Why the study?
The relationship between body weight and lung function is complex, prompting investigation into whether more rapid BMI increase correlates with more rapid lung function decline.
Does a more rapid increase in BMI accelerate lung function decline in adults?
Does a more rapid increase in BMI accelerate lung function decline in adults?
Greater rates of weight gain are significantly associated with greater rates of lung function loss over a median follow-up of 19 years.
No takes yet. Share an insight, caveat, or question.
May link faster BMI gain to accelerated lung function loss; leaves open causal effects on FEV1 in observational data.
Schwartz et al. (2024) studied this question.
