Odds of obesity relative to normal weight status and covariate-adjusted regression model results for clusters representing joint temporal dietary and physical activity patterns of US adults aged 20–65 y as drawn from the NHANES, 2003–2006¹

Adjusted models2	n, %	OR3 compared with Cluster 2	95% CI	Adjusted P value	OR3 compared with Cluster 3	95% CI	Adjusted P value	OR3 compared with Cluster 4	95% CI	Adjusted P value

¹There were significant differences in OR of obesity to normal weight among all clusters except Clusters 2 and 4 in the unadjusted model at P < 0.05 (see Supplemental Table 3). *Significant difference: adjusted P < 0.05.

²Multiple logistic regression models were used and were adjusted for survey year, age group, sex, race/ethnicity, poverty to income ratio, energy misreporting, and total physical activity counts per day.

³OR of obesity to normal weight between 2 compared clusters. Obesity was classified as BMI ≥ 30 kg/m² (95).
