Long-term effectiveness of the midwifery initiated oral health-dental service program on maternal oral health knowledge, preventative dental behaviours and the oral health status of children in Australia.

BACKGROUND: The Midwifery Initiated Oral Health-Dental Service was developed to train midwives to promote maternal oral health, and a large trial showed it substantially improved the oral health, knowledge and behaviours of pregnant women. AIM: Evaluate the long-term effectiveness of the program (post-trial) on maternal oral health knowledge, dental behaviours, and early childhood caries in offspring. METHODS: A prospective cohort study involving 204 women and children 3-4 years (followed after trial) was conducted in Sydney, Australia from 2017 to 2019. RESULTS: The program did not have a significant impact on the study measures. Mothers who received the program did have comparatively better knowledge around preventative behaviours to reduce early childhood caries and significantly more mothers were engaging in a key behaviour of using a cup to feed their child. Overall maternal oral health knowledge and level of education did have a protective effect on the dental decay of children. Higher knowledge and levels of education reduced the odds of having a dmft of one or more by over half (OR 0.473), and almost 80% (OR 0.212) respectively. CONCLUSIONS: Although the MIOH-DS program was not effective, there is still value in exploring other complementary interventions to improve maternal oral health, especially for disadvantaged families. Future research should focus on co-designing an antenatal and postnatal oral health intervention and exploring its long-term impact on the oral health of children.

Perceptions and Practices of Oral Health Care Professionals in Preventing and Managing Childhood Obesity.

In this study, we aimed to explore the perceptions of oral health care professionals (OHCPs) on childhood overweight and obesity screening and management in oral health settings in the Greater Sydney region in New South Wales, Australia. OHCPs involved in the Healthy Smiles Healthy Kids (HSHK) birth cohort study were purposively selected for this nested qualitative study. A sample of 15 OHCPs completed the face-to-face interviews, and thematic analysis was undertaken to identify and analyse the contextual patterns and themes. Three major themes emerged: (1) obesity prevention and management in dental practice; (2) barriers and enablers to obesity prevention and management in dental settings; and (3) the role of oral health professionals in promoting healthy weight status. This study found that OHCPs are well-positioned and supportive in undertaking obesity screening and management in their routine clinical practice. However, their practices are limited due to barriers such as time constraints, limited knowledge, and limited referral pathways. Strategies including capacity building of OHCPs, development of appropriate training programs and resources, and identification of a clear specialist referral pathway are needed to address the current barriers. This study provides an insight into opportunities for the oral health workforce in promoting healthy weight status among children.

Early life and socio-economic determinants of dietary trajectories in infancy and early childhood - results from the HSHK birth cohort study.

BACKGROUND: Early childhood is a period when dietary behaviours are established. This study aimed to examine the longitudinal intake of core and discretionary foods and identify early life and socio-economic factors influencing those intakes. METHODS: Mother-infant dyads (n = 934) from the Healthy Smiles Healthy Kids study, an ongoing birth cohort study, were interviewed. The information on 'weekly frequency of core and discretionary foods intake' using a food frequency questionnaire was collected at 4 months, 8 months, 1 year, 2 years and 3 years age points. Group-based trajectory modelling analyses were performed to identify diet trajectories for 'core' and 'discretionary' foods respectively. A multinomial logistic regression was performed to identify the maternal and child-related predictors of resulting trajectories. RESULTS: The intake of core and discretionary foods each showed distinct quadratic (n = 3) trajectories with age. Overall, core foods intake increased rapidly in the first year of life, followed by a decline after age two, whereas discretionary foods intake increased steadily across the five age points. Multiparity (Relative Risk (RR): 0.46, 95%CI: 0.27-0.77), non-English speaking ethnicity of mother (RR: 0.66, 95%CI: 0.47-0.91) and having a single mother (RR: 0.40, 95%CI: 0.18-0.85) were associated with low trajectories of core foods intake whereas older maternal age (RR: 1.05, 95%CI: 1.01-1.08) and longer breastfeeding duration (RR: 1.02, 95%CI: 1.00-1.03) were associated with higher trajectories of core foods intake. Also, multiparity (RR 2.63, 95%CI: 1.47-4.70), low maternal education (RR 3.01, 95%CI: 1.61-5.65), and socio-economic disadvantage (RR 2.69, 95%CI: 1.31-5.55) were associated with high trajectories of discretionary foods intake. Conversely, longer duration of breastfeeding (RR 0.99, 95%CI: 0.97-0.99), and timely introduction of complementary foods (RR 0.30, 95%CI: 0.15-0.61) had a protective effect against high discretionary foods consumption in infancy and early childhood. CONCLUSION: Children's frequency of discretionary foods intake increases markedly as they transition from infancy to preschool age, and the trajectories of intake established during early childhood are strongly influenced by socio-demographic factors and infant feeding choices. Hence, there is a need for targeted strategies to improve nutrition in early childhood and ultimately prevent the incidence of chronic diseases in children.

