CHD are structural cardiac anomalies which are a leading cause of childhood mortality and morbidity in India and have multifactorial aetiology. Compromised socioeconomic status augments several environmental stressors and is shown to have a positive association with CHD in offspring. The presented study is an institution-based case-control study to explore the same with CHD as the primary outcome.

A total of 2064 paediatric patients (1760 CHD cases and 304 controls with structurally normal hearts) were analysed. Demographic and socioeconomic status parameters were recorded using the Kuppuswamy scale. Statistical associations were examined using chi-square tests and odds ratios.

Majority of all patients belonged to the upper-lower class. No significant association was found between socioeconomic status and CHD (p = 0.18). However, rural residence was significantly associated with a higher risk of CHD (χ2 = 16.09, p = 0.0011; OR vs. urban = 1.59). A significant association was found between maternal education and CHD prevalence (χ2 = 20.9, p = 0.0001), with uneducated mothers having higher odds of children with CHD. Joint family structure also showed higher odds of having a child with CHD (OR = 1.75, p < 0.001).

While socioeconomic status alone was not significantly associated with CHD in this cohort—likely due to universal free care at our institute—maternal education, rural residence and family structure emerged as critical determinants. These findings highlight the need for targeted public health initiatives focusing on maternal literacy, rural healthcare access, and awareness programmes to improve early CHD diagnosis and outcomes. Further population-based research is needed to elucidate socioeconomic status-CHD associations at a broader level.
