Public Health Risk-Benefit Assessment in Foods : methodological development with application to infant milk-based diet / Evaluation des risques-bénéfices de santé publique liés à l'alimentation : développement méthodologique et application à l'alimentation en lait des nourrissons

Boué, Géraldine 04 July 2017 (has links)
L’objectif de cette thèse était de développer un cadre conceptuel et méthodologique permettant d’évaluer l’impact global de l’alimentation sur la santé des consommateurs, en prenant en compte les dimensions microbiologiques, chimiques et nutritionnelles. Cette méthodologie a été développée à l’aide d’un cas d’étude portant sur l’alimentation des nourrissons (lait maternel et formules infantiles), incluant les facteurs suivants : C. sakazakii, Cryptosporidium, arsenic, polychlorobiphényles de type dioxine et acide docosahexaénoïque. Cinq modèles mathématiques probabilistes ont été développés pour quantifier les risques / bénéfices associés à chaque facteur. Ils ont été ensuite harmonisés, quand cela a été possible, à l’aide d’un indicateur commun de santé publique, le DALY. Les résultats ont été obtenus par simulation de Monte Carlo de second ordre afin de quantifier séparément l’incertitude et la variabilité. Les techniques probabilistes ont permis de prendre en compte d’une part la variabilité inhérente à la biologie (hétérogénéité entre individus d’une même population) et d’autre part l’incertitude liée au manque de connaissances et de données. De plus, la séparation de la variabilité et de l’incertitude a consolidé l’évaluation, permettant une interprétation plus cohérente des résultats et donc fournissant des informations plus complètes aux décisionnaires. La méthode mise en oeuvre dans ce travail de thèse pourra servir de base pour d’autres cas d’études et pourra aussi être utilisée pour continuer le développement méthodologique de l’évaluation risque-bénéfice. Cette démarche s’inscrit dans une approche plus générale d’analyse multi-critères des systèmes agronomiques et alimentaires / The objective of the present PhD project was to develop a conceptual and methodological framework to assess the overall impact of food consumed on human health, including microbiological, chemical and nutritional dimensions. This methodology was developed using a case study on infant milk-based diet (breast milk and infant formulas) taking into account the following selected factors: C. sakazakii, Cryptosporidium, arsenic, dioxin like polychlorinated biphenyls and docosahexaenoic acid. Five probabilistics mathematicals models were developed to quantify risks / benefits associated with these factors. When possible, they were harmonized using a common public health indicator, the DALY. Results were obtained by second-order Monte Carlo simulations in order to quantify separately the uncertainty and the variability. Probabilistic techniques enabled to take into account on the one hand the biology related to variability (heterogeneity between individuals of the same population) and on the other hand the uncertainty linked to the lack of knowledge and data. In addition, separation of variability and uncertainty strengthened the evaluation by enabling a more accurated interpretation of results and by providing more comprehensive information for policy makers. The method used in this PhD thesis can be considered as a robust basis for other case studies and can be also used to continue methodological development in risk-benefit assessment. This approach is also part of a broader area: the multi-criteria decision analysis of agronomic and food systems

Segmentace trhu kojeneckých mlék / Segmentation of Infant Milks Market

Čevela, Josef January 2012 (has links)
The principal goal of the master thesis is to explore the similarities and possible differences among customers of infant milks. Based on those findings, the customers are clustered into various segments, which are extremely homogenous within each one, but significantly heterogeneous outside each of them. The second goal of the thesis is to suggest the best marketing solutions for each revealed segment. The work is divided into two parts, theoretical and practical. The theoretical part describes the process of market segmentation. The characteristics of the infant milk market and the description of infant milk types are described in the practical part. The customers' segmentation is designed according to primary and secondary research. Secondary data is based on data from project MML-TGI and content analysis. The data from my own primary research are processed by IBM SPSS statistics version 20. Among the main finding of the thesis was defining 5 segments of the infant milk customers. The work characterizes all of them and special term is chosen for each of the segment. Finally, the relevant marketing solutions are suggested for each of the segment.
