INTRODUCTION: Hospitalised elderly patients are at high risk of malnutrition due to the presence of chronic diseases and inadequate food intake. It was on this premise that a Malnutrition Risk Screening Tool-Hospital (MRST-H) was developed for identifying the risk of malnutrition among Malaysian elderly patients.
METHODS: A total of 181 respondents aged 65 years and above who had been admitted to the Geriatric Ward of the University Malaya Medical Centre were recruited. The respondents' nutritional assessment was assessed using the Global Indicator of Malnutrition (GIM), a reference gold standard of malnutrition consisting of anthropometric measurements, biochemical indicators and the Subjective Global Assessment (SGA). Important predictive factors of malnutrition were determined by logistic regression analysis.
RESULTS: Five out of 18 predictive factors were significantly associated with malnutrition (p<0.05) in the final multivariate logistic regression model. These five factors were used to develop the MRST-H. Its validity was tested among 100 elderly inpatients in the Kuala Lumpur Hospital. The MRST-H was found to have 66.7% sensitivity, 96.2% specificity and 82.4% positive predictive value to GIM. The MRST-H was tested for reliability among 40 patients involving three raters (a dietitian and two nurses). The Kappa index of agreement was excellent between the dietitian with nurse A (81.3%, Kappa=0.84) and nurse B (87.5%, Kappa=0.89) respectively.
CONCLUSION: The MRST-H developed showed high validity and reliability as a screening tool for identifying hospitalised elderly patients with high risk of malnutrition.
A cross-sectional study was carried out to evaluate the nutritional status of 51 subjects with leukemia aged 4 to 12 years from the Haematology and Oncology Paediatric Ward, Universiti Kebangsaan Malaysia Medical Centre (PPUKM) and the Paediatric Institute of Kuala Lumpur. Nutritional status was assessed using anthropometric measurements, biochemical and haematological parameters. Subjects comprised 32 (62.7%) males and 19 (27.3%) females. Most of the subjects (41.2%) were in the age group of 4 to 6 years. More than half of the children were Malays (70.6%) followed by Indians (15.7%) and Chinese (13.7%). The subjects were diagnosed as acute lymphoblastic leukemia (ALL) (84.3%) followed by acute myelogenous leukemia (AML) (13.7%) and chronic myelogenous leukemia (CML) (2.0%) respectively. Most of the children were in remission status (54.9%). Underweight (
The aim of this study was to identify risk factors associated with osteoporosis in urban midlife Malaysian women and to assess the effectiveness of lifestyle intervention in bone loss prevention with hormone replacement therapy (HRT) as a positive control. A total of 514 disease-free, uterus-intact, non-HRT-using women aged 45 years and older were recruited into the study. After initial bone mineral density (BMD) assessments, they were randomized into three groups: GI (control), G2 (lifestyle intervention), and G3 (lifestyle intervention with HRT). The study group was composed of 67.5% Chinese, 27.8% Malay, and 4.2% Indians with a mean age of 51.07+/-5.28 years. Two-fifths were postmenopausal, and the prevalence of osteoporosis was 24.1%, seen predominantly at the hip. Postmenopausal women had significantly lower mean BMD and a higher incidence of osteoporosis compared with the premenopausal women, 42.1% vs. 11.1% (p<0.0005). A lower incidence of osteoporosis was found in women who took calcium supplementation regularly as opposed to those who do not, 18.7% vs. 29.3% (p=0.036). Age and a greater postmenopausal duration showed a significant negative association with BMD, whereas higher family income, weight, body mass index, and waist and hip circumference were positively correlated. After 18-20 months, the effect of intervention was assessed based on BMD values of 279 women at baseline and after intervention. Lifestyle intervention alone was effective in premenopausal women, preventing over 90% of spinal bone loss compared with the controls, who lost 11.6% (0.046 g/cm2) bone mass with similar losses of hip bone, 2.0% (0.026 g/cm2) vs. 1.5% (0.020 g/cm2). Premenopausal women on HRT also showed a substantial decrease in spine and hip BMD, 18.6% (0.081 g/cm2) and 9.0% (0.122 g/cm2), respectively. The lifestyle intervention program retarded postmenopausal bone loss by 21% and 37% compared with controls, who lost 9.6% (0.141 g/cm2) and 6.0% (0.138 g/cm2) bone mass at the spine and hip. In comparison, lifestyle intervention with HRT increased postmenopausal BMD by 12.7% (0.216 g/cm2) at the spine and 1.9% (0.042 g/cm2) at the hip. The changes in hip BMD were influenced by current age, ethnicity, and income, while intervention had the strongest effect on spine BMD changes. In conclusion, lifestyle intervention prevented spinal bone loss in premenopausal women and retarded postmenopausal spine and hip bone loss compared with controls. The benefits of physical activity on spine and hip BMD highlight its potential as a safe and cost-effective alternative to HRT, which is not advocated because of its potential adverse effects.
The objective of the study was to assess nutritional and health status as well as nutritional knowledge in urban middle-aged Malaysian women. The impact of menopause on diet and health indices was also studied. The study included 360 disease free women, non users of HRT,aged > or =45 years with an intact uterus recruited from November 1999 to October 2001. Personal characteristics, anthropometric measurements and blood sample were acquired followed by clinical examination. Nutrient intake and nutritional knowledge was determined by a quantitative FFQ and KAP. The findings showed that urban middle-aged women, aged 51.65+/-5.40 years had energy intakes (EI) 11% below RDA, consisting of 53% carbohydrates, 15% protein and a 32% fat which declined with age. The sample which comprised of 42.5% postmenopausal women had a satisfactory diet and healthy lifestyle practices. Premenopausal women consumed more dietary fat (6%) with other aspects of diet comparable to the postmenopausal women. Iron intake was deficient in premenopausal women, amounting to 56% RDA contributing to a 26% prevalence of anaemia. Overall, calcium intake reached 440 mg daily but dairy products were not the main source. The postmenopaused had a more artherogenic lipid profile with significantly higher total cholesterol (TC) and LDL-C, but more premenopausal women were overweight/obese (49% versus 35%). EI was the strongest predictor for BMI and waist circumference (WC), with WC itself an independent predictor of fasting blood sugar and TC with BMI strongly affecting glucose tolerance. High nutritional knowledge was seen in 39% whereas 20% had poor knowledge. Newspapers and magazines, followed by the subject's social circle, were the main sources of nutritional information. Nutritional knowledge was positively associated with education, household income, vitamin/ mineral supplementation and regular physical activity but inversely related to TC. In conclusion, middle-aged urban women had an adequate diet with low iron and calcium intakes. Nutritional knowledge was positively associated to healthier lifestyle practices and lower TC. A comparable nutrient intake and lifestyle between pre and postmenopausal women suggested that health changes associated with menopause was largely independent of diet.
