Summary

Unblinded randomized clinical superiority trial in two parallel groups (intervention vs. no intervention) national multicentre to evaluate the effectiveness of the platforms on the evolution of phenoxyacetic acid levels measured in the urine at inclusion and 3 months after the intervention for patients who received the intervention compared to patients who did not receive the intervention.

Detailed description

it is now recognized that there is a link between certain environmental exposures (occupational and extra-occupational) and reproductive pathologies. During pregnancy, environmental exposures are associated with an increased risk of spontaneous miscarriage, congenital malformations, certain adverse outcomes (fetal death in utero, intrauterine growth retardation, prematurity) and could also increase the risk of chronic disease in childhood and adulthood (hypothesis of developmental origins of health and disease), and have transgenerational effects. Intervention studies have shown efficacy in reducing exposures to certain chemicals, particularly by reducing exposure to cosmetics. In the scientific literature, a pre-conception visit is recommended to identify environmental exposures. In France, platforms are dedicated to the evaluation of environmental exposures in patients with fertility disorders and pregnancy-related pathologies and provide support for the implementation of targeted prevention actions. The intervention is taken care of by the PREVENIR platforms. This care consists of a consultation carried out by an environmental health expert (midwife, environmental health engineer) from the PREVENIR platforms. This consultation is carried out through a protocolized interview already developed which allows the identification of exposure to risk factors on reproduction. During the interview, prevention messages targeted at the exposures identified during the interview are delivered.
