Gender differences in adults' knowledge about fat and cholesterol.
Cognitive learning theories suggest that an individual's prior knowledge is a major factor for determining what can be learned. The objectives of this study were to compare the organization of knowledge about fat and cholesterol in adult, middle-class men and women and changes in that knowledge after reading an educational bulletin. Forty men and 48 women participated in two semistructured interviews to assess their knowledge; half received a US Department of Agriculture bulletin on fat and cholesterol at the end of the first interview. Concept maps (two-dimensional representations of an individual's cognitive knowledge structure) were made from the interview transcripts to assess knowledge organization. Both genders had limited knowledge, scoring less than 25% of the maximum possible score at interview 1. Overall, known and not known concepts were similar in men and women; however, women had slightly more integrated knowledge and more misconceptions than men. Both groups receiving the bulletin made significant gains in knowledge at interview 2, but knowledge gains were twice as great in men as in women. Our findings indicate that practitioners need not create separate materials about fat and cholesterol for middle-class men and women.
