Objective: In the present study, we detected a relationship between serum lipid/lipoprotein [serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL)-cholesterol and high-density lipoprotein (HDL)-cholesterol] and arterial blood pressure among Chinese nonagenarians/centenarian.
Methods: The present study analyzed data from the survey that was conducted on all residents aged 90 years or more in a district; there were 2,311,709 inhabitants in 2005. Arterial blood pressure included systolic blood pressure (SBP) and diastolic blood pressure (DBP).
Results: The subjects included in the statistical analysis were 217 men and 444 women. Subjects with hypertension (1.29 ± 0.74 vs 1.13 ± 0.45, t = 3.362, p = 0.001) or systolic hypertension (1.30 ± 0.74 vs 1.12 ± 0.45, t = 3.534, p < 0.0001) had higher levels of TG than those without. Subjects with abnormal levels of serum TG had higher SBP (145 ± 22 vs 139 ± 23, t = 2.223, p = 0.027). The Pearson correlation showed a significant relationship between SBP and serum TG levels (r = 0.088, p = 0.024). Unadjusted and adjusted multiple logistic regressions showed that hypertension or systolic hypertension was associated with an increased risk of abnormal of serum TG levels.
Conclusions: In summary, we found that among Chinese nonagenarians and centenarians, the levels of serum lipid/lipoprotein were associated with arterial blood pressure. Hypertriglyceridemia was associated with SBP.
