This study tested the initial efficacy of implementing a physical activity (PA) behavior change intervention for midlife African American (AA) men.
Intervention components were based on information gathered during formative research preceding the intervention. Eligible participants were underactive AA men ages 45-66 years. In a quasi-experimental pre-post design, participants attended 90-min program sessions twice weekly for 8 weeks. Session topics specific to PA included overcoming barriers, gaining social support, setting goals, tracking progress and integrating into one's lifestyle. Participants were assigned to teams to facilitate group discussion, problem solving, accountability and camaraderie.
25 AA men (mean age = 54.7 ± 4.8 years) completed the intervention. After 8 weeks, significant (P < 0.05) positive changes were observed for moderate to vigorous-intensity PA (+7.3 hour week(-1)) and overall PA (+9.4 hour week(-1)), self-efficacy for PA (+12%), social support for PA from family (+28%) and friends (+53%), self-regulation for planning (+33%) and goal setting (+48%) and each fitness component (+9 to +144%). Based on a post-intervention satisfaction survey, participants rated the program very positively.
These positive results attest to the feasibility of successfully engaging midlife AA men in a tailored PA behavior change program.
本研究旨在测试针对中年非裔美国男性(AA)实施体力活动(PA)行为改变干预措施的初步效果。
干预措施的组成部分基于干预措施之前的形成性研究中收集的信息。符合条件的参与者是活动量不足的 AA 男性,年龄在 45-66 岁之间。在准实验性的预-后设计中,参与者每周两次参加 90 分钟的课程,共 8 周。与 PA 相关的特定课程主题包括克服障碍、获得社会支持、设定目标、跟踪进度并将其融入生活方式。参与者被分配到团队中,以促进小组讨论、解决问题、问责制和友谊。
25 名 AA 男性(平均年龄=54.7±4.8 岁)完成了干预。8 周后,观察到中度到剧烈强度 PA(+7.3 小时/周)和总体 PA(+9.4 小时/周)、PA 自我效能感(+12%)、来自家庭的 PA 社会支持(+28%)和朋友(+53%)、PA 计划自我调节(+33%)和目标设定(+48%)以及每个健身组成部分(+9 到+144%)均有显著(P<0.05)的正向变化。基于干预后的满意度调查,参与者对该计划给予了高度评价。
这些积极的结果证明了成功吸引中年 AA 男性参与量身定制的 PA 行为改变计划的可行性。
