Table 3. Physical Activity and Health-Related Characteristics by Cluster, Combined Baltimore-Seattle Region Sample.

	Cluster			Effect Sizes (Cohen's d)^d

Characteristics	Low Activity (n ≥ 1097)	Active Leisure (n ≥ 294)	Active Job (n ≥ 238)	Active Leisure vs. Low Activity	Active Leisure vs. Active Job	Active Job vs. Low Activity

Note. Due to missing data, n sizes ranged: Low Activity = 1097-1131; Active Leisure = 294-309; Active Job = 238-248. The Baltimore and Seattle-region samples were analyzed separately and ANOVA indicated a similar pattern of results to the combined sample.

Geometric means and 95% confidence intervals (in parentheses) reported.

Means and standard deviations (in parentheses) reported.

Self-rated health: 1 = poor; 5 = excellent.

Cohen's d effect sizes: 0.2 = small; 0.5 = medium; 0.8 = large (Cohen, 1988).
