Hire Writer The second environmental factor which Dangles states on her essay is lack of physical activity Page
Three new studies, published in the April 8 Pediatrics, land on the import of the 'nurture' side of the equation and focus on specific circumstances in children's or teen's lives that potentially contribute to unhealthy bulk.
In three decades child and adolescent obesity has tripled in the U.
Obesity puts these kids at higher risk for type 2 diabetes, cardiovascular disease, sleep apnea, and bone or joint problems. The variables responsible are thought to range from too little exercise to too many soft drinks. Now it seems that blaming Pepsi or too little PE might neglect the bigger picture.
It's a natural consequence of normal kids with normal genes being raised in unhealthy, abnormal environments. But they are part of an even longer list: Size matters in "obesogenic environments" In one of the three new studies dishware size made a big difference.
Researchers studied 42 second-graders in which the children alternately used child-size Doubling the size of the dishware, the researchers found, increased the amount of food kids served themselves in a buffet-style lunch line by an average of 90 calories. They ate about 43 percent of those extra calories, on average.
Although kids can typically adjust their energy intake by regulating their food, Temple University public health professor Jennifer Fisher says, their surroundings and options may change that equation for kids in the same way that it does in adults. Although past research already had linked increased TV time to widening waistlines, this study dug deeper.
Ninety-one to year-olds filled out diaries for TV, video games and computer use during a one-week period.
About four to seven times a day the teens were paged to record what they were paying the most attention to at that particular moment, followed by activities receiving their second- and third-most attention.
His team's findings lent more support to the first two variables and less to the third. They found video games and computer use had no impact on BMI body mass index.
Television did, but only if it was the main event. Background TV, for example, didn't matter. In terms of unconscious eating, when you're watching TV, your hands are free and you're stimulating your senses with the TV, so concurrent eating is more likely to happen.
Freedhoff adds that even viewing commercials for fruits and vegetables has been shown to increase consumption of unhealthy foods.
Less physical activity is not the problem The screen-time study did find that kids engaged in more physical activity had lower BMIs, but that does not mean that more exercise is keeping those teens lighter, Freedhoff says. That's a crucial message that people don't understand—obesity is not a disease of inactivity.
Researchers tracked nearly 1, teenagers from ninth through 12th grade and found, like past studies, that less sleep translates to higher BMIs.The obesity epidemic is a global issue and shows no signs of abating, while the cause of this epidemic remains unclear.
Marketing practices of energy-dense foods and institutionally-driven declines in physical activity are the alleged perpetrators for the epidemic, despite a lack of solid evidence to demonstrate their causal role.
I strongly believe that environmental factors are the major factors which play a great role in obesity. As Dangles stated in her essay, easy access to fast food is one of the major environmental factors that contributes to obesity (Page Today, there are close to , fast food restaurants in United States.
Most obesity, however, probably results from complex interactions among multiple genes and environmental factors that remain poorly understood (multifactorial obesity).
Any explanation of the obesity epidemic has to consider both genetics and the environment. The author gives mainly two causes, environmental and gene factors. The other factor is the gene factor. In this essay, it is said that gene factors may also have an effect in causing people to be overweight and obese.
I strongly believe that environmental factors are the . Just as our lack of physical activity is a major contributor to the obesity epidemic, creating an activity-friendly environment is one way to help turn around the epidemic.
IOM workshop examines role of environmental exposures in obesity epidemic. (NTP), elaborated on the workshop’s goals. “We want to try to tease apart that interaction [between genetic factors and environmental exposures], and to reinforce the concept that obesity, with its attendant comorbidities such as diabetes and metabolic syndrome.
