New directions for diabetes prevention and management in behavioral medicine.

Accelerating diabetes rates have resulted in a global public health epidemic. Lifestyle change is a cornerstone of care, yet regimen demands may result in adherence difficulties. Distress, depression, and other psychosocial concerns are higher in those with diabetes. While interventions, such as the Diabetes Prevention Program appear to be effective, further research is needed to support the translation of interventions to prevent diabetes. Studies assessing optimal approaches to promoting effective decision making, coping and adherence are needed. More information is needed to evaluate the influence and potential of emerging technologies on intervention delivery and quality of life in children and adults with diabetes. Theoretically informed, interdisciplinary studies that consider ecological models are needed to develop a roadmap for policies and diabetes management recommendations. Reduction of diabetes-related health disparities is a critical area for future studies. Behavioral medicine scientists and practitioners are poised to address these and other proposed future research directions to advance diabetes prevention and management.

Associations between sleep, physical activity, and emotional well-being in emerging young adults: Implications for college wellness program development.

Objectives: To examine sleep, physical activity, and their joint associations with physical functioning and affect. Participants: 108 undergraduates completed questionnaires assessing sleep, activity levels, emotional well-being and physical health markers. Results: Participants reported poor sleep quality, suboptimal sleep duration, and inconsistent physical activity. Poor sleep quality was associated with higher fatigue for both active and insufficiently active groups (F = 9.94, p = .002). There was a significant interaction between activity level and sleep duration on negative affect (F = 7.14, p = .009). Students who reported insufficient physical activity and less than 6 hours of sleep had the highest negative affect. Conclusions: Poor sleep quality was associated with increased fatigue. Students who inconsistently exercise and have suboptimal sleep may be at greater risk for affective difficulties. We recommend that college wellness interventions jointly target health behaviors and affect to optimize prevention efforts aimed at addressing physical and mental health outcomes, including depression and chronic illness.

Appraising quantitative research in health education: guidelines for public health educators.

Many practicing health educators do not feel they possess the skills necessary to critically appraise quantitative research. This publication is designed to help provide practicing health educators with basic tools helpful to facilitate a better understanding of quantitative research. This article describes the major components- title, introduction, methods, analyses, results, and discussion sections-of quantitative research. Readers will be introduced to information on the various types of study designs and seven key questions health educators can use to facilitate the appraisal process. On reading, health educators will be in a better position to determine whether research studies are well designed and executed.

Understanding systems and rhythms for minority recruitment in intervention research.

We describe one approach for recruitment and retention of minority individuals in intervention research using a systematic environmental perspective based on Bronfenbrenner's ecological systems (BES) model and the construct of temporality. An exemplar in a physical activity intervention study with low-income and primarily African American women is presented. The exemplar illustrates application of BES and temporality to enhance recruitment and retention in research focused on understanding and accommodating environmental influences. Using this theory based approach resulted in successful recruitment and a high level of participant retention.

An examination of the moderating effect of treatment with anti-depressants on the association of heart disease with depression in males with type 2 diabetes attending a Veterans Affairs Medical Center.

OBJECTIVE: To examine the association of heart disease with depression and the impact of treatment with anti-depressants on this association in older males with type 2 diabetes. RESEARCH DESIGN AND METHODS: In this cross-sectional study, data were collected from the electronic medical record system of the Veterans Affairs Medical Center (VAMC) in a large mid-western city in the United States. Subjects were 8185 males older than 40, with a history of type 2 diabetes, who had visited the VAMC within the previous 6 years. Odds ratios were used to measure bivariate associations; multivariate logistic regression was used to adjust for potential confounding factors. RESULTS: After adjustments for confounding variables, significant associations were found between depression and any adverse heart event (OR=1.34, p=0.001), coronary artery disease (OR=1.23, p=0.039), myocardial infarction (MI; OR=1.77, p<0.001), and angioplasty (OR=1.36, p=0.034). Examination of the interaction between depression and anti-depressant prescription status indicated that, except for MI, these associations were no longer significant among those who had been prescribed anti-depressants, but remained significant and were increased in magnitude among those who had not been prescribed anti-depressants. CONCLUSIONS: These findings support the premise that co-morbid depression in diabetics is associated with the occurrence of adverse heart events, and further suggest that treatment of depression with anti-depressants moderates this association.

