“…Four articles examined the association between salt intake and risk of CVD mortality [ 41 , 72 , 73 , 74 ] ( Table S3 ) using the results of two cohort studies (NIPPON DATA80 and JACC). Two reports on NIPPON DATA80 [ 41 , 74 ] and the other two reports on JACC [ 72 , 73 ] differed in quantiles, unit of salt consumption, and period of follow-up. The pooled RR for CVD mortality compared with the highest to lowest consumption of salt was 1.18 (95% CI: 1.03–1.34, p = 0.013, I 2 = 63%, Egger’s test: p = 0.243), indicating significant risk increment in the group with higher salt intake ( Table 2 , Figure 7 A).…”

This systematic review and meta-analysis elucidate the effects of the Japanese-style diet and characteristic Japanese foods on the mortality risk of cardiovascular disease (CVD), cerebrovascular disease (stroke), and heart disease (HD). This review article followed the PRISMA guidelines. A systematic search in PubMed, The Cochrane Library, JDreamIII, and ICHUSHI Web identified prospective cohort studies on Japanese people published till July 2020. The meta-analysis used a random-effects model, and heterogeneity and publication bias were evaluated with I2 statistic and Egger’s test, respectively. Based on inclusion criteria, we extracted 58 articles, including 9 on the Japanese-style diet (n = 469,190) and 49 (n = 2,668,238) on characteristic Japanese foods. With higher adherence to the Japanese-style diet, the pooled risk ratios (RRs) for CVD, stroke, heart disease/ischemic heart disease combined (HD/IHD) mortality were 0.83 (95% CI, 0.77–0.89, I2 = 58%, Egger’s test: p = 0.625, n = 9 studies), 0.80 (95% CI, 0.69–0.93, I2 = 66%, Egger’s test: p = 0.602, n = 6 studies), and 0.81 (95% CI, 0.75–0.88, I2 = 0%, Egger’s test: p = 0.544, n = 6 studies), respectively. Increased consumption of vegetables, fruits, fish, green tea, and milk and dairy products decreased the RR for CVD, stroke, or HD mortality. Increased salt consumption elevated the RR for CVD and stroke mortality. Increased consumption of dietary fiber and plant-derived protein decreased the RR for CVD, stroke, and HD/IHD mortality. The Japanese-style diet and characteristic Japanese foods may reduce CVD mortality. Most studies conducted diet surveys between 1980 and the 1990s. This meta-analysis used articles that evaluated the same cohort study by a different method. A new large-scale cohort study matching the current Japanese dietary habits is needed to confirm these findings.

Asia is a large continent and there is significant diversity between countries and regions. Over the last 30 years, absolute blood pressure (BP) levels in Asia have increased to a greater extent than those in other regions. In diverse Asia-Pacific populations, for choosing an Asia-specific approach to hypertension management is important to prevent target organ damage and cardiovascular diseases. In this consensus document of HOPE Asia Network, we introduce seven action approaches for management of hypertension in Asia.

“… 79) Another study using the same data (n=8,702) showed that an increment of 2 g/1,000 kcal in household salt intake was associated with the increased risk of total CVD, coronary heart disease, and stroke mortality by 11%, 25%, and 12%, respectively. 80) Alike, the JACC study (n=58,730) showed that the highest versus the lowest quintile of sodium intake was associated with increased risk of total CVD and stroke mortality by 42% and 55%, respectively. 81) In another study using the JACC study data (n=84,720), salt preference was associated with a 23% increase in stroke mortality.…”

Modifiable Risk Factors for Cardiovascular Disease in Korea and Japan

Author's summary Hypertension, diabetes, dyslipidemia, cigarette smoking, physical inactivity, obesity, and poor-quality diet are major modifiable risk factors for cardiovascular disease (CVD) in Korean and Japanese populations. In both Korea and Japan, physical inactivity exhibits the highest prevalence among the risk factors, followed by hypertension in Japan or obesity in Korea. Implementation of the primordial prevention strategies focused on the above-mentioned risk factors should be the priority of the health policymakers to tackle the growing burden of CVD in both countries.
