Physical activity and physical fitness as protective factors of adolescent health

This quantitative correlational design study aimed to examine the variation in adolescent health and lifestyle characteristics across self-reported physical activity (PA) and physical fitness (PF) levels.

Data were collected from 422 students (50.2% males) (16.33 SD = 1.66 y/o) attending a high school. An online questionnaire was used to gather data on the following characteristics: self-reported well-being, overall life satisfaction, depression (including self-harm and suicidal ideation), perceived health status, eating disorders, sleepiness, substance use (alcohol, tobacco and illicit drug use), body mass index, PA participation and PF levels.

Of the participants, 42.4% reported at least 5 days of PA a week for 60 min per day. These high active individuals had significantly better well-being, health status, life satisfaction, PF and consumed fewer alcohol beverages. High PA and better PF inversely correlated with depression.

It seems that high PA and better PF have a positive impact on adolescent perceived health, health-risk behaviors and mental health. Increased levels of PA can play a vital role in the primary care, prevention of health risks and in adolescent health promotion. Accordingly, educational institutions are an excellent setting to promote and provide sport facilities and encourage students to be more physically active.
