title: [Isolation, social support, life events and health status].
abstract: Research on the influence of social networks and social support on health status, conducted in English-speaking countries over the past decade, is not yet widespread in France. A review of the literature reveals that this social support has undeniable effects on mental health, and less obvious effects on physical health; it also stresses the major conceptual and methodological problems encountered in socio-epidemiological approaches. It would appear necessary to construct an overall model integrating life events, coping abilities and individual psychological factors; Social support is considered as a function of social networks, fulfilling roles of emotional support, material help, information provider, egostrengthener and social normalizer. Its mechanisms for dealing with stress, especially the buffer-role hypothesis, are also discussed.
