This is the first study to empirically identify distinct acculturative adjustment patterns of new international students over their first 3 semesters in the United States. The sample consisted of 507 Chinese international students studying in the United States. Using psychological distress as an indicator of acculturative adjustment, measured over 4 time points (prearrival, first semester, second semester, and third semester), 4 distinct groups of student adjustment trajectories emerged: (a) a group exhibiting high levels of psychological distress across each time point (consistently distressed; 10%), (b) a group with decreasing psychological distress scores from Time 1 to Time 2 (relieved; 14%), (c), those with a sharp peak in psychological distress at Time 2 and Time 3 (culture-shocked; 11%), and (d) a group with relatively consistent low psychological distress scores (well-adjusted; 65%). Moreover, significant predictors of a better acculturative adjustment pattern included having higher self-esteem, positive problem-solving appraisal, and lower maladaptive perfectionism prior to the acculturation process. In addition, during the first semester of studying in the United States, having a balanced array of social support and using acceptance, reframing, and striving as coping strategies were associated with a better cross-cultural transition. Practical implications and future directions were also discussed.

Healthcare professionals should work with gatekeepers to create a supportive local environment for condom use in sex work establishments. Gatekeepers need to clearly articulate their support for condom use to the FSWs. Training and skill acquisition regarding correct use of condoms among FSWs will be necessary.

This study examines the association between depressive symptoms and condom use with clients among 278 female sex workers (FSW) in Guangxi, China. About 62% of these FSW had a high level of depressive symptoms (CES-D total score ≥ 16). Multiple logistic regression analyses indicated that FSW with high level of depressive symptoms were less likely to use condoms consistently (aOR = 0.50, 95% CI: 0.28-0.89) or use condoms properly (aOR = 0.44, 95% CI: 0.20-0.99). The findings suggested that HIV prevention programs targeted at FSW should take into consideration the level of depression they experience.

The robust and consistent expression of the CD13 cell surface marker on very early as well as differentiated myeloid hematopoietic cells has prompted numerous investigations seeking to define roles for CD13 in myeloid cells. To address the function of myeloid CD13 directly, we created a CD13 null mouse and assessed the responses of purified primary macrophages or DCs from WT and CD13 null animals in cell assays and inflammatory disease models, where CD13 has been implicated previously. We find that mice lacking CD13 develop normally with normal hematopoietic profiles except for an increase in thymic but not peripheral T cell numbers. Moreover, in in vitro assays, CD13 appears to be largely dispensable for the aspects of phagocytosis, proliferation, and antigen presentation that we tested, although we observed a slight decrease in actin-independent erythrocyte uptake. However, in agreement with our published studies, we show that lack of monocytic CD13 completely ablates anti-CD13-dependent monocyte adhesion to WT endothelial cells. In vivo assessment of four inflammatory disease models showed that lack of CD13 has little effect on disease onset or progression. Nominal alterations in gene expression levels between CD13 WT and null macrophages argue against compensatory mechanisms. Therefore, although CD13 is highly expressed on myeloid cells and is a reliable marker of the myeloid lineage of normal and leukemic cells, it is not a critical regulator of hematopoietic development, hemostasis, or myeloid cell function.

