Food shopping practices are associated with dietary quality in low-income households.
ABSTRACT ABSTRACT Nutrition education for low-income audiences often focuses on building skills in food shopping and food resource management to help families receive the best nutrition from the resources they have available. However, empirical evidence for the effect of food shopping practice on dietary quality has been limited. This article presents new analyses from two studies that found an association between food shopping practices and diet quality. Logistic regression of data from 957 respondents from the 1996 National Food Stamp Program Survey found that food shopping practices were significantly (p </= .05) associated with the availability of nutrients in the food the households used during a week. Similarly, analysis of baseline data from 5159 women from selected counties of states who participated in the Expanded Food and Nutrition Education Program found that food shopping practices were significantly (p </= .05) associated with increased consumption of nutrients as measured through a single 24-hour recall. These findings suggest that food shopping practices are an important area for nutrition education with low-income audiences.

ABSTRACT: This article aims to help health professionals who do not have a knowledge of survey design to evaluate and design nutrition knowledge measures. Historically, these measures have been poorly designed and therefore may not assess nutrition knowledge accurately, with the consequence that the results may have little meaning. This paper highlights the factors to look for in existing measures or, if a suitable measure cannot be found, shows how to modify or design one that will give useful and interpretable results. General design concepts are covered including the generation of items, the use of a pilot study and item analyses, and assessment of validity and reliability, as well as particular issues posed in the nutrition field, such as the interpretability of food terms. Researchers are advised to use an existing measure, or modify an existing measure if possible, before developing a new one. Whether evaluating or developing a measure, the importance of the content, structure, and statistical evaluation is discussed. Collaboration between nutritional and behavioral scientists is recommended to provide complementary areas of expertise in the evaluation/development of nutrition knowledge measures.Journal of Nutrition Education. 01/2000;

ABSTRACT: To describe the relationship of new measures of hunger and food insecurity to household food supplies and individual food and nutrient intake. A questionnaire containing the Radimer/Cornell hunger and food insecurity items and questions on eating patterns and the frequency of fruit and vegetable consumption was administered to subjects during a personal interview in their homes. A 24-hour diet recall and a household food inventory were conducted at the initial interview and at a follow-up visit. Participants were 193 women drawn from a random sample of 308 women who had completed a previous health census in a rural New York State county. Subjects' ages ranged from 15 to 40 years. All had children living at home and less than 16 years of education. Regression analysis was used to test for linear trends across food insecurity groups for the household food inventory scores and for the frequency of consumption of fruits and vegetables. t Tests were used to assess differences between the food secure and food insecure groups for nutrient and food group means. A chi 2 test for trend was used to examine differences in the distribution of nutrient and fruit and vegetable intake between the food secure and food insecure groups. A significant decrease in the frequency of consumption of fruits and vegetables and the amount of food in the household and a significant increase in scores indicative of disordered eating patterns were associated with a worsening of food insecurity status. Potassium and fiber intake and fruit consumption differed significantly between the food secure and food insecure groups. The percentage of respondents consuming less than the Recommended Dietary Allowance for vitamin C and fewer than five fruits and vegetables per day was significantly greater among food insecure respondents than food secure respondents. The quantity of food available in households and consumption of fruits and vegetables decreased with increasingly severe problems with food insecurity and hunger. In this rural population, the Radimer/ Cornell measures were useful in identifying households experiencing food insecurity and providing information about the nature of the food supply and the dietary intake problems experienced by food insecure households and persons, suggesting that these measures may be useful on community surveys designed to examine food insecurity issues.Journal of the American Dietetic Association 11/1996; 96(10):1019-24; quiz 1025-6. · 3.80 Impact Factor
