The Impact of Nutrition Education on Dietary Behavior and Iron Status in Participants of the Supplemental Food Program for Women, Infants and Children, and the Expanded Food and Nutrition Education ProgramChristensen, Nedra K. 01 May 1993 (has links)
This study was conducted to determine the impact of nutrition edu cation on participants of the Supplemental Food Program for Women, Infants and Children (WIC) and the Expanded Food and Nutrition Education Program (EFNEP). The specific objectives were to: 1) determine the impact of participation in EFNEP on iron status as assessed by hematocrit (hct) and ferritin levels; 2) determine the effect of nutrition knowledge on hct and ferritin values; and 3) determine the effect dietary behavior has on hct and ferritin levels for both WIC and EFNEP participants.
Each study participant completed a 24-hour dietary recall record plus food frequency record, medical history, validated nutrition knowledge test, and finger stick blood sample prior to program enrollment or nutrition education, and again six months later. There were 42 WIC, 26 EFNEP, 23 WIC-control, and 23 EFNEP-control participants.
Paired t-tests were used to find differences between preprogram and postprogram evaluation scores for the variables of nutrition knowledge score, hematocrit level, ferritin level, and levels of several nutrients. Nutrition knowledge test scores increased significantly from preprogram to postprogram for both WIC and EFNEP participants (14.2 ± 3.27 to 15.5 ± 2.89 for WIC, 14.2 ± 3.77 to 15.6 ± 2.79 for EFNEP). EFNEP participants also increased significantly in hct levels (38.5% ± 3.78 to 40.7% ± 2.13). Hematocrit levels did not change significantly for the WIC or control groups and nutrition knowledge did not increase for the control group between preprogram and postprogram evaluations.
Mean intakes of vitamin A, vitamin c, calcium, and protein were above the RDA at preprogram and postprogram evaluations, yet the percentage of individual participants who consumed less than 67% of the RDA in this study was higher than in the continuing survey of Food Intake of Individuals - 1985. Improvement in nutrient intake at postprogram evaluations was encouraging.
Regression analysis indicated that nutrition education classes in college, income level, and level of formal education each had a positive effect on nutrient intake and nutrition knowledge.

Exploring a combined quantitative and qualitative research approach in developing a culturally competent dietary behavior assessment instrumentJones, Willie Brad 22 June 2009 (has links)
Cultural competence is widely recognized as an essential strategy for reducing health disparities. As the United States' population becomes increasingly ethno-culturally diverse, these disparities are becoming even more pronounced. One particular challenge in this regard concerns overweight/obesity prevalence among American adults, as a disproportionately high number of racial and ethnic minority adults are classified as overweight or obese. Dietary behavior assessments are often utilized by health and human services professionals to obtain the data necessary to promote goals such as the reduction and elimination of overweight/obesity across all ethno-cultural groups.
The primary objective of this research study was to develop, test, and evaluate a culturally-competent dietary behavior assessment instrument by effectively synthesizing qualitative methods from Cognitive Anthropology with appropriate survey research and quantitative statistical methods. Specifically, a quantitative methods triangle of hierarchical cluster analysis, binary logistic regression, and Poisson regression in conjunction with the free listing qualitative research technique from Cognitive Anthropology was explored as a possible combined methodological approach for researchers and public health professionals wishing to develop a comprehensive understanding of dietary behaviors at the local community level.
Binary logistic regression and Poisson regression enabled the relationship between selected food categories and certain demographic/cultural indicators to be modeled, while hierarchical cluster analyses enabled modeling of the distinct patterns of food category groupings that comprise individuals' regular diet. Additionally, initial qualitative analyses of the raw data promoted an understanding of the influence that the local fast food and dine-in restaurant environment has on the dietary behaviors of the target population.
The results of this study suggest that a quantitative methods triangle of hierarchical cluster analysis, binary logistic regression analysis, and Poisson regression analysis founded upon qualitative research principles has potential for use as a combined methodological approach for researchers and public health professionals wishing to develop a comprehensive understanding of dietary behaviors at the local community level. By employing these techniques, researchers can analyze individual dietary behaviors and eating patterns from a multifaceted perspective. In turn, public health professionals can develop community-based, cross-culturally relevant programs and interventions that are equally effective across all ethno-cultural groups in their target population.

Gesundheitszuschreibung zu Superfood – Eine Umfrage in der gesunden BevölkerungWindisch, Michaela 24 April 2023 (has links)
Superfoods – exotische und einheimische mit überdurchschnittlich hoher Nährstoffdichte, folglich gesundheitsförderndem Wirkversprechen, erfreuen sich stetiger Beliebtheit. Insbesondere deren sekundäre Pflanzenstoffe, antioxidative Eigenschaften und Vitamine zielen gesundheitsfördernd auf den menschlichen Organismus ab. Superfoods leben vom diskursiven Austausch. Demzufolge lassen sich Menschen durch Meinungen und Erfahrungsberichte beeinflussen. Vor diesem Hintergrund wird vorhandenes Bewusstsein in der gesunden Bevölkerung um den gesundheitsfördernden Nutzen untersucht. Quantitativ, mittels standardisierter online-Befragung, wird zum Konsum, ernährungsphysiologischen Hintergründen sowie Beweggründen zu Gesundheitszuschreibung und Ernährung, befragt. Das resultieren-de Meinungsbild zeigt Bewusstsein zum gesundheitsfördernden Nutzten von Superfood. Auseinandersetzungen zu Verzehrmengen und Risikobewertungen sind jedoch gering vorhanden. Das Potenzial optimaler Anwendung wird nicht ausgeschöpft, um Superfoods gesundheits- und nährstoffbezogen aktiv in das Ernährungsverhalten einzubinden. „Wohlbefinden“ und „Geschmack“ stehen im Fokus. Die Forschungsergebnisse leisten einen grundlegenden Beitrag zur Gesundheitszuschreibung. Das Meinungsbild wird theoriebasierend vergleichend diskutiert, weiterführende Forschungsbedarfe abgeleitet, um künftig umfangreiches Bewusstsein zu generieren sowie Auswirkungen auf Gesundheit und zielgerichteten Konsum näher zu hinterfragen.:Abkürzungsverzeichnis V
