And 60 minutes of daily physical activity is associated with the best chance of reaching 90 for women – ScienceDaily



The height and weight of the body can affect women's lives much more than men, suggests the study, published online at Journal of Epidemiology & Community Health . And while physical activity is associated with a longer life of both sexes, it seems that the more time men spend physically active each day, the better their chances of reaching old age, while 60 minutes a day are associated with the least- the best chance for women. Average life expectancy has risen over the last few decades, but has recently begun to plummet in some developed countries, with increasing levels of obesity and physical inactivity that are believed to be behind this trend. Previous studies looked at the relationships between weight (BMI or body mass index), physical activity and old age, but most studies have combined both sexes or focused exclusively on men.

Life of Women and Men Different That May Be Affected

To investigate these differences further, the researchers analyzed data from the Dutch Cohort Study (NLCS), which includes more than 1

20,000 men and women aged between the ages of 55 and 69 when they wanted to see if there was any connection between height, weight, leisure time, physical activity and the likelihood of reaching 90 years of age, and if there were any differences between men and women.

About 7807 participants (3646 men and 4161 women aged 68-70) provided detailed information in 1986 about their current weight, height, weight when they were 20 years old and their physical activity in the free its time

This includes activities such as gardening, walking, doing homework, walking or cycling to work, and recreational sports that have been grouped into daily allowance categories: less than 30 minutes; 30 to 60 minutes; Participants were then observed to death or 90 years of age, whichever comes first.

Researchers considered potentially influential factors such as whether current or former smokers are involved, how much they have drunk About 433 men (16.7%) and 944 women (34.4%) have survived to 90 years of age.

Women who are still alive up to this age are on average higher, weighed less at the start of the study, and at 20 years of age they were losing weight than those who were shorter and heavier .

Moreover, women who were more than 175 cm (5 feet 9 inches) in height were 31% more likely to reach 90 than women less than 160 cm

In men no such associations have been observed. more than 90 minutes a day are 39% more likely to reach 90 than those who are less. And every 30 minutes of daily physical activity that they have accumulated was associated with a 5% increase in their chances to get 90.

But that was not the case with women. Those who have spent more than 30-60 minutes a day are 21% more likely to reach 90 than those who manage 30 minutes or less.

But there seems to be an optimal threshold for women: about 60 minutes a day are associated with the greatest chance of celebrating their 90th birthday

This is a monitoring study and therefore can not establish a cause. Information about body size and physical activity was more voluntary than measured objectively, which may affect the results, researchers say.

But the findings are based on a large number of people, all of whom are similar in age, which strengthens the results, they point out, adding that their study is one of the few to distinguish lifestyle factors associated with long life between men and women.

There may be no connection between body size and old age for men. , said the researchers. But the history of behavior and illness seemed to affect open associations and there were differences between smokers and non-smokers
