This study examined links among unrealistic optimism, sex, and risk perception of type 2 diabetes onset in college students. Participants included 660 college students who consented to complete a questionnaire. The results showed significant differences between students who perceived that they were at risk for type 2 diabetes onset and those who thought their peers were the ones at risk. A higher prevalence of participants thought their peers were the ones at risk for type 2 diabetes. Women were more likely than men to report a higher risk perception, indicating that their peers were at lower risk for diabetes onset.

Background: There is a lack of a valid and reliable instrument that measures objective and subjective knowledge of evidence-based dietetic practices (EBDP) among registered dietitian nutritionists (RDNs). The present study aimed to develop and assess the validity and reliability of an EBDP Questionnaire (EBDPQ) with objective knowledge items (i.e., quiz items) among RDNs in the USA. Methods: Subscales from four existing evidence-based practice (EBP) instruments were combined and modified for dietetics. Content and face validity and internal consistency were used to assess the full survey. Survey responsiveness and test-retest reliability were evaluated within the objective knowledge subscale. Content experts (n = 11) and nutrition professionals (n = 16) completed validation reviews. Doctoral students enrolled in a research course (n = 12) were used to analyse survey responsiveness. Internal and test-retest relability analyses utilised RDN participants (time point 1, n = 482; time point 2, n = 335). Results: Content validation resulted in a 38-item questionnaire. Average percent agreement among face validity reviewers was 95.1%. Only the prevalidation version of the objective knowledge subscale resulted in significantly higher post-course scores (Mdn = 11.50) compared to the pre-course (Mdn = 9.75, p = 0.05). The validated instrument had excellent internal consistency (Cronbach's α = 0.91); however, the objective knowledge subscale was low (Cronbach's α = 0.41). A good degree of reliability was found between the two time points (intraclass correlation coefficient = 0.71). Conclusions: The EBDPQ demonstrated adequate validity and reliability among RDNs. Future research should assess construct validity, with the responsiveness and objective knowledge subscale requiring additional evaluation through an EBDP course.evidence-based dietetic practice, registered dietitian nutritionist, reliability, validity Key points• Subjective measures may not adequately estimate the knowledge of evidence-based dietetic practices (EBDPs) among dietitians. • Subscales from four evidence-based practice instruments, including both subjective and objective (i.e., quiz items) measures, were adapted for the dietetics practitioner. • This instrument demonstrated adequate validity and reliability among dietitians; however, the objective knowledge subscale was low (Cronbach's

BACKGROUND: Worksite wellness programs have the ability to activate health promotion and stimulate behavior change. OBJECTIVE: To measure longitudinal associations between visits with a Registered Dietitian Nutritionist (RDN), as part of worksite wellness programs, on dietary and lifestyle behavior changes. METHODS: The study sample included 1,123 employees with 77 different worksite wellness programs across the United States from March to December 2017. Hierarchical linear modeling was used to evaluate the associations of RDN visits with behavior changes. RESULTS: The mean BMI at baseline was 33.48, indicating over half of all employees are considered obese. Employees who attended more than one visit showed an increase in whole grain consumption and corresponding weight loss (t-ratio = 2.41, p = 0.02). Age played a significant factor in the rise of systolic blood pressure; employees who attended more visits showed an increase in whole grain consumption and corresponding blood pressure (t-ratio = –2.11, p = 0.04). CONCLUSIONS: RDNs as part of worksite wellness programs, can contribute to improvements in lifestyle behavior changes. These data highlight the need for nutrition intervention at the workplace. Research on nutrition-focused worksite wellness programs is needed to assess the long-term health outcomes related to dietary and lifestyle behavior changes.

Background: African Americans (AAs) living in the “Stroke Belt” region are at elevated risk for cardiovascular diseases (CVDs) including stroke. Our long-term goal is to eliminate this ethnic/regional health disparity by targeting a major modifiable risk factor for stroke, hypertension (HTN). Besides medications, lifestyle interventions are effective in lowering blood pressure (BP), and the “DASH diet has been shown to lower BP, however, in the PREMIER program, DASH with lifestyle modifications was less effective in AAs with regards to BP reduction. We hereby present a PREMIER modified, faith-based, socio-culturally tailored, multi-level HTN control behavioral intervention called HEALS adopted by AA churches. The objective is to determine the efficacy of HEALS on BP and other related outcomes. Methods: Based on Community advisory board (CAB) recommendations, a church selected from a pool of 26 participating churches. Trained church leaders enrolled eligible participants and delivered weekly HEALS sessions for 12 weeks. Target population included church members 25-75 years, with known or newly diagnosed HTN/pre-HTN as per JNC-7 classification. Information was obtained on BP, weight, waist circumference, diets and physical activity. Results: A total of 36 eligible church members were recruited, 32 provided data that was used in this analysis n=32 (89% retention). At baseline, 28 members were known HTN and remaining were newly diagnosed (22%). After the completion of the 12 weeks intervention, the mean reduction in systolic BP (SBP) and diastolic BP (DBP) were 6.72mmHg (p=.0425) and 4 mmHg (p=.0073), respectively. A weight reduction of 1.7 Kg was also significant (p=0.0023). Similarly, diet changes were significant and showed that more than half consumed dark green or other vegetables frequently, while 75% consumed at least one fruit daily or weekly. Lower percentages (44%) reported consumption of 100% fruit juices or cooked beans regularly. Study is currently in its 6-month maintenance phase. Conclusion: Under controlled settings, community-based interventions can be successful in producing desirable outcomes and in maintaining high retention rates. HEALS intervention can be used as a model of efficacious program in church settings.
