In 1972 a cardiovascular disease prevention programme was started in North Karelia in Eastern Finland. At the outset of the programme a random sample comprising 10 940 persons aged 25 to 59 years was studied. Those subjects whose systolic blood pressure was ≥175 and/or diastolic ≥100 mmHg or who were undergoing antihypertensive treatment, were re-examined in 1977. Their body weight was measured both in 1972 and 1977. The changes in their physical activity, smoking and eating habits were also interviewed. The men aged 25 to 49 years had increased their body mass index by 0.4 kg/m 2 and the men aged 50 to 59 years by 0.2 kg/m 2 , on average. In women (aged 25 to 49 years) body mass index had increased by 0.5 kg/m 2 but decreased in the age group 50 to 59 years by 0.2 kg/m 2 , on average. In men the change in body weight exerted the strongest partial regression on the change in smoking, age and physical activity (both in leisure time and at work). In women aged 25 to 49 years the reasons for increased body weight were the same as in men. In older women, aged 50 to 59 years the decrease in body weight was associated with age, change in amount of smoking and initiation of antihypertensive drug therapy.
