Relationship Between Oral Health, Quality of Life, and Comprehensive Health Literacy in Community-Dwelling Older Adults.

Background and purpose: Oral health affects systemic health and the importance of maintaining good oral health is acknowledged. The high prevalence of oral diseases is associated with low health literacy (HL). Therefore, the purpose of this study was to investigate whether comprehensive HL in community-dwelling older adults is associated with objective oral hygiene and oral health-related quality of life (OHRQoL). Methods: Participants aged ≥65 years completed a self-administered questionnaire. On the same day, data collected with the oral health assessment tool were used to assess participants' objective oral status. The questionnaire included the general oral health assessment index to measure OHRQoL and the short version of the European Health Literacy Survey Questionnaire to assess comprehensive HL. Data were analyzed by univariate and multiple logistic regression. Results: In total, 145 people consented to participate in this study, of whom 118 (81.4%) responded effectively. Of the 118 participants, 18% recorded a rating of "unhealthy" for oral cleanliness in objective oral hygiene. Multiple logistic regression analysis identified comprehensive HL as a related factor for both oral cleanliness and OHRQoL (odds ratio = 5.00 and 3.33, p < 0.01 and p < 0.05, respectively). Implications for Practice: These findings indicate that comprehensive HL changes clinical outcomes. Because older adults often have comorbidities as well as oral health problems, it is important for nurses to assess HL during follow-up for comorbidities and take the opportunity to provide personalized oral health guidance and improve OHRQoL.

Long-term health-related quality of life of total hip arthroplasty patients and cost-effectiveness analysis in the Japanese universal health insurance system.

AIM: Total hip arthroplasty can effectively improve patients' motility with end-stage osteoarthritis. This study aimed to: (1) compare gradual changes in utility values with total hip arthroplasty and estimated values without; (2) evaluate total hip arthroplasty cost-effectiveness; and (3) evaluate cost-effectiveness by age, diagnosis, and comorbidity. METHODS: Patients who underwent total hip arthroplasty between January 2008 and December 2009 were included. Patients completed the EuroQol preoperatively and at 1, 3, 5 and 7 years postoperatively. To derive the quality-adjusted life years gained, a utility score was obtained from the EuroQol item scores and combined with 7 years, and estimates were obtained by discounting the postoperative 1-year utility value at an annual rate of 2%-4%. Mixed-effects regression models were used to compare the estimated and the measured utility values. RESULTS: Mean total cost was 1,921,849 yen, and quality-adjusted life years gain score was 1.746 with per cost as 1,100,715 yen. Compared with actual measurements, the estimated values from 1 to 7 years post-surgery differed significantly, and interaction was observed. Regarding age, the older the patient, the higher the cost per quality-adjusted life years. Patients with lower preoperative physical function had higher quality-adjusted life years gains, while the cost per quality-adjusted life years was lower. CONCLUSIONS: Total hip arthroplasty was cost-effective. Compared with actual measurements, the estimated utility values from 1 to 7 years post-surgery significantly differed. Even among older patients and those with impaired preoperative physical functions, its cost was lower than patients' willingness to pay in Japan.

Changes in Physical Activity Due to Fear of COVID-19 and Its Impact on Depression Among Post-Liver Transplant Patients in Japan: A Longitudinal Survey Study.

BACKGROUND Regular physical activity (PA) is important for maintaining mental and physical health after liver transplantation (LT); however, the fluctuations in routine PA during COVID-19 and its putative impacts are currently unknown. This study examined the changes in PA during the COVID-19 pandemic and explored its association with fear and depression during the pandemic. MATERIAL AND METHODS This longitudinal study included 83 LT patients whose PA was measured using the short form of the International Physical Activity Questionnaire before and during COVID-19. Fear of COVID-19 was estimated based on previous studies, and depression was assessed using the Patient Health Questionnaire-9. Participants were also asked about important sources of information on COVID-19. PA was classified as inactive or active depending on the changes in PA, and logistic regression analyses with PA as a dependent variable were conducted to explore the associations among PA, depression, and fear of COVID-19. RESULTS Moderate and high PA exhibited decreasing trends before and during the COVID-19 pandemic, especially in males. Fear of being infected with SARS-CoV-2, the virus that causes COVID-19, while shopping was significantly higher in females and was significantly independent of inactivity during the COVID-19 pandemic. Only 1 patient reported that their transplant center was their main source of information about COVID-19. Only 4.9% of the LT participants were depressed. CONCLUSIONS Our study results indicate the need to support the provision of accurate information about COVID-19 by health care professionals in transplant centers, especially for patients with low PA, to prevent PA decline in LT patients.

