Objectives Examine the differences in bone mineral density between normal-weight children and children with overewight or obesity and its association with body composition. Methods In a cross-sectional study, 49 healthy schoolchildren from 6 to 11 years of age attending the outpatient clinic of the Hospital were included. Weight and height were measured for the calculation of the body mass index for age and height for age. The diagnosis of normal-weight, overweight and obesity was made according to the criteria of the World Health Organization. Bone mineral density (BMD) was obtained by dual energy X-ray absorptiometry (DXA). Statistic analysis. The ANOVA test was used to compare mean values between groups. Pearson's correlation to analyze the relationship between BMD and body composition; and multiple regression models to identify associated variables. Results Mean age 8.4 ± 1.7 years; 16 with normal weight, 15 overweight and 18 with obesity. All children had a normal BMD (>–2 Z score). BMD (g/cm2 and Z score) was higher in children with obesity (p < 0.05). Bone mineral content (BMC [g]) and BMD (g/cm2) had a positive correlation with total lean and trunk mass in the three groups (p < 0.001). Fat mass correlated with BMC and BMD in children with normal-weight and overweight, but not in obese children. In multivariate models, total lean mass was the only significant variable within the model that explained the variability of BMD (g/cm2). Conclusions BMD was higher in children with obesity. Lean mass was its most important predictor, which suggests the importance of maintaining the muscular system through the practice of physical activity and healthy lifestyles.

Objectives To demonstrate differences in the profile of biochemical indicators of nutritional status in children with End-stage renal disease (ESRD) between peritoneal dialysis (PD), hemodialysis (HD), and renal transplantation (RT). Methods Analytical cross-sectional study. A total of 130 children and adolescents between 6 and 18 years of age with ESRD were included: 49 children in RT, 33 in PD, and 48 in HD. The biochemical indicators (hemoglobin, glucose, albumin, total cholesterol, and triglycerides) and anthropometric indicators of nutritional status were obtained. ANOVA, T-student, and Pearson correlation were performed. For nonparametric variables, Chi-square, U-Mann Whitney, Kruskal-Wallis, and odds ratio were used. Results The frequency of hypoalbuminemia was higher in the PD group than in the RT group [OR = 56.4 (6.9, 459) P < 0.001] and the HD group [OR = 10.08 (3.1, 319) P < 0.001]. Anemia was higher in the HD group compared with the RT group [OR = 4.9 (2.1, 11.2) P < 0.001] and the PD group [OR = 3.0 (1.3, 7.7), P = 0.02]. Cholesterol serum concentration was higher in the PD group compared to the RT group [OR = 27.4 (3.3, 225), P < 0.01] and the HD group [OR = 26.2 (3.2, 215), P < 0.001]. Patients in the PD group had a higher risk of hypertriglyceridemia than the RT group [OR = 5.5 (1.9, 15.7), P = 0.002] and the HD group [OR = 2.3 (1.1, 5.4), P = 0.04]. Albumin correlated with tricipital skinfold and mid-upper arm circumference (MUAC) in the RT group; with subscapular skinfold (SSF) in the HD group; and with height, SSF, and MUAC in PD group. Conclusions There are substantial differences in the biochemical indicators of nutritional status depending on the renal substitution program.

Objectives To measure appetitive traits (AT) in mother-child dyads with obesity and identify the association between the ATs of the mothers and Body Mass Index (BMI) and the ATs of the child and BMI z-scores (BMIz). Methods In a cross-sectional study children with obesity accompanied by their biological mothers participated at the Hospital. The weight and height of the dyads were measured and mother's completed sociodemographic data and the Spanish versions of the Adult Eating Behaviour Questionnaire (AEBQ-Esp), and the Children Eating Behaviour Questionnaire (CEBQ-Mex). These questionnaires measure stable responses to food known as ATs using 8 subscales (traits). Four food approach traits: Food Responsiveness (FR), Emotional Over-eating (EOE), Enjoyment of Food (EF), and Desire to Drink (DD) (DD in children only); and 4 food avoidance traits: Satiety Responsiveness (SR), Emotional Under-eating (EUE), Food Fussiness (FF) and Slowness in eating (SE). Pearson´s correlations to analyze the associations between the AEBQ-Esp ATs and BMI of the mothers and the CEBQ-Mex ATs and BMIz of the children. Results Data from 308 dyads were collected. The age of the mothers was 36.1 ± 6.9 years, 39% had secondary school level education, 72% were housewives; BMI was 31.8 ± 6.3 kg/m2 and 59% were diagnosed with obesity. The age of the schoolchildren was 9.3 ± 1.8 years, 59.7% boys, and the BMIz were 2.6 ± 1.0 SD. There was a significant positive correlation between EOE and BMI (r = 0.12, P < 0.05). In children, positive significant correlations were found between BMIz and FR (r = 0.23, P < 0.01), EOE (r = 0.29, P < 0.01), EF (r = 0.20, P < 0.01) and DD (r = 0.16, P < 0.05), and negative with SE (r = −0.17, P < 0.01). Conclusions Positive association were observed between food approach ATs and BMIs of the mothers and BMIz of the children; negative associations were found with food avoidance traits and BMIs of the mothers and BMIz of the children, as expected.
