The study was initiated by public concern about exposure to an industrial park (IP) emission. The study examined whether mortality in the Bedouin population in the southern part of Israel is associated with the residential distance to the IP.
Ecological study during 1995-2001 included the entire Bedouin population. Mortality data was obtained from the Central Bureau of Statistics. As an indirect measurement of exposure we used residential distance to the IP (with 20 km radius as a cut-of-point) based on residents' complaints about odor related to the IP. Differences in mortality rates by distance were assessed by the Mantel-Haenszel relative risk (M-H RR) within the 95% CI. The country Arab population served as a reference for calculation of the age-adjusted standardized mortality ratio (SMR).
Increased mortality rates due to symptoms/ill-defined conditions and non-external causes were observed in the Bedouin population of both sexes, residing up to 20 km from the IP, compared to those living in more remote areas. Corresponding M-H RR (plus 95% CI) were 1.66 (1.17-2.36), 1.24 (1.06-1.44) in females, and 1.55 (1.15-2.10), 1.32 (1.15-1.52) in males.
The study results suggest an association between residential proximity to the regional IP and increased mortality rates in the Negev Bedouin population. These findings have been accepted by the authorities as an issue for community health protection.
该研究是由公众对工业园区排放物暴露的担忧引发的。该研究调查了以色列南部贝都因人群的死亡率是否与距工业园区的居住距离有关。
1995 - 2001年的生态学研究涵盖了整个贝都因人群。死亡率数据来自中央统计局。作为暴露的间接测量指标，我们根据居民对与工业园区相关气味的投诉，使用距工业园区的居住距离（以20公里半径为分界点）。通过Mantel - Haenszel相对风险（M - H RR）在95%置信区间内评估不同距离的死亡率差异。该国阿拉伯人群作为计算年龄调整标准化死亡率（SMR）的参照。
与居住在更偏远地区的人相比，居住在距工业园区20公里范围内的贝都因男女群体中，因症状/不明疾病和非外部原因导致的死亡率有所上升。相应的女性M - H RR（及95%置信区间）为1.66（1.17 - 2.36）、1.24（1.06 - 1.44），男性为1.55（1.15 - 2.10）、1.32（1.15 - 1.52）。
研究结果表明，居住在区域工业园区附近与内盖夫贝都因人群死亡率上升之间存在关联。这些发现已被当局认可为社区健康保护问题。
