Resum
After having carried out a review of the literature on the relationship between sex education and sexual and contraceptive behavior, the National Research Council (1987) recently concluded that the existing evaluation of the effects of sex education on sexual and contraceptive practices is helpful but not sufficient. One possible explanation for the different results obtained are the diverse sociodemographic characteristics of the sample or samples of teenagers under consideration. Another aspect that can account for the differences found in the literature focuses on the areas covered in the course. In Mexico no studies have been carried out which deal with the relationship between sex education and sexual and contraceptive behavior. A study was carried out with 392 female teenagers between 16 and 17 years old of lower and middle lower socioeconomic level. Results show that the mere fact of attending a sex education course did not affect the initiation or continuation of sexual activity, contraceptive behavior or even the perception of accessibility to contraception. Providing information on sexuality, relationship with the partner and where to obtain contraceptives does not have an effect on sexual activity. Receiving information on pregnancy prevention and on where to obtain contraceptives was found to be related to contraceptive use. Although less dramatic, information about the relationship with the partner and on sexuality also produced increases in contraceptive use. (Extraído del documento)