An environmental intervention aimed at increasing physical activity levels in low-income women.

BACKGROUND: Regular physical activity is a health promotion and disease prevention behavior. Of all demographic groups, low-income women report the lowest levels of physical activity. RESEARCH OBJECTIVE: The purpose of this study was to test an intervention aimed at reducing community environmental barriers to physical activity in low-income women. METHODS: The research design was mixed methodology: (1) quantitative (quasi-experimental, pretest-posttest, cohort design in which no treatment partitioning was possible) and (2) qualitative (focus groups). The setting was a church-sponsored community center centrally located in a low-income urban neighborhood. The comparison group was recruited first followed by the intervention group to control for setting. The sample consisted of 104 women (comparison group, n = 53; intervention group, n = 51) between the ages of 18 and 63 years who were residents of neighborhoods served by the community center. RESULTS: No between-group differences were found for physical activity behavior. Significant between-group differences in cholesterol (P = .007) and perception of physical activity (P = .033) were observed. Significant intervention group increases from pretest to posttest were found related to advanced registered nurse practitioner support, friend support, and more positive physical activity environment at the community center. Qualitative data supported and enriched the quantitative data. CONCLUSIONS: Physical activity levels were not significantly different between the groups. In a sample of low-income women who have multiple barriers, improving attitudes, expanding their knowledge of community resources, and providing physical activity opportunities in their neighborhoods are important intermediate steps toward initiation and maintenance of regular physical activity.

Diabetes and driving mishaps: frequency and correlations from a multinational survey.

OBJECTIVE: The intensive treatment of diabetes to achieve strict glycemic control is a common clinical goal, but it is associated with an increased incidence of hypoglycemia. Becoming hypoglycemic while driving is a hazardous condition and may lead to a greater incidence of driving mishaps. This study investigated whether diabetes is associated with increased risk of driving mishaps and correlates of such a relationship. RESEARCH DESIGN AND METHODS: During routine visits to diabetes specialty clinics in seven U.S. and four European cities, consecutive adults with type 1 diabetes, type 2 diabetes, and nondiabetic spouse control subjects (n = 341, 332, and 363, respectively) completed an anonymous questionnaire concerning diabetes and driving. RESULTS: Type 1 diabetic drivers reported significantly more crashes, moving violations, episodes of hypoglycemic stupor, required assistance, and mild hypoglycemia while driving as compared with type 2 diabetic drivers or spouse control subjects (P < 0.01-0.001). Type 2 diabetic drivers had driving mishap rates similar to nondiabetic spouses, and the use of insulin or oral agents for treatment had no effect on the occurrence of driving mishaps. Crashes among type 1 diabetic drivers were associated with more frequent episodes of hypoglycemic stupor while driving, less frequent blood glucose monitoring before driving, and the use of insulin injection therapy as compared with pump therapy. One-half of the type 1 diabetic drivers and three-quarters of the type 2 diabetic drivers had never discussed hypoglycemia and driving with their physicians. CONCLUSIONS: Type 1 diabetic drivers are at increased risk for driving mishaps, but type 2 diabetic drivers, even on insulin, appear not to be at a higher risk than nondiabetic individuals. Clinical and treatment factors appear to increase risk, e.g., more frequent hypoglycemia while driving, method of insulin delivery, and infrequent self-testing before driving. Physicians are encouraged to talk to their type 1 diabetic patients about hypoglycemia and driving.

Diet self-management and readiness to change in underserved adults with type 2 diabetes.

