I am looking for a concise review of published literature - or relevant papers/reports - particularly any recent (i.e. last 6 years) results - on health care utilization (formal or informal), social networks (e.g.Prof Lisa Berkman's approach to constructing social networks) and ageing and older adult populations. See for example: Berkman L, Sekher TV, Capistrant B, Zheng Y. “Social networks, family, and care giving among older adults in India”. In: Smith JP, Majmundar M (eds.). Aging in Asia: Findings from New and Emerging Data Initiatives. Committee on Population, Division of Behavioral and Social Sciences and Education. Washington, DC: The National Academies Press, 2012.
