Introduction: This cross-sectional study aimed to investigate relationships between diet quality assessed by Malay- sian Healthy Eating Index (HEI) and cardiometabolic risk factors in adolescents aged 13 years. Methods: 336 ado- lescents from various public secondary schools provided information on sociodemography and their anthropometric measurements including height (cm), weight (kg) and waist circumference (cm) were measured. Body mass index (BMI) was estimated thereafter. Dietary intakes assessed using a validated adolescent food frequency questionnaire (FFQ) was used to estimate Malaysian HEI. Biomarker parameters including lipid profile, fasting glucose, insulin and insulin resistance were also assessed. Associations of diet quality indicators to cardiometabolic risk factors were examined using regression models. Results: The overall diet quality of the adolescents was rather poor (49%), with a greater percentage of males were found to have low dietary quality score compared to females (56% vs. 39%; p
Introduction: Understanding childhood obesity becomes vital as a tremendous increase in the prevalence of over- weight/obesity among children and adolescents was observed. This cross-sectional study aimed to investigate the as- sociations between sociodemographic and psychological characteristics with body-mass-index-for-age (BAZ) among adolescents in Sibu, Sarawak. Methods: A total of 375 students (32.0% males and 68.0% females; 15-17 years old) at four randomly selected public secondary schools were recruited. A questionnaire on sociodemographic and psycho- logical characteristics (self-efficacy for physical activity, weight management, and nutrition, body discrepancy score, and sociocultural pressure to be thin) were used to gather information. Body weight and height were also assessed. Results: Around 18.6% respondents were found to be overweight/obese while nearly 5.0% were categorized as thin. In multiple linear regression, three significant predictors, namely body discrepancy score, being Iban (Reference: Chinese) and sociocultural pressure to be thin explained 45.1% of the variance in BMI-for-age z-score. Conclusion: Future interventions on adolescent body weight management should consider incorporating sociodemographic and psychological factors such as the development of positive body image, uniqueness in cultural value, and manage- ment of perceived sociocultural pressures to increase their effectiveness.
Approximately one in five children worldwide suffers from childhood malnutrition and its complications, including increased susceptibility to inflammation and infectious diseases. Due to improved early interventions, most of these children now survive early malnutrition, even in low-resource settings (LRS). However, many continue to exhibit neurodevelopmental deficits, including low IQ, poor school performance, and behavioral problems over their lifetimes. Most studies have relied on neuropsychological tests, school performance, and mental health and behavioral measures. Few studies, in contrast, have assessed brain structure and function, and to date, these have mainly relied on low-cost techniques, including electroencephalography (EEG) and evoked potentials (ERP). The use of more advanced methods of neuroimaging, including magnetic resonance imaging (MRI) and functional near-infrared spectroscopy (fNIRS), has been limited by cost factors and lack of availability of these technologies in developing countries, where malnutrition is nearly ubiquitous. This report summarizes the current state of knowledge and evidence gaps regarding childhood malnutrition and the study of its impact on neurodevelopment. It may help to inform the development of new strategies to improve the identification, classification, and treatment of neurodevelopmental disabilities in underserved populations at the highest risk for childhood malnutrition.
Introduction: Health care involves team work. Physicians, nurses, pharmacists and social workers need to work in collaboration to deliver quality health care. It is therefore vital that team work and collaboration are integrated into the training of medical students. In a medical school where interprofessional education has not been introduced, the preclinical students are trained in silos whereas the clinical students have interprofessional experiences in hospital and community centers. This study was conducted to explore medical student’s receptiveness for interprofessional education and to identify any differences in attitude among the preclinical and clinical year students. Methods: This study adopted a cross-sectional study design using purposive sampling technique at a private medical school in Malaysia. Participants completedthe standardized Readiness for inter-professional learning Scale and the data was analyzed. Results: 436 students witha mean age of 22 years participated in this study. Among them, 170 were from preclinical and 266 were from clinical years Both the groups scored high on team work while clinical students scored better than preclinical students in understanding professional identity and recognizing their roles. Conclusion: This study shows a readiness among medical students for IPE. Clinical year medical student’s attitude was similar to preclinical students.
