Psychosocial Determinants of Childbirth Fear Among Asian Women: A Scoping Review
Background: Fear of childbirth (FOC) or tokophobia has a detrimental impact on women during and after pregnancy. Childbirth fear is multidimensional and may differ across nations and cultures. We aimed to determine the psychosocial determinants of tokophobia among Asians. Methods: We conducted a systematic literature search using the PubMed, Scopus, and Web of Science databases in September 2023. Included were original English-language articles that focused on Asian cohorts. We identified independent variables associated with maternal childbirth fear based on multivariable logistic and linear regression analysis. Results: Twenty-three studies are discussed in this review. We categorized the factors into (1) psychiatry, (2) psychology, (3) perception and experience, (4) relationships and support, (5) spirituality, and (6) COVID-19. The studies involved 10,538 women with overall FOC prevalence ranging between 56.6% to 82.1%. Maternal history of psychiatric disorder, depression, and anxiety were positive predictors of childbirth fear. Childbirth self-efficacy protects Asian mothers against tokophobia. A reduced level of fear was associated with higher maternal psychological and spiritual well-being, as well as stronger maternal resilience. Spousal and social support alongside good family function were shown to exert a protective effect against childbirth fear. Intimate partner abuse was associated with an increased risk of tokophobia in women. Studies during the pandemic indicated that maternal fear, obsession, and anxiety about COVID-19 were positively correlated to fear of childbirth. Conclusions: Childbirth fear among Asian women is greatly influenced by various psycho-social factors. More culturally driven research is needed to help develop relevant interventions that will enhance maternal psychological and spiritual well-being and reduce the fear of childbirth.

4 vs 7 points self-monitoring blood glucose in gestational diabetes mellitus on diet modification: randomised clinical trial in a single tertiary centre in Malaysia
Purpose There is no standardized best method on monitoring of patients with gestational diabetes on diet modification in the country. This study aims to investigate the optimum method of self-monitoring blood glucose. Methods This is a randomized clinical trial in a single tertiary centre involving patients with gestational diabetes mellitus (GDM) diagnosed based on NICE guideline on diet modification. The patients are randomized in 1:1 ratio to 4 or 7 points self-monitoring blood glucose. The monitoring was required to be done monthly with ultrasound for fetal growth. Blood was taken at recruitment for measurement of serum HbA1c and fructosamine. Results A total of 200 patients were recruited. There were significantly more Malay patients in the 7 points group (88.9% vs 78.2%, p = 0.033). Multiparous patients were significantly more in the 4 points group (82.2% vs 68.7%, p = 0.033). Both groups were similar in clinical characteristics. There was no statistical difference in the neonatal outcome particularly fetal macrosomia and admission to neonatal intensive care unit. Conclusions In patients with GDM on diet modification, self-blood glucose monitoring using either 4 or 7 points resulted in similar maternal and perinatal outcomes. The research was registered under ClinicalTrials.gov (NCT04101396) on 17/9/2019 (https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S00098EN&selectaction=Edit&uid=U0004RD4&ts=2&cx=-qlk1w2).

Comparison of Pregnancy Outcome between 4 and 6 cm Cervical os Dilatation to Demarcate Active Phase of Labour: A Cross-Sectional Study
This is a cross-sectional study comparing pregnancy outcomes between participants with 4 and 6 cm of cervical os dilatation at the diagnosis of the active phase of labour. It was conducted in a single tertiary centre involving low-risk singleton pregnancies at or beyond 37 weeks with spontaneous onset of labour. A total of 155 participants were recruited, 101 in group 1 (4 cm) and 54 in group 2 (6 cm). Both groups were similar in mean maternal age, mean gestational age at delivery, ethnicity, median haemoglobin level at delivery, body mass index, and parity. There were significantly more participants in group 1 who needed oxytocin augmentation (p < 0.001) for the longer mean duration (p = 0.015), use of analgesia (p < 0.001), and caesarean section rate (p = 0.002). None of the women had a postpartum haemorrhage or a third-or fourth-degree perineal tear, and none of the neonates required admission to the neonatal intensive care unit. There were significantly more nulliparas who had a caesarean section as compared to multiparas. A cervical os dilatation of 6 cm reduces the risk of caesarean section by 11% (95% CI, 0.01-0.9) and increases three times more the need for analgesia (AOR = 3.44, 95% CI, 1.2-9.4). In conclusion, the demarcation of the active phase of labour at a cervical os dilatation of 6 cm is feasible without an increase in maternal or neonatal complications.

