Adjusted regression model results for mean triglycerides with clusters representing joint temporal dietary and physical activity patterns of US adults aged 20–65 y as drawn from the NHANES, 2003–20061

There were significant differences in mean triglycerides between Clusters 1 and 2, Clusters 1 and 4, and Clusters 2 and 3 in the unadjusted model at P < 0.05 (see Supplemental Table 4). *Significant difference: adjusted P < 0.05.
Multiple linear regression models were used and were adjusted for survey year, age group, sex, race/ethnicity, poverty to income ratio, BMI, energy misreporting, and total physical activity counts per day.
Values are mean ± SEM.
β represents the difference of mean triglycerides between 2 compared clusters. Least square means were used to calculate the differences in mean triglycerides.
