A quarter of all global deaths of children under five are due to unhealthy or polluted environments including dirty water and air, second-hand smoke and a lack or adequate hygiene, the World Health Organization (WHO) said on Monday.
Such unsanitary and polluted environments can lead to fatal cases of diarrhoea, malaria and pneumonia, the WHO said in a report, and kill 1.7 million children a year.
“A polluted environment is a deadly one -– particularly for young children,” WHO Director-General Margaret Chan said in a statement. “Their developing organs and immune systems, and smaller bodies and airways, make them especially vulnerable to dirty air and water.”
In the report — “Inheriting a sustainable world: Atlas on children’s health and the environment” — the WHO said harmful exposure can start in the womb, and then continue if infants and toddlers are exposed to indoor and outdoor air pollution and second-hand smoke.
The WHO said that every year:
- 570 000 children under 5 years die from respiratory infections, such as pneumonia, attributable to indoor and outdoor air pollution, and second-hand smoke.
- 361 000 children under 5 years die due to diarrhoea, as a result of poor access to clean water, sanitation, and hygiene.
- 270 000 children die during their first month of life from conditions, including prematurity, which could be prevented through access to clean water, sanitation, and hygiene in health facilities as well as reducing air pollution.
- 200 000 deaths of children under 5 years from malaria could be prevented through environmental actions, such as reducing breeding sites of mosquitoes or covering drinking-water storage.
- 200 000 children under 5 years die from unintentional injuries attributable to the environment, such as poisoning, falls, and drowning.
The report also noted that in households without access to safe water and sanitation, or that are polluted with smoke from unclean fuels such as coal or dung for cooking and heating, children are at higher risk of diarrhoea and pneumonia.
Children are also exposed to harmful chemicals through food, water, air and products around them, it said.
Maria Neira, a WHO expert on public health, said this was a heavy toll, both in terms of deaths and long-term illness and disease rates. She urged governments to do more to make all places safe for children.
“Investing in the removal of environmental risks to health, such as improving water quality or using cleaner fuels, will result in massive health benefits,” she said.
The WHO urged governments to work on developing:
- Housing: Ensure clean fuel for heating and cooking, no mould or pests, and remove unsafe building materials and lead paint.
- Schools: Provide safe sanitation and hygiene, free of noise, pollution, and promote good nutrition.
- Health facilities: Ensure safe water, sanitation and hygiene, and reliable electricity.
- Urban planning: Create more green spaces, safe walking and cycling paths.
- Transport: Reduce emissions and increase public transport.
- Agriculture: Reduce the use of hazardous pesticides and no child labour.
- Industry: Manage hazardous waste and reduce the use of harmful chemicals.
- Health sector: Monitor health outcomes and educate about environmental health effects and prevention.
