However, the relationship between habitual sleep duration and blood pressure values in Japanese population has not been fully established. We performed a cross-sectional study of 1,670 Japanese male subjects to clarify the relationship between habitual sleep duration and blood pressure values. The study subjects were divided into four groups (< 6, 6-, 7-, and a parts per thousand yen8 h) according to their nightly habitual sleep duration. The rate of subjects with < 6, 6-, 7-, and a parts per thousand yen8 h sleep duration was 12.0, 37.6, 38.2, and 12.2 %, respectively. Compared with the group with 7-h sleep duration (referent), the < 6 and a parts per thousand yen8 h groups had significantly greater systolic and diastolic blood pressure values. The rate of hypertensive subjects, defined as systolic blood pressure a parts per thousand yen140 mmHg and/or diastolic blood pressure a parts per thousand yen90 mmHg, with sleep duration of < 6, 6-, 7-, and a parts per thousand yen8 h was 13.4, 5.7, 7.5, and 13.8 %, respectively. Compared with the group with 7-h sleep duration (referent), the multivariate odds ratios (95 % confidence interval) of the groups with < 6 and a parts per thousand yen8 h for hypertension was 2.43 (1.40-4.20, P < 0.01) and 2.28 (1.31-3.95, P < 0.01), respectively, adjusted for conventional cardiovascular risk factors. The present study demonstrates that both long and short habitual sleep duration were significantly associated with high blood pressure values and hypertension occurrence in Japanese male subjects.Springer - Japanese Society for HygieneJournal Articleapplication/pdfhttp://hdl.handle.net/2115/53243https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/53243/1/18_3_215.pdf1347-4715Environmental Health and Preventive Medicine2013182152202013-09-27enginfo:doi/10.1007/s12199-012-0309-3The original publication is available at http://www. springerlink.com.author
