RESUMEN

This cross-sectional study employs Structural Equation Modelling (SEM) to explore both direct and indirect effects of parental level of education and child individual factors on the length-for-age outcomes in children aged 6-24 months assisted by the Bolsa Família Program in the State of Alagoas. A total of 1,448 children were analyzed by the SEM technique. A negative standardize direct effect (SED) of the children's younger age (SED: -0.06; p=0.017), the use of bottle feeding (SED: -0.11; p<0.001), and lack a minimum acceptable diet (SED: -0.09; p<0.001) on the length-for-age indicator was found. Being female (SDE: 0.08; p=0.001), the higher birth weight (SDE: 0.33; p<0.001), being ever breastfed (SED: 0.07; p=0.004) and a higher level of parental education (SDE: 0.09; p<0.001) showed a positive SDE effect on the child's length-for-age. The model also demonstrated a negative standardize indirect effect (SIE) of the sweet beverage consumption (SIE: -0.08; p=0.003) and a positive effect of being ever breastfed (SIE: 0.06; p=0.017) on the child's length-for-age through parental level of education as a mediator. This research underscores the crucial role of proper feeding practices and provide valuable insights for the development of targeted interventions, policies, and programs to improve the nutritional well-being and promote adequate linear growth and development among young children facing similar challenges.

RESUMEN

This study aimed to assess the association between the double burden of malnutrition (DBM) with continued breastfeeding and the early introduction of ultra-processed drinks in children living in situations of social vulnerability. This cross-sectional population-based study was carried out in a capital city in the Northeast of Brazil, which included 561 children. It was observed that introducing soft drinks into the child's diet during the first year of life was directly associated with DBM but indirectly with continuous breastfeeding for 12 or more months. These results indicate paths that can be followed to reverse the current scenario.

RESUMEN

Breastfeeding is the first guarantee of the human right to adequate food and the benefits of continued breastfeeding up to 2 years of age are well established. This cross-sectional study sought to explore the association between socioeconomic, demographic, and nutritional factors and the practice of continued breastfeeding in children aged 6 to 24 months assisted by the Brazilian conditional cash transfer program, Bolsa Família. Our findings emphasize the role of unfavorable socioeconomic conditions in diminishing the practice of continued breastfeeding. They also suggest the importance of policy-level actions to promote and support breastfeeding and to combat early ultra-processed foods consumption.

RESUMEN

OBJECTIVE: Alcohol-related liver disease (ALD) ranges from never-decompensated ALD (ndALD) to the life-threatening decompensated phenotype, known as alcohol-related hepatitis (AH). A multidimensional study of the clinical, histological and molecular features of these subtypes is lacking. DESIGN: Two large cohorts of patients were recruited in an international, observational multicentre study: a retrospective cohort of patients with ndALD (n=110) and a prospective cohort of patients with AH (n=225). Clinical, analytical, immunohistochemistry and hepatic RNA microarray analysis of both disease phenotypes were performed. RESULTS: Age and mean alcohol intake were similar in both groups. AH patients had greater aspartate amino transferase/alanine amino transferase ratio and lower gamma-glutamyl transferase levels than in ndALD patients. Patients with AH demonstrated profound liver failure and increased mortality. One-year mortality was 10% in ndALD and 50% in AH. Histologically, steatosis grade, ballooning and pericellular fibrosis were similar in both groups, while advanced fibrosis, Mallory-Denk bodies, bilirubinostasis, severe neutrophil infiltration and ductular reaction were more frequent among AH patients. Transcriptome analysis revealed a profound gene dysregulation within both phenotypes when compare to controls. While ndALD was characterised by deregulated expression of genes involved in matrisome and immune response, the development of AH resulted in a marked deregulation of genes involved in hepatocyte reprogramming and bile acid metabolism. CONCLUSIONS: Despite comparable alcohol intake, AH patients presented with worse liver function compared with ndALD patients. Bilirubinostasis, severe fibrosis and ductular reaction were prominent features of AH. AH patients exhibited a more profound deregulation of gene expression compared with ndALD patients.

