Consensus on complementary feeding from the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition: COCO 2023

Complementary feeding (CF) is defined as the feeding of infants that complements breastfeeding, or alternatively, feeding with a breast milk substitute, and is a process that is more than simply a guide as to what and how to introduce foods. The information provided by healthcare professionals must be up-to-date and evidence-based. Most of the recommendations that appear in the different international guidelines and position papers are widely applicable, but some must be regionalized or adapted to fit the conditions and reality of each geographic zone. The Nutrition Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN) summoned a group of experts from each of the society's member countries, to develop a consensus on CF, incorporating, whenever possible, local information adapted to the reality of the region. The aim of the present document is to show the results of that endeavor. Utilizing the Delphi method, a total of 34 statements on relevant aspects of CF were evaluated, discussed, and voted upon.

Association between free sugars intake and early psychopathological problems

Mental health problems are highly prevalent in childhood and adolescence and may be associated with nutritional intake. It has recently been shown that a high percentage of infants and children consume large amounts of free sugars. In this paper, we analyse the relationship between free sugar consumption at 12 and 30 months and the risk of developing psychological problems at 30 months in a community sample of 86 children evaluated longitudinally. Socio-family and anthropometric data, and the amount of free sugars consumed were collected at both ages. At 30 months, the Child Behavior Checklist 1.5-5 was administered to parents and an interview was conducted to identify psychological disorders in accordance with DC: 0-3's classification. We report a relationship between high free sugar consumption at 30 months and the concurrent presence of sleeping problems, ADHD and anxiety symptoms. However, no significant association was observed between free sugar consumption at 12 months and the subsequent development of psychological problems. Early detection of emotional and behavioural manifestations and high sugar consumption in children may help to prevent the persistence of psychological problems.

Do Children with Autism Spectrum Disorders Eat Differently and Less Adequately than Those with Subclinical ASD and Typical Development? EPINED Epidemiological Study

Food consumption in children with ASD, subclinical ASD and with typical development (TD), and their adequacy to dietary recommendations was studied. A school population sample of 77 children with ASD, 40 with subclinical ASD, and 333 with TD participated. Compared to children with TD, pre-schoolers with ASD consumed fewer raw vegetables and less fish and eggs, while primary school children consumed fewer legumes, raw vegetables, citrus fruits, cheese/yogurt and olive oil, and more meat. All groups consumed an excess of sugar but those with ASD consumed even a greater amount than their peers. The higher prevalence of obesity found in primary school children with ASD may be the consequence of a less healthy eating pattern sustained over time.

High intake of added sugars is linked to rapid weight gain in infancy, breastfeeding ≥12 months may protect against this: A preliminary investigation

BACKGROUND

Consumption of added sugars is linked to excess adiposity in older age groups and breastfeeding has been shown to protect against later obesity.

OBJECTIVES

This investigation aimed to determine whether intake of added sugars associates with rapid weight gain in individuals under 2 years of age, if intake of added sugars associates with breastfeeding duration, and how both influence body weight.

METHODS

A cross-sectional analysis of data from three 24-hours dietary recalls collected from 141 infants/toddlers (age 11.9 ± 1.9 months, 44.7% male) was performed. Multivariable regressions assessed relationships between added sugar intakes, breastfeeding duration, and weight status. Hierarchical regressions examined added variance accounted for in rapid weight gain (specifically, upward weight-for-age percentile [WFA %tile] crossing) through the interaction of added sugars * breastfeeding duration.

RESULTS

Added sugars correlated positively with upward WFA %tile crossing (r = 0.280, P < .001) and negatively with breastfeeding duration (r = -0.468, P < .001). Consumption of added sugars was a significant predictor of rapid weight gain when breastfeeding duration was short (<12 months, β = 0.020, P = .029), but not long (≥12 months, β = 0.001, P = .875).

CONCLUSIONS

A high intake of added sugars in individuals below age 2 associates with rapid weight gain, though breastfeeding ≥12 months appears protective against this. Further studies are necessary to substantiate these findings and provide insight into underlying mechanisms.

[Validation of a short food frequency questionnaire in small children]

Introduction

Introduction: validated food frequency questionnaires in children are scarce, mostly long, and only provide data about food consumption. Objectives: the aim of this study was to evaluate the reproducibility and validity of a short food frequency questionnaire that estimates energy, nutritional intake, and the frequency of food consumption in children aged between 3 and 6 years. Material and methods: in 49 children (57% boys), the reproducibility and validity of a frequency questionnaire with 41 items was assessed using Spearman's and intraclass correlations, both adjusted and not adjusted for energy. A 6-day record was used as a reference method. Results: reproducibility was high in food groups with correlations > 0.70 for most of them and between 0.5 and 0.7 for meat, fish, potatoes, sweets/soft drinks, and oil. For energy and nutrients correlations were > 0.9 and > 0.7, respectively. Validity was strong to moderate for foods with correlations > 0.7 (dairy and milk) and between 0.4 and 0.7 (sausages, eggs, yogur/cheese, vegetables and oil), and for nutrients with correlations > 0.5 (lipids, AGS, AGP, phosphorus, calcium, vitamin E and vitamin C) and between 0.3 and 0.5 (energy, starches, fiber, MUFA, cholesterol, sodium, magnesium, potassium, retinol, riboflavin, niacin, pantothenic acid, vitamin B6 and folates). All correlations were significant and increased after they had been adjusted for energy. Conclusions: the short food frequency questionnaire for children between 3 and 6 years old has high reproducibility and good validity with results that are as good as those of long food frequency questionnaires.
