Physical inactivity in Saudi women is high, even among young women (60% of university students are physically inactive). We aimed to investigate the effect of a physical activity intervention on daily walking among female students at a Saudi university.
Two hundred and seven female students (mean age: 22.6 ± 1.3; body mass index: 24.6 ± 5.9) participated in a parallel-group randomized trial. The intervention group wore pedometers and received health-promotion messages for 12 weeks through WhatsApp; the control group received a similar number of messages unrelated to health. Average daily steps and self-reported activity were assessed at baseline and after 3 months. Analysis followed an intention-to-treat approach. Group differences in average daily steps were assessed using a two (group) by 2 (time) ANOVA. F-tests for main effects and the interaction were evaluated; < 0.05 was considered significant.
There was a significant group-by-time interaction, that is, the intervention group had a significantly higher change in daily steps compared to the control group (+576 vs. -525; F = 4.33, = 0.04). Self-reported daily activity was not significantly different by group.
The intervention was effective at improving the number of daily steps in young women. Future studies could test this intervention among other student groups.
沙特女性身体活动不足的比例很高，即使在年轻女性中也是如此（60%的大学生身体活动不足）。我们旨在调查一项身体活动干预措施对沙特一所大学女生日常步行的影响。
207名女学生（平均年龄：22.6±1.3；体重指数：24.6±5.9）参与了一项平行组随机试验。干预组佩戴计步器，并通过WhatsApp接收为期12周的健康促进信息；对照组收到数量相似但与健康无关的信息。在基线和3个月后评估平均每日步数和自我报告的活动情况。分析采用意向性分析方法。使用二（组）乘二（时间）方差分析评估平均每日步数的组间差异。对主效应和交互作用进行F检验；P<0.05被认为具有显著性。
存在显著的组×时间交互作用，即干预组的每日步数变化显著高于对照组（+576步对 -525步；F = 4.33，P = 0.04）。自我报告的日常活动在组间无显著差异。
该干预措施在增加年轻女性的每日步数方面有效。未来的研究可以在其他学生群体中测试这种干预措施。
