Evidence for a role of LPGAT1 in influencing BMI and percent body fat in Native Americans.

Objective: A genome-wide association study (GWAS) was recently completed in 1120 Pima Indians to identify loci that influence BMI. Among the top 100 signals were three variants that mapped within the lysophosphatidylglycerol acyltransferase 1 (LPGAT1) gene. LPGAT1 belongs to a large family of acyltransferases, which are involved in a variety of biological processes including pathways that regulate energy homeostasis and body weight.

The Use of Female Commercial Sex Workers' Services by Latino Day Laborers.

This article reports the characteristics of Latino day laborers who have sex with female commercial sex workers (CSWs). A sample of 450 day laborers in Los Angeles was utilized. Multivariate logistic regression was used to determine the association of independent variables with the likelihood of having sex with a CSW.

Sexual solicitation of Latino male day laborers by other men.

Objective: To examine the likelihood of Latino day laborers being solicited for sex by other men.

Material And Methods: 450 Latino day laborers were recruited in Los Angeles, California, from July to September 2005. Logistic regression analysis was used to determine which day laborers were more likely to be solicited and subsequently to have sex.

Stigma in the HIV/AIDS epidemic: a review of the literature and recommendations for the way forward.

Although stigma is considered a major barrier to effective responses to the HIV/AIDS epidemic, stigma reduction efforts are relegated to the bottom of AIDS programme priorities. The complexity of HIV/AIDS-related stigma is often cited as a primary reason for the limited response to this pervasive phenomenon. In this paper, we systematically review the scientific literature on HIV/AIDS-related stigma to document the current state of research, identify gaps in the available evidence and highlight promising strategies to address stigma.

Evaluation of a prevention intervention to reduce HIV Risk among Angolan soldiers.

We developed and evaluated a military-focused HIV prevention intervention to enhance HIV risk-reduction knowledge, motivation, and behaviors among Angolan soldiers. Twelve bases were randomly assigned to HIV prevention or control conditions, yielding 568 participants. HIV prevention participants received training in preventing HIV (4.

HIV/AIDS behavioral surveillance among Angolan military men.

To assess HIV-related risk behavior among military men in a post-conflict sub-Saharan African country with low HIV prevalence this study evaluated sexual risk taking and related behaviors among a stratified random sample of 1,710 military personnel in four regions of Angola. Over 90% were sexually active and 60% had two or more sexual partners within the past year. Condom use varied depending on partner type, from a low of 10% to a high of 54%.

Protecting our militaries: a systematic literature review of military human immunodeficiency virus/acquired immunodeficiency syndrome prevention programs worldwide.

Objectives: To systematically review published studies of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) prevention programs targeting the world's military populations.

Methods: We systematically searched eight electronic databases (publications from 1983 to February 2005) and hand-searched the bibliographies of HIV/AIDS prevention reviews to identify evaluative studies of HIV/AIDS prevention interventions for military personnel.

Results: Five hundred eighty-four abstracts were identified, of which eight met formal acceptance criteria.

Evidence-based recommendations for prevention of human immunodeficiency virus and sexually transmitted infections in the Angolan Armed Forces: challenges and opportunities at the end of 30 years of war.

Objective: The goal was the development of culturally sensitive, evidence-based recommendations for human immunodeficiency virus (HIV) prevention for Angolan soldiers.

Methods: Eight focus groups (N = 68) were conducted with Angolan soldiers in 2002. Qualitative data were analyzed for soldiers' HIV/sexually transmitted infections (STIs)-related knowledge and behaviors.

Perceived employment barriers and their relation to workforce-entry intent among people with HIV/AIDS.

As treatments have improved health and quality of life for people with HIV/AIDS, many have contemplated workforce reentry. Workforce reentry rarely occurs among people with illness-related disability. The authors mailed a survey that included workforce-entry-related concerns to 1,991 HIV/AIDS clients.

A prospective study of computer users: II. Postural risk factors for musculoskeletal symptoms and disorders.

Background: Despite widespread recommendations regarding posture during computer use, associations between specific postures and musculoskeletal health are not well characterized.

Methods: Six hundred and thirty-two newly hired computer users were followed prospectively to evaluate associations between posture and neck or shoulder (N/S) and hand or arm (H/A) musculoskeletal symptoms and musculoskeletal disorders. Participants' postures were measured at entry and they reported symptoms on weekly diaries.

A prospective study of computer users: I. Study design and incidence of musculoskeletal symptoms and disorders.

Background: A prospective study of computer users was performed to determine the occurrence of and evaluate risk factors for neck or shoulder (N/S) and hand or arm (H/A) musculoskeletal symptoms (MSS) and disorders (MSD).

Methods: Individuals (n = 632) newly hired into jobs requiring > or = 15 hr/week of computer use were followed for up to 3 years. At study entry, workstation dimensions and worker postures were measured and medical and psychosocial risk factors were assessed.
