Nutrition knowledge as influenced by source of nutrition information
1991
Medeiros, L. | Russell, W. | Shipp, R.
A telephone survey (n=1560) was conducted to assess sources of nutrition information and the ability to correctly identify false statements regarding nutrition. The use of media and, to a lesser degree, physicians for nutrition information were reported with the greatest frequency. Gender, marital status, age, and income significantly influenced choice of information source (p<.05). Use of extension home economists, newspapers, nutritionists/dietitians, books and/or magazines, or newspapers had a positive influence on nutrition knowledge. Nutrition knowledge was negatively impacted by use of physicians/nurses and television/radio as sources of information (p<.05). Log linear regression analysis revealed that several information sources had greater weight than others in predicting correct nutrition knowledge (p<.05). Given the wide range in knowledge of respondents citing various information sources, it is evident that the nutrition information sources studied are not equally effective in delivering their messages.
