There is no evidence that growth stunting due to poor SES is limited to height, so it is logical to assume that chest dimensions will also be affected. If poor SES leads to a 1%, 2% or 3% lower width, depth and height of the thoracic cage, this leads to a 3%, 6% and 9% lower volume of the chest cavity, respectively. Taking into account measurement error and individual variability, it will be difficult to assess such small differences, but they cannot be discarded and might (in part) explain the observed difference in growth of FEV1. Measurements of chest circumference in a large number of subjects might throw some light on the role of differences in body frame. It is bold to disregard the potential role of poor socioeconomic status in lung function over decades of adult life http://ow.ly/DW6kn ER -
