'Everything's adaptable': A qualitative study of how nurses make decisions in sustained home-visiting care with mothers and children experiencing adversity.

AIMS: To explore nurse decision-making processes in the delivery of sustained home-visiting care for mothers of young children who are experiencing adversity. DESIGN: Qualitative descriptive research design using focus group interviews. METHODS: Thirty-two home-visiting nurses participated in four focus group interviews exploring their decision-making in the care they provide to families. The data were analysed using a reflexive thematic analysis approach. RESULTS: Four steps of a recurring stepwise decision-making process were identified: (1) information gathering; (2) exploring; (3) implementing; (4) checking. The facilitators and barriers to effective decision-making processes were also identified and included elements relating to good relationship skills, a good attitude, high quality training and mentoring and resources. CONCLUSION: The findings indicate that a recurring stepwise process of decision-making requires both analytical and intuitive approaches. The intuition required by home-visiting nurses is to sense unvoiced client needs and identify the right time and way to intervene. The nurses were engaged in adapting the care in response to the client's unique needs while ensuring the fidelity of the programme scope and standards. We recommend creating an enabling working environment with cross-disciplinary team members and having well-developed structures, particularly the feedback systems such as clinical supervision and case reviews. Enhanced skills to establish trusting relationships with clients can help home-visiting nurses make effective decisions with mothers and families, particularly in the face of significant risk. IMPACT: This study explored nurse decision-making processes in the context of sustained home-visiting care, which has been largely unexplored in the research literature. Understanding the effective decision-making processes, particularly when nurses customize or individualize the care in response to the client's unique needs, assists with the development of strategies for precision home-visiting care. The identification of facilitators and barriers informs approaches designed to support nurses in effective decision-making.

Breastfeeding after return to work: An Australian national workplace survey.

Breastfeeding initiation rates in Australia are high but duration rates fall well below the World Health Organization targets. Return to work is a known factor impacting 6 months exclusive breastfeeding and continuation into the infants second year of life. Work related factors can influence a woman's confidence in maintaining breastmilk supply after return to employment and determine whether she meets her personal breastfeeding goals. This cross-sectional online survey is the first Australian study to explore women's experience of maintaining breastfeeding after return to work, in all work sectors. Results revealed variations across work sectors reflected in worker autonomy and confidence in speaking up about breastfeeding rights. Women who had autonomy or flexibility in planning their workday were more likely to be confident in maintaining breastmilk supply. The main predictors for milk supply confidence and meeting personal breastfeeding goals included having: a suitable place to express milk; confidence in speaking out about rights; a formal return-to-work plan; a supportive workplace; and returning to work after the period of exclusive breastfeeding. This study reveals that supportive workplace environments can lead to increased confidence in maintaining milk supply, extending durations of breastfeeding. Women who are confident in their rights to express breastmilk, or breastfeed at work, are more likely to meet their own breastfeeding goals. Education, and awareness raising, on the rights of breastfeeding women in the workplace, is a gender equity imperative that can improve experiences for breastfeeding women, and, increase manager and co-worker knowledge for creating enabling workplace environments for breastfeeding employees.

Does customised care improve satisfaction and positively enable parents in sustained home visiting for mothers and children experiencing adversity?

BACKGROUND: The Maternal Early Childhood Sustained Home-visiting program (MECSH) is a structured nurse-delivered program designed to address health inequities experienced by families experiencing significant adversity. There is strong evidence for the effectiveness of this program, but limited research exploring the practice and process elements that are core to positive parent outcomes. This study aimed to examine the relationship between customised care related to the mother's risk factors and parent satisfaction and enablement in the delivery of a MECSH-based program. METHODS: A cross-sectional study design was used. Program delivery data collected as part of a large randomised controlled trial of a MECSH-based sustained nurse home visiting program in Australia (right@home) were analysed. This study used the data collected from the intervention arm in the trial (n = 352 women). Parent satisfaction was measured at child age 24 months using the modified short-form Patient Satisfaction Questionnaire. Parent enablement was measured at child age 24 months by a modified Parent Enablement Index. Customised care was defined as appropriate provision of care content in response to four maternal risks: smoking, mental health, domestic violence and alcohol and drugs. Logistic analysis was performed to assess the impact of customised care on parent satisfaction and enablement while adjusting for covariates such as sociodemographic factors. A significance level of 95% was applied for analysis. RESULTS: Our results indicated high levels of satisfaction with the care provided and positive enablement. There were several sociodemographic factors associated with satisfaction and enablement, such as language spoken at home and employment experience. The mothers who received customised care in response to mental health risk and domestic violence had significantly greater satisfaction with the care provided and experienced an increase in enablement compared to those who did not receive such care. CONCLUSION: This study contributes to the existing body of empirical research that examines the relationship between care processes and client outcomes in the delivery of home visiting services. It is essential for the sustained nurse home visiting service model to be flexible enough to cater for variations according to family circumstances and needs while maintaining a core of evidence-based practice.

