Abstract
INTRODUCTION Childhood obesity is a major public health concern and sugar-sweetened beverages (SSBs) are a known contributor. SSB taxation and food labelling have been proposed as policies to reduce consumption by changing purchasing behaviours. The study aimed to analyse caregivers' preferences on commonly purchased SSBs in Australia and to determine the effect of price increases and teaspoon labelling on their purchasing intentions. METHODS We used a discrete choice experiment (DCE) to obtain data about choices between SSB and non-SSB alternatives. 563 caregivers, who had young children aged 3-7 years, completed the experiment online. 286 were randomly allocated to receive choice sets with plain labelling while 277 were assigned to teaspoon labelling. Each participant completed nine choice scenarios where they chose between six SSB and non-SSB beverage options or a no-beverage option, with beverage prices varying between scenarios. While hypothetical, price and teaspoon labelling for sugar content for each beverage was obtained from an informal market survey. Responses from the DCE were modelled using random parameters logit within a random utility theory framework. Household income and children's consumption volumes of soft drink were used to explore preference heterogeneity. RESULTS Using mixed logit as the final model, we found that higher reduction in intended purchases was observed for soft drink and fruit drink in teaspoon labelling than it was in plain labelling. Participants exposed to teaspoon labelling intended to purchase less of flavoured milk and fruit juice compared to those exposed to plain labelling. Compared to baseline prices, a hypothetical 20% increase in SSB prices and the presentation of 'teaspoons of sugar' labelling were predicted to reduce intentional SSB purchases and increase intentional non-SSB purchases. Within each labelling group, there were no significant differences of intentional purchases between the highest and the lowest income quintile, high and low consumers of soft drinks. However, compared to plain labelling, teaspoon labelling was predicted to strongly influence intentional purchases of SSBs and non-SSBs. CONCLUSION This study suggests that a policy to increase SSB price and include teaspoon labelling would lead to a reduced consumption of SSBs and increased consumption of non-SSBs.

Abstract
INTRODUCTION The perinatal-postnatal family environment is associated with childhood outcomes including impacts on physical and mental health and educational attainment. Family longitudinal cohort studies collect in-depth data that can capture the influence of an era on family lifestyle, mental health, chronic disease, education and financial stability to enable identification of gaps in society and provide the evidence for changes in government in policy and practice. METHODS AND ANALYSIS The Queensland Family Cohort (QFC) is a prospective, observational, longitudinal study that will recruit 12 500 pregnant families across the state of Queensland (QLD), Australia and intends to follow-up families and children for three decades. To identify the immediate and future health requirements of the QLD population; pregnant participants and their partners will be enrolled by 24 weeks of gestation and followed up at 24, 28 and 36 weeks of gestation, during delivery, on-ward, 6 weeks postpartum and then every 12 months where questionnaires, biological samples and physical measures will be collected from parents and children. To examine the impact of environmental exposures on families, data related to environmental pollution, household pollution and employment exposures will be linked to pregnancy and health outcomes. Where feasible, data linkage of state and federal government databases will be used to follow the participants long term. Biological samples will be stored long term for future discoveries of biomarkers of health and disease. ETHICS AND DISSEMINATION Ethical approval has been obtained from the Mater Research Ethics (HREC/16/MHS/113). Findings will be reported to (1) QFC participating families; (2) funding bodies, institutes and hospitals supporting the QFC; (3) federal, state and local governments to inform policy; (4) presented at local, national and international conferences and (5) disseminated by peer-review publications.

Abstract
OBJECTIVE To assess the quantity and focus of recent empirical research regarding the effect of micronutrient supplementation on live birth outcomes in low-risk pregnancies from high-income countries. DESIGN A systematic quantitative literature review. SETTING Low-risk pregnancies in World Bank-classified high-income countries, 2019. RESULTS Using carefully selected search criteria, a total of 2475 publications were identified, of which seventeen papers met the inclusion criteria for this review. Data contributing to nine of the studies were sourced from four cohorts; research originated from ten countries. These cohorts exhibited a large number of participants, stable data and a low probability of bias. The most recent empirical data offered by these studies was 2011; the most historical was 1980. In total, fifty-five categorical outcome/supplement combinations were examined; 67·3 % reported no evidence of micronutrient supplementation influencing selected outcomes. CONCLUSIONS A coordinated, cohesive and uniform empirical approach to future studies is required to determine what constitutes appropriate, effective and safe micronutrient supplementation in contemporary cohorts from high-income countries, and how this might influence pregnancy outcomes.

