RESUMO

BACKGROUND & AIM: Oropharyngeal dysphagia (OD) can lead to a deficiency of antioxidant micronutrients. The aim of the present study was to investigate the relation between OD and nutritional status, antioxidant vitamins (ß-carotene, vitamin E and C) and serum markers of the inflammatory response [C-reactive protein, myeloperoxidase (MPO), nitric oxide metabolites (NOx), tumor necrosis factor-α, interleukin (IL)-1ß and IL-6] in adults and elderly. METHODS: A cross-sectional study was conducted with 69 individuals: 22 in the control group (CG) and 47 in the OD group (ODG). The ODG was subdivided into ODG-mild = normal oral feeding (OF, n = 14), ODG-moderate (OF-modified, n = 22) and ODG-severe (OF-suspended, n = 11). Associations were investigated using multiple linear regression. RESULTS: The body mass index (BMI) was higher in the ODG compared to the CG (p = 0.008), independently of sex, age, energy intake (EI) and score on the Functional Independence Measure. BMI was significantly lower in the ODG-severe compared to the ODG-mild (p = 0.012). OD was associated with lower concentrations of ß-carotene (p < 0.001) and vitamin C (p < 0.001), independently of sex, age and EI, and higher concentrations of MPO (p = 0.008) and NOx (p = 0.011), independently of sex, age and the presence of comorbidities. CONCLUSION: Adults and elderly with OD have lower levels of antioxidant vitamins (ß-carotene and vitamin C) and a high inflammatory response (MPO and NOx). The evaluation of antioxidant vitamins could be incorporated in nutritional status assessment in this population.

RESUMO

BACKGROUND & AIMS: Oropharyngeal dysphagia (OD) and comorbidities can exert an influence on nutritional status and contribute to mortality. The aim of the present study was to examine relationships between high Charlson Comorbidity Index (CCI) scores and OD outcomes, including OD severity, feeding route, nutritional status and one-year mortality rate in adults and elderly individuals. METHODS: A longitudinal study, whose the final sample comprised 110 patients with OD and 75 of whom were evaluated for one-year mortality outcome. Swallowing (videofluoroscopy), nutritional status [body mass index (BMI)], CCI, type of feeding route, medications and hospitalization were evaluated. Multinomial logistic regression was performed to calculate the unadjusted and adjusted odds ratios (OR) and 95% confidence intervals (95%CI). RESULTS: Overall sample of the study were adults and elders with a median age (years) of 61.3 [interquartile range (IQR): 58.4-64.2]. The median CCI was 2.3 (IQR: 2.1-2.6) and the mortality rate was 10.8%. Hospitalization was significantly associated with underweight (p = 0.013) and number of medications (p = 0.023). After adjustment, sex/age and nº-Medications/Hospitalization (nº-M/H), CCI ≥3 was associated with nasogastric tube feeding (OR 4.57, 95%CI 1.59-13.1 and OR 3.39, 95%CI 1.21-9.51 respectively) and swallowing performance (OR 0.73, 95%CI 0.59-0.90 and OR 0.74, 95%CI 0.61-0.90 respectively). CONCLUSIONS: A high CCI was associated with OD severity and feeding route, but not with nutritional status or mortality.

RESUMO

BACKGROUND & AIMS: The relationship between vitamin D and oropharyngeal dysphagia (OD) is still poorly understood. The aim of this study was to evaluate 25-hydroxyvitamin D [25(OH)D] concentration in patients with OD and to verify its association to nutritional status, functional independence measure (FIM), time of clinical signs (TCS) and OD severity. This is a cross-sectional study conducted with outpatients. Body mass index (BMI), FIM, TCS, causes of OD, comorbidities, penetration-aspiration scale (PAS) and severity scale were evaluated. METHODS: A multiple linear regression and effect size were performed to evaluate the association between serum 25(OH)D concentration and independent variables. RESULTS: Forty-eight participants were included, with a mean age of 60.1 ± 15.3 years. The mean of the 25(OH)D concentration was 26.10 ± 12.0 ng/mL. The prevalence of hypovitaminosis D (<30 ng/mL) was 73%. In the multiple linear regression analysis (adjusted for sex, age, BMI, dietary intake and solar radiation), 25(OH)D concentration was significantly related with the TCS (p = 0.01, f2 = 0.48). Patients with hypovitaminosis D had a moderate effect (p = 0.08, δ = 0.36) for a lower FIM score. CONCLUSIONS: These findings indicate that serum 25(OH)D concentration may be related to the TCS and the functional capacity of patients with OD.

