RESUMEN
Introduction: This case study aimed to demonstrate how cooking class activities held in collaboration with the Ajinomoto Foundation (TAF) and a consumer cooperative after the Great East Japan Earthquake contributed to the resilience of the affected community. Methods: With reference to the logic model, evaluation indicators for the case study were established. We focused on the Iwate Seikatsu Kyodo Kumiai (Iwate Co-op). We organized 120 continuation cases out of the eight-and-a-half-year activity records of the project owned by TAF (April 2012 to March 2020). The Iwate Co-op was one of the 120 continuing cases and had special features, including awareness that its members were responsible for the community. Results: The collaboration revealed three effects. First, owing to the encounter and collaboration with TAF, the cooking class was continuously conducted even after TAF withdrew from the disaster-affected areas. Second, the Iwate Co-op trained some of its members as food support staff to run the cooking class independently and was actively involved in obtaining the necessary budget for the operation, consequently leading to the independent activation of member activities. Third, they developed a cooking class project in inland areas other than disaster-stricken areas, assuming that they could incorporate the project into their existing activities, as food problems affected people beyond disaster victims. Conclusion: The collaborative food support project of the Iwate Co-op and TAF contributed to the resilience of the affected people and communities by strengthening bonds and solidarity among residents and organizations. The key to success was the fusion of a traditional sense of independence in the co-op with TAF's mission and technical know-how. The partnership between the Iwate Co-op and TAF allowed the former to aim toward developing food support activities in the affected areas, accelerating the resilience of the community in the Iwate Prefecture.

BACKGROUND: Both metabolic syndrome (MetS) and depression are high priority health problems, especially for working age. Numerous studies have explored the link between metabolic syndrome and depression; however, not all of them have consistently demonstrated an association. The objective of this study was to determine whether there is an association between MetS and depression by analyzing extensive real-world data (RWD). METHODS: Our data was drawn from insurance claims and health checkups of local government officials across all prefectures in Japan except for Tokyo in the 2019 fiscal year. According to the number of months with diagnosis of depression and prescription of antidepressants, the study participants were classified into the following categories: Certainly not Depression (CN), Possibly not Depression (PN), Possible Depression (PD), and Certain Depression (CD). Associations between MetS and its components-visceral obesity, hypertension, hyperlipidemia, and diabetes- and these categories of depression were analyzed by logistic regression. RESULTS: The depression categories of the 130,059 participants were as follows: CN 85.2%; PN 6.9%; PD 3.9%; and CD 4.1%. For men, the adjusted odds ratio (AOR) for MetS were PN 0.94 (95% CI: 0.86-1.02), PD 1.31 (1.19-1.43), and CD 1.63 (1.50-1.76), with reference to CN. For women, AOR of MetS were PN 1.10 (0.91-1.32), PD 1.54 (1.24-1.91), and CD 2.24 (1.81-2.78). Among the MetS components, visceral obesity, hyperlipidemia, and diabetes were significantly associated with depression categories. CONCLUSIONS: In this study, we found a significant association between MetS and depression, this association being similar to that previously reported. Our findings provide robust evidence for linkage between MetS and depression, suggesting that analysis of RWD is useful for providing concrete evidence.

ObjectiveãCoronavirus disease 2019 (COVID-19) became a global public health threat, and local public health centers in Japan implemented an infectious disease response to support patients. The response was subsequently modified to meet the needs for each of the five waves of infection. The study aim was to analyze the characteristics and courses of the disease in patients with COVID-19 at a single public health center. The study period included the first through fifth waves of the disease.MethodsãWe utilized a descriptive epidemiological design in this study and data of patients with COVID-19 from one administrative district in Tokyo, Japan. We analyzed age, gender, nationality, symptoms at diagnosis, the route of infection, the recovery environment, and associated morbidity intervals, including case fatality rate, days from symptom onset to diagnosis, days from diagnosis to hospitalization, and recovery time for each of the first through fifth waves.ResultsãFrom February 2020 to November 2021, 11,252 patients were diagnosed with COVID-19. Specifically, in the first wave, 151 patients were diagnosed, followed by 803 in the second wave, 2,406 in the third wave, 1,480 in the fourth wave, and 6,412 in the fifth wave. Hospitalization was the primary recovery environment during the first wave, while home recovery became the primary approach from the third wave onward. The case fatality rate was highest during the first wave, likely because of limited testing and treatment options for severe cases. The median time from onset to diagnosis was seven days in the first wave, significantly longer than for the other waves. The median time from diagnosis to hospitalization was one day in the first through fourth waves but three days in the fifth wave. The extension of this interval suggests that hospitalization was delayed in this wave as the number of severe patients increased rapidly, likely because of the novel COVID-19 variant.ConclusionãThis study of patients testing positive for COVID-19 provides valuable insights into the characteristics and courses of the pandemic within this district. These findings can inform regarding the development of effective strategies to manage the ongoing COVID-19 pandemic and other future emerging infectious diseases.

