waist–hip circumference ratio (W/H ratio):
healthy range <0.9—a better predictor of
________ than BMI
cardiovascular risk
4 skinfold thickness______,_______, ______ and ______—for
calculation of percentage body fat
(sum of suprailiac,
subscapular, triceps and biceps skinfolds)
________ which is defined as a
W/H ratio of >0.85 in women and >0.95 in men,

diabetes
