African American adults are less likely to meet the recommended physical activity guidelines for aerobic and muscle-strengthening activity than Caucasian adults. The purpose of this study was to assess whether a text message intervention would increase physical activity in this population. This pilot study used a pre-/post-questionnaire non-randomized design. Participants in a faith-based weight loss competition who agreed to participate in the text messaging were assigned to the intervention group ( = 52). Participants who declined to participate in the intervention, but agreed to participate in the study, were assigned to the control group ( = 30). The text messages provided strategies for increasing physical activity and were based on constructs of the Health Belief Model and the Information-Motivation-Behavioral Skills Model. Chi square tests determined the intervention group participants increased exercise time by approximately eight percent ( = 0.03), while the control group's exercise time remained constant. The intervention group increased walking and running. The control group increased running. Most participants indicated that the health text messages were effective. The results of this pilot study suggest that text messaging may be an effective method for providing options for motivating individuals to increase physical activity.
与白人成年人相比，非裔美国成年人达到有氧运动和肌肉强化活动推荐身体活动指南的可能性较小。本研究的目的是评估短信干预是否会增加该人群的身体活动。这项试点研究采用了前后问卷调查的非随机设计。参加基于信仰的减肥竞赛且同意参与短信干预的参与者被分配到干预组（n = 52）。拒绝参与干预但同意参与研究的参与者被分配到对照组（n = 30）。短信提供了增加身体活动的策略，这些策略基于健康信念模型和信息-动机-行为技能模型的构建。卡方检验确定干预组参与者的运动时间增加了约8%（p = 0.03），而对照组的运动时间保持不变。干预组增加了步行和跑步。对照组增加了跑步。大多数参与者表示健康短信是有效的。这项试点研究的结果表明，短信可能是一种为激励个人增加身体活动提供选择的有效方法。