RESUMEN

OBJECTIVE: This study aimed to describe how strong is the relationship between TEE and PAL in women living in an impoverished Brazilian urban area. METHODS: Anthropometric, hormonal (insulin, TSH, FT4 , and FT3 ), body composition (deuterium), TEE (doubly labeled water) and PAL (metabolic equivalent task [MET]-7-day triaxial accelerometer, ActivPAL®) data were collected from 55 women (mean age: 31y, mean BMI: 27.4 kg/m2 ). Adjusted-TEE models were calculated incorporating the residuals of anthropometric, hormonal, and body composition variables in the TEE, to assess the relation between MET and adjusted-TEE, through three different analyzes: linear regression, nonlinear regression and change-point regression. RESULTS: Most participants (89.1%, n = 49) were classified as low-active. There was no association between crude TEE and MET.h/d (R2  = 0.05; p = 0.09). There was a positive, although weak, linear relationship between adjusted-TEE and MET.h/d (ß = 2705.26 kcal; 95% CI: 436.25; 4974.27; adj-R2  = 0.08). A change point of this relationship was identified in the MET.h/d value of 1.53 (SD = 0.02; adj-R2 = 0.13). The association between adjusted-TEE and MET.h/d before the change point (ß = 5101.46 kcal; 95%CI: 978.84; 9224.08; adj-R2  = 0.11) was stronger than the association in the full linear model, nevertheless, it was still weak. This association stop existing when it is assessed in individuals after the change point (ß = -6609.92 kcal; 95%CI: -16773.24; 3553.40; adj-R2  = 0.08). CONCLUSIONS: These results suggest that the relationship between TEE and PAL is weak and it is not completely linear in women living in an impoverished Brazilian urban area.

RESUMEN

The increased risk of cardiovascular disease (CVD) conferred by hepatitis C virus (HCV) is especially relevant after liver transplantation (LT), but its mechanism is still not well defined. This study aimed to evaluate the influence of HCV eradication in inflammatory and endothelial activation markers after LT. We evaluated inflammatory (TNF-alfa, IL-6, IL-8, and MCP-1) and endothelial activation (E-selectin, ICAM-1, VCAM-1, and MMP-9) markers before and after eradication in 45 LT recipients with HCV infection (LT+/HCV+) and 44 non-transplanted HCV-infected patients (LT-/HCV+). We also considered an additional group of 40 LT recipients without HCV infection (LT+/HCV-). LT+/HCV+ patients presented a higher endothelial activation status before eradication compared with LT+/HCV- patients. However, levels of E-selectin, ICAM-1, VCAM-1, and MMP-9 were comparable between LT+/HCV+ and LT-/HCV+ patients before eradication. HCV eradication decreased ICAM-1 (5466.55 pg/ml vs. 3354.88 pg/ml, P < 0.001) and VCAM-1 (10456.52 pg/ml vs. 6658.85 pg/ml, P < 0.001) levels in LT+/HCV+ and LT-/HCV+ patients. Remarkably, HCV eradication restored levels of endothelial activation markers of LT+/HCV+ patients compared with that of LT+/HCV- patients. HCV plays a major role in endothelial dysfunction after LT. Furthermore, HCV eradication restores endothelial activation despite the exposure to immunosuppressive therapy.

RESUMEN

Evaluative judgment-i.e., assessing to what degree a stimulus is liked or disliked-is a fundamental aspect of cognition, facilitating comparison and choosing among alternatives, deciding, and prioritizing actions. Neuroimaging studies have shown that evaluative judgment involves the projection of sensory information to the reward circuit. To investigate whether evaluative judgments are based on modality-specific or modality-general attributes, we compared the extent to which balance, contour, symmetry, and complexity affect liking responses in the auditory and visual modalities. We found no significant correlation for any of the four attributes across sensory modalities, except for contour. This suggests that evaluative judgments primarily rely on modality-specific sensory representations elaborated in the brain's sensory cortices and relayed to the reward circuit, rather than abstract modality-general representations. The individual traits art experience, openness to experience, and desire for aesthetics were associated with the extent to which design or compositional attributes influenced liking, but inconsistently across sensory modalities and attributes, also suggesting modality-specific influences.

