Robust evidence of the association of insulin resistance and metabolic syndrome with acne in male patients is lacking.
To assess the prevalence of metabolic syndrome and insulin resistance in male patients 20 years or older with acne.
Design, Setting, and Participants
We performed a cross-sectional study in 100 male patients with acne and 100 age-matched male controls without acne from a dermatology outpatient department of a tertiary care institute. Postadolescent patients were recruited only to negate the effects of physiologic insulin resistance that are seen at the time of puberty and adolescence. Twenty-five patients were included in each of the 4 individual severity groups according to the Global Acne Grading System and were age matched to 100 male controls without acne.
Clinical examination, Global Acne Rating System, National Cholesterol Education Programme Adult Treatment Panel III (NCEP-ATP III), and Homeostasis Model Assessment–Insulin Resistance (HOMA-IR).
Main Outcomes and Measures
Metabolic syndrome was diagnosed as per the criteria of the modified NCEP-ATP III. Insulin resistance was assessed by the HOMA-IR. A HOMA-IR value greater than 2.5 was arbitrarily considered as insulin resistance.
Prevalence of insulin resistance was significantly higher in cases (22%) compared with controls (11%) (P = .03). The prevalence of metabolic syndrome was comparable between cases (17%) and controls (9%) (P = .09). Prevalence of insulin resistance and metabolic syndrome did not differ significantly among the acne severity groups.
Conclusions and Relevance
Postadolescent male patients with acne more commonly have insulin resistance. This resistance may be a stage of prediabetes, and the patients may develop hyperinsulinemia or type 2 diabetes in the future. These patients should be followed up for a prolonged time to determine whether they develop conditions associated with insulin resistance.
