Burden of Pneumonia and its Determinants in Faislabad, Pakistan : A Population-Based Epidemiological Analysis

Abstract

Pneumonia remains a leading cause of morbidity and mortality in low- and middle-income countries, with a substantial burden observed in urban and peri-urban populations of Faisalabad. This population-based epidemiological study investigates the prevalence, incidence, and key determinants of pneumonia among different age groups in Faisalabad, Pakistan. A cross-sectional design was employed using household survey data, hospital records, and demographic information collected through stratified random sampling. The study identifies socio-economic status, environmental exposure (such as air pollution and indoor smoke), vaccination coverage, nutritional status, and access to healthcare as major determinants influencing pneumonia risk. Statistical analyses, including multivariate logistic regression, were used to assess associations between risk factors and disease occurrence. Findings indicate a higher burden among children under five and the elderly, particularly in low-income communities with limited healthcare access. Seasonal variation and overcrowded living conditions further exacerbate disease transmission. The study underscores the urgent need for targeted public health interventions, improved immunization programs, awareness campaigns, and enhanced healthcare infrastructure to reduce pneumonia-related morbidity and mortality in Faisalabad. These findings provide evidence-based insights for policymakers and healthcare stakeholders to design effective prevention and control strategies.
