Impact of Sleep-Disordered Breathing Treatment on Quality of Life Measures in a Large Clinic-Based Cohort.

ABSTRACT:

Study objectives

This study aims to report the effect of positive airway pressure (PAP) therapy on quality of life (QoL) measures in the clinical sleep-disordered breathing (SDB) population.

Methods

We examined general QoL measures assessed by European Quality of Life-5D (EQ-5D) and sleep-specific QoL by examining Functional Outcomes of Sleep Questionnaire (FOSQ) scores before and after PAP therapy retrospectively in a clinical SDB population using paired and two-sample t tests. Age and socioeconomic status (SES) effect modification on pre-PAP QoL measures were investigated utilizing the interaction terms.

Results

A total of 2,027 patients with SDB initiated PAP therapy between January 1, 2010 and December 31, 2014. The mean age of the cohort was 56.2 years (standard deviation = 13.2), with 45.8% female and 76.9% Caucasians. EQ-5D change after exclusion of those with normal QoL was 0.042 (0.152) in all patients, 0.051 (0.150) in patients who were PAP adherent by self-report, and 0.050 (0.132) in patients who were objectively PAP adherent (n = 704 of 1,011 with available objective adherence data, 69.6%). Change in FOSQ after excluding those with normal FOSQ was 1.9 (2.9) in all patients, 2.2 (2.9) in patients who were PAP adherent by self-report, and 2.3 (2.9) in patients who were objectively PAP adherent. Those with (1) worse QoL at baseline and younger age and (2) worse QoL at baseline and residing in lower SES strata had worse outcomes after PAP therapy (P < .05).

Conclusions

We found consistent improvement in global and sleep-specific QoL measures after PAP therapy, hence providing evidence of PAP benefit in the clinical population and rationale for targeted efforts to optimize QoL in younger and lower SES subgroups.

Project description:RationaleSleep-disordered breathing (SDB) in children is associated with cognitive challenges. However, potential associations between SDB severity and neurocognitive function, as well as the presence of an SDB cutoff, have not been fully explored.ObjectivesTo determine whether SDB-associated adverse changes in neurocognitive functioning are severity dependent.MethodsA total of 1,010 snoring and nonsnoring children ages 5-7 years were prospectively recruited from public schools and underwent polysomnography and neurocognitive assessments of intellectual, attention, memory, language, and executive function development. The children were subdivided into four severity groups on the basis of apnea-hypopnea index (AHI), followed by comparisons of cognitive function, with a particular focus on standardized subtests of intellectual, language, attention, memory, and executive function.Measurement and main resultsDifferential Ability Scales Verbal (P < 0.001) and Nonverbal (P = 0.002) performance, as well as global conceptual ability (IQ) (P < 0.001) scores, differed significantly across the groups, with individuals with higher AHI showing worse performance. Additionally, specific NEPSY (a Developmental Neuropsychological Assessment) subscores focused on attention and executive skills differed across the groups, indicating differences in levels of engagement and problem solving. Children with higher AHI (>5 per hour of total sleep time) were significantly more impaired than all three lower AHI groups, indicating a dose-response impact of SDB.ConclusionsThis large community-based sample of children highlights the significant deleterious impact of SDB, particularly in children with moderate to severe obstructive sleep apnea, and also that even snoring alone affects neurocognitive function. By affecting developing capabilities, as illustrated by cognitive measures in a severity-graded manner, SDB could adversely impact children's capacity to attain academic and adaptive goals, ultimately hampering their ability to reach independence. Our findings support the need for increased awareness of SDB, with particular emphasis on children with more severe obstructive sleep apnea.

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.
