The buffer effect of physical activity: Why does parental marital satisfaction affect adolescents' problematic Internet use.

ABSTRACT: Introduction:To explore the moderating effect of physical activity and the mediating effect of depression on the relationship between marital satisfaction and adolescents' problematic internet use (PIU). Methods:This study adopted a sample of 288 adolescents and their parents, and measured adolescents' depression, PIU, physical activity, and parents' marital satisfaction. Results:These results showed that parental marital satisfaction negatively predicted adolescents' PIU. Adolescents' depression played a mediating role between parental marital satisfaction and adolescents' PIU. Further mediated moderation effect analysis showed that the interaction between marital satisfaction and adolescents' physical activity affected the PIU through adolescents' depression. Specifically, for individuals with lower physical activity, the marital satisfaction affected the PIU through adolescents' depression. However, for the group with higher physical activity, physical activity weakened the effects of marital satisfaction on adolescents' depression, and the mediating effect of depression did not reach a significant level. Conclusion:These results are of theoretical and practical significance in understanding and intervening to address adolescents' PIU.

Project description:BackgroundGiven the growing number of adolescents exhibiting problematic internet use (PIU) and experiencing its harmful consequences, it is important to examine the factors associated with PIU. Existing research has identified perceived parental supportiveness and adolescents' subjective mental well-being as strong predictors of PIU. However, it is unknown how these factors work together in shaping adolescents' engagement in PIU.ObjectiveThis paper aimed to examine the role played by adolescents' perception of parental supportiveness in conjunction with their subjective mental well-being in shaping their PIU.MethodsThe study analyzed one of the Technology & Adolescent Mental Wellness (TAM) data sets that were collected from a nationally representative cross-sectional sample. Adolescents self-reported their internet use behavior, perceived parental supportiveness, and subjective mental well-being through an online research panel survey. Hierarchical linear regression analysis with an interaction term was performed.ResultsA total of 4592 adolescents, aged 12 to 17 years, completed the survey. Adolescents reported a mean age of 14.61 (SD 1.68) and were 46.4% (2130/4592) female and 66.9% (3370/4592) White. Findings revealed that, controlling for adolescents' demographics and social media use, higher levels of perceived parental supportiveness (β=-.285, P<.001) and higher levels of subjective mental well-being (β=-.079, P<.001) were associated with a lower likelihood of adolescent PIU. The moderation analysis showed that the negative association between perceived parental supportiveness and PIU was stronger when adolescents reported high (vs low) levels of mental well-being (β=-.191, P<.001).ConclusionsThis study shows that perceived parental supportiveness was a stronger protective factor than adolescents' mental well-being against PIU. The protective power of perceived parental supportiveness against PIU was strongest when adolescents had high mental well-being. The highest risk of PIU occurred when adolescents' mental well-being was high, but parents were perceived as unsupportive. Our findings suggest that parental supportiveness should be targeted as part of PIU prevention efforts.

Project description:Few studies have prospectively investigated whether early-life exposures are associated with pre-adolescent eating attitudes.The objective of this study is to prospectively investigate associations of parental smoking, alcohol use, marital status, measures of maternal satisfaction, self-reported parental body mass index (BMI) and clinically measured childhood BMI, assessed between birth and 6.5 years, with problematic eating attitudes at 11.5 years.Observational cohort analysis nested within the Promotion of Breastfeeding Intervention Trial, a cluster-randomised trial conducted in 31 maternity hospitals and affiliated polyclinics in Belarus. Our primary outcome was a Children's Eating Attitudes Test (ChEAT) score ?22.5 (85th percentile), an indicator of problematic eating attitudes. We employed multivariable mixed logistic regression models, which allow inference at the individual level. We also performed instrumental variable (IV) analysis using parents' BMIs as instruments for the child's BMI, to assess whether associations could be explained by residual confounding or reverse causation.Of the 17?046 infants enrolled between 1996 and 1997 across Belarus, 13?751 (80.7%) completed the ChEAT test at 11.5 years.In fully adjusted models, overweight children at age 6.5 years had a 2.14-fold (95% confidence interval (CI): 1.82, 2.52) increased odds of having ChEAT scores ?85th percentile at age 11.5 years, and those who were obese had a 3.89-fold (95% CI: 2.95, 5.14) increased odds compared with normal-weight children. Children of mothers or fathers who were themselves overweight or obese were more likely to score ?85th percentile (P for trend ?0.001). IV analysis was consistent with a child's BMI causally affecting future eating attitudes. There was little evidence that parental smoking, alcohol use, or marital status or maternal satisfaction were associated with eating attitudes.In our large, prospective cohort in Belarus, both parental and childhood overweight and obesity at 6.5 years were associated with pre-adolescent problematic eating attitudes 5 years later.