ObjectivesãJapan has a high prevalence of low back pain among older adults requiring long-term care, which results in increasing expenses; therefore, prevention measures are necessary. This study aimed to examine the relationship between low back pain and physical activity and sitting time according to sex and age (65-74 years [young-old adults]; ≥75 years [old-old adults]) who had not received long-term care certification.MethodsãA self-administered survey was mailed to 7,080 adults >65 years of age residing in Tsuru City (Yamanashi Prefecture, Japan) from January to February 2018, and had not received long-term care certification. Demographic information, health status (body mass index and medical history), lifestyle (dietary habits, alcohol consumption, and smoking), presence of low back pain, physical activity, sitting time, and social participation were measured. Low back pain was evaluated by asking, "Did you experience pain in parts of the body other than the knees for the past month?" Those who answered, "experienced low back pain" were categorized as "with low back pain". The short form of the International Physical Activity Questionnaire was used to assess physical activity, which was categorized into three groups: <150, 150-299, and ≥300 min/week. Sitting time was divided into two groups: <480 and ≥480 min/day. Multiple logistic regression analysis was used to determine the association between low back pain and physical activity and sitting time, according to sex and age.ResultsãOf the 7,080 individuals surveyed, 4,877 responded (2,217 male, 2,660 female), corresponding to a response rate of 68.9%. The number of older adults with low back pain was 1,542 (31.6%) including 673 (30.4%) males and 869 (32.7%) females. The rate of low back pain in young-old adults was 29.8% and 33.6% in old-old adults. There was no significant relationship between lower back pain and physical activity among the young-old adults. In the old-old adults, there was a significant relationship in the male ≥300 min group (odds ratio [OR] 0.66 [95%CI 0.48-0.89]), and in both female 150-299 (OR 0.69 [95%CI 0.48-0.99]) and ≥300 (OR 0.59 [95%CI 0.44-0.80]) min/week groups.ConclusionãThe complaint rate for low back pain was approximately 30%, regardless of sex or age. These results suggest that interventions to prevent low back pain are necessary. Moreover, physical activity, but not sitting time, was associated with low back pain in both males and females among the old-old adults.

ObjectivesãIn Japan, schools of public health (SPH) have engaged in professional education focusing on five core disciplines: epidemiology, biostatistics, social and behavioral science, health policy and management, and occupational and environmental health. However, empirical information is lacking regarding the current state of this education and its associated challenges in Japan. In this article, we showcase this issue, using the master of public health (MPH) course at Teikyo University Graduate School of Public Health (Teikyo SPH) as an example.MethodsãWe summarized the current objectives and classes required to complete the MPH course at Teikyo SPH, using the course guideline published in 2022. Current issues and possible future directions in the course were summarized based on the opinions of Teikyo SPH faculty members.ResultsãFor epidemiology, lectures and exercises were designed to focus on how to formulating public health issues, collecting and evaluating data, and causal inference. Issues related to the design included ensuring that students had the necessary skills to apply epidemiology to emerging issues, and catching the course up with evolving techniques. For biostatistics, lectures and exercise classes focused on understanding data and statistics, as well as performing analyses. Issues included the understanding of theories, setting the course level, and a lack of appropriate education materials for emerging analytical methods. For social and behavioral science, lectures and exercise classes focused on understanding human behaviors and actions for problem solving. Issues included learning various behavioral theories in a limited timeframe, the gap between the lectures and various needs, and nurturing professionals who had the skills to perform in practical settings. For health policy and management, lectures, exercise classes, and practical training classes focused on identifying and solving problems in the community and around the world, and on integrating the disparate viewpoints of health economics and policy. Issues included few alumni who actually found work globally, a lack of students working in local or central administrations, and insufficient perspectives on rational/economic thinking and macro-economic transitions. For occupational and environmental health, lectures, exercise classes, and practical training classes focused on learning the occupational and environmental impacts of public health issues, and their countermeasures. Challenges included enriching the topics with regard to advanced technologies, environmental health, and socially vulnerable populations.ConclusionãThrough these reflections on MPH education at Teikyo SPH, the following recommendations are considered essential in order to prepare improvements to the program: reorganizing the curriculum to meet the needs of the day, accepting students with various backgrounds, addressing the increasing knowledge and skills that need to be acquired by the students, and enhancing the powers of professors to implement changes.

