Study involving nearly 300 centenarians found key factors in longevity

A new study from the University of Otago in New Zealand has found some key factors in longevity: centenarians are common in active socializing and non-smoking throughout old age. Associate Professor Yoram Barak, of otago University, said: “Choosing not to smoke and working to maintain social networks will be the best investment in combating aging, and it shows that people can control the aging process to some extent.” “

Study involving nearly 300 centenarians found key factors in longevity

The study analyzed data on 292 centenarians without common chronic diseases such as diabetes, depression, dementia and high blood pressure, and included information on 103,377 other people over the age of 60, all of whom lived at home rather than in nursing homes.

The results showed that participants of all age groups were similarly involved in social activities of long-term interest. As we age, the incidence of depression and diabetes decreases steadily, and the incidence of dementia decreases after the age of 80. From the age of 60 to 100, the incidence of hypertension has decreased by nearly 30%.

There is evidence that exercise improves health and longevity, but in the study, most of the subjects had similar physical activity. Among those surveyed, those who exercised the most had the lowest risk of developing dementia.

In addition, the researchers found that centenarians were more likely to be women (75 percent) and that women were more likely to get rid of the common chronic diseases in any age group.

Because women have a longer life expectancy, they are more likely to participate in the 100-year study, the researchers said. After revising this advantage, men who live to 100 years of age are more likely to be less likely to develop these common chronic diseases.

Previous studies have shown that the number of cancer cases worldwide is expected to increase by 60 per cent by 2040, based solely on projected population growth and ageing, a number that could be significantly increased by unhealthy lifestyles. Smoking will be the number one risk factor for cancer, with about 2.3 million people worldwide dying from cancer in 2017, accounting for 24% of all cancer deaths.
