Cholesterol levels decrease in the West and rise in the East

For the first time, non-Western countries became the leaders in terms of blood cholesterol levels.

People in wealthy Western countries have significantly lower blood cholesterol levels than before. But in low-income countries, in particular in Asia, this dangerous figure continues to rise. The new report, which is published in Nature, shows a radical change in the "world map" of cardiovascular disease risk.

The study covers data on more than 100 million people worldwide. It includes information on the level of different fractions of cholesterol in the blood of residents of 200 countries for a period of 39 years - from 1980 to 2018.

Cholesterol is a substance that the body needs to function properly. But its excess or violation of the optimal ratio of fractions can lead to its deposition in the inner lining of blood vessels and the development of atherosclerosis. Atherosclerosis leads to narrowing of the arteries and the appearance of cardiovascular disease.

Work stress linked to risk of leg artery disease

Atherosclerosis of the vessels of the legs first leads to weakness and pain in the muscles, and over time it can even provoke amputation. Scientists have found that work stress can increase the risk of this condition.

High-density lipoproteins are called "good cholesterol" and have a protective effect against atherosclerosis. In a new review, the scientists focused on "bad cholesterol" - low and very low density lipoproteins - as well as total blood cholesterol. Their high rates are associated with the risk of angina pectoris, peripheral arterial lesions, heart attacks and strokes.

Over the period covered by the study, there have been radical changes. The highest levels of cholesterol levels were recorded for the first time outside the "Western world". Previously, the countries with the most dangerous numbers were Belgium, Finland, Norway, Sweden, Switzerland, and now they are Malaysia, the Philippines and Thailand.

In general, the situation has deteriorated in low and middle income countries, including in Southeast Asia. In 1980, China was among the countries with the lowest levels of "bad cholesterol" in the blood of residents. By 2018, he had not become the leader of the "anti-rating", but this country recorded one of the largest "leaps" in the increase in this indicator.

Cholesterol levels have dropped dramatically over 39 years in the wealthy countries of Northwest Europe, North America, Australasia. For example, in the rankings for men, the United States fell from 42nd to 108th.

According to the map provided by the authors, cholesterol levels among residents of Russia have also improved: they have decreased on average by 0.2-0.5 mmol / l -1 every 10 years since 1980.

The study authors point to the need for regulatory interventions in many countries to reduce the consumption of foods that are rich in saturated fat.

Professor Majid Ezzati believes that an important reason for lowering blood cholesterol levels in Western countries is the widespread use of statins, drugs that are prescribed to certain groups of patients to lower cholesterol levels. In poor countries, these drugs are used less.
