Fulltext The roles and challenges of the national language in uniting the various ethnic groups in Sabah

Sharifah Darmia Sharif Adam

Malaysian Journal of Social Sciences and Humanities, 2019;4(4):1-11.
MyJurnal

This paper discusses the roles and challenges of the national language, which is Malay as a language in
uniting the various ethnic groups in Sabah. On September 16, 1963, the Federation of Malaysia was
officially declared which comprised of the Malay States, Singapore, Sabah and Sarawak. In line with
that, the special provisions on the national language in Sabah are contained in Article 161 of the
national constitution. Although the provision of the constitution clarify that Sabah was given a 10-year
period to use Malay and English as the official languages but later on September 16, 1973 the Malay language was declared the sole official language for the state of Sabah. Hence, various efforts have
been made by the government to ensure the national language can play its role as a language that can
unite the various ethnic groups in Sabah. However, ethnic diversity with their own ethnic mother
tongue languages has resulted in the Malay language as a national language as well as the language of
unity to face many challenges. Therefore, the discussion in this paper is focused on policies undertaken
by the government to strengthen the national language in various fields in Sabah and the challenges
faced by the national language to foster unity among the various ethnic communities in the state. This
study was conducted using a qualitative analysis approach and used archive study methods as well as
library study to obtain research information sources. This study will produce an analysis that can be
used as a reference to improve or formulate policies particularly in matters that benefit in strengthening
the multi-ethnic communities in Sabah.

Fulltext Pre-tertiary education, ethnicity, and attitudes of Asian medical undergraduates towards communication skills

Foong AL, Sow CF, Ramasamy S, Yap PS

Int J Med Educ, 2019 Jan 25;10:1-8.
PMID: 30685752 DOI: 10.5116/ijme.5c30.988d

Objectives: This study was aimed at determining whether the pre-tertiary education system and ethnicity have any association with the attitudes of medical undergraduates towards communication skills. It also sought to determine if attitudes should have any relationship with communication skills assessment outcomes.
Methods: A cross-section survey design was performed with 323 participants from two cohorts of medical undergraduates, i.e., first-year (n = 153) and second-year students (n = 170) who completed the Communication Skills Attitude Scale. Participants comprised of the main ethnic groups in Malaysia, i.e., Malays, Chinese and Indians, from different language medium pre-tertiary education backgrounds. Attitude measurements were compared with OSCE outcomes.
Results: There was a significant difference in Negative Attitude Scale between pre-tertiary education system with attitudes towards communication skills (F (3, 319) = 7.79, p = .001), but no significant difference with Positive Attitude Scale (F (3, 319) = 0.43, p = .649). There was no significant difference between ethnicity and attitudes towards communication skills with PAS (F (2, 320) = 0.66, p = .519) and NAS (F (2, 320) = 1.24, p = .291). Students from Chinese medium education system had stronger negative attitudes with a mean score of 14.7 (n = 56, SD = 3.6) for primary school levels and 15.9 (n = 17, SD = 3.0) for secondary school levels, compared with others. There was no significant prediction of student's attitudes towards assessments outcomes.
Conclusions: Preliminary findings from the small data pool suggest indicative relationships requiring further studies with more participants and proportionate pre-tertiary education system backgrounds.

Fulltext Radiographic appearance of susuk in the facial region: a systematic review

Ahmad Badruddin Ghazali, Nur Imanina Abdullah Thaidi

Malaysian Journal of Medicine and Health Sciences, 2020;16(3):295-299.
MyJurnal

The purpose of this study was to integrate the available data published to date on susuk or charm needles into a com- prehensive analysis of their clinical/radiological features. An electronic search was undertaken in September 2019. Eligibility criteria included publications having enough clinical and radiological to confirm a definite diagnosis. The initial literature search resulted in 48 publications. Ten publications were excluded for duplicates, and another 17 excluded after a screening of the abstract. Besides, the screening of the abstract shows that five publications were not meeting the inclusion criteria, resulting in a total of 14 publications of susuk that were included in the systematic review. Bias analysis was conducted according to Oxford Center for Evidence-Based Medicine. The resulting total of 78 cases from the selected publications were analysed, showing a wide age range with different distribution among gender and ethnicity. Three cases reported in the literature having symptoms related to susuk. Susuk can be seen as an incidental finding during a routine radiographic assessment, and clinicians should be able to differentiate it from other radiopaque foreign bodies. The practice is not limited to South East Asian population and can be seen in wide racial profiles.

