    Introduction: Anterior cruciate ligament (ACL) tear is the most common knee ligament injury, especially in athletes. The objective of this study was to investigate relative telomere length (RTL) in blood leukocytes of patients with ACL injury compared with that of controls. Materials and Methods: A total of 187 subjects were invited to participate in this study. Ninety-two patients with clinically diagnosed ACL rupture were enrolled. Ninety-five age and gender-matched healthy controls were also recruited. Blood leukocyte RTL were analysed using quantitative real-time polymerase chain reaction. Results: Patients with ACL rupture had significantly longer relative telomere length than healthy controls (P=0.002). The patients with ACL rupture were classified into two groups according to the sport history of patients which are contact sports and non-contact sports. RTL in patients with non-contact sports was significantly greater than those with contact sports (P=0.006). Moreover, RTL was inversely correlated with body mass index of patients with ACL injury (r=-0.34, P=0.001). Logistic regression analysis indicated that long RTL was associated with a higher risk of ACL rupture. Conclusion: The present study showed that subjects with ACL rupture had significantly greater telomere length compared with their age and gender-matched controls. This finding may result from the increases in physical activity and overexpression of telomerase which acts as a protective mechanism against ACL injury. RTL in blood leukocytes is associated with a risk of ACL rupture.

    BACKGROUND: The World Health Organization recommends continuation with the failing second-line regimen if third-line option is not available. We investigated treatment outcomes among people living with HIV in Asia who continued with failing second-line regimens compared with those who had treatment modifications after failure.

    METHODS: Treatment modification was defined as a change of two antiretrovirals, a drug class change or treatment interruption (TI), all for >14 days. We assessed factors associated with CD4 changes and undetectable viral load (UVL <1,000 copies/ml) at 1 year after second-line failure using linear and logistic regression, respectively. Survival time was analysed using competing risk regression.

    RESULTS: Of the 328 patients who failed second-line ART in our cohorts, 208 (63%) had a subsequent treatment modification. Compared with those who continued the failing regimen, the average CD4 cell increase was higher in patients who had a modification without TI (difference =77.5, 95% CI 35.3, 119.7) while no difference was observed among those with TI (difference =-5.3, 95% CI -67.3, 56.8). Compared with those who continued the failing regimen, the odds of achieving UVL was lower in patients with TI (OR=0.18, 95% CI 0.06, 0.60) and similar among those who had a modification without TI (OR=1.97, 95% CI 0.95, 4.10), with proportions of UVL 60%, 22% and 75%, respectively. Survival time was not affected by treatment modifications.

    CONCLUSIONS: CD4 cell improvements were observed in those who had treatment modification without TI compared with those on the failing regimen. When no other options are available, maintaining the same failing ART combination provided better VL control than interrupting treatment.

    One of the most challenging issues when facing a Quantitative structure-activity relationship (QSAR) classification model is to deal with the descriptor selection. Penalized methods have been adapted and have gained popularity as a key for simultaneously performing descriptor selection and QSAR classification model estimation. However, penalized methods have drawbacks such as having biases and inconsistencies that make they lack the oracle properties. This paper proposes an adaptive penalized logistic regression (APLR) to overcome these drawbacks. This is done by employing a ratio (BWR) of the descriptors between-groups sum of squares (BSS) to the within-groups sum of squares (WSS) for each descriptor as a weight inside the L1-norm. The proposed method was applied to one dataset that consists of a diverse series of antimicrobial agents with their respective bioactivities against Candida albicans. By experimental study, it has been shown that the proposed method (APLR) was more efficient in the selection of descriptors and classification accuracy than the other competitive methods that could be used in developing QSAR classification models. Another dataset was also successfully experienced. Therefore, it can be concluded that the APLR method had significant impact on QSAR analysis and studies.