AIM: Dietary assessment in diabetes may be enhanced by considering patient-centered perspectives and barriers to change within IDF guidelines. Consideration of readiness to change (RTC) diet in underserved samples may guide future interventions in high risk populations. This study assesses the utility of a rapid assessment of RTC diet in a medically underserved sample. METHOD: Participants were 253 Black (43.7%) and White (55.1%) American adults with type 2 diabetes [M age=57.93 (11.52); 60.5% female; 19% below the US poverty threshold]. Participants were recruited at medical clinics and completed validated self-report measures assessing diabetes knowledge, self-efficacy and dietary behaviors and barriers by RTC. RESULTS: Stage-based comparisons identified significant differences in diabetes and dietary domains: participants in the Action stage endorsed fewer behavioral dietary barriers (p<.001), more frequent dietary problem-solving (p<.001), and greater diabetes self-efficacy (p<.001) than participants in the Contemplation and Preparation stages. Women were more likely to be in the Preparation stage and beyond (p<.05). CONCLUSIONS: Findings highlight the clinical utility of a brief measure of RTC in understanding patient perspectives toward dietary behaviors in a medically underserved sample. The impact of gender on RTC diet warrants further exploration.

Patient perspectives on self-monitoring of blood glucose: perceived recommendations, behaviors and barriers in a clinic sample of adults with type 2 diabetes.

BACKGROUND: Patient-centered perspectives on self-monitoring of blood glucose (SBMG) were assessed in adults with type 2 diabetes using a self-regulation conceptual framework. METHODS: Participants (N = 589; 53 % female) were adults with type 2 diabetes who were recruited during routine appointments at a diabetes outpatient clinic in the Southeastern/lower Midwestern region of the United States. RESULTS: Participant's had varying perceptions regarding provider recommendations for SMBG (responder n = 380). Personal blood glucose testing patterns were also varied and reports frequently omitted (responder n = 296). Respondent's most frequent personal pattern was to test "occasionally, as needed," which did not differ by insulin use status, gender or age. In those not prescribed insulin, HbA1c reflected better control in those testing at least once per week (p = .040) or with a blood glucose goal (p = .018). 30.9 % endorsed at least monthly perceived encounters with SMBG barriers, with higher reports by women (p = .005) and younger (p = .006) participants. Poorer glycemic control was observed for participants with more frequently reported scheduling (p = .025, .041) and discouragement (p = .003) barriers. CONCLUSIONS: Findings suggest that many may experience difficulty integrating SMBG into their lives and are unsure of recommendations and appropriate function. Research is needed to promote best practice recommendations for SMBG.

Self-Reported Physical Activity in Medically Underserved Adults With Type 2 Diabetes in Clinical and Community Settings.

BACKGROUND: This study assessed physical activity (PA) in community dwelling adults with Type 2 diabetes, using multiple instruments reflecting internationally normed PA and diabetes-specific self-care behaviors. METHODS: Two hundred and fifty-three Black (44.8%) and White (55.2%) Americans [mean age = 57.93; 39.5% male] recruited at low-income clinic and community health settings. Participants completed validated PA self-report measures developed for international comparisons (International Physical Activity Questionnaire Short Form), characterization of diabetes self-care (Summary of Diabetes Self-Care Activities Measure; SDSCA) and exercise-related domains including provider recommendations and PA behaviors and barriers (Personal Diabetes Questionnaire; PDQ). RESULTS: Self-reported PA and PA correlates differed by instrument. BMI was negatively correlated with PA level assessed by the PDQ in both genders, and assessed with SDSCA activity items in females. PA levels were low, comparable to previous research with community and diabetes samples. Pain was the most frequently reported barrier; females reported more frequent PA barriers overall. CONCLUSIONS: When using self-report PA measures for PA evaluation of adults with diabetes in clinical settings, it is critical to consider population and setting in selecting appropriate tools. PA barriers may be an important consideration when interpreting PA levels and developing interventions. Recommendations for incorporating these measures in clinical and research settings are discussed.

Talking to patients about aerobic exercise for disease prevention: an educational exercise for medical students.

Numerous data demonstrate the importance of physical activity in reducing obesity and cardiovascular mortality and morbidity. Research demonstrates the beneficial impact of physician counseling on health promoting behaviors. Unfortunately, few physicians or medical students receive formal training in exercise counseling. We describe an educational activity used to provide medical students with the tools needed to begin to engage patients in activity counseling.

Depression may mediate the relationship between sense of coherence and quality of life in lung cancer patients.

Lung cancer patients generally experience high levels of physical and psychological distress and decreased quality of life (QOL). Sense of coherence (SOC) has been conceptualized as a personality orientation reflecting the degree to which an individual perceives their world as comprehensible, manageable and meaningful. The present study investigated the associations of SOC with QOL in lung cancer. It also examined potential psychological mediators by which SOC may exert its influences on QOL. Fifty-six participants with non-small cell lung cancer were administered self-report assessments of SOC, QOL and psychological distress. Results revealed that SOC was positively associated with QOL and this relationship may be mediated by depressive symptoms. The current study supports the notion that SOC may be a protective factor with regard to psychological adjustment and QOL in cancer survivors.

Assessing the value of the diabetes educator.

PURPOSE: The purpose of this study was to evaluate the effectiveness of diabetes self-management education or training provided by diabetes educators in reducing complications and improving quality of life. METHODS: Commercial and Medicare payer-derived claims data were used to assess the relationship between DSME/T and cost. Unlike the prior study that examined diabetes education provided by all professionals, the current study focused on the value of interventions performed as part of formal accredited/recognized diabetes education programs provided by diabetes educators only. Specifically, the current study focused on diabetes education delivered in diabetes self-management training programs based on 2 codes (G0108 and G0109). RESULTS: Results of the study provide insights into the differences in trends between participants and nonparticipants in DSMT. People with diabetes who had DSMT encounters provided by diabetes educators in accredited/recognized programs are likely to show lower cost patterns when compared with a control group of people with diabetes without DSMT encounters. People with diabetes who have multiple episodes of DSMT are more likely to receive care in accordance with recommended guidelines and to comply with diabetes-related prescription regimens, resulting in lower costs and utilization trends. Conclusions and Policy Implications The collaboration between diabetes educators and patients continues to demonstrate positive clinical quality outcomes and cost savings. This analysis shows that repeated DSMT encounters over time result in a dose-response effect on positive outcomes.

Development and validation of The Personal Diabetes Questionnaire (PDQ): a measure of diabetes self-care behaviors, perceptions and barriers.

AIM: To develop and evaluate the validity and reliability of The Personal Diabetes Questionnaire (PDQ), a brief, yet comprehensive measure of diabetes self-care behaviors, perceptions and barriers. To examine individual items to provide descriptive and normative information and provide data on scale reliability and associations between PDQ scales and concurrently assessed HBA(1c) and BMI. METHOD: Items were written to address nutritional management, medication utilization, blood glucose monitoring, and physical activity. The initial instrument was reviewed by multidisciplinary diabetes care providers and items subsequently revised until the measure provided complete coverage of the diabetes care domains using as few items as possible. The scoring scheme was generated rationally. Subjects were 790 adults (205 with type 1 and 585 with type 2 diabetes) who completed the PDQ while waiting for clinic appointments. RESULTS: Item completion rates were high, with few items skipped by participants. Subscales demonstrated good internal consistency (Cronbach α=.650-.834) and demonstrated significant associations with BMI (p ≤.001) and HbA(1c) (p ≤.001). CONCLUSIONS: The PDQ is a useful measure of diabetes self-care behaviors and related perceptions and barriers that is reliable and valid and feasible to administer in a clinic setting. This measure may be used to obtain data for assessing diabetes self-management and barriers and to guide patient care.

Monitoring in diabetes self-management: issues and recommendations for improvement.

The American Association of Diabetes Educators hosted a Monitoring Symposium during which 18 invited participants considered pre-set questions regarding how diabetes education can more effectively address barriers to monitoring for people with diabetes and related conditions. This report provides a summary of the moderated discussion and highlights the key points that apply to diabetes educators and other providers involved with diabetes care. The participating thought leaders reviewed findings from published literature and participated in a moderated discussion with the aim of providing practical advice for health care practitioners regarding monitoring for people with diabetes so that the overall health of this population can be enhanced. The discussants also defined monitoring for diabetes as including that done by the clinician or laboratory, as well as self-monitoring. The discussion was distilled into key points that apply to diabetes educators and other providers involved with diabetes care. Participants developed specific recommendations for a self-monitoring behavior and monitoring framework. People with diabetes benefit from instruction and guidance about self-monitoring and decision making that is based on monitored results and informed interactions with providers. Importantly, collaboration among the entire diabetes care community is needed to ensure that monitoring is performed and utilized to its fullest advantage. Going forward, it will be critical to mitigate barriers to diabetes self-management and training and to identify linkages and partnerships to address barriers to self-monitoring.

Mindfulness and acceptance are associated with exercise maintenance in YMCA exercisers.

Although most U.S. adults have initiated an exercise program at some time, only a fraction are able to maintain consistent exercise. Instead, research suggests that intermittent exercise is commonplace among U.S. adults, underscoring the importance of identifying factors associated with consistent exercise at a level that promotes health and long-term maintenance of this activity. We proposed a theoretical model in which mindfulness and acceptance may promote exercise initiation and maintenance. Mindfulness, acceptance, and suppression were examined as a function of exercise status in 266 YMCA exercisers. Those who were successful at maintaining exercise tended to score higher on measures of mindfulness and acceptance, and lower on measures of suppression. Findings are discussed in light of our proposed theoretical model in which exercisers having greater mindfulness and acceptance are less reactive; responding with more balanced appraisals to threats to their exercise regimen which in turn promotes increased exercise maintenance. Future studies should utilize longitudinal design to examine causal relationships between variables.

Exercise slips in high-risk situations and activity patterns in long-term exercisers: an application of the relapse prevention model.

BACKGROUND: Key factors in successful long-term exercise maintenance are not well understood. The Relapse Prevention Model (RPM) may provide a framework for this process. PURPOSE: The purpose of this study was to examine the relationships among characteristics of exercise high-risk situations, components of the RPM relevant to exercise slips, and follow-up exercise outcomes in long-term community exercisers. METHODS: We obtained long-term exercisers' (N=65) open-ended responses to high-risk situations and ratings of obstacle self-efficacy, guilt, and perceived control. High-risk situation characteristics, cognitive and behavioral coping strategies, and exercise outcomes were examined. RESULTS: High-risk situation characteristics included bad weather, inconvenient time of day, being alone, negative emotions, and fatigue. Being alone was associated with lower incidence of exercise slip. Positive cognitive coping strategies were most commonly employed and were associated with positive exercise outcome for both women and men. Guilt and perceived control regarding the high-risk situation were associated with exercise outcomes at follow-up, but only among the men (n=28). CONCLUSIONS: Findings confirm and extend previous work in the application of the RPM in examining exercise slips and relapse. Measurement issues and integration approaches from the study of relapse in addiction research are discussed.

Development and Evaluation of a Nutrition and Physical Activity Counseling Module for First-Year Medical Students.

INTRODUCTION: Few Americans follow recommendations regarding nutrition or physical activity, and few physicians provide nutritional counseling (NC) or physical activity counseling (PAC) to patients. Clinical, systems-based, and institutional barriers to teaching and providing NC and PAC exist, but theoretical models of behavior change and principles of adult learning theory (ALT) can enable medical educators to overcome these barriers. METHODS: We developed an educational intervention consisting of interactive lectures and two standardized patient experiences to provide first-year medical students with practical experience in PAC and NC. Students completed pre and post educational assessments of attitudes, knowledge, and self-efficacy with the counseling techniques. RESULTS: Knowledge scores increased from 6.1 to 8.5 (p<.001) on a 13-item test. Self-confidence scores for NC increased from 45 to 78 (p<.001), and self-confidence scores for PAC increased from 51 to 82 (p<.001). While overall attitudes regarding the necessity and utility of counseling with specific disease states were not different pre/ post test (necessity pre/post 6.3 to 6.2 p= .71; utility pre/post 5.8 to 5.7 p=.88), necessity and utility scores for disease states treated primarily with counseling were different compared to disease states students perceive to be primarily pharmacologically treated (counseling vs. pharmacological necessity 5.9 vs. 6.6 p<.001; utility 5.4 vs. 6.1 p<.001). CONCLUSION: An educational intervention based on theoretical models of behavior change and ALT can increase knowledge and self confidence scores regarding counseling for NC and PAC.
