Objective:To determine the frequency and intensity of Internet Addiction (IA) among medical undergraduates, using Social Networking Sites (SNS), in Karachi.Methods:A cross-sectional survey was conducted in March-June ‘16 in a private and government medical college of Karachi. Self-administered, Young’s Internet Addiction Test was implemented by 340 medical students to assess the frequency and intensity of IA among SNS profile users for past three years. The structured questionnaire further enquired regarding the social and behaviour patterns relevant to IA and SNS use. Data was analyzed using SPSS 16.Results:Internet Addiction (IA) was found in 85% (n=289) of all study participants. Among them, 65.6% (n=223) were ‘minimally addicted’, 18.5% (n=63) were ‘moderately addicted’, whereas 0.9% (n=3) were found to be ‘severely addicted’. Burden of IA was relatively higher among female medical students as compared to male medical students (p=0.02). There was no significant difference between type of medical college attended and IA (p=0.45). However, statistically significant differences were observed in certain behavioural patterns among addicted and non-addicted medical students.Conclusion:Internet Addiction (IA) is an emerging mental health concern affecting social behaviour patterns of medical undergraduates. However, the burden of IA is relatively higher among female medical students.

ObjectivesIncreased levels of aggression and desensitization of adolescents has been witnessed as a result of exposure to violent social/electronic media content. It is imperative for policymakers to study such behavioral outcomes in order to make sound policies regarding media literacy. The objective of the study therefore was to assess relationship between violent electronic/social media exposure and level of aggression.MethodsA cross sectional study was conducted among adolescents aged 9–19 years in peri-urban slum of Karachi. Content-based Media Exposure scale and Buss and Perry questionnaire, internationally validated tools were used to collect data. Level of aggression was the main outcome variable which was analyzed.ResultsFour hundred and twenty-two adolescents participated in the survey. Usage of television was significantly higher in the younger age group whereas the effect of watching violent content among the adolescents varied. It was observed that 153 (36.3%) respondents felt stressed and 24 (5.7%) felt aggressive after watching violent content on electronic and social media. The contents showing people who fight (39.6 ± 5.6, p-value<0.05), who steal (39.5 ± 7.5, p-value=<0.05) and destroyed someone else’s belongings (40.6 ± 7.6, p-value=<0.05) had a significant effect on the level of aggression. Regression analysis predicted a strong positive association of exposure of violent content with level of aggression (β=0.43).ConclusionsThe usage of violent content on social and electronic media was popular among adolescents, and produced negative effects on the behavior of adolescents. Measures should be taken to introduce media literacy of the children in Pakistan, especially in the peri-urban slums.

Objective: To validate the WHO recommended Mid-Upper Arm Circumference (MUAC) cut-offs for acute malnutrition screening in children younger than five in Karachi, Pakistan. Methods: A cross-sectional study was conducted, including an anthropometric examination following WHO guidelines. Height was measured using Stadiometer and Infantometer. The link between MUAC and Weight-for-Height-Z score (WHZ) for different cut-offs of MUAC for Moderate Acute Malnutrition (MAM) and Severe Acute Malnutrition (SAM) was shown using Receiver Operator Characteristics (ROC) curves and the Youden index. Sensitivity and specificity of MUAC <11.5 cm and ≥11.5 to <12.5cm were determined using WHZ scores of -3 Standard Deviation (SD) and ≥-3 to <-2 SD for SAM and MAM, respectively. Results: Among 499 children, as per WHZ score, 9.6% and 27.1% had SAM and MAM, respectively, whereas according to MUAC, 6.4% and 3.6% had MAM and SAM, respectively. At the maximum value of the Youden index of 55.6%, an optimum cut-off of 12.7cm for screening of SAM with MUAC was found compared to the recommended cut-off of 11.5cm. Similarly, at the maximum value of the Youden index of 57.7%, an optimum cut-off of 13.9cm for screening of MAM with MUAC was found compared to the recommended cut-off of 12.5cm. Conclusion: The current MUAC cut-off of WHO for screening SAM and MAM cases captures only a small percentage of children under five. This needs to be revised to capture children with acute malnutrition for timely treatment in Pakistan.

Objectives: Anxiety and depression are commonly occurring mental disorders in school-going students and if not considered can result in a worse outcome. The objective of our study was to determine the prevalence, risk factors and relationship of anxiety and depression with different variables among high school students of Karachi. Methods: This cross-sectional study was conducted in October - November 2020 in government and private high schools of four districts of Karachi. Two stage cluster sampling was used to select study sites with 400 students inducted. Data was collected by using Aga Khan University Scale of anxiety and depression. Relationship of outcome with predictor variables was examined by applying univariate and multivariate logistic regression analysis. Results: Overall 53.2% participants reported anxiety and depression out of which 78.8% were females. Participants who were studying in private schools (OR 0.39, CI 0.21-0.69 at 95%, p=0.002) and had mothers who were housewives (OR 0.28, CI 0.09-0.83 at 95%, p=0.022) were less likely to develop anxiety and depression. Participants whose fathers and mothers had a history of anxiety and depression were three times more likely to develop anxiety and depression (OR 3.12, CI 1.52-6.41 at 95%, p=0.002) and (OR 3.02, CI 1.39-6.59 at 95%, p=0.005) respectively. Conclusion: The study found a high prevalence of anxiety and depression among high school students. Female students of public sector school and those who had a family history of anxiety and depression were more likely to develop it. Early detection and management of anxiety and depression by screening are necessary to overcome this burden. doi: https://doi.org/10.12669/pjms.38.4.5093 How to cite this:Ibbad S, Baig LA, Ahmer Z, Shahid F.

Introduction: Healthcare ethics is of prime importance and medical students should learn to incorporate it in their everyday practices. Our study aimed to assess and compare the knowledge of medical ethics among students enrolled in a government and a private medical college of Karachi, Pakistan. Methods:A cross-sectional study was conducted from November-December 2019 among 380 medical students who were recruited via convenience sampling after getting their informed consent. A pre-tested, selfadministered structured questionnaire was used to assess knowledge. Data was analyzed by Statistical Package of Social Sciences version 22.Results: Majority, 323 (85%) regarded medical ethics as important while 138 (36.3%) had acquired their knowledge from different workshops. Almost half, 187 (49.2%) had knowledge regarding Hippocratic Oath. When asked regarding ethical scenarios, 69 (18.2%) students in government medical college were of the opinion that a doctor can refuse to perform abortion even if law allows it as compared to 57 (15.0%) in private medical college (p=0.019). Moreover, 80 (21.1%) students in government medical college strongly disagreed that a patient who wishes to die should be assisted in doing so, as compared to 45 (11.8%) in private medical college (p< 0.001). Conclusion:Students had knowledge and were aware of the importance of ethics in their profession. The ones belonging to government medical college held stronger views regarding ethical scenarios as compared to the ones in private medical college.
