# Fibular length and vital capacity in the multinational Burden of Obstructive Lung Disease follow-up study

## TL;DR

This study examines how leg length and total height relate to lung function, finding little association in a multinational sample.

## Contribution

The study provides new multinational evidence that long bone length has a small and non-significant association with vital capacity.

## Key findings

- The association between long bone length and vital capacity was consistently small.
- No significant relationship was found between leg length and forced vital capacity across multiple countries.

## Abstract

The relative association of leg length and total height on lung volumes may be important for the clinical assessment of forced vital capacity (FVC) and for understanding critical periods in lung development. The expected size of the FVC in a healthy person generally takes account of their age, sex and size. Most commonly, size has been assessed as standing height or standing height squared. Louw
et al. [1] suggested that sitting height gave a better assessment of lung function than standing height. Harik-Khan
