Henrick et al. discovered that exclusively breastfed infants who were supplemented with Bifidobacterium longum subsp. infantis had significantly less enteric inflammation than control infants. See the article on page 749.
The authors take a longitudinal and intergenerational approach to studying infants born at extremely early gestational age, highlighting the extent to which a high-risk pregnancy is experienced by both mother and infant, with potentially lasting effects on the physical – and mental – health of the dyad. They focus their study on what they call positive child health outcomes at 10 years of age, measured using an index of chronic health problems. Yet concepts of positive health include attributes beyond the absence of disease, such as participation, resilience, and happiness. To study positive health outcomes – an endeavor that has much merit in light of the developmental plasticity children possess – we should use measures that explicitly and more fully encompass the many facets of well-being. Otherwise, we risk simply rebranding negative disease as positive health by providing it a new name.
