Cohorts and community: a case study of community engagement in the establishment of a health and demographic surveillance site in Malaysia

Abstract

BackgroundCommunity engagement is an increasingly important requirement of public health research and plays an important role in the informed consent and recruitment process. However, there is very little guidance about how it should be done, the indicators for assessing effectiveness of the community engagement process and the impact it has on recruitment, retention, and ultimately on the quality of the data collected as part of longitudinal cohort studies.MethodsAn instrumental case study approach, with data from field notes, policy documents, unstructured interviews, and focus group discussions with key community stakeholders and informants, was used to explore systematically the implementation and outcomes of the community engagement strategy for recruitment of an entire community into a demographic and health surveillance site in Malaysia.ResultsFor a dynamic cohort, community engagement needs to be an ongoing process. The community engagement process has likely helped to facilitate the current response rate of 85% in the research communities. The case study highlights the importance of systematic documentation of the community engagement process to ensure an understanding of the effects of the research on recruitment and the community.ConclusionsA critical lesson from the case study data is the importance of relationships in the recruitment process for large population-based studies, and the need for ongoing documentation and analysis of the impact of cumulative interactions between research and community engagement.

“…SEACO is a Health and Demographic Surveillance System (HDSS), established in the District of Segamat, in the state of Johor, Malaysia. 30 SEACO covers 5 of the 11 subdistricts (Mukim) in the District of Segamat. This platform collects longitudinal data on the entire population within the five districts.…”

Poor glycaemic control and its metabolic and demographic risk factors in a Malaysian community-based study

“…The study utilised data collected in 2013 as part of a crosssectional community health survey conducted in the South East Asia Community Observatory (SEACO)-a health and demographic surveillance site located in the Segamat District of Johor state in Peninsular Malaysia (Allotey et al 2014b;Partap et al 2017). The survey was of all individuals living in the enumerated community dwellings in the five sub-districts in which SEACO operates and conducted by trained data collectors.…”

Social support and care arrangements of older people living alone in rural Malaysia

“…Data were collected as part of a larger ethnographic study of the population by SEACO. SEACO covers a population of around 40,000 from about 10,400 households (85% response rate) in rural, semi-rural and plantation areas (Allotey et al 2014). In the SEACO area, the geographic spread of the Malay and Chinese reflects patterns of migration and settlement.…”
