Abstract
The Nauru-STEPS was a nation-wide representative survey of 15 to 64 year olds with the following objectives:
1. To document the national prevalence and patterns of tobacco use, alcohol consumption, dietary behaviours, physical activity, body mass index, elevated blood pressure, and biochemical markers such as blood glucose and blood lipids in Nauru.
2. To provide reliable and up-to-date information on NCD risk factors for planning and evaluating public health initiatives, and for identifying future demands for health services in managing and treating NCDs.

The planning and implementation of the survey was a collaborative initiative between the Nauru Ministry of Health (MOH), the World Health Organization (WHO) and the Centre for Physical Activity and Health at the Universities of New South Wales and Sydney in Australia. The study was supported by the Australian Agency for International Development (AusAID).

The survey population included non-institutionalised individuals in the 15-64 year-old age category living in Nauru during the survey period. Indigenous Nauruans, I-Kiribati and Tuvaluan residents comprised approximately 90% of the total population (Bureau of Statistics, 2004). The remaining population consisted of Asians (Chinese, Filipinos and other South East Asians), other Pacific islanders and expatriate residents (i.e. Australians, Europeans, New Zealanders).

This latter group was excluded from the sampling frame as they were considered to be highly transient and relatively low users of health services in Nauru. Individuals with mental illness, physical or developmental disabilities were also excluded from the survey.

Sampling

Sampling Procedure
Sample selection - approximately 2,500 randomly selected participants aged 15-64 years
Selection process - using a simple random sampling method
Stratification - stratified by age and sex
Stages of sample selection - initial sample size calculations were performed assuming a prevalence of approximately 10% for major variables of interest (e.g.diabetes), an ability to ascertain an estimated prevalence within approximately 1% of the true prevalence with a 95% confidence level. These calculations suggested that a total sample size of approximately 2,584 in the target population of 15 to 64 year olds would be sufficient for the purposes of this study
Strategy for absent respondent/not found/refusals (replacement or not) - a reserve list of an additional 250 participants was generated for each age/sex group to replace any of the original participants in that age/sex group who were ineligible to participate in the study (i.e. those not being in the country during the survey or those individuals with physical or mental disabilities or already deceased).
Overall, usable data for STEPS 1-3 were obtained from 2,272 participants, with a total response rate of 89.7%. Of
the 2,272 respondents, 1086 were men and 1186 were women.
Response Rate
Usable data for STEPS 1-3 were obtained from 2,272 participants, with a total response rate of 89.7%. Of
the 2,272 respondents, 1086 were men and 1186 were women.
Weighting
Since there is no distinction between rural and urban areas in Nauru, and because closely-related families live in clusters (districts) around the island, cluster sampling would introduce potential bias to the survey. A simple random sampling of individuals within each age/sex stratum (with replacement) avoids this problem and was the strategy of choice for Nauru.

A representative sample of 2,272 participants aged between 15 and 64 years from across Nauru was surveyed, with a total response rate of 89.7%. Of the 2,272 respondents in the survey 1086 were males (47.8%) and 1186 were females (52.2%).

Supervision
A survey team comprising a Project Manager, three Team Supervisors, community health nurses, laboratory technicians, data entry personnel
and administrative staff was formed to co-ordinate planning and data collection.
Type of Research Instrument
The questionnaires or instrument for the Nauru Steps Survey 2004 were the core questions in the STEPS 1-3 instrument remained unchanged (Bonita et al., 2001). The Step 1 questionnaire was administered in each household, which collected various information on household members including sex, age and time spent in schools. The Step 1 questionnaire includes behaviours measures for tobacco use, alcohol consumption, diet, physical activity, history of high blood pressure, history of diabetes and general well being.

In addition to a Step 1 questionnaire, questionnaires were administered in each selected household for peoples age 15-64.

The Step 2 questionnaire is mainly for Physical measurements and it includes measurements of heights and weights, blood pressure and heart rate.

The Step 3 questionnaire is for women respondents for Biochemical measurements and it includes blood glucose, blood lipids and albuminuria.

The questionnaires were developed in English from the Steps 1-3 instruments model Questionnaires. After an initial review the questionnaires were translated back into English by an independent translator with no prior knowledge of the survey.

The survey team agreed for additional social and or environmental items relating to NCD control and prevention to be included in the STEPS 1 questionnaire. Examples of some optional items include self-reported health status, perceived susceptability to diabetes, perceived barriers or factors that would enhance adoption of a healthy lifestyle.

To investigate the prevalence of kidney disease in Nauru, items measuring the albuminuria level were added to STEP 3 measures, but the results for this are not presented in the report. Survey participants were requested to bring their urine sample in a collection jar provided by the staff when they presented for STEP 3. For those who forgot to bring in their sample, their urine was collected on the day of the visit.

All questionnaires and modules are provided as external resources.

Data Processing

Cleaning Operations
Two staff manually double-entered all survey data into EpiInfo 6.04d database. The double data entry process was preceded by a series of data cleaning activities by STEP 1 staff. These activities included identifying and investigating various issues related to ineligible handwriting, duplicate records, data values outside of preset ranges, and inconsistencies between answers to different but related questions. Any inconsistencies noted by the data entry staff were resolved with the STEPS personnel or Team Supervisors before data entry was completed. Data entry was conducted concurrently with data collection.