Diet, Nutrition, and Oral Health: What Influences Mother's Decisions on What to Feed Their Young Children?

The purpose of this study was to learn about mothers' experiences with food choices for their pre-school children in underprivileged communities in Greater Western Sydney (GWS). A total of 20 mother-child dyads living in GWS were recruited to a qualitative study from an ongoing birth cohort study. Participants' houses were visited for semi-structured interviews, which were recorded, transcribed verbatim, and analysed thematically. The interviews yielded five main themes: (i) food choices, nutrition, and health; (ii) accessibility and availability of foods (iii) buying time for parents; (iv) child's age and their preference on food choices; (v) conditioning certain behaviours by family and cultural factors. Nutrition literacy, child's preferences, unhealthy food intake by family members, child's demand, advertising and availability of harmful foods, and time constraints were all mentioned as hurdles to mothers making appropriate meal choices for their children. However, some identified facilitators were promoting parents' knowledge, increasing access to health educational materials, upskilling mothers to providing healthier alternatives, regulating the marketing of unhealth foods. Although, the present study identified critical factors that influence mothers' food choices for their young children, making healthy food choices is a complex practice as it is shaped by individual, social and environmental influences.

Economic evaluation of the Midwifery Initiated Oral Health-Dental Service programme in Australia.

OBJECTIVES: To critically evaluate the cost-effectiveness of the Midwifery Initiated Oral Health-Dental Service (MIOH-DS) designed to improve oral health of pregnant Australian women. Previous efficacy and process evaluations of MIOH-DS showed positive outcomes and improvements across various measures. DESIGN AND SETTING: The evaluation used a cost-utility model based on the initial study design of the MIOH-DS trial in Sydney, Australia from the perspective of public healthcare provider for a duration of 3 months to 4 years. PARTICIPANTS: Data were sourced from pregnant women (n=638), midwives (n=17) and dentists (n=3) involved in the MIOH trial and long-term follow-up. COST MEASURES: Data included in analysis were the cost of the time required by midwives and dentists to deliver the intervention and the cost of dental treatment provided. Costs were measured using data on utilisation and unit price of intervention components and obtained from a micro-costing approach. OUTCOME MEASURES: Utility was measured as the number of Disability Adjusted Life Years (DALYs) from health-benefit components of the intervention. Three cost-effectiveness analyses were undertaken using different comparators, thresholds and time scenarios. RESULTS: Compared with current practice, midwives only intervention meets the Australian threshold (A$50 000) of being cost-effective. The midwives and accessible/affordable dentists joint intervention was only 'cost-effective' in 6 months or beyond scenarios. When the midwife only intervention is the comparator, the midwife/dentist programme was 'cost-effective' in all scenarios except at 3 months scenario. CONCLUSIONS: The midwives' only intervention providing oral health education, assessment and referral to existing dental services was cost-effective, and represents a low cost intervention. Midwives' and dentists' combined interventions were cost-effective when the benefits were considered over longer periods. The findings highlight short and long term economic benefits of the programme and support the need for policymakers to consider adding an oral health component into antenatal care Australia wide.

Impact of Dietary Trajectories on Obesity and Dental Caries in Preschool Children: Findings from the Healthy Smiles Healthy Kids Study.

