According to a study published in Neurology.

“Type 2 diabetes is a global epidemic affecting one in 10 adults, and diabetes is known to increase the risk of developing dementia,” said study author Yingli Lu, MD, PhD, of the Shanghai Jiao Tong University School of Medicine in China. .

“We investigated whether a broad combination of healthy lifestyle habits could offset this risk of dementia and found that people with diabetes who incorporated seven healthy lifestyle habits into their lives had a lower risk of dementia than those with diabetes. people with diabetes who were not leading a healthy lifestyle.”

For the study, researchers looked at a UK healthcare database and identified 167,946 people aged 60 or over with and without diabetes who did not have dementia at the start of the study. Participants completed health questionnaires, provided physical measurements and donated blood samples.

For each participant, the researchers calculated a healthy lifestyle score from zero to seven, with one point for each of the seven healthy habits.

Habits included no current smoking, moderate alcohol consumption of up to one drink per day for women and up to two per day for men, regular weekly physical activity of at least 2.5 hours of moderate exercise or 75 minutes of vigorous exercise, and seven to nine hours of sleep per day.

Another factor was a healthy diet including more fruits, vegetables, whole grains and fish and less refined grains, processed and unprocessed meats.

The last habits were least sedentary, defined as watching television less than four hours a day, and frequent social contact, defined as living with others, getting together with friends or family at least once a month, and participating in social activities at least once a week or more often.

The researchers followed the participants for an average of 12 years. During this period, 4,351 people developed dementia. In total, 4% of people followed only zero to two of the healthy habits, 11% followed three, 22% followed four, 30% followed five, 24% followed six and 9% followed the seven.

People with diabetes who followed two or fewer of the seven healthy habits were four times more likely to develop dementia than people without diabetes who followed all seven healthy habits. People with diabetes who followed all habits were 74% more likely to develop dementia than those without diabetes who followed all habits.

For people with diabetes who followed all the habits, there were 21 cases of dementia per 7,474 person-years or 0.28%. Person-years represent both the number of people participating in the study and the time each person spends on the study.

For people with diabetes who followed only two or fewer habits, there were 72 cases of dementia per 10,380 person-years or 0.69%. After adjusting for factors such as age, education and ethnicity, people who followed all the habits had a 54% lower risk of dementia than those who followed two or fewer.

Each additional healthy habit people followed was associated with an 11% lower risk of dementia. The association between healthy lifestyle score and dementia risk was not affected by the medications people took or how well they controlled their blood sugar.

“Our research shows that for people with type 2 diabetes, the risk of dementia can be significantly reduced by adopting a healthier lifestyle,” Lu said.

“Physicians and other healthcare professionals who treat people with diabetes should consider recommending lifestyle changes to their patients. Such changes can not only improve overall health, but also contribute to the prevention or delayed onset of dementia in people with diabetes.

A limitation of the study was that people reported their lifestyle habits and may not remember all the details accurately. Lifestyle changes over time were also not captured.
