Filter by:While it is well established that physical inactivity is a modifiable risk factor for vascular disease and cognitive decline, the mechanism by which exercise exerts its protective effect on the cerebral circulation and cognition is unknown. This knowledge gap was recognized recently in the Centers for Disease Control & Prevention and the Alzheimer's Association document "National Public Health Road Map to Maintaining Cognitive Health". Our rationale for these studies is that the identification of physical exercise as a lifestyle factor able to improve cerebrovascular reserve and cognition would establish a strong scientific framework justifying design of a randomized clinical trial that could evaluate the role of physical activity in cerebrovascular health and function. This research is based on data we obtained from a cross-sectional study that showed significant relations between physical fitness, vascular regulation and cognition. Cerebrovascular reserve and cognition were better maintained in women who were physically active but reduced in women who were sedentary. Our central hypothesis is that regular aerobic exercise mitigates age-related decreases in cerebrovascular reserve, which in turn imparts benefits in cognition. Further, we believe that these effects will persist after the structured aerobic exercise program is terminated. Our 18 month study began with a 6-month baseline period, followed by a 6-month exercise intervention, and a 6-month follow-up period. In addition, there are 5-year and 10-year follow-up periods. Volunteers (men and women aged ≥ 55 years) from the community were recruited using a variety of recruitment methods including media and distribution lists. After the baseline (pre-training) measurements, participants underwent a six-month aerobic training program, following guidelines previously used by us and according to the new exercise guidelines for older adults established by American College of Sports Medicine and the American Heart Association. The study involves comprehensive assessments of physical fitness, cerebrovascular responses to carbon dioxide at rest and during sub-maximal exercise, and an extensive battery of cognitive function tests.
The aim of the Stop Diabetes - Knowledge based solutions (StopDia) consortium project (University of Eastern Finland, National Institute for Health and Welfare, and Technical Research Centre of Finland) is to develop and test approaches to identify individuals at increased risk of type 2 diabetes and to empower them in adopting and maintaining a healthy lifestyle by combining individual and environment level strategies into a dual-process approach targeting deliberative and automatic processes of behavior. We also aim to identify barriers and facilitators of adopting a healthy lifestyle in the society, create a model for the prevention of type 2 diabetes by joint actions of health care, third sector, and other societal actors, and develop methods to monitor the cost-effectiveness of these actions. We will carry out a 1-year randomized controlled trial on the effects of among 10 000 individuals aged 18-70 years at increased risk of type 2 diabetes living in Finland. The participants will be randomized into the control group, the digital lifestyle intervention group, or the combined digital and face-to-face lifestyle intervention group. The aim of the interventions is to enhance diet quality, increase physical activity, decrease body weight, and improve glucose tolerance in individuals at increased risk of type 2 diabetes.
There is a high prevalence of inactive adults in the United Kingdom (UK), many of whom suffer from conditions such as diabetes, cardiovascular disease, and poor mental health. These problems often co-exist more frequently in areas of higher socio-economic deprivation. There is an ongoing need to test the effectiveness, acceptability, and sustainability of community physical activity interventions. The Active Herts programme is a community physical activity programme aimed at inactive adults aged 16 and over who have one or more risk factors for cardiovascular disease (CVD) and/or a mild to moderate mental health condition. The programme uses the latest evidence-based behaviour change techniques to target physical activity, wellbeing, and key drivers of behaviour from the COM-B ('Capability', 'Opportunity', 'Motivation' and 'Behaviour') model of behaviour change. This evaluation will follow a mixed-methods longitudinal (baseline, and 3, 6 and 12 month follow-ups) pragmatic observational design. Two types of programme are being delivered, each in a different area. In one, group participants will receive a behaviour change technique booklet, consultations (baseline, and optional at 3, 6, and 12 months), a booster phone call (week 2), motivational text messages (weeks 3, 6, and 12), and signposting to 12 weeks of exercise classes. In the other 'enhanced delivery' group, participants will receive the same but the 12 weeks of exercise will be free and tailored to their needs, and there will be optional exercise 'buddies' available. An outcome evaluation will assess changes in physical activity as the primary outcome, and sporting participation, sitting, wellbeing, psychological capability, and reflective motivation as secondary outcomes. A process evaluation will use both one-to-one interviews and focus groups to explore the views of stakeholders, delivery staff, and participants over three phases (set-up, deviations in the delivery of the intervention, and looking back over the intervention). Economic evaluation will examine the costs of the Active Herts programme against the benefits gained in terms of reduced risk of morbidity from a range of chronic conditions. This study will measure key drivers of physical activity using up to date behaviour change theory, allowing evaluation of not only whether physical activity has increased but also why. The research will inform the future development of a scalable intervention that can be more robustly tested in a randomised controlled trial.
