Risk of Obstructive Sleep Apnea in Adult Patients with Asthma: A Population-Based Cohort Study in Taiwan.

ABSTRACT: BACKGROUND:There are several publications reported that obstructive sleep apnea (OSA) was associated with asthma. However, large-scaled, population-based cohort study has been limited. We aimed to examine the risk of OSA among adult patients with asthma in an Asian population. METHODS:We conducted a retrospective cohort study using data from the National Health Insurance (NHI) of Taiwan. The asthma cohort included 38,840 newly diagnosed patients between 2000 and 2010. The date of diagnosis was defined as the index date. Each patient was randomly matched with four people without asthma according to gender, age, and the index year as the comparison cohort. The occurrence of OSA was followed up until the end of 2011. The risk of OSA was estimated using the Cox proportional hazard model after adjusting for gender, age, and comorbidities. RESULTS:The overall incidence of OSA was 2.51-fold greater in the asthma cohort than in the comparison cohort (12.1 versus 4.84 per 1000 person-years). Compared to non-asthma subjects, the adjusted hazard ratio (aHR) of OSA increased to 1.78 for asthma patients with one or less annual emergency room (ER) visit, and 23.8 for those who visited ER more than once per year. In addition, aHR in patients with inhaled steroid treatment compared to those without steroid treatment was 1.33 (95% CI = 1.01-1.76). CONCLUSION:Patients with asthma have a significantly higher risk of developing OSA than the general population. The results suggest that the risk of OSA is proportional to asthma control and patients with inhaled steroid treatment have a higher risk for OSA than those without steroid treatment.

Project description:ImportanceObstructive sleep apnea (OSA) is more common among patients with asthma; whether asthma is associated with the development of OSA is unknown.ObjectiveTo examine the prospective relationship of asthma with incident OSA.Design, setting, and participantsPopulation-based prospective epidemiologic study (the Wisconsin Sleep Cohort Study) beginning in 1988. Adult participants were recruited from a random sample of Wisconsin state employees to attend overnight polysomnography studies at 4-year intervals. Asthma and covariate information were assessed during polysomnography studies through March 2013. Eligible participants were identified as free of OSA (apnea-hypopnea index [AHI] of <5 events/h and not treated) by 2 baseline polysomnography studies. There were 1105 4-year follow-up intervals provided by 547 participants (52% women; mean [SD] baseline age, 50 [8] years).ExposuresQuestionnaire-assessed presence and duration of self-reported physician-diagnosed asthma.Main outcomes and measuresThe associations of presence and duration of asthma with 4-year incidences of both OSA (AHI of ≥5 or positive airway pressure treatment) and OSA concomitant with habitual daytime sleepiness were estimated using repeated-measures Poisson regression, adjusting for confounders.ResultsTwenty-two of 81 participants (27% [95% CI, 17%-37%]) with asthma experienced incident OSA over their first observed 4-year follow-up interval compared with 75 of 466 participants (16% [95% CI, 13%-19%]) without asthma. Using all 4-year intervals, participants with asthma experienced 45 cases of incident OSA during 167 4-year intervals (27% [95% CI, 20%-34%]) and participants without asthma experienced 160 cases of incident OSA during 938 4-year intervals (17% [95% CI, 15%-19%]); the corresponding adjusted relative risk (RR) was 1.39 (95% CI, 1.06-1.82), controlling for sex, age, baseline and change in body mass index, and other factors. Asthma was also associated with new-onset OSA with habitual sleepiness (RR, 2.72 [95% CI, 1.26-5.89], P = .045). Asthma duration was related to both incident OSA (RR, 1.07 per 5-year increment in asthma duration [95% CI, 1.02-1.13], P = .01) and incident OSA with habitual sleepiness (RR, 1.18 [95% CI, 1.07-1.31], P = .02).Conclusions and relevanceAsthma was associated with an increased risk of new-onset OSA. Studies investigating the mechanisms underlying this association and the value of periodic OSA evaluation in patients with asthma are warranted.

