Abstract

Background: Numerous studies have revealed the role of low dietary calcium-to-phosphorous ratio and low bone health. However, its possible role in visceral adiposity, skeletal muscle mass (SMM), and metabolic parameters has not been investigated before. Therefore, the aim of the current cross-sectional study was to evaluate the relation between dietary calcium-to-phosphorous ratio, metabolic risk factors, SMM, and visceral fat area (VFA) among physically active young individuals.

Methods: In the current study, the sample was composed of 391 healthy young individuals (e.g., 205 men and 186 women), aged between 20 and 35 years old, who were engaged in moderate physical activity for at least 4 hr per week and were recruited thorough cluster sampling from seven sport clubs. Anthropometric measurements were performed, and VFA and SMM index (SMI) were calculated. Biochemical assays were also performed by standard kits. Data were analyzed by one-way analysis of variance, analysis of co-variance, and multinomial logistic regression analysis using SPSS software.

Results: Those in the fourth quartile of dietary calcium-to-phosphorous ratio were more likely to have lower VFA (odds ratio [OR] = 0.98; 95% confidence interval [CI] [0.97, 0.99]; p = .023) and a nonsignificantly higher SMI (OR = 1.15; 95% CI [0.99, 1.34]; p = .058) after adjustment for the effects of confounders (e.g., age, gender, body mass index, physical activity level, dietary energy intake). Also, being in the third quartile of dietary calcium-to-phosphorous ratio made the subjects more susceptible to have lower insulin concentration (OR = 0.99; 95% CI [0.88, 0.93]; p = .026) in the adjusted model.

Conclusion: The findings of the current study revealed that a higher dietary calcium-to-phosphorous ratio in the habitual diet was negatively associated with visceral adiposity and insulin concentrations and higher SMM among physically active young individuals. Further interventional studies are required to confer causality that was not inferable in the current study because of cross-sectional design.

健康年轻人的膳食钙磷比例、代谢风险因素和脂质累积产物、骨骼肌质量和内脏脂肪面积。
背景:大量研究表明,低膳食钙磷比与骨骼健康有关。然而,其在内脏脂肪、骨骼肌质量(SMM)和代谢参数中可能发挥的作用尚未得到研究。因此,本横断面研究旨在评估膳食钙磷比、代谢风险因素、骨骼肌质量和内脏脂肪面积(VFA)之间的关系:在本次研究中,样本由 391 名健康的年轻人(如 205 名男性和 186 名女性)组成,他们的年龄在 20 岁至 35 岁之间,每周至少进行 4 小时的适度体育锻炼,并从 7 个体育俱乐部通过集群抽样的方式招募。研究人员对这些人进行了人体测量,并计算了VFA和SMM指数(SMI)。此外,还使用标准试剂盒进行了生化检测。使用 SPSS 软件对数据进行了单因素方差分析、共方差分析和多项式逻辑回归分析:结果:在对混杂因素(如年龄、性别、体重指数、体力活动水平、膳食能量摄入量)的影响进行调整后,膳食钙磷比处于第四四分位数的人更有可能具有较低的 VFA(几率比 [OR] = 0.98;95% 置信区间 [CI] [0.97, 0.99];p = .023)和非显著性较高的 SMI(OR = 1.15;95% CI [0.99, 1.34];p = .058)。此外,在调整模型中,膳食钙磷比处于第三四分位数的受试者更容易出现胰岛素浓度较低的情况(OR = 0.99; 95% CI [0.88, 0.93]; p = .026):本研究结果表明,习惯饮食中较高的膳食钙磷比与内脏脂肪和胰岛素浓度以及体力活动量较大的年轻人较高的 SMM 呈负相关。由于本研究采用的是横断面设计,因此无法推断出因果关系,需要进一步开展干预研究。
