Environment and women's and children's health

"Climate change" refers to the variation of the Earth's climate, i.e. the set of variations in time and space of environmental and climatic parameters in their average values. The main environmental parameters are: temperatures, precipitation, ocean temperatures, distribution and development of plants and animals. Climate change and air pollution undermine and threaten everyone's health, but in particular that of the most vulnerable, such as pregnant women, babies and children.

According to data from the World Health Organization (WHO) campaign and the United Nations (UN) Agencies' Appeal ahead of the negotiations of the Global Conference of the Parties (COP28) on Climate Change held in Dubai in 2023, pregnant women, infants and children face significant risks to their health. Even an increase of just one degree Celsius is - in fact - problematic in pregnant women since her body has the task of protecting the baby from sudden changes in temperature. An eventual increase in temperature is more incisive, rather than a decrease. The child experiences problems due to his small body surface area and weight and because he has very little thermoregulation skills, also due to the immaturity of the sweat glands. The adverse effects that can be generated are: a preterm pregnancy, reduced growth of the baby during pregnancy, reduced weight of the newborn at birth, problems of hypertension or eclampsia in the woman. In children, exposure to higher temperatures can cause problems with thermoregulation, increased neonatal mortality, growth disorder, problems with adaptation for hydration and balance of mineral salts, and growth disorder that can continue as we age. When there is a problem of thermoregulation for both women and children, the indication is: cool down, do not go out during the hottest hours and dress appropriately. It should be remembered that as the temperature rises, so does an increase in ozone, which is a toxic gas.

According to the document entitled "Protecting maternal, newborn and child health from the impacts of climate change" by the ACP (Cultural Association of Paediatricians), the effects of climate events on maternal and child health have been neglected, and underestimated. Still very few countries mention maternal or child health in their climate change response plans.

Bruce Alward, Assistant Director-General for Universal Health Coverage Life Course at WHO, said: "Children's futures must be consciously protected, which means taking climate action now for the sake of their health and survival, while ensuring their special needs are recognised." Omar Abdi, Deputy Director of the United Nations Children's Fund, said: "Children's bodies and minds are particularly vulnerable to pollution, deadly diseases and extreme weather; it is a collective responsibility to listen to and put children at the centre of urgent climate action, starting with COP28. Now is the time to finally put children on the climate change agenda." Diene Keita, Deputy Executive Director for Programmes at UNPA, the UN Sexual and Reproductive Health Agency, said: "Global climate solutions must support and not sacrifice gender equality.

The Honourable Helen Clark, Chair of the PMNCH Board and former Prime Minister of New Zealand, said: "Climate change is one of the major intergenerational injustices of our time. Safeguarding the health of children and adolescents is non-negotiable in the face of the climate crisis."

All stakeholders, from governments to the private sector and civil society, including health professionals, play a critical role in advocating for policies and actions that protect the most vulnerable. The urgency of integrating the health of women, children and adolescents into studies on climate change and its consequences is not only a moral imperative, but an effective strategy with long-term benefits for resilient and healthy societies. The call to action was launched by WHO, UNICEF and UNFPA with the support of the Partnership for Maternal, Newborn and Child Health (PMNCH), the world's largest alliance for the health and well-being of women, children and adolescents, with more than 1,400 organizations. It is clear how important it is to combat climate change which, in the short term, could also mean simply starting to plant trees, increasing green areas.