MyJurnal

Introduction: A parallel design randomized clinical trial was conducted to compare dentoalveolar and skeletal changes in two groups of patients who had completed twin block therapy; one group had a three-month night-time retention period whereas the other group had no retention period, after twin block therapy but before fixed applianc- es. Methods: 26 participants of Malay ethnicity aged 10 to 15 years were included in the trial and had an overjet of 5mm or greater, molar relationship greater than half cusp Class II on a skeletal Class II base which had been corrected to a Class I molar relationship following twin block therapy. Following randomization, the 26 were divided into two groups of 13. Group A had fixed appliances bonded immediately whereas group B continued wearing twin block at night for three months, after which fixed appliances were bonded. Lateral cephalograms assessed were those taken before randomization, upon twin block therapy completion (T1) and six months after bond-up of fixed appliances (T2). Results: Paired t-test showed several statistically significant dentoalveolar and skeletal changes in group A. In contrast, only condylar head position exhibited a statistically significant change in group B. Despite a statistical sig- nificance, changes measured in both groups were minimal at less than 2mm and therefore clinically insignificant. Independent t-test showed no statistically significant difference between the changes recorded in both groups. Con- clusion: The results suggest that a three-month night-time retention period after twin block therapy does not lead to any changes that may be considered clinically beneficial.

Selvaraj S, Naing NN, Wan-Arfah N, de Abreu MHNG

Int J Environ Res Public Health, 2021 07 26;18(15).
PMID: 34360201 DOI: 10.3390/ijerph18157910

The aim of this study was to evaluate the performance of a set of sociodemographic and habits measures on estimating periodontal disease among south Indian adults. This cross-sectional study was carried out among 288 individuals above 18 years old in Tamil Nadu, India. The outcome of the study was periodontal disease, measured by WHO criteria. The covariates were age, ethnicity, smoking and alcohol habit. The assessment of factors predicting periodontal disease was carried out by multiple logistic regression analysis using R version 3.6.1. The demographic factors like age group (AOR = 3.56; 95% CI 1.69-7.85), ethnicity (AOR = 6.07; 95% CI 2.27-18.37), non-alcoholic (AOR = 0.31; 95% CI 0.13-0.64) and non-smoking (AOR = 0.33; 95% CI 0.15-0.67) were found to be associated with the outcome. The maximum log likelihood estimate value was -30.5 and AIC was 385 for the final model, respectively. Receiver operating characteristic (ROC) curve for the periodontal disease was 0.737. We can conclude that sociodemographic factors and habits were useful for predicting periodontal diseases.

Fulltext Comparing and determining factors associated with hypertension self-care profiles of patients in two multi-ethnic Asian countries: cross-sectional studies between two study populations

Wee SY, Salim H, Mawardi M, Koh YLE, Ali H, Shariff Ghazali S, et al.

BMJ Open, 2021 06 14;11(6):e044192.
PMID: 34127489 DOI: 10.1136/bmjopen-2020-044192

OBJECTIVES: To compare the sociodemography, disease characteristics and hypertension self-care profiles and to determine the factors influencing Hypertension Self-Care Profiles (HTN-SCP) in two populations in primary care settings from Singapore and Malaysia.
DESIGN: Cross-sectional, cross national.
SETTING: Multi-centre, primary care clinics Malaysia and Singapore.
PARTICIPANTS: 1123 adults with hypertension enrolled and analysed.
PRIMARY AND SECONDARY OUTCOME MEASURES: Comparison between sociodemography, disease characteristics and the mean scores of HTN-SCP domains (behaviour, motivation and self-efficacy) and the factors influencing hypertension self-care.
RESULTS: 1123 adults with hypertension attending primary care clinics in Malaysia and Singapore were involved. The participants' mean age was 63.6 years (SD 9.7) in Singapore and 60.4 (SD 9.1) in Malaysia. Most of the participants in Singapore had tertiary education (22.3%) compared with Malaysia (13.0%), p<0.001. A higher proportion of participants from Singapore had controlled blood pressure (74.6%) compared with Malaysia (33.8%), p<0.001. The mean total score of HTN-SCP was significantly higher among Singapore participants compared with Malaysia participants 190 (SD 28) versus 184 (SD 23) (p<0.001). Similarly, the mean score for motivation domain 67 (SD 10) versus 65 (SD 9), followed by self-efficacy score 65 (SD 11) versus 62 (SD 9) and behaviour score (58 SD 9 vs 56 SD 9) were higher among Singapore participants. In both countries, the factors which influenced higher HTN-SCP mean scores across all domains were being Indian and had tertiary education.
CONCLUSIONS: The study population in Singapore had a higher HTN-SCP mean score compared with Malaysia. The common factors influencing higher HTN-SCP mean scores at both study sites were ethnicity and level of education. Future intervention to improve self-care among people with hypertension may need to be tailored to their behaviour, motivation and self-efficacy levels.

