ABSTRACT
OBJECTIVE: To identify the prevalence of iron-deficiency anemia and associated factors in women at reproductive age in the city of Vitoria de Santo Antão, Pernambuco. METHODS: Cross-sectional study with a representative sample of 322 women aged between 15 and 49 years. Anemia was diagnosed by measuring hemoglobin below 12 g/dL. The independent variables were: demographic and socioeconomic conditions (age, race/color, education, literacy, presence of children aged < 5 years in the household, regime of residence occupation, ownership of assets, and per capita income), housing conditions (number of people in the household, number of bedrooms, and basic sanitation), food and nutrition security and women's health conditions (menarche, number of pregnancies, history of miscarriages, body mass index, and ferritin). Poisson regression was used to analyze the factors associated with anemia. RESULTS: The mean age of women surveyed was 31.1 ± 6.61 years old (standard deviation - SD) and the prevalence of anemia was 18.6% (95%CI 14.7 - 23.3). After multivariate analysis, anemia was significantly associated with age ≤ 19 years and low ferritin. CONCLUSION: The prevalence of anemia is characterized as a mild public health problem and follows the world trend in developing countries.

RESUMO: Objetivo: Determinar a prevalência de anemia e seus fatores associados em mulheres em idade reprodutiva do município de Vitória de Santo Antão, Pernambuco. Métodos: Estudo transversal com amostra representativa de 322 mulheres, com idade entre 15 e 49 anos. A anemia foi diagnosticada pela dosagem de hemoglobina abaixo de 12 g/dL. As variáveis independentes foram: condições demográficas e socioeconômicas (idade, raça/cor, escolaridade, alfabetização, presença de crianças com idade < 5 anos no domicílio, regime de ocupação de residência, posse de bens e renda familiar per capita), condições de moradia (número de pessoas no domicílio, número de dormitórios e condições de saneamento básico), segurança alimentar e nutricional e condições de saúde das mulheres (menarca, número de gestações, passado de abortos, índice de massa corporal e ferritina). A regressão de Poisson foi utilizada para a análise dos fatores associados à anemia. Resultados: A média de idade das mulheres investigadas foi de 31,1 ± 6,61 anos (desvio padrão - DP) e a prevalência de anemia, de 18,6% (IC95% 14,7 - 23,3). Após análise multivariável, a anemia apresentou associação significativa com idade ≤ 19 anos e com baixo índice de ferritina. Conclusão: A prevalência de anemia encontrada se caracteriza como um problema de saúde pública de grau leve e segue a tendência mundial de países em desenvolvimento.
