ABSTRACT Background: Prediabetes is a precursor condition to type 2 diabetes mellitus. Previous research and clinical trials have shown that the onset of type 2 diabetes could be delayed or prevented through structured life style modifications such as dietary changes, modest weight loss and moderate-intensity exercise. This study examines U.S adults of different ethnicities that include non-Hispanic white, non-Hispanic black and Mexican Americans and whether their awareness of diabetes risk is associated with their participation in diabetes risk reduction behavior, a combination of physical activity, weight control and fat/calories intake. Methods: The 2007-2008 National Health and Nutrition Examination Survey, NHANES, was used to conduct a cross-sectional study of 4083 U.S. adults who were 20 years old and above and were aware of their diabetes risk. The association between the awareness of one’s diabetes risk and the adoption of diabetes risk reduction behavior were examined in present of other risk factors such as age, gender, ethnicity, education, annual family income, BMI, hypertension, mean systolic blood pressure, mean diastolic blood pressure, total cholesterol, LDL, HDL and triglyceride levels. Males and females were examined separately for all analyses performed. Cross tabulation was conducted and p-values were calculated by the Pearson’s chi-square test for the categorical variables which include gender, ethnicity, education, annual family income, adiposity and hypertension. One Way ANOVA and Tukey post hoc tests were conducted for the continuous variables which include age, mean systolic blood pressure, mean diastolic blood pressure, total cholesterol, LDL, HDL and triglyceride levels. Univariate and multivariate analyses were performed to determine the association between the main independent variable, awareness of one’s diabetes risk, and the dependent variable, adoption of diabetes risk reduction behavior, controlling for other risk factors. A p-value of <0.05 and 95% confidence intervals were used to determine statistical significance throughout all analyses performed. Results: After controlling for age, gender, race, education, annual family income, BMI, hypertension, mean systolic blood pressure, mean diastolic blood pressure, total cholesterol, LDL, HDL, and triglycerides, results from the multivariate analysis showed that subjects who were aware of their diabetes risk were more likely to adopt diabetes risk reduction behavior (OR= 1,734, 95 % CI=1.217-2.470). Females and non-Hispanic blacks, who were aware of their diabetes risk, were also more likely to adopt diabetes risk reduction behavior compared to males, non-Hispanic whites and Mexican Americans. An increase in the levels of education, annual family income and BMI was also associated with the adoption of diabetes risk reduction behavior. Stratification according to gender and ethnicity, showed that Mexican American males and females were more likely to engage in diabetes risk reduction behavior compared to non-Hispanic whites and non-Hispanic blacks (Mexican American males: OR: 2.496, CI: 0.792-7.868; Mexican American females: OR: 2.830, CI: 0.917-8.736). Conclusion: This study provides useful insights for health care providers and public health professionals who are developing health promotion and prevention interventions to address pre diabetes before it develops into type 2 diabetes. This study also allows the development of tailored interventions for specific genders and ethnic groups that are at risk. Results of this study indicate that Mexican Americans and females (in general) are more likely to adopt diabetes risk reduction behavior. Therefore, physicians and health care providers should develop culturally, linguistically and gender- specific education materials and programs for this particular gender and ethnic group. This in turn, may reduce the overall increasing prevalence of diabetes, reduce racial and gender disparities and may have a positive impact on the overall health of the U.S. population.

Type 2 diabetes (T2DM) is a growing concern worldwide, particularly among Aboriginal Canadians. Diet has been associated with diabetes risk, and dietary pattern analysis (DPA) provides a method in which whole dietary patterns may be explored in relation to disease. Factor analysis (FA) and reduced rank regression (RRR) of data from the Sandy Lake Health and Diabetes Project identified patterns associated with incident T2DM at follow-up. A RRR-derived pattern characterized by tea, hot cereal, and peas, and low intake of high-sugar foods and beef was positively associated with diabetes; however, the relationship was attenuated with adjustment for age and other covariates. A FA-derived pattern characterized by processed foods was positively associated with incident T2DM in a multivariate model (OR=1.38; CIs: 1.02, 1.86 per unit), suggesting intake of processed foods may predict T2DM risk.

There is growing interest in the potential role of omega-3/fibre-rich seeds in attenuating obesity and other cardiovascular disease (CVD) risk factors in individuals with type 2 diabetes mellitus (T2DM). Preliminary data suggests that consumption of white Salvia hispanica L. (Salba&reg;) seeds prolongs satiety and may aid weight loss. This randomized, double-blind, parallel study assessed the efficacy and safety of Salvia hispanica in overweight/obese individuals with T2DM on weight, body composition, glycemic control and other CVD risk factors. Fifty-eight participants consumed a hypocaloric diet including Salvia hispanica or an energy-and-fibre-matched control over 24 weeks. Greater reductions in weight, waist circumference and inflammation occurred in the Salvia hispanica group versus control. There were no significant between-group differences in safety parameters, glycemic control or other CVD risk factors. Salvia hispanica seeds may support weight loss in overweight/obese individuals with T2DM. Further research is needed to determine whether these effects are maintained.

