Prevalence of metabolic syndrome among adults treated at a district hospital outpatient department

Abstract

Background: Metabolic syndrome (MetS) is a collection of risk factors, including hypertension, high fasting blood glucose, high fasting triglyceride and low high-density lipoprotein (HDL) cholesterol levels that may increase the risk for cardiovascular disease and type 2 diabetes. The study aimed to determine the prevalence of MetS among adults attending a Free State district hospital’s outpatient department.

Methods: A cross-sectional study included a consecutive sample of consenting patients 18 years and older from 18 October 2021 to 19 November 2021. Patients’ waist circumference was measured, and data were extracted from patients’ files.

Results: The 409 participants were predominantly females (64.2%). The median age was 60 years. Triglyceride and HDL cholesterol levels were available for 27.4% and 26.9% of patients, respectively. Of the 278 (68.0%) patients with sufficient information to determine their MetS status, 187 (67.3%) had MetS. Of the males with sufficient information, 49.1% (n = 56/114) had MetS compared to 79.9% (n = 131/164) of the females with sufficient information (p < 0.001). The age group 60–79 years had the highest prevalence (76.7%, p < 0.001). In all race groups, at least two-thirds of patients had MetS (p = 0.831).

Conclusion: Incomplete patient notes and failure to do investigations led to a third of patients not having sufficient information to determine their MetS status. In patients with sufficient information, a high prevalence of MetS was found.

Contribution: This study highlights the challenges of determining MetS retrospectively in an outpatient population and the need for completeness of medical note keeping and routine investigations in high-risk patients. It also notes the high prevalence of MetS.
