Western agriculture, in comparison with Midwestern and Eastern, is more diverse, with a drier climate, mild winters, and different exposures. This randomly selected cohort of 1947 Californian farmers confirmed the usual finding: a lower mortality rate than general population (by 50%). A low smoking prevalence and healthy worker effect are likely contributors. Although farmers were more likely to die from injuries and skin cancer, death was less likely from Alzheimer's and cerebrovascular diseases. Within the cohort, disability and persistent wheeze were associated with increased mortality. The 200 deaths were insufficient to determine the significance of rare diseases.
与中西部和东部相比，西部农业更加多样化，气候干燥，冬季温和，光照条件也不同。对随机抽取的 1947 年加利福尼亚州农民的这一队列研究证实了通常的发现：其死亡率比一般人群低（低 50%）。低吸烟率和健康工人效应可能是促成因素。尽管农民死于伤害和皮肤癌的可能性更高，但死于阿尔茨海默病和脑血管疾病的可能性更小。在队列中，残疾和持续性喘息与死亡率增加有关。200 例死亡不足以确定罕见疾病的意义。
