade)
Dehydration

Red flag signs requiring immediate referral:

High fever with rigors
Bloody diarrhoea
Signs of dehydration (sunken eyes, dry mouth, decreased urine output, poor skin turgor)
Neurological symptoms (double vision, difficulty swallowing - botulism!)
Jaundice (hepatitis A)
Shock, hypotension
Confusion/altered sensorium

3. TRANSMISSION OF FOOD BORNE PATHOGENS & TOXINS

Routes of Transmission:

Fecal-oral route - Contaminated food/water (most common)
Person-to-person - Infected food handlers
Animal-to-human (zoonotic) - Contaminated meat, milk, eggs
Environmental contamination - Soil (Cl. perfringens), water
Cross-contamination - Raw to cooked food during preparation

Vehicles of Transmission:

Water (cholera, typhoid)
Milk and dairy products (brucellosis, staphylococcal poisoning, salmonella)
Meat and poultry (salmonella, Cl. perfringens, E. coli O157:H7)
Eggs and egg products (salmonella)
Shellfish (hepatitis A, Vibrio species)
Canned foods (botulism)

Factors Favoring Food Borne Disease Outbreaks:

Improper temperature storage (bacteria multiply between 5-60°C = "danger zone")
Inadequate cooking
Poor personal hygiene of food handlers
Cross-contamination (raw vs cooked)
Unsafe water for washing

4. EARLY IDENTIFICATION, INITIAL MANAGEMENT, AND REFERRAL

Nurse's Role in Early Identification:

Detailed food history (what was eaten, when, how many people affected)
Epidemiological link (common meal, same food item consumed)
Onset and type of symptoms
Time between eating and onset (incubation period clues the causative agent)

Incubation Period as a Diagnostic Clue:

Onset After Eating	Likely Cause
1-6 hours	Staphylococcal toxin, chemical
6-24 hours	Salmonella, Cl. perfringens
24-72 hours	E. coli, Shigella, Yersinia
1-7 days	Typhoid, hepatitis A, Brucella
Neurological symptoms	Botulism

Initial Management (ORS and supportive care):

Assess hydration status - check skin turgor, eyes, mouth, urine output
Oral Rehydration Solution (ORS) for mild-moderate dehydration
IV fluids for severe dehydration or inability to tolerate oral intake
Antipyretics for fever
Anti-emetics if needed
Do NOT give antidiarrheal drugs routinely (can prolong illness)
Continue feeding (BRAT diet not required - normal diet as tolerated)
Collect stool sample before antibiotics if needed

Referral Criteria:

Children < 2 years with diarrhea and vomiting
Severe dehydration or shock
Bloody diarrhea with high fever
Neurological symptoms (botulism suspicion)
Suspected typhoid or hepatitis A
Outbreak involving multiple cases
Immunocompromised patients
No improvement in 48-72 hours

SECTION E: FOOD POISONING & FOOD INTOXICATION

FOOD POISONING

Definition: Food poisoning is an acute gastroenteritis caused by ingestion of food or drink contaminated with either living bacteria, their toxins, or inorganic chemical substances and poisons derived from plants and animals.

Characteristics (classical triad):

History of ingestion of a common food
Attack of many persons at the same time
Similarity of signs and symptoms in majority

TYPES OF FOOD POISONING

A. NON-BACTERIAL FOOD POISONING

Caused by chemicals - arsenic, mercury, lead, cadmium, fertilizers, pesticides, cadmium.

B. BACTERIAL FOOD POISONING

1. Salmonella Food Poisoning (Most Common Bacterial Type)

Agent: S. typhimurium, S. cholerae-suis, S. enteritidis
Source: Farm animals, poultry, eggs, contaminated meat, milk; also rats/mice
Incubation period: 12-24 hours (commonly)
Mechanism: Organisms multiply in intestine → acute enteritis + colitis
Symptoms: Sudden onset, chills, fever, nausea, vomiting, profuse watery diarrhoea (2-3 days)
Mortality: ~1%
Prevention: Proper cooking, refrigeration, avoid cross-contamination

2. Staphylococcal Food Poisoning

Agent: Enterotoxins of Staphylococcus aureus (coagulase-positive); heat-stable toxins (resist boiling for 30 min)
Source: Skin, nose, throat of food handlers; custards, salads, milk products
Incubation period: 1-8 hours (short because toxin is PREFORMED in food)
Mechanism: "Intradietic" toxins - preformed in food; toxin acts on intestine and CNS
Symptoms: Sudden violent nausea, vomiting, abdominal cramps, prostration; diarrhoea; low-grade fever or no fever; recovery in 24 hours
Exam Note: Very short IP because toxin is already in the food

