Screen for obesity in adults
The Task Force reaffirmed its recommendation to screen all adults for obesity and to offer intensive behavioral interventions to those with a body mass index of ≥30 kg/m2. Helpful interventions include multiple behavioral management activities in group or individual sessions; setting weight-loss goals; improving diet or nutrition; physical activity sessions; addressing barriers to change; active use of self-monitoring; and strategizing ways to maintain lifestyle changes. High-intensity programs involve 12 to 26 sessions a year and result, on average, in a reduction of 6% of body weight.4
Counsel fair-skinned patients to minimize sun exposure
The Task Force now recommends counseling fair-skinned children, adolescents, and young adults (10-24 years of age) about reducing their exposure to ultraviolet (UV) radiation. UV radiation exposure occurs when outdoors in the sun, especially in the middle of the day; and when using artificial sources of UV light, such as an indoor tanning bed. Unprotected UV light exposure is a cause of skin cancer, especially when this exposure occurs in childhood or young adulthood.
Behaviors that protect from UV radiation exposure include using broad-spectrum sunscreen with a sun-protection factor of at least 15, wearing hats and protective clothing, avoiding the outdoors during midday hours (10 am-3 pm), and avoiding indoor tanning. Brief counseling offered in a primary care setting can increase protective behaviors in the targeted age group.
UV light exposure in adults is also linked to skin cancer, but the effectiveness of counseling in this population is less certain and the benefit from protective behaviors is less. In addition, almost all studies of skin cancer prevention have been conducted with fair-skinned subjects, so the Task Force limited this recommendation to those who have fair skin and are between the ages of 10 and 24.5
Screen for intimate partner violence
The USPSTF has changed its recommendation on screening women for intimate partner violence (IPV). Previously it said that the evidence was insufficient to make a recommendation. New evidence has since been published and the Task Force recommends that women of childbearing age (14-46 years, with most evidence for those over age 18) be screened using one of 6 screening tools found to have satisfactory performance characteristics.6 IPV means physical, sexual, or psychological abuse by a current or former partner or spouse, among heterosexual or same-sex couples. To learn more, see “Time to routinely screen for intimate partner violence?” (J Fam Pract. 2013;62:90-92).
Services found to be effective in preventing IPV include counseling, home visits, information cards, referrals to community services, and mentoring support provided by physicians or other health professionals.6
The evidence on screening for the prevention of elder abuse and abuse of vulnerable adults still remains insufficient for a recommendation.
D recommendations
No need for prostate cancer screening, or these other interventions
The list of new D recommendations (interventions that have no benefit or that cause more harm than benefit) includes:
- screening for ovarian and prostate cancer
- using estrogen or estrogen combined with progestin in postmenopausal women for the prevention of chronic conditions
- screening with resting or exercise electrocardiography for the prediction of coronary heart disease events in asymptomatic adults at low risk for such events.
The most controversial D recommendation is to avoid measuring prostate-specific antigen (PSA) to screen for prostate cancer. The Task Force has never endorsed use of the PSA test, previously stating that evidence was not of sufficient strength to recommend for or against it in men <75 years and recommending against it for older men. The evidence report conducted for the reconsideration of this topic provided sufficient evidence that the PSA test results in far more harm than benefit.

The troublesome C recommendation
Proceed with caution with these 2 interventions
The wording of level C recommendations has undergone revision once again. In recognition that some preventive services may benefit select patients—although the overall benefit in the population is small—the USPSTF now states that a C recommendation means that the Task Force “recommends selectively offering or providing this service to individual patients based on professional judgment and patient preferences.” This past year, 2 interventions fell into this category: multifactorial risk assessment and management to prevent falls in community dwelling elders, and counseling adults about a healthy diet and exercise to prevent cardiovascular disease (TABLE).2
