Daytime Nappers at Risk for Hypertension
Future studies are needed to assess potential benefits of hypertension screening for daytime nappers.
HealthDay News — Daytime napping appears to be associated with increased risk of hypertension, according to a review and meta-analysis published online in the Journal of Evidence-Based Medicine.
Wisit Cheungpasitporn, MD, from the Mayo Clinic in Rochester, Minn., and colleagues conducted a systematic literature review to examine the correlation between napping and hypertension. Data were included from 9 observational studies with 112,267 individuals.
The researchers found that in nappers the pooled risk ratio of hypertension was 1.13 (95% confidence interval, 0.98 to 1.30). In studies assessing the risk of hypertension in daytime nappers only, the pooled risk ratio for hypertension was 1.19 (95% confidence interval, 1.06 to 1.35). Limited data examined the correlation between nighttime napping and hypertension in individuals who worked night shifts, with one observational study reporting a reduced risk of hypertension (odds ratio, 0.79; 95% confidence interval, 0.63 to 1.00).
"Our meta-analysis demonstrates a significant association between daytime napping and hypertension," the authors write. "Future study is needed to assess the potential benefits of hypertension screening for daytime nappers."
