Tailored approach to sleep health education (TASHE): study protocol for a web-based randomized controlled trial

Background: Obstructive sleep apnea (OSA) is a sleep disorder that disproportionately affects African Americans (hereafter referred to as blacks). Moreover, blacks may underutilize sleep services including overnight polysomnography. Thus, OSA among blacks may go undiagnosed and untreated, which has significant health consequences, including hypertension, diabetes, cognitive impairment, and daytime sleepiness. Design and Methods: This two-arm randomized controlled trial will assign 200 participants to a culturally and linguistically tailored web-based sleep educational platform. The website will be developed to ensure that the content is user friendly and that it is readable and acceptable by the target community. Participants will receive login information to a password-protected website and will have access to the website for 2 months. Study assessments will be collected at baseline, 2 months (post-enrollment) and at 6 months (follow-up). We will use qualitative and quantitative methods to develop tailored materials and to ascertain whether tailored materials will increase OSA knowledge and OSA health literacy by comparing blacks exposed to tailored materials versus those exposed to standard sleep health literature. We hypothesize that exposure to tailored OSA information will improve OSA health literacy. Discussion: Few studies have investigated the racial/ethnic disparities in relation to OSA screening and treatment comparing blacks and whites. Moreover, we know of no interventions designed to increase OSA knowledge and health literacy among blacks. Use of the Internet to disseminate health information is growing in this population. Thus, the Internet may be an effective means to increase OSA health literacy, thereby potentially increasing utilization of sleep-related services in this population

Developing a Tailored Website for Promoting Awareness about Obstructive Sleep Apnea (OSA) Among Blacks in Community-Based Settings

Blacks are at greater risk for lower sleep quality and higher risk for obstructive sleep apnea (OSA) than other racial groups. In this study, we summarize the development of a tailored website including visuals, key messages, and video narratives, to promote awareness about sleep apnea among community-dwelling blacks. We utilized mixed methods, including in-depth interviews, usability-testing procedures, and brief surveys (n = 9, 55% female, 100% black, average age 38.5 years). Themes from the qualitative analysis illuminated varied knowledge regarding OSA symptoms and prevalent self-reported experience with sleep disturbance and OSA symptoms (e.g., snoring). On a scale from 1 (not at all) to 5 (very high), participants provided favorable ratings of website usefulness (mean = 4.9), user friendliness (mean = 4.9) and attractiveness (mean = 4.3). Our findings suggest although tailored health communication has potential for serving as a tool for advancing health equity, usability-testing of health materials is critical to ensure that culturally and linguistically tailored messages are acceptable and actionable in the intended population

Sleep, Melatonin, and the Menopausal Transition: What Are the Links?

The pineal hormone Melatonin plays an important role in the regulation of the circadian sleep wake cycle, mood, and perhaps immune functions, caminogensis and reproduction. The human circadian rhythm of melatonin release from the pineal gland is tightly synchronized with the habitual hours of sleep. Peri-and postmenopausal women often complain of difficulties initiating and/or maintaining sleep, with frequent nocturnal and early morning awakenings. In this review we discuss the pathophysiology of melatonin function as it relates to sleep disorders in menopausal women, highlighting the potential use of exogenous melatonin during the menopausal transition and beyond

Insomnia symptoms in a multiethnic sample of American women.

Tailored approaches to stroke health education (TASHE): study protocol for a randomized controlled trial

