Abstract
The aim of this study was to identify spatial-temporal clusters of high and low diabetes-related mortality from 1990 to 2012 in Argentina. This was a spatial-temporal retrospective ecological study in the population older than 34 years living in Argentina, according to sex, from 1990 to 2012. The spatial units of analysis consisted of the country's departments (subdivisions of the provinces) plus the Autonomous City of Buenos Aires. Spatial-temporal exploration technique was used to detect clusters with high and low mortality. Areas with high mortality from diabetes mellitus were found in the Central-West of the country, and areas with low mortality were found in the coastal region of the province of Buenos Aires and Patagonia. Clusters with high mortality occupied a period from 1995 to 2008; clusters with low mortality shifted towards the years 2002 to 2012. The recent drop in mortality from diabetes was not geographically homogeneous, but displayed a marked decrease in the eastern area of the Province of Buenos Aires and the Autonomous City of Buenos Aires.

Abstract
PURPOSE The purpose of this study was to identify predictors of disease-specific knowledge and patient satisfaction among adult Costa Ricans with type 2 diabetes. Knowledge differences between Costa Ricans and Spanish-speaking US Latinos also were tested. The psychometric viability of a Spanish-language diabetes knowledge and client satisfaction measure with Costa Ricans was reviewed. METHODS The Diabetes Knowledge Questionnaire (DKQ) and the Client Satisfaction Questionnaire (CSQ) were administered to 162 Costa Rican adults with type 2 diabetes who were receiving services in the greater San Jose area. Sociodemographic, medical history, and anecdotal information also was collected. RESULTS More years of education, younger age, longer diabetes duration, and home glucose monitoring predicted diabetes knowledge. Home glucose monitoring and treatment with only oral hypoglycemics predicted significantly lower patient satisfaction. Costa Ricans exhibited greater diabetes knowledge than respondents in an earlier study with Spanish-speaking Latinos. CSQ psychometric limitations with Costa Ricans were identified. CONCLUSIONS The greater diabetes knowledge among Costa Ricans than US Latinos is likely due to more consistent, stable, and accessible care. Older, less educated, and newly diagnosed Costa Rican diabetes patients require more focused attention.

Abstract
OBJECTIVE Diabetes has held steady as the seventh leading cause of death in the U.S. since 2006. While aggregated data provide insights into how the country as a whole, or even as states, is faring with respect to diabetes mortality, disaggregation provides data that may facilitate targeted interventions and community engagement. RESEARCH DESIGN AND METHODS We analyzed deaths from diabetes for residents of Chicago to calculate age-adjusted diabetes mortality rates (AADMRs). We calculated AADMRs for Chicago by race/ethnicity and community area. We also examined the correlation between AADMR and 1) racial/ethnic composition of a community area and 2) median household income. RESULTS The AADMR for Chicago (27.5 per 100,000 population) was significantly higher than the national rate (22.5). Within both the U.S. and Chicago, the highest AADMRs were found among non-Hispanic blacks, followed by Hispanics, and then non-Hispanic whites. Within Chicago, Puerto Ricans displayed the highest AADMR at 45.7, compared with 35.0 at the national level. There was a strong positive correlation between the proportion of black residents in a community area and the AADMR (0.64). There was a strong negative relationship between household income and the AADMR for the entire city (-0.63) and for the predominantly black community areas (-0.52). CONCLUSIONS These data provide insight into where the worst diabetes mortality problems reside in Chicago. Our hope is that these data can be used to work toward the development of solutions to the very high diabetes mortality rates observed in several communities in Chicago and in similar communities throughout the U.S.

