Résumé
Improving sleep quality is important for an aging society. However, no study has been conducted on the association between dietary variety and sleep efficiency among older Japanese adults using longitudinal data. The current study is a longitudinal study that aimed to elucidate the association between dietary variety and sleep efficiency in older Japanese adults. This study was conducted among older adults (≥70 years old in 2016) in the metropolitan area of Tokyo, Japan, between 2016 and 2018. Dietary variety score (DVS) and sleep efficiency were determined for all participants and were used to assess dietary habits and sleep quality, respectively. A cross-lagged panel analysis was used to consider the prospective associations between DVS and sleep efficiency, and this analysis was performed before and after adjusting for possible covariates in the 2016 data. After adjusting for age, sex, body mass index, current drinking status, current smoking status, exercise habits, living (alone or with others) style, the Japanese version of the Geriatric Depression Scale (Short Form), sleep duration and retiring time the DVS in 2016 predicted the sleep efficiency in 2018 (β = 0.130, p < 0.05). The possibility that DVS can predict sleep efficiency 2 years later was demonstrated.

BACKGROUND & AIMS
Improving sleep quality is important for an aging society. However, no study has been conducted on the association between dietary variety and sleep efficiency among older Japanese adults using longitudinal data. The current study is a longitudinal study that aimed to elucidate the association between dietary variety and sleep efficiency in older Japanese adults.
METHODS
This study was conducted among older adults (≥70 years old in 2016) in the metropolitan area of Tokyo, Japan, between 2016 and 2018. Dietary variety score (DVS) and sleep efficiency were determined for all participants and were used to assess dietary habits and sleep quality, respectively. A cross-lagged panel analysis was used to consider the prospective associations between DVS and sleep efficiency, and this analysis was performed before and after adjusting for possible covariates in the 2016 data.
RESULTS
After adjusting for age, sex, body mass index, current drinking status, current smoking status, exercise habits, living (alone or with others) style, the Japanese version of the Geriatric Depression Scale (Short Form), sleep duration and retiring time the DVS in 2016 predicted the sleep efficiency in 2018 (β = 0.130, p < 0.05).
CONCLUSION
The possibility that DVS can predict sleep efficiency 2 years later was demonstrated.
