Relationship between body fat percentage and forced vital capacity in adults with normal body mass index

Lung function tests are widely used to evaluate lung health conditions, and measuring the forced vital capacity is a major tool in this field. The impact of body fat percentage on lung function has rarely been evaluated. This study aimed to evaluate the relationship between body fat percentage and forced vital capacity. This was a cross-sectional study using 62 subjects who were identified from secondary data and selected by simple random sampling. Data were analyzed using the Kolmogorov-Smirnov normality test and the Pearson correlation test. This study found no correlation between body fat percentage and forced vital capacity, as measured by p > 0.001, for both male and female groups. Thus, the study revealed no significant correlation between body fat percentage and forced vital capacity.
