RESUMO
BACKGROUND: Although negative attitudes are known to develop with experiences of COVID-19 infection, it remains unclear whether such attitudes contribute to depression and anxiety as sequelae of COVID-19. We aimed to investigate the relationships between attitude towards COVID-19 infection and post-COVID-19 depression and anxiety. METHODS: A cross-sectional survey of COVID-19 recovered patients was conducted from July to September 2021 in Japan. Outcome variables, depression and anxiety were assessed using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7); scores of 10 and above were identified as having symptoms of depression and anxiety, respectively. Exposure variables were whether participants were experiencing the following attitude strongly: threat to life due to COVID-19 infection, helplessness regarding COVID-19 infection, blaming a third party who did not restrain from going outside, blaming themselves for their COVID-19 infection, worry about spreading the infection to others, and self-stigma (Self-Stigma Scale-Short). Modified Poisson regression analyses were performed to analyze the findings. RESULTS: A total of 6016 responses were included in the analyses. The proportion of depression was 19.88%, and anxiety was 11.47%. The threat of life due to COVID-19 infection, helplessness regarding COVID-19 infection, blaming oneself for their COVID-19 infection, and self-stigma were significantly associated with depression and anxiety after adjusting covariates. Blaming the third party who did not restrain from going outside was associated with anxiety. There was no association between the worry about spreading infection to others and depression or anxiety. CONCLUSION: Negative attitudes, including self-stigma with the experience of COVID-19 infection, were related to depression and anxiety. Further studies confirming whether countermeasures for preventing or decreasing the negative attitude towards COVID-19 infection mitigate these symptoms are needed.

BACKGROUND: Omega-3 polyunsaturated fatty acids (PUFAs) reduce depressive symptoms through an anti-inflammatory effect, and injection of both omega-3 PUFAs and estradiol (E2) induces antidepressant-like effects in rats by regulating the expression of inflammatory cytokines. The aims of this study were to examine the association of increased E2 during pregnancy with depressive symptoms and with inflammatory cytokines in women who were and were not supplemented with omega-3 PUFAs. METHODS: Pregnant women with Edinburgh Postnatal Depression Scale scores ≥9 were recruited at 12-24â¯weeks of gestation. The participants were randomly assigned to receive 1800â¯mg omega-3 fatty acids (containing 1206â¯mg eicosapentaenoic acid [EPA]) or placebo for 12â¯weeks. E2, omega-3 PUFAs, high-sensitivity C-reactive protein, interleukin-6, and adiponectin were measured at baseline and at the 12-week follow-up. Multivariable regression analyses were conducted to examine the association of the changes of E2 and omega-3 PUFAs with the changes in depressive symptoms and with the changes of inflammatory cytokines at follow-up by intervention group. RESULTS: Of the 108 participants in the trial, 100 (92.6%) completed the follow-up assessment including blood sampling. Multivariable regression analyses revealed that the increase of EPA and E2 was significantly associated with a decrease in depressive symptoms among the participants assigned to the omega-3 group, but not among those assigned to the placebo group. Neither E2 nor any PUFAs were associated with a change in inflammatory cytokines. CONCLUSION: Supplementation with EPA and increased levels of E2 during pregnancy might function together to alleviate antenatal depression through a mechanism other than anti-inflammation.

BACKGROUND: The number of psychiatric care beds and the mean length of stay in psychiatric care beds in Japan have decreased over the past 10 years. However, as has long been indicated here and elsewhere, Japan lags behind other countries in terms of deinstitutionalization. Furthermore, the population of inpatients in psychiatric care beds is aging dramatically. In addition to the diversification of mental illness, the question of what measures to implement going forward regarding current psychiatric bed resources has emerged as a new challenge. METHODS: Using data from the Patient Survey and the 630 Survey, we examined trends in the number of long-term inpatients in psychiatric care beds in Japan through 2040. Population estimation was used for estimating long-term hospital bed demand because of small fluctuations in the admission and discharge of long-term inpatients. RESULTS: In 2017, nearly one-third of all long-term hospitalized patients were aged ≥75 years, and an estimated 47% of the total are expected to die by 2040. Thus, the overall demand for long-term hospitalization is forecast to decrease sharply due to aging of currently hospitalized long-term inpatients. The number of long-term inpatients in 2017 was 167,579, and this is projected to decrease to 103,141 in 2040. CONCLUSIONS: We believe it is necessary to adopt a multifaceted approach to promote hospital discharge and transition to the community, and to address the diversification of mental illness and the issue of psychiatric care bed supply/availability, which are forecast to decrease due to the natural decrease in long-term inpatients.

