Overweight, obesity and physical activity are considered modifiable factors related to development of chronic diseases. Taking into account physical activity patterns in college students, it is necessary to establish its association with the excessive weight in order to prevent and to decrease the prevalence of future chronic diseases.
The aim of this study was to determine the association between excessive weight and physical inactivity among college students.
An analytical cross sectional study was carried out in 2013 among college students from a private university of Bucaramanga, Colombia. Students (n=306) 18 to 25 years old were included using simple random sampling. An interview was realized using a survey that included the International Physical Activity Questionnaire (IPAQ), together with socio demographic variables. An assessment of body composition was realized in order to measure height, weight, body mass index (BMI), total fat percentage, and waist and hip circumferences. A trained professional in physical activity was in charge of data collection and anthropometric measurements. This study was approved by the university research and ethics committee. Participation was both voluntary and anonymous. All data were analyzed in compliance with the Helsinki Declaration. Written consent was signed by every participant of the study. A descriptive analysis of the studied population's general characteristics was realized. The association between excessive weight and physical inactivity was estimated using regression logistic models that allows estimate row and adjusted Odds Ratios (OR).
An excessive weight was observed in 26.47% of the students, among which 20.26% were overweight and 6.21% obese, according to BMI cutoff. Taking into account the total fat percentage, 12.09% of the students were in risk of becoming obese and 10.13% were already obese. 50.56% of the students practiced very little weekly physical activity. The median of daily sedentary lifestyle was 12 hours, with an interquartile range of 4 hours. A statistically significant association was found between excessive weight and sedentary behavior, according to the total fat method (adjusted OR: 1.11, CI 95%: 1.01-1.23).
College students' health behavior is often inadequate in terms of physical activity and dietary habits. Our study observed an association between physical inactivity and excessive weight. Physical inactivity is an important lifestyle factor related to chronic diseases. Further research should focus on determinants to increase their physical activity and to improve their daily lifestyle in order to lower the risk of future diseases.
超重、肥胖和身体活动被认为是与慢性病发展相关的可改变因素。考虑到大学生的身体活动模式，有必要确定其与超重之间的关联，以预防和降低未来慢性病的患病率。
本研究的目的是确定大学生中超重与身体活动不足之间的关联。
2013年对哥伦比亚布卡拉曼加一所私立大学的大学生进行了一项分析性横断面研究。采用简单随机抽样纳入18至25岁的学生（n = 306）。使用包含国际身体活动问卷（IPAQ）以及社会人口统计学变量的调查问卷进行访谈。为了测量身高、体重、体重指数（BMI）、总脂肪百分比以及腰围和臀围，进行了身体成分评估。一名受过身体活动培训的专业人员负责数据收集和人体测量。本研究得到了大学研究与伦理委员会的批准。参与是自愿且匿名的。所有数据均按照《赫尔辛基宣言》进行分析。研究的每位参与者都签署了书面同意书。对研究人群的一般特征进行了描述性分析。使用回归逻辑模型估计超重与身体活动不足之间的关联，该模型允许估计原始和调整后的优势比（OR）。
根据BMI临界值，26.47%的学生超重，其中20.26%超重，6.21%肥胖。考虑到总脂肪百分比，12.09%的学生有肥胖风险，10.13%的学生已经肥胖。50.56%的学生每周身体活动极少。每日久坐生活方式的中位数为12小时，四分位间距为4小时。根据总脂肪方法，超重与久坐行为之间存在统计学显著关联（调整后的OR：1.11，95%CI：1.01 - 1.23）。
大学生在身体活动和饮食习惯方面的健康行为往往不足。我们的研究观察到身体活动不足与超重之间存在关联。身体活动不足是与慢性病相关的重要生活方式因素。进一步的研究应关注增加身体活动和改善日常生活方式的决定因素，以降低未来患病风险。
