目的：Go Girls是一个基于教会的营养和身体活动计划，专为超重的非裔美国人(AA)青春期女性设计。研究方法和程序：10个以中等社会经济为主的教会被随机分为高强度(20-26节)或中等强度(6节)文化定制行为小组干预，为期6个月。每节课包括体验性的行为活动，类似于30分钟的体力活动，以及准备和品尝健康食品。在高强度组，女孩也接到了四到六个电话咨询电话。来自10个教堂的123名女孩完成了基线和6个月的测试后评估。主要结果是体重指数；次要结果包括腰围和臀围，通过生物阻抗估计的体脂百分比，血清胰岛素、血糖和血脂，以及6个月随访时的心血管健康状况。结果：在6个月的随访中，高强度组和中等强度组之间的净差值为0.5BMI单位。这一差异无统计学意义(p=0.20)。在二次结局方面，两组之间没有显著差异。然而，参加超过四分之三课程的高强度状态的女孩，与参加较少课程的高强度组女孩相比，体重指数和体脂百分比显著降低。1年的随访结果与6个月时的结果相同。讨论：我们得出的结论是，尽管在高发人群中有一些积极的发现，但干预在减少肥胖症方面并不有效。尽管结果为零，但参与者普遍对干预措施表示欢迎。未来的干预可能需要更大的剂量和更有条理的饮食改变计划。
Objective: Go Girls was a church-based nutrition and physical activity program designed for overweight African-American (AA) adolescent females.Research Methods and Procedures: Ten predominantly middle-socioeconomic churches were randomized to either a high-intensity (20 to 26 sessions) or moderate-intensity (six sessions) culturally tailored behavioral group intervention delivered over 6 months. Each session included an experiential behavioral activity, similar to 30 minutes of physical activity, and preparation and tasting of healthy foods. In the high-intensity group, girls also received four to six telephone counseling calls. From the 10 churches, 123 girls completed baseline and 6-month post-test assessments. The primary outcome was BMI; secondary outcomes included waist and hip circumferences, percentage body fat estimated by bioimpedance, serum insulin, glucose, and lipids, and cardiovascular fitness at 6-month follow-up. Selected measures were also collected at 1-year follow-up.Results: At 6-month follow-up, the net difference between the high- and moderate-intensity groups was 0.5 BMI units. This difference was not statistically significant (p = 0.20). There were no significant group differences in secondary outcomes. Girls in the high-intensity condition, however, who attended more than three-quarters of the sessions had significantly lower BMI and percentage body fat relative to girls in the high-intensity group who attended fewer sessions. Findings at 1-year follow-up mirrored those at 6 months.Discussion: We concluded that the intervention was not effective in reducing adiposity, although there were some positive findings among high attenders. Despite the null result, the intervention was generally well received by participants. Future interventions may require greater dose and a more structured dietary change program.
