Change in physical activity after a diabetes diagnosis: opportunity for intervention.

ABSTRACT: Moderate-intensity physical activity is recommended for individuals with diabetes to control glucose and prevent diabetes-related complications. The extent to which a diabetes diagnosis motivates patients to increase physical activity is unclear. This study used data from the Women's Health Initiative Observational Study (baseline data collected from 1993 to 1998) to examine change in physical activity and sedentary behavior in women who reported a diabetes diagnosis compared with women who did not report diabetes during 7 yr of follow-up (up to 2005).Participants (n = 84,300) were postmenopausal women who did not report diabetes at baseline (mean ± SD; age = 63.49 ± 7.34 yr; body mass index = 26.98 ± 5.67 kg·m). Linear mixed-model analyses were conducted adjusting for study year, age, race/ethnicity, body mass index, education, family history of diabetes, physical functioning, pain, energy/fatigue, social functioning, depression, number of chronic diseases, and vigorous exercise at age 18 yr. Analyses were completed in August 2012.Participants who reported a diabetes diagnosis during follow-up were more likely to report increasing their total physical activity (P = 0.002), walking (P < 0.001), and number of physical activity episodes (P < 0.001) compared with participants who did not report a diabetes diagnosis. On average, participants reporting a diabetes diagnosis reported increasing their total physical activity by 0.49 MET·h·wk, their walking by 0.033 MET·h·wk, and their number of physical activity episodes by 0.19 MET·h·wk. No differences in reported sedentary behavior change were observed (P = 0.48).A diabetes diagnosis may prompt patients to increase physical activity. Healthcare professionals should consider how best to capitalize on this opportunity to encourage increased physical activity and maintenance.

Project description:Challenges exist in identifying, recruiting and motivating sedentary patients with cancer to initiate physical activity towards recommended levels. We hypothesise that the onset period of adjuvant chemotherapy can be 'the open window of opportunity' to identify and motivate sedentary patients with breast and colon cancers, at risk for developing coronary heart disease, to initiate and sustain lifestyle changes.To investigate the feasibility of oncologists/nurses screening for physical inactivity, in order to identify and recruit an at-risk population of sedentary patients with breast or colon cancer at the onset of adjuvant chemotherapy. Furthermore, the study will examine the adherence to one of two multimodal exercise interventions lasting 12 weeks; (1) hospital-based, high intensity, group exercise intervention (2) home-based, low intensity, individual, pedometer intervention. Both arms will be compared with a control group.All newly referred patients will be screened for sedentary behaviour, using national recommendations. Testing at baseline, 6, 12 and 39 weeks will include; (1) physiological testing (VO2-peak, one repetition maximum muscle strength and lung function (2) fasting full body dual-energy X-ray absorptiometry scan (3) fasting blood glucose, insulin, lipids and cholesterols, (4) psychometric questionnaires (general well-being, quality of life, anxiety and depression, motivational readiness). The randomised controlled trial feasibility design is selected in order to examine barriers for recruitment, programme adherence, safety aspects and potential efficacy to the interventions during adjuvant chemotherapy.The Scientific Committee of the Capital Region (case No. H-1-2011-131) and the Danish Data Protection Agency (j. No. 2011-41-6349) approved the study. Data will be entered and locked into a database hosted by the Copenhagen Trial Unit, Rigshosptialet. Data will be available for analyses to project members and the trial statistician after the 45 included patients have completed the 12-week test. Results will be published in peer-reviewed scientific journals.Current Controlled Trials ISRCTN24901641.

Project description:BackgroundEndometrial cancer survivors are at an increased risk of poor quality of life outcomes. Physical activity is positively associated with general quality of life in this population, however, little is known about how changes in physical activity may be associated with changes in specific aspects of quality of life. The aim of this secondary data analysis was to explore the relationships between change in physical activity and change in physical, mental, social, and other aspects of quality of life in endometrial cancer survivors receiving a physical activity intervention.MethodsEndometrial cancer survivors (N = 100) participated in a telephone-based physical activity intervention for six months. At baseline and post-intervention we measured physical activity via accelerometry and ecological momentary assessment, and quality of life via the Short Form Health Survey (SF-36), the Quality of Life of Adult Cancer Survivors instrument, the Brief Symptom Inventory, the Pittsburgh Sleep Quality Index, and the Perceived Stress Scale. We conducted structural equation modeling path analyses to investigate how physical activity post-intervention was associated with the quality of life measures' subscales post-intervention, adjusting for baseline levels and potentially confounding covariates.ResultsIncreasing physical activity was positively associated with improvements in general health (p = .044), role limitation due to physical health (p = .005), pain (p = .041), and somatic distress (p = .023). There was no evidence to indicate that change in physical activity was associated with change in other aspects of quality of life.ConclusionsEndometrial cancer survivors are at higher risk for suffering from challenges to physical quality of life, and findings from this study suggest that increasing physical activity may alleviate some of these problems. Further research is needed to determine whether other aspects of quality of life are linked to change in physical activity.Trial registrationTrial registration number: NCT00501761 Name of registry: clinicaltrials.gov Date of registration: July 16, 2007.

