    AIM: Elder abuse is a significant public health problem. This study aims to estimate its prevalence and associated factors, using representative national Malaysian data.

    METHODS: A nationwide population-based survey involving 3977 community-dwelling older persons aged ≥60 years was conducted via face-to-face interview, of whom 3466 older persons were eligible for screening using a locally validated tool. Elder abuse was defined as any one occurrence of neglect, financial, psychological, physical or sexual abuse perpetrated by someone in a position of trust that was experienced in the past 12 months.

    RESULTS: About 9.0% of older persons in Malaysia have experienced elder abuse in the past 12 months, with neglect being the commonest type experienced (7.5%; 95% confidence interval [CI]: 5.54, 10.07). There is no significant difference by age group and geographical location. Males (adjusted odds ratio [aOR] 1.7; 95% CI: 1.06, 2.60), poorer social support (aOR 5.0; 95% CI: 2.25, 11.22), dependency in activities of daily living (aOR 2.1; 95% CI: 1.23, 3.44) and a previous history of abuse (aOR 10.1; 95% CI: 4.50, 22.86) show higher odds of experiencing elder abuse. Almost 5% of abused older persons reported experiencing multiple types of abuse. Reporting is low at 19.3% with none reporting to healthcare personnel.

    CONCLUSIONS: The prevalence of elder abuse in this study is lower than global estimates, but similar to local studies. Preventive measures and programs are crucial to overcoming elder abuse and need to be carried out at multiple levels - the individual, community, healthcare and other stakeholders.

  2. Fulltext Clinical features of malaria in Orang Asli population in Pos Piah, Malaysia
    Norhayati M, Rohani AK, Hayati MIN, Halimah AS, Sharom MY, Zainah Abidin AH, et al.
    Med J Malaysia, 2001 Sep;56(3):271-4.
    PMID: 11732070
    A malaria survey was conducted to examine the presence of common clinical features of malaria in individuals living in an endemic area of malaria. The overall infection rate was 11.0% with 7.5% and 3.5% infected with Plasmodium vivax and Plasmodium falciparum respectively. The mean parasitaemia level of both species was 2905.9 parasites/microliter blood, with the mean parasitaemia level of P. vivax and P. falciparum at 682.7 parasites/microliter blood and 6981.7 parasites/microliter blood respectively. The infection rates were higher in the younger age group. Hepatomegaly, hepatosplenomegaly and clinical anaemia were significantly associated with malaria. None of the patients were febrile. In conclusion, in low endemic areas, the presence of clinical anaemia, hepatomegaly and hepatosplenomegaly in afebrile individuals could be considered as useful criteria for the presence of asymptomatic parasitaemia. It is important to carry out laboratory diagnostic investigations, to ensure all the asymptomatic parasitaemia which act as reservoirs are detected and treated.

    Teh GC, Sahabudin RM, Lim TC, Chong WL, Woo S, Mohan M, et al.
    Med J Malaysia, 2001 Jun;56(2):186-95.
    PMID: 11771079
    Objective: To study the prevalence of symptomatic BPE among Malaysian men age 50 and above attending prostate health awareness campaign and to identify differences in prevalence between different ethnic groups residing within metropolitan Kuala Lumpur.
    Materials and Methods: Demographic data and the completed International Prostate Symptom Score (IPSS), maximal uroflow rate (Qmax) and prostate size of volunteers, aged 50 and above, who attended the prostate health awareness campaign were analyzed. Subjects with known prostate diseases or prostate surgery, bladder disorders and neurological disorders were excluded.
    Results: 2086 volunteers attended the campaign. 575 men fulfilled the inclusion criteria and their demographic data, IPSS; peak flow rate and prostate volume were analysed. Overall, 18.9% and 39.6% of the men were severely and moderately symptomatic, respectively. The prevalence of moderate to severe lower urinary tract symptoms (LUTS) in Malays, Chinese and Indians were 70%, 59% and 50% respectively (p=0.004). The commonest bothersome symptoms were nocturia (56%), frequency (50.4%) and sense of incomplete voiding (43.5%). The mean peak flow rate of the subjects was 15.4ml/s. 20.9% and 55.2% of the subjects had peak flow less than 10ml/sec and 15ml/sec respectively. The mean prostate size was 25.1cc. There is no significant difference in term of maximal flow rate and prostate size among Malays, Chinese and Indians in Malaysia. A good correlation was found between the total symptom score and the single disease-specific quality of life question (r=0.69, p<0.001). The correlation between IPSS and peak flow rate (r=-0.22, p<0.001) and prostate volume (r=0.11, p=0.009) was weak. There was no correlation between IPSS and age (r=0.06, p=0.17). The prevalence of symptomatic benign prostate enlargement (BPE) was 39.3%. The prevalence increased 8% per decade from 41.7% for men aged 50 to 59 to 65.4% for men aged 70 or more. There is no significant difference in prevalence of symptomatic BPE among the three ethnic groups. The prevalence of BPO was 15.8%.
    Conclusion: The correlation between symptom score, maximal flow rate and prostate size was poor and one cannot predict the value of one parameter by knowing one or more of the other parameters. There is a high prevalence of LUTS suggestive of benign prostatic obstruction in the apparently healthy Malaysian aged 50 and above attending the prostate health awareness campaign.

