Evaluation of Cardiovascular Risk by Waist-to-Height Ratio in School-Age Children.

Background: Childhood overweight and obesity are among the major public health problems worldwide. In Mexico, it has been reported in 2018 that 35.6% of children between 5 and 11 years old were overweight or obese. Central obesity is associated with the development of different complications, such as cardiovascular diseases (CVDs). An important tool used to evaluate obesity is the waist-to-height ratio (WHtR), and values higher than 0.5 suggest the existence of cardiovascular risk (CVR). The aim of this study was to evaluate CVR by the WHtR in school-age children from Yucatan, Mexico. Methods: This study included a sample of school-age children between the ages of 10 and 13 years from public schools in Yucatan, Mexico. Anthropometric parameters such as body weight, height, body mass index z-score (zBMI), waist circumference, WHtR, and CVR were evaluated. Results: A total of 2559 children with a median age of 12.1 ± 0.57 years old were evaluated. The classification by height z score showed that 26.8% were of short height, 73.1% were of normal height, and 0.1% were of tall height. The prevalence of body weight excess determined by zBMI was 48%. The prevalence of normal weight was 44%, and the prevalence of body weight deficiencies was 8%. The CVR determined by WHtR was 47.5%. In the population with obesity, 63.3% had an increased risk of CVDs and 30.7% had a very high risk. Moreover, it was observed that 13.2% of the population with normal weight had an increased risk of CVDs. Conclusion: One out of two child 10 to 13 years of age is overweight or obese as defined with zBMI in Mexico. According to WHtR, almost half of this population is at increased CVR, while near two-third of child with obesity are at high or very high CVR.

Thoracoscopic anatomical resection of congenital lung malformations in adults.

Congenital lung malformations (CLM) are a heterogeneous group of disorders that may require surgical resection to prevent complications. Thoracoscopic resection of CLM has been reported in infants. Our goal was to state whether it can also be a viable option in adults. Between 2007 and 2014, 11 patients had a thoracoscopic resection of a CLM (six lobectomies and five anatomic segmentectomies) with satisfactory results. Although being more challenging in adults due to infectious sequellae, this approach is safe.

The impact of public expenditure on undernourishment distribution in Mexico.

The status of undernourishment in children under the age of five in Mexico is open to debate. Linked to poverty, underweight and stunting, the rates of undernourishment are reported to be diminishing, although poverty remains an incessant problem. This study was done to determine whether there is an association between public expenditure and underweight and stunting distribution in Mexico based on data from the 2006 health and population census and from macroeconomic, social, and demographic variables. We used principal component analysis to reduce the number of variables and analyze their behavior. Multiple regressions showed that underweight and stunting are significantly associated with the marginalization index, support from the Sistema Nacional para el Desarrollo Integral de la Familia (DIF) supplies and breakfast program, the gross domestic product per capita, and expenditure from the Opportunities program. Further, public expenditure aimed to combat undernourishment is inadequately oriented to address the needs of the poor.

Overweight and obesity in school children aged 5 to 11 years participating in food assistance programs in Mexico.

OBJECTIVE: To determine the association between overweight and obesity among Mexican school-aged children and participation in the Liconsa milk and the School Breakfast food assistance programs. MATERIAL AND METHODS: Data from 15 003 school-aged children included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) were analyzed. Information on body mass index (BMI) and participation in food assistance programs was obtained. Descriptive analyses were conducted and logistic regression models were adjusted. RESULTS: Prevalence of overweight and obesity was 17.3% and 9%, respectively. No significant association between overweight and obesity and participation in Liconsa was found. Among school-aged children in the middle socioeconomic status quintile, those enrolled in the School Breakfast program were more likely to be overweight than those not enrolled (OR= 1.6, 95% CI 1.1, 2.3). CONCLUSIONS: We found no association between the Liconsa and the School Breakfast programs and overweight or obesity in school-aged children.

Overweight and obesity in school children aged 5 to 11 years participating in food assistance programs in Mexico / Sobrepeso y obesidad en niños de 5 a 11 años de edad beneficiarios de programas de ayuda alimentaria en México

OBJECTIVE: To determine the association between overweight and obesity among Mexican school-aged children and participation in the Liconsa milk and the School Breakfast food assistance programs. MATERIAL AND METHODS: Data from 15 003 school-aged children included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) were analyzed. Information on body mass index (BMI) and participation in food assistance programs was obtained. Descriptive analyses were conducted and logistic regression models were adjusted. RESULTS: Prevalence of overweight and obesity was 17.3 percent and 9 percent, respectively. No significant association between overweight and obesity and participation in Liconsa was found. Among school-aged children in the middle socioeconomic status quintile, those enrolled in the School Breakfast program were more likely to be overweight than those not enrolled (OR= 1.6, 95 percent CI 1.1, 2.3). CONCLUSIONS: We found no association between the Liconsa and the School Breakfast programs and overweight or obesity in school-aged children.

OBJETIVO: Determinar la asociación entre el sobrepeso y la obesidad en niños de edad escolar y la pertenencia a los programas de asistencia alimentaria Liconsa o Desayunos Escolares en México. MATERIAL Y MÉTODOS: Se analizó la información de 15 003 niños en edad escolar de la Encuesta Nacional de Salud y Nutrición 2006 (ENSANUT 2006). Se obtuvo el índice de masa corporal (IMC) e información sobre participación en programas de asistencia alimentaria. Se realizaron análisis descriptivos y se ajustaron modelos de regresión logística. RESULTADOS: La prevalencia de sobrepeso y obesidad fue de 17.3 y 9 por ciento, respectivamente. No hubo asociación significativa entre el sobrepeso y obesidad y ser beneficiario de Liconsa. En el quintil socioeconómico medio, los beneficiarios de Desayunos Escolares tuvieron mayores posibilidades de presentar sobrepeso que los no beneficiarios (RM= 1.6, IC 95 por ciento 1.1,2.3). CONCLUSIONES: No se encontró asociación entre ser beneficiario de Liconsa o Desayunos Escolares con el sobrepeso y obesidad en este grupo de edad.