RESUMO

The aim of the present study was to evaluate the effect of cystic fibrosis and antibiotic therapy on intestinal microbiota composition and intestinal inflammation in children and adolescents. A cross-sectional controlled study was conducted with 36 children and adolescents: 19 in the cystic fibrosis group (CFG) and 17 in the control group (CG) matched for age and sex. The CFG was subdivided based on the use of antibiotic therapy (CFAB group) and non-use of antibiotic therapy (CFnAB group). The following data were evaluated: colonization, antibiotic therapy, mutation, breastfeeding, use of infant formula, type of delivery, introduction of solid foods, body mass index, fecal calprotectin and intestinal microbiota composition (fluorescence in situ hybridization). Intestinal inflammation evaluated by fecal calprotectin was significantly higher in the CFG (median: 40.80 µg/g, IQR: 19.80-87.10, p = 0.040) and CFAB group (median: 62.95 µg/g, IQR: 21.80-136.62, p = 0.045) compared to the CG (median: 20.15 µg/g, IQR: 16.20-31.00), and the Bacteroides, Firmicutes, Eubacterium rectale and Faecalibacterium prausnitzii were significantly decreased (p < 0.05) in the CFG compared to the CG, whereas the bacteria Clostridium difficile, Escherichia coli and Pseudomonas aeruginosa were significantly increased in the CFG (p < 0.05). The main differences were found between the CG and CFAB group for Eubacterium rectale (p = 0.006), Bifidobacterium (p = 0.017), Escherichia coli (p = 0.030), Firmicutes (p = 0.002), Pseudomonas aeruginosa (p < 0.001) and Clostridium difficile (p = 0.006). The results of this study confirm intestinal inflammation in patients with CF, which may be related to changes in the composition of the intestinal microbiota.

RESUMO

RESUMO Objetivo: Avaliar a associação entre estado nutricional, função pulmonar e morbidade em coorte de 36 meses de crianças e adolescentes com fibrose cística (FC). Métodos: Coorte prospectiva de 36 meses, com crianças e adolescentes com FC e idade entre 1 e 15 anos. No tempo inicial, o estado nutricional foi determinado a partir dos indicadores: peso-para-estatura e índice de massa corporal-para-idade, para crianças <2 anos e ≥2 anos, respectivamente, e classificado em: falência nutricional, risco nutricional e estado nutricional aceitável; também foi determinado por meio do percentil 50°, de acordo com a curva de crescimento da World Health Organization (WHO). A função pulmonar foi avaliada pelo volume expiratório forçado no primeiro segundo (VEF1). A morbidade foi determinada pela presença de infecção e hospitalização por exacerbação pulmonar. Foi calculado risco relativo (RR) e intervalo de confiança (IC95%), considerando significante p<0,05. Resultados: Foram avaliadas 38 crianças e adolescentes (mediana de idade 3,8 anos). Os pacientes classificados em falência nutricional no início do estudo mostraram um RR de 5,00 (IC95% 1,49; 16,76) para o comprometimento da função pulmonar após 36 meses. Aqueles classificados abaixo do percentil 50° apresentaram RR de 4,61 (IC95% 0,89; 23,81) para o desfecho. O estado nutricional não foi fator de risco para morbidade. Conclusões: O déficit nutricional esteve associado ao comprometimento da função pulmonar, mas não com a morbidade em crianças e adolescentes com FC.


