Sisters Healthy & Physically Empowered (SHAPE): Physical Activity Among African Americans

非裔美国妇女患心脏代谢疾病的风险增加，定期体育活动可以降低这种疾病的风险。不幸的是，他们也是身体活动最少的人口亚群之一。社区环境是进行体育活动干预的有吸引力的地方，因为它们在舒适的环境中接触到人们。没有一项试验调查在迎合非洲裔美国妇女的美容院进行身体活动干预，尽管这是一个环境， 妇女们经常参观一个强化核心文化价值的地方。这项试验将测试为期4个月的，文化敏感的社会生态干预，强调社会支持，在美容院进行，增加中度到剧烈的体力活动水平的非洲裔美国妇女相比，比较条件的影响。将在基线和干预后评估通过连续7天佩戴的Actigraph加速度计测量的中度至剧烈体力活动。还将评估体重、血压和选定的心理社会介质。年龄在18至60岁之间的健康参与者将从他们经常光顾的美容院和理发店招募。16家美容院（每家美容院25名女性）将被随机分配到体力活动干预或比较干预中。干预活动将在沙龙进行，并纳入非裔美国妇女的核心文化价值观。 它将提高社会支持，体育活动的行为技能，并在沙龙内创造一个规范的体育活动环境。比较干预将通过读书俱乐部关注生活肯定和个人成长。将使用2阶段分层线性模型分析结果。该试验将确定是否以文化为基础的干预措施，重点是在沙龙中提供的现有社交网络中的社会支持，可以增加非裔美国妇女的身体活动。这项研究将有助于第三代健康差距研究的证据基础，通过测试在社区环境中提供的文化敏感的身体活动干预。

African American women are at increased risk for cardiometabolic diseases ~ conditions for which risk is reduced by regular physical activity. Unfortunately, they are also one of the least physically active population subgroups. Community settings are attractive places to conduct physical activity interventions because they reach people in comfortable surroundings. No trial has investigated conducting a physical activity intervention in beauty salons that cater to African American women, although this is a setting in which women regularly visit and a place that reinforces core cultural values. This trial will test the effects of a 4- month, culturally-sensitive social ecological intervention emphasizing social support, conducted in beauty salons, for increasing moderate to vigorous physical activity level in African American women compared with a comparison condition. Moderate to vigorous physical activity, measured from Actigraph accelerometers worn over 7 consecutive days, will be assessed at baseline and post-intervention. Weight, blood pressure, and selected psychosocial mediators will also be assessed. Generally healthy participants between the ages of 18 and 60 years will be recruited from beauty salons and barbershops in which they frequent. 16 salons (25 women per salon) will be randomized into a physical activity intervention or comparison intervention. The intervention will be conducted in the salons and incorporate core cultural values of African American women. It will enhance social support, physical activity behavioral skills, and create a normative environment for physical activity within the salons. The comparison intervention will focus on life affirmation and personal growth through a book club. Results will be analyzed using 2-stage hierarchical linear modeling. The trial will determine if culturally grounded interventions, focusing on social support among existing social networks, delivered in salons, can increase physical activity in African American women. This study will contribute to the evidence base of third generation health disparities research by testing a culturally sensitive physical activity intervention delivered in a community setting.