Abstract
BACKGROUND Trace elements are an essential requirement for human health and development and changes in trace element status have been associated with pregnancy complications such as gestational diabetes mellitus (GDM), pre-eclampsia (PE), fetal growth restriction (FGR), and preterm birth. Elemental metabolomics, which involves the simultaneous quantification and characterisation of multiple elements, could provide important insights into these gestational disorders. METHODS This study used an Agilent 7900 inductively coupled plasma mass spectrometer (ICP-MS) to simultaneously measure 68 elements, in 166 placental cord blood samples collected from women with various pregnancy complications (control, hypertensive, PE, GDM, FGR, pre-term, and post-term birth). RESULTS There were single element differences across gestational outcomes for elements Mg, P, Cr, Ni, Sr, Mo, I, Au, Pb, and U. Hypertensive and post-term pregnancies were significantly higher in Ni concentrations when compared to controls (control = 2.74 μg/L, hypertensive = 6.72 μg/L, post-term = 7.93 μg/L, p < 0.05), iodine concentration was significantly higher in post-term pregnancies (p < 0.05), and Pb concentrations were the lowest in pre-term pregnancies (pre-term = 2.79 μg/L, control = 4.68 μg/L, PE = 5.32 μg/L, GDM = 8.27 μg/L, p < 0.01). Further analysis was conducted using receiver operating characteristic (ROC) curves for differentiating pregnancy groups. The ratio of Sn/Pb showed the best diagnostic power in discriminating between control and pre-term birth with area under the curve (AUC) 0.86. When comparing control and post-term birth, Mg/Cr (AUC = 0.84), and Cr (AUC = 0.83) had the best diagnostic powers. In pre-term and post-term comparisons Ba was the best single element (81.5%), and P/Cu provided the best ratio (91.7%). CONCLUSIONS This study has shown that analysis of multiple elements can enable differentiation between fetal cord blood samples from control, hypertensive, PE, GDM, FGR, pre and post-term pregnancies. This data highlights the power of elemental metabolomics and provides a basis for future gestational studies.

Immunisation status of children presenting to the emergency department: Linkage of a longitudinal birth cohort with national immunisation data. J Paediatr Child Health 2019; 55:772-780.

Abstract
AIM To describe the relationship between emergency department (ED) diagnosis of infectious disease and immunisation status in children ≤5 years. We also aimed to demonstrate feasibility of proof-of-concept linkage between disparate databases. METHODS Data from a cohort of 3404 children born in Southeast Queensland/Far North New South Wales between 2006 and 2011 were linked to Australian Childhood Immunisation Registry data and Emergency Department Information System data for presentations between 2006 and 2014. Immunisation status was assigned using the 2009 National Immunisation Program schedule. RESULTS Of 1490 children (79% of those consented) with data on immunisation status, 87.2 and 84.6% were fully immunised by 12 and 24 months, respectively. Adding partially immunised children increased this to 93.2 and 91.4% at 12 and 24 months, respectively. Nearly two-thirds of all children made at least one ED presentation. Children presenting to ED with an infectious disease did not differ in immunisation status compared to children with other (non-infectious disease type) presentations but were younger, more likely to live with other children and had a longer ED stay and higher admission rate. Respiratory syncytial virus (RSV) was more frequently diagnosed in unimmunised children. CONCLUSIONS In an existing birth cohort, immunisation rates were lower than the national average. RSV was more prevalent in unimmunised children presenting to ED, but immunisation status was not significantly associated with other infectious disease presentations. Linkage between national immunisation data and Australian ED data is feasible and has the potential to identify previously unrecognised factors related to child immunisation status and health-care utilisation.

Abstract
Prevalence of asthma in Australian children is amongst the highest in the world. Although breastfeeding positively influences infant immunity, early introduction of Milk Other than Breast Milk (MOTBM) may also play an important role in the development of Asthma. The aim of this study was to investigate the association between the introduction of MOTBM in the first six months after birth and the development of reported persistent asthma in 3-year olds. A sample of 1121 children was extracted from the Environments for Healthy Living longitudinal birth cohort study. Introduction of MOTBM during the first six months after birth increased almost two-fold the risk of development of persistent asthma after adjusting for other covariates (Adjusted Relative Risk (ARR): 1.71, 95% CI: 1.03⁻2.83, p = 0.038). This study indicates that the introduction of MOTBM in the first six months of life is a risk factor for asthma incidence among 3-year old children. This result is important in explaining the benefits of breastfeeding as part of public health interventions to encourage mothers to increase breastfeeding initiation and duration, and avoid the introduction of MOTBM in the first six months after childbirth.

Abstract
BACKGROUND Against a background of changing family structures and socioeconomic demands in contemporary families, fathers are more actively engaged in meal preparation and feeding of their children, yet in research studies targeting improvement in nutrition and feeding practices fathers are under-represented. Among possible explanations for this bias are acceptability of research projects and accessibility to male research participants. The aims of this study were to identify (i) fathers' preferences for participation in child nutrition research and interventions and (ii) the potential to recruit fathers through their workplaces with the possibility of delivering interventions through those workplaces. METHODS This paper draws on two independent yet linked studies that explored fathers' roles in family feeding, and intervention studies aimed at supporting father's dietary knowledge and feeding practices. For Study 1 (conducted first) secondary data analysis was conducted on survey data (n = 463 fathers of preschool children) to determine preferences related to type of program, delivery mode, and location and timing. For Study 2 six focus groups and one individual interview were conducted with n = 28 fathers to determine acceptability of recruitment of fathers working in traditionally blue-collar occupations and service industries (as defined by the Australian Bureau of Statistics) and potential of intervention delivery through their workplaces. RESULTS Fathers were engaged in child feeding and indeed sought nutrition-related information. Fathers indicated a preference for family-focused and online delivery of interventions. Whilst potential to recruit through blue-collar workplaces was evident, participants were divided in their views about the acceptability of interventions conducted through the workplace. There was a sense of support for the logic of such interventions but the focus group participants in this study showed only modest enthusiasm for the idea. CONCLUSIONS With limited support for the workplace as an intervention setting, further systematic exploration of technology-based intervention design and engagement is warranted. Based on findings, interventions should target a) content that is focused on the family and how to make changes at the family level, rather than the father individually; and b) online delivery, such as Apps or online video chat sessions, for convenience and to facilitate sharing of information with family members.

