OBJECTIVE: To report baseline characteristics of junior-level faculty participants in the Summer Institute Programs to Increase Diversity (SIPID) and the Programs to Increase Diversity among individuals engaged in Health-Related Research (PRIDE), which aim to facilitate participants' career development as independent investigators in heart, lung, blood, and sleep research. DESIGN AND SETTING: Junior faculty from groups underrepresented in the biomedical-research workforce attended two, 2-3 week, annual summer research-education programs at one of six sites. Programs provided didactic and/or laboratory courses, workshops to develop research, writing and career-development skills, as well as a mentoring component, with regular contact maintained via phone, email and webinar conferences. Between summer institutes, trainees participated in a short mid-year meeting and an annual scientific meeting. Participants were surveyed during and after SIPID/PRIDE to evaluate program components. PARTICIPANTS: Junior faculty from underrepresented populations across the United States and Puerto Rico participated in one of three SIPID (2007-2010) or six PRIDE programs (2011-2014). RESULTS: Of 204 SIPID/PRIDE participants, 68% were female; 67% African American and 27% Hispanic/Latino; at enrollment, 75% were assistant professors and 15% instructors, with most (96%) on non-tenure track. Fifty-eight percent had research doctorates (PhD, ScD) and 42% had medical (MD, DO) degrees. Mentees' feedback about the program indicated skills development (eg, manuscript and grant writing), access to networking, and mentoring were the most beneficial elements of SIPID and PRIDE programs. Grant awards shifted from primarily mentored research mechanisms to primarily independent investigator awards after training. CONCLUSIONS: Mentees reported their career development benefited from SIPID and PRIDE participation.

Introduction: Fifteen million adults in the U.S. work shift schedules (characterized by work outside the conventional daytime), including on-call, night, and rotating shifts. Shift work is associated with health risks, including Type II Diabetes, hypertension, cardiovascular disease, and obstructive sleep apnea (OSA). Recent media coverage of drowsy driving incidents in transportation workers (bus and train operators) suggest current efforts to promote awareness and treatment for OSA are ineffective. In the current study, we examined sleep among transportation workers and identified avenues for programs to improve sleep health in this high-risk population. Methods: We analyzed data from surveys of employees who work in transportation (truck, snow plough, construction operators) on shift work schedules in the rural Northeast (N = 239). Participants filled out pen-and-paper surveys assessing sleep characteristics including total sleep time, sleep quality, sleep habits (using the Sleep Hygiene Index) daytime sleepiness using the Epworth Sleepiness Scale; sleep apnea risk (according to the Apnea Risk Evaluation System, ARES); and demographic/clinical factors. Results: Among the survey respondents, 42.7% (n=27) reported hypertension, 16.4% (n=18) reported sleep apnea, and 14.5% (n=16) reported diabetes. Overall, 40.5% (n=105) reported short sleep (<6hrs), while 52.1% reported sleep between 6 and 9hrs, and 0.8% reported long sleep (>9hrs). Among respondents, 24.7% (n=64) reported "very bad" or "fairly bad" sleep quality. Responses to sleep hygiene identified prevalent, but modifiable sleep habits; 55.6% (n=144) "think, plan, or worry in bed," and 48.6% (n=126) "use alcohol, tobacco, or caffeine within 4hrs of bedtime." In response to "frequency of snoring", 64.1% (n=166) of participants report "sometimes," "frequently," or "almost always" snoring. Finally, a majority of participants, 54.5% (n=60) were at "moderate" to "high" risk for OSA (>=4 on the ARES). Conclusion: Although sleep health is critical for vigilance and safe driving, individuals in transportation working on shift schedules have poor sleep quality, insufficient sleep, and are at risk for OSA. Future research should use tailored interventions to reduce modifiable barriers (e.g., caffeine close to bedtime) among transportation shift workers to improve sleep health and implement initiatives to improve OSA screening and treatment

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. TRIAL REGISTRATION: The study is registered at clinicaltrials.gov, reference number NCT02507089 . Registered on 21 July 2015.

Masked hypertension is associated with increased risk for cardiovascular disease. Identifying modifiable risk factors for masked hypertension could provide approaches to reduce its prevalence. Life's Simple 7 is a measure of cardiovascular health developed by the American Heart Association that includes body mass index, physical activity, diet, cigarette smoking, blood pressure (BP), cholesterol, and glucose. We examined the association between cardiovascular health and masked daytime hypertension in the Jackson Heart Study, an exclusively black cohort. Life's Simple 7 factors were assessed during a study visit and categorized as poor, intermediate, or ideal. Ambulatory BP monitoring was performed after the study visit. Using BP measured between 10:00 am and 8:00 pm on ambulatory BP monitoring, masked daytime hypertension was defined as mean clinic systolic BP/diastolic BP <140/90 mm Hg and mean daytime systolic BP/diastolic BP >/=135/85 mm Hg. Among the 758 participants with systolic BP/diastolic BP <140/90 mm Hg, 30.5% had masked daytime hypertension. The multivariable-adjusted prevalence ratios for masked daytime hypertension comparing participants with 2, 3, and >/=4 versus
