For BMI and waist circumference, models were rerun eliminating time points where women indicated they were pregnant during that period. However, no notable differences were found
aMixed effects or generalized linear mixed models were used to adjust for the clustering effects of churches and to account for repeated measures over M2 and M3. All analyses were adjusted for the baseline measure of the outcome, age, marital status, employment and education
