To conduct a prospective, longitudinal study examining weight fluctuation and its predictors before and during the first year of college.
Men (n = 266) and women (n = 341) enrolled at Dartmouth College (age range: 16 to 26; body mass index range: 15.0 to 42.9) provided self-reports of weight and height and completed measures of self-esteem, eating habits, interpersonal relationships, exercise patterns, and disordered eating behaviors both in their senior year of high school and either 3, 6, or 9 months into college.
Self-reported weight was the primary outcome indicator.
Analyses indicated that both men and women gained a significant amount of weight (3.5 and 4.0 pounds, respectively). Weight gain occurred before November of the first academic year and was maintained as the year progressed. College freshmen gain weight at a much higher rate than that of average American adults. For men, frequently engaging in exercise predicted weight gain. Having troublesome relationships with parents also predicted weight gain in men, whereas for women, having positive relationships with parents predicted weight gain.
Understanding the predictors of early college weight gain may aid in the development of prevention programs.
进行一项前瞻性纵向研究，调查大学一年级之前及期间的体重波动情况及其预测因素。
达特茅斯学院的男性（n = 266）和女性（n = 341）（年龄范围：16至26岁；体重指数范围：15.0至42.9）提供了自己的体重和身高报告，并在高中最后一年以及大学入学3、6或9个月时完成了自尊、饮食习惯、人际关系、运动模式和饮食失调行为的测量。
自我报告的体重是主要结局指标。
分析表明，男性和女性均体重显著增加（分别增加3.5磅和4.0磅）。体重增加发生在第一学年11月之前，并在这一年中持续。大学新生体重增加的速度远高于美国成年人群体。对于男性，经常锻炼预示着体重增加。与父母关系紧张也预示着男性体重增加，而对于女性，与父母关系良好预示着体重增加。
了解大学早期体重增加的预测因素可能有助于制定预防计划。
