Plot of odds ratio (OR) of hypertension by tertile of Dietary Guideline Index (DGI) in men included in the Australian Health Survey stratified by a BMI status and b central adiposity, determined by multivariable logistic regression, with 95 % confidence intervals. Analyses were adjusted for age, education level, smoking, physical activity, urban or rural location, energy intake misreporting, information on whether a participant was on a diet and whether their dietary recall was typical of their habitual consumption. Tertile 1 of the DGI represented the lowest (unhealthiest) score and was used as the reference (OR = 1). Underweight men (n = 22) were excluding from the BMI stratification analysis. Normal weight (n = 630) was defined as BMI ≥ 18.5 and <25 kg/m2; Overweight or obese (n = 1694) was defined as BMI ≥ 25 kg/m2. Central adiposity (n = 1480) was defined as waist circumference >102 cm and no central adiposity (n = 866) as waist circumference ≤102 cm
