Physical
inactivity is a powerful risk factor for obesity. Thus the promotion of
physical activity is an integral part of the fight against this disease. A new
study, although people additional demonstrates that regardless of sport and
dietary imbalances, time spent watching TV is directly associated with obesity
and overweight.
In
industrialized countries, the epidemic of obesity is soaring, both in adults
than in children. Or overweight and childhood obesity persist into adulthood
and are accompanied by many serious complications. Since 1999, the Ministries
of Education, Health undertook several surveys on the health of children in
schools. One, conducted in Kindergarten for the 1999-2000 school year,
estimated the prevalence of overweight and obesity at 14% in children aged 5-6
years. More recently, in 2001-2002, the prevalence was estimated at 20% among
10-11 year class CM2.To the establishment of targeted actions of prevention and
education, school doctors of the department Peter Edward embarked on a new
study in September 2003 with students enrolled in 6th in public colleges (11-12
years). A total of forty classes were selected in sixteen overweight institutions.
The each participant was defined by calculating the body mass index (BMI),
based on size and weight. Meanwhile, the children answered a questionnaire
about their eating habits (number and composition of meals, snacks, soft drinks
??) and lifestyle (leisure, sport, outdoor games, etc.). Physical inactivity
was estimated from the daily frequency of time spent watching television or
playing a video game.
The
analysis of these data shows that 15.7% of college students were overweight, of
which 13.6% in moderately overweight and 2.1% obese. 83% of students, the value
of BMI when they were younger was known: at the age of 5-6 years, 12.1% of
these students were overweight, including 9.7% in moderately overweight and
2.4% obese. The prevalence of overweight was so pronounced in recent years and
many overweight children 5-6 years old, are still at 11-12 years.
The
authors find no association between overweight and the consumption of sweets
and sugary drinks, outdoor gaming habits and the weekly frequency of playing
sports outside school. In contrast, overweight is more often present in
children usually watching TV at night school days and afternoon rest days.
"The fact of watching TV or playing video games more than twice a day
during the days school was significantly associated with overweight. »
The
conclusion draws itself. To protect children from obesity:
no
TV or video games more than once a day (or even only on Wednesdays and
weekends)
balanced
and varied diet, no snacks or sugary drinks, while the taste is essential
after-school
sports.
The
conclusion draws itself. To protect children from obesity:
