“…Both night-eating syndrome and shift work may be associated with obesity and metabolic syndromes (9,32,33), which could result in susceptibility to various diseases such as cardiovascular diseases and cancer. Psychiatric symptoms are associated with nighteating syndrome, shift work, and jet lag conditions (9,10,34).…”

Temporally restricted feeding (RF) can phase reset the circadian clocks in numerous tissues in mammals, contributing to altered timing of behavioral and physiological rhythms. However, little is known regarding the underlying molecular mechanism. Here we demonstrate a role for the gamma isotype of protein kinase C (PKCγ) in food-mediated entrainment of behavior and the molecular clock. We found that daytime RF reduced late-night activity in wild-type mice but not mice homozygous for a null mutation of PKCγ (PKCγ). Molecular analysis revealed that PKCγ exhibited RF-induced changes in activation patterns in the cerebral cortex and that RF failed to substantially phase shift the oscillation of clock gene transcripts in the absence of PKCγ. PKCγ exerts effects on the clock, at least in part, by stabilizing the core clock component brain and muscle aryl hydrocarbon receptor nuclear translocator like 1 (BMAL1) and reducing its ubiquitylation in a deubiquitination-dependent manner. Taken together, these results suggest that PKCγ plays a role in food entrainment by regulating BMAL1 stability.

“…Sugar, especially in large quantity and when consumed frequently, is also known to contribute to the development of caries (5)(6)(7) . Further, shorter sleep duration and nocturnal eating have been associated with overweight and obesity (8)(9)(10) as well as with dental disease (11,12) .…”

Objective: The objective of the present study was to investigate the association between salivary counts of mutans streptococci (MS) and children's weight status, while considering associated covariates. MS ferments carbohydrates from the diet and contributes to caries by lowering the pH in dental plaque. In adults, high counts of MS in saliva have been associated with overweight, but this has not been shown in children. Design: Cross-sectional study investigating salivary counts of MS, BMI Z-score, waist circumference, meal frequency, sugar propensity and sleep duration, in children. Setting: West Sweden. Subjects: Children (n 271) aged 4-11 years. Results: Medium-high counts of MS were positively associated with higher BMI Z-score (OR = 1·6; 95 % CI 1·1, 2·3). Positive associations were also found between medium-high counts of MS and more frequent meals per day (OR = 1·5; 95 % CI 1·1, 2·2), greater percentage of sugar-rich foods consumed (OR = 1·1; 95 % CI 1·0, 1·3) and female sex (OR = 2·4; 95 % CI 1·1, 5·4). A negative association was found between medium-high counts of MS and longer sleep duration (OR = 0·5; 95 % CI 0·3, 1·0). Conclusions: BMI Z-score was associated with counts of MS. Promoting adequate sleep duration and limiting the intake frequency of sugar-rich foods and beverages could provide multiple benefits in public health interventions aimed at reducing dental caries and childhood overweight.

“…Os desequilíbrios circadianos reforçam a ligação entre a SCN com a obesidade, assim, teoricamente a SCN poderia levar ao ganho de peso sendo resultado do excesso de calorias consumidas durante a noite. Com efeito, estudos têm mostrado que o comer noturno leva ao ganho de peso e que o início da obesidade ocorre mais cedo na vida daqueles com a síndrome (GALLANT et al, 2012).…”

Incidência Da Síndrome Do Comer Noturno E Compulsão Alimentar Em Estudantes De Nutrição

RESUMO:O presente trabalho objetiva caracterizar a incidência da síndrome do comer noturno e a compulsão alimentar em estudantes do curso de nutrição. Trata-se de um estudo transversal de caráter analítico realizado em uma instituição de nível superior em Petrolina -PE. Foram aplicados três questionários: questionário de hábitos do comer noturno, a escala de ingestão compulsiva e o The Three factor eating questionnaire. Avaliaram-se 81 estudantes de ambos os sexos, com predominância do sexo feminino. Não houve associação significativa entre a síndrome do comer noturno ou a compulsão alimentar com as variáveis sexo e escolaridade. Em relação às variáveis comportamentais, a alimentação emocional foi o fator melhor relacionado ao descontrole alimentar e a restrição cognitiva tem pouca contribuição para o agravamento da alimentação descontrolada. O investimento no estudo dos transtornos alimentares é importante para a criação de uma intervenção adequada, com o intuito de reduzir incidência tanto da SCN como da compulsão alimentar. PALAVRAS-CHAVE:Transtorno da compulsão alimentar; Estudantes; Transtornos da Alimentação e da Ingestão de Alimentos. OCCURRENCE OF NIGHT-EATING SYNDROME AND FEED COMPULSIVE DISORDER IN NUTRITION STUDENTSABSTRACT: Occurrence of night-eating syndrome and feed compulsive disorder in students of the Nutrition Course is analyzed in current transversal and analytic study at a higher education institute in Petrolina PE Brazil. Three questionnaires were applied, namely, a questionnaires on habits in night-eating, compulsive ingestion scale and the Threefactor eating questionnaire. Eighty-one students, males and females, mostly the latter, were evaluated. There was no significant association between night-eating syndrome or feed compulsive disorder for the variables gender and schooling. In the case of behavioral variables, emotional feeding was the factor which was most related to lack of control in feeding, whilst cognitive restriction scantily contributed towards the worsening of uncontrolled feeding. Studies on feeding disorders are important for an adequate intervention to reduce occurrence in NES and feeding compulsive disorder.
