“…17 One of the reasons for high blood pressure in rural Japan was due to a high salt intake in rural areas. 26 There was a remarkable difference in the level of blood pressure and the prevalence of hypertension among geographic regions in China. Generally speaking, the prevalence of hypertension was higher in the north than in the south, particularly in the Qingzang plateau region around the Tibetan and northeast areas.…”

Hypertension is a major risk factor for cardiovascular disease in Chinese and Japanese with a low to moderate serum cholesterol level. The prevalence of hypertension is diverse in Chinese populations with different geographic region, lifestyles and cultures. The same diversity was observed in Japan in the past, but recently the regional difference has become smaller. The large decline in stroke mortality in Japan was followed by a reduction in the prevalence of hypertension and the lowering level of blood pressure. This is partly explained by various community-based hypertension control programmes. Chinese populations are now showing similar patterns as those observed in Japan. These populations

“…13,14 According to the National Nutrition Survey 15 average salt consumption in Japan had decreased yearly, from 13.5 g in 1975 to 11.7 g in 1987. However, the three study centres examined in the Intersalt Study (Osaka, Tochigi and Toyama) showed relatively high sodium excretion compared to other countries.…”

Using the identical protocol of an Intersalt Study previously conducted, we undertook a new study (Intersalt-2) 8 years later. We measured changes in various factors affecting blood pressure (BP) including urinary sodium and potassium excretion in three districts of Japan: Osaka, Tochigi, and Toyama. Also we evaluated the trends in the relationships of those factors to BP.The Intersalt Study revealed that the average sodium excretion of all three study centres was high (particularly in Toyama) while potassium excretion was relatively low. The sodium/potassium ratio was therefore relatively high. The body mass index (BMI) was favourable, but the prevalence of heavy alcohol drinkers was high.Comparing the first to the second study reveals a decrease in sodium excretion in Toyama, although that

“…In Japan, salt intake of more than 20 g/day (340 mmole/day) has been reported (Sasaki 1962). Recent data indicate a range from 10.8 g (185 mmole) to 14.0 g (239 mmole) by the National Nutrition Survey of Japan in 1986 (Ministry of Health and Welfare 1988).…”

“…In some areas of northern Japan, the average salt intake was reported to be over 25 g daily (Sasaki 1962). There still remains regional variation of salt intake, though recently the level of intake has diminished (Ministry of Health and Welfare 1988).…”

The cross-sectional association of blood pressure with urinary sodium and potassium excretion was investigated with a stepwise regression analysis. Spot urine of 7441 females between 40 and 69 years was collected from 169 municipalities (88 urban and 81 rural) covering all prefectures in Japan. The filter paper sampling technique for urine was used to collect samples of subjects from March to December in 1985. Spot urine samples were analyzed for sodium, potassium and creatinine. In addition, 24-hr sodium and potassium excretions were estimated by predictive equations. Blood pressure, sodium excretion and sodium/potassium ratios were higher in rural areas than in urban areas. Consistent positive correlations between urinary sodium and blood pressure, and negative correlations between urinary potassium and blood pressure were observed in the whole country of Japan, in both urban and rural areas, and also in separate observations of twelve regions in Japan with some exceptions. When compared in standardized partial regression coefficients, relative effects of potassium on systolic blood pressure were higher than those of sodium in the whole of Japan, in urban and rural areas, and in five among the twelve regions. The present Japanese study confirmed a positive within-population relationship between sodium excretion and blood pressure and a negative relationship between potassium excretion and blood pressure.