    Norhayati M, Penggabean M, Oothuman P, Fatmah MS
    Southeast Asian J Trop Med Public Health, 1998 Dec;29(4):735-8.
    PMID: 10772555
    A study on prevalence and risk factors of Giardia duodenalis infection was conducted in rural communities of Malaysia. A total of 917 individuals between 2-70 years old (431 males and 486 females), participated in this study. The overall prevalence of G. duodenalis infection was 19.2%. The prevalence was significantly different between different age groups, but not genders. Our study indicated that age < or = 12 years old and the presence of family members infected with G. duodenalis were the risk factors of infection. Person-to-person contact within the family members was the possible mode of transmission. Health education on personal hygiene, together with the treatment of the infected people, may help in reducing and controlling this infection in these communities.

    PMID: 10783442
    Analysis of case records of 46 patients with peripheral odontogenic fibroma (1967-95) diagnosed in the Division of Stomatology, Institute for Medical Research, Kuala Lumpur, disclosed a relatively young age of onset (mean, 32.2 years; range 5 months-64 years; peak incidence second decade of life), a slight female preponderance (M:F ratio 1:1.3), no racial predilection, a slight bias towards location in the mandible (52%) and a wide histomorphological range. All cases were treated by simple excision. Follow-up records were generally not available, so we do not know what the recurrence rate is.

  7. Oral recurrent aphthous ulcers/stomatitis: prevalence in Malaysia and an epidemiological update
    Zain RB
    J Oral Sci, 2000 Mar;42(1):15-9.
    PMID: 10808270
    One of the objectives of this short communication was to add to the literature on the prevalence of oral recurrent aphthous stomatitis (ORAS). This research is based on a total of 11,697 randomly selected Malaysian subjects with an age range of 25-115 years and a mean age of 44.5 +/- 13.9 years who were examined for oral mucosal lesions (ORAS). The prevalence of ORAS detected during the oral examination (average point prevalence) was found to be 0.5% (64 subjects). ORAS formed 5.7% of all lesions detected during the survey. The average point prevalence of ORAS was highest in the indigenous people of Sabah and Sarawak (1.2%), followed by the Chinese (0.7%), the Malays (0.5%) and the Indians (0.1%). This difference was statistically significant (p < 0.001). A review of the English literature on the prevalence of ORAS revealed different prevalence types used by different researchers, namely average point prevalence (APP), self reported life-time prevalence (SLP) and self reported two-year prevalence (STP). The other objective of this paper was to present the different types of prevalence that have been reported in the literature and to discuss the usefulness of such prevalence types in relation to using epidemiology in deriving certain possible etiological associations.

  8. Thyroid volumes in a national sample of iodine-sufficient swiss school children: comparison with the World Health Organization/International Council for the control of iodine deficiency disorders normative thyroid volume criteria
    Hess SY, Zimmermann MB
    Eur. J. Endocrinol., 2000 Jun;142(6):599-603.
    PMID: 10822222
    The determination of goiter prevalence in children by thyroid ultrasound is an important tool for assessing iodine deficiency disorders. The current World Health Organization/International Council for the Control of Iodine Deficiency Disorders (WHO/ICCIDD) normative values, based on thyroid volume in iodine-sufficient European children, have recently been questioned, as thyroid volumes in iodine-sufficient children from the USA and Malaysia are smaller than the WHO/ICCIDD reference data. Our objective was to describe ultrasonographic thyroid volumes in a representative national sample of iodine-sufficient Swiss school children, and to compare these with the current reference data for thyroid volume.

