Responsive feeding serves as an important protective factor for infant growth and overall health development. This study based on self‐determination theory (SDT) aimed to assess the effects of a responsive breastfeeding (RBF) intervention programme on maternal breastfeeding and infant growth and development. A total of 110 mother–infant pairs were recruited and randomly divided into an intervention group (n = 55) and a control group (n = 55). The primary outcomes were breastfeeding motivation score, breastfeeding self‐efficacy (BSE) and exclusive breastfeeding rate; the secondary outcomes were infant physical development at 6 weeks and 3 months. A repeated measures ANOVA indicated that the intervention group had significantly higher Enjoyment scores compared to the control group at three time points: at discharge (MD: 5.28; 95% CI: 3.68 to 6.89; p < 0.001), 6 weeks post‐partum (MD: 5.06; 95% CI: 3.80 to 6.31; p < 0.001) and 3 months post‐partum (MD: 5.24; 95% CI: 4.12 to 6.35; p < 0.001). Similarly, the intervention group reported significantly higher connection and mother's self‐perception scores at discharge (MD: 4.31; 95% CI: 3.07 to 5.56; p < 0.001), 6 weeks post‐partum (MD: 4.69; 95% CI: 3.71 to 5.68; p < 0.001) and 3 months post‐partum (MD: 4.93; 95% CI: 4.14 to 5.72; p < 0.001), compared to the control group. In contrast, the pressure from significant others scores were higher in the control group relative to the intervention group at discharge (MD: −2.09; 95% CI: −2.88 to −1.31; p < 0.001), 6 weeks post‐partum (MD: −4.35; 95% CI: −5.20 to −3.49; p < 0.001) and 3 months (MD: −4.89; 95% CI: −5.70 to −4.08; p < 0.001). Finally, the intervention group also reported higher Instrumental Needs scores at all three time points: at discharge (MD: 1.96; 95% CI: 1.35 to 2.58; p < 0.001), 6 weeks post‐partum (MD: 3.58; 95% CI: 3.05 to 4.11; p < 0.001) and 3 months post‐partum (MD: 1.18; 95% CI: 0.68 to 1.69; p < 0.001). BSE scores were significantly higher in the intervention group compared to the control group at discharge (MD: 14.29; 95% CI: 10.38 to 18.21; p < 0.001), 6 weeks post‐partum (MD: 14.04; 95% CI: 11.05 to 17.02; p < 0.001) and 3 months post‐partum (MD: 6.80; 95% CI: 4.66 to 8.94; p < 0.001). The rates of exclusive breastfeeding were higher in the intervention group than in the control group at each stage of the intervention (p < 0.01). At 6 weeks post‐partum, the intervention group's infants showed slower weight (t = −0.90, p = 0.371) and length (t = −0.69, p = 0.495) growth compared to the control group, though not significantly. By 3 months post‐partum, there was a significant difference in both weight (t = −3.46, p = 0.001) and length (t = −2.95, p = 0.004) between the groups. The findings in this study suggest that the RBF intervention programme based on SDT may be effective in improving mothers' motivation to breastfeed, building breastfeeding self‐confidence and increasing the rate of exclusive breastfeeding. The effects of the intervention on infant physical development will need to be verified with longer follow‐up in future research. Key messages: This study validated the application of responsive breastfeeding (RBF) intervention during the exclusive breastfeeding phase of Chinese infants.The RBF intervention may help to increase mothers' level of autonomous motivation for breastfeeding, enhance breastfeeding self‐efficacy and increase exclusive breastfeedingrates. The intervention had no significant effect on the weight and length of 6 week old infants but significantly impacted 3monthold infants, with slower growth observed in the intervention group compared to the control group.Future intervention programmes shouldinclude extended follow‐up periods to investigate the long‐term effects of RBF on infant growth and development.

The southeastern region of Kenya is prone to aflatoxin outbreaks, yet maternal and infant aflatoxin intake levels remain unclear. We determined dietary aflatoxin exposure of 170 lactating mothers breastfeeding children aged 6 months and below in a descriptive cross‐sectional study involving aflatoxin analysis of maize‐based cooked food samples (n = 48). Their socioeconomic characteristics, food consumption patterns and postharvest handling of maize were determined. Aflatoxins were determined using high‐performance liquid chromatography and enzyme‐linked immunosorbent assay. Statistical analysis was conducted using Statistical Package Software for Social Sciences (SPSS version 27) and Palisade's @Risk software. About 46% of the mothers were from low‐income households, and 48.2% had not attained the basic level of education. A generally low dietary diversity was reported among 54.1% of lactating mothers. Food consumption pattern was skewed towards starchy staples. Approximately 50% never treated their maize, and at least 20% stored their maize in containers that promote aflatoxin contamination. Aflatoxin was detected in 85.4% of food samples. The mean of total aflatoxin was 97.8 μg/kg (standard deviation [SD], 57.7), while aflatoxin B1 was 9.0 μg/kg (SD, 7.7). The mean dietary intake of total aflatoxin and aflatoxin B1 was 7.6 μg/kg/b.w.t/day (SD, 7.5) and 0.6 (SD, 0.6), respectively. Dietary aflatoxin exposure of lactating mothers was high (margin of exposure < 10,000). Sociodemographic characteristics, food consumption patterns and postharvest handling of maize variably influenced dietary aflatoxin exposure of the mothers. The high prevalence and presence of aflatoxin in foods of lactating mothers are a public health concern and calls for the need to devise easy‐to‐use household food safety and monitoring measures in the study area. Key messages: A high prevalence of aflatoxin (84.4%) and high dietary aflatoxin exposure were reported among lactating mothers in the study.The mean concentration of 90% of maize‐based cooked food samples exceeded the 2 and 10 µg/kg set limits for aflatoxin B1 and total aflatoxin, respectively.Household size, education, socioeconomic status and limited food consumption patterns were potential determinants of dietary aflatoxin exposure in lactating mothers. Within dietary diversity, the type of food constituting a diverse diet played an important role.Postharvest handling of maize could be one of the factors contributing to dietary aflatoxin exposure in the study area.The reported results call for the need to devise easy‐to‐use household food safety and monitoring measures in the study area.

