Background Links between diet in childhood and the prevention of disease in adulthood have been established. This longitudinal dietary survey provided quantitative evidence of dietary change from adolescence to adulthood, in Northumberland, England.

Objective To report longitudinal dietary change in 198 respondents between the ages of 12 and 33 years, to explore dietary ‘tracking’ between the same time points and to describe the effects of gender, socio-economic status and location on dietary change.

Methods A longitudinal study recorded dietary change from adolescence to adulthood. Two 3-day food diaries were collected in 1980 and 2000 from the same 198 respondents. Foods consumed were assigned to the five categories in the Balance of Good Health (BGH). Demographic and socio-economic information were obtained in 1980 and 2000.
