Trends in the nutritional status among children from 2008 to 2015: Food and Nutrition Surveillance System (Sisvan)

Abstract Background The Food and Nutrition Surveillance System (Sisvan) is a national and essential System to monitor the growth and development of children in Primary Health Care services. Objective To describe the coverage and temporal trend of the nutritional status of children aged 5 to 9 registered in Sisvan between 2008 and 2015. Method Simple linear regression analysis was performed to verify the temporal trend in the number of records, coverage, and nutritional status classification among children from 5 to 9 years old in four territories (Dourados, Mato Grosso do Sul, Midwest region and Brazil). Results There was a rising trend in the number of records, except for Dourados that presented irregular patterns (p=0.123). Underweight and normal weight presented falling trends, while overweight and obesity increased in the period in the territories evaluated, except for Dourados, which did not present significant results for normal weight (p=0.145) and obesity (p=0,318). Conclusion The number of records and, consequently, the coverage of Sisvan increased significantly in three territories evaluated in the period. Results of the nutritional status strengthen the nutritional transition process experienced in Brazil.