BACKGROUND: Health literacy (HL) has gained increasing attention as a factor related to health behaviors and outcomes. This study aimed to investigate geographic differences in HL levels and effect modification by geographic area on their relationship with self-rated health in the Japanese population using a nationwide sample. METHODS: Data for this study were derived from a nationally representative cross-sectional survey on health information access for consumers in Japan using a mailed self-administered questionnaire in 2020 (INFORM Study 2020). Valid responses from 3,511 survey participants, selected using two-stage stratified random sampling, were analyzed in this study. HL was measured using the Communicative and Critical Health Literacy Scale (CCHL). Multiple regression and logistic regression analyses were conducted to examine the associations between geographic characteristics and HL and effect modification on the association between HL and self-rated health by geographic area, controlling for sociodemographic characteristics. RESULTS: The mean HL score was 3.45 (SD = 0.78), somewhat lower compared with previous studies on the Japanese general population. HL was higher in Kanto area than in Chubu area, after controlling for sociodemographic factors and municipality size. Furthermore, HL was positively associated with self-rated health after controlling for sociodemographic and geographic factors; however, this association was more evident in eastern areas than in western areas. CONCLUSION: The findings indicate geographic differences in HL levels and effect modification by geographic area on the relationship between HL and self-rated health in the general Japanese population. HL was more strongly associated with self-rated health in eastern areas than in western areas. Further investigation is needed to explore the moderating effects of areal features, including the distribution of primary care physicians and social capital, when formulating strategies to improve HL in different contexts.

BACKGROUND: Little is known about the vulnerable populations and problem drinking in terms of health inequality. This study aimed to investigate the relationship between health indifference estimated by Health Interest Scale (HIS) and problem drinking identified by the Alcohol Use Disorder Identification Test (AUDIT). METHODS: A cross-sectional study was conducted utilizing data from a nationwide internet survey in Japan in 2022. The number of total participants was 29,377, with 49% of them being male, and the mean age was 47.9 (±17.9) years. The participants were categorized into the following groups based on the quintiles of HIS score: health indifference (0-16), low health interest (17-20), middle health interest (21-22), middle-high interest (23-26) and high health interest (27-36) groups. Problem drinking was identified as AUDIT score of ≥8 points. RESULTS: The association between health indifference and problem drinking was explored through logistic regression with adjustment for various socioeconomic status, such as education, income level, and occupation; the adjusted odds ratio (aOR) was 1.72 [95% confidence interval (CI): 1.51-1.95]. CONCLUSION: Health indifferent or lower health interest groups were a vulnerable population for problem drinking, regardless of their socioeconomic status. It could be useful to identify the health indifferent group through HIS and to monitor the impact of health intervention for this group for the reduction of health inequality.

