Insights
Exclusive breastfeeding duration in infants remained stagnant around 30 days, despite a significant increase in total breastfeeding duration over time. Key factors influencing this trend include maternal education and infant gender.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Exclusive breastfeeding is crucial for infant health and development.
- Understanding trends in breastfeeding duration is vital for public health interventions.
- Previous studies indicate varying durations of breastfeeding globally.
Purpose of the Study:
- To analyze temporal trends in the duration of exclusive breastfeeding.
- To identify associated protective factors influencing breastfeeding duration.
- To assess changes in breastfeeding practices over time.
Main Methods:
- Analysis of population survey data from 1991, 1997, and 2006.
- Inclusion of data from 935, 2081, and 1568 four-month-old infants, respectively.
- Poisson regression used to analyze prevalences concerning environmental, socioeconomic, maternal, and infant factors.
Main Results:
- Median total breastfeeding duration increased significantly from 89 days (1991) to 183 days (2006).
- Median exclusive breastfeeding duration remained stable at approximately 30 days between 1997 and 2006.
- Maternal schooling, maternal age, infant's address, and infant's gender were significant factors in the final model.
Conclusions:
- While total breastfeeding duration has improved, exclusive breastfeeding duration has not shown similar progress.
- Maternal education and infant's gender are identified as key factors associated with breastfeeding duration.
- Further research and targeted interventions are needed to promote longer exclusive breastfeeding periods.
Objective:
To analyze time trends in the duration of exclusive breastfeeding and associated protection factors.
Methods:
Prevalances for total breastfeeding and exclusive breastfeeding in a population of four-month-old infants were analyzed. Data were obtained from population surveys carried out in 1991, 1997, and 2006, with 935, 2081, and 1568 infants respectively. The data were retrieved from interviews answered by parents or guardians. The prevalences were analyzed by Poisson regression in regard to: environmental, behavioral and socioeconomic conditions, maternal variables, and biological factors of infant.
Results:
The median duration of total breastfeeding rose from 89 days (1991) to 106 days (1997), and finally to 183 days (2006). The median duration of exclusive breastfeeding remained around 30 days between 1997 and 2006. In the multivariate analysis, from the ten variables studied, only maternal schooling and age, address, and female gender of infant were maintained in the final explanatory model.
Conclusions:
Despite the significant increase in terms of total breastfeeding duration, the same did not occur with the duration of exclusive breastfeeding.
