Antenatal Care (ANC) under RMNCAH+N
1. Definition
Antenatal care (ANC) is the planned, regular care of a pregnant woman from confirmation of pregnancy until the onset of labour. It includes:
- Early registration of pregnancy
- Regular maternal and fetal assessment
- Screening for anemia, infections, hypertension, diabetes, and other complications
- Preventive interventions such as iron-folic acid, calcium, tetanus-diphtheria immunization, and deworming
- Nutrition, lifestyle, danger-sign, and birth-preparedness counselling
- Identification, referral, and follow-up of high-risk pregnancy
- Linkage with safe institutional delivery, postnatal care, newborn care, breastfeeding, and family planning
ANC is not merely weighing the mother or performing blood and urine tests. It is a continuous, respectful relationship that prepares the woman and family for a safe pregnancy, birth, and postnatal period.
2. ANC in RMNCAH+N
RMNCAH+N means:
- R - Reproductive health
- M - Maternal health
- N - Newborn health
- C - Child health
- A - Adolescent health
- H - Health
- +N - Nutrition
ANC is a core maternal-health intervention within this strategy. It provides care across the continuum:
| Period | ANC linkage |
|---|
| Pre-pregnancy | Family planning, delaying early marriage and first pregnancy, folic acid, nutrition, management of chronic disease |
| Pregnancy | ANC, nutrition, prevention of anemia, high-risk screening, birth preparedness |
| Labour and birth | Skilled birth attendance, institutional delivery, emergency obstetric care |
| Postnatal period | Maternal check-up, breastfeeding, postpartum family planning, newborn care |
| Infancy and childhood | Immunization, growth monitoring, nutrition, early childhood development |
| Adolescence | Nutrition, anemia control, menstrual and sexual-reproductive health education |
Goals of ANC
- Ensure a healthy mother and healthy baby.
- Detect high-risk pregnancy and complications early.
- Prevent maternal, fetal, and neonatal morbidity and mortality.
- Treat or refer complications promptly.
- Prevent anemia, tetanus, infections, and nutritional deficiencies.
- Promote institutional delivery and skilled birth attendance.
- Prepare the woman and family for birth, emergencies, breastfeeding, and postnatal family planning.
- Ensure respectful, dignified, woman-centred maternity care.
3. Objectives of ANC
A. Maternal objectives
- Confirm pregnancy and estimate gestational age.
- Calculate the expected date of delivery (EDD).
- Assess maternal nutritional and general health status.
- Detect anemia, hypertensive disorders, diabetes, infections, and medical disorders.
- Prevent or treat nutritional deficiencies.
- Identify psychosocial problems, mental-health concerns, substance use, domestic violence, and social support needs.
- Provide health education and counselling.
B. Fetal objectives
- Confirm fetal viability and assess fetal growth.
- Identify multiple pregnancy, growth restriction, congenital anomalies, malpresentation, and fetal distress.
- Monitor fetal movements in later pregnancy.
- Plan referral if fetal or maternal risk is identified.
4. Timing of Registration and ANC Visits
Early registration
Every pregnancy should be registered as soon as it is suspected, preferably within the first 12 weeks of gestation.
Early registration permits:
- Accurate dating of pregnancy
- Baseline investigations
- Prompt treatment of anemia and infections
- Timely preventive interventions
- Early recognition of high-risk pregnancy
- Better birth planning and continuity of care
Indian public-health schedule
The traditional Indian service schedule ensures at least four ANC check-ups, including the first registration visit:
| Visit | Recommended timing |
|---|
| 1st ANC / registration | Within 12 weeks, preferably immediately after pregnancy is suspected |
| 2nd ANC | 14-26 weeks |
| 3rd ANC | 28-36 weeks |
| 4th ANC | 36 weeks to term |
| PMSMA check-up | At least once in the 2nd or 3rd trimester, on the 9th of the month |
The National Health Systems Resource Centre training manual specifies this four-visit schedule and advises a PMSMA visit in the second or third trimester. It also lists full ANC as including history, physical and abdominal examination, laboratory tests, IFA, Td, counselling, and birth planning.
NHSRC ANC manual
WHO contact model
WHO recommends a minimum of eight ANC contacts:
- First contact: within 12 weeks
- Then at: 20, 26, 30, 34, 36, 38, and 40 weeks
A “contact” is more than a brief visit. It includes assessment, counselling, preventive care, and a chance for the woman to discuss concerns. WHO advises that eight contacts improve the pregnancy experience and enable earlier detection of complications.
WHO ANC recommendations
Exam point: Write the national four-check-up schedule for Indian public-health programmes, and mention that WHO advocates eight contacts.
