OBJECTIVES AND PARTICIPANTS: Changes in body weight, composition, and size were examined in college freshmen at the beginning (initial, n = 240) and end of fall semester 2007 (n = 214) and the end of spring semester 2008 (n = 205).
Height, weight, body composition, and waist and hip measurements were assessed.
Mean weight, body mass index (BMI), absolute and percent body fat all increased significantly over fall semester and the academic year. About 31% of freshmen lost > or =5 lbs. Mean academic year weight gain was 2.6 lbs (entire group) and 6.0 lbs (weight gainers); body fat increased by 4.4 lbs in the weight gainers. A significant correlation (r = .509) was found between weight change and waist circumference change, but not between weight change and waist to hip ratio change.
Freshmen weight gain is associated with increases in body fat and waist circumference, which may be troublesome should the trend continue throughout college.
目的和参与者：在 2007 年秋季学期初（初始，n = 240）和结束时（n = 214）以及 2008 年春季学期结束时（n = 205），对大学新生的体重、组成和大小变化进行了检查。
测量了身高、体重、身体成分以及腰围和臀围。
平均体重、体重指数（BMI）、绝对体脂和体脂百分比在秋季学期和整个学年均显著增加。约 31%的新生体重减轻>或=5 磅。整个年级的平均学年体重增加为 2.6 磅（整个组）和 6.0 磅（体重增加者）；体重增加者的体脂增加了 4.4 磅。体重变化与腰围变化之间存在显著相关性（r =.509），但与体重变化和腰臀比变化之间无相关性。
新生体重增加与体脂和腰围增加有关，如果这种趋势在整个大学期间持续下去，可能会令人烦恼。