Introduction: Findings from the National Health and Morbidity Survey III (MOH, 2008) indicate a 43.7% prevalence of physical inactivity among Malaysian adults. This sedentary lifestyle can also be observed among children and adolescents.
Methods: A cross-sectional study was conducted to determine factors associated with physical activity levels of four hundred, 13 year-old adolescents in Kuantan, Pahang. Data on socio-demographic, health-related, and psychosocial factors were collected using a self-administered questionnaire while physical activity level was assessed using the Physical Activity Questionnaire for Older Children (PAQ-C).
Results: About one-third of the respondents were in the low physical activity level category, 61.5% were in the moderate category and only 3.0% of the adolescents were in the high physical activity level category. Males were more physically active than females (χ2=23.667, p=0.0001) with female adolescents (45.1%) twice as likely as male adolescents (22.1%) to be in the low physical activity level category. The associations between physical activity level with socio-demographic and health-related factors, perception of weight status and body parts satisfaction were not significant. However, physical activity was found to be positively correlated with physical activity self-efficacy (r=0.496,p=0.0001), peer influence (r=0.468, p=0.0001), family influence (r=0.298, p=0.0001) and beliefs in physical activity outcomes (r=0.207, p=0.0001). Negative relationships were found between physical activity with depression (r=-0.116, p=0.021) and body size discrepancy (r=-0.143, p<0.01). Respondents who had a better perception of their current health status were more physically active (χ2=21.062, p=0.0001). Multivariate analyses for the prediction of physical activity showed that physical activity self-efficacy, sex and peer influence were the most significant contributors in explaining physical activity among adolescents.
Conclusion: Physical activity interventions should include psychosocial components as mediator variables in interventions designed to promote regular physical activity in adolescence.
Key words: Adolescents, physical activity, psychosocial factors, health-related factors and socio-demographic factors
INTRDUCTION: Obesity and chronic diseases have been increasing since the last few decades alongside rapid economic development in developed and developing countries. The alarming increase in the prevalence of childhood obesity had been shown by many epidemiological studies worldwide. The aims of this study were to determine the prevalence of overweight and obesity among Chinese school children in Kota Bharu, Kelantan, and to map the association between dietary practices and their nutritional status.
METHODS: A cross-sectional study was conducted on 278 school children aged 10 to 12 years old (144 boys and 134 girls) studying in a Chinese primary school in Kota Bharu.
RESULTS: The survey revealed that while only 1.4% (n=4) were overweight, 23.4% (n=65) of the children were obese. A total of 67.7% (n=44) of the obese children were boys. The overweight and obese children (n=70) were compared with a randomly selected group of normal weight children (n=70). Dietary assessment showed that protein, fat and total calorie intake were significantly higher among the overweight group (p<0.05). A significantly higher proportion of the normal weight children (85.7%) took breakfast daily or at least 4 days per week compared to the overweight groups (59.4%) (p<0.05).
CONCLUSION: The prevalence of obesity among school children in the study is a matter of concern. These findings may be useful in targeting programmes and strategies for prevention and intervention of childhood obesity.
The increasing prevalence of overweight and obesity among children has become a major public health problem in Malaysia. Parents play an important role in child feeding especially among younger children.
Eating patterns such as eating frequency, skipping of breakfast, and frequency of meals eaten away from home might influence school-going children's nutritional status, which will then influence their health and academic performance. This article reports the findings of a survey on the eating patterns of the school children and adolescents in Kuala Lumpur. A total of 3620 school children studying in Primary 5, Secondary 2 and Secondary 4 were selected using multi-stage sampling. The students were surveyed using a pre-tested questionnaire while their weights and heights were measured in the field. It was found that 19.9% skipped at least one meal a day with the youngest group having the lowest prevalence. The most frequently missed meal is breakfast (12.6%) followed by lunch (6.7%) and dinner (4.4%). The school is an important provider of breakfast and lunch for the students. As the students' age increased, the prevalence of eating breakfast and lunch in school increased. The youngest age group had the highest prevalence of snacking and taking of nutritional supplements (p<0.05). Fast food and local hawker food were also consumed by about 60-70% of the students. Logistic regression analysis showed that skipping of breakfast is significantly associated with age, sex, BMI and taking of nutritional supplements. Promotion of healthy eating should be targeted at students in primary and secondary schools as they tend to depend on outside food.
