The current study was a randomized controlled trial investigating the effect of an innovative, short-term lifestyle intervention on weight gain in female freshman college students.
Ninety-five freshmen were recruited from a large public university in the United States.
Participants completed baseline assessments and were randomized to a 5-session, 4-week intervention or wait-list control, with assessments at posttest and 3-month follow-up.
The hypothesized time by group interaction was not significant, p = .393; however, trends suggested that control participants maintained baseline weight, whereas intervention participants lost -2.07 kg by posttest but regained 1.05 kg at follow-up. Significantly more intervention participants (47.0%) decreased their daily caloric intake by ≥ 200 kcal compared with control (31.7%), p = .050.
Brief intervention to prevent weight gain was not effective in this sample. Future studies should investigate lengthening the intervention to enhance effectiveness and increasing recruitment to improve statistical power.
本研究为一项随机对照试验，旨在探究一种创新的短期生活方式干预对大学一年级女生体重增加的影响。
从美国一所大型公立大学招募了95名新生。
参与者完成基线评估后，被随机分为接受为期5节、为期4周的干预组或等待名单对照组，并在测试后和3个月随访时进行评估。
假设的组间时间交互作用不显著，p = 0.393；然而，趋势表明，对照组参与者维持了基线体重，而干预组参与者在测试后体重减轻了2.07千克，但在随访时又恢复了1.05千克。与对照组（31.7%）相比，显著更多的干预组参与者（47.0%）将每日热量摄入减少了≥200千卡，p = 0.050。
在该样本中，预防体重增加的简短干预无效。未来的研究应探讨延长干预时间以提高有效性，并增加招募人数以提高统计效力。
