  1. Normal lipid profile values were those < 75th percentile for age and sex, moderate risk > 75th percentile and < 90th percentile, and high risk ≥ 90th percentile. For comparison between adolescent and adults percentiles were used. ILP was determined as being ≥ 85th percentile adjusted for age and sex. Normal blood cholesterol level in adults = TC < 200 mg/dl (5.2 mmol/L), moderate risk as 5.2 to 6.2 mmol/L and high risk if > 6.2 mmol/l (240 mg/dl). For LDL cholesterol; normal if < 3.4 mmol/L (130 mg/dl), moderate risk as 3.4 to 4.1 mmol/L and high risk if > 4.1 mmol/L (159 mg/dl). HDL cholesterol was defined at high risk if < 0.9 mmol/L (35 mg/dl). TRG levels was normal if < 2.8 mmol/l (250 mg/dl), moderate risk as 250–500 mg/dl and high risk if > 5.6 mmol/L (500 mg/dl). [38]
