Correlates of Fundamental Motor Skills in the Early Years (0–4 Years): A Systematic Review

Aim : This systematic review aims to summarize evidence on correlates of fundamental motor skills in typically developing children aged 0–4 years. Methods : A literature search (PubMed, Embase, PsycINFO, and SPORTDiscus) was performed from 2000 till 23 May 2022. Inclusion criteria was cross-sectional and prospective studies examining associations between a potential correlate and fundamental motor skills in typically developing, apparently healthy children aged 0–4 years. Two independent reviewers performed screening and methodological quality assessment. Results : Eighty-three studies met eligibility criteria and were included. Thirteen studies were of high methodological quality. In children aged <1 year, we found no evidence for family income, breastfeeding-related, sleep-related, home environment, and socioeconomic variables. In children aged 1–2 years, we found no evidence for sex, growth-related variables, singleton birth, and family income. In children aged 2–4 years, we found no evidence for screen behavior, toxicity, parental education, family income, socioeconomic variables, and maternal depression/anxiety and moderate evidence for a positive association with early childhood education and care setting type. For other examined correlates, we found insufficient evidence (inconsistent findings or only one study available). Conclusions : We found insufficient evidence for over half of examined potential correlates of fundamental motor skills. We recommend investing in better research methodologies and improved reporting.
