Exploration of parental smokers' experience, perceptions, and family's influences on their smoking in the presence of children

Helicobacter pylori seropositivity protects against childhood asthma and inversely correlates to its clinical and functional severity

BACKGROUND

In recent years, the prevalence of asthma has risen in developed countries, and its extent related to a change in our indigenous microbiota. Helicobacter pylori disappearance across the population represents a fundamental change in our human microbiota and has preceded the rise in asthma prevalence.

OBJECTIVE

To assess the relationship between childhood asthma and Helicobacter pylori infection.

METHODS

Quantitative determination of Helicobacter pylori IgG among 90 asthmatic children and 90 - age and gender - matched non-atopic, non-asthmatic healthy children was performed using ELISA in serum of all participants.

RESULTS

Helicobacter pylori IgG seropositivity was found in 25.6% of asthmatics compared to 44.4% of controls. Asthmatics showed lower median Helicobacter pylori IgG titre compared to healthy controls. We also detected a significant inverse relationship between Helicobacter pylori IgG titre and asthma severity.

CONCLUSION

Helicobacter pylori seropositivity protects against childhood asthma and inversely correlates to its clinical and functional severity.

Effects of a Parent-Child Interactive Program for Families on Reducing the Exposure of School-Aged Children to Household Smoking

INTRODUCTION

Parental smoking has been identified as the major source of children's exposure to environmental tobacco smoke (ETS). Therefore, parental involvement is critical in ETS exposure prevention programs. This study examined the effects of a parent-child interactive program on reducing children's exposure to ETS at home and enhancing parents' and children's prevention strategies.

METHODS

A clustered randomized controlled trial was administered to 75 families of school-aged children from six primary schools in New Taipei City, Taiwan. Families in the intervention group received a parent-child interactive intervention, and parents in the control group received written materials on tobacco hazards. Data on children's exposure and the prevention of children's exposure to ETS at home were obtained at baseline, 8-week, and 20-week or 6-month assessments.

RESULTS

The percentage of children with urine cotinine levels greater than or equal to 6 ng/ml was significantly lower in the intervention group than it was in the control group at both the 8-week and 6-month assessments. The intervention significantly reduced parental smoking in the presence of children and increased parents' prevention of children's ETS exposure and children's ETS avoidance behavior from the baseline to the 20-week assessment.

CONCLUSIONS

This is a preliminary study design aimed at creating a program for reducing children's ETS exposure at home. Further research to produce evidence supporting the application of the parent-child interactive program in primary schools is suggested. The theoretical basis of the intervention design can serve as a reference for nursing education and the design of health education programs.

Factors associated with parental smoking in the presence of school-aged children: a cross-sectional study

Background

In 2009, the Tobacco Hazards Prevention Act (Taiwan) was amended to more effectively restrict smoking in indoor public places and workplaces in Taiwan. However, the lack of prohibitions for smoking in private homes may place family members at increased risk for exposure to environmental tobacco smoke (ETS). The aim of our study was to determine the factors associated with parental smoking in the presence of children at home.

Methods

In 2010, we performed a cross-sectional study of factors associated with parental smoking in the presence of children at home in Taiwan using self-administered questionnaires. Quota sampling was used to select five primary schools from four different regions of Taiwan. Parents were surveyed to identify parental smokers and 307 parental smokers were selected for participation in our study. Questionnaire data regarding parental smoking in the presence of children at home and related interactions among family members were analyzed. Hierarchical logistic regression was used to determine the best-fit model for examining the relationships among the variables related to parental smoking in the presence of children at home.

Results

Two-thirds of parents who smoked reported smoking in the presence of their children. The results of the hierarchical logistic regression analysis identified the smokers’ compliance with their family’s antismoking responses, mutual agreement with smoking bans, daily smoking, smoking more than 20 cigarettes per day, the education level of the parental smoker, and the annual family income as determinants of smoking in the presence of children at home.

Conclusions

Households with smoking parents should be targeted for interventions to encourage the adoption and enforcement of home smoking bans. Educational interventions that promote smoke-free homes for children and provide support to help parents stop smoking are critical factors in reducing the frequency of children’s ETS exposure in the home.