Abstract
BACKGROUND The prevalence of type 2 diabetes and diabetes-related morbidity and mortality is higher among low-income Hispanics when compared to that of Whites. However, little is known about how to effectively promote self-management in this population. PURPOSE The objectives were first to determine the feasibility of conducting a randomized clinical trial of an innovative self-management intervention to improve metabolic control in low-income Spanish-speaking individuals with type 2 diabetes and second to obtain preliminary data of possible intervention effects. METHODS Participants for this pilot study were recruited from a community health center, an elder program, and a community-wide database developed by the community health center, in collaboration with other agencies serving the community, by surveying households in the entire community. Participants were randomly assigned to an intervention (n = 15) or a control (n = 10) condition. Assessments were conducted at baseline and at 3 months and 6 months postrandomization. The intervention consisted of 10 group sessions that targeted diabetes knowledge, attitudes, and self-management skills through culturally specific and literacy-sensitive strategies. The intervention used a cognitive-behavioral theoretical framework. RESULTS Recruitment rates at the community health center, elder program, and community registry were 48%, 69%, and 8%, respectively. Completion rates for baseline, 3-month, and 6-month assessments were 100%, 92%, and 92%, respectively. Each intervention participant attended an average of 7.8 out of 10 sessions, and as a group the participants showed high adherence to intervention activities (93% turned in daily logs, and 80% self-monitored glucose levels at least daily). There was an overall Group x Time interaction (p = .02) indicating group differences in glycosylated hemoglobin over time. The estimated glycosylated hemoglobin decrease at 3 months for the intervention group was -0.8% (95% confidence intervals = -1.1%, -0.5%) compared with the change in the control group (p = .02). At 6 months, the decrease in the intervention group remained significant, -0.85% (95% confidence intervals = -1.2, -0.5), and the decrease was still significantly different from that of the controls (p = .005). There was a trend toward increased physical activity in the intervention group as compared to that of the control group (p = .11) and some evidence (nonsignificant) of an increase in blood glucose self-monitoring in the intervention participants but not the control participants. Adjusting for baseline depressive scores, we observed a significant difference in depressive symptoms between intervention participants and control participants at the 3-month assessment (p = .02). CONCLUSIONS Low-income Spanish-speaking Hispanics are receptive to participate in diabetes-related research. This study shows that the pilot-tested diabetes self-management program is promising and warrants the conduct of a randomized clinical trial.

Abstract
Hispanics are twice as likely as non-Hispanic Whites to have diabetes and are also at higher risk for diabetes-related complications and poorer outcomes. The prevalence of diabetes is inversely related to educational status. Low literacy is common, especially among older Hispanics. Little literature exists on formative research to create diabetes education materials for this audience. Two focus groups assessed views and preferences for diabetes education of low-literate, low-income, non-English-speaking urban Caribbean and Central American Hispanics with diabetes, as well as utility of materials developed specifically for this population, as part of the preliminary work for a pilot study of a diabetes intervention. Implications for practitioners and researchers are discussed.

Abstract
PURPOSE Cognitive interviewing techniques were used to adapt existing measures for use with a population of low-literate Spanish-speaking people with diabetes. METHODS Five individuals of Caribbean origin with diabetes participated in cognitive interviews for 4 instruments (measuring diabetes knowledge, quality of life, self-management, and depression) adapted for oral administration to low-literate individuals. Audiotaped interviews and handwritten notes were subjected to content analysis to identify problems across the 4 instruments as well as specific to a given instrument. RESULTS The following key problems were identified: general instructions were not helpful, items that were not specific enough generated a variety of interpretations, some wording was confusing, abstract concepts were difficult to understand, some terminology was unfamiliar, and interpretation of certain words was incorrect. CONCLUSIONS The data illustrate the usefulness of cognitive interviewing as a first step in the process of adapting measurement instruments.

Abstract
Fetal undernutrition has been hypothesized to program inappropriate metabolic responses to nutritional abundance in later life. Most studies have been conducted in industrialized countries. We studied the relationship between birth weight and risk factors for cardiovascular disease (CVD) among 187 men and 198 women age 20-29 y (mean age 24 y) who had participated in a longitudinal study conducted in Guatemala between 1969 and 1977. In women, birth weight was positively associated with adult body mass index (BMI; P < 0.01), systolic (P < 0.001) and diastolic blood pressure (P < 0.05), but not with glucose or any lipid measure. In men, birth weight was not associated with adult BMI, blood pressure or glucose, and was weakly and inversely related to total cholesterol and LDL cholesterol (test for trend: P = 0.06 and P = 0.09, respectively). Adult BMI was associated with increased prevalence of CVD risk factors in both men and women. Our data offer no support for the fetal programming of cardiovascular disease risk hypothesis in young adult women, and weak support in young adult men. Overweight in adults is a strong determinant of variance in CVD risk factor prevalence.

