Intimate partner violence (IPV) is a serious global public health issue. At least one in three women worldwide has been beaten, coerced into sex, or otherwise abused during her lifetime. According to the Bureau of Justice Statistics, more than three women in the United States die every day from physical abuse suffered at the hands of an intimate partner. IPV is defined as violence that occurs within the private sphere, generally between individuals who are related through intimacy, blood, or law. When perpetrated against women, IPV is generally understood to include physical, sexual, and psychological abuse by intimate male partners.

Introduction: Men who have sex with men (MSM) have higher smoking rates than the general population in the United States, but less is known about smoking among MSM in developing countries. Thus, we examined the prevalence and correlates of smoking among MSM in China., Methods: We conducted a cross-sectional study of 404 MSM in Shanghai, China (half of whom were male sex workers), recruited through respondent-driven sampling. Assessments included sociodemographics; tobacco, alcohol, and drug use; the Center for Epidemiological Studies Depression Scale (CES-D); the Social Provisions Scale (SPS); and the Lesbian, Gay, and Bisexual Identity Scale (LGBIS)., Results: Smoking prevalence was 65.9% in this sample. Recent smoking (i.e., in the past 3 months) was significantly associated with lower education, greater alcohol use, and higher LGBIS scores, after controlling for important sociodemographics. Among smokers, smoking ≥10 cigarettes per day (CPD), in comparison with <10 CPD, was related to older age and lower LGBIS scores and marginally related to heavy alcohol use. Although bivariate analyses indicated a relationship of CES-D and SPS scores to recent smoking, these factors did not contribute to the regression models., Conclusions: Smoking rates among MSM in China are higher than MSM in the United States and men in China. Less comfort with one's sexual orientation was related to smoking, particularly light smoking. Heavier alcohol consumption, lower education, and older age were also associated with smoking. Future research should confirm these findings and examine mediators and moderators of these relationships in order to inform cessation interventions and tobacco control policy.

Purpose: We assessed the prevalence, incidence, and correlates of substance use among Asian American individuals transitioning from adolescence to young adulthood., Methods: Data were obtained from the National Longitudinal Study of Adolescent Health, Wave II (1996) and Wave III (2001). Information on substance use was abstracted from a nationally representative sample of 1108 Asian Americans and Pacific Islanders (AAPIs) from both Waves. Weighted prevalence, incidence, and patterns of smoking, binge drinking, marijuana use, and other drug use were analyzed by sexual orientation and gender. Multiple logistic regression analyses were conducted to investigate the unique contribution of being a sexual minority in relation to four types of substance use by gender., Results: A link between sexual orientation and substance use behaviors among AAPIs did not emerge until young adulthood. Significant increases in the incidence and prevalence of all four types of substance use (tobacco, binge drinking, marijuana, and other drugs) were found among sexual minority AAPIs. Specifically being an AAPI sexual minority young woman, compared with being a heterosexual young woman, a heterosexual young man, or a sexual minority young man, was significantly associated with substance use after controlling for demographic characteristics, problem behaviors, and substance use during adolescence. Also the highest prevalence of substance use was found among AAPI sexual minority women., Conclusions: These findings add greater urgency to addressing the role of sexual orientation in designing substance abuse programs.