This study examines the impact of longitudinal dietary trajectories on obesity and early childhood caries (ECC) in preschool children in Australia. Mother-infant dyads from the Healthy Smiles Healthy Kids study were interviewed at 4 and 8 months, and 1, 2, and 3 years of age. Children underwent anthropometric and oral health assessments between 3 and 4 years of age. Multivariable logistic regression and negative binomial regression analysis were performed for the prevalence of overweight and obesity, and the number of tooth surfaces with dental caries, respectively. The intake of core, discretionary, and sugary foods showed distinct quadratic (n = 3) trajectories with age. The prevalence of overweight or obesity was 10% (n = 72) and that of early childhood caries (ECC) was 33% (mean decayed, missing, and filled tooth surfaces (dmfs) score: 1.96). Children with the highest trajectories of discretionary foods intake were more likely to be overweight or obese (adjusted OR: 2.51, 95 %CI: 1.16-5.42). Continued breastfeeding beyond 12 months was associated with higher dmfs scores (adjusted IRR: 2.17, 95 %CI: 1.27-3.73). Highest socioeconomic disadvantage was the most significant determinant for overweight or obesity (adjusted OR: 2.86, 95 %CI: 1.11-7.34) and ECC (adjusted IRR: 2.71, 95 %CI: 1.48-4.97). Targeted health promotion interventions should be designed to prevent the incidence of two highly prevalent conditions in preschool children.

How Do Mothers Living in Socially Deprived Communities Perceive Oral Health of Young Children? A Qualitative Study.

This qualitative study aims to explore and gain an in-depth understanding of the knowledge and perceptions of mothers living in Greater Western Sydney (GWS), one of Australia's most socio-economically disadvantaged regions, regarding the factors that influence oral health of young children. Mother-child dyads (n = 45) were purposively selected from a population-based cohort study in GWS. Semi-structured in-depth interviews were audio-recorded, transcribed verbatim, and subsequently analyzed using thematic analysis. Five main themes emerged from the interviews: (1) beliefs about child oral health and first set of teeth; (2) awareness and attitudes towards oral health services; (3) identification of caries risk and protective factors; (4) broader cultural and social class influences on childhood oral health practices; and (5) the influence of parental self-confidence, self-efficacy, and perceived control. Overall, mothers reported having limited knowledge and awareness on the importance of baby teeth, child's first dental visit, and seeking oral health care. Oral health and preventative practices in children were reported to be influenced by past dental experiences, culture and social class, and parental factors. The empirical findings of this study bring our attention to the critical factors that influence child oral health and the opportunities for co-creating child oral health promotion by targeting mothers.

Views of Indian Migrants on Adaptation of Child Oral Health Leaflets: A Qualitative Study.

The aim of this study was to gain insight on the views of Hindi-speaking mothers on readily available English language oral health education materials and to evaluate the acceptability of Hindi language adapted versions of these materials. This qualitative study is nested within an ongoing multi-centre birth cohort study in Greater Western Sydney, Australia. Following purposive selection of Hindi-speaking mothers (n = 19), a semi-structured interview was conducted. Two English leaflets were mailed to participants prior to the interview. The simplified English and translated Hindi versions of the leaflets were provided at the interview, and the participants were asked to compare and evaluate all three versions. Interviews were audio recorded, and thematic analysis was used to analyse data from interview transcripts. A majority of the participants reported a certain degree of difficulty in reading and comprehending oral health messages in Hindi. Although Hindi translations were accurate, mothers preferred the simplified English as opposed to the Hindi version. Visual illustrations and a simple layout facilitated the understanding of oral health messages. Developers of oral health education leaflets should thoroughly research their prospective user groups, particularly migrant populations, and identify the need for simplified or translated oral health education leaflets.

Factors Influencing the Early Introduction of Sugar Sweetened Beverages among Infants: Findings from the HSHK Birth Cohort Study.

Understanding the determinants of early introduction of sugar sweetened beverages (SSBs) may assist in designing effective public health interventions to prevent childhood weight related conditions (obesity). This study explores the relationship between family/infant characteristics and the early introduction of SSBs among infants in Sydney, Australia. Mothers (n = 934) from an ongoing birth cohort study were interviewed at 8, 17, 34, and 52 weeks postpartum. Multivariable logistic regression analysis was used to identify family/infant factors independently associated with the likelihood of early introduction of SSBs (<52 weeks of age). Of the 934 mothers interviewed, 42.7% (n = 399) of infants were introduced to SSBs before 52 weeks. Mothers who were born in Vietnam (adjusted Odds Ratio (AOR) = 2.14; 95% confidence interval (CI) 1.33, 3.47), other Asian countries (AOR = 1.62; 95% CI 1.02, 2.58) as well as single mothers (AOR = 3.72; 95% CI 2.46, 5.62) had higher odds of introducing SSBs early to their infants. Mothers from highly advantaged socioeconomic background (AOR = 0.43; 95% CI 0.28, 0.68), those who breastfed their baby for 17-25 weeks (AOR = 0.60; 95% CI 0.37, 0.99), 26-51 weeks (AOR = 0.65; 95% CI 0.45, 0.94), and 52 weeks or more (AOR = 0.62; 95% CI 0.43, 0.90); and those who introduced solids between 17-25 weeks (AOR = 0.58; 95% CI 0.36, 0.91) and 26 weeks or more (AOR = 0.55; 95% CI 0.34, 0.91) had reduced odds of introducing SSBs early. Tailoring health promotion programs for these vulnerable groups may delay the introduction of SSBs.

