Short-term nutritional counseling reduces body mass index, waist circumference, triceps skinfold and triglycerides in women with metabolic syndrome

Background: It is recognized that the growing epidemic of metabolic syndrome is related to dietary and lifestyle changes. Objective: The purpose of this study was to evaluate short-term application of nutritional counseling in women with metabolic syndrome. Methods: This follow-up study was conducted from September to November 2008 with thirty three women >= 35 years old screened clinically for nutritional counseling. Dietary intake was reported, and biochemical and body composition measures were taken at baseline and after three months of follow-up. Results: Of the 33 women evaluated, 29 patients completed the study. The prevalence of type 2 diabetes mellitus, hypertension, dyslipidemia, and obesity was high at 38%, 72.4%, 55.2%, and 75.8%, respectively. At the end of three-months of follow-up, a significant decline in body mass index, waist circumference, triceps skinfold, and triglycerides was observed, as was an increase in calcium and vitamin D intake. The multiple regression analysis showed that changes in body mass index, triceps skinfold, waist circumference and triglyceride levels after nutritional intervention were positively associated with changes in anthropometric (loss of body weight) and biochemical (decrease of TG/HDL-c ratio) parameters. Moreover, waist circumference changes were negatively associated with changes in calcium and vitamin D intake. Conclusion: Short-term nutritional counseling improved some factors of metabolic syndrome. Moreover, the increases in calcium and vitamin D consumption can be associated with the improvement in markers of metabolic syndrome.

Impact of nutritional counseling in reducing serum cholesterol in public health service patients

OBJECTIVE: To assess the impact of nutritional attention on the lipid profile and nutritional status of hypercholesterolemic patients attended in health centers of Belo Horizonte. METHODS: Using nutritional attendance patient record cards from two health units, the evolution of the lipid profile and the nutritional state (BMI) was monitored of 96 hypercholesterolemic patients who received diet. The patients were appraised at the following moments: initial (1st consultation), after 3 months (2nd consultation) and last consultation (variable for each patient). RESULTS: On the first attendance, 44,4% of the patients presented not only high total cholesterol and LDL-c, but also hypertriglyceridemia and 70.3% were overweight or obese, but most patients (75.6%) presented adequate HDL-c levels. There was significant reduction in the BMI, total cholesterol, LDL-c values (p < 0.01) and also in the triglyceride levels (p < 0.05) in the first three months, without alteration in the HDL-c levels. A significant reduction (p < 0.01) was observed in the frequency of individuals with high cholesterol (from 89.6% down to 47.9%), high and very high LDL-c (from 82.6% down to 45.7%), as well as high and very high triglyceride (from 43.6% down to 16.7%). The observed reduction in frequency of the low HDL-c was statistically meaningless. CONCLUSION: This study evidences the effect of the nutritional attention on lipid profile in hypercholesterolemic patients, reinforcing the need for a multiprofessional team to attend them at the public health services.

Impact of a nutritional counseling program on prevention of HAART-related metabolic and morphologic abnormalities

The advent of highly active antiretroviral therapy (HAART) improved HIV infection prognosis. However, adverse metabolic and morphologic effects emerged, highlighting a lack of investigation into the role of nutritional interventions among this population. The present study evaluated the impact of a nutritional counseling program on prevention of morphologic and metabolic changes in patients living with HIV/AIDS receiving HAART. A 12-month randomized clinical trial was conducted with 53 adults of both genders in use of HAART. Subjects were allocated to either an intervention group (IG) or a control group (CG). Nutritional counseling was based on the promotion of a healthy diet pattern. Anthropometrical, biochemical, blood pressure, and food intake variables were assessed on four separate occasions. Sub scapular skin-fold results showed a significant tendency for increase between time 1 (Mean IG = 14.9 mm; CG = 13.6 mm), time 3 (Mean IG = 16.7 mm; CG = 18.2 mm), and time 4 (Mean IG = 16.4 mm; CG = 17.7 mm). Lipid percentage intake presented a greater increase among controls (time 1 mean = 26.3%, time 4 mean = 29.6%) than among IG subjects (time 1 mean = 29.1%, time 4 mean = 28.9%). Moreover, participants allocated to the IG presented an increase in dietetic fiber intake of almost 10 grams. The proposed nutritional counseling program proved to be effective in improving diet by reducing fat consumption and increasing fiber intake.

Influence of clinical therapy and nutritional counseling on the recurrence of urolithiasis

PURPOSE: To evaluate the influence of combined clinical therapy and nutritional guidance on the recurrence of urolithiasis. METHODS: From our registry of patients with recurrent urolithiasis we selected 57 who had at least 5-years of follow-up. We collected 24h urine samples in order to analyze Ca, Na, uric acid, citrate, oxalate, and Mg concentrations and to assess urine volume. Patients filled out a clinical questionnaire before treatment, and abdominal radiographs and/or ultrasound were performed both before treatment and during the follow-up period. During follow-up, specific and individualized dietary advice was given based on the individual's metabolic disorders. Patients also received specific pharmacological treatment for their metabolic alterations. Outcome measures were metabolites in urine and the urolith recurrence rate. Pre- and post- intervention values were compared using tests as appropriate. RESULTS: Fifty six of the patients were male and the majority of patients were overweight. The mean BMI was 27 kg/m2. Urinary excretion of calcium, uric acid and sodium decreased significantly over the five year follow-up period. The number of uroliths that formed during the 5-year follow-up also decreased significantly compared to pre-treatment values. CONCLUSION: Individualized dietary advice combined with pharmacological treatment significantly reduces long-term urolithiasis recurrence.

