Abstract
A community-based program to reduce salt consumption in order to lower general blood pressure levels was started in North Karelia, a county in eastern Finland with high hypertension and CVD [cardiovascular disease] rates. The feasibility and effects of this new community program to reduce salt intake are evaluated. The study period is from spring 1979 to spring 1982. At the outset and at the end, cross-sectional random population samples, ages 14-65, are examined both in North Karelia and a matched reference community. The surveys include, among other measurements, 24-h urine collection (for Na, K and creatinine excretion) and blood pressure. Principles and methods of intervention are presented. Preliminary results from the baseline survey confirmed the high salt intake of the population. The mean 24-h urinary Na excretion was 215-218 and 171-173 mmol, K excretion values were 89-91 and 72-73 mmol and Na/K ratios were 2.5-2.6 and 2.4-2.5, respectively, for men and women.
