●​ The occurrence of this " silent killer " is more prevalent in the southeastern United States, particularly among African Americans. ●​ Additional risk factors include age above 60, a sedentary lifestyle, and hyperlipidemia. Fasting Lipid Profile ●​ Adults should undergo a fasting lipid profile at least once every five years. ●​ Optimal values include total cholesterol under 200 mg/dL, triglycerides under 150 mg/dL, low-density lipoprotein (LDL, the "bad" cholesterol) under 100 mg/dL, and high-density lipoprotein (HDL, the "good" cholesterol) above 40 mg/dL for men and 50 mg/dL for women. Colorectal Screening ●​ Regular screening, beginning at age 50, is essential for preventing colorectal cancer. ●​ Screening methods encompass fecal occult blood tests (FOBT), sigmoidoscopy, colonoscopy, double-contrast barium enema (DCBE), or digital rectal exams (DRE). Prostate Screening ●​ Men should initiate prostate-specific antigen (PSA) testing at age 50. Mammograms ●​ Women should consider obtaining a baseline mammogram between ages 40 and 50, taking into account their individual risk factors. Applying Knowledge of Pathophysiology to Health Screening Health screening is a crucial component of preventive healthcare, and understanding the underlying pathophysiology of diseases and disorders is essential for tailoring effective screening strategies. Screening guidelines are often based on knowledge of risk factors, disease progression, and the demographics of populations. Here are examples of how knowledge of pathophysiology informs health screening: ●​ Chlamydial Infection Screening : Screening for chlamydial infections is targeted at sexually active women aged 25 and younger, as this group is at higher risk. The screening approach is based on the understanding that this specific age group is at higher risk due to lifestyle factors. ●​ Colorectal Cancer Screening : Starting at age 50, routine colorectal cancer screening is recommended. However, those with higher pathological risk factors, such as a family history of colorectal cancer, may need earlier or more frequent screenings. ●​ Depression Screening : Depressive disorders often have psychological triggers. Those who have experienced major life events or have poor coping skills might benefit from depression screening.
