Cancer mortality is high among white men residing in southern Louisiana parishes (counties). In an effort to elucidate this phenomenon, we studied three environmental correlates of cancer-namely, smoking, residence in urban communities, and residence in the wetlands. Multiple regression analysis was applied to cancer mortalities adjusted for age and urban residency, and specific for race, sex, amount of standing water area in the parish, and cancer site. Cancer sites were grouped according to their correlation with smoking: strong, moderate, and no correlation. For men, the smoking-related cancer mortality not only showed an association with residence in wetlands but also was higher in the Louisiana wetlands than in the remainder of the United States.
居住在路易斯安那州南部教区（县）的白人男性癌症死亡率很高。为了阐明这一现象，我们研究了癌症的三个环境相关因素，即吸烟、居住在城市社区以及居住在湿地地区。多元回归分析应用于根据年龄和城市居住情况调整后的癌症死亡率，并针对种族、性别、教区积水面积和癌症部位进行了具体分析。癌症部位根据其与吸烟的相关性进行分组：强相关、中度相关和无相关性。对于男性而言，与吸烟相关的癌症死亡率不仅与居住在湿地地区有关，而且在路易斯安那州湿地地区的死亡率高于美国其他地区。
