Weight loss was examined among women and men veterans in a clinical trial comparing Aspiring for Lifelong Health (ASPIRE), a "small changes" weight loss program using either mixed-sex group-visit or telephone-based coaching, to MOVE!(®) , the usual mixed-sex group-based program.
Linear mixed-effects models were used to calculate adjusted percent weight change at 12 months by sex and compare outcomes across arms within sex.
Analyses included 72 women (ASPIRE-Phone = 26; ASPIRE-Group = 26; MOVE! = 20) and 409 men (ASPIRE-Phone = 136; ASPIRE-Group = 134; MOVE! = 139). At 12 months, women displayed significant weight loss from baseline in ASPIRE-Group (-2.6%) and MOVE! (-2.7%), but not ASPIRE-Phone (+0.2%). Between-arm differences in weight change among women were: ASPIRE-Group versus ASPIRE-Phone, -2.8% (P = 0.15); MOVE! versus ASPIRE-Phone, -2.8% (P = 0.20); and ASPIRE-Group versus MOVE!, 0.0% (P = 1.0). At 12 months, men lost significant weight from baseline across arms (ASPIRE-Phone, -1.5%; ASPIRE-Group, -2.5%; MOVE!, -1.0%). Between-arm differences in weight change among men were: ASPIRE-Group versus ASPIRE-Phone, -0.9% (P = 0.23); MOVE! versus ASPIRE-Phone, +0.5% (P = 0.76); ASPIRE-Group versus MOVE!, -1.5% (P = 0.03).
Mixed-sex, group-based programs can result in weight loss for both women and men veterans.
在一项临床试验中，对女性和男性退伍军人的体重减轻情况进行了研究。该试验将“追求终身健康”（ASPIRE）这一采用男女混合小组就诊或电话指导的“小改变”减肥计划，与常规的男女混合小组计划“行动！（MOVE!）”进行了比较。
使用线性混合效应模型按性别计算12个月时的调整后体重变化百分比，并比较各性别组内不同方案的结果。
分析纳入了72名女性（ASPIRE电话指导组 = 26人；ASPIRE小组就诊组 = 26人；行动！组 = 20人）和409名男性（ASPIRE电话指导组 = 136人；ASPIRE小组就诊组 = 134人；行动！组 = 139人）。在12个月时，ASPIRE小组就诊组（-2.6%）和行动！组（-2.7%）的女性体重相较于基线有显著减轻，但ASPIRE电话指导组（+0.2%）没有。女性体重变化的组间差异为：ASPIRE小组就诊组与ASPIRE电话指导组，-2.8%（P = 0.15）；行动！组与ASPIRE电话指导组，-2.8%（P = 0.20）；ASPIRE小组就诊组与行动！组，0.0%（P = 1.0）。在12个月时，各方案组的男性体重相较于基线均有显著减轻（ASPIRE电话指导组，-1.5%；ASPIRE小组就诊组，-2.5%；行动！组，-1.0%）。男性体重变化的组间差异为：ASPIRE小组就诊组与ASPIRE电话指导组，-0.9%（P = 0.23）；行动！组与ASPIRE电话指导组，+0.5%（P = 0.76）；ASPIRE小组就诊组与行动！组，-1.5%（P = 0.03）。
男女混合的小组计划可使女性和男性退伍军人实现体重减轻。
