“…Our empirical findings showed that maintaining good eating habits and food preferences are significantly associated with decreased dementia risk, which is consistent with some previous results 18 . Walking (more than three times per week) and watching TV (almost every day) are also practical activities that aid dementia prevention 19,20 …”

Aim In this study, we seek to empirically understand the relationship between lifestyle habits and dementia risk. Methods Through an original online survey, we first confirm the significant difference in the dementia risk indicators between good and bad lifestyle habits. Then, using regression analysis to hold other factors equal, we examine the relationships between lifestyle habits and an aggregate dementia risk indicator. Results Through the t‐test results, we find that the average scores of dementia risk for respondents avoiding good habits and preferring bad habits are significantly higher than those of the respondents favoring good habits and avoiding bad habits. Our empirical findings showed that Japanese‐style dietary habits significantly correlate with a decreased dementia risk. An additional 1‐point increase in eating habits will reduce dementia risk scores by 0.148 points, on average. Furthermore, we also confirm that walking (more than three times per week) and watching TV (almost every day) help prevent dementia. Conclusions We conclude that maintaining a good lifestyle helps prevent dementia. In particular, good eating habits, both in terms of types of food and eating routines, are essential to avoid the development of dementia. Most of these lifestyle habits belong to the targets of the “Health Japan 21” project. Therefore, our findings might provide some convincing evidence for promoting the project, which will not only extend healthy life expectancy, but also reduce the increasing number of older adults with dementia.

“…Our primary analyses were robust to adjustment for multiple comparisons. Results demonstrating the importance of addressing modifiable risk factors are being reported in many countries (Perales et al, 2018;Yuan et al, 2018), and thus our findings likely have implications in other countries and populations. Nevertheless, our study cohort reflects the racial/ethnic proportions of the underlying older adult population and is largely white; replication is needed in other types of populations.…”

Objectives:To assess independent and joint effects of pairs of vascular and cardiometabolic risk factors (VCMRFs) in relation to risk of all-cause dementia.Design:Population-based longitudinal cohort study of cognitive impairment. We used an algorithm to select pairs of VCMRFs and tested their joint effects in time-dependent Cox models. We used attributable proportions (AP) to measure the proportion of risk from interactions beyond any additive effect.Setting:Economically depressed small-town population.Participants:Adults age 65+ years with up to 10 yearly study visits (N=1701, median (Q1, Q3) age, 78 (71.0, 83.0), 62.3% female, 94.9% white).Results:Among 1701 participants free from prevalent dementia with at least one follow-up visit, 109 developed incident all-cause dementia. In pairings of APOE*4 with hypertension (HTN) and congestive heart failure (CHF), the variables contributed independently and additively to all-cause dementia risk. In pairings of APOE*4 with stroke and stroke with CHF, the variables demonstrated independent contributions to all-cause dementia risk; their joint effects showed excess detriment demonstrating synergistic interactions (joint HR [95% CI]: 28.33 [6.74, 119.01] and 50.30 [14.57, 173.57] respectively, fully adjusted models). Physical activity (PA) was independently associated with lower all-cause dementia risk when paired with APOE*4, stroke, and CHF in unadjusted models; these associations did not survive covariate adjustment. The joint effect of low PA and APOE*4 was associated with additively increased all-cause dementia risk (joint HR [95% CI]: 4.61 [2.07, 10.23], fully adjusted model).Conclusions:Reduction of VCMRFs, including low PA, could be valuable for dementia prevention, especially among APOE*4 carriers.

“…The RBL questionnaire was composed through existing study analysis [ 10 , 12 , 13 , 31 , 32 , 33 , 34 , 35 , 36 ]. It was designed to check the lifestyle patterns in residential life in three aspects: (1) quality of home life indicators (general frequency 1: rarely—5: always), (2) daily home activities (daily frequency 1: never—5: more than 3 h), and (3) social events at home (monthly frequency 1: less than 1–5: more than 4 times).…”

“…In this study, it was very important to develop an RBL measurement tool that could be the basis for clustering. To this end, measurement items were constructed by analyzing studies related to the lifestyles of older people [ 10 , 12 , 13 , 31 , 32 , 33 , 34 , 35 , 36 ] ( Appendix A ). To further define the concept of residential life, existing studies on housing and residential lifestyle were also analyzed [ 39 , 40 ].…”

Globally, the percentage of older people in the general population is growing. Smart homes have the potential to help older adults to live independently and healthy, improving their quality of life, and relieving the pressure on the healthcare and social care systems. For that, we need to understand how older adults live and their needs. Thus, this study aims to analyze the residentially-based lifestyles (RBL) of older adults and segment them to compare and analyze the real needs of smart home functions for each group. To identify a person’s RBL, a questionnaire was designed to include questions about activities at home, social events, quality of life, etc. This study surveyed 271 older Koreans. As a result of the survey on RBL, five groups with different characteristics were clustered. Finally, each groups’ features and the differences in their needs for smart home functions were compared and analyzed. The priority of needed functions for each group was found to be significantly different. In a total of 26 smart home functions, there were meaningful differences in the needs for 16 functions among the groups. This study presents the results in South Korea, according to older adults’ RBL and their smart home needs.

Associations between modifiable lifestyle factors and multidimensional cognitive health among community-dwelling old adults: stratified by educational level

Abstract: Background: Cognition is multidimensional, and each domain plays a unique and crucial part in successful daily life engagement. However, less attention has been paid to multi-domain cognitive health for the elderly, and the role of lifestyle factors in each domain remains unclear.
