Some older people still believe that physical activity is unnecessary or even potentially harmful. Others recognise the benefits of physical activity, but report a range of barriers to physical activity participation. Strategies to enhance physical activity participation among older people should include (1) raising awareness of the benefits and minimise the perceived risks of physical activity and (2) improving the environmental and financial access to physical activity opportunities.

The limited evidence suggests patient-centred interaction styles related to the provision of emotional support and allowing patient involvement in the consultation process enhance the therapeutic alliance. Clinicians can use this evidence to adjust their interactions with patients to include communication strategies that strengthen the therapeutic alliance.

Objective: To investigate the effectiveness of active video games (AVGs) on obesity-related outcomes and physical activity levels in children and adolescents. Design: Systematic review with meta-analysis. Methods:Literature search was performed in five electronic databases and the main clinical trials registries. Randomized controlled trials investigating the effect of AVGs compared with no/minimal intervention on obesity-related outcomes (body mass index [BMI], body weight, body fat, and waist circumference) and physical activity levels of children and adolescents were eligible. Two independent reviewers extracted the data of each included study. PEDro scale was used to assess risk of bias and GRADE approach to evaluate overall quality of evidence. Pooled estimates were obtained using random effect models. Results: Twelve studies were considered eligible for this review. Included studies mostly reported outcome data at short-term (less or equal than three months) and intermediate-term follow-up (more than 3 months, but <12 months). AVGs were more effective than no/minimal intervention in reducing BMI/zBMI at short-term (SMD = −0.34; 95% CI: −0.62 to −0.05) and intermediate-term follow-up (SMD = −0.36; 95% CI: −0.01 to −0.71). In addition, AVGs were more effective in reducing body weight compared with no/minimal intervention at intermediate-term follow-up (SMD = −0.25; 95% CI: −0.46 to −0.04). Regarding physical activity levels, AVGs were not more effective compared with minimal intervention at short-term and intermediate-term follow-up. Conclusions: Our review identified that AVGs were better than minimal intervention in reducing BMI and body weight, but not for increasing physical activity in young people.
