RESUMEN

This study aims to estimate the prevalence and correlation of household levels of water, sanitation, and hygiene (WASH), including the identification of areas where WASH facilities are unimproved in Nepal. The study population was 11,040 household heads, using the data collected in the Nepal Demographic and Health Survey 2016. Logistic regression analysis was performed and crude odds ratios (OR) with 95% confidence intervals (CI) using a 0.05 significance level are presented. Getis-Ord Gi* statistics were used to identify the hot and cold spot areas of unimproved WASH. GPS locations of WASH points were used for spatial analysis. Approximately 95% of households had an improved water source, 84% had improved sanitation facilities, 81% had a fixed place for handwashing, and 47% had soap and water. Education, wealth, and ecology were significantly associated with WASH. The people from the hills were less likely to have an improved water source (OR = 0.32; 95% CI: 0.16-0.64) than those from the plain. Households with a poor wealth index had 78% lower odds of having an improved water source compared to households with a rich wealth index. Respondents from Madhes Province had lower odds (OR = 0.15; 95% CI: 0.08-0.28) and Gandaki Pradesh had the highest odds (OR = 2.92; 95% CI: 1.52-5.61) of having improved sanitation facilities compared to Province 1. Respondents aged 35-44 years had higher odds (OR = 1.16; 95% CI: 1.04-1.29) of having soap and water available compared to those aged 45 years and older. Education and geographical disparities were the factors associated with having reduced access to WASH. These findings suggest the need to focus on advocacy, services, and policy approaches.

RESUMEN

BACKGROUND AND AIMS: Observational studies have demonstrated that the pneumococcal polysaccharide vaccine (PPV) is associated with reduced risk of cardiovascular events. This may be mediated through IgM antibodies to OxLDL, which have previously been associated with cardioprotective effects. The Australian Study for the Prevention through Immunisation of Cardiovascular Events (AUSPICE) is a double-blind, randomised controlled trial (RCT) of PPV in preventing ischaemic events. Participants received PPV or placebo once at baseline and are being followed-up for incident fatal and non-fatal myocardial infarction or stroke over 6 years. METHODS: A subgroup of participants at one centre (Canberra; n = 1,001) were evaluated at 1 month and 2 years post immunisation for changes in surrogate markers of atherosclerosis, as pre-specified secondary outcomes: high-sensitive C-reactive protein (CRP), pulse wave velocity (PWV), and carotid intima-media thickness (CIMT). In addition, 100 participants were randomly selected in each of the intervention and control groups for measurement of anti-pneumococcal antibodies (IgG, IgG2, IgM) as well as anti-OxLDL antibodies (IgG and IgM to CuOxLDL, MDA-LDL, and PC-KLH). RESULTS: Concentrations of anti-pneumococcal IgG and IgG2 increased and remained high at 2 years in the PPV group compared to the placebo group, while IgM increased and then declined, but remained detectable, at 2 years. There were statistically significant increases in all anti-OxLDL IgM antibodies at 1 month, which were no longer detectable at 2 years; there was no increase in anti-OxLDL IgG antibodies. There were no significant changes in CRP, PWV or CIMT between the treatment groups at the 2-year follow-up. CONCLUSIONS: PPV engenders a long-lasting increase in anti-pneumococcal IgG, and to a lesser extent, IgM titres, as well as a transient increase in anti-OxLDL IgM antibodies. However, there were no detectable changes in surrogate markers of atherosclerosis at the 2-year follow-up. Long-term, prospective follow-up of clinical outcomes is continuing to assess if PPV reduces CVD events.

RESUMEN

Individuals with Lynch syndrome (LS), have an increased risk of developing cancer. Common genetic variants of telomerase reverse transcriptase (TERT) have been associated with a wide range of cancers, including colorectal cancer (CRC) in LS. We combined genotype data from 1881 LS patients, carrying pathogenic variants in MLH1, MSH2 or MSH6, for rs2075786 (G>A, intronic variant), 1207 LS patients for rs2736108 (C>T, upstream variant) and 1201 LS patients for rs7705526 (C>A, intronic variant). The risk of cancer was estimated by heterozygous/homozygous odds ratio (OR) with mixed-effects logistic regression to adjust for gene/gender/country of sample origin considering family identity. The AA genotype of SNP rs2075786 is associated with 85% higher odds at developing cancer compared to GG genotype in MSH2 pathogenic variant carriers (p = 0.0160). Kaplan-Meier analysis also shows an association for rs2075786; the AA allele for MSH2 variant carriers confers risk for earlier diagnosis of LS cancer (log-rank p = 0.0011). We report a polymorphism in TERT to be a possible modifier of disease risk in MSH2 pathogenic variant carriers. The rs2075786 SNP in TERT is associated with a differential risk of developing cancer for MSH2 pathogenic variant carriers. Use of this information has the potential to personalise screening protocols for LS patients.

