- Association of sleep disorders with overweight and obesity in a Portuguese community sample of adolescentsPublication . Pereira, Carlos; Amaral, Odete; Veiga, NélioBackground: Several studies have shown that overweight and obesity is associated with sleep disorders. Aim: The aim of this study was to determine the association between sleep disorders and overweight and obesity in Portuguese adolescents. Methods: In a cross-sectional approach we assessed 7136 students from twenty-six schools of the district of Viseu, Portugal. The overweight and obesity was evaluated by the body mass index (BMI). Insomnia was defined based on the DSM-IV criteria, as the presence of one or more symptoms:difficulty initiating sleep;difficulty maintaining sleep;early morning awakening and difficulty getting back to sleep;non-restorative sleep. Results: The prevalence of overweight and obesity among the adolescents is 32.9% (higher in male gender 37.9% vs. 28.6%,p<0.001) and 4.7% (higher in male gender 6.7% vs. 2.9%,p<0.001), respectively. The prevalence of symptoms of insomnia is 21.4%. Insomnia is present in 22.4% of adolescents with overweight and 25.5% with obesity. Insomnia is associated with overweight (OR=1.32 95%CI1.1-1.86) and obesity (OR=1.11 95%CI1.0-1.30). Among the female gender insomnia was associated with overweight (OR=1.2 95%CI1.0-1.43) and obesity (OR=1.64 95%CI1.2-2.78) and also among the male gender (overweight,OR=1.31 95%CI1.1-1.71 and obesity,OR=1.62 95%CI1.01-2.61). Conclusions: The association between sleep disorders and obesity has not been fully clarified, however, several studies predict that the association is bidirectional.
- Oral health behaviours in a sample of portuguese adolescents: an educational issuePublication . Veiga, Nélio; Pereira, Carlos; Ferreira, Paula; Correia, Ilidio J.Introduction: Oral health education is an important issue that should be given to children and adolescents, allowing the acquisition of correct oral health behaviors. The objective of this study was to determine the prevalence of oral health behaviors among a sample of portuguese adolescents and verify the association with socio-demographic factors, in order to analyze the main needs related with oral health education to improve oral health status among adolescents. Methods: A cross-sectional study was designed with a sample of 447 adolescents aged 12 to 19 years old, attending a public school in Sátão, Portugal. A self-administered questionnaire was applied questioning about socio-demographic factors and oral health behaviors to each adolescent in the classroom. Prevalence was expressed in proportions and crude odds ratio (OR) with 95% confidence intervals (CI) were used to measure the strength of association between oral health behaviors and socio-demographic factors. Results: The prevalence of tooth brushing (twice-a-day or more) was 90.6%. Five point eight percent of adolescents reported daily flossing, more frequent among female gender (female, OR = 2.03, 95% CI = (1.35 to 3.05)) and adolescents older than 15 years (>15 years, OR = 1.90, 95% CI = (1.24 to 2.92)). Sixty-seven percent had at least one dental appointment in the previous twelve months. The prevalence of dental appointments was associated with the father’s professional situation (unemployed, OR = 0.33, 95% CI = (0.17 to 0.65)) and crowding index (>1, OR = 0.4, 95% CI = (0.16 to 0.98)). Thirty-two point nine percent of adolescents referred having at least one episode of dental pain during their lives. Conclusion: Considering the results of the present study that show the need of improvement of some aspects related with oral health among adolescents, oral health community programs and primary preventive strategies, such as improvement of oral health education in schools should be considered in order to reduce the risk level of oral diseases and develop better oral health behaviors.
