Health Recommendations for Adults in Their 40s
Adults in their 40s should undergo screening for abnormal blood glucose and type 2 diabetes if they are overweight or obese, with rescreening every 3 years if initial results are normal. 1
Cardiovascular Risk Assessment and Management
Blood Glucose and Diabetes Screening
- Screen all adults aged 40-70 years who are overweight or obese (BMI ≥25 kg/m²) for abnormal blood glucose using fasting plasma glucose, hemoglobin A1C, or oral glucose tolerance test. 1
- Rescreening every 3 years is reasonable for those with initial normal results. 1
- Risk factors warranting earlier or more frequent screening include family history of diabetes, history of gestational diabetes, polycystic ovarian syndrome, or membership in high-risk racial/ethnic groups. 1
- For patients with abnormal glucose (impaired fasting glucose or impaired glucose tolerance), refer to intensive behavioral counseling interventions focusing on diet and physical activity. 1
Lipid Screening and Statin Therapy
- Obtain a screening lipid profile at age 40 years and periodically (every 1-2 years) thereafter. 1
- For adults aged 40-75 years with one or more cardiovascular risk factors (dyslipidemia, diabetes, hypertension, or smoking) and a calculated 10-year cardiovascular disease risk of 10% or greater, initiate low- to moderate-dose statin therapy. 1
- For those with 10-year risk of 7.5% to 10%, statin therapy provides at least a small benefit in reducing cardiovascular events and mortality. 1
- If diabetes is present, initiate at least moderate-intensity statin therapy (atorvastatin 10-20 mg, rosuvastatin 5-10 mg, simvastatin 20-40 mg, or pravastatin 40-80 mg daily) regardless of baseline lipid levels. 2, 3
Blood Pressure Monitoring
- Screen for hypertension at every clinical encounter, as treatment of hypertension provides substantial cardiovascular benefits. 1
- Target blood pressure should be individualized based on presence of diabetes or other comorbidities. 1
Lifestyle Interventions
Weight Management and Physical Activity
- For adults who are overweight or obese, recommend intensive lifestyle intervention targeting 5-7% weight loss through dietary changes and increased physical activity. 1
- Encourage regular exercise including aerobic activity, weight-bearing exercise, and resistance training. 1
- Intensive lifestyle interventions combining dietary modification with aerobic and resistance training provide multiple benefits including improved physical fitness, increased HDL cholesterol, lowered blood pressure, and reduced waist circumference. 1
Dietary Recommendations
- Recommend reduction of saturated fat, trans fat, and cholesterol intake. 1
- Increase intake of omega-3 fatty acids, viscous fiber, and plant stanols/sterols. 1
- Emphasize optimal nutrition with adequate protein intake. 1
Smoking Cessation
- Counsel all patients on smoking cessation, as smoking is a major modifiable risk factor for cardiovascular disease. 1, 4
Cancer Screening
Colorectal Cancer
- Begin colorectal cancer screening at age 45-50 years for average-risk individuals with life expectancy greater than 5 years. 4, 5
Breast Cancer (Women)
Cervical Cancer (Women)
Immunizations
- Ensure tetanus-diphtheria vaccination is up to date (booster every 10 years). 4, 5
- Consider influenza vaccination annually. 4
Additional Screening Considerations
Depression Screening
- Screen for depression, particularly in patients with diabetes or other chronic conditions. 1
Thyroid Screening (Women)
- Screen women for thyroid disease. 5
Sexual and Reproductive Health
- Assess for sexual problems and provide appropriate counseling. 5
- For women, discuss calcium and vitamin D intake for bone health. 5
Common Pitfalls to Avoid
- Do not wait until symptoms develop to screen for diabetes in overweight/obese adults—early detection allows for prevention of progression through lifestyle interventions. 1
- Do not use age alone to determine statin eligibility—calculate 10-year cardiovascular risk using validated tools and consider individual risk factors. 1
- Do not prescribe low-intensity statin therapy for patients with diabetes—at least moderate-intensity is required. 2, 3
- Do not overlook the substantial benefits of intensive lifestyle interventions, which are more effective than medications for preventing diabetes progression. 1