3. Clostridium botulinum Food Poisoning (Botulism)

Agent: Cl. botulinum produces one of the most potent toxins known (neurotoxin type A, B, E most common in humans)
Source: Home-canned vegetables and meats (anaerobic, improperly preserved)
Incubation period: 12-36 hours (range 2 hours to 8 days)
Mechanism: Toxin absorbed from intestine → reaches CNS → blocks acetylcholine release at neuromuscular junction → flaccid paralysis
Symptoms: NEUROLOGICAL (NO fever, NO diarrhoea) - diplopia (double vision), dysarthria, dysphagia, descending flaccid paralysis; respiratory failure can cause death
Key feature: Descending symmetrical paralysis; patient remains conscious
Treatment: Antitoxin (50,000-100,000 units IV); ventilatory support; Guanidine hydrochloride
Prevention: Proper canning (autoclaving), not consuming home-canned food with bulging lids

4. Clostridium perfringens Food Poisoning

Agent: Cl. perfringens (welchii); spores survive cooking
Source: Cooked meat and poultry stored at room temperature
Incubation period: 6-24 hours (peak 10-14 hours)
Mechanism: Spores survive cooking; germinate during cooling; organisms multiply and produce toxins (alpha, theta toxins)
Symptoms: Diarrhoea, abdominal cramps; NO fever; little/no vomiting; short duration (1 day); no deaths
Prevention: Cook meat just before consumption; rapid and adequate cooling if stored

5. Bacillus cereus Food Poisoning

Agent: B. cereus (gram-positive spore-bearer, ubiquitous in soil)
Source: Rice dishes (fried/boiled rice left at room temp), cereals, spices
Two syndromes:
- Diarrhoeal syndrome (IP 6-15 hours) - watery diarrhoea, abdominal cramps (like Cl. perfringens)
- Emetic syndrome (IP 1-5 hours) - nausea and vomiting (like Staph. aureus) - associated with fried rice
Prevention: Refrigerate cooked rice, consume promptly

FOOD INTOXICATION

Definition: Illness caused by consumption of food containing preformed toxins produced by microorganisms (toxin ingested, NOT the organism).

Key distinction from food infection:

Food infection: ingestion of live organisms which then multiply in the body
Food intoxication: ingestion of preformed toxin in the food (e.g., botulism, staphylococcal)

Features of Food Intoxication:

Short incubation period (toxin already present)
No fever usually (except rare cases)
Symptoms predominantly GI (vomiting, diarrhoea) or neurological (botulism)
Not transmissible person-to-person

Preventive and Control Measures for Food Intoxication:

Proper food storage (refrigeration, <5°C)
Adequate cooking temperature (>70°C core temp)
No consumption of food in bulging/dented cans
Proper personal hygiene of food handlers
Avoid leaving food at room temperature for >2 hours
Safe water supply
Proper waste disposal
Health education of food handlers

5. PUBLIC HEALTH RESPONSE TO FOOD BORNE DISEASES

Steps in Outbreak Investigation (PHEIC Response):

Case finding and case definition - Identify all affected persons
Notify authorities - Report to CDMO, PHO, state health department
Epidemiological investigation:
- Attack rate calculation
- Spot map
- Epidemic curve (source-common point or propagated)
- Food specific attack rates to identify vehicle
Laboratory investigation:
- Collect stool/vomit/blood samples from cases
- Collect food samples from suspected source
- Culture and sensitivity
Control measures:
- Remove and destroy contaminated food
- Treat cases (ORS, antibiotics if indicated)
- Close contaminated food establishment if necessary
- Decontaminate premises
Prevention of further cases:
- Public health advisory
- Inspecting food handling practices
- Safe water supply
- Health education to community and food handlers
Reporting and documentation:
- Submit outbreak investigation report
- Notifiable disease (Food poisoning is notifiable under Epidemic Diseases Act, 1897)

Food Safety Legislation in India:

Food Safety and Standards Act (FSSA), 2006 - Main law governing food safety; replaced PFA Act 1954
FSSAI (Food Safety and Standards Authority of India) - Regulatory body under FSSA 2006
Prevention of Food Adulteration Act (PFA), 1954 - Now replaced by FSSA 2006
Essential Commodities Act, 1955 - Controls supply of essential food items

🚽 SEWAGE DISPOSAL SYSTEM

BSc Nursing 5th Sem | Community Health Nursing - I

Source: Park's Textbook of Preventive and Social Medicine

DEFINITION

Sewage: Wastewater from a community containing solid and liquid excreta from houses, streets, factories, and industries.

