    Regular physical activity is important for health benefits among youth, but disparities exist. This paper describes disparities in physical activity participation and sedentary behaviors among youth in the United States, provides intervention implications, and offers recommendations for future research focused on reducing disparities related to levels of physical activity. Secondary analysis of national accelerometer data showed that achievement of recommended levels of physical activity ranged across subgroups from 2% to 61%. Mean hours per day spent in sedentary behavior ranged from 5.5 to 8.5. The largest disparities were by gender and age. An improved understanding of correlates may inform the design of interventions to increase physical activity in targeted subgroups. Additional theoretically based research is needed to elucidate which factors contributing to physical activity disparities are amenable to change via intervention. To eliminate health disparities, changes in policies that have an impact on physical activity may be necessary to promote physical activity among high-risk youth.

    BACKGROUND: Family and friend participation may provide culturally salient social support for weight loss in African American adults. METHODS: SHARE (Supporting Healthy Activity and eating Right Everyday) was a 2-year trial of a culturally specific weight loss program. African American women and men who enrolled alone (individual stratum, 63 index participants) or together with 1 or 2 family members or friends (family stratum, 130 index participants) were randomized, within strata, to high or low social support treatments; 90% were female. RESULTS: At 6 months, the family index participants lost approximately 5 to 6 kg; the individual index participants lost approximately 3 to 4 kg. The mean weight change was not different in high vs low social support in either stratum and generally not when high or low support treatments were compared across strata. The overall intention-to-treat mean weight change at 24 months was -2.4 kg (95% confidence interval, -3.3 kg to -1.5 kg). The family index participant weight loss was greater among the participants whose partners attended more personally tailored counseling sessions at 6 months in the high-support group and at 6, 12, and 24 months in the low-support group (all P < .05). Also, in the 6-month intention-to-treat analysis, the percentage of weight loss of the family index participants was greater if partners lost at least 5% vs less than 5% of their baseline weight (respectively, -6.1% vs -2.9% [P = .004], high support; and -6.1% vs -3.1% [P = .01], low support). CONCLUSIONS: Being assigned to participate with family members, friends, or other group members had no effect on weight change. Enrolling with others was associated with greater weight loss only when partners participated more and lost more weight. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00146081.
