To explore the interrelationship between type and timing of dietary acid intake and tooth wear among American adults.
This study used data from 3,586 adults, aged 18 years and older, who participated in the National Health and Nutrition Examination Survey (NHANES) 2003-04. Information on four types of acidic food and beverages (fruits, fruit juices, alcoholic drinks, and soft drinks) and timing of consumption (meals versus snacks, defined according to percentage of total energy intake, self-reported eating occasion, and time of day) was extracted from two 24-hour dietary recalls. The association of the type and timing of dietary acid intake with the number of surfaces with moderate-to-severe tooth wear was assessed in Hurdle models to account for the excess zero counts and over-dispersion. Models were adjusted for socio-demographic factors, acid reflux medication, and dental insurance coverage.
The daily intake of soft drinks was associated with tooth wear, while those of fruits, fruit juices, and alcoholic drinks were not. The consumption of soft drinks with meals was the only factor consistently associated with tooth wear, irrespective of the method used to define meals versus snacks. The above associations were found with the number of surfaces with tooth wear (among those with the condition), but not with the odds of having tooth wear (among all participants).
The consumption of soft drinks with meals was associated with moderate-to-severe tooth wear among American adults. Other acidic foods and beverages were not associated with tooth wear, regardless of their timing of consumption.
探讨美国成年人饮食酸摄入的类型和时间与牙齿磨损之间的相互关系。
本研究使用了 3586 名年龄在 18 岁及以上的成年人的数据，这些人参加了 2003-04 年的国家健康和营养调查（NHANES）。从两份 24 小时膳食回忆中提取了四种酸性食物和饮料（水果、果汁、酒精饮料和软饮料）以及消费时间（正餐与零食，根据总能量摄入的百分比、自我报告的进食时间和一天中的时间来定义）的信息。使用障碍模型评估饮食酸摄入的类型和时间与中度至重度牙齿磨损的表面数量之间的关联，以解释过多的零计数和过度离散。模型调整了社会人口因素、胃酸反流药物和牙科保险覆盖范围。
软饮料的日摄入量与牙齿磨损有关，而水果、果汁和酒精饮料的摄入量则没有。与正餐一起饮用软饮料是唯一与牙齿磨损始终相关的因素，无论使用何种方法来定义正餐与零食。上述关联与有牙齿磨损的表面数量（在有该情况的人群中）有关，但与所有参与者中牙齿磨损的几率无关。
与正餐一起饮用软饮料与美国成年人的中度至重度牙齿磨损有关。其他酸性食物和饮料与牙齿磨损无关，无论其消费时间如何。
