RESUMO
BACKGROUND: In this study, we developed and tested the validity and reliability of the 12-item Rest and Recreation Quality Scale (RRQ-Scale) for Workers as a new scale capable of conveniently assessing the quality of workers' days off, that is, their rest and recreation. METHODS: Participants included 756 employees (694 men, 62 women, mean age ± SD= 44.7 ± 13.5, age range = 18-81) of 26 manufacturing-related companies located in Oita Prefecture, Japan. We analyzed the factorial validity of the scale's score distribution and its criterion-related validity and reliability (Cronbach's coefficient α), compared to MOS 36-Item Short-Form Health Survey version 2.0 (SF-36v2) and the generalized self-efficacy scale. Participants responded to the 12 questions on 4-point scales; these were summed to calculate the total score (score range: 12-48 points). RESULTS: The smallest and largest mean ± SD of the questions were 2.53 ± 0.89 and 3.21 ± 0.74, respectively, which are within the possible score range (1-4, implying the absence of floor and ceiling effects). A confirmatory factor analysis indicated that the goodness of fit of the higher-order factor analysis model was satisfactory (GFI = 0.955), confirming factorial validity. In addition, consistent with the theoretical predictions, the total score exhibited statistically significant positive correlations with the components of the SF-36v2; physical component summary (PCS): rs = 0.193, P < 0.001, mental component summary (MCS): rs = 0.369, P < 0.001, and role/social Component Summary (RCS): rs = 0.115, P = 0.002. This confirmed criterion-related validity. Further, the overall reliability of the scale was high; α = 0.877. CONCLUSION: In sum, the score distribution, validity, and reliability of the RRQ-Scale for workers were good, indicating a high degree of practicality.
RESUMO
OBJECTIVES: We are responsible for answering the research question, "Does a return-to-work program improve the returning outcome?" This is one of the six research questions in the evidence-based "Return-to-work Guidance in Occupational Health 2017" developed by the Kanto branch of the Japanese Society of Occupational Health. This study aimed to integrate the effectiveness of the return-to-work program to improve the state of sick-listed employees suffering from cardiovascular disease, cancer, and musculoskeletal and mental health problems. METHODS: Three different databases, PubMed, Cochrane Library, and Ichushi-Web were searched. Based on the results of a systematic review, the guidance developing group created the draft of the recommendations with evidence to decision framework and used a poll to determine the recommendations. We integrated the evidence from a systematic review and meta-analysis at the disease level. This study protocol was registered with PROSPERO (the registration number is: CRD42016048937). RESULTS: A total of five articles on musculoskeletal diseases and six on mental health problems were retrieved. No articles in the cardiovascular and cancer areas matched the eligibility criteria. When workers suffered from musculoskeletal disorders, the rehabilitation group statistically returned to work earlier than the usual care group did [HR 1.58 (95% CI 1.26-1.97), -40.71days (95% CI -60.69--20.72) ]. In the mental health problems group, the psychological intervention program group had statistically less days of sick leaves as compared to that in the usual care group [-18.64 days (95% CI -27.98--9.30) ]. CONCLUSIONS: It might be suggested that work environment management, work management, tackling psychological problems, cognitive behavioral approach, and several meetings with supervisors and occupational health staff, in addition to a direct focus on backache contributed to the early return-to-work of workers suffering from musculoskeletal disease. Regarding mental health problems, interviews with a psychological approach and consultations with psychologists and psychiatrists might be effective in reducing the days of sick leaves. However, because these methods were investigated in Europe, we need to be careful when introducing these practises in Japan due to the differences in the occupational health support systems. Further, high quality evidence level studies are needed in Japan.