BACKGROUND: The relationship between obesity and nonalcoholic fatty liver disease and renal hyperfiltration is controversial. This study aimed to assess the correlations of body mass index and fatty liver index, respectively, with renal hyperfiltration in non-diabetic subjects, considering age, sex, and body surface area. METHODS: This cross-sectional study assessed the Japanese health check-up data (FY2018) of 62,379 non-diabetic individuals from a health insurance database. Renal hyperfiltration is the ≥ 95th percentile of estimated glomerular filtration rate (derived by Chronic Kidney Disease Epidemiology Collaboration formula) by gender and age in healthy subjects. After adjusting for potential confounders, multiple logistic regression models were applied to evaluate the correlation of renal hyperfiltration with body mass index categories and fatty liver index (10 equal parts). RESULTS: A negative and positive correlation, respectively, were noted when the body mass index was < 21 and ≥ 30 in women; however, a positive correlation was noted for BMI < 18.5 and ≥ 30 in men. Renal hyperfiltration prevalence increased when fatty liver index increased for both sexes; the cutoff value for fatty liver index was 14.7 for women and 30.4 for men. CONCLUSIONS: Body mass index and renal hyperfiltration correlated linearly in women; however, in men, the correlation was U-shaped; therefore, differing by sex. However, fatty liver index correlated linearly with renal hyperfiltration in both sexes. Non-alcoholic fatty liver disease might be associated with renal hyperfiltration; Fatty liver index is a simple marker that can be obtained from health check-ups. Since a high fatty liver index correlated with renal hyperfiltration, it may be beneficial to monitor the renal function in such a population.

AIM: This study examined the relationship between continuity of social participation and progression of frailty among community-dwelling older adults, by baseline frailty level. METHODS: This study was part of a 3-year community-based cohort study among adults aged ≥65 years, living independently in a rural municipality in Japan. Mail surveys were carried out in 2016, 2018 and 2019. This study involved 2799 participants who responded to the question about social participation in every survey. Frailty was evaluated by Kihon Checklist total scores. Social participation was categorized into consistent non-participation, interrupted recent non-participation, interrupted recent participation and consistent participation. We assessed the relationship between social participation and change in frailty scores using general linear regression analysis, stratifying the participants into groups by their frailty level at baseline. RESULTS: There was a smaller frailty score increase in the robust (ß -0.61, 95% CI -0.99 to -0.22) and prefrail groups (ß -0.73, 95% CI -1.18 to -0.27) for consistent participation than consistent non-participation. Interrupted recent participation showed significant suppression in the prefrail group (ß -0.96, 95% CI -1.60 to -0.32). Social participation had no clear effect on progression in the frail group. CONCLUSIONS: Consistent social participation might reduce the progression of frailty in robust and prefrail people. Inconsistent participation might also help to reduce progression in prefrail older adults. It is important for prefrail older adults to return to their social activities and continue to engage as long as possible, even if their participation was intermittent in the past.

Coronavirus disease 2019 (COVID-19) vaccination of adolescent and young adults is important for infection control. Factors influencing vaccination behavior in this age group include the source of information about the vaccine and social norms. However, there are few studies on factors influencing vaccination behavior among Japanese university students. This study aimed to assess beliefs, attitudes, and sources of information about the COVID-19 vaccine among university students in Japan. A cross-sectional online questionnaire survey was conducted among students in Teikyo University, Japan in September, 2021. The survey was designed to collect demographic information, vaccination status, attitudes, beliefs, and anxiety about the vaccine, sources of information, and whether or not the participant watched an educational movie. The factors associated with beliefs and attitudes were analyzed using logistic and linear regression. A total of 4,062 valid questionnaires were retrieved. The positive vaccine behavior group included 3,725 students (91.7%). The most common source of information on the COVID-19 vaccine was TV/radio (75.0%), and the most common Social networking service (SNS) for COVID-19 information was Twitter (31.1%). Approximately 85% students believed in the efficacy of vaccination. Positive attitude was associated with female sex and watching an educational movie by the university. Concern about the vaccine was positively associated with information from acquaintances or Instagram, and negatively associated with information from Twitter, and watching the educational movie. The majority of students had positive beliefs and attitudes toward COVID-19 vaccination, and social media and educational movies produced by the university had a large influence on their attitude toward vaccination behavior. On the contrary, some students were anxious about vaccination. Promotion of educational movies on social media by the universities is an effective way to encourage vaccination among young people.

