Abstract
OBJECTIVE: We aimed to provide a more precise estimate of the relationship between telomere length and obstructive sleep apnea (OSA) by systematically reviewing evidence. METHOD: We conducted a systematic electronic search in the databases of the PUBMED, PsycINFO, OVID (Medline), EMBASE and other resources (such as Google Scholar). The methodological quality of the articles was assessed according to the Newcastle Ottawa Scale. Heterogeneity was assessed using the chi-square test for Cochrane's Q statistic and I-squared. When heterogeneity was found to be reasonably high between studies, the random-effects model with the mean difference (95% confidence interval [CI]) was conducted using RevMan 5 software by using the inverse variance method (P < 0.05; chi-square test). By contrast, the fixed-effects model was carried out. RESULTS: Eight eligible studies involving 2639 participants were included in our meta-analysis. Shortened telomere length was significantly associated with OSA with mean difference of -0.03 (95% CI: -0.06, -0.00; P = 0.003 with I-square of 85%）. The results of subgroup analysis preformed by age and sample number suggested that shorter telomere length was significantly associated with OSA, with mean difference of -0.07 (95% CI: -0.07, -0.01; P = 0.005) for adult group and -0.04 (95% CI: -0.02, -0.06; P = 0.005) for large-sample studies. CONCLUSION: Compared to healthy people, individuals with OSA have shorter telomere lengths which implicates early intervention and timely treatment for preventing future adverse outcomes.
