Life expectancy and risk of early death are always genetically related. However, a new study by scientists in Oxford’s population health sheds new light on the subject. Environmental factors can be seen to have the most impact on health and longevity. What should I look for?
An analysis carried out based on Biobank UK data covering almost half a million participants showed that environmental factors were responsible for 17%. The variability in the risk of death is much smaller than previously assumed, with genetic effects less than 2%.
Environment and genes. What’s more important?
Based on studies published in Nature Medicine, 25 important environmental factors have been identified that have a significant impact on aging and mortality. Of these, the most important role is:
Smoking – directly related to 21 different diseases, including coronary arteries, chronic obstructive pulmonary disease (COPD), lung cancer, brain stroke and type 2 diabetes, socioeconomic status – such as income, having an apartment or home, employment, etc. Factoral conditions affect the development and activity of 19 different diseases, depression, cardiovascular or type 2 diabetes physical – low levels increase the risk of hypertension, living conditions – access to health care, housing Conditions, levels of environmental pollution have a major impact on health and lifestyle.
Importantly, 23 factors can be altered through proper health and political activity. Studies also show that exposure to childhood negative factors in mothers who smoked during pregnancy can have long-term effects on health in the 30-80 years.

Some diseases are environmentally related, while others are genetic predispositions. for example:
Lung, heart and liver diseases are primarily determined by environmental factors dementia and breast cancer – indicating a stronger connection to genetics.

One of the key tools used in this study was SO-Called, based on the analysis of protein levels in the blood, and the aging clock. He allowed scientists to assess the body’s aging rate and identify factors that accelerate this process. This method was used not only in British studies but also in population analysis in China and Finland.

Research co-author Professor Cornelia Van Duzin emphasizes that these results should be an impulse to act to improve public health.
Professor Brian Williams, the leading scientific advisor to the British Heart Foundation, gave a similar opinion, and the results of the analysis highlight the urgent need for rules and actions from health organizations, creating a healthy lifestyle. We believe it will eliminate barriers that make it difficult.
