• Demographic Definition of Infant Mortality Rate (IMR):
• Formula:

$$\text{IMR} = \frac{\text{Number of infant deaths under 1 year of age in a given year}}{\text{Total number of live births in the same year}} \times 1,000$$

• Key Parameters:
• Numerator: Deaths occurring before the first birthday ($\lt 365\text{ days}$). Deaths before 28 days are neonatal; 28 to 365 days are post-neonatal.
• Denominator: Standardized per 1,000 live births.
• Contrast: Maternal Mortality Ratio (MMR) is expressed per $100,000$ live births.
• Conclusion: The occurrence of infant deaths for every 1,000 live births (Option 1).

Correct option: (1) The occurrence of infant deaths for every 1,000 live births.

• Stages of Grief and Bereavement (Kübler-Ross Model):
• Elisabeth Kübler-Ross formulated the seminal 5-stage framework of coping with death and grief:

• Denial (D): Defense mechanism characterized by shock, numbness, and refusal to acknowledge the loss ('This cannot be happening').
• Anger and Guilt (B): Emotional eruption directed at self, doctors, destiny, or deceased ('Why did this happen? It is unfair').
• (Bargaining): Attempting to negotiate postponement of reality.
• Depression and Loneliness (C): Realization of irrevocable loss leading to intense sadness, social withdrawal, and mourning.
• Acceptance and Adjustment (A): Coming to terms with reality, emotional stabilization, and reinvestment in life.
  • Correct Sequence: (D) $\rightarrow$ (B) $\rightarrow$ (C) $\rightarrow$ (A).

• Conclusion: (D), (B), (C), (A) (Option 2).

Correct option: (2) (D), (B), (C), (A)

• Psychological Dynamics of Midlife Crisis:
• Concept Origin (Elliott Jaques, Daniel Levinson):
• Typically occurs in middle adulthood (ages 40 to 55).
• Sparked by the psychological realization of finite lifespan ('time left to live' rather than 'time since birth'), bodily aging, and shifts in family/career roles.
• Key Characteristics:
• Intense reassessment, introspection, and questioning of past life choices, career accomplishments, marital fulfillment, and unrealized aspirations.
• Frequently accompanied by emotional turbulence and restructuring of life priorities.
• Contradicts notions of passive stability, complete contentment, or maintaining the status quo.
• Conclusion: Period of reassessment and questioning of life choices and goals (Option 3).

Correct option: (3) Period of reassessment and questioning of life choices and goals
