P1: unadjusted; P2: adjusted for age (continuous); asset score (continuous); physical activity level (natural log transformed); dietary energy/kcal (continuous); woman education (categorical); husband education (categorical); occupation woman (categorical); occupation husband (categorical); marital status (categorical). In the multiple regression models, dummy variables were created for categorical covariates. TF; percentage of energy obtained from dietary fat. P; Test of linear trends across quintiles of SFA, PUFAs, ∑ω-3, and ∑ω-6 were calculated for the models assessing chance of overweight/obesity as measured by body mass index, waist circumference and waist circumference to height ratio. To analyze these linear trends, the median values of total SFA, PUFAs, ∑ω-3, and ∑ω-6 were imputed for each quintile and the new variables were treated as continuous variables. All tests statistics are considered significant for P < 0.05, OR Odds ratio, CI Confidence Interval, GO General obesity, WC waist circumference, WHtR waist to height ratio, SFA Saturated fatty acids, PUFA Polyunsaturated fatty acids, ∑ω-3; Summation of omega-3 polyunsaturated fatty acids, ∑ω-6; Summation of omega-6 polyunsaturated fatty acids
