    State planning plays a central role in Malaysia's social and economic development. The government's rural development policies are designed to promote agricultural incomes and help counterbalance ethnic inequalities. The Federal Land Development Authority (FELDA) implements one of the internationally most successful land development and resettlement programs. In this article, we quantify the impact of FELDA settlements on local out-migration rates, linking macro and micro approaches and using data from the Malaysian Family Life Survey, national censuses, and other sources. A model of instantaneous migration rates specifies an individual's migration rate as a function of individual-level sociodemographic characteristics, the level of urbanization of the origin and destination, and the extent of rural development at the district of current residence. Our results show that in the late 1960s and early 1970s, the existence of rural development centers in a district reduced the levels of out-migration to pre-1965 levels.

    BACKGROUND: The prevalence and morbidity of asthma vary greatly among different ethnic communities and geographical locations, but the roles of environmental and genetic factors are not fully understood. The differences in prevalence of adult asthma among Chinese, Malay, and Indian ethnic groups in Singapore were examined, and the extent to which these could be explained by personal and environmental factors were investigated.
    METHODS: A stratified disproportionate random sample (n = 2868) of Chinese (n = 1018), Malays (n = 967), and Indians (n = 883) of both sexes was drawn from households in five public housing estates, and an interviewer administered questionnaire was used to determine cumulative and current prevalence of "physician diagnosed asthma" (symptoms with a physician diagnosis of asthma).
    RESULTS: Lifetime cumulative prevalence (standardised to the general population) of "physician diagnosed asthma" was 4.7% in men and 4.3% in women; 12 month period prevalences were 2.4% and 2.0%, respectively. Cumulative prevalence of asthma was significantly higher in Indians (6.6%) and Malays (6.0%) than in Chinese (3.0%); period prevalences of asthma were 4.5% in Indians, 3.3% in Malays, and 0.9% in Chinese. Ownership of cats or dogs was more frequent in Malays (15.4%) and Indians (11.2%) than in Chinese (8.8%). Rugs and carpets were also more frequently used by Malays (52.2%) and Indians (40.7%) than by Chinese (8.9%). Current smoking prevalences were higher in Malays (27.3%) than in Indians (19.4%) and Chinese (23.0%). Malays and Indians did not have higher rates of atopy (11.1% and 15.2%, respectively) than Chinese (15.4%). Adjustment for these factors in multivariate analyses reduced the greater odds of asthma in Malays and Indians, but not to a significant extent.
    CONCLUSIONS: There are ethnic differences in the prevalence of asthma in Singapore which are not entirely explained by differences in smoking, atopy, or other risk factors. Other unmeasured environmental factors or genetic influences are likely to account for residual differences in the prevalence of asthma.

    Data from the 1984 Malaysian Population and Family Survey were matched with birth registration records for 1985-87 to determine the accuracy of statements regarding desired family size that were reported in a household survey in predicting subsequent reproductive behavior. The findings of this study were that stated fertility intention provides fairly accurate forecasts of fertility behavior in the subsequent period. In other words, whether a woman has another child is predicted closely by whether she wanted an additional child. Informational, educational, and motivational activities of family planning programs would, therefore, have greater success in reducing family size if fertility intentions were taken into account.

    A case-control study of antecedents of neonatal septicaemia was performed using 50 cases of neonatal septicaemia and 73 comparison infants from a Malaysian hospital nursery. Multivariate analysis indicated the following independent risk factors: maternal primiparity, pre-eclampsia, prolonged rupture of membranes, twin pregnancy, prematurity, assisted ventilation, umbilical catheterization, and formula feeding. Although the spectrum of causative organisms varied between our study and past studies from Western countries, the risk factors for developing neonatal septicaemia were strikingly similar. Therefore, preventative guidelines based on risk factors described in Western countries, should help reduce the incidence of neonatal septicaemia at this Malaysian hospital.