Identification of families in need of support: Correlates of adverse childhood experiences in the right@home sustained nurse home visiting program.

BACKGROUND: Little is known about the efficacy of pregnancy screening tools using non-sensitive sociodemographic questions to identify the possible presence of as yet undiagnosed disease in individuals and later adverse childhood events disclosure. OBJECTIVES: The study aims were to: 1) record the prevalence of risk disclosed by families during receipt of a sustained nurse home visiting program; and 2) explore patterns of relationships between the disclosed risks for their child having adverse experiences and the antenatal screening tool, which used non-sensitive demographic questions. DESIGN: Retrospective, observational study. PARTICIPANTS AND METHODS: Data about the participants in the intervention arm of the Australian right@home trial, which is scaffolded on the Maternal Early Childhood Sustained Home-visiting model, collected between 2013 and 2017 were used. Screening data from the 10-item antenatal survey of non-sensitive demographic risk factors and disclosed risks recorded by the nurse in audited case files during the subsequent 2 year intervention were examined (n = 348). Prevalence of disclosed risks for their child having adverse experiences were analysed in 2019 using multiple response frequencies. Phi correlations were conducted to test associations between screening factors and disclosed risks. RESULTS: Among the 348 intervention participants whose files were audited, 300 were noted by nurses to have disclosed risks during the intervention, with an average of four disclosures. The most prevalent maternal disclosures were depression or anxiety (57.8%). Mental health issues were the most prevalent partner and family disclosures. Screening tool questions on maternal smoking in pregnancy, not living with another adult, poverty and self-reporting anxious mood were significantly associated with a number of disclosed risks for their child having adverse experiences. CONCLUSIONS: These findings suggest that a non-sensitive sociodemographic screening tool may help to identify families at higher risk for adverse childhood experiences for whom support from a sustained nurse home visiting program may be beneficial.

Variations in sustained home visiting care for mothers and children experiencing adversity.

OBJECTIVE: This study aimed to examine the variations in care received by mothers and families within a sustained home visiting program. We sought to identify the extent to which there were variations in home visiting care in response to the program schedule and families' risk factors. DESIGN AND SAMPLE: Data collected within the right@home program, a randomized controlled trial (RCT) for a sustained nurse home visiting intervention in Australia, were analyzed. A total of 352 women comprised the intervention arm of the trial. MEASUREMENTS: Visit content in the home visiting program, sociodemographic data, and families' risk factors were used for analysis. RESULTS: Our results confirmed that the majority of women received scheduled content on time or within an acceptable timeframe, except for the sleeping program. Women with identified risks were significantly more likely to receive content related to those risks than women without those risks (smoking: Odds Ratio [OR] = 15.39 [95%CI 3.7-64.7], mental health: OR = 15.04 [1.8-124.0], domestic violence: OR = 4.07 [2.0-8.3], and drugs and alcohol: OR = 1.81 [1.1-3.0]). CONCLUSIONS: The right@home program had high compliance with the scheduled content. Capacity development in responding to mothers with the risk of domestic violence and drugs and alcohol is recommended. Further research is required to explore the relationship between variations in care and critical outcomes.

Australian foster carers' views of supporting maternal breastfeeding and attachment in out-of-home care.

