RESUMEN
BACKGROUND: Different forms of alcohol-related harm (e.g., hangovers, fighting) may confer differential risk of clinically relevant alcohol problems. We examine: (i) patterns of transition in experiencing alcohol-related harms across adolescence; (ii) whether factors in early adolescence predict transition patterns; and (iii) whether transition patterns predict later alcohol use disorder (AUD) symptoms. METHODS: We used a longitudinal Australian cohort (n = 1828) to model latent class transition patterns of alcohol-related harms across three timepoints (Mage = 13.9, 16.8, 18.8 years). Regression models assessed whether child, peer, and parent factors in early adolescence (Mage = 12.9) predicted harms transition patterns and whether these patterns predicted AUD symptoms in early adulthood (Mage = 19.8). RESULTS: Five transition patterns characterized most of the cohort (n ≈ 1609, 88.0%): (i) minimal harms (n ≈ 381, 20.8%); (ii) late physiological harms (n ≈ 702, 38.4%); (iii) early physiological harms (n ≈ 226, 12.4%); (iv) late all harms (n ≈ 131, 7.2%); and (v) gradual all harms (n ≈ 169, 9.2%). With late physiological harms as the reference, females had increased risk of experiencing early physiological harms (relative risk [RR]: 2.15; 99.5% CI: 1.19, 3.90). Late all harms (RR: 1.71; CI: 1.19, 2.47) and gradual all harms (RR: 1.84; CI: 1.37, 2.47) were each associated with increased odds of meeting criteria for AUD, even when patterns of alcohol consumption are considered. CONCLUSIONS: Adolescents display heterogeneous transition patterns across physiological and psychosocial alcohol-related harms. Females are at greater risk of experiencing early physiological harms. Experience of both physiological and psychosocial harms in late adolescence is an important and potentially modifiable precursor to clinically relevant alcohol problems in early adulthood.

Background: Parents are the main supplier of alcohol to children but it is not known whether mothers and fathers equally contribute to the supply of alcohol to their female and male children as these children transition to adulthood.Objectives: i) to determine whether the gender of the parent is associated with the gender of the adolescent offspring when alcohol is supplied and ii) whether the gender of the parent supplying is associated with gender differences in adolescent binge drinking and alcohol related harms.Methods: Longitudinal cohort of 1,927 (males = 1052) Australian adolescents (mean age 12.9 years), recruited in 2010/11 from schools in Australia and surveyed annually for six years. We assessed the association between adolescent and parent gender related to subsequent adolescent drinking, binge drinking (>4 standard drinks), and alcohol-related harms.Results: At mean age of 12.9 years about one in ten children report parental supply of alcohol which increases to about four in ten children by 17.8 years. Mothers consistently more often supply their daughters with alcohol than their sons, [Wave 5 OR 1.77 (1.53,2.05)], while mothers less often supply sons than their daughters, [Wave 5 OR 0.82 (0.71,0.95)]. Mothers' supply of alcohol to daughters predicts substantially increased odds of daughters binge drinking, [OR 1.67 (1.10,2.53)] and experiencing alcohol related harms, [OR 1.65 (1.10,2.48)].Conclusion: There is a need to involve both mothers and fathers and to equally target female and male children in programs to reduce the harmful consequences of parental supply of alcohol to their children.

