Systolic Blood Pressure and Its Determinants: Study in a Population Attending Pharmacies in a Portuguese Coastal City

Hypertension is a common condition causing cardio and cerebrovascular complications. Portugal has one of the highest mortality rates from stroke and a high prevalence of hypertension. Systolic Blood Pressure (SBP) is an important risk factor for cardiovascular events (myocardial infarction and stroke) and premature mortality, particularly in the elderly population. The present study aims to estimate the prevalence of hypertension in a Portuguese population living in a coastal city and to identify some of its determinants (namely gender, age, the body mass index and physical activity frequency). A total of 91 adults who attended three pharmacies of a coastal city in the center of Portugal, between May and August of 2013 were evaluated. Attendants who reported to have diabetes or taking antihypertensive drugs in the 2 previous weeks were excluded from the study. Sociodemographic factors, BMI, habits of exercise and BP were assessed. Hypertension was defined as blood pressure ≥140/90 mmHg. The majority of the studied population was constituted by women (75.8%), with a mean age of 54.2±1.6 years old, married or living in civil union and that had completed secondary school or had higher education (40%). They presented a mean BMI of 26.2±4.76 Kg/m2., and were sedentary. The mean BP was 127.0±17.77mmHg- 74.69 ± 9.53. In this population we found 4.3% of people with hypertension and 16.1% with normal high blood pressure. Men exhibit a tendency to present higher systolic blood pressure values than women. Of all the factors considered, SBP values also tended to be higher with age and higher BMI values. Despite the fact that the mean values of SBP did not present values higher than 140 mmHg we must be concerned because the studied population is undiagnosed for hypertension. Although this is a preliminary study, it might be a prelude to the upcoming research about the underlying factors responsible for the occurrence of SBP.

A new inhight on the Portuguese traditional sweets as cultural identity: a scientific approach towards evaluation of texture in Castanhas de Ovos de Viseu

The importance of the gastronomic heritage of any people is unquestionable and Portugal is particularly rich when it comes to sweets. Hence, the objective of this work was to give a contribution colour and texture, due to their importance for consumer acceptance. The samples were bought from a pastry in Viseu and produced according to the traditional recipe. Colour evaluation was made by a colorimeter and textural analysis by a texturometer. The results obtained allowed concluding that there were differences between the top burned area and the non-burned areas, as well as when comparing the ruffled with unruffled samples either regarding colour and also texture. The burned area was darker, with a more intense red and less yellow. As to texture, the ruffles samples were harder than the unruffled samples.

Factors Affecting the Body Mass Index in Adolescents in Portuguese Schools

The prevalence of overweight and obesity among children is increasing; hence, it was aimed to assess the Body Mass Index (BMI) in school children aged from 10 to 18 years for girls and to 17 for boys, as well as to identify the factors influencing BMI. This study included 742 students who answered a questionnaire previously approved for application in schools. The results showed some sociodemographic factors associated with BMI classes: age, school year, practicing high competition sport, being federate in a sport or having a vegetarian diet. The educational factors associated with BMI classes included only seminars given at school by a nutritionist. Behavioural factors significantly associated with BMI included: learning in classes, playing in the open air, reading books or use of internet. As conclusion, the results demonstrated that several factors affect BMI, and hence some actions could be taken in order to change them so as to reduce the prevalence of overweight, namely reinforcing the role of school and a more active participation of nutritionists in the education of the adolescents.

Perception of health benefits of dietary fibre among the Portuguese population

Introduction: Dietary iber (DF) has been part of human diet since ever, and its beneits for the human health have been well estab-lished and scientiically conirmed. Among these stand improved gastrointestinal functions, prevent cholesterol, diabetes or CVD. Objectives: To study the level of knowledge of people residing in Portugal about the health effects related to an adequate ingestion of DF. Methods: This is a descriptive cross-sectional study carried out on a non-probabilistic sample of 382 adults residing in Portugal. The questionnaire included a section about the socio-demographic characteristics (age, gender, level of education and living environ- ment) and another about the relation between dietary iber and possible beneicial effects to treat and prevent diseases. The data was treated using the SPSS software (V22). Results: The results allowed concluding that people were dif- ferently informed about the effects of DF in preventing and/or treating different diseases, being constipation the most recog- nized, followed in decreasing order by obesity, bowel cancer, cholesterol, cardiovascular diseases, diabetes and breast can- cer. The results also showed that signiicant differences were encountered between age groups for most of the diseases evalu- ated, but not between genders, levels of education or living en- vironments. Conclusions: Generally, it was concluded that the participants in this study were relatively well informed about the roles of DF in preventing and/or treating various diseases.

