RESUMEN
HIV/AIDS is a major worldwide health concern. The present study was conducted to determine knowledge and attitudes towards AIDS among high school students in Pakdasht. Six hundred and fifty five students [404 females and 251 males] from 10 pre-university centers participated in the survey. An anonymous self-administered questionnaire was used to measured knowledge [40 [true, false, do not] items], attitudes [16 items, 5-point Likert-type scale], and seven query [age, sex, educational field, sources of information, adequacy of information, need to more education and suitable ages]. Attitude toward HIV/AIDS was positive. General knowledge of 45.5% students was good [true responses to more than 75% of items], 45.2% was moderate [true responses to 50- 74% of items] and only 9.3% had weak knowledge [true responses to less than 25% of items]; however, results revealed low level of knowledge to oral sex, heterosexually contact, and the protective role of condom. TV was identified as the most frequent source of information, while 90% indicated the need for receiving HIV prevention education in the future. These defects may lead to further exposure to and contamination with HIV/AIDS. Thus, we recommend further surveys in this regard
