This study assessed the effects of the Black Churches United for Better Health project on increasing fruit and vegetable consumption among rural African American church members in North Carolina.
Ten counties comprising 50 churches were pair matched and randomly assigned to either intervention or delayed intervention (no program until after the follow-up survey) conditions. A multicomponent intervention was conducted over approximately 20 months. A total of 2519 adults (77.3% response rate) completed both the baseline and 2-year follow-up interviews.
The 2 study groups consumed similar amounts of fruits and vegetables at baseline. AT the 2-year follow-up, the intervention group consumed 0.85 (SE = 0.12) servings more than the delayed intervention group (P < .0001). The largest increases were observed among people 66 years or older (1 serving), those with education beyond high school (0.92 servings), those widowed or divorced (0.96 servings), and those attending church frequently (1.3 servings). The last improvement occurred among those aged 18 to 37 years and those who were single.
The project was a successful model for achieving dietary change among rural African Americans.
本研究评估了“黑人教会联合促进健康”项目对北卡罗来纳州农村非裔美国教会成员增加水果和蔬菜摄入量的影响。
将包含50个教会的10个县进行配对匹配，并随机分配到干预组或延迟干预组（随访调查后才实施项目）。在大约20个月的时间里进行了多组分干预。共有2519名成年人（应答率为77.3%）完成了基线和2年随访访谈。
两个研究组在基线时摄入的水果和蔬菜量相似。在2年随访时，干预组比延迟干预组多摄入0.85份（标准误=0.12）（P<0.0001）。在66岁及以上人群（多摄入1份）、高中以上学历人群（多摄入0.92份）、丧偶或离异人群（多摄入0.96份）以及经常去教堂的人群（多摄入1.3份）中观察到的增加量最大。最后改善的是18至37岁人群和单身人群。
该项目是实现农村非裔美国人饮食改变的成功模式。