OBJECTIVES: Although safe approaches for improving depression in pregnancy are required and the efficacy of omega-3 polyunsaturated fatty acids (PUFAs) has been suggested, the amount of supplemental omega-3 PUFAs has varied among previous studies and adequate amount might be different among countries. The aim of this pilot study is to explore the feasibility of using 1800â mg of omega-3 PUFAs supplementation for our future double-blind, placebo-control trial, and to clarify the clinical difference and the similarity between two sites of Japan and Taiwan. METHODS: Pregnant women between 12 and 24 weeks' gestation with depressive symptoms were recruited. Participants were supplemented daily with omega-3 PUFAs capsules containing 1206â mg eicosapentaenoic acid and 609â mg docosahexaenoic acid for 12 weeks. The primary outcome was change in total score on the 17-item Hamilton Rating Scale for Depression (HAMD) at 12 weeks after supplementation. RESULTS: Eight pregnant women in Japan and five in Taiwan participated in the study. A substantial proportion of pregnant women reported high consumption of omega-3 supplements and dietary fish were excluded in Taiwan rather than in Japan sites. The decrease in HAMD score from baseline to 12 weeks after the start of the intervention was significantly larger in Japanese participants than in Taiwanese participants (Wilcoxon rank sum test; Pâ =â 0.045). DISCUSSION: The improvement of depressive symptoms was smaller at the Taiwan site than at the Japan site. Differences in psychopathology of recruited participants identified by self-rating scales might affect the degree of population heterogeneity and the treatment efficacy. A randomized-controlled trial is needed to confirm these findings. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01948596.

AIM: Depression during pregnancy adversely affects both mother and child. As antenatal depression is a predictor of postnatal depression, early detection might prevent postnatal depression. The Edinburgh Postnatal Depression Scale (EPDS) is frequently used during the perinatal period, but the cut-off score during pregnancy has not been verified for the Japanese population. We aimed to clarify the optimal EPDS cut-off score in mid-pregnancy in Japan. METHODS: We recruited pregnant women aged 20 years or older at 12-24 gestational weeks and those who scored ≥9 on the EPDS were invited to participate in this study. In parallel with the EPDS, the Japanese version of the Mini-International Neuropsychiatric Interview was administered to determine diagnosis of major depressive episode. We then calculated the receiver-operator curve, sensitivity and specificity, and positive and negative predictive values for the EPDS. RESULTS: All 210 participants were in the second trimester except for one (12 gestational weeks). Twenty participants were diagnosed with major depressive episode. With a cut-off score set at 13 points, the area under the curve was 0.956; sensitivity and specificity were 90.0% and 92.1% [Correction added on 10 November 2017, after first online publication: The percentage for specificity has been corrected from 79.0% to 92.1%.], respectively; and positive and negative predictive values were 54.5% and 98.9%, respectively. CONCLUSION: To our knowledge, this is the first study to clarify the optimal EPDS cut-off score in the second trimester for Japan. This finding will be helpful for appropriate screening for antenatal depression in Japan.

BACKGROUND: Maternal depression can be harmful to both mothers and their children. Omega-3 polyunsaturated fatty acid (PUFA) supplementation has been investigated as an alternative intervention for pregnant women with depressive symptoms because of the supporting evidence from clinical trials in major depression, the safety advantage, and its anti-inflammatory and neuroplasticity effects. This study examines the efficacy of omega-3 PUFA supplementation for pregnant women with depressive symptoms in Taiwan and Japan, to provide evidence available for Asia. The rationale and protocol of this trial are reported here. METHODS: The Synchronized Trial on Expectant Mothers with Depressive Symptoms by Omega-3 PUFAs (SYNCHRO) is a multicenter, double-blind, parallel group, randomized controlled trial. Participants will be randomized to either the omega-3 PUFAs arm (1,200 mg eicosapentaenoic acid and 600 mg docosahexaenoic acid daily) or placebo arm. Primary outcome is total score on the Hamilton Rating Scale for Depression (HAMD) at 12 weeks after the start of the intervention. We will randomize 56 participants to have 90 % power to detect a 4.7-point difference in mean HAMD scores with omega-3 PUFAs compared with placebo. Because seafood consumption varies across countries and this may have a major effect on the efficacy of omega-3 PUFA supplementation, 56 participants will be recruited at each site in Taiwan and Japan, for a total number of 112 participants. Secondary outcomes include depressive symptoms at 1 month after childbirth, diagnosis of major depressive disorder, changes in omega-3 PUFAs concentrations and levels of biomarkers at baseline and at 12 weeks' follow-up, and standard obstetric outcomes. Data analyses will be by intention to treat. The trial was started in June 2014 and is scheduled to end in February 2018. DISCUSSION: The trial is expected to provide evidence that can contribute to promoting mental health among mothers and children in Asian populations. TRIAL REGISTRATION: Clinicaltrials.gov: NCT02166424 . Registered 15 June 2014; University Hospital Medical Information Network (UMIN) Center: UMIN000017979. Registered 20 May 2015.

