Item Food intake in patients on hemodialysis(2014-12) Vaz, Inaiana Marques Filizola; Freitas, Ana Tereza Vaz de Souza; Peixoto, Maria do Rosario Gondim; Ferraz, Sanzia Francisca; Campos, Marta Isabel Valente Augusto MoraesObjective To evaluate the intake of energy and nutrients by individuals on hemodialysis, following especific recommendations for this population and according to Food Guide for the Brazilian Population. Methods A cross-sectional study, 118 adult patients, considered stable from, ten dialysis centers in Goiânia, Goiás. Dietary intake was estimated by six 24-hour recalls, and classified as adequate or inadequate, according to specific recommendations for individuals undergoing dialysis and that recommended for a healthy diet. A descriptive analysis was performed. Results Average dietary intake of 2022.40 ± 283.70 kcal/day; 31.18 kcal/kg/day; 55.03 ± 4.20% carbohydrate; 30.23 ± 3.71% lipid, 1.18 ± 0.23 g protein/kg/day. Important prevalences of inadequacy were observed for the intake of calories (39.0%), protein (39.0%) and other nutrients such as retinol (94.9%), saturated fat (87.3%), cholesterol (61,9%), iron (61.0%), potassium (60.2%) and zinc (45.0%). Patients had a low intake of fruit food group (1.22 ± 0.89 servings) and vegetables (1.76 ± 1.01 servings), dairy products (0.57 ± 0.43 servings) and high intake of food group of oils and fats (3.45 ± 0.95 servings), sugars and sweets (1.55 ± 0.77 servings). Conclusion Observed food consumption imbalance, characterized by excess of oils and fats, especially saturated oils and cholesterol, sugars and sweets, parallel to low intake of fruits and vegetables and dairy products. A considerable percentage of patients did not intake the minimum recommended of calories, protein, retinol, iron, zinc and potassium.Item A ingestão energética de pacientes em hemodiálise é subrelatada?(2015-09) Vaz, Inaiana Marques Filizola; Freitas, Ana Tereza Vaz de Souza; Peixoto, Maria do Rosario Gondim; Ferraz, Sanzia Francisca; Campos, Marta Isabel Valente Augusto MoraesIntroduction: Underreporting of energy intake is not much studied in hemodialysis population. Objective: To evaluate the underreporting of energy intake and associated factors in hemodialysis patients. Methods: A cross-sectional study, with 344 patients stable adults, of ten hemodialysis centers in Goiânia-GO. Energy intake was assessed by six 24-hour dietary recalls and basal metabolic rate (BMR) was estimated using the Harris Benedict equation. It was considered as underreporting when the ratio between the average energy intake and basal metabolic rate was lower than1.27. For analysis of factors associated with underreporting, the Poisson regression with robust variance estimation was applied. Results: The prevalence of underreporting was 65.7%, being more significant in individuals who are overweight and in the non dialysis days. The result of the multivariate analysis identified four factors independently associated with the underreporting: being a female (PR = 1.27, CI = 1.10 to 1.46), body mass index ≥ 25 kg/m2 (PR = 1.29, CI = 1.12 to 1.48), three meals or lower/ day (PR = 1.31, CI = 1.14 to 1.51) and hemodialysis length lower than 5 years (PR = 1.19CI = 1.01 to 1.40). Conclusion: The population showed a high prevalence of underreporting of energy intake. Being a female, presenting overweight, lower number of meals/day and lower length time on hemodialysis were factors associated with underreporting.Item Prevalence of malnutrition and associated factors in hemodialysis patients(2014-06) Freitas, Ana Tereza Vaz de Souza; Vaz, Inaiana Marques Filizola; Ferraz, Sanzia Francisca; Peixoto, Maria do Rosário Gondim; Campos, Marta Isabel Valente Augusto MoraesObjective To assess the prevalence of malnutrition and associated factors in hemodialysis patients. Methods This is a cross-sectional study of 344 hemodialysis patients from Goiânia, Goiás aged 18 years or more. The dependent variable, malnutrition, was investigated by the Subjective Global Assessment. The independent variables included socioeconomic, demographic, and lifestyle data, clinical history, and energy and protein intakes. The patients underwent anthropometric measurements and laboratory tests. Multiple Poisson regression determined the associated factors (p<0.05). Results Mild or moderate malnutrition was found in 22.4% of the patients. Malnourished patients had lower body mass index, mid-arm muscle circumference, percentage of body fat, serum creatinine (p<0.001), and normalized protein nitrogen appearance (p=0.001). Multivariate analysis identified the following factors associated with malnutrition: age between 19 and 29 years (PR=1.23, 95%CI=1.06-1.43), family income less than 2 minimum salaries (PR=1.13, 95%CI=1.01-1.27), hemodialysis vintage ≥60 months (PR=1.08, 95%CI=1.01-1.16), Kt/V≥1.2 (RP=1.12, 95%CI=1.03-1.22), calorie intake <35 kcal/kg/day (PR=1.22, 95%CI=1.10-1.34), and normalized protein nitrogen appearance <1.0 g/kg/day (PR=1.13, 95%CI=1.05-1.21).Conclusion The prevalence of malnutrition in this population was high, corroborating the literature. The prevalence was higher in patients aged less than 29 years and those with low family income, longer hemodialysis vintage, higher Kt/V, and inadequate protein and calorie intakes. Strategies to reverse this situation should include more nutritional care.Item Prevalência e fatores associados à obesidade abdominal em pacientes em hemodiálise em Goiânia - GO(2013) Freitas, Ana Tereza Vaz de Souza; Vaz, Inaiana Marques Filizola; Ferraz, Sanzia Francisca; Peixoto, Maria do Rosario Gondim; Campos, Marta Isabel Valente Augusto Moraes; Fornés, Nélida Antonia Schmid deIntroduction: The presence of excess weight, especially visceral obesity contributes to the increased risk of metabolic and cardiovascular complications in patients with chronic kidney disease. Objective: To determine the prevalence and associated factors with abdominal obesity in patients on hemodialysis (HD). Methods: Cross-sectional study with 344 patients older than 18 years. Abdominal obesity was defined as waist circunference ≥ 94 cm in men and ≥ 80 cm in women. The independent variables involved socioeconomic, demographic, lifestyle, duration of HD, food consumption and body mass index (BMI). The analysis of associated factors was performed by multiple Poisson regression, remaining in the final model variables with p < 0.05. Results: The prevalence of abdominal obesity was 44.77% and was more prevalent in women (55.71%) than in men (37.25%), p = 0.001. The end result of the multivariate analysis identified factors associated with abdominal obesity in men and women: age over 40 years, protein intake below 1.2 g/kg/day and BMI ≥ 25 kg/m². In men the economic class D/E remained associated with abdominal obesity, p < 0.05. Conclusion: There was a high prevalence of abdominal obesity in hemodialysis patients. Age greater than 40 years, lower socioeconomic classes, below the recommended protein intake and overweight were associated with abdominal obesity.
