CHRONIC DISEASES – leading cause of death in the world • Leading Chronic Diseases > Cardiovascular disease (Coronary Heart disease) and Stroke > Cancer > Chronic Respiratory diseases > Diabetes • Causation framework CHRONIC DISEASES: basis of prevention Mr. Marc Oneel C. Alvarez, RN, RM, MAN
SOCIAL DETERMINANTS OF HEALTH Diet: High fat Lifestyle modification program Decreased risk for CVD Activity level: Sedentary Alcoholism Mr. Marc Oneel C. Alvarez, RN, RM, MAN
Preventive Management Control of Chronic Diseases • Major Chronic Diseases: • -Heart Disease • -cancer • Stroke • - DM • SOCIOECONOMIC, CULTURAL, POLITICAL & ENVIRONMENTAL FACTORS • Urbanization • Globalization • Aging population Common modifiable risk factor -smoking -Alcoholism -diet • Intermediate Risk Factors: • Raised BP • Raised Blood Sugar • Overweight • Abnormal Lipids • Nonmodifiable Risk factors • Age • Sex • Heredity Mr. Marc Oneel C. Alvarez, RN, RM, MAN
LEVELS OF PREVENTION Mr. Marc Oneel C. Alvarez, RN, RM, MAN
Sensitivity = a/(a+c) • Specificity = d/(b+d) • Predicitive Value + = a(a + b) • Predicitive Value + = a(a + b) Validity by 2 x 2 Contingency Table for SCREENING Mr. Marc Oneel C. Alvarez, RN, RM, MAN
Sensitivity and Specificity are test for accuracy. Absolute Value range from 0 to 1. The nearer the value to 1 means the test is more ACCURATE Mr. Marc Oneel C. Alvarez, RN, RM, MAN
a.) Increase in Prevalence of the Disease = Increase in the Positive Predictive Value and Decrease in the Negative Predictive Value b.) Decrease in Prevalence of the Disease = Decrease in the Positive Predictive Value and Increase in the Negative Predictive Value Mr. Marc Oneel C. Alvarez, RN, RM, MAN
