A study, presented at the 84th Annual Scientific Meeting of the Japanese Circulation Society (JCS 2020), has revealed that rich men are more prone to developing hypertention.
JCS 2020 is taking place online from 27 July to 2 August in conjunction with the Asian Pacific Society of Cardiology Congress 2020 (APSC 2020).
Joint scientific sessions are being held by the European Society of Cardiology (ESC) and JCS as part of the ESC Global Activities programme.
The study has been presented by researchers from the Hokkaido University Graduate School of Medicine, Sapporo, Japan. The study has advised men with higher incomes to improve their lifestyles to prevent high blood pressure.
The study examined the relationship between household income and high blood pressure in Japanese employees. A total of 4,314 staff (3,153 men and 1,161 women) with daytime jobs and normal blood pressure were enrolled in 2012 from 12 workplaces.

Workers were divided into four groups according to annual household income: less than 5 million, 5 to 7.9 million, 8 to 9.9 million, and 10 million or more Japanese yen per year. The researchers investigated the association between income and developing high blood pressure over a two-year period.
Compared to men in the lowest income category, men in the highest income group were nearly twice as likely to develop high blood pressure. Men in the 5 to 7.9 million and 8 to 9.9 million groups had a 50% higher risk of developing high blood pressure compared to men with the lowest incomes, although the positive association did not reach statistical significance in the 8 to 9.9 million group.

The findings were consistent regardless of age, and were independent of baseline blood pressure, worksite, occupation, number of family members, and smoking. The relationships were slightly weakened after accounting for alcohol consumption and body mass index (BMI; kg/m2), both of which were higher for men in the higher income groups.
In women, there was no significant link between income and blood pressure. However, women with higher household income tended to have a lower risk of developing high blood pressure.