Determinants of Full Breastfeeding at 6 Months and Any Breastfeeding at 12 and 24 Months among Women in Sydney: Findings from the HSHK Birth Cohort Study.

The aim of this study was to report on breastfeeding duration up to 24 months and determine the predictors of breastfeeding duration among women in South Western Sydney, one of the most culturally diverse and socioeconomically disadvantaged regions of New South Wales (NSW), Australia. Mother-infant dyads (n = 1035) were recruited to the Healthy Smiles Healthy Kids birth cohort study. Study data were collected through telephone interviews at 2, 4, 8, 12, and 24 months postpartum. Cox proportional hazards models were used to determine factors associated with the risk of stopping full breastfeeding at six months and any breastfeeding at 12 and 24 months. The majority of mothers (92.3%) had initiated breastfeeding. At six months, 13.5% of infants were fully breastfed, while 49.9% received some breast milk. Only 25.5% and 2.9% of infants received some breast milk at 12 and 24 months, respectively. Lower maternal education level, lower socioeconomic status, full-time employment, maternal smoking during pregnancy, and caesarean delivery were associated with increased risk of stopping full breastfeeding at six months and any breastfeeding at 12 and 24 months. Older maternal age and partner's preference for breastfeeding were associated with an increased likelihood of continuing any breastfeeding at 12 and 24 months. These findings present a number of opportunities for prolonging breastfeeding duration in disadvantaged communities in NSW.

Determinants for early introduction of complementary foods in Australian infants: findings from the HSHK birth cohort study.

OBJECTIVE: The purpose of this study was to examine the timing of introduction of complementary (solid) foods among infants in South Western Sydney, Australia, and describe the maternal and infant characteristics associated with very early introduction of solids. METHODS: Mother-infant dyads (n = 1035) were recruited into the "Healthy Smiles Healthy Kids" study by Child and Family Health Nurses at the first post-natal home visit. Data collected via telephone interviews at 8, 17, 34 and 52 weeks postpartum included timing of introduction of solids and a variety of maternal and infant characteristics (n = 934). Multiple logistic regression was used to identify factors independently associated with the risk of introducing solids very early, which for the purpose of this study was defined as being before 17 weeks. RESULTS: The median age of introduction of solids was 22 weeks. In total, 13.6% (n = 127) of infants had received solids before 17 weeks and 76.9% (n = 719) before 26 weeks of age. The practice of introducing solids early decreased with older age of the mother. Compared to women < 25 years of age, those who were 35 years or older were 72% less likely to introduce solids very early (OR = 0.28, CI95 0.14-0.58). Single mothers had more than twice the odds of introducing solids before the age of 17 weeks compared to married women (OR = 2.35, CI95 1.33-4.16). Women who had returned to work between 6 to 12 months postpartum were 46% less likely to introduce solids very early compared with those who were not working at the child's first birthday (OR = 0.54, CI95 0.30-0.97). Women born in Vietnam and Indian sub-continent had lower odds of introducing solids very early compared to Australian born women (OR = 0.42, CI95 0.21-0.84 and OR = 0.30, CI95 0.12-0.79, respectively). Infants who were exclusively formula-fed at 4 weeks postpartum had more than twice the odds of receiving solids very early (OR = 2.34, CI95 1.49-3.66). CONCLUSIONS: Women who are younger, single mothers, those not working by the time of child's first birthday, those born in Australia, and those who exclusively formula-feed their babies at 4 weeks postpartum should be targeted for health promotion programs that aim to delay the introduction of solids in infants to the recommended time.

Predictors of Early Introduction of Core and Discretionary Foods in Australian Infants-Results from HSHK Birth Cohort Study.

