Recent research conducted over more than 20 years among more than 27,000 elderly people with an average age of 93 years in China suggests that Elderly population with body mass index (BMI) higher than normal. Linked to lower death rates and suggested that more prevention and attention should be taken to prevent the elderly from being too underweight
Normally, the BMI recommended by the World Health Organization as being within the normal range is 25. Beyond that is considered overweight. and more than 30 is considered obese. But this study has shown that the ideal weight and BMI for the aging population may need to be revised upwards.
“This paradox of obesity suggests that the optimal BMI tends to change with age. This may be slightly overweight or obese in older people,” the research team said in a report published in the journal Nature Aging, which listed the optimal BMI for this age group as 29.
Xiaoming Shi and his team studied this subject from 1998 to 2018. They found that the risk of death, particularly from cardiovascular disorders, decreased ‘when Increased BMI’ Even those with a BMI in the 30 to 35 range had a lower mortality rate than those with a BMI in the 20 to 25 range.
“One possible explanation for the inverse relationship of BMI and mortality is that Overweight and obesity may be indicators of improved nutritional status. And the benefits of good nutrition outweigh the harms of higher BMI,” the researchers said.
However, the research team noted that the study focused on Chinese people aged 80 and older and that the results were not applicable to other age groups and ethnicities, but many experts agreed BMI should be adjusted accordingly. go by age group
“More attention should be given to adequate nutritional support and the prevention of being overweight. Including maintaining a healthy weight and body composition in older people to promote good aging health,” the research team said in the report. as Jean Woo, Professor Emeritus of Medicine The Chinese University of Hong Kong said “Being slightly overweight or obese is generally good for older people’s health.”
