Antenatal depression and anxiety and early pregnancy BMI among White British and South Asian women: retrospective analysis of data from the Born in Bradford cohort.

ABSTRACT: BACKGROUND:Maternal obesity has severe physical impacts such as increased chances of pre-eclampsia and gestational diabetes. However, mental health impacts are given less attention within antenatal care. Evidence suggests that women with obesity carry increased risk of maternal depression and anxiety, however, this association is not well researched amongst South Asian women in the UK who are vulnerable to both. The aim of this study was to investigate the association between antenatal depression and anxiety and early pregnancy BMI, within and between White British and South Asian women, using data from the Born in Bradford cohort. METHODS:Depression and anxiety were assessed using the General Health Questionnaire (GHQ); a GHQ score of >?0 for the depression subscale and?>?6 for anxiety. Mother's BMI was stratified into six World Health Organisation BMI categories (underweight, recommended, overweight or obese class 1-3). To determine associations, univariate and multivariate logistic regression models (adjusting for maternal age, education, deprivation and smoking) were used. RESULTS:There were 7824 women included (3514 White British and 4310 South Asian). South Asian women were more likely to have depression than White British (43.3% vs 36.1% p?

Project description:BackgroundDiagnosis of gestational diabetes predicts risk of infants who are large for gestational age (LGA) and with high adiposity, which in turn aims to predict a future risk of obesity in the offspring. South Asian women have higher risk of gestational diabetes, lower risk of LGA, and on average give birth to infants with greater adiposity than do white European women. Whether the same diagnostic criteria for gestational diabetes should apply to both groups of women is unclear. We aimed to assess the association between maternal glucose and adverse perinatal outcomes to ascertain whether thresholds used to diagnose gestational diabetes should differ between south Asian and white British women. We also aimed to assess whether ethnic origin affected prevalence of gestational diabetes irrespective of criteria used.MethodsWe used data (including results of a 26-28 week gestation oral glucose tolerance test) of women from the Born in Bradford study, a prospective study that recruited women attending the antenatal clinic at the Bradford Royal Infirmary, UK, between 2007 and 2011 and who intended to give birth to their infant in that hospital. We studied the association between fasting and 2 h post-load glucose and three primary outcomes (LGA [defined as birthweight >90th percentile for gestational age], high infant adiposity [sum of skinfolds >90th percentile for gestational age], and caesarean section). We calculated adjusted odds ratios (ORs) and their 95% confidence intervals (CIs) for a 1 SD increase in fasting and post-load glucose. We established fasting and post-load glucose thresholds that equated to an OR of 1·75 for LGA and high infant adiposity in each group of women to identify ethnic-specific criteria for diagnosis of gestational diabetes.FindingsOf 13,773 pregnancies, 3420 were excluded from analyses. Of 10,353 eligible pregnancies, 4088 women were white British, 5408 were south Asian, and 857 were of other ethnic origin. The adjusted ORs of LGA per 1 SD fasting glucose were 1·22 (95% CI 1·08-1·38) in white British women and 1·43 (1·23-1·67) in south Asian women (pinteraction with ethnicity = 0·39). Results for high infant adiposity were 1·35 (1·23-1·49) and 1·35 (1·18-1·54; pinteraction with ethnicity=0·98), and for caesarean section they were 1·06 (0·97-1·16) and 1·11 (1·02-1·20; pinteraction with ethnicity=0·47). Associations between post-load glucose and the three primary outcomes were weaker than for fasting glucose. A fasting glucose concentration of 5·4 mmol/L or a 2 h post-load level of 7·5 mmol/L identified white British women with 75% or higher relative risk of LGA or high infant adiposity; in south Asian women, the cutoffs were 5·2 mmol/L or 7·2 mml/L; in the whole cohort, the cutoffs were 5·3 mmol/L or 7·5 mml/L. The prevalence of gestational diabetes in our cohort ranged from 1·2% to 8·7% in white British women and 4% to 24% in south Asian women using six different criteria. Compared with the application of our whole-cohort criteria, use of our ethnic-specific criteria increased the prevalence of gestational diabetes in south Asian women from 17·4% (95% CI 16·4-18·4) to 24·2% (23·1-25·3).InterpretationOur data support the use of lower fasting and post-load glucose thresholds to diagnose gestational diabetes in south Asian than white British women. They also suggest that diagnostic criteria for gestational diabetes recommended by UK NICE might underestimate the prevalence of gestational diabetes compared with our criteria or those recommended by the International Association of Diabetes and Pregnancy Study Groups and WHO, especially in south Asian women.FundingThe National Institute for Health Research.

