Addressing Japan's fertility decline: influences of unintended pregnancy on child rearing.

Japan has been experiencing a continuing decline in fertility and an increase in premarital conceptions and abortions among young people. Child rearing is often viewed as a burden. In response, Japan is now seeking ways to improve the child-rearing environment for parents. In this context, we conducted a prospective study among 206 pregnant women in Sukagawa City, Fukushima, to explore the influences of pregnancy intention on child rearing. We found that unintended pregnancy was associated with a higher risk of negative child-rearing outcomes, including lower mother-to-child attachment, increased negative feelings of mothers and a lower level of participation of fathers in child rearing. Unintended pregnancy exacerbates the real and perceived burdens of child rearing. Japan is currently facing a conflict between wanting to reduce unintended pregnancies and increase the national fertility rate. We believe the government needs to address the social challenges affecting people's family lives, which underpin low fertility, rather than focus on fertility decline per se. We suggest Japan seeks to reduce unintended pregnancies and provide support to parents at high risk of child-rearing difficulties. We also suggest adopting a comprehensive approach to improving the lives of young couples, with a focus on adolescents, including life-skills education to prepare for adulthood, marriage and parenthood.

[Production of a fall prevention exercise programme considering suggestions from community-dwelling elderly].

OBJECTIVES: A fall prevention exercise programme, which elderly persons could undertake in their home alone to maintain and improve leg muscle strength, body balance ability and flexibility, was developed. The programme consisted of number of movements from which the best were selected on the basis of participant evaluation. The purpose of this report is to document the actual contents and an examination of the effects of this exercise programme in elderly people. METHODS: A total of 551 elderly persons, aged 75 years and over, not needing the support of elderly care insurance in S town, Miyagi Japan, were the subjects of this study. An intervention area and a non-intervention area were set in the study region. In the intervention area, 85 elderly people of high-risk for falls were selected to perform a longitudinal intervention study for one year. The selection criteria were as follows: 1) Maximum walking speed slower than median value, 2) Falls had been experienced in the past year. Forty elderly persons (15 men and 25 women) participated in the class. Thirty movements designed to improve flexibility, leg muscle strength, and body balance, and to prevent tripping were executed and evaluated. Effects of this intervention on participants in the fall prevention class were examined using a follow-up survey one year after the baseline survey. The outcome of the fall prevention exercise programme was measured in terms of incidence of falls. RESULTS: A final fall prevention exercise programme consisting of ten movements was produced by the intervention. In addition, seven movements using a chair were part of the exercise programme. METS of the exercise programme for students, leaders, and elderly persons were 3.41 +/- 0.37, 3.16 +/- 0.47, and 3.08 +/- 0.4, respectively. The incidence of falls over one year of the participants in the class significantly decreased from 48.4% at baseline survey to 25.8% at follow-up survey, but that of non-participants did not change. One-leg standing times with eyes open of the female participants significantly extended from the baseline survey to the follow-up survey, but not that of non-participants. CONCLUSIONS: This result of intervention suggested that incidence of falls was decreased by the execution of the exercise programme in twelve sessions of fall prevention class and at home.

[An evaluation of teaching objectives for seminars and clerkship of social medicine in medical schools in Japan].

OBJECTIVES: The purpose of this study was to evaluate the curriculum of seminars and clerkship for social medicine in medical schools in Japan, with special reference to teaching objectives. METHODS: A survey was conducted in December, 2002 by sending questionnaires to all the member departments of the Conference for Hygiene and Public Health Teaching in Medical Schools in Japan. Teaching objectives for seminars and clerkship of social medicine stated in their curricula were analyzed by frequencies of key words related to learner's "Knowledge, Attitude, and Behavior". Also, five professors of public health independently rated the stated teaching objectives using nine evaluation criteria divided into three levels and mean ratings were obtained. RESULTS: Although 80% of the schools described their General Instructional Objectives (GIOs), only 63% of the universities stated Specific Behavioral Objectives (SBOs). Evaluation of the contents of the descriptions revealed that, although many courses described the GIOs with the student as subjective, only a small number of courses mentioned "Attitude and Behavior" in SBO. Also, many courses did not make any apparent distinction between GIOs and SBOs. CONCLUSIONS: Practical training is a crucial component in medical education and seminars and clerkship play an important role in teaching social medicine to medical students. However, the present study revealed that many medical schools in Japan do not have adequately defined teaching objectives. Improvement of the curricula in courses of social medicine is required with particular reference to specific behavioral objectives and goals for seminars and clerkship.

