Variations in Ischaemic Heart Disease mortality in men in Hong Kong were analysed using registered deaths from 1976 to 1981 and the 1981 Census population, and earlier years. Age-specific rates in Hong Kong as a whole are lower than in Britain and in the USA and have changed relatively little over the past ten years. Standardised Mortality Ratios (SMRs) for districts, Proportional Mortality Ratios (PMRs) for occupations, and Direct Age-Standardized Mortality rates were calculated, using the whole of Hong Kong in 1981 as the standard. In 1981 the SMRs for the affluent districts were significantly high while the SMRs of the most rural areas were significantly low. Although the affluent districts had high proportions of non-Chinese deaths, these were not sufficient to explain the high SMRs. In affluent districts there were high proportions of professional, administrative and managerial workers who had significantly high PMRs for Ischaemic Heart Disease. The district SMRs were positively correlated with the proportions of these workers. The conclusion is that in Hong Kong in 1981, higher levels of socio-economic status were associated with higher levels of Ischaemic Heart Disease in men. Further studies are being made, and attention will be paid in risk-factor studies to areas and population groups with higher risks.
利用1976年至1981年的登记死亡数据以及1981年的人口普查数据和更早年份的数据，对香港男性缺血性心脏病死亡率的变化进行了分析。香港整体的年龄别死亡率低于英国和美国，并且在过去十年中变化相对较小。以1981年的全香港人口为标准，计算了各地区的标准化死亡率（SMR）、职业的比例死亡率（PMR）以及直接年龄标准化死亡率。1981年，富裕地区的SMR显著较高，而最偏远农村地区的SMR则显著较低。尽管富裕地区非华裔死亡比例较高，但这些不足以解释高SMR。在富裕地区，专业、行政和管理人员比例较高，他们患缺血性心脏病的PMR显著较高。地区SMR与这些工人的比例呈正相关。结论是，1981年在香港，较高的社会经济地位与男性较高的缺血性心脏病发病率相关。正在进行进一步研究，并且在危险因素研究中将关注高风险地区和人群。