BACKGROUND: A limited number of longitudinal studies have addressed the association between sleep disturbance and mental health status among adolescents. To examine whether each of these is a risk factor for the onset of the other, we conducted a prospective longitudinal study of Japanese adolescents. METHODS: In 2004, we performed a baseline study of students attending three private junior high schools in Tokyo, and in 2006, a follow-up study was performed on the same population. The mean age of the subjects was 13 years. The Pittsburgh Sleep Quality Index was used to evaluate sleep disturbance, and the 12-item General Health Questionnaire was used to evaluate mental health status. RESULTS: The subjects were 698 students, of whom 516 were suitable for analysis. The incidence of newly developed poor mental health status during the 2 years leading to the follow-up study was 35.1%. New onset of poor mental health status was significantly associated with new onset of sleep disturbance and lasting sleep disturbance. The incidence of sleep disturbance during the 2 years leading to the follow-up study was 33.3%. New onset of sleep disturbance was significantly associated with new onset of poor mental health status and lasting poor mental health status. CONCLUSIONS: Sleep disturbance and poor mental health status increase each other's onset risk.

OBJECTIVE: This study was conducted to clarify the prevalence of alcohol consumption among pregnant women in Japan and its associated factors. METHOD: 344 institutions participated in the survey which was conducted in February 2006. Each subject was requested to fill out a self-administered anonymous questionnaire. Factors associated with alcohol consumption during pregnancy were examined using the chi-squared test and logistic regression analysis. RESULTS: The number of effective responses was 18,965. The prevalence of alcohol consumption before the confirmation of pregnancy and during pregnancy was 44.6% and 4.6% respectively. The following items were recognized as being associated with promoting alcohol consumption during pregnancy: greater number of weeks of pregnancy, more pregnancies, fewer years of schooling, being employed, an alcohol consumption before the confirmation of pregnancy, smoking during pregnancy, ignorance about the effects of alcohol consumption on fetuses, receiving advice regarding alcohol abstention, difficulty maintaining sleep, and daytime sleepiness. CONCLUSION: It is important to have a more comprehensive understanding of the factors associated with the alcohol consumption behavior of pregnant women, as revealed in the present study, in order to develop future policies for preventing alcohol consumption among pregnant women.

BACKGROUND: Pregnancy and childbirth can act as strong factors motivating parents to spontaneously quit smoking. The aim of the present survey was to establish smoking cessation guidelines for this group. The objectives were to clarify the smoking status of parents before, during and after pregnancy, as well as the factors associated with continuous smoking during pregnancy and post-partum smoking relapse among women who had stopped smoking during pregnancy. METHODS: A cross-sectional survey with self-administered questionnaires was conducted for the parents of the 908 infants who participated in the official medical and dental examination for 18-month-old infants in Itabashi ward, Tokyo, Japan. RESULTS: The prevalence of smoking among women before, during pregnancy, and at post-partum 18 months at 95% confidence intervals was 29.3% (23.3-35.3%), 9.8% (3.0-16.6%), and 23.1 (16.8%-29.4%), and among their spouses it was 64.3% (60.0-68.6%), 58.1% (53.4-62.7%), and 58.2% (53.5-62.8%), respectively. The positive factors associated with smoking among pregnant women were marriage to a smoker, less education, under stress, and part-time employment rather than unemployment. The positive factors associated with smoking relapse after childbirth among women were breast-feeding <6 months and age under 30 years. CONCLUSION: Compared with Western countries, the rate of smoking cessation during pregnancy was relatively high in Japan. It is necessary that smoking cessation intervention and support for men be initiated at the early stages of their spouses' pregnancies. These observations could influence the targeting and design of maternal smoking intervention.

OBJECTIVE: The purpose of this study was to examine the association between sleep and subjective quality of life in an elderly Japanese population. METHODS: Elderly people aged 70 years or more (n=1,769) were selected randomly from all areas of Japan. They were visited and interviewed in November 2003. Subjective well-being of the subjects was assessed using the Philadelphia Geriatric Center (PGC) Morale Scale. A logistic regression analysis was performed using sleep-related factors as explanatory variables. RESULTS: A positive linear association was observed between subjective sleep sufficiency and the mean PGC Morale Scale score. The crude and adjusted odds ratios for sleep disorders such as difficulty initiating sleep, excessive daytime sleepiness, and restless legs syndrome were significantly low. The mean score was highest for a sleep duration of 7-8h and became lower at sleep durations of <6 and 9h (inverted U-shaped association). However, the adjusted odds ratio for sleep duration did not show a significant reduction. CONCLUSIONS: In order to improve the subjective well-being of the elderly, better subjective sleep sufficiency and alleviation of sleep disorders are necessary. Different mechanisms may reduce subjective well-being in individuals who sleep less than 6h or who sleep 9h or more.

