| Summary: | AbstractInsufficient sleep may lead to adverse cardio-metabolic effectsby influencing body weight, blood pressure, and glucose tolerance.We aimed to assess the relation between sleep durationand indices of obesity including body mass index (BMI) andwaist circumference in a sample population in central Iran. Weselected a sub-sample of 1770 individuals from Isfahan HealthyHeart Program. The data regarding the sleep duration was collectedby using a validated questionnaire. The relation of sleepduration with BMI and waist circumference was examined byusing categorical logistic regression with adjustment for sex,BMI, and daily calorie intake. Sleep duration time less than 5hours/day compared with 7-8 hours/day increased the odds ratiofor abdominal obesity in people aged under 60 years [OR=2.49(95%CI 1.40-4.43)]. In individuals aged under 60 years, thisrelation was significant for both men, [OR=2.64 (95%CI 1.16-6.02]) and women [OR=2.38 (95% CI 1.05-5.39)]. In addition,in women, sleep time > 9 hours was negatively related to waistcircumference. Sleep duration time less than 5 hours per dayincreased odds ratio of overweight only in women [OR=1.75(95% CI 1.07-2.85)]. Sleep duration time under 5 hours in peopleaged less than 60 years was positively associated with waistcircumference. In women, sleep duration time over 9 hours wasnegatively associated with waist circumference. Only in women,sleep time under 5 hours /night increased BMI. Short sleep durationwas associated with abdominal obesity and this was independentof its relation to BMI.Iran J Med Sci 2010; 35(2): 140-144. |