RESUMEN

OBJECTIVE: This study aimed to verify the association between socio-economic and demographic characteristics and dietary patterns (DP) of children assisted by the Conditional Cash Transfer Program, Bolsa Família Program (BFP). DESIGN: This is a cross-sectional study. DP were defined using a principal component analysis. The association of the predictive variables and DP was modelled using multilevel linear regression analysis. SETTING: This study was conducted in six municipalities from the State of Alagoas, Brazil. PARTICIPANTS: The participants were children aged 6-24 months who were assisted by the BFP. RESULTS: A total of 1604 children were evaluated. Four DP were identified (DP1, DP2, DP3 and DP4). DP1 is composed of traditional Brazilian food. DP2 is formed mostly from ultra-processed foods (UPF). DP3 consists of milk (non-breast) with added sugar, while DP4 consists of fresh and minimally processed foods. Caregivers with higher age and education (ß = -0·008; (95 % CI -0·017, -0·000); ß = -0·037; (95 % CI -0·056, -0·018), respectively) were negatively associated with DP2. We observed a negative association between households with food insecurity (ß = -0·204; (95 % CI -0·331, -0·078)) and DP4 and a positive association between caregivers with higher age and education (ß = 0·011; (95 % CI (0·003; 0·019); ß = 0·043; (95 % CI 0·025, 0·061), respectively) and DP4. CONCLUSION: This study identified the association between socio-economic inequities and DP early in life, with an early introduction of UPF, in children assisted by BFP in the State of Alagoas.

RESUMEN

OBJECTIVE: To evaluate the association between the consumption of ultra-processed foods (UPF) and the practice of breast-feeding in children under 2 years of age assisted by the conditional cash transfer programme, Bolsa Família Programme (PBF). DESIGN: A cross-sectional study. The consumption of UPF and the practice of breast-feeding were assessed using a structured 24-h recall. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels. SETTING: Six counties from the state of Alagoas, Brazil. PARTICIPANTS: Children aged 6-24 months, assisted by PBF. RESULTS: A total of 1604 children were evaluated, 11·7% of whom were overweight, and most had consumed UPF (90·6%) in the last 24 h. The most consumed UPF were biscuits, chocolate milk and baby food with 74·8, 66·8 and 24·9%, respectively. Through multivariable analysis, an association was found between lower consumption of UPF in the continuation of breast-feeding until the second year of life (prevalence ratio (PR) 0·91, 95 % CI 0·86, 0·96) and in the first year of life (PR 0·93, 95 % CI 0·88, 0·99). CONCLUSIONS: It was found that the studied population had a high consumption of UPF, which harmed continued breast-feeding. We highlight the importance of strengthening public policies aimed at the promotion, protection and support of breast-feeding and healthy complementary feeding aimed at populations that have difficulties in physical and economic access to a healthy and adequate diet.

RESUMEN

OBJECTIVE: To evaluate the association between Fe deficiency anaemia (IDA) and complementary feeding in children under 2 years old assisted by the Conditional Cash Transfer programme, Bolsa Família (BFP). DESIGN: Cross-sectional study. Data were obtained through a standardised form, questionnaire to assess the eating habits of children under 2 years of age, capillary Hb (HemoCue®) and the Brazilian Household Food Insecurity Measurement Scale. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels. SETTING: Six municipalities from the State of Alagoas, Brazil. PARTICIPANTS: Children aged 6-24 months assisted by BFP. RESULTS: A total of 1604 children were evaluated, among whom 58·1 % had anaemia. A higher number of food groups consumed (prevalence ratio (PR) = 0·97; 95 % CI 0·95, 0·99; P = 0·009), the consumption of dairy (PR = 0·86; 95 % CI 0·79, 0·84; P = 0·001) and meat (PR = 0·90; 95 % CI 0·83, 0·99; P = 0·030) in addition to bottle feeding (PR = 0·88; 95 % CI 0·82, 0·96; P = 0·004) were associated with a lower prevalence of IDA. CONCLUSIONS: IDA is still a serious public health problem in children under 2 years old assisted by BFP in Alagoas. We highlight the importance of promoting complementary feeding based on a diversified dietary intake, as well strengthening prophylactic supplementation programmes to increase children's adherence in conjunction with the implementation of food and nutrition education to help reduce the prevalence of this condition.

