Objective The aim of the present study was to assess the anthropometric measures, food intake and food cravings during the menstrual cycle of undergraduate students of the faculty of nutrition. Methods A cross-sectional study was performed with 27 students from a public university in the state of Mato Grosso do Sul, Brazil, who had their food intake evaluated through a 24-hour food recall, their nutritional status evaluated based on anthropometric measures, and food cravings evaluated using the Food Desire Questionnaire. Data were collected during an evaluation in the follicular phase (between the 5^th and the 9^th day of the menstrual cycle) and another in the luteal phase (LP) (between the 20^th and the 25^th day of the menstrual cycle). For food intake variables, the analysis of variance (ANOVA) test was used, followed by the Tukey test. The Mann-Whitney test was used for the analysis of food cravings, considering a significance level of 5% (p < 0.05). Results The desire for foods rich in sugar, salt, and fat, such as chocolate, pastries, snacks and desserts were higher (p < 0.05) during the premenstrual period, although it did not reflect neither a higher energy intake nor an alteration in the distribution of macronutrients. A higher intake of carbohydrates, proteins, fibers, and calcium was observed during the LP; however, without statistical difference between the groups. There were no differences either in the intake of any food group or in the anthropometric measurements (p > 0.05). Conclusion Food cravings of nutrition students differed between the phases of the menstrual cycle; however, with no difference in food intake and in anthropometric measures. Objetivo Verificar alterações de medidas corporais, consumo e desejos alimentares durante o ciclo menstrual de acadêmicas de nutrição. Métodos Estudo transversal com 27 estudantes de uma universidade pública do Mato Grosso do Sul, as quais tiveram seu consumo alimentar avaliado por meio de recordatório alimentar de 24 horas, estado nutricional avaliado com base em medidas antropométricas, e desejos alimentares avaliados utilizando-se o Questionário de Desejo Alimentar. Os dados foram coletados durante uma avaliação na fase folicular (entre o 5° e o 9° dia do ciclo menstrual) e outra na fase lútea (entre o 20° e o 25° dia do ciclo menstrual). Para as variáveis de consumo alimentar, utilizou-se o teste análise de variância (ANOVA, na sigla em inglês), seguido pelo teste de Tukey. Já para a análise dos desejos alimentares, utilizou-se o teste de Mann-Whitney. Foi considerado o nível de significância de 5% (p < 0,05). Resultados Os desejos por alimentos ricos em açúcar, sal e gordura, como chocolates, produtos de pastelaria, lanches e sobremesas foram maiores (p < 0,05) no momento pré-menstrual, apesar de não refletirem em maior consumo energético e tampouco em alteração na distribuição de macronutrientes. Observou-se maior consumo de carboidratos, proteínas, fibras e cálcio na fase lútea; no entanto, sem diferença estatística entre os grupos. Não foram encontradas diferenças no consumo de nenhum grupo alimentar, tampouco nas medidas antropométricas (p > 0,05). Conclusão Os desejos alimentares das acadêmicas de nutrição diferiram entre as fases; no entanto, sem diferença no consumo alimentar e nas medidas corporais. The idea for the present study and this specific analytical approach arose in a group discussion among Souza L. B. and Rodrigues Y. Analyses were planned and performed by Bomfim R. A. and Souza L. B. The first version of the manuscript was drafted by Souza L. B. and by Rafacho B. P. M., and then complemented with suggestions from all the other authors. Rodrigues Y. and Bomfim R. A. contributed to the development of the study protocol and data collection. All of the authors read and approved the final version of the manuscript to be submitted.

This study summarised the association between ultra-processed food (UPF) consumption and dental caries in children and adolescents through a systematic review and meta-analysis. The search of PubMed, Cochrane, Web of Science and Scopus databases using the ‘PECOS’ strategy retrieved 1462 eligible articles. Only studies with humans aged ≤ 19 years; that assessed groups of any UPF or specific UPF items; that measured dental caries as the decayed, filled and missing surfaces or teeth indexes, based on the WHO criteria; cross-sectional, case–control, cohort and all types of interventions that examined the adjusted association between UPF consumption and dental caries were included. All studies received qualitative evaluation. Meta-analysis using random-effects models combined multivariable-adjusted OR for case–control and cross-sectional studies and risk ratio (RR) for longitudinal studies of the highest v. lowest category of UPF consumption. Forty-two studies were included in the qualitative synthesis and twenty-seven in the meta-analysis. The pooled RR was 1·71 (95 % CI 1·31, 2·24), and the pooled OR was 1·55 (95 % CI 1·37, 1·75). The highest OR was found among participants who had dental caries prevalence >70 % (OR = 3·67, 95 % CI 2·16, 6·23). Better evidence quality was found among cohort studies that evaluated children <6 years old. The findings suggest that higher UPF consumption is associated with greater dental caries in children and adolescents. Public health efforts to reduce UPF consumption are needed to improve the oral health of children and adolescents.

Background: Little is known about the presence of two or more chronic conditions (multimorbidity) on tooth loss between adults and older adults.Understanding the mechanisms of multimorbidity on tooth loss is essential to inform policy development. This study aims to investigate the association between multimorbidity and severity of tooth loss in Brazilian adults and older adults.Methods: We analysed data from a nationally representative sample of 88,531 Brazilian individuals aged 18 and over who participated in the 2019 Brazilian Health Survey. Tooth loss was the outcome by two different classifications: functional dentition (lost 1–12 teeth) and severe tooth loss (lost 23–32 teeth). The presence of multimorbidity was the main exposure and based on 13 self-reported doctor-diagnosed chronic diseases that were further categorised into two groups, i.e., ≥2 or ≥ 3 comorbidities. Sociodemographic covariates included sex, age, race, income, level of education and tobacco smoking and geographic region of residency. Multivariate logistic regression models estimated the OR (Odds Ratios) and 95%CI of the associations between multimorbidity and tooth loss.Results: For 65,803 adults (aged 18 to 59), the presence of multimorbidity (≥2) was associated with 32% higher odds of having severe tooth loss (95% CI, 1.17; 1.49) and 33% lower odds of having functional dentition (95% CI, 0.60; 0.75). For the 22,728 older adults (aged 60 and older), multimorbidity (≥2) was associated with a 17% higher odds of severe tooth loss (95% CI, 1.06; 1.29) and 23% lower odds of having functional dentition (95% CI 0.70; 0.85). The sensitivity analysis, excluding hypertension, confirmed our findings.Conclusions: Brazilian adults and older adults with multimorbidity are more likely to have severe tooth loss and less likely to have functional dentition.