Abstract
Background To measure rates of parental-report of allergic disorders and ED presentations for allergic disorders in children, and to describe factors associated with either. Methods An existing cohort of 3404 children born between 2006 and 2011 (Environments for Healthy Living) with prospectively collected pre-natal, perinatal and follow-up data were linked to i) nationwide Medicare and pharmaceutical data and ii) Emergency Department (ED) data from four hospitals in Australia. Parental-reported allergy was assessed in those who returned follow-up questionnaires. ED presentation was defined as any presentation for a suite of allergic disorders, excluding asthma. Univariate analysis and multivariate logistic regression were used to descibe risk factors for both parental-reported allergy and ED presentation for an allergic disorder. Results The incidence of parental-reported child allergy at 1, 3 and 5 years of age was 7.8, 7.8 and 12.6%, respectively. Independent predictors of parental-report of allergy in multivariate analysis were parental-report of asthma (OR 2.2, 95% CI 1.4–3.4) or eczema (OR 4.3, 95% CI 3.1–6.1) and age > 6 months at introduction of solids (OR 1.3, 95% CI 1.0–1.7). Factors associated with ED presentations for allergy, which occurred in 3.6% of the cohort, were presence of maternal asthma (OR 2.3 95% CI:1.1, 4.9) and child born in spring (OR 1.7, 95% CI 1.1, 2.7). Conclusions More than 10% of children up to 5 years have a parental-reported allergic disorder, and 3.6% presented to ED. Parental-report of eczema and/or asthma and late introduction of solids were predictors of parental-report of allergy. Spring birth and maternal asthma were predictors for ED presentation for allergy.

Abstract
A better understanding of the public's preferences and what factors influence them is required if they are to be used to drive decision-making in health. This is particularly the case for service areas undergoing continual reform such as emergency and primary care. Accordingly, this study sought to determine if attitudes, socio-demographic characteristics and healthcare experiences influence the public's intentions to access care and their preferences for hypothetical emergency care alternatives. A discrete choice experiment was used to elicit the preferences of Australian adults (n=1529). Mixed logit regression analyses revealed the influence of a range of individual characteristics on preferences and service uptake choices across three different presenting scenarios. Age was associated with service uptake choices in all contexts, whilst the impact of other sociodemographics, health experience and attitudinal factors varied by context. The improvements in explanatory power observed from including these factors in the models highlight the need to further clarify their influence with larger populations and other presenting contexts, and to identify other determinants of preference heterogeneity. The results suggest social marketing programs undertaken as part of demand management efforts need to be better targeted if decision-makers are seeking to increase community acceptance of emerging service models and alternatives. Other implications for health policy, service planning and research, including for workforce planning and the possible introduction of a system of co-payments are discussed.

Contactable Non-responders Show Different Characteristics Compared to Lost to Follow-Up Participants: Insights from an Australian Longitudinal Birth Cohort Study. Matern Child Health J 2017; 20:1472-84.

Abstract
Objective This research aims to identify predictors of attrition in a longitudinal birth cohort study in Australia and assess differences in baseline characteristics and responses in subsequent follow-up phases between contactable non-responders and uncontactable non-responders deemed "lost to follow-up (LTF)". Methods 3368 women recruited from three public hospitals in Southeast Queensland and Northern New South Wales during antenatal visits in 2006-2011 completed a baseline questionnaire to elicit information on multiple domains of exposures. A follow-up questionnaire was posted to each participant at 1 year after birth to obtain mother's and child's health and development information. Multivariate logistic regression was used to model the association between exposures and respondents' status at 1 year. The effect of an inverse-probability-weighting method to adjust for non-response was studied. Results Overall attrition at 1-year was 35.4 %; major types of attrition were "contactable non-response" (27.6 %) and "LTF" (6.7 %). These two attrition types showed different responses at the 3-year follow-up and involved different predictors. Besides shared predictors (first language not English, higher risk of psychological distress, had smoked during pregnancy, higher levels of family conflict), distinguishable predictors of contactable non-responders were younger age, having moved home in the past year and having children under 16 in the household. Attrition rates increased substantially from 20 % in 2006 to 54 % in 2011. Conclusions This observed trend of increased attrition rates raises concern about the use of traditional techniques, such as "paper-based" questionnaires, in longitudinal cohort studies. The supplementary use of electronic communications, such as online survey tools and smart-device applications, could provide a better alternative.

