A combination of seven healthy lifestyle habits, including getting seven to nine hours of sleep every day, exercising and socializing regularly, lowers the risk of dementia in people with type 2 diabetes, according to a study. Neurology.

“Type 2 diabetes is a growing global epidemic, affecting one in 10 adults, and having diabetes is known to increase a person’s risk of developing mental illness,” said Yingli Lu of Shanghai Jiao Tong University School of Medicine in China. .

“We investigated whether a broad combination of healthy lifestyle habits could reduce that 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 people with diabetes who did not lead a healthy lifestyle.

For the study, researchers looked at healthcare databases in the United Kingdom and identified 167,946 people with and without diabetes at the start of the study. Participants completed health questionnaires, provided physical measurements and provided blood samples.

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

Habits include not currently smoking, moderate alcohol consumption of up to one drink per day for women and up to two servings per day for men, regular weekly exercise of at least 2.5 hours of moderate exercise or 75 minutes of vigorous exercise, and seven to nine hours of physical activity. Hours of sleep every day.

Another factor is a healthy diet, including lots of fruits, vegetables, whole grains and fish and less refined grains, processed and unprocessed meat.

The latter habits were sedentary, defined as watching less than four hours of television per day, and frequent social interaction, defined as living with others, gathering with friends or family at least once a month, and participating in social activities. At least once a week or more often.

Researchers follow participants for an average of 12 years. During that time, 4,351 people developed dementia. In total, 4% of people followed zero to two healthy habits, 11% three, 22% four, 30% five, 24% six and 9% 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 non-diabetics who followed all habits.

For people with diabetes who followed all practices, there were 21 dementias for 7,474 person-years or 0.28%. Person-years represent both the number of people in the study and the amount of time each person spends in the study.

For people with diabetes who followed only two or fewer practices, 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 of the habits were 54% less likely to forget than those who followed two or fewer.

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

“Our research shows that people with type 2 diabetes can significantly reduce the risk of dementia by leading a healthy lifestyle,” he said.

“Doctors and other medical professionals who treat people with diabetes should recommend lifestyle changes to their patients. Such changes not only improve overall health, but also contribute to the prevention or delay of dementia in people with diabetes.”

A limitation of the study is that people reported their lifestyle and may not remember all the details accurately. Lifestyle changes over time have not been captured as well.