Although cross-sectional studies have suggested that discrimination has a negative impact on the mental health of patients with COVID-19, no cohort studies with longitudinal data have established a causal relationship. Therefore, this study aimed to investigate the association between COVID-19-related discrimination and subsequent psychotic experiences in individuals who had contracted the disease. Secondary outcomes were PTSD symptoms, psychological distress, and suicidal ideation. We utilized inverse probability weighting and marginal structural models with robust standard errors to analyze the association, accounting for confounders and loss to follow-up. In a sensitivity analysis, we evaluated the robustness of the estimates to potential unmeasured confounding by analyzing E-values. Of 7760 participants who had contracted COVID-19, 5971 were included after excluding those with missing sociodemographic data. Of these, 1736 (29.1 %) reported experiencing COVID-19-related discrimination. Of the 2559 participants who completed the study, 253 (9.9 %) reported having at least one psychotic experience. Participants who reported experiencing any COVID-19-related discrimination showed a higher risk of subsequent psychotic experiences compared with participants without such discrimination (risk difference 6.6 %, 95 % CI 4.0 %-9.9 %; risk ratio 1.82, 95 % CI 1.42-2.47). A negative impact was also found in suicidal ideation, PTSD symptoms, and psychological distress. E-values demonstrated the robustness of some of the observed associations to unmeasured confounding. The study found that COVID-19-related discrimination was associated with subsequent psychotic experiences and other mental health outcomes in individuals who had contracted the disease. A study focusing on prevention strategies, such as an anti-discrimination campaign, is warranted.

Aim: This pilot examined the effect of online peer support on mental health problems among individuals with post-acute sequelae of COVID-2019 (PASC). Methods: A single-arm pre-post design of online peer-support design consisting of eight sessions of 1 h per week with three to six participants and two facilitators per group was performed. Participants were recruited from online communities, social media, and medical clinics for the PASC between May and August 2023. The degrees of depression, anxiety, loneliness, social withdrawal, and self-esteem were measured pre- and post-intervention. Participants' statements during the sessions were analyzed using thematic analyses. Results: Of the 18 participants, three dropped out of the interventions, and 17 (including two participants who dropped out) completed the pre- and post-intervention questionnaires. Depression severity significantly decreased in the paired t-test and linear mixed model. The following interactions were extracted: conveying the same feelings, dealing with difficulties, showing empathy, enhancing the atmosphere, and adapting to suit health conditions. Impressions extracted from participating in the interventions included feelings of emotional support, a sense of bonding, changes in perspective, changes in behaviors or new actions through participation, inadequacy during sessions, and adverse effects associated with participation. Conclusion: Online peer support may be helpful in treating depression in individuals with PASC.
RESUMO
Aim: The Mental Health Supporter Training Program is a national project conducted in Japan. This study aimed to determine the effects on mental health-related stigma, mental health literacy, and knowledge about mental health difficulties and support techniques among program participants. Methods: The target population was local residents of a wide range of generations in Japan. Outcomes were assessed at baseline (T1), immediately postintervention (T2), and at the 6-month follow-up (T3). A mixed model for repeated-measures conditional growth model analyses were employed to examine the effects of the intervention over time (T1, T2, T3). We also calculated effect sizes using Cohen's d. Results: The program had a significantly favorable pooled effect on the Japanese version of the Reported and Intended Behaviour Scale score after adjusting for covariates (reported behavior [t = 3.20, p = 0.001]; intended behavior [t = 8.04, p < 0.001]). However, when compared at each time point, only intended behavior from T1 to T2 showed a significant difference (t = 8.37, p < 0.001). Significant pooled effects were found for mental health literacy (knowledge: t = 19.85, p < 0.001; attitude: t = 15.02, p < 0.001), knowledge of mental health (t = 28.04, p < 0.001), and psychological distress (t = -2.41, p = 0.016). Conclusion: The results suggest that the program might be effective for improving intended, but not reported, behavior in the short term and for improving mental health literacy, knowledge of mental health, and psychological distress.