Importance: Cytisine is more effective than placebo and nicotine replacement therapy for smoking cessation. However, cytisine has not been tested against the most effective smoking cessation medication, varenicline, which is associated with adverse events known to lead to discontinuation of therapy. Objective: To examine whether standard cytisine treatment (25 days) was at least as effective as standard varenicline treatment (84 days) for smoking cessation. Design, Setting, and Participants: This noninferiority, open-label randomized clinical trial with allocation concealment and blinded outcome assessment was undertaken in Australia from November 2017 through May 2019; follow-up was completed in January 2020. A total of 1452 Australian adult daily smokers willing to make a quit attempt were included. Data collection was conducted primarily by computer-assisted telephone interview, but there was an in-person visit to validate the primary outcome. Interventions: Treatments were provided in accordance with the manufacturers' recommended dosage: cytisine (n = 725), 1.5-mg capsules taken 6 times daily initially then gradually reduced over the 25-day course; varenicline (n = 727), 0.5-mg tablets titrated to 1 mg twice daily for 84 days (12 weeks). All participants were offered referral to standard telephone behavioral support. Main Outcomes and Measures: The primary outcome was 6-month continuous abstinence verified using a carbon monoxide breath test at 7-month follow-up. The noninferiority margin was set at 5% and the 1-sided significance threshold was set at .025. Results: Among 1452 participants who were randomized (mean [SD] age, 42.9 [12.7] years; 742 [51.1%] women), 1108 (76.3%) completed the trial. Verified 6-month continuous abstinence rates were 11.7% for the cytisine group and 13.3% for the varenicline group (risk difference, -1.62% [1-sided 97.5% CI, -5.02% to ∞]; P = .03 for noninferiority). Self-reported adverse events occurred less frequently in the cytisine group (997 events among 482 participants) compared with the varenicline group (1206 events among 510 participants) and the incident rate ratio was 0.88 (95% CI, 0.81 to 0.95; P = .002). Conclusions and Relevance: Among daily smokers willing to quit, cytisine treatment for 25 days, compared with varenicline treatment for 84 days, failed to demonstrate noninferiority regarding smoking cessation.

BACKGROUND: Women-specific factors exist that increases vulnerability to drug-related harms from injection drug use, including blood-borne viruses (BBVs), but gender-based differences in BBV prevalence have not been systematically examined. METHODS: We conducted meta-analyses to estimate country, regional, and global prevalence of serologically confirmed human immunodeficiency virus (HIV), hepatitis C virus (HCV; based on detection of anti-HCV antibody), and hepatitis B virus (HBV; based on detection of HBV surface antigen) in people who inject drugs (PWID), by gender. Gender-based differences in the BBV prevalence (calculated as the risk among women relative to the risk among men) were regressed on country-level prevalence and inequality measures (Gender inequality index, Human development index, Gini coefficient, and high, low or middle income of the country). RESULTS: Gender-based differences varied by countries and regions. HIV prevalence was higher among women than men in sub-Saharan Africa (relative risk [RR], 2.8; 95% confidence interval [CI], 1.8-4.4) and South Asia (RR, 1.7; 95% CI, 1.1-2.7); anti-HCV was lower among women in the Middle East and North Africa (RR, 0.6; 95% CI, .5-.7) and East and Southeast Asia (RR, 0.8; 95% CI, .7-.9). Gender-based differences varied with country-levels of the BBV prevalence in the general population, human development, and income distribution. CONCLUSION: HIV was more prevalent in women who inject drugs as compared to their male counterparts in some countries, but there is variation between and within regions. In countries where women are at higher risks, there is a need to develop gender-sensitive harm-reduction services for the particularly marginalized population of women who inject drugs.

BACKGROUND: Why adolescents' drinking is associated with their parents' drinking remains unclear. We examined associations in a prospective cohort study, adjusting for socio-demographic characteristics and family factors. METHODS: We recruited 1927 children from grade 7 classes (mean age 13 years), and one of their parents, in three Australian states, contacted participants annually from 2010 to 2014, and analysed data from assessments at ages 13, 14, 15 and 16 years. We used the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) subscale to identify hazardous drinking in parents (score ≥5) and children (score ≥3) and constructed mixed-effect logistic regression models, accounting for clustering within school and adjusting for likely confounders. We evaluated the sensitivity of estimates by imputing missing values assuming the data were missing at random vs. missing not at random. RESULTS: Parent hazardous drinking predicted mid-adolescent hazardous drinking, e.g. 15 years olds whose parents [adjusted odds ratio (aOR) 2.00; 95% confidence interval 1.51-2.64] or parents' partners (aOR 1.94; 1.48-2.55) were hazardous drinkers had higher odds of being hazardous drinkers at age 16. The magnitude of univariate associations changed little after adjusting for covariates, and sensitivity analyses confirmed the robustness of the association, across a wide range of assumptions about the missing data. CONCLUSIONS: The associations between parents' and their adolescent children's hazardous drinking are unlikely to be due to confounding by socio-demographic and family factors. Parents should be encouraged, and supported by public policy, to reduce their own alcohol consumption in order to reduce their children's risk of becoming hazardous drinkers.

