Sistema De Vigilância Alimentar E Nutricional: Utilização E Cobertura Na Atenção Primária.

Resumo Objetivos: analisar o estado nutricional e a tendência temporal da cobertura de adolescentes brasileiros acompanhados no Sistema de Vigilância Alimentar e Nutricional no período de 2008-2019. Métodos: estudo ecológico de séries temporais com dados do SISVAN coletados no período de 2008 a 2019 com 45.869.266 de registos. Foram coletados dados de índice de massa corporal e calculadas as coberturas dos registros dos adolescentes acompanhados pelo sistema. Estimou-se a percentagem da variação anual da cobertura e estado nutricional pela regressão de Prais-Winsten, com nível de significância de 5%. Resultados: observa-se crescimento da prevalência de obesidade entre 2008 a 2019, nesse período a magreza manteve-se estável no Brasil. A cobertura nacional evoluiu de 9,3% em 2008 para 19,6% em 2019, com variação anual de 9% e tendência de aumento estatisticamente significativa. No Brasil, a obesidade nessa faixa etária apresentou um aumento entre os anos de 2008 e 2019, com uma variação anual de 8,7% (IC95%= 7,8-9,6). Conclusão: modificações observadas no estado nutricional sugerem a ocorrência da transição nutricional na população de adolescentes. O percentual de cobertura disponível no sistema tem potencial de crescimento, entretanto, o atual cenário impacta em possível análise insuficiente para subsidiar a elaboração e reorientação de políticas públicas.

Estado nutricional e tendência temporal da cobertura de adolescentes brasileiros acompanhados no Sistema de Vigilância Alimentar e Nutricional, 2008 a 2019

“…26 The main obstacles on high coverage and the use of SISVAN by primary care are: lack of human resources, physical structure and logistics; complexity of implementation; poor management and little political engagement, and problems with the matrix support for the teams responsible for supplying the system. 27 In a study carried out in Natal, capital of Rio Grande do Norte, health professionals working with the PSE reported that the biggest difficulties were the lack of material and financial resources (50.5%), intersectorial disarticulation (26.7%), and followed by the excess of activities in the work process (17.1%). 28 Similarly, in a study conducted in the cities of the Superintendência Regional de Saúde de Belo Horizonte (Regional Superintendence of Health in Belo Horizonte), the main problems faced in the cities regarding data collection for food and nutritional surveillance and data entry in SISVAN Web were: problems with the internet (62.2%); lack of training for data collection (54.1%); professional turnover (51.4%) and extensive user's registration form in the system (51.4%).…”

Nutritional status and temporal trend of coverage of Brazilian adolescents monitored in the Food and Nutritional Surveillance System, 2008 to 2019

Oliveira,

Vieira

et al. 2023

Objectives: to analyze the nutritional status and temporal trend of the coverage of Brazilian adolescents monitored in the Food and Nutritional Surveillance System in the period 2008-2019. Methods: ecological study of temporal series with SISVAN data collected from 2008 to 2019 with 45,869.266 registration. Body mass index data were collected and the registration coverage of adolescents monitored by the system was calculated. The percentage of annual variation in coverage and nutritional status was estimated using Prais-Winsten regression, with a significance level of 5%. Results: an increase in the prevalence of obesity was observed between 2008 and 2019, during this period thinness remained stable in Brazil. National coverage evolved from 9.3% in 2008 to 19.6% in 2019, with an annual variation of 9% and a statistically significant increase trend. In Brazil, obesity in this age group increased between 2008 and 2019, with an annual variation of 8.7% (CI95% = 7.8-9.6). Conclusion: modifications were observed in nutritional status suggest the occurrence of nutritional transition in the adolescents’ population. The percentage of coverage available in the system has growth potential, however, the current scenario impacts on a possible insufficient analysis to support the elaboration and reorientation of public policies.

“…8 The Sistema de Vigilância Alimentar e Nutricional (SISVAN) (Food and Nutrition Surveillance System) can be used to support early prognosis, 9 because it is a relevant source to promote greater assertiveness in planning actions and assist in the development of nutrition and food activities for the population assisted in local, state, and federal levels. 10 In this context, it is important to analyze aspects related to children's health for a better elaboration of strategies and early health policies, 11 especially regarding eating habits and nutritional status. The recognition of the importance of breastfeeding for nutritional status in childhood and the relevance of adequate coverage of SISVAN to support the diagnosis of food and nutritional status at childhood 12 justify this investigation.…”

Trend and correlation of obesity and continued breastfeeding in children from six to 3 months old

et al. 2023

Objectives: to analyze the trend and correlation of obesity and the increase in continued breastfeeding in children aged six to 23 months in Brazil, from 2015-2019. Methods: ecological time series study with data from the Sistema de Vigilância Alimentar e Nutricional (Food and Nutritional Surveillance System). The dependent variable was the prevalence of obesity. Prais-Winsten linear regression was used to verify the trend. Spearman’s correlation was used to verify the relationship between the prevalence of obesity and the increase in continued breastfeeding. Results: there was a trend towards a reduction in the prevalence of obesity in all regions in Brazil (Annual Percentage Variation [APV]: -4.14; CI95%=-4.50; -3.79). The prevalence of continued breastfeeding showed an upward trend in the North (APV=4.89; CI95%=2.92; 6.90), Southeast (APV=3.36; CI95%=2.32; 4 .41) and South (APV=2.67; CI95%=0.98; 4.38). There was a negative and significant correlation between obesity and continued breastfeeding in the North, Northeast, Southeast and South regions. Conclusion: the reduction in the prevalence of obesity and the increase in continued breastfeeding occurred only in some regions, requiring the implementation of effective strategies to be present throughout the country. Actions to promote, protect and support continued breastfeeding and healthy eating should be more prioritized to promote the child’s healthy growth.
