Prevalence ratio of overweight/obesity and central obesity by cluster
| Model 1* | Model 2* | |||
|---|---|---|---|---|
| Overweight/obesity (n=1182) | Central obesity (n=1183) | Overweight/obesity (n=1132) | Central obesity (n=1133) | |
| Cluster 1 | 1.26 (1.10, 1.45) | 1.27 (0.81, 1.98) | 1.12 (1.11, 1.13) | 1.16 (0.92, 1.45) |
| Cluster 2 | 1.15 (1.03, 1.28) | 0.88 (0.81, 0.95) | 1.07 (1.02, 1.12) | 0.73 (0.69, 0.76) |
| Cluster 3 | 1.35 (1.27, 1.42) | 1.47 (1.45, 1.50) | 1.31 (1.31, 1.31) | 1.40 (1.33, 1.47) |
| Cluster 4 | [Reference] | [Reference] | [Reference] | [Reference] |
Cluster 1-higher screen time and poorer diet; Cluster 2-lower activity and longer sleepers; Cluster 3-active and shorter sleepers; and Cluster 4-healthiest. Overweight and obesity defined as age- and sex-adjusted body mass index percentiles were 85th-95th and > 95th, respectively, according to the Centers for Disease Control (CDC) standards. Central obesity was defined by 90th percentile according to the Third National Health and Nutrition Examination Survey (NHANES III)
* Prevalence ratio from generalized models using a Poisson distribution with a log link and robust error variance. Model 1: Region and school were handled as random effects to account for the clustered study design. Model 2 was additionally adjusted for fasting status, maturation stage, migrant background, and parental education level were included as fixed-effect variables. Significant differences (p < 0.05) are presented in bold
