Sleep disordered breathing: prevalence and association with cardiovascular disease in the French general population

Abstract Background Sleep Disordered Breathing (SDB) is highly prevalent and associated with cardiovascular disease (CVD) but many studies have a limited sample size or uncertain generalizability. Purpose The aim of this study was to obtain contemporary data on SDB prevalence and to assess its impact on CVD occurrence in a large French population-based sample. Methods Data came from participants of the French population-based CONSTANCES cohort, included between 2012 and 2016, with clinical interview, examination and standard biology at inclusion and who were screened for SDB in 2017 using the Berlin Questionnaire (BQ). Follow-up was performed through yearly CONSTANCES questionnaires. CVD occurrence was defined by self-declared myocardial infarction or stroke between 2013 and 2017. Exposure variables were SDB diagnosis on the basis on BQ and its related sleeping symptoms (snoring, apnea and sleepiness). Odds Ratios (OR) were computed with their 95% Confidence Interval (95% CI) and adjusted for age, sex, smoking, dyslipidemia, diabetes, hypertension and body mass index (except for SDB since BQ considers these variables). Results Among 54 228 participants, SDB prevalence was 16.1%. Over four years of follow-up, CVD occurred in 2.23% of SDB participants vs 0.72% in non SDB (OR=1.72, 95% CI [1.41–2.09]). CVD occurrence did not increase significantly with snoring (OR=0.95, 95% CI [0.78; 1.17]), but with apnea (OR=1.34, 95% CI [1.05; 1.71]) and with sleepiness (OR=1.42, 95% CI [1.18–1.72] when fatigue occurred after-sleep and OR=1.62, 95% CI [1.33–1.97] during waking time). These associations remained non-significant for snoring regardless of its frequency or noise, were significant for sleepiness as soon as it happened at least once a week and tended to increase with its frequency whenever fatigue occurred (p for trend<0.001). Subgroups analysis in hypertensive and non-hypertensive participants found similar results concerning snoring and sleepiness. Conclusions These results confirm that SDB is highly prevalent in the general French population and is associated with a higher occurrence of CVD particularly in sleepy and apneic subjects. Screen for SDB and its symptoms should be relevant to identify high cardiovascular risk people who would benefit from preventive measures.

Objectives: To study the epidemiology of sleep-disordered breathing (SDB) in adolescents, which has received little attention. Methods: The Penn State Child Cohort (PSCC) is a representative general population sample of 700 children aged 5-12 years. Our preliminary results are based on an average 8 year follow up of the initial 300 prospective subjects (~43%) from this ongoing cohort study. A logistic regression was used to assess the association between potential risk factors and incident SDB. Results: The mean age at the 8-year follow up examination was 17.2 ± 0.1 years, with an average BMI percentile of 66.6 ± 1.6 and 56.5% boys. At baseline 1.5% of this subsample had SDB, defined by Apnea Hypopnia Index (AHI > 5 /hour). Surprisingly, there was no persistence of SDB. Eight-year incident SDB was 10.5%. The average AHI in those with incident SDB was 12.7 with a maximum of 92.4. Incident SDB was similar for girls (7.8%) and boys (12.7%). Those with SDB were older than those without (18.7 vs 17.0 years, P<0.001) and girls with SDB were older than boys with SDB (20.0 vs 18.0 years, P=0.002). Those with incident SDB tended to have a greater change in BMI percentile (8.2 vs 1.8, P = 0.143) during the follow up and slightly higher minority representation (25.8% vs 21.9%, P=0.655). A logistic regression model identified three variables that were associated with incident SDB, controlling for baseline AHI: age (OR = 1.5 (1.3, 1.9) P<0.001), male (OR= 2.5 (1.11,10.00) P=0.021), and [[Unable to Display Character: ∆]]BMIPCT (OR=1.2(1.02, 1.5) P=0.032). Conclusion: In this population based sample of adolescents, the 8-year incidence of SDB was high (10.5%), whereas childhood SDB did not persist into adolescence. Further, the results indicate that risk factors for incident SDB in adolescents are age, male and the development of obesity.

