The determination of years of potential life lost (YPLL) can aid in monitoring changes in premature mortality among various population groups. While premature mortality has been shown to differ among blacks and whites, patterns of YPLL have not been well established among other racial groups. The Seneca Nation of Indians (SNI) is a Native American group residing primarily in western New York State (NYS). A review of SNI necrology records revealed that 55 percent (510 of 924) of the deaths between 1955 and 1984 occurred before 65 years of age. The proportion of premature deaths among males exceeded the proportion in females. SNI males demonstrated an increased risk of premature death (odds ratio = 1.43) relative to SNI females. Both the percentage of premature deaths and the number of YPLL per death were greater among SNI members compared with NYS residents. Almost one-half of all YPLL among the SNI were attributable to accidents and injuries. Heart disease, digestive diseases, and malignant neoplasms also represented important contributors to YPLL for both SNI males and females. This investigation identifies important causes of premature death among a Native American population and underscores the preventable nature of premature loss of life.
潜在寿命损失年数（YPLL）的确定有助于监测不同人群中过早死亡情况的变化。虽然已有研究表明黑人和白人的过早死亡率存在差异，但其他种族群体的YPLL模式尚未得到充分确立。塞内卡印第安人部落（SNI）是主要居住在纽约州西部（NYS）的一个美洲原住民群体。对SNI死亡记录的审查显示，1955年至1984年间，55%（924例中的510例）的死亡发生在65岁之前。男性过早死亡的比例超过女性。与SNI女性相比，SNI男性过早死亡的风险增加（优势比 = 1.43）。与NYS居民相比，SNI成员中过早死亡的百分比和每例死亡的YPLL数量都更高。SNI中几乎一半的YPLL可归因于意外事故和伤害。心脏病、消化系统疾病和恶性肿瘤也是SNI男性和女性YPLL的重要原因。这项调查确定了一个美洲原住民群体过早死亡的重要原因，并强调了过早死亡的可预防性。
