Background

Studies on breastfeeding promotion and support interventions suggest some economic benefits. This study assessed the direct and indirect costs of a multicomponent breastfeeding promotion and support intervention during the first two years of the infant’s life.

Methods

This is a cost-benefit analysis of data generated from a randomized controlled trial that investigated whether provision of a multicomponent breastfeeding promotion and support intervention to Lebanese mothers in the first six months postpartum would improve breastfeeding rates compared to standard obstetric and pediatric care. Data of 339 participants on sociodemographics, mother and infant health, infant nutrition, direct and indirect costs of the intervention were used to assess the benefit-cost ratio (BCR) of the intervention at one, six, 12, and 24 months as primary outcome. Secondary outcomes included overall costs of infant nutrition and infant-mother dyad health costs during the first two years. Multiple linear regression models explored the effect of the intervention on the overall infant nutrition cost and mother-infant health costs. Similar regression models investigated the association between cost variables and infant nutrition types (exclusive breastfeeding, mixed feeding, artificial milk). Intention to treat analyses were conducted using SPSS (version 24). Statistical significance was set at ap-value below 0.05.

Results

The prevalence ofExclusive/Predominantbreastfeeding among participants declined from 51.6% in the first month to 6.6% at the end of second year. The multicomponent breastfeeding intervention incurred 485 USD more in costs than the control group during the first six months but was cost-efficient at one year (incremental net benefits of 374 USD; BCR = 2.44), and two years (incremental net benefits of 472 USD; BCR = 2.82). In adjusted analyses, the intervention was significantly associated with fewer infant illness visits in the first year (p= 0.045). Stratified analyses by the infant nutrition type revealed that infants who were onExclusive/Predominant, orAny Breastfeedinghad significantly more favorable health outcomes at different time points during the first two years (p<0.05) compared to infants receivingArtificial Milkonly, with health benefits being highest in theExclusive/Predominantbreastfeeding group. Moreover,Exclusive/PredominantandAny Breastfeedinghad significantly lower costs of infant illness visits, hospitalizations, and infant medications during the two years (p<0.05) but had additional cost for maternal non-routine doctor visits due to breastfeeding (allpvalues <0.05). Whereas the overall cost (direct and indirect) during the first six months was significantly lower for theExclusive/Predominantbreastfeeding infants (p= 0.001), they were similar in infants onMixed FeedingorArtificial Milk.

Conclusions

Breastfeeding is associated with significant economic and infant health benefits in the first two years. In the context of the current economic crisis in Lebanon, this study provides further evidence to policymakers on the need to invest in national breastfeeding promotion and support interventions.
