A study was conducted to investigate and compare the nutritional status and physical work performance of children of Brazilian migrant agricultural workers with Brazilian children from wel1-to-do backgrounds. The relationship between nutritional status and physical work performance was also investigated. Dietary analysis was conducted using the 24-hour diet recall method. Evidence was found that intakes of energy, calcium, thiamin, riboflavin, niacin, and vitamin C may have been inadequate among migrant worker children. Their diet was generally monotonous and consisted mainly of rice, beans, and coffee with sugar. Diets of well-to-do children were considerably more varied with good representation from all major food groups. Anthropometric assessment indicated that migrant worker children had values for weight and triceps skinfold thickness that were low compared to American standards. Values for height, arm circumference, and arm muscle circumference were average compared to American standards. Well-to-do children exceeded American standards for all anthropometric parameters measured. Biochemical investigations of protein and iron status were also conducted. Serum total protein and albumin levels were normal in most subjects in both groups. However, many migrant worker, children had low values for hematocrit, serum iron, and transferrin saturation. Most well-to-do children had normal values for these parameters. Hemoglobin levels were adequate in most subjects. Physical work performance was found to be impaired in migrant worker children. Exercise heart rates and post-exercise blood lactic acid levels in response to a standardized bicycle-ergometer work test were significantly higher in migrant worker compared to wel1-to-do children. In addition, a significant correlation was found between anthropometric indicators of nutritional status and parameters of physical work performance. Finally, socio-economic and ecological assessment indicated that the living conditions of migrant worker children were impoverished and unsanitary. This probably aggravated health problems such as infections that were found to occur among these children. Well-to-do children did not share these conditions. / Land and Food Systems, Faculty of / Graduate

In this analysis, we plan on developing vegetable mixes with high nutritional qualities and instant fuel consumption. These are to be used as a nutritional supplement in the feeding of children from 6 months of age. Initially, I selected the raw material, due to its high protein content and low cost (soy, tarhui, Cuban corn, rice, wheat, barley). They formed mixes with nutritional characteristics similar to the control for reference (15.5% of protein, 419 kcal of energy). From these formulas, different tests of completed production of mixtures, going so far as to obtain eight mixes with good nutritional and organoleptic characteristics. The eight mixes and the control for reference were subjected to sensory analysis tests (sensory quality test and acceptability and preference test), Of these mixes, 4 were selected (WA1, WA2, WA5 and the control for reference WA7) such as finished women mixtures. The same groups were subjected to a bromatologic analysis and biological tests with animals from the laboratory. Finally, the study of industrial viability of a small processing plant of instant vegetable mixtures was conducted.

The study conducted in the rural area of the province of Imbabura included a total of 518 families that when compared with the estimated sample of 96%, 42.7 % corresponding to the indigenous ethnic group, 28.15% to Black and 25% to mixed-race ethnic groups, these differences of involvement between ethnic groups is due to the fact that the indigenous population is greater than the two remaining populations. Of the 518 families studied they were able to obtain a total of 794 children younger than 5, in which 48.5% pertaining to the male sex and 51.4% to the female sex. In linking the number of participating families and the number of children studied we were able to find that mothers have 1 to 2 children younger than the age of 5 in every family. In evaluating the nutritional state of the 794 studied children, 47.09% were found to have global malnutrition (P/E), 67.26% presented a chronic malnutrition that is to say a lower height for their age, whereas 13.97% presented an acute malnutrition, a percentage that doesn’t attract attention due to what I have already noted previously with children presenting low height and weight for their age when using the indicated weight/height, the nutritional state of the children is appropriate. The nutritional state of children under the age of 5, by considering the indicators of weight/age and height/age, identified the indigenous ethnicity having major problems of malnutrition (54% and 80.97%) respectively, while the two remaining ethnic groups have presented similar percentages. The opposite occurs with the indicator of weight/height, which detected that the Black ethnic group presented a major nutritional deterioration (24%) unlike the other two ethnic groups, we believe that this difference is due to indigenous children presenting a diminished height, consequently when we use the indicator of weight/height, an adequate weight for height is presented. According to the magnitude of diarrheal processes we find that 28.34% of children presented EDA, the indigenous ethnicity being that with the highest percentage (12.84%) in relation to the other two ethnic groups. According to the severity of the diarrheal processes, light EDA presents the highest percentage with 62.67%, with the indigenous ethnicity being affected the most, moderate EDA presents a 34.22% similarly affecting the indigenous ethnicity and severe EDA presents a 3.11% with the mixed-race ethnicity being the most affected. Relating the nutritional state with acute diarrheal illnesses, considering the indicators of weight/age and height/age, we find that the indigenous population is mostly affected in nutritional state as well as in the presence of EDA. Malnourished children present a higher number of diarrheal processes. Considering the indicator of weight/height, diarrhea is more frequent in children with a normal nutritional state, with the Black ethnicity that which presents the greater percentage of EDA in normal and malnourished children. For this reason, it is urgent that national programs of health and alimentation are defined and implemented in order to combat the nutritional problem and ensure an adequate supply of food for the whole population, improving the conditions of health and environmental sanitation in order to reduce the high rates of malnutrition, diarrhea and acute respiratory infections.

This research addressed malnutrition in the villages of Topo, Imbabura, Gualabí, Calpaquí and Compañía in the city Otavalo, which is in the Province of Imbaura, Ecuador. The research determined the effects of consumption of small-animals on the diet and hemoglobin levels in school aged boys and girls. This study involved 311 indigenous children between 6 and 12 years of age. Following parental authorization, blood tests and fecal samples were taken from each child to analyze hemoglobin and parasites. Additional information gathered from this study group included a socio-economic survey, frequency of food consumption, 24 hour inventory, animal production, and basic knowledge on anemia to compare the results with the normal standards. The results showed prevalent anemia, poor nutritional conditions, parasite presence, dietary iron deficiencies, and low school performance. Recommendations from these results include using dietary iron supplements and deworming children. This information increases community knowledge of the nutritional conditions of school children and how to improve these situations in general.

The rural communities of the province of Imbabura present multiple problems of environmental, educational, and economic kind. Previous studies show that the rural communities of the Ecuadorian population present serious problems of health and nutrition, among those that excel are: poliparasitosis, respiratory infections and diarrheal, malnutrition, deficiency of micro nutrients, sanitary deficiency, scarce economic resources and low level of instruction. All these factors have caused a decrease in the productive capacity of the country and affected their level of development. In addition, delay exists in size in the students, which leads to a decrease in the capacity for physical work, alterations of mental development and frequent repetitions of the school grade. The malnutrition is a product of biological, social and environmental factors directly influence good health, intellectual development and academic performance. In the province of Imbabura, there is no up to date information relating to diet, nutrition and some aspects of the health of the students. Therefore it has been considered important to perform a food, nutritional and health diagnosis that contributes to the planning and development of actions that will improve the situation.

The present study assessed the relationship between the paternal use of food in a contingency manner and the physical status of the respective son. The prevalence of childhood obesity has been documented to be significant in this country (Mayer, 1968; Collipp, 1975; Forbes, 1975; Hafen, 1981). The etiology of the increasing percentages of obese children is based upon a variety of variables. Parental influence on children's eating habits and socioeconomic variables, which influence parents, appeared to be possible factors in the development of childhood obesity. / Master of Science
