Free bus fares, bus use and physical activity: An exploratory cross-sectional study.

ISSUE ADDRESSED: Public transport (PT) users often accumulate more physical activity (PA) than private motor vehicle users and financial incentives may increase PT use. Responding to rising petrol prices, from 28 March to 1 May 2022, the Tasmanian government made public bus use fare-free. This exploratory study examined the perceived impact of fare-free buses on bus use and PA. METHODS: Tasmanian adults who had used the fare-free buses (N = 548) completed an online survey (4 May-14 June 2022). Quantitative data were analysed using descriptive and inferential methods and responses to open-ended questions categorised. RESULTS: Over the fare-free period, 46% of participants reported more bus use-average weekly bus trips increased from 3.0 to 4.0 (p < 0.001). Most (81%) participants, including 36% (n = 33/93) who were not previous bus users, planned continued bus use despite financial cost. Total PA was reported higher (36%), the same (60%) and lower (4%) than usual during the fare-free period. Higher total PA was more common amongst those reporting increased bus use (n = 186/240; 78%). Responses to open-ended questions revealed: bus use-related PA gain was through walking to/from bus stops, more frequently attending PA settings (e.g., the gym) and unexpected walking due to bus service limitations; household-level cost savings, improved travel opportunities and better social/mental health were additional fare-free benefits. CONCLUSIONS/SO WHAT: Fare-free buses were commonly perceived to increase bus use and PA. Intervention studies would determine if PA and financially incentivised PT have a causal relationship. Individual- and societal-level health economic analysis of free PT is warranted.

Tracking of serum lipid levels from childhood to adulthood: Systematic review and meta-analysis.

BACKGROUND AND AIMS: The utility of lipid screening in pediatric settings for preventing adult atherosclerotic cardiovascular diseases partly depends on the lifelong tracking of lipid levels. This systematic review aimed to quantify the tracking of lipid levels from childhood and adolescence to adulthood. METHODS: We systematically searched MEDLINE, Embase, Web of Science, and Google Scholar in March 2022. The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO; ID: CRD42020208859). We included cohort studies that measured tracking of lipids from childhood or adolescence (<18 years) to adulthood (≥18) with correlation or tracking coefficients. We estimated pooled correlation and tracking coefficients using random-effects meta-analysis. Risk of bias was assessed with a review-specific tool. RESULTS: Thirty-three studies of 19 cohorts (11,020 participants) were included. The degree of tracking from childhood and adolescence to adulthood differed among lipids. Tracking was observed for low-density lipoprotein cholesterol (pooled r = 0.55-0.65), total cholesterol (pooled r = 0.51-0.65), high-density lipoprotein cholesterol (pooled r = 0.46-0.57), and triglycerides (pooled r = 0.32-0.40). Only one study included tracking of non-high-density lipoprotein cholesterol (r = 0.42-0.59). Substantial heterogeneity was observed. Study risk of bias was moderate, mostly due to insufficient reporting and singular measurements at baseline and follow-up. CONCLUSIONS: Early-life lipid measurements are important for predicting adult levels. However, further research is needed to understand the tracking of non-high-density lipoprotein cholesterol and the stability of risk classification over time, which may further inform pediatric lipid screening and assessment strategies.

Tracking of apolipoprotein B levels measured in childhood and adolescence: systematic review and meta-analysis.

To quantify the tracking of apolipoprotein B (apoB) levels from childhood and adolescence and compare the tracking of apoB with low-density lipoprotein (LDL) cholesterol, a systematic search of MEDLINE, Embase, Web of Science, and Google Scholar was performed in October 2023 (PROSPERO protocol: CRD42022298663). Cohort studies that measured tracking of apoB from childhood/adolescence (< 19 years) with a minimum follow-up of 1 year, using tracking estimates such as correlation coefficients or tracking coefficients, were eligible. Pooled correlations were estimated using random-effects meta-analysis. Risk of bias was assessed with a review-specific tool. Ten studies of eight unique cohorts involving 4677 participants met the inclusion criteria. Tracking of apoB was observed (pooled r = 0.63; 95% confidence interval [CI] = 0.53-0.71; I2 = 96%) with no significant sources of heterogeneity identified. Data from five cohorts with tracking data for both lipids showed the degree of tracking was similar for apoB (pooled r = 0.59; 95% CI = 0.55-0.63) and LDL cholesterol (pooled r = 0.58; 95% CI = 0.47-0.68). Study risk of bias was moderate, mostly due to attrition and insufficient reporting. CONCLUSION: ApoB levels track strongly from childhood, but do not surpass LDL cholesterol in this regard. While there is strong evidence that apoB is more effective at predicting ASCVD risk than LDL cholesterol in adults, there is currently insufficient evidence to support its increased utility in pediatric settings. This also applies to tracking data, where more comprehensive data are required. WHAT IS KNOWN: • Apolipoprotein B is a known cause of atherosclerotic cardiovascular disease. • Apolipoprotein B levels are not typically measured in pediatric settings, where low-density lipoprotein cholesterol remains the primary lipid screening measure. WHAT IS NEW: • This meta-analysis of 10 studies showed apolipoprotein B levels tracked strongly from childhood but did not exceed low-density lipoprotein cholesterol in this regard. • More comprehensive tracking data are needed to provide sufficient evidence for increased utility of apolipoprotein B in pediatric settings.