RESUMEN

Mobile health (mHealth) has emerged as a potential solution to providing valuable ecological information about the severity and burden of Parkinson's disease (PD) symptoms in real-life conditions. Objective: The objective of our study was to explore the feasibility and usability of an mHealth system for continuous and objective real-life measures of patients' health and functional mobility, in unsupervised settings. Methods: Patients with a clinical diagnosis of PD, who were able to walk unassisted, and had an Android smartphone were included. Patients were asked to answer a daily survey, to perform three weekly active tests, and to perform a monthly in-person clinical assessment. Feasibility and usability were explored as primary and secondary outcomes. An exploratory analysis was performed to investigate the correlation between data from the mKinetikos app and clinical assessments. Results: Seventeen participants (85%) completed the study. Sixteen participants (94.1%) showed a medium-to-high level of compliance with the mKinetikos system. A 6-point drop in the total score of the Post-Study System Usability Questionnaire was observed. Conclusions: Our results support the feasibility of the mKinetikos system for continuous and objective real-life measures of a patient's health and functional mobility. The observed correlations of mKinetikos metrics with clinical data seem to suggest that this mHealth solution is a promising tool to support clinical decisions.

RESUMEN

BACKGROUND & AIMS: Fontan surgery is used to treat a variety of congenital heart malformations, and may lead to advanced chronic liver disease in the long-term. This study examines the prevalence, characteristics and predictors of liver nodules in patients following Fontan surgery. METHODS: This was a prospective, cross-sectional, observational study conducted at 8 European centres. Consecutive patients who had undergone Fontan surgery underwent blood tests, abdominal ultrasonography (US), transient elastography (Fibroscan®), echocardiography, haemodynamic assessments, and abdominal MRI/CT scan. The primary outcome measure was liver nodules detected in the MRI/CT scan. Predictors of liver nodules were identified by multivariate logistic regression. RESULTS: One hundred and fifty-two patients were enrolled (mean age 27.3 years). The mean time elapsed from surgery to inclusion was 18.3 years. Liver nodule prevalences were 29.6% (95% CI 23-37%) on US and 47.7% (95% CI 39-56%) on MRI/CT. Nodules were usually hyperechoic (76.5%), round-shaped (>80%), hyperenhancing in the arterial phase (92%) and located in the liver periphery (75%). The sensitivity and specificity of US were 50% (95% CI 38-62%) and 85.3% (95% CI 75-92%), respectively. Inter-imaging test agreement was low (adjusted kappa: 0.34). In the multivariate analysis, time since surgery >10 years was the single independent predictor of liver nodules (odds ratio 4.18; p = 0.040). Hepatocellular carcinoma was histologically diagnosed in 2 of the 8 patients with hypervascular liver nodules displaying washout. CONCLUSION: While liver nodules are frequent in Fontan patients, they may go unnoticed in US. Liver nodules are usually hyperechoic, hypervascular and predominantly peripheral. This population is at risk of hepatocellular carcinoma, the diagnosis of which requires confirmatory biopsy. LAY SUMMARY: Fontan surgery is the standard of care for many patients with univentricular congenital cardiopathies. Recent advances have improved the survival of Fontan patients, and nowadays most of them reach adulthood. In this setting, Fontan-associated liver disease (FALD) is increasingly recognised, and has become a significant prognostic factor. Liver nodules are considered a component of FALD yet their prevalence, imaging features and predictors have hardly been evaluated. In this study, we observed that liver nodules are frequent, typically hyperechoic, hypervascular and predominantly peripheral in patients with FALD. This population is at risk of hepatocellular carcinoma, the diagnosis of which must be confirmed by biopsy.

