摘要
背景和目的研究方法和研究设计:横断面研究:研究对象为来自北京高校的512名18至31岁的健康青年。采用食物频率问卷(FFQ)和生物电阻抗分析仪(BIA)收集膳食摄入信息和身体成分:结果:膳食 Na 三分层组的脂肪相关指标和肌肉相关指标呈上升趋势(p 结论:膳食 Na 三分层组的脂肪相关指标和肌肉相关指标呈上升趋势:高膳食Na是大学生血脂分布异常的危险因素。高膳食钾可维持骨骼肌质量,降低肥胖风险。低膳食 Na 和高膳食 K 仍需在更多大学生中加强科普和实践。
Association between sodium and potassium intake levels and body compositions of Chinese college students.
Background and objectives: To investigate the relationship between sodium (Na) and potassium (K) nutritional condition and body compositions in youth aiming to give target population reasonable diet recommendations.
Methods and study design: The cross-sectional study was conducted involving 512 healthy youth aged 18 to 31 years from universities in Beijing. Food frequency questionnaire (FFQ) and bioelectrical impedance analyzer (BIA) were used to collect dietary intake information and body compositions.
Results: There was an increasing tendency in fat-related indicators and muscle-related indicators of the dietary Na tertile group (p <0.05). Additionally, Weight, body mass index (BMI), waist circumference (WC), and muscle-related indicators increased with the dietary K tertile group (p <0.05). Across increasing tertiles of dietary Na intake, the odds ratio (OR) was increased significantly (p < 0.05) in fat-related indicators. On the contrary, with the increased dietary Na intake, the OR decreased (p < 0.05) in appendicular skeletal muscle mass index (ASMI) and body lean mass. As tertiles of dietary K intake increased, the OR in both skeletal muscle mass index (SMMI) and lean mass index (LMI) decreased.
Conclusions: High dietary Na is a risk factor for abnormal lipid distribution in college students. High dietary K can maintain skeletal muscle mass and reduce the risk of obesity. Na in the diet has a greater impact on the body composition of young people than K. Low dietary Na and high dietary K still need to be strengthened in science popularization and practice among more college students.
期刊介绍:
The aims of the Asia Pacific Journal of Clinical Nutrition
(APJCN) are to publish high quality clinical nutrition relevant research findings which can build the capacity of
clinical nutritionists in the region and enhance the practice of human nutrition and related disciplines for health
promotion and disease prevention. APJCN will publish
original research reports, reviews, short communications
and case reports. News, book reviews and other items will
also be included. The acceptance criteria for all papers are
the quality and originality of the research and its significance to our readership. Except where otherwise stated,
manuscripts are peer-reviewed by at least two anonymous
reviewers and the Editor. The Editorial Board reserves the
right to refuse any material for publication and advises
that authors should retain copies of submitted manuscripts
and correspondence as material cannot be returned. Final
acceptance or rejection rests with the Editorial Board
