Abstract

Most working women do not meet current guidelines for physical activity (PA). A 12-week pilot study tested a workplace, peer modeling PA intervention. Inactive female employees from a health system were randomized to an attention control group (ACG; n = 26) or an intervention group (IG; n = 26). The ACG received health information. The IG participated in six group sessions with an active peer model and received an exercise prescription and PA information. Pre and post measures were PA (ActiGraph), Estimated VO (cycle ergometer), resting heart rate (HR), glucose and lipids, and cardiovascular risk. Using hierarchical linear modeling, no significant group by time effects were found. Although PA increased in both groups, F( df = 1) = 11.4, p = .002, the IG had greater improvements in fitness (VO, HR) and cardiovascular risk (total cholesterol, triglyceride, low density lipoprotein [LDL], calculated risk score) compared with ACG. Results support repeating this intervention in a fully powered study.

摘要

大多数职业女性未达到当前的身体活动(PA)指南要求。一项为期12周的试点研究对一种工作场所同伴示范PA干预措施进行了测试。来自一个医疗系统的不活跃女性员工被随机分为注意力控制组(ACG;n = 26)或干预组(IG;n = 26)。ACG接受健康信息。IG与一名活跃的同伴示范者一起参加了六次小组会议,并收到了一份运动处方和PA信息。前后测量指标包括PA(ActiGraph)、估计的VO(自行车测力计)、静息心率(HR)、血糖和血脂以及心血管风险。使用分层线性模型,未发现显著的组间时间效应。尽管两组的PA均有所增加,F(自由度 = 1)= 11.4,p = .002,但与ACG相比,IG在体能(VO、HR)和心血管风险(总胆固醇、甘油三酯、低密度脂蛋白[LDL]、计算出的风险评分)方面有更大改善。结果支持在一项充分有力的研究中重复这种干预措施。
