Average life expectancy and healthy life expectancy in Yokohama City

Healthy life expectancy was calculated based on the population and the number of deaths based on the data for Yokohama City in the Basic Survey on National Life conducted by the Ministry of Health, Labour and Welfare every three years.
Looking at the changes in healthy life expectancy and average life expectancy (Table 1), the healthy life expectancy in 2010 (the period during which daily life can be restricted due to health problems) is 70.98 for men and women 75.65 years. Compared to the whole country, both men and women are higher than the national value (male: 70.42, female: 73.62).

The difference between the average life expectancy and healthy life expectancy in 2010 (the period during which daily life is restricted) (Table 2) is 9.44 for men and 11.33 for women.

In future health measures, it is important not only to extend the life expectancy but also to extend the healthy life expectancy.
The challenge is how to reduce the difference between average life expectancy and healthy life expectancy.

We found that women were 1.89 (11.33-9.44) years longer than men.

In 2010, the period during which daily life is restricted for those aged 65 and over (Table 3) was 5.46 years for men aged 65 and 7.56 years for women, about 1.4 times longer than for men, 85 years for men and 4.73 years for women, about 1.6 times that for men.

Comparing healthy life expectancy in 2004 and 22 years (Table 4), men increased by 1.32 years from 69.66 to 70.98, and women increased by 4.48 years from 71.17 to 75.65.

The average life expectancy at the same time was increased by 1.16 years for men and 1.45 years for women, and the increase in healthy life expectancy was greater than the increase in average life expectancy.
