Low socioeconomic status (SES) is associated with accelerated epigenetic aging, specifically an increase in biological age of approximately 1 year compared to high SES, independent of major lifestyle risk factors.
Social environment impacts biological aging. While you cannot change your past, improving your social and economic conditions, especially in early life, may help slow down biological aging processes. Focus on reducing chronic stress and building supportive social networks as these are key components of socioeconomic well-being.
Low SES was associated with greater AA (β = 0.99 years; 95% CI 0.39,1.59; p = 0.002; comparing extreme categories).
Why this rating

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
