Abstract

Purpose: The correlation between body weight and health is a significant public health concern. While the adverse effects of obesity on pulmonary function are well-known, the impact of being underweight remains debated due to limited research. This study aimed to investigate the correlation between Body Mass Index (BMI) categories and lung function parameters.

Results: A study of 3077 participants found significant differences in gender, age, height, and weight across various Body Mass Index (BMI) categories. The study found non-significant variations in forced expiratory flow (FVC) across BMI categories, with underweight individuals showing lower FVC compared to normal and overweight individuals. BMI significantly impacted mean forced expiratory flow during the middle half of FVC. A significant negative correlation was observed between age and FVC, FEV1, FEV1/FVC ratio, and FEF25-75. A significant positive correlation was observed between weight, height, and lung function parameters. Multiple regression analysis revealed a decrease in lung function with advancing age, while height showed significant positive associations. The study concluded that age, sex, smoking, height, and weight collectively explained 41.0% of the variance in FVC, FEV, and FEF25-75.

探索体重指数与肺功能测试参数之间的相关性：一项横断面分析研究。

目的：体重与健康之间的关系是一个重要的公共卫生问题。虽然肥胖对肺功能的不利影响众所周知，但由于研究有限，对体重不足的影响仍存在争议。本研究旨在调查身体质量指数（BMI）类别与肺功能参数之间的相关性：一项针对 3077 名参与者的研究发现，不同体重指数（BMI）类别的参与者在性别、年龄、身高和体重方面存在显著差异。研究发现，不同体重指数类别的患者用力呼气流量（FVC）差异不大，与正常人和超重者相比，体重不足者的用力呼气流量较低。体重指数对 FVC 中半段的平均用力呼气流量有明显影响。年龄与 FVC、FEV1、FEV1/FVC 比率和 FEF25-75 之间存在明显的负相关。体重、身高和肺功能参数之间呈明显的正相关。多元回归分析显示，肺功能随着年龄的增长而下降，而身高则显示出显著的正相关。研究认为，年龄、性别、吸烟、身高和体重共同解释了 41.0% 的 FVC、FEV 和 FEF25-75 变异。