RESUMEN
BACKGROUND: Maternal alcohol consumption in pregnancy may have adverse effects on child gross motor (GM) development. There have been few human studies on this topic, particularly ones examining low exposure. This study examined the association between prenatal alcohol exposure (PAE) and infant GM development at 12-months of age. METHODS: Participants were 1324 women recruited from antenatal clinics in Sydney and Perth, Australia. Maternal and paternal alcohol use was assessed in pregnancy via interview; offspring GM development was measured at 12-months with the Bayley Scales of Infant Development (BSID-III). RESULTS: Any alcohol use in pregnancy was common: 56.1%, of pregnant women drank early in Trimester one (0-6 weeks), however this reduced to 27.9% on average thereafter and at predominantly low levels. However, infant BSID GM scale scores were not found to differ significantly as a function of PAE in the first 6-weeks (low, moderate, binge or heavy PAE), nor with low PAE across pregnancy. CONCLUSIONS: We found no evidence to suggest that low PAE is associated with measurable impairment in infant GM development at 12-months. Further research is needed to examine potential PAE impacts on GM development in heavier exposure groups and through the childhood years when subtle GM deficits may be more detectable.

INTRODUCTION: The quality of the mother-child relationship in the first year of life has far reaching implications across the life course (Bornstein in Annu Rev Psychol 65:121-158, 2014). Yet little is known about predictors of maternal bonding and emotional availability in early infancy. In this study we examined the extent to which postnatal bonding, maternal mental health, and substance use at 8-weeks postpartum predicted mother-infant bonding (self-report) and mother emotional availability (observational) at 12-months of age. METHODS: Data were obtained from an Australian longitudinal cohort study of pregnancy (n = 308). Data were collected during pregnancy, at birth, and postnatally at 8-weeks and 12-months. RESULTS: The results show strong continuity between postnatal bonding at 8-weeks and 12-months. Early postpartum stress and depression were associated with bonding at 12-months; however, the effect did not persist after adjustment for bonding at 8-weeks. Tobacco use at 8-weeks, but no other indicators of mental health, predicted lower emotional availability scores at 12-months. DISCUSSION: Results suggest that the mother's felt bond to her child is stable across the first year of life and that early bonding is a more robust indicator of bonding at 12-months than a mother's mental health or substance use. These findings point to the importance of clinical and public health investments in establishing a strong bond between mother and child in the early postpartum period.

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.

BACKGROUND: Early alcohol initiation is common and has been associated with the development of alcohol problems. Yet, past research on the association of age of initiation with later problem drinking has produced inconsistent findings. Using prospective data from the Australian Parental Supply of Alcohol Longitudinal Study cohort, this study examined age of alcohol initiation, and of first drunkenness, and associations with subsequent drinking in adolescence. METHODS: A total of 1,673 parent-child dyads recruited through Australian secondary schools completed annual surveys for 5 years (grades 7 to 11). Limiting the sample to those adolescents who had initiated alcohol use by age 17 (n = 839), multinomial logistic regression models were used to examine associations between (i) age of initiation to alcohol use (consuming at least 1 full serve) and (ii) age of first drunkenness, and 2 outcomes: (i) binge drinking (consuming >4 standard drinks on a single occasion), and (ii) the total number of alcoholic drinks consumed in the past year, adjusted for a range of potential child, parent, family, and peer covariates. RESULTS: Fifty percent of adolescents reported alcohol use and 36% reported bingeing at wave 5 (mean age 16.9 years), and the mean age of initiation to alcohol use for drinkers was 15.1 years. Age of initiation was significantly associated with binge drinking and total quantity of alcohol consumed in unadjusted and adjusted models. Age of first drunkenness was associated with total quantity of alcohol consumed in unadjusted models but not adjusted models and was not associated with subsequent bingeing. CONCLUSIONS: Initiating alcohol use earlier in adolescence is associated with an increased risk of binge drinking and higher quantity of consumption in late secondary school, supporting an argument for delaying alcohol initiation for as long as possible to reduce the risk for problematic use in later adolescence and the alcohol-related harms that may accompany this use.

