Objective. To determine the concordance between five diagnostic criteria for metabolic syndrome (MS) among teenagers from a Peruvian high Andes region. Materials and methods. A cross-sectional study was carried out with secondary data from an intervention study in two public schools in 2019. We included 397 teenagers who lived in the city of Cajamarca, in the Andean region of Peru. We applied the criteria from the Adult Treatment Panel III (ATP-III) modified by Cook, the International Diabetes Federation (IDF), the American Heart Association (AHA), Ferranti, and the World Health Organization (WHO). The point prevalence and interval prevalence were estimated with the five criteria. The Kappa concordance coefficient with an 95% confidence interval (95%CI) was estimated. Results. The Ferranti criterion identified 17.1% (95%CI: 13.4 to 20.8) of teenagers with MS, followed by the ATP-III criterion with 4.3% (95%CI: 2.3 to 6.3); the other criteria identified a lower frequency. The best concordance was found between the AHA and ATP-III criteria (k = 0.905); the WHO and IDF criteria had a coefficient of 0.628. The five criteria coincided in classifying six adolescents (1.5%) as MS. Conclusions. The AHA and ATP-III criteria modified by Cook had almost perfect concordance, which was also found for both sexes. The ATP-III, Ferranti, IDF, AHA and WHO criteria agree in less than 2% when identifying MS in the same group of adolescents. [ABSTRACT FROM AUTHOR]

Introduction: The association between intimate intimate partner violence against women and chronic malnutrition in children has not been clearly established. Many conceptual frameworks of child malnutrition do not considered domestic violence as a determinant. Objective: To evaluate the association between intimate intimate partner violence against women and chronic malnutrition in children under 5 years of age. Methods: We conducted a study of secondary data based on the Demographic and Family Health Survey 2020 of Peru. We estimated the odds ratio crude and adjusted with a binary logistic regression that considered as exposure to intimate intimate partner violence and dependent variable to chronic malnutrition, also we included 16 covariates of interest selected from the relevant literature. Results: We included data from 8980 women and their children. The chronic malnutrition prevalence in children under 5 months of age was 10.7% (95% CI 9.8 to 11.7). We found no association between chronic malnutrition in children and emotional violence (aOR: 0.98, 95% CI: 0.72 to 1.32), severe physical violence (aOR: 1.02, 95% CI: 0.62 to 1.68), and sexual (aOR: 0.94, 95% CI: 0.50 to 1.77) against mothers. Conclusions: These results add to the evidence that supports the absence of association between the three types of intimate partner violence as risk factors of chronic malnutrition in children under 5 years of age and highlight the importance of other variables such as the mother's educational level.

Objective. To estimate the impact of a school-based nutritional and healthy lifestyle intervention to increase the proportions of adolescents free of components of the metabolic syndrome. Materials and methods. We performed a pre-experimental study in a representative sample of adolescents from two schools in a high Andean district of Peru (Cajamarca city); 388 students completed the intervention and the baseline and post-intervention measurement. The intervention had nine thematic modules; each module was developed in an educational session of 45 minutes every two weeks. We used the National Cholesterol Education Program Expert Panel and Adult Treatment Panel III criteria to identify metabolic syndrome. We used paired proportions comparison (McNemar test) to determine the impact of the intervention. Results. At baseline, 20.4% (95% CI: 16.2 to 24.5) students had no metabolic syndrome components, post-intervention this proportion increase to 32,5% (95% CI: 27.7 to 37.3), the difference in proportions was 12.1% (95% CI: 7.5 to 16.8; p<0.001). The prevalence of metabolic syndrome was 4.6% (95% CI: 2.4 to 6.9) at baseline, while post-intervention was 2.3% (95%CI: 0.7 to 3.9). In the analysis of components, the greatest reduction was in the proportion of hypertriglyceridemia (difference proportions: 21.9%, 95%CI: 16.9 to 26.9, p <0.001), also we found a significant reduction in arterial hypertension (difference proportions: 3.1%, 95% CI: 0.6 to 5.6, p=0.025). In the other components, there were no significant differences. Conclusions. The school-based intervention increased in 59.3% the proportion of students free of any component of the metabolic syndrome. [ABSTRACT FROM AUTHOR]
