Effect of occupation and smoking on respiratory symptoms in working children

The risk factors for chronic cough in children: A meta-analysis covering five continents

BACKGROUND

This study aimed to explore the risk factors for chronic cough in children and provide a reference for prevention and healthcare measures.

METHODS

PubMed, Web of Science, Cochrane, and EMBASE were searched for observational studies published up to April 2024. Outcome included risk factors associated with chronic cough in children. Two investigators independently searched and screened the literature, evaluated the qualities and extracted baseline datas. Results were analyzed using random-effects models with odds ratios and their 95 % confidence intervals to address heterogeneity. Subgroup analyses, sensitivity analyses and assessment of publication bias were performed. Stata17 and GRADEwas used for the meta-analysis.

RESULTS

18 studies including 97,462 children were reviewed. Asthma(OR = 4.06, 95%CI: 2.37-6.96, P＜0.01), NO2(OR = 1.19, 95%CI: 1.01-1.39, P = 0.031), Home remodeling history (OR = 1.82,95 % CI: 1.61-2.05, P＜0.01), Environment Tobacco Smoke(OR = 1.41, 95 % CI: 1.15-1.73, P = 0.001), Pet exposure (OR = 1.56, 95%CI: 1.25-1.95, P＜0.01), Mould (OR = 1.64,95%CI: 1.45-1.85, P＜0.01), Age＜1 year(OR = 3.19, 95 % CI: 1.8-5.63, P＜0.01) were reported as risk factors for chronic cough in children, these results were discussed qualitatively in the study.

CONCLUSION

Asthma, NO2, Home remodeling history, Environment Tobacco Smoke(ETS), Pet exposure, Mould, and Age＜1 year are risk factors for chronic coughing in children. Due to the few studies and insufficient evidence, other potential risk factors need to be robustly confirmed by subsequent large-sample and multicenter trials.

Assessment of smoking in adolescents - a sample from vocational education centre

OBJECTIVE

The aim of this study was to analyse the knowledge and attitudes about smoking in young people between 16-20 years of age, who were both working and attending the Vocational Education Centre.

METHODS

This study was conducted with high school students at the Vocational Education Centre. The socio-demographic questionnaire and the Fagerström Test of Nicotine Dependence (FTND) were applied to the students using a face-to-face interview technique. Secondly, interactive educations on smoking-free life and smoking-related diseases were given. At last, CO (carbon monoxide) levels and respiratory functions were evaluated.

RESULTS

Of the students 92.9% were males, 37.4% were 16 years, 35.8% were 17 years and 26.9% were 18-20 years old. Among 46.9% of smokers, 75.8% started smoking before 15 years of age, 86.1% were living with smokers. While 70.5% of smokers smoked more than 10 cigarettes daily, 61.3% smoked their first cigarette in the first half hour after waking up. Of the smokers, 28.8% were highly dependent, 13.0% were very highly dependent. CO levels were significantly higher in those who smoked in the workplace, who smoked mostly in the morning time, and those who started smoking at 7 years of age and younger (p < 0.05). FEV1, FVC, FEF25-75 values of morning smokers were significantly lower (p < 0.05).

CONCLUSION

Unfortunately, the first smoking age was very low, the first cigarette of the day was lit in a short time after waking up, and family/friend's attitudes and behaviours were encouraging in this age group. More attention should be paid to this issue and especially new preventive projects should be implemented to protect young people from smoking.

Irritant-Induced Chronic Cough Triggers: A Scoping Review and Clinical Checklist

Purpose The primary aim of this review was to identify environmental irritants known to trigger chronic cough through the life span and develop a comprehensive clinically useful irritant checklist. Method A scoping review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews, checklist, and explanation. English-language, full-text resources were identified through Medline, PsycINFO, SPORTDiscus, Web of Science, and ProQuest Dissertations and Theses Global. Results A total of 1,072 sources were retrieved; of these, 109 were duplicates. Titles of abstracts of 963 articles were screened, with 295 selected for full-text review. Using the exclusion and inclusion criteria listed, 236 articles were considered eligible and 214 different triggers were identified. Triggers were identified from North America, Europe, Africa, Asia, and Australia. Occupational exposures were also delineated. Conclusions A clinically useful checklist of both frequently encountered triggers and idiosyncratic or rare triggers was developed. The clinical checklist provides a unique contribution to streamline and standardize clinical assessment of irritant-induced chronic cough. The international scope of this review extends the usefulness of the clinical checklist to clinicians on most continents.

Child labor in a rural Egyptian community: an epidemiological study

OBJECTIVES

Estimating the burden of child labor in a rural community of El-Minia governorate, Egypt and exploring its determinants and health impact.

METHODS

One hundred and ninety nine children randomly participated from a randomly selected village; 147 (73.9%) males and 52 (26.1%) females, whose ages ranged from 6 to 17 years (mean age 12.1 ± 2.9). All children were subjected to interview questionnaire, and medical examination.

RESULTS

Ninety (45.2%) of the children reported that they are engaged in a work. The working children belonged to 65.6 and 85.6% of illiterate fathers and mothers, respectively. The majority of the working children were engaged in jobs at quarries (58.9%), followed by farming (21.1%), then small proportions of children were working in other jobs. Poverty, big families and insufficient family's income were the most frequently reported reasons for starting to work (80%). There was a significant higher prevalence of the reported health complaints among working children.

CONCLUSIONS

Working children are at high risk of many health problems. Poverty, parents' illiteracy, large family size and fathers' absence are the driving force for child labor in the rural community of Eastern Minia.
