Abstract
Aims: To compare body mass index (BMI), waist circumference (WC) and waist-to-hip ratio
(WHR) as determinants of type 2 diabetes (T2DM) and determine optimal cut-offs in a
sub Saharan African population.
Methods: Data from the RODAM study including Ghanaians aged 25–70 living in rural
Ghana, urban Ghana and Europe were used. Logistic regression was used to assess
associ ations between BMI, WC, WHR and T2DM status, by sex and site. Area under the curve
(AUC) were constructed to discriminate between indices and establish performance and
cut-off values.
Results: WHR had the strongest association with T2DM in men and women across sites,
except for rural men. The highest adjusted odds ratio (aOR) and AUC were in rural women
for WHR (aOR = 2.09, 95%CI = 1.47–2.99; AUC = 0.71). Among migrants, WHR had higher
