Obesity in patients with COPD, an undervalued problem?

1 In their review, the authors use obesity prevalence estimates for COPD patient populations from only two studies with a relatively small sample sizes. 2 3 Therefore, in our view, whether or not obesity is actually more prevalent in patients with COPD is still a matter of debate. [...]the current evidence of a possible association between obesity and a worse COPD disease state is inconclusive. [...]we ask for more attention to be paid to obesity in patients with COPD, in both research and patient care.