Early introduction of complementary foods can have a detrimental impact on children's long-term health. This study examined the timing and determinants of early introduction of core and discretionary foods among infants in Sydney, Australia. Mothers (n = 1035) from an ongoing population-based birth cohort study were interviewed at 8, 17, 34 and 52 weeks postpartum. The outcome was 'age at which particular core and discretionary food items were first introduced'. Multivariable logistic regression models were used to investigate family and infant-related determinants of early introduction of core (<17 weeks of age) and discretionary foods (<52 weeks of age). Of the 934 mother-infant dyads interviewed, 12% (n = 113) of infants were introduced core foods before 17 weeks of age (median: 22). Mothers working part-time (adjusted odds ratio (OR): 3.42, 95% confidence interval (CI): 1.54-7.62) and those exclusively formula-feeding their babies at four-weeks postpartum (adjusted OR 3.26, 95% CI: 1.99-5.33) were most likely to introduce core foods early. Ninety-five percent (n = 858) of infants were introduced discretionary foods before 52 weeks of age (median: 28). Low socio-economic status was significantly associated with early introduction of discretionary foods (adjusted OR: 3.72, 95% CI: 1.17-11.78). Compliance with infant feeding guidelines related to core foods was better; however, discretionary foods were introduced early in most infants.

Exploring nursing and allied health perspectives of quality oral care after stroke: A qualitative study.

BACKGROUND: Maintaining good oral health remains a challenge among those hospitalised after stroke. Stroke nurses and allied health clinicians have a potential role in providing oral care, but no studies in Australia to date have explored their perceptions and needs. AIMS: To explore the perspectives of nursing and allied health stroke clinicians regarding oral care for stroke patients across acute care and stroke rehabilitation settings. METHODS: This study followed an exploratory qualitative design, using a constructivist approach. Participants from two metropolitan public hospitals were purposively recruited to participate in focus groups. Data was thematically analysed. RESULTS: Twenty-one clinicians participated. Clinicians' knowledge and practices relating to oral healthcare for stroke patients were inadequate. Most staff felt they did not have adequate knowledge, resources and training to administer oral care in this setting and proposed enhancing education of stroke clinicians, patients and informal caregivers, as well as improving quality point of care resources. There was overall support for the integrated dental care after stroke model of care. DISCUSSION: This study revealed many gaps in current care and highlighted areas for improvement. Patients and their caregivers needed to be actively engaged as partners to improve oral healthcare within acute and rehabilitation stroke settings. CONCLUSION: This study provided insight into nurses' and allied health stroke clinicians' current knowledge and practices of oral care in various stroke settings. The findings from this study will inform development of a model of care to train stroke nurses in providing oral care.

The role of oral health care professionals in preventing and managing obesity: A systematic review of current practices and perceived barriers.

INTRODUCTION: There is a growing interest to expand the role of oral health care professionals in obesity prevention and management. The aim of this systematic review was to synthesise the evidence on current practices of, and perceived barriers to, oral health care professionals' involvement in obesity screening and management. METHODS: Key search strings were developed and used in seven databases from inception through February 6, 2019. Data were screened against inclusion criteria, independently extracted, and quality appraised by two reviewers based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS: Ten studies were included in this review. The practices of oral health care professionals in relation to obesity assessment, counseling, and specialist referrals were found to be very limited. Oral health care professionals believed in their role to support patients for achieving weight-loss goals, however just over one-third were trained in anthropometry. Perceived barriers included lack of time, limited knowledge or training, patients' unwillingness to listen to oral health care professionals' advice, and lack of appropriate specialist referrals. CONCLUSION: Oral health care professionals are well-positioned and supportive in undertaking healthy weight interventions in their clinical practice; however, their practices are limited due to barriers such as lack of time, limited training and lack of referrals.

The oral health status, behaviours and knowledge of patients with cardiovascular disease in Sydney Australia: a cross-sectional survey.

BACKGROUND: Periodontal disease is a risk factor for atherosclerotic cardiovascular disease and it is recommended internationally that patients with cardiovascular disease should engage in preventative oral health practices and attend regular dental care visits. This study aimed to explore the oral health status, behaviours and knowledge of patients with cardiovascular disease. METHODS: A cross-sectional questionnaire containing 31 items was administered to patients with cardiovascular disease from cardiac rehabilitation and outpatient clinics in Sydney Australia in 2016-2017. RESULTS: Of the 318 patients surveyed, 81.1% reported having at least one oral health problem. Over a third (41.2%) of participants had not seen a dentist in the preceding 12 months and 10.7% had received any oral healthcare information in the cardiac setting. Those with valvular conditions were more likely to have received information compared to those with other cardiovascular conditions (40.6% versus 7.4%, p < 0.001). Only half of the participants had adequate oral health knowledge. CONCLUSIONS: Despite a high incidence of reported oral health problems, many patients lacked knowledge about oral health, were not receiving oral health information from cardiac care providers and had difficulty accessing dental services. Further research is needed to develop oral health strategies in this area.

