Problem

Pacific Islanders are disproportionately burdened by poorer maternal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care.

Purpose

The purpose of this study was twofold: (1) to explore maternal health care providers’ perceptions and experiences of barriers in providing care to Marshallese women, and (2) providers perceived barriers of access to care among Marshallese women. This is the first paper to explore perceived barriers to maternal health care among a Marshallese community from maternal health care providers’ perspectives in the United States.

Methods

A phenomenological, qualitative design, using a focus group and in-depth interviews with 20 maternal health care providers residing in northwest Arkansas was chosen.

Findings

Several perceived barriers were noted, including transportation, lack of health insurance, communication and language, and socio-cultural barriers that described an incongruence between traditional and Western medical models of care. There was an overall discord between the collectivist cultural identity of Marshallese families and the individualistic maternal health care system that merits further research.

Discussion

Solutions to these barriers, such as increased cultural competency training for maternal health care providers and the incorporation of community health workers are discussed.  相似文献

Background

The association between sexual function and depression has yet to be examined in a prospective cohort study with prolonged postpartum follow-up.

Aim

We investigated whether sexual dysfunction predicted depressive symptoms during the 24-month postpartum period and examined the influence of obstetric factors.

Methods

This prospective 2-year cohort study with repeated measures included 196 participants who were recruited in a medical center in Taipei, Taiwan (2010–2011). Data on participants’ personal characteristics, sexual function, and depression symptoms at 4–6 weeks and at 3, 6, 12, and 24 months postpartum were collected and then assessed using the Female Sexual Function Index and the Center for Epidemiologic Studies Depression Scale.

Results

After adjusting for time and covariates, women with sexual dysfunction had a 1.62-fold (95% confidence interval [CI]: 1.05–2.50-fold) higher estimated odds ratio (OR) for depressive symptoms during the entire 24 months after childbirth than did women without sexual dysfunction. Risk factors for depressive symptoms were a higher pain score (OR: 1.33, 95% CI: 1.13–1.57), a medical condition (OR: 1.65, 95% CI: 1.00–2.73), and severe perineal laceration (OR: 4.67, 95% CI: 1.37–15.92). Sexual satisfaction during the entire 24 months after childbirth (OR: 0.81, 95% CI: 0.70–0.95) and the highest personal income level (OR: 0.33, 95% CI: 0.11–0.99) were factors protecting against higher-scoring depressive symptoms.

Conclusions

Our study provides robust evidence that sexual dysfunction and poor satisfaction, together with severe perineal laceration, greater pain, and a medical condition, predict depressive symptoms during the 24-month postpartum period.  相似文献

“戏剧何为”是曹禺剧作的批评者共同关注的焦点问题之一.耐人寻味的是,在不同历史阶段,研究者们于曹剧的思想价值与艺术价值之间总是有意无意地突出一方而非等而视之——要么肯定一方而否定另一方,要么将一方视为另一方的附属产品.这一现象首先与曹禺在个人创作倾向和时代、社会要求的冲突中所生发的价值犹疑有关——作者在“教育”和“娱情”两大功能之间的摇摆直接导致了其剧作价值倾向的模糊.更进一步说,由于戏剧自身的艺术特性及其不同于其他文类的受众特征,“教育”和“娱情”之间的角力始终潜隐于古今中外戏剧价值论内部,曹剧中两大功能之间的“暗斗”恰是其具体表现之一.  相似文献

《关于正确处理人民内部矛盾的问题》是毛泽东在我国社会主义建设早期,对马克思主义矛盾学说理论进行阐释的十分重要的经典著作之一.它的发表对于正确认识和处理我国社会主义建设时期的人民内部矛盾,提供了科学的理论遵循和方法借鉴,并产生了重大影响.学界近十年对《关于正确处理人民内部矛盾的问题》的研究,产生了大量的优秀理论成果,主要涉及文本的解读、历史的考察、哲学的思考、思政教育探析、当代价值、意义和启示等层面,但同时也存在一些问题,如研究视域相对狭小、研究深度相对不够、研究内容相对零碎、研究范式相对僵化、研究层面相对失衡等.学界需要在继承原有研究成果基础之上,扩大研究视野、创新研究范式、平衡研究层面,来促进《关于正确处理人民内部矛盾的问题》研究的不断深化.  相似文献

Health research traditionally has focused on the health risks and deficits of lesbian, gay, bisexual, transgender, and queer (LGBTQ) populations, obscuring the determinants that can promote health across the life course. Recognizing, appropriately measuring, and rendering visible these determinants of health is paramount to informing appropriate and engaging health policies, services, and systems for LGBTQ populations. The overarching purpose of this article is to provide an overview of the findings of a scoping review aimed at exploring strengths-based health promotion approaches to understanding and measuring LGBTQ health. Specifically, this scoping review examined peer-reviewed, published academic literature to determine (a) existing methodological frameworks for studying LGBTQ health from a strengths-based health promotion approach, and (b) suggestions for future methodological approaches for studying LGBTQ health from a strengths-based health promotion approach. The findings of this scoping review will be used to inform the development of a study aimed at assessing the health of and improving pathways to health services among LGBTQ populations in Nova Scotia, Canada.  相似文献

Demographic research has paid much attention to the impact of childhood conditions on adult mortality. We focus on one of the key aspects of early life conditions, sibling group size, and examine the causal effect of growing up in a large family on mortality. While previous studies have focused on low- or middle-income countries, we examine whether growing up in a large family is a disadvantage in Sweden, a context where most parents have adequate resources, which are complemented by a generous welfare state. We used Swedish register data and frailty models, examining all-cause and cause-specific mortality between the ages of 40 and 74 for the 1938–72 cohorts, and also a quasi-experimental approach that exploited multiple births as a source of exogenous variation in the number of siblings. Overall our results do not indicate that growing up in a large family has a detrimental effect on longevity in Sweden.  相似文献

This comparative social-historical study examines different versions of state-socialist body politics manifested in Hungary and Slovenia mainly during the 1950s by using archive material of “unnatural fornication” court cases. By analyzing the available Hungarian “természet elleni fajtalanság” and Slovenian “nenaravno ob?evanje” court cases, we can shed light on how the defendants were treated by the police and the judiciary. On the basis of these archive data that have never been examined before from these angles, we can construct an at least partial picture of the practices and consequences of state surveillance of same-sex-attracted men during state-socialism. The article explores the functioning of state-socialist social control mechanisms directed at nonnormative sexualities that had long-lasting consequences on the social representation of homosexuality in both countries.  相似文献

传统明瑟收入函数中收入取决于个人受教育程度、潜在市场工作经验和潜在市场工作经验平方项,其中受教育程度由受教育年限代表,不包含在校读书期间工作经验,然而,学生在毕业前往往能积累一定工作经验.因此,教育收益估计值包含了在校工作经验收益,导致教育收益估计值存在偏差.为了消除教育收益率估计偏差,使用哈尔滨市就业市场问卷调查数据,估算了两个收入方程——含在校工作经验变量的收入方程和不含有在校工作经验变量的收入方程.估算结果显示,后者较前者在教育投资回报系数上高出28%-44%(取决于对能力偏差的控制程度),这些结果表明传统明瑟收入函数过分夸大了个人受教育程度对收入的影响.  相似文献
