Table 4 Prevalence of MES (with relative risk) and indicators of cardiovascular risk (split according to gender)

From: The prevalence of metabolic syndrome amongst patients with severe mental illness in the community in Hong Kong – a cross sectional study

  Male n = 62, (%) Female n = 77, (%) Total n, (%) χ 2, P-value*
Metabolic Syndrome present 19 (31) 30 (39) 49 (35) NS
Relative Risk of Metabolic Syndrome (95% CI, P value)** 1.737 (1.18-2.54, p < 0.01) 2.230 (1.67-2.97, p < 0.01) 2.008 (1.59-2.53, p < 0.01)
BMI overweight- Hong Kong criterion (≥23) 48 (77) 63 (82) 111 (80) NS
BMI overweight- International criterion (≥25) 34 (55) 45 (58) 79 (57) NS
Waist Circumference (males ≥90 cm, females ≥ 80 cm) 20 (32) 47 (61) 67 (48) χ 2 = 11.40, p < 0.01
Hypertension – Blood pressure ≥ 140/90 12 (19) 21 (27) 33 (24) NS
Hypercholesterolemia – Total Cholesterol ≥6.2 mmol/L 15 (24) 16 (21) 31 (22) NS
Raised LDL cholesterol – LDL ≥ 4.1 mmol/L 11 (18) 12 (16) 23 (16) NS
Reduced HDL cholesterol – HDL <1.00 mmol/L (males), <1.30 mmol/L (females) 13 (21) 19 (25) 32 (23) NS
Raised fasting plasma glucose - ≥ 7.00 mmol/L 8 (13) 9 (12) 17 (12) NS
Raised triglycerides - ≥2.2 mmol/L 17 (27) 17 (22) 34 (25) NS
  1. *P for significant differences in cardiovascular risk according to gender, tested by χ 2 test.
  2. NS = not statistically significant.
  3. ** Data reported by Ko and Tang [6] for the prevalence of MES in the general Hong Kong population was used to calculate the relative risk in this sample.
