Normative cognition and the effects of a probiotic food intervention in first grade children in Côte d’Ivoire
Scientific reports(2022)
摘要
The cognitive skills critical for success have largely been studied in Western populations, despite the fact that children in low- and middle-income countries are at risk to not reach their full developmental potential. Moreover, scientists should leverage recent discovery to explore means of boosting cognition in at-risk populations. This semi-randomized controlled trial examined normative cognitive development and whether it could be enhanced by consumption of a probiotic food in a sample of 251 4- to 7-year-old children in urban schools in Côte d’Ivoire. Participants completed executive functioning measures at baseline (T1) and 5 months later (T2). After T1, children in one school received a probiotic ( N = 74) or placebo ( N = 79) fermented dairy food every day they were in school for one semester; children in the other school ( N = 98) continued their diet as usual. Children improved on all tests across time (Cohen’s d = 0.08–0.30). The effects of probiotic ingestion were inconclusive and are interpreted with caution due to socio-political factors affecting daily administration. Given the general feasibility of the study, we hope that it will serve as an inspiration for future research into child development and sustainable (health-promoting) interventions for school children in developing nations.
