Caspersen NF, et al. - Researchers looked at the link between circulating adiponectin (ADPN) levels and lung function using multivariate linear regression analyses adjusted for age, gender, height, smoking habits, weight, body mass index, waist-hip ratio, metabolic syndrome, obstructive sleep apnoea (OSA) and C-reactive protein. They hypothesized that ADPN would be associated with lung function in a population-based sample. The impact of abdominal adiposity, metabolic syndrome, and systemic inflammation on this association was also assessed. No association was found between ADPN and lung function was evident after adjustment for covariates related to adiposity. Among co-variates only waist-hip ratio significantly attenuated the relationship.
