ABSTRACT
OBJECTIVE: Insomnia disorder is a global public health issue, commonly treated with hypnotics. However, long-term use of benzodiazepine derivatives (BZDs), especially polypharmacy with this kind of drug, carries risks for dependence and abuse. This study using large-scale medical insurance records investigated the causes of polypharmacy through the treatment of insomnia disorder. METHODS: A cross-sectional study analyzed anonymized medical record data from July 2014 to March 2018 provided by a nationwide Japanese health insurance association covering 405,952 individuals. Outpatients prescribed at least one sleep medication were included. Demographic data, pharmacological classification of the drugs, and comorbidities were assessed using hierarchical logistic regression analysis to explore their associations with polypharmacy. RESULTS: Of the 33,212 outpatients who were prescribed sleep medications, 32.5 % were prescribed multiple types. After adjusting for demographics and type of sleep medications as covariates, hypnotic polypharmacy was significantly associated with younger age, the presence of certain kinds of comorbidities, and using BZD anxiolytics before bedtime with the highest adjusted odds ratios (8.01-9.39) when referenced with BZD hypnotics. On the other hand, usage of orexin receptor antagonists, melatonin receptor agonists, and Z-drugs indicated lower odds ratios (0.74-0.87). CONCLUSIONS: Hypnotic polypharmacy is relatively common in the Japanese general population. With the introduction of non-pharmacological therapy in mind, assessing patients' comorbidities and avoiding the use of benzodiazepines, especially BZD anxiolytics, before bedtime would be recommended to prevent polypharmacy.
ABSTRACT
BACKGROUND: Previously, we demonstrated that childhood maltreatment could worsen depressive symptoms through neuroticism. On the one hand, some studies report that sleep disturbances are related to childhood maltreatment and neuroticism and worsens depressive symptoms. But, to our knowledge, no reports to date have shown the interrelatedness between childhood maltreatment, neuroticism, and depressive symptoms, and sleep disturbance in the one model. We hypothesized that sleep disturbance enhances the influence of maltreatment victimization in childhood or neuroticism on adulthood depressive symptoms and the mediation influence of neuroticism between maltreatment victimization in childhood and adulthood depressive symptoms. SUBJECTS AND METHODS: Total 584 Japanese volunteer adults recruited through convenience sampling from 4/2017 to 4/2018 were assessed regarding their characteristics of demographics, history of childhood maltreatment, sleep disturbance, neuroticism, and depressive symptoms with questionnaires self-administered. Survey data were analyzed using simple moderation models and a moderating mediation model. RESULTS: The interaction of sleep disturbance with childhood maltreatment or neuroticism on depressive symptoms was significantly positive. Furthermore, the moderating effect of sleep disturbance on the indirect effect of childhood maltreatment to depressive symptoms through neuroticism was significantly positive. LIMITATIONS: Because this was a cross-sectional study, a causal relationship could not be confirmed. CONCLUSIONS: Our findings indicate that individuals with milder sleep disturbance experience fewer depressive symptoms attributable to neuroticism and childhood maltreatment. Additionally, people with less sleep disturbance have fewer depressive symptoms arising from neuroticism owing to childhood maltreatment. Therefore, improvement of sleep disturbance will buffer the aggravating effect of childhood maltreatment, neuroticism caused by various factors, and neuroticism resulting from childhood maltreatment on depressive symptoms.

