Abstract
Prevalence of non-communicable diseases (NCD) is increasing in sub Saharan Africa (SSA). With rapid urbanisation and poor economic performance new challenges emerge for NCD prevention in the region. This project aimed to contribute to knowledge on the epidemiology of NCD in SSA by exploring the linkages between factors in the socioeconomic and socio-cultural environments, perceived risk for getting cardiovascular disease (CVD) and health-related behaviour among slum dwellers. Specifically it aimed to estimate the levels and determinants of perceived risk for CVD, prevalence of risk factors for CVD and to describe the relationship between perceived risk and health related behaviour. Understanding these context-specific factors informed the design of prevention programs. Quantitative and qualitative methods were employed. A random sample of 5000 adults in the Nairobi Urban Health and Demographic Surveillance System area were interviewed.

The sampling frame for the quantitative cross sectional survey were the NUHDSS database, from which a list of all adults aged 18+ years has been generated. A stratified random sample of individuals were selected according to slum of residence, gender and age group to constitute 20 strata each with 250 respondents. The target sample is around 5000 respondents.

Mode of data collection
Face-to-face [f2f]
Supervision
Team leaders monitored progress in the field and quality control measures were also implemented by them.
Type of Research Instrument
- The questionnaire on Aging and Cardio Vascular disease risk factors and risk perception covers Demographics, care and support, links with place of origin, work history and benefits, chronic conditions and health care utilization health state descriptions, social cultural environment, body image assessment, risk factors and preventive behaviour, perceived personal risk, anthropometrics and biomakers, validation study, further follow up for data collection and referral.

- The questionnaire on Cardio vascular disease risk factors and risk perception for collateral respondents on alcohol consumption: validation of alcohol consumption.

Both questionnaires were administered in Kiswahili to adults aged 18 years and above

Data Processing

Cleaning Operations
Data editing took place at a number of stages throughout the processing, including:

a) Office editing and coding

b) During data entry

c) Structure checking and completeness

d) Secondary editing
Other Processing
Data entry was performed manually at APHRC's headquarters on desktop computers and was done using an in-house built system with a Microsoft Visual Basic and MS SQL softwares.



Data were processed the following steps:



1) Questionnaire reception

2) Office editing and coding

3) Data entry

4) Structure and completeness checking

7) Back up of raw data

8) Export to STATA 10 in files

9) Recoding of variables needed for analysis

10) Structural checking of STATA files