Avaliação nutricional dos idosos institucionalizados no concelho de Viseu

O envelhecimento da população, bem como a alteração da dinâmica da família, têm contribuído diretamente para o aumento do número de idosos institucionalizados. A incidência da desnutrição alcança níveis elevados nestes idosos, sendo essencial o seu diagnóstico precoce para a melhoria da sua qualidade de vida. Constitui objetivo primordial do estudo a avaliação do estado nutricional de idosos institucionalizados no concelho de Viseu, Portugal. A amostra (n=120) é constituída por idosos de ambos os sexos, institucionalizados, com idade igual ou superior a 65 anos, com capacidade para se colocar de pé, sem demência e que não sejam portadores de patologia passível de afetar a digestão, absorção ou utilização dos nutrientes. A avaliação do estado nutricional é determinada tendo em conta parâmetros antropométricos, a aplicação do e Mini Nutricional Assessment (MNA) e dietéticos, através da avaliação da ingestão alimentar (registo de 3 dias). Os questionários aplicados estão validados para a população portuguesa idosa e foram aplicados após consentimento informado. Foram realizadas estatísticas descritivas e inferenciais às diferentes variáveis, de acordo com o género e estratos etários. Considerou-se um nível de confiança de 95%. Dos 120 indivíduos estudados 30% eram do sexo masculino e 70% eram do sexo feminino. As médias das idades eram de 82,36 ± 6,34 anos. A determinação do IMC mostrou que 12,5% dos idosos avaliados exibem baixo peso (IMC 19,6±2,1); 46,7% são eutróficos (IMC 25,7±1,3); 11,7% apresentam excesso de peso (IMC 29,0±0,6), sendo 29,2% classificados como obesos (IMC 33,8±2,9).A avaliação da população pelo MNA evidenciou uma percentagem de desnutrição de 1,7% com uma prevalência de risco de desnutrição (33,3%) mas identifica 65% da amostra como bem nutrida. Os 2 instrumentos utilizados para avaliação do estado nutricional, antropometria (IMC) e MNA mostraram uma correlação estatística entre si positiva. Independentemente do género e do grupo etário verificou-se que o Valor Calórico Total (VCT) ingerido diariamente apresentava valores abaixo do recomendado. Já a ingestão diária de hidratos de carbono e de proteínas apresentou valores médios superiores às recomendações nutricionais enquanto os teores de lípidos ingeridos se situava dentro dos limites recomendados estando porém os valores da ingesta média de fibra total (18g/dia) abaixo dos indicados para a população idosa (25g/dia). Quanto aos micronutrientes encontraram-se deficits de ingestão média diária de minerais e oligoelementos como o cálcio, ferro, magnésio selénio, zinco e iodo e também de algumas vitaminas (D, E, ácido fólico). Conclui-se então que no geral a população estudada apresenta um estado de nutrição normal avaliado através de IMC e do MNA dois instrumentos que estão correlacionados entre si e se complementam. Que a ingestão alimentar apresentada pelos idosos desta amostra é apenas ligeiramente inferior ao recomendado, não colocando em risco o aparecimento de desnutrição. Porém é importante a intervenção dietética no sentido de corrigir determinadas carências (vitaminas, minerais) e prevenir o risco de desnutrição detetado assim como a obesidade.

Parental Adjustment to Disability, Stress Indicators and the Influence of Social Support

Research into families of children and young people with disability maintain that parents or caregivers seem to experience higher levels of global stress than parents of children without disabilities, thereby presenting a high risk of developing disorders in their health and quality of life. The aim of this study is to understand the differences in parental stress and social support among groups of parents whose children have different disabilities in the context of parental adjustment to disability. Considering that adjustment is related to the effectiveness with which the family uses its resources and the support of their social network, we intend to analyse the differences of stress and social support among groups of parents of children with different problems and to clarify the relationships between the variables under study in order to adapt family intervention strategies. For this purpose a comparative, descriptive-correlational study was undertaken. The convenience sample included 152 parents of children with different disabilities (82 with intellectual disability, 37 with motor problems and 33 with autism) supported by schools and institutions in Viseu. The instruments used were: a Portuguese version of the Parenting Stress Index (Abidin, 1995), the Social Support Questionnaire – short version (Pinheiro & Ferreira, 2001) and a Parental Questionnaire (demographic and family data). Data were collected in schools and institutions that support people with disabilities, located in the Municipality of Viseu (Portugal). The results revealed significant differences between groups of parents in the partial results of parental stress, specifically in the Hyperactivity/Distract (DI), Acceptability (AC) and Adaptability (AD), dimensions of the Child Domain subscale (CD stress) and the Role Restriction (RO), dimension of Parent Domain subscale (PD stress). With regard to social support dimensions, we found significant differences between parents in the extent and availability of the social support network (SSQN).
