Abstract

Background: Magnesium is critical for musculoskeletal health. Hypertensive patients are at high risk for magnesium deficiency and muscle loss. This study aimed to explore the association between magnesium intake and muscle mass in patients with hypertension.

Methods: In this population-based cross-sectional study, 10,279 U.S. hypertensive adults aged 20 years or older were derived from the National Health and Nutrition Examination Survey in 1999-2006 and 2011-2018. Magnesium (Mg) intake from diet and supplements was assessed using 24-hour diet recalls. Muscle mass was evaluated by appendicular skeletal muscle mass index (ASMI, total ASM in kilograms [kg] divided by square of height in meters [m2]). The association of Mg intake with ASMI was estimated using weighted multivariable-adjusted linear regression models and restricted cubic splines.

Results: Dose-response analyses showed a positive linear correlation between dietary Mg intake and ASMI. Every additional 100 mg/day in dietary Mg was associated with 0.04 kg/m2 (95% confidence interval [CI] 0.02-0.06 kg/m2) higher ASMI. The ASMI in participants who met the recommended dietary allowance (RDA) for dietary Mg was 0.10 kg/m2 (95% CI 0.04-0.16 kg/m2) higher than those whose dietary Mg was below estimated average requirement (EAR). However, the relationship of Mg intake from supplements with ASMI was not identified.

Conclusion: Higher level of dietary Mg intake rather than Mg supplements was associated with more muscle mass in U.S. adults with hypertension, which highlights the importance of meeting the recommended levels for dietary Mg intake.

高血压人群膳食镁摄入量与肌肉质量之间的关系:来自全国健康与营养调查的证据。
背景:镁对肌肉骨骼健康至关重要。高血压患者是镁缺乏和肌肉流失的高危人群。本研究旨在探讨高血压患者镁摄入量与肌肉质量之间的关系:在这项基于人群的横断面研究中,10279 名年龄在 20 岁或以上的美国高血压成人来自 1999-2006 年和 2011-2018 年的国家健康与营养调查。镁(Mg)的摄入量通过 24 小时饮食回顾进行评估。肌肉质量通过骨骼肌质量指数(ASMI,以公斤为单位的骨骼肌总量除以以米为单位的身高的平方[m2])进行评估。采用加权多变量调整线性回归模型和限制性三次样条来估计镁摄入量与 ASMI 的关系:结果:剂量-反应分析表明,膳食镁摄入量与 ASMI 呈正线性关系。膳食镁摄入量每增加 100 毫克/天,ASMI 就会增加 0.04 kg/m2(95% 置信区间 [CI] 0.02-0.06 kg/m2)。与膳食镁摄入量低于估计平均需要量(EAR)的人相比,膳食镁摄入量达到建议膳食摄入量(RDA)的人的ASMI要高出0.10 kg/m2(95% CI 0.04-0.16 kg/m2)。然而,从补充剂中摄入的镁与 ASMI 之间的关系尚未确定:结论:较高水平的膳食镁摄入量(而非镁补充剂)与美国成人高血压患者肌肉质量的增加有关,这凸显了膳食镁摄入量达到推荐水平的重要性。

期刊介绍: Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
