This study aimed to assess factors associated with anemia in schoolchildren. All subjects (N = 1,013; age 7-14 yrs.) p = 0.020 and OR < 50% adequacy = 1.68; p = 0.016) and family income below 1 minimum wage (OR = 1, 42; p = 0.035). Anemia prevalence in children and adolescents was high, especially among the poorest subjects and those with low intake of bioavailable iron.
OBJETIVO: Analisar a alimentação complementar de crianças nos primeiros dois anos de vida. MÉTODOS: Este é um estudo transversal, com amostra constituída de 724 crianças residentes na cidade de Salvador, BA, Brasil, elegíveis por meio de amostragem por conglomerados em três estágios. As informações referentes ao consumo alimentar foram coletadas por meio do inquérito recordatório de 24 horas e processadas pelo programa Virtual Nutri. O pacote estatístico STATA, que incorpora o efeito da ponderação, foi utilizado para realizar as análises estatísticas. RESULTADOS: Observou-se que o desmame é praticado precocemente. O consumo de leite materno declina expressivamente a partir dos seis meses de idade, e é substituído pelas fórmulas à base de leite em pó integral, espessante e açúcar. A participação dos hidratos de carbono no valor calórico total da dieta aumenta com a idade, enquanto que o lipídeo diminui expressivamente. A distribuição média da energia e da proteína da dieta está acima do recomendado segundo a idade para todos os grupos etários, mas é grande a variabilidade do consumo intragrupo. A realização do desjejum, do almoço e do jantar foi registrada para aproximadamente 90% das crianças investigadas. CONCLUSÃO: A iniciação do consumo de alimentos complementares acontece em período bem precoce da vida, e são oferecidos em quantidade insuficiente para suprir as recomendações nutricionais, particularmente de micronutrientes.

Obesity prevalence is increasing worldwide, with inadequate nutrition and physical inactivity as the main risk factors. The objective was to evaluate the impact of a nutritional intervention and physical activity program on body mass index (BMI) and waist circumference (WC) in adult women. This quasi-experimental study, lasting 12 months, enrolled 69 adult women that reported physical activity three times a week, besides receiving nutritional counseling and lectures on healthy living, evaluated at baseline and at 6 and 12 months of follow-up. Lower levels of physical activity and higher intake of high-risk foods were associated with a 2.28 cm increase in mean WC, has compared to higher physical activity and lower intake of high-risk foods (p < 0.01). Lower levels of physical activity associated with high intake of protective foods increased the mean BMI by 0.68 kg/m(2), as compared to higher physical activity and high intake of protective foods. The intervention was positively associated with the target parameters.
Estudo transversal, envolvendo 2.001 crianças das áreas rural e urbana de dez municípios da Bahia, Brasil. Avalia-se a relação entre os gradientes da desigualdade e os fatores do ambiente familiar, de saúde e nutrição, utilizando-se a regressão logística multinomial multivariada. As crianças do tercil intermediário das condições de vida e aquelas do tercil mais pobre têm chances significantes e crescentes de viverem na área rural, em domicílio chefiado pela mulher, ter o pai desempregado, mãe com baixa escolaridade, de dormir com mais de uma pessoa na mesma cama, déficit linear grave e consumir retinol abaixo da mediana. A existência de mais de uma criança no domicílio, ser portadora de déficit ponderal e ter o consumo de lipídeo abaixo da mediana foram eventos também significantes para as crianças mais pobres. A anemia foi identificada entre as crianças do tercil intermediário. A desigualdade expõe as crianças a chances crescentes de inadequado estado de saúde e nutrição. Políticas de saúde podem implementar medidas emergenciais no sentido de minimizar os males impostos pela desigualdade à saúde e nutrição na infância.
The relationship between breastfeeding and the loss of weight gained during pregnancy remains unclear. This study aimed to investigate the association between breastfeeding and maternal weight changes during 24 months post-partum. We studied a dynamic cohort comprising 315 women living in two cities in the state of Bahia, Brazil. The outcome variable was change in the post-partum weight; the exposure variable was the duration and intensity of breastfeeding. Demographic, socio-economic, environmental, reproductive and lifestyle factors were integrated in the analysis as covariates. The data were analysed using multiple linear regression and linear mixed-effects models. The average cumulative weight loss at 6 months post-partum was 2.561 kg (SD 4.585), increasing at 12 months (3.066 kg; SD 5.098) and decreasing at 18 months (1.993 kg; SD 5.340), being 1.353 kg (SD, 5.574) at 24 months post-partum. After adjustment, the data indicated that for every 1-point increase in breastfeeding score, the estimated average post-partum weight loss observed was 0.191 kg at 6 months (P = 0.03), 0.090 kg at 12 months (P = 0.043), 0.123 kg at 18 months (P < 0.001) and 0.077 kg at 24 months (P = 0.001). Based on these results, we concluded that despite the low expressiveness, the intensity and duration of breastfeeding was associated with post-partum weight loss at all stages of the study during the 24-month follow-up.
OBJECTIVE:To identify determinants of protein-energy malnutrition resulting in weight and linear growth deficits in children.
METHODS:A cross-sectional study was carried out among 1,041 children (under two years of age) from 10 municipalities in Bahia, Northeastern Brazil, during 1999-2000. Both logistic regression and a hierarchical approach were used to identify factors associated with the anthropometric measures.
RESULTS:The basic determinant found in the final model for linear growth retardation was having up to two household appliances (OR=2.9; 95% CI: 1.74-4.90); as an underlying determinant, not attending prenatal visits (OR=2.7; 95% CI: 1.47-4.97); and, among immediate determinants were low birth weight (OR=3.6; 95% CI: 1.72-7.70) and reported hospitalization within 12 months before the interview (OR=2.4; 95% CI: 1.42-4.10). Determinants of weight deficit at the basic, underlying and immediate levels were: per capita monthly income of less than one-fourth of the minimum wage (OR=3.4; 95% CI: 1.41-8.16), not attending prenatal visits (OR=2.1; 95% CI: 1.03-4.35) and low birth weight (OR=4.8; 95% CI: 2.00-11.48) respectively.
CONCLUSIONS:Children's weight and linear deficits were accounted for the overlapping of poor material living conditions, limited access to health care and disease burden. Interventions aimed at improving living conditions and better access to health care programs are strategies towards equity in children's health and nutrition.