Process evaluation of the midwifery initiated oral health-dental service program: Perceptions of midwives in Greater Western Sydney, Australia.

BACKGROUND: Despite links between poor maternal oral health, adverse pregnancy outcomes and early childhood decay there is limited emphasis on maternal oral health in Australia. To address this, the Midwifery Initiated Oral Health Dental Service (MIOH-DS) program was developed in collaboration with the Australian College of Midwives. AIMS: To undertake a process evaluation and explore perceptions of midwives involved in the MIOH-DS program to determine its practicability, acceptability and feasibility if it were to be up-scaled and implemented into clinical practice. METHODS: Qualitative content analysis was undertaken on data from three focus groups with 21 midwives. FINDINGS: Midwives generally found the MIOH-DS to be acceptable and feasible with potential for widespread scalability. The trust women had in midwives was an important factor in gaining women's attention about oral health in pregnancy. The program assisted in increasing midwives' knowledge and awareness, though some felt it was outside their scope of practice. The oral health assessment tool was acceptable to midwives but some concerns were expressed about undertaking a visual oral inspection. Most midwives stated they were now confident with referring individuals to a dentist. Significant barriers to widespread implementation included the cost of dental care and the continued lack of awareness and misconceptions pregnant women had towards oral health. CONCLUSION: Midwives found the MIOH-DS to be acceptable and feasible which are two important barriers to potential implementation at scale. Misconceptions over the importance of oral health by women and cost of accessing dental services still need resolving.

Process evaluation of the midwifery initiated oral health-dental service program: Perceptions of dental professionals.

ISSUE ADDRESSED: All pregnant women should have a comprehensive oral health evaluation. Unfortunately, many pregnant women seldom seek dental care and some dentists are hesitant to treat during pregnancy. To address these issues, the Midwifery Initiated Oral Health Dental Service (MIOH-DS) program was developed in Australia. The aim of this study was to undertake a process evaluation and explore the perceptions of dental professionals involved in the program to determine the acceptability, feasibility and effectiveness of the program if it were to be upscaled. METHODS: A qualitative approach using content analysis was conducted on data from two focus groups involving 12 dental professionals. RESULTS: All participants were supportive of the MIOH-DS program. They thought pregnant women were receptive to their care, and reported markedly improved oral health. The provision of free dental care and the involvement of midwives were cited as major factors that improved the uptake of the program. Some of the challenges encountered were the prevailing misconceptions about the safety of dental treatment and pregnancy-related impairments. CONCLUSIONS: Dental professionals found the MIOH-DS to be acceptable, feasible and effective in improving oral health of pregnant women and their uptake of dental services. However, some challenges need to be addressed as the MIOH-DS program is upscaled into a cost-effective model. SO WHAT?: Dental professionals are important stakeholders in the MIOH-DS model. The process evaluation of the successful dental intervention is necessary to understand how and why such interventions work, and is an important step in scaling up to a population-wide intervention.

A content analysis of Australian television advertising: focus on child and adolescent oral health.

BACKGROUND: Children's preferences for cariogenic foods and/or drinks has been proven to be associated with exposure to advertisements. This study aimed to assess and compare the proportion of cariogenic food and /or drink advertisements aired on three metropolitan Sydney commercial television channels at different broadcast times during school term and school holidays. METHODS: Three Sydney free-to-air television channels (Channels Seven, Nine, and Ten) were recorded between June 2016 and January 2017. Two weekdays and one weekend day were recorded for a week for each channel during the school term and school holidays, respectively. All channels were recorded from 0630 h until 2300 h. Food and/or drink advertisements were categorised according to the time they were aired and their sugar and acid content. For each channel, school holiday data was compared with school term data. Pearson chi-squared testing was used to determine the difference in advertisements rates across TV channels and broadcast times including school holidays and school term. RESULTS: The proportion of food and/or drink advertisements for all networks was less than 10% of all advertisements. Overall, Channel Ten had the most food and/or drink advertisements (39.74%) and Channel Seven had the lowest (28.60%). Channel Ten aired the largest proportion of food and/or drink advertisements (27.18%) during school term Channel Nine aired the highest number of food and/or drink adverts (15.50%) during school holidays. There were more food and/or drink advertisements during children's viewing hours compared to overlap, adult, and other viewing periods respectively, with Channel Ten airing the highest advertisements (15.72%) and Channel Seven airing the least (11.35%) food and/or drink advertisements. For all analyses, Pearson chi-square tests had a p-value < 0.001. CONCLUSION: Although the overall proportion of food and/or drink advertisements aired on Sydney television is low, the advertisements containing high sugar and /or acid were broadcasted more during children's viewing times than other times and during school term compared to school holidays.

