Living with a smoker after age 20 is associated with a 15 per cent greater risk of developing high blood pressure, warn researchers, adding that avoiding smoky environments can reduce the risk of hypertension.

Passive smoking at home or work was linked with a 13 per cent increased risk of hypertension.

Exposure to passive smoking for 10 years or more was related to a 17 per cent increased risk of hypertension and men and women were equally affected, said the researchers at “EuroHeartCare 2019”, a scientific congress of the European Society of Cardiology, in Milan, Italy on Friday.

“Avoid exposure to secondhand smoke regardless of whether the smoker is still in the room,” said study author Professor Byung Jin Kim from Sungkyunkwan University, Seoul, Korea.

“Our study in non-smokers shows that the risk of high blood pressure (hypertension) is higher with longer duration of passive smoking — but even the lowest amounts are dangerous,” Kim added.

This is the first large study to assess the association between secondhand smoke and hypertension in never-smokers verified by urinary levels of cotinine, the principal metabolite of nicotine.

It included 131,739 never-smokers, one-third men, and an average age of 35 years.

Participants with hypertension were significantly more likely to be exposed to secondhand smoke at home or work (27.9 per cent) than those with normal blood pressure (22.6 per cent).

Hypertension was significantly more common in people exposed to passive smoke at home or work (7.2 per cent) compared to no exposure (5.5 per cent).

“The results suggest that it is necessary to keep completely away from secondhand smoke, not just reduce exposure, to protect against hypertension,” said Professor Kim. (IANS)

People who are exposed to high pollution levels are at significantly higher risk of suffering from hypertension, metabolic syndrome and heart diseases, says a new study.

In the study, published in Journal of Public Health, the researchers investigated the associations between a long-term exposure to ambient air pollution and residential distance to green spaces and major roads with the development of hypertension and metabolic syndrome components such as a high triglyceride level, reduced high-density lipoprotein cholesterol, higher blood glucose, and obesity.

Hypertension and metabolic syndrome are important causes of cardiovascular diseases, the researchers said. The study’s findings showed that air pollution levels above the median are associated with a higher risk of reduced high density lipoprotein.

Traffic-related exposure was associated with the incidence of hypertension, higher triglyceride level and reduced high-density lipoprotein cholesterol. However, the negative impact of traffic air pollutants was observed only in the participants who lived in multifamily buildings.

The researchers also found positive effects of the natural environment, and have emphasized the positive impact of such spaces on cardiovascular health.

“Our research results enable us to say that we should regulate as much as possible the living space for one person in multifamily houses, improve the noise insulation of apartments, and promote the development of green spaces in multifamily houses” said study’s lead author Agn Brazien. (IANS)
