FINLAND - Tablet tantrums: Toddlers use of screens leads to behavioral problems in the classroom, Finnish study finds [RT, 2021]

Title:
Tablet tantrums: Toddlers use of screens leads to behavioral problems in the classroom, Finnish study finds

Published:
RT, 18 March 2021

From the article:
Scientists say preschoolers who frequently play with tablets or other electronic media have a greater chance of being hyperactive. A short attention span and an inability to concentrate are also more common, and the e-toddlers will have difficulty relating to other children when they’re old enough to go to school.

Abstract:
Objectives 
This study investigated the frequency of electronic media (e-media) usage by preschool children and the risks of high-dose e-media use on young children’s psychosocial well-being.  
 
Design 
Longitudinal associations between e-media use at 18 months and psychosocial symptoms at 5 years of age were studied, as well as cross-sectional associations between e-media use and psychosocial symptoms at 5 years.  
 
Setting 
Between 2011 and 2017 in Finland.  
 
Participants 
Children aged 5 years (n=699).  
 
Primary and secondary outcome measures 
Children’s psychosocial symptoms were determined at the age of 5 years using the parent-reported questionnaires Five-to-Fifteen (FTF) and the Strengths and Difficulties Questionnaire (SDQ).  
 
Results 
Based on our results, 95% of the preschool children exceeded the daily recommended use of e-media set by health professionals. Our results indicate that increased screen time at 5 years of age is associated with a risk of multiple psychosocial symptoms (OR 1.53–2.18, 95% CI 1.05 to 3.34, p<0.05), while increased levels of e-media use at 18 months was only associated with FTF peer problems (OR 1.59, 95% CI 1.04 to 2.41, p=0.03). Moreover, high-dose use of electronic games at the age of 5 years seems to be associated with fewer risks for psychosocial well-being than programme viewing, as it was only associated with SDQ hyperactivity (OR 1.65, 95% CI 1.08 to 2.51, p=0.02).  
 
Conclusion 
Increased screen time has multiple risks for children’s psychosocial well-being. These risk factors seem to be significant in the long term, and are related to problems in children’s socio-emotional development later on. Health professionals and paediatricians have an important role as communicators of the current research results on the safe usage time of e-media for families, and enhancing parents’ skills as regulators of children’s safe e-media use. More research is needed on the family conditions of high-dose e-media users.

Consumption of dietary nuts in midlife and risk of cognitive impairment in late-life: the Singapore Chinese Health Study [Scholarly Article - Age and Ageing, 18 December 2020]

Abstract:
Background 
evidence from prospective studies investigating the association between consumption of nuts in midlife and risk of cognitive impairment in late life is limited.  
 
Methods 
this study analysed data from 16,737 participants in a population-based cohort, the Singapore Chinese Health Study. Intake of nuts was assessed using a validated food-frequency questionnaire at baseline (1993–1998), when participants were 45–74 years old (mean age = 53.5 years). Cognitive function was tested using the Singapore modified Mini-Mental State Examination during the third follow-up visit (2014–2016), when participants were 61–96 years old (mean age = 73.2 years). Cognitive impairment was defined using education-specific cut-off points. Logistic regression models were used to estimate the odds ratio (OR) and the 95% confidence interval (CI) for the association between intake and risk of cognitive impairment.  
 
Results 
cognitive impairment was identified in 2,397 (14.3%) participants. Compared with those who consumed <1 serving/month of nuts, participants who consumed 1–3 servings/month, 1 serving/week and ≥2 servings/week had 12% (95% CI 2–20%), 19% (95% CI 4–31%) and 21% (2–36%) lower risk of cognitive impairment, respectively (P-trend = 0.01). Further adjustment for intake of unsaturated fatty acids attenuated the association to non-significance. Mediation analysis showed that the 50.8% of the association between nuts and risk of cognitive impairment was mediated by the intake of total unsaturated fatty acids (P < 0.001).  
 
Conclusion 
higher intake of nuts in midlife was related to a lower risk of cognitive impairment in late life, which was partly mediated by unsaturated fatty acids.
