Use of oral contraceptives in relation to dietary habits and alcohol consumption

The relationship between oral contraceptive (OC) use, dietary habits and alcohol consumption in young women was studied in Troms?, Norway. A total of 5,800 women aged 20-39 years answered a questionnaire in 1986/1987. Women with long-term duration of OC use reported more frequent intake of meat for dinner, preferred low-fat milk and drank less coffee. For other food items such as intake of fats, fish, fruit and vegetables, no differences were found. Strong associations were found for alcohol consumption, with increasing frequency of use among long-term users of OCs. These results are discussed in relation to the possible association between OC use and breast cancer in young women.