    Background: Successful aging is a prominent and worldwide theme in gerontology. However, until recently, only few studies were conducted about successful aging in Iran. This study examined whether a healthy lifestyle could predict successful aging among older Iranians. Methods: This cross sectional and descriptive study included 975 older Iranians who were selected through a multistage cluster-quota method from the health centers of Shiraz, Iran. A 5-part questionnaire, including demographic characteristics, the Seniors' Healthy Lifestyle, Barthel Index, the Diner Life Satisfaction and Quality of Life, was used to collect the data. A logistic regression analysis was used in data analysis; data were analyzed using SPSS 21; and significance level was set at α = 0.05. Results: The prevalence of successful aging among older Iranians was calculated at 24.0%. Results of multiple logistic regression analysis revealed that age (95% CI = 1.129- 1.702 and OR = 1.352), gender (95% CI = 0.412-0.764 and OR = 0.687), education level (95% CI = 1.443 - 1.699 and OR = 1.454), job (95% CI = 1.063-1.413 and OR = 1.185), monthly income (95% CI = 1.355-4.055 and OR = 2.272), insurance (95% CI = 0.344-0.842 and OR = 0.540), source of income (95% CI = 1.014-1.298 and OR = 1.145), and healthy lifestyle (95% CI = 0.772 - 0.858 and OR = 0.814) were predictors for successful aging. Conclusion: Findings indicated that successful agers were mostly younger men, with higher education level and monthly income, who had insurance and a job and a healthy lifestyle. Thus, to age successfully, one must maintain and improve healthy lifestyle to prolong one's health.

    OBJECTIVES: Body weight perception may determine the practice of proper weight management. The objective of this study was to measure the agreement between body weight perception and actual body weight status and its associated factors among late adolescents in Kuantan, Malaysia.

    METHODS: A cross-sectional study was conducted from April to October 2018 among 479 adolescents aged 17-19 years old from seven institutions of higher learning in Kuantan. Body weight status was described as body mass index (BMI). Weight and height were measured, and BMI was calculated. Validated, self-administered Figure Rating Scale (FRS) questionnaires were used. Agreement between BMI and body weight perception was calculated using Kappa statistics. Logistic regression was employed to examine the association between body weight perception and sociodemographic variables.

    RESULTS: More than one-third (35.3%) of the respondents misjudged their own body weight. More than one third of the respondents (38.7%) who were underweight, misperceived themselves as having normal weight whilst 31.7% of obese respondents identified themselves as overweight. The agreement between body weight perception and body mass index was moderate (k0.46, p<0.01).

    CONCLUSION: Body weight perception was in moderate agreement with actual weight in late adolescents. Accurate body weight perception is an important factor in late adolescent's weight management behaviour. Hence, health education related to body weight management should be emphasized among this age group.

    BACKGROUND: Although physical activity (PA) in pregnancy benefits most women, not much is known about pregnancy-related changes in PA and its association with gestational diabetes mellitus (GDM) risk. The aim of this study was to identify the trajectory of PA during pregnancy and possible associations with the risk of GDM.

    METHODS: This was a prospective cohort study of 452 pregnant women recruited from 3 health clinics in a southern state of Peninsular Malaysia. PA levels at the first, second, and third trimester were assessed using the Pregnancy Physical Activity Questionnaire. GDM was diagnosed at 24-28 weeks of gestation following the Ministry of Health Malaysia criteria. Group-based trajectory modeling was used to identify PA trajectories. Three multivariate logistic models were used to estimate the odds of trajectory group membership and GDM.

    RESULTS: Two distinct PA trajectories were identified: low PA levels in all intensity of PA and sedentary behavior (Group 1: 61.1%, n = 276) and high PA levels in all intensity of PA as well as sedentary behavior (Group 2: 38.9%, n = 176). Moderate and high intensity PA decreased over the course of pregnancy in both groups. Women in group 2 had significantly higher risk of GDM in two of the estimated logistic models. In all models, significant associations between PA trajectories and GDM were only observed among women with excessive gestational weight gain in the second trimester.

    CONCLUSIONS: Women with high sedentary behavior were significantly at higher risk of GDM despite high PA levels by intensity and this association was significant only among women with excessive GWG in the second trimester. Participation in high sedentary behavior may outweigh the benefit of engaging in high PA to mitigate the risk of GDM.

    Introduction: The east coast hospitals of Malaysia are regularly stricken by flood disaster and nurses make up the majority of frontline responders in disaster. So, they should equip themselves with knowledge and skills related to disaster management. The objective of this study was to explore the factors associated with attitude and practice in disaster management among critical care nurses in the east coast hospitals of Malaysia. Methods: This was a quanti- tative study with a descriptive cross-sectional study design that were involved 250 critical care nurses from the east coast hospitals of Malaysia by used stratified random sampling method. Data were collected by using a validated questionnaire. Multiple logistic regression analysis was used to determine the factors associated with attitude and practice in disaster management. Results: A majority of the critical care nurses had a positive attitude (92.4%, n=231) and adequate practice (80%, n= 200) in disaster management. Among the selected factors studied, attending disaster training/ education was significantly associated with attitude (AOR 4.23, 95% CI: 1.474, 12.144, p = 0.007) and practice (AOR 4.203, 95% CI: 2.102, 8.402, p = 0.000). Disaster response experience had a significant association with practice (AOR 2.697, 95% CI: 1.122, 6.479, p = 0.027) but no significant association with attitude. Level of education, years of service and workplace showed no significant association with attitude and practice in disaster management. Conclusion: This study revealed that disaster training/ education was one of the factors that would ensure positive attitude and adequate practice in disaster management among critical care nurses in the east coast hospitals of Malaysia. Therefore, it is recommended for disaster management programme to be included in continu- ing education training for critical care nurses to ensure them to be well-prepared and respond competently when disaster happen.