RESUMEN

BACKGROUND: Mast cells (MCs) and basophils are important in asthma pathophysiology, however direct measurement is difficult, and clinical and inflammatory associations in severe asthma are poorly understood. Transcriptomic hallmarks of MCs/basophils may allow their measurement in sputum using gene expression. OBJECTIVES: This study sought to develop and validate a sputum MC/basophil gene signature and investigate its relationship to inflammatory and clinical characteristics of severe asthma. METHODS: A total of 134 candidate MC/basophil genes (identified by the Immunological Genome Project Consortium) were screened in sputum microarray for differential expression among control subjects (n = 18), patients with eosinophilic (n = 29), and patients with noneosinophilic asthma (n = 30). Candidate genes were validated by confirming correlation of gene expression with flow cytometry-quantified sputum MCs and basophils in a separate asthma cohort (n = 20). The validated gene signature was measured in a severe asthma cohort (n = 81), and inflammatory and clinical associations were tested. RESULTS: Through microarray screening and subsequent validation, we found quantitative PCR gene expression of 8 targets correlated with sputum MCs/basophils: TPSAB1/TPSB2, CPA3, ENO2, GATA2, KIT, GPR56, HDC, SOCS2. In severe asthma, MC/basophil genes were associated with eosinophilic airway inflammation (GATA2, TPSB2, CPA3, GPR56, HDC, SOCS2), blood eosinophils (TPSB2, CPA3, GATA2, SOCS2, FCER1A, HDC), fractional exhaled NO (GATA2, SOCS2), decreased lung function (KIT, ENO2), and moderate exacerbation history (GATA2, SOCS2). CONCLUSIONS: Quantitative PCR-based measures reflect varying sputum MC/basophil abundance, demonstrating associations of MCs/basophils with eosinophilic inflammation, spirometry and exacerbation history in severe asthma.

RESUMEN

OBJECTIVE: To examine perceived problems with involvement in medical decision making among people with breast cancer from various phases of the cancer care trajectory. METHODS: Breast cancer outpatients (n = 663) from 13 treatment centres completed a survey of perceived involvement in treatment and care decisions in the last month, psychological distress, demographic and clinical factors. A subsample (n = 98) from three centres completed a follow-up survey on preferred and perceived treatment decision making roles. RESULTS: Overall, 112 (17 %) of 663 respondents from 13 oncology centres had experienced problems with involvement in decision making about their treatment and care in the last month, and of these, 36 (32 %) reported an unmet need for help with this problem. Elevated psychological distress was associated with 5.7 times the odds of reporting this problem and 6.6 times the odds of reporting this unmet need in the last month. Among the follow-up subsample (n = 98), 39% (n = 38) reported discordance between preferred and perceived role in a major treatment decision. Psychological distress was not associated with this outcome. CONCLUSION: Psychological distress was significantly associated with recently experiencing problems with involvement in treatment and care decisions, but not with misalignment of preferred and perceived roles in prior major treatment decisions. PRACTICE IMPLICATIONS: There is a need to maintain support for patient involvement in healthcare decisions across the cancer care continuum.

