RESUMO
Abstract: aim: to determine the prevalence and risk factors for HPV infection in normal oral mucosa of Chilean dentistry students. Materials and methods: A cross-sectional study was performed. The study group was comprised of 103 individuals between 18 and 33 years old. A self-administered survey of cancer family history, sexual habits, smoking and alcohol drinking was applied. Oral mucosal samples were taken using a sterile swab. Subsequently, all samples were analyzed by polymerase chain reaction technique (PCR). Results: Results were negative for HPV detection in all analyses. Of the study population, 58 percent had a family history of cancer, 40.9 percent had had more than 3 sexual partners, 76.3 percent had sexual intercourse before the age of 19, 66.3 percent had engaged in oral sex, 69.9 percent drank alcohol and 20.6 percent were smokers. Conclusions: The group studied is exposed to various risk factors for HPV infection, so it is necessary to educate about the relationship between them and the spread of the virus. Despite the presence of risk factors, the detected prevalence of HPV was 0 percent.
Resumen: se realizó un estudio de corte transversal. El grupo de estudio fue constituido por 103 individuos entre 18 y 33 años. Se aplicó una encuesta autoadministrada sobre antecedentes familiares de cáncer, hábitos sexuales y consumo de tabaco y alcohol. Se tomaron muestras de la mucosa oral utilizando un hisopo estéril. Posteriormente, todas las muestras fueron analizadas mediante técnica de reacción en cadena de la polimerasa (PCR). Resultados: Los resultados fueron negativos para la detección de VPH en todos los análisis. De la población estudiada el 58 por ciento presentó antecedentes familiares de cáncer, el 40,9 por ciento ha tenido más de 3 parejas sexuales, el 76,3 por ciento se inició sexualmente antes de los 19 años, el 66,3 por ciento ha practicado sexo oral, un 69,9 por ciento es bebedor de alcohol y el 20,6 por ciento es fumador. Conclusiones: El grupo analizado está expuesto a diversos factores de riesgo de infección VPH, por lo que es necesario educar acerca de la relación entre estos y el contagio con el virus. A pesar de la presencia de factores de riesgo en los encuestados, la prevalencia detectada de VPH fue de 0 por ciento.

OBJECTIVES: To evaluate the prevalence of dyslipidemia and comorbidity in adults older than 20 years attending to the family medicine clinic number 20 of Instituto Mexicano del Seguro Social and to compare it with the prevalence in Mexico. METHOD: the study was conducted in 2005 by using a cross-sectional design; dyslipidemia was ascertained by measuring total cholesterol and triglycerides. Additional variables were: gender, age, health status, and diagnosis of diabetes, hypertension, overweight, and obesity. A standardization procedure and a dry run were carried out before beginning the data collection phase. RESULTS: The study included 165 participants, 35.2 % had hypercholesterolemia and 63.6 % had hypertriglyceridemia. According to the variables, 20.0% of people aged 40 to 59 years of age; 57.1% of women; 40.9% of overweight, 40.9% of obese and 49.5% of healthy patients had hypertriglyceridemia; while 68.9% of women; 44.8% of patients with hypertension, and 51.7 % of overweight patients had hypercholesterolemia. CONCLUSION: The prevalence of hypertriglyceridemia and hypercholesterolemia were significantly different from previous reports (hypercholesterolemia z< or =2.83; p < 0.001; hypertriglyceridemia z = 7.83; p < 00.1), being higher in women and increasing with aging.
