RESUMO
OBJECTIVE: To explore the internal structure and analyze evidence of measurement invariance of the Sisvan form of food intake markers of the Food and Nutrition Surveillance System (Sisvan) for children aged six to 23 months. METHODS: Sisvan microdata from 2015 to 2019 were used. After analyzing sample adequacy, exploratory factor analysis was carried out considering factor loadings (≥ 0.30 and < 0.85), communality (> 0.20), model fit indices - Tucker-Lewis index (TLI) > 0.90, and root mean square error of approximation (RMSEA) < 0.08. A critical analysis of the form items was performed to adjust the parameters. Measurement stability was investigated between age groups, macro-regions and longitudinally by multi-group confirmatory factor analysis in configural, metric, and scalar invariance models. Configural invariance was accepted if RMSEA < 0.08 and TLI and comparative fit index (CFI) > 0.90. Metric and scalar invariances were accepted if ΔRMSEA < 0.015 and ΔCFI < 0.01, compared to the previous model. RESULTS: After critical analysis, items were grouped (vegetables and leafy greens; meat or eggs and liver) and excluded (salty food; porridge with milk; rice, potatoes, yams, cassava, flour, or pasta). The exploratory model comprised three factors: healthy complementary feeding (fruit; vegetables; orange or dark green leafy vegetables or fruits; meat, offal, or egg; beans), ultra-processed (yogurt; hamburger and/or sausages; sweetened drinks; instant noodles, packet snacks, or salty cookies; sandwich cookies, sweets, or treats), and milk feeding (breast milk; other milk), with satisfactory factor loadings, communalities and fit (TLI: 0.918, RMSEA: 0.071). The reformulated instrument was stable in the invariance models tested. CONCLUSIONS: With the incorporation of the modifications to the Sisvan form, the food intake markers subsidize a more adequate interpretation of the feeding situation of children aged six to 23 months.

RESUMO OBJETIVOS Explorar a estrutura interna e analisar evidências de invariância de mensuração do formulário de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) para crianças de seis a 23 meses. MÉTODOS Utilizaram-se microdados do Sisvan de 2015 a 2019. Após análise de adequação da amostra, realizou-se análise fatorial (AF) exploratória considerando valores de cargas fatoriais (≥ 0,30 e < 0,85), comunalidade (> 0,20) e índices de ajuste do modelo - índice de Tucker-Lewis (TLI) > 0,90 e raiz do erro quadrático médio de aproximação (RMSEA) < 0,08. Empreendeu-se uma análise crítica aos itens do formulário para adequação dos parâmetros. A estabilidade de mensuração foi investigada entre grupos etários, macrorregiões e longitudinalmente por AF confirmatória multigrupo em modelos de invariância configural, métrica e escalar. A invariância configural foi aceita se RMSEA < 0,08 e TLI e índice de ajuste comparativo (CFI) > 0,90. Invariâncias métrica e escalar foram aceitas se ΔRMSEA < 0,015 e ΔCFI < 0,01, comparando-se ao modelo anterior. RESULTADOS Após análise crítica, itens do formulário foram agrupados (legumes e verduras; carnes ou ovos e fígado) e excluídos (comida de sal; mingau com leite; arroz, batata, inhame, mandioca, farinha ou macarrão). O modelo exploratório compreendeu três fatores: alimentação complementar saudável (frutas; hortaliças; vegetal ou fruta alaranjados ou folhas verdes escuras; carnes, vísceras ou ovo; feijão), ultraprocessada (iogurte; hambúrguer e/ou embutidos; bebidas adoçadas; macarrão instantâneo, salgadinhos de pacote ou biscoitos salgados; biscoito recheado, doces ou guloseimas), e láctea (leite do peito; outro leite), com cargas fatoriais, comunalidades e ajuste satisfatórios (TLI: 0,918, RMSEA: 0,071). O instrumento reformulado foi estável nos modelos de invariância testados. CONCLUSÕES Com a incorporação das modificações ao formulário do Sisvan, os marcadores subsidiam uma interpretação mais adequada da situação alimentar de crianças de seis a 23 meses.

OBJECTIVE: To investigate the effectiveness of a training program for health workers regarding infant feeding practices to reduce sugar consumption in children. DESIGN: A cluster randomized trial was conducted at 20 health centers in southern Brazil randomly assigned to an intervention (nâ¯=â¯9) or control (nâ¯=â¯11) group. PARTICIPANTS: The 715 pregnant women enrolled were assessed when their children were aged 6 months, 3 years, and 6 years. INTERVENTION: A training session for primary care workers based on the Brazilian National Guidelines for Children. MAIN OUTCOME MEASURE: Mothers were asked when sugar was first offered to children. Added sugars intake was obtained from dietary recalls. ANALYSIS: The effectiveness of the intervention was modeled using generalized estimation equations and Poisson regression with robust variance. RESULTS: Children attending intervention health centers had a 27% reduced risk of sugar introduction before 4 months of age (relative risk, 0.73; 95% confidence interval [CI], 0.61-0.87) as well as lower added sugars consumption (difference, -6.36 g/d; 95% CI, -11.49 to -1.23) and total daily energy intake (difference, -116.90 kcal/d; 95% CI, -222.41 to -11.40) at 3 years of age. CONCLUSIONS AND IMPLICATIONS: Health care worker training in infant feeding guidelines may be an effective intervention to delay the introduction of added sugars and lower the subsequent intake of added sugars in infants and toddlers.

OBJECTIVE: The aim of this study is to assess the impact of health worker training on infant feeding practices on the prevalence of functional constipation (FC) among children at 6 years of age. METHODS: Cluster randomized field trial conducted in Porto Alegre, Brazil. Health centers were randomly allocated into intervention (nâ=â9) or control (nâ=â11) groups. In intervention sites, health workers joined training sessions on the "Ten Steps for Healthy Feeding for Children from Birth to Two Years of age". Pregnant women in the last trimester of both groups were identified, invited to participate and enrolled in the study as the potential mothers to receive the dietary counseling provided by the health workers. At 6 years of age, the prevalence of FC was evaluated based on Rome III, defined by 2 or more of the following: infrequent defecation, fecal incontinence, history of retentive posturing, or/and history of painful defecation. RESULTS: Among 387 mother-child pairs (206 intervention, 181 control) evaluated at 6 years of age, the prevalence of FC was lower in the intervention group compared with the control group (15.0% vs 23.9%, respectively). The probability of being constipated was 38% lower in the intervention group (PRâ=â0.62; 95% CI 0.44-0.87; Pâ<â0.01). CONCLUSION: The health workers training to promote the "Ten Steps" was an effective way to reduce the prevalence of constipation among children at 6 years of age.
