Sleep-disordered breathing in a population-based cohort: behavioral outcomes at 4 and 7 years.

ABSTRACT:

Objectives

Examine statistical effects of sleep-disordered breathing (SDB) symptom trajectories from 6 months to 7 years on subsequent behavior.

Methods

Parents in the Avon Longitudinal Study of Parents and Children reported on children's snoring, mouth breathing, and witnessed apnea at ?2 surveys at 6, 18, 30, 42, 57, and 69 months, and completed the Strengths and Difficulties Questionnaire at 4 (n = 9140) and 7 (n = 8098) years. Cluster analysis produced 5 "Early" (6-42 months) and "Later" (6-69 months) symptom trajectories ("clusters"). Adverse behavioral outcomes were defined by top 10th percentiles on Strengths and Difficulties Questionnaire total and subscales, at 4 and 7 years, in multivariable logistic regression models.

Results

The SDB clusters predicted ?20% to 100% increased odds of problematic behavior, controlling for 15 potential confounders. Early trajectories predicted problematic behavior at 7 years equally well as at 4 years. In Later trajectories, the "Worst Case" cluster, with peak symptoms at 30 months that abated thereafter, nonetheless at 7 years predicted hyperactivity (1.85 [1.30-2.63]), and conduct (1.60 [1.18-2.16]) and peer difficulties (1.37 [1.04-1.80]), whereas a "Later Symptom" cluster predicted emotional difficulties (1.65 [1.21-2.07]) and hyperactivity (1.88 [1.42-2.49]) . The 2 clusters with peak symptoms before 18 months that resolve thereafter still predicted 40% to 50% increased odds of behavior problems at 7 years.

Conclusions

In this large, population-based, longitudinal study, early-life SDB symptoms had strong, persistent statistical effects on subsequent behavior in childhood. Findings suggest that SDB symptoms may require attention as early as the first year of life.

Project description:ObjectiveTo examine the association between sleep-disordered breathing and stroke outcomes, and determine the contribution of sleep-disordered breathing to outcome disparities in Mexican Americans.MethodsIschemic stroke patients (n = 995), identified from the population-based Brain Attack Surveillance in Corpus Christi Project (2010-2015), were offered participation in a sleep-disordered breathing study including a home sleep apnea test (ApneaLink Plus). Sleep-disordered breathing (respiratory event index ≥10) was determined soon after stroke. Neurologic, functional, cognitive, and quality of life outcomes were assessed at 90 days poststroke. Regression models were used to assess associations between sleep-disordered breathing and outcomes, adjusted for sociodemographics, prestroke function and cognition, health-risk behaviors, stroke severity, and vascular risk factors.ResultsMedian age was 67 years (interquartile range [IQR] = 59-78); 62.1% were Mexican American. Median respiratory event index was 14 (IQR = 6-25); 62.8% had sleep-disordered breathing. Sleep-disordered breathing was associated with worse functional outcome (mean difference in activities of daily living/instrumental activities of daily living score = 0.15, 95% confidence interval [CI] = 0.01-0.28) and cognitive outcome (mean difference in modified Mini-Mental State Examination = -2.66, 95% CI = -4.85 to -0.47) but not neurologic or quality of life outcomes. Sleep-disordered breathing accounted for 9 to 10% of ethnic differences in functional and cognitive outcome and was associated with cognitive outcome more strongly for Mexican Americans (β = -3.97, 95% CI = -6.63 to -1.31) than non-Hispanic whites (β = -0.40, 95% CI = -4.18 to 3.39, p-interaction = 0.15).InterpretationSleep-disordered breathing is associated with worse functional and cognitive function at 90 days poststroke. These outcomes are reasonable endpoints for future trials of sleep-disordered breathing treatment in stroke. If effective, sleep-disordered breathing treatment may somewhat lessen ethnic stroke outcome disparities. ANN NEUROL 2019;86:241-250.

