Study Objectives: the association of mild obstructive sleep apnea (OSA) with important clinical outcomes remains unclear. We aimed to investigate the association between mild OSA and systemic arterial hypertension (SAH) in the European Sleep Apnea Database cohort. Methods: in a multicenter sample of 4,732 participants, we analyzed the risk of mild OSA (subclassified into 2 groups: mild(AHI) (5-<)(11)(/h) (apnea-hypopnea index [AHI], 5 to <11 events/h) and mild(AHI) (1)(1-<15/h) (AHI, >= 11 to <15 events/h) compared with nonapneic snorers for prevalent SAH after adjustment for relevant confounding factors including sex, age, smoking, obesity, daytime sleepiness, dyslipidemia, chronic obstructive pulmonary disease, type 2 diabetes, and sleep test methodology (polygraphy or polysomnography). Results: SAH prevalence was higher in the mild(AHI) (11-<15/h) OSA group compared with the mild(AHI 5-<11/h) group and nonapneic snorers (52% vs 45% vs 30%; P < .001). Corresponding adjusted odds ratios for SAH were 1.789 (mild(AHI) (11-<15/h); 95% confidence interval [CI], 1.49-2.15) and 1.558 (mild 1.34-1.82), respectively (P < .001). in sensitivity analysis, mild(AHI) (11-<15/h) OSA remained a significant predictor for SAH both in the polygraphy (odds ratio, 1.779; 95% CI, 1.403-2.256; P < .001) and polysomnography groups (odds ratio, 1.424; 95% CI, 1.047-1.939; P = .025). Conclusions: Our data suggest a dose-response relationship between mild OSA and SAH risk, starting from 5 events/h in polygraphy recordings and continuing with a further risk increase in the 11- to <150-events/h range. These findings potentially introduce a challenge to traditional thresholds of OSA severity and may help to stratify participants with OSA according to cardiovascular risk.
