Objective:To identify changes in traditional dietary behaviour through the evaluation of trends in bean consumption among adults in Brazil between 2007 and 2017 and to estimate its projections up to 2030.Design:Time-series analysis conducted with data from the Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey (Vigitel) between 2007 and 2017. Weekly consumption of beans was analysed. Prais–Winsten regression evaluated trends for the entire period of study (2007–2017) and in two periods of analyses (2007–2011 and 2012–2017) for the complete set of the population and stratified by socio-demographic characteristics. Estimated prevalence projections were calculated up to the year 2030 using its tendency from 2012 to 2017.Setting:Brazil.Participants:A probabilistic sample of 572 675 Brazilian adults aged ≥ 18 years.Results:Changes in traditional dietary pattern were identified. Regular consumption of beans (≥ 5 d/week) presented a stable prevalence trend for the total population in the complete and the first analysed period, but a significant decrease in the second half (67·5 % to 59·5 %) among both genders, all age groups and educational levels (except for ≥12 years). The higher magnitude of regular consumption of beans will occur up to the year of 2025 for the total population (46·9 %), when it will be less frequent in the week.Conclusion:Reductions in the weekly consumption of beans may represent the weakness of a traditional food culture in a globalised food system. By 2025, regular consumption of beans will cease to be the predominant habit in the country.

About one third of the most common cancers could be prevented by the reduction of modifiable behavioral risk factors. We aimed to identify behavioral patterns of risk and protective factors for cancer in Brazil, between 2014 and 2015. Data from Vigitel Survey (

RESUMO: Objetivos: Verificar a concordância entre autoimagem corporal (escala de silhuetas de Stunkard et al.) e estado nutricional e avaliar a satisfação corporal em indígenas khisêdjê do Parque Indígena do Xingu. Métodos: Estudo transversal que incluiu 131 indígenas khisêdjê, com 20 anos ou mais. Coletaram-se dados sobre imagem corporal, índice de massa corporal e perímetro da cintura. Foram utilizados a estatística kappa, o teste χ2 (p < 0,05), as razões de prevalências brutas e ajustadas e o teste t de Student. Resultados: As prevalências de sobrepeso e obesidade foram, respectivamente, 42 e 5,3%. A porcentagem de satisfação com o perfil corporal foi de 61,8%, sem diferença entre os sexos. Houve boa concordância entre autoimagem real e autoimagem ideal (p < 0,001), porém baixa concordância entre a autoimagem real e ideal e o estado nutricional para ambos os sexos. Maior prevalência de insatisfação corporal por excesso de peso foi detectada entre indivíduos com obesidade central e excesso de peso. Conclusão: Os resultados sugerem que a autoimagem corporal avaliada por meio da escala de silhuetas de Stunkard et al. tem pouca aplicabilidade como indicador do estado nutricional de indígenas khisêdjê do Parque Indígena do Xingu. ABSTRACT: Objective: To determine the agreement between body self-image (based on the Stunkard figure rating scale) and nutritional status and to evaluate body satisfaction among the Khisêdjê indigenous people of Parque Indígena do Xingu (Xingu Indigenous Park). Methods: A cross-sectional study involving 131 natives aged 20 and older. Data on body image, body mass index and waist circumference were collected. Kappa statistics, χ2 (p < 0.05), crude and adjusted prevalence ratios and Student’s t-test were used for data analysis. Results: The prevalence of overweight and obesity was respectively 42 and 5.3%. The percentage of satisfaction with body profile was 61.8% with no difference between the sexes. There was good agreement between actual and ideal self-image (p < 0.001), but poor agreement between actual and ideal self-image with nutritional status for both sexes. A higher prevalence of body dissatisfaction due to overweight was detected in individuals with central obesity and overweight. Conclusion: The results suggest that body self-image evaluated by the Stunkard silhouette scale has little applicability as an indicator of nutritional status among the indigenous Khisêdjê of Xingu Indigenous Park.

