Abstract：
UNASSIGNED: Bone mineral density (BMD) and body composition play an important role in maintaining metabolic health and physical functioning. Plant-based diets (PBDs) are known to be lower in protein and calcium, which can impact BMD and body composition. This study aimed to investigate the relationship between various PBDs compared to regular meat diet and whole-body BMD, body composition, and weight status.
UNASSIGNED: A cross-sectional study was conducted with adults (n = 240) aged 30-75 years, who habitually followed dietary patterns: vegan, lacto-vegetarian, pesco-vegetarian, semi-vegetarian, or regular meat eater (48 per group). Parameters were measured using dual-energy x-ray absorptiometry (DXA), and multivariable regression analyses were used to adjust for lifestyle confounders, socioeconomic factors, and BMI.
UNASSIGNED: After adjustments, whole-body BMD and body composition were not significantly different between those following PBDs and regular meat diets, except for lacto-ovo vegetarians, who had significantly lower lean mass by -1.46 kg (CI: -2.78, -0.13). Moreover, lacto-ovo vegetarians had a significantly lower T-score by -0.41 SD (CI: -0.81, -0.01) compared to regular meat eaters. Waist circumference was significantly lower in individuals adhering to a PBD compared to a regular meat diet: vegans by -4.67 cm (CI: -8.10, -1.24), lacto-ovo vegetarians by -3.92 cm (CI: -6.60, -1.23), pesco-vegetarians by -3.24 cm (CI: -6.09, -0.39), and semi-vegetarians by -5.18 cm (CI: -7.79, -2.57). There were no significant differences in lean mass (%), fat mass (% and total), android/gynoid measures, body weight, or BMI across dietary patterns. All dietary patterns met the recommended dietary intake for calcium and protein, and 25-hydroxy-vitamin D status was comparable across groups.
UNASSIGNED: This cross-sectional study found that adhering to a PBD characterized by varying degrees of dairy and meat restriction is not associated with meaningful changes in BMD or body composition, provided that the dietary patterns are planned appropriately with adequate levels of calcium and protein.

摘要：
■骨矿物质密度（BMD）和身体成分在维持代谢健康和身体机能中起着重要作用。已知植物性饮食（PBD）的蛋白质和钙含量较低，会影响BMD和身体成分。本研究旨在探讨各种PBD与常规肉类饮食和全身BMD之间的关系。身体成分,和体重状态。
■对30-75岁的成年人（n=240）进行了横断面研究，习惯性地遵循饮食模式:素食主义者，素食主义者，pesco-素食主义者,半素食,或常规肉食者（每组48人）。使用双能X射线吸收法（DXA）测量参数，多元回归分析用于调整生活方式混杂因素，社会经济因素,BMI。
■调整后，全身BMD和身体成分在PBD和常规肉类饮食之间没有显着差异，除了乳卵素食者，瘦体重显著降低-1.46kg（CI：-2.78，-0.13）。此外，与普通肉食者相比，乳卵素食者的T评分显着降低-0.41SD（CI：-0.81，-0.01）。与常规肉类饮食相比，坚持PBD的个体的腰围显着降低：素食者-4.67厘米（CI：-8.10，-1.24），乳卵素食者-3.92厘米（CI：-6.60，-1.23），pesco-素食者-3.24厘米（CI：-6.09，-0.39），和半素食者-5.18厘米（CI：-7.79，-2.57）。瘦肉质量(%)没有显著差异，脂肪量（%和总计），android/gynoid措施，体重,或不同饮食模式的BMI。所有饮食模式都符合钙和蛋白质的推荐饮食摄入量，25-羟基维生素D状态在各组间具有可比性.
■这项横断面研究发现，坚持以不同程度的乳制品和肉类限制为特征的PBD与BMD或身体成分的有意义变化无关，前提是饮食模式计划得当，钙和蛋白质含量充足。
