  1. a Data were analyzed using multi-variable-adjusted logistic regression. Model 1: adjusted for age and education; Model 2: additionally adjusted for smoking, physical activity, urban or rural location, energy intake misreporting and information on whether a participant was on a diet and whether their dietary recall was typical of their habitual consumption; Model 3: additionally adjusted for body mass index
  2. b Analyses were based on n = 2324 due to exclusion of underweight men
  3. c Hypertension was defined as blood pressure ≥140/90 mmHg
