Objetivo: Identificar os padrões alimentares e sua relação com o estado menopáusico.Métodos: Estudo transversal com 646 mulheres em atendimento ambulatorial no Sul do Brasil. O consumo alimentar foi avaliado por questionário de frequência e cinco padrões alimentares foram identificados através da análise de componentes principais. O estado menopáusico foi classificado em pré-menopausa, perimenopausa e pós-menopausa.Resultados: Identificaram-se cinco padrões alimentares: frutas e verduras, brasileiro (arroz, feijão e leite), lanches (bolo, xis, pizza, cuca), prudente (peixe, suco natural, pão integral e sopa de legumes) e regional (alimentos típicos na serra gaúcha como carnes vermelhas, aipim e massas). Após ajuste para características sociodemográficas, não verificou-se associação significativa entre o estado menopáusico e os padrões alimentares. Apenas idade, escolaridade e renda mostraram-se associadas com padrões alimentares.Conclusão: Foram identificados cinco padrões alimentares que descreveram o consumo alimentar da população estudada, sendo estes semelhantes ao indicado como ideal para a população brasileira. Nossos achados indicam que o padrão alimentar das mulheres no climatério possui influência significativa da idade, escolaridade e renda e que não sofre influência do estado menopáusico.

ResumoFoi realizada uma revisão sistemática com o objetivo de descrever o panorama e a evolução de estudos de custo-efetividade em saúde no Brasil. A busca de artigos sobre esse assunto foi feita nas principais bases de dados da área da saúde. A revisão identificou 83 estudos de custo-efetividade realizados em âmbito nacional. Entre os anos de 1990 a 2005 houve poucos estudos publicados sobre custo-efetividade e entre 2006 e 2014 houve um aumento expressivo do número de publicações. Quanto aos temas e objetivos dos estudos, as doenças de caráter crônico-degenerativas e as infectocontagiosas refletem a diversidade epidemiológica do Brasil. Identificou-se uma predominância dos estudos relativos à intervenção/tratamentos em saúde. Assim, a presente revisão revela um cenário compatível com a realidade epidemiológica brasileira, indicando uma necessidade no aumento de estudos e investimentos de recursos na área da prevenção em saúde.

Summary A systematic review with meta‐analysis (MA) was conducted to synthesize the effectiveness of nutrition intervention strategies for managing overweight and obesity in the adult population attending primary health care. Relevant articles were searched in the PubMed, Embase, Web of Science, Cochrane and LILACS databases from inception to January 2020. Seventy studies were identified: 45 randomized controlled trials (RCTs) and 25 uncontrolled before‐after studies (UBAs). The MA of nutritional intervention revealed a reduced average estimate of the effect on weight in RCTs (weighted mean differences [WMD] = −1.80 kg, 95% confidence interval [CI], −2.40 to −1.19), BMI (WMD = −0.80 kg/m2, 95% CI, −1.11 to −0.49), and WC (WMD = −2.28 cm, 95% CI, −3.06 to −1.49); and for UBAs showed reductions in weight (WMD = −4.17 kg; 95% CI, −5.18 to −1.70), BMI (WMD = −1.26 kg/m2; 95% CI, −1.81 to −0.72) and (WMD = −2.90 cm; 95%CI, −4.21 to −1.59). There was no association between treatment effect and follow‐up for both designs. Nutritional interventions alone yielded a higher but nonsignificant average reduction on weight when compared with combined components intervention. Interventions delivered through individual or group sessions showed a similar positive effect on weight decrease. The dietary prescription approach yielded a greater effect on weight loss than did the behavioural approaches but only in UBA studies.

workers, such as changing positions frequently during work and implementation of rest breaks and a workplace exercise program, so as to improve worker quality of life. (J Occup Health 2015; 57: 448-456)

Workplace social cohesion may play an important role in the promotion of mental health and healthy behaviors among women employees.

Objectives: To explore the relationship between work-related stress and obesity among female shift workers. Additionally, we also aimed to test the interaction between shift work and work-related stress in this association. Design: A cross-sectional study was conducted among Brazilian female shift workers. Work-related stress was assessed through a demand–control questionnaire (Job Stress Scale). Work-related stress was defined by presence of high psychological demands and low control at work. The obesity cases were defined as those with a body mass index of 30 kg/m2 or more. Multivariate Poisson regression with robust variance was used to obtain the prevalence ratios (PRs) and their respective 95% confidence intervals (95% CIs). Setting: A group of industries located in southern Brazil in 2017. Participants: 420 female workers aged 18–59 years. Results: The overall prevalence of obesity was 30% (95% CI: 25.6 to 34.4) and the presence of work-related stress was identified in 24% (95% CI: 19.9 to 28.1) of the sample. We found an indication of interaction between work-related stress and night shift work on obesity (P = 0.026). After adjusting for confounding factors, work-related stress was associated with a 71% greater probability of obesity (PR = 1.71; 95% CI: 1.02 to 2.87; P = 0.042) among female night shift workers. Conclusions: In this study, we revealed that exposure to work-related stress and night shift work were associated with obesity among female shift workers. Furthermore, the prevalence of obesity was high among female shift workers.

There is not sufficient evidence confirming the association between eating frequency and body weight or body composition when misreporting bias is taken into account. However, in men, a potential protective effect of high eating frequency was observed on BMI and visceral obesity.