ObjectiveãAlthough volunteer activities of providing meals have been conducted as measures to prevent isolation and loneliness and to secure meals, evidence is lacking regarding how to implement such activities. In this study, we describe the activities process at a community cafeteria located within a housing complex and operated by resident volunteers during the COVID-19 pandemic to provide inexpensive meals. We also report the preliminary results of the impact of such activities on the residents.MethodãThis case study was conducted at the community cafeteria Tate Kitchen 'Sakura' located within a Tokyo housing complex with a high ageing population. We collected data on the cafeteria activities during February to May, 2020. The data sources were daily activity records of the cafeteria, dialogues between volunteers and residents, and photos of activities. We qualitatively assessed the effects of the activities on the residents by classifying interviews with ten users and six volunteer staff based on the Kawakita Jiro (KJ) method.ResultsãDuring the observation period, regular meetings were held among board members and volunteers, and operations of the cafeteria were verified and modified by referring to the COVID-19 prevention guide for citizens, advice from health professionals, and residents' opinions. It was determined that activities would continue without cessation; the cafeteria, managed mainly by volunteers under the food hygiene control system required for commercial restaurants, was open five days a week to maintain food security and ensure the health of the residents. The number of meals sold at the cafeteria was halved in May (n = 2,149) as a result of the modification in operations. However, the number of meals delivered to each household increased from March because of increased demand. Qualitative analyses using KJ method showed that users perceived that these continued activities were effective in securing food, maintaining social interaction and promoting health, and health promotion, while volunteers perceived that the activities were effective in promoting social interaction and health.ConclusionãThe resident volunteers continually confirmed their commitment to the principle of protecting food security and health within the community. They continued to operate the cafeteria by referring to available information on COVID-19 preventive measures, adopting the COVID-19 preventive measures, and involving all stakeholders. Qualitative analyses suggested that these continued efforts were useful for securing food and supporting health of the residents, looking after one other, and maintaining ties among residents.

OBJECTIVES: To clarify the association between moderate-to-vigorous physical activity (MVPA) and/or sedentary behaviour (SB) and the incidence of functional disability (FD) in older adults. DESIGN: Prospective cohort study. SETTING: Local municipality of Tsuru, Yamanashi, Japan. We conducted a baseline survey in January 2016. Follow-up was commenced on 1 February 2016 and completed on 31 October 2018. PARTICIPANTS: All individuals (6661 people) aged >65 years who were independently living in the community were eligible. METHODS AND OUTCOME MEASURES: MVPA (min/week) and SB (min/day) were measured using self-administered questionnaires in 5311 independently living older adults who participated in this study. The follow-up period was 33 months, and the incidence of FD was objectively determined by experts. The participants were divided into three groups based on MVPA distribution (non-MVPA, 0 min; short-MVPA, 1-299 min and long-MVPA, ≥300 min/week) and into two groups based on the median value of SB (short-SB,<190 min; and long-SB, ≥190 min/day). The participants were also classified into six categories based on different combinations of MVPA and SB. Cox proportional hazards model was used to calculate the HR and 95% CI for FD development with MVPA, SB and a combination of these behaviours. RESULTS: Among the included participants, 2415 were male and 2896 were female. The mean ages (SD) of the male and female participants were 74.5 (6.8) and 74.9 (6.9) years, respectively. The total number of participants with chronic conditions was 3489 (65.7%). Using the non-MVPA group as the reference, the multivariable-adjusted HR (95% CI) was 0.68 (0.54 to 0.84) in the short-MVPA group and 0.53 (0.41 to 0.69) in the long-MVPA group. Regarding SB, the short-SB group had an HR of 0.86 (0.71 to 1.03) compared with the long-SB group. The combined behaviour showed the lowest HR in the long-MVPA and short-SB group 0.49 (0.34 to 0.72) and the long-MVPA and long-SB group 0.49 (0.34 to 0.68), respectively. CONCLUSIONS: Long-MVPA had a robust association with FD development, whereas short-SB had a modest association. Moreover, a combination of these behaviours had a stronger association than individual behaviours. If the identified associations are assumed to be causal in nature, these findings suggest that encouraging older adults to engage in MVPA and reduce SB in their daily lives could be effective to prevent or delay FD development.