    Introduction: Loneliness is a major social problem among the elderly that has gone through almost all countries in the world. Even though loneliness is seen as the health-threatening but, the loneliness assessment is still marginal- ized in routine medical check-up for every senior citizen. Methods: This is a sequential explanatory mixed-method study with a cross-sectional community survey was conducted among 380 community residence elderly followed by in-depth interview among eight respondents. This study aims to measure the loneliness and to explore loneliness experienced by older adults. Data were collected using the short form of Social and Emotional Loneliness Scale for Adults (SELSA-S) and data were analysed using SPSS (version 23.0) for windows. In the qualitative study, eight re- spondents were interviewed face-to-face and data were analysed using thematic analysis Braun and Clarke (2006). Results: The results revealed that 37.2% of respondents had loneliness. Bivariate analyses showed the age, level of education and marital status were significantly associated with loneliness. The results of multiple logistic regression discovered gender (OR=1.75,95%CI:1.04-2.93; p=0.03) and marital status (OR=2.24,95%CI: 1.33-3.77;p= 0.002) were a significant predictor of loneliness. In a qualitative study, the result showed two main themes were recorded as causes of loneliness among the elderly are ‘changing the lifestyles’ and ‘ineffective communications. The sub-themes included ‘loss of someone who significant’, ‘limited physical mobility’, ‘all alone’ and ‘no support’. Conclusion: The issue of loneliness needs critically to be addressed even though Malaysia has not reached the ‘aging population’, but the loneliness prevalence experienced by the older adult has similarities with other countries that have attained that status.

    INTRODUCTION AND HYPOTHESIS: Our primary objective was to study outcomes of patients with intrinsic sphincter deficiency (ISD) following mid-urethral slings (MUS) at 1-year. Our secondary objective was to delineate factors affecting success in these patients.

    METHODS: Six hundred eighty-eight patients who had MUS between January 2004 and April 2017 were reviewed retrospectively; 48 women were preoperatively diagnosed with ISD. All completed urodynamic studies and validated quality-of-life (QOL) questionnaires at baseline and 1 year. Primary outcomes were objective and subjective cure of stress incontinence, defined as no involuntary urine leakage during filling cystometry and 1-h pad test < 2 g and negative response to Urogenital Distress Inventory-6 Question 3. Ultrasound was performed to determine tape position, urethral mobility and kinking at 1 year.

    RESULTS: Women with ISD had significantly lower objective and subjective cure rates of 52.1% and 47.9%, respectively, compared to an overall of 88.2% and 85.9%. QOL scores significantly improved in those with successful surgeries. The sling type did not make a difference. Multivariate logistic regression identified reduced urethral mobility [OR 2.11 (1.24-3.75)], lower maximum urethral closure pressure (MUCP) [OR 1.61 (1.05-3.41)] and tape position [OR 3.12 (1.41-8.71)] to be associated with higher odds of failed slings for women with ISD.

    CONCLUSIONS: Although there are good overall success in women undergoing MUS, those with ISD have significantly lower cure rates at 1 year. Factors related to failure include reduced urethral mobility, low MUCP and relative tape position further away from the bladder neck. Optimal management of patients with ISD and reduced urethral mobility remains challenging.

    Objective: Fatigue is the most frequently reported symptom experienced by cancer patients and has a profound effect on their quality of life (QOL). The study aimed to determine the impact of fatigue on QOL among breast cancer patients receiving chemotherapy and to identify the risk factors associated with severe fatigue incidence.

    Methods: This was an observational prospective study carried out at multiple centers. In total, 172 breast cancer patients were included. The Functional Assessment of Chronic Illness Therapy-Fatigue Questionnaire was used to measure QOL, while the Brief Fatigue Inventory (BFI) was used to assess the severity of fatigue.

