Compliance with the Australian Dietary Guidelines in the early 1990's: have population-based health promotion programs been effective?

Abstract

In an attempt to change the dietary behaviours of the population (and reduce the incidence of diet-related disease), governments and health authorities in Australia have developed Dietary Guidelines. These guidelines have been communicated to the wider society through a range of channels, such as health promotion programs and education campaigns. Studies conducted during the 1980's suggested that up to 30 percent of the population were engaging in food-related behaviours consistent with dietary guideline recommendations, although the extent of compliance varied by population sub-group (eg women and high socioeconomic groups were more likely to comply). More recent research has suggested that compliance with some of the guideline recommendations has increased, although disparities between population sub-groups remain. The aim of this present study is to determine the extent of compliance with the Australian Dietary Guidelines in the early 1990's, and thereby (indirectly) assess the degree to which health promotion efforts have affected the dietary behaviours of the population. The study is based on a representative sample (n = 403, 80.6% response rate) of Brisbane city. Overall, it was estimated that between 40 and 60 percent of the population were regularly engaging in food behaviours consistent with guideline recommendations. This rate of compliance, however, differed markedly depending on the type of behaviour being examined, and it varied significantly (albeit modestly) across different population sub-groups. It is concluded that health promotion has influenced the population's dietary behaviours, although traditional beliefs and attitudes also inform our food behaviours to a considerable extent.
