Background and aim This study explored the association between BMI and COVID-19 positive status in a tertiary care hospital from New Delhi. Methods Three hundred and seventy nine adult patients who presented to COVID-19 screening outpatient department of the hospital were interviewed over the phone regarding their body weight and height. The COVID-19 RT-PCR report of the patients was extracted from the hospital information system. Results The mean BMI and the prevalence of obesity was observed to be higher in individuals who were detected to be COVID-19 RT-PCR positive as compared to those who were negative. With every one-unit increment in BMI above 23 kg/m 2 , the odds of being COVID-19 positive increased by 1.8 times among these patients. Conclusion The findings suggest a dose-response association between BMI and the odds of COVID-19 infection in individuals with excess weight.

Background Preventive practices are the mainstay to mitigate the spread of the COVID-19 pandemic. We tried to assess the self-reported adherence of our participants to the already known preventive practices. Furthermore, we tried to determine whether the non-compliance to specific preventive practices was associated with the acquisition of the infection or not. Methods We enrolled 379 healthcare workers, hospital staff, and their family members who were tested for COVID-19 by reverse transcription-polymerase chain reaction (RT-PCR) in an outpatient clinic. Socio-demography and the infection prevention practices of the individuals were recorded in a preformed questionnaire. Statistical analysis was performed to find out the statistical association between these factors and the RT-PCR results. Adjusted and unadjusted odds ratios were determined to find out the degree of protection provided by each of the preventive practices concerning the development of the disease. Results Social distancing (p<0.001), hand hygiene (p<0.001), ensuring N-95 mask fit check (p<0.001), and the use of alternative medications (p=0.002) were found to be protective. Resident doctors were at a lower risk of developing the disease as compared to the other healthcare workers (odds ratio: 0.39). Conclusion The failure to practice the already known preventive practices is probably one of the most important factors in the progression of the COVID-19 pandemic. Adherence to these practices is the intervention of choice to reduce disease transmission in the current scenario.
