Background/Study context: The aim of the present work was to investigate the association of Waist-to-Height Ratio (WHtR) with Successful Aging (SA) status and compare it to classic anthropometric indices, among middle-aged and older individuals.Methods: Among various socio-demographic, clinical and lifestyle characteristics, height, weight, waist circumference (WC), Waist-to-Hip Ratio (WHR) and WHtR of the Greek participants, over 50 years old, enrolled in the ATTICA (n = 1,128) and the MEDIS (n = 2,221) in relation to SA; SA was evaluated using the validated Successful Aging Index (SAI, range 0-10) comprising of health-related, social, lifestyle, and clinical parameters.Results: WHtR was inversely associated with SAI with every 0.1-unit increase, lowering SAI by almost 0.5 units (b-coefficient±SE: -4.71 ± 0.26; 95%CI: -5.21, -4.20). Also, WHtR was more strongly associated with SAI (b = -0.352), surpassing the effect of age and sex (b = -0.347 and 0.11, respectively). With respect to the other anthropometric indices (weight, height, WC, WHR), WHtR exhibited the highest explanatory ability (Adjusted R2 = 0.345); the higher the adjusted R2 the higher explanatory ability.Conclusions: WHtR was revealed as the best determinant of successful aging, with respect to other anthropometric indices (weight, height, WC, WHR). The present findings are of significant public health importance for better understanding the role of body mass distribution on the aging process.

腰高比在预测老年人成功衰老方面优于经典人体测量学指标；对ATTICA和MEDIS流行病学研究的分析。

背景/研究背景：本研究的目的是调查中高身高与腰围身高比（WHtR）的关联，并将其与经典人体测量学指标进行比较。 ：在ATTICA中，年龄超过50岁的希腊参与者的身高，体重，腰围（WC），腰臀比（WHR）和WHtR在各种社会人口统计学，临床和生活方式特征中（n = 1,128）以及与SA有关的MEDIS（n = 2,221）；使用经过验证的成功老龄化指数（SAI，0-10范围）评估SA，包括健康相关，社会，生活方式和临床参数。结果：WHtR与SAI呈负相关，每增加0.1个单位，SAI降低近0.5个单位（b系数±SE：-4.71±0.26; 95％CI：-5.21，-4.20）。也，WHtR与SAI的相关性更强（b = -0.352），超过了年龄和性别的影响（分别为b = -0.347和0.11）。对于其他人体测量指标（体重，身高，WC，WHR），WHtR表现出最高的解释能力（调整后的R2 = 0.345）；结论：相对于其他人体测量指标（体重，身高，WC，WHR），WHtR被认为是成功衰老的最佳决定因素。本研究结果对于更好地了解体重分布在衰老过程中的作用具有重要的公共卫生意义。WHtR表现出最高的解释能力（调整后的R2 = 0.345）；结论：相对于其他人体测量指标（体重，身高，WC，WHR），WHtR被认为是成功衰老的最佳决定因素。本研究结果对于更好地了解体重分布在衰老过程中的作用具有重要的公共卫生意义。WHtR具有最高的解释能力（调整后的R2 = 0.345）；结论：相对于其他人体测量指标（体重，身高，WC，WHR），WHtR被认为是成功衰老的最佳决定因素。本研究结果对于更好地了解体重分布在衰老过程中的作用具有重要的公共卫生意义。
