Comparing the differences in three measures of healthy life expectancy among prefectures in Japan

Factors affecting subjective health of child-rearing-aged Japanese adults, considering the effect of healthy life expectancy: A cross-sectional study

Objectives:

The extension of healthy life expectancy is an important policy issue in Japan. This study aimed to clarify the association between subjective health and healthy life expectancy and identify the factors that improve subjective health of child-rearing-aged adults in Japan.

Methods:

A cross-sectional study was conducted. We used data from 2718 participants of the Japanese General Social Survey 2009 Life Course Study. The mean age was 35.5 ± 4.10 years, and 56% were female. Multivariate logistic regression analysis was performed on subjective health, which was treated as a binary variable when calculating healthy life expectancy as an objective variable. The predictors were gender, age, marital status, number of family members living in the home, household income, mental health score, age of youngest child, and the person from whom one seeks help. The prefecture where the participants resided was treated as a control variable.

Results:

There was no association between individual subjective health and healthy life expectancy. Mental health score (measured by the Mental Health Inventory-5, MHI-5) was significantly associated with subjective health. With a MHI-5 score of ⩽ 10 points as the reference criterion, as the score increased, the odds ratio of subjective health increased, and for MHI-5 scores ⩾ 16 points, odds ratio was 14.14 (confidence interval: 7.57–26.38).

Conclusion:

Among the child-rearing-aged adults, prefectural healthy life expectancy was not associated with individual subjective health. Mental health was significantly associated with subjective health and may be underestimated in calculating healthy life expectancy.

[Effect of Iki-Iki Hyakusai Taiso on the prevention of progression of frailty in Nose Town, Osaka Prefecture]

AIM

We examined the effect of "IkiIki Hyakusai Taiso" as way to prevent the physical decline in community-dwelling elderly in Nose Town, Osaka Prefecture.

METHODS

Participants were community-dwelling elderly who participated in the Preventive Care program "IkiIki Hyakusai Taiso" from October 2015 to June 2019 in Nose Town, Osaka Prefecture, Japan. They performed exercises once a week. An assessment of the physical function, basic health checklist, and questionnaire about daily life were collected. Frailty was determined based on responses to the basic health checklist.

RESULTS

A total of 1,028 community-dwelling elderly people participated in this project. There were 766 (74.5%) women. The mean age of the participants was 72.6±8.0 years old, and 506 participants (49.2%) were part of the young-old generation. The physical function measurement values, including the 5-meter walking speed, time up and go test (TUG), 5 times sit to stand, and grip strength all significantly improved. Ninety percent of the participants participated in this program every time it was held. Regarding the self-rated health questionnaire, the rate of "feeling good due to participating in the program" increased from 29.1% to 45.4% after participating in this program for 6 months. The prevalence of partial social activities was mostly an increasing trend among the participants of this program.

CONCLUSION

Our findings showed that "IkiIki Hyakusai Taiso" improves and maintains the physical function and self-rated health among community-dwelling elderly individuals. Therefore, "IkiIki Hyakusai Taiso" seems to be a very useful preventive care program in the community.
