Admission to university influences lifestyle behaviors and is marked by a daily routine of accumulation of activities that can interfere with sleep duration, affecting food choices and meal consumption habits throughout the day. To analyze the association between short sleep duration and skipping main meals among university students. We conducted a cross-sectional study with 1,608 university students aged between 16 and 25 years, who were enrolled in full-time undergraduate courses at a public university in the Midwestern region of Brazil. Information on skipping breakfast, lunch, and dinner was collected through the question "On average, how often do you eat the following meals?". Given the lack of a uniform criterion to define "skipping a meal", in the present study, any answer that did not correspond to the daily consumption of the meal was classified as meal skipping, based on the recommendation of the Dietary Guidelines for the Brazilian Population. Short sleep duration was determined according to sleep time during the night (≤ 6 hours for those aged ≥18 years and ≤ 7 hours for those under 18 years of age). Associations were estimated using adjusted Poisson regression models. The prevalences of skipping breakfast, lunch, and dinner were of 51.0%, 13.9%, and 35.6% respectively. Short sleep duration was observed in 27.2% of the study population. After adjusting for confounding variables, short sleep duration was positively associated with skipping breakfast (adjusted prevalence ratio [PRadj] = 1.20; 95% confidence interval [95%CI] = 1.08-1.34) and skipping lunch (PRadj = 1.64; 95%CI = 1.27-2.12). University students presented a high prevalence of skipping main meals. Short sleep duration was directly associated with skipping two major meals of the day: breakfast and lunch.
进入大学会影响生活方式行为，其特点是日常活动不断累积，这可能会干扰睡眠时间，进而影响全天的食物选择和用餐习惯。
为分析大学生短睡眠时间与不吃正餐之间的关联。
我们对1608名年龄在16至25岁之间的大学生进行了一项横断面研究，这些学生就读于巴西中西部地区一所公立大学的全日制本科课程。通过“平均而言，你多久吃一次以下餐食？”这一问题收集不吃早餐、午餐和晚餐的信息。鉴于缺乏统一的标准来定义“不吃一餐”，在本研究中，根据《巴西人群膳食指南》的建议，任何不符合每日用餐情况的回答都被归类为不吃一餐。短睡眠时间根据夜间睡眠时间确定（18岁及以上者≤6小时，18岁以下者≤7小时）。使用调整后的泊松回归模型估计关联。
不吃早餐、午餐和晚餐的患病率分别为51.0%、13.9%和35.6%。27.2%的研究人群存在短睡眠时间。在对混杂变量进行调整后，短睡眠时间与不吃早餐（调整后的患病率比[PRadj]=1.20；95%置信区间[95%CI]=1.08 - 1.34）和不吃午餐（PRadj=1.64；95%CI=1.27 - 2.12）呈正相关。
大学生不吃正餐的患病率较高。短睡眠时间与不吃一天中的两顿主要餐食：早餐和午餐直接相关。