Project description:Study objectivesSleep disordered breathing is associated with cardiovascular disease. The pathophysiologic mechanisms remain unclear, but enhanced vascular inflammation is implicated. We sought to evaluate the association of sleep disordered breathing with biomarkers of inflammation.DesignCross-sectional, observational.SettingCommunity-based.ParticipantsThere were 900 participants from the Framingham Heart Study site of the Sleep Heart Health Study (52% females, mean age 60 y, 23% ethnic minorities).InterventionsNone.MeasurementsWe assessed circulating levels of nine inflammatory biomarkers in relation to polysomnographically-derived apnea-hypopnea index and hypoxemia index (% sleep time with oxyhemoglobin saturation < 90%). Multivariable models were adjusted for demographics, smoking, cardiovascular diseases, diabetes, and other potential confounders, without and with adjustment for body mass index.ResultsWith multivariable adjustment not including body mass index, the apnea-hypopnea index was associated with C-reactive protein, inter-leukin-6, fibrinogen, intercellular adhesion molecule-1, and P-selectin levels and hypoxemia index was associated with C-reactive protein, interleukin-6, and fibrinogen levels. After adjustment for body mass index, only the association of interleukin-6 with sleep disordered breathing remained significant: the adjusted mean serum interleukin-6 level was 2.93, 3.14, 3.34, and 4.62 pg/mL, respectively, in participants with apnea-hypopnea index < 5, 5-14.9, 15-29.9, and ? 30 events/h (P = 0.01 for trend) and 2.97, 3.01, 3.35, and 4.85 pg/mL, respectively, in participants with hypoxemia index < 0.5, 0.5-4.9, 5-9.9, and ? 10% of sleep time (P = 0.02 for trend).ConclusionsIn a community-based sample, sleep disordered breathing is associated with higher levels of interleukin-6, a marker of myocardial infarction risk and mortality. Adiposity may mediate the increased levels of C-reactive protein, fibrinogen, intercellular adhesion molecule-1, and P-selectin observed in sleep disordered breathing.

Project description:Background/objectivesSleep-disordered breathing (SDB) has been associated with neurocognitive and behavioral problems in young children; however, this association is less studied in adolescents. Evidence suggests that obesity plays a key role in the development of SDB, although its relative association with neurobehavioral functioning remains unclear. We examined whether SDB and obesity are associated with neurocognitive and behavioral problems in adolescents.Subjects/methodsA total of 421 adolescents (17.0±2.2y, 53.9% male) from the Penn State Child Cohort, a general population sample, underwent a 9-h polysomnography, clinical history, physical examination, neurocognitive evaluation and Dual-energy X-ray Absorptiometry (DXA) scan, and completed the Child or Adult Behavior Checklist. Obstructive sleep apnea (OSA) was defined as an apnea-hypopnea index (AHI)⩾2, primary snoring (PS) as AHI<2+snoring and no-SDB as AHI<2 without snoring. Body weight measures included body mass index (BMI) percentile, waist circumference (WC) and DXA-measured total adipose tissue (TAT).ResultsWC and TAT were significantly associated with impaired vigilance, processing speed, working memory, and control interference and greater internalizing and externalizing behaviors, while BMI percentile was marginally associated. SDB per se (PS, AHI or OSA) was not significantly associated with impaired neurocognitive outcomes or greater behavioral problems. However, TAT was significantly associated with impaired vigilance and greater internalizing and externalizing behaviors and, to a lesser extent, slower processing speed and greater control interference, only in adolescents with OSA.ConclusionsCentral obesity, an etiopathogenic mechanism of OSA, is more strongly associated with neurocognitive and behavioral problems in adolescents than SDB alone. Deficits in low-order (vigilance) and high-order (executive) functions and behavioral problems observed in adolescents with OSA are primarily associated with increased central adiposity, a finding not entirely captured with less precise measures of obesity. These data support that OSA and its associated neurocognitive and behavioral morbidity are related to underlying metabolic dysfunction as early as adolescence.
