Since February 2011, we have started to invite all of the participants of the RECORD Study to a second health examination and to a second survey wave.
Coordinated by Inserm and by University Pierre et Marie Curie, the second study wave is conducted in collaboration with the Centre d’Investigations Préventives et Cliniques and the University of Montreal.
We have already interviewed and examined 880 participants.
Based on a second measurement of cardiovascular risk factors 4 or 5 years after the baseline measures, we will investigate the extent to which social characteristics of participants and the multiple characteristics of their residential neighborhoods are associated with changes in the cardiovascular risk profile over time.
Moreover, the second wave of the study is particularly interested in mobility, and geocodes a number of activity places to which people regularly go. These data should allow us to incorporate patterns of mobility and “spatial behavior” in the investigation of the effects of the environments on health.
UMR-S 707 is involved in a comprehensive work related to the health of the population of Paris coordinated by the Ile-de-France Regional Health Observatory for the Health Department of the City of Paris.
Analyses of the data collected for 2128 participants residing in Paris in the context of the RECORD Study will provide additional information related to the health of the population of Paris.
We thank the Health Department of the City of Paris, and particularly Ghislaine Grosset.
We are preparing the second RECORD Study wave. In this context, about 7250 participants will be invited to a second health examination.
Epidemiologic research relies to a large extent on "cohort studies" in which a number of participants are surveyed and examined at a given point in time and followed over time. Cohort studies are based on the idea that to examine if a specific exposure (e.g., an environmental one) is related to a given health problem, it is relevant to measure the exposure at a certain moment in time and assess whether the exposure leads to the incidence of the health problem in the follow-up period among people who were free of this health condition at the beginning of the study. In other words, epidemiologic studies often need data collected at different points in time (i.e., longitudinal data) to attempt to identify causes of health problems.
Inviting the participants to a second health examination will allow us to obtain a second measures of a number of clinical and biological risk factors of cardiovascular diseases that are of particular interest to us (weight and waist circumference, blood pressure, cholesterol, etc.). Based on these data, we will be able to investigate changes in these metabolic parameters over a 5 year period and the social and environmental exposures that are associated with the incidence of metabolic conditions over the follow-up.
In this second study wave, survey questionnaires and different assessment tools will be used to better understand the relationships that exist between geographic life environments and cardiovascular health.
