Interrelationship between arterial hypertension, health service costs, therapeutic treatment and physical activity.

Background: Arterial hypertension is a high prevalence disease that increase healthcare costs and affects physical activity level. This study aimed to analyse the interrelationship between arterial hypertension, health service costs, therapeutic treatment, and physical activity in patients with cardiovascular diseases.

Method: Cross-sectional study that evaluated 306 patients from a hospital in Presidente Prudente-Brazil.

Physical training improves physical activity levels but is associated with amplification of sedentary behavior in older women.

Physical activity level (PAL) and sedentary behavior (SB) are independent predictors of mortality. It is unclear how these predictors interact with each other and health variables. Investigate the bidirectional relationship between PAL and SB, and their impact and health variables of women aged 60 to 70 years.

Development and Psychometric Evaluation of a Lifestyle Evaluation Instrument for Older Adults.

Brazil is experiencing an accelerated period of population aging, with important implications for individuals, families, and the society at large. Lifestyles for the elderly can have both positive and negative health effects and are characterized by behaviors that individuals constantly reproduce in day-to-day life. However, few assessment instruments are aimed at evaluating lifestyles, and this has hampered research development.

25-hydroxyvitamin D in older adults: Which factors really matter?

Background And Objectives: This study investigated the interaction between a set of factors commonly associated with vitamin D production and nutritional intake and serum 25(OH)D levels among older adults.

Methods: Cross-sectional study on 346 adults over 60 years. Serum 25(OH)D levels were measured following routine biochemical laboratory protocols.

ADAM10 plasma levels predict worsening in cognition of older adults: a 3-year follow-up study.

Background: Blood-based biomarkers for Alzheimer's disease (AD) are highly needed in clinic practice. So far, the gold standards for AD diagnosis are brain neuroimaging and beta-amyloid peptide, total tau, and phosphorylated tau in cerebrospinal fluid (CSF); however, they are not attractive for large-scale screening. Blood-based biomarkers allow an initial large-scale screening of patients under suspicion that could later be tested for the already established CSF biomarkers.

Studies About Physical Activity Interventions Including Follow-Up Analysis: A Systematic Review.

Background: Some studies have used the follow-up method to analyze real behavioral changes in research involving physical activity (PA) interventions. This has great scientific value; however, it is hard to apply without satisfactory resources and research funding. Little is known about how many studies have used this method to analyze PA interventions in low-income and middle-income countries, especially Brazil.

Evaluating the impact of a walking program in a disadvantaged area: using the RE-AIM framework by mixed methods.

Background: The positive health impact of physical activity (PA) is well known, yet a large proportion of the world's population remains sedentary. General PA programs are common as health promotion initiatives. However, effectiveness evaluations of such PA programs on individual and organizational aspects, which could inform the decision-making process of public health bodies are still lacking, particularly in the most socially disadvantaged areas, where health promotion schemes are particularly needed.