RESUMEN

PURPOSE: To determine the risk factors related to adnexal involvement in endometrial cancer (EC) and its implications for ovarian preservation in young women. METHODS: We analyzed a series of 802 patients who were treated at AC Camargo Cancer Center from July 1991 to July 2017. Patients who had peritoneal or systemic dissemination (stage IV) were excluded. Chi square and Fisher's exact tests were used to analyze the correlations between categories and clinicopathological variables. Multivariate analysis was performed by logistic regression. RESULTS: Forty-nine (6.2%) patients had adnexal involvement-43 (5.4%) ovarian and 24 (2.9%) tubal. After excluding the 14 (28%) cases with suspicious findings, 788 subjects were analyzed and adnexal involvement found in 35 (4.4%) cases. Adnexal involvement was statistically related to non-endometrioid histologies (12.6% vs. 3.1%; p < 0.001), lymph node metastasis (17% vs. 2.6%; p < 0.001), histological grade 3 tumors (9.4% vs. 2.1%; p < 0.001), presence of LVSI (14.2% vs. 2.4%; p < 0.001), and deep myometrial invasion (≥ 50%) (10.8% vs. 3.5%; p < 0.001). Although age younger than 45 years had higher risk of adnexal involvement, it was not statistically significant (8.9% vs. 4.2%; p = 0.13). Seven (14.2%) patients with adnexal involvement were aged < 45 years, 3 of whom (42.8%) had suspicious adnexal masses that were detected before surgery. Notably, all patients aged < 45 years and with adnexal involvement had at least 1 risk factor, such as presence of LVSI, grade 3 disease, node metastasis, or deep myometrial invasion. No patient with clinically normal ovaries and aged under 45 years, with endometrioid grades 1 and 2, superficial myometrial invasion, or node negativity had adnexal involvement. CONCLUSIONS: Ovarian preservation may be considered for patients younger than 45 years old with low-risk EC (grades 1 and 2 tumors, absence of LVSI, and myometrial invasion < 50%).

RESUMEN

OBJECTIVE: The present study aimed to determine whether physical activity and energy intake are associated with the anthropometric and blood cardiovascular risk factors alterations in women living in social vulnerability for a period of 2 years. METHODS: The study was carried out with women residing in the outskirts of Maceió-AL, aged between 19 and 45 years. We characterized the socioeconomic and biochemical profile (glucose, insulin, and blood lipids) at the beginning and at the end of the study. Anthropometric evaluation was performed in three moments: at the beginning, and after 1 and 2 years of follow-up. Energy expenditure, measured by doubly labeled water, physical activity, measured by 7-day triaxial accelerometry, and energy intake, measured by 3-day 24-hour food recall, were collected at baseline. RESULTS: After 2 years, 34 women were completely assessed, with a mean age of 33.7 years. Women spent around 16 hours of the day sitting/lying down. There was an increase in body weight (from 64.61 ± 11.69 to 66.37 ± 13.26 kg, P < .01), which was not associated with any of the predictors. There was also an increase in waist/hip ratio (WHR) (from 0.84 ± 0.07 to 0.87 ± 0.05, P < .01), which was positively associated with the amount of sitting/lying time per day. There were no significant alterations in blood cardiovascular risk factors. CONCLUSION: Energy intake did not predict anthropometrical changes. Sitting/lying time was associated with an increase in WHR, but not in body weight or blood cardiovascular risk factors in low-income women.