NUTRITIONAL COUNSELING OFFERED TO CHILDREN AND ADOLESCENTS WITH DISABILITIES

Objective: To evaluate the nutritional counseling offered to children and adolescents with disabilities in the municipality of Santa Cruz, RN, Brazil. Methods: Observational, crosssectional, population-based study, developed from May to December 2013, with 102 children and adolescents attending a Children’s Rehabilitation Center. We conducted socioeconomic, demographic, health and lifestyle assessments, and evaluated the received nutritional assistance (whether they had received nutritional counseling from any health professional in relation to food and nutrition, how often it occurred and which professional conducted such counseling). Results: Only 37% (n=37) of parents had received some nutritional guidance. Regarding the frequency of counseling, only 11.8% (n=4) of the youngsters received it 7 or more times/year; 23.5% (n=8) received it 2 to 6 times/year; and most (64.7 %, n=22) received it 1 time/year or less. The length of the nutritional counseling was short: the majority (64.7%, n=22) received only one guidance session throughout the whole period attending the institution, and less than 15% (n=5) received counseling for more than six consecutive months. For the majority (73.5%, n=25), the amount of time receiving nutritional guidance has not reached half of the monitoring period. Nutritional counseling was carried out mainly by nutritionists (89.2%, n=33). Conclusion: There was a low frequency of nutritional counseling directed specifically to the disabilities presented by the participants. When such activity was conducted, it occurred irregularly during the participant´s follow-up, only during a short period of time, and lacking connection with the monitoring by the multidisciplinary team.

A importância da intervenção nutricional na redução do peso corpóreo em pacientes com síndrome do anticorpo antifosfolípide

OBJETIVO: Avaliar a eficácia da intervenção nutricional na redução do excesso de peso (EP), em pacientes com síndrome do anticorpo antifosfolípide (SAF). MÉTODO: Incluídos 40 pacientes, acima de 18 anos, com diagnóstico de SAF primária ou secundária, acompanhados no Serviço de Reumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP) e recrutados no período de outubro de 2005 a fevereiro de 2006. Foram coletados dados demográficos e realizados a revisão de prontuários, a mensuração de peso e da altura, o cálculo do índice de massa corpórea (IMC) atual e a adequação da dieta pelo IMC ideal. Foi realizada avaliação na primeira consulta e após intervalo mínimo de dois meses. RESULTADOS: A média de idade dos pacientes foi de 41 anos, sendo 93% de mulheres. Os pacientes com SAF primária perfaziam 25%, com média de dois anos da doença. A trombose venosa ocorreu em 63%, arterial em 48% e manifestações obstétricas em 27%. Na primeira consulta, 68% apresentavam EP, 27% eram eutróficos e 5% estavam com baixo peso (BP). Após três meses de intervenção, os eutróficos mantiveram o peso e os de BP tornaram-se eutróficos, segundo o IMC. Interessantemente, entre os pacientes com EP (n = 27), 82% emagreceram, 14% engordaram e 4% se mantiveram. Especificamente, 11 pacientes apresentaram 1% a 3% de perda ponderal de peso, oito perderam de 4% a 7%, dois reduziram 8% a 9% e um reduziu 13,6% com o acompanhamento nutricional. CONCLUSÃO: Foi demonstrado no presente estudo que a intervenção nutricional conseguiu atingir metas para redução de peso, possibilitando diminuição no risco trombótico num curto período, sendo, portanto, uma modalidade terapêutica inicial e de eleição para corrigir o EP em pacientes com SAF.

Processus décisionnel de la femme enceinte immigrante : étude exploratoire chez des primigestes et secondigestes

