Food Consumption According to the NOVA Food Classification and Its Relationship with Symptoms of Depression, Anxiety, and Stress in Women.

Background/objectives: Depression, anxiety, and stress are highly prevalent mental disorders worldwide, and food consumption can change in individuals with these conditions. We aimed to assess the food consumption of women with depressive symptoms and compare it to a control without symptoms.

Methods: A cross-sectional study was conducted with 96 women, aged 18-59, allocated into two groups: control = 62) or depressive symptoms ( = 34).

Analysis of heart rate as a predictor of changes in heart rate variability in children.

Objective: To evaluate the predictive validity and cut-off point of heart rate and blood pressure on heart rate variability (HRV) changes in children with and without obesity.

Methods: This study included 125 children, of whom 41 were normal weight and 84 were obese. Anthropometry, blood pressure, heart rate, and HRV were measured using an electronic scale and stadiometer, a sphygmomanometer, and HRV monitor.

High glycemia and resistin normalized in children with double burden of malnutrition: a cross-sectional study.

The coexistence of stunting and excess weight in the same individual is defined as a double burden of malnutrition (DBM) and is associated with noncommunicable diseases. In this study, we evaluated the impact of DBM on adipokine concentrations and metabolic profiles in children compared with weight excess alone. Children were allocated to the weight excess group ( = 23) (height-for-age (HAZ) > 0.

Evaluation of cardiac autonomic function and low-grade inflammation in children with obesity living in the Northeast Brazilian region.

Objective: Evaluate autonomic function and low-grade inflammation and characterize the correlation between these variables in schoolchildren with obesity living in the Brazilian northeast region.

Methods: 84 children with obesity and 41 with normal weight were included in this cross-sectional study. Anthropometry, body composition, blood pressure (BP), inflammatory biomarkers, and heart rate variability (HRV) indexes were analyzed in children aged 7 to 11 years.

Effects of preoperative sarcopenia-related parameters on the musculoskeletal and metabolic outcomes after bariatric surgery: a one-year longitudinal study in females.

Reduced muscle mass and/or strength are risk factors for metabolic and musculoskeletal impairment. The present study evaluated anthropometric, metabolic, and musculoskeletal outcomes in females with and without sarcopenic-obesity parameters who underwent bariatric surgery during a 1-year follow-up. A prospective, single-center cohort study was conducted in females with obesity undergoing preoperative evaluation for surgery.

Coconut Oil Supplementation Does Not Affect Blood Pressure Variability and Oxidative Stress: A Placebo-Controlled Clinical Study in Stage-1 Hypertensive Patients.

Exploring an alternative to improve the clinical management of hypertension, we tested the hypothesis that food supplementation with coconut oil (EVCO), alone or combined with aerobic exercise training, could exert an antihypertensive effect (primary outcome) in patients with stage 1 hypertension. Forty-five hypertensive volunteers of both genders participated in a placebo-controlled clinical trial. The volunteers were submitted to 24-hour ambulatory blood pressure monitoring, analysis of blood pressure variability (BPV), measurement of serum malondialdehyde (MDA) and nutritional assessment.

Food addiction symptoms and metabolic changes in children and adolescents with the double burden of malnutrition.

The double burden of malnutrition (DBM) has been described in many low-/middle-income countries. We investigated food addiction, thyroid hormones, leptin, the lipid/glucose profile and body composition in DBM children/adolescents. Subjects were allocated into groups according to nutritional status: control (C, n 28), weight excess (WE, n 23) and DBM (WE plus mild stunting, n 22).

Changes in Thyroid and Glycemic Status and Food Intake in Children with Excess Weight Who Were Submitted for a Multi-Component School Intervention for 16 Months.

We investigated if children with excess weight who submitted to two types of intervention at school for 16 months showed improvements in thyroid and glycemic function and food intake. Children (8-11 years) with a body mass index-for-age (BMI/A) of ≥1 Z score were divided into two groups: Treatment 1 ( = 73) involved motivation to adopt healthier lifestyle; Treatment 2 ( = 103) involved performing weekly nutritional education, motivational, and physical activities at school. A semi-quantitative food frequency questionnaire was used.

