Media Use and Physical Activity Behaviour of Adolescent Participants in Obesity Therapy: Impact Analysis of Selected Socio-Demographic Factors

Cardiovascular endurance and psychosocial health predict short- and long-term BMI-SDS reduction: results from the CHILT III program

This longitudinal study analyzes data from the Children's Health Interventional Trial (CHILT) III, an 11-month juvenile multicomponent weight management program. The objective is to identify predictors of changes in body mass index standard deviation scores (BMI-SDS), so as to further enable the advancement of existing interventions with sustained impact. This study's sample consists of 237 children and adolescents with obesity (8-17 years, 54% girls) participating in the CHILT III program between 2003 and 2021. Anthropometrics, demographics, relative cardiovascular endurance (W/kg), and psychosocial health (i.e., physical self-concept and self-worth) were assessed at program entry ([Formula: see text]), end ([Formula: see text]), and one-year follow-up ([Formula: see text]; n = 83). From [Formula: see text] to [Formula: see text], the mean BMI-SDS was reduced by -0.16 ± 0.26 units (p < 0.001). Media use and cardiovascular endurance at baseline and improvements in endurance and self-worth over the course of the program predicted changes in BMI-SDS (adj. R² = 0.22, p < 0.001). From [Formula: see text] to [Formula: see text], mean BMI-SDS increased ([Formula: see text], p = 0.005). Changes in BMI-SDS from [Formula: see text] to [Formula: see text] were associated with parental education, improvements in cardiovascular endurance and physical self-concept, and BMI-SDS, media use, physical self-concept, and endurance level at program end (adj. R² = 0.39, p < 0.001).  Conclusions: This study highlights the need for comprehensive, sustainable weight management approaches, in order to sustain the initial treatment benefits. In this context, improvements in cardiovascular endurance and psychosocial health could be essential strategies to pursue in practice, as they significantly predicted reductions in BMI-SDS - both pre- to post-intervention and at follow-up.

WHAT IS KNOWN

• Childhood obesity is associated with the onset of noncommunicable diseases, many of which are likely to carry into adulthood. Thus, effective weight management strategies for affected children and their families are vital. However, achieving lasting positive health outcomes with multidisciplinary weight management programs remains challenging.

WHAT IS NEW

• According to this study, short- and longer-term BMI-SDS reductions are associated to cardiovascular endurance and psychosocial health. These factors should therefore be given even greater consideration in weight management strategies, as they may be important not only in themselves but also for long-term weight loss (maintenance).

Identifying drivers and factors affecting behavioral risk factors of noncommunicable diseases: A scoping review

BACKGROUND

A large proportion of noncommunicable diseases (NCDs) can be prevented by reducing unhealthy nutrition, inadequate physical activity, smoking, and alcohol consumption. The high burden of NCDs underlines the need for a greater understanding of the causes of these risk factors. This paper aims to identify factors affecting smoking, alcohol consumption, unhealthy nutrition, and inadequate physical activity in current and future times.

MATERIALS AND METHODS

A scoping review was conducted in Iran University of Medical Sciences, Tehran, Iran, in 2020 to identify factors affecting smoking, alcohol consumption, unhealthy nutrition, and inadequate physical activity. The review was guided by the five-step Arksey and O'Malley model. A deductive qualitative content analysis was employed to identify the factors synthesized through descriptive and narrative synthesis. The search was conducted in English without date restrictions up to January 2020.

RESULTS

We identified 1437 studies through database search and other sources and finally included 72 studies in the review. The content analysis of the data led to the identification of 27 factors affecting smoking, alcohol consumption, nutrition, and physical activity. The factors categorized into social, technological, environmental, economic, political, and values factors.

CONCLUSION

Political and economic factors have a significant effect on all risk factors, and it is necessary to take comprehensive measures to improve these factors. Technological factors have a greater impact on healthy nutrition. Physical activity is more affected by environmental factors than other risk factors. However, smoking and alcohol consumption are more influenced by social factors and individual attitudes.
