Cardiovascular disease (CVD) is the leading cause of death in the US.¹ Known modifiable risk factors for CVD include smoking, overweight and obesity, diabetes, elevated blood pressure or hypertension, dyslipidemia, lack of physical activity, and unhealthy diet. Adults who adhere to national guidelines for a healthy diet² and physical activity³ have lower cardiovascular morbidity and mortality than those who do not. All persons, regardless of their CVD risk status, can gain health benefits from healthy eating behaviors and appropriate physical activity.

The US Preventive Services Task Force (USPSTF) concludes with moderate certainty that behavioral counseling interventions have a moderate net benefit on CVD risk in adults at increased risk for CVD.

See Table 1 for more information on the USPSTF recommendation rationale and assessment. For more details on the methods the USPSTF uses to determine the net benefit, see the USPSTF Procedure Manual.⁴

Patient Population Under Consideration

This recommendation applies to adults 18 years or older with known hypertension or elevated blood pressure, those with dyslipidemia, or those who have mixed or multiple risk factors such as metabolic syndrome or an estimated 10-year CVD risk of 7.5% or greater. Adults with other known modifiable cardiovascular risk factors such as abnormal blood glucose levels, obesity, and smoking are not included in this recommendation.^5-7 Interventions to reduce CVD risk in those adults are covered in other USPSTF recommendations.

Definitions of Healthy Diet and Physical Activity

The term “healthy diet” is defined as a balance and variety of foods and beverages that assist an individual in achieving and maintaining a healthy weight, support health, and prevent disease. Dietary counseling to promote a healthy diet focuses on increasing consumption of fruits, vegetables, whole grains, fat-free or low-fat dairy, lean proteins, and oils and decreasing consumption of foods with high sodium levels, saturated or trans fats, and added sugars, as recommended by the US Department of Agriculture and the US Food and Drug Administration.¹

Physical activity is broadly defined as any bodily activity that enhances or maintains overall health and physical fitness. The US Department of Health and Human Services recommends that adults 18 years or older engage in at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic physical activity per week in addition to engaging in strengthening activities at least twice per week.^1,8

Assessment of Risk

Cardiovascular risk can be characterized as the elevation of a single risk factor or multiple risk factors (eg, metabolic syndrome). Cardiovascular risk can be estimated through the use of CVD risk tools such as the Pooled Cohort Equations and Framingham Risk Score.^9,10 Cardiovascular disease risk factors covered in this recommendation include dyslipidemia, elevated blood pressure or hypertension, and multiple or mixed risk factors.

Behavioral Counseling Interventions

Behavioral counseling interventions usually combine counseling on a healthy diet and physical activity and are usually intensive, with multiple contacts that include either individual or group counseling sessions over extended periods. Interventions usually involve a median of 12 contacts, with an estimated 6 hours of contact time over 6 to 18 months. Interventions typically involve some 1-on-1 time with an interventionist and include motivational interviewing and behavioral change techniques such as goal setting, problem solving, and self-monitoring. Primary care clinicians as well as a wide range of specially trained professionals, including nurses, registered dietitians, nutritionists, exercise specialists, physical therapists, masters- and doctoral-level counselors trained in behavioral methods, and lifestyle coaches, can deliver these interventions.

Common dietary counseling advice includes reductions in saturated fats, sodium, and sweets/sugars and increased consumption of fruits, vegetables, and whole grains. The Dietary Approaches to Stop Hypertension (DASH) diet, low-sodium diet, and the Mediterranean diet are commonly recommended diets. Physical activity counseling focuses on patients achieving 90 to 180 minutes per week of moderate to vigorous activity.¹¹

Implementation

Primary care clinicians can deliver in-person behavioral counseling interventions, refer patients to behavioral counseling interventions in other settings, or inform patients about media-based interventions. For more information about risk assessment methods and behavioral counseling interventions, see the Additional Tools and Resources section and Table 2.