    Results: The total average mean and standard deviation of QOL were 84.58±18.07 and 4.65±1.14 for BFI scores, respectively. A significant association between fatigue and QOL was found in linear and multiple regression analyses. The relationships between fatigue severity and cancer stage, chemotherapy dose delay, dose reduction, chemotherapy regimen, and ethnicity were determined using binary logistic regression analysis.

    Conclusion: The findings of this study are believed to be useful for helping oncologists effectively evaluate, monitor, and treat fatigue related to QOL changes.

    Introduction: Baby-friendly hospital practices and family support are recognised to improve the chances of success- ful breastfeeding. The associations between support and maternal psychological state and breastfeeding problems are less explored. This study aimed to assess the influence of professional and family support on breastfeeding ad- verse events and postpartum depression at 2 weeks and exclusive breastfeeding (EBF) status at 12 weeks postpartum, and to identify predictors of positive outcomes. Methods: 64 primiparous Malaysian mothers were interviewed face-to-face, at 2, 6 and 12 weeks post-delivery, to collect data regarding family support, hospital and infant feeding practices, breastfeeding problems and pain, maternal perceptions and depression. Logistic regression and correlation were used to ascertain associations between support and EBF, adverse events and postpartum depression. Results: Neither professional nor family support predicted EBF at 12 weeks. Eighty-five percent of the mothers received high family support, which was associated with lower depression scores (r=-0.36, p=0.005); higher depression scores were associated with more breastfeeding problems. EBF discontinuation before 12 weeks was predicted by maternal perception of insufficient milk supply (OR=8.96, CI=1.78, 45.18). Earlier breastfeeding initiation (r=0.26, p=0.04) and skin-to-skin contact (r=0.25, p=0.048) were associated with lower breastfeeding pain. EBF in hospital was cor- related with fewer breastfeeding problems (r=0.31, p=0.01). Conclusion: Mothers with greater family support suf- fered from less depressive symptoms, which could lower the incidence of breastfeeding problems and prolong EBF duration. Skin-to-skin contact, early breastfeeding initiation and EBF in hospital were associated with less adverse events, thus better compliance with these Baby-Friendly practices is recommended.

    BACKGROUND: Polysubstance use is defined as the use of more than one non-prescribed licit or illicit substance either concurrently or simultaneously. This study aimed to determine the prevalence of single substance users and polysubstance users and 'their associated factors among adolescents in Malaysia.

    METHODS: This study was a secondary data analysis from the National Health and Morbidity Survey (NHMS) 2017, a cross-sectional survey conducted among Malaysian school-going adolescents aged 13 to 17. The NHMS utilised a two-stage stratified cluster sampling. Multivariate Multinomial Logistic Regression analysis was applied.

    RESULTS: The overall prevalence of single substance use and polysubstance use among adolescents were 17.2% and 5.1% respectively. The multinomial model showed a higher likelihood of being single or polysubstance user among male (single user OR = 3.0, poly user OR = 4.6), others Bumiputeras vs Malay (single user OR = 1.7, poly user OR = 5.3), those who live with a single parent (single user OR = 1.2, poly user OR = 1.4), involved in truancy (single user OR = 1.7, poly user OR = 3.6) and being bullied (single user OR = 1.3, poly user OR = 3.4), those who had lack of peer support (single user OR = 1.3, poly user OR = 1.4), poor parental bonding (single user OR = 1.4, poly user OR = 1.8), depression (single user OR = 1.4, poly user OR = 3.2) and those who had no close friend (single user OR = 1.3, poly user OR = 2.7).

    CONCLUSION: Our study highlighted multiple significant associated factors of single and polysubstance use among adolescents in Malaysia. This result can assist in the development of specific intervention and prevention programs targeting high-risk groups.

    AIM: Bed sharing is defined as a newborn sleeping in the same bed with an adult. Bed sharing may put the newborn at risk of suffocation due to accidental smothering.

    METHODS: This was a quasi-experimental study conducted in a tertiary referral hospital. Healthy post-delivery Malaysian mothers were randomly selected and enrolled into the control or the intervention group. On the day of discharge, mothers in the intervention group were interviewed face-to-face in the post-natal ward on their plans for sleeping arrangement with their newborn. After the interview, mothers were advised not to bed share with their newborn and were given an educational leaflet on safe sleeping practices. One week after discharge, mothers in both groups were interviewed over the telephone regarding their actual sleeping arrangements with their newborn using the same questionnaire. Logistic regression was performed to determine factors associated with reduced bed sharing.

