Context: COVID-19 response needs to be enlightened with representative data regarding the humoral response to the virus, and its relationship with the clinico-epidemiological profile of the general population. Aims: To estimate the titres of IgG antibodies against SARS-CoV-2 and study the factors associated with the same among the general population of the Pimpri Chinchwad Municipal Corporation area. Settings and Design: Population-based cross-sectional study was carried out among the general population aged 6 years and above in the Pimpri Chinchwad Municipal Corporation area. Methods and Material: A total of 10,082 individuals from 106 wards of the PCMC area were studied between June 16, 2021 and June 26, 2021. The survey form questionnaire included sociodemographic details, COVID-19 exposure history, symptoms, tests, and vaccination status. About 3 to 5 ml blood samples were collected from each subject. Testing of samples was done using ABBOTT CMIA, SARS-CoV-2 quant assay—sensitivity 92.7% and specificity 99.9%. Statistical Analysis Used: Frequency analysis was done for sociodemographic variables, and antibody titres. An appropriate test of association was applied to the association between antibody titres and the sociodemographic and clinical profile of participants. Results: Antibody titres were significantly higher in males, aged 45 years and above, participants of upper socioeconomic class, participants residing in elite areas, subjects with a history of COVID-like symptoms in the past, and those who were vaccinated. Conclusions: Anti-SARS-CoV-2 IgG antibodies titres were found to be significantly associated with age, sex, socioeconomic status, area of residence, vaccination status, and history of COVID symptoms.
