Abstract

ObjectiveOur study is to evaluate the association between body mass index (BMI) and vital capacity of college students of Zhuang Nationality in China.Methods463 college students of Zhuang Nationality from Guangxi Medical University were selected. Basic information, body composition and vital capacity of college students were measured. According to the level of BMI, college students were divided into four groups (BMI<18.5, 18.5≤BMI<23.9, 23.9≤BMI<27.9 and BMI≥27.9). Multivariate logistic regression analysis was performed to assess the association between BMI and vital capacity.ResultsIn male college students, there was no significant difference in vital capacity between the four groups (3029.54±869.25, 3347.06±784.54, 3540.00±805.35 and 3966.50±350.2, P=0.0727, respectively). Multivariate regression analysis showed that after adjusting for confounding factors, no significant association was observed between BMI and vital capacity (OR=115.02, 95% CI: -555.58∼785.63; OR=-166.58, 95% CI: -1684.56∼1351.41; OR=-484.01, 95% CI:-3504.53, 2536.51, respectively. BMI<18.5 group served as reference group). In female college students, there was also no significant difference in vital capacity between the four groups (2455.15±574.4, 2555.06±637.03, 2750.33±1224.05 and 2473.00±159.06, P=0.4011, respectively). Multivariate regression analysis showed that after adjusting for confounding factors, no significant association was observed between BMI and vital capacity (OR=-88.88, 95% CI: -333.59∼155.84; OR=20.00, 95% CI: -694.39∼734.39; OR=2.86, 95% CI: -1830.58, 1836.3, respectively. BMI<18.5 group served as reference group).ConclusionThere was no evidence that BMI is associated with vital capacity in college students of Zhuang Nationality.

Highlights

In recent years, overweight and obesity have become global epidemics, and are attributed to changes in living standards in developed countries and in developing countries [1]

Summary

Introduction

Overweight and obesity have become global epidemics, and are attributed to changes in living standards in developed countries and in developing countries [1]. Research results have shown that 35% of adults aged ≥20 years were reported to be overweight and 11% were reported to be obese in 2008 year [2,3,4]. In 2012 year, more than 40 million children aged ≥5 years were reported to be overweight or obese all over the world [7, 8]. Obesity or/and overweight are a major risk factor for non-communicable disorders as well as cardiovascular disorders [9], such as hypertension [10], diabetes mellitus [11] and dyslipidemia [12], and is closely related to morbidity and mortality. The importance of weight control has been emphasized for the primary and secondary prevention of lifestyle-related disorders on a global scale
