    Background: Menstrual symptoms have been identified as a substantial burden among women of reproductive age, affecting their health status and quality of life globally. A range of menstrual symptoms have been studied as they affect the health-related quality of life (HRQoL), showing variations across specific menstrual symptoms and study settings. A major concern is demonstrated due to menstrual symptoms in women’s professional and social life, and consequently societal and economic loss for women and the society at large. Yet evidence is scarce that estimates the index form HRQoL score related to menstrual symptoms that is needed for health economic evaluations. Methods: This study aims to investigate the association between menstrual symptoms and the HRQoL among working women in Japan in an index form, using a self-reporting questionnaire (n = 6048). The EQ-5D-3L (EuroQoL 5-dimension 3-level) is used that is a widely used tool to measure health outcomes for health economic evaluations globally. Multivariate regression analysis is conducted to assess the association between the HRQoL score and specific nineteen physical and mental conditions related to menstruation (e.g., pain, heavy bleeding, concentration, negative affect). Results: The index form HRQoL score for menstrual symptoms is estimated as 0.682 in the study population (where a score one suggests perfect health). The association of the HRQoL score varies substantially across the menstrual symptoms. Several of the physical conditions and disorders show a substantial negative association with the HRQoL score. Also, most of the mental and psychological issues are significantly and negatively related to the HRQoL score. Conclusions: This study suggests that HRQoL is substantially and negatively affected by menstruation among working women in Japan. Distinct variations of negative influences across menstrual symptoms underscore the multi-dimensional nature of menstruation and consequently the need of collective interventions to address these difficulties. The evidence of HRQoL continues to be an important area for future research on women’s health and health economic evaluations to inform effective and efficient resource allocations for relevant health policies and financing strategies.

    Introduction The rapid spread of COVID-19 posed a global burden. Substantial number of people died of the disease in the acute phase of infection. In addition, a significant proportion of patients have been reported to suffer from post-acute phase symptoms, sequelae of COVID-19, which may negatively influence the quality of daily living and/or socioeconomic circumstances of the patients. However, no previous study has comprehensively and objectively assessed the quality of life of patients by using existing international scales. Further, evidence of socioeconomic consequences among patients with COVID-19 is scarce. To address the multidimensional issues from sequelae of COVID-19, evidence from comprehensive surveys beyond clinical perspectives is critical that investigates health, and social determinants of disease progression as well as socioeconomic consequences at a large scale. Methods and analysis In this study, we plan to conduct a nationwide and comprehensive survey for the sequelae of COVID-19 in a total of 1000 patients diagnosed at 27 hospitals throughout Japan. This study will evaluate not only the health-related status of patients from clinical perspectives but also the Health-related Quality of Life (HRQoL) scores, socioeconomic status and consequences to discuss the sequelae of the disease and the related risk factors. The primary endpoint is the frequency of long-term complications of COVID-19 infection. The secondary endpoints are risk factors for progression to sequelae of COVID-19 infection. The study will provide robust and important evidence as a resource to tackle the issues from the sequelae of COVID-19 from the multi-dimensional perspectives. Ethics and dissemination This trial was approved by the Keio University School of Medicine Ethics Committee (20200243, UMIN000042299). The results of this study will be reported at a society meeting or published in a peer-reviewed journal.

     概要を見る

    Maternal and newborn mortality remain unacceptably high in sub-Saharan Africa where use of a skilled birth attendant (SBA) at delivery has remained low. Despite the recognized importance of women's empowerment as a key determinant of maternal and newborn health, evidence from sub-Saharan Africa is more limited. Using data from the 2010 Tanzania Demographic and Health Survey (n = 4,340), this study employs a robust method-structural equation modeling (SEM)-to investigate the complex and multidimensional pathways through which women's empowerment affects SBA use. The results show that women's education and household decision-making are positively associated with SBA use. However, not all empowerment dimensions have similar effects. Attitudes towards sex negotiation and violence as well as early marriage are not significant factors in Tanzania. Mediation analysis also confirms the indirect effect of education on SBA use only through household decision-making. The findings underscore the utility of structural equation modeling when examining complex and multidimensional constructs, such as empowerment, and demonstrate potential causal inference to better inform policy and programmatic recommendations.

