南非黑人的慢性病发病率很高。很少有研究测试认知-行为健康促进干预措施，以减少南非的慢性病。我们在一项整群随机对照试验中测试了这种干预在青少年中的有效性。我们随机选择了17所配对学校中的9所，每对学校中的一所随机接受旨在鼓励健康相关行为的认知-行为健康促进干预，而另一所学校则随机接受艾滋病毒/性传播疾病风险降低干预作为对照。干预基于社会认知理论、计划行为理论和来自目标人群的定性数据。数据收集者对参与者的干预视而不见，在基线以及干预后3、6和12个月进行保密评估。主要结果是水果和蔬菜的摄入量和体力活动。参与者为1,057名六年级学习者(平均年龄=12.4岁)，96.7%的人在12个月的随访中保持不变。广义估计方程显示，在随访期间的平均情况下，健康促进干预参与者的比例高于艾滋病毒/性传播疾病对照参与者，符合每天5种水果蔬菜和体力活动指南的比例更高。干预还增加了促进健康的知识、态度和意图，但没有减少物质使用或物质使用的态度和意图。研究结果表明，基于理论的、与环境相适应的干预措施可能会增加撒哈拉以南非洲青少年的健康行为。
Rates of chronic diseases are high among Black South Africans. Few studies have tested cognitive-behavioral health-promotion interventions to reduce chronic diseases in South Africa. We tested the efficacy of such an intervention among adolescents in a cluster-randomized controlled trial. We randomly selected 9 of 17 matched-pairs of schools and randomized one school in each pair to the cognitive-behavioral health-promotion intervention designed to encourage health-related behaviors and the other to a HIV/STD risk-reduction intervention that served as the control. Interventions were based on social cognitive theory, the theory of planned behavior, and qualitative data from the target population. Data collectors, blind to participants’ intervention, administered confidential assessments at baseline and 3, 6, and 12 months post-intervention. Primary outcomes were fruit and vegetable consumption and physical activity. Participants were 1,057 grade 6 learners (mean age = 12.4 years), with 96.7% retained at 12-month follow-up. Generalized estimating equations revealed that averaged over the follow-ups, a greater percentage of health-promotion intervention participants than HIV/STD control participants met 5-a-Day fruit and vegetable and physical activity guidelines. The intervention also increased health-promotion knowledge, attitude, and intention, but did not decrease substance use or substance-use attitude and intention. The findings suggest that theory-based, contextually appropriate interventions may increase health behaviors among young adolescents in sub-Saharan Africa.
