Lack of parent willpower may contribute more to juvenile obesity than under-exercising or overeating.

 Research suggests that having overweight parents is a big, influence ( 影响) upon a child' s weight, with one study finding that child ren with overweight parents were four times more likely to be overweight themselves.

 The findings add heat to an already fierce political debate（争论）over childhood obesity. The Prime Minister, John Howard, last week decided that $116 million be Used for programs to deal with obesity, while the Opposition Leader, Mark Latham, recently announced that his party would move to protect children from unhealthy food advertisements

Clare Collins a senior lecturer at the University of Newcastle, believes such programs will definitely fail unless they influence the way of life of whole families. "If we can' t get parents to take action against their own weight problems, then we can' t expect to influence their kids," she said.

However, Professor, Louise Baur from the Children’ s Hospital at Westmead, doubts whether adult education programs offer any solution to weight problems. "Many parents know they need to lose weight and they know it influences their kids, but they lack the willpower to do anything about it.

The 10-year study of 150 American children found two-thirds of children with overweight parents became overweight. Only one in six children whose parents were of average weight became overweight.  

 The president of the Australasian Society for the .Study of Obesity, Associate Professor Gary Wittert, said parents needed help in doing their job and the Opposition Party’s policy（政策） might be on the right track.

 "We know that driving without a seat belt is unsafe, so we make law against it,” he said."Obesity is a major public health concern, so why shouldn’t we change the law regarding unhealthy food ads?"

Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.
In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (长寿). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.
