Abstract

STUDY OBJECTIVES: To investigate the association between short sleep duration and elevated body mass index (BMI) and obesity in a large sample of Japanese adults over a short period. DESIGN: Prospective design with baseline in 2006 and 1-year follow-up. SETTING: Workplaces of an electric power company in Japan. PARTICIPANTS: 35,247 company employees (31,477 men, 3,770 women) distributed throughout Japan. MEASUREMENTS AND RESULTS: Measured weight and height and self-reported sleep duration were obtained at annual health checkup in 2006 and 2007. Weight change was defined as the difference in body mass index (BMI) between the baseline and 1 year later. Relative to the reference category (sleep duration 7-8 h), short sleep duration (< 5 and 5-6 h) and long sleep duration > or = 9 h were associated with an increased risk of weight gain among men after adjustment for covariates. Of the non-obese (BMI < 25) men at baseline, 5.8% became obese (BMI > or = 25) 1 year later. Higher incidence of obesity was observed among the groups with shorter sleep duration. Adjusted odds ratios for the development of obesity were 1.91 (95% CI 1.36, 2.67) and 1.50 (95% CI 1.24, 1.80) in men who slept < 5 and 5-6 h, respectively. No significant association between sleep duration and weight gain or obesity was found for women. CONCLUSIONS: Short sleep duration was associated with weight gain and the development of obesity over 1 year in men, but not in women.

  • In a study of male Japanese workers, habitual sleep duration of less than 6 hours was associated with increased likelihood of developing obesity over 1 year.

    “In a study of male Japanese workers,46 habitual sleep duration of <6 hours was associated with increased likelihood of developing obesity over the course of 1 year.”
  • Some adult prospective studies report U- or L-shaped associations, so the link between longer sleep and BMI is conflicting in adults and absent in children.

    “U- or L-shaped associations were reported in some adult prospective studies (reviewed in [80]; additional studies: [97, 202]); hence, the relationship between longer sleep and BMI is conflicting in adults and inexistent in children.”

  • Several longitudinal studies demonstrate that short sleep duration is associated with increased weight gain over time.

  • Short sleep duration is associated with obesity-related outcomes, including incident weight gain, incident obesity, current body mass index, and current adiposity.

    “short sleep duration has been associated with obesity-related outcomes, diabetes-related outcomes, and cardiovascular-related outcomes. Regarding obesity-related outcomes, short sleep duration has been associated with incident weight gain (Kobayashi et al., 2012; Nagai et al., 2013), incident obesity (Watanabe et al., 2010), current body mass index (Patel, 2009), and current adiposity(Chaput et al”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