This study evaluates the efficacy of cultural adaptation of a voluntary counseling and testing (VCT) intervention, in increasing condom use and decreasing rates of sexually transmitted diseases (STDs) among a group of female sex workers (FSWs) in Guangxi, China. This intervention is modeled after the "state-of-the-science" VCT program that was developed and evaluated by the Center for Disease Control and Prevention's Project RESPECT. Four hundred FSWs were assigned to either an intervention group receiving the VCT intervention or a control group receiving standard of care STD testing and treatment. Data were collected at baseline and 6 months postintervention. Outcome measures included HIV/STD related knowledge and perceptions, condom use, and history of STDs. Five common STDs were screened and tested through clinical examination and laboratory testing to serve as biomarkers. After controlling for potential confounders and baseline differences, the VCT intervention group was significantly higher than the control group in HIV/STD related knowledge (p < .0001) and consistent condom use with clients (odds ration [OR] = 2.23; 95% confidence interval [CI] = 1.26-3.96) at 6 months follow-up. In addition, the intervention group had a significantly lower infection rate of STDs than the control group at follow-up (OR = 0.44; 95% CI = 0.24-0.80). This quasi-experimental trial provides evidence that the brief VCT intervention, through appropriate cultural adaptation, can be efficacious in increasing condom use and reducing STD infection rate among FSWs in China.Data from both industrialized (Kamb, Fishbein, Douglas, Rhodes, & Rogers, 1998;RotheramBorus, Cabtwell, & Newman, 2000) and developing countries (Coates, et al., 2000;Merson, Dayton, & O'Reilly, 2000;Painter, 2001) suggest that culturally appropriate voluntary counseling and testing (VCT) programs are effective in facilitating a change toward safer sex behavior and in reducing HIV/STD (sexually transmitted disease) transmission. In a multisite international trial in three developing countries (Kenya, Tanzania, and Trinidad), Coates and colleagues (2000) suggested that pre and posttest HIV counseling is effective as a prevention strategy for both individuals and couples. Among the 3,000 individuals enrolled in the study, the rate of unprotected sex with nonprimary partners decreased more significantly among those who received VCT than those who received only basic health information. Among the 586 NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript couples enrolled in the study, reduction of unprotected sex with enrolled partners was significantly greater among VCT groups than those who received health information alone.There has been considerable debate regarding effective ways to deliver HIV/STD counseling for promoting condom use and preventing incidental STD (Kamb et al., 1998;Rotheram-Borus et al., 2000). For the past decades, the standard for counseling has been the delivery of factbased didactic messages aimed at increasing cl...

Since the 1980s, informal or clandestine sex work in the service or entertainment industry has spread from municipalities to small towns in most areas of China. Despite recognition of the important role of female sex workers in HIV and STD epidemics in China, limited data are available regarding their individual characteristics and the social and environmental context of their work. Furthermore, most existing studies on commercial sex in China have been conducted in large cities or tourist attractions. Using data from 454 female sex workers in a rural Chinese county, the current study was designed to explore the individual profiles of commercial sex workers and to examine whether the profile and sexual risk behaviour differ by where the female sex workers came from and where they work. The sample in the current study was different from previous studies in a number of key individual characteristics. However, similarly to previous studies, the subjects in the current study were driven into commercial sex by poverty or limited employment opportunities, lived a stressful life, were subject to sexual harassment and related violence, and engaged in a number of health-compromising behaviours including behaviours that put them at risk of HIV/STD infection and depression. The findings of the current study underscore the urgent need for effective HIV/STD prevention, intervention and mental health promotion programs among female sex workers in China. The data in the current study suggest a strong association of individual profile with the economic conditions of work sites and residence status (in-province residency vs. out-of-province residency), which suggests that such efforts must take the social and cultural contextual factors of working environment (and sexual risks) into consideration.

This study attempted to determine the association of self-efficacy with condom-use practice and to explore reasons of not using condoms among female sex workers (FSWs) with steady partners in China. Data from 309 establishment-based FSWs with steady partners in one Chinese county were collected through a cross-sectional study. Consistent condom use with steady partners was lower than with clients in entertainment establishments. Condom-use self-efficacy was positively associated with condom-use communication and condom-use frequency with clients but not with steady partners. It was positively associated with condom-use intention and skill with clients and steady partners. However, it was not associated with appropriate use of condoms. Significant differences of reasons about not using condom were also observed between the two partner types. The results may represent an important challenge to STD and HIV intervention programs aimed at achieving consistent condom use in FSWs. Health workers should focus on psychosocial factors affecting inconsistent condom use among FSWs with steady partners in China. In addition, intervention programs that can promote FSWs' self-efficacy through condom-use skill training will still be necessary.
