Indoor air quality (IAQ) has become a major concern nowadays because of the universality of exposure and its potential negative impact on human health especially on children. This study is intended to explore the association between IAQ and the respiratory health among preschool children in urban and suburban area. A cross-sectional comparative study was carried out among Malay preschool children in urban (N= 60, Puchong) and suburban (N=60, Hulu Langat) areas. An indoor air quality assessment was conducted in 12 preschools and 60 houses which include parameters of PM2.5, PM10, VOCs, mold, bacteria, Gram-negative bacteria and physical parameters. A set of standardized questionnaire was distributed to obtain respondents’ background information, exposure history and respiratory health symptoms. Spirometry test was carried out and the data obtained were analyzed to determine the lung function of the respondents. There was a significant difference between IAQ in urban and suburban preschools for all parameters measured (p<0.05). Most of the pollutants were significantly associated with respiratory health symptoms. There was a significant association between the level of indoor pollutants with the lung function abnormalities among the respondents. Even though this study is the first to take Gram-negative bacteria as an indoor air pollutant, the finding also shows that there is a significant association between exposure of Gram-negative bacteria with lung function impairment and higher reported respiratory symptoms among the respondents. The finding concluded that exposures to indoor air pollutants, especially PM2.5 increases the risk of getting lung function abnormality and respiratory health symptoms among respondents.
Waste and by-products form palm oil trees are versatile and can be used as biomass fuel, but the processes of producing electricity by using low pressure boilers are causing air pollution. The objective of this study is to determine the association between PM10 and PM2.5 exposure with respiratory symptoms and lung function among children living near to palm oil mill. A cross- Sectional comparative study was carried out among school children at Dengkil and Kerling. Questionnaires adopted from ATS-DLD-78-C were distributed to the respondents’ parents. PM10 and PM2.5 was measured. Lung function of the respondents was evaluated by using Chest Graph Spirometer; results were compared with standards of lung function, by ATS (1991). There was a significant difference for Mean±SD PM10 and PM2.5 in studied and comparative area, (p
A qualitative research was carried out in Besut and Kuala Terengganu to identyy adolescents’ health problems and needs jiom adolescent perspective, and to establish a priority area in the development of Adolescent Health Clinic in the district. A total of 61 adolescents were selected and divided into four groups and stratified according to age, 13-15 years old and 16 - 17 years old. Generally all participants wished to live in an environment free hom negative health risk factors. The obstacles they perceived were mainly related to lack of care or too much control by their parents. Some of them perceived that their parents in general had inadequate knowledge and skills on parenting. Among local behavioural problems mentioned were loafing, running away from home, vandalism, school absenteeism, aggressive behaviour, substance abuse, pre-marital sexual activities, "bohsia", “bohjan" and even involvement in crimes. More than hah' agreed that counselling service is important for adolescents, and it should be made available in the community preferably outside the schools. They perceived an adolescent friendly health clinic concept as an important concept that should be introduced. To them adolescent friendly health clinic is a clinic run by professionals who are knowledgeable, caring, good listeners, non—judgemental, and who exercise confidentiality. The clinic preferably should be situated in a location which is away from the present health facilities to avoid the image of a place for sick people. Clinic hours preferably during weekends, should provide appropriate technologies and situated in a comfortable ambience. Adolescent participation in the clinic was also mentioned as an important entity for adolescent friendly health services.
Diabetic retinopathy (DR) may result in progressive visual impairment and blindness which affects the diabetic patients‟ morbidity and quality of life significantly. The objective of this study was to determine the proportions and prognostic factors of DR severity among Type 2 diabetes mellitus patients. A cross sectional study was conducted at the Ophthalmology Clinic in a tertiary hospital using the medical record database from 2005 to 2011. A total of 216DR patients were randomly selected. The study outcome was DR severity which was classified into four grading based on the International Clinical Diabetic Retinopathy Scale. Descriptive statistics and Ordinal Logistic Regression were applied using Stata SE/11. The mean (SD) age of DR
in this study was 56.06 (9.98) years old with almost equal sex ratio. Proportion of mild non proliferative diabetic retinopathy (NPDR) was 48.6% (95% CI: 40.0, 60.0), moderate NPDR was 28.2% (95%CI: 22.0, 40.0), severe NPDR was 6.9% (95% CI: 4.0, 11.0) and proliferative diabetic retinopathy (PDR) was 16.2% (95%CI: 10.0, 22.0). Diabetic patients that suffered from diabetes mellitus for more than 10 years, having nephropathy, every increased of HbA1c by 1% and higher total cholesterol were at increased risk of worsening DR.