Evidence demonstrating the association of preexisting psychiatric disorders with post-COVID-19 is limited. We aim to investigate the association using larger sample sizes and more extended postinfection periods than previous studies. A total of 6015 (response rate = 77.5%) COVID-19 survivors were surveyed using a self-administered questionnaire from July to September 2021. Poisson regression analysis with robust error variance was performed to estimate post-COVID-19 prevalence ratios (PRs) with or without preexisting psychiatric disorders. Participants with preexisting psychiatric disorders numbered 1067 (17.7%), and with post-COVID-19 were 2149 (35.7%). Post-COVID-19 PR with preexisting psychiatric disorders was 1.09 (95% CI 1.02-1.18, p = 0.013). The interaction between preexisting psychiatric disorders and postinfection periods was significant (p for interaction < 0.001). The subgroup analysis showed that those with preexisting psychiatric disorders might be at greater prolonged risk of post-COVID-19 than those without the disorders. These findings suggested that preexisting psychiatric disorders were associated with an increased post-COVID-19 risk, and post-COVID-19 with preexisting psychiatric disorders might prolong even if time passes.

The psychological distress experienced by coronavirus disease of 2019 (COVID-19) survivors after recovery from the illness is amplified by discrimination endured because of their infection status. However, the difference in the risk of facing discrimination and risk of experiencing psychological distress in the early and late waves of the COVID-19 pandemic remain unclear. This study aimed to investigate whether the risk of facing discrimination because of infection status was lower in the early or late waves and whether risk of discrimination on psychological distress was more serious in later, rather than earlier waves. We conducted two online surveys to collect data from survivors divided into two groups. The participants with scores of five or more on the Kessler Psychological Distress Scale were identified as having experienced psychological distress. The participants were identified as having experienced discrimination based on infection status if they had endured being blamed, some type of discrimination, or having themselves or their families maligned. The timing of infection was split into infected during early waves of the pandemic for 2021 participants and infected during later waves of the pandemic for 2022 participants. Modified Poisson regression analyses were performed using experiences of discrimination as criteria and timing of infection as predictors. Modified Poisson regression analyses were further performed using the presence of psychological distress as a criteria and experiences of discrimination and timing of infection as the criteria, in addition to interaction effect of these es. The data of 6010 participants who were infected in early waves and 5344 participants who were infected in later waves were analyzed. The risks of being blamed, some forms of discrimination, and participants and their families being maligned were significantly lower in the group who were infected in later waves than those infected in earlier waves. Experiences of discrimination were highly associated with psychological distress in those infected in later waves than those infected in earlier waves, while only being blamed showed a significant association. Risk of discrimination was found to be lower in those infected in later waves, whereas risk of discrimination on psychological distress was shown to be more serious in those infected in later waves. Therefore, we submit that it is more important to support COVID-19 survivors who face discrimination, than it is to attempt to decrease the current discriminatory climate caused by the COVID-19 pandemic.

Aim: We aimed to illustrate and compare the processes of mental health policies aiming at a service delivery shift from the hospital to the community using implementation science, and to identify important implementation strategies. Methods: This study had a comparative case study design. The cases were the Belgian mental health reform, and the person-centered model of mental health in Hong Kong, China. Several documentary sources were reviewed, including the published literature and websites. Data on policy processes were extracted, analyzed using directed content analysis, and categorized into constructs of the conceptual model for evidence-informed policy formulation and implementation arranged for the mental health policy. Results: Several similarities were identified in the strategies for active implementation and dissemination; official staff allocation, and training to the community psychiatric services, an approach to adjust the number of psychiatric hospital beds, and promoting collaboration between health care sectors and social welfare sectors. Under distinct social contexts, differences were found in all processes. Conclusions: Each of the described policy processes can serve as a model for countries in similar social contexts seeking to shift their psychiatric service delivery. Furthermore, our findings suggest widely applicable implementation strategies for policies aiming at a service delivery shift.
RESUMO
Background: Health insurance claims data are used in various research fields; however, an overview on how they are used in healthcare research is scarce in Japan. Therefore, we conducted a scoping review to systematically map the relevant studies using Japanese claims data. Methods: MEDLINE, EMBASE, and Ichushi-Web were searched up to April 2021 for studies using Japanese healthcare claims data. We abstracted the data on study characteristics and summarized target diseases and research themes by the types of claims database. Moreover, we described the results of studies that aimed to compare health insurance claims data with other data sources narratively. Results: A total of 1,493 studies were included. Overall, the most common disease classifications were "Diseases of the circulatory system" (18.8%, n = 281), "Endocrine, nutritional, and metabolic diseases" (11.5%, n = 171; mostly diabetes), and "Neoplasms" (10.9%, n = 162), and the most common research themes were "medical treatment status" (30.0%, n = 448), "intervention effect" (29.9%, n = 447), and "clinical epidemiology, course of diseases" (27.9%, n = 417). Frequent diseases and themes varied by type of claims databases. A total of 19 studies aimed to assess the validity of the claims-based definition, and 21 aimed to compare the results of claims data with other data sources. Most studies that assessed the validity of claims data compared to medical records were hospital-based, with a small number of institutions. Conclusions: Claims data are used in various research areas and will increasingly provide important evidence for healthcare policy in Japan. It is important to use previous claims database studies and share information on methodology among researchers, including validation studies, while informing policymakers about the applicability of claims data for healthcare planning and management.
RESUMO
BACKGROUND: This study aimed to examine the course of depression and anxiety in COVID-19 survivors with a psychiatric history compared with those without a psychiatric history. METHODS: A web-based cross-sectional survey for COVID-19 survivors was conducted from July to September 2021. A total of 6016 COVID-19 survivors, the accuracy of whose responses was determined to be assured, were included in analyses. Exposures included psychiatric history and time since COVID-19 infection, and the main outcomes and measures included severity of depression and anxiety, as assessed using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7), respectively. RESULTS: Mean severity of PHQ-9 and GAD-7 were significantly higher in participants with a psychiatric history than in those without a psychiatric history. Two-way analysis of covariance for PHQ-9 showed a significant main effect of the presence of psychiatric history and a significant interaction effect of psychiatric history × time since infection. Two-way analysis of covariance for the GAD-7 score revealed a significant main effect of the presence of psychiatric history and time since COVID-19 infection and the interaction effect of these factors. CONCLUSIONS: The course of depression and anxiety was more severe in COVID-19 survivors with a psychiatric history than in those without a psychiatric history.

