Exposure variables
EARLY PREGNANCY
Community workers providing advice about ANC services, helping with early pregnancy registration, counselling on birth preparedness, and supporting ANC services during COVID-19 were treated as independent variables. Other covariates, such as state, age, education, religion, caste, family size, and return of migrant members during COVID-19, were included to understand the differentials. The return of a migrant member was considered a possible covariate as households with such members may have been left out by community health workers (CHWs) due to COVID-19, which may have impacted mothers or pregnant women in those households.
