“…The present study found that the risk of EPD increased three times in girls who spent more than 7 h per week on electronic screen, and it supported the above view 18 . The mechanisms of light exposure correlating with early signs of maturity have not been confirmed among human beings, but they have been explained by animal studies, including sleep disruption and melatonin theory 15 . Sleep disruption could result in lack of sleep which is correlated with weight gain, and weight gain is correlated with early puberty 15 .…”

“…Previous studies have observed that early-onset puberty is often associated with excess body weight, especially in girls 12 – 14 . Lifestyle habits including physical activity and electronic screen time (EST) are also potential influencing factors of EPD 15 – 17 , but the evidence are still insufficient. A study presented at the 60 th Annual European Society for Pediatric Endocrinology Meeting in Rome suggested that the increase of precocious puberty during the pandemic of COVID-19 might be resulted from unhealthy lifestyles including long time spent on smart devices 18 .…”

To examine the joint association of electronic screen time (EST), moderate-to-vigorous physical activity time (MVPA) and overweight/obesity with early pubertal development (EPD) in girls. A case–control study of 177 EPD girls and 354 girls with normal pubertal development was conducted between October 2019 and August 2022. Overweight/obesity was defined as body mass index ≥ 85th percentiles for age and sex. We found a non-significant increase of EPD risk among girls with high EST alone [OR: 2.75 (0.65–11.58)] or low MVPA alone [OR: 2.54 (0.74–8.69)], but a significant increase of EPD risk among girls with overweight/obesity alone [OR: 4.91 (1.01–23.92)], compared to girls without any of the three risk factors (low MVPA, high EST and overweight/obesity). Girls with any two of the three risk factors faced increased risk of EPD, and girls with all three risk factors faced the highest risk of EPD [OR and 95% CI: 26.10 (6.40–106.45)]. Being overweight/obesity might be more important than having low MVPA or high EST as a correlate of EPD compared to girls without any of the three risk factors, but the co-presence of low MVPA, high EST and overweight/obesity would largely increase the risk of EPD in girls.

Background This study examined the relationship between touchscreen exposure and developmental outcomes in early childhood using the Ages and Stages Questionnaire, Third Edition (ASQ-3), a widely-used developmental screening tool. Methods During a well-child visit, parents of 51 children aged 18-36 months completed the ASQ-3 and a survey on their child's touchscreen habits (timing of introduction, daily usage duration, independent use, engagement in creative activities). Medical records were reviewed for developmental diagnoses and health conditions. Analysis One-way analysis of variances (ANOVAs) examined differences in ASQ-3 domain scores (problem-solving, personal-social, communication, gross motor, fine motor) based on the age of touchscreen introduction and average daily usage time. Independent t-tests compared scores between groups defined by independent touchscreen use and creative activity engagement. Effect sizes were calculated for significant differences. Results In the problem-solving domain, children introduced to touchscreens before 12 months of age scored significantly higher than those introduced later, with a statistical significance of p<0.05 and an effect size of d=0.45. However, there were no significant differences in scores based on the duration of daily touchscreen usage. In the personal-social domain, children introduced to touchscreens at 12 months or later scored significantly higher than those introduced before 12 months, with a significance of p<0.05 and an effect size of d=0.51. Moderate daily usage of 30-90 minutes was associated with higher scores compared to lower usage of less than 30 minutes or higher usage of more than 90 minutes (p<0.05). Additionally, children who used touchscreens independently had significantly higher scores, with a significance of p<0.01 and an effect size of d=0.76. Those who engaged in activities such as coloring or crafting also had significantly higher scores, with a significance of p<0.01 and an effect size of d=0.82. In other domains, such as communication, gross motor, and fine motor, no significant effects of touchscreen exposure were observed. Discussion Earlier touchscreen introduction may facilitate problem-solving skills like experimentation and cognitive flexibility through interactive digital play. However, excessive touchscreen use (greater than 90 minutes per day) before 12 months could interfere with pivotal social-emotional learning from real-world interactions, impeding personal-social development. Moderate, supervised touchscreen exposure combined with creative hands-on activities appears optimal for fostering strong personal-social competencies like cooperation and emotional understanding during the toddler years. Conclusion Timing, duration, context, and content of touchscreen experiences in early childhood relate differently to specific developmental domains. Guidelines should consider these nuances to support...
