The present review examines efficacious psycho-behavioral interventions in preventing weight gains or reducing weight among US multiethnic and minority adults as few studies were conducted to review such interventions to date.
Data were examined from 24 controlled intervention studies, representing 23 programs and involving 13,326 adults. Studies were identified through manual and online search of databases that include MEDLINE, Academic Search Premier, ERIC, PsycARTICLES, SPORTDiscus, and CINAHL Plus.
Whereas one-component (n=5, d=0.08, 90% CI=-0.04, 0.35) and two-component interventions (n=13, d=0.22, 90% CI=0.05, 0.40) showed a low mean effect size, three-component interventions (n=6, d=0.52, 90% CI=0.39, 0.65) showed a moderate effect size. Interventions conducted in individual sessions (n=15, d=0.40, 90% CI=0.24, 0.56) showed a higher mean effect size than group interventions (n=9, d=0.08, 90% CI=-0.04, 0.30) although the confidence intervals overlapped.
The study results indicate that future obesity prevention interventions targeting multiethnic and minority adults might benefit from incorporating individual sessions, family involvement, and problem solving strategies into multi-component programs that focus on lifestyle changes.
由于目前针对美国多民族及少数族裔成年人预防体重增加或减轻体重的有效心理行为干预措施的研究较少，本综述对相关研究进行了考察。
对24项对照干预研究的数据进行了分析，这些研究代表了23个项目，涉及13326名成年人。通过手动和在线搜索数据库来识别研究，这些数据库包括MEDLINE、学术搜索全文数据库、教育资源信息中心数据库、心理学文摘数据库、体育与运动科学全文数据库和护理学与健康领域数据库。
单成分干预（n = 5，d = 0.08，90%置信区间=-0.04，0.35）和双成分干预（n = 13，d = 0.22，90%置信区间=0.05，0.40）的平均效应量较低，而三成分干预（n = 6，d = 0.52，90%置信区间=0.
