Question Description

I need help with a Health & Medical question. All explanations and answers will be used to help me learn.


Please note that each and every assignment has its own word limit.

The word cohort is a group of people that share characteristics. So cohort studies are a type of medical research used to investigate the causes of disease and to establish links between risk factors and health outcomes. It is a particular form of longitudinal study that samples a cohort typically those who experienced a common event in a selected period, such as birth or graduation, performing a cross-section at intervals through time.

Mental illness is a health condition that is extremely common but is constantly going unnoticed. The cohort study of the relationship between mental illness and physical activity. The participants' treatment group are 928 12–13 year olds in the UK. These participants were in the Activity and Healthy Eating in Adolescence trial (AHEAD) trial and were observed over 3 years. The physical activity was measured using accelerometers. At follow-up, mental wellbeing was measured using the ‘Warwick Edinburgh Mental Wellbeing Scale’ (WEMWBS) and symptoms of mental health disorder using the ‘Strengths and Difficulties Questionnaire’ (SDQ) (Bell, Audrey, Gunnell, Cooper, & Campbell 2019.)The analyses assessed the association between physical activity and the measures of mental wellbeing and symptoms of mental health disorder.This cohort study found no strong evidence that physical activity is associated with better mental wellbeing or reduced symptoms of mental health disorder in adolescents. However, a protective association between physical activity and the emotional problems subscale of the SDQ was found.

A cohort study described as an observational study rather than an experimental study because an observational study is a study where researchers simply collect data based on what is seen and heard and infer based on the data collected.Observational studies are ones where researchers observe the effect of a risk factor, diagnostic test, treatment or other intervention without trying to change who is or isn’t exposed to it.