Disordered Breathing

Background: Sleep-disordered breathing (SDB) is an independent risk factor for stroke. The reported prevalence of SDB after stroke ranges from 60 to >70%, while the pre-stroke prevalence of SDB is less well described. Moreover, much of these data are derived from ischemic stroke or mixed ischemic stroke and intracerebral hemorrhage (ICH) cohorts. Studies that assess the prevalence of SDB before and after ICH are lacking, with only one prior study (n=32) that reported a post-ICH SDB prevalence of 78%. We report herein the results of a second, larger, prospective study that assessed the prevalence of pre- and post-ICH. Methods: Participants enrolled in the population-based stroke surveillance study, the Brain Attack Surveillance in Corpus Christi (BASIC) project, with ICH from 2010-2015 were screened for SDB with the well validated ApneaLink Plus portable monitor (SDB defined as apnea-hypopnea index (AHI) ≥10). The Berlin questionnaire was administered, with reference to the pre-ICH state, to assess for possible pre-stroke SDB. Results: Of the 60 ICH participants screened, the median age was 63 years (interquartile range (IQR): 55.5, 74.5). Twenty-one (35%) were female, 54 (90%) were Mexican American, and 53 (88%) had a history of hypertension. The median Glasgow Coma Scale score was 15.0 (IQR: 15.0, 15.0) and the median NIHSS was 5.5 (IQR: 1.5, 8.0). Post-ICH, the median AHI was 9.5 (IQR: 5.5, 19.0); almost half (46.7%) met criteria for SDB. Thirty-four participants (56.7%) screened as high risk for SDB pre-ICH. Conclusion: Sleep-disordered breathing was highly prevalent after ICH, and also likely common before ICH, in this mostly Mexican American, community-based sample. If SDB increases risk for ICH, the findings suggest a potential new treatment target to prevent ICH and recurrent ICH.

Disordered Breathing

Objectives: To examine the association between incident sleep-disordered breathing (SDB) and blood pressure and blood pressure reactivity in a population based sample of adolescents. Methods: The Penn State Child Cohort is a general population based sample of 700 children aged 5-12 years at the baseline examination (2000-2005). Currently, 300 participants have completed their 8-year follow up examination. Blood pressure was assessed at follow up in the evening using an automated device prior to the sleep recording in three positions. Three assessments in the seated position were completed after 5 minutes of rest. This was followed by 3 assessments in the supine position after 5 minutes of rest. The averages of the 2 nd and 3 rd readings for both positions are reported. Finally the subject was asked to stand as fast as possible and 2 additional readings were completed immediately upon their foot hitting the floor. These two standing readings were averaged. The difference between standing and supine BP was used as measures of vascular reactivity. The age, gender and height adjusted mean level of BP measures comparing individuals with and without incident SDB (defined as Apnea Hypopnia Index, AHI>5/hr) after excluding individuals with baseline SDB were calculated. Results: We observed no significant differences in diastolic blood pressure across the three positions. However, systolic blood pressure across all three positions and vascular reactivity were significantly elevated in those with incident SDB, as summarized in Table 1. Conclusion: In an 8-year followup of this population based sample of children, there was no persistence of SDB from baseline. Incident SDB (about 11%) was significantly associated with elevated systolic BP across all three positions. Further, SDB was associated with increased systolic BP reactivity, which has been associated with increased risk of CVD and the development of hypertension in adults.

Abstract Background Preterm birth (gestational age <37 weeks) has previously been associated with cardiometabolic and neuropsychiatric disorders into adulthood, but has seldom been examined in relation to sleep disorders. We conducted the first population-based study of preterm birth in relation to sleep-disordered breathing (SDB) from childhood into mid-adulthood. Methods A national cohort study was conducted of all 4 186 615 singleton live births in Sweden during 1973–2014, who were followed for SDB ascertained from nationwide inpatient and outpatient diagnoses through 2015 (maximum age 43 years). Cox regression was used to examine gestational age at birth in relation to SDB while adjusting for other perinatal and maternal factors, and co-sibling analyses assessed for potential confounding by unmeasured shared familial factors. Results There were 171 100 (4.1%) persons diagnosed with SDB in 86.0 million person-years of follow-up. Preterm birth was associated with increased risk of SDB from childhood into mid-adulthood, relative to full-term birth (39–41 weeks) [adjusted hazard ratio (aHR), ages 0–43 years: 1.43; 95% confidence interval (CI), 1.40, 1.46; P <0.001; ages 30–43 years: 1.40; 95% CI, 1.34, 1.47; P <0.001]. Persons born extremely preterm (<28 weeks) had more than 2-fold risks (aHR, ages 0–43 years: 2.63; 95% CI, 2.41, 2.87; P <0.001; ages 30–43 years: 2.22; 95% CI, 1.64, 3.01; P <0.001). These associations affected both males and females, but accounted for more SDB cases among males (additive interaction, P = 0.003). Co-sibling analyses suggested that these findings were only partly due to shared genetic or environmental factors in families. Conclusions Preterm-born children and adults need long-term follow-up for anticipatory screening and potential treatment of SDB.