Aims: To assess the methodological quality and effectiveness of technology-based smoking cessation interventions in disadvantaged groups. Method: Four databases (EMBASE, Cochrane, Medline, and PsycInfo) were searched for studies conducted from 1980 to May 2016. Randomized controlled trials that compared a behavioral smoking cessation intervention delivered primarily through a technology-based platform (eg, mobile phone) with a no-intervention comparison group among disadvantaged smokers were included. Three reviewers assessed all relevant studies for inclusion, and one reviewer extracted study, participant and intervention-level data, with a subset crosschecked by a second reviewer. Results: Thirteen studies targeting disadvantaged smokers (n =4820) were included. Only one study scored highly in terms of methodological rigor on EPOC criteria for judging risk of bias. Of the 13 studies using a technology-based platform, most utilized websites (n = 5) or computer programs (n = 5), and seven additionally offered nicotine replacement therapy. Technology-based interventions increased the odds of smoking cessation for disadvantaged groups at 1 month (odds ratio [OR] 1.70, 95% confidence interval [CI] 1.10, 2.63), 3 months (OR 1.30, 95% CI 1.07, 1.59), 6 months (OR 1.29, 95% CI 1.03, 1.62), and 18 months post-intervention (OR 1.83, 95% CI 1.11, 3.01). Conclusion: Few methodologically rigorous studies were identified. Mobile phone text-messaging, computer- and website-delivered quit support showed promise at increasing quit rates among Indigenous, psychiatric and inpatient substance use disorder patients. Further research is needed to address the role technology-based interventions have on overcoming health inequalities to meet the needs of disadvantaged groups. Implications: This review provides the first quantitative evidence of the effectiveness of a range of technology-based smoking cessation interventions among disadvantaged smokers, with separate estimates on the basis of intervention type, and cessation outcome measure. Providing cost-effective, easily accessible and real-time smoking cessation treatment is needed, and innovative technology-based platforms will help reach this endpoint. These interventions need to be tested in larger scale randomized controlled trial designs and target broader disadvantaged groups. Data collection beyond 6 months is also needed in order to establish the efficacy of these intervention approaches on long-term cessation rates among disadvantaged population groups.

OBJECTIVES: Alcohol misuse and depression are commonly co-occurring conditions. To date, no review has examined the most efficacious treatment model for psychosocial treatment of co-occurring alcohol misuse and depression. This systematic review determined the: (i) methodological quality of publications examining psychosocial treatment of co-occurring alcohol misuse and depression using a sequential, parallel or integrated treatment model; and (ii) effectiveness of each dual treatment model compared to single treatment for those with co-occurring alcohol misuse and depression. METHODS: PubMed, Medline and PsycInfo databases were searched for studies which were included if they involved treatment for alcohol misuse and depression and could be classified into one of the three treatment models. Included studies were assessed using the Cochrane's Effective Practice and Organisation of Care risk of bias criteria. Relevant study characteristics and outcomes were extracted and are presented in a narrative review format. RESULTS: Seven studies met inclusion criteria. None were categorised as low risk on the risk of bias criteria. No studies examined a sequential model of treatment, three examined a parallel model and four examined an integrated model of dual-focussed treatment. The studies examining the parallel model and two out of four studies examining the effectiveness of an integrated model demonstrated greater improvement for alcohol or depression outcomes compared to control conditions. CONCLUSION: Evidence for the psychosocial treatment of co-occurring alcohol misuse and depression is limited to a handful of studies. The evidence has several methodological limitations, which impact the interpretation of the findings. Therefore, while international guidelines recommend integrated dual-focussed treatment for co-occurring conditions, there is little evidence supporting the superiority of this treatment format for co-occurring alcohol misuse and depression. High-quality research demonstrating improvements in patient outcomes is required to ensure recommendations for clinical practice are based on strong empirical evidence.

