Environmental health policies for women's, children's and adolescents' health.

Abstract

Environmental health risks especially affect women and children, because they are more vulnerable socially and because exposures to environmental contaminants create greater risks for children's developing bodies and cognitive functions. According to the 2016 World Health Organization (WHO) estimates, modifiable environmental risk factors cause about 1.7 million deaths in children younger than five years and 12.6 million total deaths every year. (1) Although the Global strategy for women's, children's and adolescents' health (2016-2030) (2) was launched during the United Nations Sustainable Development Summit 2015, governments rarely recognize the sustainable development agenda as a transformative factor for health. The sustainable development goals (SDGs) offer opportunities for countries to create healthier environments for women, children and adolescents. This paper explores how the SDGs can be used to reduce environmental health risks and enhance the health of women, children and adolescents. In particular, we focus on drivers for urbanization and sustainable development (e.g. transport, housing, urban design and energy provision) that can advance the global strategy, but have not traditionally been a focus of health policy-making. We frame the discussion around the three pillars of the global strategy: survive, thrive and transform, while recognizing the inevitable overlap between these objectives. Survive Since women and children are especially affected by the environment, intersectoral interventions that reduce environmental risks will improve early childhood survival as well as reducing risks of premature death throughout the life-course. For instance, household air pollution from dirty fuels and inefficient cookstove was estimated to have caused around 4 million premature deaths in 2012 and was responsible for more than half of deaths due to childhood pneumonia. (3) Among women, indoor exposures to household cookstove smoke were estimated to cause 34% (452 548/1336601) of chronic obstructive pulmonary disease deaths, 21% (732 937/3 476 815) of stroke deaths, 19% (93 537/489 390) of lung cancer deaths and 14% (479478/3425 835) of ischaemic heart disease deaths in 2012. (4,5) Improving access to reliable electricity and clean water in health-care facilities can also help reduce maternal and newborn mortality, as such infrastructure is a critical determinant of quality of care. (6) A review of health-care facilities in 11 sub-Saharan African countries showed that an average of 26% of facilities had no electricity whatsoever. (7) Another review of 54 low- and middle-income countries found that 38% (25 118/66 101) of health facilities lack a clean drinking water source. (8) Ensuring that health-care facilities have access to power and water is a minimum requirement for attracting women to facilities and guaranteeing quality services for safe childbirth. Thrive Housing and energy sector interventions that promote the transition to cleaner fuels and for domestic cooking, heating and lighting can not only reduce deaths but improve the health of the 3 billion people worldwide who are reliant upon inefficient and polluting cookstoves. For this reason, the monitoring framework of the Global strategy for women's, children's and adolescents' health (2016-2030) explicitly tracks an indicator for primary reliance on clean fuels and technologies in households as part of its thrive pillar. (9) Examples of cleaner fuels and include liquefied petroleum gas, biogas, ethanol and electricity including photovoltaic solar-power for lighting. Improving access to clean fuels and can also reduce the burden of childhood burns and poisonings due to the use of kerosene for cooking and lighting. While most of the estimated 3 million deaths annually from outdoor ambient air pollution are among adult populations, reducing such pollution exposures are also critical to improving children's health and development across the life-course. …
