Assessing the measurement invariance of two positive body image instruments in adults from Malaysia and the United Kingdom

Todd J, Swami V

Body Image, 2020 Sep;34:112-116.
PMID: 32505865 DOI: 10.1016/j.bodyim.2020.05.009

Despite the growth of positive body image research in recent years, our understanding of the construct across different national contexts remains limited. Here, we investigated measurement invariance of the Body Appreciation Scale-2 (BAS-2) and the Functionality Appreciation Scale (FAS) across ethnically homogenous groups of adults from Malaysia (n = 815, women n = 403) and the United Kingdom (UK; n = 596, women n = 416). Using multi-group confirmatory factor analysis, partial scalar invariance was supported for scores on both measures after fixing the intercepts for BAS-2 Items 6 and 8, and FAS Item 4. Next, we examined differences in latent scores across nationality and gender. The results of an analysis of covariance (with age and body mass index as covariates) indicated a significant nationality by gender interaction: Malaysian women had higher scores than Malaysian men on both the BAS-2 and FAS, but UK men had higher scores than UK women. There were also significant main effects of nationality (Malaysian participants had significantly higher body appreciation and functionality appreciation than UK participants) and gender (men had significantly higher body appreciation than women). These findings are discussed in terms of cross-national and gendered understandings of positive body image.

Anjum A, Usman S, Aslam A, Faiz M, Usman S, Imran MS, et al.

Trop Biomed, 2020 Jun 01;37(2):273-281.
PMID: 33612797

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides. It is characterized by anorexia, fever, dyspnea, polypnea, cough, and nasal discharges. Gross lesions in the lung such as marbling, sequestra, thickening of interlobular septa, and consolidation are evident. Serological tests including complement fixation test and competitive enzyme-linked immunosorbent assay and molecular tests such as polymerase chain reactions are used for diagnostic purposes. In this study, lung samples of suspected large ruminants (cattle n=560, buffalo n=293) were collected from abattoirs of three districts of Punjab namely Lahore, Kasur and Jhang. PCR was performed with specific primers, targeting the 16S ribosomal RNA gene to detect the positive cases. The results indicated that 49 samples (8.75%) of cattle were positive, with maximum prevalence was observed in Jhang with 16 positive samples (10.06%), but CBPP was not detected in any buffalo sample. High prevalence of disease was seen in cattle of more than seven years of age, in female cattle, and in cross-bred cattle. Age and gender were found significantly associated (P<0.05) with the prevalence of the disease. Gene sequencing of identified 5 isolates of Mycoplasma mycoides subsp. mycoides had more than 99% similarities with the strains isolated from China, Italy, Australia and Tanzania and were categorized into a monophyletic group but strain isolated from Portugal had more than 55% variable regions, hence clustered separately. This study confirms the presence of contagious bovine pleuropneumonia in the country which can be a threat to the livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

The influence of type of visual image and gender on the perception of horizontality: a subjective visual horizontal (SVH) study

Zakaria MN, Tahir A, Zainun Z, Salim R, Mohd Sakeri NS, Abdul Wahat NH

Acta Otolaryngol, 2021 Jan;141(1):62-65.
PMID: 32957810 DOI: 10.1080/00016489.2020.1817552

BACKGROUND: The graviceptive otolith function can be measured using subjective visual horizontal (SVH) testing. Nevertheless, more research efforts are required to understand the essential variables affecting SVH.
OBJECTIVE: The aim of the present study was to determine the effects of type of visual image and gender on subjective visual horizontal (SVH) perception among healthy adults.
MATERIALS AND METHODS: In this comparative study, 50 healthy young adults were enrolled. While in an upright body position, they were required to report their perception of horizontality for two types of visual images (solid line and arrow pattern) using a computerized SVH device.
RESULTS: The arrow pattern produced significantly bigger SVH angles than the solid line (p < .001). In contrast, no significant influence of gender was found on SVH results (p = .743), Based on the statistical outcomes, the preliminary normative data for SVH were established.
CONCLUSIONS AND SIGNIFICANCE: The arrow pattern (a more complex visual image) produced bigger SVH deviations than the simple solid line image. In contrast, the horizontality perception does not appear to be affected by gender. The preliminary normative SVH data gathered from the present study can be beneficial for clinical and future research applications.

