Objectively measured physical activity among treatment seeking children and adolescents with severe obesity and normal weight peers.

Background: Treatment seeking children and adolescents with severe obesity often experience barriers to physical activity. Studies objectively measuring physical activity in this group and investigating explanatory factors for physical activity levels could inform clinical practice.

Objectives: This study aimed to compare objectively measured physical activity levels among treatment seeking children and adolescents with severe obesity and normal weight peers, and to investigate explanatory factors for time spent in moderate physical activity and vigorous physical activity among children and adolescents with severe obesity.

Family-based treatment of children with severe obesity in a public healthcare setting: Results from a randomized controlled trial.

To compare the effectiveness of family-based behavioural social facilitation treatment (FBSFT) versus treatment as usual (TAU) in children with severe obesity. Parallel-design, nonblinded, randomized controlled trial conducted at a Norwegian obesity outpatient clinic. Children aged 6-18 years referred to the clinic between 2014 and 2018 were invited to participate.

The SED-GIH: A Single-Item Question for Assessment of Stationary Behavior-A Study of Concurrent and Convergent Validity.

The unfavorable health consequences of prolonged time spent sedentary (stationary) make accurate assessment in the general population important. However, for many existing questionnaires, validity for identifying stationary time has not been shown or has shown low validity. This study aimed to assess the concurrent and convergent validity of the GIH stationary single-item question (SED-GIH).

Categorical answer modes provide superior validity to open answers when asking for level of physical activity: A cross-sectional study.

Aims: Physical activity (PA) used as prevention and treatment of disease has created a need for effective tools for measuring patients' PA level. Our aim was therefore to assess the validity of two PA questions and their three associated answer modes.

Methods: Data on PA according to the PA questions and Actigraph GT3X+ accelerometers, aerobic fitness (VO(2)max), cardiovascular biomarkers, and self-rated general health were collected in 365 Swedish adults (21-66 years).

Effects of the Swedish physical activity on prescription model on health-related quality of life in overweight older adults: a randomised controlled trial.

Background: The effects of physical activity on prescription (PAP) on health-related quality of life (HRQoL) in overweight adults are unclear. We therefore aimed to explore the effects of the Swedish PAP model on HRQoL in overweight older adults.

Methods: Participants were recruited from a cohort of men and women born between 1937 and 1938, and living in Stockholm County.