RESUMEN

OBJECTIVE: To evaluate the association between weight status and food insecurity of children living in social vulnerability who are beneficiaries of a food assistance programme (FAP). DESIGN: Cross-sectional study. SETTING: From all children benefiting from the FAP in the municipality, 30 % were mapped in forty-seven distribution points. Their weight status was evaluated using BMI-for-age and food insecurity was determined with the Brazilian Food Insecurity Scale. Socio-economic data of the participants were collected using regular questionnaires. The main outcome measure was obesity. PARTICIPANTS: To be a beneficiary of the FAP, a family must have a child aged 24-96 months and receive less than half a minimum wage per capita. Participating families receive 1 litre of whole milk per day. RESULTS: In all, 1487 children had BMI-for-age and food insecurity data. Of these children, 376 (25·3 %) had excess weight, of whom 164 (11·0 %) presented with obesity, and only twenty-seven (1·8 %) were underweight; 76 % of the families had some degree of food insecurity. Multivariable analysis revealed no overall association between household food insecurity and weight status. In the specific comparison, children living in severe food insecurity were less likely to present obesity than those children living in food security (prevalence ratio = 0·60; 95 % CI 0·38, 0·96; P = 0·03). CONCLUSIONS: In a socially vulnerable population that participates in a FAP, there was no overall association between food insecurity and weight status in children, a result which is similar to what is observed in more developed contexts.

RESUMEN

We present a novel set of 200 Western tonal musical stimuli (MUST) to be used in research on perception and appreciation of music. It consists of four subsets of 50 stimuli varying in balance, contour, symmetry, or complexity. All are 4 s long and designed to be musically appealing and experimentally controlled. We assessed them behaviorally and computationally. The behavioral assessment (Study 1) aimed to determine whether musically untrained participants could identify variations in each attribute. Forty-three participants rated the stimuli in each subset on the corresponding attribute. We found that inter-rater reliability was high and that the ratings mirrored the design features well. Participants' ratings also served to create an abridged set of 24 stimuli per subset. The computational assessment (Study 2) required the development of a specific battery of computational measures describing the structural properties of each stimulus. We distilled nonredundant composite measures for each attribute and examined whether they predicted participants' ratings. Our results show that the composite measures indeed predicted participants' ratings. Moreover, the composite complexity measure predicted complexity ratings as well as existing models of musical complexity. We conclude that the four subsets are suitable for use in studies that require presenting participants with short musical motifs varying in balance, contour, symmetry, or complexity, and that the stimuli and the computational measures are valuable resources for research in music psychology, empirical aesthetics, music information retrieval, and musicology. The MUST set and MATLAB toolbox codifying the computational measures are freely available at osf.io/bfxz7.

RESUMEN

The prevalence and management of coronary artery disease (CAD) in liver transplantation (LT) candidates are not well characterized. The aims of this study were to evaluate the impact on clinical outcomes of a specifically designed protocol for the management of asymptomatic CAD in LT candidates and to investigate noninvasive risk profiles for obstructive and nonobstructive CAD for 202 LT candidates. Those with high baseline cardiovascular risk (CVR; defined by the presence of classic CVR factors and/or decreased ejection fraction) received coronary angiography and significant arterial stenosis and were treated with percutaneous stents. Patients were followed up after LT until death or coronary event (CE). There were 78 patients who received coronary evaluation (62 direct angiography, 14 computed tomography coronary angiography, and 2 both). Of them, 39 (50%) patients had CAD of any severity, and 6 (7.7%) had significant lesions (5 were amenable to be treated with stents, whereas 1 patient had diffuse lesions which contraindicated the LT). Insulin-dependent diabetes was the only factor related to CAD of any severity (odds ratio, 3.44; 95% confidence interval [CI], 1.00-11.97). A total of 69 patients (46 with coronary evaluation) received LT. The incidence of CEs and overall survival after LT were similar between patients with and without coronary evaluation. Furthermore, no differences occurred between these groups in a multivariate competing risk model (subhazard ratio, 0.84; 95% CI, 0.27-2.61; P = 0.76). In conclusion, the application of an angiographic screening protocol of CAD in a selected high-risk Mediterranean population is safe and effective. The short- and medium-term incidence rates of CEs and death after LT in this population are similar to that observed in low-risk patients.

