text: Yo, check it out, we got a study in the house,
  Tryna set some cut-off points, let me break it down.
  We talkin' waist:hips girth ratio, that's the game,
  Lookin' at hypertension, that's the aim, uh huh.
  
  Back in '95-'96, in Rio de Janeiro town,
  They surveyed 3,282 peeps, holdin' it down.
  Two-stage sample, let me give you the scoop,
  Sixty census tracts first, then households in the loop.
  
  They measured weight, stature, waist, and hips,
  Blood pressure too, no time for any skips.
  Hypertension defined by systolic over 140,
  Or diastolic over 90, medication plenty.
  
  Now let's talk sensitivity and specificity,
  Calculatin' cut-off points, we're gettin' busy.
  Predictin' hypertension, depending on factors,
  Sex, age, overweight, we're breakin' it down backwards.
  
  The World Health Organization, they got guidelines,
  Classifyin' overweight, keepin' it real fine.
  For the best cut-off points, listen up, don't miss,
  Men need 0.95, while women go for 0.80, this is it.
  
  When it comes to predictin' hypertension, no doubt,
  WHR's the champ, it's what we found out.
  Less correlated with body mass index, you see,
  Outperformin' waist:stature and waist circumference, no plea.
  
  So there you have it, the facts are laid,
  In the language of rap, this study was made.
  Cut-off points for WHR, hypertension's foe,
  Now you know the deal, and that's how we flow.
