Abstract

INTRODUCTION

Masked obesity (MO) is defined as a normal body mass index (BMI) with a high body fat percentage (%BF), and is associated with the onset of lifestyle-related diseases. However, little is known about the current status of MO. Therefore, we investigated the relationship of MO to physical characteristics and lifestyle habits among Japanese university students.

METHODS

Between 2011 and 2019, we conducted a survey of 10,168 males and 4,954 females with BMI within the normal range (18.5 ≤ BMI < 25 kg/m2). MO was defined as %BF ≥ 20% in males and %BF ≥ 30% in females. Students completed a questionnaire containing items about lifestyle habits. Systolic and diastolic blood pressures were measured, and hypertension was defined as systolic above 140 mmHg and/or diastolic blood pressure above 90 mmHg. A multivariate logistic regression analysis was performed to evaluate the relationships as follows: the relationship of masked obesity to self-reported lifestyle habits, ideal body image, and anthropometric measures; the relationship between hypertension and body indices.

RESULTS

The proportion of students with MO in 2019 was 13.4% in males and 25.8% in females, and the proportion of females increased over time. MO was associated with desire for weight loss (odds ratio, 95% confidence interval: 1.76, 1.53-2.02), intake of five macronutrients (0.79, 0.67-0.93), rice and wheat intakes (1.22, 1.01-1.47), sleep duration of < 7hr (0.85, 0.74-0.98), and exercise habit (0.71, 0.63-0.81) in males; and with balanced diet intake (0.79, 0.64-0.99) and exercise habit (0.65, 0.51-0.82) in females. There was a significant association of MO with hypertension in males (1.29, 1.09-1.53).

CONCLUSION

The percentage of female students with MO increased during the study period, and in males, MO may be a risk factor for hypertension. These results suggest that intervention for MO is needed in Japanese university students.

摘要

简介

隐匿性肥胖（MO）定义为正常体重指数（BMI）和高体脂百分比（%BF），与生活方式相关疾病的发生有关。然而，目前对于 MO 的现状知之甚少。因此，我们调查了 MO 与日本大学生身体特征和生活方式习惯的关系。

方法

在 2011 年至 2019 年间，我们对 10168 名男性和 4954 名 BMI 在正常范围内（18.5≤BMI＜25kg/m2）的男性和女性进行了一项调查。MO 定义为男性的%BF≥20%和女性的%BF≥30%。学生们完成了一份包含生活方式习惯项目的问卷。测量了收缩压和舒张压，高血压定义为收缩压高于 140mmHg 和/或舒张压高于 90mmHg。进行了多变量逻辑回归分析，以评估以下关系：隐匿性肥胖与自我报告的生活方式习惯、理想体型和人体测量指标的关系；高血压与身体指数的关系。

结果

2019 年男性学生中 MO 的比例为 13.4%，女性为 25.8%，且女性的比例随时间推移而增加。MO 与减肥欲望（比值比，95%置信区间：1.76，1.53-2.02）、五种宏量营养素的摄入（0.79，0.67-0.93）、大米和小麦的摄入（1.22，1.01-1.47）、<7 小时的睡眠时间（0.85，0.74-0.98）和运动习惯（0.71，0.63-0.81）有关；与男性的均衡饮食摄入（0.79，0.64-0.99）和运动习惯（0.65，0.51-0.82）有关；与女性的高血压有关（1.29，1.09-1.53）。