    We interviewed 282 histologically confirmed cases of nasopharyngeal carcinoma (NPC) in Chinese residents of Selangor and the Federal Territory, Malaysia, and an equal number of Chinese age-, sex-, and length-of-residence-matched controls sampled from the general population. Consumption of 55 dietary items during childhood, and 5 years pre-diagnosis of NPC, was analyzed by univariate and multivariate methods. Four salted preserved foods (fish, leafy vegetables, egg and root), fresh pork/beef organ meats and beer and liquor consumption exhibited strong positive associations, and 4 vegetable/fruit combinations strong negative associations with NPC. Factor analysis and multivariable modeling using estimated factor scores strongly supported separate effects on NPC of vegetables/fruits, salted preserved foods, pork/beef organ meats and beer/liquor consumption. Multivariable modeling associated NPC most clearly with high consumption of salted fish, salted eggs, pork/beef liver and beer and low consumption of Chinese flowering cabbage, oranges/tangerines and shrimp. A strong residual association of social class with NPC remained after adjustment for diet, which is consistent with a substantial role for non-dietary environmental factors.

    This study aims to determine the prevalence of and risk factors associated with retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants. All premature VLBW infants, admitted into the neonatal intensive care unit of the University Hospital Kuala Lumpur, were screened from 4 weeks of life. Perinatal and neonatal data were retrieved from the infants' medical notes. Between August 1994 and July 1996, 100 infants had their eyes examined serially. Of the 15 (15%) infants with ROP, all were less than 31 weeks gestation, and only 1 infant had birth weight above 1250 g. Five (5%) infants had severe ROP; 4 infants underwent cryotherapy for stage 3 threshold disease. Infants with ROP, as compared to infants without ROP, had lower birth weight [mean (SEM) 993 (50) g versus 1205 (22) g, P < 0.001], lower gestational age [mean (SEM) 28.0 (0.4) weeks versus 30.1 (0.2) weeks, P < 0.001], higher rates of patent ductus arteriosus and chronic lung disease, greater number of radiographic examinations and episodes of late-onset suspected/confirmed sepsis, and required longer duration of supplemental oxygen, ventilation, xanthine, antibiotics and intralipid use, but were slower to establish full enteral feeds. On multivariate logistic regression analysis, birth weight < or = 1000 g [OR 2.38, 95% CI 1.25, 4.55, P = 0.009] and gestational age < or = 28 weeks [OR 2.86, 95% CI 1.47, 5.56, P = 0.002] were significant predictors of increased risk of this disease. In conclusion, ROP is strongly associated with smaller, more immature and sicker neonates. Prevention of prematurity would help reduce the incidence of this disease.

    We determined the allelic (X+/X-, M+/M-, and E+/E-) distribution frequencies of the XbaI, MspI, and EcoRI restriction fragment length polymorphisms (RFLPs) in the apolipoprotein B gene in a control group of 374 healthy Chinese, Malays, and Indians and in a hyperlipidemic cohort of 131 Chinese patients. Covariability between the RFLPs and serum lipid, lipoprotein, and apolipoprotein concentrations was also studied. We found a lower frequency (average 0.0829) of the X+ allele and higher frequencies of the E+ (average 0.9452) and M+ (average 0.9772) alleles in our study population compared with frequencies reported in other populations. The 3 polymorphic sites did not contribute to significant variations in lipid levels (p > 0.1 in all cases). Also, there was no significant variation in genotype frequencies between the control subjects and the hyperlipidemic subjects. Despite their relative close proximity within the APOB gene sequence, the 3 polymorphic sites did not show any significant linkage disequilibrium. However, the presence of the X+ cutting site was in linkage disequilibrium with the Del allele of the 5' insertion-deletion polymorphism and the E-allele was in linkage disequilibrium with the 3' VNTR located near the 3' end of the coding region of the APOB gene.

    The increased development of hospital services in Hong Kong over the last decade has given rise in the demand for more recruits to join the nursing profession. Despite the advancement in education and the improvement in the working conditions, the problems of attracting sufficient new recruits remain critical. This study aimed to examine high school students' attitudes towards the nursing profession and to identify the contributing factors affecting shortage of nurses within the context of Hong Kong. A convenience sample of 375 high school students was recruited. A questionnaire was used to measure their knowledge, attitudes and intention to study nursing. Descriptive and inferential statistics were used to describe their career preferences and to compare knowledge, attitudes and intention scales between gender and nursing exposure groups. Results indicated that the students were generally knowledgeable about nursing but were reluctant to pursue nursing as a career. However, students who were socially acquainted with a nurse demonstrated a slightly more positive attitude towards nursing and slightly higher intention to pursue nursing as a career compared with those having no social acquaintance with a nurse. Implications for promotion of nursing profession and limitations of the study were discussed.

