Weight gain occurs frequently in men aged 25-40. This study compared the effectiveness of a clinic-based and a home-based intervention with a no-treatment control group in preventing this weight gain.
Men (n=67)-aged 25 to 40, sedentary, with a body mass index of 22 to 30, recruited from the University of Pittsburgh-were randomly assigned to 4-month treatments focused on increasing aerobic exercise and reducing fat intake through a clinic-based (CB) or a home-based (HB) program, or to a delayed-treatment control group. Subjects were reassessed at 4 months.
Adherence and outcome did not differ significantly between the CB and HB programs, except that CB subjects recorded their food intake more frequently, and a greater number of CB subjects achieved a total of 120 miles of exercise over the 4 months. Subjects in the two intervention conditions combined lost significantly more weight (-1.6+/-2.5 kg) than control subjects, who gained 0.2+/-1.9 kg (p<0.01); this effect of treatment was seen primarily in men with a body mass index of 27 to 30 (-2.7 kg for CB and HB combined vs. + 1.5 kg for control). Treated subjects also had somewhat greater improvements in body composition, aerobic fitness, and weekly energy expenditure than controls, although these differences did not reach significance.
Both CB and HB intervention show promise in preventing weight gain in young men, especially in those who are slightly overweight. Larger studies, using more representative samples of young men, appear warranted.
25至40岁男性体重增加的情况很常见。本研究比较了基于诊所的干预、基于家庭的干预与无治疗对照组在预防这种体重增加方面的效果。
从匹兹堡大学招募了67名年龄在25至40岁、久坐不动、体重指数在22至30之间的男性，将他们随机分配到为期4个月的治疗组，治疗组通过基于诊所的（CB）或基于家庭的（HB）项目专注于增加有氧运动和减少脂肪摄入，或者分配到延迟治疗对照组。在4个月时对受试者进行重新评估。
CB和HB项目在依从性和结果方面没有显著差异，只是CB组受试者更频繁地记录他们的食物摄入量，并且更多的CB组受试者在4个月内总共完成了120英里的运动。两种干预条件下的受试者组合减重（-1.6±2.5千克）明显多于对照组，对照组增重0.2±1.9千克（p<0.01）；这种治疗效果主要见于体重指数为27至30的男性（CB和HB组合减重2.7千克，而对照组增重1.5千克）。与对照组相比，接受治疗的受试者在身体成分、有氧适能和每周能量消耗方面也有一定程度的更大改善，尽管这些差异不显著。
CB和HB干预在预防年轻男性体重增加方面都显示出前景，尤其是在那些略有超重的男性中。似乎有必要进行更大规模的研究，使用更具代表性的年轻男性样本。
