November
is Diabetes Awareness month and the Centers for Disease Control and Prevention
has published its most recent findings on the prevalence of Diabetes Mellitus
in the United States. Currently it is
estimate that 25.8 million people (children and adults) suffer from diabetes here in
the United States. The number of
diagnosed cases of diabetes has increased in all fifty states from 1995 –
2010. More specifically, there was a 50%
or more increase in diabetes cases in 42 of 50 states during that 15-year span
with 18 states experiencing a 100% or more increase. Type 2 Diabetes has accounted for 90% – 95%
of the increase in diabetes cases in the United States. A further breakdown of the results can be
found HERE. If you would like specific data for your
state and/or county check out the CDC Diabetes
Interactive Atlases.
There
are three types of diabetes mellitus: type 1, type 2 and gestational.
For the purpose of this post I will focus on comparing type 1 and type 2 diabetes mellitus. The following table
highlights key information as available from the National
Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the
National Diabetes Information Clearinghouse.
|
Type 1
|
Type 2
|
Definition
|
The
body makes little to no insulin because the body destroys its own beta insulin cells
in the pancreas
|
The
body cannot utilize the insulin it produces because the insulin has become
dysfunctional and does not remove sugar (glucose) from the blood
|
Diagnosis/Factors
|
Autoimmune
condition; genetic and environmental factors could also play a role
|
Genetic,
obesity, physical inactivity, metabolic syndrome
|
Onset
|
Rapid
(within weeks)
|
Slow
(years)
|
Warning
signs
|
Increased
thirst and urination, weight loss, extreme tiredness, constant hunger
|
Feeling
tired or ill, frequent urination (especially at night), unusual thirst,
frequent infections, slow wound healing, weight loss
|
Affected
groups
|
Can
affect any age, but most cases diagnosed between 5 – 25 years
|
Traditionally
common in overweight, inactive adults, but as childhood obesity increases so
have the cases of type 2 diabetes in young people
|
Dependency
|
Insulin
dependent
|
Not
insulin dependent
|
Cure
|
None
|
Physical
exercise, healthy diet and weight loss
|
Treatment
|
Insulin
injections, diet modifications, regular physical activity; key is controlling
glucose levels
|
Diet,
exercise, weight loss, medication (some cased do require insulin injections)
|
TYPE 2
DIABETES AND YOUTH OBESITY
Currently
1 in 400 children and adolescent have been diagnosed with diabetes (type 1 and
type 2). Historically, it was more
common for youth and young adults to be diagnosed with type 1 diabetes and unlikely that they would be diagnosed with type 2, leading
to type 1 diabetes initially being referred to as juvenile diabetes. As the number of diabetes cases grows, cases
of type 2 diabetes in young people are increasing. Type 1 diabetes is still more prevalent,
but the rate of type 2 diabetes is increasing.
It appears that as rates of pediatric obesity increases, cases of type 2
diabetes increase. According to the 2011
Diabetes Fact Sheet:
- During 2002 – 2005 15,000 youth were diagnosed with type 1 annually and 3,600 youth were diagnosed with type 2 diabetes annually.
- Among youth aged <10 years, the rate of new cases was 19.7 per 100,000 each year for type 1 and 0.4 per 100,000 for type 2 diabetes. Among youth aged 10 years or older, the rate of new cases was 18.6 per 100,000 each year for type 1 and 8.5 per 100,000 for type 2 diabetes.
- Type 2 diabetes was extremely rare among youth aged < 10 years; while still infrequent, rates were greater among youth aged 10 – 19 years than in younger children.
- For youth aged 10 – 19 race influences the frequency of type 1 and type 2 diabetes; for non-Hispanic white youth the rate of new cases was higher for type 1 than for type 2 diabetes; for non-Hispanic black and Hispanic youth had similar rates for both type 1 and type 2 diabetes; for Asian/Pacific Islander and American Indian youth the rates were higher for type 2 than type 1 diabetes.
DIABETES
MELLITUS AND EXERCISE
It is
important to understand the role of exercise in the treatment of both type 1
and type 2 diabetes. Exercise can be a
key factor in maintaining a healthy lifestyle for anyone who has diabetes, but
understanding how exercise affects glucose and insulin levels is important to
maximizing the positive role of exercise in overall health and proper
management of diabetes.
For
athletes and others who are living with type 1 diabetes it is important to work
with their health care provider and/or diabetes educator to develop a treatment
plan specific to exercise. Understanding
how exercise specifically affects insulin and glucose levels will help
participants understand what sort of nutrition is required before, during and
after exercise. It also helps
participants understand what adjustments to insulin dosages are required before,
during and after exercise. Each person responds differently to exercise so the nutrition/insulin-exercise plan must be individualized. Recent
research shows that resistance and aerobic exercise improves
glucose control in those with type 1 diabetes. This means exercise can be an important key in managing type 1 diabetes consistently. Resources that can help give some basic
information on exercising with type 1 diabetes include the following:
For
those living with type 2 diabetes exercise is very important because it is a
key component of the overall treatment plan.
Exercise combined with a well managed diet is the best combination for those who need
to control their weight in an effort to manage (and potentially eliminate) type 2 diabetes. There has been increasing attention paid to
management of this condition as its prevalence continues to grow. For recommendations on safely exercising with
type 2 diabetes review the following resources:
As the
obesity epidemic continues to grow, so will the number of diagnosed diabetes
cases (particularly type 2). Exercise
plays an important role in decreasing the likelihood (or delaying onset) of
type 2 diabetes and improving the glucose response of those living with type 1
diabetes. It is important to take an
educated approach to exercise and management of diabetes. Living with diabetes doesn't keep you from
participating in your favorite sports; your favorite sport could help you
improve your overall health.
