Abstract
Rationale: Sleep disorders are associated with hypertension and diabetes, which are primary risk factors for cardiovascular diseases and mortality. It is important to understand these associations in Hispanic/Latino individuals, in whom cardiovascular death is the leading cause of mortality.Objectives: To investigate the prospective associations of sleep-disordered breathing (SDB) and insomnia with incident hypertension and diabetes among U.S. Hispanic/Latino people over 6 years of follow-up and to assess potential sex differences in these associations.Methods: Data from 11,623 Hispanic/Latino participants in the Hispanic Community Health Study/Study of Latinos (visit 1, 2008-2011; visit 2, 2014-2017) were analyzed using survey logistic regression models, adjusting for potential confounders.Measurements and Main Results: SDB (apnea-hypopnea index of 5 or more) and insomnia (Women's Health Initiative Insomnia Rating Scale of 9 or more) were measured at baseline. Incident hypertension (stage 2 or greater) and diabetes were defined according to national guidelines. In the target population, 52.6% were women, with a mean age of 41.1 ± 14.9 years at baseline. SDB was associated with 1.54 higher adjusted odds of incident hypertension (95% confidence interval [CI], 1.18-2.00) and 1.33 higher odds of incident diabetes (95% CI, 1.05-1.67) compared with no SDB. Insomnia was associated with incident hypertension (odds ratio, 1.37; 95% CI, 1.11-1.69) but not with diabetes. The association between insomnia and incident hypertension was stronger among men than among women.Conclusions: SDB was associated with incident hypertension and diabetes. Insomnia was associated with incident hypertension. These findings support the importance of sleep disorders as modifiable targets for disease prevention and reduction.
