Fatores associados com a duração do aleitamento materno

Abstract

Objectives: To determine rates of exclusive breastfeeding and of complementary feeding and to identify variables that interfere with breastfeeding in the municipality of Itaúna, MG, Brazil.Methods: A longitudinal study was undertaken enrolling 246 women who gave birth at the maternity unit of the Manoel Gonçalves Hospital, in Itaúna, MG. The mothers and their infants were seen monthly for the first 12 months after birth or until they stopped breastfeeding. Survival analysis procedures were used to study the duration of exclusive breastfeeding and of complementary feeding. The impact on breastfeeding duration of a series of co-variables was assessed by means of Cox regression modeling. Results:The prevalence of exclusive breastfeeding at 6 months was 5.3%, and for breastfeeding at 12 months it was 33.7%. The median duration of exclusive breastfeeding was 40 days, and median breastfeeding duration was 237 days. Multivariate analysis demonstrated a negative association (p < 0.05) between duration of exclusive breastfeeding and the following variables: intended breastfeeding duration (< 12 months), birth weight of child (< 2,500 g) and use of a pacifier. Shorter breastfeeding duration was associated (p < 0.05) with maternal age (< 20 years), number of prenatal consultations (< 5 and > 9 consultations), use of alcohol or tobacco, delay before first feed (> 6 hours) and use of a pacifier. Conclusions

Prevalência de aleitamento materno e fatores associados no município de Londrina-PR

“…Other reflections are necessary about the use of artificial nipples, because they have been described in the literature as a factor that contributes to weaning and that, in the current study, presented a statistically significant association with weaning in all ages; a result that was also observed in other studies (15,27,28) .…”

“…Women younger than 20 years of age breastfed for a shorter time, possibly because mothers who are older have more knowledge and experience concerning breastfeeding (15) . This indicates the need to offer individualized care to adolescent mothers to support them regarding factors that may discourage breastfeeding.…”

Fatores associados à interrupção do aleitamento materno exclusivo de lactentes nascidos com baixo peso assistidos na atenção básica

“…Dos fatores relacionados às condições após a alta hospitalar investigados, mostraram associação com a interrupção do AME no terceiro mês a presença de queixa da mãe na amamentação no primeiro mês e o uso de chupeta, apresentados tanto no primeiro quanto no segundo mês de vida do recém-nascido, independentemente dos fatores antes mencionados. No que diz respeito à idade da mãe, ser jovem tem sido apontado como um dos fatores de risco à continuidade do AME 20,22 , o que é consistente com o resultado do presente estudo. Exame detalhado dos resultados (não mostrados em tabelas) das análises de regressão hierarquizada mostra que, mesmo após todos os ajustes realizados, a categoria mencionada manteve a magnitude e a significância estatística, indicando que, entre as mães mais jovens, a probabilidade de interromper o AME é maior, independentemente de todas as demais condições, comparando-se àquelas do grupo etário entre 18 e 34 anos.…”

Prevalence and associated factors for early interruption of exclusive breastfeeding: meta-analysis on Brazilian epidemiological studies

“…1,326 articles in the database were identified, in which 25 were selected for qualitative synthesis 2,10-33 and 22 were included in the meta-analysis. 2,[10][11][12][13][14][15][16][17][18][19][21][22][23]25,[27][28][29][30][31][32] The reasons for the exclusion of the articles were the absence of the association measurements, non-observational study designs, the EBF interruption assessment in groups of adolescent mothers and only breastfeeding analysis in the first month of life.…”
