Abstract
Analisou-se a prevalência e os fatores associados à deficiência de vitamina A (DVA) em mães (664) e seus filhos (790) menores de cinco anos em Pernambuco/2006. Estudo transversal populacional, com amostra representativa do meio urbano e rural. A DVA foi definida como níveis de retinol sérico < 20µg/dL para os dois grupos (mães e filhos). Análises bi e multivariadas foram realizadas utilizando o modelo log-log complementar como função de ligação adotando-se modelo de ordenação hierárquica explicativa da DVA para as crianças e modelo logístico para as mães. A prevalência de DVA foi 6,9% nas mães e 16,1% em seus filhos, com ocorrências semelhantes para cada grupo na comparação urbano x rural. Na área urbana, o regime de ocupação da moradia teve relação significante com a DVA nas mães. Para crianças urbanas, após o ajuste final do modelo, figuraram como variáveis preditivas a idade da mãe; nº de consultas pré-natais e peso ao nascer. No meio rural a DVA materna se associou à DVA dos filhos RP = 3,99 (IC:1,73-9,19), ao peso ao nascer e diarreia nos últimos 15 dias. A DVA mantém-se como um problema de saúde pública em Pernambuco, com marcantes diferenças de prevalência e fatores associados em mães e filhos.
The prevalence and risk factors associated with vitamin A deficiency (VAD) were analyzed in 664 mothers and their 790 children under the age of five in Pernambuco in 2006. A population-based cross-sectional study, with a representative sample in urban and rural areas was conducted. VAD was defined as serum retinol levels < 20 mg/dL for both groups (mothers and children). Bi and multivariate analysis were performed using the complementary log-log model as a link function adopting a model of explanatory hierarchical order of VAD to children and a logistic model for mothers. The prevalence of VAD was 6.9% in mothers and 16.1% in their children, with similar statistics for urban and. rural groups. In the urban area, the housing occupation regime had a significant association with VAD in mothers. After the final adjustment of the model for urban children, the mother's age, the number of pre-natal consultations and birth weight were featured as predictive variables. In rural areas, VAD in mothers is associated with VAD in children; PR= 3.99 (95% CI:1.73-9.19), with their birth weight and the incidence of diarrhea in the previous 15 days. VAD continues to be a public health issue in the state of Pernambuco, with marked variations in prevalence and associated factors in mothers and children.
