Abstract

BACKGROUND AND AIMS: Complementary and alternative medicine (CAM) encompasses a wide variety of health practices and products that are generally not included in conventional medicine. This study evaluates knowledge, attitude, and practice (KAP) among medical students toward CAM in Iran. METHODS: In this cross-sectional study, we developed and used a questionnaire to evaluate the KAP of medical students regarding CAM. The sampling method was convenience sampling. Two hundred and twenty medical students who were in their first to three (junior) and the last 2 years of education (senior) participated in this study. The data was collected from January to May 2017. Data analysis employed descriptive statistics, chi-square test, and independent t-test. Statistical significance was set at p-values less than 0.05. RESULTS: Of 220 medical students, 125 respondents were CAM users (56.81%). The score of attitude about CAM was 60.13 ± 10.48 in junior students and 60.81 ± 7.32 among senior students. The score of knowledge about CAM was significantly (p = 0.02) higher in senior students (9.05 ± 4.12) than in juniors (7.74 ± 5.23). Traditional Persian medicine (TPM) was found to be the most commonly practiced CAM by both groups of students and their families. Leeching in students and chiropractic in their families had the lowest CAM use rates. CONCLUSION: Although CAM knowledge was relatively low in medical students, they have a positive attitude toward it. TPM was the most common practice among CAM approaches. It is necessary to incorporate CAM modalities especially TPM education into the curriculum of medical students and other healthcare disciplines to enhance students' knowledge and attitude toward CAM and its role in healthcare.

Summary

Survey of 220 Iranian medical students on CAM knowledge, attitudes, and practice. Traditional Persian medicine ranked most common; leeching among lowest reported by students. Highlights need for curriculum integration.

Why This Matters for Hirudotherapy

This cross-sectional study evaluated the knowledge, attitude, and practice (KAP) of 220 Iranian medical students regarding complementary and alternative medicine (CAM). The findings indicate that while students generally have a positive attitude toward CAM, overall CAM knowledge is relatively low, with leeching reported as having the lowest usage rate among the students surveyed. The study's relevance to ASH's domain is limited and indirect: it documents that leeching is rarely practiced among this student population but does not investigate leeching education or exposure specifically. The data is restricted to a specific demographic of medical students and offers no clinical evidence on the efficacy or therapeutic mechanisms of leech therapy itself.
