African-American college students are less likely to meet recommended physical activity guidelines to promote health, and are at risk of overweight, obesity, and elevated blood pressure. Text messaging is an emerging international technology shown to engage college students, promote physical activity, and reduce health risks.
To determine the feasibility of using text messaging to promote physical activity among African-American college students enrolled in a unique course focusing on lifestyle behaviors for a healthy heart.
A purposive sample of 11 (n=4 male, n=7 female) African-American college students aged 18-25 years with cell phones capable of receiving messages was used in this study.
A three-week text-message protocol was piloted using web-based software to evaluate feasibility with post-hoc grouping of participants into responders and non responders. Descriptive statistics and Mann-Whitney U-tests were used to analyze group differences.
There was an attrition rate of nearly 91%. Observed engagement was 50% among responders with compliance at 44.44%. Observed engagement and compliance rates were less than 2% among nonresponders. There were no statistically significant differences in underlying variable distributions between groups. Of practical importance, it was noted that prior to texting responder means were higher for walking physical activity, and lower for body mass index, while nonresponders had higher means for vigorous physical activity.
The literature review indicated that text messaging is a cost-effective technology that can be incorporated into health education courses on HBCU campuses, but this project suggested semester timing is pivotal to feasibility. Implications largely address tailoring text messages to maintain engagement and evaluating the effect of text messages on physical activity level, body mass index, and blood pressure.
非裔美国大学生不太可能达到促进健康的推荐身体活动指南要求，面临超重、肥胖和血压升高的风险。短信是一项新兴的国际技术，已显示出能吸引大学生、促进身体活动并降低健康风险。
确定使用短信促进参加一门专注于健康心脏生活方式行为的独特课程的非裔美国大学生进行身体活动的可行性。
本研究采用了一个有目的的样本，选取了11名（4名男性，7名女性）年龄在18 - 25岁、拥有能接收短信手机的非裔美国大学生。
使用基于网络的软件试行一项为期三周的短信协议，通过事后将参与者分为响应者和非响应者来评估可行性。使用描述性统计和曼 - 惠特尼U检验分析组间差异。
损耗率近91%。响应者的观察参与率为50%，依从率为44.44%。非响应者的观察参与率和依从率均低于2%。两组之间潜在变量分布无统计学显著差异。实际重要的是，注意到在发送短信之前，响应者在步行身体活动方面的均值较高，而体重指数较低，而非响应者在剧烈身体活动方面的均值较高。
文献综述表明，短信是一种具有成本效益的技术，可纳入历史上黑人学院和大学（HBCU）校园的健康教育课程，但该项目表明学期时间安排对可行性至关重要。其影响主要涉及定制短信以保持参与度，以及评估短信对身体活动水平、体重指数和血压的影响。
