Validity and reproducibility of folate and vitamin B12 intakes estimated from a self-administered diet history questionnaire in Japanese pregnant women

<p>Abstract</p> <p>Background</p> <p>No validated dietary questionnaire for assessing folate and vitamin B₁₂intakes during pregnancy is available in Japan. We evaluated the validity and reproducibility of intakes of folate and vitamin B₁₂estimated from a self-administered diet history questionnaire (DHQ) in Japanese pregnant women.</p> <p>Methods</p> <p>A sample of 167 healthy subjects with singleton pregnancies in the second trimester was recruited at a private obstetric hospital in metropolitan Tokyo from June to October 2008 (n = 76), and at a university hospital in Tokyo from June 2010 to June 2011 (n = 91). The dietary intakes of folate and vitamin B₁₂were assessed using the DHQ. The serum concentrations of folate and vitamin B₁₂were measured as reference values in the validation study. To assess the reproducibility of the results, 58 pregnant women completed the DHQ twice within 4-5 week interval.</p> <p>Results</p> <p>Significantly positive correlations were found between energy-adjusted intakes and serum concentrations of folate and vitamin B₁₂(r = 0.286, <it>p </it>< 0.001 and r = 0.222, <it>p </it>= 0.004, respectively). After excluding the participants with nausea (n = 121), the correlation coefficient for vitamin B₁₂increased to 0.313 (<it>p </it>= 0.001). When participants were classified into quintiles based on intakes and serum concentrations of folate and vitamin B₁₂, approximately 60% were classified in the same or adjacent quintile. The intraclass correlation coefficients of the two-time DHQ were 0.725 for folate and 0.512 for vitamin B₁₂.</p> <p>Conclusion</p> <p>The present study indicated that the DHQ had acceptable validity and reproducibility for assessing folate and vitamin B₁₂intakes in Japanese pregnant women.</p

Long-Term Care Insurance in Japan: Its Frameworks, Issues and Roles

In response to an increase in the number of elderly people and increasing medical costs, the Japanese government implemented the Long-Term Care Insurance (LTCI) system for the elderly in April 2000. Three years have passed since the LTCI was initiated. The purpose of this paper is to describe the framework, current situation and issues of this system, and the challenges and roles of the LTCI in the future. The numbers of service agencies, institutions, and LTCI service users have been steadily increasing. The waiting list for institutions has also increased, and only half of the users have reached the upper cost limit. Most users were satisfied with the LTCI services. However, the decisions made by the elderly on the types of services to use within the LTCI system are sometimes influenced by their families. The system has some problems regarding the lack of support that is provided to the elderly with respect to their access, choice and use of the LTCI services. Often, care managers cannot devote enough time to the care management process. As a result, important elements of care management, such as conducting home visits to assess users Although there have been amendments to the system, several challenges of the LTCI system must be considered: (i) ensuring the future financing of LTCI services is met; (ii) providing countermeasures to promote the use of home-care services and to alleviate the care burden to family caregivers; (iii) providing adequate support and advocacy of rights and decision-making for the elderly; (iv) providing educational activities to disseminate knowledge about LTCI programs; and (v) ensuring the availability of activities to promote health for the elderly and to prevent them from becoming bedridden.Elderly, Health-policy, Healthcare-expenditure, Reimbursement

The effects of an intervention program for promoting interorganizational network building between multidisciplinary agencies and community-based organizations: a cluster trial in Japan

Abstract Background Strengthening interorganizational relationships in the community has become an increasingly valued strategy for improving public health in recent years. However, no intervention strategy to foster an interorganizational network in the community has yet been devised. The purpose of this study was to examine the effects on members of an organization of an intervention program designed to promote interorganizational network building between multidisciplinary agencies and community-based organizations (CBOs). Methods The program was conducted in Setagaya and Suginami wards, Tokyo, Japan, for staff of community comprehensive support centers (CCSCs), which are multidisciplinary organizations responsible for the support of the elderly. A cluster non-randomized design with a CCSC as a cluster unit (N = 47) was used. The intervention group comprised 20 centers and the control group 27 centers. Those 27 centers declined to participate in program sessions, but did participate through completing pre- and post-intervention surveys. In total, 158 staff members were eligible to participate in this study, 73 from the intervention group and 85 from the control group. Of the 73 members in the intervention group, 19 participated in the monthly program sessions, over a period of 10 months. Attendees participated in group discussions during the sessions. The effects of the intervention were examined by comparing three groups (attendees and non-attendees of the program from the intervention group, and the control group) and between two groups (intervention group and control group). Results We found no significant difference in any outcome between the intervention group and the control group. However, among the three groups, a significant effect was found in the recognition of knowledge and skills for building networks with CBOs. Recognition of knowledge and skills increased significantly among the attendees compared to non-attendees in the intervention group and the control group. In addition, there was a significant effect, particularly on those with relatively low baseline scores, for the recognition of knowledge and skills. Conclusions The tested intervention proved effective for attendees regarding their recognition of knowledge and skills for promoting interorganizational network building with CBOs.</p

Association between Municipal Health Promotion Volunteers’ Health Literacy and Their Level of Outreach Activities in Japan

