This paper identifies naturally occurring lifestyle and self-care practices in managing type 2 diabetes mellitus that are associated with good glycemic control. In-depth, qualitative interviews were conducted in Guadalajara, Mexico, with 31 matched pairs of good and poor control diabetic patients (n=62), who were matched on their duration of disease and use of medications. While many themes were listed by both groups, a comparison of the responses indicated that themes of daily exercise with a preference for walking, eating beef and milk rather than chicken and fish, economic issues, and emotional issues distinguished poor-control patients. Good-control patients were more likely to have a negative reaction to their initial diagnosis, take a more comprehensive approach to control, eat only two meals a day (plus snacks), use noncaloric beverages to satisfy desires for more food, and know what their blood sugar levels should be.