An investigation was undertaken 0f a malaria outbreak in Felda Neram 1 in the district of Kemaman,
Terengganu. Thirty-eight malaria cases of Plasmodium falciparum with one death were reported from that locality. The outbreak peaked between the epidemiological week of 42 and 44. A total of 2300 persons were surveyed with population coverage of 90%. Overall Slide Positive Rate was 1.5%. Out of 38 cases, 19 were Malays and the rest were Indonesian workers. Seventy-nine percent (30/38) had a history of fever within nine weeks prior to the survey. Thirty persons were found to be febrile on the.date of the survey of which 42% (14/30) were smears positive. Blood smears showed 65.7% (25/38) had an asexual parasitemia and 34.2% (13/38) cases were gametocytaemic. The males0”emales ratio was 1:7. Younger age groups were more ajfected. All patients were given radical malaria treatment. F orty-three percent (16/38) had a second course of radical treatment. The outbreak was caused by the re-entry of an Indonesian worker with malaria to the locality. Factors such as delayed detection and notyication and inadequate surveillance were instrumental for the outbreak.
Ergonomic is important in classroom. Sitting for protracted period in class may lead students to develop musculoskeletal disorders. Their physical health and performance in the class may increase by designing school furniture that match with human body. In Malaysia, there is a lack of ergonomic assessment for school environment especially in urban areas. The aim of this study is to determine the mismatch between the furniture dimension and anthropometric parameters among primary school children in Putrajaya. This is a cross-sectional study which involved 100, Year 1 and Year 6 primary school students randomly selected in Putrajaya. Five anthropometric measurements (popliteal height, buttock popliteal length, elbow height, shoulder height (sitting), hip breadth) as well as five furniture dimensions (seat height, seat depth, seat width, backrest height and seat to desk height) were measured. Instrument used is Martin type anthropometer set, SECA body meter, and SECA weighing scale. Calculation for determining mismatch between the furniture and anthropometric measures were calculated using a standard mismatch formula. There was 100% mismatch for seat height, seat depth, and seat to seat to desk height for Year 1. As for Year 6, mismatch was reported 100% for backrest height and seat to desk height. There were significance difference for parameters of popliteal height between Year 1 and Year 6 and between male and female of Year 1. There was a presence of mismatch between furniture dimension and children anthropometric measurement. Proposed dimension of furniture shows decrease in percentage of mismatch for the most parameter of anthropometric measurement.
Solid waste collection has been a major challenge for local council Municipal workers in urban areas where the population is growing rapidly and the need for local councils to ensure they provide service to clear solid waste in a timely manner without disrupting the existing system. This case study is a review of awareness of health and safety among municipal workers on solid waste collection. The study is an examination of such awareness in Malaysia which involves the Petaling Jaya City Council in the state of Selangor. We review the operating system of the Petaling Jaya City Council and the risks which are being exposed to the municipal workers in their daily operations. Health and Safety of municipal workers in the areas of public health, safety, and industrial hygiene has been a concern for a long time. In most cases the majority of municipal workers exposed are from the contractual aspect of outsourced labour. It is important to understand how large the area of a solid waste is and to identify, evaluate, and eliminate or control risks and hazards across the operation zone of the municipal workers which involves environmental and occupational demands. The data we find provides the latest perspectives on topics of widespread concern such contractors management, ergonomic safety, confined space, motor vehicle safety, machinery safety, fall hazard safety, electrical safety and emergency response. Management of legal requirements is also discovered to be important to ensure any organization conducting business is not in violation of any law, and if there is a change of process how is this being addressed. Finally, we look at the control measures needed to support a operation on a large scale where it will not endanger the health and safety of municipal workers when they are involved in solid waste management. The recommendation we have based on the review are to ensure there is a holistic approach and systems in place to address all the concerns that will be faced by the local municipal council in their daily operations and responsibilities at every level of the organization. Conclusion: Research material and data related to this area is limited and we hope future holistic research can be conducted to future enhance the study of health and safety effecting the municipal workers. Health and Safety management system and procedures are the key elements in ensuring a successful organization.
