- Although some neighborhood environmental factors have been found to affect depressive symptoms, few studies have focused on the impact of living in a hilly environment, i.e., land slope, on depressive symptoms among rural older adults. This cross-sectional study aimed to investigate whether a land slope is associated with depressive symptoms among older adults living in rural areas. Data were collected from 935 participants, aged 65 years and older, who lived in Shimane prefecture, Japan. Depressive symptoms were assessed using the Zung Self-Rating Depression Scale (SDS) and defined on the basis of an SDS score ≥ 40. Land slopes within a 400 m network buffer were assessed using geographic information systems. Odds ratios (ORs) with 95% confidence intervals (CIs) of depressive symptoms were estimated using logistic regression. A total of 215 (23.0%) participants reported depressive symptoms. The land slope was positively associated with depressive symptoms (OR = 1.04; 95% CI = 1.01–1.08) after adjusting for all confounders. In a rural setting, living in a hillier environment was associated with depressive symptoms among community-dwelling older adults in Japan.

- This longitudinal study examined the relationship between flexibility-activity and blood-pressure (BP) change among older adults in Japan. Our study included 452 older adults who took part in our survey in both 2012/2013 and 2017/2018. The seated systolic blood pressure (SBP) and diastolic BP (DBP) were measured both at baseline and at the 5 years follow-up. The frequencies of the different physical activities at baseline were assessed using a questionnaire. A generalized linear mixed model was used to estimate the non-standardized coefficient (B) of BP change associated with flexibility activity, after adjustments for sex, age, body mass index, smoking status, alcohol consumption, antihypertensive medication use, history of heart disease, walking time, and muscle-strengthening activity as a fixed-effect, and area of residence as a random-effect. Higher flexibility-activity frequency was significantly associated with reduced SBP (B = -0.77 [95% confidence intervals = −1.36, −0.18], p for linear trend = 0.01, p for quadratic trend = 0.85) and DBP (−0.33 [−0.71, 0.05], p for linear trend = 0.09, p for quadratic trend = 0.04). Engaging in flexibility activity for 3 days per week was significantly associated with a reduction in DBP (B = −4.16, 95% CI [−7.53, −0.79], p = 0.02) compared with that in the reference group (0 days per week). Interaction tests were not significant between basic variables (sex, age, BMI, and antihypertensive medication) and flexibility. In conclusion, higher flexibility activity frequency was associated with a reduction in BP in older adults. Future longitudinal and interventional studies should examine the effects of flexibility activity on cardiovascular disease prevention.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This cross-sectional study investigated the association between hilliness and walking speed in community-dwelling older adults, and whether it varied according to their car-driving status. Methods: Data were collected from 590 participants aged 65 and older living in Okinoshima Town, Shimane prefecture, Japan, in 2018. Comfortable walking speed (m/s) was objectively assessed. Hilliness was measured by the mean land slope (degree) within a 500-m or 1000-m network buffer around each participant's home using a geographic information system. A multiple linear regression examined whether the land slope was associated with walking speed, adjusted for sex, age, body mass index, smoking habits, alcohol consumption habits, exercise habits, chronic disease, and living arrangements. A stratified analysis by car-driving status was also conducted. Results: After adjusting for all confounders, the land slope within the 500-m or 1000-m network buffer was negatively associated with walking speed (B = -0.007, 95% CI [-0.011, -0.002]; B = -0.007, 95% CI [-0.011, -0.003], respectively). The stratified analysis by car-driving status showed that living in a hilly area was negatively associated with walking speed among non-drivers in the 500-m or 1000-m network buffer (B = -0.011, 95% CI [-0.017, -0.004]; B = -0.012, 95% CI [-0.019, -0.006]), though there were no associations among drivers. Conclusions: A hilly environment is positively associated with slow walking speed in community-dwelling older adults in Japan. Moreover, car-driving status potentially modifies the relationship between living in a hilly environment and slow walking speed.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The association between work-related moderate-to-vigorous physical activity (MVPA) and higher levels of stress response is recognized, but whether this association is moderated by regular exercise remains unclear. This cross-sectional study investigated whether exercise-based physical activity (PA) associates with lower levels of stress responses moderated by work-related MVPA. Methods: The study participants comprised 863 workers from 35 small and medium-sized enterprises in Shimane prefecture, Japan, collected through convenient sampling from April 2021 to August 2022. The Brief Job Stress Questionnaire was used to assess stress responses. Work-related MVPA and exercise-based PA were measured using questionnaires. Multiple linear regression was used to analyze the combined variables of work-related MVPA and exercise-based PA. The reference group had no weekly exercise-based PA and >60 min of work-related MVPA. Results: When work-related MVPA exceeded 60 min/day, flexibility activity or walking for ≥5 days/week (B = −3.53, 95% CI = −5.96, −1.11; B = −2.53, 95% CI = −4.90, −0.16) and muscle-strengthening activity 1–3 times/week (B = −3.52, 95% CI = −6.91, −0.12) were significantly associated with lower psychological stress response. Flexibility activity (B = −1.74, 95% CI = −3.01, −0.46) showed a similar link with physical stress response. When work-related MVPA was below 60 min/day, flexibility activity (B = −3.23, 95% CI = −6.01, −0.44; B = −3.29, 95% CI = −5.94, −0.63) or walking (B = −4.03, 95% CI = −6.62, −1.45; B = −3.10, 95% CI = −5.76, −0.44) practice 1–4 times/week and ≥5 times/week was significantly associated with lower psychological stress response. Conclusion: Exercise-based PA greatly and consistently associates with a lower level of stress responses moderated by work-related MVPA.

