Food frequency questionnaire results correlate with metabolic control in insulin-treated veterans with type 2 diabetes: the Diabetes Outcomes in Veterans Study

Higher body mass index and lower intake of dairy products predict poor glycaemic control among Type 2 Diabetes patients in Malaysia

This cross-sectional study was designed to determine factors contributing to glyceamic control in order to provide better understanding of diabetes management among Type 2 Diabetes patients. A pre-tested structured questionnaire was used to obtain information on socio-demographic and medical history. As a proxy measure for glycaemic control, glycosylated haemoglobin (HbA1c) was obtained as secondary data from the medical reports. Perceived self-care barrier on diabetes management, diet knowledge and skills, and diet quality were assessed using pretested instruments. With a response rate of 80.3%, 155 subjects were recruited for the study. Mean HbA1c level of the subjects was 9.02 ± 2.25% with more than 70% not able to achieve acceptable level in accordance to WHO recommendation. Diet quality of the subjects was unsatisfactory especially for vegetables, fruits, fish and legumes as well as from the milk and dairy products group. Higher body mass index (BMI), poorer medication compliance, lower diet knowledge and skill scores and lower intake of milk and dairy products contributed significantly on poor glycaemic control. In conclusion, while perceived self-care barriers and diet quality failed to predict HbA1c, good knowledge and skill ability, together with appropriate BMI and adequate intake of dairy products should be emphasized to optimize glycaemic control among type 2 diabetes patients.

Setting Single or Multiple Goals for Diet and Physical Activity Behaviors Improves Cardiovascular Disease Risk Factors in Adults With Type 2 Diabetes

Purpose

The purpose of this study was to evaluate a 4-month telephone-based goal-setting and decision support intervention among adults with type 2 diabetes mellitus (T2DM) and multiple risk factors for cardiovascular disease (CVD).

Methods

A randomized pretest-posttest control group design was employed. Overweight or obese adults aged 40 to 75 years with T2DM and ≥1 additional CVD risk factor were provided with individualized CVD risk information. At baseline and each biweekly telephone call, the multiple-goal group self-selected both diet- and physical activity–related goals, the single goal group set a single goal, and the control group received information about community health resources. Dietary intake was assessed via a food frequency questionnaire, physical activity via questionnaire, and A1C and blood lipids via fasting fingerstick sample. Between-group differences for clinical (ie, A1C, blood pressure, and blood lipids), physical activity, and dietary variables were evaluated using Kruskal-Wallis, Mann-Whitney U, analysis of variance, and t tests.

Results

From pre- to postintervention, the single-goal group demonstrated significant improvement in systolic blood pressure and intake of servings of fruits, vegetables, and refined grains (all P < .05). The multiple-goal group reported significant reduction in percent energy from total, saturated, monounsaturated, and trans fat intake and significant increase in leisure time walking (all P < .05).

Conclusion

A multiple-goal approach over 4 months can improve dietary and physical activity outcomes, while a single-goal approach may facilitate improvement in one behavioral domain. Additional research is needed to evaluate maintenance of the achieved changes.

Depression and adherence to lifestyle changes in type 2 diabetes: a systematic review

PURPOSE

Depression affects millions of people worldwide and is prevalent among those with diabetes. The purpose of this review was to synthesize recent research on depression and adherence to dietary and physical activity recommendations in persons with type 2 diabetes (T2DM).

METHODS

This systematic review is a subanalysis of an NIH-funded model-testing meta-analysis. Thirteen electronic databases were searched using terms: depression, adherence, T2DM, diabetes. Selected studies: were reported in English between 2000 and 2012, focused on adults with T2DM, and measured depression and dietary and/or physical activity adherence.

RESULTS

Twenty-seven studies involving 7266 participants were selected; participants were 54% female and 62 years of age, on average. When reported, depression prevalence in study samples ranged from 4.5% to 74%. Six intervention studies targeted diabetes treatment, with or without depression treatment; no studies focused solely on treating depression. Twenty-one descriptive studies examined relationships between depression and diet/physical activity adherence, finding a negative association. Only 2 of the 6 intervention studies examined this relationship; findings were inconsistent.