Project description:BackgroundChildren of South Asian (SA) origin in the UK have lower levels of physical activity (PA), compared to their White counterparts. Parents play an important role in establishing PA habits among young children. The aim of this study was to compare PA and television (TV) viewing parenting practices for young children between SA British (SAB) and White British (WB) parents living in the UK.MethodsWe conducted a secondary analysis of the Born in Bradford (BiB) 1000 study, using survey data at child ages 24 and 36 months. The study sample included three groups of mothers (n = 1,149): foreign-born SAB (n = 458), UK-born SAB (n = 276), and WB (n = 455). Mothers completed a survey about parenting practices (i.e., PA supports, PA restrictions, TV viewing restrictions) at child age 24 months and child PA and TV viewing behaviors at child ages 24 and 36 months. Parenting practices were compared among the three groups. Multivariable linear regression analyses compared children's weekly walking frequency and daily TV viewing hours by parenting practices in the three groups.ResultsThe foreign-born SAB group showed the lowest frequencies of PA-supportive parenting practices (verbal encouragement: 3.7 ± 3.1 times/week; logistic support: 1.5 ± 1.8 times/week) and the highest frequencies of PA-restrictive parenting practices (7.8 ± 7.7 times/week) among the three groups (p < 0.01). Children of Foreign-born SAB mothers had the most frequent TV watching during a mealtime (4.0 ± 3.1 times/week) among the three groups (p < 0.01). Less frequent PA-supportive parenting practices and SA ethnicity were associated with lower walking frequency at 24 and 36 months of age among children (p < 0.01). More frequent exposure to TV at mealtimes and SA ethnicity were associated with higher TV viewing time at 24 and 36 months of age among children (p < 0.01).ConclusionsThis study demonstrated that SAB parents, particularly those who are foreign-born, apply parenting practices for their young children that are less supportive of PA and more supportive of TV viewing, and their children have lower PA and higher TV viewing time, compared with their WB counterparts.

Project description:BackgroundPrevious studies have shown markedly lower birth weight among infants of South Asian origin compared with those of White European origin. Whether such differences mask greater adiposity in South Asian infants and whether they persist across generations in contemporary UK populations is unclear. Our aim was to compare birth weight, skinfold thickness and cord leptin between Pakistani and White British infants and to investigate the explanatory factors, including parental and grandparental birthplace.MethodsWe examined the differences in birth weight and skinfold thickness between 4649 Pakistani and 4055 White British infants born at term in the same UK maternity unit and compared cord leptin in a subgroup of 775 Pakistani and 612 White British infants.ResultsPakistani infants were lighter (adjusted mean difference -234 g 95% CI -258 to -210) and were smaller in both subscapular and triceps skinfold measurements. The differences for subscapular and triceps skinfold thickness (mean z-score difference -0.27 95% CI -0.34 to -0.20 and -0.23 95% CI -0.30 to -0.16, respectively) were smaller than the difference in birth weight (mean z-score difference -0.52 95% CI -0.58 to -0.47) and attenuated to the null with adjustment for birth weight (0.03 95% CI -0.03 to 0.09 and -0.01 95% CI -0.08 to 0.05, respectively). Cord leptin concentration (indicator of fat mass) was similar in Pakistani and White British infants without adjustment for birth weight, but with adjustment became 30% higher (95% CI 17% to 44%) among Pakistani infants compared with White British infants. The magnitudes of difference did not differ by generation.ConclusionsDespite being markedly lighter, Pakistani infants had similar skinfold thicknesses and greater total fat mass, as indicated by cord leptin, for a given birth weight than White British infants. Any efforts to reduce ethnic inequalities in birth weight need to consider differences in adiposity and the possibility that increasing birth weight in South Asian infants might inadvertently worsen health by increasing relative adiposity.

