Examining the association between obstructive sleep apnea and cardiometabolic risk factors in the elderly

Obstructive sleep apnea (OSA) and metabolic syndrome (MetS) are common chronic disorders associated with cardiovascular morbidity and mortality. The goal of our research is to identify the associations between OSA and MetS, including different components of MetS, in adults.
We used data from the 2007–2008 National Health and Nutrition Examination Survey, which included 5909 eligible subjects (2898 men, 3011 women), aged 20 and over, who had undergone a complete medical examination and had self-reported three OSA symptom items. The primary study outcome was possible obstructive sleep apnea (pOSA) and MetS components.
Participants in the pOSA group had significantly more MetS components (p < 0.001). In the group aged ≥ 60 years, there was a stronger relationship between pOSA and MetS components. After additional adjustment, the odds ratios for pOSA among those with 2, 4, and 5 MetS components were 3.11, 3.19, and 4.89, respectively (p < 0.05).
In conclusion, our study indicates that the risk of pOSA is higher in association with increased MetS factors, particularly among the elderly. Leading a healthy lifestyle may help reduce OSA risk in elderly patients with MetS.
