“…These results also showed that current tobacco use increased in this age group (16.2% in 1994, 21.8% in 2002 and 28.9% in 2015, p < 0.0001) as well as meat consumption between 2002 and 2015 and a significant decrease in consumption of fruit and butter. 21 Although this tendency was observed in our results, it is important to identify other factors that could contribute to the presence of asthma symptoms in addition to sex, such as the presence of hay fever or eczema symptoms, which increased the risk for asthma symptoms, according to recent reports in Mexico City. 22 More studies are required to understand the environmental and intrinsic factors that predispose the primary school children and adolescents to develop asthma symptoms, however this study allows us to recognize, with updated information that the prevalence of asthma has been increasing in recent years in four Mexican cities.…”

Background: The Global Asthma Network (GAN) builds on the International Study of Asthma and Allergies in Childhood (ISAAC). Objective: To compare asthma prevalence time trends in primary and secondary school children in four Mexican centers participating in ISAAC and GAN. Methods: GAN is a cross-sectional, multicenter, epidemiological methodology carried out in groups of primary school children aged 6–7 and adolescents aged 13–14 following the ISAAC Phase Three protocol, with additional questions on risk factors and asthma management. Results: Overall, the prevalence of asthma symptoms and diagnosis in primary school children was higher in males than in females both in ISAAC (p < 0.05) and in GAN (p < 0.01), while adolescent females had a higher prevalence, also both in ISAAC (p < 0.001) and in GAN (p < 0.001). Conclusion: The prevalence of asthma and its symptoms has increased from ISAAC Phase Three since 2003 to GAN Phase I in Mexico in 2019. These findings are in line with the increases observed in the centers with low asthma baseline prevalence in ISAAC Phase One in comparison with ISAAC Phase Three.

“…was used as another variable for assessing the proportion of children who smoked cigarettes in the past year and also estimating the trend of the prevalence of smoking in the past 12 months in adolescents from this geographic area since 1994. 14 The questions ''Have you ever tried smoking cigarettes, even one or two puffs?'' and ''How old were you when you smoked a whole cigarette for the first time?''…”

Background: Tobacco-smoking in children is one of the most crucial public health concerns, which could be highly prevalent in underprivileged populations. Methods: A cross sectional, random sampling survey was conducted to determine the prevalence of current tobacco-smoking and related risk factors among adolescents living in a low-income area of Santiago de Chile. Results: Of the 2,747 adolescents participating in the study, 24.0% [95% confidence interval (CI) 22.3-25.5] were current smokers, with no significant difference between girls and boys. Factors associated with current smoking were as follows: positive attitude to smoking cigarettes offered by peers [odds ratio (OR) 8.0; 95% CI 5.7-11.3, P < 0.001], having smoking best friends (OR 4.0; 95% CI 2.6-6.0, P < 0.001), and passive smoking in the house (OR 1.9; 95% CI 1.2-3.1, P = 0.008). A total of 16.8% (95% CI 11.4-18.2) of children had smoked an entire cigarette at the age of £12, and 62.3% (95% CI, 60.5-64.1) were passive smokers at home. Regarding nonsmoking children, 52.4% (95% CI 49.74-55.06) were exposed to tobacco smoke at home. Conclusion:The prevalence of current tobacco-smoking in adolescents is high and increasing compared to previous studies undertaken in the selected low-resourced area. Two-thirds of children who started smoking before the age of 12 years were current smokers at the time of the survey, highlighting the prevalence of the powerful addiction generated and the need for better preventive strategies against tobacco-smoking for children living in low-resource communities.

“…El asma bronquial es la enfermedad crónica más frecuente en la infancia, siendo la prevalencia en niños chilenos de 6 a 7 años de 17.9% y en niños de 13 a 14 años de 15,5% (1). Un estudio reciente en adolescentes de Santiago, muestra una prevalencia de asma de 13,8% (2). En los últimos años la tasa de hospitalización por asma en niños se ha duplicado en nuestro país, siendo el 2014 de 7,8 por 10.000 habitantes (3).…”

La tasa de hospitalización por crisis de asma en niños chilenos se ha duplicado en los últimos años. Diversos estudios muestran una asociación entre hipovitaminosis D y crisis de asma. El objetivo principal del presente estudio fue describir la prevalencia de déficit e insuficiencia de vitamina D (vitD) en escolares asmáticos hospitalizados por crisis de asma y evaluar su estado nutricional. Metodología: Estudio analítico, transversal, que incluyó a todos los pacientes de 5 años o más que se hospitalizaron por crisis de asma durante un año calendario en el Servicio de Pediatría del Hospital Clínico de la Universidad de Chile. Se aplicó una encuesta que incluyó datos sociodemográficos y clínicos, se evaluó el nivel de control del asma mediante el cuestionario Asthma Control Test (ACT), se determinó el estado nutricional y se midió la concentración de vitD. Resultados: Se observó que 6 de cada 10 pacientes presentaba déficit o insuficiencia de vitD (22,8 ng/ml ± 10,5), encontrándose una asociación positiva entre concentración de vitD y ACT. La malnutrición por exceso estaba presente en casi la mitad de los pacientes. Aquellos pacientes que se hospitalizaron por más de 3 días tenían una concentración sérica de vitD significativamente menor. Conclusiones: La hipovitaminosis D afectó a la mayoría de los niños hospitalizados por crisis de asma. Se encontró una asociación significativa entre concentración de vitD con días de hospitalización y control de la enfermedad medido por ACT.