Weight‐for‐age (WFA) growth faltering often precedes severe acute malnutrition (SAM) in children, yet it is often missed during routine growth monitoring. Automated interpretation of WFA growth within electronic health records could expedite the identification of children at risk of SAM. This study aimed to develop an automated screening tool to predict SAM risk from WFA growth, and to determine its predictive ability compared with simple changes in weight or WFA z‐score. To develop the screening tool, South African child growth experts (n = 30) rated SAM risk on 100 WFA growth curves, which were then used to train an artificial neural network (ANN) to assess SAM risk from consecutive WFA z‐scores. The ANN was validated in 185 children under five (63 SAM cases; 122 controls) using diagnostic accuracy methodology. The ANN's performance was compared with that of changes in weight or WFA z‐score. Even though experts' SAM risk ratings of the WFA growth curves differed considerably, the ANN achieved a sensitivity of 73.0% (95% confidence interval [CI]: 60.3; 83.4), specificity of 86.1% (95% CI: 78.6; 91.7) and receiver‐operating characteristic curve area of 0.795 (95% CI: 0.732; 0.859) during validation with real cases, outperforming changes in weight or WFA z‐scores. The ANN, as an automated screening tool, could markedly improve the identification of children at risk of SAM using routinely collected WFA growth information. Key messages: Growth faltering preceding severe acute malnutrition (SAM) is poorly identified during routine growth monitoring, and opportunities for preventative interventions are missed.Consistently identifying growth faltering is challenging, even for experts in child growth. Digitized growth monitoring tools incorporating automated pattern recognition by an artificial neural network (ANN) can assist clinicians in identifying growth faltering.In this study, an ANN was trained to identify children at risk of SAM based on weight‐for‐age growth curves, with promising results. With further refinement, the ANN could greatly improve the identification of children with growth faltering and facilitate earlier interventions to prevent SAM. [ABSTRACT FROM AUTHOR]

Dietary intake during pregnancy may influence child neurodevelopment and cognitive function. This study aims to investigate the associations between dietary patterns obtained in pregnancy and intelligence quotients (IQ) among offspring at 8 years of age. Pregnant women enrolled in the Avon Longitudinal Study of Parents and Children completed a food frequency questionnaire at 32 weeks' gestation ( n = 12,195). Dietary patterns were obtained by cluster analysis. Three clusters best described women's diets during pregnancy: 'fruit and vegetables,' 'meat and potatoes,' and 'white bread and coffee.' The offspring's IQ at 8 years of age was assessed using the Wechsler Intelligence Scale for Children. Models, using variables correlated to IQ data, were performed to impute missing values. Linear regression models were employed to investigate associations between the maternal clusters and IQ in childhood. Children of women who were classified in the meat and potatoes cluster and white bread and coffee cluster during pregnancy had lower average verbal (β = −1.74; p < .001 and β = −3.05; p < .001), performance (β = −1.26; p = .011 and β = −1.75; p < .001), and full-scale IQ (β = −1.74; p < .001 and β = −2.79; p < .001) at 8 years of age when compared to children of mothers in the fruit and vegetables cluster in imputed models of IQ and all confounders, after adjustment for a wide range of known confounders including maternal education. The pregnant women who were classified in the fruit and vegetables cluster had offspring with higher average IQ compared with offspring of mothers in the meat and potatoes cluster and white bread and coffee cluster.

Prenatal methyl donor deficiency leads to homocysteine accumulation in the brain and impaired neurodevelopment in rats. We investigated the effect of moderately elevated preconception fasting total plasma homocysteine (tHcy) on child neurodevelopment in a prospective study of 67 and 76 mother-child pairs at 4 months and 6 years of age, respectively. Fasting blood samples at 2-10 weeks preconception, from the cord (nonfasting) and the mother and child 6 years after birth, were collected. Psychomotor and mental development were assessed at 4 months using the Bayley Scale of Infant Development (BSID) and cognitive development at 6 years using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Highest tertile preconception tHcy (≥9.04 µmol/L) was categorized as moderately elevated and low-mid tertile tHcy as normal. Children, born to mothers with moderately elevated compared to normal preconception tHcy, scored lower [mean (95% CI)] in the BSID psychomotor [115 (105, 124) vs. 126 (121, 130), p = 0.03] and mental [101 (93, 109) vs. 113 (107, 119), p = 0.03] development tests. Multiple logistic regression analysis showed that moderately elevated compared to normal preconception tHcy was associated with greater probability, OR (95%CI), of scoring in the lowest tertile for BSID psychomotor development (≤120): 4.0 (1.1, 14.3) and lowest tertiles for WPPSI full (≤111), verbal (≤104) and performance (≤111), intellectual quotient: 6.0 (1.5, 23.7), 3.5 (1.1, 11.2) and 4.1 (1.1, 15.7), respectively. We conclude that moderately elevated preconception tHcy is inversely associated with psychomotor and cognitive development scores in infants and children. [ABSTRACT FROM AUTHOR]

Community‐based management of acute malnutrition (CMAM) is effective in treating acute malnutrition. However, post‐discharge follow‐up often lacks. We aimed at assessing the relapse rate and the associated factors in a CMAM programme in Burkina Faso. Discharged children from the community nutrition centre were requested to return at least every 3 months for follow‐up. The data of recovered children (weight‐for‐height z‐score ≥−2) who were discharged between July 2010 and June 2011 were collected in 45 villages, randomly selected out of 210 in January 2012. Sociodemographic data, economic variables, information on household food availability and the child's food consumption in the last 24 h were collected from the parents. A multivariate Cox proportional hazards regression was used to identify the factors associated to relapse. Of the 637 children, 14 (2.2%) died and 218 (34.2%) were lost to follow‐up. The relapse rate [95% confidence interval] among the children who returned for follow‐up was 15.4 [11.8–19.0] per 100 children‐years. The associated factors to relapses in multivariate Cox regression model were mid‐upper arm circumference (MUAC) at discharge below 125 mm, no oil/fat consumption during the last 24 h and incomplete vaccination. To limit relapses, CMAM programmes should avoid premature discharge before a MUAC of at least 125 mm. Nutrition education should emphasize fat/oil as inexpensive energy source for children. Promoting immunization is essential to promote child growth. Periodic monitoring of discharged children should be organized to detect earlier those who are at risk of relapse. The relapse rate should be a CMAM effectiveness indicator. [ABSTRACT FROM AUTHOR]

