Nutritional knowledge and body mass index: A cross-sectional study.

Area of Science:

• Nutrition Science
• Public Health
• Cardiology

Background:

• Obesity and noncommunicable diseases (NCDs) are significant public health concerns.
• Understanding the relationship between nutritional knowledge and health outcomes in these patients is crucial.

Purpose of the Study:

• To assess the knowledge of food and nutrition among obese patients with NCDs.
• To investigate the association between nutritional status and knowledge levels.
• To identify common sources of nutritional information used by patients.

Main Methods:

• A cross-sectional study was conducted with 263 outpatients at a cardiology hospital in Brazil.
• Participants completed questionnaires on demographics and nutritional knowledge.
• Nutritional status was evaluated using body mass index (BMI), waist circumference (WC), and waist-hip ratio (WHR).

Main Results:

• A significant inverse association was found between BMI, WC, WHR and the level of correct nutritional knowledge.
• Higher education levels and female gender were also associated with better knowledge.
• Television and newspapers were the primary sources of nutritional information for over 60% of patients.

Conclusions:

• There is a significant link between body mass index and an individual's level of nutritional knowledge.
• Patients with obesity and NCDs require enhanced educational resources for better comprehension of their conditions.
