Adverse childhood experiences and other risk factors associated with adolescent and young adult vaping over time: a longitudinal study

Background Vaping among adolescents and young adults is a significant public health concern worldwide. Understanding which risk factors are associated with vaping is important to help inform evidence-based prevention and intervention strategies. There are several gaps in the current literature examining these associations such as limited longitudinal research. We examined the association between parental smoking/vaping, adolescent sex, mental disorders in adolescence, 13 adverse childhood experiences (ACEs) and a) any vaping and b) course of vaping across two time points among adolescents and young adults. Methods Data were from Waves 1 and 2 of the longitudinal Well-Being and Experiences Study (The WE Study) in Manitoba, Canada which collected data from a community sample of adolescents (14 to 17 years) and their parent/caregiver in Wave 1 in 2017–18 and the adolescents/young adults only in Wave 2 in 2019. A total of 752 adolescents/young adults (72.4% of the original cohort) completed both waves of the study. Binary and multinomial logistic regressions were conducted to understand the relationship between the 16 risk factors and the two vaping outcomes. Results Vaping prevalence was 45.5% for any vaping, 2.7% for Wave 1 vaping only, 19.7% for new onset Wave 2 vaping, and 21.2% for vaping at both waves. After adjusting for covariates, the majority of risk factors examined were associated with any adolescent or young adult vaping, including: parental smoking or vaping, emotional abuse, emotional neglect, exposure to verbal intimate partner violence, household substance use, household mental illness, parental separation/divorce, parental problems with police, foster care or contact with a child protective organization, an unsafe neighbourhood, and peer victimization. The majority of these risk factors, as well as adolescent mental health and parental gambling, were associated with different courses of vaping across the two time points. Conclusions The findings emphasize the need for early vaping prevention and identified several ACEs and other factors that were associated with adolescent and young adult vaping and course of vaping. These identified ACEs and risk factors can help inform programs, strategies, and potential groups to target for vaping interventions.

Relationship between Parental Smoking and Children’s Pulmonary Function

Purpose: To Study/Understand the Exposure-response Relationship between Parental Smoking and Children’s Pulmonary Function Materials and Method: Participants were selected randomly who fit into the inclusion criteria. Selected participants to be then made understood for the nature of study. Subjects were asked to seat upright on table / stool facing the Spirometer machine. Spirometer was done with the RMH Helios computerized Spirometer. Subjects were asked use nose clip and exhale complete and maximum air for long duration then immediately take deep inspiration followed by complete and maximum expiration for long time. Out of 3 or 4 manoeuvres the best manoeuvre was selected and % predicted of FEV1, FVC, FEV1/FVC, PEFR, FEF25-75 was documented. Results: Statical analysis was done by using Parametric (unpaired t test) and or nonparametric (Mann Whitney) statical test with 95 % class interval (one tailed p). Spearman’s correlation test was obtained to check the relationship between variables. Conclusion: There is a significant reduction in PEFR due to obstructive effect of parental smoking (passive smoking) on pulmonary function of the children. And with increase in number of packs per years, there is a reduction in FEV1, FVC, PEFR and FEF25 -75 of children. Keywords: Passive Smoking, Pulmonary Function, children.

Socio-demographic and Clinical Profile of Children with Asthma attending Chest Clinic at B. P. Koirala Institute of Health Sciences, Nepal

Introduction: Asthma in children is one of the most common chronic diseases and little information available on factors associated with this disease in our part of the world. Objective: The present study is an attempt to find out the socio-demographic and clinical profile of children with asthma. Methodology: This was a retrospective analysis of data of asthmatic children below 14 years attending pediatric chest clinic from July 2014 till March 2016. Results: Of the 200 children, there were 142 (71%) males. The median age of presentation was 3 years and 139 (69.5%) from the age group 1-5years One third had poorly controlled asthma. Comorbidity was present in 59(29.5%) and allergic rhinitis (7%) was the most common. 90.5% had onset of wheezing before 5 years of age. Family history of asthma and/or atopy and smoking was present in 24% and 31%, respectively. 22% had exposure to pet animals. Upper respiratory tract infection (URTI) (37%) was the most common trigger for exacerbation. Cough (99%) and fast breathing (98%) were the most common symptoms. Conclusion: The majorities were males of young age with rhinitis as most common co-morbidity and many of them had a history of parental smoking at home. One third of them had poorly controlled asthma which shows the need for proper management of asthma including its comorbidity in younger children and changing certain habits like parental smoking at home.

