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. P; Tests of linear trend across increasing PSR, ∑ω-3/∑ω-6, h/H, AI, TI, LI and TF 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 PSR, ∑ω-3/∑ω-6, h/H, AI, TI, LI and TF 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 (BMI ≥ 25), WC waist circumference, WHtR waist to height ratio, PSR polyunsaturated to saturated fatty acids ratio, ∑ω-3/∑ω-6; omega-3 to omega-6 fatty acids ratio, h/H hypo and hypercholesterolemic ratio, AI Atherogenicity index, TI Thrombogenic index, LI Dietary lipophilic index, TF Percentage of energy from total fat
