UnlabelledNoncommunicable diseases (NCDs) are reaching epidemic proportions worldwide and in India. Surveillance of NCD risk factors are therefore needed as they could help in policy planning and implementation of preventive measures. This article will focus on the experiences gained, and challenges faced, in conducting NCD risk factor surveillance studies in India. Two major surveillance studies on NCDs were conducted in India - the World Health Organization (WHO) - Indian Council of Medical Research (ICMR) NCD risk factor surveillance study and the Integrated Disease Surveillance Project (IDSP). The WHO-ICMR study was a six-site pilot study representing six different geographical locations in India with a sample size of 44,537 including rural, peri-urban/slum and urban. Phase 1 of the IDSP was completed and included seven states in India with a sample size of 5000 per state. The NCD risk factor surveillance showed that high prevalence of diabetes, hypertension and obesity in urban areas with slightly lower prevalence rates in semi-urban and rural areas. There are several challenges in obtaining data on NCD risk factors, which include challenges in obtaining anthropometric and blood pressure measures and in assessing tobacco consumption, diet and physical activity. The challenges in field operations include contacting and convincing subjects, creating rapport, tracking subjects, climatic conditions, recall ability and interviewer skills. Success in surveillance studies depends on anticipating and managing these challengesConclusionImproving country-level surveillance and monitoring is a valuable step in prevention and control of NCDs in India.