Additional Tools and Resources

• The Community Preventive Services Task Force recommends several community-based interventions to promote a healthy diet (https://www.thecommunityguide.org/topic/nutrition) and physical activity (https://www.thecommunityguide.org/topic/physical-activity), including community-wide campaigns, social support interventions, school-based interventions, and environmental and policy approaches.
• The US Department of Health and Human Services and the US Department of Agriculture have developed dietary (https://health.gov/our-work/food-nutrition/2015-2020-dietary-guidelines) and physical activity (https://health.gov/our-work/physical-activity/current-guidelines) guidelines.

Other Related USPSTF Recommendations

The USPSTF has several recommendations related to behavioral counseling interventions and the prevention of CVD. These include recommendations on behavioral counseling to promote a healthy diet and physical activity for CVD prevention in adults without cardiovascular risk factors (C recommendation);¹⁴ behavioral weight loss interventions to prevent obesity-related morbidity and mortality in adults (B recommendation);⁶ behavioral and pharmacotherapy interventions for tobacco smoking cessation in adults, including pregnant women (B recommendation);⁷ and screening for abnormal blood glucose levels and type 2 diabetes mellitus (B recommendation).⁵

This recommendation replaces the 2014 USPSTF recommendation on behavioral counseling to promote a healthy diet and physical activity for CVD prevention in adults with cardiovascular risk factors. At that time, the USPSTF recommended intensive behavioral counseling interventions for overweight and obese adult patients with known CVD risk factors, including hypertension, dyslipidemia, impaired fasting glucose or glucose intolerance, and metabolic syndrome.¹⁵ This new recommendation targets adults with known hypertension or elevated blood pressure, elevated lipid levels or dyslipidemia, and mixed or multiple risk factors (eg, metabolic syndrome or estimated 10-year CVD risk of ≥7.5%). In contrast to the previous statement, the current recommendation does not cover adults with impaired glucose tolerance or type 2 diabetes mellitus. This population is covered in a separate recommendation.

Scope of Review

The USPSTF commissioned a systematic evidence review to update its 2014 recommendation on behavioral counseling to promote a healthy diet and physical activity for CVD prevention in adults with cardiovascular risk factors. The scope of this review is similar to that of the prior systematic review, except in the current review the USPSTF excluded studies limited to or predominantly conducted in persons with diabetes or prediabetes. The evidence review did not include interventions specifically focused on weight loss in general populations; however, weight loss trials that targeted adults with relevant CVD risk factors were included in this review.

Benefits of Behavioral Counseling Interventions

The USPSTF considered 94 trials (n = 52,174) in its review.^11,16 Interventions that combined a healthy diet and physical activity were evaluated in 81 trial groups, diet-only interventions were evaluated in 33 trial groups, and interventions involving physical activity only were evaluated in 6 trial groups. Of the interventions reviewed, 6% were considered low-intensity, 49% medium-intensity, and 45% high-intensity. Interventions were defined as low-, medium-, or high-intensity based on the amount of interaction with a clinician (≤30, 31-360, and >360 minutes, respectively). Risk factors targeted in the interventions included abnormal lipid levels (16 trials), elevated blood pressure (32 trials), and multiple or mixed risk factors (46 trials). Most participants in the included trials were overweight or obese, with a mean body mass index of 29.8 (calculated as weight in kilograms divided by height in meters squared) across all trials.

Twenty-nine trials reported on patient health outcomes such as CVD events, mortality, or quality of life.^11,16 Twelve of these trials reported cardiovascular events, and among the trials with a composite outcome of any CVD event (eg, myocardial infarction, stroke, and incidence of peripheral artery disease), the pooled effect showed lower risk among patients receiving behavioral health counseling (pooled relative risk [RR], 0.80 [95% CI, 0.73 to 0.87]; 9 randomized controlled trials; n = 12,551; I² = 0%). Intervention groups also demonstrated lower event rates for both myocardial infarction (pooled RR, 0.85 [95% CI, 0.70 to 1.02]; 6 trials; n = 10,375; I² = 0%) and stroke (pooled RR, 0.52 [95% CI, 0.25 to 1.10]; 4 trials; n = 9800; I² = 0%); however, results were not statistically significant for either outcome.