RESUMEN

Background: Cognitive impairment following a minor stroke or transient ischemic attack (TIA) is common; however, due to diagnostic difficulties, the prevalence and underlying cause of impairment remain poorly defined. We compared cognition in patients after a minor stroke, TIA, or mimic event at three time points in the first year following the event. We examine whether cognitive impairment occurs following these events and whether this impairment differs based on the event type. Further, we measure whether these findings persist after controlling for age, education, and the presence of vascular risk factors and whether the presence of vascular risk factors, independent of event etiology, is associated with cognitive impairment. Lastly, we investigate whether increased stroke risk, as assessed by the ABCD2, is associated with reduced cognition. Methods: Medical information, a cognitive screening test, and a measure of executive functioning were collected from 613 patients (123 minor stroke, 175 TIA, and 315 mimics) using phone interviews at three time points in the first year following the event. Linear mixed models were used to determine the effect of event type, vascular risk factors, and predicted stroke risk on cognitive performance while controlling for confounders. Results: There was no relationship between event type and performance on either cognitive measure. When all confounders are controlled for, performance on the cognitive screening test was uniquely accounted for by the presence of heart failure, myocardial infarction, angina, and hypertension (all p < 0.047), whereas the measure of executive functioning was uniquely accounted for by the presence of hypertension and angina (all p < 0.032). Increased stroke risk also predicted performance on the cognitive screening test and the measure of executive functioning (all p < 0.002). Conclusions: Our findings indicate that cognitive impairment following a minor stroke or TIA may be attributed to the high prevalence of chronic vascular risk factors in these patients. This highlights the importance of long-term management of vascular risk factors beyond event recovery to reduce the risk of cognitive impairment. Increased stroke risk (i.e., ABCD2 score) was also associated with reduced cognition, suggesting that it may be helpful in signaling the need for further cognitive evaluation and intervention post-event.

RESUMEN

OBJECTIVES: During the perinatal period, 10-20% of women experience anxiety and/or depression. Untreated perinatal depression has the potential for adverse effects on the family and infant resulting in long-term deleterious consequences. This study measured the association between self-reported depression using the Edinburgh Postnatal Depression Scale scores, self-reported anxiety and neonatal birth outcomes. METHODS: A retrospective design was used with ObstetriX™ data retrieved from 16 metropolitan and rural hospitals in NSW, Australia during 2009-2014. Data were available for 53,646 singleton births. The Edinburgh Postnatal Depression Scale was used to identify self-reported depression while women self-reported pregnancy related anxiety. Regression modelling measured the effects of self-reported depression and self-reported pregnancy related anxiety on neonatal birth outcomes. Linear regression and logistic regression were used to model the effect on birth weight, gestational age, admission to NICU or the SCN, outcome (stillborn vs livebirth), and Apgar scores. Cox proportional hazards regression was used to estimate the effect on neonatal length of stay. RESULTS: Babies born to women self-reporting anxiety were more likely to have birth complications, be admitted to the nursery, had lower Apgar scores and longer hospital stays. Babies born to women self-identifying as experiencing a level of depression were more likely to have a lower birth weight, shorter gestational age, and, lower Apgar score. These babies were more likely to be admitted to the nursery with an increased length of stay. CONCLUSIONS: Perinatal anxiety and depression contribute to poor birth outcomes. Early detection of maternal perinatal anxiety and depression is an important step towards treatment interventions. More research is needed to identify models of care that are effective in identifying and managing perinatal depression and anxiety to improve birth outcomes for women and their babies.

RESUMEN

AIM: Previous studies, some dating back several decades, have recommended that the use of plain abdominal radiography should be curbed, particularly with the growth of more accurate imaging modalities. However, evidence from referral data suggests that plain abdominal radiography continues to be a commonly requested examination. The aim of this review was to explore the gap between evidence and practice by re-examining the evidence using a robust methodology, investigating the diagnostic accuracy of plain abdominal radiography. METHODS: Studies were identified from electronic databases and reference lists. Eligible studies provided data as to the sensitivity and specificity of plain abdominal radiography for either acute abdominal pain (Group A) or suspected intestinal obstruction (Group B). Version 2 of the Quality Assessment of Diagnostic Accuracy Studies was used to assess the quality of studies and hierarchical summary receiver operator characteristic curves and coupled forest plots were generated. RESULTS: Four studies evaluated plain abdominal radiography for acute abdominal pain (Group A) and 10 for suspected intestinal obstruction (Group B). Two studies investigated both presentations and were included in both groups. Methodological quality of studies was moderately high, though incorporation bias was a common limitation. Sensitivity for Group A studies ranged from 30 to 46%, with specificity from 75 to 88%. For Group B, the range of sensitivity was 48 to 96% and specificity from 50 to 100%. CONCLUSION: The results suggest that use of plain abdominal radiography could be substantially reduced, particularly for patients with undifferentiated acute abdominal pain. While some guidelines exist, there is sound argument for clinical decision rules for abdominal imaging to inform evidence-based clinical decision-making and radiology referrals.