[Health practice and total mortality among middle-aged and elderly residents in Sukagawa, Japan].

PURPOSE: The present study aimed to clarify the relationship of total mortality with the HPI (health practices index: the additive index of five health practices) and lifestyle among elderly residents in a Japanese cohort. METHODS: A population-based prospective study was conducted in Sukagawa City of Fukushima Prefecture, Japan. Self-administered questionnaires were distributed and collected via mail. One-third of the city residents aged 40-69 years and over 70 years were randomly selected. Baseline surveys were conducted in February 2001 for the '40-69 cohort' and in July for the 'over 70 cohort'. Among 8746 subjects in the '40-69 cohort' and 2718 in the 'over 70 cohort', 5,657 (64.7%) and 2,019 (74.3%) responded, respectively. The questionnaires consisted of items on 'Alameda seven health practices' (weight, sleeping, smoking, drinking, breakfast, exercise, snacking), medical history, perceived health status, and home bound status of the 'over 70 aged cohort'. We followed the younger cohort for 3 years and 7 months and the elderly cohort for 3 years and 3 months until the end of October 2004, and checked their survival status using a municipal resident registry. Analysis of factors associated with total mortality one year after the baseline survey employed a simple chi2 test, Kaplan-Meier survival analysis, and the Cox proportional-hazards model to compute relative risks (RRs). The HPI was the additive index of five health practices: weight, sleeping, smoking, drinking, exercise. RESULTS: 1. No significant association was observed between lifestyle and total mortality in the '40-69 cohort'. However, there were significant links between total mortality in the 'over 70 cohort' and HPI and exercise. 2. The Kaplan-Meier curves for the 'over 70 cohort' showed higher survival for the group with higher HPI scores. Again, results of the Cox proportional-hazards model showed no factor significantly associated with the total mortality of the '40-69 cohort'. For the 'over 70 cohort', HPI, age, sex, subjective health and housebound status were associated. Medical history did not show any significant influence. For each of 'the Alameda 7 health practices', exercise was associated with all-cause mortality. CONCLUSION: 1. Maintaining good health practices improves life prognosis of the elderly. 2. The HPI is an useful indicator of life prognosis. 3. Promotion of exercise and prevention of becoming housebound are important for improving life prognosis.

Prevalence of and factors associated with reproductive tract infections among pregnant women in ten communes in Nghe An Province, Vietnam.

BACKGROUND: A community-based survey was conducted to investigate reproductive tract infections (RTIs) among pregnant women in Vietnam, where epidemiologic data on these infections are scarce. METHODS: The focus of the study were: candidiasis, bacterial vaginosis, group B streptococcal infection,trichomoniasis, gonorrhea, syphilis, and hepatitis B. In addition to their prevalence, a generalized estimating equation was used to analyze infection-associated factors and diagnostic test analysis to examine the accuracy of currently performed presumptive clinical diagnoses. RESULTS: Among 505 pregnant women in 10 communes, 182 (36%) had at least one infection with a wide regional variation in prevalence. The most prevalent infection was candidiasis (17%); sexually transmitted infections were rare except hepatitis B (10%); and the prevalence of bacterial vaginosis and group B streptococcal infections was 7% and 4%, respectively. Two factors were associated with the decreased risk of endogenous infections: a higher household assets score (odds ratio [OR] = 0.67) and condom use (OR = 0.15). Not living with a husband (OR = 1.55) was associated with an increased risk. For hepatitis B, three factors were associated with a decreased risk: employment by the government (OR = 0.26), higher education (OR = 0.18), and being older at the time of first sexual intercourse (OR = 0.58). Women's self-reported symptoms and clinical findings had low positive predictive values. Only clinical findings from the vaginal wall showed both a sensitivity and specificity over 50%. CONCLUSIONS: Suggested recommendations are: extensive application of microscopic diagnosis, prevention of hepatitis B transmission, and addressing the issues of regional differences in the prevalence of RTI and of less wealthy people.

