Nutritional status, dietary intake patterns and nutrition knowledge of children aged 5-6 years attending kindergartens in the Klang Valley, Malaysia.

INTRODUCTION: Early childhood is a period during which many factors influence the development of lifelong eating habits. This study aimed to assess the nutritional status of young children and to determine factors related to eating habits. METHODS: A total of 992 children aged 5-6 years attending kindergartens that participated in the Bright Start Nutrition programme in the Klang Valley were included in the study. Anthropometric measurements were taken and body mass index (BMI) calculated. A questionnaire to assess the children's nutrition knowledge was administered through interviews, while their mothers self-administered another set of questionnaires regarding knowledge, attitude and practice on nutrition. RESULTS: The mean BMI was 15.7 +/- 2.7 kg/m2 in boys and 15.4 +/- 2.4 kg/m2 in girls. Based on the WHO 2007 growth reference, the prevalence of overweight and obesity were 9.1% and 9.3%, respectively; while the prevalence of thinness and stunting were 5.8% and 3.9%, respectively. Most of the children consumed breakfast (86.4%), lunch (94.1%) and dinner (93.4%) daily. The majority liked fruits (95.1%), snacks (93.8%), Western fast food (93.3%) and milk (90.8%), while less than two-thirds (65.1%) liked vegetables. The mean nutrition knowledge scores for the children and mothers were 73.2 +/- 9.8% and 60.2 +/- 18.8%, respectively. Maternal nutrition knowledge was correlated positively with children's vegetable intake (r=0.111, p<0.05) and negatively with snack intake (r = -0.134, p<0.05). CONCLUSION: These results showed a higher prevalence of overweight and obesity than underweight and thinness among the urban young children studied. As mother's nutrition knowledge was found to exert a positive influence on children's eating habits, it is important to provide nutrition education to both mothers and children when conducting intervention programmes.

A brief structured education programme enhances self-care practices and improves glycaemic control in Malaysians with poorly controlled diabetes.

We assessed the effectiveness of a brief structured diabetes education programme based on the concept of self-efficacy on self-care and glycaemic control using single-blind study design. One hundred and sixty-four participants with poorly controlled diabetes from two settings were randomized using computer-generated list into control (n = 82) and intervention (n = 82) groups, of which 151 completed the study. Monthly interventions over 12 weeks addressed the self-care practices of diet, physical activity, medication adherence and self-monitoring of blood glucose (SMBG). These self-care practices were assessed at Weeks 0 and 12 using pre- and post-questionnaires in both groups together with glycated haemoglobin A1c (HbA1c) and diabetes knowledge. In the intention-to-treat analysis (n = 164), the intervention group improved their SMBG (P = <0.001), physical activity (P = 0.001), HbA1c (P = 0.03), diabetes knowledge (P = <0.001) and medication adherence. At Week 12, HbA1c difference adjusted for SMBG frequency, medication adherence and weight change remained significant (P = 0.03) compared with control group. For within group comparisons, diabetes knowledge (P = <0.001), HbA1c level (P = <0.001), SMBG (P = <0.001) and medication adherence (P = 0.008) improved from baseline in the intervention group. In the control group, only diabetes knowledge improved (P = <0.001). These findings can contribute to the development of self-management diabetes education in Malaysia.

Dietary calcium and bone mineral density in premenopausal women with systemic lupus erythematosus.

The primary objective of this study was to determine the relationship between dietary calcium intake and bone mineral density (BMD) in premenopausal women with systemic lupus erythematosus (SLE) on corticosteroids (CS). The secondary aim was to identify other risk factors for osteoporosis in these patients. A cross-sectional sample of patients attending the SLE Clinic at a teaching hospital was recruited. BMD was measured using dual-energy X-ray absorptiometry. Daily dietary calcium intake was assessed using a structured validated food frequency questionnaire, in which patients were asked to estimate their food intake based on their recent 2-month dietary habits. Sixty subjects were recruited with a mean age of 33.70+/-8.46 years. The median duration of CS use was 5.5 years (range 0.08-24). The median cumulative dose of steroids was 17.21 g (range 0.16-91.37). The median daily dietary calcium intake was 483 mg (range 78-2101). There was no significant correlation between calcium intake and BMD, even after correcting for CS use. There were also no correlations between BMD and the duration of SLE, cumulative CS use, duration of CS use, smoking, alcohol intake, and SLE disease activity index score. Twenty-eight (46.7%) patients had normal BMD, 28 (46.7%) had osteopenia, and four (6.6%) had osteoporosis. Duration of SLE significantly correlated with cumulative CS dosage. In conclusion, 6.7% of these Asian premenopausal SLE women had osteoporosis and only 46.7% had normal BMD. Daily dietary calcium intake did not correlate with BMD.

Obesity in Malaysia.