ObjectiveTo analyse trends in sweetened beverages consumption among adults in Brazil between 2007 and 2016.DesignA time-series analysis, with data from the Surveillance System of Risk and Protection Factors for Chronic Diseases by Telephone Survey (VIGITEL). The prevalence of regular consumption (≥5 d/week), the average daily consumption (millilitres) and the prevalence of non-consumption of these beverages were analysed. The temporal variations of the indicators were calculated by linear regression. The analyses were performed for the complete set of the evaluated population and stratified by sociodemographic characteristics.SettingBrazilian capitals and Federal District.SubjectsBrazilian adults aged ≥18 years (n 519 641).ResultsThere was a reduction in both regular and average daily consumption of sugar- and artificially sweetened beverages (−1·28 percentage points (pp)/year, P=0·001 and −9·63 ml/year, P=0·001, respectively). The same result regarding regular consumption was found when only sugar-sweetened beverages were analysed (−1·11 pp/year, P=0·011). Similar trends were identified in the stratified analyses, with a greater magnitude of reduction among males, young adults, those with higher schooling and residents of more developed regions. Coincidentally, there was an increase in the prevalence of adults who did not consume sweetened beverages (1·54 pp/year, P=0·005).ConclusionsThe consumption of sweetened beverages decreased during the period. However, a significant portion of the population still referred a daily consumption of these beverages.

ObjectiveTo describe trends in the prevalence of anaemia and Fe deficiency in children under 2 years of age living in a town in western Brazilian Amazonia.DesignTemporal analysis of two cross-sectional population-based surveys. Information on socio-economic status, morbidity and breast-feeding was obtained using a structured questionnaire. Child weight and length were measured for anthropometric evaluation. Concentrations of blood Hb, plasma ferritin and soluble transferrin receptor were measured.SettingThe town of Acrelândia, state of Acre, north-west Brazil.SubjectsA total of 170 and 224 participants of the 2003 and 2007 surveys, respectively.ResultsComparison between the 2003 and 2007 surveys revealed no statistically significant differences in the prevalence of anaemia (48 (95 % CI 39, 56) % to 40 (95 % CI 33, 47) %) or Fe-deficiency anaemia (39 (95 % CI 30, 48) % to 37 (95 % CI 30, 45) %), respectively. However, an increase in the overall prevalence of Fe deficiency from 62 (95 % CI 51, 68) % to 81 (95 % CI 75, 86) % was observed (χ2 test, P ≤ 0·001). In age- and sex-adjusted analyses for risk of Fe deficiency, only early introduction of cow's milk (ConclusionsNo improvements were observed in the prevalence of anaemia, exposing a worrying scenario for public health, while a significant increase was found in the prevalence of Fe deficiency in the studied infants and toddlers.

