This study examined trends in the price of healthy and less-healthy foods from 1989 to 2007 using the Australian Consumer Price Index (CPI).
CPI food expenditure classes were classified as 'core' or 'non-core'. Trends in the CPI were analysed to examine the rise in prices of core compared with non-core foods.
On average, the CPI for core foods has risen at a slightly higher, though not statistically significant, rate than non-core foods. Furthermore, selected groupings reveal interesting patterns. 'Bread' has risen in price significantly more than 'cakes and biscuits', and 'milk' has risen in price significantly more than 'soft drinks, waters and juices'.
This investigation of food price trends reveals notable differences between core and non-core foods. This should be investigated further to determine the extent to which this contributes to the higher prevalence of diet-related diseases in low socio-economic groups.
本研究利用澳大利亚消费者物价指数（CPI）调查了1989年至2007年健康食品和不太健康食品的价格趋势。
将CPI食品支出类别分为“核心”或“非核心”。分析CPI趋势，以研究核心食品与非核心食品价格的上涨情况。
平均而言，核心食品的CPI上涨速度略高于非核心食品，尽管在统计学上无显著差异。此外，特定类别呈现出有趣的模式。“面包”价格上涨幅度明显高于“蛋糕和饼干”，“牛奶”价格上涨幅度明显高于“软饮料、水和果汁”。
对食品价格趋势的这项调查揭示了核心食品与非核心食品之间的显著差异。应进一步对此进行调查，以确定其在多大程度上导致了社会经济地位较低群体中与饮食相关疾病的较高患病率。
