[Time-series analysis of the consumption of sweetened soft drinks among adults in Brazil: 2007 to 2014]. / Análise de série temporal do consumo de bebidas açucaradas entre adultos no Brasil: 2007 a 2014.

The scope of this article is to analyze the time-series trend and factors associated with the consumption of soft drinks or packaged fruit juices among adults in Brazil. It is a study based on secondary data from the System of Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey conducted among Brazilian adults between 2007 and 2014. The consumption frequency and intensity (number of cups or cans per week) of soda or packaged juice was checked. Socio-demographic and behavioral data were the independent variables. The time-series trend of annual consumption was evaluated by means of Linear Regression. The factors (age, sex, region, work, schooling and TV screen time) associated with the consumption of these beverages were investigated by Poisson regression. There was a 32.7% reduction in soft drink or packaged juice consumption between 2007 and 2014. Factors associated with higher consumption were: male sex (p = 0.000); 18-29 year-age-range (p = 0.000); residence in the central-west, southeast and southern regions (p = 0.000); lower schooling (p = 0.616); being employed (p = 0.007) and more than 3 hours of TV screen time per day (p = 0.000). The analyses describe a downward trend in the consumption of soda or packaged fruit juice among adults in Brazil from 2007 to 2014.

O objetivo deste artigo é analisar a tendência temporal e os fatores associados ao consumo de refrigerante ou suco artificial entre adultos no Brasil. Estudo desenvolvido a partir de dados secundários do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico, realizado com adultos brasileiros entre 2007-2014. Foi verificada a frequência e a intensidade do consumo (quantidade de copos ou latas por semana) de refrigerante ou suco artificial. Dados sociodemográficos e comportamentais foram as variáveis independentes. A tendência temporal do consumo anual foi avaliada por meio de Regressão Linear. Os fatores associados (idade, sexo, região, trabalho, escolaridade, hábito de assistir TV) ao consumo dessas bebidas foram investigados por Regressão de Poisson. Houve redução de 32,7% do consumo de refrigerante ou suco artificial entre 2007 e 2014. Os fatores associados ao maior consumo foram: sexo masculino (p = 0,000); faixa etária de 18-29 anos (p = 0,000); residência nas regiões centro-oeste, sudeste e sul (p = 0,000); menor escolaridade (p = 0,616); estar empregado (p = 0,007) e assistir TV mais de 3 horas por dia (p = 0,000). As análises descrevem uma tendência de queda no consumo de refrigerante ou suco artificial entre os adultos no Brasil de 2007 a 2014.

Weight gain and changes in nutritional status of Brazilian adults after 20 years of age: a time-trend analysis (2006-2012). / Ganho de peso e mudança do estado nutricional de brasileiros após os 20 anos de idade: uma análise de série temporal (2006-2012).

OBJECTIVE: To analyze weight gain (WG) and change in nutritional status (NS) after the age of 20 years in the Brazilian adult population between 2006 and 2012. METHODS: Time series using seven surveys from the Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey (VIGITEL). The analyses were stratified by region, age, sex and education, considering the sampling weights and complex design. In addition, relative weight change (RWC) in the period was determined for each category of independent variables using linear regression models. RESULTS: Analyses showed an increase in WG after 20 years in two vectors: by survey year and age group, where the increase was higher in women. From 2006 to 2012, individuals 25-29 years old (women: RWC = 70%; ßyear = 0.54 kg/year) and 30-34 years old (women: RWC = 56%; ßyear = 0.57 kg/year) showed greater RWC. In 2012, the higher WG occurred in the age groups of 21-24 and 25-29 years old. Regarding the change in NS, individuals who were overweight at 20 years had a higher probability of remaining in this condition (or shifting to obesity) over time. However, among those who had a normal weight, the probability of not becoming overweight or obese was > 80%, independently of sex. CONCLUSION: The Brazilian population displayed progressive WG in adulthood, especially in the first decade after the age of 20, in addition to the period effect. On the other hand, individuals with normal weight in their 20s tended to maintain the same condition.