OBJECTIVE: The association between sleep habits and hemoglobin A1c (HbA1c) level has not been sufficiently examined. In the present study of residents in a local community, the associations between sleep duration and HbA1c level were examined. METHODS: Self-administered questionnaires were mailed to 1062 residents in a rural community in Japan, and completed questionnaires were collected. At the time of collection, the fasting plasma glucose and Hb(1c levels were measured using peripheral blood samples. For the analyses, values that were considered to represent high levels were a fasting plasma glucose level of 126mg/dl and a HbA1c level of 6.5%. Logistic regression analyses were performed to examine the associations between sleep duration and high fasting plasma glucose or high HbA1c levels. RESULTS: The prevalence of high fasting plasma glucose and high HbA1c levels was significantly high (p<0.01) in subjects with a short or a long sleep duration. Logistic regression analyses demonstrated a significant association between high HbA1c level and sleep duration. The adjusted odds ratios for a high HbA1c level showed high values with regard to both short and long sleep durations. CONCLUSIONS: HbA1c level showed a U-shaped association with sleep duration. These results suggest that there may be an appropriate range of sleep duration in individuals with glucose tolerance disorders. It is expected that the present findings will contribute to the treatment and prevention of diabetes mellitus.

STUDY OBJECTIVE: Pregnant women suffer from sleep disturbance, which may be aggravated by passive smoking. In this study we investigated the effects of passive smoking on sleep disturbance during pregnancy. DESIGN: Two cross-sectional questionnaire surveys conducted in 2002 and 2006. SETTING: Clinical institutions specializing in obstetrics and gynecology that participated in the nationwide surveys: 260 in the 2002 survey and 344 in the 2006 survey. PARTICIPANTS: 16,396 and 19,386 pregnant women in Japan surveyed in 2002 and 2006, respectively. INTERVENTION: N/A. MEASUREMENTS AND RESULTS: Pregnant women exposed to passive smoking were likely to have sleep disturbances, such as subjective insufficient sleep, difficulty in initiating sleep, short sleep duration, and snoring loudly/breathing uncomfortably. Smoking pregnant women had the same sleep disturbances and also experienced excessive daytime sleepiness and early morning awakening. The prevalence of 5 types of sleep disturbance (insufficient sleep, difficulty in initiating sleep, short sleep duration, excessive daytime sleepiness, and snoring loudly/breathing uncomfortably) among nonsmokers with environmental tobacco smoke showed a mean value intermediate between that of active smokers and that of nonsmokers without environmental tobacco smoke. CONCLUSION: Passive smoking is independently associated with increased sleep disturbance during pregnancy.

OBJECTIVE: The present study was conducted to clarify the prevalence of the use of alcohol and hypnotic medication as sleep aids, and associated factors, in the general population in Japan. METHODS: The survey was conducted in June 2000, using self-administered questionnaires, targeting a population that was selected randomly from among 300 communities throughout Japan. A total of 18,205 responses indicating alcohol use and 16,804 responses indicating hypnotic medication use were analyzed. RESULTS: The prevalence of alcohol use as a sleep aid one or more times per week was 48.3% among men and 18.3% among women. The prevalence of the use of hypnotic medication one or more times per week was 4.3% among men and 5.9% among women. The prevalence of alcohol used as a sleep aid increased gradually for men and women up to age 55-59 years and 40-44 years, respectively, and then declined with increasing age thereafter. The prevalence of the use of hypnotic medication among both men and women showed a trend toward a gradual increase with age. The use of alcohol as a sleep aid was associated with "difficulty maintaining sleep," but no such problem was associated with the use of hypnotic medication. CONCLUSIONS: Alcohol is a more popular sleep aid than hypnotic medication. The factors associated with the use of alcohol and of hypnotic medication are different.

