- 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.
- Automedicação na comunidade : um problema de saúde públicaPublication . Amaral, Odete; Veiga, Nélio; Nelas, Paula; Coutinho, Emília; Chaves, ClaudiaIntrodução: A automedicação é um importante problema de saúde pública e constitui um desafio em diversos países europeus, designadamente em Portugal. Os objetivos deste estudo foram estimar a prevalência de automedicação numa amostra de adultos portugueses da Região Centro e Norte de Portugal e identificar fatores sociodemográficos e de saúde associados à automedicação. Participantes e métodos: Estudo transversal analítico. A amostra ficou constituída 197 indivíduos da comunidade, região centro e norte de Portugal, com uma média de idades de 38,26±14,20 anos e maioritariamente do género feminino (65,0%). Os dados foram recolhidos através da aplicação de um questionário, composto por questões de caracterização sociodemográfica, de contexto de saúde e questões referentes à automedicação. Resultados: No total da amostra a prevalência de automedicação ao longo da vida foi de 74,1% e nos últimos 6 meses foi de 59,9%. A automedicação ao longo da vida associou-se significativamente com a área de residência urbana (p=0,018). A automedicação nos últimos 6 meses relacionou-se positivamente com a idade ≤25 anos (OR=3,69; IC95% 1,04-12,14) e negativamente com a área de residência (rural OR=0,36; IC95% 0,15-0,84). Conclusões: Observámos elevadas prevalências de automedicação ao longo da vida e nos últimos 6 meses na comunidade norte e centro de Portugal. A automedicação associou-se com variáveis sociodemográficas e de saúde. Os resultados do presente estudo criam evidência para o planeamento de intervenções no âmbito do controlo da automedicação na comunidade.
- Comportamentos de saúde oral em adolescentes portuguesesPublication . Pereira, Carlos; Veiga, Nélio; Amaral, Odete; Pereira, JoanaIntrodução: A frequência da escovagem, a utilização do fio dentário e a consulta regular ao médico dentista são importantes determinantes de saúde oral. O objetivo deste estudo foi caracterizar os comportamentos de saúde oral numa amostra de adolescentes portugueses, mais especificamente a prevalência de escovagem, a utilização de fio dentário e as consultas regulares ao médico dentista, e estabelecer a associação destes comportamentos com aspetos sociodemográficos. Participantes e métodos: Realizámos um estudo transversal onde avaliámos os alunos de 26 escolas públicas do terceiro ciclo e secundário do distrito de Viseu. Em cada escola avaliámos todos os adolescentes do 7.◦ ao 12.◦ ano de escolaridade. A recolha de dados foi efetuada através de um questionário autoaplicado e respondido pelos adolescentes em sala de aula, contendo questões referentes a comportamentos de saúde oral e estatuto socioeconómico. Dos 8768 distribuídos, recolhemos 7644 (87,2%). Foram excluídos da análise os questionários sem informação para o sexo e para a idade, bem como os que correspondiam a idades inferiores a 12 ou superiores a 18 anos. Ficámos com uma amostra final de 7563 adolescentes (4117 do sexo feminino). Resultados: A prevalência de escovagem (2 ou mais vezes por dia) é de 23,5%, mais frequente no sexo feminino (25,5 vs. 21,2%, p < 0,01). A frequência da escovagem (2 vezes ou mais por dia) encontra-se associada às habilitações literárias dos pais (< 4 anos = 18,2%, 4-12 anos = 23,2% e > 12 anos = 44,2%, p < 0,01) e à área de residência (urbano = 36,9%, rural = 16,7%, p<0,01). A utilização diária do fio dentário é referida por 4,4% dos adolescentes, mais frequente no sexo feminino (4,6 vs. 4,1%, p < 0,05). 37,1% dos adolescentes referem nunca terem utilizado o fio dentário, 40,5% referem utilizá-lo às vezes e 18,1% desconhecem o fio dentário. 86,7% dos adolescentes referem ter consultado um médico dentista, uma ou mais vezes durante a vida e 55,0% referem que o fizeram nos últimos 12 meses. As razões mais frequentes para a ida à consulta nos últimos meses foram: consulta de rotina (49,8%), odontalgias (27,8%) e tratamentos dentários (21,6%).