Abstract
AIM Infants under 12 months of age are disproportionately represented amongst emergency department (ED) presentations, and infants are more likely to be frequent ED users. This study aimed to describe and identify psychosocial predictors of ED presentation in infants. METHODS A prospective birth cohort from Queensland and New South Wales (Environments for Healthy Living) was used to understand infant health service use. Baseline and 12-month questionnaire data pertaining to children born between 2006 and 2011 were used to identify predictors of ED presentation, using multiple regression analysis. RESULTS Of the 2184 children in the cohort with available baseline and 12-month data, 579 (27%) presented at least once to an ED during their first 12 months of life. Statistically significant predictors of ED presentation in the multivariate analysis included the mother having asthma (odds ratio (OR) 1.67, 95% confidence interval (CI) 1.15-2.39) and a higher Kessler-6 score (a measure of psychological distress) of the primary carer at baseline (OR 1.04, 95% CI 1.01-1.08). Maternal education level was not associated with ED presentations of infants. CONCLUSIONS This study describes maternal and child factors of children who present to the ED in the first year of life. Factors related to an infant's support system were found to be predictors for an ED presentation in the first year of life. This study emphasises the need to review the maternal medical history and psychosocial situation. There may be benefits for health-care practitioners to take the opportunity (such as during routine childhood immunisation) to perform a brief screening tool (such as the Kessler-6) to understand psychological distress experienced by mothers. This may influence the likelihood of a child presenting to an ED within the first 12 months of life.

Abstract
BACKGROUND Longitudinal research is subject to participant attrition. Systemic differences between retained participants and those lost to attrition potentially bias prevalence of outcomes, as well as exposure-outcome associations. This study examines the impact of attrition on the prevalence of child injury outcomes and the association between sociodemographic factors and child injury. METHODS Participants were recruited as part of the Environments for Healthy Living (EFHL) birth cohort study. Baseline data were drawn from maternal surveys. Child injury outcome data were extracted from hospital records, 2006-2013. Participant attrition status was assessed up to 2014. Rates of injury-related episodes of care were calculated, taking into account exposure time and Poisson regression was performed to estimate exposure-outcome associations. RESULTS Of the 2222 participating families, 799 families (36.0%) had complete follow-up data. Those with incomplete data included 137 (6.2%) who withdrew, 308 (13.8%) were lost to follow-up and 978 families (44.0%) who were partial/non-responders. Families of lower socioeconomic status were less likely to have complete follow-up data (p<0.05). Systematic differences in attrition did not result in differential child injury outcomes or significant differences between the attrition and non-attrition groups in risk factor effect estimates. Participants who withdrew were the only group to demonstrate differences in child injury outcomes. CONCLUSION This research suggests that even with considerable attrition, if the proportion of participants who withdraw is minimal, overall attrition is unlikely to affect the population prevalence estimate of child injury or measures of association between sociodemographic factors and child injury.

Abstract
Objective: Childhood obesity is a serious concern for developed and developing countries. This study aimed to assess the level of support in Australia for regulation and to assess whether systematic differences occur between individuals who support increased regulation and individuals who oppose it. Methods: An online survey (n = 563) was used to assess parental/caregiver preferences for taxation policy options and nutrition labelling designed to address the incidence of childhood obesity. Participants were parents or caregivers of young children (3 to 7 years) who were actively enrolled in an existing birth cohort study in South-East Queensland, Australia. Results: The majority of the parents (over 80%) strongly agreed or agreed with labelling food and drink with traffic light or teaspoon labelling. Support for taxation was more variable with around one third strongly supporting and a further 40% of participants equivocal about using taxation; however, a quarter strongly rejected this policy. Cluster analysis did not detect any socio-demographic differences between those who strongly supported taxation and those who did not. Conclusions: Better food labelling would be welcomed by parents to enhance food choices for their children. Taxation for health reasons would not be opposed by most parents. Implications for Public Health: Governments should consider taxation of unhealthy drinks and improved labelling to encourage healthy food purchasing.

Abstract
Objective
The aim of the present study was to compare sociodemographic characteristics of children with single versus recurrent episodes of injury and provide contemporary evidence for Australian injury prevention policy development.
Methods
Participants were identified from the Environments for Healthy Living: Griffith Birth Cohort Study 2006–11 (n = 2692). Demographic data were linked to the child’s hospital emergency and admissions data from birth to December 2013. Data were dichotomised in two ways: (1) injured or non-injured; and (2) single or recurrent episodes of injury. Multivariate logistic regression was used for analysis.
Results
The adjusted model identified two factors significantly associated with recurrent episodes of injury in children aged <3 years. Children born to mothers <25 years were almost fourfold more likely to have recurrent episodes of injury compared with children of mothers aged ≥35 years (adjusted odds ratio (aOR) = 3.68; 95% confidence interval (CI) 1.44–9.39) and, as a child’s age at first injury increased, odds of experiencing recurrent episodes of injury decreased (aOR = 0.97; 95% CI 0.94–0.99). No differences were found in sociodemographic characteristics of children aged 3–7 years with single versus recurrent episodes of injury (P > 0.1).
Conclusion
National priorities should include targeted programs addressing the higher odds of recurrent episodes of injury experienced by children aged <3 years with younger mothers or those injured in the first 18 months of life.
What is known about the topic?
Children who experience recurrent episodes of injury are at greater risk of serious or irrecoverable harm, particularly when repeat trauma occurs in the early years of life.
What does the paper add?
The present study identifies key factors associated with recurrent episodes of injury in young Australian children. This is imperative to inform evidence-based national injury prevention policy development in line with the recent expiry of the National Injury Prevention and Safety Promotion Plan: 2004–2014.
What are the implications for practitioners?
Injury prevention efforts need to target the increased injury risk experienced by families from lower socioeconomic backgrounds and, as a priority, children under 3 years of age with younger mothers and children who are injured in the first 18 months of life. These families require access to education programs, resources, equipment and support, particularly in the child’s early years. These programs could be provided as part of the routine paediatric and child health visits available to families after their child’s birth or incorporated into hospital and general practitioner injury treatment plans.