ABSTRACT Objective: To evaluate the association between nutritional status, lung function and morbidity in a 36-month cohort in children and adolescents with cystic fibrosis. Methods: Prospective cohort of children and adolescents with cystic fibrosis aged 1-15 years. At the baseline, the nutritional status was determined by weight-for-height and body mass index-for-age for children <2 years and ≥2 years, respectively, and classified as: nutritional failure, nutritional risk and acceptable; and by the 50th percentile, according to the World Health Organization (WHO) growth charts. Lung function was assessed by forced expiratory volume in one second (FEV1). Morbidity was determined by the presence of infection and hospitalization by pulmonary exacerbation. Risk ratio and 95% confidence interval (95%CI) were calculated, being significant when p<0.05. Results: We evaluated 38 children and adolescents (median age 3.8 years). Patients that were classified as having nutritional failure at baseline had a RR of 5.00 (95%CI 1.49; 16.76) to present impaired lung function after 36 months. Those classified bellow the 50th percentile had a RR of 4.61 (95%CI 0.89; 23.81) to present the same outcome. Nutritional status was not a risk factor for morbidity in this cohort. Conclusions: Nutritional deficit was associated with impaired lung function, but not with morbidity in children and adolescents with cystic fibrosis.

RESUMO

ABSTRACT BACKGROUND: Chronic lung infections, inflammation and depletion of nutritional status are considered to be prognostic indicators of morbidity in patients with cystic fibrosis. The aim of this study was to investigate the association between inflammatory markers and lung function, nutritional status and morbidity among children/adolescents with cystic fibrosis. DESIGN AND SETTINGS: Prospective three-year longitudinal study conducted in an outpatient clinic in southern Brazil. METHODS: Children/adolescents aged 1-15 years with cystic fibrosis were enrolled. Nutritional status was determined from weight-to-length and body mass index-to-age z-scores and was classified as acceptable, at risk or nutritional failure. Tumor necrosis factor-α, interleukin-1β, myeloperoxidase, C-reactive protein and C-reactive protein/albumin ratio were analyzed. Lung function was evaluated based on the forced expiratory volume in the first second and morbidity according to the number of hospitalizations for pulmonary exacerbation and infections by Pseudomonas aeruginosa. Lung function, nutritional status and morbidity were the outcomes. Odds ratios and 95% confidence intervals were to evaluate the effect of baseline inflammatory markers on the clinical outcomes after three years of follow-up and p-values < 0.05 were considered significant. RESULTS: We evaluated 38 children/adolescents with cystic fibrosis: 55% female; median age (with interquartile range), 3.75 years (2.71-7.00). Children/adolescents with high C-reactive protein/albumin ratio at baseline had odds of 18 (P = 0.018) of presenting forced expiratory volume in the first second ≤ 70% after three years. The other inflammatory markers were not associated with the outcomes. CONCLUSION: C-reactive protein/albumin ratio was associated with forced expiratory volume in the first second ≤ 70% after three years.

RESUMO

BACKGROUND/OBJECTIVES: Cystic fibrosis (CF) is characterized by excessive activation of immune processes. The aim of this study was to evaluate the effect of synbiotic supplementation on the inflammatory response in children/adolescents with CF. SUBJECTS/METHODS: A randomized, placebo-controlled, double-blind, clinical-trial was conducted with control group (CG, n = 17), placebo-CF-group (PCFG, n = 19), synbiotic CF-group (SCFG, n = 22), PCFG negative (n = 8) and positive (n = 11) bacteriology, and SCFG negative (n = 12) and positive (n = 10) bacteriology. Markers of lung function (FEV1), nutritional status [body mass index-for age (BMI/A), height-for-age (H/A), weight-for-age (W/A), upper-arm fat area (UFA), upper-arm muscle area (UMA), body fat (%BF)], and inflammation [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), IL-10, IL-6, IL-1ß, IL-8, myeloperoxidase (MPO), nitric oxide metabolites (NOx)] were evaluated before and after 90-day of supplementation with a synbiotic. RESULTS: No significance difference was found between the baseline and end evaluations of FEV1 and nutricional status markers. A significant interaction (time vs. group) was found for IL-12 (p = 0.010) and myeloperoxidase (p = 0.036) between PCFG and SCFG, however, the difference was not maintained after assessing the groups individually. NOx diminished significantly after supplementation in the SCFG (p = 0.030). In the SCFG with positive bacteriology, reductions were found in IL-6 (p = 0.033) and IL-8 (p = 0.009) after supplementation. CONCLUSIONS: Synbiotic supplementation shown promise at diminishing the pro-inflammatory markers IL-6, IL-8 in the SCFG with positive bacteriology and NOx in the SCFG in children/adolescents with CF.

