Abstract

Several small-scale trials indicate a positive correlation between dietary creatine intake and fat-free mass in the pediatric population; whether this connection occurs at the population-wide level remains currently unknown. The main purpose of this cross-sectional study was to calculate the amount of creatine consumed through a regular diet among U.S. boys and girls aged 8 to 19 years, and investigate the link between creatine consumption and dual-energy X-ray absorptiometry (DXA)-derived body composition indices in this population. Data were obtained from the National Health and Nutrition Examination Survey 2017-2018 round, with dietary information and whole-body DXA body composition measures extracted for respondents aged 8 to 19 years (1273 participants, 649 boys and 624 girls). Individual values for total grams of creatine consumed per day for each participant were computed using the average amount of creatine (3.88 g/kg) across all creatine-containing foods. The primary exposure was the mean daily intake of creatine; the primary and secondary outcomes comprised lean mass excluding bone mineral content (BMC), and bone mineral density, BMC, lean mass including BMC, fat mass, and percent body fat, respectively. The average intake of creatine across the sample was 0.65 ± 0.72 g/day (95% CI, from 0.61 to 0.69). Creatine positively correlated with lean mass (excluding BMC) and BMC across the whole sample (r = .18 and .20, respectively; P < .001); a significant negative correlation was found between creatine intake and percent body fat (r = -.09; P = .001). The higher intake of creatine was associated with higher lean mass in girls and higher BMC in boys, while taking more creatine corresponded to less body fat for both genders (P < .05). Our findings indicate a significant correlation between dietary creatine and DXA-derived body composition biomarkers in a nationally representative cohort of U.S. youth. These results justify further research of creatine's role in modifying body morphology in the pediatric population, taking into account the age and sex specific traits.

8至19岁男孩和女孩的食物肌酸和dda来源的身体成分。
几项小规模试验表明,在儿科人群中,膳食肌酸摄入量与无脂量呈正相关;目前尚不清楚这种联系是否会在整个人群中发生。本横断面研究的主要目的是计算美国8至19岁男孩和女孩通过常规饮食消耗的肌酸量,并调查该人群中肌酸消耗与双能x线吸收仪(DXA)衍生的身体成分指数之间的联系。数据来自2017-2018年全国健康与营养检查调查,提取了8至19岁受访者(1273名参与者,649名男孩和624名女孩)的饮食信息和全身DXA身体成分测量。每个参与者每天消耗的肌酸总克数的个体值使用所有含肌酸食物的平均肌酸量(3.88 g/kg)来计算。主要暴露量为每日平均肌酸摄入量;主要和次要结果分别包括不包括骨矿物质含量(BMC)的瘦体重、骨矿物质密度、BMC、包括BMC的瘦体重、脂肪量和体脂百分比。整个样本的平均肌酸摄入量为0.65±0.72 g/天(95% CI,从0.61到0.69)。肌酸与瘦体重(不包括BMC)和整个样本的BMC呈正相关(r =。分别为18和0.20;P r = - 0.09;p = .001)。较高的肌酸摄入量与女孩较高的瘦质量和男孩较高的BMC有关,而摄入更多的肌酸则与男女较少的体脂有关(P

期刊介绍: Nutrition and Metabolic Insights is a peer-reviewed, open-access online journal focusing on all aspects of nutrition and metabolism. This encompasses nutrition, including the biochemistry of metabolism, exercise and associated physical processes and also includes clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes. It includes research at the molecular, cellular and organismal levels. This journal welcomes new manuscripts for peer review on the following topics: Nutrition, including the biochemistry of metabolism, Exercise and associated physical processes, Clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes, Research at the molecular, cellular and organismal levels, Other areas of interest include gene-nutrient interactions, the effects of hormones, models of metabolic function, macronutrient interactions, outcomes of changes in diet, and pathophysiology.