Mutalip MH, Kamarudin RB, Manickam M, Abd Hamid HA, Saari RB

Alcohol Alcohol, 2014 Sep-Oct;49(5):593-9.
PMID: 25015981 DOI: 10.1093/alcalc/agu042

AIMS: To identify the characteristics of current drinker and risky alcohol-drinking pattern by profiles in Malaysia.
METHODS: We analyzed data from the National Health and Morbidity Survey 2011. It was a cross-sectional population-based with two stages stratified random sampling design. A validated Alcohol Use Disorder Identification Test Malay questionnaire was used to assess the alcohol consumption and its alcohol related harms. Analysis of complex survey data using Stata Version 12 was done for descriptive analysis on alcohol use and risky drinking by socio-demography profiles. Logistic regression analysis was used to measure the association of risky drinking status with the socio-demography characteristics.
RESULTS: The prevalence of current alcohol use was 11.6% [95% confidence interval (CI): 10.5, 12.7], among them 23.6% (95% CI: 21.0, 26.4) practiced risky drinking. The onset for alcohol drinking was 21 years old (standard deviation 7.44) and majority preferred Beer. Males significantly consumed more alcohol and practiced risky drinking. Current alcohol use was more prevalent among urbanites, Chinese, those with high household income, and high education. Conversely, risky drinking was more prevalent among rural drinkers, Bumiputera Sabah and Sarawak, low education and low household income. The estimated odds of risky drinking increased by a factor of 3.5 among Males while a factor of 2.7 among Bumiputera Sabah and Sarawak. Education status and household income was not a significant predictor to risky drinking.
CONCLUSION: There was an inverse drinking pattern between current drinker and risky drinking by the socio-demography profiles. Initiating early screening and focused intervention might avert further alcohol related harms and dependence among the risky drinkers.

Fulltext Mobile computing with special reference to readability task under the impact of vibration, colour combination and gender

Mallick Z, Siddiquee AN, Haleem A

J Hum Ergol (Tokyo), 2008 Dec;37(2):57-66.
PMID: 19227193 DOI: 10.11183/jhe1972.37.57

The last 20 years have seen a tremendous growth in the field of computing with special reference to mobile computing. Ergonomic issues pertaining to this theme remains unexplored. With special reference to readability in mobile computing, an experimental research was conducted to study the gender effect on human performance under the impact of vibration in a human computer interaction environment. Fourteen subjects (7 males and 7 females) participated in the study. Three independent variables, namely gender, level of vibration and screen text/background colour, were selected for the experimental investigation while the dependent variable was the number of characters read per minute. The data collected were analyzed statistically through an experimental design for repeated measures. Results indicated that gender as an organismic variable, the level of vibration and screen text/background colour revealed statistically significant differences. However, the second order interaction was found to be statistically non-significant. These findings are discussed in light of the previous studies undertaken on the topic.

Descriptive epidemiology of nasopharyngeal carcinoma in Peninsular Malaysia

Prasad U, Rampal L

Cancer Causes Control, 1992 Mar;3(2):179-82.
PMID: 1562708 DOI: 10.1007/BF00051659

Nasopharyngeal carcinoma (NPC) is one of the most common cancers in Malaysia, a country in Southeast Asia with a multiracial population. While hospital-based data on NPC and data from a few states have been reported, a comprehensive study involving every known NPC patient in the whole of Peninsular Malaysia in one particular year had never been done. In the present study, the computed incidence rate was not only adjusted for age, sex, ethnicity, and place of residence, but also direct standardization methods of Rothman and Dever were used to reduce any distortion. The mean age of the 365 new cases of NPC registered in 1988 was 46.8 years (SD +/- 12.2 years). The ages of patients ranged from 10 to 80 years. The incidence in both sexes rose after the age of 20-29 years and reached a plateau between 40 and 49 years. No further rise was exhibited after age 60 years. The Chinese had the highest age-adjusted incidence rates, particularly for the age group 40-49 years, where the incidence rate was 40.1 per 100,000 for males and 14.9 for females. The average age-adjusted male/female ratio was 2.8:1. Age-adjusted incidence varied by place of residence. The pattern that emerged from the data indicated the possibility of interaction between genetic susceptibility and environmental cofactors in the etiology of NPC.

