Relationship between lipid profile, anthropometric indicators, and appetite-regulating hormones in infants according to type of feeding / Relación entre perfil lipídico, indicadores antropométricos y hormonas reguladoras del apetito en lactantes según tipo de alimentación

Background: infants receiving full breastfeeding (FBF) regulate their appetites differently from those receiving human milk substitutes (HMS). In addition, early exposure to the dietary cholesterol in human milk could lead to better cholesterol regulation in later stages of life. Therefore, the purpose was to compare lipid profiles in 4-month-old infants and to correlate lipid profile with anthropometric indicators and appetite-regulating hormones according to the type of feeding. Methods: this was a cross-sectional and correlational study, which included 145 mother-infant dyads according to the type of feeding; 64 received FBF, 47 partial breastfeeding (PBF), and 34 HMS. The complete lipid profile, total ghrelin, leptin, peptide YY, and glucagon-like peptide type 1 were measured. Z-scores for weight/age, length/age, weight/length, triceps (TSF) and subscapular folds (SSF) and body mass index for age were also obtained. Results: there were significant differences in triglycerides and LDL cholesterol according to the type of feeding. In the HMS group, an inverse relationship was observed between ghrelin and triglycerides (p = 0.038), ghrelin and total cholesterol (TC) (p = 0.026), and peptide YY and HDL cholesterol (p = 0.017). In the PBF group, a direct relationship was observed between length/age (z) and triglycerides (p = 0.001) and between subscapular folds and TC (p = 0.049). In infants receiving HMS, a direct correlation was observed between weight/age (z) and TC (p = 0.045) and between length/age (z) and LDL cholesterol (p = 0.010). Conclusion: these findings show a relationship between growth, energy reserve, lipid profile, and modulation of appetite-regulating hormones according to the type of feeding they received. (AU)

Introducción: los lactantes que reciben lactancia materna completa (LMC) regulan su apetito de manera diferente a los que reciben sucedáneos de la leche humana (SLH). Además, la exposición temprana al colesterol en la leche humana conduciría a mejor regulación del colesterol en etapas posteriores de la vida. El propósito fue de comparar el perfil lípidos en lactantes de cuatro meses y correlacionarlo con indicadores antropométricos y hormonas reguladoras del apetito según el tipo de alimentación. Métodos: en un estudio transversal y correlacional se incluyeron 145 díadas madre-lactante según el tipo de alimentación; 64 recibieron LMC, 47 lactancia materna parcial (LMP) y 34 SLH. Se midió el perfil lipídico, grelina total, leptina, péptido YY y péptido tipo 1 similar al glucagón. Se obtuvieron puntajes Z para peso/edad, longitud/edad, peso/longitud, pliegue cutáneo tricipital y subescapular e índice de masa corporal para la edad. Resultados: hubo diferencias significativas en triglicéridos y colesterol LDL según el tipo de alimentación. En el grupo HMS se observó una relación inversa entre grelina y triglicéridos (p = 0,038), grelina y colesterol total (TC) (p = 0,026), y péptido YY y colesterol HDL (p = 0,017). En el grupo PBF hubo relación directa entre longitud/edad (z) y triglicéridos (p = 0,001) y entre pliegues subescapulares y CT (p = 0,049). En los lactantes que recibieron HMS, se observó una correlación directa entre peso/edad (z) y CT (p = 0,045) y entre longitud/edad (z) y colesterol LDL (p = 0,010). Conclusión: los hallazgos muestran una relación entre perfil lipídico, crecimiento, reserva energética y modulación de las hormonas reguladoras del apetito según el tipo de alimentación. (AU)

Association between Maternal and Toddler Appetitive Traits in a Mexican Population.

The Child Eating Behaviour Questionnaire for toddlers (CEBQ-T-Mex) and the Adult Eating Behaviour Questionnaire (AEBQ-Esp) measure appetitive traits (ATs) in children and adults, respectively, both validated for use in Spanish. ATs are inherited variations in appetite, present from birth, that are reasonably stable throughout childhood and can explain why some infants over- or undereat in response to environmental exposures. "Food approach" traits predispose to overweight while "food avoidance" traits provide protection, but little is known about the relationships between parents' and their toddler's ATs. The aim was to examine the associations between maternal and toddler appetitive traits, using the AEBQ-Esp and CEBQ-T-Mex, and to examine the associations between ATs and Body Mass Index z-scores (BMIz). Sociodemographic data and the weights and heights of mothers and toddlers (aged 12-36 months) were collected from a teaching hospital in Guadalajara, Mexico. Mothers completed both the AEBQ-Esp and the CEBQ-T-Mex. Direct correlations were found between the ATs of toddlers and their mother (p < 0.005), except for "Slowness in Eating" (SE), and only an inverse correlation was found between the "Satiety Responsiveness" (SR) of toddlers and their BMIz (r = -0.147; p = 0.007). These results suggest that ATs could potentially run in families. These may be useful targets for family-wide interventions to support the development and maintenance of healthy eating behaviours in childhood.

