The aim was to determine the effect of migration from a non-industrialised to an industrialised society on age related changes in blood pressure and serum cholesterol.
The study was a comparison of major risk factors for cardiovascular disease in cross sectional surveys in two groups: Ethiopian immigrants and Israeli industrial employees.
Ethiopian immigrants were examined at Army induction centres in Israel; industrial employees were examined in the course of a national Israeli study on occupational risk factors for cardiovascular disease.
Participants were a sample of 387 male Ethiopians, aged 20-49 years, examined in 1987, who had immigrated to Israel three to four years previously, and a sample of 2747 male Israeli industrial employees in the same age group examined in 1985-7.
Among the Ethiopians there were no cases of overweight (Quetelet's index above 2.8) and only 6.7% were smokers, as compared with 20.7% overweight and 47.1% smokers among the other Israelis (p less than 0.001 for both variables). There were no significant differences in the prevalence of hypertension (11.6% and 13.0% for Ethiopians and other Israelis respectively). Hypercholesterolaemia (greater than 5.2 mmol/litre, 200 mg/dl) was much more prevalent among the other Israelis (42.0% v 9.6%, p less than 0.001). Blood pressures were similar and increased with age in both groups. However, in contrast to the other Israelis, average serum cholesterol among the Ethiopians was low and increased minimally with age. After regression adjustment for age and body mass index, blood pressures were higher among the Ethiopians, whereas serum cholesterol remained considerably higher among the other Israelis. Serum cholesterol was correlated with blood pressure in both groups.
Since Ethiopian immigrants have been found to have uniformly low blood pressures on arrival in Israel, these findings suggest that there is an age dependent effect on blood pressure resulting from migration which is not reflected in the serum cholesterol values.
本研究旨在确定从非工业化社会迁移至工业化社会对血压和血清胆固醇的年龄相关变化的影响。
本研究通过对两组人群进行横断面调查，比较心血管疾病的主要危险因素：埃塞俄比亚移民和以色列产业工人。
在以色列的征兵中心对埃塞俄比亚移民进行检查；在以色列一项关于心血管疾病职业危险因素的全国性研究中对产业工人进行检查。
研究对象为1987年接受检查的387名年龄在20 - 49岁之间的埃塞俄比亚男性样本，他们在三到四年前移民至以色列，以及1985 - 1987年接受检查的2747名同年龄组的以色列男性产业工人样本。
埃塞俄比亚人群中无超重病例（体重指数高于2.8），仅有6.7%的人吸烟，而其他以色列人群中20.7%超重，47.1%吸烟（两个变量的p值均小于0.001）。高血压患病率无显著差异（埃塞俄比亚人和其他以色列人分别为11.6%和13.0%）。高胆固醇血症（大于5.2 mmol/升，200 mg/dl）在其他以色列人群中更为普遍（42.0%对9.6%，p小于0.001）。两组的血压相似且均随年龄增长而升高。然而，与其他以色列人不同的是，埃塞俄比亚人的平均血清胆固醇水平较低，且随年龄增长增幅极小。在对年龄和体重指数进行回归调整后，埃塞俄比亚人的血压较高，而其他以色列人的血清胆固醇水平仍然显著较高。两组中血清胆固醇与血压均相关。
由于发现埃塞俄比亚移民在抵达以色列时血压普遍较低，这些研究结果表明，移民对血压存在年龄依赖性影响，而血清胆固醇值并未反映这一点。