Split Tummy Exercise Program for Reducing Diastasis Recti in Postpartum Primigravidae: A Randomized Controlled Trial
Background: Diastasis rectus abdominis (DRA) involves the separation of the midline abdominal muscles and linea alba and affects more than half of postpartum women. This study aimed to assess the effect of a split tummy exercise program (STEP) on DRA closure in postpartum mothers.Methods: A randomized controlled trial was conducted from 2008 to 2020 at the Obstetrics and Gynaecology Clinic of the Universiti Kebangsaan Malaysia Medical Centre. Primigravida mothers diagnosed with DRA were selected and randomly assigned to the intervention (n=21) or control (n=20) group. The intervention group underwent a home-based STEP consisting of three phases of nine abdominal exercises. DRA size was assessed at baseline and at 8 weeks postpartum using two-dimensional ultrasound.Results: The mean age of the participants was 28 years (standard deviation, 3.6), with the majority of Malay ethnicity (87.8%) and working mothers (78%). After 8 weeks, the intervention group showed a significant reduction in DRA size of up to 27% (mean difference, 6.17 mm; 95% confidence interval, 3.7–8.7; P<0.001). No significant intergroup DRA changes were observed after 8 weeks of follow-up.Conclusion: Early postpartum screening for DRA should be advocated to allow early STEP intervention to ensure favorable outcomes. STEP intervention is an effective postnatal training program for managing DRA.

Psychometric Evaluation of the Malay Version of the Childbirth Experience Questionnaire (CEQ-My)
Negative childbirth experience may cause adverse psychological effects in postpartum mothers. The Childbirth Experience Questionnaire (CEQ) is a multidimensional tool designed to assess women’s perceptions of labour and birth. We aim to validate the Malay version of the CEQ (CEQ-My) and evaluate its psychometric properties. The previously published Malay-translated CEQ was reviewed by a panel of experts and underwent minor changes. The original visual analogue scoring (VAS) was changed to a numerical scale. The reliability and construct validity of CEQ-My was assessed using Cronbach’s alpha and exploratory analysis, respectively. Known-groups validation was conducted using the Mann–Whitney U test, whilst the inter-item correlations between CEQ-My and its subdomains were evaluated through Spearman’s correlation. The final analysis involved 246 women. The questionnaire was easy to understand and all women preferred numeric scoring to the VAS. Based on the principal component factor analysis, we deleted one item and rearranged the domain for four items. The twenty-one items CEQ-My demonstrated good reliability with Cronbach’s alpha of 0.77. Women who had spontaneous vaginal delivery demonstrated significantly greater CEQ-My scores than those who underwent operative delivery (p = 0.002). The domain of professional support was positively correlated to that of own capacity and participation (p-value of < 0.001 and 0.002, respectively). The CEQ-My is a valid and reliable instrument to assess Malaysian women’s childbirth experiences. The easy-to-use electronic version of CEQ-My will improve future research and ease data collection.

Levator ani muscle avulsion: Digital palpation versus tomographic ultrasound imaging
Objective: To determine the diagnostic performance of digital palpation of levator ani muscle (LAM) avulsion compared with translabial tomographic ultrasound imaging (TUI).Methods: A cross‐sectional study, incorporating 195 women involved in a longitudinal cohort study. Palpation for levator integrity was performed, followed by a four‐dimensional translabial ultrasound. LAM avulsion defects were diagnosed in the presence of puborectalis muscle detachment from its insertion. Post‐processing analysis of ultrasound volumes for LAM integrity on TUI was performed blinded against palpation findings. Agreement between methods was assessed using Cohen's κ.Results: In all, 388 paired assessments of LAM bilaterally, were available. Sixteen (8.2%) unilateral avulsion defects were detected on palpation. Sonographically, 31 (16%) were diagnosed with avulsions: 4.6% bilateral and 11.3% unilateral. An overall agreement of 91% was observed between digital palpation and TUI, yielding a Cohen's κ of 0.32 (95% confidence interval 0.15–0.48) demonstrating “fair agreement”: and implying 25% sensitivity, 98% specificity, 63% positive predictive value, and 92% negative predictive value. Analysis of the first and last 20 palpations showed no change in performance during the 13‐day study period.Conclusion: Assessment of LAM avulsion defects by digital palpation is feasible but may require substantial training. Confirmation by imaging is crucial, especially if the diagnosis of avulsion may influence clinical management.

Validation of the Malay version of the p-QOL questionnaire
Introduction This study aimed to translate and validate the P-QOL questionnaire in the Malay language. Methods The P-QOL questionnaire was translated into the Malay language and subsequently back-translated to English. Test-retest reliability and internal consistency were tested. All patients who visited the gynecology outpatient clinic of UKMMC, UMMC and IIUM between January 2016 and May 2017 completed the P-QOL questionnaires and were assessed for POP-Q staging. Results One hundred twenty patients with symptomatic pelvic organ prolapse and 180 asymptomatic patients were included. The Cronbach’s alpha for each domain was > 0.70, which confirmed that there was a highly acceptable internal consistency. The value varied between 0.88 (role limitation) and 0.912 (sleep/energy). Test-retest reliability showed a significant correlation between the total scores for each domain (p < 0.001). There was a significant correlation between P-QOL domain scores and vaginal examination findings (POP-Q). With a higher POP-Q stage, a higher impact on the quality of life was detected in symptomatic patients. The total scores from all domains were significantly higher in symptomatic patients. Conclusion The Malay translated version of the P-QOL questionnaire is a reliable, consistent, and valid instrument for assessing the severity of the symptoms and impact on the quality of life among women with uterovaginal prolapse. It is easily understood, administered, and self-completed by patients.
