After reviewing the death certificates of 2,820 South Carolina agricultural workers (including farmers, farm workers, and others in the agricultural industry) aged 35 to 84 during 1983-1984, we calculated proportional mortality ratios (PMRs). Among both white and nonwhite farmers in South Carolina, the PMR was significantly higher for cerebrovascular disease (whites, PMR = 1.20, P less than .05; nonwhites, PMR = 1.43, P less than .001) and lower for all malignant neoplasms (whites, PMR = 0.86, P less than .05; nonwhites, PMR = 0.78, P less than .001). In addition, external causes of death were elevated, attaining statistical significance for white farmers (PMR = 1.51, P less than .001). Significantly lower PMRs for all malignant neoplasms are attributed to fewer deaths from cancers related to smoking (buccal cavity and pharynx, esophagus, lung, and bladder) and colon and rectal cancers among both white and nonwhite farmers. White farmers did not show significantly elevated PMRs for cancers of the lymphatic and hematopoietic systems found in other studies in the Midwest. These data suggest that agricultural life-style can be improved for the prevention of strokes and for external causes of death.
在查阅了1983 - 1984年间南卡罗来纳州2820名年龄在35至84岁的农业工人（包括农民、农场工人及农业行业的其他人员）的死亡证明后，我们计算了比例死亡比（PMR）。在南卡罗来纳州的白人农民和非白人农民中，脑血管疾病的PMR显著更高（白人，PMR = 1.20，P <.05；非白人，PMR = 1.43，P <.001），而所有恶性肿瘤的PMR则较低（白人，PMR = 0.86，P <.05；非白人，PMR = 0.78，P <.001）。此外，外部死因有所升高，白人农民达到统计学显著水平（PMR = 1.51，P <.001）。所有恶性肿瘤的PMR显著较低归因于白人农民和非白人农民中与吸烟相关癌症（口腔和咽部、食管、肺和膀胱）以及结肠癌和直肠癌的死亡人数较少。在中西部其他研究中发现的淋巴和造血系统癌症，白人农民的PMR并未显著升高。这些数据表明，可以改善农业生活方式以预防中风和外部死因。