This study was undertaken to assess the recent data on Malaysian adult body weights and associations of ethnic differences in overweight and obesity with comorbid risk factors, and to examine measures of energy intake, energy expenditure, basal metabolic rate (BMR) and physical activity changes in urban and rural populations of normal weight. Three studies were included (1) a summary of a national health morbidity survey conducted in 1996 on nearly 29 000 adults > or =20 years of age; (2) a study comparing energy intake, BMR and physical activity levels (PALs) in 409 ethnically diverse, healthy adults drawn from a population of 1165 rural and urban subjects 18-60 years of age; and (3) an examination of the prevalence of obesity and comorbid risk factors that predict coronary heart disease and type 2 diabetes in 609 rural Malaysians aged 30-65 years. Overweight and obesity were calculated using body mass index (BMI) measures and World Health Organization (WHO) criteria. Energy intake was assessed using 3-d food records, BMR and PALs were assessed with Douglas bags and activity diaries, while hypertension, hyperlipidaemia and glucose intolerance were specified using standard criteria. The National Health Morbidity Survey data revealed that in adults, 20.7% were overweight and 5.8% obese (0.3% of whom had BMI values of >40.0 kg m(-2)); the prevalence of obesity was clearly greater in women than in men. In women, obesity rates were higher in Indian and Malay women than in Chinese women, while in men the Chinese recorded the highest obesity prevalences followed by the Malay and Indians. Studies on normal healthy subjects indicated that the energy intake of Indians was significantly lower than that of other ethnic groups. In women, Malays recorded a significantly higher energy intake than the other groups. Urban male subjects consumed significantly more energy than their rural counterparts, but this was not the case in women. In both men and women, fat intakes (%) were significantly higher in Chinese and urban subjects. Men were moderately active with the exception of the Dayaks. Chinese women were considerably less active than Chinese men. Chinese and Dayak women were less active than Malay and Indian women. In both men and women, Indians recorded the highest PALs. Hence, current nutrition and health surveys reveal that Malaysians are already affected by western health problems. The escalation of obesity, once thought to be an urban phenomenon, has now spread to the rural population at an alarming rate. As Malaysia proceeds rapidly towards a developed economy status, the health of its population will probably continue to deteriorate. Therefore, a national strategy needs to be developed to tackle both dietary and activity contributors to the excess weight gain of the Malaysian population.

Location of the ureters in relation to the uterine cervix by computed tomography.

OBJECTIVE: Our aim was to determine the distance of the ureter from the cervix and the influence of age and weight on this distance. STUDY DESIGN: The distance of the ureter from the uterine cervix was determined by evaluating the computed pelvic tomograms from 52 women. Age and body mass index were compared to this distance by means of regression analysis. RESULTS: At the most dorsal reflection of the ureter, the average distance from ureter to cervical margin was 2.3 +/- 0.8 cm (range, 0.1-5.3 cm). There was no relationship to age, but there was a linear relationship between this distance and body mass index (R2 = 0.075; P = .049); thus the ureter was slightly more proximal to the cervical margin in heavier women. CONCLUSIONS: In women with apparently normal pelvic anatomy, the average distance between the ureter and cervix is >2 cm. The finding that this distance is <0.5 cm in 12% of the women studied may explain the relatively common occurrence of ureteral injury during hysterectomy. The relationship between body mass index and location is clinically insignificant.

Location of the transverse colon in relationship to the umbilicus: implications for laparoscopic techniques.

STUDY OBJECTIVE: To establish the location of the transverse colon in relationship to the umbilicus, and determine if it varies as a function of patient height or weight. DESIGN: Retrospective review of computed tomograms (CT) of the abdomen (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: Sixty-seven women with normal abdominal anatomy. INTERVENTION: Review of abdominal CT scans. MEASUREMENTS AND MAIN RESULTS: The relative relationships of the transverse colon and umbilicus were compared with age, height, weight, and body mass index (BMI = kg/m2) using multiple regression analysis. Average location of the superior margin of the transverse colon was 4.6 cm (95% CI 3.5-5.7 cm) above the umbilicus. In nine (13%) women it was below the umbilicus. The colon was below the umbilicus in 25% of nonobese women (BMI <25 kg/m2). CONCLUSION: Because the transverse colon lies below the umbilicus in more than 10% of women, injury to it may be an uncommon yet unavoidable complication of laparoscopy.

Canine model of acute aortic rupture: treatment with percutaneous delivery of a covered Z stent--work in progress.

PURPOSE: To develop a percutaneous treatment for aortic rupture with use of a covered intraluminal stent. MATERIALS AND METHODS: A transmural tear was created percutaneously in the thoracic aorta in six dogs with use of a 4-mm angioplasty balloon. Gianturco Z stents were covered with polytetrafluoroethylene, loaded into a 14-F sheath, and advanced through the femoral artery to the site of injury. Within 2 minutes after initiation of the injury, the stent was deployed. Homologous canine blood was given during the procedure. Dogs that survived 24 hours were then killed. RESULTS: The first stent did not expand completely, and the dog died in 1 hour. At necropsy, the first two dogs (1-hour and 8-hour survival) had a large left hemothorax and extensive periaortic hematoma, indicating intrathoracic exsanguination. The next four dogs were treated with a modified stent and survived 2 hours (n = 1), 8 hours (n = 1), and 24 hours (n = 2). At necropsy hemothorax did not exceed 15 mL, and periaortic hematomas were small. The cause of death in the two early casualties with the modified stent is uncertain. There were no signs of spinal cord injury despite occlusion of three pairs of intercostal arteries. CONCLUSION: The covered Z stent (in its modified form) tamponaded the aortic tear, preventing exsanguination. Long-term studies of biocompatibility of this device appear justified.
