[Health and the city: physical health and mental health].
In France, city size has very little bearing on the mortality rate as a function of age and life expectancy and it is in large cities that these indicators are the most favorable. No increase in maternal or infant mortality rates or deaths due to cancers has been observed in large cities. The lower mortality rate linked to respiratory and cardiovascular diseases in large urban areas contradicts the fears concerning the impact of air pollution. Deaths linked to lifestyle are less frequent in big cities, which could be due to social structures (socio-professional level: the proportion of white-collar workers and professionals is higher in bigger cities than in the suburbs or small cities). However, although the overall mortality rate is lower, it should be emphasized that there is in large cities a greater incidence of sexually transmitted diseases, AIDS and certain infectious diseases (because of social diversity and the fact that certain individuals seeking anonymity and marginality are drawn to large cities). In terms of mental health, the breakdown of family structures, instability, unemployment, the lack of parental authority and failing schools render adolescents vulnerable and hinder their social integration. When the proportion of adolescents at risk is high in a neighborhood, individual problems are amplified and social problems result. In order to restore mental and social health to these neighborhoods, ambitious strategies are necessary which take into account family and social factors as well as environmental ones. At the present time, when physical health is constantly improving, the most pressing problems are those related to lifestyle and mental health which depend for a large part on social factors.