Background and aims: The overall aim of this thesis was to increase knowledge regarding the occurrence of childhood onset T1D and T2D in Sweden and in relation to that describe and elucidate important aspects on two grave complications to diabetes; end-stage renal disease (ESRD) and mortality. The two first studies included in this thesis aimed to describe and analyze the cumulative incidence of childhood onset T1D in Sweden and to assess the occurrence of undetected T2D in Swedish children. The aim with the third study was to describe the cumulative incidence of ESRD, and to analyze how ESRD risk differs with age at-onset and sex. The aim of the fourth study was to show how parental socioeconomic status (SES) affects all cause mortality in Swedish patients with childhood onset T1D. Study populations: The foundation for the studies on T1D was data from the Swedish Childhood Diabetes Registry (SCDR). When studying ESRD we also included adult onset T1D cases from the Diabetes Incidence Study in Sweden (DISS). The study on T2D was a population-based screening study where BMI was measured in 5528 school-children and hemoglobin A1c was measured in children with overweight according to international age and sex specific BMI cut-offs. To study ESRD and mortality, we linked the SCDR to various nationwide registers containing individual information on SES, mortality and ESRD. Results: The incidence rates of childhood onset T1D has continued to increase in Sweden 1977–2007. Age- and sex-specific incidence rates varied from 21.6 (95% CI 19.4–23.9) during 1978–1980 to 43.9 (95% CI 40.7– 47.3) during 2005–2007. Cumulative incidence by birth-cohorts has shifted to a younger age at-onset over the first 22 years of incidence registration. From the year 2000 there was a significant reverse in this trend (p&lt;0.01). In contrast to the increase of T1D, we found no evidence of undetected T2D among Swedish school children. Despite a relatively high incidence in T1D in Sweden there is low cumulative incidence of ESRD, 3.3% at maximum 30 years of duration. We found difference between the sexes regarding long-term risk of developing ESRD that was dependent on the age at onset of T1D. When analyzing how socioeconomic status affects mortality in different age at death groups, we found that having parents that received income support increased mortality up to three times in those who died after 18 years of age. Conclusion: The incidence of childhood onset T1D continued to increase in Sweden 1978-2007. Between the years 1978-1999 there was a shift to a younger age at-onset, but from the year 2000 there is a change in this shift indicating a possible trend break. The prevalence of T2D among Swedish children up to 12 years of age is probably very low. There is still a low cumulative incidence of T1D associated ESRD in Sweden. The risk of developing ESRD depends on age at-onset of T1D, and there is a clear difference in risk between men and woman. Excess mortality among subjects with childhood onset T1D still exists, and low parental socioeconomic status additionally increased mortality in this group.

Background: Physical activity (PA) is an important component of type 2 diabetes management, yet the amount and type of PA support provided by different types of health care providers (HCPs) is largely unknown. Purpose: This study identified differences in the amount and type of PA supports provided by HCPs, and determined whether HCPs use the Canadian Diabetes Association (CDA) PA guidelines or Canada’s Physical Activity Guide (CPAG) in practice. Methods: Eight of 14 Winnipeg Regional Health Authority primary care clinics specializing in diabetes education agreed to participate in the study. In-person interviews were conducted with health care providers (n=48) and patients with type 2 diabetes (n=26). HCPs were given a total PA support score based on scores in three subcategories behaviour change support (BC), assessment/prescription support (AP) and information/referral/community resources support (IRCR), as reported by HCPs themselves and patients. Results: There was no difference in PA support between the 3 HCP types, but there was a significant difference between HCP report and patient report of PA support. Just over one half of HCPs report using the CDA guidelines unprompted or prompted. Conclusions: HCPs recognize the importance of PA in type 2 diabetes management, but implementing strategies to increase certain types of PA support and facilitate understanding between HCPs and patients would allow for optimal PA counseling in primary care.

Objectives: The incidence of type 2 diabetes mellitus (DM2) is on the rise worldwide. The primary objective was to determine the prevalence of nutrient inadequacy and excessiveness in persons with DM2 with and without diabetic peripheral neuropathy (DPN). Study Design: A validated semi-quantitative food frequency questionnaire was used to determine the prevalence of inadequacy of nutrients with an estimated average requirement; the mean intake of nutrients with an adequate intake; and the proportion of persons not meeting the recommendations for the acceptable macronutrient distribution range (AMDR). Results: Differences were observed in the prevalence of inadequacy of vitamin A and the proportion of persons not meeting the AMDR for total fat, linoleic acid and carbohydrate. Conclusion: The aforementioned nutrients may have a significant role in the progression/development of DPN and should be studied in further detail. We recommend a balanced diet and use of a multi-vitamin for persons with DM2.
