Filter by:According to the "China Smoking Health Hazard Report 2020", the total number of smokers in China is estimated to be 350 million, of which 180 million are already addicted. In addition, more than 700 million nonsmokers are exposed to secondhand smoke and become passive smoking victims, among which the family is one of the main places of secondhand smoke exposure, and mothers and children are the most affected group. Passive smoking is a risk factor for spontaneous abortion in pregnant women and an important risk factor for the occurrence of gestational hypertension syndrome and pregnancy complications, and it also affects embryonic development with adverse pregnancy outcomes such as miscarriage, stillbirth, intrauterine growth retardation, preterm birth, immune deficiency, birth defects, and mental retardation. Helping smokers quit is the fundamental solution to reducing secondhand smoke exposure. The accessibility and effectiveness of traditional offline smoking cessation intervention services do not meet the needs of society. With the development of mobile communication technology, digital cessation such as SMS cessation, WeChat cessation, and APP cessation have emerged, which combine clinical cessation guidelines with software technology and present rich product features and interactive design, providing a new solution to expand the accessibility of clinical cessation interventions and address the problem of secondhand smoke exposure.We hope to explore the impact of different digital cessation tools and their combinations on reducing smoking prevalence and maternal tobacco exposure.
The purpose of the present study was to determine the effect of passive smoking on oxidative stress and dental caries in children.A total of 180 children were included to the study as follows; 90 children exposed to passive smoking, and 90 children in the control group (unexposed controls). Also demographic data were recorded (age, gender, parental education levels, child's tooth-brushing habit and child's daily dietary sugar exposure, family income). Dental examination of children were performed and caries prevalence of the patients were recorded. Unstimulated saliva samples were collected from children. Saliva 'cotinine levels' and oxidative stress markers 'total antioxidant status' (TAS), and' total oxidant status' (TOS) were evaluated by using Enzyme-linked immunosorbent assay (ELISA). The obtained data parameters of the two groups were evaluated and comparison was performed.
The aim of the present study was to determine the effect of passive smoking on the levels of salivary TAS, TOS, LL-37 and dental status in children.In the study the parents of children were asked to fill out a complete survey about smoking habits. After filling out the questionnaire, according to the survey results, a total of 180 children were included to the study as follows; 90 children exposed to passive smoking, and 90 children in the control group (unexposed controls). Also demographic data were recorded (age, gender, parental education levels, child's tooth-brushing habit and child's daily dietary sugar exposure, family income). Dental examination of children were performed and caries prevalance of the patients were recorded. Unstimulated saliva samples were collected from children. Saliva 'cotinine levels' which are expected to increase in passive smoking group; 'antimicrobial peptide LL-37' and oxidative stress markers 'total antioxidant status' (TAS), and' total oxidant status' (TOS) were evaluated by using Enzyme-linked immunosorbent assay (ELISA). The obtained data parameters of the two groups were evaluated and comparison was performed.
The primary goal of this research is to evaluate the effectiveness of an intervention for parents to reduce tobacco smoke exposure of young children
The study will examine changes in the respiratory system mechanics and in respiratory physiology after exposure of subjects to passive smoking. It is about healthy non-smoking volunteers and it will be carried out through the techniques of forced oscillation with Impulse Oscillometry (IOS) technique methodology and nitrogen washout. The present study will contribute to the understanding of passive smoking consequences on the respiratory system of healthy non-smokers. Thanks to the nitrogen washout technique, changes to closing volume and closing capacity will be examined during measurement in different positions (sitting, decubitus) together with exposure to passive smoking. With IOS methodology, changes in respiratory system resistance in four positions (standing, sitting, right and left lateral decubitus) will be evaluated before and after exposure to a passive smoking environment. Results of the present study are expected to provide interesting information on the changes in measured parameters not only in different positions but also after exposure to smoking.
Background: Infants are at risk for tobacco-attributable diseases by being exposed to environmental tobacco smoke (ETS). International literature has shown that a home smoking ban can reduce ETS. The purpose of this study is to examine whether a brief feedback about urinary cotinine in infants and a counselling session about the consequences of ETS leads to a reduction of ETS. All families with children up to an age of three years in the study region will be contacted by mail and asked for participation in this study. They will be randomised into an intervention and one control group. The intervention group will receive a ETS counselling session and detailed analysis of urinary cotinine (a biomarker of ETS) at their home. They will further receive written feedback approx. 2 weeks later. The control group will be visited and will answer a questionnaire and will receive brochures about ETS. They will receive a standard analysis feedback of urinary cotinine. There will be oine further assessment/ visit 12 months later. The outcome of this study is an anlysis of urinary cotinine and smoking behaviour and changes in cotinine and smoking behaviour.
