Men who have sex with men (MSM) remain the most severely affected risk group in the US HIV/AIDS epidemic. One-third to two-thirds of HIV transmissions among MSM are estimated to come from primary sex partners. Couples HIV testing and counseling (CHTC), in which two individuals receive pre-test counseling, HIV testing and post-test prevention planning(More)
BACKGROUND Gay, bisexual, and other men who have sex with men account for a disproportionate burden of HIV incidence in the United States, with one-third to two-thirds of these new HIV infections occurring within main partnerships. Early initiation and adherence to highly active antiretroviral treatment is a key factor in treating and preventing the(More)
Current understanding of biologic processes indicates that women's nutritional status before and during early pregnancy may play an important role in determining early developmental processes and ensuring successful pregnancy outcomes. We conducted a systematic review of the evidence for the impact of maternal nutrition before and during early pregnancy(More)
Supplementation with multiple micronutrients (MM) during pregnancy may result in improved pregnancy and infant outcomes. We conducted meta-analyses of randomised controlled trials that evaluated the effects of prenatal supplementation with MM (defined as containing at least five micronutrients and typically included iron or iron and folic acid). The(More)
Evidence from observational studies and randomised trials has suggested a potential association between intake of n-3 long-chain polyunsaturated fatty acids (LCPUFA) during pregnancy and certain pregnancy and birth outcomes. Marine foods (e.g. fatty sea fish, algae) and select freshwater fish contain pre-formed n-3 LCPUFA, which serve as precursors for(More)
Micronutrient deficiencies are common and often co-occur in many developing countries. Several studies have examined the benefits of providing multiple micronutrient (MMN) interventions during pregnancy and childhood, but the implications for programs remain unclear. The key objective of this review is to summarize what is known about the efficacy of MMN(More)
BACKGROUND The Centers for Disease Control and Prevention recommends that sexually active men who have sex with men (MSM) in the United States test for human immunodeficiency virus (HIV) at least three times per year, but actual testing frequency is much less frequent. Though mHealth is a popular vehicle for delivering HIV interventions, there are currently(More)
INTRODUCTION Same-sex serodiscordant male dyads represent a high-priority risk group, with approximately one to two thirds of new HIV infections among men who have sex with men attributable to main partnerships. Early initiation and adherence to highly active antiretroviral therapy is a key factor in HIV prevention and treatment; however, adherence to(More)
Men who have sex with men account for a disproportionate burden of HIV incidence in the USA. Although much research has examined the drivers of sexual risk-taking, the emotional contexts in which men make sexual decisions has received little attention. In this three-phase, 10-week longitudinal qualitative study involving 25 gay and bisexual men, we used(More)
In countries such as the USA, gay and bisexual men experience high rates of intimate partner violence. However, little is known about the factors that contribute to this form of violence. In this study, we examine gay and bisexual men's perceptions of sources of tension in same-sex male relationships and how these may contribute to intimate partner(More)