Paddy cultivation is one of the widely planted crop in Malaysia. The growth of agricultural activity leads to the use of Organophosphate pesticide to protect the crop. This study is to determine the relationship between the levels of blood cholinesterase with the performance of motor coordination of children living in paddy farming area in Tanjung Karang, Selangor. This cross sectional study was conducted among 683 children from four schools in an agricultural area. Majority of the children have at a family member worked as farmer and was involved with pesticides. A set of questionnaire on the was given to the children to be filled by their parents. To measure their exposure to pesticide, blood cholinesterase levels were measured. Blood samples were taken through finger prick technique and were then analysed using LOVIBOND 412870 AF287. The children were administered with motor-coordination performance test using WHO Neurobehavioral Core Test Battery and McCarthy Learning Ability Scale. Young group children (6-85 years) showed a mean score of 56.66 in motor-coordination test while older group children (10-11)= years) scored a mean of 45.37. There was a significant relationship between blood cholinesterase level and motor coordination performance among the young-group children (r=0.215, p<0.001) and the older-group children (r=0.106, p=0.049). Based on the Linear Regression test results, total household income of family, and mode of transport used were found to have significant relationship with blood cholinesterase level of children in both groups. In addition, blood cholinesterase level and mothers’ occupation were found to have significant relationship with the motor-coordination performance of all children.
We compared the determinant factors of depression; among faculties in university, among junior and senior students, and gender differences among representative samples of faculties in university. Centre for Epidemiological Studies Depression (CES-D) consisting for 20 questions was used to assess the status of well-being of students. A total of 240 students participated and completed the assessment forms. The results were then compared and analyzed using the IBM SPSS Statistics version 21. There was no effect of faculty on depression (p=0.854). The association between year of study and depression was not statistically significant (p≥0.05). Likewise, the association between gender and depression was statistically not significant (p≥0.05). The study revealed absence of statistically significant effect of faculty on depression. It was also found that gender and depression as well as year of study and depression were not statistically significant.
Anthropometric Test Devices (ATDs) of different nominal percentile values have long been used as human surrogates in automotive crash testing. The Hybrid III family, which is one of the widely used ATDs in frontal crash test, was designed based on the anthropometry dimensions of US adults. Thus, this paper aims to assess the anthropometric differences between Malaysian adults and Hybrid III dummies in terms of 5th percentile (small female), 50th percentile (midsize male) and 95th percentile (large male). A series of anthropometric parameters of Malaysian adults was obtained from a database of 1321 subjects with 708 males and 613 females. The results revealed that the current midsize male population differs from the ATD’s statures and body weights by about 35 and 40 percentile points, respectively. This demonstrates that the current ATDs are not truly representative of the current Malaysian adults, which may potentially lead to different injury responses in road traffic crashes. Thus, car manufacturers may as well consider this discrepancy issue in developing their future models especially with regards to safety.
Lane Change Assistance (LCA) system in cars can potentially mitigate blind spot related crashes; but its effectiveness
largely depends on driver acceptance and proper use. Although still in early stages, the volume of cars equipped with
LCA system is expected torise in the near future as the technology has been considered in the New Car Assessment
Program for Southeast Asian Countries (ASEAN NCAP) 2017 Rating Scheme. Therefore, this study is initiated to assess
user acceptance of and experience with LCA-equipped cars. Self-administered questionnaires were distributed to
owners of LCA-equipped cars at selected service centres in the Klang Valley from November 2016 to February 2017.
From a total of 276 valid responses, results revealed that most owners greatly considered LCA system when
purchasing their cars and agreed that the systems had positively altered their driving behaviours i.e. regularly using
the turn signal and checking the side mirrors. Nevertheless, about 20% of the respondents stated theirannoyance and
distraction by the LCA systems due to unnecessary warnings from various sources, aside from getting too many
warnings during traffic congestion. The study findings provide some practical implications that can aid the industry
and relevant stakeholders in gauging the issue and actual situations concerning the use of LCA system in Malaysia.
Surprisingly little was known about the importance of touch in life which was placed at a lower emphasis than the rest-namely visual, auditory, olfactory sense and etc. This writing aimed to decipher the significances of interpersonal touch, its culture, practices, barriers and challenges, which were then conveyed to the public as a form of health promotion. Methodology includes narrative review where the suitable literatures used were searched using ScienceDirect database under the keywords of “Interpersonal Touch”, “Oxytocin” and “Touch”. In this review, we have highlighted some of the most critical points which should have been promoted to the public. For example, touch satisfies individual psychosomatic and psychosocial needs. It forms a non-verbal communication culture which interacts about emotions, trust, compliance and more. Furthermore, it has been linked to the secretion of multifunctional bioactive chemical-oxytocin which was well-known in its therapeutic advantages for a wide range of commonest chronic diseases and social ills. Although some dysfunctional consequences may be resulted, incorporating genuine interpersonal touch into today’s efforts is undeniably viewed as a good option in solving many social problems.
