Results are from regression models for each of SBP, DBP, HOMA-IR, logarithm of fasting plasma glucose, total cholesterol and logarithm fasting triglycerides with waist circumference.

For the significance of each slope compared to zero slope in each model,

^*p<0.05;

^**p<0.01;

^***p < 0.001.

For the comparison of slopes between urban and rural Cameroon,

A = p<0.05

B = p<0.01

C = p < 0.001.

For the comparison of slopes between urban Cameroon and France,

X = p<0.05

Y = p<0.01;

Z = p < 0.001.
