Associated factors of masked obesity in female college students

Abstract

Objective The status of masked obesity in female college students and the related factors were investigated to provide a theoretical reference for instructing the physical health education of female college students and improving their physical exercises.

Methods Body composition tests were performed on 2 975 female college students, selected from 3 colleges in North China by using cluster sampling method during October to December in 2018, and their basic information and lifestyle were investigated using questionnaires.

Results The incidence of masked obesity among female college students was 33.18%, of which 2.53% came from low-weight people. The difference in the incidence of masked obesity among female college students with different takeout frequencies was statistically significant (χ ² = 21.98, P<0.01). Compared with those who never take takeaway, people who take takeaway every day have an increased risk of masked obesity ( OR = 1.49, 95% CI = 0.76-2.91). The difference in the incidence of masked obesity with the frequency of eating midnight snack was statistically significant (χ ² = 20.80, P<0.05). The difference in the incidence of masked obesity among female college students with different exercise time was statistically significant (χ ² = 18.49, P< 0.01). Compared with exercise time above 60 min/d, female college students who are not exercising have an increased risk of masked obesity ( OR = 3.20, 95% CI = 1.63-6.30). The difference in the incidence of masked obesity among female college students with different weight satisfaction was statistically significant (χ ² = 217.54, P<0.01). Compared with female college students who were satisfied with weight, female college students who were not satisfied with weight had an increased risk of masked obesity ( OR =3.47, 95% CI = 1.91-6.31). The difference in the incidence of masked obesity in different weight-down plans is statistically significant (χ ² = 186.40, P<0.01). Those who want to lose weight have a higher risk of developing masked obesity than those who want to gain weight ( OR = 18.11, 95% CI = 5.54-50.13).

Conclusion Female college students who drink a small amount of water, eat takeaways often, eat midnight snacks, do not exercise, and are not satisfied with their weight are more likely to develop masked obesity.

【摘要】 目的 了解女大学生隐性肥胖现状及相关因素, 为指导女大学生的体育健康教育和锻炼促进提供理论依 据。 方法 于2018年10—12月采用整群抽样方法, 对华北地区3所高校的2 975名女大学生进行身体成分测试, 并采用 问卷对其基本信息和生活方式进行调查。 结果 女大学生隐性肥胖的检出率为33.18%, 其中2.53%来自于低体重人群。 女大学生中, 吃外卖频率不同的隐性肥胖发生率差异有统计学意义 (χ ²=21.98, P<0.01), 每天都吃的相对于从来不吃的, 发生隐性肥胖的风险增加 ( OR =1.49, 95% CI =0.76〜2.91);吃夜宵频率不同的隐性肥胖发生率差异有统计学意义 (χ ² = 20.80, P<0.01), 每天都吃的发生隐性肥胖的风险增加 ( OR =1.78, 95% CI =0.55〜2.54);运动时间不同的隐性肥胖发生率的 差异有统计学意义 (χ ²=18.49, P<0.01), 不运动的发生隐性肥胖的风险增加 ( OR =3.20, 95% CI =1.63〜6.30)。对体重满意 度不同的隐性肥胖发生率差异有统计学意义 (χ ²=217.54, P<0.01), 不满意的发生隐性肥胖的风险增加 ( OR = 3.47, 95% CI = 1.91〜6.31);体重下步计划不同的隐性肥胖发生率差异有统计学意义 (χ ²=186.40, P<0.01), 想减肥的发生隐性肥胖的风 险增加 ( OR =18.11, 95% CI =5.54〜50.13)。 结论 经常吃外卖、经常吃宵夜、不运动、对自身体重不满意和有控制体重计划 的女大学生发生隐性肥胖的可能性成倍增加。
