Sexual behavior and drug consumption among young adults in a shantytown in Lima, Peru

<p>Abstract</p> <p>Background</p> <p>Risky sexual behaviors of young adults have received increasing attention during the last decades. However, few studies have focused on the sexual behavior of young adults in shantytowns of Latin America. Specifically, studies on the association between sexual behaviors and other risk factors for sexually transmitted infections (STI) and HIV/AIDS transmission, such as the consumption of illicit drugs or alcohol are scarce in this specific context.</p> <p>Methods</p> <p>The study participants were 393 men and 400 women between 18 and 30 years of age, from a shantytown in Lima, Peru. Data were obtained via survey: one section applied by a trained research assistant, and a self-reporting section. Logistic regression was used to estimate associations between use of any illicit drug, high-risk sexual behaviors and reported STI symptoms, adjusting for alcohol consumption level and various socio-demographic characteristics.</p> <p>Results</p> <p>Among men, age of sexual debut was lower, number of lifetime sexual partners was higher, and there were higher risk types of sexual partners, compared to women. Though consistent condom use with casual partners was low in both groups, reported condom use at last intercourse was higher among men than women. Also, a lifetime history of illicit drug consumption decreased the probability of condom use at last sexual intercourse by half. Among men, the use of illicit drugs doubled the probability of intercourse with a casual partner during the last year and tripled the probability of reported STI symptoms.</p> <p>Conclusion</p> <p>Drug consumption is associated with high-risk sexual behaviors and reported STI symptoms in a Lima shantytown after controlling for alcohol consumption level. Development of prevention programs for risky sexual behaviors, considering gender differences, is discussed.</p

Gender differences in sex-related alcohol expectancies in young adults from a peri-urban area in Lima, Peru Diferencias de género en las expectativas generadas por el consumo de alcohol relacionadas con el sexo en adultos jóvenes de la periferia urbana de Lima, Perú

OBJECTIVES: To estimate the effect of sex-related alcohol expectancies (SRAE) on hazardous drinking prevalence and examine gender differences in reporting SRAE. METHODS: Trained research assistants administered part of a questionnaire to 393 men and 400 women between 18 and 30 years old from a peri-urban shantytown in Lima, Peru. The remaining questions were self-administered. Two measuring instruments-one testing for hazardous drinking and one for SRAE-were used. Multivariate data analysis was performed using logistic regression. RESULTS: Based on odds ratios adjusted for socio-demographic variables (age, marital status, education, and employment status) (n = 793), men with one or two SRAE and men with three or more SRAE were 2.3 (95% confidence interval (CI) = 1.4-3.8; p = 0.001) and 3.9 (95% CI = 2.1-7.3; p OBJETIVOS: Estimar el efecto de las expectativas generadas por el consumo de alcohol relacionadas con el sexo (SRAE) sobre la prevalencia del consumo peligroso y analizar las diferencias en la información sobre las SRAE según el género. MÉTODOS: Asistentes entrenados aplicaron parte de un cuestionario a 393 hombres y 400 mujeres de 18 a 30 años de edad residentes en un barrio marginal periurbano de Lima, Perú. Los participantes respondieron las preguntas restantes de forma individual. Se emplearon dos instrumentos de evaluación: uno sobre el consumo peligroso y otro sobre las SRAE. Se realizó un análisis multifactorial de los datos mediante regresión logística. RESULTADOS: Según las razones de posibilidades (odds ratios) ajustadas por algunas variables sociodemográficas (edad, estado marital, educación y situación laboral) (n = 793), los hombres con una o dos SRAE y los que tenían tres SRAE o más presentaron 2,3 (intervalo de confianza de 95% [IC95%]: 1,4 a 3,8; P = 0,001) y 3,9 (IC95%: 2,1 a 7,3; P < 0,001) veces más probabilidades, respectivamente, de ser bebedores peligrosos que los hombres sin SRAE. Los hombres informaron SRAE en una proporción significativamente mayor que las mujeres. CONCLUSIONES: En un barrio periférico pobre de Lima, las SRAE se asociaron significativamente con el consumo peligroso de bebidas alcohólicas en hombres, pero no en mujeres, y se observaron diferencias en la información sobre las SRAE según el género

Reporting of SRAE was significantly higher in men versus women. CONCLUSION: In a shantytown in Lima, SRAE is associated with hazardous drinking among men, but not among women, and reporting of SRAE differs by gender
