Background: Ventilator dependency constitutes a major problem in the intensive care setting. Malnutrition is considered a major determinant of extubation failure, however, attention has been attracted to modulating carbon dioxide production through decreasing carbohydrate loading and increasing the percent of fat in enteral feeds. The detected interrelation between substrate oxidation and ventilation outcome became the base of several research to determine the appropriate composition of the nonprotein calories of diet in ventilated patients. Purpose: We aimed to assess the effect of high-fat dietary modification and nutritional status on ventilatory and final outcomes of pediatric intensive care. Methods: Fifty-one ventilated children (1 month to 12 years of age) with pulmonary disease who could be enterally fed, in the Cairo University Pediatric intensive care unit, were divided into 2 groups: group A included 25 patients who received isocaloric high-fat, low-carbohydrate diet; group B included 26 patients who received standard isocaloric diet. Comprehensive nutritional assessment was done for all patients. Results: Group A had a significant reduction in carbon dioxide tension, but no similar reduction in the duration or level of ventilatory support. Assisted minute ventilation was predicted by weight-for-age and caloric intake rather than the type of diet. Poor nutritional status was associated with higher mortality and lower extubation rates. Mild hypertriglyceridemia and some gastrointestinal intolerance were significant in group A, with no impact on the adequacy of energy or protein delivery. Conclusion: The high-fat enteral feeding protocol may contribute to reducing carbon dioxide tension, with mild hypertriglyceridemia and negligible gastrointestinal intolerance as potential adverse effects. Optimization of nutritional status rather than dietary modification may improve ventilatory and survival outcomes in critically ill-ventilated children.
Purpose: This study was performed to test an obesity management program for elementary school children. The program was assessed by examining its effects on the obesity, dietary attitudes, dietary habits, and exercise habits. Methods: The participants were 65 elementary school children, of which 32 were assigned for the experimental group and 33 for the control group. The experimental group received an 8 weeks obesity management program. The outcome variables were measured before and after the program. $X^2$-test and t-test were used to analyze the data. Results: After the obesity management program, the BMI and fat mass percentage in the experimental group were significantly reduced. The score for dietary attitudes and dietary habits changed in a positive direction. Conclusions: The findings from this study suggest that the obesity management program was effective in decreasing the rate of obesity and increasing the score for dietary attitudes and dietary habits. The program should be effective in the management of obesity in elementary school children.
Purpose: The purpose of this study was to identify the effects of a school-based obesity control program based on behavior modification and self-efficacy for obese elementary school children. The program was composed of strategies to modify diet and exercise habits and to increase self-efficacy. Method: The subjects were 57 obese children (experimental group = 28, control group = 29) whose Rohler index was 150 and over. The program was implemented once a week for 12 weeks from September 16 to December 12, 2003. The data was analyzed by Fisher's exact probability, $x^2$-test, t-test, and Wilcoxon Rank Sum test. Result: The Rohler index, fat mass and lean body mass of the experimental group positively changed after the intervention more than those of the control group, but there was a significant difference in the Rohler index only (t=2.06, p=.045). In addition, obesity stress significantly decreased (z=-2.86, p=.047) and dietary self-efficacy significantly increased (t=2.35, p=.023) in the experimental group than those of the control group. Conclusion: This study supports that a school-based obesity control program based on behavior modification and self-efficacy can be effective in decreasing obesity stress and increasing dietary self-efficacy. Parents, school nurses and the other support groups should be encouraged to participate from the planning stage of the program to be effective in weight control of obese elementary school children. Also school-based program should be implemented as an essential course in the curriculum, not as an elective.
The purpose of the study was to develop an internet nutritional counseling program using an expert system to assist obese people to lose weight through behavior modification. The internet counseling program for weight loss was developed by the accumulation of knowledge dealing with eating habits and exercising behaviors in expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. To accumulate knowledge into KEA, survey was performed in 150 obese people, dietitians reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaire was the same as that of the internet consulting program, and it included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. Also, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors to lose weight. Counseling was divided into two parts; a two-week part and a daily part. Two-week counseling was performed based on 4 step questionnaires, and daily counseling was done for daily food consumption and physical activity. When clients answered survey questionnaires in a counseling internet program, the recommendations on how to eat, to exercise and to deal with stress in a real time for each case, was given. In conclusion, a counseling internet program for weight reduction can be used to give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.
This study was conducted to evaluate the effects of a body weight control program with supplementation of sea tangle (20 g/day) on 22 female college students. The contents of the program for 8 weeks contained diet therapy, exercise and behavioral modification through nutrition education. Body composition, dietary habit scores, serum lipid profiles, daily nutrient intakes and the quality of life were assessed at the beginning and at the end of the program. Average age of subjects and height were 20.8 years and 161.9 cm, respectively. After 8 weeks, there were significant reductions in body weight, body fat mass, percent body fat, waist-hip ratio and BMI. The dietary habit score such as a balanced diet, regularity of mealtime, overeating, eating while watching TV or using the computer and eating salty food were increased significantly. Serum lipid levels such as total cholesterol level, LDL-cholesterol level and triglyceride level were decreased but not significantly. There were decreases in intake of energy, protein and fat and increases in intakes of dietary fiber, folic acid, calcium and potassium from the beginning to the end of the program. There were significant improvements on subcomponents of quality of life; physical functioning, general-health and vitality. The limitation of this study was the fact that there was no control group, but an overall evaluation suggests the 8-week body weight control program consisting of diet therapy, exercise and behavioral modification with supplementation of sea tangle would be helpful to improve the body composition, dietary habits, daily nutrient intakes and quality of life in Korean female college students.
