CHENNAI: According to a study published in the Lancet medical journal, air pollution increases the risk of heart disease in middle and low income countries, such as China and India.
The study – "Modifiable risk factors, cardiovascular disease and mortality in 21 high-income, middle and low-income countries (in the pure state): a prospective cohort" – indicates that hypertension, the cholesterol, air pollution, diabetes and poor diet are the main cardiovascular risk factors. the disease among low-income groups, while cholesterol, tobacco, hypertension, diabetes and abdominal obesity are the main factors of high-income groups.
Responding to the findings of the study, Dr. V Mohan, a Chennai-based diabetologist, emphasized the importance of fighting air pollution. "Right now, we have limited access to treatment and adherence to treatment. But more than anything else, air pollution aggravates health problems. This requires urgent attention, "he said.
"Cancer can become the leading cause of death"
Another study published in Lancet indicates that heart disease kills most people around the world, but in high-income countries, cancer deaths are twice as common as heart disease. The study documented the prevalence of common diseases and death rates in countries.
The study, presented at the congress of the European Society of Cardiology, stems from the prospective study on rural urban epidemiology (PURE) conducted by the Institute for Health Research of the Population (PHRI) from McMaster University and Hamilton Health Sciences in Hamilton, Canada. Scientists studied more than 162,500 adults aged 35 to 70 from 21 countries and followed them for nearly 10 years.
The results showed that for six cancer deaths, there were four deaths due to heart disease in high-income countries such as Canada, Sweden, Saudi Arabia and the United Arab Emirates. In middle-income countries (Argentina, Brazil, Chile, China, Malaysia and the Philippines), there was one cardiovascular death for each cancer death. In low-income groups such as Bangladesh, India, Pakistan, Tanzania, and Zimbabwe, there were three cardiac deaths for each death caused by cancer.
The study, according to lead investigator Salim Yusuf, also executive director of PHRI and a professor of medicine at McMaster University, points to a transition of the leading causes of death among people of middle age. "As CVD decreases in many countries due to prevention and treatment, cancer mortality will likely become the leading cause of death worldwide in the future. High mortality in the poorest countries is not due to a higher risk factor burden, but probably to other factors, including lower quality and lower health care, "he said. he declared.
