Obesity has many edges, pharm but basically boils down to a basic financial statement: if they enter the body more calories than are expended, ambulance will gain weight. It's that simple… and, cialis 40mg sometimes, difficult to balance.

It follows, course, if what is sought is to prevent childhood obesity, is not only important to improve the diet of children (and therefore reduce the excess calories), but also increase energy expenditure by stimulating physical activity.

“What the kids eat, How are your eating patterns, major deviations, deficit or excess consumption are up to this pretty well known-they said the lawyer Sergio Britos, researcher at the Center for the Study of Child Nutrition (Cesni)-. However, few studies that have attracted attention to the other side of the equation, caloric expenditure.”

As an attempt to address this deficit, Cesni decided to face the first oriented accurately measure the movement and physical activity that children develop and translate to study energy expenditure.

Specialists worked on a sample of 312 schoolchildren 11 years on average, eight schools in the city and the areas north and western suburbs.

As food, results corroborated the obesity figures already known: the 26% of the boys were overweight and 7%, obesity. “The children who attend public schools in double shifts and lunch at school were more thick-explains-Britos, which again put on the table the issue of the quality of the food served in school cafeterias.”

To make accurate records not only of the intended activity, but primarily spontaneous, researchers designed a protocol to measure what kind of physical activity do and how intensely. They use a device the size of a cell-called triaxial accelerometer- electronically measuring the movements in three dimensions: horizontal, vertical y lateral. For three or four days each recorded minute by minute movement made, and translated into the equivalent in calories (caloric expenditure) with specific software.

“Allow accurately record what children do during the day, at home or at school, weekdays and weekends, says Britos-. We offer a fine x-motion.”

The analysis of the records obtained by the accelerometers indicated that 35% guys spend more than three hours in front of TV screens and PC, percentage rises to 60% during weekends. A 17% boys (more girls than boys) do not cover the recommendation for 60 daily minutes of moderate-intensity movements and. “It is the core of the sedentary”, says Britos.

The problem is complex because of where you look. With narrow houses, lack of time or both to accompany, deposited parents hope that their children “move” school… no luck. “While some international recommendations suggest that the school should contribute to the 50% Daily time spent on activities rather than moderate intensity, in our study was lower than that percentage 20% -states-. It turned unpleasantly surprising to find that the classes of physical activity are of low quality and only spend a third of their time to activities of moderate intensity and more.”

The breaks do not help much, because in them the guys move way more than moderate the same proportion of time (a third). “Good to know that meant a longer recess 10% over activities that require more caloric expenditure”, says specialist.

In studying Cesni, the guys who showed better indicators of body fat mass and were those who made more than 90 daily minutes of intense movement.

“Clearly recommending 60 daily minutes of moderate activity and insufficient as a preventive factor in obesity-warns-Britos. Necessarily breaks should be more active and physical education classes, increase the quantity and improve motion intensity. A 10% and sometimes more caloric expenditure comes from the spontaneous movement. No action is required of the big boys athletes or enroll them in high performance sport. Just use the available spaces (such as grocery shopping or walking pets) to move more.”


“As a country, Argentina weighs the 200 million kilos more than I should.” To resolve this problem of proportions, he illustrates licensed Britos with mathematical precision, from the results of this study, which also intervened nutritionist Beatriz Gripo, and is now present in the complex La Plaza, in International conference on nutrition and physical activity ( ) , Cesni specialists plan targeted interventions to promote better use of recess. “There are two alternatives: or longer or more intensely ?says Britos?. Not just isolated interventions, political decisions are needed for the child population will go.”