    Background: Despite the reduction in maternal deaths globally, maternal mortality rates remain unacceptably high, particularly in some regions of the world. In sub-Saharan Africa, maternal mortality rates have even increased recently, with 201,000 deaths in 2015 as compared to 179,000 in 2013. Use of a skilled birth attendant (SBA) at delivery has remained low, despite evidence of the effectiveness of SBAs in reducing maternal deaths. Women's empowerment is increasingly recognized as a key determinant of maternal health care-seeking and outcomes, yet empirical examinations of the linkages between women's empowerment and delivery care use are particularly limited, especially from sub-Saharan Africa. Methods: Using data from the 2010 Senegal Demographic and Health Survey (n = 7451), in this study we employed structural equation modeling (SEM) to investigate the complex and multidimensional pathways by which three women's empowerment domains (household decision-making, attitudes towards violence, and sex negotiation) directly and indirectly affect SBA use. Results: Although variations were observed across measures, many of the women's status and empowerment measures were positively related to SBA use. Notably, women's education demonstrated a substantial indirect effect: higher education was related to older age at first marriage, which was associated with higher levels of empowerment and SBA use. In addition to age at first marriage, gender-role attitudes (e.g., progressive attitudes towards violence and sex negotiation) were significant mediators in the relationship between education and SBA use. However, household decision-making was not significantly associated with SBA use. Conclusions: Findings indicate significant effects of women's education, early marriage, and some dimensions of women's empowerment on SBA use. SEM was particularly useful in examining the complex and multidimensional constructs of women's empowerments and their effects. This study informs policy recommendations and programmatic efforts to reduce maternal mortality in sub-Saharan Africa by strengthening support for women's access to higher education, delaying marriage and childbearing among girls and young women, and supporting more equitable gender norms.

  • The relationship of women's status and empowerment with skilled birth attendant use in Senegal and Tanzania

    Background: Maternal mortality remains unacceptably high in sub-Saharan Africa with 179,000 deaths occurring each year, accounting for 2-thirds of maternal deaths worldwide. Progress in reducing maternal deaths and increasing Skilled Birth Attendant (SBA) use at childbirth has stagnated in Africa. Although several studies demonstrate the important influences of women's status and empowerment on SBA use, this evidence is limited, particularly in Africa. Furthermore, few studies empirically test the operationalization of women's empowerment and incorporate multidimensional measures to represent the potentially disparate influence of women's status and empowerment on SBA use across settings. Methods: This study examined the relationship of women's status and empowerment with SBA use in two African countries - Senegal and Tanzania - using the 2010 Demographic and Health Surveys (weighted births n = 10,688 in SN; 6748 in TZ). Factor analysis was first conducted to identify the structure and multiple dimensions of empowerment. Then, a multivariate regression analysis was conducted to examine associations between these empowerment dimensions and SBA use. Results: Overall, women's status and empowerment were positively related to SBA use. Some sociodemographic characteristics showed similar effects across countries (e.g., age, wealth, residence, marital relationship, parity); however, women's status and empowerment influence SBA use differently by setting. Namely, women's education directly and positively influenced SBA use in Tanzania, but not in Senegal. Further, each of the dimensions of empowerment influenced SBA use in disparate ways. In Tanzania women's higher household decision-making power and employment were related to SBA use, while in Senegal more progressive perceptions of gender norms and older age at first marriage were related to SBA use. Conclusions: This study provides evidence of the disparate influences of women's status and empowerment on SBA use across settings. Results indicate that efforts to increase SBA use and to reduce maternal mortality through the improvement of women's status and empowerment should focus both on improving girls' education and delaying marriage, as well as transforming gender norms and decision-making power. However, given the multi-dimensional and contextual nature of women's status and empowerment, it is critical to identify key drivers to increase SBA use in a given setting for contextually tailored policy and programming.
