PINCHE's policy recommendations on noise: how to prevent noise from adversely affecting children.

BACKGROUND: Noise can have auditory and non-auditory effects on children. Very few noise episodes affect children's hearing instantaneously; most effects are long-term and cumulative. Describing the risks of noise on children's health and well-being in a life-course perspective can illustrate the prospects of cumulative effects. CONCLUSION: The policy recommendations the Policy Interpretation Network on Children's Health and Environment (PINCHE) prepared for each age group or setting are described here.

Policy and science in children's health and environment: recommendations from the PINCHE project.

BACKGROUND: Policy recommendations result from the discussions and analysis of the present situation in environment and health. Such analysis was performed in PINCHE. This led to recommendations based on the scientific literature. In the field of children's environmental health the policy process will follow more or less fixed rules, but this process is still at an early level of development. The link between science and policy still faces many challenges. Scientific assessment of environmental risk must recognize and tackle the problems of data sets, variability of human and environmental systems, the range, spatial and temporal diffusion of potential health effects and many biases and confounding factors. RESULTS: The PINCHE network recommends a general improvement of the supporting scientific fields in environment and health. Assessments from epidemiology or toxicology should play a key role in influencing science-policy decisions in programmes that are intended to inform the public policy process. Scientific committees at a local level could play a role. The relation between health and environment needs to be better incorporated in training and education. There is a need for harmonization of data production and use. The priorities in PINCHE focus on the most important issues. A classification of low, medium or high priority for action was used to describe a range of different environmental stressors. CONCLUSIONS: PINCHE provided recommendations to reduce exposure for children. Exposure reduction is not always linked to improved health in the short term, but it will reduce the body burden of accumulating chemicals in children. A strategic choice is reduction of exposure of children to compounds by changing production techniques or by increasing the distance of child specific settings to sources. The contribution of all players in the production, distribution and use of scientific knowledge in the field of children's environmental health is necessary.

Today's epidemics in children: possible relations to environmental pollution and suggested preventive measures.

BACKGROUND: Facts and hypotheses on the relationship between some children's diseases or disorders and external stressors during the developmental stage of a child, both prenatally and postnatally are described in literature. In this paper the following changes in patterns and causes of the main childhood illnesses are summarized and recommendations for actions are made. Prematurity. Intra-uterine growth restriction. Testicular dysgenesis syndrome. Type I and Type II diabetes. Asthma, atopy and hay fever. Autism. Attention deficit hyperactivity disorder (ADHD). Learning disabilities. Cancer. Obesity. Hearing problems. RESULTS: Literature provides a growing amount of information on changing patterns in childhood diseases. CONCLUSIONS: The following recommendations for action are formulated: Immediate research on endocrine disrupters in relation to prematurity. Diabetes: avoid Maillard Compounds in liquid baby food and in food in general: promote breastfeeding. Asthma: avoid exposure to smoking, the use of chemical household products, dioxin and dioxin-like chemicals, and avoid air pollution with high levels of particulate matter, especially around conception, during pregnancy and in the first years of life. Autism: more research on incidence and causes. ADHD and learning disabilities: more research on prevalence and causes. Preventions: 1) preconception counselling to avoid potentially harmful substances; 2) controlling and further lowering levels of polychlorinated biphenyls, lead and methyl mercury. Cancer: promote breastfeeding, carry out research into effects of foetal exposure to internal fission-product radionuclides. Obesity: stop smoking in pregnancy, avoid parental obesity, longer night sleep. Hearing problems: lower noise levels in discothèques, promote the day-evening-night level to avoid noise (longer night sleep).
