AI Article Synopsis
- Sleep plays a crucial role in regulating neuroendocrine function and metabolism, and insufficient sleep during adolescence may contribute to obesity.
- The study examined the relationship between nighttime sleep duration, overweight status, and metabolic changes in adolescents aged 12 to 17 in Valencia, Venezuela.
- Results indicated that adolescents with excess weight experienced fewer sleep hours and greater sleep deficits, and those with sleep debt had a significantly higher risk of being overweight, alongside metabolic issues like low HDL cholesterol and insulin resistance.
Article Abstract
Introduction: Sleep modulates neuroendocrine function and metabolism; therefore, changes in sleep duration may lead to developing obesity during adolescence.
Objective: To assess the possible association among nocturnal sleep duration, the presence of overweight and metabolic alterations in a group of adolescents.
Population And Methods: Cross-sectional, analytical study conducted at a school in Valencia, Venezuela, during the 2012-2013 school year. Participants were 12 to 17 year-old adolescents. A survey on nocturnal sleep duration was administered; weight, height and waist circumference were recorded; and glycemia, lipid profile and insulinemia levels were measured. Body mass index and the homeostasis model assessment of insulin resistance (HOMA-IR) index were calculated.
Results: Ninety adolescents were included. Compared to the group with normal weight, adolescents with excessive weight had, in average, fewer sleep hours Sundays through Thursdays (p < 0.05) and a higher rate of sleep deficit and sleep debt (p < 0.05). Low HDL cholesterol and insulin resistance was significantly associated with sleep debt (p < 0.05). Among adolescents with sleep debt, the risk of having excess weight was 2.70 times higher (95% CI= 1.09-6.72; p= 0.032) regardless of age, gender, sexual maturity, sleep deficit Sundays through Thursdays, and history of cardiovascular disease and diabetes in first-degree relatives.
Conclusions: Nocturnal sleep deficit and sleep debt were significantly associated with excess weight and metabolic alterations related to a high cardiometabolic risk.

Circadian rhythm disruption (CRD), stemming from sleep disorders and/or shift work, is a risk factor for reproductive dysfunction. CRD has been reported to disturb nocturnal melatonin signaling, which plays a crucial role in female reproduction as a circadian regulator and an antioxidant. The hypothalamic-pituitary-ovarian (HPO) axis regulates female reproduction, with luteinizing hormone (LH) pulse pattern playing a pivotal role in folliculogenesis and steroidogenesis.

Purpose: To identify sleep dimensions (characteristics) that co-occur in premenopausal women. The second aim was to examine associations between multiple dimensions of sleep and a set of demographic, lifestyle, and health correlates. The overarching goal was to uncover patterns of poor-sleep correlates that might inform interventions to improve sleep health of women in this age group.

Patients with overactive bladder syndrome-wet (OAB-wet) experience urgency urinary incontinence, particularly urinary frequency and nocturia. Nocturnal enuresis (NE) is less addressed among OAB-wet patients. The study evaluated the prevalence of NE, lower urinary tract symptoms (LUTS), urodynamic factors, and social factors in OAB-wet patient.