BACKGROUND: Despite opioid analgesics being essential for pain relief, use has been inadequate in many countries. We aim to provide up-to-date worldwide, regional, and national data for changes in opioid analgesic use, and to analyse the relation of impediments to use of these medicines. METHODS: We calculated defined daily doses for statistical purposes (S-DDD) per million inhabitants per day of opioid analgesics worldwide and for regions and countries from 2001 to 2013, and we used generalised estimating equation analysis to assess longitudinal change in use. We compared use data against the prevalence of some health disorders needing opioid use. We surveyed 214 countries or territories about impediments to availability of these medicines, and used regression analyses to establish the strength of associations between impediments and use. FINDINGS: The S-DDD of opioid analgesic use more than doubled worldwide between 2001-03 and 2011-13, from 1417 S-DDD (95% CI -732 to 3565; totalling about 3.01 billion defined daily doses per annum) to 3027 S-DDD (-1162 to 7215; totalling about 7.35 billion defined daily doses per annum). Substantial increases occurred in North America (16,046 S-DDD [95% CI 4032-28,061] to 31,453 S-DDD [8121-54,785]), western and central Europe (3079 S-DDD [1274-4883] to 9320 S-DDD [3969-14,672]), and Oceania (2275 S-DDD [763-3787] to 9136 S-DDD [2508-15,765]). Countries in other regions have shown no substantial increase in use. Impediments to use included an absence of training and awareness in medical professionals, fear of dependence, restricted financial resources, issues in sourcing, cultural attitudes, fear of diversion, international trade controls, and onerous regulation. Higher number of impediments reported was significantly associated with lower use (unadjusted incidence rate ratio 0.39 [95% CI 0.29-0.52]; p<0.0001), but not when adjusted for gross domestic product and human development index (0.91 [0.73-1.14]; p=0.4271). INTERPRETATION: Use of opioid analgesics has increased, but remains low in Africa, Asia, Central America, the Caribbean, South America, and eastern and southeastern Europe. Identified impediments to use urgently need to be addressed by governments and international agencies. FUNDING: International Narcotics Control Board, UN.

BACKGROUND: The social gradient in smoking rates persist with an overrepresentation of smoking and its associated harms concentrated within lower socioeconomic status (SES) populations. Low-SES smokers are motivated to quit but face multiple barriers when engaging a quit attempt. An understanding of the current treatment service model from the perspectives of treatment-seeking low-SES smokers is needed to inform the design of alternative smoking cessation support services tailored to the needs of low-SES populations. This qualitative study aimed to: i) explore low-SES smokers' recent quitting experiences; ii) assess factors that impact treatment engagement; and iii) determine the acceptability and feasibility of alternative approaches to smoking cessation. METHOD: Low-SES participants (n = 24) previously enrolled in a smoking cessation RCT participated in either a semi-structured focus group or in-depth telephone interview. Data was obtained and analysed using thematic analysis from October 2015 to June 2016. Analysis was deductive from the interview guide and supplemented inductively. RESULTS: Participants expressed feelings of guilt and shame around their smoking behaviour and experienced stigmatisation for their smoking. Guilt, shame, and stigmatisation negatively impacted treatment seeking behaviours with most avoiding current quit services. Costs of pharmacotherapy and treatment adherence were commonly cited barriers to treatment success. Electronic-cigarettes were perceived to be unsafe due to uncertainty on their legal status and regulatory restrictions. Technology-based text-messaging quit support was endorsed as a more favourable alternative compared to existing behavioural treatment services. CONCLUSION: Stigmatisation was commonly endorsed and acted as an impediment to current treatment utilisation. Electronic-cigarettes may present a viable harm reduction alternative, but their likely uptake in socioeconomically disadvantaged groups in Australia is limited by smokers' uncertainty about their regulation and legality. Mobile phone based cessation support may provide an alternative to telephone counselling and overcome the stigmatisation low-SES smokers face while trying to quit.

