Behavioural interventions for preventing and treating obesity in adults

Area of Science:

• Public Health
• Behavioral Science
• Obesity Research

Background:

• Obesity is a significant public health concern in adult populations.
• Effective behavioral interventions are crucial for obesity prevention and treatment.
• A review of interventions published between 2000 and 2006 is needed to assess current practices.

Purpose of the Study:

• To review existing behavioral interventions for preventing and treating obesity in adults.
• To analyze the characteristics, methodologies, and outcomes of these interventions.
• To provide recommendations for enhancing the effectiveness of future obesity interventions.

Main Methods:

• Systematic review of behavioral interventions for adult obesity published between 2000 and September 2006.
• Analysis of intervention targets (physical activity, nutrition), theoretical basis, duration, implementers, delivery methods, and settings.
• Assessment of intervention impact using adiposity indices, primarily body mass index (BMI).

Main Results:

• Twenty-three interventions were identified, with most targeting both physical activity and nutrition behaviors.
• The majority of interventions lacked an explicit behavioral theory basis and varied in duration (3 weeks to 9 years).
• Fifteen interventions demonstrated positive changes in adiposity indices, while six showed no significant change.

Conclusions:

• Behavioral interventions targeting diet and physical activity show promise in managing adult obesity.
• Incorporating explicit behavioral theories may enhance intervention effectiveness.
• Further research and implementation strategies are recommended to optimize obesity prevention and treatment programs.
