OBJECTIVE -We examined if active family nutritional support is associated with improved metabolic outcomes for Diné (Navajo) individuals living with type 2 diabetes.RESEARCH DESIGN AND METHODS -The presence of family support, using variables identified in earlier ethnographic research, was assessed via surveys in a convenience sample of 163 diabetic individuals. Diabetes outcome measures (HbA 1c , serum glucose, triglycerides, total cholesterol, creatinine, and systolic and diastolic blood pressure measures) were extracted from participants' medical records. Bivariate analyses and multiple logistic regressions were conducted.RESULTS -All measures of family support showed a relation with one or more indicators of metabolic control in bivariate analyses. In multivariate analyses, respondents were more likely to be in the best tertile for triglyceride (P Ͻ 0.05), cholesterol (P Ͻ 0.05), and HbA 1c (P Ͻ 0.05) if another person cooked most of the meals. Respondents in families who bought/cooked "light" foods were more likely to be in the best tertile for triglyceride (P Ͻ 0.005) and cholesterol levels (P Ͻ 0.005), and those in families whose members ate "light" foods with them were more likely to be in the best tertile for triglycerides (P Ͻ 0.005). When all three support variables were entered into a multivariate model, only the variable "other family members cook the majority of the meals" was significantly associated with being in the lowest triglyceride (P ϭ 0.05), HbA 1c (P Ͻ 0.05), or cholesterol tertiles (P Ͻ 0.05). These relationships were most evident for women with diabetes.CONCLUSIONS -Active family nutritional support, as measured by culturally relevant categories, is significantly associated with control of triglyceride, cholesterol, and HbA 1c levels. The findings suggest that the family is a more useful unit of intervention for Diné individuals than for the individual alone when designing diabetes care strategies.
Diabetes Care 26:2829 -2834, 2003D iabetes has reached epidemic proportions among the Diné (Navajo): over one in five adults aged Ն20 years (22.9%) have diabetes, which is a prevalence rate five times higher than the age-standardized rate for the U.S. population as a whole (1). Among Diné individuals aged 45-64 years and Ն65 years, diabetes prevalence rates increase to 40.1 and 41.3%, respectively (1). Complications from the disease can also be devastating. Nearly one-third (30.9%) of those with the disease had cardiovascular disease, which is a rate 5.2 times greater than age-and sex-matched Diné without diabetes (2). Cerebrovascular disease, peripheral vascular disease, microalbuminuria, and hospital admissions occurred at rates 10.2, 6.8, 4, and 2 times greater, respectively, for Diné with diabetes than for those without the disease (2-4). Among Diné with diabetes, 30% reported problems with vision, 20% with feet, and 17% with kidneys (1). Thus, identification of factors that improve metabolic control in the disease is of paramount importance to the Diné.Fisher et al. (5) have identified f...