Community level predictors of physical activity among women in the preconception period. Matern Child Health J 2016; 19:1584-92.

Abstract
Although physical activity is a key behavior targeted during the preconception period given its significant impact on pregnancy/birth outcomes and psychological well-being, few women meet national guidelines. While intrapersonal factors influencing physical activity among this population have been studied, community factors remain unexplored. The objective of this study was to examine community level predictors of physical activity among preconception women. Data from Add Health were limited to women (Wave III; age 18-28; n = 7,596) and excluded respondents who were pregnant, physically disabled, and missing data. The outcome variable was ≥5 instances of moderate-vigorous physical activity (MVPA) in 1 week. Community predictor variables included neighborhood-level structural and social determinants (e.g., socio-demographic composition; landscape diversity; urbanization; access to resources; crime; vehicle availability). Multilevel logistic regression modeling was used to estimate the odds of engaging in ≥5 instances of MVPA. Few women (26 %) reported ≥5 instances of MVPA in 1 week. Adjusted multilevel analysis revealed women in the preconception period were more likely to report high MVPA when living in communities with larger population densities (OR 1.34, 95 % CI 1.02-1.77) and median household income greater than $50,000 (OR 1.33, 95 % CI 1.06-1.66). Additionally, a significant inverse trend was found between high MVPA and proportion of the community without a high school diploma. Findings suggest that neighborhood composition may have an impact on preconception physical activity status. Implications include increased efforts targeting community conditions for facilitating physical activity; ultimately, improving health among women and subsequent offspring.

Abstract
Background The longitudinal birth cohort design has yielded a substantial contribution to knowledge of child health and development. The last full review in New Zealand and Australia in 2004 identified 13 studies. Since then, birth cohort designs continue to be an important tool in understanding how intrauterine, infant and childhood development affect long-term health and well-being. This updated review in a defined geographical area was conducted to better understand the factors associated with successful quality and productivity, and greater scientific and policy contribution and scope. Methods We adopted the preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach, searching PubMed, Scopus, Cinahl, Medline, Science Direct and ProQuest between 1963 and 2013. Experts were consulted regarding further studies. Five inclusion criteria were used: (1) have longitudinally tracked a birth cohort, (2) have collected data on the child and at least one parent or caregiver (3) be based in Australia or New Zealand, (4) be empirical in design, and (5) have been published in English. Results 10665 records were initially retrieved from which 23 birth cohort studies met the selection criteria. Together these studies recruited 91,196 participants, with 38,600 mothers, 14,206 fathers and 38,390 live births. Seventeen studies were located in Australia and six in New Zealand. Research questions initially focused on the perinatal period, but as studies matured, longer-term effects and outcomes were examined. Conclusions This review demonstrates the significant yield from this effort both in terms of scientific discovery and social policy impact. Further opportunities have been recognised with cross-study collaboration and pooling of data between established and newer studies and international studies to investigate global health determinants.

Abstract
This study examined the relationship between home risk and hospital treated injury in Australian children up to five years old. Women with children between two and four years of age enrolled in the Environments for Healthy Living (EFHL): Griffith Birth Cohort Study were invited to complete a Home Injury Prevention Survey from March 2013 to June 2014. A total home risk score (HRS) was calculated and linked to the child's injury related state-wide hospital emergency and admissions data and EFHL baseline demographic surveys. Data from 562 households relating to 566 child participants were included. We found an inverse relationship between home risk and child injury, with children living in homes with the least injury risk (based on the absence of hazardous structural features of the home and safe practices reported) having 1.90 times the injury rate of children living in high risk homes (95% CI 1.15-3.14). Whilst this appears counter-intuitive, families in the lowest risk homes were more likely to be socio-economically disadvantaged than families in the highest risk homes (more sole parents, lower maternal education levels, younger maternal age and lower income). After adjusting for demographic and socio-economic factors, the relationship between home risk and injury was no longer significant (p > 0.05). Our findings suggest that children in socio-economically deprived families have higher rates of injury, despite living in a physical environment that contains substantially fewer injury risks than their less deprived counterparts. Although measures to reduce child injury risk through the modification of the physical environment remain an important part of the injury prevention approach, our study findings support continued efforts to implement societal-wide, long term policy and practice changes to address the socioeconomic differentials in child health outcomes.