Fulltext Longitudinal assessment between lifestyle-related risk factors and a composite cardiovascular disease (CVD) risk index among adolescents in Malaysia

Thangiah N, Su TT, Chinna K, Jalaludin MY, Mohamed MNA, Majid HA

Sci Rep, 2021 09 27;11(1):19135.
PMID: 34580328 DOI: 10.1038/s41598-021-98127-0

The study aims to create a composite risk index of CVD among adolescents and examine the influence of demographic, socioeconomic and lifestyle-related risk factors on the composite risk index of biological CVD risk factors among adolescents in Malaysia. A Malaysian adolescent cohort of 1320 adolescents were assessed at 13, 15 and 17 years. Seven biological CVD risk factors with moderate correlation were identified, standardized and averaged to form a composite CVD risk index. Generalised estimating equation using longitudinal linear regression was used to examine the effects of changes in adolescent lifestyle-related risk factors on the composite CVD risk index over time. From the ages 13 to 17 years, physical fitness (β = - 0.001, 90% CI = - 0.003, 0.00002) and BMI (β = 0.051, 95% CI = 0.042, 0.060) were significant predictors of attaining high scores of CVD risk. Female (β = 0.118, 95% CI = 0.040, 0.197), Chinese (β = 0.122, 95% CI = 0.006, 0.239), Indians (β = - 0.114, 95% CI = - 0.216, - 0.012) and adolescents from rural schools (β = 0.066, 95% CI = - 0.005, 0.136) were also found to be considerably significant. A more robust and gender-specific intervention programme focusing on healthy lifestyle (including achieving ideal BMI and improving physical fitness) need to be implemented among school-going adolescents.

Perceptions of plagiarisers: The influence of target physical attractiveness, transgression severity, and sex on attributions of guilt and punishment

Swami V, Arthey E, Furnham A

Body Image, 2017 Sep;22:144-147.
PMID: 28777999 DOI: 10.1016/j.bodyim.2017.06.009

The attractiveness-leniency effect (ALE) suggests that physically attractive targets are less likely to be perceived as guilty compared to less attractive targets. Here, we tested the ALE in relation to attributions of students who have committed plagiarism. British adults (N=165) were shown one of eight vignette-photograph pairings varying in target sex (female/male), physical attractiveness (high/low), and transgression severity (serious/minor), and provided attributions of guilt and severity of punishment. Analyses of variance revealed significant interactions between attractiveness and transgression severity for both dependent measures. Attractive targets were perceived as guiltier and deserving of more severe punishments in the serious transgression condition, but there was no significant difference between attractive and less attractive targets in the minor transgression condition. These results are discussed in terms of a reverse attribution bias, in which attractive individuals are judged more negatively when they fail to live up to higher standards of conduct.

Mukari SZS, Ishak WS, Maamor N, Wan Hashim WF

Ann Otol Rhinol Laryngol, 2017 Oct;126(10):697-705.
PMID: 28845678 DOI: 10.1177/0003489417727547

OBJECTIVES: Studies in cognitive aging demonstrated inconsistent association between hearing and cognition in older adults. Furthermore, it is still unclear if hearing loss at high frequencies, which is the earliest to be affected, is associated with cognitive functioning. This study aimed to determine the association between global cognitive status and pure tone average (PTA) at 0.5, 1, and 2 kHz (PTA low) and PTA at 4 and 8 kHz (PTA high).
METHODS: This study involved 307 adults aged 60 years and older. Participants had their hearing and cognition measured using pure tone audiometry and Mini Mental State Examination (MMSE), respectively.
RESULTS: Pure tone average (low) accounted for significant but minimal amount of variance in measure of MMSE. Multiple regression analyses were also performed on normal and impaired hearing cohorts and cohorts with younger (60-69 years) and older (≥70 years) groups. The results revealed a significant relationship between PTA (low) and MMSE only in the younger age group. In contrast, no significant relationship was found between PTA (high) and cognition in any of the cohorts.
CONCLUSION: Pure tone average (low) is significantly but minimally related to measure of general cognitive status. Similar relationship is not observed between high-frequency hearing and cognition. Further research using a more comprehensive cognitive test battery is needed to confirm the lack of association between high-frequency hearing and cognition.

Cochlear duct length-one size fits all?

Thong JF, Low D, Tham A, Liew C, Tan TY, Yuen HW

Am J Otolaryngol, 2017 Mar-Apr;38(2):218-221.
PMID: 28139318 DOI: 10.1016/j.amjoto.2017.01.015

OBJECTIVE: Recent studies demonstrated the utility of high-resolution computed tomography (HRCT) scans in measuring basal cochlear length and cochlear insertion depths. These studies showed significant variations in the anatomy of the cochlea amongst humans. The aim of our study was to investigate for gender and racial variations in the basal turn length of the human cochlea in an Asian population.

