Can individuals meet multiple physical activity and dietary behavior goals?

Area of Science:

• Cardiovascular Health
• Behavioral Science
• Dietary Interventions

Background:

• Blood pressure control is crucial for preventing cardiovascular disease.
• Lifestyle modifications, including diet and physical activity, are foundational to hypertension management.
• The effectiveness of goal-setting in conjunction with dietary interventions requires further investigation.

Purpose of the Study:

• To determine if individuals assigned more behavioral goals were more successful in achieving them compared to those with fewer goals.
• To evaluate the impact of different intervention strategies on goal attainment for blood pressure control.

Main Methods:

• A randomized controlled trial involving 810 participants was conducted.
• Intervention groups included advice-only, established guidelines (sodium reduction, increased physical activity), and established guidelines plus the DASH diet.
• Goal achievement was assessed at 6 and 18 months.

Main Results:

• At 6 months, 44.6% of participants on the Established plus DASH diet met at least three goals, significantly higher than other groups (P<0.0001).
• The group with the most behavioral goals to achieve demonstrated a higher rate of goal attainment.
• At 18 months, 33.5% of the Established plus DASH group continued to meet at least three goals.

Conclusions:

• Individuals assigned a greater number of behavioral goals were more likely to achieve them.
• The DASH diet, combined with established guidelines, significantly enhances the ability of participants to meet multiple health objectives.
• Setting ambitious yet achievable goals within a structured intervention framework promotes better health outcomes.
