- Helicobacter pylori infection and body mass index in adolescentsPublication . Pereira, Carlos; Veiga, Nélio; Amaral, Odete; Baptista, Marco; Nelas, Paula; Chaves, Cláudia; Ferreira, Manuela; Coelho, InêsIntroduction: Recent studies have revealed an association between overweight and obesity and the risk of Helicobacter pylori (HP) infection. The aim of this study was to quantify the association between overweight and obesity and the risk of developing HP infection in a sample of portuguese adolescents. Methods: A sample of 447 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 socio-demographic aspects, risk behaviours and daily habits was answered by adolescents.The adolescents were screened for HP infection using the 13C-urea breath test that consists in the exhalation of carbon dioxide in samples before and after swallowing urea labeled with non-radioactive carbon-13. Obesity was evaluated by the body mass index (BMI) calculated by the ratio of weight and height (Kg/m2), according to the Cole et al. tables. Prevalence was expressed in proportions and compared by the chi-square test. Crude odds ratio (OR) with 95% confidence intervals (CI) were used. Results: The prevalence of overweight and obesity was 13.0% and 1.6%, respectively. The prevalence of HP infection was 35.9%. Overweight and obesity was not associated with gender (male, OR=0.9 95%CI=0.5-1.6), age (>15 yrs, OR=1.3 95%CI=0.7-2.3), father´s professional situation (unemployed, OR=1.8 95%CI=0.8-4.1) smoking habits (yes, OR=0.7 95%CI=0.4-1.4), alcohol consumption (yes, OR=1.0 95%CI=0.5-2.0) and soft drink consumption (yes, OR=1.2 95%CI=0.4-3.4). However, overweight and obesity was associated with parents`educational level (< 9th grade, OR=2.1 95%CI=1.2-3.8), residential area (rural, OR=1.6 95%CI=1.1-2.8) and coffee consumption (yes, OR=1.7 95%CI=1.2-2.9). After adjustment by non-conditional logistic regression for gender, age, parents´educational level, father´s professional situation, residence area and coffee consumption the HP infection is not associated with overweight and obesity (OR=1.4 95%CI=0.8-3.2). Conclusions: Overweight and obesity in adolescents is associated with socio-demographic variables and addictive habits, but not with HP infection.
- Obesity and quality of life in adolescentsPublication . Veiga, Nélio; Amaral, Odete; Pereira, Carlos; Ferreira, Sonya; Tavares, Isabel; Chaves, CláudiaBackground: Obesity may interfere with social, psychological and physical activities. The aim of this study was to analyse the association between obesity and health related quality of life (HRQOL) in adolescents. Methods: In a cross-sectional study, we evaluated 7563 students (54.4% females) aged 12-18 years (14.8±1.8) from Viseu, Portugal. Obesity was evaluated by the body mass index (BMI) calculated by ratio of self-reported weight and square of the height (Kg/m2), according to the Cole et al tables, and classified into three groups: “normal weight” (< 25.0), “overweight” (25.0 to 29.9), and “obese” (> or = 30.0). The HRQOL was assessed by SF36 (ranging from 0 to 100) which includes eight dimensions. Proportions were compared by chi-square test and continuous variables by the Kruskal-Wallis test. Results: The total scores of SF36 are significantly lower in overweight and obese adolescents (80.3±13.5 vs. 79.6±13.8 vs. 75.0±14.3, p<0.01, in the male sex and 74.1±13.5 vs. 73.3±14.2 vs. 69.3±16.0, p<0.01, in the female sex). For all dimensions that compose the scale we can verify lower scores among overweight and obese adolescents. The overweight adolescents referred more feelings of marginality relatively to their colleagues/friends (19.6% vs. 13.7%, p<0.01 in the male sex and 24.6% vs. 16.1%, p<0.01 in the female sex) and more feelings of inferiority relatively to their colleagues/friends (38.8% vs. 11.1%, p<0.01 in the male sex and 29.5% vs. 20.8%, p<0.01 in the female sex). Conclusions: Overweight and obesity were associated with impaired HRQOL, with deterioration of physical and emotional well-being. The impairment of HRQOL found in obese adolescents can be associated with restrictions, even though subtle, in daily life.
- 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.
