摘要
Objective: Our study is to evaluate the association between body mass index (BMI) and vital capacity of college students of Zhuang Nationality in China. Methods: 463 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. Results: In 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 similar to 785.63; OR=-166.58, 95% CI: -1684.56 similar to 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 similar to 155.84; OR=20.00, 95% CI: -694.39 similar to 734.39; OR=2.86, 95% CI: -1830.58, 1836.3, respectively. BMI< 18.5 group served as reference group). Conclusion: There was no evidence that BMI is associated with vital capacity in college students of Zhuang Nationality.
