Predictors of first semester and year weight change by gender were examined.
The participants were 304 freshmen recruited over three years (September 2010, 2011, & 2012).
Psychosocial and lifestyle variables and weight were assessed at the beginning and end of the Fall semester and end of the Spring semester.
The average weight gain over the year was 6.38 lbs for males versus 4.38 lbs for females. In the first semester, alcohol use was associated with weight gain among males. For females, higher levels of physical activity and lower BMI were associated with weight gain. At the end of the year, happiness was negatively associated with weight gain among males and physical activity positively associated with weight gain in females.
Alcohol consumption in males and physical activity in females produced positive associations with weight gain with most of the weight gained during the first semester. This implies that efforts to prevent weight gain in college freshmen need to be tailored by gender and focus on first semester.
研究按性别划分的第一学期及一学年体重变化的预测因素。
参与者为在三年时间里（2010年9月、2011年和2012年）招募的304名新生。
在秋季学期开始和结束时以及春季学期结束时评估心理社会和生活方式变量及体重。
男性一学年的平均体重增加6.38磅，女性为4.38磅。在第一学期，饮酒与男性体重增加有关。对于女性，较高的身体活动水平和较低的体重指数与体重增加有关。在学年末，幸福感与男性体重增加呈负相关，而身体活动与女性体重增加呈正相关。
男性饮酒和女性身体活动与体重增加呈正相关，且大部分体重增加发生在第一学期。这意味着预防大学新生体重增加的努力需要按性别量身定制，并关注第一学期。