Anthropometric Indicators and Dietary Intake in Toddlers Aged from 12 to 24 Months Who Attended Private Clinics in the Metropolitan Area of Guadalajara.

The objective was to evaluate the anthropometric indicators and dietary intake of toddlers attending private clinics in Guadalajara. In a cross-sectional study, 101 toddlers aged 12 to 24 months were included. They were born full term, had an adequate weight for gestational age, and attended private clinics in Guadalajara. Two 24 h dietary recalls were administered. Anthropometric measurements were taken, and anthropometric indices were estimated. Student's t test or the Mann-Whitney U test, chi-square test, and odds ratio were used for quantitative or qualitative variables. Males had lower Z scores for the weight/age index than females. During the week, energy intake was excessive in males [OR = 5.5 (95% CI 1.4, 20.8)], and cholesterol intake was insufficient in females [OR = 3.03 (95% CI 1.2, 7.1)]. On weekends, energy [OR = 2.5 (95% CI 1.1, 5.7)] and fiber intake [OR = 3.1 (95% CI 1.2, 7.8)] were insufficient in females. Most of the toddlers who attend the private clinics in the upper-middle socioeconomic stratum of the Guadalajara Metropolitan Area had excessive protein intake, excessive consumption of added sugars was frequent, and there was insufficient intake of vitamin D and calcium. Sex was shown to be a factor influencing nutrient intake in these toddlers aged 12-24 months. Males had a Z-score of weight/age lower than females, suggesting nutritional risk.

Gurka vs Slaughter equations to estimate the fat percentage in children with cerebral palsy from all subtypes and levels of the Gross Motor Function Classification System.

BACKGROUND: Body composition assessment in children with cerebral palsy (CP) is a challenge, specially the fat percentage. There are different methods that can be used to estimate the fat percentage in this population, such as anthropometric equations, but there is still a need to determine which is the best and most accurate. The purpose of the study was to determine the method that best estimates the fat percentage in children from all CP subtypes and levels of the Gross Motor Function Classification System (GMFCS). METHODS: Analytical cross-sectional study in which 108 children with CP diagnosed by a pediatric neurologist were included with any type of dysfunction and from all levels of the GFMCS. Slaughter equation, Gurka equation and Bioelectrical impedance analysis (BIA) as reference method, were used. Groups were stratified by sex, CP subtypes, GMFCS level and Tanner stage. Median differences, Kruskal-Wallis, Mann-Whitney U test, Spearman's correlation coefficients and simple regressions were used, also multivariate models were performed. RESULTS: The Slaughter equation differed from the other methods in the total population and when it was compared by sex, CP subtypes, gross motor function and Tanner stage. The Gurka equation showed significant differences by sex and gross motor function. Gurka equation correlated positively and significantly with BIA to estimate the fat percentage in all the CP subtypes and levels of the GMFCS. Tricipital skinfold (TSF), arm fat area (AFA) and weight for age index (W/A) showed the highest variability with respect to fat percentage. CONCLUSION: Gurka equation is more appropriate and accurate than Slaughter equation to estimate the fat percentage in children with CP from all subtypes and levels of the GMFCS.

Firmicutes, Bacteroidetes and Actinobacteria in Human Milk and Maternal Adiposity.

The main objective was to explore the relationship between the microbiota of human milk and adiposity in Mexican mothers during the first lactation stage. METHODS: Seventy lactating women were included. Adiposity by anthropometric measurements and by bioelectric impedance was obtained. The donation of human milk was requested, from which bacterial DNA was extracted and qPCR of the 16S region was performed. The Mann-Whitney U test, Spearman and Pearson correlations, and multiple linear regressions models were also calculated. RESULTS: The median percentage of Bacteroidetes had a direct and significant correlation with normal adiposity, current BMI, waist circumference, and body fat percentage. The correlation with current BMI became significantly inverse in women with BMI ≥ 25. In women with normal BMI, the percentage of Actinobacteria showed a direct and significant correlation with current BMI, waist circumference, and percentage of body fat. Multiple linear regressions showed that pre-pregnancy BMI was the variable with the highest predictive value with the Bacteroidetes phyla in normal BMI and in BMI ≥ 25. CONCLUSIONS: the adiposity of the woman before pregnancy and during lactation would have an important effect on the abundance of Bacteroidetes and Actinobacteria in human milk.

