Abstract

Background: Previous studies have shown that physical activity interventions positively affect core symptoms and executive functioning in children with attention-deficit/hyperactivity disorder (ADHD). However, comparisons between different physical activity interventions still need to be made. This study is the first to analyze the effects of 10 different types of physical activity on children with ADHD through a network meta-analysis.

Methods: PubMed, Embase, Web of Science, and Cochrane Library databases were searched for randomized controlled trials on the effects of physical activity interventions on children with ADHD. The search time frame was from database creation to October 2022. Two investigators independently performed literature screening, extraction, and quality assessment. Network meta-analysis was performed with Stata 15.1.

Results: A total of 31 studies were included, and the results indicated that perceptual-motor training was the most effective in terms of motor ability and working memory (SUCRA = 82.7 and 73.3%, respectively). For attention problems and cognitive flexibility, aquatic exercise was the most effective (SUCRA = 80.9 and 86.6%, respectively). For social problems, horsemanship was the most effective (SUCRA = 79.4%). For inhibition switching, cognitive-motor training was the most effective (SUCRA = 83.5%).

Conclusion: Our study revealed that aquatic exercise and perceptual-motor training had a superior overall performance. However, the effects of various physical activity interventions on different indicators in children with ADHD can vary depending on the individual and the intervention’s validity. To ensure an appropriate physical activity intervention is selected, it is important to assess the severity of symptoms exhibited by children with ADHD beforehand.

> This is driven almost entirely by a large increase in violent crime and suicides during the pandemic

Suicides decreased during the pandemic.

From the article:
> "The number of people injured by gunfire was nearly 40% higher in 2020 and 2021, compared with 2019, the Centers for Disease Control and Prevention said in a study published Thursday. In 2022, gun injuries tapered off, but were still 20% higher than before the pandemic."

By contrast, suicides were lower in 2020 than 2019, and only modestly higher in 2021 (to 2018 levels).

Check out the data table for yourself; the changes in firearm injury rate don't look at all similar to the changes in suicide rate.
