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.
![Page 4: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/4.jpg)
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
![Page 5: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/5.jpg)
Stepwise is a frequent community based survey dealing with prevalence of chronic diseases (diabetes mellitus, hypertension , cardiovascular diseases…etc) 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
![Page 6: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/6.jpg)
Stepwise SurveillanceSTEP 1
• Self Report– Demographics– Physical
activity– Diet– Smoking– Alcohol– NCD’s
STEP 2• Physical
– Height– Weight– BP– Waist
circumference
STEP 3• Biochemical
– Fasting glucose
– Cholesterol– Triglycerides– HDL

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
![Page 8: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/8.jpg)
Sampling frame and designTechnique: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.
![Page 9: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/9.jpg)
Sampling frame and designWorking 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
![Page 10: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/10.jpg)
Sampling frame and designTools: • 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).

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.

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
![Page 31: Ministry of Health and Population Preventive and Primary ... · Preventive and Primary Health Care Sector Epidemiology and Disease Surveillance Unit (EDSU) NON-COMMUNICABLE DISEASE](https://reader035.fdocuments.us/reader035/viewer/2022081523/5fda7031d9506b10270396ee/html5/thumbnails/31.jpg)
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.
