This analysis of secondary outcome measures of a randomized controlled trial was conducted to study the effect of a one-year three-component (cognitive behavioural therapy, diet, exercise) lifestyle intervention (LSI), with or without additional Short Message Service (SMS) support, on physical activity and aerobic capacity in overweight or obese women with polycystic ovary syndrome (PCOS). Women diagnosed with PCOS and a BMI > 25 kg/m were randomly assigned to LSI with SMS support (SMS+, = 60), LSI without SMS support (SMS-, = 63) or care as usual (CAU, = 60) in order to lose weight. Based on results from the International Physical Activity Questionnaire (IPAQ), we found a significant within-group increase after one year for SMS+ in the high physical activity category (+31%, < 0.01) and sitting behaviour decreased (Δ -871 min/week, < 0.01). Moreover, the peak cycle ergometer workload increased within SMS+ (Δ +10 watts, < 0.01). The SMS+ group also demonstrated a significantly different increase in walking metabolic equivalent of task minutes (METmin)/week compared with CAU after one year (Δ 1106 METmin/week, < 0.05). Apart from this increase in walking activity, no other between-group differences were found in this trial. Overall, based on within-group results, SMS support seemed to help with improving physical activity and aerobic capacity and decreasing sedentary behaviour.
本研究对一项随机对照试验的次要结局指标进行了分析，以探讨为期一年的包含认知行为疗法、饮食和运动的三要素生活方式干预（LSI），无论有无额外的短信服务（SMS）支持，对超重或肥胖多囊卵巢综合征（PCOS）女性的身体活动和有氧能力的影响。诊断为PCOS且体重指数（BMI）>25kg/m²的女性被随机分配至接受短信支持的LSI组（短信支持组，n = 60）、无短信支持的LSI组（无短信支持组，n = 63）或常规护理组（CAU组，n = 60）以减重。根据国际体力活动问卷（IPAQ）的结果，我们发现，一年后短信支持组在高强度身体活动类别中组内有显著增加（+31%，P<0.01），久坐行为减少（Δ -871分钟/周，P<0.01）。此外，短信支持组的峰值自行车测力计工作量增加（Δ +10瓦，P<0.01）。一年后，短信支持组与CAU组相比，每周步行代谢当量任务分钟数（METmin）的增加也有显著差异（Δ 1106 METmin/周，P<0.05）。除了步行活动的增加外，本试验未发现其他组间差异。总体而言，基于组内结果，短信支持似乎有助于改善身体活动和有氧能力，并减少久坐行为。
