  1. BLF, Bama long-lived families; BNLF, Bama non-long-lived families; BNZLF, Bama non-Zhuang long-lived families; PLF, Pingguo long-lived families; PNLF, Pingguo non-long-lived families; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; TC, total cholesterol; TG, triglyceride; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol. The values of triglyceride, which were not normally distributed, were log-transformed for analysis but presented as untransformed raw values. The difference between BLF and other group was determined by the Wilcoxon-Mann–Whitney test. aP < 0.05 and bP < 0.01 in comparison with BLF; cP < 0.05 and dP < 0.01 in comparison between PNLF and BNLF.