Association of pregnancy intention with parenting difficulty in Fukushima, Japan.

BACKGROUND: Our prior study revealed that nearly half of the Japanese women between the ages of 35 and 49 years experience an unintended pregnancy, many of which are carried to term. The present study is intended to investigate the association of the intention to become pregnant with parenting difficulty after birth. METHODS: We distributed self-administered questionnaires to mothers of 317 randomly selected children aged 3 to 18 months who resided in Sukagawa City, Fukushima. The extent to which the unintended pregnancy is associated with the risk of negative attitude in parenting was examined by using multiple logistic regression analysis. RESULTS: The response rate was 69% and the proportion of births, the outcome of an unintended pregnancy, 22%. When the pregnancy was unintended, the mother may not deny her feelings toward child abuse (odds ratio [OR] = 5.2). She was unlikely to have discussion about child rearing with her husband (OR=3.1) or family (OR=3.3); or the husband rarely participate in child rearing (OR=1.9). CONCLUSION: To improve the child rearing environment, these findings provide preliminary evidence to underscore the importance of pregnancy planning and providing services to augment the parenting skills of couples who have an unintended pregnancy. A follow-up of pregnant women is currently underway to examine prospectively the effects on child rearing of one's intention to become pregnant.

[Survey on public health nursing education-in the comparison of nursing education courses, universities, advanced courses for public health nurse with junior nursing colleges, and public health nursing school].

PURPOSE: Changes in public health nursing education have been consideration. Theses changes include a dramatic increase in the number of public health nurses (PHNs) who have enrolled for nursing courses at university. This study was conducted to assess the current status and future of public health nursing education as perceived by teachers and students at three types of schools: universities offering nursing courses, advanced courses for PHNs with junior nursing colleges, and public health nursing schools. METHODS: Questionnaires were distributed to teachers and students by mail. The questions that were sent to teachers asked which subjects were required to become a certified PHN, which lecture methods were employed to teach public health-particularly community health assessment methods, and what was the level of awareness of the activities of PHNs. Students were asked about their motivation to be a PHN, their understanding of public health, their views of public health activities and their images of PHNs. RESULTS: Responses were analyzed and differences between questionnaires from different schools were noted. These included the number of subjects and the total number of hours spent doing practical training and field experience in universities and the other types of schools, and the number of teachers. Differences also were noted among students at three types of schools about their age, methods of public health activities, knowledge about activities undertaken by PHNs, and their images of PHNs. No differences were observed among the schools with respect to the students' conceptual understanding of public health. CONCLUSION: Student age, practical training and field experience were found to contribute to their level of understanding of public health and public health nursing. It is thus necessary to consider the teaching methods employed by universities that administer nursing courses and the effectiveness of courses offered by graduate schools.

[Effect of a life review process to improve quality of life for the homebound elderly in Japan].

OBJECTIVE: This study examined the therapeutic effects of Life Review processes on physical and psychological functions of homebound elderly in Japan. METHODS: From 1998, a cohort of people aged 65 and over living in two cities in Yamagata Prefecture has been followed. Sixty-three subjects (24 men, 39 women) were classified as rank A (homebound). Fifty-two persons completed the baseline survey in 1999 and 46 eligible persons (18 men and 28 women) were allocated to intervention and control groups whose age and sex distribution were matched. Intervention entailed giving some health information and Life Review processing for four months, twice a month on average. Each session started with provision of health information followed by the Life Review process which took an hour to finish. All subjects of both groups were assessed for dependent variables at the beginning and the end of the intervention period (pretest and post-test). Dependent variables were physical (Activities of Daily Living, Visual deficit, and others), psychological (subjective health, life satisfaction, self-efficacy scale, and others), and social (functional ability and frequency of getting out of the house). The control group received only the pretest and the post-test. RESULTS: Pretest scores for all physical, psychological, and social variables did not significantly differ between the two groups. The rate for improvement/no change were higher with regard to hearing deficit, ADL (eating, dressing), cognition, subjective health, ikigai and frequency of getting out of house in the intervention group than in the control group, but there were no significant differences. CONCLUSION: The developed intervention program featuring delivery of health information and structured Life Review Process had no negative influence on physical and psycho-social functions. Practicability of the intervention was suggested. But the study highlights problems such as selection of subjects, duration and method of intervention.