Obesity is a major health concern and the growing rate raises important issues specific to concurrent rise of the related diseases especially hypertension. This study aimed to determine the relationship between hypertension and obesity based on body mass index and waist circumference besides relevant sociodemographic factors according to gender specific analysis. The analysis is important to determine in depth insight of two genders. This cross-sectional study was conducted among community in Tanjung Karang, Selangor, Malaysia in 2009 and included a total of 439 male and 668 female respondents aged 18-59 years old. Data was collected by interview-guided questionnaire and anthropometric measurements. SPSS version 21.0 was used for analysis of the relationship between socio demographic factors, smoking, body mass index and waist circumference with hypertension. Finally logistic regression analysis was used to assess the predictors of hypertension according to gender. The prevalence of hypertension was 25.5% in males and 23.1% in females, giving a total of 24%. Significantly higher prevalence of hypertension was found in overweight and obese categories (42.2% and 60.5% in males; 39.5% and 48.9% in females). Those with abdominal obesity also had significantly greater risk in having hypertension (41.6% in males and 33.2% in females). The logistic regression analysis indicated that age, high BMI and abdominal obesity were significantly associated with hypertension in women, and on the other hand age and BMI only for men. Both obesity and abdominal obesity are significantly important predictors of hypertension in females but BMI obesity only in males. Effective weight management strategies targeting obese people and abdominally obese women should be implemented in order to prevent hypertension and related cardiovascular diseases.
Discomfort and pain issue at the body part are common complaints reported by car drivers. It is due to driving task
require physical demands and need to maintain and adapt several postures in a constrained space while controlling
the car. Hence, this study aims to determine the pattern of shoulder activation muscle consisting of the Trapezius
muscle in two different driving posture. Respondents were required to grasp the steering wheel at 8 and 4 hand
position. The Surface Electromyography was used to get the reading for left muscle’s Trapezius Descendent (TD) at
two different positions; i) closest distant from steering wheel and ii) far distant from the steering wheel. Then,
Temporal Analysis was used to evaluate the pattern of the driving action. From the experiment, it shows the
different value of muscle activation occurred while driving according to turning action. The far seated position
depicted greater activation on driving action compared to the closer seated to the steering wheel. In conclusion, the
driving posture effects the activation of shoulder and arm’s muscles as early as after 20 seconds of driving activity.
Hence, choosing the correct driving posture allowed a comfortable driving environment for the driver.
Indoor air quality is an essential aspect for occupational health including in a densely populated university. This study aimed to assess the indoor airborne microorganisms via biochemical and molecular approaches in five enclosed workplaces, and their resistance towards six commonly used antibiotics. Cfu/dm2/h for five enclosed workplaces was determined using settle plate technique with 1/1/1 scheme and Gram staining was performed for all pure strains isolated. Two strains with the highest count and with different morphologies were identified using biochemical test as well as 16S rRNA amplification and direct sequencing. Minimum inhibitory concentration for antibiotics was carried out for these two strains. In this study, 27 microbial strains with different morphologies were obtained from all workplaces and 2 strains with the highest count were strain J in café and strain M in library, which were identified as Bacillus cereus and Staphylococcus cohnii, respectively. Both of them were highly susceptible to ampicillin and tetracycline. With resistance up to 0.78 µg/mL; B. cereus was less sensitive to kanamycin and neomycin whereas S. cohnii was less sensitive to streptomycin. In conclusion, antibiotics resistant B. cereus and S. cohnii were two of the microorganisms showing the most abundance in the café and library of a Malaysian public university, respectively. This study may serve as the baseline for the prescriptions of antibiotics to airborne microbial related infections especially to the community in the university who seek for medical treatments; particularly for respiratory and digestive infections which often associated with indoor microenvironment.
