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)

Indian researchers have found that patients with hypertension and Type 2 diabetes who consumed a high Fibre diet witnessed an improvement in their blood pressure, cholesterol and fasting glucose.

For the study, the research team from Care Well Heart and Super Specialty Hospital in Amritsar, investigated the relationship between a high fibre diet and its impact on cardiovascular disease risk factors.

“Comprehensive evaluation of etiological effects of dietary factors on cardiometabolic outcomes, their quantitative effects and corresponding optimal intakes are well-established,” said the study’s lead author Rohit Kapoor.

According to guidelines from the National Institute of Nutrition and the Indian Council of Medical Research, the recommended dietary allowance (RDA) for dietary fibre is 40gm/2000kcal.

Patients in this study had Type 2 diabetes and a calorie intake of 1,200-1,500kcal, causing their RDA for fibre to be 24-30gm.

The fibre intake of these patients was increased up to 20 to 25 per cent from the recommended allowances for them to be consuming a high fibre diet.

The study tracked 200 participants’ fibre intake for six months and included check-ups at the start of the study, three months and six months.

Participants were provided with diet prescriptions, which included detailed lists of different food groups with portion sizes in regional languages.

The researchers tracked participants’ fibre intake several ways, including having patients send photos of their meals on WhatsApp, which not only helped in knowing their fibre intake but also helped approximate portion sizes, and telephone calls three times a week during which detailed dietary recall was taken.

Participants on a high fibre diet experienced significant improvement in several cardiovascular risk factors, including a nine per cent reduction in serum cholesterol, 23 per cent reduction in triglycerides, 15 per cent reduction of systolic blood pressure and a 28 per cent reduction of fasting glucose.
