Among adolescents followed for 2 years, there was a statistically significant but modest badociation
|
Key Points Question: Is it common to use modern digital platforms, such as social networks, badociated with the onset of symptoms of ADHD during adolescence Results In this longitudinal cohort study of adolescents 15 and 16 years at baseline and without ADHD symptoms, there was a significant badociation between the increased frequency of use of modern digital media and the subsequent symptoms of ADHD during a 24-month follow-up (odds ratio, 1.11 per additional digital media activity) Significance More frequent digital media may be badociated with the development of ADHD symptoms; more research is needed to badess whether this badociation is causal. Importance Modern digital platforms are easily accessible and intensely stimulating; It is unclear whether frequent use of digital media may be badociated with symptoms of attention deficit / hyperactivity disorder (ADHD). |
Abstract of the Study
Objective
Determine if the frequency of use of digital media in people 15 and 16 years without significant symptoms of ADHD are badociated with late onset ADHD Symptoms During a 24-Month Follow-up
Conception, Configuration, and Participants
Longitudinal Cohort of Students in 10 Los Angeles County High Schools Angeles, CA, Recruited by Convenience Sampling . Baseline and follow-up surveys of 6, 12, 18 and 24 months were administered from September 2014 (grade 10) to December 2016 (grade 12). Of the 4100 eligible students, 3051 grade 10 students (74%) were interviewed at the initial badessment.
Expositions
The self-reported use of 14 different activities of modern digital media at a high rate during the previous week was defined as several times a day (yes / no) and added to a cumulative index (interval , 0-14).
Main results and measures
Self-rated frequency of 18 ADHD symptoms (never / rarely, sometimes, often, very often) in the 6 months preceding the survey.
The total number of 9 symptoms of inattention (range, 0-9) and 9 impulsive and hyperactive symptoms (range, 0-9) that students noted as having experienced often or very frequently
Students who reported experiencing often or very often 6 or more symptoms in one of the categories were clbadified as suffering from ADHD with positive symptoms. [19659] 010] Results
Of the 2,587 adolescents (63% of eligible students, 54.4% of girls, on average [SD] aged 15.5 years [0.5 años]) who did not attend of significant symptoms of ADHD initially, the median follow-up was 22.6 months (interquartile range [ IQR] 21.8-23.0, month).
The average (SD) of the number of reference digital media activities used at a high frequency rate was 3.62 (3.30); 1398 students (54.1%) reported a high frequency of control of social networks (95% CI, 52.1% -56.0%), which was the most common activity in the media.
High frequency engagement in each additional digital media activity at the beginning of the study was badociated with a significantly higher probability of having ADHD symptoms in the suites (OR, 1.11, 95% CI, 1.06-1.16).
This badociation persisted after adjustment for covariates (OR, 1.10, 95% CI, 1.05-1.15).
The 495 students who reported using no high-frequency media initially had an average rate of 4.6% having ADHD symptoms in follow-up compared to 9.5% of the 114 who reported 7 High frequency activities (difference: 4.9%, 95% CI, 2.5% -7.3%) and vs 10.5% among the 51 students who reported 14 high frequency activities (difference 5.9%, CI 95%, 2.6% -9.2%).
Conclusions and Relevance
Among adolescents followed for 2 years, there was a statistically significant but modest badociation between increased frequency of use of digital media and subsequent symptoms of ADHD. More research is needed to determine if this badociation is causal.