Introdução: O panorama nutricional da infância brasileira nas últimas décadas caracteriza-se por tendência ao declínio da prevalência da desnutrição com manutenção da prevalência de anemia, principalmente a ferropriva. Contudo, desigualdades regionais ainda persistem especialmente na região norte do país. A substituição precoce e inadequada do aleitamento materno por outros alimentos tem sido considerada principal responsável pelas deficiências nutricionais entre menores de dois anos. Objetivo: Caracterizar a evolução das práticas de aleitamento materno, prevalências de anemia, deficiência de ferro e desnutrição em crianças menores de 2 anos em área urbana de Acrelândia, Estado do Acre. Métodos: Análise temporal de dois inquéritos transversais de base populacional realizados em 2003 (n= 170) e 2007 (n= 224). Informações sobre condições socioeconômicas, morbidade e aleitamento materno foram obtidas por meio de questionário estruturado. Peso e comprimento das crianças foram medidos pela equipe de pesquisa, sendo considerada desnutrida a criança cujo indicador de altura para idade encontrava-se abaixo de 2 escores z, segundo padrão da Organização Mundial da Saúde (OMS). Avaliaram-se as concentrações de hemoglobina sanguínea (maiores de 6 meses de idade), ferritina e receptor de transferrina plasmáticos para diagnóstico de anemia e deficiência de ferro segundo critérios da OMS. Resultados: Na comparação entre os inquéritos 2003 e 2007, não houve diferenças estatisticamente significantes nas prevalências (intervalo com 95 por cento de confiança) de aleitamento materno total de 46 por cento (39 por cento -54 por cento ) para 53 por cento (46 por cento -59 por cento ), aleitamento materno exclusivo em menores de 6 meses de 23 por cento (10 por cento -41 por cento ) para 16 por cento (6 por cento -34 por cento ), desnutrição de 9 por cento (5 por cento -14 por cento ) para 11 por cento (8 por cento -16 por cento ), anemia de 48 por cento (39 por cento -56 por cento ) para 40 por cento (33 por cento -47 por cento ) e anemia ferropriva de 36 por cento (28 por cento -45 por cento ) para 36 por cento (29 por cento -44 por cento ), respectivamente. No entanto, houve aumento na prevalência de deficiência de ferro de 62 por cento (53 por cento -70 por cento ) para 81 por cento (75 por cento -86 por cento ) (teste do c2, p0,001). Conclusão: A presente análise não observou melhorias na prática de aleitamento materno total e exclusivo e na ocorrência de anemia no período analisado, revelando um cenário preocupante para saúde pública com aumento significativo da prevalência de deficiência de ferro nas crianças estudadas Introduction: The nutritional picture of Brazilian infancy in recent decades is characterized by a downward trend in the prevalence of malnutrition and unchanged prevalence of anemia, especially iron deficiency anemia. However, regional inequalities persist, particularly in the North of the country. The early and inadequate introduction of foods has been considered the main factor responsible for nutritional deficiencies among children younger than two years of age. Objective: To characterize trends in breastfeeding practices and the prevalence of anemia, iron deficiency and malnutrition, among children younger than 2 years of age, in an urban area of Acrelandia, Acre State. Methods: Temporal analysis of two cross-sectional population-based surveys conducted in 2003 (n = 170) and 2007 (n = 224). Information on socioeconomic status, morbidity, and breastfeeding were obtained using a structured questionnaire. Child weight and length were measured by the research team and children whose height for age indicator was below -2 z-scores were considered malnourished, according to World Health Organization standards (WHO). Blood hemoglobin (in children older than 6 months), as well as plasma ferritin and soluble transferrin receptor concentrations were evaluated to screen for anemia and iron deficiency, according to WHO criteria. Results: Comparison between the 2003 and 2007 surveys revealed no statistically significant differences in the prevalence (95 per cent confidence intervals) of breastfeeding: 46 per cent (39 per cent -54 per cent ) to 53 per cent (46 per cent - 59 per cent ), exclusive breastfeeding in infants younger than 6 months of age: 23 per cent (10 per cent - 41 per cent ) to 16 per cent (6 per cent -34 per cent ), malnutrition: 9 per cent (5 per cent - 14 per cent ) to 11 per cent (8 per cent - 16 per cent ), anemia:48 per cent (39 per cent - 56 per cent ) to 40 per cent (33 per cent - 47 per cent ) or iron deficiency anemia: 36 per cent (28 per cent - 45 per cent ) to 36 per cent (29 per cent - 44 per cent ), respectively. However, an increase in the prevalence of iron deficiency from 62 per cent (53 per cent - 70 per cent ) to 81 per cent (75 per cent - 86 per cent ) was observed (c² test, p 0.001). Conclusion: In the analyzed period, no improvements were observed in the prevalence of total and exclusive breastfeeding or in the occurrence of anemia, exposing an worrying scenario for public health, with a significant increase in the prevalence of iron deficiency in the studied infants and toddlers
