title: Diet, obesity and education in three age groups of Saskatchewan women.
abstract: Research on relationships between socioeconomic status and Canadians' diet is limited. The current study investigated differences by education in dietary variables shown to be related to obesity; it included three age groups of Saskatchewan women who participated in the 1992 to 1993 Heart Health Intervention Evaluation baseline study. Multistage sampling was used to select randomly from the Saskatchewan Health Insurance Registration File. The overall response rate was 42.6%; a sample representative of the general Saskatchewan population was obtained. Three-day estimated food records and demographic information from 396 women aged 18 to 74 years were subdivided into three age categories: 18 to 34 years, 35 to 54 years, and 55 to 74 years. For the 18- to 34-year group, obesity was significantly more prevalent with lower education; trends were similar for the older age groups. Under-reporting of energy intake (indicated by an energy intake:basal metabolic rate ratio of <1.1) was related to obesity but not to education. The greatest differences in diet between educational groups were observed in the 18- to 34-year group; fewer differences existed in the 35- to 54-year group, and none in the 55- to 74-year group. Health promotion efforts need to be targeted appropriately, and based on differences in dietary intakes by socioeconomic group. Research should help promote an understanding of the reasons for differences in diet by socioeconomic status.
