  1. Only individuals from the second cohort (N = 2681) were included in this multivariate mixed-effects logistic regression model because complete epidemiological information were only available for these individuals. In this model all fixed-effect variables were adjusted for clustering at different months of data collection (time of sampling), at the household level, and at the individual level, with the individual level nested within the household level