Abstract
Background Expenditure on dental and oral health services in Australia is $3.4 billion AUD annually. This is the sixth highest health cost and accounts for 7 % of total national health expenditure. Approximately 49 % of Australian children aged 6 years have caries experience in their deciduous teeth and this is rising. The aetiology of dental caries involves a complex interplay of individual, behavioural, social, economic, political and environmental conditions, and there is increasing interest in genetic predisposition and epigenetic modification. Methods The Oral Health Sub-study; a cross sectional study of a birth cohort began in November 2012 by examining mothers and their children who were six years old by the time of initiation of the study, which is ongoing. Data from detailed questionnaires of families from birth onwards and data on mothers’ knowledge, attitudes and practices towards oral health collected at the time of clinical examination are used. Subjects’ height, weight and mid-waist circumference are taken and Body Mass Index (BMI) computed, using an electronic Bio-Impedance balance. Dental caries experience is scored using the International Caries Detection and Assessment System (ICDAS). Saliva is collected for physiological measures. Salivary Deoxyribose Nucleic Acid (DNA) is extracted for genetic studies including epigenetics using the SeqCap Epi Enrichment Kit. Targets of interest are being confirmed by pyrosequencing to identify potential epigenetic markers of caries risk. Discussion This study will examine a wide range of potential determinants for childhood dental caries and evaluate inter-relationships amongst them. The findings will provide an evidence base to plan and implement improved preventive strategies.

Abstract
The aim of the study was to describe the validity of parent's self-reported responses to questions on home safety practices for children of 2-4 years. A cross-sectional validation study compared parent's self-administered responses to items in the Home Injury Prevention Survey with home observations undertaken by trained researchers. The relationship between the questionnaire and observation results was assessed using percentage agreement, sensitivity, specificity, positive predictive value, negative predictive value and intraclass correlation coefficients. Percentage agreements ranged from 44% to 100% with 40 of the total 45 items scoring higher than 70%. Sensitivities ranged from 0% to 100%, with 27 items scoring at least 70%. Specificities also ranged from 0% to 100%, with 33 items scoring at least 70%. As such, the study identified a series of self-administered home safety questions that have sensitivities, specificities and predictive values sufficiently high to allow the information to be useful in research and injury prevention practice.

AUST HEALTH REV 2015; 39:136-145. [DOI: 10.1071/ah14108] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2014] [Accepted: 10/29/2014] [Indexed: 11/23/2022]
Abstract
Objective The aim of the present study was to examine the relationship between socioeconomic status (SES) and child general practitioner (GP) visits in the first 12 months of life. Methods A longitudinal analysis of 1202 mother and child dyads was conducted as part of the Environments for Healthy Living study from south-east Queensland, Australia, for participants enrolled between 2006 and 2009. Maternally reported survey data (sociodemographic and child health information) were linked with individual Medical Benefits Scheme data from birth to 12 months, identifying GP service use. Results On average, children visited the GP 10.2 times in the first 12 months of life. An inverse relationship was found for SES and child GP visits, with maternal education and child gender the strongest predictors of the total number of GP visits. Almost 70% of participants had all GP consultations bulk billed and only 3.5% paid more than A$100 in total. Conclusions Children from lower SES families may have a greater need for health services due to higher rates of illness and injury. Bulk billing and low-cost access to GP services, regardless of length of consultation, improve equity of access; however, indirect costs may prevent low-income mothers from accessing care for their child when needed. What is known about the topic? The relationship between health and SES, and the influence that health service use can have on this relationship, are well recognised. Previous studies on adult populations in Australia suggest that people of lower SES have more frequent GP consultations due to greater exposure to health risk. However, consultation times are often shorter because short consultations are more likely to be bulk billed, which is resulting in ongoing unmet need. Early childhood visits to the GP can strongly influence long-term health outcomes; however, relatively few studies have examined GP service use among children in Australia. What does this paper add? This paper builds on current knowledge by providing valuable insights into GP service use in the first 12 months of life. It provides evidence to suggest that the relationship between SES and health risk already exists in the first 12 months of life and that bulk billing and low-cost access to GP services improves equity of access. It also highlights the importance of health policy and practice that enables GP service utilisation based on need rather than ability to pay. What are the implications for practitioners? Policies and practice that promote equity of access, such as bulk billing for lower SES families, can assist in improving long-term health outcomes for disadvantaged populations. Greater equity with regard to length of consultation and bulk billing for adults may assist in reducing the disparities in health outcomes between the higher and lower SES populations. Furthermore, indirect costs and the availability of appropriate services for specific groups, such as low income, rural and remote and linguistically and culturally diverse populations, may also be important barriers to access.

