Women	0.033	0.018–0.049	<0.0001	0.014	0.007–0.020	<0.0001
Model 2: % energy intake from fat (10% per day increase)
		Weight (kg) 3		BMI (kg/m2)
	Coefficient	95% CI	p value	Coefficient	95% CI	p value
Average	0.092	0.051–0.133	<0.0001	0.038	0.022–0.054	<0.0001

Model 3: High-fat diet (energy intake from fat > 30%) 5
Overweight and obesity	RR 6	95% CI	p value
Average	1.13	1.04–1.23	0.003

¹ Adjusted for age, sex, physical activity tertiles, income tertiles, residency, smoking status, drinking status, and survey year. ² Additionally adjusted for total nonfat energy. ³ Additionally adjusted for height. ⁴ 95% confidence interval (CI). ⁵ Additionally adjusted for total fat intake. ⁶ Relative risk (RR). Model 1: Association of fat intake (10 g/d increase) with body weight and Body Mass Index (BMI). Random-effects linear regression models were used. Model 2: Association of percentage of energy intake from fat (10% per day increase) with body weight and BMI. Random-effects linear regression models were used. Model 3: Association between a high-fat diet (energy intake from fat > 30%) and the risk of overweight and obesity. Random-effects logistic regression models were used.
