Abstract
Background and aim: Obesity is considered a challenging problem in all age groups, especially in children and adolescents. In various epidemiological studies, high Body Mass Index (BMI), waist circumference, and Waist-to-Hip Ratio (WHR) have been identified as risk factors for many chronic diseases, including respiratory diseases. Among these, waist circumference and Waist-to-Hip Ratio are important parameters for identifying central obesity. Our aim is to determine the correlation between Peak Expiratory Flow Rate(PEFR) and anthropometric parameters, including height, weight, BMI, and Waist-Hip Ratio.
Material and methods: A cross-sectional study was conducted among 102 medical students to assess the effects of height, weight, BMI, Waist circumference, and Waist-to-Hip Ratio (WHR) on PEFR. All subjects were informed about the study, and a demonstration of the procedure was provided. Height, weight, waist circumference, and hip circumference were recorded. WHR and BMI were calculated. BMI was derived using Quetlet’s index. PEFR was recorded using Wright’s peak flow meter. Data was collected and analyzed using SPSS. Pearson correlation was used for data analysis.
Results: The present study showed negative correlations between weight, BMI, waist circumference, and WHR and PEFR. The correlation between WHR and PEFR was not significant. It also showed a positive correlation between height and PEFR.
Conclusions: Our study found that height, weight, BMI, and waist circumference affect PEFR values. Among those, increased adiposity, BMI, waist circumference, and Waist-to-Hip Ratio are associated with lower PEFR. PEFR values are higher in people with increased height.
