For a long time, people have dreamed of living as long as possible, they are looking for what helps them, they have used several means, mythical and logical, such as medicine and appropriate food. This dream is closer to verification than before.
WASHINGTON (Reuters) – Body size, height and weight, as well as physical activity, have played a role in human life up to the age of 90, according to a new study.
The study found that women under age 90 were larger and less obese than women under age 70, but that men were more likely than women to benefit from physical activity.
The study was observational: only women were monitored and the cause was not identified.
"The results provide interesting insights into the fact that men's and women's health may respond differently to body mbad index, height, and exercise," said the epidemiologist. David from the University of Bristol, UK, who did not participate in the study. Fat based on the calculation of height and weight.
Long-term study
In 1986, researchers surveyed more than 7,000 Norwegian men and women aged 55 to 69 on their height, current weight and current weight at age 20.
They also asked about their current physical activity: walking alone or with dogs, horticulture, housekeeping, back and forth cycling or cycling, then sport for men and women based on their daily physical activity: less than 30 minutes, 30 to 60 minutes, 90 minutes or more.
The researchers found that 433 men and 994 women monitored lived up to the age of 90, taking into account other factors that affect longevity, such as current or past smoking and the level of alcohol consumption.
The results of the men and women participating in the study were very different, particularly with regard to the impact of height and physical activity.
The researchers found that women who said they had less weight at age 20 and weighed less as they grew older also lived longer than women who weighed more.
Size played a major role in the longevity of some women: the study found that women over 5 feet and 9 inches were more likely to live up to age 90 than women under the age of 5 feet and 3 inches.
The study found that height and weight were not considered an effective factor for men's survival up to the age of 90, while the activity Physical played a major role: the study found that physically active men 90 minutes a day were more likely to live up to the age of 90. 39% more than those who exercised less than 30 minutes a day and every 30 minutes of physical activity a day, men were more likely to reach the age of 90 years of 5%.
However, women who were physically active more than 60 minutes a day were more likely to experience physical activity up to 90 years of physical activity for 30 minutes a day. men, nothing rewarded increased physical activity. The study found that the optimal level of activity for women was 60 minutes a day.
Life expectancy slows down
Life expectancy is increasing in most of the world, but recent studies indicate a slowdown in some developed countries: in the United States, for example, life expectancy has declined in recent years.
According to the Center for Disease Control and Prevention, the use of excessive doses of drugs and suicide are declining, but the leading causes of death remain the same. It is heart disease, cancer and stroke, the three most deadly Americans, all due to weight gain and lack of exercise.
"It is now clear that obesity and sedentary lifestyles, devoid of any physical activity, are harmful to one's health," Karslick said.
He emphasized the importance of studies that rely on people who form groups.