Ganho de peso e mudança do estado nutricional de brasileiros após os 20 anos de idade: uma análise de série temporal (2006-2012) / Weight gain and changes in nutritional status of Brazilian adults after 20 years of age: a time-trend analysis (2006-2012)

RESUMO: Objetivos: Analisar o ganho de peso (GP) e a mudança do estado nutricional (EN) após os 20 anos de idade na população brasileira entre os anos de 2006 e 2012. Metodologia: Série temporal com base em sete inquéritos transversais do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL). As análises foram estratificadas por região, faixa etária, sexo e escolaridade, considerando-se o plano e a ponderação amostral. Ainda, estimou-se a variação ponderal relativa (VPR) no período para os estratos analisados por meio de modelos de regressão linear. Resultados: Identificaram-se dois vetores de aumento no GP após os 20 anos de idade: ano do inquérito e faixa etária, que foram mais expressivos entre as mulheres. Entre 2006 e 2012, as faixas etárias que apresentaram a maior variação temporal foram de 25-29 (mulheres: VPR = 70%; βano = 0,54 kg/ano) e 30-34 anos (mulheres: VPR = 56%; βano = 0,57 kg/ano). Em 2012, o maior aumento de GP ocorreu nas faixas etárias de 21-24 e 25-29 anos. Quanto à mudança de EN, indivíduos que apresentavam excesso de peso aos 20 anos tiveram maior probabilidade de permanecer nessa condição (ou migrar do sobrepeso para obesidade) com o avançar da idade. Contudo, entre os que eram eutróficos, a probabilidade de permanecer com o mesmo EN foi > 80%, independentemente do sexo. Conclusão: Além do efeito do tempo, a população brasileira apresentou progressivo GP no decorrer da fase adulta, sobretudo na primeira década após os 20 anos. Por outro lado, indivíduos eutróficos aos 20 anos tenderam a permanecer nessa condição.

[Temporal trend and factors associated with consumption of fatty meats by the Brazilian population between 2007 and 2014]. / Tendência temporal e fatores associados ao consumo de carnes gordurosas na população brasileira entre de 2007 a 2014.

The scope of this article is to analyze the temporal trend of the consumption of fatty meats and factors associated with the consumption thereof between 2007 and 2014. A time series of fatty meat consumption (red meat and chicken) was conducted by the "Surveillance of Risk and Protection Factors for Chronic Diseases (Vigitel) telephone survey." The consumption trend was analyzed by joinpoint regression and expressed in annual percentage variation (VPA [95% CI]), while sociodemographic and behavioral factors were associated in 2007 and 2014 by the generalized linear (log-binomial) model. Between 2007 and 2014, white meat consumption ≥ 5x/ week increased (VPA 6.9% [5.7, 8.1]), while red meat consumption remained stable. Fatty meat consumption showed a significant reduction as of 2011 (VPA -4% [-7.5; -0.2]), probably due to the reduction in the consumption of fatty red meats. It was found that males, of younger age groups living in the center-west/south-east/south regions, with low education level and alcohol and tobacco abuse were associated with fatty meat consumption; while watching television>3hours/day was only associated in 2014. The consumption of fatty meats showed a reduction trend in the Brazilian population, and its consumption was associated with sociodemographic and behavioral variables.

O objetivo deste artigo é analisar a tendência temporal do consumo de carnes gordurosas (CG) e fatores associados ao seu consumo habitual entre 2007 e 2014. Série temporal do consumo de CG (vermelha e frango/galinha) realizada a partir do inquérito telefônico "Vigilância de Fatores de Risco e Proteção para Doenças Crônicas" (Vigitel). A tendência do consumo foi analisada por regressão "joinpoint" e expressa em variação percentual anual (VPA[IC95%]), enquanto os fatores sociodemográficos e comportamentais associados em 2007 e 2014 por modelo linear generalizado (log-binomial). Entre 2007-2014, o consumo ≥ 5x/semana de carnes brancas aumentou (VPA 6,9% [5,7; 8,1]), enquanto as vermelhas permaneceu estável. O consumo CG apresentou redução significativa a partir de 2011 (VPA -4,0%[-7,5; -0,2]), provavelmente em função da redução no consumo das vermelhas gordurosas. Identificamos que o sexo masculino, as faixas etárias mais jovens, residir nas regiões CO/SE/S, escolaridade ≤ 8 anos e o uso abusivo de álcool e tabaco se associaram com o consumo de CG; assistir televisão > 3h/dia foi associada apenas em 2014. No período analisado houve redução no consumo de CG pela população brasileira, sendo seu consumo associado a fatores sociodemográficas e outros comportamentos promotores de DCNT.
