- Effects of a personalized intervention program on the biochemical and hematological profile in community dwelling old adults-the AGA@4life intervention modelPublication . Caseiro, Armando; Rocha, Clara; Silva, Ana Margarida; Ferreira, Carla; Silva, Isabel; Clemente, Mariana; Cipriano, Inês; Saraiva, Marina; Barreira, Rogério; Azenha, Joana; Loureiro, Maria Helena; Martins, Anabela; Pereira, TelmoAging is a social and economic challenge of the highest importance and a multidisciplinary intervention seems to be a promising approach for improving the quality of life of elderly individuals. This project was designed aimed at promoting an active and healthy aging through the implementation of an intervention program based on the comprehensive geriatric assessment model (AGA@4life), focused on promoting health and wellbeing, independence and autonomy, mobility, and social inclusion. A non-randomized interventional study was designed to evaluate the effect of only a dietetic and nutritional approach (control group (CG)) and the combination of a tailored exercise program and a dietetic and nutritional approach (intervention group (IG)) in the biochemical and hematological profile of older adults in the framework of AGA@4life. The 34 participants enrolled, aged 65 years or over, were subject to a thorough baseline (T0) multidisciplinary diagnostic evaluation, including the gathering of clinical information and a battery of biochemical and hematological determinations, and reevaluated after eight weeks of intervention (T1). Between T0 and T1, an increase in albumin and total proteins serum levels were observed in both groups (p < 0.01); the hematological profile in CG and IG showed an increase in red cell count and hemoglobin (p < 0.05). In IG, an increase of HDL cholesterol (p < 0.001) and a decrease of triglycerides (p = 0.001) were still observed. The AGA@4life multidisciplinary intervention improved the hematological and biochemical profile of old adults, potentially contributing to delay the development of several aging comorbidities and increase the quality of life of participants.
- Impact of COVID-19 lockdown on the Portuguese population's physical activityPublication . Saraiva, Marina; Mendes, Rui; Cavaleiro, Alexandre; Marouvo, Joel; Brito, António; Castro, Maria AntónioIntroduction: Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. This disease harmed people's lives, compromising a healthy lifestyle. Objective: This study aims to analyze the impact of COVID-19 lockdown on the Portuguese population's physical activity and seated time during quarantine. Methodology: This retrospective longitudinal study was based on an online Google Forms survey concerning the lockdown period from 18th March to 30th April, 2020. A total of 541 responses were analyzed; all Portuguese (42.2 ± 14.8 years) completed the survey concerning the period. The valid responses were obtained from the 4th to 30th of May 2020. The physical activity during a week and the average seated time on a weekday before (T0) and during (T1) the quarantine were studied. Results: When comparing T0 and T1, there was a decrease in moderate-vigorous physical activity (p < 0.0001), walking time (p < 0.0001), and an increase in seated time (p < 0.0001), considering the whole sample group. All age groups decreased the time spent walking and increased the time seated. The highest value of seated time was displayed in the age interval of 26–35. Compared to the others, the age interval of 46—55 years showed the lowest values for vigorous and moderate activity. Conclusion: The first quarantine had a significantly negative effect on the Portuguese population's physical activity hours and contributed to a significant increase in the seating time during a weekday.
