title: [Food and Nutritional Surveillance System (SISVAN) in children from Rio Grande do Sul State, Brazil: coverage, nutritional status, and data reliability].
abstract: This study aimed to evaluate: the coverage of the Food and Nutritional Surveillance System (SISVAN) in the State of Rio Grande do Sul, Brazil, and it Regional Health Offices in 2006; the nutritional status of children 0-10 years of age; and the reliability of data on nutritional status recorded in the system. A cross-sectional descriptive study was conducted with secondary data on 63,320 children. Coverage was defined as the proportion of children younger than 10 years covered by the Family Health Strategy in the State's various municipalities (counties). Height-for-age (H/A) and body mass index for age (BMI/A) were classified according to World Health Organization (WHO) criteria. Agreement between the nutritional classifications recorded in the system and those calculated in this study was evaluated with the weighted kappa coefficient (at 5%). The system's coverage in the State of Rio Grande do Sul was 10.5%. Low height-for-age was found in 7.1% of children and overweight in 8.4%. Agreement between the classifications showed a kappa coefficient of 0.43. The system's coverage and agreement between classifications were both low, and the study showed the coexistence of high overweight and stunting rates in this age group.