RESUMEN

BACKGROUND: Accumulating evidence suggests that breastfeeding exclusivity and duration are positively associated with child cognition. This study investigated whether DNA methylation, an epigenetic mechanism modified by nutrient intake, may contribute to the link between breastfeeding and child cognition. The aim was to quantify the relationship between global DNA methylation and cognition and behavior at 4 years of age. METHODS: Child behavior and cognition were measured at age 4 years using the Wechsler Preschool and Primary Scale of Intelligence, third version (WPPSI-III), and Child Behavior Checklist (CBC). Global DNA methylation (%5-methylcytosines (%5mC)) was measured in buccal cells at age 4 years, using an enzyme-linked immunosorbent assay (ELISA) commercial kit. Linear regression models were used to quantify the statistical relationships. RESULTS: Data were collected from 73 children recruited from the Women and Their Children's Health (WATCH) study. No statistically significant associations were found between global DNA methylation levels and child cognition or behavior (p > .05), though the estimates of effect were consistently negative. Global DNA methylation levels in males were significantly higher than in females (median %5mC: 1.82 vs. 1.03, males and females, respectively, (p < .05)). CONCLUSION: No association was found between global DNA methylation and child cognition and behavior; however given the small sample, this study should be pooled with other cohorts in future meta-analyses.

RESUMEN

Objectives This study sought to determine, among a large sample of Australian general practice patients: (1) the prevalence of smoking among different levels of alcohol misuse; and (2) whether the associations between demographic characteristics and alcohol use differ according to smoking status. Methods A cross-sectional survey was administered from 2010 to 2011 to 3559 patients from 12 Australian urban general practices. Patients reported their demographic details, smoking status and their alcohol intake. Results The overall prevalence of reported concurrent smoking and alcohol misuse was 7.8%. Smokers were 3.81-fold more likely to have a higher level of alcohol consumption than non-smokers (95% confidence interval 3.13-4.63; P<0.0001). There was evidence that smoking was an effect modifier of the relationship between alcohol misuse and chronic illness. Conclusions There was an increasing prevalence of smoking with increasing level of alcohol consumption. In addition, those with chronic conditions who smoked had greater odds of higher levels of alcohol consumption. Preventative interventions for these substances are needed to reduce the burden associated with concurrent smoking and alcohol misuse. What is known about the topic? Tobacco and alcohol are the most commonly used substances and contribute to over 10million deaths annually. The risk of disease is high when using either of these substances, however, concurrent use is associated with a greatly compounded risk. Australian data is limited regarding the prevalence of concurrent tobacco and alcohol misuse, however, international studies suggest variation in prevalence rates between different clinical settings. What does this paper add? This study examined the prevalence of concurrent smoking and alcohol misuse among different levels of alcohol misuse severity within an Australian general practice setting. Additionally it explored whether the associations between demographic characteristics and alcohol use differ according to smoking status. What are the implications for practitioners? This study has important implications for disease prevention and the delivery of preventive health services by general practitioners. Considering one in 100 clinical treatments provided in general practice relate to preventative smoking or alcohol counselling, it is critical that efforts are made to ascertain risk factors such as smoking and alcohol misuse to increase treatment rates. General practitioners should consider screening for smoking and alcohol misuse opportunistically during routine clinical encounters, as well as screening for smoking or alcohol misuse if one or the other is present.

