肥胖和超重是重要的临床和公共卫生问题，由于缺乏运动和不健康的饮食，这些问题不成比例地影响非洲裔美国人。我们比较了替代行为干预对肥胖相关健康行为的影响。我们进行了一项比较有效的教育试验，以社区为基础的样本530名成年非裔美国人。结果变量是体力活动（PA）和水果和蔬菜的摄入量。在基线和干预后1个月对癌症和心血管疾病（CVD）（综合，INT）或仅CVD（疾病特异性）的共同风险因素进行评估。从基线（47.4%）到随访（52.4%），符合PA指南的参与者比例显著增加（P = 0.005）。在进行分层分析，以检查教育和干预组分配之间的相互作用，这种影响是最明显的参与者中，高中教育，并被随机分配到INT（OR = 2.28，95% CI = 1.04，5.00，P = 0.04）。完成干预与符合PA指南的几率为1.78相关（95% CI = 1.02，3.10，P = 0.04）。关于慢性病危险因素的教育和基于证据的健康行为改变策略可能有助于解决非裔美国人与肥胖相关的行为。
Obesity and excess weight are significant clinical and public health issues that disproportionately affect African Americans because of physical inactivity and unhealthy eating. We compared the effects of alternate behavioral interventions on obesity-related health behaviors. We conducted a comparative effectiveness education trial in a community-based sample of 530 adult African Americans. Outcomes variables were physical activity (PA) and fruit and vegetable intake. Outcomes were evaluated at baseline and 1-month following interventions about shared risk factors for cancer and cardiovascular disease (CVD) (integrated, INT) or CVD only (disease-specific). Significant increases were found in the proportion of participants who met PA guidelines from baseline (47.4%) to follow-up (52.4%) (P = 0.005). In the stratified analysis that were conducted to examine interaction between education and intervention group assignment, this effect was most apparent among participants who had high school education and were randomized to INT (OR = 2.28, 95% CI = 1.04, 5.00, P = 0.04). Completing the intervention was associated with a 1.78 odds of meeting PA guidelines (95% CI = 1.02, 3.10, P = 0.04). Education about risk factors for chronic disease and evidence-based strategies for health behavior change may be useful for addressing obesity-related behaviors among African Americans.
