Abbreviations: BMI, body mass index; BP, blood pressure; LDL, low-density lipoprotein; HDL, high-density lipoprotein; MetS, metabolic syndrome; NS, not significant.
Data are means ± standard deviation (SD). P-values are adjusted for age; P-values for blood pressure, cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, and glucose are also adjusted for BMI.