Bilateral asymmetry in arm anthropometric measurements according to laterality and nutritional status in children and adolescents from 6 to 12 years old.

OBJECTIVE: To compare and correlate anthropometric measurements of the left arm versus the right arm and to establish their relation to laterality, sex, and nutritional status in children and adolescents from 6 to 12 years of age. METHODS: A cross-sectional study included 605 children and adolescents (285 males; 320 females), with a middle socioeconomic status, that attended an urban elementary school. Anthropometric measurements were taken in both arms, along with height and weight, to assess nutritional status. Self-reported hand preference was recorded. RESULTS: A total of 49.3% were females and 93% of the subjects were right-handed (n = 563). The mean comparison of right arm and left arm measurements and areas, according to laterality, showed differences in arm fat measurements, with higher values in the right arm. However, the mean difference in triceps skinfold and upper arm measurements between the right arm and left arm was smaller than the technical error of measurement. Significant differences were observed between arm measurements and areas. Upper arm and total upper arm areas of both arms had the highest regression coefficients, with an adjusted R2 of .98, whereas the arm fat index had the lowest (adjusted R2 of .88). Adjusting the previous differences between the right arm and left arm by age, sex, BMI, and laterality produced similar results. CONCLUSIONS: Statistical but not clinically significant differences were found between some measurements and areas of both arms, discretely modified in models adjusted for age and BMI, so the measurements can be made on either arm.

Secondary Malnutrition and Nutritional Intervention in Cholestatic Liver Diseases in Infants.

We aimed to conduct an updated review on the pathophysiology, diagnosis, and nutritional intervention of CCLD and secondary malnutrition in infants. Protein-energy malnutrition, impaired linear growth, fat-soluble vitamin deficiencies, and hepatic osteodystrophy can occur in up to 80% of cases. The proposed pathophysiological mechanisms include insufficient energy intake, lipid- and fat-soluble vitamin malabsorption, increased energy expenditure, altered intermediate metabolism, hormonal dysregulation, and systemic inflammation. The current approach to diagnosis is the identification of the deviation of growth parameters, body composition, and serum concentration of micronutrients, which determines the type and magnitude of malnutrition. Currently, liver transplantation is the best therapeutic alternative for the reversal of nutritional impairment. Early and effective portoenteroanatomosis can extend survival in patients with biliary atresia. Medical and dietary interventions in some storage and metabolic diseases can improve liver damage and thus the nutritional status. A proportion of patients with biliary atresia have fat-soluble vitamin deficiencies despite receiving these vitamins in a water-soluble form. With aggressive enteral nutrition, it may be possible to increase fat stores and preserve muscle mass and growth. The nutritional issues identified in the pre- and post-transplantation stages include muscle mass loss, bone demineralization, growth retardation, and obesity, which seems to correspond to the natural history of CCLD. Due to the implications for the growth and development of infants with CCLD with this complex malnutrition syndrome, innovative projects are required, such as the generation of prediction and risk models, biomarkers of growth and body composition, and effective strategies for nutritional prevention and intervention.

Validity and Reliability of the Baby and Child Eating Behavior Questionnaire, Toddler Version (BEBQ-Mex and CEBQ-T-Mex) in a Low Sociodemographic Sample Recruited in a Mexican Hospital.

The objective of this study was to validate and measure the internal reliability of the Baby and Child Eating Behavior Questionnaires for Toddlers (BEBQ-Mex and CEBQ-T-Mex), that evaluate appetitive trait (ATs). Mothers recruited from a public hospital in Guadalajara, Mexico, completed the BEBQ-Mex or CEBQ-T-Mex along with information on sociodemographic characteristics. Internal reliability of the BEBQ-Mex was sufficient for Food Responsiveness (FR) (Cronbach α = 0.82), while Enjoyment of Food (EF) and Satiety Responsiveness (SR) showed poor reliability (α = 0.56) and Slowness in Eating (SE) had unacceptable reliability (a = 0.36). All reliability values for the CEBQ-T-Mex were acceptable (>0.70), except for SE (α = 0.64). Confirmatory factor analysis (CFA) revealed an adequate model fit for the BEBQ-Mex, except the SE subscale. CFA for the CEBQ-T-Mex confirmed the six-factor structure. Mothers of a low sociodemographic background were unable to recognize their infants' ATs; the BEBQ-Mex partly met the criteria for validity and reliability. Mothers from similar sociodemographic characteristics were more able to recognize the ATs of their toddlers than their infants; the CEBQ-T-Mex was found to be a valid and reliable tool. Findings support the need to help mothers' ability to recognize their infants' ATs, which have been previously associated with weight and growth.

