Background: Since the beginning of the COVID-19 pandemic, a great number of papers have been published in the pediatric field. Objective: We aimed to assess research around the globe on COVID-19 in the pediatric field by bibliometric analysis, identifying publication trends and topic dissemination and showing the relevance of publishing authors, institutions, and countries. Methods: The Scopus database was comprehensively searched for all indexed documents published between January 1, 2020, and June 11, 2020, dealing with COVID-19 in the pediatric population (0-18 years). A machine learning bibliometric methodology was applied to evaluate the total number of papers and citations, journal and publication types, the top productive institutions and countries and their scientific collaboration, and core keywords. Results: A total of 2301 papers were retrieved, with an average of 4.8 citations per article. Of this, 1078 (46.9%) were research articles, 436 (18.9%) were reviews, 363 (15.8%) were letters, 186 (8.1%) were editorials, 7 (0.3%) were conference papers, and 231 (10%) were categorized as others. The studies were published in 969 differentjournals, headed by The Lancet. The retrieved papers were published by a total of 12,657 authors from 114 countries. The most productive countries were the United States, China, and Italy. The four main clusters of keywords were pathogenesis and clinical characteristics (keyword occurrences: n=2240), public health issues (n=352), mental health (n=82), and therapeutic aspects (n=70). Conclusions: In the pediatric field, a large number of articles were published within a limited period on COVID-19, testifying to the rush to spread new findings on the topic in a timely manner. The leading authors, countries, and institutions evidently belonged to the most impacted geographical areas. A focus on the pediatric population was often included in general articles, and pediatric research about COVID-19 mainly focused on the clinical features, public health issues, and psychological impact of the disease.

Background: Parents of adolescents with internet addiction are confronted with their children's internet problems on a daily basis. Parents may notice that adolescents with addiction may also have emotional and behavioral problems, including impulsivity and violence. Parenting styles have been found to be related to internet addiction. Objective: The purpose of this study is to investigate parents' perspectives on their parenting style, relationship with their child, and the degree of internet addiction and emotional and behavioral problems of their child. Methods: A web survey was conducted with 600 parents of children between the ages of 12 and 17 years, from October 14 to 18, 2021, across Japan. Respondents were recruited by an internet research company and were asked to complete an anonymous online questionnaire. The survey was divided into two groups: 300 parents who answered "yes" to the question "Do you think your child is dependent on the internet?" and 300 parents who answered "no" to that question. Questionnaires were collected until each group had 300 participants. The questionnaire included (1) the Parent-Child Internet Addiction Test (PCIAT), (2) the daily time spent using the internet, (3) the Strengths and Difficulties Questionnaire (SDQ), (4) the Parenting Style and Dimensions Questionnaire (PSDQ), and (5) the Relationship Questionnaire (RQ) measuring self-report attachment style prototypes. Results: Mean scores of the PCIAT and the daily time spent using the internet for the group with probable internet addiction were significantly higher than those of the group without probable internet addiction (50%; P<.001). The total difficulties score from the SDQ for the group with probable internet addiction (mean 10.87, SD 5.9) was significantly higher than that for the group without probable internet addiction (mean 8.23, SD 5.64; P<.001). The mean score for authoritarian parenting from the PSDQ for the group with probable internet addiction (mean 2.1, SD 0.58) was significantly higher than that for the group without probable internet addiction (mean 2.1, SD 0.58; P<.001). Regarding the RQ, there were no significant differences between the two groups. Conclusions: Our findings suggest that parents who think their child is addicted to the internet may recognize emotional and behavioral problems of the child and have an authoritarian parenting style.
