Abstract

The purpose of the study was to assess the determinants of nutrition behaviors and body mass index and determine the impact of a nutrition education intervention (NEI) among Mauritian housewives. A pretest-posttest design was used assessing Nutrition Knowledge (NK), Nutrition Attitudes, Fruit and Vegetable Intake (FVI), body mass index (BMI). Two hundred Mauritian housewives were recruited. The NEI was in the form of a lecture and lasted for twenty minutes. Statistical tests performed revealed that the mean NK score at baseline was 65.8 ± 6.92 and a significant increase of +17.1 at post-test and +16.1 at follow-up was observed. Determinants of NK were age, presence of elderly people, and BMI. Mean nutrition attitude score at baseline was 2.37 ± 0.22 with significant increase of +0.2 (post-test) and +0.17 at follow-up. Age, level of education, presence of elders, and NK were linked to a positive attitude. FVI was predicted by age, income, presence of elders, NK, and nutrition attitudes. Baseline FVI was 4.77 ± 1.11 which increased significantly ( p < 0.001) to 4.98 ± 1.13 at post-test and 5.03 ± 1.20 at follow up. NEI had a positive impact suggesting the benefits of such intervention in the promotion of healthy nutrition behaviors.

Development of a general nutrition knowledge questionnaire for adults.

K. Parmenter, J Wardle (1999)

This paper describes the development of a reliable and valid questionnaire to provide a comprehensive measure of the nutritional knowledge of UK adults. The instrument will help to identify areas of weakness in people's understanding of healthy eating and will also provide useful data for examining the relationship between nutrition knowledge and dietary behaviour which, up until now, has been far from clear. Items were generated paying particular attention to content validity. The initial version of the questionnaire was piloted and assessed on psychometric criteria. Items which did not reach acceptable validity were excluded, and the final 50 item version was administered to two groups differing in nutritional expertise on two occasions to assess the construct validity and test-retest reliability. The questionnaire was developed in 1994 in the UK. Three hundred and ninety-one members of the general public, recruited via their places of work, completed the questionnaire at the piloting stage. The final version was administered to 168 dietetics and computer science students following a university lecture. The internal consistency of each section was high (Cronbach's alpha = 0.70-0.97) and the test-retest reliability was also well above the minimum requirement of 0.7. Nutrition experts scored significantly better than computer experts [F(1167) = 200.5, P<0.001], suggesting good construct validity. The findings demonstrate that the instrument meets psychometric criteria for reliability and construct validity. It should provide a useful scale with which to reassess the relationship between knowledge and dietary behaviour.

Fruit and vegetable intake among urban community gardeners.

Katherine Alaimo, Elizabeth Packnett, Richard A Miles … (2008)

To determine the association between household participation in a community garden and fruit and vegetable consumption among urban adults. Data were analyzed from a cross-sectional random phone survey conducted in 2003. A quota sampling strategy was used to ensure that all census tracts within the city were represented. Flint, Michigan. 766 adults. Fruit and vegetable intake was measured using questionnaire items from the Behavioral Risk Factor Surveillance System. Household participation in a community garden was assessed by asking the respondent if he or she, or any member of the household, had participated in a community garden project in the last year. Generalized linear models and logistic regression models assessed the association between household participation in a community garden and fruit and vegetable intake, controlling for demographic, neighborhood participation, and health variables. Adults with a household member who participated in a community garden consumed fruits and vegetables 1.4 more times per day than those who did not participate, and they were 3.5 times more likely to consume fruits and vegetables at least 5 times daily. Household participation in a community garden may improve fruit and vegetable intake among urban adults.

Fruit and vegetable intake in African Americans income and store characteristics.

Malachy Campbell, J. Schulz, Ronald G Watkins … (2005)

The purpose of this study was to examine whether the characteristics of retail food stores where African-American women shopped mediated the association between their income and intake of fruits and vegetables. Food store characteristics included store type (supermarket, specialty store, limited assortment store, independent grocer), store location (suburbs, city of Detroit), and perceptions of the selection/quality and affordability of fresh produce for sale. The analysis drew upon data from a probability sample of 266 African-American women living in 2001 in eastside Detroit, which had no supermarkets. Structural equation modeling was used to calculate a path model of direct and indirect effects. Women shopping at supermarkets and specialty stores consumed fruit and vegetables more often, on average, than those shopping at independent grocers. More positive perceptions of the selection/quality, but not affordability, of fresh produce at the retail outlet where they shopped was positively associated with intake, independent of store type and location as well as age, per capita income, and years of education. The results suggested an indirect association between income and fruit and vegetable intake; women with higher per capita incomes were more likely to shop at supermarkets than at other grocers, which in turn was associated with intake. Previous studies have shown that few supermarkets are located in the city of Detroit, a symptom of economic divestment over the past several decades. Results of this study suggest this may have negative implications for dietary quality, particularly among lower-income women.
