Several factors can affect the follow-up rate in epidemiological studies:
Study Design: Complex or lengthy studies may have lower follow-up rates due to participant fatigue or disinterest. Participant Characteristics: Factors such as age, socioeconomic status, and health literacy can influence follow-up rates. Study Management: Effective communication, reminders, and incentives can improve follow-up rates. Geographical Location: Participants in remote or underserved areas may have lower follow-up rates due to logistical challenges.
