“…The NHNS is a repeated cross-sectional survey conducted annually on a random sample of Japanese citizens in all 47 Japanese prefectures. The sample size was about 28,000 persons in 1975, 20,000 persons between 1976 and 1986, and gradually decreased to about 10,000 or less after 2000 [8,9]. In addition to answering a questionnaire, the respondents were invited to undergo a physical examination that included blood pressure measurements.…”

“…In addition to answering a questionnaire, the respondents were invited to undergo a physical examination that included blood pressure measurements. The response rate to the physical examination was reported as around 50 to 60% [9,10]. Stratified randomization by prefecture and household in a two-stage cluster sampling design is used for participant selection [8,9,11].…”

“…For the risk factor analysis, overweight and obese subjects were collapsed into one category of obese defined as 25 kg/m 2 BMI or more because Asian populations have been found to be at risk for metabolic disease at lower BMI values than Western populations [23]. In the NHNS, the dietary sodium intake is estimated retrospectively from self-reported food intake [9]. We converted sodium intake to salt intake by multiplication with a factor of 2.54 [24].…”

We investigated the prevalence and factors associated with hypertension, its treatment, and control using individual-level data from 300,249 respondents aged 20 years and older from the Japanese National Health and Nutrition Survey for the period of 1975–2010. We applied multivariate random effects logistic regression to assess associations between the risk factors and the prevalence of hypertension, the proportion of uncontrolled hypertension, and the proportions of respondents seeking treatment and controlling hypertension. The trends in the effect of the birth cohort on uncontrolled hypertension were also examined. Having hypertension was associated with being male, older, obese, drinking alcohol, and working in the primary industry and a higher proportion of middle-aged men than women were found being obese and drinking alcohol. Seeking treatment was associated with being older, obese, drinking alcohol, working in a primary industry and exercising. Controlling hypertension was associated with being younger, underweight and exercising. The proportion of individuals with uncontrolled hypertension declined for cohorts born in later years with a steeper decline for women than men. Raising awareness in the hypertensive population, especially among men, could help further reduce the prevalence of hypertension in Japan.

“…Participants aged from 1 year or older had measurements of height and weight and a dietary assessment and those aged 20 years or older additionally had blood tests and answered the question on household income. Detailed information regarding the NHNS were described elsewhere [21]. The NHNS is a survey conducted by the Japanese government based on the Health Promotion Law.…”

Though it has been reported that in Western developed countries socioeconomic status is associated with non-communicable diseases (NCD), there are sparse evidence from Japan, midst an income gap that has been pointed out in recent years. Therefore, we examined the presence or absence of NCD and the number of comorbidities according to household income in Japanese, using data from the National Health and Nutrition Survey of 2010. 1287 men and 1659 women aged 20 -79 years from households at 3 income levels (<2, 2 -5.9, ≥6 million yen) were analyzed. Participants completed questionnaires regarding whether they had been diagnosed with NCD, as well as undergoing clinical laboratory tests. Logistic regression analyses were used for statistical analysis with adjustment for age, gender, household size, and population of municipalities. The prevalences of participants with high, medium, and low income were 22.3%, 57.6%, and 20.2%, respectively. Participants with the lowest income had the highest odds of hypertension (OR [95% confidence interval or 3 NCD (hypertension, diabetes, and hypercholesterolemia) were 15.0% and 33.0% in high and low income levels, respectively. A low income could contribute to a high prevalence of NCD and large number of comorbidities among Japanese. Establishing a health policy in Japan is needed to enable an optimal health condition and lifestyle regardless of socioeconomic disparities.
