Why the study?

Mental health among young people is deteriorating, but methodological issues with study design and physical activity measurement limit understanding of its prospective relationship with mental health.

Do changes in objectively measured physical activity or sedentary behavior affect mental wellbeing and mental health problems in adolescents?

Population

599 adolescents (mean age 13.3 ± 0.3 years, 54.4% female) at lower secondary school in Norway

Comparison

Changes in total PA, MVPA, and sedentary behaviour

Design

Prospective longitudinal study

Follow-up

3 years

Overview

Sex-specific associations with wellbeing but not problems should not change practice; leaves open causal effects in adolescents.

Structured PICO

Do changes in objectively measured physical activity or sedentary behavior affect mental wellbeing and mental health problems in adolescents?

P
Population
599 adolescents (54.4% female, mean age at baseline 13.3 ± 0.3 years) in lower secondary school in Norway.
I
Intervention
Changes in objectively measured physical activity (total volume, moderate-to-vigorous intensity, and sedentary behavior) using accelerometry over 3 years.
O
Outcome
Mental wellbeing (measured by Warwick-Edinburgh Mental Wellbeing Scale) and mental health problems (measured by Strengths and Difficulties Questionnaire) at 3 years.patient reported

Changes in physical activity and sedentary behavior showed small, sex-specific associations with mental wellbeing but not mental health problems in healthy adolescents.
