The purpose of this work is to do a research on the level of awareness about sexually transmitted diseases (STD) of adolescence and the factors effecting it. Method A number of adolescent at the ages of 14-17 (n=527) were asked to complete a survey questioning their level of knowledge of STDs and their sociological and demographical issues.Data were entered into the SPSS 15.0 program and evaluated. A value of p<0.05 was assumed for statistical significance. Findings 78.9% of the adolescent responded positively to the question of whether or not they are aware of the fact that diseases could be transmitted via sexual intercourse. 48.6% of the adolescent responded negatively to whether or not they knew "how the diseases are transmitted", 59.4% responded negatively to whether or not they know "how to protect themselves from those diseases", and 67.2% responded negatively to whether or not they know "the symptoms of STDs". The count of the right answers were in increase in correlation with the education and economic level of the parents (p<0.05). The results showed that 49.3% of them learned information about STDs at school and from medical institutions. 9.3% of them stated that they had intercourse in the last one-year period and 8.0% of them utilized a method of protection. Result Awareness level of adults about STDs is inadequate. For that, schools and medical institutions, where they are inclined most to get education, should organize mass education events for them about these matters. RELATIONSHIP BETWEEN OBESITY AND 8-HYDROXY 2-DEOXY GUANOSINE AS AN OXIDATIVE MARKER IN Anthropology, National Research Centre, Cairo, EgyptBackground and Aim This study was conducted to assess the relationship between obesity markers (Body mass index "BMI", fat percentage) and DNA oxidative marker 8-hydroxyl guanosine (OHG), as a predictor for future clinical problems in obese adolescents of Giza. Methods The study was conducted on 103 adolescents aged 13-18 years (22 boys, 81 girls). BMI was calculated as body weight (kg) divided by height (m 2 ) squared and obesity was defined as BMI of 95 percentile. Fat percentage was determined by using Biological impedance technique. Oxidative stress markers as 8-hydroxyl guanosine, superoxide and gluthione were measured. The adolescents were divided according to BMI into two groups. Group I with BMI > 95 percentile and less than 97 percentile (obese) and Group ∩ with BMI > 97 percentile (severely obese). Results Significant differences were detected between the two groups of the study as regard obesity markers (BMI, fat %) and oxidative stress markers (lipid oxidation, superoxide dismutase enzyme activity, glutathione peroxidase enzyme activity, 8-hydroxyl guanosine) (p<0.0005). Significant positive correlations were detected between obesity markers and oxidative stress markers among severely obese adolescent (group II). Obesity is highly associated with states of oxidative stress in adolescents, with a positive relation with 8-hydroxy-guanosine and obesity markers and other oxidative marke...
