Menstrual irregularity (84.7% vs. 70.9%; RR 1.19), hirsutism (65.9% vs. 58.8%; RR 1.10), acne (44.9% vs. 36.8%; RR 1.25), acanthosis nigricans (52.7% vs. 22.6%; RR 1.94), and biochemical hyperandrogenism (45.6% vs. 31.8%; RR 1.49) were more prevalent in obese than in lean PCOS. Obese PCOS was associated with a less favourable cardiometabolic profile, with higher HOMA\u2010IR (MD 2.03), fasting (MD 5.12\u2009mg\/dL), and 2\u2010h (MD 9.91\u2009mg\/dL) plasma glucose, and greater risks of prediabetes (25.3% vs. 12.1%; RR 1.84), diabetes (8.6% vs. 2.7%; RR 2.58), and metabolic syndrome (51.2% vs. 11.9%; RR 3.59). Mean lipid levels were worse in obese PCOS, with higher total cholesterol, triglycerides, and LDL cholesterol, and lower HDL cholesterol. Nonetheless, lean PCOS exhibited substantial burdens of menstrual dysfunction, hyperandrogenism, insulin resistance, dysglycemia, and dyslipidemia.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Obesity in PCOS is associated with more severe reproductive, metabolic, and hormonal abnormalities, but lean PCOS still carries substantial reproductive and metabolic burdens.