Eighteen trials of medium- to high-intensity interventions reported on all-cause mortality. The pooled effect did not demonstrate a statistically significant benefit (pooled RR, 0.89 [95% CI, 0.71 to 1.11]; 18 trials; n = 17,939; I² = 0%), although many of these studies were not adequately powered to assess this outcome.

A variety of self-reported quality-of-life measures were reported in 11 trials. Most findings favored the intervention group; however, group differences were generally very small and statistically nonsignificant. The USPSTF considered 91 trials (n = 47,951) that reported intermediate health outcomes.^11,16 Commonly reported intermediate outcomes included objective measures of blood pressure, lipid levels, weight/adiposity, glucose level, and composite cardiovascular risk score. Overall, interventions involving counseling on diet and physical activity led to statistically significant improvements in systolic blood pressure (–1.8 mm Hg [95% CI, –2.5 to –1.1]), diastolic blood pressure (–1.2 mm Hg [95% CI, –1.6 to –0.8]), total cholesterol level (–3.5 mg/dL [95% CI, –5.6 to –1.4]), low-density lipoprotein cholesterol level (–2.1 mg/dL [95% CI, –4.1 to –0.2]), fasting glucose level (–2.3 mg/dL [95% CI, –3.6 to –1.0]), and adiposity-related outcomes such as weight (–1.6 kg [95% CI, –2.1 to –1.1]) and body mass index (–0.5 [95% CI, –0.7 to –0.3]). For all outcomes, improvements were seen at 12 to 24 months of follow-up. The data showed no clear effect modifiers, including intervention intensity, for most outcomes, although weight loss interventions were associated with greater weight loss.

The USPSTF considered 70 trials (n = 43,243) reporting outcomes related to health behaviors such as healthy eating habits and increased physical activity. There was substantial variability in the measures reported, and most outcomes were reported in fewer than 15 trials.^11,16 Most trials included medium- or high-intensity interventions. Overall, behavioral counseling resulted in small, statistically significant improvements in saturated fat consumption (percentage of calories from saturated fat) (pooled mean difference, –1.5% [95% CI, –1.9 to –1.1]), increased consumption of fruits and vegetables (pooled mean difference, 0.7 servings/d [95% CI, 0.1 to 1.3]), and increased fiber intake (pooled mean difference, 1.3 g/d [95% CI, 0.1 to 2.6]). Nine trials among adults with hypertension or elevated blood pressure who were counseled to reduce sodium intake showed reduced urinary sodium levels (pooled mean difference, –18.0 mmol/L [95% CI, –34.8 to –1.2]).

Fifty trials of behavioral counseling interventions reported some type of physical activity outcome (n = 34,028); however, there was no consistent evidence of benefit. Outcome reporting was highly variable for the type of measurement reported (eg, any activity or moderate to vigorous activity) and the unit of measurement (eg, minutes per week or kJ per kg per day). The pooled effect of continuous outcomes was not statistically significant (pooled standardized mean difference, 0.06 [95% CI, –0.03 to 0.14]). However, among trials in which there was a study-defined physical activity goal (usually 90 to 180 min/wk of moderate to vigorous physical activity), intervention groups had a higher likelihood of meeting that goal (pooled RR, 1.22 [95% CI, 1.00 to 1.50]; 11 trials; n = 5887; I² = 91%]).

Harms of Behavioral Counseling Interventions

Of the 94 trials reviewed by the USPSTF, only 20 specifically reported on harms, and 8 of these specifically reported no adverse events.^11,16

Few trials reported details about the adverse events, but most were minor. In trials evaluating physical activity interventions, a few participants reported minor musculoskeletal injuries. Serious adverse events were rare.^11,16 There was no consistent evidence that behavioral counseling interventions led to paradoxical changes in intermediate or behavioral outcomes.

