AB - Background: COVID-19 public health and social measures (PHSM) may have affected children’s development, for example by reducing their interaction with others. We examined associations between PHSM and developmental concerns among young children in Scotland. Methods: We utilised data from routine 13-15 month and 27-30 month child health reviews, covering all children in Scotland who took part in reviews between January 2019 and August 2023 and had full developmental data. Interrupted time-series analysis assessed slope changes in the weekly proportion of children with health visitor-identified developmental concerns following the March 2020 introduction of, and August 2021 removal of, PHSM. Outcomes were any 13-15 month and 27-30 month developmental concerns, and domain-specific concerns regarding speech-language-communication, problem solving, gross motor, personal-social, emotional-behavioural and fine motor development. Findings: Weekly proportions were based on 257,532 children, covering 13-15 month review records for 186,265 children (95,506 [51.3%] male and 90,756 [48.7%] female) and 27-30 month review records for 186,766 children (95,209 [51.0%] male and 91,557 [49.0%] female). The March 2020 PHSM introduction was associated with a slope change increase in the proportion of children with any developmental concerns (+0.091 percentage points per week [95% CI: 0.065, 0.116] at 13-15 months and +0.076 percentage points per week [95% CI: 0.048, 0.104] at 27-30 months. The August 2021 PHSM removal was associated with a slope change decrease in the proportion of children with any developmental concerns at 27-30 months (-0.067 percentage points per week [95% CI: -0.088, -0.046]), but not 13-15 months, in the main analysis. Results were broadly consistent across developmental domains. Interpretation: COVID-19 PHSM were associated with increased developmental concerns among young children in Scotland. While leveraging interrupted time-series analysis yields findings consistent with a causal impact of PHSM, the influence of potential time-varying confounders cannot be ruled out.