RESUMO

PURPOSE: To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. METHODS: A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. RESULTS: Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. CONCLUSIONS: When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

RESUMO

BACKGROUND: (1) To compare nutrition and hydration status between a group of children/adolescents with cystic fibrosis (CFG; n = 46; median age, 8.5 years) and a control group without cystic fibrosis (CG). (2) To examine the association of nutrition and hydration status with lung function in the CFG. MATERIAL AND METHODS: A cross-sectional study. Nutrition screening, anthropometric parameters, and bioelectrical impedance analysis (BIA) were assessed. The z scores for body mass index for age, height for age, mid upper arm circumference, triceps and subscapular skinfold thickness, mid upper arm muscle area, resistance/height, and reactance/height were calculated. Bioelectrical impedance vector analysis was conducted. Forced expiratory volume in 1 second <80% was considered lung function impairment. An adjusted logistic regression was applied (P < .05). RESULTS: In the CFG, lung function impairment was observed in 51.1%. All anthropometric parameters were lower, and the mean z-resistance/height and z-reactance/height were higher in the CFG (P < .05) compared with the CG. In the CFG, 43% were severely/mildly dehydrated, while none were in the CG (P = .007). In the CFG, there was an association between high nutrition risk-via nutrition screening (odds ratio [OR], 22.28; P < .05), lower values of anthropometric parameters, higher z-resistance/height (OR, 2.23; P < .05) and z-reactance/height (OR, 1.81; P < .05), and dehydration (OR, 4.94; P < .05)-and lung function impairment. CONCLUSIONS: The CFG exhibited a compromised nutrition status assessed by anthropometric and BIA parameters. Nutrition screening, anthropometric and BIA parameters, and hydration status were associated with lung function.

RESUMO

This study examined the effect of an antioxidant intervention in biomarkers of inflammation and oxidative stress (OS) in the blood of Down syndrome (DS) children and teenagers during four different stages. A control group was composed by healthy children (n=18), assessed once, and a Down group composed by DS patients (n=21) assessed at the basal period (t0), as well as after 6 months of antioxidant supplementation (t1), after 12 months (after interruption of the antioxidant intervention for 6 months) (t2), and again after further 6 months of antioxidant supplementation (t3). Biomarkers of inflammation (myeloperoxidase activity - MPO and levels of IL-1ß and TNF-α) and OS (thiobarbituric acid reactive substances - TBARS, protein carbonyls - PC), reduced glutathione (GSH), uric acid (UA) and vitamin E levels, as well as antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST) and gamma-glutamyltransferase (GGT) activities, were measured after each period. After the antioxidant supplementation, the activities of SOD, CAT, GPx, GR, GGT and MPO were downregulated, while TBARS contents were strongly decreased, the contents of GSH and vitamin E were significantly increased, and no changes in G6PD and GST activity as well as in UA and PC levels were detected. After the interruption of the antioxidant therapy for 6 months, DS patients showed elevated GPx and GGT activities and also elevated UA and TBARS levels. No changes in SOD, CAT, GR, GST, G6PD and MPO activities as well as in GSH, vitamin E, PC, TNF-α and IL-1ß levels were detected. The results showed that the antioxidant intervention persistently attenuated the systemic oxidative damage in DS patients even after a relatively long period of cessation of the antioxidant intervention.

