There’s been a lot of research on obesity. The first thing people need to
know about obesity is that it is defined differently than overweight.
Obesity means having too much body fat, while being overweight
means weighing too much. Both mean that a person's weight is greater than
what is considered healthy for his or her height.
Since kids grow at different rates, it isn't always easy to know when a
child is obese or overweight. That’s why it’s so important to ask your doctor
to measure your child's height and weight to determine if they are in a healthy
range.
With that in mind, let’s look at the research on obesity. Approximately 9
million American children over the age of 6 are already considered obese.
That’s a lot. So we need to be focusing A LOT more on prevention of this
problem.
So, what does successful childhood obesity prevention
require?
Making changes at multiple levels of society, starting with families.
Parents have to understand this issue and then take action. Individual
communities can also do more. Interventions must provide support to
individuals, families, schools, health care providers, and communities in
making changes that will lead to healthier eating and more fitness among
adolescents.
Let’s look at some more research on obesity.
A British study, involving 5,500 children and published in the latest issue
of PLoS Medicine, used accurate methods to measure the ‘fat mass’ of the
kids and the amount of physical activity they were involved in. The
researchers concluded that low levels of activity, particularly moderate and
vigorous activity, play an important role in the development of obesity.
While it would appear to be common sense that anyone who is
overweight or obese has been doing less physical activity than others, body
fat and energy output are hard to measure accurately.
The researchers employed advanced techniques – an Actigraph
accelerometer for activity and an X-ray emission absorptiometry scanner for
fat mass. They considered that the top 10% of the children in terms of fat
mass were obese.
What those techniques showed was that the less a child is active, the
higher their fat mass will be. This effect was stronger in boys than in girls.
What is abundantly clear in this research, though, is that greater activity,
especially moderate and vigorous activity, should be a key part of policies to
address the obesity epidemic.
So, what is some of this moderate or vigorous activity?
Parents, it’s up to you to take charge if your child doesn’t volunteer to
do any of these things. Tell them you’re going to sign them up for a sport or
activity, and give them a list. Then, let them choose. Only choose for them if
they refuse. Then follow through. Encourage. And think about setting a good
example. What physical activity can you do with them? If they see you active
and interested in being fit, then they’ll be more motivated to participate as well.