Abstract
OBJECTIVE To compare sun protection by Australian-born and migrant mothers of three-year-old children. METHODS Australian-born and migrant mothers taking part in the Environments for Healthy Living prospective birth-cohort study were asked standard questions about their child's sun protection. Children were given a skin cancer susceptibility score based on grandparents' ethnic origin. Logistic regression was used to estimate odds ratios (ORs) to measure the association of sun protection of children according to mothers' migrant status adjusted for socio-demographic characteristics. RESULTS A total of 613 Australian-born and 224 migrant mothers of three-year-old children were studied. Mothers who had migrated less than four years ago were more likely to allow their three-year-old to spend more than two hours outdoors between 10 am and 3 pm compared to Australian-born mothers (OR=2.80, 95%CI 1.20-6.57). Mothers from high latitude countries (>45 degrees) were more likely to apply sunscreen to their child than those from lower latitude countries (OR=3.15, 95%CI 1.03-9.61). CONCLUSIONS AND IMPLICATIONS Strategies should aim to increase general awareness about the need for sun protection of young children, and recent migrants should be alerted to the harms of excessive sun exposure.

Abstract
BACKGROUND Long-term obesity after pregnancy is associated with obesity prior to pregnancy and retention of weight postpartum. This study aims to identify socioeconomic differences in prepregnancy body mass index, quantify the impact of prepregnancy obesity on birth outcomes, and identify determinants of postpartum weight retention. METHODS A total of 2231 pregnant women, recruited from three public hospitals in Southeast Queensland in Australia during antenatal clinic visits, completed a questionnaire to elicit information on demographics, socioeconomic and behavioural characteristics. Perinatal information was extracted from hospital records. A follow-up questionnaire was completed by each participant at 12 months after the birth to obtain the mother's postpartum weight, breastfeeding pattern, dietary and physical activity characteristics, and the child's health and development information. Multivariate logistic regression method was used to model the association between prepregnancy obesity and outcomes. RESULTS Being overweight or obese prepregnancy was strongly associated with socioeconomic status and adverse behavioural factors. Obese women (18% of the cohort) were more likely to experience gestational diabetes, preeclampsia, cesarean delivery, and their children were more likely to experience intensive- or special-care nursery admission, fetal distress, resuscitation, and macrosomia. Women were more likely to retain weight postpartum if they consumed three or fewer serves of fruit/vegetables per day, did not engage in recreational activity with their baby, spent less than once a week on walking for 30 minutes or more or spent time with friends less than once per week. Mothers who breastfed for more than 3 months had reduced likelihood of high postpartum weight retention. CONCLUSIONS Findings provide additional specificity to the increasing evidence of the predisposition of obesity prepregnancy on adverse maternal and perinatal outcomes. They may be used to target effective behavioural change interventions to address obesity in women.

Abstract
BACKGROUND The role of fathers in shaping their child's eating behaviour and weight status through their involvement in child feeding has rarely been studied. This study aims to describe fathers' perceived responsibility for child feeding, and to identify predictors of how frequently fathers eat meals with their child. METHODS Four hundred and thirty-six Australian fathers (M age = 37 years, SD = 6 years; 34% university educated) of a 2-5-year-old child (M age = 3.5 years, SD = 0.9 years; 53% boys) were recruited via contact with mothers enrolled in existing research projects or a university staff and student email list. Data were collected from fathers via a self-report questionnaire. Descriptive and hierarchical linear regression analyses were conducted. RESULTS The majority of fathers reported that the family often/mostly ate meals together (79%). Many fathers perceived that they were responsible at least half of the time for feeding their child in terms of organizing meals (42%); amount offered (50%) and deciding if their child eats the 'right kind of foods' (60%). Time spent in paid employment was inversely associated with how frequently fathers ate meals with their child (β = -0.23, P < 0.001); however, both higher perceived responsibility for child feeding (β = 0.16, P < 0.004) and a more involved and positive attitude toward their role as a father (β = 0.20, P < 0.001) were positively related to how often they ate meals with their child, adjusting for a range of paternal and child covariates, including time spent in paid employment. CONCLUSIONS Fathers from a broad range of educational backgrounds appear willing to participate in research studies on child feeding. Most fathers were engaged and involved in family meals and child feeding. This suggests that fathers, like mothers, should be viewed as potential agents for the implementation of positive feeding practices within the family.

Abstract
OBJECTIVES To examine the association of maternal pregravid body mass index (BMI) and child offspring, all-cause hospitalisations in the first 5 years of life. METHODS Prospective birth cohort study. From 2006 to 2011, 2779 pregnant women (2807 children) were enrolled in the Environments for Healthy Living: Griffith birth cohort study in South-East Queensland, Australia. Hospital delivery record and self-report baseline survey of maternal, household and demographic factors during pregnancy were linked to the Queensland Hospital Admitted Patients Data Collection from 1 November 2006 to 30 June 2012, for child admissions. Maternal pregravid BMI was classified as underweight (<18.5 kg m(-)(2)), normal weight (18.5-24.9 kg m(-)(2)), overweight (25.0-29.9 kg m(-)(2)) or obese (⩾30 kg m(-)(2)). Main outcomes were the total number of child hospital admissions and ICD-10-AM diagnostic groupings in the first 5 years of life. Negative binomial regression models were calculated, adjusting for follow-up duration, demographic and health factors. The cohort comprised 8397.9 person years (PYs) follow-up. RESULTS Children of mothers who were classified as obese had an increased risk of all-cause hospital admissions in the first 5 years of life than the children of mothers with a normal BMI (adjusted rate ratio (RR) =1.48, 95% confidence interval 1.10-1.98). Conditions of the nervous system, infections, metabolic conditions, perinatal conditions, injuries and respiratory conditions were excessive, in both absolute and relative terms, for children of obese mothers, with RRs ranging from 1.3-4.0 (PYs adjusted). Children of mothers who were underweight were 1.8 times more likely to sustain an injury or poisoning than children of normal-weight mothers (PYs adjusted). CONCLUSION RESULTS suggest that if the intergenerational impact of maternal obesity (and similarly issues related to underweight) could be addressed, a significant reduction in child health care use, costs and public health burden would be likely.

