Item Screen addiction among children and adolescents and the self-efficacy of mothers in screen use management during the COVID-19 lockdown in Sri Lanka(Sri Lanka College of Psychiatrists, 2023) Baminiwatta, A.; Nanayakkara, T.D.; Fernando, A.; Wijethunga, S.BACKGROUND: The prevalence of problematic screen use (PSU) or “screen addiction” among children and adolescents may have escalated during the COVID-19 pandemic. The self-efficacy of the mothers in managing screen use in their children may play an important preventive role in children developing PSU. AIMS: This study aimed to assess PSU among children aged 4-18 years during the lockdown period imposed during the COVID-19 pandemic and to explore the association between PSU and self-efficacy of mothers in managing screen use. METHODS: An online survey was conducted using social media groups among mothers of children aged 4-18 years. The PSU in their children was measured using the Problematic Media Use Measure (PMUM), and maternal self-efficacy in managing screen use was assessed using the Parental Screen Use Management Scale (PSUMS). The two questionnaires were translated and validated into Sinhala prior to this study. RESULTS: A total of 320 mothers responded to the survey. Based on the PMUM cut-off score, 25.3% of the children were found to have PSU. PSU was inversely correlated with maternal self-efficacy in managing screen use (r=-0.63, p<0.001). All three subscales of the PSUMS; reactive management (r=-0.56, p<0.001), proactive management (r=-52, p<0.001), and monitoring (r =-45, p<0.001), were significantly correlated with PSU. Younger age at screen use onset showed a marginal correlation (rho=-0.11, p=0.05) with PSU. The child’s age, gender and the educational level of the mother were not associated with PSU. CONCLUSION: Maternal self-efficacy in managing screen use among children was associated with lower PSU in children.Item 24 h activity guidelines in children and adolescents: A prevalence survey in Asia-Pacific cities(MDPI, 2023) Quah, P.L.; Loo, B.K.G.; Mettananda, S.; Dassanayake, S.; Chia, M.Y.H.; Chua, T.B.K.; Tan, T.S.Z.; Chan, P.C.; But, B.W.; Fu, A.C.; Wong, S.M.; Nagano, N.; Morioka, I.; Kumar, S.; Nair, M.K.C.; Tan, K.H.This study aimed to examine the prevalence of adherence to 24 h activity guidelines in children and adolescents from Asia-Pacific cities. In 1139 children aged 5-18 years, moderate-to-vigorous physical activity (MVPA), screen viewing time (SVT), sleep duration, child weight, height, sex, and age were parent-reported. Descriptive statistics were used to assess the number of guidelines met, and prevalence of adherence to activity guidelines by city and child sex. Prevalence of meeting all three 24 h activity guidelines was low across all countries (1.8-10.3%) (p < 0.05). Children from Thiruvananthapuram, India had the highest [10.3% (95% CI: 6.0-17.0)], while those from Tokyo, Japan had the lowest prevalence [1.8% (95% CI: 0.5-7.0)] of meeting all three guidelines. The highest prevalence of meeting individual MVPA, SVT and sleep guidelines was found in India [67.5% (95% CI: 58.8-75.1)], Kelaniya, Sri Lanka [63.2% (95% CI: 58.7-67.4)] and Kowloon, Hong Kong [59.4% (95% CI: 51.1-65.3)], respectively. Overall, a higher prevalence of boys met all three guidelines, compared to girls [5.9% (95% CI: 4.1-8.1) vs. 4.7% (3.1-6.6), p = 0.32]. The prevalence of adhering to all three activity guidelines was low in all five participating cities, with a higher proportion of boys meeting all guidelines.
