Salt intake has been reported to be high in Japanese population. The aim of this study is to investigate the long-term compliance of salt restriction in Japanese hypertensive outpatients. Participants were recruited from hypertensive outpatients who visited at the National Kyushu Medical Center. Patients with secondary hypertension or diabetic nephropathy were excluded. Subjects included 389 patients, 230 women and 159 men, mean age 58±11 years, who underwent successful 24-h home urine collection more than three times over an interval of a year. Urinary salt, potassium, protein, uric acid, and urea nitrogen were measured. Additionally, alcohol consumption, smoking habit, physical activities, quality of life scores, and job status were assessed by use of the questionnaire. During the follow up period (average 3.5 years), participants underwent urine collection 4.6 times in average. Urinary salt excretion at the last visit was significantly lower than that of the first visit (8.7±3.4 vs. 9.6±4.1 g/day, p