Objectives Emergency departments ( EDs) commonly analyze cases of patients returning within 72 hours of initial ED discharge as potential opportunities for quality improvement. In this study, we tested the use of a health information exchange ( HIE) to improve identification of 72-hour return visits compared to individual hospitals' site-specific data. Methods We collected deidentified patient data over a 5-year study period from Healthix, an HIE in the New York metropolitan area. We measured site-specific 72-hour ED returns and compared these data to those obtained from a regional 31-site HIE (Healthix) and to those from a smaller, antecedent 11-site HIE. Although only ED visits were counted as index visits, either ED or inpatient revisits within 72 hours of the index visit were considered as early returns. Results A total of 12,669,657 patient encounters were analyzed across the 31 HIE EDs, including 6,352,829 encounters from the antecedent 11-site HIE. Site-specific 72-hour return visit rates ranged from 1.1% to 15.2% (median = 5.8%) among the individual 31 sites. When the larger HIE was used to identify return visits to any site, individual EDs had a 72-hour return frequency of 1.8% to 15.5% (median = 6.8%). HIE increased the identification ability of 72-hour ED return analyses by a mean of 11.16% (95% confidence interval = 11.10% to 11.22%) compared with site-specific (no HIE) analyses. Conclusion This analysis demonstrates incremental improvements in our ability to identify early ED returns using increasing levels of HIE data aggregation. Although intuitive, this has not been previously described using HIE. ED quality measurement and patient safety efforts may be aided by using HIE in 72-hour return analyses. [ABSTRACT FROM AUTHOR]

Objective: To investigate whether the introduction of non‐invasive pre‐natal testing for Down's syndrome (DS) has the potential to undermine informed choice. Participants: Three hundred and ninety‐three health professionals; 523 pregnant women. Methods: A cross‐sectional questionnaire study across nine maternity units and three conferences in the UK designed to assess opinions regarding test delivery and how information should be communicated to women when offered Down's syndrome screening (DSS) or diagnosis using invasive (IDT) or non‐invasive testing (NIPT). Results: Both pregnant women and health professionals in the NIPT and DSS groups were less likely than the IDT group to consider that testing should take place at a return visit or that obtaining written consent was necessary, and more likely to think testing should be carried out routinely. Compared to health professionals, pregnant women expressed a stronger preference for testing to occur on the same day as pre‐test counselling (P = 0.000) and for invasive testing to be offered routinely (P = 0.000). They were also more likely to indicate written consent as necessary for DSS (P = 0.000) and NIPT (P < 0.05). Conclusions: Health professionals and pregnant women view the consenting process differently across antenatal test types. These differences suggest that informed choice may be undermined with the introduction of NIPT for DS into clinical practice. To maintain high standards of care, effective professional training programmes and practice guidelines are needed which prioritize informed consent and take into account the views and needs of service users.

Background: Knowledge of molecular biology and genomics continues to expand rapidly, promising numerous opportunities for improving health. However, a key aspect of the success of genomic medicine is related to public understanding and acceptance. Design: Using community consultations and an online survey, we explored public attitudes and expectations about genomics research. Results: Thirty‐three members of the general public in Newfoundland, Canada, took part in the community sessions, while 1024 Atlantic Canadians completed the online survey. Overall, many participants noted they lacked knowledge about genetics and associated research and took the opportunity to ask numerous questions throughout sessions. Participants were largely hopeful about genomics research in its capacity to improve health, not only for current residents, but also for future generations. However, they did not accept such research uncritically, and a variety of complex issues and questions arose during the community consultations and were reflected in survey responses. Discussion: With the proliferation of biobanks and the rapid pace of discoveries in genomics research, public support will be crucial to realize health improvements. If researchers can engage the public in regular, transparent dialogue, this two‐way communication could allow greater understanding of the research process and the design of efficient and effective genetic health services, informed by the public that will use them.

This study is the first that longitudinally examined change in occupational self-efficacy ( OSE) through individual and shared participation in occupational stress management courses ( SMC). Applying the framework of social cognitive theory ( Bandura, 1986, Social foundations of thought and action: A social cognitive theory. Englewood Cliffs, NJ: Prentice- Hall), we assumed that participation in SMC facilitates OSE perceptions. We further assumed that the psychosocial environment promotes change in OSE through high shared participation (reach) in SMC within work groups. Comparing participants and non-participants, we conducted growth analyses with three waves of data nested in n = 545 employees further nested in 97 work groups. The results showed that individual participation in SMC alone was insufficient to enhance OSE, a combination of individual and high shared participation being needed to significantly enhance OSE perceptions over a period of 2 years. The results are discussed with reference to specificity issues and the role of the psychosocial environment by applying social identity theory and the notion of shared mental models. We conclude by recommending SMC as a feasible intervention to enhance OSE in heterogeneous occupational contexts - if a majority of work group members can be involved. Practitioner points The study recommends stress management courses for enhancing occupational self-efficacy as a short and relatively low-cost intervention that is feasible to implement in various occupational and organizational contexts., The key point here is that a majority of work group members are encouraged to engage in courses to obtain the beneficial effects on change in occupational self-efficacy.

Objectives The objective was to characterize the variations in practice in the diagnosis and management of children admitted to hospitals from Canadian pediatric emergency departments ( EDs) with suspected appendicitis, specifically the timing of surgical intervention, ED investigations, and management strategies. Methods Twelve sites participated in this retrospective health record review. Children aged 3 to 17 years admitted to the hospital with suspected appendicitis were eligible. Site-specific demographics, investigations, and interventions performed were recorded and compared. Factors associated with after-hours surgery were determined using generalized estimating equations logistic regression. Results Of the 619 children meeting eligibility criteria, surgical intervention was performed in 547 (88%). After-hours surgery occurred in 76 of the 547 children, with significant variation across sites (13.9%, 95% confidence interval = 7.1% to 21.6%, p < 0.001). The overall perforation rate was 17.4% (95 of 547), and the negative appendectomy rate was 6.8% (37 of 547), varying across sites (p = 0.004 and p = 0.036, respectively). Use of inflammatory markers (p < 0.001), blood cultures (p < 0.001), ultrasound (p = 0.001), and computed tomography (p = 0.001) also varied by site. ED administration of narcotic analgesia and antibiotics varied across sites (p < 0.001 and p = 0.001, respectively), as did the type of surgical approach (p < 0.001). After-hours triage had a significant inverse association with after-hours surgery (p = 0.014). Conclusions Across Canadian pediatric EDs, there exists significant variation in the diagnosis and management of children with suspected appendicitis. These results indicate that the best diagnostic and management strategies remain unclear and support the need for future prospective, multicenter studies to identify strategies associated with optimal patient outcomes.