BACKGROUND: Breastfeeding supports infant health, growth and development, and promotes maternal attachment and sensitive caregiving. Maternal separation due to child protection concerns can result in termination of breastfeeding with associated adverse outcomes. How to preserve breastfeeding when infants are placed in out-of-home care is an issue of concern. OBJECTIVE: To consider the views of foster carers towards provision of breastmilk and breastfeeding for infants in their care. PARTICIPANTS AND SETTING: Foster carers (including kinship carers), in Australia, who had cared for at least one infant in the years 2013-2018 completed an online survey. METHODS: Foster carer's views were collected via an online survey and subjected to content analysis. RESULTS: Respondents (n = 184) expressed mixed views about; mothers breastfeeding during contact visits, increased frequency of contact visits for breastfeeding; and the provision of expressed breastmilk to infants in their care. Concerns were raised about the safety of breastmilk from mothers abusing substances and the value of breastfeeding if reunification was not possible. Because of these concerns, some carers discarded expressed breastmilk and resisted frequent contact. Conversely, breastfeeding was also viewed positively as a way for mothers to maintain attachment with their infants, where reunification of the mother-infant dyad was the goal. CONCLUSIONS: This study highlights foster carers' view of breastfeeding as a facilitator of attachment between mothers and their infants. While fosters carers were largely supportive of breastfeeding as a way to improve infant health and facilitate mother-infant attachment, they held concerns regarding the safety of breastmilk supplied to them.

Australian Foster Carers' Views and Concerns Regarding Maternal Drug Use and the Safety of Breastmilk.

Parental substance misuse and mental health issues are major factors associated with infant placement into out-of-home care. Such placements may result in disruption and/or cessation of breastfeeding. Provision of breastmilk to infants in out-of-home care (OOHC) is desirable in terms of infant health and development, and also in supporting maternal caregiving. However, little is known about how breastfeeding is supported for infants in out-of-home care. This study used an online survey to explore the facilitation of breastfeeding in the context of OOHC and foster carers' management of expressed breastmilk (EBM). Foster carers were generally open to the idea of maternal breastfeeding and infants in their care receiving EBM from their mothers. However, the majority of respondents expressed concern regarding the safety of EBM for infant consumption due to the possibility of harmful substances in the milk. Concerns regarding the safety of handling EBM were also prevalent. These concerns caused foster carers to discard EBM. Findings suggest foster carers' may lack knowledge related to maternal substance use and breastmilk. Better integration between health care and social service systems, where the voices of mothers, foster carers and child protection workers are heard, is necessary to develop solutions enabling infants living in OOHC access to their mother's breastmilk.

"Paper, face-to-face and on my mobile please": A survey of women's preferred methods of receiving antenatal education.

BACKGROUND: Antenatal education prepares women for childbirth and can be delivered face-to-face, in hard-copy and electronically. Smartphones allow access to online learning and internet searching is common among pregnant women. It is unclear which mode of health information delivery women prefer. AIM: This study aimed to investigate how women at one Local Health District (LHD) preferred to receive health information during pregnancy and the early postnatal period. METHODS: We developed a survey to gather data on women's preferences for educational information. Women who were discharged from one LHD, in NSW Australia, were invited, in 2019, to participate in a simple 14 question survey, either online or in hard copy format. FINDINGS: In total, 685 women completed the survey which represented a 40% response rate over a period of two months. The survey revealed women commonly used smart phones, or other devices, to source information. Despite this, most women preferred to receive antenatal education via non-electronic methods. Of note many participants felt underprepared for the post-birth period. The method of survey completion, whether hardcopy or online, aligned with individuals' preferences for information delivery. CONCLUSION: Non-electronic methods of education delivery were the preferred method for most women, and this was consistent across all educational, cultural and socioeconomic levels. Women sought information online, or through apps, but these options did not always meet their knowledge needs, especially regarding the postnatal period. We recommend that hospitals continue to provide information in a variety of modes, as exclusively electronic methods may marginalise groups of women.

Associations between rapid weight gain in infancy and weight status among urban Aboriginal children participating in the Gudaga study: nine-year results from a cohort study.

BACKGROUND: Rapid weight gain (RWG) in infants is associated with overweight and obesity in childhood and beyond, highlighting the need for early intervention. METHODS: Data from a birth cohort of Australian Aboriginal and Torres Strait Islander children living in an urban area were analysed to determine the prevalence of RWG in infancy and the association between RWG and overweight and obesity, categorised using both body mass index and waist to height ratio from birth to 9 years. RESULTS: The prevalence of overweight and obesity is higher in this cohort (at 47%) than the population average. The Australian population as a whole has seen steady increases. In this cohort although the prevalence of combined overweight and obesity remained relatively stable between 2 and 9 years, the proportion of children categorized as obese using BMI has increased. 42% of children who were overweight or obese at 9 years had experienced RWG in infancy. Children were 2.7 and 3.9 times more likely to be overweight at 9 years if they experienced RWG or were overweight at 2 years, respectively. CONCLUSION: RWG was common in this cohort and the strongest predictor of excess weight at 2 years and at 9 years. Early intervention is crucial in the first year of life across the whole population to prevent obesity in children. Culturally appropriate interventions developed with the community are required for Aboriginal and Torres Strait Islander babies and their parents.

