Since ancient times, the pursuit of health and longevity has never stopped. In ancient times, in order to pursue longevity, Emperor Qinshihuang sent Xu Fu to Penglai to ask for magic medicine; Emperor Taizong was addicted to pills; There are also many people who love eating jade. Even in the novel, there are also ginseng fruit, flat peach, and even “Tang Monk meat” and other foods that can make people live forever. Nowadays, with the development of science, human beings have more knowledge about life span and death. Although the secret of longevity has not been fully mastered, scientists have found that there is a simple secret to longevity – a healthy lifestyle.

Recently, a new study published in age and aging shows that a healthy lifestyle is related to a lower risk of death and a longer life expectancy. More importantly, this is true even among people over the age of 80 or with chronic diseases.

The new study comes from Japan, the country of longevity. The researchers analyzed data from the Japanese collaborative cohort study (JACC), which included 49021 participants. The average age of the participants was 56.8 years, and 43.7% were male.

The researchers counted the lifestyle information of participants in the previous year, including diet, physical activity, smoking status and alcohol consumption. Participants are considered healthy if their 8 lifestyles meet the following criteria:

Fruit ≥ 1 time / day, i.e. eating fruit at least once a day, or at least 7 times a week;

Fish ≥ 1 time / day, i.e. eating fish at least once a day, or at least 7 times a week;

Drink milk almost every day;

Exercise regularly, walk at least 0.5 hours a day, and exercise at least 5 hours a week;

Healthy body weight with body mass index (BMI) in the range of 21.0 kg/m2 – 25.0 kg/m2;

Do not smoke, never smoke or have quit smoking;

Do not drink alcohol, or drink a small amount of alcohol, alcohol intake ≤ 46.0 g/ day;

Healthy sleep, 5.5-7.4 hours of sleep per day.

In addition, the researchers also counted the education level, stress, and the history of cardiovascular disease, cancer, chronic kidney disease, hypertension, diabetes and other chronic diseases.

During an average follow-up of nearly 20 years, 9865 participants died, including 5824 men and 4041 women.

After excluding the influence of other factors, the researchers found that a healthy lifestyle is related to the reduction of the risk of death and the extension of life expectancy. The more healthy lifestyle, the greater the impact on death and life expectancy.

Among men, compared with participants with only 0-2 healthy lifestyles, participants with 3, 4, 5, 6 and 7-8 healthy lifestyles reduced the risk of death by 12%, 15%, 32%, 40% and 47% respectively.

Among women, compared with participants with only 0-2 healthy lifestyles, participants with 3, 4, 5, 6 and 7-8 healthy lifestyles reduced the risk of death by 3%, 26%, 33%, 38% and 44% respectively.

Healthy lifestyles are also associated with longer life expectancy. For example, at the age of 40, the remaining life expectancy of male and female participants with 7-8 healthy lifestyles was 46.5 years and 51.3 years respectively, which was 5.3 years and 6.2 years longer than that of males (41.2 years) and females (45.1 years) with only 0-2 healthy lifestyles.

The potential impact of healthy lifestyles on life expectancy continues to reach people aged 80 and over. Even at the age of 80, the remaining life expectancy of male (14 years) and female (14.3 years) participants with 7-8 healthy lifestyles was 4.4 years and 2.2 years longer than that of male (9.6 years) and female (12.1 years) participants with only 0-2 healthy lifestyles.

The results also show that even with chronic diseases such as cardiovascular disease, cancer, hypertension and diabetes, a healthy lifestyle will have an impact on life expectancy. The more healthy lifestyle, the longer the remaining life expectancy.

▲ among patients with chronic diseases of different genders, compared with participants with 0-2 healthy lifestyles, participants with 3-5 or ≥ 6 healthy lifestyles have the number of years that the remaining life expectancy has been extended. (data source: reference [1]; drawing: Wuxi apptec content team)

In addition, even with a variety of chronic diseases, the adoption of more healthy lifestyles will have a beneficial impact on life expectancy.

For example, at the age of 50, if participants with one, two and at least three chronic diseases have only 0-2 healthy lifestyles, their remaining life expectancy will be 34.3 years, 30.8 years and 25.3 years respectively, while participants with at least six healthy lifestyles will have their remaining life expectancy of 41.2 years, 39.2 years and 34.0 years respectively, and their life expectancy will be extended by 6.9 years, 8.3 years and 8.7 years respectively.

Finally, the study emphasized that life span depends on many factors, such as economic level, medical care, and lifestyle. Previous studies have found that a healthy lifestyle is associated with a lower risk of death and longer life expectancy. This study not only adds new evidence for this, but also highlights the continuing potential impact of healthy lifestyles, whether in people aged 80 or over, or in people with chronic diseases, on their life expectancy, and the more healthy lifestyles, the greater the benefits.

Since this study is an observational study, it only shows the impact of lifestyle on life expectancy, and does not show causality. Moreover, there are some limitations in the research, which may affect the research results. For example, a small amount of drinking is also considered as a healthy lifestyle, but many studies have found that even a small amount of drinking is harmful to health and increases the risk of cancer.

Hiroyasu ISO, the corresponding author of the study and professor of Osaka University in Japan, pointed out that more healthy lifestyles are directly related to the life expectancy of men and women. For people aged 40, the life expectancy has increased by more than 6 years.

“Even among the elderly (aged 80 or above) and people with one or more chronic diseases (including cancer, cardiovascular disease, hypertension, diabetes and kidney disease), this benefit is significant. At present, the prevalence of chronic diseases has increased globally and is the main cause of death among the elderly. Therefore, the findings of this study are expected to provide a way for patients with chronic diseases to prolong their life and bring more survival opportunities.” , Professor Hiroyasu ISO added.
