Abstract

Introduction: Childhood obesity is a serious public health problem in Mexico. A nutritional intervention program (NIP) and the construction of nutritional status index for its prevention, can prevent non-communicable diseases in adulthood; and communicable ones such as COVID-19.

Objective: Apply a Principal Component Analysis (PCA) to evaluate the effect of a NIP in overweight and obese pediatric patients.

Methodology: 50 children between the ages of 7 and 13 years old participated. A clinical record and a nutritional diagnosis were prepared. A descriptive analysis was made using measures of central tendency, dispersion, and variable association; Pearson's correlations, Student's “t” tests for paired samples, univariate analysis of variance (ANOVA), multivariate (MANOVA) and a Cluster analysis were performed to form groups of children with similar multivariate behavior. A nutritional index (NI) was obtained for the patients using a PCA.

Results: The NIP showed a statistically significant effect (p ≤ 0.05) on anthropometric response variables. The weight mean decrease 9.7 ± 0.3 Kg. The intestinal habit and age significantly affected (p ≤ 0.01) the “Change in Weight” and the “Change in BMI” variable. The fast-food intake frequency and sweetened drinks decreased. Using the PCA, two components were selected that explained 94.9% of the total nutritional variation observed in the patients.

Conclusion: At the end of the NIP, the multivariate behavior of pediatric patients changed positively and the dispersion of children in the variables involved decreased.