Effect of the use of a model with peer instruction for the teaching of membrane potential and action potential.

A group of teachers from Northeast Brazil developed a model of membrane potentials and action potential and tested the hypothesis that using the peer-instruction model would provide a better performance for students in reading traditional texts and lectures. The results were obtained from 357 students from 20 different courses in 9 different undergraduate programs. All students attended two 100-min theoretical lecture and, at the end of the second lecture, were asked to answer a multiple-choice question (a pretest).

Albuminuria, renal function and blood pressure in undernourished children and recovered from undernutrition.

Background: The objective of this study was to investigate some biomarkers of renal function and blood pressure in children who had recovered from undernutrition.

Methods: This was cross-sectional, comparative study in which a convenience sample of children of both genders (n = 126; age range 6-16 years) treated at the Centre for Nutritional Recovery and Education (São Paulo, Brazil) was used. These children were classified into four groups for analysis: (1) children who were well nourished (control group; n = 50), (2) those showing stunted growth (stunted group; n = 22), (3) those who were underweight (underweight group; n = 23) and (4) those who had recovered from undernutrition (recovered group; n = 31).

Normal cortisol response to cold pressor test, but lower free thyroxine, after recovery from undernutrition.

Undernutrition is a stressor with long-term consequences, and the effect of nutritional recovery on cortisol and thyroid hormone status is unknown. To investigate basal thyroid hormones and the cortisol response to a cold pressor test in children recovered from undernutrition, a cross-sectional study was undertaken on children (6-16 years) separated into four groups: control (n 41), stunted (n 31), underweight (n 27) and recovered (n 31). Salivary cortisol was collected over the course of 10 h: upon awakening, before and after an unpleasant and a pleasant stimulus.

Lower waist circumference in mildly-stunted adolescents is associated with elevated insulin concentration.

Objective: Augmented waist circumference (WC) is associated with non-communicable diseases and could represent a valuable marker in screening for metabolic dysfunctions in subjects with insufficient linear growth. The objective of the present study was to determine whether biochemical and hemodynamic parameters and waist circumference vary between mildly-stunted and non-stunted adolescents from impoverished communities of São Paulo, Brazil.

Methods: The cross-sectional study involved 206 subjects, aged between 9 and 19 years and living in impoverished areas of São Paulo, Brazil.

A 15-year study on the treatment of undernourished children at a nutrition rehabilitation centre (CREN), Brazil.

Objective: To build a life table and determine the factors related to the time of treatment of undernourished children at a nutrition rehabilitation centre (CREN), São Paulo, Brazil.

Design: Nutritional status was assessed from weight-for-age, height-for-age and BMI-for-age Z-scores, while neuropsychomotor development was classified according to the milestones of childhood development. Life tables, Kaplan-Meier survival curves and Cox multiple regression models were employed in data analysis.

Long-lasting effects of undernutrition.

Undernutrition is one of the most important public health problems, affecting more than 900 million individuals around the World. It is responsible for the highest mortality rate in children and has long-lasting physiologic effects, including an increased susceptibility to fat accumulation mostly in the central region of the body, lower fat oxidation, lower resting and postprandial energy expenditure, insulin resistance in adulthood, hypertension, dyslipidaemia and a reduced capacity for manual work, among other impairments. Marked changes in the function of the autonomic nervous system have been described in undernourished experimental animals.

Mild stunting is associated with higher body fat: study of a low-income population.

Objective: To test if individuals having height-for-age z scores between -2 and -1 present higher body fat percentage and, therefore, should not be categorized as having normal nutritional status.

Methods: The study involved 96 individuals (52 boys and 44 girls); 57% of whom had already attained puberty. Body composition was analyzed by dual energy X-ray absorptiometry.

Children recovered from malnutrition exhibit normal insulin production and sensitivity.

Protein-energy malnutrition promotes adaptive hormonal changes that result in stunting. A previous study showed that stunted children had increased insulin sensitivity and diminished pancreatic beta-cell function. The objectives of the present study were to analyse the glucose, insulin, homeostasis model assessment of insulin sensitivity (HOMA-S) and homeostasis model assessment of pancreatic beta-cell function (HOMA-B) levels after nutritional recovery.