The main objective of the study was to determine the oral health status and possible factors influencing oral hygiene in the institutionalized elderly in Sabah. A cross sectional study in all four institutions for the elderly in QM ii Sabah was conducted using oral examination and interview/questionnaires. Qualitative assessment using Focus Group Discussion was carried out in the caregivers of the institutions. Plaque score was used to assess oral hygiene status. A total of 94.0% of inmates were above 55 years old. There were 13.4 % non-respondents in the total sample of 284. Of the n0n—respondents, 42.4 % had mental disorders and this was statistically signnicant. Of those who responded 34.6% had good 33.3% fair and 32.1% poor oral hygiene. 33.5% were completely edentulous, 86.4% had gingivitis which required scaling, 22.0% had decayed teeth and 54.9% required extraction. Gingivitis, decayed teeth and number of teeth for extraction were signwcantly associated with poor oral hygiene. 14.2% had at least one type of oral disease. Dental abscess was the most common muco»cutaneous lesion found. Mental disorders showed a trend towards poor oral hygiene and this was statistically signyicant. Although 40.8% had physical handicap, 23.3% visual impairment and 8.2% hearing impairment, there was no significant association with oral hygiene status. In conclusion, oral health status of the population is poor and treatment needs are high. Although there was high objective need for oral care (88.6%), perceived need was low (32.0%).
The aim of this study was to determine the pattern of health care utilization amongst the rural community and the prevalence of complementary health care in Kampung Giching, Sepang, Selangor, A cross sectional study was conducted in 2001. Out of the 154 respondents selected by universal sampling, only 131 completed the questionnaires giving a response rate of 85.1 %. The
respondents were asked to recall the presence of any illness during the past 6 months and their use of health care, Twenty-four respondents claimed to be healthy without having any illness (18,3%), 33 respondents (25,2%) reported that they had chronic illnesses, while the rest (n=74) reported having acute illnesses. There were 54.2% of the respondents admitted trying self-medication and 10.3% seelced traditional medication for their respective illnesses. Among the self»medicated respondents, 48,3% used modem medicine, 48 .3% used traditional medicine, 1.7% used both modern and traditional medicines and 1 .7% respondent used home remedies. The results of this study show that both modern and traditional practitioners play important roles in giving information on self-medication, These practitioners as well as the public should be advised on the benejits and side»e]j"ects of both types of medication (modern and traditional).
Misuse of alcohol among adolescents, particularly schoolchildren has become one of the public health concerns in Malaysia due to its serious effects and an increased risk of alcohol related injuries, especially motor vehicle injuries. This is the most common type of youthful fatal injury in Malaysia. However the availability of data on the extent of alcohol abuse particularly among school children in this country is limited. Therefore, we conducted this study with the objectives of identifying the prevalence of alcohol drinking among school children in Kuala Lumpur, factors rekited to alcohol drinking among the adolescents and to assess health status of their parents through the presence of any related alcohol diseases and the habits of alcohol drinking among their parents.
In this baseline study a two stage stratified sampling design was used to recruit 8532 eligible students from the selected secondary schools in Kuala Lumpur. The prevalence of alcohol drinking was 9.0% (771 / 8532) . Significant factors identihed related to alcohol consumption were akoholic father (OR=1.29), akoholic mother (1 .55) ; elder siblings consume alcohol (2 .49) and the Chinese ethnic group (1 .55) . The study revealed that factors which signihcantly contributed to the habit of alcohol drinking were related to whether their parents consumed alcohol or not or either their eMer siblings were ako taking alcohol. Therefore, the, results from this study could be used as a baseline data to describe the level of alcohol consumption among adolescents particularly school children. Ehfective public health interventions that focus on the familial context of adolescents' drinking habits may be developed.
Family planning is a method of controlling fertility which helps to prevent unwanted pregnancies among couples. Unwanted pregnancy has negative effects for mothers and children. The aims of this study were to determine the prevalence of family planning practices among women in Serdang area and associated factors with their family planning practices. A cross sectional study was conducted with a systematic random sampling of 349 women of reproductive age, who attended Sri Kembangan Polyclinic. Descriptive analysis with chi-square and multiple regression analysis were conducted to identify factors associated with the family planning practice. The prevalence of family planning practice was 38.4%. Family planning was significantly associated with age (p=0.001), marital status (p=0.001), mode of delivery of the last pregnancy (p=0.001), number of children (p=0.001), source of information (p=0.004), level of knowledge (p=0.001), and the attitude (p=0.004). Using multiple logistic regression, four factors contributed to family planning practice, were identified as statistically significant: marital status (married OR=40, 95% CI: 9.45, 169.8), religion (Muslim OR=1.9, 95% CI: 1.14, 3.4), number of children (children>4 OR=2.98, 95% CI:1. 74, 5.09) and attitude (positive attitude OR=1.88, 95% CI:1.11, 3.18). The prevalence of family planning practice in Serdang was low even though knowledge was sufficient. The use of pamphlets and booklets are still needed to enhance efforts in health education. Currently, practice on family planning will determine the future structure of the community and the economic wellbeing of a country. Future study should focus on family planning practice among teenager and types of methods for women.