This study assessed the effectiveness of a biorational control approach using 2% hydramethylnon gel bait on German cockroaches, Blattella germanica (L.) in some residential and hospital buildings in South Western Iran. In total, three buildings consisting of 150 apartment units and 101 hospital units were monitored weekly via sticky trap for German cockroach infestations over a period of eight months. These infested units were randomly subjected to intervention and control treatments. Pamphlets and posters were provided and lectures were given to support the educational programmes as a tactic of the biorational system. Survey on cockroach index for intervention units showed 67-94% recovery to achieve clean level of infestation for intervention units of the residential buildings and 83% for the hospital. Mean percentage reductions for treatment groups throughout the 15-week treatment period were 76.8% for the residential buildings and 88.1% for the hospital, showing significant differences compared to the control groups. Linear regression of infestation rates were recorded weekly after treatment and their negative slope for treatment groups substantiated significant reductions for interventions. The results of this study showed that biorational control method, using gel bait, educational programmes and sanitation, is an effective way to manage German cockroach infestation.
This is a cross-sectional study conducted from January to September 2004 in a group of school children aged 8 -10 years old. The schools and study subjects were selected using stratified systematic sampling technique. A total of 44 schools and 1100 subjects were selected from schools with iodinator and schools without iodinator. Samples collected were spot urine and drinking water. Dietary and iodised water consumption data were obtained from interviews. A total of 931 subjects (84.6%) responded; 558 (50.7%) from schools with iodinator and 373 (33.9%) from schools without iodinator. Results showed that in more than half (53.8%) of the schools with iodinators, mean water iodine level was below 25 microg/L. The study population in Terengganu was found to be mildly iodine deficient with an overall median urine iodine concentration (uIC) of 74 microg/L. Based on WHO criteria, 4.1% with uIC <20 microg/L (severe), 19.5% with uIC between 20-49 microg/L (moderate), 49.2% with uIC between 50-99 microg/L (mild) and 27.2% was iodine sufficient with uIC >100 microg/L. Majority of the study subjects were found to have high seafood intake (> 90%) and low in goitrogen food intake. This study suggests water iodinator system may not be a suitable method of supplying iodine and an alternative is needed in order to eradicate the iodine deficiency problem seen in some parts of Malaysia.
Dietary habits and choice of food influences nutritional status of adolescence. Malnutrition have been associated with adolescents' dietary habits that may predispose to chronic disease during their adulthood. The aim of this study is to determine the association between food habit and nutritional status of adolescents. In the baseline study, a total of 924 students from 10 secondary schools were randomly selected from a total of 62 secondary schools in Kuala Lumpur. The students were assessed on various dietary components including food habits using a structured questionnaire as well as for anthropometry measurements. All data were analyzed using SPSS 23. The prevalence of obesity was significantly higher among males compared to females (16.4% vs. 8.4%, X2=25.42, p<0.001). Food habit exhibits an inversed association with z-score of body mass index for age (β=-0.107, 95% CI=-0.053, -0.013), especially via food habits such as often eat dinner (r=-0.102, p=0.002), often have breakfast before school (r=-0.100, p=0.002), often eat cake or dessert at meal (r=-0.110, p=0.001), often drink eight glasses of water (r=0.132, p<0.001), often eat food from school canteen (r=-0.071, p=0.031) and often bring own snack from home (r=-0.112, p=0.001). This study suggested that the type of food and timing of meal should be considered to prevent obesity among adolescents.
Background: Mothers play an important role in preventing fluorosis due to inadvertent swallowing of fluoridated toothpaste and enhancing the effectiveness of toothbrushing amongst preschool children through proper supervision.
Aim: To investigate the knowledge of mothers with regards to the benefits and risks of fluoride toothpaste usage among preschool children and to assess the level of parental supervision during toothbrushing. In additional, we wish to investigate the toothpaste purchasing behaviour of mothers in relation to brand, price, flavour, fluoride content and the influence of advertisement.
Methodology: Cross-sectional study of a representative random sample of 373 mothers of 5-6 year old preschool children through self-administered questionnaires.