METHOD: HRCT temporal bone data from year 1997 till 2012 of patients with normally developed cochleae who reported with otologic disease was obtained. Reconstruction of the full basal turn was performed for both ears. The largest distance from the midpoint of the round window, through the midmodiolar axis, to the lateral wall was measured (distance A). Length of the lateral wall of the cochlea to the first turn (360°) was calculated and statistically analyzed.

RESULTS: HRCT temporal bone data from 161 patients was initially obtained. Four patients were subsequently excluded from the study as they were of various other racial groups. Study group therefore comprised of 157 patients (314 cochleae). Mean distance A was statistically different between the two sides of the ear (right 9.09mm; left 9.06mm; p=0.0069). Significant gender and racial differences were also found. Mean distance A was 9.17mm in males and 8.97mm in females (p=0.0016). The racial groups were Chinese (39%), Malay (38%) and Indian (22%). Between racial groups, mean distance A was 9.11mm (Chinese), 9.11mm (Malays) and 8.99mm (Indians). The mean basal turn lengths ranged from 19.71mm to 25.09mm. With gender factored in, significant variation in mean basal turn lengths was found across all three racial groups (p=0.04).

CONCLUSION: The view of the basal turn of the cochlea from HRCT is simple to obtain and reproducible. This study found significant differences in basal cochlear length amongst male and female Asian patients, as well as amongst various racial groups. This has implications for cochlear electrode insertion as well as electrode array design.

Regression equations to estimate the 2-min walk distance in an adult Asian population aged 40-75 years

Mirza FT, Jenkins S, Justine M, Cecins N, Hill K

Respirology, 2018 Jul;23(7):674-680.
PMID: 29446206 DOI: 10.1111/resp.13262

BACKGROUND AND OBJECTIVE: There is increased use of the 2-min walk test (2MWT) to assess functional exercise capacity. However, the distance achieved during this test may be difficult to interpret in the absence of reference values from a local population. Regression equations to estimate the 2-min walk distance (2MWD) only exist for American and Brazilian populations. The objective of this study was to develop regression equations to estimate the 2MWD in Malaysian adults who were free from major health problems.
METHODS: Eighty-seven adults (43 males; mean ± SD age: 57.1 ± 9.6 years) performed two 2MWT using a standardized protocol. Heart rate (HR) was recorded every 30 s during the test. Stepwise multiple regression analysis was performed using age, gender, height, weight and change in HR (ΔHR) as independent variables, and better of the two 2MWD as the dependent variable. A second regression equation, without ΔHR, was planned if ΔHR was retained as one of the predictors of the 2MWD in the first equation.
RESULTS: The better of the two 2MWD was 200 ± 34 m. Males walked 33 ± 6 m further than females (P < 0.001). The two regression equations were 196 - 1.1 × age, years + 1.0 × ΔHR, bpm + 31.2 × gender (R2 = 0.73) and 279 - 1.7 × age, years + 35.9 × gender (R2 = 0.47) with females = 0 and males = 1.
CONCLUSION: The equations derived in this study may facilitate the interpretation of the 2MWD in clinical populations in Malaysia, as well as in countries with similar cultural backgrounds to Malaysia.

Fulltext Normative data for hand grip strength and key pinch strength, stratified by age and gender for a multiethnic Asian population

Lam NW, Goh HT, Kamaruzzaman SB, Chin AV, Poi PJ, Tan MP

Singapore Med J, 2016 Oct;57(10):578-584.
PMID: 26768064 DOI: 10.11622/smedj.2015164

INTRODUCTION: Hand strength is a good indicator of physical fitness and frailty among the elderly. However, there are no published hand strength references for Malaysians aged > 65 years. This study aimed to establish normative data for hand grip strength (HGS) and key pinch strength (KPS) for Malaysians aged ≥ 60 years, and explore the relationship between hand strength and physical ability.
METHODS: Healthy participants aged ≥ 60 years with no neurological conditions were recruited from rural and urban locations in Malaysia. HGS and KPS were measured using hand grip and key pinch dynamometers. Basic demographic data, anthropometric measures, modified Barthel Index scores and results of the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Jebsen-Taylor Hand Function Test (JTHFT) were recorded.
RESULTS: 362 subjects aged 60-93 years were recruited. The men were significantly stronger than the women in both HGS and KPS (p < 0.001). The hand strength of the study cohort was lower than that of elderly Western populations. Significant correlations were observed between hand strength, and residential area (p < 0.001), FRT (r = 0.236, p = 0.028), TUG (r = -0.227, p = 0.009) and JTHFT (r = -0.927, p < 0.001).
CONCLUSION: This study established reference ranges for the HGS and KPS of rural and urban elderly Malaysian subpopulations. These will aid the use of hand strength as a screening tool for frailty among elderly persons in Malaysia. Future studies are required to determine the modifiable factors for poor hand strength.

