Study Notes
Defining Depression
- Depression encompasses depressive symptoms and clinically diagnosed mood disorders (e.g., bipolar).
- It is distinct from negative moods.
- Prevalence in Canada:
- 7% of the population meets criteria for clinical depression.
- 15% will meet criteria at least once in their lifetime.
- During COVID-19, 15% met criteria for clinical depression.
Diagnosing Major Depressive Disorder
- DSM-V: Diagnostic and Statistical Manual for Mental Disorders. Diagnosis based on the number of depressive episodes.
- ICD-10: International Classification of Diseases—10. Severity levels (mild, moderate, or severe) are used to diagnose.
Beck Depression Inventory (BDI)
- A self-administered tool for diagnosing major depressive disorder (MDD).
- Determines likelihood of MDD based on cut-off scores (likely or unlikely).
- Not a definitive diagnostic tool, used for screening.
- High reliability and validity for research studies.
Exercise as Prevention for Depression
- Distinct from treatment, exercise can prevent depression.
- Exercise promotes preventative measures rather than treatment for existing symptoms.
Prevalence of Major Depressive Disorder
- Based on self-reported physical activity.
- Exhibit 11.4 shows prevalence rates associated with different frequencies of physical activity.
- There is a linear relationship between the frequency of physical activity and the prevalence of MDD.
- Individuals with MDD have a 50% lower likelihood of meeting recommended physical activity levels compared to those without MDD.
Physical Activity and Prevention of Depression
- A systematic review of prospective studies examined the protective effect of physical activity on depression.
- Participants were tracked over time, and exercise levels were examined to predict depressive symptoms.
- All participants did not have depression at baseline.
Physical Activity and Risk of Depression
- 25 studies demonstrated that baseline physical activity (PA) was negatively associated with depression risk.
- Promoting PA can be a valuable mental health strategy for reducing depression risk.
- Mixed findings regarding the amount of PA needed to be protective.
- Three high-quality studies measuring PA (minutes per week) found that less than 150 minutes of moderate-to-vigorous PA per week was associated with a decreased risk of developing depression.
- 120 minutes of PA per week was linked to a 63% reduced risk of future depression.
- Walking 20-40 minutes a day at an average pace showed a reduced risk of depression.
Meta-analysis: Physical Activity and Incident Depression
- People with higher physical activity levels had a reduced risk of incident depression compared to those with lower levels.
- Higher intensity physical activity was associated with a lower incidence of depression, particularly in adults and older adults.
- Protective effects were observed in children when adjusted odds ratio and relative risk analysis were used.
Meta-analysis: Exercise Interventions for Depression Prevention
- A systematic review of meta-analyses of randomized trials published up to July 2018 examined the effects of exercise interventions on depression.
Summarizing PA studies on Depression
- Ample, consistent, and high-quality evidence supports the use of physical activity in preventing and protecting against depression.
- The optimal type, duration, and intensity of PA for depression prevention are not yet fully understood.
- Any amount of PA appears beneficial.
Defining Usual Treatment for Depression
- Medications, psychotherapy, or a combination of both.
- Alleviation of symptoms in 30% of cases.
Effectiveness of Physical Activity Interventions
- Physical activity interventions, to improve depression, anxiety, and distress, involve increasing PA levels in populations.
- The interventions are designed to increase PA and potentially improve participant mental health.
Importance of Self-Compassion
- Self-compassion is a new way of thinking about oneself, offering benefits of self-esteem without risks.
- Self-compassion is kind, caring, and non-judgmental, with an awareness of one's physiological states and environment
Importance of Self-Esteem
- The self-concept, including self-esteem, is hierarchical and multi-dimensional.
- Self-esteem and self-concept are based on childhood development.
- Self-esteem is evaluative, affecting one's self-perception and feelings.
- High self-esteem is associated with better outcomes in life (social, mental, and physical).
- Negative reflections on self-worth can be detrimental if they are frequent or strong.
Exercise and Affect
- Affect (positive or negative mood) is related to physical activity.
- It plays a part in exercise adherence and intensity choices.
- Exercise participation influences emotional well-being.
- The intensity of exercise affects affective response.
Exercise and Self-Esteem
- Exercise participation affects self-efficacy, and that improvement leads to increased self-esteem.
- The effects of exercise on self-esteem are influenced by factors like frequency, intensity, duration, type, and the length of program.
- Self-esteem improvements were significantly larger if physical fitness also improved.
- The duration of exercise was not a significant influence on self-esteem outcomes.
Body Image and Exercise
- Body image is multi-dimensional (perceptual, cognitive, emotional, behavioural). These facets can relate to how individuals perceive themselves, and in comparison to others.
- Exercise can change body image perceptions.
- A positive correlation is noted between exercise participation and changes to one's body image
- In interventions targeted at girls and women, exercise strongly improved body image.
Measuring Physical Activity
- Self-reported: Widely used due to cost-effectiveness and ease of administration. Includes daily activity logs, and physical activity recall. Can be prone to biases (e.g., social desirability).
- Objective/device-based: Use mechanical and electronic devices (e.g., heart rate monitors, pedometers, accelerometers, GPS). Less prone to biases than self-reported measures but more expensive.
- Observational: Directly viewing exercise behavior. Effective for eliminating self-report biases but can include observer bias.
