Residents in disadvantaged communities may experience accelerated cellular aging due to their neighborhood's conditions, new research reveals. This environmental factor, alongside diet, sleep, and physical activity, is directly linked to health at a microscopic level, underscoring that environment matters as much as personal habits.
Who Is Affected
By 2030, one in six people globally will be over 60, yet this demographic shift means living longer without necessarily living healthier. Data from Nutrition Insight shows the gap between life expectancy and healthy life expectancy expanded by 13% to about nine years in 2019, indicating more years spent in "prolonged decay." New research addresses this challenge, revealing how neighborhood conditions measurably affect specific populations' aging.
Individuals in disadvantaged neighborhoods had higher levels of a specific gene marker for cellular aging in their blood, according to a New York University study of 1,215 American adults published in Social Science & Medicine and reported by Nautilus. This finding held true even after controlling for individual factors like income, health, and lifestyle choices. The gene, CDKN2A, arrests cell division, a process linked to "zombie cells" and age-related diseases.
