Attention-deficit/hyperactivity disorder (ADHD) is a developmental and neurological disorder with no current cure that can cause many difficulties for adults and children [1]. For those with ADHD, they can experience trouble with self-control, paying attention and daily functioning [2]. Specifically for children, ADHD can cause challenges that also directly affect their families and their school experiences [1]. The effects of the COVID-19 pandemic on disorders such as ADHD are still being currently studied, and this project aims to analyze pre- and post-pandemic data to determine any associations with ADHD prevalence and other environmental factors in children’s homes and schools, as well as demographics, across a three-year time period. The data used for this analysis is from the annual National Survey of Children’s Health (NSCH) for years 2019 (n = 29,433), 2020 (n = 42,777) and 2021 (n = 50,892) [3,4]. The NSCH is an annual web and mail-based survey that provides a wealth of information on reported childhood mental and physical health, access to quality health care, and social, community and family background for children in the United States [3]. For the data analysis, original categorical variables from the NSCH datasets like age, sex, race, family income, food insufficiency, household tobacco use, childhood technology use and school safety were used as predictors for modeling. All study variables were associated with the outcome of interest and results were statistically significant. Odds ratios for predictors were summarized across all three years using multiple logistic regression and the results across three years were compared.