RESUMO

OBJECTIVE: To identify healthy food (HF) purchase habits and intake of fruits and vegetables (FV) in parents responsible for grocery shopping for their families. METHODS: Survey with mothers and fathers (n = 216) of children aged 7-10 years in Brazil. RESULTS: Grocery purchases occurred mostly at supermarkets. Purchase of HF was considered to be frequent by 80% of parents, who cited FV as main examples of HF. The more frequent the reported purchase was of HF, the higher was the prevalence of regular consumption of FV (P = .002). Only 34% of respondents reported weekly intakes that could be classified as regular. CONCLUSIONS AND IMPLICATIONS: Perceived frequent shopping for healthy foods was positively associated with regular consumption of FV but a gap between perception and behavior was identified. Nutrition education strategies need to go beyond a merely informative role and take consumers' opinions and points of view into consideration to become truly effective.

RESUMO

AIMS: Recurrent infections and activation of the inflammatory response affect the prognosis of cystic fibrosis (CF). We investigated the relationship between inflammatory response, infection, and pulmonary function in CF. MAIN METHODS: A clinical-cross-sectional study was conducted with 86 subjects: control group (CG, n=31, the same age and sex of the CF group), and CF group (CFG, n=55, age: 1-16 years), further distributed into CFG negative or positive bacteriology (CFGB(-)/CFGB(+)), and CFG negative or positive Pseudomonas aeruginosa (CFGPa(-)/CFGPa(+)). Using the Wald test, multiple linear regression (95% confidence interval) was performed between CG and CFG, and between CG and each of the CF subgroups (CFGB(-)/CFGB(+) and CFGPa(-)/CFGPa(+)). The inflammatory markers evaluated were myeloperoxidase (MPO), adenosine deaminase (ADA) activities, interleukin-1beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), nitric oxide metabolites (NOx) levels, and total and differential leukocyte counts. KEY FINDINGS: After adjusting for sex and age, CFG compared to CG revealed an increase of MPO, IL-1ß (P<0.001 in all subgroups), and CRP: CFG (P=0.002), CFGB(-) (P=0.007), CFGB(+) (P=0.009), CFGPa(-) (P=0.004) and CFGPa(+) (P=0.020). NOx (P=0.001, P<0.001), leukocytes (P=0.002, P=0.001), and neutrophils (P=0.003, P<0.001) were increased in CFGB(+) and CFGPa(+), respectively. A negative correlation between FEV1 and leukocytes (P=0.008) and FEV1 and neutrophils (P=0.031) resulted in CFG. SIGNIFICANCE: The inflammatory response characterized by the increase of MPO, IL-1ß, and CRP is determinant for CF. Also leukocytosis due to neutrophilia determines the pulmonary function deficiency in this disease.

RESUMO

Obesity is considered to be a chronic disease associated with early medical complications including: respiratory, cardiovascular, metabolic,psychological and social changes. Over recent decades, there has been a marked increase in the incidence of obesity among the population.Obesity has significant metabolic and systemic immune and inflammatory effects. Bariatric surgery has emerged as a treatment for morbid obesity. Oral changes following bariatric surgery were determined. One man and one woman, with initial Body Mass Indexes of 53-34 and 42-26 kg/m2 respectively, were followed for two years after undergoing Fobi Capella surgery. Dietary complications (frequent vomiting), nutrient deficiencies (iron, vitamin B12, calcium, folic acid and zinc) and xerostomia, sensitivity, and periodontitis were seen in both cases. Demineralization and infiltration of fillings evolved into erosion and an endodontic lesion (case 1) and mobility with consequent tooth loss (case 2). Problems with gingival bleeding, dental caries and dental mobility are directly related to compromising the absorptive area and/or the dietary behaviour of the individual after carrying out bariatric surgery.