Sewage = 99.9% water + 0.1% solids (organic + inorganic)
Sullage = Wastewater WITHOUT human excreta (kitchen, bathroom waste)
Dry weather flow = Average sewage flowing in 24 hours through sewers

PUBLIC HEALTH IMPORTANCE OF EXCRETA DISPOSAL

Improper disposal causes:

Soil pollution
Water pollution
Food contamination
Fly breeding

Diseases caused: Typhoid, Cholera, Dysentery, Diarrhoea, Hepatitis A, Hookworm, Ascariasis

Route of transmission - "5 Fs":

Faeces → Fingers → Flies → Food → Fluid (water) → New Host

Sanitation Barrier = Breaking the disease cycle by segregating faeces through proper latrines/sewers

BOD - BIOCHEMICAL OXYGEN DEMAND ⭐

"Standard indicator of organic content of sewage"

BOD Level	Sewage Strength
100 mg/L	Weak sewage
300 mg/L or above	Strong sewage

Aim of treatment: Reduce BOD to acceptable levels before discharge
Effluent from treatment plant should not reduce dissolved oxygen of receiving water below 4 mg/L

CLASSIFICATION OF EXCRETA DISPOSAL METHODS ⭐

EXCRETA DISPOSAL
│
├── UNSEWERED AREAS
│   ├── 1. Service Type (Conservancy System)
│   └── 2. Non-Service Type (Sanitary Latrines)
│       ├── Borehole latrine
│       ├── Pit latrine
│       ├── Water-seal latrines (PRAI, RCA, Sulabh)
│       ├── Septic tank
│       └── Aqua privy
│
└── SEWERED AREAS
    └── Water-Carriage System + Sewage Treatment
        ├── Primary Treatment
        ├── Secondary Treatment
        └── Final Disposal

UNSEWERED AREAS

1. Service Type (Conservancy System)

Nightsoil collected from bucket/pail latrines by human agency
Transported in carts; disposed by burying or composting
Disadvantage: Unhygienic, manpower-dependent, odour, fly nuisance
Now being phased out under Swachh Bharat Mission

2. Non-Service Type (Sanitary Latrines)

A. Borehole Latrine

Circular pit, 75 cm diameter, 3-3.5 m deep
Concrete squatting plate on top
Suitable for: Rural areas, temporary use
Limitation: Risk of groundwater contamination; pit full in 1-2 years

B. Pit Latrine (Dug-well latrine)

Simple pit dug in ground with superstructure
Depth: 1.5-3 m; Cover to prevent flies
Advantage: Low cost, no water needed
Limitation: Fly access, odour, groundwater pollution

C. Water-Seal Latrines ⭐ (Most important for exam)

All have water seal/trap that prevents flies, odour, and insects.

Type	Key Feature
PRAI type	Pour-flush; hand-flush with water
RCA type	Standard hand-flush latrine; improved version
Sulabh Shauchalaya	Low-cost pour-flush; connected to 3-ft pit; requires very little water; used in Indian slums

Sulabh Shauchalaya - invented by Patna-based firm; now maintained by Sulabh International; Rs 5/use; recommended for urban slums

D. Septic Tank ⭐⭐ (HIGH YIELD)

Definition: Underground watertight chamber where sewage undergoes anaerobic digestion.

Principle: Anaerobic decomposition of organic matter

Parts of Septic Tank:

Inlet pipe (from latrine)
Tank (2 chambers)
Scum layer (top - floating solids)
Sludge layer (bottom - settled solids)
Clear zone (middle - liquid effluent)
Outlet pipe → Sub-soil irrigation

Process:

Solids settle → sludge (digested anaerobically)
Liquid effluent → outlet → sub-soil irrigation/soak pit
Sludge desludged every 1-2 years

Requirements for Septic Tank:

Located >15 m away from water source
Tank capacity: 2 days' hydraulic retention time
Must be watertight

Advantages:

No human agency needed
Odour-free, fly-free
Low maintenance
Suitable for individual homes, schools, hospitals

Disadvantages:

Effluent needs further treatment
Not suitable for rocky/impermeable soil
Desludging required periodically

E. Aqua Privy

Watertight tank filled with water directly below the latrine seat
Drop pipe dips below water surface → water seal
Anaerobic digestion occurs inside tank
Effluent → treated by sub-soil irrigation
Suitable: Areas where septic tank or sewers cannot be provided
Requires: Regular addition of water to maintain water level

F. Chemical Closet

Metal tank with formaldehyde + quaternary ammonium compounds (disinfectant fluid)
Very limited use in India
Used in trains, aeroplanes, temporary events

SEWERED AREAS

Water-Carriage System

Sewage is carried through underground pipes (sewers) to treatment plant.