Fulltext Tympanometric values in young Malay adults: preliminary data

Wahab NA, Rashid MF

Singapore Med J, 2009 Nov;50(11):1077-9.
PMID: 19960163

INTRODUCTION: The present study aimed to obtain preliminary tympanometric data of young Malay adults and to compare the results between genders.
METHODS: 96 undergraduate students (49 males and 47 females), aged 19-25 (mean and standard deviation 21.14 +/- 1.31) years, participated in this study. Otoscopic examination, pure tone audiometry, qualitative tympanogram and ipsilateral acoustic reflex were measured to ensure a clear ear canal, normal hearing and normal middle ear function, prior to tympanometric measurement. As a result, a total of 154 ears (80 ears from males and 74 ears from females) were selected for further statistical analyses. The tympanometric parameters measured were peak compensated static acoustic admittance (Peak Y(tm)), tympanometric width (TW) and equivalent ear canal volume (V(ea)).
RESULTS: The results showed that the mean Peak Y(tm), V(ea) and TW for males were 0.81 mmhos, 1.48 cubic cm and 113.67 daPa, respectively. The mean Peak Y(tm), V(ea) and TW for females were 0.63 mmhos, 1.12 cubic cm and 98.04 daPa, respectively. Males were found to have significantly higher mean V(ea) and mean Peak Y(tm) than females. However no significant gender difference was observed in the mean TW.
CONCLUSION: The current study suggests that young Malay adults may require gender-specific Peak Y(tm) and V(ea) values when implementing a quantitative approach in tympanogram interpretation.

Singapore Med J, 2010 Feb;51(2):126-32.
PMID: 20358151

INTRODUCTION: This study aimed to determine the prevalence of obesity among medical students and its relationship with their dietary intake and physical activities.
METHODS:This observational study was carried out on 240 medical students during the clinical phase of their medical course in a private medical school. Their body weight and height were measured, and a standardised questionnaire was used to collect information on their physical activities and dietary intake.
RESULTS: The median body weight of the participants was 59.0 kg (interquartile range: 51.3-66.8), the mean body height was 166.1 cm (standard deviation [SD] 8.5 cm), and the mean body mass index (BMI) was 21.8 kg/m2 (SD 3.4 kg/m2). Based on the World Health Organization BMI cut-offs for the Asian population, 30.1 percent (n is equal to 72) of the students were overweight or obese, with a BMI that was equal to or greater than 23.0 kg/m2. Logistic regression analysis showed that, after controlling for various potential confounders, the only significant risk factors associated with overweight/obesity among these students were: male gender (adjusted odds ratio [OR] 2.1; 95 percent confidence intervals [CI] of 1.1 and 4.1; p is equal to 0.03), Malay ethnic group (adjusted OR 2.4; 95 percent CI 1.0 and 5.7; p is equal to 0.04), Indian ethnic group (adjusted OR 3.6; 95 percent CI 1.5 and 8.9; p is equal to 0.005), and the number of soft drinks consumed per week (adjusted OR 1.3; 95 percent CI 1.0 and 1.5; p is equal to 0.02). Skipping breakfast, the frequency of physical exercise per week, the number of hours of sleep per day, and eating noodles or roti canai (a type of Malaysian pancake) for breakfast were not significant risk factors.
CONCLUSION: Obesity remains a common problem among medical students in their clinical years.