5. Components of the First ANC Visit
The first visit should be comprehensive, irrespective of the gestation at which the woman first presents.
A. Registration and records
- Register in the appropriate maternal/RCH record.
- Issue and explain the Mother and Child Protection Card where used.
- Record contact details and address.
- Ensure name-based tracking and follow-up by the health team.
- Record obstetric score:
- Gravida (G)
- Para (P)
- Abortions (A)
- Living children (L)
- Calculate gestational age and EDD.
B. Estimation of EDD
Naegele’s rule:
EDD = First day of LMP + 9 months + 7 days
This assumes a regular 28-day menstrual cycle. Early ultrasound dating may be needed when LMP is uncertain, cycles are irregular, or clinical findings do not match the calculated gestation.
Park’s Textbook of Preventive and Social Medicine describes recording the LMP and calculating EDD by adding nine months and seven days. - Park’s Textbook of Preventive and Social Medicine, p. 612
C. History taking
1. Present pregnancy history
Ask about:
- LMP and menstrual regularity
- Pregnancy confirmation
- Nausea, vomiting, fever, abdominal pain
- Vaginal bleeding or watery discharge
- Abnormal vaginal discharge
- Burning micturition
- Severe headache, visual disturbance, facial swelling
- Palpitations, fatigue, breathlessness
- Convulsions
- Decreased or absent fetal movement after quickening
- Medication use, allergies, radiation exposure, tobacco, alcohol, or other substance use
2. Previous obstetric history
Ask about:
- Previous abortions, ectopic pregnancy, stillbirth, neonatal death
- Preterm birth
- Low-birth-weight baby
- Previous caesarean section or instrumental delivery
- Postpartum haemorrhage
- Eclampsia or pre-eclampsia
- Gestational diabetes
- Previous congenital anomaly
- Rh isoimmunization
- Multiple pregnancy
- Previous baby with developmental delay or inherited disorder
3. Medical and surgical history
Screen for:
- Hypertension
- Diabetes mellitus
- Heart disease
- Renal disease
- Thyroid disease
- Epilepsy
- Asthma
- Tuberculosis
- Hepatitis/jaundice
- HIV and sexually transmitted infections
- Malaria in endemic areas
- Previous surgery, especially uterine surgery
4. Family history
- Hypertension and diabetes
- Twins
- Thalassemia or other hemoglobinopathies
- Congenital anomalies
- Genetic disorders
5. Personal and social history
- Diet and food insecurity
- Tobacco, alcohol, and drugs
- Occupation and excessive physical work
- Domestic violence or lack of family support
- Economic difficulty and access to transport
- Mental-health symptoms, including low mood, anxiety, or suicidal thoughts
6. Physical Examination at ANC
A. General examination
Perform at every visit as relevant:
| Parameter | Importance |
|---|
| Weight | Assesses nutritional status and weight gain trend |
| Height | Short stature may suggest risk of cephalopelvic disproportion |
| Pulse | Persistent tachycardia/bradycardia needs assessment |
| Blood pressure | Screens for gestational hypertension and pre-eclampsia |
| Pallor | Suggests anemia; correlate with Hb |
| Edema | Facial/hand edema or edema with high BP/proteinuria is concerning |
| Respiratory rate | Important in breathlessness, infection, heart disease, severe anemia |
| Temperature | Detects fever/infection |
| Breast examination when indicated | Supports breastfeeding counselling and identifies concerns |
| Thyroid, cardiac, respiratory examination | Performed if symptoms or history suggest disease |
Blood pressure should be measured at every ANC visit. Edema associated with hypertension, proteinuria, anemia, or heart disease requires medical evaluation. - Park’s Textbook of Preventive and Social Medicine, p. 612-613
B. Abdominal examination
Usually becomes more informative after about 20 weeks.
Assess:
-
Inspection
- Abdominal size and shape
- Scars from previous surgery
- Striae, skin condition, visible fetal movements
-
Fundal height
- Measure symphysis-fundal height, usually from 20 weeks onward.
- Plot serial measurements where a growth chart is used.
- A discrepancy may suggest wrong dates, multiple pregnancy, polyhydramnios, oligohydramnios, or fetal growth restriction.
-
Palpation
- Uterine size
- Fetal lie: longitudinal, transverse, oblique
- Presentation: cephalic, breech, shoulder
- Position
- Engagement of presenting part
- Tenderness or uterine contractions
-
Auscultation
- Fetal heart rate, normally about 110-160 beats/minute.
- Assess after fetal viability, often with Doppler where available.