- Prevalence of fissure sealants in a portuguese sample of adolescentsPublication . Veiga, Nélio; Pereira, Carlos; Baptista, Marco; Chaves, Cláudia; Nelas, Paula; Amaral, Odete; Ferreira, Manuela; Ferreira, Paula; Correia, Ilidio; Coelho, InêsBACKGROUND The use of fissure sealants is an effective intervention for the primary prevention of pit and fissure caries in children and adolescents. The objective of this study was to determine the prevalence of fissure sealants in a portuguese sample of adolescents. PARTICIPANTS AND METHODS A sample of 293 adolescents aged 12 to 18 years old, attending a public school in Sátão, Portugal, was enrolled in this cross-sectional study. A self-administered questionnaire with questions about oral health behaviours, knowledge and socio-economic status was answered by the adolescents in the classroom. Clinical examination of oral health status and assessment of fissure sealants was accomplished by a trained and calibrated research team. The presence of fissure sealants in each tooth was assessed as total or partial. Prevalence was expressed in proportions and compared by the chi-square test. Crude odds ratio (OR) with 95% confidence intervals (CI) were used to measure the strength of association between the presence of fissure sealants and the independent variables. RESULTS We verified that 26.3% (95%CI= 25.0-34.0) of adolescents refer knowing the definition of a fissure sealant, while only 5.9% (95%CI= 4.3-7.0) refer having fissure sealants applied on their teeth. The prevalence of fissure sealants was 52.7% (95%CI= 35.0-46.0), higher among the female gender (59.6% vs 46.2%, p=0.03). The presence of fissure sealants was associated with a lower prevalence of dental caries (dental caries, OR=0.32, 95%CI=0.18-0.59) and residence area (rural, OR=2.24, 95%CI=1.25-4.02). Among the adolescents with at least one tooth with fissure sealants, 21.7% (95%CI=13.9-30.0) presented total fissure sealants in sealed teeth, while 78.3% (95%CI= 70.1-86.1) presented one or more teeth with partial fissure sealant. CONCLUSIONS We found a low prevalence of fissure sealants and a high prevalence of partial and infiltrated sealants among adolescents. A low prevalence of adolescents know the definition and indications of a fissure sealant. It is necessary the establishment of a more targeted preventive program with better and more effective oral health education.
- Prevalence of h. pylori infection in a portuguese sample of adolescents.Publication . Pereira, Carlos; Veiga, Nélio; Baptista, Marco; Chaves, Cláudia; Nelas, Paula; Amaral, Odete; Ferreira, Manuela; Caldo, José; Teixeira, SantiagoBACKGROUND There are some gaps in knowledge of the prevalence and determinants of Helicobacter pylori (H. pylori) infection acquired during childhood. The aim of this study was to estimate the prevalence of H. pylori in a portuguese sample of adolescents using 13C-urea breath test (13C-UBT). PARTICIPANTS AND METHODS A sample of 293 adolescents aged 12 to 18 years old, attending a public school in Sátão, Portugal, was enrolled in this cross-sectional study. A self-administered questionnaire was answered by the adolescents in classroom in order to assess socio-demographic and symptoms. The adolescents were screened for H. pylori infection using the 13C-UBT test and needed to fast for at least one hour before the test. The 13C-UBT test consisted in the exhalation of carbon dioxide in samples before and after swallowing urea labeled with non-radioactive carbon-13. Prevalence was expressed in proportions and compared by the chi-square test. Crude odds ratio (OR) with 95% confidence intervals (CI) were used to measure the strength of association between H. pylori infection and the independent variables. RESULTS The prevalence of H. pylori infection was 40.4% (95%CI= 35.0-46.0). The H. pylori infection was associated with gender (female, OR=1.52, 95%CI=1.0-2.46), age (>15 years, OR=1.78, 95%CI=1.1-3.28) parents´ educational level (>9th grade, OR=1.53, 95%CI=1.0-2.50), alcohol consumption (yes, OR=1.45, 95%CI=1.0-2.36), crowding index (≥1, OR=3.49, 95%CI=1.2-13.83), soft drink consumption (yes, OR=0.48, 95%CI=0.22-0.98). CONCLUSIONS Nearly half of the adolescents were positive for H. pylori infection, suggesting that gastric pathology continues to be considered an important public health problem among the population, including among adolescents.