RESUMEN

: Amid concerns about increasing alcohol-related violence in licensed premises, Queensland introduced a system of risk-based licensing (RBL) in 2009, the first of five Australian jurisdictions to do so. Under RBL, annual license fees are supposed to reflect the risk of harm associated with the outlet's trading hours and record of compliance with liquor laws. The objective is to improve service and management practices thereby reducing patron intoxication and related problems. Using police data, we defined cases as assaults that occurred during so-called 'high-alcohol hours', and compared a pre-intervention period of 2004-2008 with the post-intervention period 2009-2014. We employed segmented linear regression, adjusting for year and time of assault (high vs. low alcohol hours), to model the incidence of (1) all assaults and (2) a subset that police indicated were related to drinking in licensed premises. We found a small decrease in all assaults (ß = -5 per 100,000 persons/year; 95% CI: 2, 9) but no significant change in the incidence of assault attributed to drinking in licensed premises (ß = -8; 95% CI: -18, 2). Accordingly, we concluded that the results do not support a hypothesis that RBL is effective in the prevention of harm from licensed premises. There may be value in trialing regulatory schemes with meaningful contingencies for non-compliance, and, in the meantime, implementing demonstrably effective strategies, such as trading hour restrictions, if the aim is to reduce alcohol-related violence.

RESUMEN

OBJECTIVE: Uptake of screening through the Australian National Bowel Cancer Screening Program remains low. General practice guidelines support the general practitioners' role to offer CRC screening. This study tests the effect that an intervention including point-of-care FOBT provision, printed screening advice and GP endorsement has on self-reported FOBT uptake. METHODS: A multisite, 1:1 parallel-arm, cluster-randomised controlled trial. Participants aged 50-74, at average risk of CRC and overdue for screening were recruited from four general practices in New South Wales, Australia, from September 2016 to May 2017. Self-report of FOBT up to eight weeks post baseline. RESULTS: A total of 336 participants consented to complete a baseline survey (64% consent rate), of which 123 were recruited into the trial (28 usual care days and 26 intervention days). Follow-up data was collected for 114 participants (65 usual care and 49 intervention). Those receiving the intervention had ten times greater odds of completing screening compared to usual care (39% vs. 6%; OR 10.24; 95%CI 2.9-36.6, p=0.0006). CONCLUSIONS: A multicomponent intervention delivered in general practice significantly increased self-reported FOBT uptake in those at average risk of CRC. Implications for public health: General practice interventions could serve as an important adjunct to the Australian National Bowel Cancer Screening Program to boost plateauing screening rates.

RESUMEN

BACKGROUND: Adequately preparing patients for medical interventions is an important component of quality healthcare. Nevertheless, few instruments for assessing patients' preparation exist. OBJECTIVES: To develop a psychometrically rigorous instrument to assess patients' perceptions of the quality of preparation. METHODS: An instrument to measure patients' preparation for medical interventions (MiPrep) was developed and tested with patients undergoing medical imaging, radiotherapy, or surgery. Patients were recruited and asked to complete 2 surveys. Survey A assessed patient and intervention characteristics. Survey B (postintervention) contained MiPrep to assess validity (face, content, and construct) and reliability (internal consistency and test-retest). RESULTS: A total of 869 (85%) patients consented to participate and 551 (63%) returned the postintervention survey. Face and content validity were demonstrated. Exploratory factor analysis identified 2 survey modules: receipt and adequacy of information (2 domains) and overall appraisal of patient-centered care (1 domain). Reliability was evidenced by adequate internal consistency (Cronbach α 0.81-0.89) and item-total correlations higher than 0.20. Nevertheless, individual item test-retest reliability requires further confirmation. The final instrument contained 27 items. CONCLUSIONS: The MiPrep instrument has evidence of being a valid and reliable instrument of preparation for medical interventions. Healthcare providers can use the instrument as a quality assurance tool to identify areas for improvement and areas of excellence in patients' preparation. Future studies should verify these findings in other populations and examine the divergent and predictive validity of the instrument.

RESUMEN

Studies investigating exceptionally long-lived (ELL) individuals, including genetic studies, have linked cardiovascular-related pathways, particularly lipid and cholesterol homeostasis, with longevity. This study explored the genetic profiles of ELL individuals (cases: n = 294, 95⁻106 years; controls: n = 1105, 55⁻65 years) by assessing their polygenic risk scores (PRS) based on a genome wide association study (GWAS) threshold of p < 5 × 10-5. PRS were constructed using GWAS summary data from two exceptional longevity (EL) analyses and eight cardiovascular-related risk factors (lipids) and disease (myocardial infarction, coronary artery disease, stroke) analyses. A higher genetic risk for exceptional longevity (EL) was significantly associated with longevity in our sample (odds ratio (OR) = 1.19⁻1.20, p = 0.00804 and 0.00758, respectively). Two cardiovascular health PRS were nominally significant with longevity (HDL cholesterol, triglycerides), with higher PRS associated with EL, but these relationships did not survive correction for multiple testing. In conclusion, ELL individuals did not have significantly lower polygenic risk for the majority of the investigated cardiovascular health traits. Future work in larger cohorts is required to further explore the role of cardiovascular-related genetic variants in EL.