The effect of real-time monitoring of physical activity intensity in diabetic patients.

AIM: To evaluate the effects of an intensity display type accelerometer on diabetic patients' physical activity. METHODS: This was a two-arm, non-randomized controlled study. Both groups received information about the recommendation of 150 min/week moderate-to-vigorous physical activity (MVPA). The intervention group used an intensity display type accelerometer to monitor their physical activity intensity for 10 days at baseline and 3 months later. We compared intervention and control groups after 3 and 6 months. Primary outcomes were MVPA and number of steps over 7 days. Secondary outcomes were glycosylated hemoglobin (HbA1c), body mass index, and self-management. RESULTS: Of 62 participants, 30 and 32 were included in the intervention and control groups, respectively. Mean age in each group was 59.7 ± 10.8 and 58.8 ± 10.2 years, and mean HbA1c was 6.9 ± 0.9% and 6.9 ± 0.8%, respectively. There were no significant differences between the intervention and control groups at either time point, and no outcomes showed significant changes. In a subgroup analysis by physical activity intensity, MVPA of active individuals in the control group significantly decreased at 6 months from baseline. MVPA and number of steps among inactive individuals in the intervention group significantly increased at 6 months from baseline. Self-management of the intervention group showed a trend toward improvement, but HbA1c and body mass index showed no significant change. CONCLUSIONS: Monitoring physical activity intensity led to increased MVPA of inactive patients and maintained MVPA of active patients with diabetes mellitus. This straightforward intervention could be applied in clinical practice.

Development and evaluation of the sedentary behavior and light-intensity physical activity questionnaire.

[Purpose] To describe our newly developed Sedentary Behavior and Light-Intensity Physical Activity Questionnaire and examine its reliability and validity. [Participants and Methods] We identified and selected self-reported items through a literature review and interviews with 11 inactive individuals. Thirty-one individuals with lower limb prostheses and an expert panel assessed the content validity of the integrated items and identified 17 items. Patients who had undergone lower limb surgeries were regarded as inactive individuals, and 112 patients completed the questionnaire twice for test-retest reliability and wore an accelerometer for criterion validity. The ethics committee of Kyushu University approved this study (2019-126 and 2019-273). [Results] Item analysis was revised to the Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 (six light-intensity physical activity and four sedentary behavior items) because of the floor effect. The test-retest correlation coefficient showed high reliability. Moderate to weak correlation coefficient was observed between the questionnaire and accelerometer (light-intensity physical activity: 0.43 and sedentary behavior: 0.20), and the Bland-Altman plots indicated no bias. [Conclusion] The Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 had acceptable validity and reliability among inactive individuals and it could be used for studying light-intensity physical activity.

Relationships of accelerometer-determined physical activity with obesity, hypertension, diabetes, dyslipidemia, and health-related quality of life in patients after liver transplantation.

The contribution of physical activity (PA) to the prevention of metabolic abnormalities following liver transplantation (LT) has not been well documented. We aimed to assess PA in post-LT patients and to quantify its relationships with the development of postoperative metabolic abnormalities and health-related quality of life (HRQOL). We recruited 111 patients who had undergone LT ≥ 6 months previously. PA was measured by accelerometry, and HRQOL was evaluated using SF-8. PA was quantified as the number of steps per day, and the time spent performing moderate-to-vigorous PA and light PA per week. The prevalence of hypertension, diabetes, and dyslipidemia increased more than twofold following LT. The proportion of the participants with a sedentary lifestyle (<5000 steps/day) was 36%. Logistic regression analysis showed that postoperative hypertension and obesity were associated with preoperative body mass index and the number of steps taken (in 2000 steps/day increments). Preoperative diabetes was associated with obesity, and PA was associated with physical function-related HRQOL scores. Thus, increasing the number of steps taken per day has the potential to reduce hypertension and obesity, and PA could improve physical function-related HRQOL in patients following LT.

Prospective study of objective physical activity and quality of life in living donor liver transplant recipients.