    RESULTS: A total of 94 mothers and 95 mothers were recruited to the control and intervention group, respectively. The baseline bed-sharing prevalence was similar between groups: 60.6% in the control group and 61.1% in the interventional group. The proportion of mothers who bed shared with their newborn reduced from 61.1 to 37.9% after the intervention (P

    Introduction: Consumers are advised to read the nutrition labeling when purchasing packaged food. To what extent consumers read nutrition labeling and understand what they read is not well established among Malaysian older persons. Methods: Data from the National Health and Morbidity Survey III (NHMS III) undertaken in 2006 was analysed to determine the use and understanding of nutrition labeling and its associated factors among free living elderly men and women aged ~60 years. Descriptive analysis and binary Logistic Regression were used to analyse the data. Results: A total of 4,898 respondents provided self-reported information on their use and understanding of nutrition labeling when they bought or received food. Use of nutrition labeling was higher among elderly men [61.9% (95% CI: 59.6-64.1)] than for women [36.6% (95% CI: 34.5-38.8)]. Nutrition labeling use was significantly associated with age, formal education, higher household income levels and marital status among both elderly men and women. Understanding of nutrition labeling among elderly men and women was 91.8% (95% CI: 90.1-93.2) and 89.7% (95% CI: 87.4-91.7) respectively and was significantly associated with formal education for both elderly men and women. Conclusion: Overall, the reading of nutrition labeling among Malaysian elderly is moderate. Elderly men and women with formal education were more likely to understand nutrition labeling. The importance of reading nutrition labels should be inculcated in consumers including older persons so that they choose foods that are nutritious and safe.

    Introduction: Osteoporosis is a major health problem worldwide. In Asia, few studies have measured knowledge, attitude and practices (KAP) of osteoporosis. This study aimed to determine the KAP of osteoporosis, including the main factors influencing attitude towards osteoporosis, and the relationship between osteoporosis knowledge, attitude, and practices among adults in Kuala Lumpur, Malaysia.
    Methods: A cross-sectional study via a self-administrated KAP questionnaire was carried out among 232 respondents aged 21 to 50 years in Kuala Lumpur. Random sampling was applied to select five districts in Kuala Lumpur, while convenient sampling was used for recruitment of apparently healthy subjects from community and institutional settings. The data were analysed using Mann-Whitney, Kruskal-Wallis, Chi-Square, Spearman Correlation and multiple logistic regression tests.
    Results: The findings indicate a moderate level of knowledge and attitude towards osteoporosis prevention with median scores of 51.6% and 68.6%, respectively. Osteoporosis knowledge varied significantly with gender, educational level and household income (p<0.05). Furthermore, attitude was significantly different in relation to educational level and household income. Based on the multiple logistic regression test, relatives and friends appeared to be the most significant factor influencing attitude (R=0.319, p<0.0001). Poor dietary and lifestyles practices were indicated, and a significant relationship was found between practice of weight-bearing activities and educational level (p<0.05). A significant correlation was found (ρ=0.348, p<0.0001) between knowledge and attitude, while no relationship was noted between knowledge and practice of weight-bearing activities or attitude and practice of weight-bearing activities.
    Conclusion: Knowledge played a significant role in affecting attitudes towards osteoporosis. However, understanding of osteoporosis is still at a moderate level. Friends and family were the most influential factor.

    Background Despite country’s tobacco control law, cigarette smoking by the young people and the magnitude of nicotine dependence among the school personnel is alarming.
    Objective To determine the prevalence of smoking and to examine the determinants of smoking behaviour among the secondary school teachers in Bangladesh.
    Methods A two-stage cluster sampling was used with a selection of schools on Probability Proportional to Enrolment (PPE) size followed by stratified random sampling of government and private schools and then all the teachers present on the day of the survey were selected for the study. The 66-item questionnaire included smoking behaviour, knowledge, attitude, second-hand smoking, tobacco free school policy, cessation, media advertisement and curriculum related topics. Seven additional questions were included to assess the socio-demographic characteristics of the teachers. Data analysis was performed using SPSS 17 software. A total of 60 schools were selected with school response rate of 98.3%. An anonymous self-administered questionnaire was filled in by all teachers present at the day of the survey. The sample consisted of 559 teachers with response rate of 99.5%.
    Results The prevalence of smoking was 17% (95% CI: 14%, 20.4). About half of the teachers (48.4%) smoke daily followed by 25.3% smoke 1-2 days in last 30 days. The mean duration smoking of was 13.7(95% CI: 11.6, 15.9) years. Logistic regression analysis revealed that male teachers smoke 37.46(95% CI: 5.078, 276.432) times higher than their female counterparts. The graduate teachers were 2.179(95% 1.209, 3.926) times more likely to be smoke than master’s degree holder teachers. Smoking by friends appeared to be the strongest predictor for teachers smoking behaviour (OR 4.789, 95% CI: 1.757, 13.050). However, no statistically significant association was found between type of school, second-hand smoking and curriculum related factors and smoking behaviour of the teachers (p>0.05).
    Conclusions Prevalence of smoking among the teachers is high in Bangladesh. Effective smoking prevention program should take into account within the dominant of socio-environmental influence to reduce smoking behaviour. The school curriculum items had less impact in preventing smoking behaviour.

