The aim of this study was to investigate changes in the average blood pressure of Australian-born and Italian-born men and women after a 20-year interval, in the same location, the Melbourne suburb of Brunswick, located about five km north of the centre of the city. Data pertaining to blood pressure and its control were obtained from all Australian- and Italian-born residents of Brunswick enrolled in the Melbourne Collaborative Cohort Study between 1990 and 1994. Comparisons were made with published data from a random household survey in Brunswick in 1972. Within the age group 40 to 59 years (in contrast to the earlier study) average blood pressure was significantly higher in Italian-born men and women relative to the Australian-born. Between 1972 and 1990-1994, significant reductions in average systolic and diastolic blood pressure occurred in Australian-born women aged 40 to 59 years. Average systolic and diastolic blood pressures also fell in Australian-born men, although the reduction in systolic blood pressure for those aged 50 to 59 was not statistically significant. Average systolic blood pressure increased in Italian-born men and women. However, the increase was statistically significant only for men aged 50 to 59 years. Average diastolic blood pressure increased in Italian-born men aged 50 to 59 and fell in Italian-born women of the same age. The observed changes in blood pressure could not be attributed directly to changes in the diagnosis and treatment of hypertension, or to changes in the prevalence of overweight and obesity.
本研究的目的是调查在20年的时间间隔后，出生在澳大利亚和意大利的男性和女性的平均血压变化情况，研究地点在墨尔本市中心以北约5公里处的布伦瑞克墨尔本郊区。与血压及其控制相关的数据来自1990年至1994年参与墨尔本协作队列研究的布伦瑞克所有出生于澳大利亚和意大利的居民。研究将这些数据与1972年布伦瑞克一项随机家庭调查的已发表数据进行了比较。在40至59岁年龄组（与早期研究不同）中，出生于意大利的男性和女性的平均血压相对于出生于澳大利亚的男性和女性显著更高。在1972年至1990 - 1994年间，40至59岁出生于澳大利亚的女性的平均收缩压和舒张压显著降低。出生于澳大利亚的男性的平均收缩压和舒张压也有所下降，不过50至59岁男性的收缩压下降在统计学上并不显著。出生于意大利的男性和女性的平均收缩压有所上升。然而，只有50至59岁的男性上升具有统计学意义。50至59岁出生于意大利的男性的平均舒张压上升，而同龄出生于意大利的女性的平均舒张压下降。观察到的血压变化不能直接归因于高血压诊断和治疗的变化，也不能归因于超重和肥胖患病率的变化。
