There have only been a few studies on the role of mineral intake in tooth loss. We investigated the association between mineral intake and the prevalence of tooth loss in Japan. We used the baseline data on 1002 pregnant women who were enrolled in the Osaka Maternal and Child Health Study between November 2001 and March 2003. Tooth loss was defined as the previous extraction of one or more teeth. Nutrient intake was assessed by a validated diet history questionnaire. Prevalence odds ratios and confidence intervals were estimated by applying a multiple logistic regression model. The adjusted odds ratio upon comparison of the highest quartile with the lowest quartile of magnesium intake was 0.64 (95% confidence interval, 0.42-0.99), showing a tendency for an inverse dose-response relationship (p for linear trend = 0.05). There were no associations between the level of consumption of calcium, phosphate, iron, zinc, or copper and tooth loss. The present findings suggest that intake of magnesium is related to reduced prevalence of tooth loss among young Japanese women.
关于矿物质摄入在牙齿脱落方面的作用，仅有少数研究。我们调查了日本矿物质摄入与牙齿脱落患病率之间的关联。我们使用了2001年11月至2003年3月期间参加大阪母婴健康研究的1002名孕妇的基线数据。牙齿脱落定义为先前拔除一颗或多颗牙齿。通过一份经过验证的饮食史问卷评估营养摄入情况。应用多元逻辑回归模型估计患病率比值比和置信区间。镁摄入量最高四分位数与最低四分位数相比，调整后的比值比为0.64（95%置信区间，0.42 - 0.99），呈现出剂量反应反比关系的趋势（线性趋势p值 = 0.05）。钙、磷、铁、锌或铜的消费水平与牙齿脱落之间无关联。目前的研究结果表明，镁的摄入与日本年轻女性牙齿脱落患病率降低有关。
