This data was generated from a two-arm randomized controlled trial. The study evaluated the effectiveness of a culturally and linguistically tailored telephone-delivered intervention to promote adherence to physician-recommended sleep apnea assessment and treatment among black patients with metabolic syndrome. Outcomes of interest (diabetes mellitus, hypertension, and dyslipidemia) were assessed at baseline, 6, and 12 months post-randomization. Participants in the intervention arm received 10 phone calls to address the challenges and barriers to recommended care for sleep apnea. A total of 344 participants were recruited.

Sociodemographic variables, including age, type of health insurance, marital status, education, place of birth, years in current residence and locality, number of children and adults living in the household, self-described ethnicity, and annual household income were collected. The Apnea Risk Evaluation System (ARES™) questionnaire was used to collect information on sleep patterns, daytime functioning, knowledge of sleep apnea, and diseases associated with sleep apnea. Other questionnaires collected information on knowledge of and belief in sleep apnea and included a 32-item instrument used to assess a person's readiness to change their behaviors. Data on patient medical history (including sleep disorders, obesity, diabetes mellitus, hypertension, dyslipidemia) and health behaviors were also collected.