Types of sewers:

Separate system: Separate sewers for sewage and stormwater (preferred)
Combined system: Same sewer for sewage + rainwater
Partially separate system: Combination of both

SEWAGE TREATMENT ⭐⭐ (MOST IMPORTANT)

AIM:

"To stabilize organic matter so it can be safely disposed; to convert sewage into an effluent of acceptable purity."

PRIMARY TREATMENT (Physical)

Removes suspended solids and grit - 60% suspended solids removed

Step	Process	Purpose
1. Screening	Passed through coarse + fine screens	Remove large floating objects (rags, paper, plastic)
2. Removal of grit	Grit chamber - slow flow	Removes sand, gravel, cinders
3. Plain Sedimentation	Sewage held in tank 1-2 hours	Suspended solids settle as sludge

Sludge produced → sent to sludge digestion tank
Effluent → goes to secondary treatment

SECONDARY TREATMENT (Biological) ⭐

Removes dissolved organic matter by biological action - 90% BOD removed

A. Trickling Filter (Biological Filter)

Effluent trickled over bed of broken stones/gravel (1.8-3 m deep)
Aerobic bacteria on stone surface oxidize organic matter
Air circulates through voids → aerobic conditions
Effluent collected at bottom → humus tank → settles

Advantage: Simple, low cost, efficient

B. Activated Sludge Process

Effluent mixed with activated sludge (rich in aerobic bacteria) in aeration tank
Air blown into mixture for 6-8 hours → aerobic bacteria digest organic matter
Mixed liquor → final settling tank → sludge settles
Part of sludge recycled (activated sludge) → rest sent to digestion tank

Advantage: More efficient than trickling filter; handles large volumes

SLUDGE TREATMENT

Sludge from primary + secondary → Sludge Digestion Tank
Anaerobic digestion for 30 days at 35°C
Produces biogas (methane) - used as fuel
Digested sludge → dried on sludge drying beds → used as manure/fertilizer

FINAL DISPOSAL (Effluent Disposal) ⭐

Method	Details
Sea outfall	Treated effluent discharged into sea via long pipe; dilution by sea water
River outfall	Discharged into river; must meet standards (BOD < 20 mg/L, DO > 4 mg/L)
Sewage farming	Effluent used to irrigate agricultural land; nutrients benefit crops; risk of transmission of parasites
Oxidation ponds (Waste stabilization ponds)	Shallow ponds (1-1.5 m deep); sunlight + algae + bacteria → aerobic decomposition; simple, low-cost; suitable for rural areas/tropics

OXIDATION PONDS ⭐ (Exam Favourite)

Definition: Shallow ponds (1-1.5 m) for biological treatment using sunlight, algae, and bacteria

Principle: Symbiotic relationship between algae and bacteria

Algae produce O₂ by photosynthesis → bacteria use O₂ to oxidize sewage
Bacteria release CO₂ + nutrients → algae use them for growth

Advantages:

Very low cost
No machinery required
Effective in tropical climates (India)
BOD reduced by 70-80%

Disadvantages:

Large land area required
Odour problems
Effectiveness depends on sunlight and temperature
Mosquito breeding possible

SWACHH BHARAT MISSION (SBM) ⭐

Launched: 2nd October 2014

👩‍⚕️ COMMUNITY HEALTH NURSING - APPROACHES, CONCEPTS, ROLES & RESPONSIBILITIES

BSc Nursing 5th Sem | Community Health Nursing - I | RGUHS

Source: Park's Textbook | INC Curriculum

DEFINITION OF COMMUNITY HEALTH NURSING

Community Health Nursing is a synthesis of nursing practice and public health practice applied to promote and preserve the health of the population. It is directed towards the whole population - individuals, families, and communities.

SECTION A: APPROACHES IN COMMUNITY HEALTH NURSING

1. NURSING PROCESS APPROACH ⭐

Definition: A systematic, scientific, problem-solving method used by nurses to deliver individualized, goal-directed nursing care.