Abstract
OBJECTIVE To determine the effects of a culturally appropriate diabetes lifestyle intervention for Native Americans on risk factors for complications of diabetes. RESEARCH DESIGN AND METHODS A nonrandomized, community-based diabetes intervention trial was conducted in three Native American sites in New Mexico from 1993-1997. Participants were assigned to intervention or control based on community of residence. Intervention sessions were held approximately 6 weeks apart over approximately 10 months. The intervention was delivered in site A in family and friends (FF) groups (n = 32); site B received the same intervention in one-on-one (OO) appointments (n = 39); and site C received usual medical care (UC) (n = 33) (total participants, n = 104). Primary change in HbA(1c) level was assessed at 1 year. RESULTS Adjusted mean change in HbA(1c) value varied significantly across the three arms at 1 year (P = 0.05). The UC arm showed a statistically significant increase in adjusted mean HbA(1c) change (1.2%, P = 0.001), whereas both intervention arms showed a small nonsignificant (P > 0.05) increase in the adjusted mean change (0.5% and 0.2% for FF and OO arms, respectively). The increase was statistically significantly smaller in the combined intervention arms (0.4%) compared with the UC arm (1.2%, P = 0.02). CONCLUSIONS Lifestyle intervention has the potential to substantially reduce microvascular complications, mortality, and health care utilization and costs if the change is sustained over time.

Abstract
CONTEXT There are few studies of ethnic differences in cardiovascular disease (CVD) risk factors in older populations. OBJECTIVES To examine the association of ethnicity on CVD risk factors, after accounting for socioeconomic status (SES), and to examine health behaviors among those with CVD risk factors. DESIGN Third National Health and Nutrition Examination Survey, 1988-1994. SETTING Eighty-nine mobile examination centers. PARTICIPANTS 700 black, 628 Mexican-American, and 2192 white women and men age 65 to 84 years. MEASUREMENTS Ethnicity in relation to type II diabetes mellitus, physical inactivity, abdominal obesity, hypertension, cigarette smoking and non-high-density lipoprotein cholesterol (non-HDL-C). RESULTS After accounting for age and SES, both black and Mexican-American women had significantly higher prevalences of type II diabetes than white women. In addition, black women were significantly more likely to have abdominal obesity and hypertension and to be physically inactive than white women. Black men had significantly higher prevalences of hypertension and physical inactivity than white men. However, black men had lower prevalences of abdominal obesity than white men, and black women had lower prevalences of high non-HDL-C than white women. Among those with CVD risk factors, health behaviors were in need of improvement, especially among Mexican-American women whose primary language was Spanish. CONCLUSIONS In this national sample of older women and men, black and Mexican American women and black men were at the greatest risk for CVD. These findings parallel the heightened risk of CVD among younger ethnic minority populations and argue for appropriate primary and secondary prevention programs, modified for the language, cultural, and medical needs of older ethnic minorities.

Abstract
OBJECTIVE To examine whether there is a major gene effect on fasting insulin and pleiotropic loci for fasting insulin, total fat mass (FM), and abdominal visceral fat (AVF). RESEARCH METHODS AND PROCEDURES A major gene hypothesis for fasting plasma insulin levels was assessed using segregation analyses of data on 495 members in 98 normolipidemic sedentary families of white descent who participated in the HERITAGE Family Study. RESULTS Segregation analyses were performed on insulin adjusted for age, on insulin adjusted for age and FM, and on insulin adjusted for age and AVF. Before adjustment for AVF and FM, a major gene effect on fasting insulin levels was indicated. The putative locus accounted for 54% of the variance under a recessive inheritance pattern, affecting 11% of the sample (i.e., allele frequency = 0.33). However, after adjusting for the effects of AVF or FM, neither a major effect alone nor a multifactorial component alone could be rejected, and support for a major gene was equivocal, i.e., neither the hypothesis of Mendelian tau values or that of the equal tau(s) were rejected and the equal tau model fit the data better than the Mendelian tau model. This pattern (i.e., major gene evidence for insulin before but not after adjustment for AVF or FM) suggests that there is a putative locus with pleiotropic effects on both insulin and FM and another pleiotropic locus for both insulin and AVF. DISCUSSION Although these data do not directly support an additional major gene for insulin independent of AVF and FM, such support cannot be ruled out because there is still a significant major effect on FM- or AVF-adjusted insulin (albeit the Mendelian nature of this effect is ambiguous).

