Abstract
Global rates of type 2 diabetes (T2D) among children and adolescents are steadily rising. As such, an increasing amount of attention and research has begun to focus on strategies to prevent this chronic and burdensome disease in pediatric populations. The purpose of this article is to briefly review current evidence pertaining to the effectiveness of physical activity versus metformin in improving insulin sensitivity of children at-risk (ie, obese and/or insulin resistant) for developing T2D. Potential barriers to each preventative intervention will also be discussed. Physical activity, both aerobic and resistance, has demonstrated effectiveness in a moderate number of demographically diverse pediatric studies. However, the pediatric population is already alarmingly sedentary with barriers such as lack of motivation, social stigma and discomfort presenting a challenge. A small number of studies have demonstrated the beneficial effects of metformin in children and adolescents for improved insulin sensitivity. However, longer and larger studies are required to confirm these findings and elucidate upon the long-term safety and efficacy of this pharmaceutical in pediatric populations. While no head-to-head studies examining physical activity and metformin exist in pediatric populations and more research is needed, current evidence seems to favour the use of physical activity given the larger quantity of studies and generalizability of its beneficial effects. Thus, physical activity should be emphasized in clinical and public health practice when targeting at-risk children and adolescents to prevent a T2D diagnosis.
Highlights
Global rates of type 2 diabetes (T2D) among children and adolescents are steadily rising
Given the alterable nature of these factors, clinical practice guidelines from the Canadian Diabetes Association assert that early screening and intervention in children and adolescents at-risk for T2D is essential.[2]
The purpose of this article is to briefly review current evidence pertaining to physical activity versus the use of metformin for improving insulin sensitivity in children that are at-risk for developing T2D
Summary
Global rates of type 2 diabetes (T2D) among children and adolescents are steadily rising.