Background: Stroke is a leading cause of adult disability and mortality. Intravenous thrombolysis can minimize disability when patients present to the emergency department for treatment within the 3 − 4½ h of symptom onset. Blacks and Hispanics are more likely to die and suffer disability from stroke than whites, due in part to delayed hospital arrival and ineligibility for intravenous thrombolysis for acute stroke. Low stroke literacy (poor knowledge of stroke symptoms and when to call 911) among Blacks and Hispanics compared to whites may contribute to disparities in acute stroke treatment and outcomes. Improving stroke literacy may be a critical step along the pathway to reducing stroke disparities. The aim of the current study is to test a novel intervention to increase stroke literacy in minority populations in New York City. Design and Methods: In a two-arm cluster randomized trial, we will evaluate the effectiveness of two culturally tailored stroke education films – one in English and one in Spanish – on changing behavioral intent to call 911 for suspected stroke, compared to usual care. These films will target knowledge of stroke symptoms, the range of severity of symptoms and the therapeutic benefit of calling 911, as well as address barriers to timely presentation to the hospital. Given the success of previous church-based programs targeting behavior change in minority populations, this trial will be conducted with 250 congregants across 14 churches (125 intervention; 125 control). Our proposed outcomes are (1) recognition of stroke symptoms and (2) behavioral intent to call 911 for suspected stroke, measured using the Stroke Action Test at the 6-month and 1-year follow-up. Discussion: This is the first randomized trial of a church-placed narrative intervention to improve stroke outcomes in urban Black and Hispanic populations. A film intervention has the potential to make a significant public health impact, as film is a highly scalable and disseminable medium. Since there is at least one church in almost every neighborhood in the USA, churches have the ability and reach to play an important role in the dissemination and translation of stroke prevention programs in minority communities

791 Association of Obstructive Sleep Apnea Severity and Novel Plasma Biomarkers of Alzheimer’s Disease Pathology

Abstract Introduction Recent evidence suggests novel plasma Alzheimer’s Disease (AD) pathology biomarkers have high potential for AD risk prediction. We determined whether obstructive sleep apnea (OSA) severity is associated with plasma levels of Aβ40, Aβ42, Aβ42/Aβ40, Tau, tau/Aβ42 and NfL and whether this relationship is dependent of amyloid burden. Methods Cross-sectional analysis of baseline data from 120 community-dwelling, cognitively normal older-adults, selected from ongoing NYU prospective longitudinal studies on memory, sleep and aging. Of the 120 participants, 70 had baseline CSF-Aβ42 (measured using ELISA). OSA-severity was defined using AHI4% criteria. Levels of plasma Aβ40, Aβ42, Tau and NfL were determined using single molecule array technology ultra-sensitive assays. Associations of OSA-severity and plasma AD-biomarker levels (n=120) were assessed using Pearson correlation analysis. The association of OSA-severity and AD plasma biomarkers dependent on CSF-Aβ42 levels (n=70) was assessed using generalized linear models. Analyses were adjusted for age, sex, BMI, race, education and APOE4. Results Of the 120 participants, 80 (67%) were women. Mean (SD) age was 69.1 (7.2) years. Mean (SD) AHI was 14.3/hr. (16.3) {48 (40%) had AHI 30}. Independent of amyloid-burden, OSA-severity was associated with higher levels of plasma Aβ40 (r=.21, p-value=.02), plasma Aβ42 (r=.26, p-value=.01), plasma Aβ42/Aβ40 (r=.20, p-value=.05), but not plasma Tau, plasma tau/Aβ42 or plasma NfL. The association of OSA-severity and plasma levels of Tau, Tau/Aβ42 or NfL dependent on CSF-Aβ42 levels revealed significant interactions between CSF-Aβ42 levels and AHI (p-value <.05 for all), with β-estimates suggesting that with combined increases in AHI and decreases in CSF-Aβ42 levels, there were corresponding increases in plasma levels of Tau, plasma Tau/Aβ42 or plasma NfL. The analysis was not powered for generating dichotomized strata specific (i.e. OSA+/Aβ+, OSA+/Aβ-, OSA-/Aβ+ and OSA-/Aβ-) estimates. Conclusion In this sample of cognitively-normal older- adults, OSA-severity was associated with levels of plasma Aβ40, Aβ42, Aβ42/Aβ40 and showed a synergistic effect with CSF Aβ42 on plasma levels of tau and NfL. Larger cohorts are necessary to delineate mechanisms and examine for OSA/Aβ strata-specific estimates.
