Pedraza, Dixis Figueroa;
Revista Brasileira de Saúde Materno Infantil , 2005, DOI: 10.1590/S1519-38292005000300013
Abstract: the more exposed people to food and nutritional insecurity comprise the list of the "dispossessed". the most affected families are the ones more vulnerable to environment degradation, living in bad sanitary conditions, contamination and high demographic rates; when this is associated to the maternal and children group vulnerability becomes more accentuated. the quantification of malnourished and undernourished people is as important as determining who they are, where they are, their food habits and the causes and solutions for the problem. our definition of possible vulnerable groups in brazil follows two perspectives: poverty related data and fao's vulnerable group classification (perspectives containing personal criteria, for there are no approaches of the type in scientific literature). high income concentration in brazil results that the poor have insufficient resources to buy food implying in more vulnerability. there are differences between: urban and rural areas, metropolitan and non-metropolitan areas, and between the northeast and northern regions as related to other regions. there are important ethnic, cultural and migration factors involving the more vulnerable groups.

Estado nutricional como factor y resultado de la seguridad alimentaria y nutricional y sus representaciones en Brasil
Pedraza,Dixis Figueroa;
Revista de Salud Pública , 2004, DOI: 10.1590/S0124-00642004000200002
Abstract: we approach the determining factors and results of food and nutritional security in brazil. the following aspects are considered: i. the concept to be studied; ii, the form of measuring a particular factor; iii. a brazilian characterization on the subject, and iv. conclusions. nutritional status is primarily a result of the balance between the needs and the spending of food energy and other essential nutrients and, secondarily, of multiple determinants in a given space, represented by physical, genetic, biological, cultural, psycho-socio-economic and environmental factors. according to this, there are 3 basic causes of nutritional disorders: food, health and care. because the repercussions of the economic changes on the nutritional status are not immediate, food security is only one factor of nutritional status and because subjects adapt differently to low food intake, the most adequate nutritional indicators in studies of food and nutritional security are the childhood indicators and the indicators of historical trends. the interpretation of nutritional indicators poses 3 main problems: to determine if the problem is really one of food security; to establish the degree of importance of the problem, and to determine which could be the appropriate normative intervention. the studies of nutritional status in brazil show considerable improvement in the anthropometric indicators, emphasizing that the worst conditions prevail in the north east region and in the rural areas. regarding micronutrient deficiencies, the absence of nationwide studies and the great advances in the programs to tackle this deficiencies, mainly vitamin a and iodine deficiencies are highlighted.

Pedraza, Dixis Figueroa;
Revista de Nutri??o , 2005, DOI: 10.1590/S1415-52732005000100012
Abstract: to discuss the availability of food in brazil, based on, and associating to data from scientific literature. this is the first of six articles, discussing the determining factors and the resulting ones of food and nutritional security, and brazil's conditions related to them. the same pattern is observed in all articles, considering: (i): the concept/factor to be studied, (ii): the form to measure that factor; (iii): a brazilian characterization on the subject; (iv): global and interrelated conclusions; (v): final considerations, leading to the factor's implications in important strategies that should be formulated. brazil is a country in which food availability does not constitute a limiting factor of its food and nutritional security. in spite of this, the sustainability of food availability and the inequality are factors that are jeopardizing the national nutritional system.
Obesidad y pobreza: marco conceptual para su análisis en latinoamérica
Pedraza, Dixis Figueroa;
Saúde e Sociedade , 2009, DOI: 10.1590/S0104-12902009000100011
Abstract: obesity has a multifactorial etiology in which the most important factors are related to lifestyle. high prevalence of obesity is basically caused by important changes in nourishment, in the pattern of physical activity and by other sociocultural factors, which have produced a nutritional transition process. due to the trends of increase and of social differences in obesity, the minorities and populations with lower educational and socioeconomic level can be the most affected groups. in poor people, obesity is associated, among others, with malnutrition episodes in childhood, even during intrauterine life, and also with alimentary, sociocultural and gender factors. the relationship between obesity and socioeconomic condition is very changeable and complex, since the association is different in distinct socioeconomic contexts and it may remain hidden by several factors (physical exercise, diet, psychological factors, heredity, sociocultural factors) that influence the association. the socioeconomic level might determine the presence of obesity, and obesity, in turn, might cause social consequences to the individual (if social mobility is the most relevant factor, obesity is the one that would determine the individual's social position). the arguments proposed here are sufficient to justify the importance of the problem in latin america. thus, it must represent a challenge, principally for researchers and decision makers, translatable in prioritizing obesity in poverty conditions.

Epidemiology and health services evaluation
Dixis Figueroa Pedraza
Revista Brasileira em Promo??o da Saúde , 2011,
Abstract: Objective: To discuss the application of Epidemiology in health services evaluation. Data synthesis: The contribution of Epidemiology in health services evaluation occurs mainly in the selection, construction and analysis of indicators and the assessment of performance and impact. Two basic axes guide health services evaluation: the type of indicator used and the degree of inference needed to conclude whether the results are due or not to intervention.The type of indicator to be used depends, essentially, on what is being measured, the process, the outcome or both. According to the degree of causal inference, there are three types of evaluation: adequacy, plausibility and probability. This paper presents the designs of studies that can be used in the evaluation of health services according to the degree of inference. Considering the conditions in which health services are structured and proceed, the studies of adequacy and plausibility are more convenient to evaluate the performance and impact of health services. Conclusions: There are still important methodological problems that must be overcome in the impact assessment of public health interventions. These problems include the difficulty associated with randomization, obtaining control groups for confounding factors and the choice of relevant indicators of process and outcome.
