- Cross-sectional and prospective relationship between physical activity and chronic diseases in European older adultsPublication . Marques, Adilson; Peralta, Miguel; Martins, João Filipe da Silva Figueira; Matos, Margarida Gaspar de; Brownson, Ross C.Objectives This study examined the relationship between physical activity (PA) and chronic diseases in European older adults, using a prospective analysis with data from 2011 and 2013. Methods Participants were 37,524 older adults (16,204 men) who responded to the fourth (in 2011) and fifth (in 2013) wave of SHARE project, from 13 European countries. Participants’ answers to interview questions about the presence of chronic conditions and PA. The cross-sectional and prospective association between PA and the number of chronic diseases was assessed using general linear models. Results Among men and women, moderate or vigorous physical activity (MVPA) in 2011 was associated with fewer reported chronic diseases in 2011 and 2013. In prospective analysis, MVPA in 2011 was inversely associated with the number of chronic diseases in 2013 in the unadjusted model. In the adjusted model MVPA more than once a week remained as a significant predictor of fewer chronic diseases. Conclusions PA should be prescribed to older adults in order to prevent and reduce the number of chronic diseases, and, when possible, vigorous intensity PA should be recommended.
- Pressure ulcer risk profiles of hospitalized patients based on the Braden Scale: A cluster analysisPublication . Gaspar, Susana; Peralta, Miguel; Budri, Aglécia; Ferreira, Carlos; Gaspar de Matos, Margarida; Gaspar de Matos, MargaridaThe aim of this work is to identify the pressure ulcer risk profiles of hospitalized patients with reference to Braden Scale subscales. Methods: A total of 2996 hospitalized Portuguese participants were screened using the Braden Scale. A hierarchical and nonhierarchical cluster analysis was conducted, with ethical approval. Five risk profiles (clusters) based on the first risk assessments were identified. Regarding the Braden Scale total score, two profiles with high risk and three profiles with low risk of pressure ulcer development were identified. All clusters were statistically significantly different in terms of sociodemographic and clinical variables. When the first and the last risk assessments were compared, all the clusters improved the Braden Scale total score on the last risk assessment, except Cluster 4 (low‐risk category). Clusters 3, 4 and 5, which were classified as low risk, decreased in several Braden subscales at the last risk assessment.Conclusions: The classification of low risk may misguide the early identification of patients with individual risk factors. Increasing the awareness of health care professionals for the importance of risk assessment of each Braden subscale is necessary for pressure ulcer prevention. We recommend the implementation of strategies for early identification of patients at risk at local and national levels.
- Prevalence of adult overweight and obesity in 20 european countries, 2014Publication . Marques, Adilson; Peralta, Miguel; Naia, Ana; Loureiro, Nuno; Matos, Margarida Gaspar deBackground: Monitoring obesity and overweight prevalence is important for assessing interventions aimed at preventing or reducing the burden of obesity. This study aimed to provide current data regarding the prevalence of overweight and obesity of adults, from 20 European countries. Methods: Participants were 34 814 (16 482 men) adults with mean age 50.8 17.7. Data from European Social Survey round 7, 2014, were analysed. Body mass index (BMI) was calculated from self-reported height and weight. Results: The proportion of underweight was only 2%, and 44.9% for normal weight. Overweight and obese accounted for 53.1%. More men than women were overweight (44.7% vs. 30.5%). Older adults were significantly more overweight (42.4%) and obese (20.9%) than middle age and younger adults. Retired people account for a greater proportion of overweight (42.0%) and obese (21.5%), when compared with employed, unemployed and students. People from rural areas were significantly more overweight (39.1 vs. 36.1%) and obese (17.0 vs. 15.3%) than those who lived in urban areas. The estimates indicate that the highest prevalence of overweight was in Czech Republic (45.2%), Hungary (43.7%) and Lithuania (41.7%). For obesity, Slovenia (20.8%), Estonia (19.7%) and the United Kingdom (19.2%) were the countries with the highest prevalence. Conclusion: Even though data was self-reported, and individuals tend to overestimate their height and underestimate their weight, the prevalence of overweight and obesity is considered high. More than half of the European population is overweight and obese. This study strengthens and updates the claims of an excessive weight epidemic in Europe.
