Background: Exclusive breastfeeding (EBF) for six months bestows many benefits to the
infant and the mother and is recommended by the WHO. Many infants in Kenya are
introduced to mixed feeding earlier than recommended resulting in a low duration of EBF.
Broad objective: To assess the duration of exclusive breastfeeding and investigate the
factors influencing the duration of EBF amongst mothers with infants between six and nine
months of age in Nairobi.
Methods: A cross-sectional study design was used. Three health facilities in Nairobi
County were sampled. A total of 194 mothers with children six to nine months of age were
interviewed using an interviewer administered questionnaire with closed and open ended
questions. Data analysis was done using the Statistical Package for Social Sciences software
(SPSS) version 21. Descriptive statistics were generated, Chi-square test and Fisher’s exact
test was done for relationships of variables. Logistic regression was done to establish the
relationship between EBF and various explanatory variables. P value set at < 0.05 was
used to interpret the significance of the statistical tests.
Results: The mean age of the mothers was 27.2 ±5.2 (95% CI 26.450-28.000). Most
mothers (82.5%) were married, while 15.5% had never been married. A majority (79.3%)
had attained secondary school and above level of education. The median duration of
reported EBF based on continuous breastfeeding since birth to six months, was found to be
six months. The prevalence of continuous exclusive breastfeeding since birth to six months
was 68.0% (95% CI; 60.800-74.700). In bivariate Chi-square and Fisher’s exact test analysis,
maternal knowledge that breast milk alone can sustain the baby for six months (P-value
=0.001), breastfeeding problems which had interfered with breastfeeding (P=0.006) and
confidence that breast milk alone would be adequate for six months (P=0.007) had significant
associations with EBF duration. In multivariate logistic regression analysis, breastfeeding
problems which interfered with breastfeeding (OR: 0.151, 95% CI: 0.042-0.542, P=0.004)
and confidence that breast milk alone without even water can sustain the baby for six
months (OR: 4.885, 95% CI: 1.592-14.985, P=0.006) were significantly associated with
EBF duration. After controlling for pre-lacteal feeding, maternal breastfeeding problems
that interfered with breastfeeding (AOR: 0.166, P=0.012), and maternal confidence that
breast milk alone can sustain the baby for six months (AOR: 17.641, P=0.018) were
retained as predictors for a longer EBF duration.
Conclusion: The median duration of EBF in this study was found to be six months. The
factors that influenced the duration of EBF were maternal knowledge that breast milk
alone was adequate for the infant for six months, maternal confidence that breast milk
alone without even water can sustain the baby for six months and maternal breast problems
that influenced breastfeeding.
Recommendations: There is need by health workers in the study area to scale up
education of mothers to ensure they fully understand all the EBF practices, it’s adequacy
for the infant for six months and all the benefits to continue improving maternal
confidence in breast milk and breastfeeding promotion information offered by the Ministry
of Health to mothers should include more visual aids and demonstrations for mothers on
how to cope with breast complications to reduce their interfering with breast feeding. |