- Dental caries and oral health behaviours in a portuguese sample of adolescentsPublication . Pereira, Carlos; Veiga, Nélio; Chaves, Cláudia; Nelas, Paula; Amaral, Odete; Coelho, Inês; Correia, Ilídio; Ferreira, Paula; Ferreira, Eduardo; Morais, Helena; Ferreira, ManuelaBackground The frequency of toothbrushing, use of dental floss and regular dental appointments are important behaviours to prevent oral diseases. The objective of this study was to determine the mean of decayed/missing/filled in permanent teeth (DMFT index) and assess the oral health behaviours in a 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 and socio-economic status was answered by adolescents in the classroom. Clinical examination of oral health status was carried out according to the World Health Organization criteria to determine the prevalence of dental caries and the DMFT index. Results The prevalence of toothbrushing (twice-a-day or more) was 78.2%, more frequent among the female gender (82.9% vs. 72.3%, p=0.02). Four point one percent of adolescents reported daily flossing, more frequent among female gender (48.4% vs. 37.3%, p=0.04). Sixty-two point five percent had a dental appointment once or more times in the previous twelve months and the most frequent reasons referred were: 74.3% for a dental check-up and 26.2% when having a toothache. The DMFT index was 3.26 and the prevalence of dental caries 40.1% associated with gender (male=33.3% vs female=45.5%, p=0.03), parents´ level of education (<4 yrs=27.3%, 4-12 yrs=44.7% and >12 yrs=22.2%, p=0.02) and fear of the dentist (no=37.8% vs yes=54.3%, p=0.05). Conclusions We found a moderate DMFT index and prevalence of dental caries. One forth of adolescents don´t make a annual dental check-up appointment and visit a dentist only when they have toothache. Oral health community programs and primary preventive strategies should be considered in order to reduce a higher level of oral diseases and improve oral health behaviours.
- Dental caries risk assessment in a portuguese sample of 6-year-old schoolchildrenPublication . Gonçalves, Joaquim; Veiga, Nélio; Ribeiro, Cláudia; Pereira, Carlos; Amaral, OdeteIntroduction: The National Program for the Promotion of Oral Health defines a set of goals, in terms of oral health, recognizing the importance of assessing the risk of dental caries. Objectives: Assess the individual risk of dental caries and associated oral health behaviors in a sample of sex-year-old children. Methods: A cross-sectional observational epidemiological study was carried out in a sample of 221 six-year-old children of the Group of Schools Diogo Cão, Vila Real. A intra-oral observation was performed and a self-administered questionnaire about the children oral health behaviors was applied to the parents. To determine the association between the risk of dental caries and oral health behaviors the Chi-square test, with a significance level of 5% was applied. Results: It was found that 61.1% of the children had a high risk of dental caries. The decayed, missing and filled index for deciduous teeth (dmft index) was 1.93 and 52% of the children were caries free. Statistical significant associations was found between the risk of dental caries and the level of education completed by fathers/mothers of children (p<0.001), consumption of cariogenic foods (p<0.001) and poor oral hygiene (p<0.001). Only 14.9% of children brushed their teeth at school after lunch and only 48.4% learned to brush their teeth at school. Conclusion: It seems important that schools develop more projects and practical activities of oral health, with special emphasis on the daily toothbrushing at school. Progress in terms of oral health, has been very little. Thus, if there isn’t a turn around, we will hardly reach the appointed value prescribed by the World Health Organization for the year 2020 in Europe, which is 80% of children free of caries at 6 years of age.
