Subjects and procedures
Data were retrieved from the longitudinal eating and activity study conducted from 2002 (baseline) to 2012 (follow-up) in Flanders (Belgium). At baseline, 100 randomly selected schools were contacted, whereas 59 schools agreed to participate. Students from the fifth grade of these 59 primary schools were invited to participate in the longitudinal study (n = 1,957). Children recruited were, on average, 9.9 years (±.43) old at baseline and 19.9 years (±.43) old at follow-up. The detailed
Results
At baseline, 11.60% and 40.50% of the total group exceeded the ST guideline (>2 hours/day) on weekdays and weekends, respectively. At follow-up, 50.80% and 64.20% of the total group (on weekdays and weekends, respectively) exceeded this guideline. More detailed information (i.e., gender-specific results) is provided in Table 2.
Discussion
The present study investigated predictors and tracking of ST during a 10-year follow-up period, resulting in information on the transition from early adolescence into early adulthood, which is a critical period in life. Different predictors, measured at the age of 10 years, emerged for TV and PC time at the age of 20 years. The predictors were different for gender and type of day (weekday vs. weekend). Furthermore, the tracking results were only significant for boys, and ST was found to be most

Correlates of screen time in the early years (0–5 years): A systematic review
2023, Preventive Medicine ReportsAssociation of mentally-active and mentally-passive sedentary behaviour with depressive symptoms among adolescents
2021, Journal of Affective DisordersCitation Excerpt :Obesity is associated with depressive symptoms (Köhler et al., 2018; Mannan et al., 2016) and has been suggested to mediate the association between types of sedentary behaviour and depressive symptoms (de Jong et al., 2013). Lastly, sedentary behaviour has a moderate tracking during adolescence, thus, higher sedentary behaviour during early adolescence is associated with a higher sedentary behaviour during mid-adolescence (Biddle et al., 2010; Busschaert et al., 2015). This can be a pathway linking sedentary behaviour during early adolescence to later depressive symptoms.

2020, Preventive MedicineCitation Excerpt :However, these increases differed according to the adolescents' sex. Our findings are consistent with other studies (Bucksch et al., 2016; Twenge et al., 2019; Busschaert et al., 2015), that also show that boys increased their total screen time more than girls. Boys increased time using electronic-games, while this decreased in girls.
Tracking of Physical Activity and Sedentary Behavior From Adolescence to Young Adulthood: A Systematic Literature Review
2019, Journal of Adolescent HealthCitation Excerpt :The only study using objective methods to assess both PA and SB had a moderate methodologic quality score of 78.9% [12]. One study [21], reporting solely on screen time as a surrogate measure of SB, was deemed to have a high methodologic quality score (89.4%). As there was considerable heterogeneity of the data in terms of analysis methods, age of adolescents and adults participating in the studies and length of follow-up, statistical pooling of the results were not possible.
Longitudinal Sedentary Time Among Females Aged 17 to 23 Years
2019, American Journal of Preventive MedicineCitation Excerpt :The studies that have evaluated youth and adults’ longitudinal sedentary behavior are largely atheoretic, with few associations found,13–15 or focus mainly on associations of sedentary time and adiposity.14,16,17 Of studies that used a theoretic basis for selecting predictors of longitudinal sedentary behavior, most have employed socioecologic models.18–20 High BMI was associated with greater sedentary time in young adult women,20 but other studies found it was not in adolescent girls.18,19
