  • Age is given as the mean plus SE. Other values are given as the age-adjusted mean (if appropriate) with SEs in brackets for continuous variables and as age-adjusted percentages for dichotomised or categorical variables. P values denote the statistical significance of the difference in each variable between 1967 and 2012. Overweight was defined as a BMI ≥25.0 kg/m2. Underweight was defined as a BMI <18.5 kg/m2. Smoking habits were categorised as never smokers or current/former smokers. Alcohol intake was defined as current or not. Hypertension was defined as blood pressure ≥140/90 mm Hg and/or current use of antihypertensive agents. Numbers of subjects with missing data were as follows: alcohol intake: 20, hypertension: 4, antihypertensive medication: 10 and living alone: 9 in men in 1967; living alone: 1 in men in 2012; smoking habit: 2, alcohol intake: 42, hypertension: 3, antihypertensive medication: 5 and living alone: 25 in women in 1967; no missing data in women in 2012.
