Relationship between Dietary Patterns and Subjectively Measured Physical Activity in Japanese Individuals 85 Years and Older: A Cross-Sectional Study

Abstract

High-quality diets and regular physical activity (PA) are considered healthy behaviors (HBs). HBs are associated with many health outcomes and are expected to improve quality of life. Although implementing HBs is important, the relationship between dietary patterns (DPs) and PA has not been well investigated, especially among those aged ≥ 85. This study used data from the Tokyo Oldest Old survey on Total Health study to examine the relationship between DPs and PA in a cross-sectional study. The dietary survey used the brief self-administered diet history questionnaire to estimate the intake of 58 foods. After energy adjustment, principal component analysis was performed to identify major DPs. A validated questionnaire was used to evaluate PA, and linear regression analysis was used to investigate the association between DPs and PA, considering confounders. A total of 519 participants were included. Three major DPs (‘Various plant foods’, ‘Fish and mushrooms’, ‘Cooked rice and miso soup’) were identified. ‘Various plant foods’ was similar to DPs previously named ‘Healthy’ or ‘Prudent’, and its trend was positively associated with higher PA. This study observed the implementation of HBs even among those aged ≥ 85, suggesting that a trend toward a healthier diet is associated with higher PA.

Mediterranean Diet Adherence Is Associated with Favorable Health-Related Quality of Life, Physical Activity, and Sleep Quality in a Community-Dwelling Greek Older Population

“…In contrast, Foscolou et al found similar physical activity levels in people with varying levels of MD adherence; however, this study included both the middle-aged and older-aged Greek population, which may influence the final findings concerning the individual life stage of older adults [8]. Regarding diet quality and physical activity levels, Japanese people over 85 years old that had a higher diet quality showed better physical activity levels [87]. Similarly, in Polish adults, sedentary behaviors correlated with lower diet quality [88].…”

Association between dietary patterns and subjective and objective measures of physical activity among Japanese adults aged 85 years and older: a cross-sectional study

“…DP2 ‘red meats and coffee’ is identical to that in the same age group in the UK, characterised by red meat intake, and DP3 ‘bread and processed meats’ is similar to the Western pattern. In a study on adults aged ≥ 85 in central Japan, a DP characterised by a high intake of plant-based foods and a high food diversity was positively associated with subjectively measured PAI ( 33 ) . In Croatia (Zagreb City), using the Elderly Dietary Index Score, ten foods (meat, fish, fruits, vegetables, grains, legumes, olive oil, alcohol, bread and dairy products) were assessed, and their association with PA was examined.…”

Exploring the potential relationship between short sleep risks and cognitive function from the perspective of inflammatory biomarkers and cellular pathways: Insights from population‐based and mice studies

“…The computation of the SII level hinges upon the following formula: (platelet count × neutrophils count)/lymphocytes count. [32][33][34][35] Referring to previous literature, 36 SII was set as a categorical variable according to the mean value.…”