Response to Public Comments

A draft version of this Recommendation Statement was posted for public comment on the USPSTF web site from May 12, 2020, to June 8, 2020. Several comments noted that the interventions in studies were mainly provided by nonmedical professionals and requested clarification on which types of professionals could provide these services. The USPSTF recognizes that many of the studied interventions were carried out by nonphysicians and that multiple types of professionals, both medical and nonmedical, can deliver them. Language was added to clarify this point. Respondents also suggested that the recommendation highlight certain interventions such as low-carbohydrate and plant-based diets, intermittent fasting, telehealth, and wearable technologies. The USPSTF reviewed studies that included a wide range of healthy dietary advice; however, only the DASH and Mediterranean diets were examined in more than 1 study. Additionally, recommendations from plant-based and low-carbohydrate diets are included in most recommendations for a healthy diet. There were limited studies on telemedicine-based interventions and wearable technology. The USPSTF calls for more research in these areas.

Several comments noted the disparities among patient populations in access to healthy food and requested more information on how to provide behavioral counseling services to diverse populations. The USPSTF recognizes that there are large disparities in access to resources that support a healthy diet and increased physical activity. The recommendation statement includes links to resources (eg, The Community Guide) that may help address these issues. Additionally, the USPSTF calls for more research on low-intensity approaches that work best in lower-resource settings.

The USPSTF identified several gaps in the evidence where more research is needed.

• Very few trials had sufficient sample size and follow-up to assess the effect on CVD events such as myocardial infarction or stroke and mortality. Larger studies with longer-term follow-up would be valuable to assess the effect of interventions on these outcomes.
• Reporting of behavioral outcomes was highly variable and often incomplete. Greater consistency and standardization of outcomes, specifically those for physical activity and diet, are needed to better understand the range of effects and interpret the pooled effects.
• There was little literature on the use of technologies such as wearable activity trackers. These may be useful tools to increase engagement in physical activity as well as for providing objective data on physical activity outcomes. In addition, more studies are needed that include online resources such as daily caloric intake applications or other low-intensity approaches that may be valuable in low-resource settings.
• Despite the large number of included trials reviewed by the USPSTF, there were few replication studies. Large replication studies of interventions showing reductions in CVD events are urgently needed.

Numerous organizations, including the American Heart Association/American College of Cardiology, the Academy of Nutrition and Dietetics, and the US Department of Veterans Affairs/Department of Defense have recommendations on behavioral counseling for adults with CVD risk factors.^17-19 Most recommend that adults adhere to a healthy diet that includes a balanced diet low in sodium and saturated fats and engage in regular physical activity. For example, the American Heart Association and the American College of Cardiology recommend that clinicians use counseling interventions to promote a healthy diet and physical activity (consistent with US Food and Drug Administration/Department of Health and Human Services guidelines) for all adults.¹⁷ For adults with elevated blood pressure or hypertension, these organizations specifically recommend weight loss, a heart-healthy dietary pattern, sodium reduction, dietary potassium supplementation, increased physical activity with a structured exercise program, and limited alcohol consumption.

The American Association of Clinical Endocrinologists and the American College of Endocrinology have recommendations for adults with dyslipidemia and metabolic syndrome that include 30 minutes of moderate-intensity aerobic activity 4 to 6 times weekly with strength training 2 times weekly.²⁰ Dietary goals should include a reduced-calorie diet consisting of fruits and vegetables, grains, fish, and lean meats. The intake of saturated fats, trans fats, and cholesterol should be limited.²⁰ The Academy of Nutrition and Dietetics recommends nutritional counseling provided by a registered dietitian nutritionist as well as regular aerobic activity to reduce blood pressure in adults with hypertension.¹⁸

The American Academy of Family Physicians refers to and affirms the 2014 USPSTF recommendation on behavioral counseling to prevent CVD.²¹ The American College of Physicians does not currently have a clinical recommendation on behavioral counseling to promote a healthy diet or physical activity in adults.

Additional Information: The US Preventive Services Task Force (USPSTF) makes recommendations about the effectiveness of specific preventive care services for patients without obvious related signs or symptoms. It bases its recommendations on the evidence of both the benefits and harms of the service and an assessment of the balance. The USPSTF does not consider the costs of providing a service in this assessment. The USPSTF recognizes that clinical decisions involve more considerations than evidence alone. Clinicians should understand the evidence but individualize decision-making to the specific patient or situation. Similarly, the USPSTF notes that policy and coverage decisions involve considerations in addition to the evidence of clinical benefits and harms.
