Data Collection Notes
Data Source:
The study was conducted in 2005 in nine HDSS sites in Asia, namely Matlab, Mirsarai, Abhoynagar, and WATCH (Bangladesh), Vadu (India), Purworejo (Indonesia), Kanchanaburi (Thailand), Filabavi and Chililab (Vietnam). All sites are members of the INDEPTH Network which was founded to facilitate linkage of existing HDSS through a focused network on HIV/AIDS, malaria, adult health, and NCDs. The HDSSs, which are all in rural settings, cover a representative sample of population at a district level. The HDSS are however self-selected, and do not represent the entire region or country.
Collection Situation:
The questionnaires were translated into local language, and back-translated into English to ensure its validity. Instruments for anthropological and blood pressure measurements were standardised and calibrated routinely in the field in each HDSS. To ensure high quality of data, the group conducted several training sessions. In February 2005, the principal investigators of the selected HDSS met in Ballabgarh HDSS, India, to discuss and finalise the research protocol and instruments. Discussion focused on the adaptation of the WHO STEPS instrument to respective sites’ settings while maintaining comparability of expected results. A show card for standard alcoholic drinks was developed to ensure the comparability of alcoholic drinks measured. A show card for different local fruits and vegetables available, as well as different local physical activities were also developed for similar reasons. In May 2005, each HDSS organised several trainings for field data collectors and supervisors. In each training workshop, the standardised study protocol and instruments were discussed thoroughly, and data collectors conducted pilot tests of both interviews using the standardised questionnaire as well as of physical measurements. During the data collection period, field supervisors conducted regular spot checks, rechecks and data validation procedures to ensure the accuracy and completeness of data obtained.Weekly field meetings were held to enable researchers, supervisors, and surveyors to identify and discuss problems encountered during the data collection processes. Completed questionnaires were sent to the data entry manager.
Instrument:
The pre-tested WHO STEPS questionnaires for chronic NCD risk factors were used to collect core information
Software Details:
EPIDATA: For data entry EPIDATA was Used; STATA:The Data Merging and analysis were done using STATA Version 10.
