RELATION OF PHYSICAL ACTIVITY AND OBESITY WITH LUNG CAPACITY AMONG ADULT FEMALES
Obesity and poor respiratory function are associated with morbidity and mortality. Obesity affects lung function, however the effects of all degrees of obesity on lung function should be investigated in different populations and gender. Aims and Objectives: The authors investigated the relationship between BMI, waist circumference, physical activity with lung function among adult females. Place and Duration: In the Pulmonology Department of Fauji Foundation Hospital Rawalpindi for one-year
... ion from March 2019 to February 2020. Material and methods: The analysis included 359 women aged 18-44, who had not been diagnosed with any serious disease before, and who had a complete anthropometric examination (height, weight and waist circumference) and forced vital capacity (FVC) using simple measurements spirometry and chest. Physical activity was measured using the "International Physical Activity Questionnaire" (IPAQ). Results: Both FVC and predicted FVC along with the chest dilatation measures were linearly and inversely related across the entire range of body mass index (BMI) and waist circumference (WC) and positively associated with physical activity in subjects, even after adjusting for the confirmatory age our hypothesis. However, BMI and exercise accounted for the highest percentage of variance for both FVC and thoracic expansion in regression analysis compared to WC. Conclusion: In the general population of adult women, obesity may play a role in impaired lung function from a BMI ≥ 35 kg / m2, while even moderate physical activity may have a positive effect on lung function.
