Implementing a context-driven awareness programme addressing household air pollution and tobacco: a FRESH AIR study

eHealth literacy in the general population: a cross-sectional study in China

BACKGROUND

eHealth literacy (eHL) is positively associated with health-related behaviors and outcomes. Previous eHL studies primarily collected data from online users and seldom focused on the general population in low- and middle-income countries (LMIC). Additionally, knowledge about factors that affect eHL is limited. Chronic lung disease (CLD) has brought a large burden in LMIC, making it a relevant example for studying eHL. This study aims to explore eHL and its associated factors within the general population of China, encompassing sociodemographic characteristics, CLD knowledge, digital access, eHealth use and attitudes towards eHealth.

METHOD

Data were collected from November 2023 to January 2024 via online and hard-copy questionnaires among the general population in China. Descriptive analyses were performed to explore eHL, CLD knowledge, digital access, and attitudes towards eHealth at different sociodemographic levels. Univariable and multivariable regression analyses were performed to identify factors associated with eHL.

RESULTS

439 valid questionnaires were collected. Participants demonstrated a mean eHL of 24.7 ± 8.2 and CLD knowledge of 5.9 ± 3.7, obtained a score of 6.9 ± 1.8 in attitudes towards eHealth. A notable percentage of participants (45/439, 10.3%) reported no digital access, especially those aged 66+, the unemployed, retired, those with a primary school or below degree and earning ≤ 1500 RMB monthly. Multivariable hierarchical regression analysis showed higher eHL was uniquely associated with younger age (b=-0.10, P < .001), higher educational level (b = 2.02, P < .001), higher income (b = 1.10, P < .001), having digital access (b = 6.35, P < .001), more frequent eHealth use (b = 1.14, P < .001), and more positive attitudes towards eHealth (b = 0.47, P = .003).

CONCLUSION

Our sample from the general population in China had a relatively low eHL and CLD knowledge level, but held a positive attitudes towards eHealth. A digital divide was noticed between the elderly, low socioeconomic population and other groups. Younger age, higher educational and income level, having digital access, more frequent eHealth use and more positive attitudes towards eHealth were significantly associated with higher eHL. Efforts at both individual and systematic levels should be made to improve eHL, and promote CLD knowledge and digital access, especially in disadvantaged populations. Moreover, there is a pressing need to develop and refine national and international standards for eHL.

Issue 2 - "Update on adverse respiratory effects of indoor air pollution". Part 2): Indoor air pollution and respiratory diseases: Perspectives from Italy and some other GARD countries

OBJECTIVE

to synthesize the Italian epidemiological contribution to knowledge on indoor pollution respiratory impact, and to analyze the perspective of some GARD countries on the health effects of indoor air pollution.

RESULTS

Italian epidemiological analytical studies confirmed a strong relationship between indoor air pollution and health in general population. Environmental tobacco smoke, biomass (wood/coal) fuel for cooking/heating and indoor allergens (house dust mites, cat and dog dander, mold/damp) are the most relevant indoor pollution sources and are related to respiratory and allergic symptoms/diseases in Italy and in other GARD countries such as Mexico, Brazil, Vietnam, India, Nepal and Kyrgyzstan. Community-based global health collaborations are working to improve prevention, diagnosis and care of respiratory diseases around the world, specially in low- and middle-income countries, through research and education.

CONCLUSIONS

in the last thirty years, the scientific evidence produced on respiratory health effects of indoor air pollution has been extensive, but the necessity to empower the synergies between scientific community and local administrations remains a challenge to address in order to implement effective interventions. Based on abundant evidence of indoor pollution health effect, WHO, scientific societies, patient organizations and other members of the health community should work together to pursue the GARD vision of "a world where all people breathe freely" and encourage policy makers to increase their engagement in advocacy for clean air.

Understanding the Risk Factors, Burden, and Interventions for Chronic Respiratory Diseases in Low- and Middle-Income Countries: A Scoping Review

Objective

This scoping review aims to identify risk factors for COPD and asthma, examine the burden and intervention measures, and clarify the findings in the context of climate change, with a particular focus on LMICs.

Methods

Following the PRISMA-ScR guidelines, we conducted a scoping review using PubMed, Embase, and Scopus, focusing on studies published from 2011 to 2024.

Results

Our review included 52 studies that encompassed 244,004 participants. Predominantly conducted in SSA (n = 43, 83%) and Asia (n = 16, 31%), they address indoor and ambient air pollution, occupational hazards, and environmental conditions. Climate change exacerbates risks, varying regionally. SSA faces severe household and occupational exposures, while other LMICs deal with industrial and urban pollution. Stigma, social exclusion and economic burden underscore the necessity for intervention strategies (e.g., educational programs, pulmonary rehabilitation, low-emission cookstoves).

Conclusion

Our research shows a strong link between air pollution, occupational and environmental exposures, and the prevalence of COPD and asthma in LMICs. It suggests that targeted interventions are effective ways to mitigate these diseases and also highlights the significant impact of climate change on respiratory health.

Clinical Characteristics, Treatment Patterns and Economic Burden of COPD in Kyrgyzstan: A FRESH AIR Study

BACKGROUND

COPD prevalence and mortality in Kyrgyzstan are high. Data on clinical and economic impact of COPD in Kyrgyzstan are scarce. This study was part of the FRESH AIR research project that focused on prevention, diagnosis and treatment of chronic lung diseases in low-resource settings.

AIM

We aimed to evaluate the clinical characteristics, treatment patterns and economic burden of COPD in Kyrgyzstan.

METHODS

A representative sample of patients with a spirometry-confirmed diagnosis of COPD was included. All patients were registered in one of the five major hospitals in Kyrgyzstan. Patients were surveyed on COPD risk factors, health-care utilization and patient reported outcomes (CCQ, MRC). Associations with high symptom burden (MRC score ≥4) and cost were assessed using logistic regression analyses.

RESULTS

A total of 306 patients were included with mean age 62.1 (SD: 11.2), 61.4% being male, mean BMI 26.9 (SD: 5.2) and mean monthly income $85.1 (SD: 75.4). Biomass was used for heating and cooking by 71.2% and 52.0%. Current and ex-smokers accounted 14.1% and 32%. Mean FEV1 was 46% (SD: 12.8), 71.9% had COPD GOLD III-IV and most frequent co-morbidities were hypertension (25.2%), diabetes (5.6%) and heart diseases (4.6%). Mean CCQ score was 2.0 (SD: 0.9) and MRC score 3.7 (SD: 0.9). Yearly mean number of hospital days due to COPD was 10.1 (SD: 3.9). Total annual per-patient costs of reimbursed health-care utilization ($107) and co-payments ($224, ie, 22% of patients' annual income) were $331. We found that only GOLD IV and hypertension were significantly associated with high symptom burden. Exacerbations and hypertension were significantly associated with high cost.

CONCLUSION

The clinical and economic burden of COPD on patients and the government in Kyrgyzstan is considerable. Notably, almost half of interviewed patients were current or ex-smokers and biomass exposure was high.
