- The association between exposure to blue spaces and multidimensional frailty in community-dwelling older adults: A cross-sectional studyPublication . Coelho, Tiago; Leite, Diana; Maciel, Daniela; Ribeiro, Ana Isabel; Rocha, Nuno Barbosa; Rocha, Nuno; Coelho, TiagoContact with blue spaces appears to benefit older adults’ health and well-being, but evidence on its relationship with frailty is scarce. This cross-sectional study investigated associations between exposure to blue spaces and multidimensional frailty in 189 community-dwelling people aged ≥65 years (Portugal). Measurements included the Tilburg Frailty Indicator, questionnaire regarding exposure, and Geographic Information System data for proximity. Purposeful visits once or twice a month were associated with lower physical frailty, as were visits with pets, engaging in physical activity, and spending 1–2 hours or >2 hours in these environments. Visiting with others was associated with lower social frailty. Incidental exposure—passing by visible blue spaces during daily commutes—was linked to lower total and physical frailty. Walking travel times <20 minutes were associated with lower total, physical, and social frailty, with different distances within this range showing domain-specific associations. Results suggest blue spaces may promote healthy aging.
- Movement behaviours, air pollution and health in school-aged children: a cross-sectional study to guide the co-creation of healthier environments – the MOVE-AIR projectPublication . Martins, Clarice; Rufo, João Cavaleiro; Fonseca, Hélder; Padrão, Ana; Baptista, Liliana C.; Santos, Maria Paula; Sousa, Miguel; Zacca, Rodrigo; Silva, José Pedro; Ribeiro, Ana Isabel; Cavaleiro Rufo, JoãoThe MOVE-AIR study was designed to explore the moderating role of movement behaviours on the association between air pollutants and health outcomes in Portuguese children. Secondarily, it aims to characterise the settings (both indoor and outdoor) where children are exposed to air pollutants and to co-create solutions with participants to mitigate the exposure to air pollutants in children’s daily life. This study aims to describe the MOVE-AIR study protocol in detail. Data from 52 primary school children aged 9–11 years will be assessed for indoor and outdoor air pollutants (particulate matter (PM)2.5 and PM10, and carbon dioxide), geo-tracked for distinct settings (ie, home/school, indoor/outdoor) along the day, through an optical monitoring sensor with Global Positioning System incorporated. Health-related biological outcomes, such as interleukin-6, tumour necrosis factor alpha and oxidative parameters, including total antioxidant status and total oxidant status, will be evaluated and the Oxidative Stress Index will be calculated. Children’s cardiopulmonary fitness will be assessed through the shuttle run test, and movement behaviours will be evaluated through accelerometers (wGT3X). Children’s sex, age and parental socioeconomic status will be provided by parents through a questionnaire. The influence of movement behaviours in the link between pollution and health will be analysed through moderating regression models using process for SPSS R software (V.30.0.0). A subsample of class teachers, school leaders, parents and children will be invited to a co-creation process to create solutions to mitigate their daily exposure to air pollutants. The results will contribute to further understanding the moderating role of movement behaviours in the association between air pollution and health, adding a biological layer to the mechanistic links underlying these potential relationships that have not been explored in this target population. Finally, enhancing our comprehension of the living environments and contexts where children are more exposed to air pollution can help to cooperatively create solutions to mitigate their daily exposure to those harmful pollutants.
- Osteoporotic hip fractures: Bisphosphonates sales and observed turning point in trend. A population-based retrospective studyPublication . Alves, Sandra Maria; Economou, Theodoros; Oliveira, Carla Maria; Ribeiro, Ana Isabel; Neves, Nuno; Goméz-Barrena, Enrique; Pina, Maria de FátimaThe aim is to examine the temporal trends of hip fracture incidence in Portugal by sex and age groups, and explore the relation with anti-osteoporotic medication. From the National Hospital Discharge Database, we selected from 1st January 2000 to 31st December 2008, 77,083 hospital admissions (77.4% women) caused by osteoporotic hip fractures (low energy, patients over 49 years-age), with diagnosis codes 820.x of ICD 9-CM. The 2001 Portuguese population was used as standard to calculate direct age-standardized incidence rates (ASIR) (100,000 inhabitants). Generalized additive and linear models were used to evaluate and quantify temporal trends of age specific rates (AR), by sex. We identified 2003 as a turning point in the trend of ASIR of hip fractures in women. After 2003, the ASIR in women decreased on average by 10.3 cases/100,000 inhabitants, 95% CI (− 15.7 to − 4.8), per 100,000 anti-osteoporotic medication packages sold. For women aged 65–69 and 75–79 we identified the same turning point. However, for women aged over 80, the year 2004 marked a change in the trend, from an increase to a decrease. Among the population aged 70–74 a linear decrease of incidence rate (95% CI) was observed in both sexes, higher for women: − 28.0% (− 36.2 to − 19.5) change vs − 18.8%, (− 32.6 to − 2.3). The abrupt turning point in the trend of ASIR of hip fractures in women is compatible with an intervention, such as a medication. The trends were different according to gender and age group, but compatible with the pattern of bisphosphonates sales.
