Background:
The pursuit of health and longevity is the eternal theme of humanity. Guangxi has a remarkable phenomenon of longevity in long-lived regions and ranks with the highest number of longevity villages in China, thus providing a natural advantage for health longevity research.
Methods:
In this study, we selected 117 natives of a longevity area in Guangxi, covering a large age range (38-118 years old) as subjects to measure peripheral leukocyte telomere length (LTL). Nineteen physical examination indicators and two inflammatory factor levels were measured.
Results:
Pearson's analysis revealed a significant negative correlation between age and LTL (r = -0.3694, p = 0.003), as well as alanine aminotransferase, albumin, total bilirubin, direct bilirubin, γ-glutamyltransferase, triglycerides, Interleukin-10, and tumor necrosis factor type-α. Systolic blood pressure and blood urea nitrogen were positively correlated with age. In addition, LTL decreased in people aged 38-89 years, and an upward trend was observed in people aged older than 90 years.
Conclusions:
Longevity individuals have characteristics, such as longer LTL, good hepatic function, and lower triglycerides and inflammation levels.
