Using the health beliefs model to explore children's attitudes and beliefs on air pollution

Wearing masks as a protective measure for children against traffic-related air pollution: A comparison of perceptions between school children and their caregivers in Ho Chi Minh City, Vietnam

BACKGROUND

Traffic-related air pollution (TRAP) problems are unlikely to be solved in the short term, making it imperative to educate children on protective measures to mitigate the negative impact on their health. Children and their caregivers may hold differing views on wearing a face mask as a safeguard against air pollution. While many studies have focused on predicting children's health-protective behaviours against air pollution, few have explored the differences in perceptions between children and their caregivers.

OBJECTIVES

To examine this, we conducted a study that compared the health beliefs of two generations and evaluated the factors that influence the use of masks by children to reduce air pollution exposure.

METHODS

The study was conducted in 24 secondary schools and involved 8420 children aged 13-14 and their caregivers. We used a Health Belief Model (HBM)-based instrument containing 17-item self-administered health beliefs questionnaires to gather data. The results were analysed using hierarchical logistic regression to determine the probability of children frequently wearing masks to protect against TRAP.

RESULTS

Our study showed both children and caregivers recognised that several factors could influence mask-wearing among children: discomfort or difficulty breathing while wearing a mask and forgetting to bring a mask when going outside; perceived threats of the poor quality of air and children's respiratory health problems; and cues to mask use (i.e., seeing most of their friends wearing facemasks and ease of finding masks in local stores). However, only children were significantly concerned with public perception of their appearance while wearing a mask. Females were more likely to wear masks, and caregivers with higher levels of education were more likely to encourage their children to wear masks. Children who commuted to schools by walking, biking, or motorbiking were also more accepting of mask-wearing than those who travelled by car or bus.

CONCLUSIONS

Children and their caregivers hold different perceptions of wearing masks to protect against air pollution. Children are more susceptible to social judgements regarding their appearance when wearing a mask.

Observation of covid-19 safety protocols by persons with chronic health conditions in Ghana: The influence of health belief model

Covid-19 has brought distortion to health delivery globally and made it challenging to seek healthcare, but persons with chronic health conditions who require continuous medical attention have suffered the most as all attention at the medical front was directed to covid-19 related issues. The study explores how the five primary constructs of the health belief model were used to drive adherence to covid-19 preventive protocols among persons with chronic health conditions in Ghana. A quantitative technique was used for data collection and analyses. SPSS version 21 and AMOS version 21 were used to analyze data. Hierarchical regression from SPSS were used to examine the influences of health belief model constructs on chronic patients' adherence to covid-19 preventive protocols. The study's finding indicates that perceived susceptibility, severity, and self-efficacy influence adherence to covid-19 protocols among persons with chronic conditions. While perceived benefits and perceived barriers though they have negative and positive influences on adherence, they were not statistically significant. Perceived self-efficacy has a negative influence on the perceived barrier and a positive influence on perceived benefit. Gender has positive influence on Perceived susceptibility. The study's outcome indicated that persons with chronic health conditions need special arrangements to ease their access to healthcare during outbreaks. Hence, public health professionals need to educate chronic patients on how to practice the covid-19 preventive protocols and support them with covid-19 preventive materials to increase their self-efficacy to adhere to covid-19 protocols.

Burden of asthma-like symptoms and a lack of recognition of asthma in Vietnamese children

OBJECTIVE

Lack of recognition of asthma in childhood results in unmet asthma treatment needs and leads to the risk of sub-optimal respiratory health. The present study assessed the prevalence of asthmatic under-recognition in middle school children in Vietnam.

METHODS

We conducted a school-based survey among 15,112 Vietnamese children. Most of them are aged from 13 to 14. Schools and students were recruited using multi-stage sampling. Respiratory symptoms were collected via self-report using a standardized tool from the International Study of Asthma and Allergies in Childhood. Under-recognition of asthma was defined as a presence of at least one asthma-like symptom but a negative response to having ever asthma. Associations were investigated using logistic regression.

RESULTS

Prevalence of asthma-like symptoms was 27.3% and prevalence of physician-diagnosed asthma was 8.5%. Over 80% of symptomatic children were not diagnosed with asthma. Under-recognition of asthma was found more in girls (adjusted odds ratio; aOR = 1.75; 95%CI: 1.54 to 1.98).

CONCLUSIONS

Asthma is significantly under-recognized in Vietnamese middle-school children. Urgent action is required to improve the recognition of asthma in Vietnam.