Association of health behavior and social role with total mortality among Japanese elders in Okinawa, Japan.

BACKGROUND AND AIMS: Longitudinal studies on the relationship of life-style factors and social networking with mortality have been only slightly conducted in a comprehensive manner among the Japanese elderly. This study aims at examining associations of health behavior and social role with total mortality among Japanese elders in Okinawa. METHODS: All residents aged 65 years or older were recruited in 1987 from the village of Ohgimi, and 724 subjects were followed for 12 years. A comprehensive health assessment questionnaire was used, and the resulting data were analyzed by the Cox proportional hazards model. RESULTS: The number of deaths during the study period was 139 (55.4%) for men and 166 (35.1%) for women. The standardized mortality rates of malignancy, cerebrovascular disease, heart disease and pneumonia were higher for men. In the final model of multivariate analysis for women, less than 6 hours of sleep [Hazard ratio (HR)=2.62] and lower social role (HR=1.88) significantly increased the risk of mortality. As for men, neither health behavioral items nor social role showed a significant association with mortality. CONCLUSIONS: Our study results suggest that having sufficient hours of sleep and enhancing social role could greatly help elderly women in Okinawa to maintain good health. Moreover, our study provides direction for future research to explore the difference in adequate health promotion measures between women and men.

Associated factors of rehospitalization among schizophrenic patients.

The purpose of the present study was to identify the associated factors of rehospitalization in schizophrenic patients. A case-control study was conducted. The cases consisted of rehospitalized patients (n = 67) and controls selected from the outpatients who were matched by age, gender, and the period after the last discharge (n = 62). In the multiple logistic regression analysis, no clinic visits in the second month prior to entry, the number of clinic visits in the previous month, and junior high school graduation as education level were significantly (P < 0.01) associated with rehospitalization after controlling their present function as assessed by the Global Assessment of Functioning. Close monitoring of clinic visits and outreach service appear to be important in preventing rehospitalization of schizophrenic patients. These identified modifiable factors suggest further needs for development and implementation of integrated mental health services in the community.

[Preventive strategy of fall for the prevention of fractures in older people: a review of the evidence].

This review aims to examine the effectiveness of fall-related strategies for fracture prevention among elderly population. Previous studies were reviewed using PubMed and Japan Centra Revuo Medicina databases. Our five research questions concerned prediction of fracture using history of accidental falls, fracture risk management, and effectiveness of exercise programs, home modification and usage of hip protector. We used "accidental falls" and "fractures" as search strategies. Obtained results were as follows: a) History of falls predicts future hip fracture. b) Exercise programs including balance training have positive effects for fracture prevention. c) Fracture risk evaluation and management reduce the number of hip fractures among elderly population. d) Environmental hazard assessment and necessary home modification are effective in preventing fractures especially among elderly population with the history of falls. e) The hip protector is a beneficial device for the prevention of hip fractures among elderly people at high risk of falling.

[Relationships between participation of national-health-insurance members in a health education program and exercise habits, medical expenses and other related parameters].

