OBJECTIVE
An intervention using Wi-Fi scales and graphic e-mail feedback, the caloric titration method (CTM), to reduce age-related weight gain over 1 year among college students was evaluated.
METHODS
First-year college students (n = 167) were randomized to CTM or control (C) groups and provided Wi-Fi scales. The CTM group was instructed to weigh daily, view a weight graph e-mailed to them after weighing, and try to maintain their weight. The C group could weigh at any time but did not receive feedback. At 6 months and 1 year, the C group provided weights. For intention to treat analysis, an adjusted mixed model was used to analyze the effect of the intervention.
RESULTS
Baseline body mass index was 22.9 ± 3.0 kg/m(2) . Ninety-five percent of the CTM participants weighed ≥ 3 times/week, compared to 15% in the C group (P < 0.001). After 1 year, the C group had gained 1.1 ± .4 kg whereas the CTM group lost 0.5 ± 3.7 kg (F = 3.39, P = 0.035). The difference in weight change between the two groups at 1 year was significant (P = 0.004). Retention was 81%.
CONCLUSIONS
CTM intervention was effective in preventing age-related weight gain in young adults over 1 year and thus offers promise to reduce overweight and obesity.
目的
评估一种使用Wi-Fi秤和图形电子邮件反馈的干预措施，即热量滴定法（CTM），以减少大学生一年内与年龄相关的体重增加。
方法
将一年级大学生（n = 167）随机分为CTM组或对照组（C组），并为他们提供Wi-Fi秤。CTM组被要求每天称重，查看称重后通过电子邮件发送给他们的体重图表，并努力维持体重。C组可以随时称重，但不接受反馈。在6个月和1年时，C组提供体重数据。对于意向性分析，使用调整后的混合模型分析干预效果。
结果
基线体重指数为22.9±3.0kg/m²。95%的CTM参与者每周称重≥3次，而C组为15%（P<0.001）。1年后，C组体重增加了1.1±0.4kg，而CTM组体重减轻了0.5±3.7kg（F = 3.39，P = 0.035）。两组在1年时体重变化的差异具有统计学意义（P = 0.004）。保留率为81%。
结论
CTM干预在预防年轻人1年内与年龄相关的体重增加方面是有效的，因此有望减少超重和肥胖。