Growth patterns in early life are associated with later health. The effect of nutrition during in utero development on later body composition is unclear. We evaluated whether prenatal early invitation to food and/or multiple micronutrient supplementation ( MMS) in pregnancy has an effect on offspring body composition at 54 months of age. In Maternal and Infant Nutrition Interventions in Matlab trial ( ISRCTN16581394) in Bangladesh, 4436 pregnant women were randomised into six equally sized groups: double-masked supplementation with capsules of either 30 mg Fe and 400 μg folic acid, or 60 mg Fe and 400 μg folic acid, or MMS (15 micronutrients), was combined with a randomised early invitation (around 9 weeks) or a usual invitation (around 20 weeks) to start food supplementation (608 kcal 6 days per week). At 54 months, the body composition of the offspring was assessed by leg-to-leg bioelectrical impedance analysis. Of the 3267 live singletons with birth anthropometry, 2290 children were measured at 54 months, representing 70% of the live births. There was no interaction between the food and micronutrient supplementation on body composition outcomes. There were no significant differences in a range of anthropometric and body composition measurements, including weight, height, mid-upper arm circumference, head circumference, skinfold thickness, and fat mass and fat-free mass between the different prenatal food and micronutrient groups using an intention-to-treat analysis. This analysis shows that early invitation to food supplementation and MMS provided to rural Bangladeshi women during pregnancy did not affect offspring body composition at 54 months of age.

Objectives Chest pain is a common complaint to emergency departments ( EDs) and clinical risk factors are used to predict which patients are at risk for worse outcomes and mortality. The goal was to assess the novel biomarker midregional proadrenomedullin ( MR-pro ADM) in prediction of mortality and major adverse cardiac events ( MACE). Methods This was a subanalysis of the CHOPIN study, a 16-center prospective trial that enrolled 2,071 patients presenting with chest pain within 6 hours of onset. The primary endpoint was 6-month all-cause mortality and the secondary endpoint was 30-day and 6-month MACE: ED visits or hospitalization for acute myocardial infarction, unstable angina, reinfarction, revascularization, and heart failure. Results MR-pro ADM performed similarly to troponin ( cTnI; c-statistic = 0.845 and 0.794, respectively) for mortality prediction in all subjects and had similar results in those with noncardiac diagnoses. MR-pro ADM concentrations were stratified by decile, and the cohort in the top decile had a 9.8% 6-month mortality risk versus 0.9% risk for those in the bottom nine deciles (p < 0.0001). MR-pro ADM, history of coronary artery disease ( CAD), and hypertension were predictors of short-term MACE, while history of CAD, hypertension, cTnI, and MR-pro ADM were predictors of long-term MACE. Conclusions In patients with chest pain, MR-pro ADM predicts mortality and MACE in all-comers with chest pain and has similar prediction in those with a noncardiac diagnosis. This exploratory analysis is primarily hypotheses-generating and future prospective studies to identify its utility in risk stratification should be considered. [ABSTRACT FROM AUTHOR]

Background Patient preference for the choice of treatment modality for prostate cancer has increasingly gained attention. Objective To assess the impact of client-oriented decision on long-term mortality, disease progression and biochemical failure compared with standard treatment protocol ( TP). Methods With data from a Finnish multicentre, randomized controlled trial with two arms [104 in the enhanced patient participation ( EPP) arm and 106 in the TP arm], disease-specific and disease-free survival, biochemical failure with elevated prostate-specific antigen ( PSA) level and disease progression were compared between the two arms using Wilcoxon test and also Cox proportional hazards regression model. Results Patients in the EPP arm had a higher risk of death by 37% [ HR, 1.37 (0.87-2.17)] compared with those in the TP arm. Patients in the EPP arm were at increased risk of having biochemical failure by 14% [ HR, 1.14 (0.72-1.79)] and for having disease progression by 2% [ HR, 1.02 (0.61-1.70)] compared with those in the TP arm. All the differences were non-significant. Conclusions Patients actively involved in the choice of treatment had higher risk of prostate cancer death but only slightly increased risk of biochemical failure and clinical disease progression. These findings would provide a good reference when patient autonomy for the choice of treatment modality is addressed. [ABSTRACT FROM AUTHOR]

Background There are doubts on whether patients feel that they have sufficient information for actively participating in clinical decisions. Objective To describe the type of information that patients receive. To determine whether patients consider this information sufficient, and whether it contributes or not to improve clinical safety. To identify the barriers for patient participation in clinical decision making. Study Design Cross-sectional study with 764 patients and 327 physicians. Study Setting and participants Fourteen health centres belonging to three primary care districts and three hospitals in Spain. Principal Findings Just 35.1% (268) (95% CI 32.2, 39.1%) of patients preferred to have the last word in clinical decisions. Age (39 vs. 62%, P < 0.001) and severity of illness (38 vs. 46%, P = 0.002) increased the tendency to take a passive role. In 85.1% (650) (95% CI 83.3, 88.3%) of the cases, patients reported having received sufficient information. Lack of consultation time (29.6%, 95% CI 25.8, 32.5%) and patients' use of Internet or other sources (19.2%, 95% CI 16.4, 22.2%) were identified as new obstacles to doctor-patient communication by the patients. Only 19.6% (64) (95% CI 15.4, 24.2%) of doctors considered that they could intervene to involve patients in the decisions. Discussions and Conclusions The majority of patients prefer the decisions to be made by their doctor, especially those with more severe illnesses, and older patients. Patients are not normally informed about medication interactions, precautions and foreseeable complications. The information provided by general practitioners does not seem to contribute enough to the patient involvement in clinical safety. [ABSTRACT FROM AUTHOR]

A case-control study was conducted to determine the association between maternal height and infant length-for-age, and to evaluate how this association is modified by either maternal or infant nutritional status. We hypothesised that maternal excess caloric intake [measured as body mass index (BMI)] would increase the association, while infant nutrition (measured in main meals consumed in addition to breastfeeding) will diminish the effect. Mother and infant pairs in Chimaltenango, Guatemala, were measured for anthropometric values and nutritional status, and mothers were interviewed to elicit nutritional and socio-economic information. Infant length was converted into z-scores based on the World Health Organization's (WHO) standards. Odds ratios (ORs), associated 95% confidence intervals (CIs) and the relative excess risk due to interaction (RERI) were calculated. Cases were infants below 2 z-scores of the WHO's length-for-age, while controls were infants within the −2 to 2 z-score range. Cases ( n = 84) had an increased odds (OR: 3.00, 95% CI: 1.57-5.74) of being born to a stunted mother (below 145 cm) when compared with controls ( n = 85). When adjusted for potential confounders, the OR decreased to 2.55 (95% CI: 1.30-5.02). Negative RERI values were produced for the joint exposure of maternal BMI ≥ 25 and maternal stuntedness (RERI: −0.96), as well as for the joint exposure of maternal stuntedness and infant nutrition (RERI: −2.27). Our results confirm that maternal stuntedness is a significant contributor to infant stuntedness; however, this association is modified negligibly by maternal nutritional status and significantly by infant nutritional status, each in a protective manner.