trips4health: a single-blinded randomised controlled trial incentivising adult public transport use for physical activity gain.

BACKGROUND: Public transport users tend to accumulate more physical activity than non-users; however, whether physical activity is increased by financially incentivising public transport use is unknown. The trips4health study aimed to determine the impact of an incentive-based public transport intervention on physical activity. METHODS: A single-blinded randomised control trial of a 16-week incentive-based intervention involved Australian adults who were infrequent bus users (≥ 18 years; used bus ≤ 2 times/week) split equally into intervention and control groups. The intervention group were sent weekly motivational text messages and awarded smartcard bus credit when targets were met. The intervention group and control group received physical activity guidelines. Accelerometer-measured steps/day (primary outcome), self-reported transport-related physical activity (walking and cycling for transport) and total physical activity (min/week and MET-min/week) outcomes were assessed at baseline and follow-up. RESULTS: Due to the COVID pandemic, the trial was abandoned prior to target sample size achievement and completion of all assessments (N = 110). Steps/day declined in both groups, but by less in the intervention group [-557.9 steps (-7.9%) vs.-1018.3 steps/week (-13.8%)]. In the intervention group, transport-related physical activity increased [80.0 min/week (133.3%); 264.0 MET-min/week (133.3%)] while total physical activity levels saw little change [35.0 min/week (5.5%); 25.5 MET-min/week (1.0%)]. Control group transport-related physical activity decreased [-20.0 min/week (-27.6%); -41.3 MET-min/week (-17.3%)], but total physical activity increased [260.0 min/week (54.5%); 734.3 MET-min/week (37.4%)]. CONCLUSION: This study found evidence that financial incentive-based intervention to increase public transport use is effective in increasing transport-related physical activity These results warrant future examination of physical activity incentives programs in a fully powered study with longer-term follow-up. TRIAL REGISTRATION: This trial was registered with the Australian and New Zealand Clinical Trials Registry August 14th, 2019: ACTRN12619001136190; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=377914&isReview=true.

A prospective study of the impact of COVID-19-related restrictions on activities and mobility upon physical activity, travel behaviour and attitudes.

Background and aims: Public health measures adopted to contain the spread of COVID-19 included restrictions on activities and mobility as people were asked to stay at home and schools moved to online learning. This may have increased risk of non-communicable disease by limiting recreational and transport-related physical activity. Building on an existing study, we assessed changes in self-reported and device-measured physical activity and travel behaviour before, during and after the peak of local COVID-19 outbreak and restrictions (March-July 2020). We examined beliefs in effectiveness of strategies to increase active and public transport after restrictions were reduced. Methods: A longitudinal study of adult infrequent bus users (average ≤ 2 trips per week; n = 70; 67% women) in Hobart, Australia. One-week assessment periods at four separate timepoints (before, during, 0-3 months after, and 3-6 months after the peak restrictions period) involved wearing an accelerometer, daily transport diaries, online surveys and tracking bus smartcard boardings. Results: Physical activity (especially among older participants), bus use and private motor vehicle use declined significantly during or 0-3 months after the peak restrictions period and returned to pre-restrictions levels by 3-6 months after the peak restrictions period, except bus use which remained significantly lower. Retrospective surveys overstated declines in bus use and active transport and self-reports understated declines in physical activity. Social distancing and improving service efficiency and frequency were seen as effective strategies for increasing bus use after restrictions but belief in effectiveness of distancing decreased over time. Conclusions: When restrictions on mobility are increased, supportive health promotion measures are needed to prevent declines in physical activity, particularly for older adults. Public transport systems need capacity to implement temporary distancing measures to prevent communicable disease transmission. Providing convenient, flexible, and efficient options for public transport may help to replenish public transport use after restrictions are reduced.

