Background <ul><li>Increase in the life expectancy after 65. </li></ul><ul><ul><li>Women: 20+ years </li></ul></ul><ul><ul><li>Men: 17+ years </li></ul></ul><ul><li>Strategies for health promotion and disease prevention must consider: </li></ul><ul><ul><li>age </li></ul></ul><ul><ul><li>pathologic processes </li></ul></ul><ul><ul><li>life expectancy </li></ul></ul><ul><li>Approach must be invidualized </li></ul>
    3. 3. Background <ul><li>Many older persons are motivated </li></ul><ul><li>65-75: most elders are enthusiastic </li></ul><ul><li>Media reports are influential </li></ul><ul><li>There is no consensus about health promotion and disease prevention strategies </li></ul><ul><li>Little evidence based medicine </li></ul><ul><li>Conflicting recommendations from diverse organizations </li></ul>
    4. 4. Background <ul><li>Ageist attitudes (physicians and patients) </li></ul><ul><li>Clinicians are reluctant to recommend tests with potential side effects </li></ul><ul><li>Evidences supports the benefits of health promotion and disease prevention for: </li></ul><ul><ul><li>Cerebrovascular disease </li></ul></ul><ul><ul><li>Cervical CA </li></ul></ul><ul><ul><li>Polio, tetanus, rubella </li></ul></ul><ul><li>Older patients: Scarce evidence (targeting) </li></ul>
    5. 5. Background <ul><li>Primary Prevention: preventing illness before it develops in persons who have no symptoms and who have no evidence of the disease </li></ul><ul><ul><li>Identify risk factors and institute interventions </li></ul></ul>
    6. 6. Background <ul><li>Secondary Prevention: Those interventions used to detect diseases in early and symptomatic stages and prevent them from becoming symptomatic. </li></ul><ul><ul><li>Screening may be useful if the condition being screened for has a high mortality or morbidity, occurs commonly, can be detected easily and can be effectively treated. </li></ul></ul>