Evaluation of a midwifery initiated oral health-dental service program to improve oral health and birth outcomes for pregnant women: A multi-centre randomised controlled trial.

BACKGROUND: Oral health care during pregnancy is important for the health of the mother and child. However, pregnant women have limited knowledge about maternal oral health and seldom seek dental care. Further, due to limited training antenatal care providers like midwives rarely discuss oral health with pregnant women. The Midwifery-Initiated Oral Health Dental Service program was developed to address current gaps in oral promotional interventions during pregnancy. OBJECTIVES: To assess the effectiveness of a Midwifery-Initiated Oral Health Dental Service program in improving uptake of dental services, oral health knowledge, quality of oral health, oral health status and birth outcomes of pregnant women. DESIGN: Multi-centre randomised controlled trial. SETTING: Three large metropolitan public hospitals in Sydney, Australia. PARTICIPANTS: Pregnant women attending their first antenatal appointment who were at least 18 years old and had a single low risk pregnancy between 12 and 20 weeks gestation. METHODS: 638 pregnant women were allocated to three groups using block randomisation (n = 211) control group, intervention group 1 (n = 215), intervention group 2 (n = 212) and followed up till birth. Study investigators and data collectors were blinded to group allocation. Intervention group 1 received a midwifery intervention from trained midwives involving oral health education, screening and referrals to existing dental pathways. Intervention group 2 received the midwifery intervention and a dental intervention involving assessment/treatment from cost free local dental services. The control group received oral health information at recruitment. Primary outcome was uptake of dental services. Secondary outcomes included oral health knowledge, quality of oral health, oral health status and birth outcomes. RESULTS: Substantial improvements in the use of dental services (20.2% Control Group; 28.3% Intervention group 1; 87.2% Intervention group 2; Odds Ratio Intervention group 2 vs Control Group = 29.72, 95% CI 15.02-58.53, p < 0.001), women's oral health knowledge (p = 0.03); quality of oral health (p < 0.001) and oral health outcomes (sulcus bleeding, dental plaque, clinical attachment loss, decayed/filled teeth- p < 0.001) were found in Intervention group 2. No difference in the rate of preterm or low-birth weight was found. CONCLUSIONS: The Midwifery-Initiated Oral Health Dental Service program (Intervention group 2) improved the uptake of dental services and oral health of pregnant women and is recommended during antenatal care. A cause and effect relationship between this intervention and improved birth outcomes was not supported.

Lessons learnt in recruiting disadvantaged families to a birth cohort study.

BACKGROUND: Dental decay in early childhood can be prevented by a model based on shared care utilising members of primary care team such as Child and Family Health Nurses (CFHNs) in health promotion and early intervention. The aims of this study were to identify the facilitators and barriers faced by CFHNs in recruiting research participants from disadvantaged backgrounds to a birth cohort study in South Western Sydney, Australia. METHODS: Child and Family Health Nurses recruited mothers-infants dyads (n = 1036) at the first post-natal home visit as part of Healthy Smiles Healthy Kids Study, an ongoing birth cohort study in South Western Sydney. The nurses (n = 19) were purposively selected and approached for a phone based in-depth semi-structured interview to identify the challenges faced by them during the recruitment process. Interviews were audio-recorded, subsequently transcribed verbatim and analysed by thematic analysis. RESULTS: The nurses found the early phase of parenting was an overwhelming stage for parents as they are pre-occupied with more immediate issues such as settling and feeding a newborn. They highlighted some key time-points such as during pregnancy and/or around the time of infant teething may be more appropriate for recruiting families to dental research projects.