- Determinants of quality-of-life among a portuguese sample of adolescentsPublication . Amaral, Odete; Pereira, Carlos; Veiga, Nélio; Chaves, Cláudia; Baptista, Marco; Nelas, Paula; Ferreira, Manuela; Coelho, InêsBackground: Adolescents’ health has become an increasingly important issue and the perception of their health related quality-of-life (HRQoL) are influenced by socio-demographic factors and lifestyle habits. Objectives: The aim of this study was to analyze the determinants of HRQoL in a Portuguese sample of adolescents. Methods: A sample of 309 adolescents (66.9% female gender) aged 11 to 19 years old, attending a public school in Sátão, Portugal, was enrolled in this cross-sectional study. A self-administered questionnaire was used to assess social and demographic variables that included the 12-Item Short Form of Medical Outcomes Study (SF12) to assess HRQoL grouped in physical and mental dimensions (lower scores, better quality-of-life). We used the qui-square test to compare proportions and the Kruskal Wallis test to compare continuous variables. Results: The total scores of HRQoL were associated with depressive symptoms (yes=30.80±2.60 vs. no=33.42±2.97, p<0.01). The total scores of HRQoL were not associated with gender (female=33.58±2.81 vs. 33.39±3.26, p=0.62), neither were the mental dimensions (female=131.35±13.37 vs. 130.42±15.53, p=0.61) and physical dimensions (female=183.89±18.72 vs. 182.59±21.74, p=0.61). Total scores of HRQoL were also not associated with age (11-13yrs= 34.00±3.41; 14-16yrs= 33.59±3.22; 17-20yrs= 33.25±2.60, p=0.27), residence area (rural=33.66±3.01 vs. urban=33.24±2.74, p=0.26); alcohol consumption (yes=33.03±2.68 vs. no=33.76±3.13, p=0.06), coffee consumption (yes=33.15±3.11 vs. no=33.77±2.88, p=0.10); smoking habits (yes=33.01±2.56 vs. no=33.72±3.12, p=0.08); sports practice (yes=33.53±3.17 vs. 33.60±2.60, p=0.84) and insomnia (yes=32.44±2.59 vs. 33.08±2.38, p=0.24). Conclusions: The impairment of quality-of-life in adolescents was not associated with socio-demographic variables, but highly associated with depressive symptomatology.
- Familiar aggregation of insomnia in a sample of portuguese teachers.Publication . Almeida, Cristina; Pereira, Carlos; Veiga, Nélio; Amaral, Odete; Pereira, JoanaBackground: Insomnia is a common sleep disorder. Epidemiologic studies have linked the occurrence of insomnia with genetic and environmental factors. The aim of this study was to analyze the association between family history and other risk factors with the occurrence of insomnia in a sample of portuguese adults. Methods: In a cross-sectional study we assessed teachers of sixteen public elementary schools of the district of Viseu, Portugal. Data was collected using a self-administered questionnaire. We obtained a final sample of 864 teachers (631 female,73.0%), age=43.2±7.7 years. Insomnia was defined as the presence of one or more of the following symptoms: i)difficulty initiating sleep, ii)difficulty maintaining sleep, iii)early morning awakening and difficulty getting back to sleep, iv)non-restorative sleep, that lasts for a period of 1 month. Prevalence was expressed in proportions with 95% confidence intervals (CI), and compared by the chi-square test. Results: The prevalence of insomnia was 42.0% (95%CI=38.6-45.4). The prevalence of difficulty initiating sleep, difficulty maintaining sleep, early morning awakening with difficulty getting back to sleep, non-restorative sleep was 14.6% (95%CI=11.7-16.4), 29.4% (95%CI=26.5-32.7), 20.2% (95%CI=17.5-22.9) and 21.1% (95%CI=18.6-24.2), respectively. Insomnia was associated with gender (female, OR=1.3, 95%CI=1.0-1.8), use of any medication in the previous 12 months (OR=2.3,95%CI=1.7-3.2); depressive symptoms (OR=2.8,95%CI=1.8-4.3); sports practice (OR=0.8,95%CI=0.7-1.0); and drug consumption (OR=2.4,95%CI=1.3-4.6). After adjustment by non-conditional logistic regression for gender, use of medication, depressive symptoms and sports practice, the family history was associated with insomnia (OR=2.8,95%CI=1.38-5.76). Conclusion: Insomnia was associated with genetic factors, such as family history, and environmental variables.
- 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.
- Obesidade da genética ao ambientePublication . Amaral, Odete; Pereira, CarlosA obesidade é reconhecida pela Organização Mundial de Saúde (OMS) como um importante problema de saúde pública, afectando crianças, adolescentes e adultos (WHO, 1998). Os dados do International Obesity Task Force (2000) mostraram que, nos últimos anos, a prevalência de obesidade tem aumentado significativamente em várias regiões do mundo, sendo responsável, em grande parte, pelo aumento da mortalidade e morbilidade com implicações significativas no indivíduo, na família e na comunidade (Dietz et al, 1999; Cole et al, 2000).
- 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.
