Prevalence of hypertension among the Portuguese population in a holiday context and multivariate analysis approach of risk factors through HJ-Biplot method: a pilot study. Rev Port Med Geral Fam [online]. 2019, vol.35, n.6, pp.450-464. ISSN 2182-5173.  https://doi.org/10.32385/rpmgf.v35i6.12319.

Purpose: The aim of the present study was to evaluate the prevalence of hypertension among the Portuguese population in a holiday context, as well as the relationship between blood pressure (BP) and risk factors, through the HJ-Biplot method. Type of study: Observational, descriptive, transversal-type, with a non-probabilistic sample (convenience). Local: Vilamoura. Population: Sample of both genders (≥ 18 years old). Methods: BP was measured in Vilamoura, from 30^th July to 5^th August 2017, in two distinct places: Praia da Falésia and Marina de Vilamoura. Around 1,000 people were evaluated, from different regions of the country (Portugal). BP measures, in mmHg, followed the protocol from Guidelines for the Management of Arterial Hypertension. Hypertension was defined as mean systolic BP (SBP) ≥ 140mmHg and/or diastolic BP (DBP) ≥ 90mmHg and/or use of antihypertensive medication if hypertension was known. A questionnaire was applied in informatic support with anthropometric parameters, associated pathologies, habits and life Styles. Protection and confidentiality of personal data were guaranteed. Results: The prevalence of hypertension was 33.3% of the studied population. Of those, 80.4% were aware of their health state and they were under antihypertensive therapeutic care, with 68.6% of those showing normal values for BP. There was a difference in the prevalence of hypertension according to gender and age, with males showing the highest values (M: 43.0% and F: 26.0%) as well as > 65-years-old people (76.2%). Multivariate analysis (HJ-Biplot) has allowed relating the increased prevalence of hypertension with some risk factors, mainly sex, age, body mass index (BMI), lifestyle (such as smoking habits and physical activity) or disease (such as diabetes or dyslipidemia). Conclusion: The results from the present study suggest, in comparison with other studies from Portuguese and world-wide population, the existence of a positive evolution towards reduction of the prevalence of hypertension, following an increased control, despite differences between populational subgroups, with inherent risk factors.
