Diminishing or increasing contrasts? Social class variation in Finnish food consumption patterns, 1979-1990.

The study examines whether social-class-based food consumption patterns changed in Finland during 1979-1990. The data were compiled by the National Public Health Institute in connection with a programme entitled 'Monitoring Health Behaviour among the Finnish Adult Population'. A questionnaire was sent annually to a random sample of Finns (N = 3400-5100, response rate 68-86%). This study was restricted to respondents 25-54 years old. Social class was defined by level of education (low, middle, high). Trends and variations in consumption patterns were studied by cross-tabulations and by fitting logistic regression models. The results show that the proportions of users of butter, high-fat milk and coffee sugar decreased during the study eriod whereas that of regular users of vegetables increased. Since the mid-1980s the shift towards 'healthier' food choices has accelerated among men, yet women are consistently more health-oriented. Social class appears to be a significant determinant of food consumption patterns. Men and women of lower social class follow trends set by upper social classes with a time lag of about ten years. Along with an overall shift towards observance of dietary recommendations, social class differences in Finnish food consumption patterns have diminished, without, however, disappearing altogether.
