Background and Aim: Presently not sufficient attention is paid to adolescent health promotion in many countries, because of the widespread belief that adolescents are generally healthy. The purpose of this study was to evaluate predictors of adolescent girls' quality of life using path analysis based on Pender's health promotion model.

Materials and Methods: The Pender's health promotion model served as the framework of this cross-sectional study, which included a total of 500 adolescent girls (grades 9-11) selected by stratified random sampling from 20 high schools for girls in 4 districts of Kashan province, Iran. Inclusion criteria were being in grades 9-11 and a written informed consent (from teachers, parents and the girls themselves). Data were collected through interviewing the girls, the interviewers being trained persons, using several standard questionnaires (for perceived self-efficacy, perceived affect, perceived barriers, perceived social support health promoting lifestyle, and health-related quality of life). Data analysis was done using SPSS18 and LISREL 8.8, the statistical test being path analysis.

Results: All constructs of the health promotion model and health promoting lifestyle were significantly related to adolescent girls' quality of life. Perceived self-efficacy (β=0.70, p<0/01) and perceived affect (β=0.21, p<0/01) had the highest correlation with the quality of life. The model and the health-promoting lifestyle as a mediator accounted for 73% and 39% of variance in adolescent girls' quality of life, respectively.

Conclusion: The findings of this study indicate that the health promotion model can be used to explain and predict the quality of life of adolescent girls. Thus, the Pender's health promotion model is recommended to health planners for promoting the quality of life in this population.

Background and Aim: The aim of this study was to assess the adherence to anti-retroviral prophylaxis after occupational and non-occupational exposure to human immunodeficiency virus (HIV) in patients consulting the Voluntary Counseling and Testing Center (VCT) of Imam Khomeini Hospital, Tehran during the period 2008 to 2009.

Materials and Methods: In this prospective study, patients were selected, the required information about them was recorded, and adherence to anti-retroviral drugs (including Ziduvudin, Lamivudin and Efavirens) was determined based on self-report by the patients. Eighty-nine exposed patients were followed monthly for 4 months, and in the case of low-adherence (less than 95%) they were asked for the reason(s) for noncompliance.

Results: Of the 89 patients, 55 were men (61.8%) and 34 (38/2%) were women with a mean age of 30.16± 8.39 years 47 participants (52.8%) were single and 42 (47.1%) married 27 subjects (30.3%) were physicians, 35 (39.3%) nurses and 27 (30.3%) had occupations outside the healthcare system. From among the 36 subjects (40.5%) who stopped the treatment, 24 (27.0%) stopped it correctly (that is, when the serological test proved to be negative), while 12 (13.4%) did not stop it on a sound basis. Fifty-three subjects (59.6%) completed the prophylaxis. Adherence was found to be significantly associated with age and marital status (p<0.05).

Conclusion: The main reason for stopping the prophylaxis (a negative serological test result of the resource patient) was more pronounced than previous studies, which indicates the higher availability of the resource patient.
