摘要

Study Objectives:

It has been described a bi-directional association between obstructive sleep apnea (OSA) and metabolic syndrome (MetS), both promoting atherosclerosis and cardiovascular disease. Given that cardiometabolic comorbidities associated with OSA tend to diminish with age, in this study we examined whether the association of OSA with MetS is modified by age and body weight.

Methods:

We studied 1,741 adults from the Penn State Adult Cohort (age 20–88 years) who underwent a 1-night polysomnography, clinical history, and physical examination in a cross-sectional design. The presence of OSA was defined as an apnea-hypopnea index ≥ 15 events/h. Outcome variables include the 5 MetS components (obesity [≥ 30kg/m2], hypertension [≥ 130/85 mm Hg], hyperglycemia [fasting blood sugar (FBS) ≥ 100 mg/dL], hypercholesterolemia [≥ 200 mg/dL], and hypertriglyceridemia [≥ 150 mg/dL]). Logistic regression models examined the association of OSA with MetS components adjusting for confounders.

Results:

There was a significant interaction between OSA and age on MetS. In young and middle-aged individuals (< 60 years old) but not in older individuals, OSA was significantly associated with MetS and its individual components, ie, hypertension (odds ratio [OR] = 3.85, 95% confidence interval [CI] = 1.95–7.63), hyperglycemia (OR = 5.62, 95% CI = 2.74–11.53), hypercholesterolemia (OR = 5.99, 95% CI = 2.36–15.21), and hypertriglyceridemia (OR = 4.75, 95% CI = 2.30–9.90). The association of OSA with body mass index was stronger in the young and middle-aged vs older group (OR = 6.03, 95% CI = 3.08–11.78 vs 2.47, 95% CI = 1.23–4.94, respectively). Similar age-related modifications were observed in nonobese individuals.

Conclusions:

The strong association of OSA with MetS in young and middle-aged obese and nonobese adults, but not in older adults, suggests that MetS is key to the pathogenesis of OSA in young and middle-aged adults and should be a treatment priority.
