Delays in children's preventive health services during the COVID-19 pandemic.

Published: May 2022   Journal: Family Medicine

Stay-at-home orders, social isolation recommendations, and fear of COVID-19 exposure have led to delays in children’s preventive health services during the pandemic. Delays can lead to missed opportunities for early screening and detection of health problems, and increased risks for outbreaks of vaccine-preventable diseases. Understanding prevalence of and reasons for missed, delayed, or skipped preventive health services is important for developing strategies to achieve rapid catch-up of essential health services. Using the Household Pulse Survey (n=37,064), a large, nationally-representative household survey fielded from April 14 to May 10, 2021, we examined prevalence of households with children who have missed, delayed, or skipped preventive health services, and factors associated with and reasons contributing to missed, delayed, or skipped preventive health services.

Published: May 2022

The COVID-19 pandemic‒related BMI gain and obesity prevalence changes in children have not been clearly elucidated, especially in China. This study aims to assess the impact of pandemic-related BMI and obesity prevalence change in Chinese children aged 8–12 years. On the basis of the Health Promotion Program for Children and Adolescents in Suzhou of China, a total of 72,175 children aged 8–12 years with complete data during 2017–2020 were included. Yearly BMI z-score changes and age- and sex-adjusted BMI changes before (2017–2019) and during (2019–2020) the pandemic were calculated. Multivariate mixed linear models were used to examine the possible difference in annual BMI change rate before and during the pandemic among subgroups.

Published: December 2021   Journal: Public Health Reports

The COVID-19 pandemic led to a substantial drop in US children's preventive care, which had not fully rebounded by the end of 2020. We sought to estimate the overall prevalence of missed, skipped, or delayed preventive checkups among households with children in the last 12 months because of the pandemic. We used data from the US Census Bureau's Household Pulse Survey, Phase 3.1 (collected April-May 2021). The analytic sample included 48 824 households with ≥1 child or adolescent aged <18 years. We estimated both national and state-level prevalences, examined associations with sociodemographic and household characteristics, and described reasons for missed or delayed preventive visits.

COVID-19 & Children: Rapid Research Response

UNICEF Innocenti is mobilizing a rapid research response in line with UNICEF’s global response to the COVID-19 crisis. The initiatives we’ve begun will provide the broad range of evidence needed to inform our work to scale up rapid assessment, develop urgent mitigating strategies in programming and advocacy, and preparation of interventions to respond to the medium and longer-term consequences of the COVID-19 crisis. The research projects cover a rapid review of evidence, education analysis, and social and economic policies.
