Multivariable logistic regression model with significant variables associated with the presence of obesity

Obesity	OR (95% CI)	p
Age (years)	1.0 (1.0–1.0)	0.012
Have some first-degree relative with overweight or obesity	6.2 (3.6–10.7)	<0.001
Snacking
Almost never or never	Reference
Occasionally	0.7 (0.4–1.3)	0.264
Usually	2.1 (1.1–3.9)	0.019
Wine or beer consumption
<1 time per week	Reference
1–3 times per week	0.7 (0.3–1.3)	0.236
4–6 times per week	0.5 (0.2–1.2)	0.123
At least once per day	2.0 (1.2–3.6)	0.016
Chi-squared goodness of fit		0.059
Area under the ROC curve	0.8 (0.8–0.9)	<0.001

The group with normal weight was used as reference. The model was adjusted for the following confounding elements: age, sex, first-degree relative with overweight or obesity, sitting time, moderate and intense physical activity, sleeping time, snacking habit, and fish, red meat, and alcohol consumption. OR, odds ratio; CI, confidence interval; ROC, receiver operating characteristic.
