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.
Background Gestational diabetes mellitus (GDM) is a common medical complication in pregnancy. The aim of this study was to compare the prevalence of GDM using the World Health Organization (WHO) criteria and the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria in our population. We further compared the incidence of adverse maternal and neonatal outcomes in women diagnosed with GDM using these criteria and determined whether the IADPSG criteria is suitable in our population. Methods This randomized controlled trial was conducted at our antenatal clinic involving 520 patients from 1st February 2015 until 30th September 2017. They were randomized into the WHO and the IADPSG groups. All eligible women underwent a standard oral glucose tolerance test with 75 g glucose, their fasting and 2 h post prandial glucose levels were taken. The primary outcome was the prevalence of GDM. The secondary outcomes were the incidence of primary cesarean section, gestational hypertension or preeclampsia, preterm delivery <37 weeks, fetal macrosomia, neonatal hypoglycemia and shoulder dystocia or birth injury. Results The prevalence of GDM in both groups were similar (37.9% vs. 38.6%). GDM women in the WHO group had a significantly higher incidence of gestational hypertension or preeclampsia (p = 0.004) and neonatal hypoglycemia (p = 0.042). In contrast, GDM women in the IADPSG group had a significantly higher incidence of fetal macrosomia (p = 0.027) and cesarean section (p = 0.012). Conclusion The IADPSG diagnostic criteria for GDM may not be suitable for use in our population as it resulted in women being diagnosed later and being undertreated, thus leading to adverse maternal and neonatal outcomes.
Background Urinary retention and voiding dysfunction is a distressing event and relatively common in immediate postpartum period. This study aims at investigating the range of postvoid residual urine volume after vaginal delivery and its association with various obstetric parameters. Methods This was a prospective observational study of women who delivered vaginally in Universiti Kebangsaan Malaysia Medical Centre from March 2017 to September 2017. Those who were able to void within 6 hours after delivery, the voided volume measurements were taken at their second void followed by measurement of residual urine using a transabdominal ultrasound scan. For those unable to void at 6 hours postpartum, the bladder volume was measured. If the bladder volume was 500 ml or more, an indwelling catheter would be inserted and kept for 24 hours. Results A total of 155 patients who fulfilled the inclusion were recruited. There were 143 (92.3%) patients who had residual urine volume of less than 150 ml at second void. Out of these 143 patients, 138 (96.5%) had residual urine volume of less than 100 ml, and among the 138 patients, 119 (86.2%) had residual urine volume of less than 50 ml. The median residual urine volume was 10 ml (2, 42). The overall rate of postpartum urinary retention (PPUR) was 7.7%; 6 (3.85%) had overt retention and 6 (3.85%) had covert retention. Primiparity, duration of active phase of labour, duration of second stage of labour, epidural analgesia, episiotomy, instrumental delivery, and perineal pain score were independent risk factors associated with postpartum urinary retention. Conclusion Postpartum urinary retention complicates approximately 7.7% of vaginal deliveries. Majority (86.2%) of them had residual urine volume less than 50 ml. Obstetrics factors independently associated with PPUR include primiparity, duration of active phase of labour, duration of second stage of labour, epidural analgesia, episiotomy, instrumental delivery, and degree of perineal pain.
Background: To evaluate the knowledge, perception and attitudes towards human papilloma virus (HPV) among pre-university students in Malaysia. Study design : In this cross sectional study, between November 2013 to March 2014, in a public university, a convenient sampling method was used. A total of 716 respondents were recruited and interviewed with a set of standard questionnaires for assessment of knowledge, perception and attitudes towards HPV and predictor variables associated with level of knowledge. Results: Almost half (48.9%) of the respondents scored less than 5 and were categorised as having poor knowledge. Three hundred and twelve (43.6%) respondents had moderate knowledge and only 54 (7.5%) respondents exhibited good knowledge with the score of 11 and above. Only 142 (20%) students perceived themselves to be vulnerable to HPV infection though 560 (78.2%) students thought that HPV infection is a serious disease. Perceived benefits and desire to be vaccinated were significantly associated with gender (p=0.000) and knowledge of HPV vaccine and cervical cancer (p=0.000). Conclusions: The level of knowledge regarding HPV among the pre-university students was low. However, student intention for vaccination increased with increasing level of knowledge. Thus, efforts to improve knowledge and awareness should be prioritised to increase uptake of the HPV vaccination programme and hence reduce morbidity and mortality from consequences of HPV infection, including cervical carcinoma.
Objective To assess the efficacy of an exercise program towards reducing back pain in pregnant women. Methods In this prospective control study, 145 low risk pregnant women who scored more than 20 for functional limitation assessment were recruited. The severity of back pain was assessed using the visual analoque scale (VAS) and the functional limitation was assessed using the Oswestry disability questionnaire (ODQ). All participants were informed of back care measures and provided with Paracetamol as an adjunct analgesia. The intervention group will have a session with a trained physiotherapist. Subsequently, all participants will be required to fill in a similar questionnaire regarding pain intensity and functional limitation assessment after 6 weeks post-intervention. Results There was a significant reduction in the VAS score and improvement in functional ODQ score in the intervention group. The median usage of Paracetamol as an analgesia to control back pain in the control group was 500 mg higher than the intervention group. There was a weak association of age, parity, duration of back pain, and body mass index with functional ODQ score at 6 week following intervention. Conclusion The back pain exercise reducing program was effective in reducing back pain intensity and analgesia usage with a significant improvement in functional ability.
