Abstract
The link between suicide and daily step counts was evaluated in all 47 prefectures of Japan by ecological study. The crude rate of suicide was significantly and negatively correlated with daily step counts. However, the association between the age-adjusted rate of suicide and daily step counts was noted only in men. These results suggest that increasing daily step counts may be useful for preventing suicide, especially in men, in Japan.
Highlights
Death due to suicide has become public health challenge in Japan as well as in the world [1]
We investigated the relationship between suicide and daily step counts in all 47 prefectures of Japan by ecological study
According to simple regression line, an increase in a thousand daily step counts corresponded to a reduction of 4 men and 6 womens’ death due to suicide in Japan
Summary
Death due to suicide has become public health challenge in Japan as well as in the world [1]. About thirty thousand people due to suicide have been reported in Japan for these ten years. There are many reports according to the cause of suicide i.e. health and socioeconomic factors [2]. Disability, which may induce less physical activity, is an important independent correlate of suicidal ideation [3]. The link between suicide and physical activity expressed as daily step counts has not been fully discussed. We investigated the relationship between suicide and daily step counts in all 47 prefectures of Japan by ecological study