The objective of this study was to evaluate college students’dietary and health behaviors in relation to their Myers-Briggs Type Indicator (MBTI) personality preferences. Dietary and health behaviors were surveyed for 444 college students who performed the MBTI personality test. Only 6.1% of the subjects regularly had three meals a day, while 27.1% ate breakfast every day. Fifty-six point nine percent of the students took less than 15 minutes to eat a meal and had the habit of eating fast. The number of food groups they ate was, on average, 2.74 and was eaten mainly at dinner. This showed that college students did not eat a large variety of foods. Eighty-two percent of the subjects drank alcoholic beverages, 21.4% smoked, and 69.3% exercised. In addition, 73.9% of them were not satisfied with their body image, but they were not eager to try weight control. There were not many significant differences between Extraversion (E)-Introversion (I), Sensing (S)-iNtuition (N), and Thinking (T)-Feeling (F) in their dietary and heath behaviors, although some gender differences existed. Significantly better dietary and health behaviors were shown in subjects preferring Judging (J) rather than Perceiving (P). There behaviors included eating breakfast, regularly eating three meals a day, smoking less, exercising more and having a lower tendency to night-eating. The personality preference of J-P could be useful index for nutritional education and counseling or behavior modification programs for obese people.
The present studies were designed to compare the effects of dietary fat sources and levels on plasma and tissue cholesterol. Changes in plasma total cholesterol and HDL-cholesterol, cholesterol concentration in aortas, liver and intestines were determined in young rats fed diets providing dietary fat as corn-oil or butter and levels as 10%, 20% or 30% of calories respectively 1) Plasma total cholesterol and HDL-cholesterol levels were little sensitive to the modification of dietary fat sources and levels. 2) Dietary cholesterol increased the levels of plasma total cholesterol and this effect was accentuated by feeding butter. But dietary cholesterol did not increase the levels of HDL-cholesterol in the butter-fed groups, but decreased in the corn-oil-fed groups. 3) Liver cholesterol concentrations were significantly higher in rats fed diets of corn-oil than those fed diets of butter. On the contrary, cholesterol concentrations of intestines were significantly higher in the butter-fed groups than the corn-oil-fed groups. However, in aortas, no significant differences were found.
Purpose: This study was designed to examine the effects of a weight control program on body weight and the sense of efficacy for control of dietary behavior in psychiatric inpatients. Methods: A quasi-experimental design was used. Data were collected from March 1 to September 30, 2007. Female mentally ill patients in closing psychiatry ward of H University Hospital participated in the study (16 persons in the experimental group and 13 in the control group). Results: The weight control program including diet therapy, exercise, education and behavior modification therapy decreased the rate of weight gain in female mentally ill patients taking atypical anti psychotics, and effectively increased a sense of efficacy for control of dietary behavior. Conclusion: Weight control program had a positive effect as a nursing intervention to decrease obesity and to increase the sense of efficacy for control of dietary behavior of psychiatric inpatients in psychiatric inpatients.
Genetic factors clearly play a role in carcinogenesis, but migrant studies provide unequivocal evidence that environmental factors are critical in defining cancer risk. Therefore, one may expect that the lower availability of substrate for biochemical reactions leads to more genetic changes in enzyme function; for example, most studies have indicated the variant MTHFR genotype 677TT is related to biomarkers, such as homocysteine concentrations or global DNA methylation particularly in a low folate diet. The modification of a phenotype related to a genotype, particularly by dietary habits, could support the notion that some of inconsistencies in findings from molecular epidemiologic studies could be due to differences in the populations studied and unaccounted underlying characteristics mediating the relationship between genetic polymorphisms and the actual phenotypes. Given the evidence that diet can modify cancer risk, gene-diet interactions in cancer etiology would be anticipated. However, much of the evidence in this area comes from observational epidemiology, which limits the causal inference. Thus, the investigation of these interactions is essential to gain a full understanding of the impact of genetic variation on health outcomes. This report reviews current approaches to gene-diet interactions in epidemiological studies. Characteristics of gene and dietary factors are divided into four categories: one carbon metabolism-related gene polymorphisms and dietary factors including folate, vitamin B group and methionines; oxidative stress-related gene polymorphisms and antioxidant nutrients including vegetable and fruit intake; carcinogen-metabolizing gene polymorphisms and meat intake including heterocyclic amins and polycyclic aromatic hydrocarbon; and other gene-diet interactive effect on cancer.
Purpose: This study aimed to evaluate the impact of a lifestyle modification program on menstrual irregularity among overweight and obese women with polycystic ovarian syndrome. Methods: A quasi experimental research design was used to conduct this study on 82 women with polycystic ovarian syndrome at the Gynecology and Obesity clinics of Mansoura University Hospital, Egypt. Two groups were included; the study group received a lifestyle modification program for 48 weeks, while the control group was not subjected to this program. Data collection was done for the following variables, a structured interview questionnaire was used to assess the women's general characteristics, menstrual patterns, and 24-hour dietary recall and the researcher took anthropometric measurements and assessed hirsutism by the Ferriman-Gallwey scale. Results: After one year of lifestyle modification, the number of menstrual cycles significantly increased from $2.7{\pm}1.6$ to $6.9{\pm}1.5$ (t=12.26, p<.001) in the study group compared to insignificant minor changes among the control group (t=0.69, p=.488). Additionally, 58.5% were menstruating regularly compared to none in the control group (${\chi}^2=33.93$, p<.001). Conclusion: Participating in a lifestyle modification program was effective in reducing menstrual cycle's irregularity among overweight and obese women with PCOS. Thus, it is recommended to motivate the nurses in counseling the PCOS women on lifestyle modifications.