Malgré le rôle important joué par les comportements alimentaires durant la grossesse, et de leurs implications pour la santé de la mère et de l’enfant à naître, plusieurs études soulignent que les besoins d’informations des femmes enceintes à faible revenu ou issues de minorités ethniques n’ont pas été comblés. Le comportement de recherche d’informations de femmes enceintes immigrantes maghrébines à faible revenu sera donc abordé via le modèle d’Engel, Kollat et Blackwell. L’objectif général est l’exploration de ce comportement de recherche d’informations en lien avec des thématiques associées à leur alimentation au cours de la grossesse. La thèse propose quatre questions spécifiques de recherche visant l’exploration des facteurs d’ordre individuel et d’environnement susceptibles d’influencer une recherche active d’informations, des sources auprès desquelles des informations sont recherchées, et de la nature de l’information recueillie. Un total de 28 femmes enceintes volontaires (14 primigestes et 14 secondigestes) ont été recrutées via le Dispensaire diététique de Montréal entre les mois d’août 2010 et 2011. Des entrevues semi-structurées de 60 à 90 minutes ont été réalisées par l’étudiante au doctorat. Les données ont été soumises à une analyse de contenu via le logiciel NVivo. Des facteurs d’ordre individuel susceptibles d’influencer le comportement de recherche active d’informations furent identifiés: perspective idéologique à l’égard de la grossesse, présence de malaises de grossesse, perception du caractère contradictoire des informations reçues, perceptions liées au caractère adéquat de l’information reçue, perceptions liées au caractère suffisant de l’information détenue, variation du poids corporel, valorisation du bien-être du bébé, attitudes à l’égard de la supplémentation prénatale, valorisation d’une saine alimentation et motivation à apprendre. Des facteurs d’environnement susceptibles d’influencer le comportement de recherche active d’informations ont été identifiés: culture (habitudes alimentaires, croyances alimentaires, croyances religieuses, perte de repères culturels traditionnels quant aux soins de santé et conseils offerts durant la grossesse) et interactions avec les membres de l’environnement social. Des sources d’informations significatives en lien avec la nutrition prénatale se sont avérées être pour les primigestes: diététiste, mère, amies, mari et Internet. Pour les secondigestes, ces sources d’informations étaient: diététiste, médecin, amies et mari. Une source d’informations professionnelle significative concernant la supplémentation prénatale et le gain de poids durant la grossesse, tant pour les primigestes que secondigestes, s’est révélée être la diététiste. Peu de femmes ont rapporté avoir reçu des professionnels de l’information à propos de la salubrité alimentaire et des risques de gagner trop de poids. Les résultats soulèvent une réflexion à l’égard de l’implication des professionnels en période prénatale et quant à la révision de leurs approches de counseling nutritionnel. Les résultats amènent également à réfléchir quant à l’amélioration des activités ayant pour objectif de répondre aux besoins d’informations des femmes enceintes immigrantes maghrébines à faible revenu en lien avec des thématiques liées à l’alimentation durant la grossesse. Pour terminer, il serait utile que de futures recherches s’attardent à mieux comprendre le comportement de recherche d’informations en lien avec des thématiques associées à l’alimentation de femmes enceintes de différents horizons culturels ou de celle de l’enfant à venir.

High intake of fruits and vegetables predicts weight loss in Brazilian overweight adults

To determine whether changes in dietary intakes predict weight loss, we studied 80 overweight adults who attended a nutritional counseling program during 6 months of follow-up at a primary health care center in Brazil. Habitual diet was assessed using a validated food frequency questionnaire at baseline and after 6 months. The mean age (+/-SD) of the participants was 46.5 +/- 9.5 years, and their mean body mass index was 29 +/- 3 kg/m(2) at baseline. After 6 months, the differences in body weight and fruit/vegetable intake were -1.4 +/- 3 kg and 109 +/- 320 g daily, respectively. Using multiple linear regression models adjusted for age, sex, changes in walking time, and total energy intake, the increased intake of dietary fiber from fruits/vegetables was associated with a greater weight loss (beta 1 [95% confidence interval (CI)] = -0.180 [-0.269, -0.0911) after 6 months of follow-up. Similar results were observed for increased intake of vegetables (beta 1 [95% CI] = -0.00497 [-0.008, -0.0021) and fruits (beta 1 [95% CI] = -0.00290 [-0.005, -0.001]) as predictors of weight loss. The increase of 100 g/d of vegetables and fruits represented a body weight loss of 500 and 300 g after 6 months, respectively (P <.05). Our findings support the relevance of increased intakes of fruits and vegetables that may help avoid weight gain in overweight adults. (C) 2008 Elsevier Inc. All rights reserved.

Association between hypervolemia and ventricular hypertrophy in hemodialysis patients

Background: Left ventricular hypertrophy (LVH) is a well-known predictor of cardiovascular mortality in patients who have end-stage renal disease and are maintained on hemodialysis (HD), and LVH is not always correlated with the severity of hypertension in these patients. The purpose of this study was to investigate the role of other factors contributing to LVH.Methods: A total of 50 patients with HD were classified in three groups according to whether their LV mass index (LVMI) was higher than (n = 15), equal to (n = 20), or lower than (n = 15) that predicted by a formula based on their ambulatory blood pressure monitoring (ABPM).Results: Subjects with higher LVMI than predicted had significantly greater inter-HD weight gain (3.4 +/- 0.8 v 2.7 +/- 0.8 and 2.6 +/- 05 kg, respectively, in the other two groups, P < .05), and subjects with lower LVMI than predicted had a tendency toward a more pronounced nocturnal dipping pattern of BP (P = .07 v the other two groups), although daytime and night-time average BP levels did not differ between groups. All other clinical and laboratory parameters were similar among the three groups except higher cardiac output and various indices of LVH, which were more pronounced in the group with higher LVMI by ABPM. This group had also the lowest survival rate over the 2 to 3 years of follow-up, with five deaths versus two in each of the other two groups.Conclusions: the data suggest that correct management of inter-HD weight gain by nutritional counseling and shorter inter-HD intervals may prevent LVH and improve survival independently of BP control.