5 Steps (ADPIE):

Step	Activity
A - Assessment	Collect data (subjective + objective) about individual/family/community health
D - Diagnosis	Identify health problems (nursing diagnoses)
P - Planning	Set goals, plan interventions, prioritize problems
I - Implementation	Carry out the planned nursing care
E - Evaluation	Assess if goals were achieved; revise plan if needed

Application in CHN:

Assess community health needs
Identify priority health problems
Plan and implement health programs
Evaluate outcome of nursing interventions

2. EPIDEMIOLOGICAL APPROACH ⭐⭐

Definition: Application of epidemiological principles to study the distribution, determinants, and control of health problems in a community.

Steps:

Define the problem - What disease/health issue?
Measure the problem - Incidence, prevalence, morbidity, mortality rates
Identify determinants - Agent, Host, Environment (Epidemiological Triad)
Generate hypothesis - Possible causes
Test hypothesis - Studies (case-control, cohort)
Apply findings - Intervention, prevention, control
Evaluate - Impact of interventions

Tools used:

Epidemiological triad (Agent-Host-Environment)
Natural history of disease
Levels of prevention (Primary, Secondary, Tertiary)
Disease surveillance

Role of CHN in Epidemiological approach:

Disease surveillance and reporting
Case finding and contact tracing
Community assessment and surveys
Outbreak investigation

3. PROBLEM-SOLVING APPROACH ⭐

Definition: A logical, systematic method to identify, analyze, and find solutions to health problems.

Steps:

Identify and define the problem clearly
Gather data/information about the problem
Analyze the problem - causes and contributing factors
Generate possible solutions/alternatives
Select the best solution
Implement the solution
Evaluate results and revise if needed

Difference from Nursing Process: Problem-solving is broader; nursing process is specific to nursing care delivery.

4. EVIDENCE-BASED APPROACH (EBP) ⭐

Definition: Integration of best available research evidence with clinical expertise and patient values in making health care decisions.

Steps of EBP (5 A's):

Step	Action
Ask	Formulate a clinical question (PICO format)
Acquire	Search for relevant evidence (journals, databases)
Appraise	Critically evaluate the evidence for validity
Apply	Apply evidence to the specific patient/community
Assess	Evaluate outcomes after application

PICO Format:

P - Patient/Population/Problem
I - Intervention
C - Comparison
O - Outcome

Why important for CHN?

Ensures nursing practice is based on current, valid research
Improves quality of care
Reduces outdated practices
Guides policy decisions

5. EMPOWERING PEOPLE TO CARE FOR THEMSELVES ⭐

Definition: The process of enabling individuals, families, and communities to take control of their own health through knowledge, skills, and resources.

Concepts:

Self-care
Health literacy
Community participation
Capacity building

Strategies:

Health education and counseling
Teaching self-monitoring skills (BP, blood sugar)
Community organizing and mobilization
Peer support groups
Training community health workers (ASHA, AWW)
Facilitating access to resources

Role of CHN in Empowerment:

Educator and facilitator (not just provider)
Teaches families to identify their own health needs
Builds self-reliance in health decision-making
Supports self-help groups (SHG) and community action

SECTION B: PRIMARY HEALTH CARE (PHC) & CPHC

PRIMARY HEALTH CARE (PHC) ⭐⭐ (High Yield)

Definition (Alma-Ata, 1978):

"Essential health care based on practical, scientifically sound and socially acceptable methods and technology made universally accessible to individuals and families in the community."

Alma-Ata Declaration:

Declared at International Conference on PHC, Alma-Ata, USSR, September 1978
Theme: "Health for All by 2000 A.D."
Organized by WHO + UNICEF
India was a signatory

Principles of PHC (JEACIS):

Principle	Meaning
Justice/Equity	Health care available to ALL without discrimination
Efficiency	Cost-effective use of resources
Accessibility	Services available at first level of contact
Community Participation	People involved in planning & implementation
Intersectoral Coordination	Health + Agriculture + Education + Water departments working together
Self-reliance	Building community capacity for own health

8 Essential Elements of PHC (Mnemonic: "TEETH MF" or "MESH FTEd"):

Education about prevailing health problems and methods of prevention/control
Food supply and proper nutrition
Safe water and basic sanitation
MCH including family planning
Immunization against major infectious diseases
Prevention and control of locally endemic diseases
Treatment of common diseases and injuries
Essential drugs supply

COMPREHENSIVE PRIMARY HEALTH CARE (CPHC) ⭐

New concept under National Health Policy 2017 and Ayushman Bharat (2018)

Definition: CPHC expands PHC beyond just curative services to include promotive, preventive, curative, rehabilitative, and palliative care for a comprehensive range of health services.