OBJECTIVE: This study was conducted to estimate the prevalence of smoking among pregnant women living in Japan and to analyze the factors associated with their smoking behavior. METHOD: Five hundred institutions with maternity services were randomly sampled from a list of the Japan Association of Obstetricians and Gynecologists. Of these institutions, 260 participated in the survey which was conducted in February 2002. Using a self-reported anonymous questionnaire, a survey on smoking behavior, drinking behavior and sleep status was conducted on pregnant women. Chi-square tests and logistic regression analyses were used to examine the factors associated with their smoking behavior. RESULTS: Data were obtained from a total of 16,414 pregnant women. The prevalence of smoking during pregnancy was 9.9% [95% confidence interval (CI) 9.4%, 10.4%]. The quit rate of smoking among pregnant woman was 61.9% [95% CI 60.4%, 63.4%]. The odds ratios for smoking during pregnancy were significantly higher in women with relatively young age, less schooling, multiparous, exposure to passive smoking, short sleep duration and in women who drank. CONCLUSION: Smoking among pregnant women remains an important public health problem in Japan. It is necessary to promote antismoking measures based on the results of this study.

OBJECTIVE: Among the existing epidemiologic studies that have examined the relationship between depression and sleep disturbances, there are few nationwide studies that have been conducted on subjects representing the general population. The present study was therefore conducted to clarify the relationship between depression and sleep disturbances, in particular the relationship between depression and both sleep duration and subjective sleep sufficiency, using a large sample representative of the general population. METHOD: The survey was conducted in June 2000, using self-administered questionnaires, targeting a population that was selected randomly from among 300 communities throughout Japan. Among the respondents, data from 24,686 individuals aged 20 years or older were analyzed. The Center for Epidemiologic Studies Depression Scale was used to assess the presence of depression. Sleep status, including sleep duration, subjective sleep sufficiency, and the presence or absence of insomnia symptoms, was evaluated. RESULTS: Those whose sleep duration was less than 6 hours and those whose sleep duration was 8 hours or more tended to be more depressed than those whose sleep duration was between 6 and 8 hours. Thus, sleep duration exhibited a U-shaped association with symptoms of depression. As subjective sleep sufficiency decreased, symptoms of depression increased, indicating a linear inverse-proportional relationship. CONCLUSION: The fact that sleep duration and subjective sleep sufficiency exhibited different relationships with symptoms of depression indicates that these 2 sleep parameters each have their own significance with regard to depression. These findings may be useful in the medical management of mental diseases.

BACKGROUND: Benefits of breast-feeding are not only limited to nutrition and sanitation in developing countries but also extend to cost-saving health care and alleviation of anxiety related to childrearing in developed countries. This study aims to elucidate factors associated with exclusive breast-feeding in Japan and use this information to achieve child-rearing support worldwide by promoting breast-feeding. METHODS: This cross-sectional study used data from a survey conducted by Ministry of Health, Labour and Welfare of the Japanese government, the First Longitudinal Survey of Babies in 21st Century. All subjects were infants (n=53,575) born in Japan in 2001 between January 10 and 17 and between July 10 and 17. According to the data, the exclusive breast-feeding rate in Japan during the first 6 months of life was 21.0%. We examined the factors associated with exclusive breast-feeding using univariate and multivariate logistic regression analyses. RESULTS: Among the factors examined, the adjusted odds ratio (OR) for exclusive breast-feeding was low for late childbearing, low birth weight infants, multiple births, smoking parents, living with grandparents, and feeling burdened by childrearing. The adjusted OR was high for factors that included sufficient childcare leave and consultation about childrearing with the spouse, a birth attendant and/or nurse, and a peer in a child-rearing circle. CONCLUSIONS: Exclusive breast-feeding is associated not only with medical factors but also with social factors. This study clarifies the necessity of social support to reduce the child rearing burden and a political system to promote paternal participation in childrearing and to improve the childcare leave system.

