Gender differences in body composition, dietary patterns, and physical activity: insights from a cross-sectional...

Area of Science:

• Nutrition science
• Human physiology
• Behavioral science

Background:

• Body composition, dietary patterns, and physical activity are interconnected.
• Gender-specific differences in health behaviors are not fully understood.
• Identifying these differences is crucial for effective health interventions.

Purpose of the Study:

• To investigate gender-specific differences in food preferences and eating behaviors.
• To explore the relationship between body composition (fat mass to fat-free mass ratio), diet, and physical activity.
• To inform targeted nutritional and lifestyle interventions.

Main Methods:

• Cross-sectional study of 1,333 adults (18-65 years).
• Participants categorized into tertiles based on fat mass to fat-free mass (FM-to-FFM) ratio.
• Data collected on dietary choices, eating behaviors, and physical activity.

Main Results:

• Significant gender differences in hunger timing and food preferences (males: processed/red meats; females: cooked vegetables).
• Eating behaviors (meal skipping, uncontrolled eating, nocturnal eating, taste preferences) varied by gender and FM-to-FFM ratio.
• Higher FM-to-FFM ratios correlated with reduced physical activity, especially in sports.

Conclusions:

• Body composition and BMI significantly influence health-related behaviors.
• Gender-specific differences in diet and activity necessitate tailored interventions.
• Understanding these interactions promotes healthier lifestyles.
