    Background: The Chilean Ministry of Health has been using standards for nutritional evaluation and weight gain recommendations during pregnancy in the last 25 years. In the meantime new standards have been developed. Aim: To study the combined influence of preconception maternal nutritional status and gestational weight gain, using new standards to classify those parameters, on perinatal outcomes. Material and Methods: A cohort of 11,465 healthy pregnant women was prospectively followed until term. Their pre-gestational nutritional status was classified using the body mass index cut-offs in use in the United States (USA). Their gestational weight gain was classified using categories proposed in a Danish study. Perinatal outcomes included were risky birth weight, i.e. < 3000 g and >= 4000 g, and cesarean delivery Relative risks for those perinatal outcomes were calculated for all combined categories of pre-gestational nutritional status and gestational weight gain. Results: Relative risks of almost all gestational weight gain results were statistically significant for women having a normal pre-gestational nutritional status meanwhile all of them were not significant for underweight women. Overweight and obese women had similar relative risks values as normal women. However, many of them were not significant, especially in obese women. Conclusions: There is an independent and combined influence of preconception nutritional status and gestational weight gain on perinatal outcomes, when using standards to classify those parameters developed in the USA and Denmark, respectively (Rev Med Chile 2011; 139: 710-716).

    Knowdlege and preventive behaviors related to cervical cancer and human papiloma virus in a group of Chilean adolescents
    (SOC CHILENA INFECTOLOGIA, 2012) Teresa Urrutia, M.; Concha, Ximena; Riquelme, Giselle; Padilla, Oslando
    Knowdlege and preventive behaviors related to cervical cancer and human papiloma virus in a group of Chilean adolescents Introduction: The human papilloma virus (HPV) is a common sexually transmitted infection in young people and recognized as the most important risk factor for cervical cancer (CC). Aim: To describe the degree of knowledge that a group of Chilean teenagers have of HPV infection, CC, and its relationship with preventive behavior. Methods: This is an analytical study, with a random sample of 226 adolescents from three public schools of the Metropolitan Region in Santiago. Results: A fifth of the interviewed students did not know there was a HPV vaccine. Multiple sexual partners was indicated as a risk factor of CC by 70.8% and of HPV infection by 78.3% of them; while 60.3% identified inheritance as a risk factor. HPV transmission through unprotected sexual relations was identified by 68.2% of the sample. Of sexually active adolescents, condom use during sexual relations was reported by 31.1%. The adolescents who use condoms significantly have more knowledge regarding the number of sexual partners and age of first sexual intercourse as a risk factor for CC. Conclusion: adolescents know about HPV transmission, however, the preventing conducts are not related to this information.
