  1. Metabolic conditions: obesity, dyslipidaemia, and/or diabetes mellitus. Cardiovascular conditions: hypertension, myocardial infarction, angina, atrial fibrillation, heart failure, and/or stroke. Gastrointestinal conditions: irritable bowel syndrome, gastroesophageal reflux, coeliac disease, Crohn’s disease and/or ulcerative colitis. Musculoskeletal conditions: osteoarthritis, gout and/or osteoporosis
  2. R2 = Determination coefficient in %. Adjusted R2 for models including just sociodemographic, lifestyle, and mental health status variables were 27.2% for PCS and 23.4% for MCS
  3. Model 1: predicted means adjusted for sex, age, marital status, area of residence, educational level, working status, socioeconomic position (Socio-Economic Indexes for Areas Index of Relative Socio-economic Advantage and Disadvantaged), fruit/vegetable consumption, physical activity, smoking status, alcohol intake, and mental health status
  4. Model 2: predicted means adjusted for variables in model 1 + mutual adjustment between the cluster intragroup of chronic conditions
