Adolescents and young adults (ages 13–24) in the USA are frequently exposed to violence in their community and home. While studies have examined the prevalence and impact of violence exposure among adolescents, there is a lack of data focusing specifically on adolescent men of color who have sex with men. Eight demonstration sites funded through a Special Projects of National Significance (SPNS) Initiative recruited 363 HIV-positive racial/ethnic minority young men who have sex with men (YMSM) for a longitudinal study between 2006 and 2009. Over two-thirds of participants (83.8%) had witnessed community violence, 55.1% in the prior three months. Witnessing violence committed with a deadly weapon was significantly associated with being African-American, having ever used drugs, and drinking alcohol in the prior two weeks. Fear of violence in the community was significantly associated with depressive symptomatology, having less than a high school degree, not possessing health insurance, and site of enrollment. Having been emotionally or physically abused by a parent or caretaker was significantly associated with depressive symptomatology, attempting suicide, site of enrollment, and increased age. Witnessing violence with a deadly weapon was significantly associated with alcohol and drug use but not with high-risk sexual behaviors. As this was one of the first studies on the prevalence and correlates of violence exposure among racial/ethnic minority YMSM living with HIV, the findings can be used to inform the development of culturally appropriate resilience-focused interventions to address the aftereffects of violence exposures and help develop social support systems outside of the family. 相似文献

Although most current studies have established the importance of school‐related parental involvement to adolescents' academic achievement, they are limited in that they do not address macrolevel community influences on such an association. This may be due in part to the lack of community‐level data or the use of inappropriate statistical strategies that cannot account for the influence of factors at the community level. To address this limitation, in this study, the authors examined the influence of community poverty on the association between school‐related parental involvement and adolescents' academic achievement. Using a large, nationally representative sample, results from a multilevel model suggested that, compared to adolescents living in more affluent communities, the positive effect of school‐related parental involvement on adolescents' academic achievement was significantly weaker for adolescents living in poor communities. Such findings suggested the importance of community poverty in influencing the effectiveness of school‐related parental involvement on adolescents' academic achievement. 相似文献

Background
In Sweden, antenatal and child health care are offered free of charge to all expectant and new parents. Professionals in antenatal and child health care play an important role in supporting parents. Previous research shows that same-sex mothers face heteronormative assumptions and insufficient support during their transition to parenthood.Objective
To explore professionals' experiences of supporting two-mother families in antenatal and child health care.Method
A qualitative method with focus group discussions was used. An interview guide was followed, and the discussions were held online. The data was analysed according to inductive content analysis.Settings and participants
The participants were midwives (n = 8) and nurses (n = 5) in antenatal and child health care from different parts of Sweden. Participants were recruited through the coordinating midwives and child health care nurses in the different regions.Findings
One main category was identified: Striving to be open-minded in supporting same-sex mothers. Health care professionals described meeting well-prepared mothers, with an equal commitment between each other, and mothers on guard against heteronormative views. Professionals provided support through empowerment by creating a safe environment and aiming at providing equal support to all parents or tailored support to same-sex mothers. Mothers described handling challenges, as a balancing act to acknowledge both mothers. Struggling with documents and communication and a lack of information were other challenges to be handled. Professionals reflected on their own professional competence and expressed that knowledge acquired through education, experience and personal interest all contributed to their competence.Conclusions
Forms and documentation need to be updated to be gender neutral to be including to a variety of family constelleations. Health care professionals need time to reflect on norms and challenges to better support both mothers in a two-mother family. 相似文献54.

Given that ecological models of development highlight the interacting influences of multiple environments, further research is needed that explores ethnic-racial socialization from multiple contexts. The current study explores how families, schools, neighborhoods, and the Internet jointly impact academic outcomes, critical consciousness, and psychological well-being in adolescents, both through socialization messages and experiences with racial discrimination. The research questions were: (a) What profiles of multiple contexts of socialization exist? and (b) How are the different profiles associated with academic outcomes, critical consciousness, and psychological well-being? The sample consisted of 1,084 U.S. adolescents aged 13–17 (M = 14.99, SD = 1.37; 49% girls) from four ethnic-racial groups: 25.6% Asian American, 26.3% Black/African American, 25.3% Latinx, and 22.9% White. The participants completed online surveys of socialization and discrimination from four contexts and three types of outcomes: academic outcomes, critical consciousness, and well-being. A latent profile analysis revealed three profiles: Average, High Discrimination, and Positive School. The Positive School class had the most positive academic outcomes and well-being. The High Discrimination class reported the highest critical consciousness. Their academic outcomes and well-being were similar to the Average group. The findings support complexity in perceptions of socialization from different contexts and the associations of socialization with youth outcomes. 相似文献

This paper answers the question as to which parental phenotypes are useful in prediction of the linkage phase of the progeny under conditions of linkage equilibrium. I demonstrate that (1) the parents with the same disease status or marker genotype carry no information about phase of the diheterozygous offspring; (2) the linkage phase can be inferred unambiguously only under recessive or dominant control of disease. In any other situations, only the probability of linkage phase is inferred. It has been shown that the relative difference between the probabilities of coupling phase and repulsion phase, ζ, which is regarded as a measure of accuracy of linkage phase prediction by parental phenotypes, is the same in all informative crosses and is dependent on the genetic model of the disease. Furthermore, ζ is the same for the di- and polyallelic marker genes. © 1996 Wiley-Liss, Inc. 相似文献

Association studies of genetic markers with disease play a critical role in the dissection of genetically complex traits because they are relatively easy to conduct and are useful for fine-scale mapping of genetic traits. The advantage of family-based controls has recently received much attention because spurious associations caused by population structure can be controlled for, and marker genotype information on diseased cases and their parents can be used to test the compound hypothesis of both linkage and linkage disequilibrium. However, debate still exists regarding the statistical methods of analysis. Herein are presented statistical methods to test for linkage (in the presence of linkage disequilibrium) between multiallelic genetic markers and disease when diseased subjects (cases) and their parents are sampled. Theoretical considerations for the development of general statistical tests are presented as well as asymptotic formulas to compute their power when planning a study. Furthermore, simulation results for nine specific statistics are used to contrast the power of these methods under different genetic mechanisms leading to disease (dominant vs. recessive, one vs. two high-risk alleles). These results demonstrate substantial gains in power for specific statistical tests designed to detect specified genetic mechanisms. However, without a priori knowledge of the likely genetic mechanism, it is desirable to rely on a fairly robust statistical method, robust so that power is not drastically lost when either dominant or recessive mechanisms are acting, and when either one or more than one marker alleles are associated with disease. Based on both theoretical and simulation results, a general score statistic, which generalizes the transmission/disequilibrium test, tends to offer sufficient power for a variety of genetic mechanisms, so that it is worth considering for broad use in studies which use genetic marker information from both diseased cases and their parents. © 1996 Wiley-Liss, Inc. 相似文献
