Urban Slum Health

Urban Slums - Defining the Depths

• UN-HABITAT Definition: A household lacking one or more:
  • Durable housing (permanent, protects from extreme climate).
  • Sufficient living area (≤ 3 people/room).
  • Access to improved water (safe, affordable, sufficient).
  • Access to improved sanitation (private or shared, hygienic).
  • Secure tenure (protection against forced eviction).
• Census of India (2011) Definition:
  • Notified, Recognized, or Identified.
  • Identified: Area with ≥ 300 population or 60-70 households; poorly built, congested, unhygienic, lacking basic amenities.
• Key Characteristics: Overcrowding, poor sanitation, unsafe water, insecure tenure, social exclusion.

⭐ As per Census 2011, 17.4% of urban Indian households lived in slums, totaling 65.49 million people.

Slum Diseases - The Health Maze

• Key Drivers: Overcrowding, poor sanitation, unsafe water, inadequate waste disposal.
• Disease Spectrum:
  • Communicable Diseases (CDs):
    • Water-borne: Diarrhea, Cholera, Typhoid, Hepatitis A/E.
    • Vector-borne: Malaria, Dengue, Chikungunya, Filariasis.
    • Air-borne: Tuberculosis (TB) (↑ risk), Acute Respiratory Infections (ARI).
  • Non-Communicable Diseases (NCDs):
    • Growing burden: Hypertension, Diabetes.
    • Chronic respiratory diseases (e.g., asthma from indoor pollution).
  • Maternal & Child Health (MCH) Issues:
    • High IMR & MMR.
    • Malnutrition (PEM, anemia) in women & children.
    • Suboptimal immunization.
  • Other Prevalent Conditions:
    • Skin infections (scabies, fungal), worm infestations.
    • Mental health disorders.

⭐ Slums often face a "triple burden" of disease: communicable diseases, non-communicable diseases, and social/mental health issues including injuries.

Slum Determinants - Unpacking the Causes

• Environmental Factors:
  • Overcrowding: ↑ disease transmission.
  • Poor WASH: Unsafe water, inadequate sanitation (e.g., open defecation), poor hygiene.
  • Pollution (air, water, noise); vector breeding.
  • Deficient waste & sewage disposal.
• Socio-Economic Factors:
  • Poverty & Unemployment: Limits access to essentials (food, housing, healthcare).
  • Low Literacy: Impacts health awareness & practices.
  • Social Exclusion, Stressors (e.g., migration, violence).
• Health System & Service Delivery:
  • Accessibility Barriers: Geographic, financial, social.
  • Availability Issues: Shortage of facilities, staff, medicines.
  • Poor Quality Care & Low health-seeking.

⭐ Slums face a "triple burden" of disease: communicable diseases, non-communicable diseases (NCDs), and injuries/violence.

Slum Solutions - Programs & Action

• National Urban Health Mission (NUHM): Launched 2013.
  • Focus: Urban poor, especially slum dwellers & other vulnerable groups like homeless, rag-pickers.
  • U-PHC: 1 per 50,000-60,000 pop.
  • U-CHC: FRU for 4-5 U-PHCs.
  • ASHA (USHA): 1 per 1000-2500 pop. or 200-500 households.
  • ANM: 1 per 10,000 pop.
  • Mahila Arogya Samiti (MAS): Community action (50-100 households).
• Key NUHM Strategies:
  • Strengthening existing health infrastructure.
  • Outreach services & mobile medical units.
  • Public-Private Partnerships (PPP).
  • Inter-sectoral convergence (WASH, nutrition).
  • BCC/IEC for health awareness.
• Convergence: Key schemes like JSSK, JSY benefits; ICDS; Swachh Bharat Abhiyan.

⭐ NUHM has a specific focus on the urban poor, including slum dwellers, by providing ASHA coverage of 1 per 1000-2500 population.

High‑Yield Points - ⚡ Biggest Takeaways

• Slums: Defined by overcrowding, substandard housing, and inadequate basic services.
• Predominance of communicable diseases (TB, diarrhea, ARI) and severe malnutrition.
• Rising trend of non-communicable diseases like hypertension and diabetes.
• Children <5 years and pregnant women are highly vulnerable populations.
• National Urban Health Mission (NUHM) is the key program for urban slum health.
• Major determinants: Poor sanitation, unsafe water, and limited healthcare access.
• Health indicators (e.g., IMR, U5MR) often significantly worse than urban averages_._
