American life affects life expectancy.

According to Sing Tao Daily, The New York Times reported that many people live in the United States in pursuit of a better life, but they may not have expected that their life expectancy will be shortened after going to the United States. Many studies have found that the longer immigrants live in the United States, the more likely they are to suffer from heart disease, high blood pressure and diabetes. Their next generation born in the United States is less healthy than their parents, and their life expectancy is lower. Many studies have confirmed the above conclusion, but experts are still determining the reasons behind it, and the current direction is mainly focused on living habits.

Professor Valdez of the University of New Mexico described that the traditional diet of immigrants generally contains a lot of fiber and less meat, which is a healthy menu recommended by doctors, while the food in the United States is large and high in calories. The cost of immigrants' integration into the United States in taste is the sacrifice of health.

Some immigrants explained that there are many factors involved. First of all, in many people's minds, a large appetite is a symbol of wealth, and eating fast food is equivalent to eating out, which can also prove their economic improvement; Others feel hard, at least to satisfy their appetite; Especially for low-skilled immigrants, working hours are generally long, and fast food has become the first choice for themselves and their children.

Besides, many immigrants try to avoid being regarded as? Aliens? Or avoid the troubles caused by identity, try to avoid walking, hiking and other sports, making your obesity and diabetes increasingly serious.

To make matters worse, although the children of immigrants born in the United States may be relatively rich economically, their health status and average life expectancy are not as good as those of the previous generation. It is not excluded that Americans' habits such as smoking, drinking, high-calorie diet and lack of exercise offset the positive factors of the relatively perfect medical system and high per capita income in the United States.

After sorting out the national data from 2007 to 2009, the National Health Data Center found that the average life expectancy of the first generation of Hispanic immigrants in the United States was 2.9 years longer than that of Hispanics born in the United States. A study conducted by the University of California, San Francisco and the Ministry of Health also found that the first generation of immigrants are at least 20% less likely to die of cancer than their American-born compatriots. The probability of death from heart disease is low16%; The probability of kidney disease is low18%; The risk of cirrhosis is 24% lower.

In addition to diet, alcohol and tobacco, experts do not rule out the influence of the family environment. Hispanic immigrants born in foreign countries have a higher proportion of families living together. On the other hand, Hispanic immigrants born in foreign countries have a high proportion of single-parent families, and it is difficult for family members to take care of each other. If life is hard, their health and longevity will naturally be affected.

However, the researchers said that although the life expectancy of immigrants has been shortened in the short term because of American living habits, it does not rule out that their life expectancy will increase in the long term after the economy improves.
