BMI is body mass index in units of kilograms divided by meters squared (kg/m²). BP is blood pressure in units of millimeters of mercury (mmHg). HR is heart rate in units of beats per minute (bpm). AUDIT is the Alcohol Use Disorders Identification Test [37]. Exercise variables are from the Short Form of the International Physical Activity Questionnaire (IPAQ-SF) [38] in units of metabolic equivalent of task minutes per week (METmpw). Two MANOVA models were performed: one with health indicators and one with health behaviors. Italics highlight values reaching statistical significance (α = 0.05).
