Insights
Exclusive breastfeeding protects Tanzanian infants from diarrhoea. Introducing complementary foods before 6 months increases diarrhoea risk. Strengthening infant and young child feeding programs is crucial.
Area of Science:
- Public Health
- Pediatrics
- Nutrition
Background:
- Diarrhoea is a major cause of child mortality in Tanzania.
- Optimal infant and young child feeding (IYCF) practices are linked to reduced diarrhoea, but evidence for strategic interventions in Tanzania is limited.
Purpose of the Study:
- To examine the association between infant and young child feeding (IYCF) practices and diarrhoea in Tanzanian children under 24 months.
- To provide evidence for targeted interventions to reduce childhood diarrhoea in Tanzania.
Main Methods:
- Utilized Tanzania Demographic and Health Survey data.
- Employed multivariable logistic regression analysis, adjusting for confounding factors and cluster variability.
- Estimated diarrhoea prevalence stratified by IYCF practices.
Main Results:
- Exclusive breastfeeding (EBF) and predominant breastfeeding (PBF) were associated with lower diarrhoea prevalence in infants aged 0-5 months.
- Introduction of complementary foods at 6-8 months was linked to a higher prevalence of diarrhoea compared to EBF.
- EBF and PBF showed a protective effect against diarrhoea (AOR 0.31 and 0.30, respectively), while early complementary feeding increased risk (AOR 2.91).
Conclusions:
- EBF and PBF are protective against diarrhoeal illness in Tanzanian children.
- Early introduction of complementary foods is associated with increased diarrhoea risk.
- Strengthening IYCF programs can improve feeding behaviors and reduce the burden of diarrhoea in children under two years.
Background:
Diarrhoea is a leading cause of child mortality in Tanzania. The association between optimal infant feeding practices and diarrhoea has been reported elsewhere, but the evidence has been limited to promote and advocate for strategic interventions in Tanzania. This study examined the association between infant and young child feeding (IYCF) practices and diarrhoea in Tanzanian children under 24 months.
Methods:
The study used the Tanzania Demographic and Health Survey data to estimate the prevalence of diarrhoea stratified by IYCF practices. Using multivariable logistic regression modelling that adjusted for confounding factors and cluster variability, the association between IYCF practices and diarrhoea among Tanzanian children was investigated.
Results:
Diarrhoea prevalence was lower in infants aged 0-5 months whose mothers engaged in exclusive breastfeeding (EBF) and predominant breastfeeding (PBF) compared to those who were not exclusively and predominantly breastfed. Infants aged 6-8 months who were introduced to complementary foods had a higher prevalence of diarrhoea compared to those who received no complementary foods, that is, infants who were exclusively breastfed at 6-8 months. Infants who were exclusively and predominantly breastfed were less likely to experience diarrhoea compared to those who were not exclusively and predominantly breastfed [adjusted odds ratio (AOR) 0.31, 95% confidence interval (CI) 0.16-0.59, P < 0.001 for EBF and AOR = 0.30, 95% CI 0.10-0.89, P = 0.031 for PBF]. In contrast, infants aged 6-8 months who were introduced to complementary foods were more likely to experience diarrhoea compared to those who received no complementary foods (AOR = 2.91, 95% CI 1.99-4.27, P < 0.001).
Conclusions:
The study suggests that EBF and PBF were protective against diarrhoeal illness in Tanzanian children, while the introduction of complementary foods was associated with the onset of diarrhoea. Strengthening IYCF (facility- and community-based) programmes would help to improve feeding behaviours of Tanzanian women and reduce diarrhoea burden in children under 2 years.