This study aimed to identify factors influencing the work engagement of employees working from home during the COVID-19 pandemic in Japan. Employees' work engagement was examined using the following survey questions: "Do you feel energized when you are at work? (yes or no)" and "Do you take pride in your work? (yes or no)" After adjusting for potential confounders, Poisson regression was used to examine prevalence ratio and 95% confidence intervals for employees' work engagement. We analyzed 15,670 individuals (11,894 of whom did not work from home and 3776 of whom worked from home). Their mean age was 45.6 ± 13.8 years, and 58.3% were men. Those who worked from home were younger than those who did not (43.9 ± 13.1 vs. 46.1 ± 13.9, p < 0.001). About 44% of all employees reported high work engagement. Among the employees who worked from home, an increase in sleep hours, effective interactions with supervisors, and working hours of ≤40 h/week were associated with engagement. Sensitivity analysis showed similar results. Close communication with superiors, refraining from working long hours, and obtaining adequate sleep may boost the work engagement of employees working from home.

BACKGROUND & AIMS: Fatty liver is associated with incident diabetes, and the fatty liver index (FLI) is a surrogate marker for non-alcoholic fatty liver disease (NAFLD). We aimed to determine whether or not FLI was associated with incident diabetes in relation to obesity and prediabetic levels in the general Japanese population. METHODS: This was a retrospective study using the Japanese health check-up database of one health insurance from FY2015 to FY2018. This study included 28,991 individuals with prediabetes. First, we stratified all participants into two groups: "high-risk," comprising patients with HbA1c >6.0%, and "standard," comprising the rest. Subsequently, we divided them into four groups according to FLI (<30 or not) and obesity (BMI <25 kg/m2 or not). Subsequently, the incidence rate of diabetes was compared among the groups after 3 years of follow-up using multiple logistic regression models after adjusting for potential confounders. RESULTS: After 3 years of follow-up, 1,547 new cases of diabetes were found, and the cumulative incidence was 2.96% for the standard group and 26.1% for the high-risk group. In non-obese individuals, odds ratios (95% confidence interval) for FLI ≥30 versus FLI <30 were: 1.44 (1.09-1.92) for the standard group and 1.42 (0.99-2.03) for the high-risk group. In the high-risk group, obesity (BMI ≥25 kg/m2) but FLI <30 was not a risk factor for developing diabetes. CONCLUSION: Although high FLI is generally considered to be a risk factor for developing diabetes, obesity might have been a confounding factor. However, the present study showed that high FLI is a risk factor for the development of diabetes, even in non-obese individuals. Our results include suggestion to develop a screening tool to effectively identify people at high risk of developing diabetes from the population (especially non-obese prediabetes) who are apparently at low health risk and are unlikely to be targeted for health guidance.

ObjectivesãThis study aims to develop a dietary consciousness scale and examine its reliability and validity, as well as investigate the changes in psychological aspects that influence diet among Japanese adults during the COVID-19 pandemic and clarify its related factors.MethodsãAn online survey was conducted from July 1, 2020 to July 3, 2020. Participants were adults aged between 20 and 69 years selected from 13 prefectures where the government declared the state of emergency from April to May 2020. All selected participants were shopping or cooking foods for more than 2 days a week at the time of the survey. A total of 2,299 participants were included in the analysis. Dietary consciousness was measured using 12 items, and the construct was examined using factor analysis. Cronbach's alpha was examined as an indicator of internal validity, and the criterion-referenced validity was confirmed using the Kruskal-Wallis test. To determine changes in dietary consciousness, we calculated total scores based on changes in each item of the Dietary Consciousness Scale as follows: no change (0 points), improved (+1 point), and worsening (-1 point). The associations between the changes in dietary consciousness and characteristics or socioeconomic factors of the participants were examined using the chi-squared test and residual analysis.ResultsãExploratory and confirmatory factor analyses demonstrated that a model consisting of two factors fitted the data (GFI = 0.958, AGFI = 0.938, CFI = 0.931, RMSEA = 0.066). Cronbach's alpha of the first factor (importance of diet) was 0.838 and 0.734 for the second factor (precedence of diet), and the reliability was confirmed at 0.828 for the entire scale. In the examination of criterion-related validity, the higher the stage of change, the higher the total score of the scale, and a significant difference was observed (P<0.001). The percentage of participants whose precedence worsened was higher than the importance. Significant differences were observed regarding gender, age group, marital status, employment status, household annual income, and income change during the COVID-19 pandemic considering changes in both the importance and precedence of diet. Those who were in the "worsening tendency" group in both the importance and precedence were men, 20-29 years old, unmarried, full-time employees, with a household income of 4-6 million yen during the past year.ConclusionãDuring the COVID-19 pandemic, the precedence of diet worsened, compared to its importance, and men, young, or unmarried persons show a worsening of dietary consciousness.

