Insights
Exclusive breastfeeding prevalence was high initially but declined over six months in a Brazilian cohort. The Well Baby Program showed adequacy but requires further efforts to extend exclusive breastfeeding duration.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Context:
- Study conducted in Pelotas, Brazil, focusing on low-income families.
- Utilized a historical cohort of children born between 2000-2002.
- Primary health care facility setting analyzed for breastfeeding practices.
Purpose:
- To assess the prevalence and duration of exclusive breastfeeding.
- To evaluate the effectiveness of the Well Baby Program in promoting breastfeeding.
- To identify trends in exclusive breastfeeding interruption post-birth.
Summary:
- Exclusive breastfeeding prevalence was 95.0% in the first month, decreasing to 35.0% by six months.
- Median duration of exclusive breastfeeding was four months.
- Prevalence and median duration exceeded Brazilian national rates, indicating program effectiveness.
Impact:
- The Well Baby Program demonstrates success in promoting breastfeeding initiation and early duration.
- Further interventions are needed to increase exclusive breastfeeding rates until the recommended six months.
- Findings provide insights for public health strategies to improve infant nutrition in similar settings.
Abstract:
A historical cohort of children born between January 2000 and December 2002 from low-income families attending a primary health care facility on the periphery of Pelotas, Rio Grande do Sul, Brazil, was studied in relation to prevalence of exclusive breastfeeding. Analysis was based on a life table focusing on interruption of exclusive breastfeeding (month-by-month after birth) as the target outcome. Among the 112 children followed up from birth by the Well Baby Program, prevalence of exclusive breastfeeding in the first month of life was 95.0%, declining progressively to 81.0%, 64.0%, 53.0%, 39.0%, and 35.0%, respectively, from the second to the sixth month after birth. Median duration of exclusive breastfeeding was four months. Median duration of exclusive breastfeeding and prevalence among six-month-old infants were both higher than the Brazilian national rates and indicate the Program's adequacy in promoting breastfeeding. However, more effort should be made to increase the prevalence of exclusive breastfeeding until the sixth month of life.