CONCLUSION

Depression was associated with lower adherence to diabetes self-care, as evidenced primarily by descriptive studies; results of intervention studies were conflicting. Future research should focus on the effects of treating depression on diabetes health outcomes.

Factors influencing disease self-management among veterans with diabetes and poor glycemic control

SPECIFIC AIM

Although the Department of Veterans Affairs (VA) has made significant organizational changes to improve diabetes care, diabetes self-management has received limited attention. The purpose of this study is to assess factors influencing diabetes self-management among veterans with poorly controlled diabetes.

METHODS

Surveys were mailed to patients with type 2 diabetes and a HbA1c of 8% or greater who attended 1 of 2 VA Medical Centers in Washington State (n = 1,286). Validated survey instruments assessed readiness to change, self-efficacy, provider advice, and diabetes self-care practices.

RESULTS

Our response rate was 56% (n = 717). Most respondents reported appropriate advice from physicians regarding physical activity, nutrition, and glucose monitoring (73%, 92%, and 98%, respectively), but many were not ready to change self-management behaviors. Forty-five percent reported non-adherence to medications, 42% ate a high-fat diet, and only 28% obtained either moderate or vigorous physical activity. The mean self-efficacy score for diabetes self-care was low and half of the sample reported readiness to change nutrition (52%) or physical activity (51%). Individuals with higher self-efficacy scores were more likely to adhere to medications, follow a diabetic meal plan, eat a lower fat diet, have higher levels of physical activity, and monitor their blood sugars (P < .001 for all).

CONCLUSIONS

Although veterans with poor diabetes control receive appropriate medical advice, many were not sufficiently confident or motivated to make and maintain self-management changes. Targeted patient-centered interventions may need to emphasize increasing self-efficacy and readiness to change to further improve VA diabetes outcomes.

Reliability and validity of the DCP among hispanic veterans

The Diabetes Care Profile (DCP) was designed to measure psychosocial factors related to diabetes and its treatment. This study sought to determine the reliability and validity of the DCP in Hispanic veterans with Type 2 diabetes. Hispanic (n=81) and non-Hispanic White (n=238) patients were recruited at three southwestern VA hospitals. Scale reliabilities calculated by Cronbach's coefficient alpha revealed reliabilities ranging from .54 to .97 in Hispanics and .63 to .95 in non-Hispanic Whites. Only one scale, Monitoring Barriers, differed significantly between the two patient groups. Mean values on the DCP scales were consistent within and across ethnicities lending support for construct validity of the DCP in Hispanics. Convergent validity was also supported for DCP scales within the Hispanic patients as evidenced by correlations in expected directions with external measures.

Longitudinal Examination of Homebound Older Adults Who Experience Heightened Food Insufficiency: Effect of Diabetes Status and Implications for Service Provision

PURPOSE

Healthful eating is important for optimal diabetes self-care. However, the level of food sufficiency may influence the degree of adherence to dietary self-care behaviors through the affordability of nutritionally appropriate food. This study examines whether homebound older adults with diabetes were at greater risk for heightened food insufficiency over 1 year, despite regular receipt of home-delivered meals.

DESIGN AND METHODS

This was a longitudinal study of a randomly recruited sample of 268 homebound older adults in the Nutrition and Function Study (NAFS) who regularly received home-delivered meals and completed baseline and 1-year in-home assessments. Based on an economic context model, self-reported data were collected on fundamental and proximate factors, food-sufficiency status, and intervening events. Determinants of heightened food insufficiency were examined with multivariate logistic regression models.

RESULTS

Not only did food-sufficiency status diminish over time in this sample, but it became or remained worse for older adults with diabetes. In addition to diabetes status, heightened food insufficiency was associated with perceived inadequacy of economic resources.

IMPLICATIONS

Health care providers and nutrition programs should attempt to identify high-risk older adults - those who have diabetes and are at risk of food insufficiency - and develop community linkages and strategies that integrate nutrition with diabetes care plans, thus supporting a multidisciplinary, chronic care model to improve diabetes management and outcomes.
