Infant Mortality Metrics - Counting Tiny Lives

  • Infant Mortality Rate (IMR): Deaths of infants <1 year per 1000 live births annually.
    • $IMR = (\text{Number of infant deaths <1 year} / \text{Total live births in a year}) * \textbf{1000}$
  • Neonatal Mortality Rate (NMR): Deaths of infants <28 days per 1000 live births.
  • Perinatal Mortality Rate (PNMR): Stillbirths (≥28 weeks gestation) + early neonatal deaths (<7 days) per 1000 total births.

⭐ India's current IMR is approx. 28 per 1000 live births (latest SRS data).

Neonatal Mortality Causes - First Month Foes

Neonatal period = first 28 days of life. Key causes:

  • Prematurity (<37 weeks) & Low Birth Weight (LBW <2.5kg)
  • Birth Asphyxia & Hypoxia (intrapartum-related)
  • Neonatal Infections:
    • Sepsis
    • Pneumonia
    • Meningitis
    • 📌 Remember: Infections like Sepsis, Pneumonia, Meningitis (SPM) are major threats.
  • Congenital Anomalies (e.g., cardiac, neural tube defects)

Leading Causes in India (approx. %):

Leading Cause (India)Approx. %
Prematurity & LBW35%
Birth Asphyxia & Trauma20%
Neonatal Infections16%
Congenital Anomalies9%

⭐ Prematurity and LBW are the leading causes of neonatal mortality in India.

Post-Neonatal Mortality Causes - Later Infant Threats

Key threats for infants aged 1-12 months:

  • Infections: Major killers.
    • Diarrheal Diseases
      • Leads to dehydration; ORS is vital.
    • Acute Respiratory Infections (ARIs) Factors affecting child morbidity
      • Pneumonia is a leading cause of death.
  • Malnutrition:
    • Often coexists with and worsens infections; Protein-Energy Malnutrition (PEM) is significant.
  • Accidents & Injuries:
    • Includes drowning, falls, burns, poisoning.
  • Congenital Anomalies (Persistent):
    • Structural/functional defects from birth (e.g., cardiac).

⭐ Pneumonia and diarrhea are major killers in the post-neonatal period.

Infant Mortality Risk Factors - Underlying Dangers

  • Maternal Factors:
    • Age extremes: <18 or >35 years
    • Low maternal education level
    • Maternal malnutrition (e.g., anemia, low BMI)
    • Inadequate or absent Antenatal Care (ANC)
  • Socio-economic & Environmental Factors:
    • Poverty, overcrowding
    • Poor sanitation, unsafe water supply
    • Indoor/outdoor air pollution
  • Healthcare Access & Quality:
    • Limited access to skilled birth attendants & emergency obstetric care
    • Poor quality of postnatal care

⭐ Lack of Antenatal Care (ANC) significantly increases risk of infant mortality.

Prevention Strategies - Shielding Our Future

A vital three-pronged approach: Antenatal, Intranatal, Postnatal care. Continuum of care for maternal and newborn health

  • Antenatal Care (ANC):
    • Early registration, min. 4 ANC visits.
    • Interventions: IFA, TT immunization, nutrition, danger sign awareness.
  • Intranatal Care:
    • Institutional delivery with Skilled Birth Attendance (SBA).
    • 📌 '5 Cleans': Clean hands, surface, cord tie, blade, cord stump.
    • Safe delivery.
  • Postnatal Care (PNC):
    • Essential Newborn Care (ENBC): Warmth, airway, cord care, Vit K.
    • Exclusive breastfeeding (6 months), full immunization.
    • Home-Based Newborn Care (HBNC) by ASHA. Key Initiatives: IMNCI, JSSK, RBSK.

⭐ IMNCI strategy: integrated management of common childhood illnesses to reduce mortality.

High‑Yield Points - ⚡ Biggest Takeaways

  • IMR: Deaths of infants <1 year per 1000 live births; neonatal mortality (first 28 days) is its largest component.
  • Top causes: Prematurity/LBW, birth asphyxia/trauma, neonatal sepsis/pneumonia, congenital anomalies, diarrhea.
  • Key interventions: Quality ANC, skilled birth attendance, exclusive breastfeeding (first 6 months), full immunization.
  • Kangaroo Mother Care (KMC) significantly improves survival in LBW infants.
  • IMNCI strategy provides an integrated approach to child survival.
  • National programs like JSSK aim to eliminate preventable infant deaths.