Evidence is mixed on the associations between physical activity during pregnancy and perinatal depression, and it is limited for different physical activity intensities. Data for 92,743 pregnant women from the Japan Environment and Children's Study were analyzed in this study. Psychological distress during pregnancy was assessed as moderate or severe using the Kessler Psychological Distress Scale (K6 5-12 and ≥13, respectively). Postpartum depression was assessed using the Edinburgh Postpartum Depression Scale (EPDS; cut-off score 9). Women with only light physical activity had significantly lower odds of psychological distress during pregnancy than those with no physical activity (K6 5-12: adjusted odds ratio [AOR] 0.86, 95% confidence interval [95%CI] 0.82, 0.90; K6 ≥ 13: AOR 0.64, 95%CI 0.58, 0.72). Women with a combination of light, moderate and vigorous physical activity had significantly higher odds of psychological distress during pregnancy (K6 5-12: AOR 1.32, 95%CI 1.18, 1.48; K6 ≥ 13: AOR 1.45, 95%CI 1.16, 1.81) and depression after childbirth (EPDS ≥ 9: AOR 1.42, 95%CI 1.24, 1.61). Physical activity intensity should be considered when assessing psychological distress risk during pregnancy and depression risk after delivery. Future research should evaluate specific physical activity programs with optimal intensity for pregnant women to prevent and treat their psychological distress and depression.

BACKGROUND: Little is known regarding trends of psychological distress and use of mental health services in Japan during recent years. METHODS: This study examined trends in severe and moderate psychological distress and the use of mental health services among adults (≥18 years old), using the Comprehensive Survey of Living Conditions in Japan from 2007, 2010, 2013, and 2016 (Total Nâ¯=â¯2,159,005, all survey years combined). We defined a score of ≥13 on Kessler Psychological Distress Scale (K6) as severe distress and a K6 score between 5 and 12 as moderate distress. Age- and sex-specific trends of psychological distress and the use of mental health services were also examined. RESULTS: As compared with 2007, those with severe distress slightly increased in 2016 (4.01%-4.15%, pâ¯=â¯0.02) while those with moderate distress remained mostly unchanged (24.61%-24.69%, pâ¯=â¯0.61). The use of mental health services steadily increased in this decade for both with severe distress (11.95%-15.76%, pâ¯<â¯0.01) and with moderate distress (2.60%-3.56%, pâ¯<â¯0.01). The prevalence of severe distress among women aged 25-29 years old was highest in 2016 among all the age groups although the use of mental health services was not particularly high among women in this age group. LIMITATIONS: Cross-sectional nature of the data did not allow us to examine the causal relationship between psychological distress and the use of mental health services. CONCLUSIONS: In spite of an observed increase in the use of mental health services, the prevalence of psychological distress slightly increased. Further studies are necessary to identify sources of treatment gap especially for vulnerable demographic subgroups.