AIM: The aims of this study were to: (a) describe the physical activity (PA) and quality of life (QOL) in living donor liver transplant (LDLT) recipients pre-operatively and at 3 months and 6 months post-operatively; (b) compare PA and QOL at 6 months post-operatively with a healthy control group; and (c) explore pre-operative factors that predict PA changes. METHODS: Patients over 20 years of age who were undergoing LDLT were recruited. PA was measured based on the number of steps/day and time spent performing moderate-to-vigorous PA (MVPA) during 1 week using an accelerometer. QOL was assessed based on a physical (PCS) and mental (MCS) component summary of the eight-item Short-Form Health Survey. The LDLT and healthy control groups were matched for age (±3 years) and gender. Pre-operative factors predicting a change in PA were calculated using a generalized linear mixed model. RESULTS: Twenty-four patients completed the study. By 6 months post-LDLT, the MCS and PCS were comparable to those in the control group. The number of steps (3,887 steps/day) and MVPA (29.3 min/week) showed significant improvement by 6 months post-operatively, but remained much lower compared with those in the control group. The multivariate analysis showed that younger age (p < .01, p = .04) and higher skeletal muscle mass (SMM; p < .01, p = .03) were predictors of improvement in number of steps and MVPA. CONCLUSION: This study suggests the need for pre-operative interventions by healthcare professionals that focus on outcomes such as improving low SMM to facilitate post-operative PA recovery.

Cross-cultural adaptation, reliability and validity of the Japanese version of the Hospital for Special Surgery Hip Replacement Expectations Survey.

BACKGROUND: The Hospital for Special Surgery Hip Replacement Expectations Survey (HSS-THRES) is used in many countries to determine patient expectations before surgery. This study aimed to assess the reliability and validity of the Japanese version of HSS-THRES. METHODS: A total of 134 patients scheduled for total hip arthroplasty (THA) underwent a self-administered preoperative survey questionnaire. Patient's expectation and quality of life (QOL) were measured using the Japanese version of HSS-THRES, overall expectations for THA, Oxford hip score (OHS), and EuroQol-5D (EQ-5D). Some patients completed the Japanese version of HSS-THRES and the overall expectations for THA after a ten-day interval. Cross-cultural adaptation was validated by an expert committee comprising health professionals, a methodologist, language experts, and orthopedic specialists. The internal consistency was evaluated by the Cronbach α coefficient. The test-retest reliability was examined using the intraclass coefficient correlation (ICC) and the Bland and Altman analysis. To test the construct validity, nine priori hypotheses were tested by correlation analysis between the Japanese version of HSS-THRES and two QOL scales, and by examining the association with demographic variables. RESULTS: A total of 116 patients completed four scales. Patients were predominantly female (75.9%), with an average age of 62.2 ± 11.7. In the cross-cultural adaptation, all patients responded to the questionnaire without problems. The Japanese version of HSS-THRES showed good internal consistency (Cronbach α: 0.9). ICC was 0.94 and Bland-Altman analysis indicated no bias. The correlation between Japanese HSS-THRES and overall expectations for THA was high (r = 0.67). Similarly, the correlation with the OHS was higher than that with EQ-5D. A total of 77.8% of the hypotheses were confirmed. CONCLUSIONS: The Japanese version of HSS-THRES showed good cultural acceptability, high reliability, and validity to evaluate preoperative expectations for THA patients.

Expectations and depression in patients who have undergone total hip arthroplasty in Japan: A prospective cohort study.

BACKGROUND: Patients with hip osteoarthritis may be severely depressed preoperatively due to pain and limited daily-living activities. Hence, evaluating their expectations preoperatively might underestimate their true hopes regarding the upcoming total hip arthroplasty (THA). AIM: We aimed to assess changes in patients' level of depression, understand their expectations and fulfillment, and identify factors affecting fulfillment. METHOD: We performed a longitudinal study of 366 Japanese patients who had undergone THA during 2005-2006. Those with THA of the contralateral hip were excluded. Patients' expectations, fulfillment, depression, and physical function were assessed perperative and at 6 weeks and one year postoperatively using our own questionnaire, the Arthritis Impact Measurement Scale 2, and by the Oxford Hip Score . Logistic regression analysis was applied to identify independent predictors of expectation fulfillment. RESULTS: At 6 weeks, 78.1% expressed expectation fulfillment and drastic alleviation of depression. Preoperative depression and fulfillment of patient expectations at 6 weeks were significant predictors of expectation fulfillment at 1 year (95% confidence intervals: 1.01-2.48 and 2.30-9.92, respectively. CONCLUSIONS: It is worthwhile for health providers to investigate patients' expectations early in the postoperative period by considering their preoperative depression to confirm fulfillment of expectations.