RESUMEN

OBJECTIVES: To examine the effectiveness of different strategies for recruiting participants for a large Australian randomised controlled trial (RCT), the Australian Study for the Prevention through Immunisation of Cardiovascular Events (AUSPICE). DESIGN, SETTING, PARTICIPANTS: Men and women aged 55-60 years with at least two cardiovascular risk factors (hypertension, hypercholesterolaemia, overweight/obesity) were recruited for a multicentre placebo-controlled RCT assessing the effectiveness of 23-valent pneumococcal polysaccharide vaccine (23vPPV) for preventing cardiovascular events. METHODS: Invitations were mailed by the Australian Department of Human Services to people in the Medicare database aged 55-60 years; reminders were sent 2 weeks later. Invitees could respond in hard copy or electronically. Direct recruitment was supplemented by asking invitees to extend the invitation to friends and family (snowball sampling) and by Facebook advertising. MAIN OUTCOME: Proportions of invitees completing screening questionnaire and recruited for participation in the RCT. RESULTS: 21 526 of 154 992 invited people (14%) responded by completing the screening questionnaire, of whom 4725 people were eligible and recruited for the study. Despite the minimal study burden (one questionnaire, one clinic visit), the overall participation rate was 3%, or an estimated 10% of eligible persons. Only 16% of eventual participants had responded within 2 weeks of the initial invitation letter (early responders); early and late responders did not differ in their demographic or medical characteristics. Socio-economic disadvantage did not markedly influence response rates. Facebook advertising and snowball sampling did not increase recruitment. CONCLUSIONS: Trial participation rates are low, and multiple concurrent methods are needed to maximise recruitment. Social media strategies may not be successful in older age groups. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry, ACTRN12615000536561.

RESUMEN

BACKGROUND: Medical oncology outpatients are a group for whom advance care planning (ACP) activities are particularly relevant. Patient views can help prioritise areas for improving end of life communication. The study aimed to determine in a sample of medical oncology outpatients: (1) the perceived importance of participating in ACP activities; (2) the proportion of patients who have ever participated in ACP activities; and (3) the proportion of patients who had not yet participated in ACP activities who were willing to do so in next month. METHODS: Adult medical oncology outpatients in two Australian cancer treatment centres were consecutively approached to complete a pen-and-paper survey. Items explored perceived importance, previous participation, and willingness to participate across key ACP activities including: discussing wishes with their family or doctor; recording wishes in a written document; appointing a substitute decision maker (SDM); and discussing life-expectancy. RESULTS: 185 participants completed the survey (51% consent rate). Most patients agreed it was important to: discuss end of life wishes with family (85%) and doctors (70%) and formally record wishes (73%). Few had discussed end of life wishes with a doctor (11%), recorded their wishes (15%); chosen a SDM (28%); discussed life expectancy (30%); or discussed end of life wishes with family (30%). Among those who had not participated in ACP, most were willing to discuss life expectancy (66%); discuss end of life wishes with family (57%) and a doctor (55%); and formally record wishes (56%) in the next month. Fewer wanted to appoint a SDM (40%). CONCLUSION: Although medical oncology outpatients perceive ACP activities are important, rates of uptake are relatively low. The willingness of many patients to engage in ACP activities suggests a gap in current ACP practice. Efforts should focus on ensuring patients and families have clarity about the legal and other ramifications of ACP activities, and better education and training of health care providers in initiating conversations about end of life issues.

