In the context of climate change and child health, the present study was designed to determine the current information status and suitable information channels for parents. The majority of respondents say they know where to find information about climate change and health, while it was also shown that half of the participants do not feel well informed. Currently, parents from our sample primarily seek information via the internet and social media, newspapers, and books or magazines. It was not evaluated in detail which webpages they use. Parents' sense of uninformedness raises the question of whether the information sources already being used are actually appropriate, or whether there are other mediators that would be more suitable for educating parents. Health care professionals are highly trusted by the German population and can therefore play a valuable role in combating the challenges of climate change for society [18]. Nevertheless, our results show that only a small portion of our studied sample of parents considers pediatricians or general practitioners as suitable sources of information. As stated in a policy statement by the American Academy of Pediatrics (AAP) [19], it is possible to identify pediatricians as an important and underutilized resource for providing climate change and health education. Pediatricians should broaden and strengthen their knowledge about the health consequences of climate change to realize and oppose them. By understanding the threats of climate change on child health, pediatricians can engage in informing parents and seek their awareness to become a suitable and trustworthy information source for parents [19]. Although our study results address only a very specific subset of parents and are therefore difficult to generalize, it is undisputed that failure to act will lead to major injustices for the next generations [20]. Parents of all sociodemographic groups have regular contact with their pediatricians in Germany. We assume that this is precisely why they are a suitable source to address the groups unable to be reached by the survey, due to differing interest in the topic. Therefore, we recommend that pediatricians engage more in proactively communicating and mitigating the health impacts of climate change. One approach would be to reinforce their education through training modules, such as those drafted and offered by the LMU Munich [21][22].
Furthermore, we wanted to investigate how parents perceive the relevance of health risks posed to their children through climate change. The consequences of climate change were seen as having varying extents of relevance to child health, but for almost all participants, climate change and health is already a relevant topic. The most relevant health risk for their children was seen in increasing air pollutants, followed by changes of UV-radiation. Mental and physical consequences because of extreme weather events were seen less frequent as a risk. The assessment could be different due to the flood events in Rhineland-Palatinate (Germany), which occurred after the survey was conducted. This is somewhat different to results of a representative German population survey [23] which showed that participants were especially worried about more frequent occurrence of heat waves, drought, and forest fires. Equally worrying were more frequent storms and floods [23]. The results could differ because of the restriction of our study to analyze parents mainly from cities, where air pollution is more present. We could show that participants feel worried by climate change and its consequences. When asked about risks due to climate change, only 14.1% of all German participants named health consequences [23]. For over a half (51.7%), natural disasters and weather problems were perceived as risks. When asked about the specific health consequences due to climate change, on average participants felt worried [23]. A study conducted in the United States [24] came up with similar results compared to the one just introduced [23]; open questions in particular showed missing associations about climate change and consequences for human health [24]. This result may be explained by the fact that media articles only seldom cover the topic of climate change and human health [1]. Over a ten-year period (2008-2018), the newspaper the People’s Daily published, on average, about 2500 articles each year addressing climate change, from which only 14 articles a year also focused on human health [1]. Mass media might in some cases have an impact on a person’s risk perception, whereas interpersonal communication channels may be effective as well [25].
In our study we asked about the risk for the own child compared to other children at the same age and found that parents generally perceived a risk for their child that was as high as that for other children the same age. Since risk perception is a relevant predictor for changing or adapting behavior [13], we wanted to examine the antecedence for risk perception of parents and analyzed the effect of knowledge and relevance estimation. We differentiated between general and individual risk perception and gained similar results for both types. It has been suggested that knowledge has an impact on risk perception, but this does not appear to be the case. The results presented in the conducted study show that knowledge alone does not seem to predict risk perception. On the other hand, relevance estimation has a statistically significant effect on risk perception. It can therefore be assumed that a person will rather bring up intentions for individual behaviorial- and preventive actions in the context of climate change and health when relevance for the own child’s health is recognized. The results suggest that it is not sufficient to only provide information or knowledge about climate change and health consequences; the relevance for the own child should also be demonstrated and linked with experiences of the parents that already happen or could happen in future. Risk perception and—in a second step—intentions towards preventive actions could in that way be supported.
Limitations and further research
The results of the conducted study reflect only a small number of well-educated parents from a convenience sample. Therefore, many demographic groups are left out and generalizability is difficult. Assuming a lower level of information and awareness in other demographic parent groups, our study aims to overcome this gap by involving pediatricians more often and effectively.
Further research should be undertaken to identify possibilities for pediatricians to implement formats for informing parents about the expectable consequences, since it is a problem that is not going to disappear or become weaker. It should be discovered if more parents can be reached through pediatricians, and in what way their knowledge, relevance estimation, and risk perception changes when using a medical and trustworthy source rather than the internet as primary source.