BACKGROUND: Passive smoking is a well-known health hazard for infants. This study was conducted to: (1) estimate the prevalence of passive smoking among Japanese infants and (2) clarify the prevalence of indoor smoking and associating factors among parents having infants. METHODS: Subjects were all 53,575 infants born throughout Japan on January 10-17, 2001 or July 10-17, 2001. When the infants reached 6 months of age, the questionnaires were mailed to the homes. Family members answered questions that included information about the current smoking behavior of the parents. RESULTS: A total of 44,562 questionnaires (83.2%) were analyzed. The prevalence of smoking among the mothers and the fathers were 17.1% and 63.5%. The percentages of mothers and fathers who smoked indoors were 12.1% and 36.2%. The percentage of households where mothers and/or fathers smoked indoors was 37.5%. Multivariate logistic analysis indicated that young age, having a spouse who was a smoker, infants having many siblings, the mother not breast-feeding, and lower annual incomes had significantly higher odds ratios for both the mother's and the father's indoor smoking. CONCLUSIONS: Passive smoking is common among Japanese infants. To protect Japanese infants from passive smoking, further public health measures must be taken.

BACKGROUND: Excessive daytime sleepiness is one of the principal symptoms of sleep disturbances, and is often associated with serious consequences including traffic and industrial accidents, decreased productivity, and interpersonal problems. However, there are few epidemiologic studies on excessive daytime sleepiness in a large scale sample targeting Japanese general population. METHODS: The survey was performed using a self-administered questionnaire in June 2000, targeting a population randomly selected from among 300 communities throughout Japan. This questionnaire included information about sleep habits and sleep problems. Excessive daytime sleepiness measured according to a question "Do you fall asleep when you must not sleep (for example when you are driving a car)?" RESULTS: A total of 28,714 subjects completed the questionnaire. The prevalence of excessive daytime sleepiness was 2.5% (male=2.8% and female=2.2%). Backward elimination analysis showed that the following were associated with excessive daytime sleepiness: male sex, young age, short sleep duration, subjective insufficient sleep, loss of deep sleep, disagreeable sensations in the legs, interruption of sleep by snoring or dyspnea, and feeling psychological stress. Interruption of sleep by snoring or dyspnea was the strongest associated factor (adjusted odds ratio=2.46, 95% confidence interval=1.76-3.43) of excessive daytime sleepiness. CONCLUSIONS: These results suggest that excessive daytime sleepiness in Japanese is associated with several sleep problems. These findings may be useful in attempts to prevent excessive daytime sleepiness in the general population of Japan.

A questionnaire survey was conducted with questions from the 12-item General Health Questionnaire, among others, targeting 4,407 nurses in 8 general hospitals in Japan, in the hope of improving the work environment of nurses and to provide data that will allow a discussion of the measures necessary for preventing medical errors, thus improving occupational health. For each type of accident, the percentage of those who had made medical errors was significantly higher for the "mentally in poor health" group than for the "mentally in good health" group (p<0.0001). The percentage of nurses in the "mentally in good health" and "mentally in poor health" groups who had experienced occupational accidents over the past 12 months (i.e., whether they were "with errors" or "without errors") was calculated for each of the following four types of medical accident: (1) drug-administration errors, (2) incorrect operation of medical equipment, (3) errors in patient identification, and (4) needlestick injuries. For each type of accident, the percentage of those who had made medical errors was significantly higher for the "mentally in poor health" group than for the "mentally in good health" group (p<0.0001). Multiple logistic regression analyses revealed significant associations between experience of medical errors in the past 12 months and being mentally in poor health, with night or irregular shift work, and age.

