Study uncovers new insight for improving the diabetes risk profile in
MONTRÉAL, Oct. 19, 2013 /CNW/ - Long considered an adult-only disease,
type 2 diabetes is becoming more prevalent among children. Children as
young as eight years of age are being diagnosed with type 2 diabetes
and the incidence appears to be increasing rapidly. The development of
type 2 diabetes is closely related to obesity; however other risk
factors include family history, ethnic background, and physical
Dr. Jonathan McGavock, a Canadian Diabetes Association past scholar and
research scientist at the Manitoba Institute of Child Health, along
with his colleagues, will present an oral abstract on Physical Activity Intensity and Adiposity in Obese Youth: The P.O.W.E.R
Trial on Sat., Oct. 19 at the 16th annual Canadian Diabetes Association and Canadian Society of
Endocrinology and Metabolism Professional Conference and Annual
Meetings in Montréal.
The P.O.W.E.R. Trial identifies the effects of vigorous versus moderate intensity exercise
training on obese youth and their risk of developing type 2 diabetes.
This trial was conducted to better understand what type of physical
activity will help prevent obese children from developing type 2
"Physical activity plays a powerful role in the prevention and
management of type 2 diabetes, however, little data exists to describe
the role of physical activity in the prevention of type 2 diabetes in
obese youth," says Dr. Jonathan McGavock. "Since health care
expenditures associated with diabetes are significant, novel cost
effective strategies are required to prevent early-onset type 2
diabetes and its complications in youth."
Obese youth ages 13 to 19 years old were recruited for the P.O.W.E.R Trial. The 120 selected youth were randomly placed into three groups: a
vigorous physical activity group, a moderate physical activity group
and a sedentary control group. Over a period of six months, physical
activity programming was delivered three times weekly for 30 to 45
minutes to both the vigorous and moderate physical activity groups.
Visceral adipose tissue (fat tissue around internal organs in the
abdominal cavity), liver fat content, total body fat and waist
circumference were measured.
The study concluded that increased physical activity, regardless of
intensity, leads to fat reduction in obese youth. Vigorous physical
activity was not associated with greater loss of fat tissue relative to
moderate physical activity, despite the original hypothesis stating
that vigorous intensity physical activity would lead to a greater
reduction in fat tissue.
"These findings are important as they indicate any level of physical
activity will reduce the long-term effect of metabolic syndrome and
type 2 diabetes in obese youth," says Dr. McGavock. "The future goal
for my work is to create much-needed objective evidence to inform
public policy and clinical decision making for the role of physical
activity in the prevention of type 2 diabetes in youth."
The Canadian Diabetes Association's evidence-based 2013 Clinical Practice Guidelines for the Prevention and Management of
Diabetes in Canada (Guidelines) recommend anticipatory guidance promoting healthy eating, maintenance
of a healthy weight and regular physical activity as part of routine
pediatric care. The Guidelines also state regular targeted screening for type 2 diabetes in children
at risk. It is also recommended children with type 2 diabetes receive
care in consultation with an interdisciplinary pediatric diabetes
health care team. Early screening, intervention and optimization of
glycemic control are essential, as the onset of type 2 diabetes during
childhood is associated with severe and early onset of microvascular
complications. New to the Guidelines this year are recommendations that suggest people with diabetes should
set specific physical activity goals. In addition, structured exercise
programs supervised by qualified trainers should be implemented, when
possible, for people with type 2 diabetes in order to improve glycemic
The P.O.W.E.R Trial was funded by the Lawson Foundation, the Cosmopolitan Foundation, the
Canadian Diabetes Association and the Canadian Institutes of Health
