Big waist size linked to decreased lung function

[Source: ScienceDaily] – There’s more bad news for people who carry excess weight around their waists: Not only is abdominal obesity associated with diabetes, hypertension, cardiovascular disease and a host of other health problems collectively known as “metabolic syndrome,” a new study has found that a high waist circumference is strongly associated with decreased lung function—independent of smoking history, sex, body mass index (BMI) and other complicating factors.

The study analyzed health information on more that 120,000 people from the Paris Investigations Preventives et Cliniques Center, and assessed demographic background, smoking history, alcohol consumption, as well as lung function, including FEV1 (forced expiratory volume in one second) and FVC (forced vital capacity, or the total expiratory volume) with respect to BMI, waist circumference and other measures of metabolic health.

The results were published in the second issue for March of the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
