Abstract

Purpose: A longitudinal dietary survey study measured dietary change and investigated factors influencing change from adolescence to adulthood.
Methods: Dietary data (2 x 3-day food diaries) were obtained from the same 187 respondents in 1980 (11.6 yrs) and 2000 (32.5 yrs). Foods consumed were assigned to one of the five categories from The Balance of Good Health [1]. Respondents were given feedback on their dietary change (1980 - 2000) and were asked to select, from a list of 24 explanatory factors, what might explain changes in their eating habits. Results: For five factors, change in eating patterns, were significantly different (p<0.05) between individuals who selected that explanatory factor and those who did not. ‘Desire to maintain health’ (n=122), ‘Change in food likes’ (n=113), ‘Body weight’ (n=103), and ‘Knowledge about food’ (n=101) were associated with a greater increase in fruit and vegetable intake, while ‘Type of job’ (n=74) was associated with a decrease. ‘Desire to maintain health’ and ‘Body weight’ were associated with a greater decrease in foods containing fat and/ or sugar. Only ‘Type of job’ was associated with an increase in meat, fish and alternatives. ‘Desire to maintain health’ and ‘Knowledge about food’ were associated with increased intake of bread, other cereals and potatoes.
Conclusions: Explanatory factors were associated with change in intake of food groups from adolescence to adulthood, which help to explain this complex and multi-factorial process.
