Hospital discharge rates for various immigrant groups resident in Greater London ahd the West Midlands were studied to compare the incidence of two diseases of the nervous system-motor neurone disease (MND) and multiple sclerosis (MS). For both these conditions immigrants from Europe, Ireland, America and from the old commonwealth countries of Canada, Australia, and New Zealand had discharge rates that were similar to those for people born in the United Kingdom. In contrast, immigrants from the new commonwealth countries of Asia, Africa, America (including the West Indies), and Europe (Gibraltar, Malta, and Gozo) had a greatly reduced risk of MS but a very similar risk of MND compared with those born in the United Kingdom. MS but not MND was rare among immigrants of Asian or African ethnic origin and uncommon among immigrants from the West Indies. Deaths attributed to MS and MND have also been studied. During a three-year period there were no deaths reported for MS among immigrants of Asian and African ethnic origin and 14 were expected. There were two deaths from MND among these immigrants and five were expected. Among the immigrants from the West Indies two deaths were attributed to MS and 13 were expected, and there were three deaths attributed to MND and four were expected. The contrast between MND and MS in hospital morbidity and mortality confirms that MS among immigrants to Britain is rare in those of Asian and African ethnic origin.

The suggested association between high consumption of beer and an increased risk of death from cancer of the colon and rectum was investigated among blue-collar workers at a Dublin brewery, who consume more than average amounts of beer, usually in the form of stout. A study of their mortality between 1954 and 1973 showed that they had as good an expectation of life as all Dublin males, with no increased risk of death from cancer of the oesophagus, pharynx, liver or of cirrhosis of the liver, accidents or suicide, conditions normally associated with the high consumption of alcohol. They had a significantly increased risk of death from cancer of the rectum and also from diabetes mellitus. Twenty per cent of the workers, differentiated by their place of work within the brewery, had a much higher risk of death from cancer of the rectum.

More than 48 500 South Africans annually are confronted with the diagnosis of cancer. (Sitas, 1994) Judging from the literature it would seem that the acquisition of information about the various aspects of their disease is a very important coping mechanism for the cancer patient. Various studies concerning the information needs of cancer patients have been published in the USA, the UK and Australia, Similar studies have not yet been published in South Africa.

A significant per centage of NCHDs (22%) continue to smoke, despite overwhelming evidence that this causes health problems. The prevalence in our study is lower than the national figure of 29%.
