Abstract：
Postmenopausal Hispanic/Latina (N = 254) women with a body mass index (BMI) ≥ 25 kg/m2 were randomized to an intervention to reduce sitting time or a comparison condition for 12 weeks. The standing intervention group received three in-person health-counseling sessions, one home visit, and up to eight motivational interviewing calls. The heart healthy lifestyle comparison group (C) received an equal number of contact hours to discuss healthy aging. The primary outcome was 12-week change in sitting time measured via thigh-worn activPAL. Group differences in outcomes were analyzed using linear mixed-effects models. Participants had a mean age of 65 (6.5) years, preferred Spanish language (89%), BMI of 32.4 (4.8) kg/m2, and sat for an average of 540 (86) minutes/day. Significant between-group differences were observed in reductions of sitting time across the 12-week period [Mdifference (SE): C - 7.5 (9.1), SI - 71.0 (9.8), p < 0.01]. Results demonstrate that coaching models to reduce sitting are feasible and effective.
摘要：
绝经后西班牙裔/拉丁裔（N=254）体重指数（BMI）≥25kg/m2的女性被随机分配到干预措施，以减少坐位时间或比较条件，持续12周。常设干预组接受了三次面对面的健康咨询，一次家访,和多达八个励志面试电话。心脏健康生活方式比较组(C)接受相同数量的接触小时数来讨论健康衰老。主要结果是通过大腿穿着activPAL测量的坐着时间的12周变化。使用线性混合效应模型分析结果的组间差异。参与者的平均年龄为65（6.5）岁，首选西班牙语（89%），BMI为32.4（4.8）kg/m2，平均为540（86）分钟/天。在12周期间，观察到坐下时间减少的组间差异显着[M差异（SE）：C-7.5（9.1），SI-71.0（9.8），p<0.01]。结果表明，减少坐姿的教练模式是可行和有效的。