Project description:BackgroundFood insecurity has been associated with dietary intake and weight status in UK adults and children although results have been mixed and ethnicity has not been explored. We aimed to compare prevalence and trajectories of weight and dietary intakes among food secure and insecure White British and Pakistani-origin families.MethodsAt 12 months postpartum, mothers in the Born in Bradford cohort completed a questionnaire on food security status and a food frequency questionnaire (FFQ) assessing their child's intake in the previous month; at 18 months postpartum, mothers completed a short-form FFQ assessing dietary intake in the previous 12 months. Weights and heights of mothers and infants were assessed at 12-, 24-, and 36-months postpartum, with an additional measurement of children taken at 4-5 years. Associations between food security status and dietary intakes were assessed using Wilcoxon-Mann-Whitney for continuous variables and ?2 or Fisher's exact tests for categorical variables. Quantile and logistic regression were used to determine dietary intakes adjusting for mother's age. Linear mixed effects models were used to assess longitudinal changes in body mass index (BMI) in mothers and BMI z-scores in children.ResultsAt 12 months postpartum, White British mothers reported more food insecurity than Pakistani-origin mothers (11% vs 7%; p?<?0.01) and more food insecure mothers were overweight. Between 12 and 36 months postpartum, BMI increased more among food insecure Pakistani-origin mothers (??=?0.77 units, [95% Confidence Interval [CI]: 0.40, 1.10]) than food secure (??=?0.44 units, 95% CI: 0.33, 0.55). This was also found in Pakistani-origin children (BMI z-score: food insecure ??=?0.40 units, 95% CI: 0.22, 0.59; food secure ??=?0.25 units, 95% CI: 0.20, 0.29). No significant increases in BMI were observed for food secure or insecure White British mothers while BMI z-score increased by 0.17 (95% CI: 0.13, 0.21) for food secure White British children. Food insecure mothers and children had dietary intakes of poorer quality, with fewer vegetables and higher consumption of sugar-sweetened drinks.ConclusionsFood security status is associated with body weight and dietary intakes differentially by ethnicity. These are important considerations for developing targeted interventions.

Project description:Aims/hypothesisThere is evidence that, from birth, South Asians are fatter, for a given body mass, than Europeans. The role of developmental overnutrition related to maternal adiposity and circulating glucose in these ethnic differences is unclear. Our aim was to compare associations of maternal gestational adiposity and glucose with adiposity at age 4/5 years in white British and Pakistani children.MethodsBorn in Bradford is a prospective study of children born between 2007 and 2010 in Bradford, UK. Mothers completed an OGTT at 27-28 weeks of gestation. We examined associations between maternal gestational BMI, fasting glucose, post-load glucose and diabetes (GDM) and offspring height, weight, BMI and subscapular skinfold (SSF) and triceps skinfold (TSF) thickness at age 4/5 years, using data from 6060 mother-offspring pairs (2717 [44.8%] white British and 3343 [55.2%] Pakistani).ResultsPakistani mothers had lower BMI and higher fasting and post-load glucose and were twice as likely to have GDM (defined using modified WHO criteria) than white British women (15.8% vs 6.9%). Pakistani children were taller and had lower BMI than white British children; they had similar SSF and lower TSF. Maternal BMI was positively associated with the adiposity of offspring in both ethnic groups, with some evidence of stronger associations in Pakistani mother-offspring pairs. For example, the difference in adjusted mean BMI per 1 kg/m2 greater maternal BMI was 0.07 kg/m2 (95% CI 0.05, 0.08) and 0.10 kg/m2 (95% CI 0.09. 0.11) in white British and Pakistani children, respectively, with equivalent results for SSF being 0.07 mm (95% CI 0.05, 0.08) and 0.09 mm (95% CI 0.08. 0.11) (p for ethnic difference < 0.03 for both). There was no strong evidence of association of fasting and post-load glucose, or GDM, with outcomes in either group.Conclusions/interpretationAt age 4/5 years, Pakistani children are taller and lighter than white British children. While maternal BMI is positively associated with offspring adiposity, gestational glycaemia is not clearly related to offspring adiposity in either ethnic group.
