Research associates stressful neighborhoods with accelerated aging | News from Mexico and the world


Mexico.- The neighborhoods or neighborhoods considered stressful due to the aggression, pollution or turmoilare associated with a accelerated aging, with a more pronounced effect on women, according to research from the University of Glasgow.

According to the study published in the scientific journal "PLoS One"which combined research on population health and molecular biology, it was found that people who reported problems in their local area, such as theft, garbage and vandalism, had shorter telomeres.

O telomeres they are part of the DNA of people who give a measure of "miles on the clock" and their length represents a biological marker of age that is shortens with time, explained in a statement the academic institution.

The researchers analyzed data from 2,000 and 186 adults in the west of Scotland and measured stress factors of the neighborhoods at three times over a 12-year period and telomere duration at the end of the study.

The shorter length of telomeres already existed even after the analysis considered other factors associated with it, such as age, sex, social class, smoking, diet, weight, depression and physical condition.

Aging is more marked in women

Research has shown that chronic stressors in the neighborhoods were associated with accelerated aging, and the effect was more pronounced in women, explained Professor Anne Ellaway of the MRC / CSO's Social Sciences and Public Health Unit. University of Glasgow.

The aforementioned, the researcher mentioned, may be due to the fact that women spend more time in the local neighborhood or because men and women women process stressful environments differently and this can lead to different physiological responses.

Ellaway emphasized that improving damaged areas can counter this acceleration in aging.

While Professor Paul Shiels of the University Institute of Cancer Sciences mentioned that there is a substantial gap in health and longevity between the richest and most disadvantaged areas.

We now have more knowledge that the factors of this division are important, since People's local living environments can affect their health, as the study shows.

"The positive news is that neighborhood environments are potentially modifiable, and future efforts to improve underprivileged environments can be helpful in lessening the effects of how quickly people age," he said.
