一项前瞻性研究将睡眠时间型作为大学新生体重增加和体重指数 (BMI) 增加的预测因素。在基线时，使用简化版的早晚问卷将 137 名大学新生分为早起型、中性型或晚间型。此外，还收集了有关体重、体重指数和健康习惯（例如垃圾食品和饮酒）的信息。这些额外的措施包括描述性调查问卷、匹兹堡睡眠质量指数、国际体育活动调查问卷、格雷-唐纳德饮食模式调查问卷以及积极和消极影响量表。参与者包括 79 名女性和 80 名男性，平均年龄为 18.25 (SD=0.56) 岁。八周后，参与者（N = 54）返回完成后续措施，这些措施与基线评估相同，但描述性调查问卷除外，其中删除了人口统计问题。与早晨/中性类型相比，晚上类型的 BMI 增益显着更高 (p<0.05)。健康行为不因时间类型而异。未来的研究应寻求阐明时间型-BMI/体重增加关系的潜在机制。
A prospective study of chronotype as a predictor of increased weight gain and body mass index (BMI) among college freshman was undertaken. At baseline, 137 college freshmen were characterized as morning, neutral, or evening types using the reduced version of the Morningness-Eveningness Questionnaire. Additionally, information was collected regarding weight, BMI, and health habits (e.g., junk food and alcohol consumption). These additional measures consisted of a descriptive questionnaire, the Pittsburgh Sleep Quality Index, the International Physical Activity Questionnaire, the Gray-Donald Eating Patterns Questionnaire, and the Positive and Negative Affect Scale. Participants included 79 females and 80 males with a mean age of 18.25 (SD=0.56) yrs. Eight weeks later, participants returned (N=54) to complete follow-up measures, which were identical to baseline assessments with the exception of the descriptive questionnaire, in which demographic questions were removed. Evening types had a significantly greater BMI gain (p<0.05) when compared with morning/neutral types. Health behaviors did not differ by chronotype. Future studies should seek to clarify the mechanisms underlying the chronotype-BMI/weight gain relationship.