Result: The response rate was 90.3% (337). The majority (61.7%) of the mothers reported that the amount of toothpaste their children used was half-length. Most mothers (70.6%) claimed they usually apply toothpaste for their child. About one-half (50.4%) reported the children applied the toothpaste themselves. Only 41.2% of the respondents supervised their children every time during toothbrushing. The mean age at which the child started brushing and using toothpaste was about 34 months (S.D. 14.9) and 37 months (S.D.14.8) respectively. Almost all (95.8%) reported that their children rinsed their mouth after toothbrushing. The mothers’ choice of toothpaste for their child was influence by brand (91.4%), flavour (91.4%) and fluoride content (84.6%) with price being the least of the factors. The majority of the respondents (82.7%) had average to good overall knowledge scores. There was significant association (P=0.034) between the level of education of the mothers and their level of knowledge on fluoride toothpaste usage.
Conclusion: Future oral health messages for preschool children and mothers in Perlis should target areas found lacking in terms of knowledge and practices with regards to fluoride toothpaste usage. This includes regular supervision of preschool children during toothbrushing by parents and using only a small amount of toothpaste for young children.
Exposure to secondhand smoke has consistently been linked to adverse health effects in children, including reduced lung function and various respiratory diseases. There is also increasing evidence that secondhand smoke exposure is associated with cognitive impairment and behavioral problems in children, This cross sectional study was done on 795 chiildren to determine the association between secondhand smoke exposure and peak expiratory flow rate (PEFR) and cognitive performance among the primary school children in Kota Bharu Kelantan. A questionnaire was used to obtain information on socio-demography and smoking status of the household. The PEER was measured using a child Mini Wright peak expiratory flow meter while cognitive performance was assessed by four subtests of Weschler Intelligence Scale For Children (WISC III). Data analysis was done using SPSS version 11. Children were classified as exposed to secondhand smoke when at least one househoH member smoked. There were 442 (55 .6%) children exposed to secondhand smoke at home. The mean (SD) PEFR for unexposed and exposed children were 266.18 (60.80) l/min and 266 .06 (57. 70) l/min respectively, The mean (SD) scores for Digit Span Forward, Digit Span Backward Coding and Arithmetic in unexposed chiMren were 6.84 (1.80), 4.Z7(1.68), 45.25 (9,99) and 8.04 (1.04) respectively. The mean (SD) scores for exposed children were 6.73 (1 .77). 4.07 (l .65), 45.1 I (1 I ,03) and 8.13 (1 .00) respectively. Multivariate analysis of variance showed no signincant dijference in the PEFR (p=O.816) and the cognitive scores between exposed and unexposed primary school children in Kota Bharu, Kelantan
Background: In Malaysia, the prevalence of hypertension amongst adults aged 30 years and above has increased from 32.9% in 1996 to 40.5% in 2004 and to 42.6% in 2006. Information on the prevalence of hypertension among adolescents is lacking.
Objective: to determine the prevalence of hypertension among Malay secondary school students in Putrajaya.
Methods: A cross sectional study was carried out in Putrajaya, Malaysia. The sampling frame consisted of a list of all the 12 secondary schools in Putrajaya. Three schools were selected using table of random numbers. All Malay students aged 13 years old to 17 years old from the three selected school students were included in the study. Blood pressure was measured after the respondents had rested for at least 5 minutes using a standard mercury sphygmomanometer. Three blood pressure measurements were taken for each respondent. Systolic blood pressure [SBP] was defined as the average of three SBP readings and diastolic blood pressure [DBP] was defined as the average of three DBP readings. Data was analyzed using SPSS 18.
Results: The overall mean SBP and DBP were 108.9 mmHg and 63.2 mmHg respectively. The prevalence of pre-hypertension and hypertension among the male was 16.2% and 12.9% respectively as compared to 5.8% and 10.2% respectively in the females. The overall prevalence of prehypertension and hypertension was 11.1% and 11.6% respectively. The prevalence increased with age (p<0.05). There was a significant positive correlation between BMI and SBP (r = 0.52, r2 = 0.27, p= 0.001) and BMI and DBP (r = 0.38, r2 = 0.15, p= 0.001). The mean SBP was significantly higher in males (111.7 mmHg) as compared to 106 mmHg in females (p<0.001). The mean DBP in males (63.5 mmHg) was slightly higher as compared to 62.9 mmHg in females but the difference was not significant.
