Relationship between screen time and nutrient intake in Japanese children and adolescents: a cross-sectional observational study

Abstract

BackgroundSedentary behaviors have recently become an important public health issue. We aimed to investigate the relationship between screen time and nutrient intake in children and adolescents.MethodsThe present study was conducted in 2013. Data were collected from children and adolescents aged between 6 and 15 years old in Shika town. Questionnaires were distributed to 1459 subjects, 1414 of whom participated in the study (96.9%). Sedentary behaviors were assessed based on participants’ screen behaviors (television (TV) viewing, personal computer (PC) use, and mobile phone (MP) use). The main outcomes were the intake of nutrients from a validated food frequency questionnaire. Analysis of covariance (ANCOVA) was used to examine the significance of differences in nutrient intake estimates. Multivariate linear regression analyses, adjusting for age, BMI, and physical activity, were used to provide parameter estimates (β) and 95% CI for the relationship between screen time and nutrient intake.ResultsIn boys, longer TV viewing times correlated or tended to correlate with a lower intake of protein, potassium, calcium, iron, vitamin K, vitamin B-2, and total dietary fiber. In girls, longer TV viewing times correlated with a lower intake of protein, sodium, calcium, vitamin D, and vitamin B-2. Longer TV viewing times correlated with a higher intake of n-6 fatty acids in girls. PC use was related or tended to be related to a lower intake of potassium, iron, vitamin K, and folic acid in boys, but not in girls. A relationship was observed between MP use and a lower intake of vitamin K in boys, and MP use and a higher intake of vitamin D in girls.ConclusionsThe present results revealed that longer TV viewing times are associated with less protein, minerals, vitamins, and total dietary fiber intake in children and adolescents. It was also revealed that boys with PC use have less minerals and vitamins. These results support the need to design intervention programs that focus on decreasing TV viewing time in both sexes and PC use in boys while encouraging adherence to dietary guidelines among children and adolescents.

Association between standardized vitamin 25(OH)D and dyslipidemia: a community-based study in Riyadh, Saudi Arabia

“…In females, the association between HDL and vitamin D deficiency, which was significant on univariate analysis, became insignificant after adjusting for vitamin D supplementation (around 20% (n = 207) of the females were taking vitamin D supplements). Unhealthy lifestyle, with lack of PA and increased screening time, is also associated with low vitamin D intake [43].…”

Seelische Gesundheit und psychische Belastungen von Kindern und Jugendlichen in der ersten Welle der COVID-19-Pandemie – Ergebnisse der COPSY-Studie

“…[ 35 ] beschrieben. Eine frühere Studie zeigt, dass ein verstärkter Medienkonsum auch mit Veränderungen von Essgewohnheiten einhergehen kann und somit das Risiko für Übergewicht und zugehörige Folgeerkrankungen steigen kann [ 36 ]. Eine weitere Studie zur Mediensucht bei Kindern während der COVID-19-Pandemie weist darauf hin, dass ein Medienmissbrauch nicht nur Schlafgewohnheiten negativ beeinflussen, sondern sich auch negativ auf die Lebensqualität auswirken kann.…”

The Prevalence and Associated Factors of Screen Time Among Intermediate School Students in Makkah Al-Mokarramah, Saudi Arabia, 2019.A Crosssectional Study.

“…Since technology-based inactive behaviors change quickly, the association between new types of sedentary behaviors among adolescents needs to be assessed (16). Therefore, the present study aimed to assess the screen-time and to determine the factors associated with it among intermediate school students in Makkah Al-Mokarramah City, Saudi Arabia.…”