P040 Effect of parental smoking on Juvenile Idiopathic Arthritis activity

Background Juvenile idiopathic arthritis (JIA) is an heterogeneous group of autoimmune diseases considered as the main cause of chronic arthritis among children and teenagers. This group of children is thought to be more vulnerable because of chronic inflammation and long-term immunosuppressive therapy. Passive smoking, which is a major health problem, is likely to be particularly harmful for these children whose immunity is already compromised by their disease. The aim of our study was to assess the effect of parental smoking on disease activity in children with JIA Methods A monocentric cross-sectional study of patients with JIA according to the criteria of the International League Against Rheumatism (ILAR) was conducted in the rheumatology department of Kassab Institute. The following clinical and biological data were collected: sex, age, disease duration, BASDAI activity score, functional impairment assessed by the BASFI score, biological inflammation assessed by the erythrocyte sedimentation rate (ESR) and the C-reactive protein (CRP). All parents were contacted and smoking data were recorded: parent smoking, pack-years history, smoking in an indoor or outdoor space, impact of passive smoking on disease activity. We considered any child with at least one smoking parent and living in the same house to be exposed to parental passive smoking. Patients were divided into two groups: group 1 (G1) including patients who are not exposed to parental smoking and group 2 (G2) including patients exposed to smoking by one or both parents. Data were analyzed using SPSS (Statistical Package for the Social Sciences) version 24 software. The significance level was set at a p-value < 0.05. Results Twenty-three patients were included: 15 girls and 8 boys. Sex ratio M/F was 0.53. The mean age was 16.5 + 8.1 years [8–40]. The mean disease duration was 4.9 + 4.9 years [0.15]. The mean ESR was 21.5 + 27.1 mm and the mean CRP was 4.7 + 7.1 mg/l. Nine patients had coxitis, including 4 who were exposed to passive smoking. Passive smoking noted in 11 patients (47.8%), including 6 boys and 5 girls. In 63.6% of the cases, this exposure occurred indoor in the family home. The number of cigarettes smoked per day was 11.7 + 8.4 [1,20]. Among the exposed patients, 36.4% considered that this exposure was an exacerbating factor of their disease. Clinical and biological data were comparable between the 2 groups as shown in table 1. Conclusion Although the adverse effect of maternal smoking during pregnancy on the risk of developing JIA in the child has been demonstrated, few studies have investigated the effect of parental smoking once the disease is established. Our study did not find a statistically significant association between smoking exposure and high disease activity or poor prognosis. However, further studies including a larger number of patients are needed to assess the potential effect of parental smoking on the prognosis of JIA.

Breastfeeding, Nutrition, Parental Smoking And Type 1 Diabetes: A Case-Control Study At Ege University Children's Hospital

Background: It has been suggested that may be a link between many environmental factors, including dietary antigens affecting diabetes epidemiology. The main objective of this study is to investigate nutritional risk factors, especially breastfeeding early in life that may be associated with the development of Type 1 DM and to determine the relationship of these factors with the disease.Methods: The research is a case-control study and was carried out in Ege University Children's Hospital. A total of 248 children aged between 4-14 years were included in the study. The case group was reached from patients diagnosed with Type 1 DM, who applied the Ege University Children's Hospital’s; the control group was reached non-diabetic children applying to the same hospital.Results: The mean age was found 10.4±3.3 years for cases and 7.4±2.5 years for controls. It was found that each monthly increase in exclusive breastfeeding duration provided a 0.78 fold decrease in the risk of Type 1 DM. Introduction of cereals in the diet at 6th month or earlier was associated with an increased risk of 3.42 fold. Each unit increase in the total number of cigarettes that parents smoked at home had increased the risk of Type 1 DM by 1.15 times. Conclusions: Prolonged exclusive breastfeeding duration was found to be a protective factor for Type I DM, while introducing cereals before the 6th month and parental smoking were found an important risk factor, which might be another subject for further studies.
