Age and Glycemic Control Among Low-Income Latinos

Abstract  

Younger adult patients with diabetes often have poorer glycemic control (HbA1c) than older patients. It is not known if this
relationship holds true in the Latino population. Objective was to explore the relationship between age and HbA1c in a Mexican
American population and what plausible factors might mediate this relationship. We analyzed data from 387 patients with diabetes
self-identified as Mexican American recruited as a part of a cross-sectional study of safety net patients in two cities. Patients
completed questionnaires and their last HbA1c was extracted from the medical record. We conducted multivariate regression
analyses and Baron and Kenny tests of mediation. Participants were young with mean age of 53 ± 12 years. Younger age was associated
with a higher HbA1c and having a higher fat diet. High fat diet partially mediated the relationship between age and HbA1c
(p < 0.001 to p < 0.01). Age’s indirect effect on HbA1c through diet was significant (Sobel = −2.44, p = 0.01). Younger Mexican American patients had higher HbA1c compared to older patients. Having a diet high in fat partially
explained this relationship. Future epidemiological studies are needed to understand the multifaceted relationship between
age and glycemic control.
