     概要を見る

    OBJECTIVE: To evaluate how cardiovascular diseases harm labor force participation (LFP) among the Japanese population and verify the validity of plasma biomarkers as instrumental variables of cardiovascular diseases after adjusting for a broad set of confounders including dietary intake. DESIGN: Using nationally representative repeated cross-sectional surveys in Japan, the Comprehensive Survey of Living Conditions and National Health and Nutrition Survey, with plasma biomarkers as instrumental variables for quasi-randomization. SETTING: Onset of cardiovascular diseases in those receiving regular treatment for hypertension, intracerebral hemorrhage, intracerebral infarction, angina pectoris, myocardial infarction, or other types of cardiovascular diseases. PARTICIPANTS: A total of 65,615 persons aged ≥ 20 years (35,037 women and 30,578 men) who completed a survey conducted every three years from 1995 through 2013. MAIN OUTCOME MEASURES: Respondent employment and weekly working hours during each survey year. RESULTS: Cardiovascular diseases significantly and remarkably reduced the probability of working by 15.4% (95% CI: -30.6% to -0.2%). The reduction in working probability was detected for women only. Respondents aged ≥ 40 years were less likely to work once diagnosed and the reduction was enlarged for those aged ≥ 65 years, while those aged < 40 years appeared to be unaffected. Probability of engaging in manual labor significantly decreased once diagnosed; however, no impact was found for cognitive occupations. Among employed respondents, the adverse effects of cardiovascular diseases decreased working hours by five hours per week. Validity of the biomarker instrumental variables was generally verified. CONCLUSIONS: A vicious circle is suggested between LFP and unfavorable health. However, the effects vary across age, sex, and occupation type, even after adjusting for causal effects, which could cause a downward bias in LFP impact. ATTRIBUTES: cardiovascular disease, labor force participation, instrumental variable method as quasi-randomization, plasma biomarker, Comprehensive Survey of Living Conditions, National Health and Nutrition Survey.

  • Does the positive relationship between health and marriage reflect protection or selection? Evidence from middle-aged and elderly Japanese

    Rong Fu, Haruko Noguchi

    Review of Economics of the Household     1 - 14  2018年03月  [査読有り]

    担当区分:筆頭著者, 責任著者

     概要を見る

    This study investigates the marriage protection and selection effects among middle-aged and elderly Japanese. Using 9 years of a longitudinal data set from a nationally representative survey in Japan from 2005 to 2013, we extract 15,242 respondents aged 50–59 years in the baseline year. We utilize positive self-rated health to present subjective health status and lifestyle diseases to present objective health status. Using dynamic panel data approach to control for endogeneity issue, we find that being married does protect respondents’ subjective health, in terms of a higher probability of self-ratings of “very good” or “good” health statuses. Nonetheless, we find that marriage deteriorated their objective health in terms of a higher probability of having lifestyle diseases. Regarding the selection effect, better subjective health is found to select middle-aged and elderly Japanese into marriage, but such influence is fairly modest. Although objective health status also selects respondents into marriage, it positively affects women but adversely affects men. The findings provide a more comprehensive understanding of the relationship between marriage and health, which may have substantial implications for health-related public policies for middle-aged and elderly people in Japan.

  • Spillover effect of Japanese long-term care insurance as an employment promotion policy for family caregivers

    Rong Fu, Haruko Noguchi, Akira Kawamura, Hideto Takahashi, Nanako Tamiya

    Journal of Health Economics   56   103 - 112  2017年12月  [査読有り]

    担当区分:筆頭著者, 責任著者

     概要を見る

    We evaluate a spillover effect of the Japanese public long-term care insurance (LTCI) as a policy to stimulate family caregivers’ labor force participation. Using nationally representative data from 1995 to 2013, we apply difference-in-difference propensity score matching to investigate the spillover effect in two periods: before and after the introduction of the LTCI in 2000 and before and after its major amendment in 2006. Our results show that the LTCI introduction has significant and positive spillover effects on family caregivers’ labor force participation and the effects vary by gender and age. In contrast, the LTCI amendment is found to have generally negative spillover effects on their labor force participation. We draw attention to these spillover effects, as expanding labor market supply to sustain the economy would be a priority for Japan and other rapidly aging countries in the coming decades.