Effectiveness of the Volunteer Family Connect Program in Reducing Isolation of Vulnerable Families and Supporting Their Parenting: Randomized Controlled Trial With Intention-To-Treat Analysis of Primary Outcome Variables.

BACKGROUND: Volunteer home visiting is a widely adopted community-based approach to support families by linking isolated or vulnerable families with community volunteers who visit their homes weekly over approximately 12 months. This study seeks to robustly evaluate the effectiveness of this model of support for families with young children. OBJECTIVE: This paper reports the intention-to-treat analysis of primary and secondary outcomes for a pragmatic randomized controlled trial (RCT) of the Volunteer Family Connect intervention, a volunteer home-visiting program designed to support families with young children who experience social isolation or a lack of parenting confidence and skills. METHODS: The RCT was conducted across seven sites in Australia. Overall, 341 families were recruited: 169 intervention (services as usual+volunteer home visits) and 172 control (services as usual) families. Intervention families received the program for 3-12 months. Participants were invited to complete six data collection points over a 15-month period. Primary outcomes were community connectedness and parenting competence. Secondary outcomes included parent physical and mental health, general parent wellbeing, parent empowerment, the sustainability of family routines, and the parent-child relationship. According to the protocol, the program would be judged to be effective if at least one of the primary outcomes was significantly positive and the other was neutral (ie, intervention families did not demonstrate positive or negative outcomes compared to the control group). RESULTS: The intervention group demonstrated significant improvement in the primary outcome variable parenting sense of competence as compared to the control group. Overall, there was no significant difference between the intervention and control groups with regard to the primary outcome variable community connectedness, other than on the "Guidance" subscale of the Social Provisions Scale. Because there were statistically significant findings for the total score of one primary outcome variable "parenting sense of competence" and largely neutral findings for the primary outcome variable "community connectedness," the program met the previously defined criteria for program effectiveness. In relation to secondary outcomes, intervention families reported significantly higher wellbeing and were significantly more likely to feel that life was improving. CONCLUSIONS: The Volunteer Family Connect intervention was considered an effective intervention, with a role to play on the landscape of services available to support vulnerable families with young children.

Quality of delivery of "right@home": Implementation evaluation of an Australian sustained nurse home visiting intervention to improve parenting and the home learning environment.

BACKGROUND: Home visiting programs are implemented in high income countries to improve outcomes for families with young children. Significant resources are invested in such programs and high quality evaluations are important. In the context of research trials, implementation quality is often poorly reported and, when reported, is variable. This paper presents the quality of implementation of the right@home program, a sustained nurse home visiting intervention trialled in Australia, and delivered in a 'real world' context through usual child and family health services. right@home is structured around the core Maternal Early Childhood Sustained Home-visiting (MECSH) program, which is a salutogenic, child focused prevention model. METHOD: At each visit right@home practitioners completed a checklist detailing the client unique identifier, date of contact and activities undertaken. These checklists were collated to provide data on intervention dose, retention to program completion at child age 2 years, and visit content, which were compared with the program schedule. Quality of family-provider relationship was measured using the Session Rating Scale. Exploratory factor analysis was conducted to identify clusters of activities and allow qualitative assessment of concordance between program aims and program delivery. RESULTS: Of 363 intervention families offered the program, 352 (97·0%) commenced the program and 304 (87·3%) completed the program to child age 2 years. 253 of 352 (71·9%) families who commenced the program received more than 75 percent of scheduled visits including at least one antenatal visit. Families rated the participant-practitioner relationship highly (mean 39.4/40). The factor analysis identified six antenatal and six postnatal components which were concordant with the program aims. CONCLUSIONS: The right@home program was delivered with higher adherence to program dose, schedule and content, and retention than usually reported in other home visiting research. Program compliance may have resulted from program design (visit schedule, dose, content and delivery flexibility) that was consistent with family aims.

Which frailty scale for patients admitted via Emergency Department? A cohort study.