Conclusions: Prevalence of hypertension and pre-hypertension is high. There is an urgent need for implementation of a comprehensive CVD prevention program and routine blood pressure measurements should be taken in school children to improve the detection, prevention and treatment of hypertension

The aims of this study were to determine the prevalence and factors that influenced smoking behaviours among male adolescents in Kuantan, Pahang. A cross-sectional study was conducted among the form four male students in Kuantan District. Three hundred and twenty three students were randomly selected from eight secondary schools. A self-administered questionnaire was distributed to all the respondents. Almost half of the sample was smokers (45.8%) and half of them were Malays (53.1%). Students whose parents had lower level of occupation were more likely to smoke (58.8%). Among smokers, 34.5% of them smoked since primary school and a majority (91.7%) smoked 10 or less cigarettes per day. Half of them (53.4%) reported that they bought loose cigarettes and most of them used their school pocket money to purchase the cigarettes (81.7%). From the multivariate analysis, it was found that Non-Science Stream classes (OR=3.92, 95% CI= 2.10, 7.32), peers' smoking (OR=6.07, 95% CI= 2.32, 15.92), and attitude towards smoking (OR= 21.93, 95% CI= 9.71,49.51) were significantly associated with smoking habit. The prevalence of smoking among male adolescents was considerably high'in this population. It is recommended that antismoking activities in school be carried out regularly and should involve an active participation from the adolescents themselves since peers have great influence on smoking habits.
Overweight during adolescence has many psychological consequences and low self·esteem is the immediate detrimental effect observed. Adolescents with low self»esteem are at risk for many emotional and behavioural disorders while high self-esteem adolescents experience an incremental improvement in their quality of life. The objective of this study was to compare seh'-esteem between overweight and non-overweight Malay adolescents in Kota Bharu, Kelantan. A cross-sectional study was conducted between January to ]une 2005 among 1364 students selected from ten co-educational government secondary schools in Kota Bharu using stratified multistage cluster sampling. A set of guided self-administered questionnaire which included a Malaysian version of Rosenberg Self-Esteem Scale and Body Mass Index measurement was used. Data was entered using SPSS 12.0 and analysed using STATA 8. O. The prevalence of overweight among secondary school students in Kota Bharu was 12.5% and there was no significant difference in self-esteem between overweight and non-overweight students. However, the findings may not be generalized to out-of-school youth and other ethnic groups in this country. Infomation on other modifers, such as parental acceptance or lack of concern regarding the child’ obesity was not elicited in this study. It is an important protective factor for self-esteem and need to be included in future studies.
Mental health difficulties in children are often missed or dismissed. Adults too are often wary of bringing their children to such a facility. This paper is a descriptive study of a child mental health service utilization in Kuala Lumpur. Methods: The cases consisted of new cases from the month of January to December 2007 who attended the Psychiatry Adolescent and Child (PAC) Unit, University Malaya Medical Center (UMMC). Results: The children presented with a range of development, academic, behavior and emotional difficulties. There were 373 new cases of which the highest number of children were in the primary school-going age group (54.7%) and males (65.4%). Sixty percent of the cases had one single diagnosis. Children with Attention Deficit Hyperactive Disorder (ADHD) were the highest disorder seen in the single diagnosis group (27.3%) as well as in those with more than one diagnosis (61.5%). Primary support group difficulties were the most common co-morbid condition noted. Conclusion: It is essential that extensive screening of children and their families be done to detect family difficulties and co- morbid conditions, which would be necessary for favorable outcomes to be met.
