Serum lipoprotein (a) (Lp (a)) and its correlates were studied in African Aboriginal Pygmies (n=146) and Bantus (n=208) from Cameroon.
Geometric mean Lp (a) levels were 274 and 289 mg/l in Bantu males and females, respectively, and 220 and 299 mg/l in Pygmy males and females, the gender difference being significant in Pygmies (p=0.024).
In Pygmies 41% and 52% of the males and females, respectively, had Lp (a) levels above 300 mg/l, compared with 47% and 55% in Bantus.
Overall, Lp (a) levels did not significantly differ between Pygmies and Bantus, and did not correlate with age, body mass index (BMI), systolic and diastolic blood pressure.
Compared with healthy Asian and Caucasian population samples, age-and BMI-adjusted geometric Lp (a) means were 2.3 to 5.0-fold higher in Pygmy and Bantu males, and 2.9-to 3.6-fold higher in Pygmy and Bantu females (p ¾ 0.05).
Across the population samples studied ethnicity predicted 12% and 17% of serum Lp (a) variance in males and females, respectively.