  • Relation between social network and psychological distress among middle-aged adults in Japan: Evidence from a national longitudinal survey

    Rong Fu, Harkuo Noguchi, Hirokazu Tachikawa, Miyuki Aiba, Shin Nakamine, Akira Kawamura, Hideto Takahashi, Nanako Tamiya

     概要を見る

    It is widely documented that psychological distress is negatively associated with social networks involvement. However, despite the theoretical postulations that social networks are crucial for alleviating psychological distress, no study has yet empirically confirmed the causality of this relationship. Thus, we used the random-effects generalized least squares method to investigate the effect of one- and two-year lagged values for involvement in social networks on psychological distress. Nine years of longitudinal data were extracted from a nationally representative survey in Japan ("The Longitudinal Survey of Middle-aged and Older Persons"). We utilized the Kessler 6 (K6) score to measure psychological distress among 15,242 respondents aged 50-59 years in the baseline year (2005), and stratified participants into three layers of social networks: inner (well-established friendship ties and participating in hobby activates), intermediary (neighborly ties), and outer (involvement in community activities). We found highly significant and negative associations between all three layers and K6 scores, with the strongest association being for the inner layer. We further observed that one-year lagged involvement in the inner and intermediary layers led to significantly lower K6 scores. However, the protective influences of social networks generally diminished over time. In addition, the protective influences of social network involvement on psychological distress were stronger for women than for men. Furthermore, involvement in social networks was especially important for improving mental health among people with psychological distress. These findings would be important for policymaking to prevent mental health deterioration among middle-aged adults in Japan. (C) 2017 Elsevier Ltd. All rights reserved.

  • Does Marriage Make Us Healthier? Inter-Country Comparative Evidence from China, Japan, and Korea

    Rong Fu, Haruko Noguchi

    PLOS ONE   11 ( 2 )  2016年02月  [査読有り]

    担当区分:筆頭著者, 責任著者

     概要を見る

    Objectives
    This study focuses on East Asian countries and investigates the difference in the marriage premium on the health-marriage protection effect (MPE) between younger and older generations and the intra-couple education concordance effect (ECE) on the health of married individuals. This study used inter-country comparative data from China, Japan, and Korea.
    Methods
    This study focused on individuals (n = 7,938) in China, Japan, and Korea who were sampled from the 2010 East Asian Social Survey. To investigate MPE and ECE, four health indicators were utilized: a physical and mental components summary (PCS and MCS), self-rated health status (Dself), and happiness level (Dhappy). Ordinary least squares regression was conducted by country-and gender-specific subsamples.
    Results
    We found that the MPE on PCS, MCS, and Dself was more significant for the older generation than for the younger generation in both China and Japan, whereas the results were inconclusive in Korea. With regard to the ECE on happiness (Dhappy), for both men and women, couples tend to be happier when both the husband and the wife are well educated ("higher balanced marriage") compared to couples with a lower level of educational achievement ("lower balanced marriage"). Significant benefits from a "higher balanced marriage" on MCS and Dself were observed for women only. In contrast, no statistically significant differences in health status were observed between "higher balanced marriage" couples and couples with different levels of educational achievements ("upward marriage" or "downward marriage").
    Conclusions
    This study found that (1) the MPE was more significant for the older generation, and (2) the health gap, particularly the happiness gap, between higher-and lower-balanced married couples was significant. The inter-country comparative findings are useful to explain how the role of marriage (and therefore of family) on health has been diluted due to the progress of industrialization and modernization.

