Correlation between diaphragmatic thickness and anthropometry in an apparently healthy population

Abstract

Objective: Diaphragmatic thickness is a key indicator of respiratory function, but its relationship with anthropometric variables has not been fully elucidated. This study explored the relationship between diaphragmatic thickness and anthropometric characteristics in young Mexicans, with the aim of improving the understanding of these factors to optimize the clinical evaluation and follow-up of patients at risk of respiratory complications.

Methodology: An exploratory correlational study was conducted with a sample of 64 young Mexicans from the city of Puebla. Anthropometric variables such as BMI, abdominal circumference, and waist-to-height (W/H) and waist-to-hip (WH) ratios were measured. Diaphragmatic thickness was assessed by ultrasound. Statistical analysis included the calculation of the mean, standard deviation, and Pearson's compensation, considering statistical significance with p < 0.05.

Results: The sample consisted of 40 women and 24 men. The average diaphragmatic thickness was 2.33mm±0.63. Pearson correlations showed a low relationship between diaphragmatic thickness and anthropometric variables: BMI (r = 0.0455), waist circumference (r = 0.0322), C/T ratio (r = 0.0377) and CC ratio (r = 0.0005).

Conclusion: The study revealed a low compensation between diaphragmatic thickness and anthropometric variables in young people. These findings suggest that diaphragmatic thickness cannot be fully explained by body anthropometry, highlighting the need for multidimensional approaches in clinical assessment. Future research should explore other factors that may influence diaphragmatic morphology.
