Dyslipidemia has been reported as a risk factor for incident hypertension in a few prospective studies, however, no study has specifically assessed different lipid measures including the lipid ratios, that is, total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) and triglycerides (TGs)/HDL-C as predictors of hypertension among Middle Eastern women with high prevalences of dyslipidemia and hypertension. The study population consisted of 2831 non-hypertensive women, aged ≥ 20 years. We measured lipoproteins, and calculated non-HDL-C and the lipid ratios. The risk-factor-adjusted odds ratios for incident hypertension were calculated for every 1 standard deviation (s.d.) change in TC, log-transformed TG, HDL-C, non-HDL-C, TC/HDL-C and log-transformed TG/HDL-C using multivariate logistic regression analysis. Over a mean follow-up of 6.4 years, 397 women developed hypertension. An increase of 1 s.d. in TG, TC/HDL-C and TG/HDL-C increased the risk of incident hypertension by 16, 19 and 18%, respectively, and 1 s.d. increase in HDL-C decreased the risk of hypertension by 14% in the multivariable model (all P ≤ 0.05). In models excluding women with diabetes and central or general obesity, TG, TG/HDL-C and TC/HDL-C remained as independent predictors of incident hypertension. In conclusion, dyslipidemia, using serum TG and TG/HDL-C, in particular, may be useful in identification of women at risk of hypertension, even in those without diabetes and central or general obesity.
血脂异常已被报道为少数前瞻性研究中高血压发生的危险因素,但尚无研究专门评估不同的脂质指标,包括总胆固醇(TC)/高密度脂蛋白胆固醇(HDL-C)和甘油三酯(TGs)/HDL-C,作为血脂异常和高血压高发的中东女性高血压的预测指标。研究人群由 2831 名年龄≥20 岁的非高血压女性组成。我们测量了脂蛋白,并计算了非高密度脂蛋白胆固醇和脂质比。使用多变量逻辑回归分析,计算了 TC、log 转化 TG、HDL-C、非高密度脂蛋白胆固醇、TC/HDL-C 和 log 转化 TG/HDL-C 每标准差(s.d.)变化的发生高血压的风险比。在平均 6.4 年的随访期间,397 名女性发生高血压。TG、TC/HDL-C 和 TG/HDL-C 每增加 1 s.d.,发生高血压的风险分别增加 16%、19%和 18%,HDL-C 每增加 1 s.d.,高血压的风险降低 14%(均 P≤0.05)。在排除糖尿病和中心或全身肥胖女性的模型中,TG、TG/HDL-C 和 TC/HDL-C 仍然是高血压发生的独立预测因子。总之,血脂异常,特别是使用血清 TG 和 TG/HDL-C,可以帮助识别有高血压风险的女性,即使在没有糖尿病和中心或全身肥胖的女性中也是如此。