BACKGROUND: Financial stress is a barrier to successful smoking cessation and a key predictor of relapse. Little is known about the financial situation of low-income Australian daily smokers. This study aims to describe and investigate associations between the financial functioning, tobacco use and quitting behaviours of low income daily smokers. METHODS: Low-income Australian adult smokers in the 'Financial Intervention for Smoking Cessation Among Low-income Smokers (FISCALS) randomised clinical trial completed a structured telephone questionnaire. RESULTS: The median number of cigarettes typically smoked by the 1047 participants was 23 per day. The median spent on tobacco per week was AU$80. Three quarters (73.0%) reported some financial stress and 43.2% reported smoking-induced deprivation. Financial stress was significantly associated with deprivation (IRR: 1.23, 95% CI 1.21, 1.26, p < 0.001). There were no significant associations either between adjusted financial stress or deprivation and motivation to quit or certainty of quit success. CONCLUSIONS: Financial stress and smoking induced deprivation were prevalent among low-income daily smokers, but they were not associated with motivation to quit. Smoking cessation interventions need to be responsive to the role financial stress plays in reducing quit attempts and increasing relapse.

Background Mother-infant bonding provides the foundation for secure attachment through the lifespan and organizes many facets of infant social-emotional development, including later parenting. Aims To describe maternal bonding to offspring across the pregnancy and postnatal periods, and to examine a broad range of sociodemographic and psychosocial predictors of the maternal-offspring bond. Methods Data were drawn from a sample of 372 pregnant women participating in an Australian population-based longitudinal study of postnatal health and development. Participants completed maternal bonding questionnaires at each trimester and 8 weeks postnatal. Data were collected on a range of sociodemographic and psychosocial factors. Results Bonding increased significantly through pregnancy, in quality and intensity. Regression analyses indicated that stronger antenatal bonding at all time points (trimesters 1 through 3) predicted stronger postnatal bonding. Older maternal age, birth mother being born in a non-English speaking country, mother not working full time, being a first-time mother, breast-feeding problems, and baby's crying behavior all predicted poorer bonding at 8 weeks postpartum. Conclusion These novel findings have important implications for pregnant women and their infant offspring, and for health care professionals working in perinatal services. Importantly, interventions to strengthen maternal-fetal bonding would be beneficial during pregnancy to enhance postnatal bonding and infant health outcomes.

Objective To investigate the obesogenic influence of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) on infant weight at birth and 12 months postpartum in an Australian general population sample. Methods Data on 1,305 pregnant women were collected on prepregnancy BMI and GWG through maternal interview, on infant weight at birth through hospital records, and on infant weight 12 months postbirth through direct measurement. Relationships between prepregnancy, gestational weight exposures, and infant weight outcomes were assessed with and without adjustment for potential confounding. Results We observed a 14 to 24 g increase in infant birth weight for every 1 kg increase in maternal weight (infant birth weight: ß(BMI) = 0.014, p < 0.000; ß(GWG) = 0.012, p < 0.000; and 12 months: ß(BMI) = 0.018, p < 0.000; ß(GWG) = 0.024, p < 0.000). Effects remained after adjustment for potential confounders (infant birth weight: ß(BMI) = 0.014, p < 0.000; ß(GWG) = 0.012, p < 0.001; and 12 months: ß(BMI)= 0.017, p ≤ 0.033; ß(GWG) = 0.023, p = 0.001). However, the effects observed were small, and there was no evidence that GWG mediated relationships between preconception BMI and infant weight. Conclusion In a general population sample, there is a significant but not substantial observed relationship between maternal prepregnancy BMI and GWG and infant weight outcomes, suggesting a minor role for these factors at a population level.