    Med J Malaysia, 1997 Jun;52(2):139-45.
    PMID: 10968071
    We report a cross-sectional descriptive study of 90 new long-stay patients (NLS) (i.e. those who had been resident for six months to three years in Permai Mental Hospital, Johor) and studied from April to June, 1995. The age of this sample ranged from 18 to 85 years. Two subgroups were observed (i.e. younger NLS patients aged 18 to 34 years and older NLS patients aged 35 to 85 years). Among the younger NLS patients, the commonest diagnosis was schizophrenia (51.2%), followed by mental retardation with related problems (24.4%). Sixty-one percent of these younger patients had a history of serious violence or dangerous behaviour. Older NLS patients were likely to have a diagnosis of schizophrenia (79.6%), followed by mood disorder (6.1%) and dementia (4.1%). Forty seven percent of these older group had history of danger to others and 57.1% were at moderate or severe risk of non-deliberate self-harm. Focusing on the schizophrenic patients, all of them had some form of psychopathology, either positive, negative or general symptoms and about one-fourth were assessed to pose a risk for aggression.

    PMID: 9395810
    The incidence of congenital dislocation of the hip (CDH) in Singapore and Malaysia has been reported as being lower than in the West. In our hospital, we have seen an increasing number of congenital hip dislocation as well as dysplastic hips. We undertook a prospective study from December 1989 to December 1994 of 20,000 live births. The neonates were all screened by a consultant neonatologist and the findings were confirmed by a consultant paediatric orthopaedic surgeon. All babies had plain X-rays at 3 months and an acetabular index (AI) of 30 degrees or more was considered dysplastic. All babies with positive signs were followed up for 1 year and again had radiographs taken at 1 year. Comparison of plain X-rays and ultrasound assessment in a subgroup of 130 neonates showed that 64% of patients with AI > 20 degrees had hip dysplasia by ultrasonographic (alpha angle < 60 degrees) The incidence of dysplastic hips was 16.8 per 1000 live births. The overall incidence of neonates with dislocated hips was 4.7 per 1000 live births. The Malays were most affected with an incidence of 5.4 per 1000 live births. The incidence of developmental dysplasia of the hip in Singapore is higher than previously reported, with the Malays having the highest incidence. A significant number of babies with clicking hips have radiological evidence of acetabular dysplasia (AI > 30 degrees). One-third of the babies' hips were still dysplastic at 1 year of age. A well-organised screening programme with experienced examiners has proved to be useful in making early and accurate clinical diagnosis.

    Sivarao S, Vidyadaran MK, Jammal AB, Zainab S, Goh YM, Ramesh KN
    Placenta, 2002 10 4;23(8-9):691-6.
    PMID: 12361688
    This study was conducted to determine the effect of ethnicity on maternal, placental and neonatal parameters. Maternal, placental, and the newborn parameters were corrected for gestational age. The male:female sex ratio was 1:1.03. One hundred and forty-four freshly delivered placentae from 55 Malaysian, 51 Chinese, and 38 Indian normal healthy patients were collected and standard stereological methods used to estimate the placental parameters. Pearson's correlation, Spearman's correlation and 1-way ANOVA were used to test significance of differences. Placental surface area, placental weight and placental volume of Indians were lower than Malays (P< 0.05). Placental weight correlated significantly with neonatal length (r=0.527), birthweight (r=0.665), head circumference (r=0.371) and booking weight (r=0.193) while placental volume correlated with neonatal length (r=0.588), birthweight (r=0.688), head circumference (r=0.384), parity (r=0.202) and booking weight (r=0.219) at P< 0.05. Indian babies weight and length were less than Chinese and Malay babies (P< 0.05) while booking weight of Indian mothers was less than those of Chinese mothers (P< 0.05). Even after being corrected for booking weight, placental parameters of Indian patients were still significantly less than Malays and Chinese (P< 0.05).

