Global epidemic, preventing obesity epidemic is 2 1 century in the world.
One of the biggest health challenges facing China.
With the rapid development of economy and the continuous improvement of living standards in China.
The Improvement of Dietary Structure of Children and Adolescents and the Incidence of Obesity in China
Rising year by year. A study shows that obesity has been found among urban children and adolescents.
The rate is about 10%, and it reaches 20% in some big cities. To get to know me
In February 2003, the incidence of obesity among students in school was compared with that of first-year students.
The eighth-grade students made a health check-up survey and gave them a health check-up.
Analysis, the results are reported as follows:
1 survey object and method
1. 1 Object: Junior 1 students in our school *** 1262.
1.2 method
1.2. 1 measurement method
At present, there are many standards to evaluate obesity, mainly 1987.
China students' physical health research group published "China students' physical fitness"
According to the detailed rules of health research and testing and the internationally accepted body mass index [Jane
Weigh the body mass index, that is, weight (kg) divided by the square of height (m)] and so on.
No matter what standard is adopted, it should be based on the measurement of weight and height.
In quantity. Therefore, we are interested in the height and weight of all the interviewees.
After measurement, we finally adopted the "Study on Students' Physical Health in China".
Test rules "as a criterion for judging obesity, that is, the measured weight exceeds the same."
Obesity is 20% of the standard weight for the same height.
1.2.2 Cluster sampling questionnaire survey method
In order to understand the causes of obesity, according to the causes of obesity.
Some common factors, compiled the middle school students obesity questionnaire (table
1) and obesity knowledge questionnaire (Table 2).

3 analysis
3. 1 The occurrence of obesity is closely related to gender.
Table 3 shows that the incidence of obesity in boys is 14.6%, while that in girls is obese.
The incidence rate is 6. 1%, and the incidence rate of obesity in boys is much higher than that in girls. study sth in detail
The reason may be that boys appreciate strong and tall idols and pursue them.
Muscular, like to eat high-calorie food, coupled with lack of exercise,
So that the body accumulates too much fat, leading to a high incidence of obesity.
Girls, on the other hand, are influenced by social concepts and pursue slim figure and flatness.
Pay attention to diet control, so the incidence of obesity is relatively low.
3.2 Analysis of the main causes of obesity
3.2. 1 Unreasonable diet is the main cause of obesity.
One of the manifestations of unreasonable diet is excessive energy intake.
Food. Table 4 shows that the dietary structure of obese students is unreasonable.
Obesity accounts for 77%. The unreasonable dietary structure is mainly manifested in men and women.
Students like snacks (75%) and drinks with high sugar content.
(76%) and don't like drinking boiled water. Boys prefer eating meat.
Eating (7 1%), girls like sweets (72%). Explore its origin
Because, mainly since the reform and opening up, people's living standards have been continuously improved.
Many families have entered a well-off level. And now middle school students are definitely
Most of them are only children, and elders are always afraid that their children are not adequately nourished.
When it comes to nutrition, children will form a certain degree of partial eclipse and excess.
. 82 .
Eat it. From kindergarten to primary school and middle school, due to the pressure of further education, etc.
Children seldom take part in sports activities, thus forming food.
Most of them consume less, and too much energy is converted into fat to stay in the body and gradually disappear.
Become obese. The research results of American researchers also illustrate this point.
Point. Researchers at Boston University Children's Hospital spent two years.
Time, 548 children aged11-12 were investigated at MIT.
Children, knowing their eating habits, find that most of them don't.
Drink boiled water, milk or natural nutritious drinks, but prefer those with high sugar content.
Drinks (soft drinks), or juice drinks with sugar, and the amount of drinks.
There is an increasing trend, J. Children like to drink all kinds of sweet drinks more and more, but
Energy is the cause of childhood obesity. Experts pointed out that children
Children only need to drink one more can (bottle) of soda or sugary juice every day.
It is expected that these feeds contain enough sugar to make them obese.
Increase by 60%. During the period of 198 1 to 1994 in the United States, obese children
Children have doubled, and 24% of them are obese, which may be
It has something to do with American children's special preference for sweet drinks.
The second manifestation of unreasonable diet is unreasonable eating habits. table
4 shows that quite a few students don't often eat breakfast and binge drink.
