Q-3(c): Drug Dependence vs Drug Addiction (6 marks)

Drug Dependence

1. Physical (Physiological) Dependence: The body adapts to the presence of the drug; abrupt withdrawal produces physical withdrawal symptoms (e.g., tremors, sweating, seizures with alcohol withdrawal)
2. Psychological (Psychic) Dependence: Emotional/mental need to take the drug for pleasure or to relieve discomfort; no significant physical withdrawal signs

• May exist without addiction (e.g., a patient on long-term opioids for cancer pain is physically dependent but not addicted)
• Focus is on the biological adaptation of the body

Drug Addiction

1. Compulsive craving for the drug
2. Loss of control - cannot stop despite wanting to
3. Continued use despite adverse consequences (social, occupational, medical)
4. Tolerance - need increasing amounts to achieve the same effect
5. Preoccupation with obtaining the drug
6. Relapse after periods of abstinence

Key Differences

Q-3(d): Fertility Indicators, NRR=1, Terminal Contraceptive Methods (2+1+3 = 6 marks)

Fertility Indicators (2 marks)

1. Crude Birth Rate (CBR): Number of live births per 1000 mid-year population per year
   • India CBR: ~20 (SRS 2020)
2. General Fertility Rate (GFR): Number of live births per 1000 women aged 15-44 (or 15-49) years per year
3. Age-Specific Fertility Rate (ASFR): Live births per 1000 women of a specific age group per year
4. Total Fertility Rate (TFR): Average number of children a woman would have if she experienced current age-specific fertility rates throughout her reproductive lifespan (15-49 years)
   • India TFR: 2.0 (NFHS-5, 2019-21) - at replacement level
   • Replacement level TFR = 2.1
5. Gross Reproduction Rate (GRR): Average number of girl children born to a woman during her reproductive period (15-49 years)
6. Net Reproduction Rate (NRR): Average number of girl children a woman will have who survive to reproductive age, taking into account mortality rates

NRR = 1 (1 mark)

Terminal Contraceptive Methods - Advantages and Disadvantages (3 marks)

1. Highly effective - close to 100% (failure rate: tubectomy ~0.5%, vasectomy ~0.1 per 100 woman-years)
2. One-time procedure - no need for daily/monthly compliance
3. Cost-effective in long run
4. No hormonal side effects - natural menstrual cycles and hormone levels unchanged
5. No interference with sexual intercourse, libido, or sexual pleasure
6. Immediate effect (tubectomy) - effective from the day of procedure

1. Permanent/Irreversible - reversal (recanalization) is technically difficult, expensive, and not always successful
2. Requires surgical procedure - carries surgical and anaesthetic risks (bleeding, infection, anaesthetic complications)
3. No protection against STIs/HIV
4. Regret - especially if done at young age, child death, or remarriage
5. Failure - can rarely fail (ectopic pregnancy risk in tubectomy failure)
6. Vasectomy: Small delay in effectiveness - requires semen analysis after 12 weeks to confirm azoospermia
7. Social/cultural resistance - especially for male sterilization in India