BACKGROUND: It is unclear how primary care physicians manage insomnia after the introduction of novel hypnotics such as orexin receptor antagonists and melatonin receptor agonists. This Web-based questionnaire survey aimed to examine treatment strategies for insomnia in Japanese primary care practice. METHODS: One-hundred-and-seventeen primary care physicians were surveyed on the familiarity of each management option for insomnia on a binary response scale (0 = "unfamiliar"; 1 = "familiar") and how they managed insomnia using a nine-point Likert scale (1 = "I never prescribe/perform it"; 9 = "I often prescribe/perform it"). Physicians who were unfamiliar with a management option were deemed to have never prescribed or performed it. RESULTS: Regarding medication, most physicians were familiar with novel hypnotics. Suvorexant was the most used hypnotic, followed by lemborexant and ramelteon. These novel hypnotics averaged 4.8-5.4 points and 4.0-4.7 points for sleep onset and sleep maintenance insomnia, respectively. By contrast, most benzodiazepines were seldom used below two points. Regarding psychotherapy, only approximately 40% of the physicians were familiar with cognitive behavioral therapy for insomnia (CBT-I) and they rarely implemented it, at an average of 1.5-1.6 points. More physicians were familiar with single-component psychotherapies (i.e., relaxation, sleep restriction therapy, and stimulus control) compared to CBT-I, and 48-74% of them implemented it slightly more often, with scores ranging from 2.6 to 3.4 points. CONCLUSION: This study suggests that Japanese primary care physicians seldom use CBT-I to treat insomnia. In addition, they use novel sleep medications more frequently than benzodiazepines in terms of pharmacotherapy. The use and availability of CBT-I in Japanese primary care might be facilitated by: educating primary care physicians, implementing brief or digital CBT-I, and/or developing collaborations between primary care physicians and CBT-I specialists.

AIM: The risk of falls owing to simultaneous use of multiple hypnotics has not been clarified. The aim of this study was to assess the association between the simultaneous use of 2 hypnotics and the occurrence of falls in hospitalized patients. METHODS: A matched case-control study was conducted at Tokyo Medical University Hospital in Tokyo, Japan, utilizing data from medical records. Cases were 434 hospitalized patients who experienced falls during their hospital stay between January 2016 and December 2016, and controls were 434 hospitalized patients without falls, individually matched by age, sex, and clinical department. The outcome was the occurrence of an in-hospital fall. The associations between the use of 1 hypnotic and falls, and between the use of 2 hypnotics and falls were assessed by conditional logistic regression analyses. The main multivariable conditional logistic regression model was adjusted for potential risk factors, including the use of other classes of psychotropics (antipsychotics, antidepressants, and anxiolytics), in addition to patient characteristics. RESULTS: The main multivariable conditional logistic regression analyses showed that the simultaneous use of 2 hypnotics (odds ratio [OR] = 2.986; 95% confidence interval [CI], 1.041-8.567), but not the use of a single hypnotic (OR = 1.252; 95% CI, 0.843-1.859), was significantly associated with an increased OR of falls. CONCLUSION: The simultaneous use of 2 hypnotics is a risk factor for falls among hospitalized patients, whereas the use of a single hypnotic may not.

BACKGROUND: Previous studies reported that the experience of maltreatment in childhood reduces subjective well-being in adulthood and that neuroticism is negatively associated with subjective well-being. However, the interrelationship between childhood maltreatment, adult life events, neuroticism, and subjective well-being has not been analyzed to date. METHODS: A total of 404 adult volunteers provided responses to the following questionnaires: 1) Childhood Abuse and Trauma Scale, 2) Life Experiences Survey, 3) Neuroticism Subscale of the Shortened Eysenck Personality Questionnaire-Revised, and 4) Subjective Well-Being Inventory. The path model was used to analyze possible interrelationships among these parameters. RESULTS: The effect of childhood abuse on subjective well-being was indirect and was mediated by neuroticism. The effect of neuroticism on the negative, but not positive, change score on the Life Experiences Survey was significant. The indirect effect of neuroticism on subjective well-being was not significant via either negative or positive change scores. CONCLUSIONS: This study demonstrated that age, subjective social status, neuroticism, and negative and positive life events were significantly associated with subjective well-being. Furthermore, using path analysis, we demonstrated the mediating role of neuroticism in the indirect effect of childhood abuse on subjective well-being.