3 Key Components of CPHC (WHO, 2018 Astana Declaration):

Primary care and essential public health functions as the core of integrated health services
Multi-sectoral policy and action to address broader determinants of health
Empowered people and communities

CPHC under Ayushman Bharat:

Health and Wellness Centres (HWCs) - upgraded Sub-centres and PHCs
Provide 12 packages of care (including mental health, palliative care, geriatric care, dental care, ophthalmology, ENT)
Target: 1.5 lakh HWCs by 2022

Difference: PHC vs CPHC:

PHC	CPHC
Focus on 8 essential elements	Broader package including NCD management
Sub-centre/PHC level	Health and Wellness Centres
Primarily rural	Rural + Urban
Curative + basic preventive	Full continuum of care

SECTION C: HOME VISITS

CONCEPT OF HOME VISIT ⭐⭐

Definition:

Home visit is a professional visit by the community health nurse to the home of the individual/family to identify and prioritize health needs and provide care in their natural environment using available resources.

3 Dimensions of UHC:

Population coverage - Who is covered? (everyone)
Service coverage - Which services? (all essential health services)
Financial protection - Costs covered? (no out-of-pocket burden)

UHC Cube (WHO model):

         ↑ Reduce cost sharing
         │ (financial protection)
         │
         │_____________→ Extend to non-covered
         /  (population)
        /

PART 1: SANITATION

1. CONCEPT OF ENVIRONMENTAL HEALTH & SANITATION

Environment: All external conditions (chemical, physical, biotic) that act on an organism or community and influence survival, development, and evolution.

Environmental Health (WHO): The aspects of human health and disease that are determined by factors in the environment. It refers to theory and practice of assessing and controlling factors in the environment that can potentially affect health.

Sanitation: The practice of maintaining clean and hygienic conditions to prevent disease and promote health. Includes safe water supply, waste disposal, clean housing, and personal hygiene.

Environmental Sanitation: Control of all environmental factors that could have a harmful effect on human physical, mental, or social well-being.

2. SAFE WATER ⭐⭐

Sources of Water:

Category	Sources
Surface water	Rivers, lakes, ponds, streams
Ground water	Wells (dug, tube), springs, artesian wells
Rainwater	Collected from rooftops, direct rainfall
Municipal supply	Treated piped water supply

Waterborne Diseases ⭐

Disease	Causative Agent	Transmission
Typhoid	Salmonella typhi	Fecal-oral via contaminated water/food
Cholera	Vibrio cholerae	Contaminated water
Dysentery	Shigella / E. histolytica	Contaminated water/food
Hepatitis A	HAV	Fecal-oral via water
Polio	Poliovirus	Fecal-oral via water
Diarrhoea	E. coli, Rotavirus	Contaminated water/food
Dracunculiasis	Guinea worm	Drinking water with infected cyclops
Fluorosis	Excess fluoride in water	High fluoride in ground water
Arsenicosis	Excess arsenic	Arsenic in groundwater

"F diagram" for waterborne transmission: Faeces → Fingers → Flies → Food → Fluid → New Host

Water Purification Processes ⭐⭐

Large-scale (Municipal) Purification:

RAW WATER (River/Lake)
     ↓
1. SEDIMENTATION (plain settling, 24-36 hrs) → Removes suspended solids
     ↓
2. COAGULATION + FLOCCULATION
   (Alum = Aluminium sulphate added) → Forms floc; settles impurities
     ↓
3. FILTRATION
   (Slow sand filter OR Rapid sand filter) → Removes bacteria, turbidity
     ↓
4. DISINFECTION (CHLORINATION)
   (Chlorine added - residual 0.5 mg/L after 30 min contact time) → Kills bacteria/viruses
     ↓
SAFE DRINKING WATER ✅

Types of Filters:

Feature	Slow Sand Filter	Rapid Sand Filter
Rate	0.1-0.4 m/hr	4-5 m/hr (40x faster)
Removes bacteria	98-99%	98-99% with coagulation
Cleaning	Scraping top sand layer	Backwashing
Land needed	Large	Less
Cost	Low	Higher
Schmutzdecke	Present (biological film - kills bacteria)	Absent

Schmutzdecke = Biological film on slow sand filter = "the heart of the filter"

Household Purification of Water ⭐

Method	Process	Key Points
Boiling	Boil for 10-20 min	Most effective; kills ALL pathogens; easy, cheap

Here are complete, exam-oriented notes on Sewage Disposal System — sharp and easy to revise:

🚽 SEWAGE DISPOSAL SYSTEM

BSc Nursing 5th Sem | Community Health Nursing - I | RGUHS

DEFINITIONS ⭐

Term	Definition
Sewage	Wastewater from a community containing solid + liquid excreta from houses, streets, factories, and industries
Sullage	Wastewater WITHOUT human excreta (kitchen, bathroom waste only)
Nightsoil	Human excreta collected from bucket/pail latrines
Dry Weather Flow	Average quantity of sewage flowing through sewers in 24 hours
Sludge	Settled solids at bottom of sewage treatment tanks
Effluent	Liquid discharged after sewage treatment

Key fact: Sewage = 99.9% water + 0.1% solids (organic + inorganic)

PUBLIC HEALTH IMPORTANCE ⭐

Improper excreta/sewage disposal causes:

FAECES
  ↓
┌─────────────────────────────┐
│  5 Fs of Faecal Transmission│
│  Fingers → Flies → Food     │
│  Fluid (water) → Fields     │
└─────────────────────────────┘
  ↓
NEW HOST → DISEASE

Diseases caused:

Typhoid, Paratyphoid
Cholera, Dysentery, Diarrhoea
Hepatitis A
Hookworm, Ascariasis
Viral gastroenteritis

SANITATION BARRIER = Breaking the cycle by providing sanitary latrine + disposal pit/sewage treatment

BOD — BIOCHEMICAL OXYGEN DEMAND ⭐⭐

"Standard indicator of organic content of sewage"

BOD Level	Interpretation
100 mg/L	Weak sewage
200 mg/L	Medium sewage
≥300 mg/L	Strong sewage

AIM of treatment: Reduce BOD to safe levels
Treated effluent discharged to river must have: BOD < 20 mg/L + Dissolved O₂ > 4 mg/L

UNSEWERED AREAS

1. SERVICE TYPE (CONSERVANCY SYSTEM)

Nightsoil collected from bucket/pail latrines by human agency
Transported in carts; disposed by burying or composting
❌ Unhygienic — causes odour, fly nuisance, disease spread
Being phased out under Swachh Bharat Mission

2. NON-SERVICE TYPE (SANITARY LATRINES)

A. Borehole Latrine

Circular pit: 75 cm diameter, 3-3.5 m deep
Concrete squatting plate on top
Suitable for rural/temporary use
❌ Limitation: groundwater contamination risk

B. Pit Latrine (Dug-well)

Simple pit, 1.5-3 m deep
Low cost, no water needed
❌ Fly access, odour, groundwater pollution

C. Water-Seal Latrines ⭐ (Pour-flush type)

Key Feature: Water trap prevents flies, odour, insects from entering

Type	Feature
PRAI type	Pour-flush, hand-flush with water
RCA type	Standard hand-flush; improved version
Sulabh Shauchalaya	Low-cost pour-flush; 3-ft pit; very little water needed

Sulabh Shauchalaya: Invented by Patna-based firm (Sulabh International) | Used in Indian slums | Rs 5 per use | Recommended for urban areas

D. SEPTIC TANK ⭐⭐ (HIGH YIELD — Most Asked)

Definition: Underground, watertight tank where sewage undergoes anaerobic digestion

Principle: Anaerobic decomposition of organic matter

Structure of Septic Tank:

INLET PIPE (from latrine)
        ↓
┌─────────────────────────┐
│ SCUM (floating layer)   │  ← Fats, oils, grease
│─────────────────────────│
│ CLEAR ZONE (liquid)     │  ← Effluent flows out
│─────────────────────────│
│ SLUDGE (settled solids) │  ← Anaerobic digestion here
└─────────────────────────┘
        ↓
OUTLET PIPE → Sub-soil irrigation / Soak pit

Siting Requirements:

Located minimum 15 m away from water source
Must be watertight — no leakage

Maintenance:

Desludging every 1-2 years (remove accumulated sludge)
Vent pipe for gas escape (methane)

Advantages: ✅ No human agency needed ✅ Odour-free, fly-free ✅ Suitable for homes, schools, hospitals ✅ Low maintenance

Disadvantages: ❌ Effluent needs sub-soil treatment ❌ Not suitable for rocky/impermeable soil ❌ Periodic desludging required

E. Aqua Privy

Watertight tank filled with water directly below latrine seat
Drop pipe dips below water surface = water seal
Anaerobic digestion inside tank
Effluent → sub-soil irrigation
Suitable where septic tank/sewers not feasible

F. Chemical Closet

Metal tank with formaldehyde + quaternary ammonium compounds
Deodorizing substance added
Very limited use in India (trains, aircraft, temporary events)

