CHILILAB was designed to focus on issues related to adolescent health and injury. The entire population of 3 selected townships and 4 communes were invited to participate in the study, included 57161 participants from 17993 household. There are 6 objectives of CHILILAB, includes:
1.Establish a demographic and epidemiologic surveillance system on cyclic morbidity and mortality in Chi Linh district
2.Identify patterns and trends of morbidity and mortality in the district population periodically and longitudinally
3.Provide data on adolescent health especially risk and protective factor affecting adolescent health issues
4.Pilot and evaluate community health intervention strategies periodically in order to form a basic for developing health policies in the locality and elsewhere
5.Improve the procedures for data collection, analysis and application at the community level in a reliable and effective manner

Coverage
Geographic Coverage
Chi Linh is a mountainous town of Hai Duong Province of northern Vietnam. Chi Linh town covers an area of 300,54 square kilometers, contains 17 communes and 3 towns and has a population of 142,278 (50.3% female, 49.7% male). A number of different ethnic minority groups live in the district, including San Diu, Chinese, H'Mong, Tay, Nung and some other ethnic minorities. The population density varies across the district, with higher density in lowland communes and places with access to transportation routes. Approximately 25% of the total population lives in urban areas. The number of adolescents between 15-24 years of age accounts for 19.3% of the total district population according to 1999 population data. Residents receive information, including health information, from several different channels: 100% of the communes/towns are covered with the loud-speaker system; 100% of households have their own radio receivers; about 60% of households have TVs.
Several national roads as well as inter-communal roads run through the town. While the national roads are high quality and therefore can handle a high volume of high speed traffic, the inter-communal roads are ill-maintained due to insufficient funding. As a result, some communes are not very easily accessible. Much of the land in Chi Linh is used for agriculture, including rice and subsidiary dry crop cultivation. In addition, forest resources in the district are currently being exploited. The town also contains two thermal power plants as well as a medical glass plant, a refractory soil mine, and a leather shoe making plant providing employment in the district.

Data Processing
Data Editing
Data collected from the sample population is stored in the database of the CHILILAB in HSPH. Periodical updates of demographic information and socio-economic, cultural, health conditions are extracted from the database for analysis. Findings are then disseminated to the community and policy makers in annual workshops with local authorities, though manuscripts, and factsheets in Vietnamese as well as in English. Individual and household data in CHILILAB could be accessed if the request for data use is sent to the CHILILAB coordinator for consideration.
Other Processing
Data entry software is developed in such a way that there is an automatic error control system that function during the process of data entry. In cases where errors are detected by the data entry clerk or by the software, the relevant surveyor and supervisor are informed and the errors are corrected and households re-interviewed if necessary. All errors are acknowledged and recorded in order to gain experience and improve data collection methods in the future.
Checking data: The contents of 5% of the interviews/household observations will be totally or partly reconstructed by the field supervisors or the field coordinators (HSPH staff) to check the data quality through a random selection (5%) of questionnaires used by the surveyors. The field coordinators, at the same time, are responsible for supervising activities being conducted by the field supervisors. This quality control process will be conducted by comparing interview outcomes of the surveyors and supervisors.
