Prenatal and postnatal lipid-based nutrient supplementation and cognitive, social-emotional, and motor function in preschool-aged children in Ghana: a follow-up of a randomized controlled trial.

ABSTRACT: Background:Adequate nutrition is necessary for brain development during pregnancy and infancy. Few randomized controlled trials of supplementation during these periods have measured later developmental outcomes. Objective:Our objective was to investigate the effects of provision of prenatal and postnatal lipid-based nutrient supplements (LNS) on child development at preschool age. Methods:We conducted a follow-up study of 966 children aged 4-6 y in 2016, born to women who participated in the International Lipid-Based Nutrient Supplements-DYAD trial conducted in Ghana in 2009-2014, representing 79% of eligible children. Women ?20 weeks of gestation were randomized to daily LNS or multiple micronutrient (MMN) capsules during pregnancy through 6 mo postpartum or iron and folic acid (IFA) capsules during pregnancy and calcium placebo capsules during 6 mo postpartum. Children in the LNS group received LNS from 6 to 18 mo. Primary outcomes of this follow-up study were (1) a cognitive factor score based on a test battery adapted from several standard tests, 2) fine motor score (9-hole pegboard test), and (3) social-emotional difficulties (Strengths and Difficulties Questionnaire; SDQ). Eight secondary outcomes were calculated in specific domains (e.g., language, SDQ prosocial). Analysis was by a complete case intention to treat in a 2-group comparison: LNS compared with non-LNS (MMN + IFA). Results:Children in the LNS group had significantly lower social-emotional difficulties z-scores than children in the non-LNS group (adjusted for child age ? = -0.12, 95% CI: -0.25, 0.02, P = 0.087; fully adjusted ? = -0.16, 95% CI: -0.29, -0.03, P = 0.013). The effect of LNS on social-emotional difficulties score was larger among children living in households with lower home environment scores (P-interaction = 0.081). No other outcomes differed between the 2 intervention groups. Conclusions:Provision of LNS during the first 1000 d of development improved behavioral function, particularly for children from low nurturing and stimulation households, but did not affect cognition at preschool age in this setting.

Project description:BackgroundProvision of small-quantity lipid-based nutrient supplements (SQ-LNSs) during early life improves growth and development. In the International Lipid-Based Nutrient Supplements DYAD-Ghana trial, prenatal and postnatal SQ-LNS reduced social-emotional difficulties at age 5 y, with greater effects among children in less-enriched home environments.ObjectivesWe aimed to investigate the effect of prenatal and postnatal SQ-LNS on children's social-emotional problems at age 9-11 y.MethodsIn 2009-2011, 1320 pregnant women ≤20 wk gestation were randomly assigned to receive the following daily until 6 mo postpartum: 1) iron and folic acid until delivery, then placebo, 2) multiple micronutrients (MMNs), or 3) SQ-LNS (20 g/d). Children in group 3 received SQ-LNS from 6 to 18 mo. In 2021, we evaluated children's social-emotional outcomes with 6 assessment tools that used caregiver, teacher, and/or self-report to measure socioemotional difficulties, conduct problems, temperament, mood, anxiety, and emotion management.ResultsWe assessed outcomes in 966 children, comprising 79.4% of 1217 participants eligible for re-enrolment. No significant differences were found between the SQ-LNS and control (non-LNS groups combined) groups. Few children (<2%) experienced high parent-reported social-emotional difficulties at 9-11 y, in contrast to the high prevalence at age 5 in this cohort (25%). Among children in less-enriched early childhood home environments, the SQ-LNS group had 0.37 SD (-0.04 to 0.82) lower self-reported conduct problems than the control group (P-interaction = 0.047).ConclusionsOverall positive effects of SQ-LNS on social-emotional development previously found at age 5 y are not sustained to age 9-11 y; however, there is some evidence of positive effects among children in less-enriched environments. The lack of effects may be owing to low prevalence of social-emotional problems at preadolescence, resulting in little potential to benefit from early nutritional intervention at this age in this outcome domain. Follow-up during adolescence, when social-emotional problems more typically onset, may yield further insights.

