Air Pollution Raises Respiratory Disease Risks for Children, Indonesian Study Finds
Children exposed to polluted air face significantly higher risks of respiratory diseases, according to new research published in 2026 by researchers from Poltekkes Kemenkes Yogyakarta. The study, led by Choirul Amri alongside Siti Hani Istiqomah, Iswanto, and Abdul Hadi Kadarusno, found that exposure to pollutants such as PM2.5, PM10, nitrogen dioxide, sulfur dioxide, and carbon monoxide contributes directly to respiratory illnesses including asthma, bronchitis, and acute respiratory infections in children.
Published in the International Journal of Natural and Health Sciences, the research highlights air pollution as one of the most urgent environmental public health threats affecting children worldwide. The findings are particularly relevant for rapidly urbanizing countries such as Indonesia, where growing traffic congestion, industrial activity, and fossil fuel use continue to reduce air quality in major cities and residential areas.
Why Air Pollution Has Become a Major Public Health Concern
Air pollution has emerged as a global environmental issue linked to rising rates of disease and declining quality of life. Urban expansion and industrial growth have increased the concentration of harmful pollutants in the atmosphere, especially in densely populated cities.
According to the researchers, children are among the most vulnerable groups because their lungs and immune systems are still developing. Children also breathe more rapidly than adults and often spend more time outdoors, increasing their exposure to contaminated air.
The study explains that polluted air can irritate the respiratory tract, trigger inflammation, damage lung tissue, and weaken immune defenses. Fine particulate matter, particularly PM2.5, is considered especially dangerous because it can penetrate deep into the lungs and even enter the bloodstream.
The researchers noted that poor environmental conditions are increasingly associated with long-term health burdens, including chronic respiratory diseases and reduced lung capacity later in life.
Literature Review Examined Global Research Over the Past Decade
The Indonesian research team conducted a descriptive-analytical literature review using scientific studies published during the past 10 years. Data were collected from major academic databases including Google Scholar, PubMed, and ScienceDirect.
The review focused on peer-reviewed articles examining the relationship between air pollution and respiratory health in children. The researchers analyzed studies discussing key pollutants, exposure levels, disease prevalence, and environmental risk factors.
By comparing findings from multiple countries and research settings, the team identified consistent global patterns linking deteriorating air quality with worsening respiratory outcomes in children.
Key Findings From the Study
The review found strong evidence connecting air pollution exposure with increased respiratory disease risks in children.
Major pollutants identified
The study highlighted several pollutants most strongly associated with respiratory problems:
- PM2.5 and PM10 particulate matter
- Nitrogen dioxide (NO₂)
- Sulfur dioxide (SO₂)
- Carbon monoxide (CO)
Among these pollutants, PM2.5 showed the most severe health effects because the microscopic particles can travel deep into lung tissue.
Diseases most commonly linked to pollution
Researchers found that children exposed to polluted air experienced higher rates of:
- Acute respiratory infections (ARI)
- Asthma
- Bronchitis
- Chronic coughing
- Wheezing and shortness of breath
Children living near highways, industrial areas, or densely populated urban neighborhoods faced greater exposure risks.
Long-term health impacts
The study also identified long-term consequences of prolonged exposure to polluted air. Children exposed to pollution over many years may experience:
- Reduced lung growth
- Permanent decreases in lung function
- Increased risk of chronic respiratory disease in adulthood
- Greater sensitivity to allergens and infections
The researchers emphasized that these impacts are not temporary and may continue throughout adulthood.
Socioeconomic Conditions Also Increase Vulnerability
The review found that air pollution affects disadvantaged families more severely. Children from low-income households often live in areas with poorer air quality and have limited access to healthcare, nutrition, and clean living environments.
Indoor pollution also emerged as a major concern. Exposure to cigarette smoke, poor ventilation, and household pollutants can worsen respiratory conditions already triggered by outdoor pollution.
The researchers explained that combined exposure to both indoor and outdoor pollution significantly increases health risks for children.
Environmental Policies and Public Awareness Are Critical
The study calls for stronger environmental public health policies to reduce pollution exposure and protect children’s health.
Recommended actions include:
- Stricter vehicle and industrial emission controls
- Expansion of green open spaces in urban areas
- Promotion of cleaner energy sources
- Improved public transportation systems
- Community education about pollution risks
- Encouraging parents to reduce children’s outdoor activities during poor air quality conditions
The researchers stressed that protecting children from air pollution requires collaboration between governments, healthcare providers, schools, communities, and industry.
In an academic conclusion, the authors from Poltekkes Kemenkes Yogyakarta stated that air pollution has become “an important determinant of children's respiratory health,” requiring “a comprehensive, integrated, and sustainable approach” to reduce long-term health risks for future generations.
Growing Global Attention on Children and Air Quality
The findings align with broader international concern about the health effects of environmental pollution. Studies from Asia, Europe, and North America have increasingly shown that childhood exposure to polluted air contributes to rising respiratory illness rates.
Global health experts warn that climate change, urbanization, and industrial emissions could worsen air quality in many regions over the coming decades unless stronger environmental protections are implemented.
For Indonesia and other developing countries, the research adds urgency to discussions surrounding sustainable urban planning, transportation reform, and public health protection.
The study also reinforces the idea that environmental quality is directly connected to long-term national health outcomes, particularly for younger generations who face cumulative exposure risks from an early age.