The purpose of this study is to examine physical activity habit formation in parents and if this can increase moderate to vigorous physical activity behavior in their children over six months. The Primary Research Question is: Does the habit formation condition result in increased moderate-vigorous intensity physical activity of the child compared to the control (education) and education + planning conditions at six months? Hypothesis: Child physical activity will be higher for the habit formation condition in comparison to the more standard physical activity education and planning conditions at six months.
This trial will take the form of a feasibility study; designed to assess the feasibility of a proposed future clinical trial in this setting. This proposed future clinical trial is proposed to assess the impact of physical activity, in the form of specialised chair based physical activity interventions, on the physiological, psychological, cognitive, social and emotional health, and functional capacity of geriatric populations with pre-existing frailty within a clinical hospital ward setting; recognising health as a holistic concept incorporating a multitude of inter-related dimensions. This feasibility study is single-centre (taking place in the Harborne Ward of the Queen Elizabeth Hospital Birmingham, Mindelsohn Way, Edgbaston, Birmingham, United Kingdom).
Patients with COPD are more inactive and more sedentary than subjects of the same age and patients with other chronic diseases. This inactivity and sedentary behavior is accentuated after hospitalizations due to a COPD exacerbation, and it increases the risk for future hospitalizations and mortality. Therefore, there is a need for intervention to promote physical activity and to reduce sedentary behavior after these events. The present study aims to evaluate the efficacy of a coaching program to promote physical activity and reduce sedentary behavior in patients with COPD who have suffered a hospitalization due to a COPD exacerbation. Sixty-six COPD patients admitted to the hospital will be recruited during 18 months. Physical activity, sedentary behaviors, as well as other clinical and functional parameters will be evaluated after hospital discharge. Patients will be then randomized to an intervention and control group (1:1). The intervention group will receive an individualized coaching program. During a motivational interview an experienced physiotherapist will asses participant's usual exercise habits, possible barriers and facilitators, self-efficacy and motivation to increase physical activity and reduce sedentary time. Based on these data (and baseline physical activity/sedentary information) an individualized, progressive program with specific goals setting and self-monitoring will be established (patients will be active participants and decision makers in this process). The control group will receive the usual care during follow-up. Physical activity, sedentary behaviors, as well as the clinical and functional variables will be evaluated again at 12 weeks in both patients' groups.

The purpose of this study is to conduct a randomized controlled trial among 800 socially disadvantaged pregnant women and their families to test the effectiveness of a multi-component home visitation nutrition program, compared to usual care, in promoting healthy feeding practices, lifestyle behaviors and growth in young children.
In Hong Kong, nearly 40% of adults were overweight or obese, and about 60% of total registered deaths were due to four major preventable non-communicable diseases. Many residents are lack of attention to personal healthy lifestyle and family holistic health. This project focuses particularly on the promotion of healthy diet and physical activities enhancement in families through the well-established community network of the Hong Kong Island Women Association (HKIWA). This project includes three major components: Train-the-trainer and -ambassador workshop, community-based family interventions, and public education events. It is expected that knowledge and skills of the community leaders and ambassadors are strengthened through the 'Train-the-trainer and -ambassador' (TTTA) workshops. Furthermore, they are expected to help the implementation of community-based family interventions and public education events on the personal and family holistic health of the community participants.
Despite physical activity (PA) being a valuable modality for promoting health, the evidence for effective PA intervention strategies for manual wheelchair (MWC) users is underdeveloped. Community-based programs and telephone-counselling interventions to increase PA among MWC users have had some success, but the uptake and adherence to these interventions remains low within this population. Community-based programs may not reach MWC users who live in rural areas and have issues with transportation, while health professionals may not optimally relate with MWC when providing telephone counselling. Although the PA needs of MWCs are not fully understood, there is reason to believe that including peers into intervention delivery may have benefits. A feasibility trial is critical and prudent prior to moving forwards with a large and expensive multi-site randomized controlled trial (RCT) to ensure that: the intervention meets the needs of the target population; the right outcomes are measured; and that the intervention is feasible to administer. The objective of this study is to evaluate the feasibility of a Smartphone-delivered Peer-led Physical Activity Counselling (SPPAC) program for MWC users.
