The level of education and other adult socioeconomic characteristics of men are known to associate with their fertility, but early-life socioeconomic characteristics may also be related. We studied how men’s adult and early-life socioeconomic characteristics are associated with their eventual fertility and whether the differences therein by educational level are explained or mediated by other socioeconomic characteristics. The data on men born in 1940–1950 (N = 37,082) were derived from the 1950 Finnish census, which is linked to later registers. Standard and sibling fixed-effects Poisson and logistic regression models were used. Education and other characteristics were positively associated with the number of children, largely stemming from a higher likelihood of a first birth among the more socioeconomically advantaged men. The educational gradient in the number of children was not explained by early socioeconomic or other characteristics shared by brothers, but occupational position and income in adulthood mediated approximately half of the association. Parity-specific differences existed: education and many other socioeconomic characteristics predicted the likelihood of a first birth more strongly than that of a second birth, and the mediating role of occupational position and income was also strongest for first births. Relatively small differences were found in the likelihood of a third birth. In men, education is positively associated with eventual fertility after controlling for early socioeconomic and other characteristics shared by brothers. Selective entry into fatherhood based on economic provider potential may contribute considerably to educational differentials in the number of children among men.  相似文献

Recently, researchers have reported high musculoskeletal symptom prevalence at several US colleges. Since ergonomic interventions have been shown to prevent and reduce disability, it is important to identify the risk factors for developing symptoms among college students. A nested case-control study was completed to determine computer-related ergonomic risks associated with musculoskeletal symptoms. A trained observer completed ergonomic assessments on 52 randomly selected cases and controls. More than 75 percent (cases and controls combined) of the population was exposed to nine potential postural strains including: arms not along side during keying or mousing; lower back not supported; not having chair accessories; computer monitor not adjustable; mouse being too high or low; hand/wrist/forearm in contact with the desk edge; lack of wrist support; and keyboard not being adjustable. Cases and controls were equally likely to have substantially elevated risks but because the sample was small and lacked power, no risks were statistically significant. Since many known risk factors were prevalent in cases and controls, more research is required to evaluate and prevent injury in this population.  相似文献

The influence of generational structure on well-being in mid-life is examined in a regional representative sample of 807 adults aged 30–64. Results indicate that those who lack the personal and social resources of education and marriage, and have parents but no children, report higher levels of well-being than those with only child(ren) or both parent(s) and child(ren). Findings suggest that elders may serve as a key resource to adult children who lack personal and social resources in mid-life. Adults increasingly follow less traditional paths in life (e.g., those without children and/or never married), and hence, these findings have implications for current and future policies directed toward aging and family well-being.  相似文献

Abstract

This study assessed the gender differences in determinants of fair/poor self-rated health among African American churchgoers in Omaha, Nebraska. Using data collected from 353 African American (245 women and 108 men) by the Center for Reducing Health Disparities at the University of Nebraska Medical Center in 2017, univariate and multivariate logistic regressions were performed to examine the gender differences in the relationships between fair/poor self-rated health and potential health determinants. Overall, 14.3% of women and 17.6% of men reported fair/poor self-rated health. There was a significant association between depression and poor/fair self-rated health among women (p?=?0.044) and men (p?=?0.001). For women, the fully controlled model confirmed the crude association between perceived poor/fair self-rated health and heart disease (OR = 3.10) and education (OR = 2.19). For men, the final model identified significant determinants of perceived fair/poor self-rated health such as depression (OR = 12.51) and diabetes (OR = 3.89). When assessing gender differences in determinants of self-rated health, similarities are higher than differences between the two groups. In both groups, the presence of depression was the strongest determinant of poor health. Future research should assess the immunological aspects of the association between psychological factors and perceived chronic diseases.  相似文献

The importance of maternal education for children's academic outcomes is widely recognized, and yet the multiple potential mechanisms that explain this relationship are underexplored. The authors integrate theories of human, cultural, and social capital with 2 developmental psychology theories—bioecological theory and developmental niche theory—to draw attention to how maternal education may influence children's academic outcomes through a range of parenting mechanisms, some of which have been largely neglected in research. This framework provides a more complete picture of how maternal education shapes proximal and distal influences on children's academic outcomes and the ways in which these mechanisms interact and reinforce one another across time and context. The implications of this framework for future family research are then discussed.  相似文献

This article examines the relationship between biosocial meanings of aging and anti‐aging culture, whereby new standards of measuring age derive from nonchronological models of plasticity. The first part explores recent models of functional age, sexual performance, and cognitive health, while the second part outlines the cosmetic rejuvenation practices, discourses, and technologies of medi‐spa clinics that promise to repair the effects of time on the bodies of aging women. Both parts illustrate the sociological significance of the aging body in posttraditional society as the object of increasing public anxieties about the health of aging populations and ethical concerns for extending life.  相似文献

This study investigated whether self-identified disabilities among American Indian and Alaskan Native college students impact academic performance and persistence to graduation and explored the differences in health and academic grades between American Indian and Alaskan Native students and students of other racial and ethnic identities using the National College Health Assessment. Findings indicate that American Indian or Alaskan Native students have significantly lower grades than White and Asian students, and American Indian and Alaskan Native women report the highest incidence of health problems of any demographic group. Exploratory results point to future research to determine the full impact of disabilities and poor health on academic success.  相似文献

全球范围内城市聚落的增长影响着人类对自然资源的管理,从而促使自然科学和社会科学的学者们提倡以基于生态系统的途径来管理人类聚落。尽管过往有不少探讨基于生态系统管理(ecosystem-based management,以下简称EBM)的文献,但在制定环境政策时,却极少有城市和区域规划师将EBM因素考虑在内。本文对西华盛顿州的城市规划师在审视关于环境政策的科研数据时,在多大程度上运用EBM原则进行评估。笔者采用了现成文献中对EBM的定义,采访了42位在西华盛顿工作的环境规划师,询问其在审视有关科研数据时会考虑哪些EBM因素,并对访谈数据进行内容分析。结果显示,规划师们在审视与制定环境政策相关的科学文献时,会考虑监测、机构间合作、生态边界、价值取向乃至适应性管理等因素,但对于尺度、生态完整性和机构改革等因素,则会遇到阻碍或者说不会明确考虑。本文还阐述了为何有些EBM因素得到重视而另一些却被忽略,最后对通过应用EBM原则来改良城市环境政策的制定提出了建议。  相似文献

The important relationship between fertility rates and economic development has prompted many researchers to try and better understand the determinants of family size. It has repeatedly been shown that the costs of children, both direct and indirect, are one of the most important determinants of fertility, exerting a significantly negative effect on birth rates in both developed and developing countries. Many studies which investigate the relationship between the costs of children and family size have assumed that these costs do not vary with parity. However, there is substantial evidence that the marginal costs of children are not constant but decrease with birth order in developed countries. In this paper, the hypothesis that there are diminishing marginal time costs of children is tested using household data from the developing country setting of the Philippines. By examining the determinants of additional time spent in childcare before and after the birth of a child, it is found that the marginal time costs are not the same across households of various sizes. Firstborn children cost significantly more in terms of additional mother's time than children of higher birth orders. In addition, the time costs of the second child are found to be significantly greater than those of the third child. However, these economies of scale in childcare are limited and do not extend beyond three children. The effect of birth spacing on the marginal time costs of children is also found to be significant.  相似文献