Project description:Low childhood physical activity levels are currently one of the most pressing public health concerns. Numerous school-based physical activity interventions have been conducted with varied success. Identifying effective child-based physical activity interventions are warranted. The purpose of this formative study was to elicit subjective views of children, their parents, and teachers about physical activity to inform the design of the CHANGE! (Children's Health, Activity, and Nutrition: Get Educated!) intervention programme.Semi-structured mixed-gender interviews (group and individual) were conducted in 11 primary schools, stratified by socioeconomic status, with 60 children aged 9-10 years (24 boys, 36 girls), 33 parents (4 male, 29 female) and 10 teachers (4 male, 6 female). Questions for interviews were structured around the PRECEDE stage of the PRECEDE-PROCEDE model and addressed knowledge, attitudes and beliefs towards physical activity, as well as views on barriers to participation. All data were transcribed verbatim. Pen profiles were constructed from the transcripts in a deductive manner using the Youth Physical Activity Promotion Model framework. The profiles represented analysis outcomes via a diagram of key emergent themes.Analyses revealed an understanding of the relationship between physical activity and health, although some children had limited understanding of what constitutes physical activity. Views elicited by children and parents were generally consistent. Fun, enjoyment and social support were important predictors of physical activity participation, though several barriers such as lack of parental support were identified across all group interviews. The perception of family invested time was positively linked to physical activity engagement.Families have a powerful and important role in promoting health-enhancing behaviours. Involvement of parents and the whole family is a strategy that could be significant to increase children's physical activity levels. Addressing various perceived barriers to such behaviours therefore, remains imperative.ISRCTN: ISRCTN03863885.

Project description:Objective: To determine whether psychosocial constructs targeted in an online physical activity intervention for Latinas mediated changes in moderate-to-vigorous physical activity (MVPA). Method: Data were taken from a randomized trial of a web-based MVPA intervention for Latina women age 18-65 (N = 205) based on social cognitive theory and the transtheoretical model. Baseline and 6-month measures included minutes/week of MVPA (ActiGraph GT3X + accelerometers and 7-Day Physical Activity Recall Interview) and theorized mediators (self-efficacy, behavioral processes, cognitive processes, social support, enjoyment). A multiple mediation model adjusting for baseline MVPA was fit using a products of coefficients method, simultaneously testing all hypothesized mediators. Results: MVPA increased more in the intervention group than controls by 50 min/week (self-report) and 31 min/week (accelerometers). For the self-reported MVPA model, there was an intervention effect (a-path coefficient) on self-efficacy (b = 0.43, p < .01), cognitive processes (b = 0.64, p < .01), behavioral processes (b = 0.54, p < .01), and enjoyment (b = 9.91, p = .01). Changes in self-efficacy (b = 24.54, p = .03), social support from friends (b = 2.36, p = .04), and enjoyment (a = 0.74, p = .08) were associated with changes in MVPA (b-path coefficient). However, only changes in self-efficacy (b = 10.49, 95% CI [2.46, 24.54]) and enjoyment (b = 7.30, 95% CI [0.92, 21.78]) mediated the intervention effect on MVPA (ab-path coefficient). For the accelerometer-measured MVPA model, intervention effects were significant for self-efficacy (b = 0.48, p < .01), cognitive processes (b = 0.62, p < .01), and behavioral processes (b = 0.61, p < .01), yet only self-efficacy was associated with changes in MVPA (b = 4.43, p = .03), and mediated intervention effects on MVPA (b = 12.15, 95% CI [11.25, 16.34]). Conclusions: Future MVPA interventions with Latinas should target self-efficacy and enjoyment to maximize efficacy. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