Disordered Breathing

Introduction: Sleep-disordered breathing (SDB) is common after stroke and is associated with poor functional and cognitive outcomes, and recurrent stroke. Despite increasing prevalence of SDB in the general population, no data are available about trends in post-stroke SDB. We therefore sought to assess changes in post-stroke SDB prevalence over a 10-year period. Methods: Within the Brain Attack Surveillance In Corpus Christi (BASIC) project, a population-based stroke surveillance study in south Texas, participants with acute ischemic stroke were offered assessment of SDB with the ApneaLink Plus device. Medical record abstraction and baseline interviews were conducted and included the Berlin questionnaire to assess SDB status in reference to the prestroke state. SDB testing was performed shortly after stroke presentation (median 12 days (IQR: (6, 21)). Respiratory event index (REI) was calculated as the sum of apneas and hypopneas per hour of overnight recording. SDB was defined as an REI ≥10. SDB assessment procedures remained unchanged throughout (2010-2020). Logistic (SDB) and linear (REI) regression were used to test associations with time (parameterized as years since 2010) adjusted for demographics, and stroke and SDB risk factors including BMI and pre-stroke SDB status. Results: Among the 1,197 participants, median age was 65, 53% were male, and 65% were Mexican American. SDB prevalence was 61% in 2010-2011 and 75% in 2018-2019. Median REI was 19 in 2010-2011 and 23 in 2018-2019. A linear association was identified between time and SDB (REI≥10), with an odds ratio of 1.123 (95% CI: 1.062, 1.187) per year, after adjustment. Similarly, a linear association was identified between time and REI, with an average increase of 0.504 (95% CI: 0.148, 0.860) per year, after adjustment. Based on models with interaction terms added, no differences in time trends were found by sex or ethnicity. Conclusions: Post-stroke SDB prevalence in this population-based sample has increased over the last 10 years. These data highlight the importance of post-stroke SDB and the pressing need to determine whether its treatment improves outcomes.

Objective To assess the impact of rural-urban residence on children with obstructive sleep-disordered breathing (SDB) who were candidates for tonsillectomy with or without adenoidectomy (TA). Study Design Retrospective cohort study. Setting Tertiary children’s hospital. Methods A cohort of otherwise healthy children aged 2 to 18 years with a diagnosis of obstructive SDB between April 2016 and December 2018 who were recommended TA were included. Rural-urban designation was defined by ZIP code approximation of rural-urban commuting area codes. The main outcome was association of rurality with time to TA and loss to follow-up using Cox and logistic regression analyses. Results In total, 213 patients were included (mean age 6 ± 2.9 years, 117 [55%] male, 69 [32%] rural dwelling). Rural-dwelling children were more often insured by Medicaid than private insurance ( P < .001) and had a median driving distance of 74.8 vs 16.8 miles ( P < .001) compared to urban-dwelling patients. The majority (94.9%) eventually underwent recommended TA once evaluated by an otolaryngologist. Multivariable logistic regression analysis did not reveal any significant predictors for loss to follow-up in receiving TA. Cox regression analysis that adjusted for age, sex, insurance, and race showed that rural-dwelling patients had a 30% reduction in receipt of TA over time as compared to urban-dwelling patients (hazard ratio, 0.7; 95% CI, 0.50-0.99). Conclusion Rural-dwelling patients experienced longer wait times and driving distance to TA. This study suggests that rurality should be considered a potential barrier to surgical intervention and highlights the need to further investigate geographic access as an important determinant of care in pediatric SDB.

Abstract Background/Introduction Limited real-world data are available on attainment of low-density lipoprotein cholesterol (LDL-C) treatment goals in patients with atherosclerotic cardiovascular disease (ASCVD) in Canada. Purpose A retrospective observational study was conducted to describe types of ASCVD events/procedures, time between events and use of lipid lowering treatment (LLT) in patients who did not achieve LDL-C goal. Methods Patients in Ontario ≥65 years with a primary ASCVD event/procedure between 1 Apr 2005 and 31 Mar 2016, treated with an LLT and with index and follow up LDL-C values were identified from claims data at the Institute for Clinical Evaluative Sciences data repository. Patients were assessed over a 1-year follow up period for LDL-C goal attainment (<2.0 mmol/L or 50% reduction from index LDL-C) and analysed by LLT and by index event type. Results Overall, 28% of 143,302 patients ≥65 years on LLT failed to attain LDL-C goal at follow up (Figure). The proportion of patients failing to achieve LDL-C goal decreased from 35% to 22% over the 11-year study period. Mean time between index and follow up LDL-C (based on lowest score >2 weeks and up to 1 year after index LDL-C) was 203±97 days. When analysed by low-, moderate- or high-intensity statin, 57%, 30%, and 22% of patients failed to achieve LDL-C goal at follow up, respectively. Conclusions In this study, more than 1 in 4 patients with ASCVD in Ontario failed to achieve guideline recommended LDL-C goal despite treatment. In particular, ∼1 in 3 patients with cerebral and peripheral arterial disease were not at goal. An opportunity exists to better manage these high risk ASCVD patients with further statin intensification and additional LLTs This study made use of de-identified data from the ICES Data Repository, which is managed by the Institute for Clinical Evaluative Sciences with support from its funders and partners: Canada's Strategy for Patient-Oriented Research (SPOR), the Ontario SPOR Support Unit, the Canadian Institutes of Health Research and the Government of Ontario.
