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

非裔美国女性患心脏代谢性疾病的风险增加--这种疾病的风险可以通过定期的体力活动来降低。不幸的是，他们也是体力活动最少的人口亚群之一。社区环境是进行体力活动干预的有吸引力的地方，因为它们能在舒适的环境中接触到人们。还没有试验调查在迎合非裔美国女性的美容院进行身体活动干预的情况，尽管这是一个 妇女经常光顾，也是一个强化核心文化价值观的地方。这项试验将测试在美容院进行的为期4个月的、对文化敏感的社会生态干预的效果，该干预强调社会支持，与对照条件相比，提高非裔美国女性的中等到剧烈的身体活动水平。通过连续佩戴7天以上的Actigraph加速计测量中等到剧烈的体力活动，将在基线和干预后进行评估。体重、血压和选定的心理社会介体也将被评估。一般来说，年龄在18岁到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个沙龙(每个沙龙25名女性)将被随机分为体力活动干预或对照干预。干预将在沙龙进行，并纳入非裔美国女性的核心文化价值观。 它将增强社会支持、身体活动行为技能，并在沙龙内创造一个规范的身体活动环境。比较干预将通过读书俱乐部关注生活肯定和个人成长。结果将使用两阶段分层线性建模进行分析。这项试验将确定以文化为基础的干预措施，重点是在沙龙提供的现有社交网络中的社会支持，是否可以增加非裔美国女性的身体活动。这项研究将通过测试在社区环境中提供的对文化敏感的体力活动干预，为第三代健康差异研究的证据基础做出贡献。

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.
