Analysis of routinely collected data: determining associations of maternal risk factors and infant outcomes with gestational diabetes, in Pakistani, Indian, Bangladeshi and white British pregnant women in Luton, EnglandThis study aims to compare the prevalence of gestational diabetes in Indian, Pakistani, Bangladeshi and British women in Luton, England and further examine associations in maternal risk factors (age BMI, smoking status and birth outcome), with gestational diabetes, with maternal ethnicity. A retrospective analysis using routinely collected secondary data from Ciconia Maternity information System (CMiS), between 2008 and 2013. The ethnicity of women recorded as Indian, Pakistani, Bangladeshi and white British, residing in [removed] were included in the study. The outcomes for n=15,211 cases were analysed using adjusted standardised residuals, Pearson Chi-square, frequencies and percentages of women with gestational diabetes. = 43.1 df=4, p<0.001) and an early gestational age at delivery (24-37 weeks) (χ2= 4.084 df=1, p=0.043). There are important differences in the prevalence rates of gestational diabetes which varied by maternal ethnicity. Of the women who had GDM, 48.7% were Pakistani, compared with 28.3% Bangladeshi, 16.4% white British and 6.6% Indian. It is essential policy makers and service providers target GDM screening and associated interventions and future research seeks to understand the reasons behind these differences.
A comparison of antenatal classifications of 'overweight' and 'obesity' prevalence between white British, Indian, Pakistani and Bangladeshi pregnant women in England; analysis of retrospective dataBackground: Maternal obesity increases women's risk of poor birth outcomes, and statistics show that Pakistani and Bangladeshi women (who are born or settled) in the UK experience higher rates of perinatal mortality and congenital anomalies than white British or white Other women. This study compares the prevalence of maternal obesity in Indian, Pakistani, Bangladeshi and white British women using standard and Asian-specific BMI metrics.Method: Retrospective cross-sectional analysis using routinely recorded secondary data in Ciconia Maternity information System (CMiS), between 2008 and 2013. Mothers (n = 15,205) whose ethnicity was recorded as white British, Bangladeshi, Pakistani or Indian. Adjusted standardised residuals and Pearson Chi-square. Main outcome measures: Percentage of mothers stratified by ethnicity (Indian, Pakistani, Bangladeshi and white British) who are classified as overweight or obese using standard and revised World Health Organisation BMI thresholds.Results: Compared to standard BMI thresholds, using the revised BMI threshold resulted in a higher prevalence of obesity: 22.8% of Indian and 24.3% of Bangladeshi and 32.3% of Pakistani women. Pearson Chi-square confirmed that significantly more Pakistani women were classified as `obese' compared with white British, Indian or Bangladeshi women (X-2 = 499,88 df = 9, p < 0.001).Conclusions: There are differences in the prevalence of obese and overweight women stratified by maternal ethnicity of white British, Indian, Pakistani and Bangladeshi. Using revised anthropometric measures in Indian, Pakistani and Bangladeshi women has clinical implications for identifying risks associated with obesity and increased complications in pregnancy.
Differences in the pregnancy gestation period and mean birth weights in infants born to Indian, Pakistani, Bangladeshi and white British mothers in Luton, UK: a retrospective analysis of routinely collected dataObjective To compare mean birth weights and gestational age at delivery of infants born to Indian, Pakistani, Bangladeshi and white British mothers in Luton, UK. Design Retrospective analysis using routinely recorded secondary data in Ciconia Maternity information System, between 2008 and 2013. Setting Luton, UK. Participants Mothers whose ethnicity was recorded as white British, Bangladeshi, Pakistani or Indian and living in Luton, aged over 16, who had a live singleton birth over 24 weeks of gestation were included in the analysis (n=14 871). Outcome measures Primary outcome measures were mean birth weight and gestational age at delivery. Results After controlling for maternal age, smoking, diabetes, gestation age, parity and maternal height and body mass index at booking, a significant difference in infants’ mean birth weight was found between white British and Indian, Pakistani and Bangladeshi infants, F(3, 12 287)=300.32, p<0.0001. The partial Eta-squared for maternal ethnicity was η2=0.067. The adjusted mean birth weight for white British infants was found to be 3377.89 g (95% CI 3365.34 to 3390.44); Indian infants, 3033.09 g (95% CI 3038.63 to 3103.55); Pakistani infants, 3129.49 g (95% CI 3114.5 to 3144.48); and Bangladeshi infants, 3064.21 g (95% CI 3041.36 to 3087.06). There was a significant association in preterm delivery found in primipara Indian mothers, compared with Indian mothers (Wald=8.192, df 1, p<0.005). Conclusions Results show important differences in adjusted mean birth weight between Indian, Pakistani, Bangladeshi and white British women. Moreover, an association was found between primipara Indian mothers and preterm delivery, when compared with Pakistani, Bangladeshi and white British women.
A qualitative study exploring the experiences of bereavement after stillbirth in Pakistani, Bangladeshi and White British mothers living in Luton, UKThis study aims to explore the experiences of bereavement after stillbirth of Pakistani, Bangladeshi and White British mothers in a town with multi-ethnic populations in England. A purposive sample of Pakistani, Bangladeshi and White British mothers aged over 16 (at time of infant birth), who suffered a stillbirth in the preceding 6-24 months and residing in a specified postcode area were invited to take part in the study, by an identified gatekeeper (audit midwife) from the local National Health Service Trust, in addition to local bereavement charities. Qualitative methods using face-to-face semi-structured interviews were undertaken, recorded and transcribed verbatim. Using framework analysis, several themes were identified. There were three main themes identified from the data; 1. knowledge and information of pregnancy and perinatal mortality; 2. attitudes and perceptions to pregnancy and perinatal mortality and 3. experiences with maternity care. The findings revealed mostly similarities in the bereavement experiences of the Pakistani, Bangladeshi and White British mothers. A few cultural and religious differences were identified. This study found important similarities in bereavement experiences of Pakistani, Bangladeshi and White British mothers and highlights considerations for policy makers and maternity services in how the timing of bereavement after care is provided, including advice surrounding the infant post-mortem.