Abstract
The use of pregnancy-specific multivitamin supplements is widely recommended to support maternal homeostasis during pregnancy. Our objective was to investigate whether multivitamin use during pregnancy is associated with a reduced risk of pre-eclampsia. The effect of multivitamin use on incidence of pre-eclampsia in lean and overweight/obese women was analysed using data collected between 2006 and 2011 as part of the Environments for Healthy Living Project, Griffith University, Australia. A total of 2261 pregnancies were included in the analysis with pre-eclampsia reported in 1.95% of subjects. Body mass index (BMI) ≥ 25 was associated with a 1.97-fold [95% confidence interval (CI): 0.93, 4.16] increase in pre-eclampsia risk. First trimester multivitamin use was reported by 31.8% of women and after adjustment, was associated with a 67% reduction in pre-eclampsia risk (95%CI: 0.14, 0.75). Stratification by BMI demonstrated a 55% reduction in pre-eclampsia risk (95%CI: 0.30, 0.86) in overweight (BMI: 25-29.9) and 62% risk reduction (95%CI: 0.16, 0.92) in obese (BMI: ≥30) cohorts that supplemented with multivitamins in the first trimester of pregnancy. This finding may be particular to the Australian population and reflect inherent nutritional deficits. First trimester folate supplementation was found to reduce pre-eclampsia incidence [adjusted odds ratios (AOR) 0.42 95%CI: 0.13, 0.98] and demonstrated significance upon stratification by overweight status for women with BMI >25 (AOR 0.55 95%CI: 0.31, 0.96). These results support the hypothesis that multivitamin supplementation may be beneficial in reducing the incidence of pre-eclampsia during pregnancy and be of particular importance for those with a BMI ≥25.

Abstract
BACKGROUND Childhood obesity is a recognised public health problem and around 25% of Australian children are overweight or obese. A major contributor is the obesogenic environment which encourages over consumption of energy dense nutrient poor food. Taxation is commonly proposed as a mechanism to reduce consumption of poor food choices and hence reduce rates of obesity and overweight in the community. METHODS/DESIGN An economic model will be developed to assess the lifetime benefits and costs to a cohort of Australian children by reducing energy dense nutrient poor food consumption through taxation mechanisms. The model inputs will be derived from a series of smaller studies. Food options for taxation will be derived from literature and expert opinion, the acceptability and impact of price changes will be explored through a Citizen's Jury and a discrete choice experiment and price elasticities will be derived from the discrete choice experiment and consumption data. DISCUSSION The health care costs of managing rising levels of obesity are a challenge for all governments. This study will provide a unique contribution to the international knowledge base by engaging a variety of robust research techniques, with a multidisciplinary focus and be responsive to consumers from diverse socio-economic backgrounds.

Abstract
BACKGROUND The Environments for Healthy Living (EFHL) study is a repeated sample, longitudinal birth cohort in South East Queensland, Australia. We describe the sample characteristics and profile of maternal, household, and antenatal exposures. Variation and data stability over recruitment years were examined. METHODS Four months each year from 2006, pregnant women were recruited to EFHL at routine antenatal visits on or after 24 weeks gestation, from three public maternity hospitals. Participating mothers completed a baseline questionnaire on individual, familial, social and community exposure factors. Perinatal data were extracted from hospital birth records. Descriptive statistics and measures of association were calculated comparing the EFHL birth sample with regional and national reference populations. Data stability of antenatal exposure factors was assessed across five recruitment years (2006-2010 inclusive) using the Gamma statistic for ordinal data and chi-squared for nominal data. RESULTS Across five recruitment years 2,879 pregnant women were recruited which resulted in 2904 live births with 29 sets of twins. EFHL has a lower representation of early gestational babies, fewer still births and a lower percentage of low birth weight babies, when compared to regional data. The majority of women (65%) took a multivitamin supplement during pregnancy, 47% consumed alcohol, and 26% reported having smoked cigarettes. There were no differences in rates of a range of antenatal exposures across five years of recruitment, with the exception of increasing maternal pre-pregnancy weight (p=0.0349), decreasing rates of high maternal distress (p=0.0191) and decreasing alcohol consumption (p<0.0001). CONCLUSIONS The study sample is broadly representative of births in the region and almost all factors showed data stability over time. This study, with repeated sampling of birth cohorts over multiple years, has the potential to make important contributions to population health through evaluating longitudinal follow-up and within cohort temporal effects.