AIM: This study aims to examine the prevalence of postpartum depression and its relationship with social support adjusted for self-perceived impact of COVID-19 in parturient women admitted to a perinatal medical center in Japan. METHODS: This cross-sectional study included 513 women who underwent a 1-month postpartum checkup between August 3 and November 27, 2020. Postpartum depression was measured using the Edinburgh Postnatal Depression Scale. Social support was measured using the Multidimensional Scale of Perceived Social Support and the score was dichotomized using the Youden index. Nineteen demographic and obstetric characteristics were also assessed. RESULTS: Postpartum depression was observed in 35 (7.6%) of 461 women: 25 (26.6%) and 10 (2.7%) in the low- and high-support groups, respectively. Women in the low-support group were significantly more likely to have postpartum depression than those in the high-support group (odds ratio [OR], 11.7; 95% confidence interval [CI], 5.4-27.3; p < 0.001). Furthermore, no interaction was observed between social support and the impact of COVID-19 for postpartum depression (p = 0.32). CONCLUSIONS: The prevalence of postpartum depression in the study institution was lower than that reported by previous studies in Japan. Moreover, social support was an important predictive factor for postpartum depression during the COVID-19 pandemic.

BACKGROUND AND OBJECTIVES: This study evaluated the association of physical prefrailty with the prevalence of inadequate nutrients among community-dwelling Japanese elderly women. METHODS AND STUDY DESIGN: This cross-sectional study included 120 older women (age range, 65-79 years) at an elders college. Frailty was evaluated using the Japanese version of the Cardiovascular Health Study (J-CHS). Participants were classified as either prefrailty (1-2 deficits) or nonfrailty (0 deficits) based on set criteria. Both groups were compared in terms of physical function, exercise time, nutrient intake, and food group intake estimated by Food Frequency Questionnaire Based on Food Groups (FFQg), and estimated prevalence of inadequate nutrient intake, which was evaluated using each dietary reference value, set as the estimated average requirement (EAR) and dietary goal (DG), based on the Dietary Reference Intakes (DRIs) for Japanese, 2020. RESULTS: Of the participants, 45.0% exhibited physical prefrailty. Binary logistic regression analysis identified that vitamin C intake below EAR (OR, 7.12; 95% CI, 1.47-34.41, p=0.014) was the only factor associated with physical prefrailty. CONCLUSIONS: In addition to measuring physical function, dietary surveys and evaluation of nutritional adequacy by DRIs are expected to be useful for the early prevention of physical prefrailty by linking to nutrition education among community-dwelling Japanese elderly adults.

ObjectivesãThe aim of this study was to examine the effect of an exercise program targeting knee pain on longitudinal medical costs (MC) of elderly community-dwelling adults.MethodsãA community-based health program using specific exercises for improving knee pain was held from January to February, 2015. Twenty-eight individuals participated in the program (intervention group) and seventy individuals were selected from the respondents of a health and lifestyle survey by matching age, sex, and baseline value of severity of knee pain as a control group. Twenty individuals from the intervention group and twenty-nine from the control group were included in the final analysis. The changes in MC from 2014 to 2018 were compared between the two groups using a linear mixed-effects model.ResultsãThe effect of the program on MC, estimated as a change from the baseline in 2014, showed a reduction of -5.6×103 yen/person (95% CI: -39.2-28.0) for the entire four-year period after the intervention. However, this difference was not significant. The changes in MC each year after the intervention were 9.3×103 yen/person (95% CI: -39.6-58.3) in 2015, -2.0×103 yen/person (95% CI: -44.4-40.5) in 2016, -10.3×103 yen/person (95% CI: -42.5-21.9) in 2017, and 8.2×103 yen/person (95% CI: -39.1-55.4) in 2018.ConclusionãThe exercise program did not show a clear benefit in reducing the MC of elderly community-dwellers during the four years after the intervention. Further research with longer study durations and larger sample populations would be necessary to determine the effect of such intervention programs on MC.
