■乳制品是钙的营养来源,磷,蛋白质,和其他改善骨骼健康的营养素。然而,乳制品消费对日本人群骨生物标志物的影响尚不清楚.这项研究探讨了日本成年人乳制品消费与骨骼生物标志物之间的关系。
■这项横断面研究是作为青森岩崎健康促进项目的一部分进行的,日本。总的来说,1063名成年人被纳入分析。在当地居民的年度体检中,测量了骨转换标志物水平。使用定量超声技术计算了跟骨骨质评估指数(OSI)。使用食物频率问卷估计食物和营养素的饮食摄入量。使用乳制品消耗和骨生物标志物进行调整来建立线性回归模型。统计意义被认为是P<0.05。
■在多变量模型中,校正年龄和性别后,抗酒石酸酸性磷酸酶5b和甲状旁腺激素浓度与膳食乳制品摄入量呈负相关.羧化不足的骨钙蛋白,I型前胶原N端肽与骨碱性磷酸酶的比值,在调整的多变量模型中,OSI和OSI与乳制品消费直接相关。
■日本成年参与者的乳制品消费与骨转换生物标志物和OSI部分相关。习惯食用乳制品可能有助于维持骨骼健康的营养补充,包括营业额和结构。

UNASSIGNED: Dairy foods are nutritional sources of calcium, phosphorus, protein, and other nutrients that improve bone health. However, the effects of
dairy consumption on bone biomarkers in the Japanese population remain unclear. This study explored the association between
dairy consumption and bone biomarkers in Japanese adults.
UNASSIGNED: This cross-sectional study was conducted as part of the Iwaki Health Promotion Project in Aomori, Japan. In total, 1063 adults were included in the analysis. Bone turnover marker levels were measured in local citizens during their annual medical checkups. The calcaneus osteo sono assessment index (OSI) was calculated using a quantitative ultrasound technique. The dietary intake of foods and nutrients was estimated using a food frequency questionnaire. Linear regression models were established using
dairy consumption and bone biomarkers with adjustments. Statistic significance was considered by P < 0.05.
UNASSIGNED: In multivariate models, the tartrate-resistant acid phosphatase 5b and parathyroid hormone concentrations were inversely associated with dietary dairy consumption after adjusting for age and sex. The undercarboxylated osteocalcin, a procollagen type I N-terminal peptide to bone alkaline phosphatase ratio, and OSI were the directly associated with dairy consumption in multivariate models with adjustment.
UNASSIGNED: Dairy consumption is partially associated with bone turnover biomarkers and OSI in adult Japanese participants. Habitual consumption of
dairy foods may contribute to the nutritional supplementation for maintaining bone health, including turnover and structure.