Fulltext Asthma symptoms and respiratory infections in Malaysian students-associations with ethnicity and chemical exposure at home and school

Norbäck D, Hashim Z, Ali F, Hashim JH

Environ Res, 2021 06;197:111061.
PMID: 33785322 DOI: 10.1016/j.envres.2021.111061

Little is known on respiratory effects of indoor chemicals in the tropics. We investigated associations between asthma and respiratory infections in Malaysian students and chemical exposure at home and at school. Moreover, we investigated differences in home environment between the three main ethnic groups in Malaysia (Malay, Chinese, Indian). Totally, 462 students from 8 junior high schools in Johor Bahru participated (96% participation rate). The students answered a questionnaire on health and home environment. Climate, carbon dioxide (CO2), volatile organic compounds (VOC), formaldehyde and nitrogen dioxide (NO2) were measured inside and outside the schools. Multilevel logistic regression was applied to study associations between exposure and health. Totally 4.8% were smokers, 10.3% had wheeze, 9.3% current asthma, and had 18.8% any respiratory infection in the past 3 months. Malay students had more dampness or mould (p ethnicity (p = 0.02; lower in Indian), atopy (p = 0.002), current smoking (p = 0.02) and recent indoor painting at home (p = 0.03). Current asthma was associated with ethnicity (p = 0.001; lower in Chinese) and para-dichlorobenzene in classroom air (p = 0.008). Respiratory infections were related to atopy (p = 0.002), ethylbenzene (p = 0.02) and para-dichlorobenzene (p = 0.01) in classroom air. Para-dichlorobenzene is used in Asia against insects. In conclusion, chemical emissions from recent indoor painting at home can increase the risk of wheeze. In schools, para-dichlorobenzene can increase the risk of current asthma and respiratory infections while ethylbenzene can increase the risk of respiratory infections.

Jurnal Sains Nuklear Malaysia, 2013;25(1):29-34.
MyJurnal

This paper aims at presenting preliminary results of a survey on physical factors, namely tube
potential (kV), tube current exposure time product (mAs) and compressed breast thickness (CBT)
during voluntary mammography screening using Full-Field Digital Mammography (FFDM) System
in Malaysia. Retrospective data were collected from 1128 FFDM images of 282 women from three
major ethnic groups (Malay, Chinese and Indian) who underwent voluntary screening
mammography at Breast Centre, International Islamic University Malaysia from January to March
2008. Results from the present study were then compared with results from the previous study on
Screen-Film Mammography System (SFM) according to the ethnic group for both Cranio-caudal
(CC) and Mediol-Lateral (MLO) views. We found that the mean kV for CC view for the three ethnic
groups are Malay (28), Chinese (28) and Indian (28), and for MLO view are Malay (29), Chinese
(28) and Indian (29). These values are higher than the kV for SFM which were Malay (26), Chinese
(27) and Indian (26) for CC and Malay (26), Chinese (27) and Indian (26) for CC and MLO views
respectively. The mean mAs for CC and MLO views for FFDM were lower compared to SFM
systems. These values were Malay (104), Chinese (108) and Indian (91) for CC views and Malay
(106), Chinese (105), and Indian (94) for MLO views for the FFDM system. The values for SFM
system are for CC and MLO views were Malay (120), Chinese (106) and Indian (126), and Malay
(166), Chinese (132), Indian (183) respectively. The median CBT for CC and MLO views increased
by 27% and 7% respectively on the FFDM compared to the SFM system. In conclusion, the FFDM
operates with higher kV, lower mAs, and higher CBT when compared with SFM system. Median
CBT on CC and MLO view with FFDM system are 27% and 7% higher respectively compared to
the SFM. We are currently collecting data on mean glandular dose with FFDM systems to assess
how the change in local mammography practice influences this value. This will allow comparison
with related data from other parts of the world.

