Diet Quality Outcomes of a Cooperative Extension Diabetes Prevention Program.

OBJECTIVE: The effectiveness of the National Diabetes Prevention Program (DPP) in improving diet quality (DQ) in community settings is largely unknown. This study aimed to evaluate the DQ changes of Extension DPP participants. METHODS: A single-group, repeated-measures design was used to evaluate an Extension-implemented DPP using the PreventT2 curriculum. Participants were overweight adults with or at high risk for prediabetes (n = 88). Weight and DQ (Healthy Eating Index-2015, Dietary Screener Questionnaire) were evaluated using mixed-effects regression. RESULTS: There was no change in the Healthy Eating Index-2015 total score. Predicted fiber, fruit, and vegetable intake increased (P < 0.05) but remained below recommendations. CONCLUSIONS AND IMPLICATIONS: Clinically meaningful DQ changes of Extension DPP participants were limited. The effect of the DPP on DQ in Extension and other implementation settings should be evaluated through randomized controlled trials. Diabetes Prevention Program curriculum revisions that include more specific dietary goals and educational tools may promote greater DQ changes in DPP participants.

Depressive symptoms, but not moderate-to-vigorous physical activity, impacts sexual well-being and menopause-specific quality of life in middle-aged women.

Inadequate physical activity (PA), unhealthy weight status, prevalence of chronic conditions, and psychosocial distress are common in middle-aged women and are linked to reductions in well-being and quality of life. However, their potential interactive effects, specifically on sexual well-being and menopause-specific quality of life (MENQOL), have not been well characterized in postmenopausal women. PURPOSE: To determine if moderate-to-vigorous physical activity (MVPA) and adiposity (%Fat) influence sexual well-being and MENQOL outcomes, controlling for health status (chronic conditions; medications) and psychosocial well-being (depressive symptoms; perceived stress), in postmenopausal women. Postmenopausal women (n = 68, 58.6 ± 3.4 yr, 80.9 percent married/partnered, 51.5 percent overweight/obese, nonsmoking) were recruited through e-mail advertisements and flyers placed throughout the community. Participants were scheduled for two laboratory visits 7-10 days apart where they were objectively assessed for MVPA with accelerometers (in the interim), adiposity via dual-energy X-ray absorptiometry (DXA), and self-report questionnaires to determine health status, depressive symptoms, perceived stress, sexual well-being, and MENQOL. Lower MVPA and higher %Fat were associated with lower physical domain MENQOL (both r = .27, p < .05); health status and psychosocial well-being were not associated (all p > .05). Hierarchical regression analyses revealed 1) greater number of chronic conditions and medications, and depressive symptoms scores predicted less favorable sexual well-being, independent of MVPA and %Fat (standardized ß range =.22-.56, all p < .05), 2) depression was most consistently associated with MENQOL (models p ≤ .001), and 3) greater adiposity augmented the negative influence of depression on the physical domain of MENQOL (ß = .40. p = .002). CONCLUSIONS: PA may influence sexual well-being and MENQOL indirectly through positive impacts on adiposity, chronic conditions, and depressive symptoms in middle-aged postmenopausal women, a sector of the population often afflicted with compromised sexual well-being.

Implementation of the Diabetes Prevention Program in Georgia Cooperative Extension According to RE-AIM and the Consolidated Framework for Implementation Research.

Increased dissemination of the CDC's Diabetes Prevention Program (DPP) is imperative to reduce type 2 diabetes. Due to its nationwide reach and mission to improve health, Cooperative Extension (Extension) is poised to be a sustainable DPP delivery system. However, research evaluating DPP implementation in Extension remains scant. Extension professionals delivered the DPP in a single-arm hybrid type II effectiveness-implementation study. Semi-structured interviews with Extension professionals were conducted at three time points. The Consolidated Framework for Implementation Research (CFIR) guided interview coding and analysis. Constructs were rated for magnitude and valence and evaluated as facilitators or barriers of RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) outcomes. The program reached 119 participants, was adopted by 92% (n = 12/13) of trained Extension professionals and was implemented according to CDC standards: all programs exceeded the minimum 22-session requirement (26 ± 2 sessions). The program was effective in achieving weight loss (5.0 ± 5.2%) and physical activity (179 ± 122 min/week) goals. At post-intervention, eight professionals (67%) had begun or planned to maintain the intervention within the next 6 months. Several facilitators were identified, including Extension leadership structure, organizational compatibility, and technical assistance calls. Limited time to recruit participants was the primary barrier. Positive RE-AIM outcomes, facilitated by contextual factors, indicate Extension is an effective and sustainable DPP delivery system. Extension and other DPP implementers should plan strategies that promote communication, the program's evidence-base, recruitment time, and resource access. Researchers should explore DPP implementation in real-world settings to determine overall and setting-specific best practices, promote intervention uptake, and reduce diabetes.

Differences in physical activity and perceived benefits and barriers to physical activity between LGBTQ + and non-LGBTQ + college students.

ObjectiveTo compare physical activity (PA) behaviors and perceived benefits and barriers among lesbian, gay, bisexual, transgender, and queer (LGBTQ+) and non-LGBTQ + college students. Participants: Participants were 406 college students. Methods: Surveys assessed PA behaviors and perceptions of PA among college students. Multivariate ANOVA assessed differences in PA behaviors and perceptions of PA. Results: LGBTQ + students (n = 71) engaged in 17% less aerobic PA and 42% less resistance training than their counterparts (n = 335; both p < .05). LGBTQ + students reported 6.5% lower total Exercise Benefits and Barriers Scale scores and 13.3% higher Barriers Scale scores (both p < .05). Conclusions: LGBTQ + college students are at higher risk of not meeting PA guidelines than non-LGBTQ + students. More perceived barriers and fewer perceived benefits to PA may contribute to this disparity. Identification of LGBTQ+-specific barriers to PA among college students is needed to inform programming to increase PA among this at-risk community.

Physical activity and perceived benefits, but not barriers, to exercise differ by sex and school year among college students.

Objective: To assess whether sex or school year influence physical activity and exercise (PA/EX) behaviors and perceived benefits and barriers of PA/EX among college students. Participants: Participants were 862 (78% female; 20.1 ± 1.4 years) college students. Methods: The International Physical Activity Questionnaire, Exercise Benefits and Barriers Scale, and resistance training (RT) questions were completed online. Results: Factorial ANOVA (sex x year) determined no significant interaction effects of sex and school year in behaviors or perceived benefits and barriers (all p > .05). Males reported higher levels of PA/EX and RT than females (p < .05) with no differences by school year (p = .34). Benefits Scale scores and some of its subscales were higher for males and first-year students compared to females and third- and fourth-year students (all p < .05). Conclusion: PA/EX promotion programs may need to be tailored differently based on sex and school year.
