On Friday 25 April at 14:00, Christian S. Antoniussen defends his PhD dissertation entitled "Longitudinal measures of alcohol consumption throughout adulthood and the risk of invasive breast cancer among postmenopausal women".

Several studies have associated alcohol consumption with the risk of breast cancer among postmenopausal women. However, despite substantial evidence of the effect of alcohol consumption on the risk of breast cancer, it remains largely unknown whether changes in alcohol consumption habits during adulthood and different alcohol consumption patterns are associated with breast cancer risk.

Using data from two large cohorts, we estimated midlife changes in alcohol intake and identified several distinct alcohol consumption patterns throughout adulthood using latent class mixed models. We used regression models to estimate the risk of breast cancer associated with both midlife changes in alcohol intake and the identified alcohol consumption patterns.

Overall, the results of this PhD project suggest that alcohol consumption patterns characterised by moderate to high intake throughout adulthood are associated with a higher risk of breast cancer compared to consistently low intake. These results indicate the need for a focus on preventative measures targeting hazardous alcohol consumption behaviour, implemented early in life, in order to mitigate breast cancer risk associated with the consumption of alcoholic beverages.

The summary is written by the PhD student.

The defence is public and takes place at Department of Public Health, Sport Science, Aarhus University, auditorium 137, building 3410. Please see the press release for more information.