Project description:BackgroundRecent studies have suggested an association between prenatal paracetamol exposure and adverse neurodevelopmental outcomes in children. However, these findings may be confounded by unmeasured factors related to maternal use of paracetamol and child outcomes.ObjectiveTo examine the association between duration and timing of prenatal paracetamol exposure on parent-reported communication skills, behaviour, and temperament in preschool-aged children, with focus on the role of unmeasured confounding.MethodsWe used data from the Norwegian Mother and Child Cohort Study. Linear and generalised linear models with inverse probability weights and robust standard errors were used to quantify the association between prenatal paracetamol exposure and continuous and categorical outcomes.ResultsOf the 32 934 children included in our study, 8374 (25.4%), 4961 (15.1%), and 1791 (5.4%) were prenatally exposed to paracetamol in one, two, and three trimesters, respectively. Children exposed to paracetamol in two trimesters scored lower on shyness compared with unexposed children (β -0.62, 95% confidence interval [CI] -1.05, -0.19). Children exposed to paracetamol in three trimesters had a moderate increased risk of internalising behaviour problems (relative risk (RR) 1.36, 95% CI 1.02, 1.80) and borderline externalising behaviour problems (RR 1.22, 95% CI 0.93, 1.60) compared with unexposed children. Children exposed to paracetamol in 2nd/3rd trimester scored lower on shyness (β -0.32, 95% CI -0.66, 0.02) compared with unexposed children. Sensitivity analyses indicated that unmeasured confounders play an important role and may potentially bias the effect estimates away from the null.ConclusionsTiming of exposure and short-term use of paracetamol during pregnancy do not seem to pose any substantial risk of the outcomes examined. Although we found an association between paracetamol use in multiple trimesters and lower shyness and greater internalising behaviour in preschool-aged children, we cannot rule out chance or unmeasured confounding as possible explanations for these findings.

Project description:Background: Children and youth are facing three major challenges: (1) poor mental health, (2) physical inactivity, and (3) lack of school readiness. Fundamental movement skills (FMS) and social-emotional learning (SEL) are two developmental domains that are associated with each of these challenges. Currently, there is little focus on interventions that target both FMS and SEL. Thus, the purposes of this study were to: (1) examine the acceptability and feasibility of an FMS and SEL program (Move 2 Smile) and (2) assess the impact of Move 2 Smile on FMS and SEL in children. Methods: An exploratory, pilot study using a within-subjects design was conducted. Descriptive statistics were computed to assess the acceptability and feasibility of the Move 2 Smile program. Changes in FMS and SEL were analyzed using a paired sample t-test. A focus group was conducted with parents to gain feedback after the program ended. Results: Eleven children (four girls; M age = 50.56 months, SD = 8.63) participated, with families attending 80% of the sessions. The children and parents rated the enjoyment of the program 4.1/5 and 4.7/5, respectively. The instructor rated the children's perceived enjoyment 4.6/5 and feasibility of the sessions 4.7/5. Parents engaged in the FMS take-home activities once per week and the SEL activities three times per week. The intervention had a non-significant small to medium effect on FMS (d z = 0.42, p = 0.19), a significant large effect on social skills (d z = 1.38, p = 0.001) and emotion expressiveness (d z = 0.79, p = 0.03), and a non-significant small to medium effect on emotion knowledge (d z = 0.58, p = 0.10) and emotion regulation (d z = 0.44, p = 0.17). The results from the focus group suggest that parents and children enjoyed the program and that the program was useful and effective at impacting FMS and SEL. Conclusions: This intervention is one of the first to intentionally target both FMS and SEL. Children, parents, and instructors deemed this program as acceptable and feasible. These preliminary findings warrant future evaluations of Move 2 Smile, including a randomized controlled trial.
