In the digital era we're in, understanding the demographics of social media and mobile phone usage is integral to developing successful health communication strategies. Paid social media advertisements provide a budget-friendly, customizable platform that can dramatically amplify health promotion and recruitment efforts.

Health communication plays a key role in public health, guiding individuals and communities towards informed health decisions and healthier behaviors. However, inequitable design in health communication creates barriers that prevent this guidance from reaching everyone equitably. These barriers often overlook language differences, cultural nuances, and varied levels of health literacy. Our challenge lies in achieving health equity in health communication. This means we must ensure that, regardless of their backgrounds, all individuals can effectively access, understand, and utilize health information.
