Abstract

Background/objectives: High-protein diets are increasingly used by young women for weight loss; however, concerns have been raised regarding their potential impact on bone health under insufficient calcium intake. This study investigated the associations between high-protein diet use for weight loss and bone status and diet quality among female college students.

Subjects/methods: In total, 260 female college students residing in Chungcheong, Korea, participated in this cross-sectional study. Data were collected using questionnaires, anthropometric measurements, 24-h dietary recall, and calcaneal ultrasound assessment. Participants were classified according to self-reported weight loss attempts during the past year into non-weight control (NWC; n = 108) and weight control (WC; n = 152) groups. The WC group was further subdivided into high-protein diet (HP-WC; n = 82) and non-high-protein diet (NHP-WC; n = 70) groups on the basis of high-protein diet practices.

Results: The mean body weight and body mass index (BMI) were significantly greater in the WC group than in the NWC group (P < 0.001 for both). Although calcium intake was significantly lower in the HP-WC group, protein intake exceeded the recommended level more frequently in this group (P < 0.05). A dietary diversity score less than 3 was more common in the HP-WC group (P < 0.05). Osteopenia prevalence was highest in the NWC group (64.8%), followed by the HP-WC group (50.0%) and the NHP-WC group (41.4%; P < 0.05). After adjustment for BMI and other confounding factors, the bone quality index and speed of sound values were significantly lower in the HP-WC group than in the NHP-WC group.

Conclusion: These findings suggest that high-protein weight-control practices may be associated with less favorable bone parameters among female college students during early adulthood, particularly in the context of lower calcium intake and reduced dietary diversity.

女大学生减肥的高蛋白饮食及其与骨骼状况和饮食质量的关系

背景/目的：高蛋白饮食越来越多地被年轻女性用于减肥；然而，在钙摄入不足的情况下，它们对骨骼健康的潜在影响引起了人们的关注。本研究调查了女大学生高蛋白饮食减肥与骨骼状况和饮食质量之间的关系。对象/方法：以居住在韩国忠清地区的260名女大学生为研究对象。通过问卷调查、人体测量、24小时饮食回忆和跟骨超声评估收集数据。参与者根据过去一年中自我报告的减肥尝试分为非体重控制组（NWC, n = 108）和体重控制组（WC, n = 152）。根据高蛋白饮食习惯，将WC组进一步分为高蛋白饮食组（HP-WC, n = 82）和非高蛋白饮食组（NHP-WC, n = 70）。结果：WC组的平均体重和身体质量指数（BMI）显著高于NWC组（P < 0.001）。HP-WC组钙摄取量显著低于推荐摄取量，蛋白质摄取量高于推荐摄取量（P < 0.05）。膳食多样性评分小于3分的多见于HP-WC组（P < 0.05）。骨质疏松发生率以NWC组最高（64.8%），HP-WC组次之（50.0%），nwp - wc组为41.4%,P < 0.05)。在校正BMI等混杂因素后，HP-WC组骨质量指数和声速值明显低于NHP-WC组。结论：这些发现表明，高蛋白体重控制习惯可能与成年早期女大学生的骨骼参数不佳有关，特别是在钙摄入量较低和饮食多样性减少的情况下。

期刊介绍： Nutrition Research and Practice (NRP) is an official journal, jointly published by the Korean Nutrition Society and the Korean Society of Community Nutrition since 2007. The journal had been published quarterly at the initial stage and has been published bimonthly since 2010. NRP aims to stimulate research and practice across diverse areas of human nutrition. The Journal publishes peer-reviewed original manuscripts on nutrition biochemistry and metabolism, community nutrition, nutrition and disease management, nutritional epidemiology, nutrition education, foodservice management in the following categories: Original Research Articles, Notes, Communications, and Reviews. Reviews will be received by the invitation of the editors only. Statements made and opinions expressed in the manuscripts published in this Journal represent the views of authors and do not necessarily reflect the opinion of the Societies.
