Abstract
Background and Objectives: Suicide is one of the public health challenges. It involves the individual, family, and even society. Epidemiological study of suicide is one of the most important measures in primary prevention and integration program for suicide in primary health care system. This study evaluated cases who attempted suicide in Khorasan Razavi Province in 2014-2015.
Methods: This cross-sectional study was performed on individuals who were visited at health care centers of Mashhad University of Medical Sciences from August 2014 to July 2015. Seventeen trained interviewers from 14 countries and three major referral centers collected demographic data, time, reason, and method of suicide. Data were analyzed using descriptive statistics, chi-square test and Mann-Whitney test. P-value<0.05 was considered significant.
Results: Totally, 893 individuals were evaluated which was equals to an annual incidence rate of 21.2 per 100000. Seventy-six percent (675) were female and 57% (496) were in the age group 15-24 years. In both genders, married individuals (61%, 543), high school degree (63%, 548) and a monthly income below 160$ were dominant (80%, 438). The most frequent reason and method for committing suicide was family dispute (47%, 380) and drug poisoning (81%, 632), respectively.
Conclusion: Suicide is mostly being dealt with caution. However, the very first step is to know the current situation completely, so epidemiological studies can elucidate different dimensions of this public health problem.

Abstract
Background and Objectives: Cardiovascular diseases are the leading cause of adult mortality in many developing countries. This study aims to compare the estimation of the ten-year relative risk of cardiovascular events using the Framingham criteria with a native model.
Methods: This population-based cross-sectional study was conducted in 2014, focusing on the adult population (≥16 years) of Mashhad. Stratified random cluster sampling was employed to gather participants' information based on Framingham's criteria. Data mining, utilizing the decision tree algorithm design, was evaluated using Rapidminer v5.3 software and the cross-validation method.
Results: Out of 2978 individuals, 1930 (64.9%) were women and 1041 (35.1%) were men, with a mean age of 43.5±14.7. Applying the Framingham criteria, the ten-year risk levels of cardiovascular disease were estimated as follows: 77.8% at a low-risk level, 13.4% at a medium-risk level, and 8.8% at a high-risk level.
Regarding data mining, model number (1) achieved an accuracy of 79.56%, indicating that the predicted risk levels using the Framingham algorithm matched the observed values at 95.24% for the low-risk level, 90.8% for the medium-risk level, and 33.13% for the high-risk level. As for model number (2), an accuracy of 82.78% was obtained, with the matching values being 98.20% for the low-risk level, 0.42% for the medium-risk level, and 53.01% for the high-risk level.
Conclusion: The Framingham criteria demonstrate limited effectiveness in predicting medium and high-risk levels in the Mashhad population. According to the local model, smoking and high blood pressure in adulthood are the most significant factors in predicting the risk of cardiovascular diseases in young individuals.
