Approximately 1 billion adults worldwide have high blood pressure, which is continuously being monitored and studied. New research focuses on how wealth can affect those who suffer from high blood pressure.
A new study presented at the 84th Annual Scientific Meeting of the Japanese Circulation Society has found that working men with higher incomes are more likely to develop high blood pressure. Dr. Shingo Yanagiya of the Hokkaido University Graduate School of Medicine, who was involved in the study, points out that Japan alone has more than 10 million people with high blood pressure.
“High blood pressure is a lifestyle-related disease. As a physician seeing these patients, I wanted to know if risk varies with socioeconomic class, to help us focus our prevention efforts,” he said.
For the study, researchers examined the relationship between household income and high blood pressure in Japanese employees. A total of 12 workplaces were monitored, which included a total of 4,314 staff members (3,153 men and 1,161 women) with daytime jobs. All participants had normal blood pressure at the start of the study.
Four groups were monitored according to annual household income. These included less than 5 million yen (US$47,000), 5 million to 7.9 million ($74,000), 8 million to 9.9 million ($93,000), and 10 million or more Japanese yen per year. Over two years, researchers investigated the association between income and the development of high blood pressure.
Compared to men in the lowest income category, men in the highest income group were nearly twice as likely to develop high blood pressure. Participants in the 5 million to 7.9 million yen and 8 million to 9.9 million yen groups showed a 50 percent higher risk of developing high blood pressure compared to men with the lowest incomes. These findings were consistent, regardless of age, occupation, and other lifestyle factors.
Wealthy Women Not at Higher Risk
There was no significant link between income and blood pressure found in women. However, a lower risk of developing high blood pressure was found in those with higher household income.
“Some previous Japanese surveys have reported that higher household income is associated with more undesirable lifestyles in men, but not in women,” said Dr. Yanagiya. “Our study supports this: men, but not women, with higher household incomes were more likely to be obese and drink alcohol every day. Both behaviors are major risk factors for hypertension.”
High blood pressure is the leading global cause of premature death, accounting for almost 10 million deaths a year. Of those, 4.9 million deaths were due to ischemic heart disease, and 3.5 million were due to stroke. Researchers for the study concluded that men with high-paying daytime jobs are at particular risk for high blood pressure.
Men of all ages could significantly decrease their chance of heart attack or stroke by improving their health behaviors. This could include eating healthy, exercising, and controlling weight.
