Nutritional Assessment of the Infant Population of the Chirikyacu Indigenous Community of Peru.

Malnutrition is one of the main public health problems affecting early childhood development, compromising the health and quality of life of thousands of Peruvian children. The main contribution of this work is the analysis of the nutritional status of the infant population of the Chirikyacu Indigenous Community of Peru in order to evaluate current and future food policies. It is a cross-sectional study with a sample of 19 children between 6 months and 6 years of age. Sociodemographic, anthropometric, clinical variables and dietary habits were analyzed from 7 January to 4 February 2018. The mean age of the children was 29.74 months (SD = 23.91). We found statistically significant differences between the BMI values of boys and girls (p < 0.05; Mann−Whitney test). According to the z-scores, 35.29% suffer from malnutrition, although in no case is it severe. Hair, nails and skin were in good condition in general, except for some cases showing signs of nutritional deficiency. Dietary patterns are based on legumes, vegetables, dairy products, ice cream, cookies and sweets, and are considered insufficient to cover basic needs; water intake was also insufficient. Breastfeeding lasted an average of 14 months (SD = 2.9). We found a prevalence of malnutrition higher than that established by the WHO in Latin America among the children of Chirikyacu. The dietary pattern is insufficient to cover basic needs, so it is necessary to continue with nutritional educational interventions to improve it.

Differences in Classification Standards For the Prevalence of Overweight and Obesity in Children. A Systematic Review and Meta-Analysis.

The prevalence of childhood obesity has increased dramatically all over the world in recent years. While obesity in adults can be easily measured using the BMI calculation, determining overweight and obesity in children is more controversial. The aim was to compare the three most used international classification systems (WHO 2007, CDC 2000 and Cole-IOTF) to determine overweight and obesity in infant and adolescent populations. We performed a systematic review in accordance with the PRISMA 2020 guidelines of articles comparing any of the three classification systems. The main findings were that the WHO 2007 criteria show the highest prevalence of overweight and obesity in the child and youth population. The prevalence of childhood overweight and obesity was determined to be higher in boys than in girls in most studies, when analysing the classifications of the WHO 2007, CDC 2000 and Cole-IOTF together. However, there was a higher prevalence of overweight and obesity in girls than in boys when only the CDC 2000 and Cole-IOTF criteria were considered. Both the results of the review and the great heterogeneity found in the meta-analysis show that it is necessary to unify the criteria for the classification of childhood overweight and obesity. International standards are insufficient for working with the current population. A working group should be created to address this issue and agree on the unification of a gold standard, taking into account the geographical region, the ethnic groups and the age groups of the child and youth population and above all, the secular growth.