RESUMEN

An aptamer-amphiphile was designed that binds to ß-lactoglobulin (ß-LG), a major allergen from cow's milk. For this work, a 23-nucleotide ssDNA aptamer ß-LG-23, capable of forming antiparallel G-quadruplexes was used, and its specificity and binding affinity of 22 ± 2 nM for ß-LG were evaluated via enzyme-linked apta-sorbent assay (ELASA). The ß-LG-23 aptamer was synthesized as an amphiphile by conjugating it to a C16 double tail via different spacers, and the effect of the spacers on the binding affinity and secondary structure of the aptamer was investigated. From all amphiphiles tested, direct conjugation of the aptamer to the tail gave the lowest binding affinity to ß-LG (37 ± 2 nM), while maintaining the antiparallel G-quadruplex secondary structure of the aptamer. As a proof of concept, the ß-LG-23 aptamer-amphiphile was used to decorate the interface of a liquid crystal (LC) and effectively detected 10 nM or 0.18 ppm of ß-LG with a 20 min equilibration time, thus demonstrating that it has the potential to be used for fast and label-free detection of ß-LG.

RESUMEN

Low-income women are the group with the highest levels of obesity worldwide. In low-income settings, the use of predictive equations, which yield a measure of the individuals' BMR, is a feasible approach to estimate the individuals' total energy expenditure (TEE), using the factorial method (calculated-TEE = BMR × physical activity level), an important step of the obesity nutritional care. The present study aimed to identify the predictive equation that, in conjunction with metabolic equivalents of tasks (MET) data from accelerometers, yields the calculated-TEE with better agreement compared with the TEE measured by doubly labelled water (TEE-DLW). Forty-five women aged 19-45 years, with excess weight and mothers of undernourished children, were included. They received DLW to determine TEE (14 d); at the same time, they used triaxial accelerometers (7 d) to estimate their MET. The Bland-Altman method, paired-sample t tests, concordance correlation coefficient and root-mean-square error were used to assess the agreement. Maximum allowed differences were defined as 24 %, based on the within-variance coefficient of the energy intake of the sample. Eleven equations were studied. The calculated-TEE obtained by five equations showed non-significant bias: Dietary Reference Intake (Institute of Medicine (2005) Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids), FAO/WHO/UNU ((2001) Food and Nutrition Technical Report Series), Harris & Benedict ((1919) Proc Natl Acad Sci USA4, 370-373), Henry & Rees ((1991) Eur J Clin Nutr45, 177-185) and Schofield ((1985) Hum Nutr Clin Nutr39, 5-41). The mean percentage differences were -1·5, -0·8, 2·2, -2·2 and 2·0 %, respectively. Considering all parameters, FAO/WHO/UNU ((2001) Food and Nutrition Technical Report Series) equation performed slightly better than the others; nevertheless, no equation in conjunction with the estimated-MET showed a calculated-TEE with its CI for the Bland-Altman limits of agreement inside the pre-defined acceptable range.

RESUMEN

BackgroundStunting is still very prevalent in many poor and developing regions in the world. This study assessed the effectiveness of a stunting recovery program in children and its associated factors.MethodsThe retrospective study was conducted in a center of stunting recovery. There, children stayed in a day-hospital system (9 h per day; 5 days per week), and received five meals per day, providing 80% of their energetic daily needs. The main outcome was the stunting recovery rate (i.e., the child present a height-for-age index (HAZ) >-1.0 at the time of data collection). A total of 75 children treated for at least 24 months, aged between 6 and 48 months and with an HAZ <-2.0 at the time of admission were included.ResultsThe average treatment time was 41 months. About 18 children (24.0%) recovered from stunting. The variable "age at admission >24 months" (prevalence rate (PR)=0.39, 95% confidence interval (CI): 0.15-0.99; P=0.04) and the variable "Household crowding index" (PR=0.65, 95% CI: 0.44-0.95; P=0.03) were associated with the success of the treatment.ConclusionThe environmental conditions in which the children live in their households and late admission to the center negatively influenced the success of stunting recovery, even with an intensive treatment.
