“Our study highlights the importance of avoiding any tobacco environment in children, especially in those with a family history of rheumatoid arthritis,” said lead author Raphaele Seror, professor at the University Hospitals of South Paris, France.
The results of the study was presented at the Annual European Congress of Rheumatology (EULAR) 2017.
Further, in a separate analysis smoking was also associated with increased progression of structural damage to the spine in patients with ankylosing spondylitis — a painful, progressive and disabling form of arthritis caused by chronic inflammation affecting the spine and large joints.
Smoking led to the formation of new bony growths (known as syndesmophytes), the researchers said.
“Smoking constitutes a major risk factor not only for disease susceptibility but also disease severity in patients with AS,” said Servet Akar, professor from Izmir Katip Celebi University, Turkey.
“Rheumatologists should work hard to encourage their AS patients to quit smoking as this could have a major impact on future quality of life,” he added. (IANS)
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).