C. Pelvic examination
Not routinely required in every woman. Perform only when clinically indicated, such as:
- Vaginal bleeding
- Pain or suspected abortion/ectopic pregnancy
- Vaginal infection symptoms
- Suspected rupture of membranes
- Assessment near labour where appropriate
- Cervical screening or other specific indication
Always obtain consent, maintain privacy, and use respectful communication.
7. Investigations in ANC
Investigations may differ by local guidelines and availability, but the following are generally important.
At booking or first visit
| Test | Purpose |
|---|
| Hemoglobin estimation | Detect and grade anemia |
| Blood group and Rh type | Identify Rh-negative mother; prepare transfusion planning |
| Urine albumin/protein | Screen for proteinuria, especially with hypertension |
| Urine sugar | Screen for glycosuria/possible diabetes |
| Urine microscopy/culture if indicated | Diagnose urinary infection/asymptomatic bacteriuria |
| HIV test with informed consent and counselling | Enable prevention of mother-to-child transmission and maternal treatment |
| Syphilis screening | Prevent congenital syphilis through timely treatment |
| Hepatitis B screening | Enables maternal and newborn prevention measures |
| Blood glucose screening | Screen for diabetes/gestational diabetes as per local protocol |
| Ultrasound | Confirm dating, viability, multiple pregnancy, placental location and fetal anatomy as appropriate |
Repeat or follow-up investigations
May include:
- Repeat Hb in later pregnancy, particularly where anemia is prevalent.
- Repeat urine protein and blood pressure monitoring at each visit.
- Repeat HIV/syphilis testing based on local policy or ongoing risk.
- Diabetes testing at the recommended gestational period if not done earlier.
- Growth ultrasound or Doppler only when indicated, for example suspected fetal growth restriction, hypertension, decreased fetal movement, or multiple pregnancy.
WHO recommends one ultrasound scan
before 24 weeks, mainly to estimate gestation, identify multiple pregnancy, detect anomalies, and improve management of post-term pregnancy.
WHO guidance
8. Routine Preventive Interventions
A. Iron-folic acid (IFA) supplementation
Purpose
IFA prevents and treats iron-deficiency anemia and supports fetal development. Folic acid taken before conception and in early pregnancy reduces neural-tube defects.
Common Indian programme approach
- At least 180 IFA tablets during pregnancy are provided under public-health programmes.
- A commonly used tablet contains 60 mg elemental iron plus 500 micrograms folic acid.
- It is generally started after the first trimester or as per local programme protocol, and taken daily.
Counselling for adherence
- Take after meals if gastric irritation occurs.
- Black stools, nausea, constipation, and mild abdominal discomfort can occur.
- Do not stop solely because stools turn black.
- Take with water and a vitamin C-rich food where possible.
- Avoid taking it at the same time as tea, coffee, or calcium, because absorption may be reduced.
- Assess adherence at every visit.
If anemia is detected
- Classify severity by Hb and follow national protocol.
- Look for likely causes: dietary deficiency, malaria where endemic, hemoglobinopathy, worm infestation, chronic disease, or bleeding.
- Severe anemia, symptomatic anemia, late-pregnancy anemia, or anemia with cardiac symptoms requires urgent medical assessment and possible referral.
B. Calcium supplementation
Purpose
Calcium supplementation helps improve maternal calcium intake and is used in programmes to reduce risks related to low dietary calcium intake, including hypertensive disorders of pregnancy.
Common Indian public-health approach
- 1 g elemental calcium daily, often supplied as two 500 mg doses.
- Usually started from the second trimester, commonly around 14 weeks, and continued until delivery.
- Keep a time gap, commonly at least 2 hours, between calcium and IFA to avoid reducing iron absorption.
C. Tetanus-diphtheria immunization
Pregnant women should receive Td vaccination according to their previous immunization history.
A common schedule is:
| Situation | Td schedule |
|---|
| Previously unvaccinated or status unknown | Td-1 early in pregnancy, Td-2 at least 4 weeks later |
| Adequately vaccinated in a recent previous pregnancy | Td booster dose as per national schedule |
Purpose:
- Protects the mother against tetanus and diphtheria.
- Prevents maternal and neonatal tetanus.
D. Deworming
In areas where soil-transmitted helminths are prevalent, a single dose of albendazole 400 mg may be given after the first trimester, according to national policy.
Do not give routine deworming in the first trimester unless specifically prescribed for a compelling clinical indication.
E. Malaria prevention
In malaria-endemic areas:
- Promote insecticide-treated bed nets.
- Test fever promptly for malaria.
- Give treatment or intermittent preventive therapy only according to local/national malaria guidelines.