    PMID: 11072489 MyJurnal
    Motorcyclists make up the largest group of fatalities on Malaysian roads, majority succumbing to head injuries despite the compulsory safety helmet laws in the country. One possible reason for this high fatality is improper usage of safety helmets. This study examines the compliance of proper safety helmet use in motorcyclists in a typical Malaysian town. Five hundred motorcyclists were studied. Only 54.4% of motorcyclists used helmets properly, 21.4% used them improperly; and 24.2% did not wear helmets. Six variables were found to be significant in improper safety helmet use. They were age, gender, race, formal education level, prior accident experience and type of license held. Marital status and riding experience were not significant. Efforts promoting proper use of safety helmets should focus on the young, male, less formally educated, unlicensed rider, who has had a prior accident.

  17. Interindividual variation in circulating zinc concentrations among healthy adult men and women
    Hashim Z, Woodhouse L, King JC
    Int J Food Sci Nutr, 1996 Sep;47(5):383-90.
    PMID: 8889623
    Circulating zinc concentrations were measured in 73 healthy adult males and females 19-52 years of age who were volunteers for eight different metabolic studies at the University of California, Berkeley. The interindividual variation in the eight studies varied from 5 to 20%; the global coefficient of variation for all studies was 12 +/- 7% (mean +/- SD). The analysis of a reference plasma sample on six different days showed a mean coefficient of variation of 3.8%. Thus, only a small portion of the intraindividual variation is due to day-to-day analytical differences. There was no relationship between circulating zinc concentrations and age, height, or body mass index. Nor were there any significant differences due to gender. Information regarding dietary zinc and protein intakes was available from three-day weighed food intake records from 44 of the subjects. Plasma zinc concentrations were unrelated to the intake of either zinc or protein in those subjects. The results of this study show that the impact of age, gender, body size and dietary zinc or protein on circulating zinc concentrations are too small to be detected in the presence of the analytical and endogenous factors that influence plasma/serum zinc concentrations. Also, within a population of healthy adults, circulating zinc concentrations may vary by as much as 15%.

  18. Distribution of hair on the dorsum of the phalanges of the hand in a Chinese population from Malaysia
    Dharap AS, Lim BC, Ong LB
    Anthropol Anz, 1996 Dec;54(4):311-6.
    PMID: 9008788
    Hair distribution on the dorsum of phalanges of the hand was studied on 302 Chinese subjects (134 males and 168 females) randomly selected from the residents of Kota Bharu, Malaysia. Proximal phalangeal hair was seen on the dorsum of both hands in 99.3% of male subjects but in only 85.1% of female subjects. Chinese females showed a significantly lower (p < 0.05) incidence of proximal phalangeal hair on the hands than Chinese males. Comparison with other racial groups showed that Chinese females had significantly less (p < 0.05) hair on the proximal phalanges of the hands than Malay and African (Nigerian) females. The least common digital combination of proximal phalangeal hair in female subjects was the presence of proximal phalangeal hair only on the fourth digit (ring finger) and was noted in 0.6% of subjects. This has not been reported before. The frequency of middle phalangeal hair (MPH) distribution in Chinese falls between that in Malays and in Japanese which is probably explained by the fact that all these three racial groups originate from Asia. A study of digital combination of MPH in Chinese showed that the most common and the least common combinations in the Chinese differ considerably from those in other races. A total of 16 patterns of hair distribution was noted on the dorsum of the phalanges of the hands in Chinese subjects. Our study showed that though Chinese females had less digital hair on the hands than Chinese males, they showed a much larger variety of patterns of digital hair distribution than males.

    We performed a vision screening of 1883 Chinese schoolchildren from 4 schools around Kuala Lumpur in June 1990. The group contained 1083-males and 800 females. Visual acuity, refractive error, oculomotor balance, and axial length were measured. The prevalence of myopia in Chinese schoolchildren was found to be 37% in the 6- to 12-year age group and 50% in the 13- to 18-year age group. Approximately 63% of the sample had unaided visual acuity of 6/6 or better and 24% had unaided acuity of 6/12 or worse. Six hundred twenty-five students (33%) failed the vision screening test and were referred for further examinations. The group which failed the vision screening test and had the highest rate of referral (46%) was the 11- to 12-year-old age group. The most common visual disorder was uncorrected myopia, accounting for 38% of the referrals (235 students). Only 26% of the sample were wearing a spectacle correction.