INTRODUCTION: Tobacco smoking co-occurs with behavioural risk factors including diet, alcohol use and obesity. However, the association between behavioural risk factors and heavy smoking (>20cig/day) compared to light-moderate smoking is unknown. The link between behavioural risk factors and future smoking for both ex and current smokers is also unknown. This study sought to examine these relationships. It is hypothesised that behavioural risk factors will be more strongly associated with heavy smoking. METHOD: Data from Wave 7 (2007) of the Household and Labour Dynamics in Australia (HILDA) survey was analysed using logistic regression to determine relationships between diet (fruit and vegetable consumption, and unhealthy diet choices), alcohol consumption, obesity and physical activity with light-moderate smoking and heavy smoking. The association between these risk factors and future smoking (2008) was assessed for current and ex-smokers (2007). RESULTS: Obese respondents were less likely to be light/moderate smokers (RRR: 0.53; 95% CI: 0.43, 0.66) but not heavy smokers. Those who consume confectionary weekly were less likely to be light/moderate smokers (RRR: 0.73; 95% CI: 0.61, 0.87), but not heavy smokers. Smokers in 2007 were more likely to continue smoking in 2008 if they consumed 1-4 drinks per occasion (OR: 2.52; 95% CI: 1.13, 5.62). Ex-smokers in 2007 were less likely to relapse in 2008 if they consumed recommended levels of both fruit and vegetables (OR: 0.31; CI: 0.10, 0.91). CONCLUSION: The relationships between heavy smoking and behavioural risk factors differ from moderate-light smoking. Future primary care interventions would benefit from targeting multiple risk factors, particularly for heavy smokers.

The emotional bond that a mother feels towards her baby is critical to social, emotional and cognitive development. Maternal health and wellbeing through pregnancy and antenatal bonding also play a key role in determining bonding postnatally, but the extent to which these relationships may be disrupted by poor mental health or substance use is unclear. This study aimed to examine the extent to which mother-fetal bonding, substance use and mental health through pregnancy predicted postnatal mother-infant bonding at 8 weeks. Participants were 372 women recruited from three metropolitan hospitals in Australia. Data was collected during trimesters one, two and three of pregnancy and 8 weeks postnatal using the Maternal Antenatal Attachment Scale (MAAS), Maternal Postnatal Attachment Scale (MPAS), the Edinburgh Antenatal and Postnatal Depression Scale (EPDS), the Depression and Anxiety Scales (DASS-21), frequency and quantity of substance use (caffeine, alcohol and tobacco) as well as a range of demographic and postnatal information. Higher antenatal bonding predicted higher postnatal bonding at all pregnancy time-points in a fully adjusted regression model. Maternal depressive symptoms in trimesters two and three and stress in trimester two were inversely related to poorer mother-infant bonding 8 weeks postnatally. This study extends previous work on the mother's felt bond to her developing child by drawing on a large sample of women and documenting the pattern of this bond at three time points in pregnancy and at 8 weeks postnatally. Utilising multiple antenatal waves allowed precision in isolating the relationships in pregnancy and at key intervention points. Investigating methods to enhance bonding and intervene in pregnancy is needed. It is also important to assess maternal mental health through pregnancy.

BACKGROUND: Epidemiological studies report markedly varying rates of adolescent alcohol involvement. Despite being a common adolescent behavior, a potential cause of this variation is that consumption of sips is either not measured or not distinguished from consumption of whole beverages. METHODS: Participants were 1,843 grade 7 adolescents recruited across 49 Australian secondary schools (M age = 12.4, SD = 0.5). Quantity and frequency of lifetime and past 6-month consumption were assessed, distinguishing between sipping and drinking. For comparison with international population surveys, quantity was reported as any consumption, sipping only, and drinking only. RESULTS: Combining sipping and drinking into a single category, lifetime consumption was reported by 67.3% of the present sample. Distinguishing lifetime consumption by sipping and drinking: only 7.8% of adolescents had consumed a whole beverage; the remaining 59.6% had only sipped. Consumption of whole beverages was mostly limited to 1 to 2 drinks (84.2% of drinkers). Sipping and drinking were also infrequent: 78.2% of sipping and 60.4% of drinking, occurred less than monthly. Heavy episodic consumption was uncommon (1.2% of the sample). When other population studies were inspected, a clear trend for higher drinking rates were found in those studies where sipping was counted as drinking and vice versa. CONCLUSIONS: Consumption of whole beverages appears infrequent in early adolescence, as sipping, but not drinking, was common in our sample. Comparing the present data with international population consumption measures highlights the need to more precisely measure and report adolescent consumption, particularly in relation to sipping.
