Area of Science:

• Public Health
• Health Communication
• Nutrition Education

Background:

• Social media is a primary communication channel for young adults.
• Effective health promotion requires messages tailored to resonate with the target audience.
• Understanding young adults' preferences is crucial for calcium intake interventions.

Purpose of the Study:

• To identify preferred messaging types for young adults to increase calcium consumption.
• To explore factors motivating young adults to consume calcium-rich foods.

Main Methods:

• A cross-sectional, web-based survey administered to young adults aged 18-25.
• Data collected on demographics, message ranking (text vs. Facebook posts), and engagement preferences.
• Qualitative thematic analysis of motivations for consuming calcium-rich foods.

Main Results:

• No significant difference in preference between text messages and Facebook posts.
• Recipe demonstrations, cost-saving tips, and daily intake information were most personally relevant.
• Meal inspiration, awareness posts, and non-dairy calcium sources motivated increased intake.

Conclusions:

• Short, visually appealing messages in young adults' language are recommended for health promotion.
• Content should focus on practical aspects like recipes, cost, and daily requirements.
• Tailored messaging is key to motivating calcium-rich food consumption in young adults.
