Filter by:The aim for the study is to use the function WeRun in the application WeChat to encourage physical activity and social engagement among community dwelling older adults and their family members and friends. The specific aims are to test the effectiveness of a social contact and comparison intervention for increasing regular daily physical activity among community dwelling older adults, and to examine the potential effectiveness of WeChat in cultivating social engagement and well-being among community dwelling older adults.
This renewal builds upon our successful culturally adapted PA intervention for Latinas (Pasos Hacia La Salud, R01CA159954) and expands its focus to the critical area of maintenance of behavior change. This study will test an enhanced version of the original internet intervention in order to achieve greater increases in PA and longer term maintenance. Investigators propose to test this newly developed enhanced intervention (Enhanced Intervention) compared to the original Pasos Hacia La Salud Intervention (Original Intervention) in a 24-month randomized trial (N=300).
The overall goals of this renewal are to replicate the findings of Seamos Saludables in Latina women, increase the effectiveness of the intervention, and measure intervention-related changes in clinical biomarkers. We will enhance the existing intervention by incorporating participant feedback (desire for greater interactivity and accountability), further targeting Social Cognitive Theory (SCT) constructs that were not influenced overall by the original intervention yet improved amongst our most successful participants (social support, outcome expectancies), and responding to changing trends and technology use in Latinos. We will conduct a clinical trial among Latina women in California randomized to either 1) the original Seamos Saludables tailored print only intervention or 2) a theory and text messaging-enhanced interactive technology based version of the Seamos Saludables intervention. We will also measure changes in cardiovascular and metabolic biomarkers (e.g., HbA1c, and LDL) to assess potential clinical impact of the intervention.
The aim of this study is to build upon our tailored print intervention by developing new text-delivered intervention materials to complement our print-based physical activity (PA) intervention. In Phase 1 we will conduct 6 focus groups with Mexican and Mexican American (MA) men to determine content, frequency, and types of text messages desired, and to identify cultural themes to incorporate into existing and new materials. Themes from the focus groups and sample text messages will be presented to a confirmatory focus group panel. Phase 2 will be a 6-month pilot randomized controlled trial with Mexican and MA men (N=60) to test the text-enhanced, Spanish language, individually tailored PA intervention vs. publicly available, Spanish language health education materials, including information on PA, diet, and stress management. This will be followed by post-intervention qualitative interviews to solicit suggestions for improvements to help further refine the program. The proposed pilot will support a future R01 to establish the efficacy of this multi-media, multi-level PA intervention for Mexican and MA men.
The present study used a cluster-randomized controlled trial to evaluate the effects of a computer-tailored, pedometer-based Physical Activity (PA) intervention delivered through the Internet. An invitation e-mail with study information was sent to managers of 18 white-collar workplaces. Eight workplaces consented to participate. All employees of a single workplace were allocated at random to either the intervention or a waiting list control group, in order to avoid contamination between employees receiving the intervention and those who were not receiving the intervention. Subsequently, employees of the participating workplaces were recruited by e-mail. Only Dutch speaking employees between 18 and 65 years old, who had access to the Internet at work or at home, were eligible. Interested employees could sign up by returning a confirmation e-mail to the researchers. On receiving this information, a meeting was organized in each of the eight worksites to deliver all documents for baseline measurement (T0) to the participants, including an informed consent form, a blinded pedometer, an activity log and a self-administered questionnaire. During this meeting, information was provided on how to use the pedometer, how to log PA activities and how to answer the questionnaire. Moreover, the participants were asked to adhere to their usual PA pattern throughout the baseline measurement. After one week, all measurement tools were collected, and average daily step counts were calculated. At this point, participants in the intervention condition received (1) a booklet with information on how to increase steps, (2) a non-blinded pedometer, which they could use for three months, and (3) a username, a password and the amount of average daily steps, calculated by the researchers, so that participants could use this number when requesting the online computer-tailored step advice. Participants in the control condition did not receive any of the above mentioned intervention components. One and three months later, all participants again received a blinded pedometer, which was worn for one week. When wearing the blinded-pedometer one month (T1) and three months (T2) post baseline, intervention participants were allowed to also were the non-blinded pedometer. Furthermore, the same self-reported questionnaire was used to measure PA level at T1 and T2 in order to test the effectiveness of the intervention.
In this study, investigators are specifically targeting Latina women as they are more likely to be inactive and, therefore, are at higher risk for developing chronic conditions such as obesity, diabetes, or cardiovascular disease. The objective of Pasos Hacia La Salud is to test a Spanish-language Internet-based Physical Activity Intervention, in comparison to a Spanish-language Internet-based Wellness Contact Control condition. Participants are randomly assigned to one of two groups (Exercise and General Wellness). The investigators hypothesize that at the end of treatment, intervention participants will report significantly more minutes of moderate intensity physical activity per week than the wellness contact control participants.
Epidemiological studies as well as both longitudinal animal and human inactivity studies indicate that low physical activity is associated with the pathophysiology of type 2 diabetes mellitus (T2DM) and obesity, and recently it has been estimated that physical inactivity (worldwide) causes 7% of the burden of disease related to e.g. T2DM. Physical inactivity, a high energy dietary intake, and T2DM are also associated with dementia, depression, and impaired cognitive function. It is critical that we understand how inactivity alters body composition, glucose and lipid metabolism, and cognitive function, if normal physical activity can prevent these changes, and if there are any differences between sexes. The present protocol is divided in several in several sub-studies: 1. To test whether and how a physically inactive lifestyle will influence body composition, glucose and lipid metabolism, and cognitive function. 2. To test whether normal physical activity can prevent the deleterious effect of a physically inactive lifestyle despite a high-caloric intake. 3. To test whether the influence of a physically inactive lifestyle combined with a high-caloric intake differs between sexes.
The aim of this study is to increase our knowledge about the effect of physical activity in patients who have undergone gastric bypass surgery. The study will provide novel information in two areas. The main objective is to study the effect of physical activity on the weight loss and cardiovascular risk factors. This will be accomplished in a randomized clinical trial in patients, who are eligible for gastric bypass (GB). Patients will be randomized to six month of structured physical activity or standard postoperative counseling. The study will include an exhaustive panel of blood tests related to cardiovascular risk and the most extensive evaluation of structural and functional vascular test done in this patient group so far. In addition the study will provide information of the effect of bariatric surgery per se since both pre- and postoperative investigations are conducted. The study will learn us to what degree it is possible to motivate this group of patients to increased physical activity. All together this will enable us to improve the counseling of the patients undergoing GB.
The incretin effect in patients with type two diabetes is reduced. The investigators have previously shown that it is possible to induce a defect in the incretin effect in healthy individuals. The purpose of this study is to evaluate the insulinotropic affect of the incretin hormones in healthy individuals before and after a deterioration of the glucose homeostasis.
The purpose of the study is to evaluate the effect of a project promoting unstructured spontaneous physical activity (PA) through an adaptation of the built environment and the provision of a supportive social environment of childcare centers on motor skills, physical activity, desire to move around, body mass index (BMI), quality of life and PA and behavior of the family.
