Introduction
  • Chronic diseases represent a major problem and
    public health burden in developing countries.
  • It represents 73 of deaths and 60 of global
    disease burden.

4
In Egypt, there is emerging evidence that
diabetes mellitus, obesity, hypertension and
hyperlipidemia contribute to national morbidity
and mortality as it represents about 26 of all
deaths related to chronic diseases. So, Egypt
is in need of conducting national survey to
measure the burden and the actual prevalence of
chronic diseases
Introduction

5
Stepwise is a frequent community based survey
dealing with prevalence of chronic diseases
(diabetes mellitus, hypertension , cardiovascular
diseasesetc) and their behavioral risk factors
obesity, hyperlipidemia, smoking, drinking
alcohol, feeding habits, oil consumption, and
physical activities. Also physical and
biochemical measurements.
Step-wise Surveillance System

6
Stepwise Surveillance
  • STEP 2
  • Physical
  • Height
  • Weight
  • BP
  • Waist circumference
  • STEP 3
  • Biochemical
  • Fasting glucose
  • Cholesterol
  • Triglycerides
  • HDL
  • STEP 1
  • Self Report
  • Demographics
  • Physical activity
  • Diet
  • Smoking
  • Alcohol
  • NCDs

7
The Egyptian population in last census was
estimated to be around 70 millions. Population
10000 randomly selected proportioning to the
total population considering the selected age
group ( 15 65 years) and gender Sites
random selection of 10 Governorates of 27 to
represent the whole geographical area
Sampling frame and design

8
Sampling frame and design
  • Technique
  • Multistage and Stratified Cluster Random
    sampling
  • PSU included Egyptian Governorates as clusters .
    They were stratified into Urban / Frontier /
    Delta / Upper Egypt . 10 of 27 Governorates were
    randomly selected to represent total population
    in a proportionate way.
  • SSU were districts in each governorate
  • TSU were streets and buildings
  • Houses were the end sampling units.

9
Sampling frame and design
  • Working team Consists of
  • Epidemiologist to fill the questionnaire and
    supervise other steps during the interview.
  • Nurse to take blood sample, physical measurements
    (wt, ht, waist circumference), and measure blood
    pressure.
  • Sanitarian from the related health district
    guides the team towards the selected streets and
    building

10
Sampling frame and design
  • Tools
  • Questionnaire we use the international Stepwise
    questionnaire after translating it in Arabic
    using the public traditional Egyptian language to
    facilitate the mission for the interviewer.
  • WHO scales measures for height and weights were
    standardized.
  • WHO supplied the REFLETRON machines and kits for
    biochemical measurements (Fasting blood sugar,
    cholesterol, triglyceride, and HDL).

11
The three steps of the Step-wise survey were
done together The field work of the survey
conducted through the year 2005 starting the
field work from January to December 2005 Data
entry on Access software taking 6 months ( from
January to June 2006) Preliminary descriptive
analysis done using SPSS program.

Sample size
  • Out of 10,000 a total of 9780 adults participated
    in the Egyptian Steps survey.
  • The overall response rate was 97.8

Conclusion and RecommendationStepwise
Surveillance System is important to
  • Collect data and analyze it on an ongoing basis
  • Use data for shaping public health policy
  • Predict future case load of NCDs
  • Monitor impact of public health programs
  • A repeat survey is planned for 2008 if funds
    permit

31
Conclusion Recommendation
  • Standardized sheets for each chronic patients are
    needed to get more data about the Egyptian
    character of patients with chronic diseases
  • Application of Health Program for Chronic
    diseases monitoring is important
  • Nationwide standardized database using software.
