Abstract

Objective: To compare body mass index (BMI), waist circumference (WC) and WC-BMI in predicting elevated pulse pressure and to examine how these associations vary by age and sex.

Method: A cross-sectional analysis used data from the Peru Demographic and Health Survey (2018-2023). Poisson regression models with robust variance were employed to evaluate the association between anthropometric measures and elevated pulse pressure (≥ 50 mmHg), adjusting for sociodemographic and lifestyle factors.

Results: WC-BMI showed the most consistent and robust association with elevated pulse pressure compared to BMI and WC. The strength of the association was more significant in adults under 60 years and women. An attenuation of the effect was observed in individuals over 60 years for all anthropometric measures. WC-BMI presented a more linear and stable relationship across different population subgroups.

Conclussions: WC-BMI predicts elevated pulse pressure more precisely than BMI or WC alone. The attenuation of the effect in older adults and the differences by sex highlights the importance of considering demographic factors in evaluating cardiovascular risk.

[在预测脉压升高方面,腰围与BMI指数的比值优于BMI和腰围:秘鲁一项基于人群的分析]。
目的:比较体重指数(BMI)、腰围(WC)和WC-BMI对脉压升高的预测,并研究这些相关性在年龄和性别上的差异。方法:使用秘鲁人口与健康调查(2018-2023)的数据进行横断面分析。采用稳健方差泊松回归模型评估人体测量测量与脉压升高(≥50 mmHg)之间的关系,并对社会人口统计学和生活方式因素进行调整。结果:与BMI和WC相比,WC-BMI显示出与脉压升高最一致和最强大的关联。这种关联在60岁以下的成年人和女性中更为显著。在所有人体测量中,在60岁以上的个体中观察到这种效应的衰减。体重指数与体重指数在不同人群亚群间呈较稳定的线性关系。结论:WC-BMI比单独BMI或WC更准确地预测脉压升高。在老年人中的影响减弱和性别差异突出了在评估心血管风险时考虑人口因素的重要性。
