The National Food, Nutrition and Physical Activity Survey of the Portuguese general population aimed to collect nationwide and regional data on dietary intake and physical activity, and their relation with health determinants, namely socioeconomic factors. Results from this project were obtained from a representative sample of the Portuguese population, aged between three months to 84 years of age, selected from the National Heath Registry, by multistage sampling (a sample size of 5068 individuals was estimated and 5811 participants with two dietary assessments were achieved). To accomplish the EFSA requirements, a minimum, of 260 individuals in each age group (130 by sex) was planned. Two face-to-face interviews were conducted at a health care centre or participant's home. Dietary intake was obtained by two non-consecutive days of food diaries for children (<10 years old) and two nonconsecutive 24-hours recalls for the older age groups, with a time interval between 8 and 15 days, complemented with a Food Propensity Questionnaire. An electronic platform based on a client-server architecture was used to manage the field work and to assist the data collection. The Electronic Assessment Tool for 24-hours recall (eAT24) allowed the collection of dietary data by an Automated Multiple-Pass Method for 24-hours. This interview-based dietary assessment instrument allowed obtaining a very detailed description and quantification of foods, recipes, and food supplements consumed in the course of the preceding day, and it had several adaptations, described in detail in this report. The survey outcomes support solid evidence-based information covering all age groups of the population, using harmonized methodologies at the European level, and will contribute to develop a national infrastructure for monitoring progress of specific targets supporting national and European policies and future interventions on diet, physical activity and food safety.

BACKGROUND The assessment of food consumption data using harmonized methodologies at the European level is fundamental to support the development of public policies. Portugal is one of the countries with the most outdated information on individual food consumption. OBJECTIVE The objective of this study was to describe the design and methodology of the National Food, Nutrition and Physical Activity Survey, 2015-2016, developed to collect national and regional data on dietary habits, physical activity (PA), and nutritional status, in a representative sample of the Portuguese general population (3 months-84 years). METHODS Participants were selected by multistage sampling, using the National Heath Registry as the sampling frame. Data collection, during 12 months, was harmonized according to European guidelines (EU-MENU, European Food Safety Authority [EFSA]). Computer-assisted personal interviewing (CAPI) was performed on a specific electronic platform synchronized with nutritional composition data and considering the FoodEx2 classification system. Dietary assessment was performed using 24-hour recalls (two nonconsecutive, 8-15 days apart) or food diaries in the case of children aged <10 years, complemented with a food propensity questionnaire; PA data (International Physical Activity Questionnaire [IPAQ], the Activity Choice Index [ACI], and 4-days PA diaries); sociodemographic data, and other health-related data were also collected. RESULTS A sample of 6553 individuals completed the first interview, and 5811 participants completed two dietary assessments. The participation rate among eligible individuals was 33.38% (6553/19,635), considering the first interview, and 29.60% (5811/19,635) for the participants with two completed interviews (about 40% in children and adolescents and 20% in elderly individuals). Results of the survey will be disseminated in national and international scientific journals during 2018-2019. CONCLUSIONS The survey will assist policy planning and management of national and European health programs on the improvement of nutritional status and risk assessment related to food hazards, and the enhancement of PA. The infrastructures and data driven from this Survey are a solid basis to the development of a future national surveillance system on diet, PA, and other health behaviors reproducible over time.

Health literacy, a more complex concept than knowledge, is a required capacity to obtain, understand, integrate and act on health information [1], in order to enhance individual and community health, which is defined by different levels, according to the autonomy and personal capacitation in decision making [2]. Medium levels of Health literacy in an adolescent population were found in a study conducted in 2013/2014, being higher in sexual and reproductive health and lower in substance use. It was also noticed that the higher levels of health literacy were in the area adolescents refer to have receipt more health information. The health literacy competence with higher scores was communication skills, and the lower scores were in the capacity to analyze factors that influence health. Higher levels were also found in younger teenagers, but in a higher school level, confirming the importance of health education in these age and development stage. Adolescents seek more information in health professionals and parents, being friends more valued as a source information in older adolescents, which enhance the importance of peer education mainly in older adolescents [3]. As a set of competences based on knowledge, health literacy should be developed through education interventions, encompassing the cultural and social context of individuals, since the society, culture and education system where the individual is inserted can define the way the development and enforcement of the health literacy competences [4]. The valued sources of information should be taken into account, as well as needs of information in some topics referred by adolescents in an efficient health education. Schizophrenia is a serious and chronic mental illness which has a profound effect on the health and well-being related with the well-known nature of psychotic symptoms. The exercise has the potential to improve the life of people with schizophrenia improving physical health and alleviating psychiatric symptoms. However, most people with schizophrenia remains sedentary and lack of access to exercise programs are barriers to achieve health benefits. The aim of this study is to evaluate the effect of exercise on I) the type of intervention in mental health, II) in salivary levels of alpha-amylase and cortisol and serum levels of S100B and BDNF, and on III) the quality of life and selfperception of the physical domain of people with schizophrenia. The sample consisted of 31 females in long-term institutions in the Casa de Saúde Rainha Santa Isabel, with age between 25 and 63, and with diagnosis of schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Physical fitness was assessed by the six-minute walk distance test (6MWD). Biological variables were determined by ELISA (Enzyme-Linked Immunosorbent Assay). Psychological variables were assessed using SF-36, PSPP-SCV, RSES and SWLS tests. Walking exercise has a positive impact on physical fitness (6MWD -p = 0.001) and physical components of the psychological test...

Introduction Evidence shows that sexual dysfunctions (SDs) are very prevalent in both sexes and that they share risk factors with many other conditions. It is known that only a minority of people experiencing sexual problems seek treatment, but the role of the general practitioner (GP) in SD diagnosis and treatment is relatively unexplored. No study has been conducted in Portugal in order to identify GPs’ knowledge, attitudes, beliefs, and practices regarding SD and only a small amount of similar studies from other countries have been published. Aim To characterize GPs’ knowledge, attitudes, and beliefs concerning SD; practices of SD management in daily practice; self-perceived competence in discussing and treating SD; and need for training. Methods Cross-sectional study using confidential self-administered questionnaires applied to GPs working in Primary Health Care Units in the Lisbon region. Main Outcome Measures The questionnaire collected information concerning GPs’ knowledge and perceptions regarding SD, training and practice in sexual health, criteria for initiating discussion and treatment, and the adoption of guidelines. Results A total of 50 questionnaires (30 females) were obtained (73.5% response rate). On average, the 50 participants were 52 ± 8.6 years old, had 21 ± 8.2 years of family practice, and followed 1,613 ± 364 patients. The degree in medicine was never considered as an extremely adequate source of information both for male and female SD. Lack of time to obtain relevant information for clinical practice and to deal with sexual health issues were perceived as important barriers in initiating a discussion with the patient, as well as lack of academic training and experience in this area. Conclusions GPs expressed a high need for continuous training in this area and more than half considered that their degree was not an adequate source of training. These results indicate that there is a need for both pregraduate and postgraduate training in this area.