ABSTRACT
BACKGROUND: Personality traits, such as neuroticism, that results in vulnerability to stress, and resilience, a measure of stress coping, are closely associated with the onset of depressive symptoms, whereas regular physical activity habits have been shown to reduce depressive symptoms. In this study, the mediating effects of neuroticism and resilience between physical activity duration and depressive symptoms were investigated by a covariance structure analysis. METHODS: Between April 2017 and April 2018, 526 adult volunteers were surveyed using self-administered questionnaires. Demographic information, habitual physical activity duration (PAD), neuroticism, and resilience were investigated. The effects of these factors on depressive symptoms were analyzed by a covariance structure analysis. This study was conducted with the approval of the Medical Ethics Committee of Tokyo Medical University. RESULTS: The dose-response curves of physical activity duration and depression scores were U-shaped: the optimal physical activity duration for the lowest depression score was 25.7 h/week. We found that the greater the difference from the optimal PAD, the higher the neuroticism and the lower the resilience, and the more severe the depressive symptoms. Covariance structure analysis demonstrated that neuroticism and resilience significantly and completely mediated the effects of the difference from the optimal PAD on depressive symptoms (coefficient of determination R2 = 0.349). CONCLUSION: Our study suggests that there is an optimal PAD that reduces depressive symptoms, and that a greater difference from the optimal PAD increases depressive symptoms through neuroticism and resilience.
ABSTRACT
Delayed sleep-wake phase disorder (DSWPD) is a sleep disorder in which the habitual sleep-wake timing is delayed, resulting in difficulty in falling asleep and waking up at the desired time. Patients with DSWPD frequently experience fatigue, impaired concentration, sleep deprivation during weekdays, and problems of absenteeism, which may be further complicated by depressive symptoms. DSWPD is typically prevalent during adolescence and young adulthood. Although there are no studies comparing internationally, the prevalence of DSWPD is estimated to be approximately 3% with little racial differences between Caucasians and Asians. The presence of this disorder is associated with various physiological, genetic and psychological as well as behavioral factors. Furthermore, social factors are also involved in the mechanism of DSWPD. Recently, delayed sleep phase and prolonged sleep duration in the young generation have been reported during the period of COVID-19 pandemic-related behavioral restrictions. This phenomenon raises a concern about the risk of a mismatch between their sleep-wake phase and social life that may lead to the development of DSWPD after the removal of these restrictions. Although the typical feature of DSWPD is a delay in circadian rhythms, individuals with DSWPD without having misalignment of objectively measured circadian rhythm markers account for approximately 40% of the cases, wherein the psychological and behavioral characteristics of young people, such as truancy and academic or social troubles, are largely involved in the mechanism of this disorder. Recent studies have shown that DSWPD is frequently comorbid with psychiatric disorders, particularly mood and neurodevelopmental disorders, both of which have a bidirectional association with the pathophysiology of DSWPD. Additionally, patients with DSWPD have a strong tendency toward neuroticism and anxiety, which may result in the aggravation of insomnia symptoms. Therefore, future studies should address the effectiveness of cognitive-behavioral approaches in addition to chronobiological approaches in the treatment of DSWPD.
ABSTRACT
Purpose: There is a lack of evidence regarding answers for clinical questions about treating insomnia disorder. This study aimed to answer the following clinical questions: (1) how to use each hypnotic and non-pharmacological treatment differently depending on clinical situations and (2) how to reduce or stop benzodiazepine hypnotics using alternative pharmacological and non-pharmacological treatments. Methods: Experts were asked to evaluate treatment choices based on 10 clinical questions about insomnia disorder using a nine-point Likert scale (1 = "disagree" to 9 = "agree"). The responses of 196 experts were collected, and the answers were categorized into first-, second-, and third-line recommendations. Results: The primary pharmacological treatment, lemborexant (7.3 ± 2.0), was categorized as a first-line recommendation for sleep initiation insomnia, and lemborexant (7.3 ± 1.8) and suvorexant (6.8 ± 1.8) were categorized as the first-line recommendations for sleep maintenance insomnia. Regarding non-pharmacological treatments for primary treatment, sleep hygiene education was categorized as the first-line recommendation for both sleep initiation (8.4 ± 1.1) and maintenance insomnia (8.1 ± 1.5), while multicomponent cognitive behavioral therapy for insomnia was categorized as the second-line treatment for both sleep initiation (5.6 ± 2.3) and maintenance insomnia (5.7 ± 2.4). When reducing or discontinuing benzodiazepine hypnotics by switching to other medications, lemborexant (7.5 ± 1.8) and suvorexant (6.9 ± 1.9) were categorized as first-line recommendations. Conclusion: Expert consensus indicates that orexin receptor antagonists and sleep hygiene education are recommended as first-line treatments in most clinical situations to treat insomnia disorder.