Project description:ImportanceObstructive sleep apnea (OSA) has been proposed as a risk factor in infertility. However, to date, the association between OSA and male infertility has not been examined in a population-based study.ObjectiveTo investigate the risk factor of OSA in male infertility and the outcome of OSA treatment for the risk of male infertility.Design, setting, and participantsThis case-control population-based study collected data from the Longitudinal Health Insurance Database, a subset of the National Health Insurance Research Database in Taiwan. Male patients with a diagnosis of infertility and at least 3 outpatient visits or 1 hospitalization between January 1, 2000, and December 31, 2013, were included and matched by age, sex, and date of infertility diagnosis with individuals without an infertility diagnosis. Data analysis was performed from October 22, 2018, to April 22, 2019.ExposuresPatients with male infertility and randomly selected patients without male infertility were matched using a 1:4 propensity score matching ratio.Main outcomes and measuresA primary outcome was the risk factor of OSA (diagnosed through polysomnography). A secondary outcome was the association of the risk of male infertility with OSA exposure time interval (short term, middle term, and long term) and OSA management (ie, none, continuous positive airway pressure, uvulopalatopharyngoplasty, or both).ResultsA total of 4607 male patients with infertility (mean [SD] age, 34.18 [5.44] years) and 18 428 control patients (mean [SD] age, 34.28 [5.81] years) were included. In the multivariate conditional logistic regression analysis, OSA was an independent risk factor associated with infertility (adjusted odds ratio [OR], 1.24; 95% CI, 1.10-1.64; P = .003). The absolute risk was 0.204 (95% CI, 0.092-0.391). For patients with OSA in the group without treatment, the adjusted OR was 1.80 (95% CI, 1.56-2.07; P < .001) for infertility compared with patients without OSA.Conclusions and relevanceResults of this study support the hypothesis that OSA increases the risk of infertility in male patients, and the risk is associated with the OSA exposure time. Furthermore, no OSA management or treatment is associated with a higher infertility risk.

Project description:Studies have shown a higher risk of depressive disorders in children with sleep apnea than in those without sleep apnea. However, the association between sleep apnea and subsequent depressive disorders in the pediatric population remains undetermined. Thus, this study investigated the risk of depressive disorders among pediatric patients with sleep apnea.In this study, the population-based National Health Insurance Research Database of Taiwan was used to identify patients who had first been diagnosed with sleep apnea between 1999 and 2013. Patients with sleep apnea who were younger than 18 years were included in the sleep apnea group. Controls (those without sleep apnea) were matched to patients with sleep apnea at a 1:10 ratio by age, sex, and index year. Patients who had baseline or inherited depressive disorders before the enrollment date were excluded. The two groups were followed up until December 31, 2013. The primary endpoint was the occurrence of one or more depressive disorders.At the end of this study, 6,237 children had been enrolled, comprising 567 children with sleep apnea and 5,670 children without sleep apnea. During the mean follow-up period of 5.87 years, a total of 77 children (1.23%) developed one or more depressive disorders; 14 (2.46%) from the sleep apnea group and 63 (1.11%) from the control group. Kaplan-Meier analysis showed that children with sleep apnea had a significantly higher risk of depressive disorders (log-rank test, p = 0.002). After adjusting for covariates, the risk of subsequent depressive disorders among children with sleep apnea was still significantly higher (hazard ratio [HR] = 2.25; 95% confidence interval [CI] = 1.25-4.05; p = 0.006). Moreover, boys with sleep apnea had a significantly higher risk than those without sleep apnea (adjusted HR = 3.77; 95% CI, 1.82-7.54; p < 0.001). Furthermore, in sleep apnea group, children older than 12 years of age had more risk to depression (hazard ratio (HR) = 7.1833, 95% confidence interval (CI), 2.3734 to 21.7411; p = 0.0004).This study found a significantly higher subsequent risk of depressive disorders in children with sleep apnea, particularly boys and those older than 12 years of age. The study findings strongly suggest that clinicians should provide psychological evaluation and supportive care for children with sleep apnea, in addition to medical treatment.
