Organic food consumption is associated with a healthy lifestyle, socio-demographics and dietary habits: a cross-sectional study based on the Danish Diet, Cancer and Health cohort.

OBJECTIVE

To study the association between organic food consumption and lifestyle, socio-demographics and dietary habits.

DESIGN

Cohort participants completed detailed questionnaires about organic food consumption, diet and lifestyle between 1999 and 2002. Polytomous logistic regression models were used to estimate the association between organic food consumption, and lifestyle, socio-demographics, and dietary habits.

SETTING

This cross-sectional study uses data from the Danish Diet, Cancer and Health cohort.

PARTICIPANTS

A total of 43 209 men and women aged between 54 and 73 years were included in the study.

RESULTS

Overall, 15 % reported never consuming organic food, 39 % had low organic food consumption, 37 % had medium organic food consumption and 10 % had high organic food consumption. The relative risk of consuming organic food versus never consuming organic food was highest among women, persons with BMI < 25 kg/m2, persons with low alcohol intake, persons participating in sports, persons who did not smoke or were former smokers, and among persons who adhered to the Danish national dietary guidelines. Associations were more distinct with higher levels of organic food consumption.

CONCLUSION

Based on a historical cohort of Danish adults, organic food consumption was associated with a generally healthy lifestyle, more favourable socio-demographics and dietary habits. These findings have to be considered in the adjustment strategy for future studies linking organic food consumption with health outcomes.
