Acculturation, Dietary Behaviors, and Macronutrient Intake Among Mexican Americans With Prediabetes: The Starr County Diabetes Prevention Initiative

PURPOSE

The purpose of the study was to examine the influences of sex and acculturation on dietary behaviors, macronutrient intake, and dietary quality in participants enrolled in a diabetes prevention initiative in Starr County, Texas.

METHODS

Baseline data from the Starr County diabetes prevention study (N = 300) were analyzed-acculturation (country of origin, years in Starr County, language and food preferences), depressive symptoms (Patient Health Questionnaire-9), healthy eating self-efficacy (Weight Efficacy Lifestyle Questionnaire-Short Form), diet quality (USDA Healthy Eating Index), fat avoidance (Fat Avoidance Scale, Spanish version), and macronutrients. Descriptive statistics and univariate analysis of covariance were used to examine differences based on acculturation, controlling for sex.

RESULTS

Participants were predominantly female (73%) and, on average, 51 years of age. Language and food preferences favored Spanish language and Hispanic foods, respectively. The majority (71%) was born in Mexico but had resided in Starr County for 33 years, on average. Depressive symptoms were moderate, and eating self-efficacy scores suggested low confidence in making healthy food choices, particularly for saturated fats. Spanish language preference was associated with worse dietary habits. The mean dietary quality score was lower than the national average (54 vs 59 nationally); females had slightly higher dietary quality than males and a higher mean fat avoidance score, although differences were not clinically significant. Intakes of carbohydrate, saturated fats, and cholesterol were higher than recommended daily allowances.

CONCLUSIONS

The overall preference for speaking Spanish and the influence of language on dietary intake should inform future dietary interventions. Accommodating cultural norms and food preferences remain major challenges to improving dietary quality among the diverse Hispanic ethnic groups.

Effectiveness of workplace diabetes prevention programs: A systematic review of the evidence

PURPOSE

The primary purpose is to review diabetes workplace interventions and the degree to which they improve diabetes-related outcomes in employees diagnosed with or at risk for T2DM.

METHODS

Three electronic databases and ancestry searches were used to identify peer reviewed articles published in English from 2000 to June 2017.

RESULTS

The number of participants represented by the 22 selected studies, excluding one large outlier, was 4243. On average, the samples were 57% female and ethnically diverse. Interventions-healthy eating behaviors, physical activity, and/or monitoring and self-managing diabetes and cardiovascular risk factors-were delivered in group sessions of fewer than 20 employees. Programs involved 1-h weekly sessions held during lunch hour or at other times during the workday for 12 to 24 weeks. Study outcomes, commonly measured at 6 and/or 12 months, were consistently positive.

CONCLUSION

The literature search uncovered beginning evidence that workplace interventions hold promise for preventing diabetes and/or its complications. More rigorous, creatively designed, workplace studies, are needed for employees at high-risk for developing diabetes.

PRACTICE IMPLICATIONS

Implications include the need for employer education about the benefits of employer support for such programs and attention to motivational strategies so employees will take full advantage of programs that are offered.

A randomized clinical trial of diabetes self-management for Mexican Americans: Are there serendipitous health benefits for supporters of study participants?

Objectives:

Studies of social support in diabetes have focused on the effects of support on the person with type 2 diabetes. We explored diabetes prevention effects of a culturally tailored diabetes self-management intervention in individuals without diabetes who were supporters of intervention participants.

Methods:

This is a secondary analysis of data from a randomized clinical trial that involved 256 Mexican Americans with diabetes. Each study participant designated a supporter—spouse, relative, friend—who attended intervention sessions and assisted participants in attaining effective diabetes self-management. Supporter’s glycosylated hemoglobin (A1C) data were tracked for 1 year to determine diabetes conversion rates in supporters without diabetes at baseline.

Results:

Fewer individuals in the intervention group (n = 9) converted to an A1C above the 7% threshold, compared to the 1-year wait-listed control group (n = 16). We found a statistically significant difference (p = .021) at 12 months in the number of individuals whose A1C was ⩽8%, with fewer supporters above threshold in the intervention group (reduction of 48%). Supporters in the intervention group with prediabetes, based on baseline A1C, experienced a slight reduction in A1C, while control group supporters with prediabetes experienced an increase.

Discussion:

The results suggest that there are potential benefits for family members and other supporters of persons with diabetes who participated in diabetes self-management programs.

Insulin therapy and type 2 diabetes: management of weight gain

The potential for insulin-related weight gain in patients with type 2 diabetes presents a therapeutic dilemma and frequently leads to delays in the initiation of insulin therapy. It also poses considerable challenges when treatment is intensified. Addressing insulin-related weight gain is highly relevant to the prevention of metabolic and cardiovascular consequences in this high-risk population with type 2 diabetes. In addition to lifestyle changes (eg, diet and exercise) and available medical interventions to minimize the risk of weight gain with insulin treatment, familiarity with the weight gain patterns of different insulins may help deal with this problem. The use of basal insulin analogs may offer advantages over conventional human insulin preparations in terms of more physiologic time-action profiles, reduced risk of hypoglycemia, and reduced weight gain.
