Default Association between weight gain, obesity, and sleep duration

Association between weight gain, obesity, and sleep duration
Previous research suggests that sleep duration is associated with obesity and weight gain. However, the majority of these studies are of cross-sectional design, with only a few cohort studies. In order to validate previous findings in a more real-world context, we evaluated the association between sleep duration, obesity, and weight gain in a large, 3-year cohort study.
A retrospective cohort study was conducted involving 21,469 apparently healthy individuals aged 20 years or older who underwent annual health check-ups at the Center for Preventive Medicine, St. Luke's International Hospital, between 2005 and 2008. The participants were divided into four groups according to their self-reported average nightly sleep duration (≤5, 6, 7, and ≥8 h). We identified individuals with obesity (body mass index ≥25 kg/m(2)) and weight gain. Multivariate linear regression analysis and logistic regression analysis were used to explore the association between these variables and sleep duration, adjusting for age, gender, alcohol consumption, current smoking, past medical history, and level of physical activity.
Compared with those who slept 7 h, the individuals who slept ≤5 h night were more likely to experience weight gain (β coefficient = 0.03; 95% CI = 0.03-1.1) and to become obese (OR = 1.5; 95% CI = 1.1-2.0). No significant difference was seen between subjects who slept more than 8 h and those sleeping 7 h (OR = 1.3; 95% CI = 0.9-1.8).
Short sleep (≤5 h) is significantly associated with weight gain and obesity in both male and female adults.

It's worth considering if this is the case for adults it probably also applies to children and I don't think my grandchildren spend as long in bed asleep as my kids did and certainly less than when I was a boy. I'm sure nightlights, TV's PC's electronic games, general noise levels and light pollution in towns and houses, all make the quality/duration of sleep less than previous generations enjoyed.

Can't tell that by me. My sleep is very disturbed by my sinus condition. Has been for many years. I'm underweight.

It's like those political surveys. I sometimes wonder how they come up with those stats, because nobody ever asks me.

I've heard that stress can cause weight gain --- and loss. I think they should look at a broader picture.