    The presenting features and treatment outcome for 575 Malaysian children (< or = 12 years of age) with newly diagnosed acute lymphoblastic leukemia (ALL), admitted to the University Hospital, Kuala Lumpur, Malaysia between 1 January 1980 and 30 May 1995 were evaluated to determine their prognostic significance. Two-year overall survival was achieved in 67 per cent of all patients and 55 per cent of patients were relapse-free at 2 years. All except 10 patients, with identified French-American-British L3 morphology were treated with the modified Berlin-Frankfurt-Munster 78 treatment protocol. Univariate analyses of failure rate conferred age, sex, white cell count and hemoglobin level as potentially significant prognostic factors. All four presenting features retained their prognostic strength in a multivariate analysis. Race, platelet count, morphological subtype, liver/spleen size, lymphadenopathy, central nervous system and mediastinal mass involvement did not show any significant effect on treatment outcome. The 2-year survival rate was significantly different with regard to age, white cell count and hemoglobin level. However, sex was not significantly related to overall survival. These prognostic factors may have implications on future stratification of risk-adjusted initial treatment in the management of childhood ALL. Our analysis of Malaysian children is similar to what could be predicted based on previous studies in other populations.

    A survey was conducted to assess student's sexual knowledge and attitudes using a questionnaire based on the Sex Knowledge and Attitude Test (SKAT-II) to compare medical and nursing students with students (non-medical/nursing) who registered for a sexual health course. 85 Sexual Health, 115 medical and 81 nursing students voluntarily participated in the survey. This study showed that all the student groups showed relatively low scores in knowledge. Furthermore, average knowledge scores differed significantly between the three student groups with medical students scoring highest and nursing students lowest. Besides student groups, several other factors were found to be significantly associated with Knowledge score namely, race, religion, age, perception of the importance of religion and the extent to which religious beliefs influence sexual attitudes. Furthermore, multivariate statistical analyses showed that among these factors, student group, race/religion and religious importance were significant predictors of sexual knowledge. Specifically, being a medical student was associated with higher scores relative to a non-medical student, being a Malay student was independently associated with a lower average score compared to other races, and perceiving religion as extremely important was associated with a lower score.

    OBJECTIVE: Empirical antibiotic treatment for febrile neutropenic patients has been the mainstay of treatment for many years. Beta-lactam antibiotics and aminoglycosides have been the most frequently used drug combination. The purpose of this study was to evaluate the efficacy, safety, tolerance and costs of single-daily ceftriaxone plus amikacin versus thrice-daily dose of ceftazidime plus amikacin.

    METHODOLOGY: One hundred and ninety-one episodes of fever and neutropenia in 128 patients from October 1997 to December 1998 were included in a prospective, open-label, single-centre study. Patients were randomly assigned to either treatment group and evaluated as successes or failures according to defined criteria. Daily assessments were made on all patients and all adverse events recorded. Univariate and multivariate analysis of outcomes and a cost analysis were carried out.

    RESULTS: There were 176 evaluable patient-episodes with 51.1% in the single-daily ceftriaxone-amikacin group and 48.9% in the ceftazidime-amikacin group. There were 50 positive blood cultures: 12 Gram-positive bacteria, 33 Gram-negative bacteria and five fungi. Pseudomonas aeruginosa (P. aeruginosa) accounted for 14% of total isolates. The overall success rate was 55.5% in the ceftriaxone group compared to 51.2% in the ceftazidime group (P = 0.56). Mean time to defervescence was 4.2 days in the single-daily group and 4.3 days in the thrice-daily group. There were nine infection-related deaths; five in the single-daily ceftriaxone group. The daily cost of the once-daily regime was 42 Malaysian Ringgit less than the thrice-daily regime. There was a low incidence of adverse effects in both groups, although ototoxicity was not evaluable.

    CONCLUSIONS: The once-daily regime of ceftriaxone plus amikacin was as effective as the 'standard' combination of thrice-daily ceftazidime and amikacin with no significant adverse effects in either group. The convenience and substantial cost benefit of the once-daily regime will be particularly useful in developing countries with limited health resources and in centres with a low prevalence of P. aeruginosa.

