Objective

Latino adults are 66% more likely to have diabetes relative to non-Latino white adults. Prior research identifies depression as a significant risk factor for metabolic syndrome (MetS), but research examining this among Latinos is lacking. This study sought to examine the links between depression and MetS and clinically significant elevations in cardiovascular disease risk markers of MetS in a sample of community-dwelling older Latinos with type 2 diabetes.

Methods

Participants were 332 community-dwelling older (≥60 years) Latinos with type 2 diabetes who completed the nine-item Patient Health Questionnaire and received a health checkup assessing body mass index (BMI), triglyceride and high-density lipoprotein (HDL) cholesterol levels, and blood pressure. Logistic regression analysis compared MetS rates of those meeting criteria for depression with those who did not. Secondary analyses examined the associations between depression and individual MetS components. All analyses controlled for demographic (e.g., income, age) and other potential MetS risk factors (e.g., smoking status, physical activity, alcohol level consumption).

Results

Depression was significantly associated with an increased risk of MetS (OR: 5.79; 95% CI: 1.32–25.42) and clinically significant elevations in triglycerides (OR: 2.71; 95% CI: 1.15–6.42) and reduced (HDL) cholesterol (OR: 2.46; 95% CI: 1.11–5.45). A significant association was not observed between depression and either BMI or hypertension.

Conclusion

Depression is significantly linked to MetS, and most notably dyslipidemia, in older Latinos with diabetes. Causation, however, cannot be inferred from these analyses given the cross-sectional nature of the study. Future research should prospectively examine the directionality of this effect.

Participants

Participants were 332 Latino, community-dwelling older adults recruited from two primary care facilities in San Diego County, California. All 332 participants were enrolled in the Salud Program, an evaluation study examining the implementation of two evidenced-based psychosocial interventions in patients with diabetes and concurrent depression/high risk of depression. Assessments for both clinics were administered approximately 2 weeks before initiating the respective interventions. Potential

Sample Characteristics

Characteristics of the sample can be found in Table 1. Of the 332 participants, 256 (77.1%) met criteria for MetS, which is similar to other studies reporting the prevalence of MetS in individuals with diabetes.6, 7 For each of the specific MetS criteria, 288 participants (86.7%) met criteria for hypertension, 168 (50.6%) met criteria for obesity, 199 (59.9%) met criteria for elevated triglycerides, and 90 (27.1%) for low HDL-C.

Discussion

MetS is a known risk factor for developing CVD,7 particularly among Latinos.4 The current study sought to understand the relationship between depression and MetS in older Latinos with diabetes. We found that compared with nondepressed diabetics, the presence of major depression was related to significantly higher risk for MetS (odds ratio: 5.79; 95% confidence interval: 1.32–25.42) in an older Latino sample. These effects remained significant after controlling for age, sex, years residing in

      To our knowledge, the association between depression and metabolic syndrome has not been investigated in other populations of type 1 diabetes. In a group of elderly participants with type 2 diabetes, however, depression was significantly associated with an increased risk of metabolic syndrome and, comparable to the current observations, dyslipidaemia in particular [29]. Moreover, as seen in the current study, depression was not associated with either BMI or hypertension.
