The INCLEN (International Clinical Epidemiological Network) is a unique international network of healthcare professionals (clinical epidemiologists, biostatisticians, health social scientists and other health professionals) who apply multidisciplinary approaches to identify best practices to improve ‘health for all’ in local, national, regional and global settings. It has established a surveillance site for studying the issues of chronic diseases with focus on childhood obesity near Delhi, in Palwal district of Haryana. Surrounded by three major roads (NH – 2, Palwal – Hathin Major District Road – 135 & Major District Road – 132), this site covers 51 villages, spread over three blocks. By monitoring various aspects of population in a longitudinal fashion, the surveillance activities facilitate understanding of the determinants and causal linkages of various health conditions.

SOMAARTH focuses on establishing an integrated surveillance system that is simple, feasible, affordable, and sustainable and addresses health in the context of environment. It also aims to provide a platform for multi-disciplinary policy- and program-relevant studies with multisectoral collaboration in the same geographic area. SOMAARTH has two major components

  • Demographic Surveillance: Periodic documentation of the size, structure and distribution of populations in the area, and spatial and/or temporal changes in response to birth, migration, aging and death.
  • Environmental Surveillance: Periodic documentation of physical structures, natural features and climatic conditions. This includes documentation of important social, economic, agriculture, industrial, businesses, markets, institutions (including education), components of urbanization, built environment and town planning activities, traffic patterns, and use of pesticides and other chemicals. SOMAARTH has a met station and is building systematic monitoring of air and water quality into their regular monitoring schemes.