International Food Research Journal, 2015;22(2):731-738.
MyJurnal

This study was carried out to determine recognition threshold and taste preference for three basic tastes (sweetness, saltiness and sourness) based on location (interior and coastal) among the Kadazandusun ethnic in Sabah, Malaysia. One hundred and ninety four (194) volunteers aged 20 to 55 years were selected randomly (stratified) as subject. Three Alternative Forced- Choice (3AFC) and hedonic test were used to determine the taste threshold and preference. The interior group had lower taste threshold for all tastes; sweet (10.97 g/L ± 3.69), salty (1.14 g/L ± 0.38), sour (0.0095 g/L ± 0.011) compared to the coastal group; sweet (11.56 g/L ± 3.71), salty (1.23 g/L ± 0.39), sour (0.0012 g/L ± 0.0034). For intensity and hedonic rating, the patterns of response varied based on location for sweet and sour taste. No significant different (p>0.05) was observed for salty taste. However, both groups preferred the base stimulus which concentration similar to the commercially available products tested. There is a correlation between taste threshold and optimum concentration. Individuals with preferred high taste intensity tend to have higher taste threshold. Location and culture can influenced individual taste preference. However, exposure and experience to taste sensation was the major factor on individual’s taste preference.

Ergonomics is generally to design for human use and optimizing the working and living conditions. The comfort, safety and ease of use of systems, products and machines require the principles of ergonomics to be incorporated into the design. Anthropometry is a part of ergonomics which deals with the measurement of body dimensions, its capability and limitations of the human ability. Studies have indicated that body dimensions differ for various populations, depending on ethnic group, sex and age. The measurement of physical characteristics and abilities of people provides information that is essential for the appropriate design of occupational and non- occupational environments, as well as for the design of consumer products, clothing, tools and equipment. It has been considered as the very basic core of ergonomics in an attempt to resolve the dilemma of 'fitting people to machines'. It has also been regarded as a branch of anthropology which deals with physical characteristics of the man in time and space, particularly with individual variation, ontogenesis and generic development. Knowledge about man from the point of view of physical anthropometry is very useful for the purpose of ergonomics and design. Thus it is important that an anthropometric database for each nation is developed to ensure design of products and systems are compatible with the user population. In Malaysia, many researchers have conducted anthropometric studies on various groups of people, focused on a small sample size and used for specific designs. Unfortunately, the measurements are not representatives of the population. The work has been individually based, confined to certain group of researchers in various universities and there is no concerted effort towards developing a national anthropometric database.This paper discusses some of the anthropometry work conducted in Malaysia, the problems and challenges in developing the national database, the importance of anthropometry and the roles that the government has to play in developing the database.

Fulltext A review of metabolic syndrome research in Malaysia

Lim KG, Cheah WK

Med J Malaysia, 2016 06;71(Suppl 1):20-28.
PMID: 27801385 MyJurnal

Seventy-three articles related to metabolic syndrome were found in a search through databases dedicated to indexing all literature with original data involving the Malaysian population between years 2000 and 2015. Metabolic syndrome affects 25 to 40% of adult population of Malaysia with the risk increasing with age. Obese children are also at risk. Indian ethnicity has the highest rates, followed by Malay and chinese. It was found that socioeconomics determinants such as living in urban areas, unemployment, lower income, lower education level and shift workers had higher prevalence of metabolic syndrome. Metabolic syndrome is associated with other medical conditions like cardiovascular diseases, psychiatric disorders, erectile dysfunction, polycystic ovarian syndrome and colorectal cancer. Several biomarkers have been determined to be relevant to our local population but their usage in clinical setting needs further research. Literature into effectiveness of management of metabolic syndrome in Malaysia is lacking and the results were only modest. there are several diagnostic criteria available for metabolic syndrome internationally and their individual significant to our local population is not clear. It also makes it difficult to compare results between studies using different criteria. Finally, we could not identify any local study to look at the health economic burden of metabolic syndrome locally.

Archives of Orofacial Sciences, 2007;2(1):36-40.
MyJurnal

The purpose of this study was to determine the timing and sequence of emergence of the first 28 permanent teeth in a cross-section of Malay children in the district of Kota Bharu, in northeastern Peninsula Malaysia. The sample consists of 478 boys and 908 girls of Malay descent aged between 5-19 years. The criterion for tooth emergence was the appearance of the tooth through the gingivae. Descriptive statistics were calculated and probit regression analysis performed to determine the mean age of emergence of the permanent dentition. The mean age at emergence was found to conform to general trends, with emergence seen earlier in girls than in boys. Comparisons were made with the Chinese (Hong Kong) and the Punjabi (Chandigarh) profiles, which showed earlier emergence timings in those ethnic groups. The emergence timing in Malays, however, was earlier than in Thais (Central Thailand). The sequence of emergence was determined by referring to the mean age of tooth emergence of individual teeth and conforms to the general trend seen in other studies.

