Relationship between body composition and pulmonary function in the general population-a cross-sectional study in Ningxia.

ABSTRACT: Studies considering the relationship between non-obesity-related body composition and lung function are few; therefore, this study aimed to explore these correlations and effects. This cross-sectional study conducted in rural Qingtongxia City and Pingluo County, Ningxia, China, included 776 participants aged 30-75 years. Body composition and lung function were measured using direct segmental multifrequency bioelectrical impedance analysis and a digital spirometer, respectively. Their correlation was assessed using partial correlation analysis, controlling for age and smoking status, and the body composition effect on lung function was analyzed using binomial logistic regression analysis. The body components total body water content, protein content, mineral content, muscle mass, fat-free mass (FFM), skeletal muscle mass, basal metabolic volume, and chest circumference (CC) positively correlated with pulmonary function (forced vital capacity and forced expiratory volume in one second) in both sexes. Neck circumference and hip circumference positively correlated with pulmonary function in women. Additionally, lung function declines more slowly in women (odds ratio [OR] = 0.66, 95% confidence interval [CI] = 0.44-0.98, p = 0.04); CC (OR = 0.92, 95% CI = 0.86-0.98, p = 0.01) increased as a protective factor for decreased lung function. Increased waist circumference (OR = 1.04, 95% CI = 1.00-1.09, p = 0.04) was a risk factor for reduced lung function. FFM contains body composition indicators positively correlating with lung function, excluding fat-related body composition. Abdominal obesity increases the risk of decreased lung function.

Project description:Background/objectivesThere is currently limited understanding of the intricate dynamics between fat and muscle mass and the potential effect of dietary patterns. This study aimed to investigate the effects of overall dietary patterns on four body composition phenotypes associated with central obesity and low muscle mass in the middle-aged and elderly population of Korea.MethodsWe examined data from 6120 adults aged ≥ 50 years, collected during the 4th (2008-2009) and 5th (2010-2011) Korea National Health and Nutrition Examination Survey. Participants were classified into four groups according to their combined status of central obesity and low muscle mass: healthy control, central obesity, low muscle mass, and sarcopenic obesity. Using factor analysis on the twenty-two pre-defined food groups, we identified three distinct dietary patterns: the "Healthy dietary pattern", "Convenience-based dietary pattern", and "Alcohol and side dish pattern". Multivariate analysis included potential confounders such as age, sex, place of residence, marital status, educational level, occupation, household income, and physical activity level.ResultsHigher scores in the "Healthy dietary pattern" were associated with lower odds of sarcopenic obesity (OR = 0.61, 95% CI = 0.40-0.92, p for trend = 0.018). For the "Convenience-based dietary pattern", individuals in the third tertile of the dietary pattern score showed a marginal association with low muscle mass (OR = 1.18, 95% CI = 0.99-1.41, p for trend = 0.056). The "Alcohol and side dish pattern" was linked to higher odds of central obesity (OR = 1.22, 95% CI = 1.03-1.44, p for trend = 0.016) and low muscle mass (OR = 1.21, 95% CI = 1.01-1.45, p for trend = 0.043).ConclusionsThe drinking practice of consuming foods high in saturated fats and salt alongside alcoholic drinks may negatively affect fat accumulation and muscle composition among older adults. Adopting a healthy eating pattern characterized by grains, vegetables, legumes, fruits, fish, and seaweed could be notably advantageous for promoting and maintaining healthy body composition and optimal skeletal muscle health.
