A study by the American Heart Association has shown that air pollution increases the risk of high blood pressure and heart disease in children.

A recent study published in the Journal of the Association states that the impact on children is of greater concern. Researchers have found that air pollution affects children who come to the hospital for heart problems.

The study also included children from countries including the United States, China, and European countries. According to the researcher, high blood pressure causes stress and heart problems in children.

They have claimed that the quality of this study is comparatively high as this conclusion has been drawn by integrating 14 studies on children. 

The study involved 350,000 children between the ages of five years, four months and 12 years, and seven months.

"We've done a careful analysis of the relationship between children's health and air pollution in past studies, and we've seen a direct and close relationship between the two," said Yao Lu (P.H.D.), a study author and professor at King's College London. 

He said that he had found a lot of evidence to clarify the relationship between the two sides. Long and short-term studies were also conducted. Similarly, the effects on morning, afternoon, evening, and night have also been analyzed. 

Past studies analyzed now were published on September 6, 2020.
