Background: The importance of health promotion and disease prevention in health policy and clinical practice is widely accepted in many countries. However, a large number of medical schools do not dedicate a significant part of their curriculum to these aspects. In Israel, there are no reports on the training of the future physician towards his or her role as health promoter in general, or in the areas of cardiovascular and cancer diseases specifically.

Objectives: To examine the preparation of Israel medical students for the role of health promoter in cancer and cardiovascular diseases.

Methods: The study was carried out over 2 years in two of the four medical schools in Israel: the Sackler Faculty of Medicine at Tel Aviv University and the Faculty of Health Sciences at Ben Gurion University in Beer Sheva. The students (n=172, 70% response rate) were surveyed during 1999-2000 by means of a questionnaire, which included assessment of their training towards the role of health promoter, their clinical experiences and exposure to patients at different stages of illnesses at various medical sites, and the specific skills and relevant knowledge they acquired.

Results: Most of the students’ learning experiences occurred in hospitals with patients at the treatment stage and little time was dedicated to prevention, especially in the community. They demonstrated better knowledge, skills and satisfaction with their learning experiences in CVD than in cancer; and reported having insufficient exposure to several common cancer diseases and lacking examining skills for early detection of cancer. The students in Beer Sheva had significantly more interaction with patients at different stages of CVD and acquired more examination skills than the Tel Aviv students.

Conclusions: A change in the curriculum is urgently needed: namely training medical students in community settings and preparing them to promote the well-being of their patients, including prevention. Attention should be given to launching new learning modes in the pre-clinical and clinical curriculum. We propose that: a) pre-clinical courses include prevention techniques in CVD and cancer, problems of cancer patients, and some examining skills; and b) the clinical phase should integrate oncology concepts and total cancer and CVD care into existing clerkships in the hospitals and in the community.
 

Background: The degree to which serum total cholesterol predicts cariovascular disease is uncertain. While most authors have placed TC among the most powerful risk indicators of CVD, some have claimed that it predicted CVD in women only, or even not at all.

Objective: To determine the predictive value of serum total cholesterol relative to diabetes, smoking, systolic blood pressure and body mass index (kg/m2), for cardiovascular disease mortality in 3,461 occupationally active Israeli males.

Methods: A prospective follow-up was carried out for the years 1987-1998 to determine the effect of age, smoking habits, a history of diabetes, SBP, BMI and TC, at entry, on CVD mortality.

Results: There were 84 CVD deaths during a total of 37,174 person-years follow up. The hazard ratios (95% confidence intervals) for CVD mortality with respect to variables at entry were: diabetes 5.2 (2.1-13.2), age 2.2 (1.7-2.9), smoking 1.3 (1.0-1.8), SBP 1.4 (1.1-2.0), TC 1.5 (1.0-2.1) and BMI 1.2 (0.7-2.2). Among non-obese, non-diabetic, normotensive subjects the hazard ratio of TC adjusted for age and smoking was 1.16 (1.09-1.22) per 10 mg/dl. In the remaining subjects it was 1.04 (0.98-1.12) only. There was a significant interaction between TC and diabetes, hypertension or obesity (P=0.003).

Conclusions: In this population of Israeli males we found an interaction between TC and other risk indicators for CVD. Confirmation is required for the unexpected finding that the predictive value of TC for CVD mortality among non-diabetic, non-obese and normotensive subjects exceeded that among subjects with either of these risk factors.
