Air purifiers a good way to stay away from major respiratory diseases: Doctors

New Delhi: In order to prevent respiratory diseases caused by indoor air pollution, doctors suggest people to install air purifiers at home which can prove helpful in preventing them.

According to doctors, air purifiers are becoming more reliable for people in cities because pollutants released indoors were 1,000 times more likely to reach the lungs than pollutants released outdoors.

More than 5.5 million people worldwide die prematurely every year due to household and outdoor air pollution, and India and China together account for 55 percent of these deaths, research has found.

Air pollution has come up as one of the major health challenges of modern Indian cities. With increasing respiratory problems, it is now important to know about pollutants, and their health hazards.

“Air purifiers are emerging as a good way to stay away from major respiratory diseases caused by indoor air pollution,” said Raj Kumar, head of respiratory allergy and applied immunology at Vallabhbhai Patel Chest Institute.

He said recent studies have revealed the strong link between major respiratory and lung diseases due to air pollution, which clearly indicated the need to cut down the sources of indoor air pollution.

With the World Health Organization (WHO) declaring air quality of Indian metropolitan cities as the worst in the world, healthcare professionals are registering a sharp rise in respiratory problems, especially in immuno-compromised population like children, elderly and people with health issues or malnutrition.

Himanshu Garg, head of respiratory and critical care at Artemis Hospital, said: “In India, we have a long-standing tradition of burning of ‘incense sticks’ and ‘dhoop’ that could increase the concentration of particulate matter (PM) by about 15 times more than the permitted levels.”

“Smoke emitted by these releases harmful pollutants. Along with this, smoke from tobacco and cooking and dust from carpets, furniture and curtains, etc. add to the indoor air pollution.”

“Health problems caused can be reduced by installing air purifiers, which bring down the percentage of pollutants in the air,” said Garg. (IANS, Image source: austinair.com)

Children of Mothers With Diabetes Are Likely To Suffer From Heart Diseases, Says Study

The researchers also found higher rates for specific types of CVD children of mothers with diabetes

Children of mothers with diabetes have increased rates of early onset cardiovascular disease or CVD (conditions affecting the heart or blood vessels) from childhood up to the age of 40, the researchers have warned.

The increased rates were more pronounced among children of mothers with a history of CVD or diabetic complications, said the study published in the journal The BMJ.

“Our study provides evidence that children of mothers with diabetes, especially those with a history of CVD or with diabetic complications, had increased rates of early onset CVD throughout the early decades of life,” said study researchers from Aarhus University in Denmark.

If this association is shown to be causal, preventing, screening, and treating diabetes in women of childbearing age could be important not only for improving the health of the women but also for reducing long term risks of CVD in their offspring, the researchers added

The number of women diagnosed with diabetes before or during pregnancy has increased globally, and children of these women are more likely to have risk factors for future CVD, such as high blood pressure and high blood sugar levels. It is unclear, however, whether or to what extent exposure to diabetes in the womb increases the risk of developing CVD in offspring over a lifetime.

So an international team of researchers set out to evaluate associations between diabetes diagnosed before or during pregnancy and early onset CVD in children during their first four decades of life. They base their findings on national registry data for over 2.4 million children born without congenital heart disease in Denmark from 1977 to 2016.

Diabetes was categorised as pregestational (before pregnancy) or gestational (during pregnancy) and women with diabetic complications were identified.

Other potentially influential factors, such as mother’s age, education, lifestyle and medical history were also taken into account. During up to 40 years of follow-up, children of mothers with diabetes had a 29 per cent increased overall rate of early onset CVD compared with children of mothers who did not have diabetes (cumulative risks: 17.8 per cent vs 13.1 per cent ).

The researchers also found higher rates for specific types of CVD children of mothers with diabetes, particularly heart failure (45 per cent), hypertensive disease (78 per cent), deep vein thrombosis (82 per cent), and pulmonary embolism (91 per cent).

Increased rates were seen in each age group in childhood (before 20 years of age) and early adulthood (from 20 to 40 years of age), regardless of the type of diabetes they were exposed to (pregestational or gestational) and rates were similar for both type 1 and type 2 diabetes, the study said.