    A morphological and molecular analysis was undertaken with the objective of identifying markers for geographical populations of Old World screwworm flies, Chrysomya bezziana Villeneuve (Diptera: Calliphoridae). The morphological analysis involved 192 adult flies from 14 countries, and the molecular analysis involved 45 larvae or adults from 14 populations in 11 countries. Principal components and cluster analysis of 10 morphological characters indicated that flies from Papua New Guinea (PNG) were a distinct group and most similar to flies from nearby Asian islands (Java, Sabah). There was poor resolution of other geographical regions, but some support for clustering of flies from Africa or India. Cladistic analysis of mitochondrial DNA sequences gave strong support for recognizing two races of Old World screwworm, one from sub-Saharan Africa and the other from the Gulf region and Asia. This latter race could be further divided into two lineages, i.e. one from mainland Asia (from Iraq to the Malay Peninsula) and the other from two islands of PNG.

    BACKGROUND: The majority of colorectal cancers are still diagnosed in patients who present with symptoms especially in countries where colorectal screening programs are not practised. The aim of our study was to determine the predictive factors for colorectal cancer in patients referred for colonoscopy.

    METHODS: A prospective study of 485 consecutive patients who underwent colonoscopy during a 22-month period was performed. All patients answered a detailed questionnaire. Indications for colonoscopy and the findings were recorded.

    RESULTS: The mean age of the study population was 55.7 +/- 14.7 years. There were 221 (45.6%) males and 264 (54.4%) females. Sixty-five (13.4%) were Malays, 298 (61.4%) were Chinese and 112 (23.1%) were Indians. Multiple backward stepwise regression analysis revealed that independent predictors for colorectal cancer (odds ratio [95% CI]) were the presence of rectal bleeding (4.3 [4.0-8.0]) and iron deficiency anemia (4.0 [3.6-10.2]). In those aged 50 and over, male gender (4.5 [2.2-9.3]) and abdominal pain (3.1 [1.4-6.7]) were also significant positive predictors of cancer.

    CONCLUSIONS: With the ever-increasing demand for gastrointestinal endoscopy, the appropriate utilization of colonoscopy is essential to afford prompt patient evaluation. Our study supports the need to prioritize the use of colonoscopy in patients with rectal bleeding and iron deficiency anemia. In the older patient where the background prevalence of colorectal cancer is higher, referral for colonoscopy is also justified.

    The purpose of this study was to identify the early indicators of hemorrhage in severe dengue infections in 114 patients; 24 patients had severe hemorrhage and 92 had no hemorrhage. The platelet counts were not predictive of bleeding. The duration of shock (OR, 2.11; 95% CI, 1.13 to 3.92; P =.019) and low-normal hematocrit at the time of shock (OR, 0.72; 95% CI, 0.55 to 0.95; P =.020) were risk factors of severe hemorrhage.

    Malaysia had the second highest crude accident rate in the world until 1998. Most children who were involved in these road traffic accidents required intensive neurosurgical care management. We report a prospective study on 36 paediatric neurotrauma patients in rural North East West Malaysia who underwent uniform intensive therapy and were subsequently followed up over a period of 2 years. The modified paediatric Glasgow Coma Scale with support of the revised Wechlser Intelligence Scale for children was used to test the outcome of these children over a period of two years. All patients were managed aggressively in our intensive care as well as our high dependency units. Our results indicate that improvement in outcome is seen after a six month period. Midline shift, duration of coma and duration of transport were found to be significant variables associated with bad outcome. Other variables i.e. age, sex, Glasgow Coma Scale on admission and on site, and lesions of the dominant lobe were not found to be associated with good outcome in these patients.

    Objective: Lack of direct access to tertiary pediatric intensive care services in rural hospitals may be associated with poorer outcome among critically ill children. Inter-hospital transport by non-specialized teams may also lead to increased morbidity and even mortality. We therefore studied the outcome of children with different accessibility to tertiary pediatric care in Malaysia.

    Methods: We prospectively compared the Pediatric Risk of Mortality (PRISM II) adjusted standardized mortality ratio (SMR), unanticipated deaths and length of stay of 131 patients transported from rural hospitals (limited access) with 215 transferred from the casualty wards or other in-hospital wards (direct access) to a tertiary pediatric ICU.

