COVID-19 Inequality & Social Determinants of Health

How COVID-19 Disproportionately Affected the Poor

• Unequal access to healthcare – lack of insurance, hospitals, ICU facilities, diagnostic tests → late diagnosis, higher mortality
• Crowded living conditions – slums, overcrowded housing → social distancing impossible, increased transmission
• Nature of employment – informal sector, daily wage, manual labor → could not work from home, lost income during lockdowns
• Malnutrition and weak immunity – poor nutrition → severe infection, complications, death
• Digital divide – lack of smartphones, internet access → excluded from online education, work, health consultations

• Migrant workers' crisis – lost jobs, shelter, walked long distances → reflected poor social protection
• Global vaccine inequality – rich countries secured vaccines earlier → unequal protection
• Mental health impact – stress, anxiety, depression, uncertainty
• Gender dimension – increased domestic violence, unpaid care burden, job loss in informal sectors

Key Observations

• Literacy is lower among SC and ST populations compared to total population
• Female literacy is much lower in all groups, especially among SCs and STs
• Agricultural labour is significantly higher among SCs (40%) and STs (36%) vs total (27%)
• SC female agricultural labourers (51%) show highest dependency on manual labour

Social Determinants & Health Implications

• Low literacy → poor health awareness, reduced healthcare utilization, lack of empowerment
• Agricultural labour → low wages, seasonal unemployment, financial insecurity, occupational hazards
• Caste-based inequality → social exclusion, discrimination, lack of opportunities
• Health consequences → malnutrition, communicable diseases, maternal mortality, poor child health

Social Determinants at Play

• Poverty and low wages – low income, irregular wages, poor social security → hunger, poor nutrition
• Severe malnutrition – very low BMI → chronic undernutrition, poor immunity, susceptibility to disease
• Poor healthcare infrastructure – lack of hospitals, doctors, nurses → delayed treatment, preventable deaths
• Occupational and living conditions – overcrowded settlements, poor sanitation, unsafe housing → increased disease risk

• Lack of education and awareness – low literacy limits health awareness, nutrition knowledge, healthcare-seeking
• Social and economic marginalization – lack political voice, labor rights, social protection
• Food insecurity – irregular employment and low wages lead to starvation, poor diet quality

Definition

Social determinants of health are the social, economic, environmental, and political conditions in which people are born, grow, live, work, and age. These conditions influence health status, disease occurrence, quality of life, and life expectancy.

Major Social Determinants

• Income and poverty
• Education
• Occupation and working conditions
• Housing and environment
• Nutrition and food security
• Healthcare access
• Gender and social equality
• Social support and community networks

Importance in Public Health

• Explains why some populations remain healthier while others experience greater disease burden
• Health is not determined only by biology or medical care
• WHO emphasizes reducing health inequalities requires improving social conditions

Examples

• Poor sanitation → diarrheal diseases
• Low literacy → poor maternal health
• Poverty → malnutrition and TB

Why Lifestyle Alone Cannot Explain Health Inequality

• Lifestyle choices are socially shaped – influenced by income, education, environment, resource availability
• Poverty limits healthy living – healthy foods expensive, poor may depend on cheap processed foods
• Poor housing and environment – overcrowding, pollution, unsafe neighborhoods increase disease risk regardless of personal behavior
• Occupational risks – hazardous jobs, physically demanding labor, unstable employment

• Education and awareness – lower education reduces health literacy and understanding of disease prevention
• Chronic stress and mental health – financial insecurity, social exclusion contribute to hypertension, depression, heart disease
• Unequal healthcare access – delayed treatment, lack of insurance, inadequate facilities
