Students in the US have been shown to gain weight during their first year at university. This study examined whether students in Britain have a similar weight change during their first year at university, and tested the hypothesis that stress plays a role. A cross-sectional survey was conducted to assess stress and perceived weight change. Two hundred and sixty eight students at University College London completed the questionnaire at the end of their first year of university. On average, students reported a significant weight increase (1.53 kg+/-2.70, p<0.001), although there was considerable variation, with 55% of the sample reporting weight gain, 12% weight loss, and 33% remaining stable. Logistic regression analyses demonstrated that stress was associated with greater risk of weight gain (OR, 1.27, 95% CI, 1.12 to 1.44, p=0.001) and weight loss (1.33, 1.10 to 1.61, p=0.003), but associations were stronger among women. The associations remained unchanged after adjustment for health behaviours. Our findings confirm a modest weight gain over the first year at university, which was associated with higher levels of perceived stress in women.
研究表明，美国学生在大学一年级时体重会增加。本研究调查了英国学生在大学一年级期间体重是否有类似变化，并检验了压力起作用这一假设。进行了一项横断面调查以评估压力和感知到的体重变化。伦敦大学学院的268名学生在大学一年级结束时完成了问卷。平均而言，学生报告体重显著增加（1.53千克±2.70，p<0.001），尽管存在相当大的差异，55%的样本报告体重增加，12%体重减轻，33%保持稳定。逻辑回归分析表明，压力与体重增加（比值比，1.27，95%置信区间，1.12至1.44，p=0.001）和体重减轻（1.33，1.10至1.61，p=0.003）的风险增加有关，但在女性中关联更强。在对健康行为进行调整后，这些关联保持不变。我们的研究结果证实，在大学一年级期间体重有适度增加，这与女性更高水平的感知压力有关。
