Knowledge, behavior, and attitudes of adolescent university students towards HIV infection and AIDS

The aim of this study was to evaluate the knowledge, behavior, and attitudes of students entering the University of Buenos Aires (UBA) towards HIV/AIDS, as well as to determine the differences between genders and between groups with different behavior in terms of HIV/AIDS risk behavior, through the conduct of an ad hoc semi-structured questionnaire. This questionnaire was completed anonymously by 12,000 university students going in for compulsory medical check-up at the Health and Social Welfare Office of the UBA. Two thousand cases were selected by simple randomized sampling and statistically analyzed. Results revealed that: (1) 87.2

of the population under study was between 18 and 27 years old; (2) the students’ knowledge of the subject was acceptable; (3) the percentage of respondents who reported having sexual intercourse with more than one person decreased as the number of sexual partners in a year increased. Less than 1.5

explicitly stated being homosexual or bisexual; (4) 53.9

of the men and 46.7

of the women claimed they always used condoms; (5) analysis of the perception of their own risk showed that 75

considered they were not at risk; (6) between 95.8

were in favor of developing educational-preventive activities and 64.2

thought compulsory AIDS screening for job applicants or candidates for educational courses was discrimination. Conclusions: (a) Information available to admission course students is sufficient. However, there are contradictions in their responses about their own behaviors; (b) Most of the respondents are in favor of the corresponding Faculties implementing educational and preventive measures. The students would regard the University’s intervention as a way of fulfilling its social role.

Effect of self-brushing with acidulated phosphate fluoride (pH 5.6) on dental caries in children

The aim of this work was to study the effect of a preventive program on the dental plaque and on the caries incidence in school children. The program comprised weekly supervised self brushing with acidulated phosphate fluoride (APF) gel (pH 5.6; concentration: 4520 ppm of ion F-). The program involved 240 children of 1st., 3rd and 5th grade of a primary school in the City of Buenos Aires (Argentina). The population was divided in 2 groups: A (experimental) and B (control). Ninety children from both groups (45 experimental and 45 control) were submitted to baseline clinical examination (DMFT and plaque index) and microbiological analysis (total streptococci, St mutans and St. mutans and St. mutans percentage). Group A was then submitted to a preventive program which included self brushing with APF gel (4520 ppm of ion F-). The 90-children sample was monitored after 1 and 2 years of program. Results were statistically processed and they revealed the following: a--DMFT was significantly greater in the control group than in the experimental group after 1 and 2 years of program; b--an 81.43

reduction in caries increment rate at the end of the 2-years program in the experimental group as compared to the control group; c--a rise in the number of colonies of total streptococci and of St. Mutans; d--a reduction in the

of St. mutans in the total streptococci flora in the plaque of children in the experimental group; e--the presence of St. mutans colonies featuring a rough surface; f--the effectiveness of the program in the modifying the profile of the diagnosed dental pathology.
