African American women are at increased risk for CVD morbidity and mortality relative to white women. Physical inactivity and poor dietary habits are modifiable health behaviors shown to reduce CVD risk. Community health centers have the potential to reach large numbers of African Americans to modify their risk for CVD, yet few lifestyle counseling interventions have been conducted in this setting.
The HHER Lifestyle trial is a randomized controlled trial to compare the effects of a standard care intervention (provider counseling, nurse goal setting, and educational materials) to a comprehensive intervention (standard care intervention plus 12 months of telephone counseling and tailored print materials) on changes in physical activity and dietary fat consumption in financially disadvantaged African American women at 6 and 12 months. Secondary outcomes are body mass index, central adiposity, and total cholesterol. Potential mediators of outcome are self-efficacy for overcoming barriers, social support, and decisional balance.
African American women (N=266; 130 standard care, 136 comprehensive intervention) 35 years and older from nine clinics within two community health centers were enrolled. Most participants were overweight or obese with existing chronic health conditions.
The HHER Lifestyle trial is unique in that it targets financially disadvantaged African American women from community health centers, incorporates a standard care intervention into a routine clinical appointment, and includes a comprehensive process evaluation. The design will permit further research examining the added effect of regular telephone counseling and tailored print materials to a primary care provider and nurse intervention.
与白人女性相比,非裔美国女性患心血管疾病的发病率和死亡率更高。身体活动不足和不良的饮食习惯是可改变的健康行为,可以降低心血管疾病的风险。社区卫生中心有潜力接触到大量的非裔美国人,改变他们患心血管疾病的风险,但在这种环境下很少有生活方式咨询干预措施。
HHER 生活方式试验是一项随机对照试验,旨在比较标准护理干预(提供咨询、护士设定目标和教育材料)与综合干预(标准护理干预加 12 个月电话咨询和定制印刷材料)对经济困难的非裔美国女性在 6 个月和 12 个月时身体活动和膳食脂肪摄入量变化的影响。次要结果是体重指数、中心性肥胖和总胆固醇。结果的潜在中介因素是克服障碍的自我效能、社会支持和决策平衡。
来自两个社区卫生中心的九家诊所的年龄在 35 岁及以上的非裔美国女性(N=266;130 名标准护理,136 名综合干预)参与了该试验。大多数参与者超重或肥胖,并有现有的慢性健康状况。
HHER 生活方式试验是独特的,因为它针对的是来自社区卫生中心的经济困难的非裔美国女性,将标准护理干预纳入常规临床预约,并包括全面的过程评估。该设计将允许进一步研究,探讨定期电话咨询和定制印刷材料对初级保健提供者和护士干预的附加效果。
