078 Incidence rates and survival trends of cancer in 0-29-year-olds by ethnic group in Yorkshire, UK

Abstract

aspects of Russian drinking behaviour and its consequences are related to scores obtained from the internationally recognised AUDIT instrument for detecting alcohol problems. Design Population-based age-stratified cross sectional survey. Setting Izhevsk, Russia. Participants 925 men aged 25e59 years. Main outcome measure Men and proxy respondents completed an interview including questions on alcohol consumption and socioeconomic and demographic variables. These included questions on six drinking behaviours and their consequences. These were: going on zapoi (a period of continuous drunkenness of two or more days); drinking non-beverage alcohol; frequency of excessive drunkenness; frequency of hangover; drinking before noon and frequency of sleeping in clothes at night because of drunkenness. The men also completed a Self Completed Questionnaire containing questions constituting the alcohol use disorders identification test (AUDIT). Results There was a strong association with AUDIT score and hazardous drinking (one or more episodes of zapoi in the past year or drinking non beverage alcohol or twice a week or more occurrence of excessive drunkenness, hangover or going to sleep at night clothed because of drunkenness) using both proxy and self report of drinking behaviours (self-report OR 5.25 95% CI 2.86 to to 9.65). The association was stronger when proxy report was used (proxy-report OR 6.66 95% CI 4.00 to to 11.07). The same pattern was seen for all the drinking behaviours individually. Confirmatory factor analysis supported a two factor structure for the AUDIT measuring alcohol consumption and alcohol related problems. Hazardous drinking behaviour specific to Russia was more strongly associated with AUDIT questions relating to alcohol related problems than to questions measuring consumption. Conclusions The drinking behaviours used in this paper are unconventional measures of hazardous drinking. The strong association with AUDIT shows that both self and in particular proxy report of distinctive directly observable drinking behaviours provide useful data on alcohol consumption and abuse in Russian men. Objective Few studies have examined differences in the epidemiology of cancer between ethnic groups for children and young adults in the UK. We investigated incidence rates, associated trends and survival by ethnicity (south Asian vs all other ethnic groups) across childhood (0e14) and young adult (15e29) ages using a unique specialist cancer register. Methods The data used for this study were extracted from the Yorkshire Specialist Register of Cancer in Children and Young People. Patients diagnosed from 1990 to 2005 in the former Yorkshire Regional Health Authority were included in the analysis. Ethnicity was assigned using name analysis programs and Hospital Episode Statistics data. Incidence rates (per 1 000 000 person-years) by ethnic group were derived using mid-year population estimates. Poisson regression was used to examine trends in incidence by ethnicity and diagnostic sub-group, adjusting for sex and ag...