RESUMEN

BACKGROUND: Low birthweight is more common in infants of indigenous (Aboriginal and/or Torres Strait Islander) than of White Australian mothers. Controversy exists on whether fetal growth is normally different in different populations. OBJECTIVE: We sought to determine the relationships of birthweight, birthweight percentiles, and smoking with perinatal outcomes in indigenous vs nonindigenous infants to determine whether the White infant growth charts could be applied to indigenous infants. STUDY DESIGN: Data were analyzed for indigenous status, maternal age and smoking, and perinatal outcomes in 45,754 singleton liveborn infants of at least 20 weeks gestation or 400 g birthweight delivered in New South Wales, Australia, between June 2010 and July 2015. RESULTS: Indigenous infants (n=6372; 14%) had a mean birthweight 67 g lower than nonindigenous infants (P<.0001; with adjustment for infant sex and maternal body mass index). Indigenous mean birthweight percentile was 4.2 units lower (P<.0001). Adjustment for maternal age, smoking, body mass index, and infant sex reduced the difference in birthweight/percentiles to nonsignificance (12 g; P=.07). CONCLUSION: Disparities exist between indigenous and non-indigenous Australian infants for birthweight, birthweight percentile, and adverse outcome rates. Adjustment for smoking and maternal age removed any significant difference in birthweights and birthweight percentiles for indigenous infants. Our data indicate that birthweight percentiles should not be adjusted for indigenous ethnicity because this normalizes disadvantage; because White and indigenous Australians have diverged for approximately 50,000 years, it is likely that the same conclusions apply to other ethnic groups. The disparities in birthweight percentiles that are associated with smoking will likely perpetuate indigenous disadvantage into the future because low birthweight is linked to the development of chronic noncommunicable disease and poorer educational attainment; similar problems may affect other indigenous populations.

RESUMEN

BACKGROUND: It is hypothesised that epigenetic mechanisms including DNA methylation may underlie the relationship between early-life nutrition and child cognitive outcomes. This study aimed to identify dietary patterns associated with the intake of one-carbon metabolism nutrients in children aged 2-3 years. METHODS: A validated 120-item semi-quantitative food frequency questionnaires at 2-3 years of age were used to estimate the intake of one-carbon metabolism nutrients (methionine, folate, choline and vitamins B2, B6, B12) and to quantify mean number of serves consumed of the food groups specified by the Australian Guide to Healthy Eating (AGHE). Descriptive statistics were used to analyse the contribution of each food group and food items to the total intake of one-carbon metabolism nutrients. Linear regression was used to test for linear trends in food group servings by nutrient intake quintiles. RESULTS: No child (n = 60) from the Women And Their Children's Health (WATCH) study consumed the recommended number of serves for all AGHE food groups. Dairy and alternatives (18-44%), discretionary foods (6-33%) and meat and alternatives (6-31%) were the main sources of most one-carbon metabolism nutrients. Most child intakes of one-carbon metabolism nutrients exceeded the nutrient reference values (NRVs), except for the intake of choline, for which the mean intake was 9% below the adequate intake (AI). CONCLUSION: Dairy and alternatives, discretionary foods and meat and alternatives food groups contributed significantly to the children's intake of one-carbon metabolism nutrients. The children generally had low intakes of meat and alternative foods, which may explain their inadequate intake of choline.

RESUMEN

BACKGROUND: Recently the dementia field has shifted focus away from the early diagnosis debate in favour of 'timely' diagnosis. 'Timely' diagnosis disclosure takes into consideration the preferences and unique circumstances of the individual. Determining when diagnosis disclosure is 'timely' may be particularly complex if there are differing views between the individual, their family, and their health care providers regarding disclosure. This study explores the preferences of consumers regarding when a diagnosis of dementia should be communicated. METHODS: A cross-sectional survey was conducted with English-speaking adults attending outpatient clinics at an Australian hospital. Participants were recruited by a research assistant in the clinic waiting room and invited to complete the survey on a web-connected iPad. The survey included questions examining socio-demographics and experience with dementia. Two scenarios were used to explore preferences for timing of diagnosis disclosure. RESULTS: Of 446 participants, 92% preferred a diagnosis of dementia to be disclosed as soon as possible. Preferences were not associated with socio-demographics or previous dementia experience. Most participants also preferred disclosure to occur as soon as possible if their spouse or partner was diagnosed with dementia (88%). There was strong correlation between preferences for self and preferences for spouse (0.91). CONCLUSIONS: These findings provide guidance to health care providers about preferences for disclosure of a dementia diagnosis, and may help to overcome potential barriers to timely diagnosis. As the prevalence of dementia increases, consumers' preference for diagnosis to occur as soon as possible has important implications for the health system.
