SynopsisRates and methods of suicide during 1961–70 of migrants in Australia were compared with native born Australians. Large differences in both rates and methods of suicide were found in individual migrant groups. The rates were more akin to those in the country of origin than of the Australian-born, no matter how long the migrants had lived in Australia. By contrast, methods of suicide used by migrants approached more closely those of the Australian-born the longer they had lived in Australia. The change in methods used was greatest in those migrant groups coming from countries with a language and culture more akin to those in Australia. A discussion follows of various possible sociological and cultural factors, both within the countries of origin and within Australia, which could have contributed to these results.

In 2119 unselected Busselton subjects 40 to 79 years of age, the 13 year mortality from cardiovascular disease was significantly higher in those whose initial electrocardiogram showed Q and QS patterns, left axis deviation, ST depression, T wave depression, flat or biphasic T waves, atrial fibrillation or flutter, and ventricular extrasystoles. In angina-free subjects whose electrocardiographic codes occurred in isolation from any other electrocardiographic abnormality, ventricular extrasystoles were associated with significantly higher mortality from cardiovascular disease compared with controls.
