Background: Medical students are at an increased risk of developing substance use and related problems (SURP) because of the inherent stress associated with the professional medical course apart from the developmental risk factors. However, this is under-researched. Moreover, a comprehensive review on the prevalence of SURP among the medical undergraduates (UGs) and associated factors is lacking from India. To fill this gap, the current research work is aimed to review the existing literature on the magnitude of the SURP among UGs of India and its determinants. Methods: PubMed, Medline, and Google Scholar databases were searched for the original articles studying the prevalence of SURP among medical UGs of India, published from inception till date. Non-original articles, studies on behavioral addictions, and those not directly assessing the prevalence of SURP among the medical UGs were excluded. Results: A total of 39 studies were found eligible for the review. Alcohol (current use: 3.2%–43.8%), followed by tobacco (3.7%–28.8%) and cannabis (1.6%–15%), were the common substances used by the medical students. Among the females, an increasing trend of substance use, particularly of nonprescription sedatives (even higher than males), alcohol, and smoking, was seen. Family history, peer pressure, transition from school to college life, and progression in the medical course were important associated factors. Conclusion: Sensitizing medical students and college authorities, increasing the duration of training on SURP in medical curricula, and providing psychological support for the students with SURP could address this issue.
Background and Aim In forensic investigations establishing the identity of a person is a vital step. Stature and sex are important attributes of personal identity. In cases of mass disasters, generally isolated body parts and extremities are recovered as remains and are utilized to ascertain identity of an individual with personal attributes like gender, stature. The present study was conducted to ascertain if the foot length can be reliably used in estimation of stature and gender, and to establish population-specific regression equation and discriminant function analysis in population of Central India. Methods One hundred subjects (50 males and 50 females) between the age group of 20 and 40 years, who are residents of Central India for two generations, were studied. Foot length, of both right and left sides, was recorded for each individual and stature was measured with the help of a stadiometer. Data were subjected to statistical analysis. Results Statistical analysis of the data of the study population showed statistically highly significant differences (p < 0.001) between males and females. Statistically highly significant positive correlation was observed between stature and foot length in males and females. Linear regression equations for stature estimation were derived separately for males and females. The discriminant function analysis, utilizing foot length correctly, classified 78 to 85.1% of cases for respective gender. Conclusion The statistically significant positive correlation between the foot length and stature and accuracy of sex classification by discriminant function analysis indicate the reliability of foot length in predicting stature and gender of an individual.