Influence of Breastfeeding Factors on Polyamine Content in Human Milk.

The polyamine content of human breast milk, which is the first exogenous source of polyamines for the newborn, can be affected by several factors associated with the mother, the infant, or breastfeeding itself. The aim of this study was to evaluate the influence of different breastfeeding factors on the polyamines found in human milk. For this study, a cohort of 83 mothers was considered for up to 4 months, and a subgroup of 33 mothers were followed during the first six months of breastfeeding. Two breast milk samples were collected at each sampling point (foremilk and hindmilk) and the polyamine content was determined by UHPLC-FL. Polyamine levels varied considerably between the mothers and tended to decrease over time. Putrescine was the minor polyamine, whereas spermidine and spermine contents were very similar. The concentrations of the three polyamines were significantly higher in hindmilk than foremilk (p < 0.001). Spermidine and spermine levels decreased significantly through the lactation progress (p < 0.05). Finally, slightly higher levels of polyamines were observed in the milk of mothers providing partial, rather than full, breastfeeding, although the differences were not significant. The polyamine content in human milk was found to change during a single feed (foremilk versus hindmilk) and as lactation progressed, mainly in response to the specific circumstances of the newborn.

Percentile Reference Values for the Neck Circumference of Mexican Children.

Neck circumference was studied for the first time in a pediatric population in 2010. Since then, various countries have proposed cutoff values to identify overweight, obesity, and metabolic syndrome. However, no reference values have been established for the Mexican child population. The aim of this study is to provide percentile reference values for the neck circumference of Mexican schoolchildren. Only normal-weight schoolchildren aged 6-11 years were included. Percentiles and growth charts were constructed based on the "Generalized Additive Model for Location, Scale and Shape" (GAMLSS). A total of 1059 schoolchildren (52.9% female) was evaluated. Weight, height, and BMI values were higher for males; however, this difference was not statistically significant. The 50th percentile for females was 24.6 cm at six years old and 28.25 cm at 11 years old, and for males, it was 25.75 cm and 28.76 cm, respectively. Both males and females displayed a pronounced increase in neck circumference between 10 and 11 years of age. The greatest variability was found in the 11-year-old group, with an increase of 5.5 cm for males and 5.4 cm for females. This study presents the first reference values for neck circumference for a Mexican child population.

Influence of the Type of Breastfeeding and Human Milk Polyamines on Infant Anthropometric Parameters.

Feeding choices in the early months of life are key determinants of growth during infancy. Polyamines participate in cell proliferation and differentiation, and it has also been suggested that polyamine metabolism plays a role in adipogenesis. As the main exogenous source of polyamines in the infant is human milk, the aim of this work was to study if the type of breastfeeding received and the polyamine intake from human milk has an influence on infant anthropometric parameters. A cohort of 78 full-term healthy newborns was followed up until 4 months of age; 55 were fully and 23 partially breastfed. Anthropometric measurements were taken at 2 and 4 months, when human milk samples were also collected for analysis of polyamine content by UHPLC-FL. Fully breastfed infants had a better anthropometric profile than those partially breastfed (p < 0.05). Furthermore, polyamine intake in partially breastfed infants was significantly lower compared to those fully breastfed. However, only two of the 15 anthropometric indicators evaluated (triceps skinfold and mean upper arm circumference) showed a significant inverse association with polyamine content in human milk and intake (p < 0.05). Infant growth and body composition differ according to the type of breastfeeding received. Based on the weak associations between polyamines and anthropometric indicators, it is not possible to conclude the influence of polyamines in infant growth and body composition.

Full Breastfeeding Modifies Anthropometric and Body Composition Indicators in Nursing Mothers.