- OBJECTIVES: We investigated whether a moderate-to-vigorous physical activity (MVPA) level and walking time were associated with a hilly environment in rural Japanese older adults. DESIGN: Cross-sectional study. SETTING: Unnan city, Ohnan and Okinoshima towns in Shimane, Japan. PARTICIPANTS: Data were collected from 1115 adults from the Shimane CoHRE study, who were aged 60 years and older and living in rural Japan in 2012. MEASURES: We measured the total time spent on MVPA and walking using a Japanese short version of the International Physical Activity Questionnaire. The land slope in 400 or 800 m network buffers was assessed using the geographic information system. A multivariable Poisson regression model examined the prevalence ratios (PR) and 95% CIs of walking time or MVPA levels meeting the WHO guideline (>150 min/week) in the land slope categories (low, middle and high), adjusted for confounders. RESULTS: Engaging in the recommended level of MVPA was significantly associated with middle land slope (PR=1.07; p=0.03) and high land slope (PR=1.06; p=0.07) compared with low land slope in the 400 m network buffer, as well as with middle land slope (PR=1.02; p=0.48) and high land slope (PR=1.04; p=0.25) compared with the low land slope in the 800 m network buffer. Walking time was significantly associated with middle land slope (PR=1.13; p=0.04) and high land slope (PR=1.17; p=0.01) compared with low land slope in the 400 m network buffer, and with middle land slope (PR=1.09; p=0.16) and high land slope (PR=1.17; p<0.01) compared with low land slope in the 800 m network buffer. The sensitivity analysis found only a positive association between walking time and land slope in the 400 and 800 m network buffers. CONCLUSIONS: This study showed that a hilly environment was positively associated with walking time among older adults living in rural Japan.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: We aimed to examine the number of teeth and masticatory function as oral health indices and clarify their roles in the pathogenesis of sarcopenia and diabetes mellitus in communitydwelling older adults. Subjects and methods: This cross-sectional study was conducted with 635 older adults in Ohnan, Shimane Prefecture, in rural Japan. The number of teeth and masticatory function (measured by the number of gummy jelly pieces collected after chewing) were evaluated by dental hygienists. Sarcopenia status was assessed using handgrip strength, skeletal muscle index, calf circumference, and a possible sarcopenia diagnosis based on the Asian Working Group for Sarcopenia 2019. Diabetes mellitus status was defined as a hemoglobin A1c level ≥6.5% or self-reported diabetes. A multivariable logistic regression model was used to analyze the association between oral health, sarcopenia, and diabetes mellitus after adjusting for confounders. Results: After adjusting for all confounders, logistic regression analysis showed that the number of remaining teeth was negatively associated with a low level of handgrip strength (odds ratio [OR], 0.961; 95% confidence interval [CI], 0.932-0.992) and possible sarcopenia (OR, 0.949; 95% CI, 0.907-0.992). Higher levels of masticatory function were also negatively associated with a low level of handgrip strength (OR, 0.965; 95% CI, 0.941-0.990) and possible sarcopenia (OR, 0.941; 95% CI, 0.904-0.979). Logistic regression analysis showed that the number of remaining teeth and a higher level of masticatory function were negatively associated with diabetes mellitus (OR, 0.978; 95% CI, 0.957-0.999; OR, 0.976; 95% CI, 0.960-0.992, respectively). Conclusion: Our findings suggest that improvement in oral health, including the maintenance of masticatory function and remaining teeth, may contribute to the prevention of sarcopenia and diabetes mellitus in older adults.