G. Latrines for Camps / Temporary Use

Type	Details
Shallow trench	30 cm wide, 90-150 cm deep; cover with earth after use; for up to 1 week
Deep trench	45 cm wide, 1.8 m deep; more durable; 3-6 months
Bore hole	Quick to dig; drill-type; temporary camps

SEWERED AREAS — WATER CARRIAGE SYSTEM

SEWAGE TREATMENT ⭐⭐⭐ (MOST IMPORTANT)

AIM:

"To stabilize organic matter so it can be safely disposed; to convert sewage into an effluent of acceptable purity"

▶ PRIMARY TREATMENT (Physical) ⭐

Removes: Floating solids + Suspended solids BOD removed: ~30-35%

Step	Process	What is Removed
1. Screening	Coarse + fine screens	Rags, paper, plastic, large objects
2. Grit Chamber	Slows flow velocity	Sand, gravel, cinders
3. Plain Sedimentation	Sewage held 1-2 hours	Suspended solids settle → PRIMARY SLUDGE

▶ SECONDARY TREATMENT (Biological) ⭐⭐

Removes: Dissolved organic matter by biological oxidation BOD removed: ~85-90%

A. TRICKLING FILTER (Biological Filter)

EFFLUENT (from primary)
        ↓
Distributed over BED OF BROKEN STONES (1.8-3 m deep)
        ↓
Aerobic bacteria on stone surface oxidize organic matter
(Air circulates through gaps)
        ↓
Treated effluent collected at bottom
        ↓
HUMUS TANK (secondary sedimentation) → sludge settles
        ↓
FINAL EFFLUENT

Simple, low-cost, no electricity needed
Aerobic process

B. ACTIVATED SLUDGE PROCESS ⭐

EFFLUENT (from primary)
        ↓
AERATION TANK
(mixed with activated sludge)
        + AIR BLOWN IN for 6-8 hours
        + Aerobic bacteria digest organic matter
        ↓
FINAL SETTLING TANK
        ↓
     ┌──────────────────────┐
     ↓                      ↓
EFFLUENT            SLUDGE settles
(discharged)               ↓
                  Some recycled as
                  "ACTIVATED SLUDGE"
                  back to aeration tank
                  (rest → SLUDGE DIGESTION)

More efficient than trickling filter
Handles large volumes
Requires electricity for aeration

Comparison: Trickling Filter vs Activated Sludge

Feature	Trickling Filter	Activated Sludge
Process	Aerobic (film)	Aerobic (suspended)
Efficiency	Good	Better
Cost	Low	Higher
Land needed	More	Less
Maintenance	Simple	Complex
Electricity	Not needed	Required

▶ SLUDGE TREATMENT ⭐

Sludge (from primary + secondary settling)
        ↓
SLUDGE DIGESTION TANK
(Anaerobic, 35°C, 30 days)
        ↓
Produces BIOGAS (methane) → Used as fuel
        ↓
Digested sludge → SLUDGE DRYING BEDS
        ↓
Dried sludge cake → Used as MANURE/FERTILIZER

▶ FINAL DISPOSAL OF EFFLUENT ⭐

Method	Details	Key Points
Sea outfall	Effluent discharged to sea via long pipe	Diluted by sea; offshore discharge
River outfall	Discharged to river after full treatment	BOD <20 mg/L; DO >4 mg/L
Sewage farming	Effluent used for crop irrigation	Nutrients benefit crops; ⚠️ parasite risk
Oxidation ponds	Shallow ponds using sunlight + algae + bacteria	Simple, cheap; suited for tropics

OXIDATION PONDS (Waste Stabilization Ponds) ⭐⭐

Definition: Shallow ponds (1-1.5 m deep) for biological treatment using sunlight, algae, and bacteria

Principle — Algae-Bacteria Symbiosis:

CO₂ + nutrients + sunlight
        ↓
ALGAE (photosynthesis) → O₂
        ↓
BACTERIA use O₂ to oxidize sewage
        ↓
Release CO₂ + nutrients → back to algae
(Cycle continues)

BOD removal: 70-80%

Advantages: ✅ Very low cost ✅ No machinery/electricity needed ✅ Effective in tropical climates (India) ✅ Can treat raw sewage

Disadvantages: ❌ Large land area required ❌ Odour problems ❌ Weather-dependent ❌ Possible mosquito breeding

TYPES OF SEWER SYSTEMS

System	Description
Separate system	Separate sewers for sewage + stormwater ✅ PREFERRED
Combined system	One sewer for both sewage + rainwater
Partially separate	Combination of both