Background: It has been observed that breastfeeding mobilizes the deposits of fat that accumulate during pregnancy and promotes weight loss through energy expenditure. The purpose of this study was to demonstrate that full breastfeeding (FBF) reduces anthropometric and body composition indicators in women between the 8th and the 16th week postpartum. Methods: In a nonrandom cohort study, 170 mothers at the Hospital Civil de Guadalajara, Guadalajara, México, were enrolled: FBF 74, partial breastfeeding (PBF) 57, and human milk substitutes (HMS) 39. Anthropometric indicators and body composition were measured at the 8th and 16th week postpartum. We performed analysis of variance to compare body composition according to the type of feeding and paired Student's t-test to compare the changes from the 8th to 16th week postpartum. Results: We found that FBF mothers had a trend to lower arm fat area and triceps skinfold than PBF and HMS mothers at 8 and 16 weeks postpartum. We observed a decrease in weight (p = 0.004), weight/age index (p = 0.003), body mass index (p = 0.003), hip circumference (p = 0.037), and lean mass (p = 0.003) from 8 to 16 weeks postpartum in mothers who offered FBF. The mid-upper arm circumference, the arm total area, and their z-score increased in the three feeding groups. Conclusions: Our results show that FBF mothers had some lower adiposity from 8 to 16 weeks postpartum compared with the result observed among PBF mothers and those who utilized HMS.

Using a lactation room at the workplace is associated with longer breastfeeding duration in working mothers / El uso de una sala de lactancia en el lugar de trabajo se asocia a una mayor duración de la lactancia en las madres trabajadoras

INTRODUCTION: maternal employment after childbirth is associated with abandonment of breastfeeding; however, lactation rooms in the workplace increase the practice of breastfeeding. OBJECTIVE: to compare the frequency and duration of breastfeeding among working mothers based on the presence of lactation rooms in their workplaces. METHODS: we included mothers from different institutions whose infants were between 6 and 35 months (n = 158), and an ad hoc questionnaire was applied to assess breastfeeding, exclusive breastfeeding (EBF), partial breastfeeding (PBF), and use of human milk substitutes (HMS). Two groups were compared: working mothers with a lactation room at their workplace (n = 76) versus working mothers without this resource (n = 82). RESULTS: breastfeeding duration (7.5 vs. 5.0 months, p < 0.001) and EBF (3.0 vs. 1.2 months, p = 0.005) were higher in mothers who had a lactation room. HMS use was shorter in mothers who had a lactation room (2.5 vs. 10.0 months, p = 0.001). There were more working mothers who breastfed for more than six months (75.0 % vs. 48.8 %) [OR = 3.15 (95 % CI, 1.60-6.19), p = 0.001] and 12 months (31.6 % vs. 14.6 %) [OR = 2.69 (95 % CI, 1.23-5.87), p = 0.014] when lactation rooms were available in their workplaces. CONCLUSION: the presence of a lactation room in the workplace was associated with a higher frequency and duration of breastfeeding

Appetite-regulating hormones and anthropometric indicators of infants according to the type of feeding.

It has been accepted that satiety- and appetite-stimulating hormones play a role in the regulation of food intake and body composition during and after the lactation stage. Therefore, the purpose was to demonstrate that serum appetite-regulating hormones in infants differ according to anthropometric indicators and type of feeding. In a nonrandom cohort study, 169 mother-newborn dyads whose pregnancy and birth were attended at the Hospital Civil de Guadalajara were enrolled. According to the type of feeding, infants were classified as full breastfeeding (FBF), partial breastfeeding (PBF), and infants receiving human milk substitutes (HMS). Serum concentrations of ghrelin (pg/ml), leptin (ng/ml), peptide YY (pg/ml), and glucagon-like peptide-1 (GLP-1) (pM) were measured. Anthropometric measurements including weight, length, cephalic, arm circumference, tricipital, and subscapular skinfolds were obtained. Weight/age, weight/height, height/age, and BMI Z-score indexes were estimated. We performed one-way ANOVA, unpaired Student's t test, post hoc Tukey test, and Pearson correlation tests. The ANOVA comparison of the three feeding types showed significant differences in most anthropometric indicators (z-scores), especially between infants receiving FBF versus HMS and particularly on indicators of adiposity; no differences were observed in length and cephalic circumference z-scores at 8th and 16th weeks. Further, significant correlations were found between most of the adiposity indicators with ghrelin, leptin, and GLP-1, especially in infants who received FBF. There were differences in anthropometric and body composition parameters among infants receiving FBF, PBF, and HMS. There were significant correlations between body composition indicators with ghrelin, leptin, and GLP-1 mainly in infants receiving FBF.
