OBJECTIVE: To analyze differences in health behavior among students studying health related subjects in public universities, between the beginning and end of their courses. METHODS:The study sample comprised 735 students in health sciences at the public universities in Pernambuco state (Northeastern Brazil) in 2006. The data were collected by means of the National College Health Risk Behavior Survey that had been validated previously for use among university students. Descriptive and inferential statistical techniques were used. The chi-square test or Fisher's exact test was used to analyze associations. Results were considered to be signifi cant for p≤0.05. RESULTS:The majority (69.5%) of students were female. Fewer students were found to be living with their parents or a guardian by the end of the course. However there were no signifi cant differences for violent behavior, related to weight and physical activity, nor for most behavior relating to traffi c safety and food intake. The consumption of alcohol (68.8% vs. 83.3%), tobacco (40.7% vs. 52.5%) and inhalants (10.2% vs. 21.9%) and sexual practices (62.5% vs. 85.0%) were more frequent by the end of the course, with statistically signifi cant differences. CONCLUSIONS:In general, health behaviors did not differ signifi cantly between students at the beginning and end of graduate courses in health sciences.

A high percentage of children presented with dental anxiety and a history of dental pain.

The rate of success of restorations using the ART approach was significantly lower for class II.

The prevalence of dental anxiety was high, although children attending private schools and those who had visited the dentist before had a lower prevalence of dental anxiety.

A high degree of satisfaction was observed with children and their parents in the four types of restoration after placement. However, if it could be chosen in advance, children prefer the PMCs and parents a tooth-coloured material.

OBJECTIVE To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students.METHODS This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals.RESULTS Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19–5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use.CONCLUSIONS The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion.
