Background.?Saliva collection is an easy, non-invasive method to measure hormones.Methods.?Two studies were performed. In the first, a convenience sample of 1454 males who had submitted saliva for salivary testosterone measurements were studied. In the second study, we intensively studied symptoms and measurements of total testosterone, free testosterone symptoms and measurements of total testosterone, free testosterone and bioavailable testosterone in relationship to salivary testosterone in 127 men. A secondary endpoint was to examine the relationship of salivary testosterone to hypogonadal symptoms in the ADAM and AMS questionnaires.Results.?In the first study, we have shown that salivary testosterone, measured in 1454 males aged 20 to 89 years, declines by 47% over the lifespan. In the second study, salivary testosterone was strongly correlated with bioavailable testosterone (p < 0.000001) calculated free testosterone (p < 0.00001) and total testosterone (p < 0.002). Salivary testosterone was significantly related to hypogonadal symptoms on the St. Louis University ADAM questionnaire and the Aging Male Survey.Conclusions.?These studies support the use of salivary testosterone as an acceptable assay for screening for hypogonadism. Salivary testosterone is not a better assay than other measures to diagnose hypogonadism. 相似文献

AbstractObjective: College and university administrators have expressed concern that adoption of tobacco-free policies may reduce applications and enrollment. This study examines adoption and implementation of 100% tobacco-free campus policies by institutions of higher education on applications and enrollment. Participants: North Carolina private colleges and universities and public community colleges. Analysis was conducted in 2011. Methods: Student enrollment and application data were analyzed by campus type to determine (a) if there was a difference in student applications and enrollment before and after policy implementation, and (b) if there was a difference in student applications and enrollment for campuses with versus without a policy. Results: No significant differences were found in student enrollment or applications when comparing years prior to and following policy implementation or when comparing with institutions without 100% tobacco-free campus policies. Conclusions: The authors found no evidence that 100% tobacco-free policy adoption had an impact on student enrollment or applications. 相似文献

Sexual minority adolescents (SMA) report more suicide risk behaviors than heterosexual adolescents. Polyvictimization (co‐occurrence of multiple types of victimization) may be an important, underresearched correlate of this disparity. With the 2017 national Youth Risk Behavior Survey (N = 13,179), national estimates of polyvictimization and suicide risk were assessed among high school students by sexual minority status (SM vs. heterosexual), and multivariate relationships between sexual minority status, polyvictimization, and suicide risk were tested. Additionally, risk profiles of those who experienced polyvictimization (2 + types of victimization; n = 1,932) were compared across sexual minority status. Results confirm that SMA are more likely to experience polyvictimization than heterosexual adolescents (31.8% v. 12.9%, respectively); however, also indicate that polyvictimization does not fully explain elevated suicide risk among SMA. 相似文献

Interactions with mothers and fathers form a critical foundation for youths’ later peer relationships. This study focused on the associations of maternal and paternal sensitivity in third grade with friendship outcomes in sixth grade. Because interactions with parents provide the earliest opportunities for children to learn prosocial behaviors such as cooperation, and cooperation is theoretically conceptualized as a foundation of friendship, cooperation may play a role in the link between parenting and children’s later social relationships. Using the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development sample (N = 955; 51% female; 83% White), and a multimethod, multireporter longitudinal design, children’s cooperation was tested as a mediating mechanism that linked parental sensitivity to early adolescent friendship. Results indicated that most indirect paths from both mothers and fathers’ sensitivity to observed friendship interactions and perceived friendship quality, via cooperation, were significant. Findings provide a more concrete understanding of how parental sensitivity translates to better friendships. 相似文献

As service populations have changed, the social work profession in the UK and the US has attempted to respond to the needs of diverse cultures, which often include issues of religion and spirituality. This can be problematic, however, due to the extrication of religious and spiritual concerns from the public social services that resulted from the process of secularization. Members of the British Association of Social Workers (BASW) and the National Association of Social Workers (NASW) in the US were sampled to explore the attitudes and perceptions of social workers regarding the placement of religion and spirituality in practice and education. In general, US social workers in this sample were more accepting of religion and spirituality than their UK counterparts, even among those respondents who expressed non‐religious world views (e.g. atheism). A majority of the respondents in the UK (76%) and the US (73%) indicated that their training programs lacked content on religion and spirituality. In the UK, 57% of the respondents believed that social workers should increase their knowledge on spirituality, compared with 90% of the US respondents. The lower level of acceptance of religion and spirituality among UK social workers may be related to higher levels of secularism in UK society. 相似文献

The current quandary with the design of existing long-term care settings results from focus on structures (“institutions”) instead of on a system of supports and services that transcends physical and traditional boundaries across settings, including nursing homes, assisted living residences, and the home. Supported by analyses of the commonalities, socio-historical and political contexts, core values, and fallacies of social and medical models in existing and emerging long-term care options, a holistic model is proposed based on new core values that facilitate community and family integration and that asserts dignity and personhood as universal attributes in an array of settings. 相似文献

This article analyzes off‐farm work among subsistence‐level farmers in the Santarém region of the Brazilian Amazon. We build on the literature on rural livelihoods in the Global South by exploring how the opportunity to work off the farm is embedded in social relationships. We additionally differentiate our analysis by type of off‐farm work, and examine how other characteristics such as human capital, the available labor supply, and access to infrastructure vary by work outcome. In general, the factors that contribute to more secure, relatively higher‐paying work differ from those important in understanding patterns of lower‐paying, daily wage work. We find that on‐farm social capital, measured as the presence of a co‐resident on the property who works off the farm, increases an individual's probability of working off the farm, but has a stronger effect for lower‐wage work. We also find that the farm owner's relationship to households on the farm property plays a significant role in predicting patterns of off‐farm work. These findings suggest that social capital plays an important role in providing access to employment and therefore to cash income, but that farm‐level social capital does not necessarily provide pathways to stable or high‐paying jobs outside agriculture. 相似文献