Vitamin D deficiency may be a risk factor for negative outcome in pregnancy, such as pre-term labour, low birthweight, intrauterine growth retardation and gestational diabetes. This study aimed to evaluate the relationship between vitamin D and pre-eclampsia. This was a case-control study of 59 pre-eclamptic women and 59 healthy pregnant women selected in two hospitals in Ahvaz, Iran. Women with term singleton pregnancy, nulliparous and of reproductive age were selected. Venous blood samples (2 mL) were taken and the level of 25-dihydroxy vitamin D (25- OH- D) was measured. If the levels of 25- OH- D were less than 10 ng mL−1, between 10 ng mL−1 and 29 ng mL−1 and more than 30 ng mL−1, they were considered as indicating deficient, insufficient and normal 25- OH- D concentrations, respectively. The independent t-test, Mann- Whitney U-test, chi-square and logistic regression were used for analysing the data. Vitamin D deficiency was significantly higher in the pre-eclampsia group [odds ratio ( OR) = 24.04, confidence interval ( CI) = 2.10-274.8, P = 0.01]. Older women (30-35 years) were more likely to develop pre-eclampsia compared with the control group ( OR = 10.36, CI = 2.18-49.09, P = 0.003). The results showed that women with body mass index ( BMI) <20 were more likely to develop pre-eclampsia. The ages between 20 years and 30 years and normal BMI were not the risk factors for pre-eclampsia. Vitamin D deficiency has a statistically significant relationship with pre-eclampsia. It seems that the serum vitamin D levels are low in Iranian women because of their particular lifestyle and they may need more than 400 IU day−1 vitamin D supplement during pregnancy.

The influence of childhood nutrition on the development of constipation beyond the period of weaning and breastfeeding is relatively understudied. In addition, eating patterns in childhood can be highly correlated with overweight and sedentary behaviour, which may also have an influence on constipation. The aim of this study was to assess whether common dietary patterns, sedentary behaviour and childhood overweight are associated with constipation in childhood. The study was embedded in a population-based prospective birth cohort. Information on dietary intake was obtained by a food frequency questionnaire at the child's age of 14 months ( n = 2420). The adherence scores on a 'Health conscious' and 'Western-like' diet were extracted from principal component analysis. At the age of 24, 36 and 48 months, information on constipation and sedentary behaviour, and weight and height was obtained by parental-derived questionnaires and from the child health centres, respectively. Adherence to a 'Western-like' dietary pattern was associated with a higher prevalence of constipation up to 48 months [adjusted odds ratio (aOR); 95% confidence interval (CI): 1.39; 1.02-1.87], which was not mediated by overweight or sedentary behaviour. Adherence to a 'Health Conscious' dietary pattern was only associated at short term, with a lower prevalence of constipation at 24 months (aOR; 95%CI: 0.65; 0.44-0.96). No association was found between overweight, sedentary behaviour and constipation. Our results suggest that specific dietary patterns in early childhood could be associated with higher or lower risks for constipation, but these effects are time-dependent. Overweight and sedentary behaviour seem to not have a major role on constipation in childhood. [ABSTRACT FROM AUTHOR]

Inappropriate complementary feeding practices have led to, in part, significant disparities in growth and nutritional status between rural and urban children in China. A cluster-randomised, controlled trial was implemented in Laishui, China to assess the effectiveness of an educational intervention on caregivers' feeding practices and children's growth. Eight townships were randomly assigned to the intervention or control. Five hundred ninety-nine healthy infants were enrolled at 2-4 months old, and were followed up at ages 6, 9, 12, 15 and 18 months. The intervention group received information on enhanced home-prepared recipes and food preparation and hygiene through group training, counselling and home visit. Key outcomes were children's physical growth, caregivers' knowledge and behaviours on complementary feeding, and the infant and child feeding index ( ICFI). Analysis was by intention to treat. The intervention group achieved better knowledge and practices related to complementary feeding, and significantly higher ICFI scores at each follow-up point. Children in the intervention group achieved higher z-scores for weight-for-age ( WAZ) and weight-for-height ( WHZ) than the control (0.18 vs. 0.01 and 0.49 vs. 0.19, respectively) at 18 months old, and were less likely to have stunted growth (odds ratio = 0.71, 95% confidence interval: 0.53-0.94). Mixed model showed that the intervention group achieved significantly better linear growth over time, including WAZ ( P = 0.016), WHZ ( P = 0.030) and HAZ ( P = 0.078). These results indicated that an educational intervention delivered through local health services can enhance caregivers' knowledge and practices of complementary feeding and ultimately improve children's growth.

ACADEMIC EMERGENCY MEDICINE 2011; 18:1177-1185 © 2011 by the Society for Academic Emergency Medicine Abstract Objectives: The objective of this study was to assess the association between the performance of practicing paramedics on a validated cognitive exam and their field performance, assessed on a simulated emergency medical services (EMS) response. Methods: This was an observational study of paramedics from a single-tiered, urban, advanced life support EMS agency. A high-fidelity simulated response to a medical emergency on environmentally realistic sound stages, and the cognitive portion of the national paramedic certification exam, were each assessed as pass or fail. Participants were randomly assigned to one of six simulations designed by the agency's educational staff, medical director, and representatives from the National Registry of EMTs to be equivalently difficult. Simulations were pilot tested to assess content and face validity. Each participant was classified as failing a simulation scenario if his or her score was one standard deviation (SD) below the population mean. Results: There were 107 paramedics who participated in the study. Participants reported a median of 7.7 years of service (interquartile range [IQR] = 4.1 to 12.8 years). Simulation scores were normally distributed. Ninety-two (86.0%) participants received a passing score for the simulation and 77 (72.0%) passed the cognitive exam. There were 70 (65.4%) individuals who passed both the simulation and the cognitive exam, eight (7.5%) who failed both the simulation and the cognitive exam, 22 (20.6%) who passed the simulation but failed the cognitive exam, and seven (6.5%) who failed the simulation but passed the cognitive exam. There was a significant association between passing the cognitive exam and passing the simulation (chi-square p-value = 0.02). Conclusions: This study simultaneously assessed cognitive knowledge and simulated field performance. Utilization of these measurement techniques allowed for the assessment and comparison of field performance and cognitive knowledge. Results demonstrated an association between a practicing paramedic's performance on a cognitive examination and field performance, assessed by a simulated EMS response. [ABSTRACT FROM AUTHOR]

