Abstract

Objective: Dietary diversity and eating behaviour are recognised as factors influencing body composition; however, their association with fat-free mass index and body fat mass index remains unclear.

Methods: This cross-sectional study analysed the relationships among body composition indices (BMI, FFMI, BFMI), self-reported eating speed, and dietary diversity in 10 644 healthy adults aged 18-64 years (4419 women and 6225 men; mean age 41.9 years) who visited hospitals for health checkups.

Results: The dietary variety score showed a positive association with muscle mass in men and a significant negative association with body fat mass index in women (fat-free mass index: β = 0.03, 95% confidence interval: 0.01 to 0.05, p = 0.04; body fat mass index: β = -0.07, 95% confidence interval: -0.15 to -0.01, p < 0.01). Regarding eating speed, a consistent trend was observed in both sexes: the fast-eating group showed significantly higher body mass index, fat-free mass index, and body fat mass index values (p < 0.01), whereas the slow-eating group had lower values.

Conclusions: These associations were more pronounced in men than in women. Both dietary diversity and eating speed were associated with body composition indices, with notable sex-related differences. These findings suggest that dietary behaviour and diversity may influence body composition.

成年人进食速度、饮食多样性和无脂肪质量指数之间的关系。

目的：饮食多样性和饮食行为被认为是影响身体组成的因素；然而，它们与无脂质量指数和体脂质量指数的关系尚不清楚。方法：本横断面研究分析了10 644名18-64岁健康成人（女性4419人，男性6225人，平均年龄41.9岁）到医院进行健康检查的身体成分指数（BMI、FFMI、BFMI）、自述进食速度和饮食多样性的关系。结果：膳食多样性评分与男性肌肉质量呈正相关，与女性体脂质量指数呈显著负相关（无脂质量指数：β = 0.03, 95%可信区间：0.01 ~ 0.05,p = 0.04；体脂质量指数：β = -0.07, 95%可信区间：-0.15 ~ -0.01,p）。结论：这些相关性在男性中比女性更明显。饮食多样性和进食速度均与体成分指数相关，且性别差异显著。这些发现表明，饮食行为和多样性可能会影响身体组成。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