Fulltext Clinical applications of salivary cortisol measurements

Lo MS, Ng ML, Azmy BS, Khalid BA

Singapore Med J, 1992 Apr;33(2):170-3.
PMID: 1621122

The clinical applications of salivary cortisol measurements were evaluated by radioimmunoassay of time-matched saliva and plasma samples. Salivary cortisol levels of normal subjects exhibited a significant (p less than 0.001) diurnal variation with a mean (+/- SD) concentration of 8.7 +/- 4.8 nmol/L at 0800-1000 h and 2.4 +/- 1.1 nmol/l at 1500-1700 h. After an overnight dexamethasone suppression test, morning salivary cortisol levels decrease to 2.7 +/- 0.7 nmol/L (p less than 0.001 vs normal). An excellent correlation (r = 0.805) of cortisol measurements with time-matched saliva and plasma samples was obtained (y = 0.03x + 0.88, p less than 0.001, n = 91). Hypercortisolism was confirmed by raised salivary cortisols in only half of patients with elevated total plasma levels, thereby indicating that salivary cortisol measurements is a better index of adrenal status.

Fulltext Cigarette smoking among school children in Singapore. Part I--Smoking prevalence

Emmanuel SC, Ho CK, Chen AJ

Singapore Med J, 1990 Jun;31(3):211-6.
PMID: 2392697

A cross sectional nationally representative survey of 33,110 school-going children in Singapore aged between 9 and 20 years was carried out to obtain, for the first time, baseline information on smoking among the school-going population in Singapore. The survey was carried out among students attending vocational institutes and public sector schools in Singapore in 1987. The overall smoking prevalence was found to be 2% (3% among boys and 0.2% among girls). Ex-smokers comprised 2% of respondents whilst those who had only experimented with smoking made up 9% of the respondents. Analyses of the data showed that cigarette smoking was more prevalent among Malays, among boys, among older children, and among the less academically inclined. On average, boys smoked a median of 20 cigarettes a week and girls, 12 cigarettes a week. On an international basis, the smoking prevalence among the school-going population in Singapore is significantly lower than that of developed countries like Australia, England and Wales and neighbouring countries such as Malaysia.

Singapore Med J, 1991 Jun;32(3):166-8.
PMID: 1876890

We collected data on patients above the age of 5 years with acute bronchial asthma who presented to the emergency room of Hospital Sains Universiti Sains Malaysia during the period between 1 January to 31 March 1990. Two hundred and twelve patients (57% males and 43% females) who made a total of 271 visits were recorded. This constitutes 16.3% of all adults and paediatric medical cases seen in the emergency room during this period. The majority of patients presented between 8 pm and 6 am which contrasts with the attendance pattern due to other causes. We also recorded two peak periods of presentation (between 8 pm and 12 midnight and between 6 am and 10 am). Thirty-one (11.4%) cases resulted in admission. Of the 240 cases that were successfully treated and discharged from the emergency room, there were 59 relapses (in 45 patients). Twenty-two percent of the relapses occurred within 24 hours of the last visits. We recorded lower rates of admission as well as relapses compared to all previous studies. Our finding of bimodal pattern of presentations was also not previously reported.

Fulltext Ulcerative colitis in Malaysians: a review of 23 patients

Htut T, Kudva MV

Singapore Med J, 1989 Aug;30(4):385-7.
PMID: 2814543

Twenty-three patients with ulcerative colitis are reported from Kuala Lumpur, Malaysia. Sixteen were newly diagnosed over a six-year period between 1982 and 1987. The disease was commoner in men (16 men : 7 women). The peak age of onset was in the third decade. The ethnic distribution of the patients was 10 Malays, eight Indians and five Chinese making the disease relatively commoner amongst Indians. The extent of colonic involvement varied and six (26%) had a total colitis. Extra-intestinal manifestations were seen in seven patients. Diagnosis was delayed for over 10 years in four. Colorectal cancer was not seen. There was no mortality. Ulcerative colitis remains an uncommon disease amongst Malaysians. During the same period, only four male patients with Crohn's colitis were seen.

Orr JW, Pu TN

Singapore Med J, 1985 Apr;26(2):161-70.
PMID: 4035398

This study presents the demographical characteristics of 271 cases of parasuicide seen at the Psychiatric Clinic, General Hospital, Kuala Lumpur, during 1982. The majority of cases were women in the 20 - 30 year age group, from a lower economic class, with minimal education. About one-half were single and 61.5% were actively religious. The racial breakdown was Indians 55%, Chinese 32% and Malays 13%. Self-poisoning using easily available drugs was the most common method employed and more than one-half intended to die at the time of the suicidal act. Most attempts were impulsive, carried out while alone, inside the
house. The findings are discussed and compared with earlier studies of attempted suicides in Malaysia and Singapore.
