Desynchrony between eating and sleeping patterns and poor sleep quality have been associated with obesity and metabolic abnormalities. This study examined the metabolic health correlates of night eating syndrome in adults enrolled in the QUALITY cohort study.

Night eating symptoms were assessed in 310 women (mean age = 40.3 ± 5.1 years, mean BMI = 28.8 ± 6.2 kg/m2) and 305 men (mean age = 42.5 ± 5.9 years, mean BMI = 30.3 ± 5.0 kg/m2). Anthropometric measures, fasting blood samples and blood pressure were used to diagnose metabolic syndrome (MetS) and type 2 diabetes (T2D) diagnosis was self-report. Correlational and case/control comparisons assessed night eating symptoms in persons with and without MetS and T2D.

Night eating questionnaire (NEQ) scores were positively correlated with BMI. When controlling for BMI, NEQ scores were significantly negatively correlated with blood pressure in women and positively correlated with waist circumference and triglycerides in men. MetS diagnosis was associated with morning anorexia in both women and men and urges to eat at night in women only. T2D was associated with a depressed mood in women and with insomnia in men.

Symptoms of night eating syndrome are associated with higher BMI and poor metabolic health. Future research is needed to determine if night eating syndrome per se is a unique causal pathway in the development of obesity and metabolic disease.

    ABSTRACT: The timing of food intake may be implicated in weight gain. This study tested the hypothesis that symptoms commonly associated with night eating syndrome are related to measures of weight gain in adults. Parents participating in QUALITY completed the Night Eating Questionnaire (NEQ) at baseline (2005-2008) and at follow-up (2008-2010). Height and weight were measured and self-report questionnaire data were available for 388 parents (59% female, mean (SD) age: 41.8±5.7, mean (SD) body mass index (BMI): 29.6±5.7). Linear regression models were used to test the associations between baseline night eating symptoms (NEQ scores, night eating behaviours) and percent change in each of BMI and waist circumference (WC). A high NEQ score predicted a small increase in percent change in BMI in non-obese parents but a decrease among those who were severely obese. Nocturnal ingestions of food predicted an increase in percent change in BMI; however, the effect size was small. Morning anorexia predicted an increase in percent change in WC. Certain night eating symptoms may predict measures of weight gain in adults but the effects seem small and the findings need to be confirmed in more symptomatic samples.International Journal of Obesity accepted article preview online, 23 March 2015. doi:10.1038/ijo.2015.36.

    ABSTRACT: Objective: Insufficient sleep is a risk factor for pediatric obesity. Latino children are among those groups in which both short sleep duration and obesity are prevalent. Therefore, this study sought to explore Latino parents' views about ideal sleep duration and sleep-related practices for their preschool-age children in an urban setting. Methods: Between October 2013 and January 2014, Latino parents of 2- to 5-year-old children were interviewed at 3 pediatric clinics (San Francisco, Calif). Using a semistructured interview guide, parents were asked to describe bedtime routines and sleep practices of their preschool-age children, including behavioral, parental, social, and contextual factors that may affect children's sleep. Interviews were conducted in Spanish and English. Parents also completed a brief survey on demographic information. Interviews were analyzed on the basis of a priori and emergent themes. Results: Latino parents (n = 18) were mostly female, with a mean age of 31 years; most were foreign born; and more than half had a monthly household income of $2000 or less. The following themes emerged: parents' ideas about optimal sleep duration for their preschool-age child, consistent bedtime routines, room sharing and bed sharing, parent work and child school schedules that affect children's sleep, and crowded housing and neighborhood noise that disrupt children's sleep. Conclusions: These findings increase our understanding of the factors related to achieving optimal sleep duration among Latino children living in urban and often crowded housing. Findings could be used to inform future research on how to increase parental knowledge of healthy sleep practices and adequate sleep among Latino parents of young children.