Objectives: This report presents the national estimates of maternal depressive symptomatology prevalence and its socio-demographic correlates among major racial/ethnic-nativity groups in the United States. We also examined the relationship of mental health-seeking patterns by race/ethnicity and nativity., Methods: Using the Early Childhood Longitudinal Survey-Birth Cohort Nine-month data, we present the distribution of Center for Epidemiological Study-Depression (CES-D) score by new mothers' nativity and race/ethnicity. The mental health-seeking pattern study was limited to mothers with moderate to severe symptoms. Weighted prevalence and 95% confidence intervals for depression score categories were presented by race/ethnic groups and nativity. Multi-variable logistic regression was used to obtain the adjusted odds ratios of help-seeking patterns by race/ethnicity and nativity in mothers with moderate to severe symptoms., Results: Compared to foreign-born mothers, mothers born in the U.S. were more likely to have moderate to severe depressive symptoms in every racial/ethnic group except for Asian/Pacific Islanders. These US-born mothers were also more likely to be teenagers, lack a partner at home, and live in rural areas. Among Asians, Filipina mothers had the highest rate of severe depressive symptoms (9.6%), similar to those of US-born black mothers (10.2%). Racial/ethnic minorities and foreign-born mothers were less likely to consult doctors (OR: 2.2 to 2.5) or think they needed consultation (OR: 1.9 to 2.2) for their emotional problems compare to non-Hispanic White mothers., Conclusion: Our research suggests that previous "global estimates" on Asian American mental health underestimated sub-ethnic group differences. More efforts are needed to overcome the barriers in mental health services access and utilizations, especially in minority and foreign-born populations.

In this study of 248 predominantly heterosexual Asian American college students, we found some HIV risks: lifetime prevalence of unprotected sex (37%), alcohol before sex (23.8%), and drug use before sex (6.0%). The prevalence of lifetime anal sex is only 9%, but 90.48% of those who have ever had anal sex did so without a condom. The Sexual Risk Indices, measured with a 13 item risky sexual behavior checklist, are positively associated with age. Most students have inadequate HIV knowledge. Acculturation is positively associated with the 30-day HIV Sexual Risk Index and HIV Knowledge Score. Preference for speaking English at home and for American entertainment is associated with higher likelihood of sexual activities, safe or unsafe. Lifetime Sexual Risk Index is also associated with 30-day and lifetime alcohol use. Lifetime drug use is associated with 30-day and lifetime Sexual Risk Indices. Alcohol before use in the lifetime also reliably predicts unprotected sex in the lifetime.

Neoparamoeba pemaquidensis is a parasomal amoeboid protozoan identified as the agent of amoebic gill disease (AGD) in Atlantic salmon Salmo salar reared in sea-pens in Tasmania, Australia, and coho salmon Oncorhynchus kisutch farmed on the west coast of the USA. Outbreaks of AGD caused by immunologically cross-reactive paramoebae have also been reported in sea-farmed salmonids in several other countries. Complete 18S rDNA sequences were determined for respective paramoebae isolated from infected gills of salmon from Tasmania and Ireland, and N. pemaquidensis isolates from the USA and UK, including representative free-living isolates. Alignments over 2110 bp revealed 98.1 to 99.0% sequence similarities among isolates, confirming that paramoebae implicated in AGD in geographically distant countries were homologous and belonged to the same species, N. pemaquidensis. The results supported previous findings that N. pemaquidensis exists as a widely distributed, amphizoic marine protozoan. Partial 18S rDNA sequences were obtained for the ultrastructurally similar species, N. aestuarina, and for the morphologically similar but non-parasomal amoeba Pseudoparamoeba pagei. N. aestuarina had 95.3 to 95.7% sequence similarities with N. pemaquidensis strains, which distinguished 2 closely related but separate species. Neoparamoeba spp. were not analogous to P. pagei or to other marine Gymnamoebia. We designed 4 oligonucleotide primers based on elucidated 18S rDNA sequences and applied them to single-step and nested 2-step PCR protocols developed to identify N. pemaquidensis to the exclusion of apparently closely related and non-related protistan taxa. Nested PCR was able to detect the AGD parasite from non-purified, culture-enriched net microfouling samples from Atlantic salmon sea-pens in Tasmania, and confirmed that N. pemaquidensis was also responsible for AGD in chinook salmon O. tshawytscha in New Zealand. Our sequence and PCR analyses have now shown that AGD affecting 3 different salmonid species farmed in 4 countries are associated with N. pemaquidensis. A species-specific diagnostic PCR provides for the first time, a highly specific detection and identification assay for N. pemaquidensis that will facilitate future ecological and epidemiological studies of AGD.
