A population-based case-control study of osteosarcoma cases is proposed among residents of New York State who were diagnosed between 1978 and 1987, at 24 years of age or younger. The primary focus of this research is to test whether there is a positive association between exposure to fluoride in a non-occupational setting and the onset of childhood osteosarcoma. In addition, this study will also investigate other potential risk factors such as growth and development, previous bone trauma, and prenatal exposure to chemicals and radiation. Cases will be identified from the New York State Cancer Registry. An equal number of controls will be chosen from live birth records. The controls will be frequency matched to the cases regarding sex, year of and age at diagnosis using an innovative method. Each person will be traced from the date of diagnosis to the present using Motor Vehicle records, telephone directories and other methods. The primary source of exposure data will be telephone interviews with the subjects and/or their parents. Medical, dental and school health records also will be abstracted for a random 50% sub-sample. The data obtained from these records will be used to validate the interview information. Logistic regression analysis and other statistical techniques will be used to assess the effect of risk factors controlling for confounding variables such as sociodemographic status. Due to the common practice of fluoridating drinking water and the protective effect of fluoride against dental caries, it is important to determine whether fluoride intake could be an etiologic factor for osteosarcoma. This study also satisfies the requirements of the program announcement for small grants by investigating an emergent issue in cancer epidemiology, by planning a complex epidemiologic investigation, and by developing a new methodologic procedure for frequency matching.

提议对骨肉瘤病例进行基于人群的病例对照研究 1978 年至 1978 年期间被诊断出的纽约州居民 1987年，24岁以下。 本研究的主要焦点 是为了测试暴露与暴露之间是否存在正相关关系 非职业环境中的氟化物和童年时期的氟化物 骨肉瘤。 此外，本研究还将调查其他 潜在的风险因素，例如生长和发育、以前的骨骼 外伤以及产前接触化学品和辐射。 病例将从纽约州癌症登记处确定。 一个 将从活产记录中选择相同数量的对照。 这 控制措施将与有关性别、年份的案例进行频率匹配 使用创新方法进行诊断时的年龄。 每个人都会 使用机动车辆追溯自诊断日期至今 记录、电话簿和其他方法。 主要来源 暴露数据将是对受试者的电话采访和/或 他们的父母。 医疗、牙科和学校健康记录也将被保存 抽取随机 50% 的子样本。 从这些得到的数据 记录将用于验证访谈信息。 物流 将使用回归分析和其他统计技术 评估控制混杂变量的风险因素的影响 例如社会人口状况。 由于饮用水氟化的普遍做法以及 氟化物对龋齿有保护作用，重要的是 确定氟化物摄入量是否可能是该病的病因 骨肉瘤。 本研究也满足该计划的要求 通过调查紧急问题宣布小额赠款 癌症流行病学，通过计划一项复杂的流行病学调查， 并开发一种新的频率匹配方法程序。