ACADEMIC EMERGENCY MEDICINE 2011; 18:934-940 © 2011 by the Society for Academic Emergency Medicine Abstract Objectives: The objective was to evaluate the effect of arrival to the emergency department (ED) by emergency medical services (EMS) on time to initiation of antibiotics, time to initiation of intravenous fluids (IVF), and in-hospital mortality in patients with severe sepsis and septic shock. Methods: The authors performed an evaluation of prospectively collected registry data of patients with a diagnosis of severe sepsis or septic shock who presented to an urban academic ED during a 2-year period from January 1, 2005, to December 31, 2006. Descriptive and multivariate analytic methods were used to analyze the data. Using unadjusted and adjusted models, out-of-hospital patients who presented to the ED by ambulance (EMS) were compared to control patients who arrived by alternative means (non-EMS). Primary outcomes measured were ED time to initiation of antibiotics, ED time to initiation of IVF, and in-hospital mortality. Results: A total of 963 severe sepsis patients were enrolled in the registry. Median time to antibiotics was 116 minutes for EMS (interquartile range [IQR] = 66 to 199) vs. 152 minutes for non-EMS (IQR = 92 to 252, p ≤ 0.001). Median time to initiation of IVF was 34 minutes for EMS (IQR = 10 to 88) and 68 minutes for non-EMS (IQR = 25 to 121, p ≤ 0.001). After adjustment for the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, age, and initial serum lactate level, no significant differences in hospital mortality were seen (adjusted relative risk [aRR] for EMS vs. non EMS = 1.24, 95% confidence interval [CI] = 0.92 to 1.66, p = 0.16). The Cox proportional hazard ratio (HR) comparing EMS to non-EMS care after similar adjustment was HR = 1.27 for IVF (95% CI = 1.10 to 1.47, p = 0.004) and HR = 1.25 for antibiotics (95% CI = 1.08 to 1.44, p = 0.003). Conclusions: Out-of-hospital care was associated with improved in-hospital processes for the care of critically ill patients. Despite shortened ED treatment times for septic patients who arrive by EMS, a mortality benefit could not be demonstrated. [ABSTRACT FROM AUTHOR]

Background: Cognitive dysfunction, including dementia and delirium, is prevalent in geriatric emergency department (ED) patients, but often remains undetected. One barrier to reliable identification of acutely or chronically impaired cognitive function is the lack of an acceptable screening tool. While multiple brief screening instruments have been derived, ED validation trials have not previously demonstrated tools that are appropriately sensitive for clinical use. Objectives: The primary objective was to evaluate and compare the Ottawa 3DY (O3DY), Brief Alzheimer's Screen (BAS), Short Blessed Test (SBT), and caregiver-completed AD8 (cAD8) diagnostic test performance for cognitive dysfunction in geriatric ED patients using the Mini Mental Status Exam (MMSE) as the criterion standard. A secondary objective was to assess the diagnostic accuracy for the cAD8 (which is an informant-based instrument) when used in combination with the other performance-based screening tools. Methods: In an observational cross-sectional cohort study at one urban academic university-affiliated medical center, trained research assistants (RAs) collected patients' responses on the Confusion Assessment Method for the Intensive Care Unit, BAS, and SBT. When available, reliable caregivers completed the cAD8. The MMSE was then obtained. The O3DY was reconstructed from elements of the MMSE and the BAS. Consenting subjects were non-critically ill, English-speaking adults over age 65 years, who had not received potentially sedating medications prior to or during cognitive testing. Using an MMSE score of ≤23 as the criterion standard for cognitive dysfunction, the sensitivity, specificity, likelihood ratios, and receiver operating characteristic (ROC) area under the curve (AUC) were computed. Venn diagrams were constructed to quantitatively compare the degree of overlap among positive test results between the performance-based instruments. Results: The prevalence of cognitive dysfunction for the 163 patients enrolled with complete data collection was 37%, including 5.5% with delirium. Dementia was self-reported in 3%. Caregivers were available to complete the cAD8 for 56% of patients. The SBT, BAS, and O3DY each demonstrated 95% sensitivity, compared with 83% sensitivity for the cAD8. The SBT had a superior specificity of 65%. No combination of instruments with the cAD8 significantly improved diagnostic accuracy. The SBT provided the optimal overlap with the MMSE.

Objectives: The rate of recombinant tissue plasminogen activator (rtPA) use for stroke is low among the Chinese-Taiwanese. The study objective was to determine if less restrictive exclusion criteria for rtPA would increase eligibility and the rate of treatment. Methods: This retrospective before-and-after study was conducted from 2006 to 2009. The authors compared stroke patients treated under the old rtPA exclusion criteria (January 2006 to December 2008) with those treated with less restrictive rtPA exclusion criteria (January to December 2009). Rates of eligibility and treatment and reasons for exclusion from rtPA between the two phases were assessed. Results: Of 461 eligible patients during the study period, 333 were evaluated by the old criteria and 128 were evaluated by the less restrictive criteria. Minor or improving stroke was the primary exclusion reason in both groups (194/333, 58% vs. 70/128, 55%). Eligibility for rtPA was increased in the less restrictive criteria (35/127, 27%, 95% confidence interval [CI] = 20% to 36%) compared to the old criteria (40/333, 12%, 95% CI = 8.7% to 16%; p = 0.0001). Fewer patients were excluded due to old age in the less restrictive criteria (0/128, 0%) compared to the old criteria (37/333, 11%; p = 0.0001). The rate of consent refusal increased in the less restrictive criteria (27/128, 21%, 95% CI = 14% to 29%) compared to the old criteria (23/333, 6.9%, 95% CI = 4.4% to 10%; p < 0.0001). Rate of rtPA treatment was unchanged between the less restrictive criteria (8/128, 6.3%, 95% CI = 2.7% to 12%) and the old criteria (17/333, 5.1%, 95% CI = 3% to 8%; p = 0.63). Conclusions: Increasing eligibility for rtPA does not increase the rate of treatment, possibly due to the high symptomatic intracerebral hemorrhage rate among Chinese-Taiwanese, which is a major concern among emergency physicians (EPs), neurologists, and patients. Dealing with perceived safety issues of rtPA is crucial before the rate of treatment can be increased. [ABSTRACT FROM AUTHOR]

Decision aids help patients make informed treatment decisions. Values clarification (VC) techniques are part of decision aids that help patients assimilate the information with their personal values. There is little evidence that these techniques contribute to enhanced decision making over and above the provision of good quality information. To assess whether VC techniques are active ingredients in enhancing informed decision making and explain how and why they work. Participants were randomly assigned to one of three groups: (i) information only, (ii) information plus implicit task, (iii) information plus explicit task. Thirty healthy women from a UK University participated by making a hypothetical choice between taking part in a clinical trial and having the standard treatment for breast cancer. Verbal protocols were elicited by think-aloud method and content analysed to assess informed decision making; a questionnaire was completed after the decision assessing decision preference, perceptions of decisional conflict and ambivalence. Data were analysed using multivariate statistics. No participants changed their decision preference as a result of the VC techniques. Women in the explicit VC group evaluated more information in accord with personal values, expressed lower ambivalence, decisional uncertainty and greater clarity of personal values than those in the implicit VC and control groups. Feelings of ambivalence about both options were related to decisional conflict. Explicit VC techniques are likely to be active ingredients in decision aids. They work by enabling people to deliberate about the decision information in accord with their personal values, which is associated with a better decision experience. [ABSTRACT FROM AUTHOR]