Abstract
OBJECTIVES To determine health-related quality of life for rural American Indians using an economical telephone surveillance system. DESIGN We interviewed 618 American Indians by telephone about health-related quality of life using an adaptation of the Behavioral Risk Factor Surveillance System questionnaire. RESULTS A smaller proportion of rural New Mexico American Indians (50.7%) reported their general health as 'excellent' or 'very good' compared to the overall New Mexico (58.2%) and US populations (57.9%). American Indians reported a mental health limitation more frequently than the New Mexico and the US populations. However, 13% fewer rural New Mexico American Indians reported a limitation in usual activities. Most limitations were due to musculoskeletal conditions or diabetes mellitus. Survey respondents were found to be representative of the rural American Indian population as reported by the 1990 US Census Bureau by tribal group affiliation and age, but were not representative by income, education, and gender. CONCLUSIONS Health-related quality of life for rural American Indians differs little from that of other New Mexicans and the general US population; however, when physical and mental health was rated as poor, fewer American Indians reported a limitation in usual activities. A telephone survey focusing on New Mexico American Indians is an efficient method by which to conduct surveillance of health-related quality of life.

Abstract
OBJECTIVE To adapt the Dartmouth COOP Charts for use among American Indians with diabetes and to evaluate the operating characteristics of the adapted charts because measures of health status have not been evaluated for use among American Indians with diabetes. RESEARCH DESIGN AND METHODS American Indian adults participated in focus group conferences to adapt and review the Dartmouth COOP Charts for use in American Indian communities. American Indian participants with diabetes were interviewed and administered the adapted charts. The operating characteristics of the charts were evaluated by measuring internal and external consistency, reliability, and acceptability. RESULTS Some of the wording and pictures were considered to be offensive and culturally inappropriate in American Indian communities. The adapted charts showed internal consistency in a comparison of interchart variables. CONCLUSIONS The adapted Dartmouth COOP Charts are more culturally acceptable than the original charts and appear to measure constructs adequately.

Abstract
OBJECTIVE As part of a study involving Japanese migrants, living in a developed city in the state of S. Paulo, Southeastern Brazil, a four-year experience of mortality among diabetic and non-diabetic subjects is described and their respective death rates are compared. In 1993, a cohort of 530 Japanese-Brazilians (236 issei or 1st generation and 294 nisei or 2nd generation) of both sexes, aged 40 from to 79 years old, were identified. RESEARCH DESIGN AND METHOD At that time, 91 (17%) were classified as non-insulin-dependent diabetic subjects (NIDDM), 90 (17%) with impaired glucose tolerance (IGT) and 349 (66%) as normal, according to WHO criteria. In 1996, families were questioned with a view detecting the deaths which had occurred among the subjects previously studied. This information, in addition to that from death certificates was used to record the date and the causes of death. Mortality rates for all causes and for specific causes (circulatory and renal diseases) were obtained for the three groups of subjects, by glucose tolerance status. Proportional hazard regression models were used to compare the mortality rates, adjusted for several covariables (gender, age, generation, hypertension, dyslipidemia, obesity and serum creatinine). RESULTS AND CONCLUSIONS Crude mortality rate ratios for all causes and specific causes, for NIDDM, and normal subjects were 2.95 (95% CI: 1.10-7.62) and 4.57 (95% CI: 1.31-16.48), respectively. No difference was observed between the crude mortality rate ratio for IGT and normal subjects. After simultaneous adjustments for the covariates, higher mortality rates for specific causes were observed among NIDDM than in the normal subjects (mortality rates ratio: 3.86; 95% CI: 1.11-13.38). These results in Japanese-Brazilians are consistent with previous reports of increased mortality in other diabetic subjects, thus confirming the adverse effect of this metabolic disturbance on mortality among diabetic subjects.