A obesidade é considerada uma doença crônica associada a complicações médicas precoces como: alterações respiratórias, cardiovasculares, metabólicas, psíquicas e sociais. Nas últimas décadas, a obesidade tem apresentado um aumento considerável da sua incidência na população. A obesidade apresenta efeitos metabólicos e imunológicos e inflamatórios sistêmicos significativos. A cirurgia bariátrica tem sido visto como um tratamento para obesidade mórbida. Alterações bucais após cirurgia bariátrica foram avaliados. Um homem e uma mulher, com Índices de Massa Corporal iniciais de 53-34 e 42-26 kg/m2, respectivamente, foram acompanhados por dois anos após ser submetidos à cirurgia Fobi Capella. Seqüelas alimentares (vômito freqüente), deficiências de nutrientes (ferro, vitamina B12, cálcio, ácido fólico e zinco) e xerostomia, sensibilidade, e periodontite foram observados em ambos os casos. Desmineralização e infiltração de restaurações evoluíram para erosão e uma lesão endodôntico (caso 1), e mobilidade com conseqüente perda de dentes (caso 2). Problemas com sangramento gengival, cárie e mobilidade dentária são relacionados diretamente a uma diminuição na área para absorção e/ou o comportamento alimentar do indivíduo após cirurgia bariátrica.

RESUMO

UNLABELLED: Oral health is a prerequisite for a good chewing function, which may have an impact on food choices and nutritional well-being. OBJECTIVE: This study was designed to evaluate the relationship between oral health status and nutritional status in the elderly. MATERIAL AND METHODS: In this cross-sectional study, 33 elderly people from the Group for the Elderly Interdisciplinary Geriatrics and Gerontology Program, at Fluminense Federal University, Niteroi, RJ, Brazil, completed a questionnaire to collect information on socioeconomic status, eating habits, physical activity and health habits, undertook a clinical oral examination, blood test, and anthropometric measurements, and were allocated into groups according to age. The oral health status was assessed using the index for decayed, missing and filled teeth (DMFT). The nutritional status was assessed using hemoglobin, hematocrit and albumin concentrations in blood, anthropometric values and the body mass index. RESULTS: Tooth loss was the biggest nuisance to the elderly subjects (57.6%), followed by the use of dentures (30.3%) and ill-fitting dentures (33.3%). 66.6% of patients had difficulty in chewing, and 54.5% reported this to be due to prostheses and 13.6% to the absence of teeth. A significant correlation was found between DMFT and the value of suprailiac skinfold thickness (rho=0.380, p=0.029). CONCLUSION: The results support the temporal association between tooth loss and detrimental changes in anthropometry, which could contribute to increased risk of developing chronic diseases.

RESUMO

BACKGROUND: Bariatric surgery influences the intake and absorption of nutrients, which, when associated with vomiting, can damage the oral cavity. The serum concentrations of vitamin C and myeloperoxidase (MPO) and oral clinical manifestations were examined in patients 2 years after Roux-en-Y gastric bypass (RYGB). METHODS: Clinical prospective study with control group (CG; n = 26), assessed only once, and the bariatric group (BG; n = 26), assessed in the basal period and at 12 and 24 months after surgery. The mean ages in the CG and BG were 37.8 ± 1.51 and 39.6 ± 1.93 years, respectively, and their body mass indices were 22.07 ± 0.29 and 45.62 ± 1.46 kg/m(2), respectively. RESULTS: At 12 months after surgery, increased episodes of vomiting (P < .001) and dental hypersensitivity (P = .012) were observed, with a reduction in the saliva-buffering capacity of 21.3% ± 2.9% (P = .004). At 24 months after RYGB, a significant reduction in serum vitamin C was detected (32.9% ± 5.3%, P < .001), and MPO values were higher than in the basal period (P = .032). With regard to oral hygiene habits, 92.3% of patients reported frequent tooth brushing and 96.1% used fluoride, which were similar across the 2 years. However, dental hypersensitivity (P = .048) was significantly increased than baseline. CONCLUSIONS: The results demonstrated that vitamin C deficiency and increased vomiting after gastric bypass for morbid obesity may contribute to increased periodontal disease. The fact that it is impossible to determine which factor or factors (diet, poor compliance with supplementation, vomiting, poor oral hygiene) contributed to the dental problems in these patients is a shortcoming of the report.

