Research has consistently shown the benefits of regular physical activity (PA) for women living with HIV and AIDS (WLWHA). This study is a pilot, randomised controlled crossover trial, reporting the effects of a contextualised PA intervention amongst a sample of 21 HIV positive Xhosa-speaking women of low socioeconomic status (SES). The study determined total moderate-to-vigorous PA (TMVPA) as measured subjectively by the Global Physical Activity Questionnaire (GPAQ), total weekly steps (TWS) as measured by a pedometer, and self-efficacy for PA as measured by the Physical Exercise Self-efficacy scale (PESES). Multivariate analysis of covariance (MANCOVA) was used to compute the impact of the intervention on TMVPA, TWS, and self-efficacy for PA from baseline to six weeks, and baseline to 12 weeks post-intervention controlling for pre-test differences in TMVPA. Results showed that participants exposed to the intervention had significant increases in PA as measured by TMVPA (p = .027), TWS (p = .032), as well as exercise self-efficacy (p = .000) from pre-test to 6 weeks. Insignificant findings were reported for all three variables when measured from baseline to 12 weeks. In conclusion, the findings of the pilot study suggest that the intervention was effective in producing significant increases in PA in a sample of PLWHA of low SES over six weeks. Careful consideration of behavioural constructs, such as self-efficacy, can help WLWHA of low SES to adopt regular PA as a complementary therapy for managing their health.
研究一直表明，定期进行体育活动（PA）对感染艾滋病毒和艾滋病的女性（WLWHA）有益。本研究是一项试点随机对照交叉试验，报告了针对21名社会经济地位低下（SES）、讲科萨语的艾滋病毒阳性女性样本进行的情境化体育活动干预的效果。该研究通过全球体育活动问卷（GPAQ）主观测量确定总中度至剧烈体育活动（TMVPA），通过计步器测量总每周步数（TWS），并通过体育锻炼自我效能量表（PESES）测量体育活动自我效能。多变量协方差分析（MANCOVA）用于计算干预对从基线到六周以及干预后从基线到12周的TMVPA、TWS和体育活动自我效能的影响，同时控制TMVPA的预测试差异。结果显示，接受干预的参与者从预测试到6周，通过TMVPA（p = 0.027）、TWS（p = 0.032）以及运动自我效能（p = 0.000）测量的体育活动有显著增加。从基线到12周测量时，所有三个变量均报告无显著结果。总之，试点研究结果表明，该干预措施在六周内有效地使低SES的艾滋病毒感染者样本中的体育活动显著增加。仔细考虑行为因素，如自我效能，有助于低SES的WLWHA将定期体育活动作为管理健康的辅助疗法。
