Sampling and Data Collection
Is it all households in the Sleman district that is Sleman HDSS respondents?
No, HDSS takes samples from the HDSS Sleman survey population, which are residents who live in Sleman Regency for 6 consecutive months. The sampling method used a two-stage stratified random design.
How to choose the Sleman HDSS respondent?
The sample was selected using two-stage cluster sampling with probability proportionate to size. In the first stage, 216 clusters were randomly selected from 3513 clusters in Sleman Regency. The selection of clusters is carried out with the provisions of 85% (184 clusters) in urban areas and 15% (32 clusters) in rural areas. In the second stage, systematic random sampling was conducted to select 25 households from each cluster. A total of 5,127 households participated in the Sleman HDSS cycle 1.

No, HDSS has 3 types of respondents:
- a. The main respondents are household members aged 18 years and know the condition of the household and other household members. (Usually, the head of the family or spouse). The main respondents answered household-level questions that were asked to all household members such as questions on changes in demographic data, infectious diseases, ownership, etc.
- b. Individual panel respondents are respondents aged >25 years in each HDSS Sleman household and selected respondents using the Kish Grid Sampling method. Individual panel respondents answered questions related to themselves such as questions on the module on risk factors for non-communicable diseases, quality of life, and mental health.
- c. The main caregivers are household members who are the primary caregivers of infants/toddlers/children. The modules that were asked to the primary caregivers were the module on maternal and child health, immunization, breastfeeding, and complementary feeding.

The main respondents are not always the same every year. While the questions in the individual panel module are asked to the same individual in each cycle.
What is the individual panel?
An individual panel is a group of HDSS Sleman respondents aged >25 years who are followed by health conditions. Respondents in this panel are representatives (1 individual per household) of HDSS Sleman households selected using the Kish Grid Sampling method. Individual panels conducted direct interviews asking questions related to non-communicable diseases, risk factors for non-communicable diseases, mental health, and quality of life.
What is a refreshment sample?
The refreshment sample is households participating in Sleman HDSS starting from cycle 3. The addition of this household sample is done to readjust the number of Sleman HDSS samples with the results of calculating the minimum sample requirement.
Data Availability

Technical Dataset and Data Processing
How do determine social economic status at the household level?
The socioeconomic status (SES) in HDSS Sleman shows the socioeconomic status at the household level. The socioeconomic status is determined based on several variables in the asset ownership module and is calculated using Principal Component Analysis (PCA).
Is it household expenses that could use as social-economic status in the next cycle?
Expenditures may change in the following year, so it is not appropriate to use it as an economic status in other cycles. HDSS Sleman has data on economic status based on asset ownership. This economic status is more stable, so it is only updated once every 4 years. Cycle 1 economic status can be used for cycles 2 and 3.
What is missing data?
Missing data in the Sleman HDSS dataset can be caused by several things as follows:
- The member of the household is not in the HDSS Sleman household because he has moved, died, or has not joined the household.
- Respondents did not provide answers.
- Based on the answers to the previous questions and the skip pattern, this question cannot be answered.
How do weighting in Sleman HDSS?
There are two types of weights provided by HDSS Sleman: design weight and post-stratification weight.
Design weight is the weight that is considered for selecting the sample. These weights are provided directly by BPS Indonesia, the party that designed the sampling. A sampling of census blocks according to strata (Rural and Urban) and the proportion of Rural and Urban in Sleman Regency. (Variable name = weight).
There are two types of post-stratification weights used by HDSS:
- Weight according to the proportion of sex and age group of the population of Sleman (variable name = weight).
- Weight according to the proportion of sex and age group and the sub-district where the residents of Sleman live (variable name = psweightkec).

Is there a charge for using HDSS data?
There is a data usage fee as stipulated in Gadjah Mada University Rector Regulation Number 6 of 2019 concerning Amendments to Gadjah Mada University Rector’s Regulation number 15 of 2018 concerning UGM Tariff Standards 2018 dated 6 May 2019 However, the FK-KMK UGM research team can use the data without being charged cost.
How long does it take for a proposal for data usage approval?
The whole process takes 3-4 weeks for the dataset to be received.
Are the criteria for publication only submitted or must it be accepted?
For now, it’s just submitted.
Are there minimal criteria for publication?
HDSS Sleman does not set minimum criteria for the journals that the researcher is aiming for. Researchers are only asked to follow the terms of writing an acknowledgment and authorship as stated in the Statement Concerning The Use of Sleman HDSS Data. National and international publications are allowed. Provided that the acknowledgment conditions for HDSS are included.
If the dataset has been obtained, does HDSS provide data analysis consulting services?
The data management team provides consulting services related to dataset technical matters, such as variable definition, amount of data, and inter-cycle variable linkage. If researchers need a consultation with HDSS experts, they can help connect researchers with FK-KMK UGM researchers or lecturers with appropriate expertise. However, if any fees are required for consultation, these costs will be borne by the researcher.
Is there any point that must be mentioned in a list of requested variables?
In this form, the researcher is asked to explain the exclusion and inclusion criteria of his research. It is necessary to select a sample from the Sleman HDSS dataset. For example, the inclusion criteria could be filled with “women, ages 15-60, who answered questions about hypertension status”. If the inclusion criteria use a criterion that is a combination of several variables, the researcher must provide an operational definition. For example, if a researcher uses the criteria for “severe injury”, it is necessary to explain the definition of “severe injury”. For example “it is called a serious injury if the questions ptm20a==1 & (ptm25a==1 | ptm25b==1 |ptm25c==1).
For biological samples (eg. Blood), could Sleman HDSS facilitate? If it could be, could it do in the next cycle? How about the funding?
HDSS and Biobank have collaborated on blood sampling for general use. HDSS also facilitates nested sampling. The terms and costs will be charged to researchers. Because HDSS has a population of data that is shared, there is a sharing principle if researchers want to take biological samples. In nested research, the data is generated for researchers, but after the use of the data is considered complete, HDSS hopes that there is an agreement that the data will be donated, as well as biosamples. So that there will be more data in HDSS and the possibility to utilize more data.
Nested Research
What is nested research?
Researchers can collect direct data (primary data) in the HDSS Sleman research area by following the applicable procedures. The benefits of nested research are as follows:
- Get research data with better sample selection.
- The efficiency of time, cost, and energy because data collection can be organized by HDSS Sleman.
- Enriching data analysis because researchers can take advantage of data that has been routinely collected by HDSS Sleman.
How is the system data primer collection using the HDSS sampling frame?
Submit to the ethics committee, later a recommendation will be given to use HDSS sampling frames, and facilitated by HDSS.
Research Ethic
Is there any ethical issue about coordinating living in respondents?