RESUMO

BACKGROUND: The success of clinical dietary interventions depends on the motivation and willingness of study participants to adhere to the prescribed or provided diet. The aim of this study was to assess participants' adherence to their provided diet over the 6-month duration of the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE). METHODS: Investigators assessed the dietary adherence of 46 men and women who completed the first phase of the CALERIE trial. Volunteers were randomized to 1 of 4 dietary intervention groups: control, calorie restriction, calorie restriction with exercise, and low-calorie diet. Participants were provided with foods during 2 weeks of baseline and during the first 12 weeks and the last 2 weeks of the intervention as outpatients, and they completed a daily self-report form to assess diet adherence. The data are expressed as mean ± standard deviation or standard error of the mean. Pearson's correlation coefficient was determined to examine the relationship between assigned energy levels and total energy intake. RESULTS: Deviations reported were for eating nonstudy foods as well as not eating study foods. There were few deviations, and when converted to mean calories per day these did not affect total energy (weeks -3 to 2 = 10.25 ± 4.82, weeks 1-4 = 9.93 ± 12.52, weeks 5-11 = 8.38 ± 7.42, weeks 22-23 = 0.53 ± 3.97 kcal/d). The associations between assigned energy level and actual intake were high for all groups (P = .001), weeks -3 to -2 (r = 0.999), weeks 1-4 (r = 0.998), weeks 5-11 (r = 0.999), and weeks 22-23 (r = 0.998). CONCLUSIONS: The data provide evidence that dietary adherence is good when all foods are provided and when participants are highly motivated.

RESUMO

BACKGROUND: This study examined the effect of weight loss on energy intake, vitamin C, E, beta-carotene (diet/blood), reduced glutathione (GSH), C-reactive protein (CRP), thiobarbituric acid reactive substances (TBARS), catalase, and myeloperoxidase, in patients with Roux-en-Y bypass gastroplasty. METHODS: Prospective clinical study with control (C) and bariatric (B) groups (n = 20 each). Age was 38.8 +/- 11.1 (C) and 37.8 +/- 11.2 years (B), and body mass indices (BMI) were 22.4 +/- 2.4 and 48.1 +/- 8.7 kg/m(2), respectively. Group C was assessed on a single occasion and B at three time points (basal period and 3 and 6 months after gastroplasty). RESULTS: BMI was decreased at three (38.3 +/- 1.7, P = 0.018) and 6 months after surgery (34.9 +/- 1.7, P < 0.001). Mean weight loss was 20.53 +/- 1.1 after three and 27.96 +/- 1.3 kg after 6 months. Serum vitamin C and beta-carotene (P < 0.01 and P < 0.001, respectively) were increased at 6 months compared to basal. Basal serum vitamin C (P = 0.001) and beta-carotene (P < 0.001) were lower compared to controls. Serum vitamin E corrected for cholesterol and triglycerides was higher in group B at three (P = 0.01) and 6 months (P = 0.001) and lower at basal (P < 0.001) compared to controls. GSH was higher in controls (P < 0.001) compared to basal. Catalase (P = 0.01) and TBARS (P < 0.001) were higher in group B at 6 months. TBARS were higher (P < 0.001) at basal compared to controls. Myeloperoxidase and CRP decreased in group B after three (P = 0.028, P = 0.010) and 6 months (P < 0.001, P = 0.001), respectively. CONCLUSIONS: Roux-en-Y bypass gastroplasty led to decreased proinflammatory parameters together with increased nutritional antioxidants, catalase, and TBARS, and decreased GSH 6 months after surgery.