OBJECTIVES: To determine the prevalence of frailty in Emergency Departments (EDs); examine the ability of frailty to predict poor outcomes post-discharge; and identify the most appropriate instrument for routine ED use. METHODS: In this prospective study we simultaneously assessed adults 65+yrs admitted and/or spent one night in the ED using Fried, the Clinical Frailty Scale (CFS), and SUHB (Stable, Unstable, Help to walk, Bedbound) scales in four Australian EDs for rapid recognition of frailty between June 2015 and March 2016. RESULTS: 899 adults with complete follow-up data (mean (SD) age 80.0 (8.3) years; female 51.4%) were screened for frailty. Although different scales yielded vastly different frailty prevalence (SUHB 9.7%, Fried 30.4%, CFS 43.7%), predictive discrimination of poor discharge outcomes (death, poor self-reported health/quality of life, need for community services post-discharge, or reattendance to ED after the index hospitalization) for all identical final models was equivalent across all scales (AUROC 0.735 for Fried, 0.730 for CFS and 0.720 for SUHB). CONCLUSION: This study confirms that screening for frailty in older ED patients can inform prognosis and target discharge planning including community services required. The CFS was as accurate as the Fried and SUHB in predicting poor outcomes, but more practical for use in busy clinical environments with lower level of disruption. Given the limitations of objectively measuring frailty parameters, self-report and clinical judgment can reliably substitute the assessment in EDs. We propose that in a busy ED environment, frailty scores could be used as a red flag for poor follow-up outcome.

Community Volunteer Support for Families With Young Children: Protocol for the Volunteer Family Connect Randomized Controlled Trial.

BACKGROUND: Use of community volunteers to support vulnerable families is a widely employed strategy with a long history. However, there has been minimal formal scientific investigation into the effectiveness of volunteer home visiting programs for families. There is also a need for research examining whether volunteer home visiting leads to improved outcomes for volunteers. OBJECTIVE: The objective of this paper is to describe the research protocol for a pragmatic randomized controlled trial (RCT) of the Volunteer Family Connect intervention, a volunteer home visiting program designed to support families of young children who experience social isolation or a lack of parenting confidence and skills. The project is being conducted in partnership with 3 leading not-for-profit organizations, designed to contribute to the body of evidence that informs decisions about appropriate family support services according to the level of need. It is the first study to examine outcomes for both the families and the volunteers who deliver the service. METHODS: The RCT is being conducted in 7 sites across Australia. We aim to recruit 300 families to the study: 150 control (services as usual) and 150 intervention (services as usual + volunteer home visiting) families. Intervention families will receive the service for 3-12 months according to their needs, and all participants will complete 6 data collection points over 15 months. A minimum of 80 volunteers will also be recruited, along with a matched community comparison group. The volunteers will complete 3 data collection points over 12 months. Primary outcomes include community connectedness and parenting competence. Secondary outcomes include parent physical and mental health; general parent well-being; parent empowerment; the child-parent relationship; sustainability of family routines; child immunization; child nutrition or breastfeeding; number of accidental injury reports; and volunteer health, well-being, and community connectedness. RESULTS: This effectiveness trial was funded in 2016, and we aim to complete data collection by the end of 2018. The first results are expected to be submitted early in 2019. CONCLUSIONS: There is a need to rigorously assess volunteer home visiting and whether it has a unique and important role on the service landscape, complementary to professional services. This research is the first trial of a volunteer home visiting program to be conducted in Australia and one of the largest of its kind worldwide.

The oral health behaviours and fluid consumption practices of young urban Aboriginal preschool children in south-western Sydney, New South Wales, Australia.

ISSUE ADDRESSED: Australian Aboriginal children have a higher risk of dental caries yet there is limited focus on oral health risk factors for urban Aboriginal preschool children. This study examined the oral health behaviours and fluid consumption practices of young children from an urban Aboriginal community in south-western Sydney, Australia. METHODS: In total, 157 Aboriginal children who were recruited to the "Gudaga" longitudinal birth cohort participated in this study. A survey design was employed and parents responded to the oral health questions when their child was between 18 and 60 months. RESULTS: Few parents (20%) were concerned about their child's oral health across the time period. By 60 months, only 20% of children had seen a dentist while 80% were brushing their teeth at least once daily. High levels of bottle use were seen up to 30 months. Consumption of sugary drinks was also very high in the early years, although this was replaced by water by 36 months. CONCLUSIONS: While there are some encouraging findings, such as the rates of tooth brushing and increasing rates of water consumption, the findings do highlight the poor uptake of dental services and high levels of bottle usage among urban aboriginal children during their early years. SO WHAT?: Targeted oral health promotional programs are needed in the urban Aboriginal community to better support parents understanding of good oral health practices in the early years and engagement with dental health services.