ABSTRACT
BACKGROUND: Previous studies have reported that physical activity can prevent the onset of depression and reduces anxiety. In the present study, the hypothesis that total physical activity time influences depressive symptoms via state and trait anxiety was tested by a path analysis. METHODS: Self-administered questionnaires were used to survey 526 general adult volunteers from April 2017 to April 2018. Demographic information, physical activity, and state and trait anxiety were investigated. RESULTS: The association between physical activity time and depressive symptoms was expressed as a U-shape curve. The results of the covariance structure analysis showed that differences from the optimal physical activity time (DOT) had direct positive effects on state and trait anxiety. DOT affected depressive symptoms only via trait anxiety, and this was a complete mediation model. CONCLUSION: The present study suggests that an optimal physical activity time exists for depressive symptoms. The path model demonstrated an association between the three factors of optimal physical activity time, trait anxiety, and depressive symptoms, and the effect was fully mediated by trait anxiety.

Delayed sleep-wake phase disorder (DSWPD) is a common circadian sleep-wake phase disorders brings serious social impairment of the patients. Melatonin is the main medication option; however, it has not been approved in some countries, and over-the-counter melatonin is under poor quality control. The melatonin receptor agonist ramelteon might be a potential treatment option, but there are few reports regarding its use in DSWPD patients. Existing pharmacological and chronobiological studies suggest that an ultra-low dose of ramelteon in the early night is beneficial for DSWPD. Here, we present our clinical experience together with a pharmacological review and discussion. Twenty-three DSWPD patients, of whom 18 patients had a treatment history of a normal dose of ramelteon, were prescribed low-dose ramelteon (median: 0.571 mg, 1/14 of a tablet) to be taken in the early night (mean: 18:10). After the treatment, the mean sleep schedule was significantly advanced, and clinical symptoms were improved. CITATION: Shimura A, Kanno T, Inoue T.

BACKGROUND: Long working hours are detrimental to physical and mental health. However, the association between long working hours and psychosomatic symptoms have remained controversial, possibly because of the existence of mediators between working hours and psychosomatic stress responses. We hypothesized that lifestyle habits, regarding sleep and mealtimes, act as mediators, and analyzed the associations between long working hours, sleep duration, mealtime regularity, and psychosomatic stress responses in office workers. METHODS: From April 2017 to March 2018, an online cross-sectional survey regarding overtime work hours, work-related stress, sleep, and eating habits was conducted with employees of 17 companies located in Tokyo, Japan. Answers were obtained from 3559 employees, and 3100 provided written consent for the academic use of their answers, and were included in the analysis. A path analysis was conducted to assess the effect of overtime work on psychosomatic stress via shortened sleep or irregular mealtimes. RESULTS: Overtime work hours had no direct effect on psychosomatic stress responses and depressive symptoms. However, overtime work hours affected sleep duration and the regularity of mealtimes. The effects of overtime work hours on psychosomatic stress responses and depressive symptoms were completely mediated by sleep duration and the regularity of mealtimes. CONCLUSION: Long working hours do not affect mental health directly; however, shortened sleep duration and irregular mealtimes mediate the effect of long working hours on psychosomatic stress responses and depressive symptoms.

