Objective: To compare the prevalence rates of nutritional deviations in children under five years of age according to data from the Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN) and those obtained by trained anthropometrists.
Methods: This is a descriptive cross-sectional study based on data from 10 municipalities and 2 sources: i) SISVAN Web (secondary database) and ii) an investigation that evaluated the implementation of food and nutrition actions in the Family Health Strategy in the state of Paraíba (primary database), with 24,137 and 897 individuals, respectively. Proportions of overweight - according to weight/age (W/A), weight/height (W/H), and body mass index/age (BMI/A) - and stunting - according to the height/age (H/A) index - based on classifications of SISVAN Web and those obtained by trained anthropometrists were compared using the two-proportion Z-test.
Results: Frequencies of overweight, according to W/A (10.0 vs. 7.8%), W/H (17.2 vs. 14.3%), and BMI/A (18.1 vs. 14.4%), as well as stunting (12.3 vs. 8.6%), were higher on data from SISVAN Web than on those obtained by trained anthropometrists, and the differences were significant.
Conclusions: The findings point to distortions in the nutritional classification of children under five years of age monitored by SISVAN Web.

Article Synopsis
- Preterm, low-birth weight (LBW), and small-for-gestational age (SGA) newborns are at increased risk for poor health outcomes, impacting their growth trajectories.
- The study examines growth patterns and recovery in the first 5 years of life among these vulnerable groups using extensive data from Brazil, focusing on height/length-for-age and weight-for-age z-scores.
- Findings indicate that while growth recovery begins around 12 months for term infants, preterm infants lag, especially females, with significant catch-up growth occurring later for males between 24-59 months, revealing distinct recovery dynamics based on vulnerability phenotype.

The aim of the present study was to estimate the population coverage of recording food intake markers in Brazil's Food and Nutrition Surveillance System (Sisvan) and mean annual percent change (APC) in coverage according to the system used for data entry (e-SUS APS and Sisvan Web). We conducted an ecological time series study of the period 2015-2019. The data were stratified into region and age group.