The National HPV Immunization Programme, which offers free human papillomavirus (HPV) vaccines to teenaged female students, was launched in Malaysia in 2010. HPV vaccination paired with adequate knowledge about HPV infection provides the best protection against cervical cancer. To identify the level of knowledge and the health beliefs towards HPV and the HPV vaccine among HPV-vaccinated female students in Malaysia. A nationwide cross-sectional survey among 14 years old female students who had received three doses of the HPV vaccine was conducted in 32 randomly selected schools from 13 states and 3 federal territories in Malaysia between February 2013 and April 2013. Among 2482 respondents, knowledge about HPV infection and the HPV vaccine was extremely poor. The mean total knowledge score was only 3.56 (SD ± 1.76), out of a possible score of 10. The majority of respondents were unaware that vaccinating boys with HPV can help protect girls against HPV infection (91.6%), HPV cannot be cured (81.6%) and that HPV is a sexually transmitted infection (70.3%). Most of the respondents had the misconception that only females get HPV (95.1%), and that the HPV vaccine eliminates the need for Pap smear tests (68.3%). Most respondents (91.6%) believed that they would not get an HPV infection. Almost half of the respondents (42.9%) held the misconception that HPV infection could not lead to serious illness. Findings revealed poor knowledge about both HPV and the HPV vaccine, low perceived susceptibility to HPV infection and misinformation about HPV infection among HPV-vaccinated girls. Therefore, it is essential to increase the knowledge and awareness of health risks regarding HPV infection among teenaged girls who have received the HPV vaccine.
Few health studies exist on dampness and mould in schools in the tropics. We studied associations between fraction of exhaled nitric oxide (FeNO), respiratory symptoms and airway infections among students and dampness and fungal DNA in schools in Malaysia. A total of 368 randomly selected students from 32 classrooms in 8 secondary schools in Penang, Malaysia, participated (58% participation rate). Information on current respiratory symptoms and the home environment was collected by a standardised questionnaire. FeNO was measured by NIOX MINO (50ml/min). The classrooms were inspected and dust was collected by vacuuming on special filters and was analysed for five fungal DNA sequences by quantitative PCR. Linear mixed models and 3-level multiple logistic regression (school, classroom, student) were applied adjusting for demographic data and the home environment. Totally 10.3% reported doctor's diagnosed asthma, 15.1% current wheeze, 12.4% current asthma, 37.3% daytime breathlessness, 10.2% nocturnal breathlessness, 38.9% airway infections and 15.5% had pollen or furry pet allergy. The geometric mean of FeNO was 19.9ppb and 45% had elevated FeNO (>20ppb). Boys had higher levels of FeNO. Chinese had less daytime breathlessness than Malay (OR=0.30: p<0.001). Indoor carbon dioxide levels were low (380-720ppm). Dampness was observed in 18% of the classrooms and was associated with respiratory infections (OR=3.70; 95% CI 1.14-12.1) and FeNO (p=0.04). Aspergillus versicolor DNA was detected in 67% of the classrooms. Higher numbers of Aspergillus versicolor DNA in classroom dust were associated with wheeze (p=0.006), current asthma (p=0.002), respiratory infections (p=0.005) and elevated FeNO levels (p=0.02). In conclusion, respiratory symptoms were common among the students and the high FeNO levels indicate ongoing airway inflammation. Building dampness and the mould Aspergillus versicolor in schools in Malaysia can be risk factors for impaired respiratory health among the students.
Introduction: The academic life of medical students can be considered as psychological toxic. About half of United States medical students experience burnout and more than 25% experience depression. This study aimed to determine the prevalence of burnout among medical students in a Malaysian medical school and its associated factors.
Methods: This is a cross sectional study of 452 medical students from Universiti Sains Malaysia (USM). Copenhagen Burnout Inventory was distributed via Google Forms through Facebook Messenger. Ethical approval was obtained from the Human Research Ethics Committee USM. Data were collected via Google Sheets. Each respondent only submitted one Google Form as no resubmission link was provided once completed Google Form was submitted.
Result: The prevalence of burnout among USM medical students was 67.9%. Personal burnout was the highest (81.6%), followed by work-related burnout (73.7%) and client-related burnout (68.6%). The analysis showed that regardless of year of study, gender and ethnicity (all P > 0.05), USM medical students were vulnerable to burnout.
Conclusion: The prevalence of burnout among USM medical students was high and the most prevalent type of burnout was personal burnout. Therefore, burnout among medical students should be a concern and must be addressed to prevent subsequent unwanted consequences.