Methamphetamine is a drug of abuse that has been manufactured locally by chemical conversion from the decongestant pseudoephedrine. In July 2006, an Oregon state law was enacted to establish pseudoephedrine as a schedule III drug and make it available by prescription only. This study sought to determine if this legislation altered the number of emergency department (ED) visits that are related to methamphetamine use. This was a retrospective analysis of a database created during a prospective study aimed at determining the effect of methamphetamine on ED visits. That prospective study was 1 year in duration and required ED clinicians to determine whether a patient's visit was related to methamphetamine and if the patient had confirmed use of methamphetamine. The clinicians received initial and continued education and training on methamphetamine during the study period. The questions were asked at every ED visit during the study period and were electronically linked to the patient's disposition and could not be circumvented. The study period was divided into prelegislation (February 5, 2006, to June 30, 2006) and postlegislation periods (July 1, 2006, to February 5, 2007). Over the 1-year study period, 37,625 patients were enrolled, 1.90% ( n = 714) of patients had methamphetamine-related ED visits (MREDVs), and 1.65% ( n = 620) had confirmed methamphetamine use. Patients with MREDVs were more likely than patients with non-MREDVs to be white and uninsured. The number and proportion of weekly MREDVs significantly decreased from the prelegislation period to the postlegislation period (mean number of weekly visits, 18.0 vs. 11.3, p = 0.001; mean proportion of weekly visits, 2.3% vs. 1.6%, p = 0.003). The number and proportion of weekly confirmed users of methamphetamine also significantly decreased during the study period (mean number of weekly users, 14.6 vs. 10.3, p = 0.004; mean proportion of weekly users, 1.9% vs. 1.4%, p = 0.017). There were no significant differences in the diagnoses of MREDVS between the pre- and postlegislation periods. This study found an association between the enactment of legislation that limits pseudoephedrine availability and a decrease in MREDVs and confirmed users of methamphetamine in the study ED.

We assessed eight World Health Organization (WHO) core child feeding indicators for their association with stunting and underweight in Cambodia in 2000 and 2005. We compared the feeding data from the Cambodian Demographic and Health Surveys for 2000 with 2005 for 0–24 months children using the WHO feeding indicators, with stunting and underweight as outcomes. Prevalence of stunting and underweight was significantly less in 2005 than in 2000 among children aged 0–5 and 6–11 months, but stunting among children 18–23 months remained >50%. Prevalence of compliance with seven of the eight core healthy feeding indicators was higher in 2005. Exclusive breastfeeding among 0–5 months infants increased more than fivefold; among 6–11 and 12–17 months children, prevalence of feeding diversity and meeting a minimally acceptable diet, while improved, remained ≈25%. Modelling showed compliance with breastfeeding indicators was associated with reduced risk of underweight in 0–5 months infants, no association between compliance with feeding indicators and growth outcomes in other ages, and a significant association of higher relative wealth with growth outcomes overall. Between 2000 and 2005, Cambodia stabilized and focused resources on infant feeding. Prevalence of meeting the WHO feeding indicators improved, but modelling indicated that, in general, relative wealth, not feeding practices, was associated with improved growth outcomes. Yet, over 50% of children 18–23 months were stunted in 2005. Similar to the success with breastfeeding, focus on complementary feeding of 6–23 months children may reduce the risk of stunting in Cambodia. [ABSTRACT FROM AUTHOR]

ACADEMIC EMERGENCY MEDICINE 2010; 17:940–950 © 2010 by the Society for Academic Emergency Medicine Objectives: The objectives of this study were to determine concordance of emergency department (ED) management of acute myocardial infarction (AMI) with guideline recommendations and to identify ED and patient characteristics predictive of higher guideline concordance. Methods: The authors conducted a chart review study of ED AMI care as part of the National Emergency Department Safety Study (NEDSS). Using a primary hospital discharge diagnosis of AMI (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM], codes 410.XX), a random sample of ED visits for AMI in 58 urban EDs across 20 U.S. states between 2003 and 2006 were identified. Concordance with American College of Cardiology/American Heart Association (ACC/AHA) guideline recommendations was evaluated using five individual quality measures and a composite concordance score. Concordance scores were calculated as the percentage of eligible patients who received guidelines-recommended care. These percentage scores were rescaled from 0 to 100, with 100 indicating perfect concordance. Results: The cohort consisted of 3,819 subjects; their median age was 65 years, and 62% were men. The mean (± standard deviation [SD]) ED composite concordance score was 61 ± 8), with a broad range of values (42 to 84). Except for aspirin use (mean concordance, 82), ED concordance scores were low (beta-blocker use, 56; timely electrocardiogram [ECG], 41; timely fibrinolytic therapy, 26; timely ED disposition for primary percutaneous coronary intervention [PCI] candidates, 43). In multivariable analyses, older age (beta-coefficient per 10-year increase, −1.5; 95% confidence interval [CI] = −2.4 to −0.5) and southern EDs (beta-coefficient, −5.2; 95% CI = −9.6 to −0.9) were associated with lower guideline concordance, whereas ST-segment elevation on initial ED ECG was associated with higher guideline concordance (beta-coefficient, 3.6; 95% CI = 1.5 to 5.7). Conclusions: Overall ED concordance with guideline-recommended processes of care was low to moderate. Emergency physicians should continue to work with other stakeholders in AMI care, such as emergency medical services (EMS) and cardiologists, to develop strategies to improve care processes.