    Results: The transported patients were younger than the in-hospital patients (median age 1.0 versus 6.0 months, p=0.000) and were more likely to have respiratory diseases. Other baseline characteristics did not differ significantly. Differences in access to tertiary intensive care from community hospitals was associated with an extended median length of stay (4.0 versus 2.0 days, p=0.000) but did not affect SMR (0.92 versus 0.84, rate ratio 1.09, 95% CI 0.57-2.01; p=0.348) or percentage of unexpected deaths (4.8% versus 2.8%, p=0.485). The adjusted odds ratio for mortality (1.7, 95% CI 0.7-4.3) associated with transfer was not statistically significant (p=0.248).

    Conclusions: The outcome of critically ill children transferred from community hospitals did not differ from that of those who develop ICU needs in the wards of a tertiary center, despite being transported by non-specialized teams. Outcome was not affected by initial inaccessibility to intensive care if the children finally received care in a tertiary center.

    The primary objective of this study was to determine the mean glandular dose (MGD) during diagnostic mammography in Malaysia. The secondary objective was to evaluate some of the factors affecting MGD. A survey of standard MGD was performed, based upon quality control records for the period October 1999 to August 2001. This covered 30 mammography units from 9 manufacturers. MGD was also measured for a series of patients attending mammography examinations at three other mammography units. MGD per film was estimated from recorded radiographic factors, the compressed breast thickness (CBT) and X-ray unit calibration data. MGD per woman was calculated by summing the MGDs for all films, and averaging it over both breasts. 300 women drawn equally from three major ethnic groups, namely Malay, Chinese and Indian, took part in the study. The difference of MGD per woman between ethnic groups was tested for significance using non-parametric Kruskal-Wallis and median tests. The factors affecting MGD per woman were tested for significance using a multivariate analysis of variance. The MGD for the phantom was 1.23 mGy (range 0.22-2.39 mGy) while the mean patient based MGD per film was 1.54 mGy and 1.82 mGy for the craniocaudal and mediolateral oblique views, respectively. The mean MGD per woman was 3.37 mGy. It was also found that there is no significant difference in MGD per woman among the ethnic groups (p>0.05, Kruskal-Wallis test). However, on the multivariate test two factors, namely half value layer of the X-ray beam and (CBT), had a significant effect on MGD per woman (p<0.05). No significant relationships were seen between MGD per woman with respect to ethnicity, body mass index or age.

    OBJECTIVE: To study the impact of various clinicopathological factors on short-term survival in a cohort of breast cancer patients treated at the University of Malaya Medical Centre (UMMC).
    METHODS: All cases of breast cancer treated at UMMC from January 1999 to June 2001, except for stage IV disease, were included in the study. Survival analysis was carried out using Kaplan-Meier for univariate analysis and Cox regression for multivariate analysis. The log-rank test was used to test the significance of differences between the different survival curves.
    RESULTS: A total of 385 patients were included. The mean patient age at presentation was 50.3 years (SD, 11.4); 198 (51.4%) patients had lymph node-positive disease, and 187 (48.6%) had node-negative disease. The mean follow-up period was 18.7 months (SD, 8.8). The Malay ethnic group, tumours of larger size, node-positive disease, more than five positive lymph nodes, oestrogen receptor (ER) negativity and the presence of lymphovascular invasion were significant prognostic factors for shorter recurrence-free survival (RFS) in the univariate analysis. In the multivariate analysis, ER negativity was the only independent adverse prognostic factor for RFS. For overall survival (OS), tumours of larger size, node-positive disease, more than five positive lymph nodes, ER negativity and high grade tumours were associated with significantly shorter OS. However, more than five positive lymph nodes was the only independent prognostic factor for shorter OS in the multivariate analysis. Further multivariate analysis of the patients with node-positive disease showed that the Malay ethnic group, ER negativity and more than five positive lymph nodes were independent prognostic factors for shorter RFS. On the other hand, ER negativity and more than five positive lymph nodes were independent negative prognostic factors for OS in this subgroup of patients.
    CONCLUSION: The evaluation of various prognostic factors would provide useful information on disease progression in local patients, especially for the planning of adjuvant therapies and follow-up protocols. Differences in the pattern of breast cancer among the different ethnic groups in Malaysia warrant further studies.