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.

Measuring oral health during pregnancy: sensitivity and specificity of a maternal oral screening (MOS) tool.

BACKGROUND: Midwives can play a key role in promoting the oral health of pregnant women and assessing their oral health status. A maternal oral assessment tool (MOS) was developed and pilot tested by the study investigators to assist midwives in this role and the results were promising. The aim of this study was to undertake further sensitivity and specificity assessment of the MOS tool using two-comparison approaches- the longer oral health screening tool known as the Oral Health Impact Profile (OHIP-14) and an oral assessment by trained study dentists. METHODS: Pregnant women were recruited for this study as part of a larger randomised controlled trial of a Midwifery Initiated Oral Health (MIOH) program. Pregnant women completed the MOS and OHIP-14 as part of their initial assessment undertaken by 38 trained and accredited midwives. A dental assessment was conducted for all women in the intervention group using three trained study dentists with high inter rater reliability. RESULTS: Two hundred and eleven pregnant women participated in the validation of the MOS tool. Results from both approaches found the MOS tool to have high sensitivity, correctly identifying 88-94 % of women at risk of poor dental health, and low specificity (14-21 %). CONCLUSIONS: This study has shown that the MOS tool can be successfully implemented by midwives during a woman's first antenatal visit and can identify up to 94 % of women at risk of poor oral health and needing a dental referral. The tool has the potential to be transferable to other antenatal care providers and could be incorporated into hospital obstetric database systems.

Hippocampal volume in older adults at risk of cognitive decline: the role of sleep, vascular risk, and depression.

BACKGROUND AND OBJECTIVES: Decreased hippocampal volume in older adults is associated with neurodegenerative and psychiatric diseases. Several modifiable risk factors have been associated with the size of this structure, however the relative contribution of these factors to hippocampal atrophy is unclear. This study aimed to examine the relationship between modifiable risk factors and hippocampal volume in older adults at risk of cognitive decline. METHODS: Two hundred and eighteen participants (mean age = 67.3 years, MMSE = 28.6) with mood and/or memory complaints underwent clinical and neuropsychological assessment, and magnetic resonance imaging. Measures of depression, global cognitive functioning, exercise, vascular health, cognitive reserve, sleep, and memory were collected. Hippocampal volumes were derived using image segmentation as implemented by FMRIB Software Library. RESULTS: Smaller hippocampal volumes were strongly associated with poorer verbal learning and memory as well as diagnoses of either multiple or amnestic mild cognitive impairment. Based on univariate correlations, multivariable regressions were performed (controlling for age and total intracranial volume) to determine which modifiable risk factors were associated with hippocampal volume. For the left hippocampus, poor sleep efficiency and greater than five years untreated depressive illness remained significant predictors. For the right hippocampus, diabetes and low diastolic blood pressure significant predictors. CONCLUSIONS: Although their contribution is small, lower sleep efficiency, low blood pressure, diabetes, and untreated depression are associated with reduced hippocampal volumes. Studies exploring the impact of early intervention for these risk factors on hippocampal integrity are warranted.

Clinical and Cognitive Correlates of Structural Hippocampal Change in "At-Risk" Older Adults.

With estimates of dementia expected to rise over the coming decades, there is interest in understanding the factors associated with promoting neuroprotection and limiting neurodegeneration. In this study, we examined the change in the volume of the hippocampus over a 2-month period in 34 older people "at risk" of cognitive decline (mean age = 66.8 years, 38% male). Factors that were examined included cognitive reserve, neuropsychological functioning, depression as well as a lifestyle (cognitive training) intervention. The results showed that over a 2-month period, increases in hippocampal size were associated with having higher premorbid intellect, greater occupational attainment, superior memory, and higher levels of functioning. Conversely, depression and disability were associated with decreases in hippocampal volume. Cognitive training was not associated with changes in hippocampal volume. These findings suggest that factors associated with cognitive reserve, cognition and depression may play an integral pathophysiological role in determining hippocampal volumes in "at-risk" older adults.