PURPOSE: The actual situation regarding the lifestyle of college students in Japan cannot be said to be healthy and future reduction of bone mass is a possible matter for concern. However, there have been only a few reports about the relationship between lifestyle during this period and bone mass, and especially none focusing on males not affected by female hormones. The purpose of this study was thus to investigate the relationship between bone mass and lifestyle in college students of both sexes. METHODS: Seven hundred and sixty-six college students of both genders were enrolled in this study as subjects and underwent calcaneal quantitative ultrasound with an AOS-100 device (ALOKA). At the same time physical factors, lifestyle and nutrition were also examined with laboratory findings. RESULTS: Physical factors such as stature, weight, body mass index (BMI), percentage body fat and gripping power were more strongly related to calcaneal quantitative ultrasound among females than in male students. Multiple regression analysis using calcaneal Osteo Sono-Assessment Index (OSI) as the dependent variable, and physical factors, lifestyle and nutrition, and laboratory findings as the independent variables, indicated that regular physical activity was strongly related to OSI in both sexes. The OSI in the alcohol-consuming group was significantly higher than that in the non alcohol-consuming group in males, and demonstrated a significant negative correlation with liver function markers, i.e. ALT (GPT) IU/l. CONCLUSION: It is very necessary to undertake daily physical activity for primary prevention of osteoporosis in both males and females. Bone mass in the alcohol-consuming group was here found to be significantly higher than that in the non alcohol-consuming group, but the study suggested that if the amount of alcohol consumed reaches an extent where liver function markers are affected, bone mass may decrease.

STUDY OBJECTIVES: To clarify the prevalence of restless legs syndrome (RLS) in pregnant women living in Japan and to analyze the relationship between sleep problems and RLS, in order to discuss ways for pregnant women to obtain comfortable sleep and to improve the health of both the mother and child. DESIGN: A cross-sectional questionnaire survey. SETTING: 500 clinical institutions with maternity services were randomly sampled from a list of organizations identified in a survey by the Japan Association of Obstetricians and Gynecologists. Of these 500 institutions, 260 participated in the survey. PARTICIPANTS: 16,528 pregnant women living in Japan. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: In this survey of pregnant women, the prevalence of RLS was found to be 19.9%. An analysis was conducted on the relationship between RLS and other factors such as subjective evaluation of sleep, difficulty initiating sleep, difficulty maintaining sleep, early morning awaking, and excessive daytime sleepiness. The result of this analysis suggested that women with these sleep-related problems were more likely to have RLS than those without. In addition, RLS was more prevalent in the later stages of pregnancy. CONCLUSION: In the pregnant women in our survey, the prevalence of RLS was found to be 19.9%, which is higher than the prevalence of RLS that has been found in the general public in a previous study. This suggests that RLS-related sleep problems may be an important public health issue among pregnant women in Japan. This finding may have implications for attempts to improve sleep hygiene in this group.

OBJECTIVE: The objective of the study was to identify: 1) what kinds of sleep problems that pregnant women experience in Japan; and 2) the relationships between sleep problems and month of pregnancy, sleep problems and the number of pregnancies, and sleeping hours, by means of a questionnaire given to pregnant women in Japan. Conditions to assure good quality sleep were studied. METHODS: Of 500 obstetric facilities which were randomly selected from areas surveyed by the Japan Association of Obstetricians and Gynecologists, 260 finally agreed to participate in this study. Women who had their pregnancy confirmed and were on a revisit to the 260 obstetric facilities were enrolled. These pregnant women completed anonymous self-administered questionnaires during the waiting time for treatment and submitted them to the obstetric facilities in sealed envelopes. The questionnaire covered personal attributes such as age and highest level of education, pregnancy status, working status, and patterns of smoking and alcohol drinking. Sleep-related items such as 1) subjective sleep quality, 2) difficulty in getting to sleep, 3) frequent awakenings, 4) waking up too early, 5) sleeping hours and 6) daytime drowsiness were also included. RESULTS: The month of pregnancy was significantly related to four sleep-related items, including difficulty in getting to sleep and waking up too early. With respect to the relationship between the number of pregnancies and sleep problems, significance was found for five sleep-related items, including subjective sleep quality and waking up too early. Poor subjective sleep quality was significantly related to sleeping less than seven hours and whether or not pregnant women had a regular job. It was also suggested that the greater the number of pregnancies, the shorter the sleeping hours. When responses to each sleep-related item were compared between pregnant women and the general population, the former were more likely to have sleep problems. CONCLUSION: These findings suggest that as well as the number of pregnancies and month of pregnancy with sleeping hours may be factor intimately related to sleep problems during pregnancy. A good quality sleep during pregnancy is vital for normal maternal health and fetal growth and sufficient sleeping hours are therefore needed. Attention should therefore be paid to the finding that pregnant women were more likely to have sleep problems than the general population.