<div><p>Objectives</p><p>To explore the association between health literacy and levels of three types of core activities among health promotion volunteers (developing a healthy lifestyle, outreach to family, and outreach to community members).</p><p>Study Design</p><p>A cross-sectional, anonymous, self-administered postal survey of registered health promotion volunteers in the Konan area in Shiga Prefecture in Japan, conducted in January 2010. The study sample was 575 registered health promotion volunteers.</p><p>Methods</p><p>The survey collected data on health literacy, gender, age, education, self-rated health, perceptions about the volunteer organization, and perceptions of recognition in the community. The level of engagement in health promotion activities was measured by the extent to which the participants engaged in seven healthy behaviors and promoted them to family members and the community. The authors compared the health literacy level and other characteristics of the participants by core health promotion activities, using a chi-squared test, to examine the associations between demographic and other variables and the three core activities (healthy lifestyle, outreach to family, and outreach to community).Logistic regression analysis was conducted to examine the association between the degree to which the volunteers engaged in core activities (“healthy lifestyle,” “outreach to family,” “outreach to community”) and the levels of health literacy (low, medium, high) among health promotion volunteers, controlling for the effects of age, gender, health condition, education which may also have an impact on volunteers’ outreach activities.</p><p>Results</p><p>Four hundred and fifty-four questionnaires were returned, a 79.0% response rate. Excluding 16 cases with missing values on health literacy or the degree of health promotion activities, 438 research subjects were included in the analysis (valid response rate: 76.2%). Health literacy and a few demographic and other characteristics of the volunteers were associated with the three core health promotion activities. In bivariate analyses, active participation in the core activities was more prevalent among older volunteers (p<0.001 for all three activities). Self-rated health condition was associated with both outreach to family (p = 0.018) and community (p = 0.046). Years of experience as volunteer and perception of being recognized in the community also had statistically significant association with outreach to the community (p<0.001). In multiple logistic regression, those with higher level of health literacy were more likely than others to actively engage in outreach to family (OR = 1.70, 95% CI 1.03 to 2.80; OR = 1.76, 95%CI 1.04 to 3.00 for medium and high, respectively) and outreach to community (OR = 2.26, 95%CI 1.34 to 3.83; OR = 2.61 95%CI 1.49 to 4.58 for medium and high, respectively). Perception of being recognized in the community also had a statistically significant and positive impact on outreach to the community (OR = 1.52, 95%CI 1.17 to 1.99).</p><p>Conclusions</p><p>Volunteers with higher health literacy were more likely to actively engage in outreach to family and outreach to community. Providing educational programs to improve volunteers’ health literacy may facilitate their work.</p></div

Healthcare costs for the elderly in Japan: Analysis of medical care and long-term care claim records.

The population is aging rapidly in many developed countries. Such countries need to respond to the growing demand and expanding costs of healthcare (HC) for the elderly. Therefore, it is important to investigate the factors correlating such HC costs. In Japan, HC is composed of two sections, namely medical care (MC) and long-term care (LTC). While many studies have examined MC and LTC costs on their own, few studies have conducted comprehensive investigations of HC costs. The aim of this study is to examine the risk factors that influence HC costs for the elderly who enroll in the LTC insurance system in Japan.The inclusion criteria in the present study are as follows: being 65 years of age, or older; certified eligibility for, and use of services offered by the LTC insurance system at home or in an institutional setting in December 2009; and being covered by the National Health Insurance (NHI) system. MC and LTC insurance data were obtained from claim records for the elderly in July and December of 2007, 2008, and 2009 (i.e., a total of six survey points). Panel data, per subject, were constructed using MC and LTC claim records. The sample included 810 subjects and 4029 observations.We estimated a regression equation with a censored dependent variable using a Tobit model. Significant associations between MC or LTC costs and interaction terms (household composition × seasonal effects) were investigated. MC costs significantly decreased and LTC costs significantly increased among subjects living alone during winter. Income level was also a positive determinant of MC costs, while eligibility level was a positive determinant of LTC costs.We recommend that the health policy for the elderly focus more on seasonal effects, household composition, and income level, as well as on eligibility level

Identification of the need for home visiting nurse: development of a new assessment tool

Objective: To develop a Home Visiting Nursing Service Need Assessment Form (HVNS-NAF) to standardize the decision about the need for home visiting nursing service.Methods: The sample consisted of older adults who had received coordinated services by care managers. We defined the need for home visiting nursing service by elderly individuals as the decision of the need by a care manager so that the elderly can continue to live independently. Explanatory variables included demographic factors, medical procedure, severity of illness, and caregiver variables. Multiple logistic regression was carried out after univariate analyses to decide the variables to include and the weight of each variable in the HVNS-NAF. We then calculated the sensitivity and specificity of each cut-off value, and defined the score with the highest sensitivityand specificity as the cut-off value.Results: Nineteen items were included in the final HVNS-NAF. When the cut-off value was 2 points, the sensitivity was 77.0%, specificity 68.5%, and positive predictive value 56.8%.Conclusions: HVNS-NAF is the first validated standard based on characteristics of elderly clients who required home visiting nursing service. Using the HVNS-NAF may result in reducing the unmet need for home visiting nursing service and preventing hospitalization
