目的：（1）利用现有的研究来估计大学新生在大学第一年的体重增加量。 (2) 确定新生体重增加的潜在预测因素。方法：2008 年 11 月进行了一项荟萃分析。分析的重点是 1985 年至 2008 年在 MEDLINE、Web of Science 和 PsycINFO 数据库上发表的英文科学期刊上发表的文章，排除了大一之后体重变化的研究。结果：24 项研究符合纳入标准。基于 3,401 个案例的汇总样本。平均体重增加为 3.86（95% 置信区间 [CI] = 3.81-3.91）磅。增加体重的潜在因素包括最近的节食、高基线体重和心理压力。结论：大学第一年是体重问题的脆弱时期。需要进一步的研究来更好地了解新生体重增加，并根据体重增加的预测因素制定适当的预防策略。
Objective: (1) TO use the available research to estimate the amount of weight gained by college freshman during their first year of college. (2) To identify potential predictors of freshman weight gain. Methods: A meta-analysis was conducted in November 2008. The analysis focused on articles published in English scientific journals between 1985 and 2008 available on the MEDLINE, Web of Science, and PsycINFO databases and excluded studies of weight change over periods beyond freshman year. Results: Twenty-four studies met the inclusion criteria. Based on a pooled sample of 3,401 cases. mean weight gain was 3.86 (95% confidence intervals [CI] = 3.81-3.91) lbs. Potential contributors to gain were recent dieting, high baseline weight, and psychological stress. Conclusions: The first year of college is a period Of vulnerability for weight problems. Further research is needed to better understand freshman weight gain and devise appropriate prevention strategies based on predictors of gain.