Injury Hncluding home injury} is an important contributor to the nations’ statistics on mortality and morbidity. However, statistics on injury is still lacking in Malaysia. In 1996, the National Health and Morbidity Survey was conducted nationwide that includes injury as one ofthe scope studied at the community level. It was found that the prevalence of sefreported home injury in Malaysia was 2.5%. The prevalence was higher among the 0-4 years and more than 80 years groups. There was no dwzrence in the prevalence of injury by urban/rural location, ethnicity, citizenship, religion, marital status, level of education, income group or type of occupation. Females however reported a slightht higher figure than males (2. 7% i· 95% CI and 2.3% i 95% CD. Recommendations made include planning and designing of preventive intervention strategies and sreas for future studies.

This cross-sectional study was carried out to identify A. actinomycetemcomitans and P. intermedia in the subgingival plaque of three ethnic groups (Malays, Chinese and Indians) in a selected group of adult Malaysians with advanced Chronic Periodontitis and to correlate these findings with their periodontal status. Thirty periodontally diseased adults were age, gender and ethnically matched with 30 healthy individuals. Clinical parameters were assessed for all. Subgingival plaque samples were collected for identification of A. actinomycetemcomitans and P. intermedia using polymerase chain reaction. Prevalence for P. intermedia (83.3%) was high and A. actinomycetemcomitans
(6.7%) low in the total subject population. P. intermedia and A. actinomycetemcomitans were more
prevalent in diseased (86.7%, 10% respectively) than in healthy (80%, 3.33% respectively) subjects. A. actinomycetemcomitans was detected in 15% Indians, 5% Malays but none of the Chinese subjects whereas P. intermedia was detected in 90% Malays, 85% Indians and 75% Chinese subjects. No significant association between presence of A. actinomycetemcomitans
and P. intermedia with race and periodontal disease status was found. Only A. actinomycetemcomitans had a significant association with clinical attachment level (CAL) (p < 0.05). In conclusion, in this small subject group, none of the pathogens were associated with race and periodontal disease status and only A. actinomycetemcomitans had a significant association with CAL.

MyJurnal

Chronic periodontitis (CP) is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganism. Hypertension is one of the major causes of cardiovascular disease whereas periodontitis has recently drawn increasing attention because of its potential relationship with cardiovascular disease. The objectives of this study were to determine the prevalence of the hypertension in CP patients as well as to evaluate the association between hypertension and severity of CP. One hundred and eighty five records of CP patients treated in Dental Clinic, Universiti Sains Malaysia Hospital (USM Hospital), Kelantan from 2010 until 2013 were retrieved and reviewed. The diagnosis of periodontal disease and the presence of hypertension were recorded. The severity of chronic periodontitis was classified into mild, moderate and severe according to the clinical attachment loss. The data was obtained and analyzed using SPSS version 20.0. Majority of the subjects were from Malay ethnic group (94.4%) at the age range between 41 and 61 years (67.8%). In conclusion, the prevalence of hypertension in chronic periodontitis patients was 12.2%. There was no significant association between hypertension and severity of CP (p=0.229).

Psychological stress among undergraduate students is associated with poor academic results, physical ill-health and psychiatric disorders. The objectives of the study were to determine the prevalence of psychological stress and its associated factors among undergraduate students attending a health programme in a local university. This is a cross-sectional study among undergraduate students attending a health programme in a local university. The 12-item General Health Questionnaire (GHQ-12) was used to determine the presence of psychological stress at a cut-off point of 4 and above. Analysis was conducted to determine any association between gender, ethnicity, year of study in the university, recent health-seeking contact with a doctor, and psychological stress among the participants. The prevalence of psychological stress among undergraduate students attending a health program in a Malaysian University was 49.3%. There was no significant association with any of the socio-demographic factors studied (p>0.05). The prevalence of psychological stress in this study was significantly high, and irrespective of gender, ethnicity, year of study in the university, and recent health-seeking contact with a doctor. Hence, the findings of this study show that it may be a useful strategy to integrate such health programs regularly in activities of colleges and universities, with the aim of promoting mental health and wellness among the students.

The role of kin-structured migration in genetic microdifferentiation

Fix AG

Ann. Hum. Genet., 1978 Jan;41(3):329-39.
PMID: 626477

Most current models of human population structure view migration solely as a deterministic force reducing the variance in gene frequencies among the local colonies of a subdivided population. By an empirical example and through simulation experiments, it is shown that migration structured along kinship lines (by analogy to the lineal or 'kinship' effect) does not always reduce the variances of gene frequencies arising through intergenerational random genetic drift. Thus populations experiencing high rates of migration may not be genetically homogenous.