    Introduction: This study seeks to identify the socio-demographic and behavioral characteristics of smokers (aged 18 and above), thus develop a predicting model for tobacco abstinence receiving cessation services for tobacco dependence at the Smoking Cessation Clinics (SCC) in government Primary Health Centers in Malaysia. These predictors would improve the effectiveness and efficiency of these clinics.
    Methods : Smokers who sought smoking cessation therapy at the SCCs from 1st January 2004 to 31st
    December 2004 were chosen randomly from clinic’s registries, and 254 smokers were recruited from 8 clinics chosen through stratified random sampling. Data analyses were performed with SPSS 12.0. 17.3% of smokers attending SCCs were able to quit smoking for at least six months.
    Results : Factors significantly contributing to quitting success were elderly smokers (above 40 years old), smoked for more than 15 years, smoked less than ten sticks per day, had a previous history of quitting attempt, self referral to the clinic, high confidence level, attended SCC at least four times, each counseling session lasted for at least 30 minutes and were satisfied with the clinic service. In logistic regression model, smokers aged 40 years and above were 6.7 times more successful to quit, high level of confidence were nine times more successful, smoked more than ten sticks per day were ten times less successful, self referred smokers were ten times more successful and attending for at least 30 minutes counseling session were 12 times more successful.
    Conclusion : This study concludes that more concerted effort is needed to approach various groups of target population and SCCs clinic services need to be improved.

    Cassava starch was used as feedstock for production of bioethanol by Saccharomyces cerevisiae. The cassava starch was hydrolyzed using commercial α-amylase and glucoamylase enzymes followed by a batch ethanol fermentation process using saccharified starch slurry. By using 110 g/L of reducing sugar from saccharified starch slurry, the ethanol yield was promising with maximum ethanol concentration of 20.6 g/L recorded after 55 hours of cultivation process. Three different models - the Logistic model, Luedeking-Piret-like equation and Gompertz equation - were used to characterize and explain the cell growth, reducing sugar consumption and production formation, respectively. The kinetic parameters were estimated by fitting the experimental data to the proposed models using non-linear regression analysis. The correlation coefficient r2 values for the Logistic model, Luedeking-Piret-like equation and the Gompertz equation were 0.994, 0.996 and 0.990, respectively. The high correlation coefficient values indicate that the proposed models were able to describe the ethanol fermentation process.

    Objective: School bullying in Malaysia is on the rise. While efforts are put together to combat the problem, the psychiatric aspect has been neglected. This is a cross-sectional study aimed to determine the association between the symptoms of ADHD and bully/victim problems among Malaysian sixthgraders attending primary schools in Kuala Lumpur.
    Methods: A total of 410 sixth-graders from seven randomly selected schools were assessed with regards to bully/victim problems and ADHD symptoms using self-reported questionnaires. Malaysian Bullying Questionnaire was used to rate bully/victim problems while ADHD symptoms were assessed using ConnersWells’ Adolescent Self-report Scale (CASS). Teachers and parents also assessed students’ ADHD symptoms using Conner’s Teachers Rating Scale (CTRS) and Conner’s Parents Rating Scale (CPRS), respectively.
    Results: Self-reported questionnaires showed that 61.2% of the children were involved in bully/victim problems. The ADHD symptoms were found significant in relation to bully/victim problems as tested by multiple logistic regression. Only students and parents reported significant ADHD symptoms among the bully/victim groups. The ADHD symptoms reported by students were significant among bullies(OR=0.59,CI=0.42-0.83, p