Social participation and physical prefrailty in older Japanese adults : The Shimane CoHRE study
- 2020
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 15:12 December

Tidskriftsartikel (refereegranskat)abstract
- As older adults in an early stage (prefrailty) of frailty may return to a healthy state, it is necessary to examine the prevention of prefrailty. In this context, the number and types of social participation activities associated with physical prefrailty in community-dwelling older adults have remained relatively unexplored. This cross-sectional study investigates this issue by analyzing 616 participants living in Okinoshima, Shimane, a rural area of Japan, in 2019. Frailty was assessed using the 5-item frailty phenotype (unintentional weight loss, selfreported exhaustion, weakness, slow walking speed, and low physical activity). Data on social participation were obtained using a questionnaire based on participants' level of involvement with volunteer groups, sports clubs/groups, neighborhood associations, religious organizations/groups, and community elderly salons; their answers were categorized as "yes"if they answered "several times per year or more"and "no"if they answered "never."Binominal logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) of prefrailty by the number or types of social participation activities, adjusted for gender, age, body mass index, smoking, medication-taking, educational attainment, working status, and living arrangement. Of the 616 participants, 273 (44.3%) and 28 (4.5%) had prefrailty and frailty, respectively. The analysis showed that the number of social participation activities was significantly associated with lower odds of prefrailty (OR = 0.83; 95% CI, 0.74-0.94). Regarding the types of social participation, sports clubs/groups were associated with lower odds of prefrailty (OR = 0.47; 95% CI, 0.31-0.73). Participation in neighborhood associations was associated with prefrailty/frailty (OR = 0.57; 95% CI, 0.37-0.86). These results suggest that increasing the number of social participation activities or involvement in sports clubs/groups and neighborhood associations may be important to prevent physical prefrailty in the older population.

- Background: It has been shown that the socio-geographical environment of residential areas, such as altitude, affects the health status and health-maintenance behavior of residents. Here, we examined a hypothesis that altitude of residence would influence glycemic control in a general elderly population living in a rural area. Methods: A thousand and sixteen participants living in a mountainous region in Japan were recruited at health examinations. Hemoglobin A1c (HbA1c) was measured in serum as a parameter of glycemic control. The altitude of residence, distance to grocery stores and to medical facilities were estimated using a geographic information system. Results: Linear regression analysis confirmed a significant effect of the altitude on log HbA1c even after adjustment of other demographic and biochemical factors. When the distance to grocery stores or medical facilities were used instead of the altitude in a linear regression analysis, distance to secondary medical facilities alone showed a significant effect on HbA1c. Conclusions: We found a positive correlation between HbA1c level and residential altitude in a rural area of Japan. The altitude seemed to be a parameter substituting in the convenience of residential areas. Socio-geographical factors of living place, such as inconvenience, may influence glycemic control of the residents.

Tidskriftsartikel (refereegranskat)abstract
- Background: Varicose veins (VVs) cluster in families, but the familial risk of VVs has not been determined among adoptees. The aim was to estimate whether the familial transmission of VVs is related to disease in biological and/or adoptive parents. Study Design: The Swedish Multi-Generation Register and the Swedish Patient Register were used to follow all Swedish-born adoptees (born 1932 through 2004) that could be linked to both their biological and their adoptive parents (n = 80,214; 50% females). The risk of VVs was estimated in adoptees with at least 1 biological parent with VVs, but no adoptive parent with VVs (n = 187) compared with adoptees without a biological or adoptive parent with VVs (n = 1,758). The risk of VVs was also determined in adoptees with at least 1 adoptive parent, but no biological parent with VVs (n = 87), and in adoptees with both biological and adoptive parents affected (n = 21). Results: Adoptees from an affected biological parent, but no adoptive parent, were more likely to have VVs than adoptees from an unaffected biological or adoptive parent (standard incidence ratio [SIR] = 2.21; 95% CI, 1.91-2.55). The familial SIR for adoptees with both an affected biological parent and an adoptive parent was 4.58 (95% CI, 2.83-7.01). Adoptees with an affected adoptive parent but no biological parent were not at increased risk of VVs (SIR = 1.15; 95% CI, 0.92-1.42). Conclusions: These novel findings suggest that genetic factors make a strong contribution to the familial transmission of VVs from parents to offspring, although familial environmental factors might contribute.

Associations between dairy consumption and the physical function in Japanese community-dwelling older adults : The Shimane CoHRE study
- 2023
-
Ingår i: Geriatric Nursing. - 0197-4572. ; 53, s. 19-24
-
Tidskriftsartikel (refereegranskat)abstract
- Objectives: We investigated sex differences in the associations between dairy consumption and the physical function among community-dwelling older adults. Methods: Six hundred and fifty-six older adults (75.6 ± 6.4 years old) participated in this study. Dairy consumption (5-item Likert score) and the physical function (gait speed, handgrip strength, and skeletal muscle mass) were measured. The linear and quadratic associations between dairy consumption and the physical function measures were examined by a multiple linear regression analysis adjusted for covariates. Results: Among women, an increased dairy consumption was significantly linearly associated with greater hand-grip strength and faster gait speed (both p<0.05) after adjusting for covariates. Among men, dairy consumption was not associated with the physical function measures. Dairy consumption was not associated with the muscle mass in either sex. Conclusions: Increased dairy consumption was associated with a superior physical function in older women.
