Hortensia de Los Angeles Amaro: Influence Statistics

Female sex workers (FSWs) have been documented to have high rates of sexually transmitted diseases and HIV in many parts of the world. However, little work has been done to characterize the prevalence of these infections along the U.S.-Mexican border, where sexual tourism and culturally sanctioned sex work among nationals is widespread. The objective of this study was to compare differences in background characteristics, HIV risk behaviors, drug use, and sexually transmitted ...

OBJECTIVES: We examined the efficacy of a brief behavioral intervention to promote condom use among female sex workers in Tijuana and Ciudad Juarez, Mexico.

METHODS: We randomized 924 female sex workers 18 years or older without known HIV infection living in Tijuana and Ciudad Juarez who had recently had unprotected sex with clients to a 30-minute behavioral intervention or a didactic control condition. At baseline and 6 months, women underwent interviews and testing for HIV, syphilis, ...

Objective: To assess whether adolescents with a history of sexual abuse were more likely than those with no such history to engage in sexual risk behaviors. Methods: Data for this study were obtained through the 1997 Massachusetts Youth Risk Behavior Survey, a self-report questionnaire administered to a representative sample of 9th through 12th graders (N = 4014) to assess a variety of adolescent risk behaviors. Only sexually experienced adolescents (n = 1610; female = 779, male = 831) ...

BACKGROUND: HIV prevalence is increasing among female sex workers (FSWs) in Tijuana and Ciudad Juarez, 2 Mexican cities on the US border. Quasilegal prostitution in both cities attracts large numbers of sex tourists. We compared FSWs with and without US clients in both cities.

METHODS: FSWs aged > or =18 years reporting unprotected sex with > or =1 client within the last 2 months, who were not knowingly HIV-infected, were enrolled in a behavioral intervention study. At baseline, ...

BACKGROUND: Brief alcoholism screening questionnaires have not been adequately studied in the rapidly growing Latino population living in the United States.

OBJECTIVE: To assess (1) the prevalence of alcoholism and (2) the performance of 2 alcohol screening instruments in Latinos.

SUBJECTS AND METHODS: We performed a cross-sectional interview study in an urban teaching hospital-based primary care practice. Consecutive self-identified Latino subjects provided informed consent. All ...

Although therapeutic treatments exist for substance use disorder (SUD), about half of individuals who enter treatment leave early and relapse to substance use. Early dropout from residential treatment places individuals at risk of relapse, and women in SUD residential treatment represent a vulnerable population. Evidence gaps persist for the use of mindfulness-based interventions (MBIs) among racially and ethnically diverse women with SUDs, especially regarding the efficacy of MBIs ...

In order to assess the relationship between lifetime and during pregnancy experience of violence and low birth weight (LBW) and preterm birth outcomes, we designed a prospective cohort study in which the birth outcomes of women who experienced violence before their pregnancy or who experienced violence during pregnancy were compared to women who reported no lifetime experience of violence. We found that the risk of having a low birth weight or preterm baby was higher for women who did ...

PURPOSE: To examine correlates of early initiation into sex work in two Mexico-U.S. border cities.

METHODS: Female sex workers (FSWs) >/=18 years without known HIV infection living in Tijuana and Ciudad Juarez who had recent unprotected sex with clients underwent baseline interviews. Correlates of initiation into sex work before age 18 were identified with logistic regression.

RESULTS: Of 920 FSWs interviewed in Tijuana (N=474) and Ciudad Juarez (N=446), 9.8% (N=90) were early initiators ...

To investigate the effects on infants of the use of marijuana and cocaine during pregnancy and to compare the importance of urine assays with that of interviews in ascertaining drug use, we prospectively studied 1226 mothers, recruited from a general prenatal clinic, and their infants. On the basis of either interviews or urine assays conducted prenatally or post partum, 27 percent of the subjects had used marijuana during pregnancy and 18 percent had used cocaine. When only positive ...

Emerging adulthood has been described as a difficult stage in life and may be particularly stressful for Hispanic emerging adults who are disproportionately exposed to adversity and chronic sociocultural stressors. To better prevent and treat depressive disorders among Hispanic emerging adults, more research is needed to identify and understand modifiable determinants that can help this population enhance their capacity to offset and recover from adversity and sociocultural stressors. As ...

OBJECTIVE: To examine associations between migration and sexually transmitted infection (STI) prevalence among Mexican female sex workers (FSW).

METHODS: FSW aged 18 years and older in Tijuana, Baja California (BC) underwent interviews and testing for HIV, syphilis, gonorrhoea and chlamydia. Multivariate logistic regressions identified correlates of STI.

RESULTS: Of 471 FSW, 79% were migrants to BC. Among migrant FSW, prevalence of HIV, syphilis, gonorrhoea, chlamydia and any STI was ...

BACKGROUND: We examined human immunodeficiency virus (HIV) prevalence and correlates among female sex workers (FSWs) in Tijuana and Ciudad Juarez, 2 large cities on the Mexico-US border.

METHODS: FSWs aged > or =18 years underwent interviews and testing for HIV, syphilis, gonorrhea, and chlamydia. Logistic regression identified factors associated with HIV infection.

RESULTS: In 924 FSWs, the prevalence of HIV, gonorrhea, chlamydia, and syphilis titers > or =1:8 was 6%, 6.4%, 13%, and ...

We examined relationships between client-perpetrated emotional, physical, and sexual abuse, injection drug use, and HIV-serostatus among 924 female sex workers (FSWs) in Tijuana and Ciudad Juarez, two large Mexico-US border cities. We hypothesized that FSWs' injection drug use would mediate the relationship between client-perpetrated abuse and HIV-seropositivity. The prevalence of client-perpetrated emotional, physical, and sexual abuse in the past 6 months was 26, 18, and 10% ...

OBJECTIVES: We examined the relationship between discrimination and substance use disorders among a diverse sample of Latinos. We also investigated whether the relationship between discrimination and substance use disorders varied by gender, nativity, and ethnicity.

METHODS: Our analyses focused on 6294 Latinos who participated in the National Epidemiologic Survey on Alcohol and Related Conditions from 2004 to 2005. We used multinomial logistic regression to examine the association ...

Women's ability to negotiate safer sexual practices, particularly condom use, is a vital component of HIV/STD prevention strategies. Gender-based power imbalances may constrain women's negotiation ability, yet few empirical studies have tested the hypothesis that sexual relationship power constitutes a key factor in condom use negotiation. In this investigation, a new measure - the Sexual Relationship Power Scale (SRPS) - was applied. Data were collected from 388, mostly Latina, women at ...