The habit of eating fast food. According to the Chinese Academy of Preventive Medicine Camp
The results of spot checks published by the Institute of Nutrition and Food Hygiene show that: early
The frequency of eating is inversely proportional to the obesity rate of children. Eat 0 to 1 every week.
The obesity rate of the second breakfast group was 18.6%, and it was eaten 2 ~ 4 times a week.
The obesity rate in the meal group was 13.5%, and the breakfast group ate it 5 ~ 7 times a week.
The obesity rate is 1 1.8%, and children who often skip breakfast are obese.
The risk of obesity in children who eat breakfast regularly is about 1.7 times. guzzle
Eating fast, it is easy to lead to satiety without timely feedback to satiety.
Food centers can't inhibit eating, thus increasing food intake.
Number of people. Lead to obesity.
3.2.2 Lack of physical exercise is an important cause of obesity.
Weipu information
Zhu: Investigation and analysis of obesity among middle school students
Table 4 shows that lack of physical exercise is an important cause of obesity.
Because. At present, the study pressure and academic tasks of middle school students in China are far from each other.
Compared with western countries, middle school students spend most of their time in class.
At the dinner table, and the rare rest time is spent watching TV and playing games,
Lack of adequate physical exercise. China preventive medicine nutrition and nutrition society
The results of a spot check published by the Institute of Food Hygiene show that children's fat
The obesity rate increases with the increase of TV watching time, with an average TV watching time.
With every increase of 65438 0 hours, the incidence of obesity increased by 65438 0.5%. Researcher integral
When analyzing this problem, it is said that sports activities are replaced by watching TV, which leads to
One of the important factors of childhood obesity today. According to the survey, China
The number of TV sets owned by urban residents per 100 households ranges from 1985.
17.2 1, increased to11.57 in 0999, and I have already watched TV.
At present, it has become the main way of after-school entertainment for children and adolescents. survey
The survey shows that people watch TV for less than 1 hour, 1 to 2 hours, 2 to.
For children and adolescents aged 3 hours or more, the obesity rate is
10.9% 、 1 1.8% 、 13.2% 、 15. 1% 。 Besides, playing for a long time.
Game consoles are also a risk factor for the increase in childhood obesity.
3.2.3 Social concept and environmental influence are also important factors leading to obesity.
Superficial cause
Besides genetic factors and environmental factors, social and cultural factors are also right for children.
The influence of childhood obesity cannot be ignored. Table 4 shows that many students are interested in
Obesity is not fully recognized, and it is not realized that obesity is a non-obesity.
Healthy performance. In addition, in the traditional culture of China, fat means "happiness".
Gas "and" health ",many people think chubby children are cute and healthy.
Kang. Studies show that children and their parents want boys.
It is best to be fat and strong, and those parents who like fat children
Children are also prone to overweight.
3.3 Obesity knowledge awareness rate is low
Table 5 shows that the students surveyed have a good understanding of the concept, causes and risks of obesity.
The correct answers to the knowledge of hazards and preventive measures are 25% and 19 respectively.
3%, 2 1%, 12.9%. Many students think that obesity is not.
What disease has little effect on health.
4 countermeasures
Obesity not only affects the health of teenagers, but also directly affects people.
Life expectancy will also make people feel inferior and affect the psychology of teenagers.
Healthy. The formation of adolescent obesity is the result of many factors.
If only a single method is used in the treatment process, the effect will be ignored.
It is believed that some experts at home and abroad have used simple diet control or simple
Exercise training is not effective in treating obese children. Therefore;
It needs the attention of the state, society, schools and families to prevent it.
Control the incidence of obesity. first
Do a good job in obesity prevention. Once obesity occurs, it is very difficult to lose weight.
Difficulties, the best measure is prevention. The government and schools should vigorously advocate
Guide a healthy lifestyle, comprehensively promote prevention programs, and attach importance to parents and learning.
Health education, improve the health knowledge literacy of the whole society, in order to prevent teenagers.
Adolescent obesity has created favorable conditions. Second, take an integrated approach.
Treatment. At present, it is recognized at home and abroad as suitable for the treatment of adolescent obesity.
It is a comprehensive treatment including behavior correction, diet adjustment and exercise.
