Furthermore, the relationship between the nutritional health status of participants andcropping and dietary diversity was analysed.The study was carried out during three different seasons within one year (2006/2007) in 18villages of three districts in north-eastern and central Tanzania including 252 women. The surveyincluded an individual interview on vegetable production, food consumption (i.a. 24h-recall, 7drecallon vegetables) and nutritional knowledge, and the measurement of body mass index (BMI),haemoglobin (Hb) for iron status and different parameters for vitamin A status. Besides studyingsingle nutrients, food groups and health problems, also a more holistic view was taken on dietarydiversity/food variety and dietary patterns and their relationships with nutritional status andvegetable production. Relationships were investigated both through bivariate correlations andmultiple regression analysis dietary diversity and food variety scores were calculated and dietarypatterns were generated through principal component analysis (PCA) as well as cluster analysis.Regarding the link between production and consumption, there was a clear relationship betweenvegetable diversity produced and diversity consumed, while this was not so clear betweenproduction and consumption quantity, except for single seasons. Influencing factors on consumedvegetable quantity were suggested to be seasonality the purchase of additional vegetables(especially exotic) next to home-grown ones and knowledge, attitudes and preferences of womenregarding vegetable consumption. When analysing food patterns, no direct association betweendiversity of vegetable cropping and vegetable consumption was established. Yet, for the studypopulation in Tanzania it was found that food consumption was (still) influenced by localproduction and that, therefore, food consumption issues should always integrate existing foodproduction and vice versa.The link established between food consumption and nutritional health data of the present studyshowed that the obesity epidemic is on the rise, even in rural, poor and underdeveloped regionsof Tanzania. Furthermore, it was found that a high dietary diversity is not per se a guarantee for ahealthy diet, yet, food types and food groups that contribute to a high diversity are decisive. Adirect link between production and nutritional health could only partly be shown. Obviously, thefocus on vegetable production seems to be not sufficient, but overall food production needs to betaken into account.Further recommendations for future research are, i.a., to investigate the influence of exoticvegetables and, generally, exotic foods in production and consumption on nutritional health toenhance dietary diversity scores as a tool for assessing dietary diversity together with dietaryquality to eleborate dietary guidelines for Tanzania, preferably district- or area-wise to investigatethe nutrition transition in Tanzania especially in rural areas with a focus on the nutritionalknowledge of people, their attitudes, preferences (e.g. taste) and behaviour Hersteller: Cuvillier Verlag Marke: Cuvillier Verlag EAN: 9783869555980 Kat: Hardcover/Naturwissenschaften, Medizin, Informatik, Technik/Biologie/Landwirtschaft, Gartenbau, Forstwirtschaft, Fischerei, Ernährung Lieferzeit: Sofort lieferbar Versandkosten: Ab 20¤ Versandkostenfrei in Deutschland Icon: https://www.inforius-bilder.de/bild/?I=MU1St5Oau97Akfo1rtwQrqO6D2G13EgYc%2Fy5g2CexBU%3D Bild:
