“…A diminuição do excesso de peso na infância pode ser explicada pelo incentivo ao aleitamento materno, maiores taxas de escolaridade materna 24 e acesso a informação e educação sobre saúde, nutrição e dietética infantil. Já o aumento do excesso de peso é atribuído principalmente ao abandono precoce do aleitamento materno 25 , aumento da renda e maior disponibilidade de alimentos industrializados 26 , bem como a veiculação de propaganda de alimentos de alta densidade calórica e baixo valor nutricional 27 . Do mesmo modo, famílias cuja renda per capita foi maior que um salário mínimo apresentaram 2,5 vezes mais chance de excesso de peso.…”

“…Revisões sistemáticas sobre a associação entre peso ao nascer e excesso de peso na infância apontam que tanto crianças nascidas com baixo peso como as nascidas com peso elevado têm maiores probabilidades de apresentar obesidade na infância, mas essa chance é maior para aquelas nascidas com peso mais elevado 30,31 . Outro achado do presente estudo diz respeito ao tempo de amamentação exclusiva por menos de 5 meses, que embora não tenha entrado no modelo logístico final, apresentou razão de chances bruta para excesso de peso quase duas vezes maior em comparação aos que rece- 25 , e esses resultados demonstram a importância da atenção ao pré-natal e a vigilância em saúde e nutrição nos primeiros anos de vida.…”

Objective: To describe the prevalence of overweight, analyze its progression from 1989 to 2006 and identify factors associated with it among children younger than two years in Brazil.Methods: Data for the Women and Children National Demography and Health Survey (PNDS 2006) were collected using questionnaires and anthropometric measurements. The study sample included 1,735 children aged 0 to 24 months (910 boys; 825 girls). Nutritional status was defined according to the weight-for-height index (W/H; WHO, 2006), and children were classified as overweight if their W/H z score was greater than +2.Results: Prevalence of overweight in Brazil was 6.54%. The highest prevalence of overweight was found in the southern (10.0%) and midwestern (11.1%) regions, among families with a per capita income higher than one minimum wage (11.8%), in social classes with a greater purchasing power (9.7%), among children whose birth weight was greater than 3 kg (8.04%) and whose exclusive breastfeeding lasted less than five months (7.4%). According to a fitted multiple logistic regression model, factors associated with overweight were: birth weight ≥ 3 kg [odds ratio (OR) = 5.2, 95% confidence interval (95%CI) 2.56-10.56], per capita income ≥ 1 minimum wage (OR = 2.50, 95%CI 1.20-5.21), residence in midwestern region (OR = 2.40, 95%CI 1.01-5.72). Conclusions:The comparison of the prevalence found in the 2006 survey with the 1989 and 1996 values revealed that overweight among children younger than two years tends to decrease. The risk factors identified suggest that further actions should be conducted to prevent obesity among infants living in the midwestern region of Brazil, whose birth weight was greater than 3 kg and whose families had a per capita income higher than one minimum wage. Resultados: A prevalência de excesso de peso no país foi de 6,5%. Maiores prevalências foram observadas nas regiões Sul (10,0%) e Centro-Oeste (11,1%), nas famílias com renda per capita superior a um salário mínimo (11,8%), nas classes sociais de maior poder aquisitivo (9,7%), em crianças com peso ao nascer superior a 3 kg (8,04%) e com tempo de amamentação exclusiva inferior a 5 meses (7,4%). A regressão logística múltipla evidenciou como fatores associados: peso ao nascer ≥ 3 kg [odds ratio (OR) = 5,20; intervalo de confiança de 95% (IC95%) 2,56-10,56], renda per capita ≥ um salário mínimo (OR = 2,50; IC95% 1,20-5,21) e residir na macrorregião Centro-Oeste (OR = 2,40; IC95% 1,01-5,72). J Pediatr (Rio J) Conclusões:Comparando a prevalência de 6,5% encontrada no inquérito de 2006 com os anteriores de 1989 e 1996, evidencia-se que o excesso de peso em menores de 2 anos apresenta tendência de decréscimo. Os fatores de risco identificados apontam para a necessidade de intensificar ações de prevenção da obesidade junto aos lactentes residentes na Região Centro-Oeste, aos nascidos com mais de 3 kg e aos pertencentes a famílias com renda per capita superior a um salário mínimo.

“…We must consider the hypothesis set forth in previous studies that children whose mothers start working as early as the fourth month postpartum are weaned sooner and exposed earlier to foods consumed by the rest of the family, which makes them moresusceptible to overweight. 19 Furthermore, mothers who work outside the home tend to give their children treats and snacks, which are usually high in calories and of little nutritional value.…”

Objectives: To describe the prevalence of and factors associated with overweight in children under 4 years of age in Feira de Santana, state of Bahia, Brazil. Methods:Cross-sectional study nested within a birth cohort of 793 children born in Feira de Santana, Brazil. Independent variables were related to infant characteristics, social and demographic factors, maternal reproductive aspects, and diet of the child at age 4 months. The dependent variable was nutritional status, as assessed by weight-for-height ratio compared to Multicentre Growth Reference Study standards and obtained with the use of the software ANTHRO. Z scores of -2 and +2 above or below the median for the reference population were established as normality cutoff points. Child height and weight were measured with an anthropometer and digital scales, respectively; all measurements were taken in triplicate. The study was approved by the Research Ethics Committee of the Universidade Estadual de Feira de Santana (CEP/UEFS), under registration number 096/2006. Results:The prevalence of overweight was 12.5%. Adequate birth weight (RR 2.75; 95%CI 1.50-5.05), primiparity (RR 1.61; 95%CI 1.09-2.35), and maternal employment outside the home at age 4 months (RR 1.73; 95%CI 1.16-2.59) were associated with overweight. Conclusions:In this study, adequate birth weight, primiparity and maternal employment outside the home were associated with overweight in children. The rate of overweight found, which surpassed that reported by other studies conducted across the country (including Bahia), point to a risk of child obesity in Feira de Santana.J Pediatr (Rio J). 2010;86(4):311-316: Nutritional status, anthropometry, overweight.

“…Destarte, é preciso considerar a hipótese, apontada em estudos anteriores, de que as crianças cujas mães já trabalham no quarto mês após seu nascimento são mais precocemente desmamadas e introduzidas no consumo dos alimentos da família, estando mais susceptíveis ao sobrepeso 19 . Além disso, mães que trabalham fora do lar têm uma tendência de agradar os filhos com merendas, que na maioria das vezes apresentam alto valor calórico e baixo valor nutricional.…”