     概要を見る

    In 2019, the research emphases were loaded to the construction of datasets and medical costs effect of the DPC/PDPS. By appropriate extracting and collating, datasets were settled down in June. During the process, we also summarized basic statistics for investigations on medical costs, LOS, and healthcare quality, respectively. Briefly, we found that healthcare providers responded opportunistically to the reform, moving some procedures out of the bundled inpatient setting to FFS cares, leading to no reduction in cost. There was some evidence of a deterioration in health outcomes, though mortality was not affected. In sum, the results suggest that in some cases, a hybrid payment system can be non-superior to either FFS or prospective payment system. We presented the results at international Health Economics Association and drafted the manuscript for publication.

     概要を見る

    国民介保険は被用者以外の多様な生活(雇用)形態にある者に対して医療アクセスを保障する機能を持つ。超高齢・人口減少の状態にあっても支払い可能な保険料でその機能が維持されることは重要である。本研究では、加入・利用しやすい公的医療保険制度の持続を目指して、医療費の負担のあり方、日本における保険制度・保険者のあり方について、データを用いた実証分析を行い、その結果を踏まえた上で検討を行った。
    低い所得階級において社会保険料負担が軽減されつつも、必ずしもそれが未納率を改善する効果を持ち得ていない可能性がある一方、高額療養費制度により医療サービス利用へのアクセスは保証されている可能性が示唆された。

  • The effect of nonproprietary name prescription on the adoption of generic drugs: evidence from cardiovascular drugs

    2020年  

     概要を見る

    We use all claim records related to the utilizationof cardiovascular agents (i.e., all agents with&nbsp;薬効分類コード211-219) from April 2009 to March 2019. Weplan to construct a medical institution-patient-month panel dataset. For eachyear between 2009 and 2019, we focus on drugs with multisource up to date (i.e.,both brand-name and generic versions are available). For each brand-name drug,we pair at least one generic drug to it with the same dosage form and strength. There are three possible pairs for a specific class of drugs, i.e., beta-blockers.Pair I contains three drugs: a brand-name tablet with strength at 20mg, and twogeneric-version tablets with the same strength. Essentially, a pair can havemore than two brand-name/generic drugs. Pair II differs from Pair I, despitethe same strength (20mg), because of the different dosage form (capsule). PairIII differs from Pair II, despite the same dosage form (capsule), because thestrength of the brand name is 10mg. Thus, there could be multiple pairs for aspecific class of drugs.

  • A Comprehensive Evaluation of the Hospital Payment System in Japan

    2020年  

     概要を見る

    Countries seeking to move away from a purely fee‐for‐service (FFS) systemmay consider a hybrid approach whereby only some procedures are paid byFFS while others are paid prospectively. Yet little evidence exists whether sucha hybrid payment system contains overall costs without adverse influences onhealth outcomes. In 2003, Japan experienced a reform from FFS to a hybridpayment system in which only some inpatient procedures were paid prospectively.We exploit this reform to test how such a hybrid system affectsoverall costs and health outcomes. Briefly, we find that healthcare providersresponded opportunistically to the reform, moving some procedures out of thebundled inpatient setting to FFS services, leading to no reduction in cost.There was some evidence of a moderate deterioration in health outcomes, interms of a decline in the probability of symptoms being cured at discharge. Insum, our results suggest that in some cases, a hybrid payment system can benon‐superior to either FFS or a prospective payment system.

  • Cost,Length of Stay,and Health Outcome:A comprehensive evaluation of Prospective Payment System in Japan

    2019年   Haruko Noguchi, Yichen Shen

     概要を見る

    In 2003, Japan experienced a reform from the fee-for-service system to the blended payment system, a system where only some procedures within inpatient care are required to be paid with the prospective payment system. Exploiting the reform, we investigate the impact of the blended payment system on cost and health outcomes. Using 1997 to 2010 health insurance claims, we show that the blended payment system does not cost less than the fee-for-service system and induces health deteriorations. The deteriorations in health are moderate in comparison with the prospective payment system. The failure to contain cost and the deterioration of health is driven by providers' compensation seeking behaviors that cause a shift of procedures paid via prospective payment system to procedures paid via the fee-for-service system. Our findings point to further reform of the blended payment system to restrict provider incentive to seeking compensations.