PURPOSE: This study was conducted with the aim of multi-faceted evaluation of a health education program, "Genki-jaya", run at Fukushima City Health and Welfare Center. METHODS: "Genki-jaya" is a health education program including individual health instructions combined with group education on exercises as well as diet. A total of 55 participants completed the program through December 1999 to March 2001. Twenty-six were under the medical care covered by national-health-insurance when the program started, and 19 of these, whose medical expenses for one month prior to the program were zero, were studied. The program was evaluated using the following: 1. Results of questionnaire surveys to examine self-care ability and perceived health conducted at the end of the program and three months after it finished. 2. Physical measurement items (blood pressure, weight, body fat rate, and BMI) and physical fitness items (maximum-oxygen-uptake, muscle-strength of legs, etc.) at the start of, and three months after the program. 3. Change in the total medical expenses between one year prior to and after the program, and its relationship with physical measurements and satisfaction with the program. Comparison of the mean three-month medical expenses before, during, and after the program. Comparison of medical expenses three months before, at the beginning and end of, and three months after the program. 4. Follow-up of continuous activities among graduates of the program. RESULTS: 1. Regarding self-care ability, dietary habits, and exercise habits, these continued to improve after the program and all participants were satisfied. Regarding perceived health, subjective symptoms improved. 2. Physical measurements improved through the program. Both mean diastolic pressure and body fat rate at the end of the program were significantly lower than at the beginning. Moreover, mean systolic and diastolic pressures significantly decreased from the end of the program through three months thereafter. 3. The medical expenses before and after the program did not change significantly, and differences did not correlate with physical measurements and satisfaction with the program. 4. Three self-supporting associations among the graduates had been organized to continue instructed exercises were active at the end of March 2001. CONCLUSION: Although Genki-jaya had no significant impact on medical expenses, improvement in self-care ability, perceived health, physical measurements and formation self-supporting associations was observed. Multi-faceted evaluation of the program will now be continued to examine larger numbers of newly enrolled trainees for a longer period of time.

[Effects of dietary variety on declines in high-level functional capacity in elderly people living in a community].

OBJECTIVE: The purpose of the investigation was to assess effects of dietary variety on declines in high-level functional capacity in community dwelling elderly, based on a 5-year longitudinal study (from 1992 to 1997). SUBJECTS AND METHOD: Subjects were a representative sample comprising 235 men (mean age 70.8 years) and 373 women (71.7 years) aged 65 years and above, living in Nangai village in Akita prefecture. Baseline and follow-up surveys were undertaken by the interview method. For assessing dietary variety, we introduced the dietary variety score (DVS), counting the number of 10 food-groups consumed daily from food frequency questionnaires: meat, fish and shellfish, eggs, milk, soybean products, potatoes, green yellow vegetables, fruits, seaweed, and fat and oil. The DVS ranged from 0 to 10 with higher score indicating a higher dietary variety. We also evaluated higher-level functional capacity using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG Index of Competence). Effects of dietary variety on declines in TMIG Index of Competence were analyzed by multiple logistic regression analysis. RESULTS: The average TMIG Index of Competence score for men and women were 12.1 and 10.8 at baseline, respectively. The mean baseline DVS was 6.3 for men, and 6.2 for women. Relative to the reference groups with DVS in 1-3, the groups with 4-8 and 9-10 scores had lower risks for decrease in TMIG Index of Competence scores over the study period. Relative risks (95% confidence interval) of the groups with a DVS of 4-8 and 9-10 were 0.92 (0.50-1.67) and 0.71 (0.34-1.48) regarding instrumental self maintenance, 0.50 (0.29-0.86) and 0.40 (0.20-0.77) for intellectual activities, and 0.44 (0.26-0.75) and 0.43 (0.20-0.82) for social roles of sub-scales of TMIG Index of Competence, adjusting for age, sex, educational attainment, and the baseline TMIG Index of Competence scores. CONCLUSION: Higher dietary variety is associated with a reduced risk of higher-level functional decline in community dwelling elderly.

[Epidemiology of falling].

It has been only some 10 years since the study of falls among old people was initiated in Japan. The incidence of falls depends on age, sex, health condition including underlying diseases, and extrinsic factors (e.g. living environment). The incidence of falls among community-dwelling elderly in Japan varies from approximately 10 to 25%, however, that among the elderly people in medical or care institutions is approximately 20 to 35%, being lower than that in US and European countries. The incidence of falls was higher in women than in men, and that it increased sharply with advancing age. Fall experience within one year preceding the survey was one of the major significant predicting factors. The available literature showed that exercise programs have beneficial effects. The exercises need to be regular and sustainable.
