Title: The Impact of Physical Activity, Screen Time, and Sleep on Mental Health in Children and Adolescents: A 3-Month Study
Mental health issues among children and adolescents have become a growing concern in recent years. Depression, in particular, is a prevalent condition that can significantly impact the overall well-being and development of young individuals. Accordingly, understanding the potential factors that may contribute to improved mental health outcomes is crucial. This study aims to examine the association between achieving high levels of physical activity, decreasing screen time, and getting sufficient sleep with better mental health among children and adolescents over a 3-month period.
Participants in this study consist of adolescents diagnosed with depression, who are attending either a primary care clinic or a mental health outpatient clinic. The study employs a quasi-experimental design, with an intervention group (IG) and a control group (CG). The IG receives interventions aimed at increasing physical activity levels, reducing screen time, and ensuring adequate sleep hours, whereas the CG maintains their sedentary lifestyle behaviors.
The primary outcome measure in this study is the reduction in depressive symptoms and the improvement of overall mental health, assessed using standardized, psychometrically sound instruments administered at the beginning and end of the 3-month period.
Preliminary results indicate a notable association between increased physical activity, decreased screen time, and sufficient sleep with improved mental health among children and adolescents diagnosed with depression. An analysis of the intervention group’s data reveals a significant reduction in depressive symptoms and improved overall mental health compared to the control group.
Physical activity has been shown to positively impact mental health by releasing endorphins, improving mood regulation, and reducing anxiety and depressive symptoms (Craft & Perna, 2004). Additionally, physical activity provides social engagement opportunities, leading to increased self-esteem and a sense of belonging, which are essential factors for positive mental health outcomes (Payne et al., 2020).
Similarly, excessive screen time has been linked to a range of negative mental health consequences, including increased depressive symptoms, poor self-esteem, and inadequate emotional regulation (Hutton et al., 2016; Twenge et al., 2018). Decreasing screen time may contribute to improved mental health outcomes by reducing exposure to potentially harmful content and fostering healthier social interactions.
Sufficient sleep is critical for cognitive function and emotional well-being, particularly during adolescence when biological changes affect sleep patterns (Carskadon et al., 2004). Lack of sleep has been associated with increased depressive symptoms, impaired emotional regulation, and cognitive difficulties, all of which can significantly impact mental health outcomes in children and adolescents (Fuhr et al., 2016; Riemann et al., 2020).
The findings of this study support the hypothesis that achieving high levels of physical activity, decreasing screen time, and getting sufficient sleep correlate with improved mental health outcomes among children and adolescents diagnosed with depression. This study adds to the existing literature by providing evidence for the potential benefits of lifestyle modifications in the management of mental health conditions in young individuals.
The positive association between physical activity and mental health has been well-documented, and implementing physical activity interventions, such as exercise programs or sport participation, may be beneficial as adjunct therapies in treating depression among children and adolescents (Stubbs et al., 2018). Furthermore, initiatives focusing on reducing screen time and promoting healthier sleep habits should be encouraged at various levels, including schools and families, to help mitigate mental health issues.
In conclusion, this study highlights the importance of addressing lifestyle factors, including increasing physical activity, reducing screen time, and ensuring adequate sleep, in promoting better mental health outcomes among children and adolescents diagnosed with depression. The findings underscore the potential role of lifestyle modifications as complementary interventions for managing mental health conditions in this population. Further research is needed to explore the long-term impact of these lifestyle changes on mental health outcomes and to determine the most effective strategies for implementation.
