High Prevalence of Prehypertension Is Associated with the Increased Body Mass Index in Community-Dwelling Japanese

Abstract

Hypertension and obesity are likely the most common disease in Japan. It has been reported that subjects with prehypertension (systolic blood pressure [SBP] 120-139 mmHg and/ or diastolic blood pressure [DBP] 80-89 mmHg) have also an increased risk of cardiovascular disease; however, only limited data are available on the prevalence of prehypertension and its association with body weight. We performed a cross-sectional study to examine whether the status of body weight was associated with prehypertension. Study participants aged 19 to 90 years [1,207 men aged 60 ± 15 (mean ± standard deviation) years and 1,634 women aged 63 ± 12 years] were randomly recruited for a survey at the community-based annual medical check-up. The prevalence of prehypertension was 27.3% in men and 23.9% in women. The levels of SBP and DBP increased, as body mass index (BMI) increased in both genders. In a multivariate-adjusted model, increasing BMI categories were positively associated with prehypertension. Especially in men, compared to participants with BMI of < 21.0 kg/m 2 (referent), the multivariate-odds ratio (95% CI) of prehypertension was 1.90 (1.17-3.09) in the 21.0-23.4 kg/m 2 group, 2.38 (1.31-4.34) in the 23.5-24.9 kg/m 2 group, and 3.79 (2.03-7.09) in the ≥ 25.0 kg/m 2 group. In conclusion, even subjects with mildly increased BMI (21.0-24.9 kg/m 2 ) had an increased risk of prehypertension in community-dwelling persons. It is time to pay more attention to excess bodyweight in preventing high blood pressure. risk factor; body mass index; prehypertension; hypertension; community-dwelling persons.

Prehypertension among young adult females in Dammam, Saudi Arabia

“…Regression analysis revealed that overweight/obesity was a significant predictor of prehypertension in our study. Similar findings were reported by several other studies [6,14,17,18,22,23]. The association between BP and weight is strong and linear, even in the normal range of BP and BMI [24].…”

“…Prehypertension was recognized to be more common among males than females, regardless of age [15][16][17][18]. Also, national studies conducted in Saudi Arabia revealed that hypertension was more common among males than females [4,5].…”

Prevalence of prehypertension and hypertension in a Chinese rural area from 1991 to 2007

“…14 However, the prevalence of prehypertension in 2002 in our study was higher than that (from 23.9 to 44.3%) in other studies conducted in China, Israel, the United States and Japan. [21][22][23][24] Although variations in geography, race, age and lifestyle in different studies may partially account for the differences in observed results, 12,24 the rapid increase in the prevalence of prehypertension from 1991 to 2002 in our study may be related to the more stressful workload, high-calorie and salty food, reduced physical activity and more common overweight and obesity in the rural area during the past two decades. 25,26 Although the term prehypertension is still in dispute, recent studies have found a positive correlation between prehypertension and major cardiovascular diseases in the Chinese population, 14,15 indicating that detection of prehypertension may have important clinical significance.…”

Prehypertension and hypertension among young Indonesian adults at a primary health care in a rural area

“…19,27,29,30,36,37 Pang et al 35 specifically found associations between BMI and elevated blood pressure. We found that overweight and obese subjects were more likely to develop prehypertension and hypertension, since overweight and obesity were more prevalent in prehypertensive and hypertensive than in normotensive groups.…”