Purpose: Depression poses a substantial burden worldwide. Therefore, elucidating the pathophysiological mechanism of depression is important. Sleep disturbance and sleep reactivity are symptoms of depression and are also known to exacerbate depressive symptoms. On the other hand, it is well known that resilience ameliorates depressive symptoms. To our knowledge, there have been no reports to date regarding the interaction effects among sleep disturbance, sleep reactivity, and resilience on depressive symptoms. We hypothesized that resilience buffers the aggravating effects of sleep disturbance and sleep reactivity on depressive symptoms. To test this hypothesis, we conducted hierarchical multiple regression analyses. Subjects and Methods: A total of 584 Japanese adult volunteers were recruited between April 2017 and April 2018 by convenience sampling. Their demographic characteristics, sleep disturbance, sleep reactivity, resilience, and depressive symptoms were investigated using self-administered questionnaires. The data were analyzed using hierarchical multiple regression analyses. Results: Sleep disturbance and sleep reactivity were significantly positively associated with depressive symptoms, whereas resilience was significantly negatively associated with depressive symptoms. Moreover, there was a significant interaction between sleep disturbance or sleep reactivity and resilience on depressive symptoms. Resilience significantly alleviated the aggravating effect of sleep disturbance and sleep reactivity on depressive symptoms. Conclusion: Our results indicate that people with lower resilience have more severe depressive symptoms that are associated with sleep disturbance and sleep reactivity. Therefore, there is a possibility that the enhancement of resilience will buffer the aggravating effects of sleep disturbance and sleep reactivity on depressive symptoms, and that improving sleep quality might alleviate the negative effect of low resilience on depressive symptoms.
ABSTRACT
INTRODUCTION: Misalignment of chronotype and social schedules result in sleep and health impairments. Presenteeism, the work productivity loss caused by health problems, has much more social costs than absenteeism and is associated with sleep disturbance. However, little is known about the link between chronotype and presenteeism. In this study, the associations between chronotype, sleep schedules, presenteeism, and the mediating role of sleep disturbance were examined. METHODS: A cross-sectional survey was conducted on 8155 office workers from 42 companies in Japan, from 2017 to 2019. The participants answered self-administered questionnaires asking about presenteeism (Work Limitations Questionnaire [WLQ]), sleep disturbance (Pittsburgh Sleep Quality Index [PSQI]), and habitual sleep schedules which enable to calculate the midpoint of sleep on free days, sleep corrected (MSFsc). The mediating effect was examined by using structural equation modeling (SEM). RESULTS: The participants comprised 4462 males and 3677 females (mean age: 36.7 years), and their mean productivity loss was 5.97%. A later sleep onset (+0.29%/h), early wakeup (+0.14%/h), and eveningness (+0.27%/h, MSFsc) were associated with presenteeism in all participants; however, the effect size and significance differed depending on their chronotype. SEM demonstrated a complete mediation model between chronotype and presenteeism, mediated by sleep disturbance and adjusted by age. CONCLUSIONS: Chronotype did not directly, but indirectly affected presenteeism through sleep disturbance. Eveningness leads to sleep disturbance, which then causes presenteeism. On workdays, early sleep times for morningness people, and late wakeup times for eveningness people may improve their work productivity.

BACKGROUND: Childhood parental bonding and cognitive complaints (CCs) affect a worker's mental health (MH), and CCs affect presenteeism. However, the impact of childhood parental bonding on presenteeism and the mediating effect of CCs with respect to the association among childhood parental bonding and presenteeism remain poorly understood. AIM: We aimed to investigate the mediating role of CCs on the relationship between childhood parental bonding and presenteeism to better understand the influence of childhood parental bonding on adulthood presenteeism. SETTING: A total of 440 Japanese adult workers recruited using convenience sampling were evaluated. METHODS: The Parental Bonding Instrument, Cognitive Complaints in Bipolar Disorder Rating Assessment and Work Limitations Questionnaire 8 were used to assess childhood parental bonding, CCs, and presenteeism, respectively. We performed Spearman's correlation analysis and path analysis to investigate the relationship among the variables. RESULTS: Path analysis revealed that childhood parental bonding and CCs significantly affected presenteeism. More specifically, CCs fully and partially mediated the effect of paternal and maternal care on presenteeism, respectively. Moreover, CCs partially mediated the effects of both paternal and maternal overprotection on presenteeism. CONCLUSION: The mediating role of CCs on the relationship between childhood parental bonding and presenteeism was shown in this study. In occupational MH, evaluating the mediating effect of CCs may be useful for addressing adulthood presenteeism associated with childhood parental bonding.

