目的：确定文化上是否适合诊所和社区。非裔美国女性2型糖尿病患者的干预将增加中等强度的身体活动（PA）。研究设计和方法：在这项随机对照试验中，200名40岁的非裔美国女性2型糖尿病患者被随机分为三个治疗组：诊所和社区（A组），仅诊所（B组），或最小干预（C组）。以诊所为基础的干预（A组和B组）包括每月4次与营养师的访问，营养师提供咨询，以提高PA和饮食摄入量，以适应基线做法和态度；以社区为基础的干预（A组）包括3次小组会议和12个月来自同伴咨询师的电话，旨在提供社会支持和加强行为改变目标；最小干预（C组）包括向参与者邮寄教育小册子。主要研究结果是在6个月和12个月时通过加速度计评估两组之间的PA水平的比较，加速度计在清醒时佩戴7天。结果：共有175名（88%）和167名（84%）参与者分别在6个月和12个月完成了PA评估。PA比较，整体组效应P值为0.014。A组与C组比较，PA的平均调整平均值的差异为44.1 kcal/day （95% CI 13.1-75.1, P = 0.0055）。B组与C组比较，平均调整平均值差33.1 kcal/d （95% Cl 3.3 ~ 62.8, P = 0.029）。干预对参与者来说是可以接受的：88%的人非常满意以临床为基础的咨询，以提高个人行为能力，86%的人表示同伴咨询师在项目中的作用是重要的。结论：干预与PA的适度增强有关，并且是参与者可以接受的。
OBJECTIVE- To determine whether a culturally appropriate clinic- and community-based. intervention for African-American women with type 2 diabetes will increase moderate-intensity physical activity (PA).RESEARCH DESIGN AND METHODS- in this randomized controlled trial conducted at seven practices in central North Carolina, 200 African-American women, :40 years of age with type 2 diabetes, were randomized to one of three treatment conditions: clinic and community (group A), clinic only (group B), or minimal intervention (group C). The clinic-based intervention (groups A and B) consisted of four monthly visits with a nutritionist who provided counseling to enhance PA and dietary intake that was tailored to baseline practices and attitudes, the community-based intervention (group A) consisted of three group sessions and 12 monthly phone calls from a peer counselor and was designed to provide social support and reinforce behavior change goals; and the minimal intervention (group C) consisted of educational pamphlets mailed to participants. The primary study outcome was the comparison of PA levels between groups assessed at 6 and 12 months by accelerometer, which was worn while awake for 7 days.RESULTS- Totals of 175 (88%) and 167 (84%) participants completed PA assessment at 6 and 12 months, respectively. For comparison of PA, the P value for overall group effect was 0.014. Comparing group A with C, the difference in the average adjusted mean for PA was 44.1 kcal/day (95% CI 13.1-75.1, P = 0.0055). Comparing group B with C, the difference in the average adjusted mean was 33.1 kcal/day (95% Cl 3.3-62.8, P = 0.029). The intervention was acceptable to participants: 88% were very satisfied with clinic-based counseling to enhance PA, and 86% indicated that the peer counselor's role in the program was important.CONCLUSIONS- The intervention was associated with a modest enhancement of PA and was acceptable to participants.