F. Prevention of mother-to-child transmission of HIV
- Offer HIV testing with consent and counselling.
- If HIV-positive, promptly link the woman to antiretroviral therapy and HIV services.
- Plan delivery, newborn prophylaxis, infant testing, and feeding support according to the national programme.
9. Nutrition During Pregnancy
A. Basic dietary advice
A pregnant woman should eat a balanced, diverse diet, not simply “eat for two.”
Encourage foods from all groups:
- Cereals and millets
- Pulses, beans, nuts, soy products
- Green leafy vegetables
- Other vegetables and fruits
- Milk and milk products
- Eggs, fish, or meat for those who consume them
- Iodized salt
- Adequate safe water
B. Nutrition goals
- Prevent maternal undernutrition, anemia, and micronutrient deficiency.
- Support appropriate weight gain.
- Improve fetal growth.
- Reduce risk of low birth weight.
The cited Indian training manual advises food from all five food groups and describes an expected total pregnancy weight gain of approximately
10-12 kg for many women, though individual goals should depend on pre-pregnancy BMI, multiple pregnancy, and medical conditions.
NHSRC training guidance
C. Avoid or limit
- Tobacco in all forms
- Alcohol and recreational drugs
- Unprescribed medicines and herbal products
- Unsafe, unpasteurized foods
- Undercooked meat, eggs, and fish
- Excess caffeine
- Excessively strenuous physical work
- Exposure to second-hand smoke
10. Health Education and Counselling
Counselling should be repeated, understandable, culturally appropriate, and involve the partner/family only with the woman’s consent.
Topics for every pregnant woman
- Importance of regular ANC.
- Compliance with IFA and calcium.
- Balanced diet and adequate fluids.
- Rest, sleep, hygiene, and moderate physical activity.
- Avoidance of tobacco, alcohol, and non-prescribed drugs.
- Recognition of danger signs.
- Institutional delivery and skilled birth attendance.
- Birth preparedness and emergency transport.
- Breastfeeding, especially early initiation and exclusive breastfeeding for six months.
- Postpartum contraception.
- Newborn care, immunization, and postnatal check-ups.
- Mental wellbeing and family support.
11. Danger Signs During Pregnancy
A woman and her family must be told to seek care immediately if any danger sign occurs.
Major danger signs
- Vaginal bleeding at any stage of pregnancy
- Severe abdominal pain
- Severe or persistent headache
- Blurring of vision, flashing lights, or altered consciousness
- Convulsions/fits
- Sudden swelling of face or hands
- Severe breathlessness, chest pain, or palpitations
- High fever or chills
- Persistent vomiting with inability to retain food or fluids
- Leaking of fluid per vagina before labour
- Foul-smelling vaginal discharge
- Pain/burning during urination with fever or flank pain
- Decreased or absent fetal movements after they have been felt regularly
- Labour pains before 37 weeks
- Severe weakness, fainting, or marked pallor
- Jaundice
Key message: Do not wait for the next scheduled ANC appointment. Arrange referral or emergency care immediately.
12. High-Risk Pregnancy
Definition
A high-risk pregnancy is one in which the mother, fetus, or newborn has an increased risk of illness, disability, or death before, during, or after birth.
High-risk identification is not a one-time task. Risk must be reassessed at every ANC contact.
A. Maternal demographic and obstetric risks
- Age below 18 years

- Previous stillbirth, neonatal death, recurrent abortion, ectopic pregnancy
- Previous preterm birth or low-birth-weight baby
- Previous caesarean section
- Previous postpartum haemorrhage
- Previous eclampsia/pre-eclampsia
- Previous baby with congenital anomaly
B. Current pregnancy risks
- Severe anemia
- Hypertension, pre-eclampsia, or eclampsia
- Diabetes or gestational diabetes
- Heart disease, renal disease, epilepsy, thyroid disease, tuberculosis
- HIV, hepatitis B, syphilis, or other significant infection
- Rh-negative mother
- Multiple pregnancy
- Malpresentation after 36 weeks
- Antepartum hemorrhage
- Placenta previa
- Oligohydramnios or polyhydramnios
- Suspected fetal growth restriction
- Reduced fetal movements
- Preterm labour or premature rupture of membranes
C. Management principles
- Identify the risk factor early.
- Explain the risk and plan with the woman and family.
- Refer to the appropriate facility.
- Ensure feedback and follow-up after referral.
- Make a specific birth plan at a suitable institution.
- Arrange transport, funds, blood donor support where required.
- Document clearly in maternal records.
Under PMSMA, women with no risk factor may be marked with a
green sticker, while high-risk pregnancy is marked with a
red sticker for identification and follow-up.
