Cognitive development in babies with exclusive breastfeeding using Mullen Scale test
Abstract
Background Breast milk is the best nutrition for babies' growthand development. There are many reasons for discontinuation of
exclusive breastfeeding (BF).
Objective To evaluate the impact of exclusive breastfeeding on
babies' cognitive development.
Methods A cohort study was conducted for full term newborn
babies. They were evaluated for cognitive development using
Mullen scale test at of 6 and 9 months; t test was used to obtain
mean difference of cognitive values. Logistic regression analysis
was performed to distinguish factors associated with the cognitive
development.
Results One hundred and forty babies were enrolled to this study
(70 babies with exclusive BF and 70 babies with non-exclusive
BF). There were 34 boys (49%) in exclusive and 37 boys (53%) in
non-exclusive BF group. Mean cognitive score at age six months
was 1.41 points higher for exclusive BF group, mean rate 174.31
(SO 4.89) and 172.90 (SO 4.19) for exclusive and non-exclusive BF,
respectively. Mean cognitive score at nine months was 1.49 point
higher in exclusive BF group with mean rate 175.28 (SO 4.39) and
173.82 (SO 3.80) for exclusive and non-exclusive BF respectively.
Logistic regression analysis showed that exclusively breastfed babies
had higher mean Mullen cognitive score of 4. 761 (95% CI 1.341;
16.907) and 4.431 (95% CI 1.313; 14.949) times at sixth and ninth
month respectively than non-exclusive BE
Conclusion Exclusively breastfed babies may have higher mean
score of Mullen cognitive score at sixth and ninth months when
compared with those who are non exclusively breastfed.