BACKGROUND: Sleep disturbance, state anxiety, and cognitive complaints (CCs) have been recognized as important issues in public health. Although the mediating role of CCs has been proposed, their role in the relationships between sleep disturbance, state anxiety, and subjective well-being (SWB) and subjective ill-being (SIB) are not yet fully understood. This study used path analyses to investigate whether CCs mediate these relationships. METHODS: The study recruited 523 Japanese adult volunteers using convenience sampling. Participants completed the Pittsburgh Sleep Quality Index, State-Trait Anxiety Inventory (Form Y), Cognitive Complaints in Bipolar Disorder Rating Assessment, and Subjective Well-Being Inventory to evaluate sleep disturbance, state anxiety, CCs, and SWB and SIB, respectively. Path analyses were conducted to assess the mediating effects of CCs. RESULTS: The path analyses showed significant indirect associations of sleep disturbance and state anxiety with SWB (p = 0.024 and p = 0.012) and SIB (p < 0.001 and p < 0.001), respectively, mediated by CCs. Furthermore, there were significant indirect associations of sleep disturbance with CCs (p < 0.001), SWB (p < 0.001), and SIB (p < 0.001), via state anxiety, respectively. CONCLUSIONS: This study suggests that CCs mediate the associations of sleep disturbance and state anxiety with SWB and SIB, respectively, in adult community volunteers. To address SWB and SIB associated with sleep disturbance and state anxiety, evaluating CCs may be useful in public mental health. Our findings will encourage health care workers to assess CCs more systematically. Future studies may need to target CCs to develop interventions for SWB and SIB.

BACKGROUND: Victimization in childhood profoundly influences the mental health of individuals in adulthood, causing depression, anxiety disorder, suicidality, and self-harm, which leads to productivity loss in the workplace, ie, presenteeism. However, the specific effects of victimization on presenteeism remain unclear. We hypothesized that victimization affects the presenteeism of workers through neuroticism and perceived job stressors and analyzed the association among these factors by path analysis. METHODS: A questionnaire survey, including demographic and clinical data, Japanese versions of victimization scale in childhood, Brief Job Stress Questionnaire, and Work Limitations Questionnaire (WLQ), was administered to 443 adult volunteers between April 2017 and April 2018 in Tokyo, Japan. Multiple variables were analyzed by multiple regression analysis and path analysis. The Institutional Review Board of Tokyo Medical University approved this study. RESULTS: Path analysis demonstrated that neuroticism and perceived job stressors had direct effects on presenteeism in the WLQ. Victimization indirectly increased presenteeism via neuroticism and its subsequent effects on perceived job stressors. This model accounted for 18% of the variability of presenteeism (R 2 = 0.180). LIMITATIONS: There may be possible recall bias owing to the self-administration of the questionnaire. In addition, this study had a cross-sectional design, and hence the causal associations among variables should be validated in a prospective study. CONCLUSION: The present study indicates that the experience of victimization in childhood is a risk factor of adulthood presenteeism, and this effect is mediated by neuroticism and adverse effects on job stressors. These results suggest that multiple factors, including childhood victimization, neuroticism, and job stressors, should be considered when assessing and preventing presenteeism.
