Este artículo examina la prevalencia del VIH, los conocimientos respecto a su infección y, además, describe el uso del condón en mujeres que ejercen el comercio sexual en Santiago de Chile y que son atendidas en cinco centros especializados de enfermedades de transmisión sexual. Se aplicó una encuesta que indagaba sobre las características sociodemográficas, el conocimiento sobre el VIH/SIDA y el uso del condón a 626 mujeres. La prevalencia del VIH fue evaluada mediante un examen de ELISA. La prevalencia del VIH fue 0. El conocimiento del VIH fue bueno e, incluso, mejor que en población general, en algunos indicadores. El uso del condón con los clientes fue alto, aunque su uso regular con las parejas estables fue bajo. La prevalencia cero del VIH y el uso consistente de condones con los clientes confirma el impacto positivo que han tenido las estrategias de intervención implementadas para estos grupos, incrementando el conocimiento adecuado sobre el SIDA y el uso del condón con los clientes, contribuyendo a la disminución de la vulnerabilidad de estas mujeres hacia el.

This paper describes HIV seroprevalence, knowledge of HIV transmission, and condom use among female sex workers (FSW) attending five specialized sexually transmitted disease (STD) clinics in Santiago, Chile. A short questionnaire with socio-demographic, AIDS knowledge, and condom-use variables was administered to 626 FSW. HIV seroprevalence was estimated with a blood test sent to the Chilean Public Health Institute. ELISA was used to confirm HIV in suspected cases. HIV prevalence was 0%. FSW showed adequate overall knowledge of HIV, even better than reported for the Chilean general population on some items. Condom use with clients was high ("always" = 93.4%), although regular use with steady partners was low ("always" = 9.9%). The zero HIV seroprevalence and consistent condom use with clients confirms the positive impact of intervention strategies for FSW, increasing both correct knowledge of AIDS and condom use with clients and helping decrease these women's HIV/AIDS vulnerability.

A avaliação do estado nutricional antropométrico, através do índice de massa corporal (IMC), foi realizada a partir de inquérito domiciliar com amostra probabilística da população adulta de Niterói, Rio de Janeiro, Brasil. Nos domicílios selecionados, moradores com idade ³ 20 anos tiveram a massa corporal e a estatura medidas no próprio domicílio. As estimativas para a população mostraram baixa prevalência de baixo peso (IMC < 18,5kg/m²) enquanto 45,8% das mulheres e 49,6% dos homens tinham excesso de massa corporal (IMC ³ 25kg/m²). Houve tendência a um gradiente na prevalência de baixo peso dos setores censitários de menor para os de maior renda. A prevalência do excesso de massa corporal não apresentou tendência evidente em função da renda ou escolaridade nos homens, mas houve relação inversa com a escolaridade entre as mulheres. A prevalência de obesidade (IMC ³ 30kg/m²) variou de 5,6 a 19,3% entre os homens e de 9,6 a 21,3% entre as mulheres em função da faixa etária. Conclui-se que o excesso de massa corporal é o agravo nutricional mais prevalente na população de Niterói.

Resumo em Inglês:

A household survey was conducted to assess the nutritional status of the adult population in Niterói, Rio de Janeiro, Brazil. In the selected households, all adults (³ 20 years) had their body mass and stature measured. Body mass index (BMI) was used to determine the nutritional status according to the World Health Organization classification. The population estimates showed low prevalence of underweight (BMI < 18.5kg/m²), while 45.8% of women and 49.6% of men were overweight/obese (BMI ³ 25kg/m²). Obesity prevalence varied from 5.6% to 19.3% in men and from 9.6% to 21.3% in women, according to age. The prevalence of overweight/obesity was not associated with income (in either men and women) or schooling (in men), but there was an inverse relationship between schooling and overweight/obesity in women. The prevalence of underweight decreased with increasing mean income in the census enumeration area. The authors conclude that overweight/obesity is the most prevalent nutritional disorder in both men and women in Niterói. This pattern resembles recent results for the adult population in Southeast Brazil as a whole, where Niterói is located.
