Associations of Weekday and Weekend Sleep with Children's Reported Eating in the Absence of Hunger.

ABSTRACT: Insufficient average sleep duration has been inconsistently associated with poor diet and obesity risks in youth. Inconsistencies in findings across studies may be due to a general failure to examine associations in weekday versus weekend sleep. We hypothesized that greater variations in weekday and weekend sleep duration would be associated with more disinhibited eating behaviors, which, in turn, might be involved in the relationship between sleep and weight. We, therefore, examined, among healthy, non-treatment seeking youth, the associations of average weekly, weekend, and weekday sleep duration with eating in the absence of hunger (EAH), a disinhibited eating behavior associated with disordered eating and obesity. Sleep was assessed via actigraphy for 14 days. Participants completed a self-report measure of EAH. Adiposity was measured by dual-energy X-ray absorptiometry. Linear regressions were used to test the associations of sleep duration with EAH and the associations of sleep duration and EAH, with fat mass. Among 123 participants (8-17 years, 52.0% female, and 30.9% with overweight), there was no significant association between average weekly sleep and EAH. Further, there was no significant association among average weekly sleep duration or EAH and fat mass. However, average weekday sleep was negatively associated, and average weekend sleep was positively associated, with EAH (ps < 0.02). Weekend "catch-up" sleep (the difference between weekend and weekday sleep) was positively associated with EAH (p < 0.01). Findings indicate that shorter weekday sleep and greater weekend "catch-up" sleep are associated with EAH, which may place youth at risk for the development of excess weight gain over time.

Project description:ObjectiveExposure to impaired gestational glucose tolerance has been shown to have sex-specific associations with offspring obesity risk, perhaps by affecting the development of appetite regulation. We examined the extent to which prenatal exposure to impaired glucose tolerance was associated with eating in the absence of hunger (EAH) in early adolescent offspring, and in turn, whether EAH was cross-sectionally associated with body composition.MethodsWe included data from 1097 adolescents participating in Project Viva, a pre-birth longitudinal cohort. We obtained the results of two-stage prenatal glycemic screening (50 g glucose challenge test, followed if abnormal by 100 g oral glucose tolerance test) at 26-28 weeks of gestation, and categorized mothers as having normal glucose tolerance, isolated hyperglycemia (IH, n = 92, 8.4%), impaired glucose tolerance (IGT, n = 36, 3.3%), or gestational diabetes mellitus (GDM, n = 52, 4.7%). At a median age of 13 years, offspring reported on two modified items of the Eating in the Absence of Hunger in Children and Adolescents questionnaire, we measured height and weight, and performed dual X-ray absorptiometry scans to assess fat and fat-free mass. We used multivariable linear regression analyses adjusted for sociodemographic and prenatal covariates, including maternal pre-pregnancy BMI.ResultsOn a ten-point scale, the mean (SD) EAH score was 4.4 points (SD = 1.5) in boys and 4.4 (SD = 1.4) in girls. In girls, prenatal exposure to both IH and IGT was associated with more EAH compared with normal glucose tolerance (e.g., for IH: 0.56 points, 95% CI: 0.17, 0.96), whereas in boys, prenatal exposure to IGT was associated with less EAH (-0.81 points, 95% CI: -1.41, -0.21). We did not observe an association between exposure to GDM and EAH, nor did we observe associations between EAH and body composition in early adolescence.ConclusionsThese findings suggest sex-specific associations of exposure to impaired gestational glucose tolerance with offspring EAH in early adolescence.

Project description:BackgroundScant research has examined whether laboratory assessments of eating in the absence of hunger (EAH) relates to long-term diet quality.ObjectiveThis study investigates the association of EAH with diet quality during pregnancy.DesignPregnancy diet quality was assessed using 24-hour diet recalls collected in each pregnancy trimester. EAH was assessed in a counterbalanced, crossover laboratory feeding substudy in which participants completed two free access eating occasions following a standardized meal during their second pregnancy trimester.Participants/settingData were collected from March 2015 to December 2016 from a subsample of participants (n = 46) enrolled at ≤12 weeks' gestation in an observational, prospective cohort study (the Pregnancy Eating Attributes Study) in North Carolina.InterventionParticipants were presented with highly processed (HP) and minimally processed (MP) foods in two separate assessments.Main outcome measuresScores for total Healthy Eating Index-2015 (HEI-2015) and adherence to adequacy and moderation components were calculated from the diet recalls. Higher scores reflect better diet quality.Statistical analyses performedLinear regressions estimated associations of pregnancy diet quality with EAH (energy, EAH-kcal; and percent offered, EAH-%) in each condition for all foods, and separately for sweet and savory foods.ResultsLower pregnancy diet quality (all indicators) was associated with greater EAH (EAH-kcal and EAH-%) of all foods and sweet foods in the HP condition. Each 100-kcal increase in EAH of HP foods was associated with a 2- to 3-point decrease (standard error = 0.7 to 0.8) in HEI-2015 (P < 0.01); each 10% increase in EAH of HP foods was associated with a 5- to 7-point decrease (standard error = 2.0) in HEI-2015 (P < 0.01). Greater EAH (energy and percent offered) of savory food intake in the HP condition was associated with a lower HEI-2015 adequacy component score, but was not associated with the HEI-2015 or HEI-2015 moderation component scores. EAH in the MP condition was not associated with pregnancy diet quality.ConclusionsGreater EAH of HP, especially sweet, foods was related to worse pregnancy diet quality. Consuming HP sweets after meal termination may reflect a tendency for eating beyond satiation and may be a useful intervention target for improving maternal diet quality.