ABSTRACT
AIM: Several studies have suggested the use of psychotropics as a possible risk factor for falling. However, there were several limitations to these previous studies, such as the use of data obtained from administrative databases and the lack of information about the time interval between psychotropics use and falling. Therefore, in this study, we aimed to assess the association between psychotropics use and falling in hospitalized patients, using reliable data collected from medical records. METHODS: A matched (age, sex, and inpatient department) case-control study of patients hospitalized at Tokyo Medical University Hospital was performed using the new-user design, based on data extracted from medical records. The outcome was the occurrence of falls. The use of four classes of psychotropics (antipsychotics, antidepressants, anxiolytics, and hypnotics) was compared between 254 cases (patients who experienced falls) and 254 controls (patients without falls). Multivariable logistic regression analysis was performed to clarify the associations between falling and the use of these psychotropics. RESULTS: Univariable analyses demonstrated that the use of every class of psychotropic was statistically significantly associated with falling. Moreover, the association of the use of hypnotics with falls remained significant in the multivariable logistic regression model built including potential confounding factors, such as age, sex, inpatient department, body mass index, fall risk score measured by a fall risk assessment sheet completed on hospital admission, and the use of other classes of psychotropics. CONCLUSIONS: Our findings suggest that the use of hypnotics may be a risk factor for falling in hospitalized patients.

AIM: To describe the development and acceptability of a decision aid (DA) for chronic insomnia considering discontinuation of benzodiazepine (BZD) and benzodiazepine receptor agonist (BZRA) hypnotics, and if discontinuing, tapering with or without cognitive behavioral therapy for insomnia (CBT-I). METHODS: We reviewed relevant literature describing chronic insomnia to identify options. We used the results of the systematic review and meta-analysis conducted previously to determine the related outcomes of two options: discontinuation of BZD/BZRA hypnotics by gradual tapering alone and discontinuation of BZD/BZRA hypnotics by gradual tapering with CBT-I. We then developed a prototype of DA following the International Patient Decision Aid Standards. A mixed methods survey was conducted to assess the acceptability among patients and healthcare providers. RESULTS: The prototype consisted of a description of insomnia, options of continuing or discontinuing BZD/BRZA hypnotics (if discontinuing, the options of tapering hypnotics with or without CBT-I), pros and cons of each option, and a value clarification exercise. Patients (n = 24) reported that the DA had acceptable language (79%), adequate information (71%), and well-balanced presentation (91%). Healthcare providers (n = 20) also provided favorable feedback. CONCLUSION: We developed a DA for chronic insomnia considering discontinuation of BZD/BRZA hypnotics, which was acceptable for stakeholders. The developed DA was designed to support patients and healthcare providers to make a decision about whether to discontinue BZD/BRZA hypnotics.

Introduction: Although physical activity and exercise are generally thought to have favorable effects on mental health, excessive physical activity may have unfavorable effects. In this study, the associations between physical activity and the states of mental health with U-shaped dose-response curves were hypothesized, and the ranges of physical activity resulting in optimal effects on mental health were investigated. Methods: A cross-sectional survey was conducted on 1,237 adult volunteers in 2017 and 2018. Of these volunteers, 526 participants validly answered the self-administered questionnaires asking about physical activity, depression, anxiety, resilience, insomnia vulnerability, and life events. A comparison of mental health measures by physical activity levels and quadratic equation model regressions were performed. Results: No significant linear associations between physical activity levels and mental health measurements were observed; however, the U-shaped, quadratic equation models indicated a significance. The following levels of physical activity per week optimized the mental health measurements values of the participants: 6,953 MET-minutes and 25.70 h for depression, 5,277 MET-minutes and 21.60 h for state anxiety, 5,678 MET-minutes and 22.58 h for trait anxiety, 25.41 h for resilience, and 9,152 MET-minutes and 31.17 h for insomnia vulnerability. Conclusion: Physical activities in the optimal range were associated with more favorable mental health measurements. Physical activities that were too much or too long and outside of the optimal range were associated with less favorable mental health measurements.