Introduction Shared decision making (SDM) is now considered a desirable goal in health care, yet little is known about current practice in cancer care, and its impact on patient outcomes. This study aimed to develop an oncology-specific coding system for SDM, explore variations in SDM according to patient and disease characteristics, determine the relationship between SDM and patient satisfaction with the consultation, and explore the impact of SDM on patient anxiety. Methods Sixty-three medical and radiation oncology consultations with patients with primary cancer involving consideration of adjuvant therapy after surgery were audio-taped, transcribed and coded. Intra and inter-rater reliability of the coding system was 95 and 90% respectively. Patients completed questionnaires before and after the consultation. Results Construct validity of the SDM coding system was successfully conducted. Oncologists demonstrated on average under 11 of 18 SDM behaviours. Behaviours seeking patient preferences were particularly rare. SDM behaviours were more apparent in consultations involving female breast cancer patients. SDM behaviour scores in combination with patient involvement preference could predict achievement of patient involvement preference but not overall patient satisfaction. Although there was no overall relationship between patient anxiety and SDM scores, it did appear that physicians may change SDM behaviour according to patient factors including anxiety. Conclusion Our findings reinforce the importance of the doctor in facilitating shared decision making in oncology consultations. [ABSTRACT FROM AUTHOR]

Infant and young child feeding (IYCF) practices determine infant growth, development and health. Despite global recommendations for exclusive breastfeeding until 6 months, adherence rates are low worldwide for different reasons, largely dependent on environment. In low‐income countries, inappropriate IYCF leads to poor nutrition status. This study examined IYCF practices and nutrition outcomes in rural farming households in Tanzania before and after harvest. Mothers and their infants were recruited from two regions in Tanzania. Demographics, health status, IYCF practices, anthropometrics and haemoglobin were measured; preharvest and postharvest. Regression analysis modelled the relationship between IYCF and nutrition outcomes. Despite high rates of breastfeeding a large proportion did not meet early initiation of breastfeeding and minimum acceptable diet standards. Undernutrition was high with 30–40% of infants classified as stunted depending on season, and the majority (81%) were anaemic. Early initiation of breastfeeding was associated with higher Length‐for‐age z‐score and weight‐for‐age z‐score and lower risk of stunting and underweight (p < 0.05). The introduction of fluids other than breast milk in the first 3 days after birth was associated with lower weight‐for‐age z‐score and increased underweight (p < 0.05). Maternal age and height were strongly and positively associated with child anthropometrics. Findings confirm the importance of early infant feeding practices for growth and development and emphasize the significance of mother's nutrition status in relation to infant health. Future interventions should focus on improving maternal nutrition status before, during and after pregnancy as well as educating and supporting mothers to adopt appropriate infant feeding including breastfeeding practices for the prevention of undernutrition.

Excessive gestational weight gain (GWG) is a risk factor for several adverse pregnancy outcomes, including macrosomia. Diet is one of the few modifiable risk factors identified. However, most dietary assessment methods are impractical for use in maternal care. This study evaluated whether a short dietary screening questionnaire could be used as a predictor of excessive GWG in a cohort of Icelandic women. The dietary data were collected in gestational weeks 11–14, using a 40‐item food frequency screening questionnaire. The dietary data were transformed into 13 predefined dietary risk factors for an inadequate diet. Stepwise backward elimination was used to identify a reduced set of factors that best predicted excessive GWG. This set of variables was then used to calculate a combined dietary risk score (range 0–5). Information regarding outcomes, GWG (n = 1,326) and birth weight (n = 1,651), was extracted from maternal hospital records. In total, 36% had excessive GWG (Icelandic criteria), and 5% of infants were macrosomic (≥4,500 g). A high dietary risk score (characterized by a nonvaried diet, nonadequate frequency of consumption of fruits/vegetables, dairy, and whole grain intake, and excessive intake of sugar/artificially sweetened beverages and dairy) was associated with a higher risk of excessive GWG. Women with a high (≥4) versus low (≤2) risk score had higher risk of excessive GWG (relative risk = 1.23, 95% confidence interval, CI [1.002, 1.50]) and higher odds of delivering a macrosomic offspring (odds ratio = 2.20, 95% CI [1.14, 4.25]). The results indicate that asking simple questions about women's dietary intake early in pregnancy could identify women who should be prioritized for further dietary counselling and support.

Vitamin D deficiency has adverse health effects in young children. Our aims were to determine predictors of vitamin D status and then to use these factors to develop a practical tool to predict low 25(OH)D concentrations in preschool New Zealand children. A cross-sectional sample of 1329 children aged 2 to <5 years were enrolled from throughout New Zealand in late-winter to spring 2012. 25-Hydroxyvitamin D (25(OH)D) was measured on dried blood spot (DBS) samples collected using finger-prick sampling. Caregivers completed a questionnaire. Mean (SD) DBS 25(OH)D concentration was 52(19)nmol/L. 25(OH)D < 25 nmol/L was present in 86(7%), 25(OH)D < 50 nmol/L in 642(48%), 25(OH)D 50- < 75 nmol/L in 541(41%) and 25(OH)D > 75 nmol/L in 146(11%) of children. Factors independently associated with the risk of 25(OH)D < 25 nmol/L were female gender (OR 1.92,95%CI 1.17-3.14), other non-European ethnicities (not including Māori or Pacific) (3.51,1.89-6.50), had olive-dark skin colour (4.52,2.22-9.16), did not take vitamin D supplements (2.56,1.06-6.18), had mothers with less than secondary-school qualifications (5.00,2.44-10.21) and lived in more deprived households (1.27,1.06-1.53). Children who drank toddler milk (vitamin D fortified cow's milk formula marketed to young children) had a zero risk of 25(OH)D < 25 nmol/L. The predictive tool identified children at risk of 25(OH)D < 25 nmol/L with sensitivity 42%, specificity 97% and ROC area-under-curve 0.76(95%CI 0.67-0.86, p < 0.001). Predictors of low vitamin D status were consistent with those identified in previous studies of New Zealand children. The tool had insufficient predictive ability for use in clinical situations, and suggests a need to promote safe, inexpensive testing to determine vitamin D status in preschool children.

Prenatal maternal stress can adversely affect birth outcomes, likely reflecting effects of maternal stress hormones on fetal development. Maternal stress might also induce behavioural changes, such as dietary change, that might influence fetal development. Few studies have documented relationships between stress and dietary change in pregnancy. We analysed stress and dietary change among 222 pregnant women exposed to the 2011 Queensland Floods. We assessed women's objective hardship, subjective distress and cognitive appraisal of the disaster; changes in their diets and their associations with infants' gestational age, weight, length and head circumference at birth, head circumference to birth length ratio (HC/BL) and ponderal index. Greater objective hardship was correlated with more negative dietary change, skipped meals and skipped multivitamins. There were no direct effects of stress or dietary change on birth outcomes. However, we observed an interactive effect of dietary change and exposure timing on head circumference for gestational age (HC for GA) ( p = 0.010) and a similar trend for HC/BL ( p = 0.064). HC for GA and HC/BL were larger among children whose mothers experienced negative changes to their diet in early pregnancy compared with later pregnancy, consistent with a 'head-sparing' response with early gestation exposure. Further analyses indicated that dietary change mediates the relationship between objective hardship because of the floods and these outcomes. This is the first report of relationships among an independent stressor, dietary change and birth outcomes. It highlights another possible mechanism in the relationship between prenatal maternal stress and child development that could guide future research and interventions. [ABSTRACT FROM AUTHOR]