Improving measurement of harms from others' drinking: Using item-response theory to scale harms from others' heavy drinking in 10 countries.

INTRODUCTION: The heavy drinking of others may negatively affect an individual on several dimensions of life. Until now, there is scarce research about how to judge the severity of various experiences of such harms. This study aims to empirically scale the severity of such harm items and to determine who is at most risk of these harms. METHODS: We used population-based survey data from 10 countries of the GENAHTO project (Gender and Alcohol's Harms to Others, data collection: 2011-2016). Questions about harms from others' drinking asked about verbal and physical harm, damage of belongings, traffic accidents, harassment, threatening behaviour, family and financial problems. We used item response theory methods (IRT) to scale severity of the aforementioned items. To acknowledge culturally based variations in different countries, we assessed 'differential item functioning'. RESULTS: The items 'family problems', 'financial problems' and 'clothes and property damage' as well as 'physical harm' were scaled as more severe in most countries compared to other items. Substantial differential item functioning was present in more than half of the country pairings. The item 'financial problems' was most often differentially scaled. Younger people who drank more, as well as women (compared to men), reported more harm. DISCUSSION AND CONCLUSIONS: Using IRT, we were able to evaluate grades of severity in harms from others' drinking. IRT scaling yielded in similar rankings of items as reported from other studies. However, empirical scaling allows for more differentiated severity scaling than simple summary scores and is more sensitive to cultural differences.

Socio-demographic, behavioural and health-related characteristics associated with active commuting in a regional Australian state: Evidence from the 2016 Tasmanian Population Health Survey.

ISSUE ADDRESSED: Physical activity is lower and rates of preventable common diseases are higher in regional/rural than urban Australia. Active commuting (walking/bicycling to get from one place to another) may benefit health through increased physical activity, but most evidence of its correlates come from urban studies. This study aimed to investigate associations between active commuting, socio-demographic characteristics, behaviours, total physical activity and health in a regional/rural Australian state. METHODS: This study used data from the 2016 Tasmanian Population Health Survey, a representative cross-sectional self-report survey of 6,300 adults in Tasmania, Australia. Logistic regression modelling investigated associations between socio-demographic, behavioural and health characteristics and past week active commuting frequency. RESULTS: In multivariable models, being younger, having tertiary qualifications, living in a socio-economically advantaged area, being physically active, having a healthy body mass index and good/excellent self-rated health were associated with engaging in more active commuting. Inner regional dwellers were no more likely than outer regional dwellers to actively commute after covariate adjustment. CONCLUSION: Strategies to promote active commuting in regional/rural areas might consider targeting older adults, those less educated, those living in socio-economically disadvantaged areas, those less physically active, those with poorer health and those with higher body mass index. Research could further investigate why these groups appear to be less active for commuting purposes. SO WHAT?: Increasing physical activity and active commuting may help to reduce rates of preventable common diseases in regional/remote areas.

Children's experience of physical harms and exposure to family violence from others' drinking in nine societies.

AIM: To study caregiver reports of children's experience of physical harm and exposure to family violence due to others' drinking in nine societies, assess the relationship of harm with household drinking pattern and evaluate whether gender and education of caregiver affect these relationships. METHOD: Using data on adult caregivers from the GENAHTO (Gender and Alcohol's Harm to Others) project, child alcohol-related injuries and exposure of children to alcohol-related violence (CAIV) rates are estimated by country and pooled using meta-analysis and stratified by gender of the caregiver. Households with and without heavy or harmful drinker(s) (HHD) are compared assessing the interaction of caregiver gender on the relationship between reporting HHD and CAIV, adjusting for caregiver education and age. Additionally, the relationship between caregiver education and CAIV is analysed with meta-regression. RESULTS: The prevalence of CAIV varied across societies, with an overall pooled mean of 4% reported by caregivers. HHD was a consistent correlate of CAIV in all countries. Men and women in the sample reported similar levels of CAIV overall, but the relationship between HHD and CAIV was greater for women than for men, especially if the HHD was the most harmful drinker. Education was not significantly associated with CAIV. CONCLUSION: One in 25 caregivers with children report physical or family violence harms to children because of others' drinking. The adjusted odds of harm are significantly greater (more than four-fold) in households with a heavy or harmful drinker, with men most likely to be defined as this drinker in the household.

Do gender differences in the relationship between living with children and alcohol consumption vary by societal gender inequality?

INTRODUCTION AND AIMS: To better understand the relationship between alcohol consumption and living with children, we assessed whether the association varied for men and women across diverse countries and whether this relationship was moderated by country-level gender inequality. DESIGN AND METHODS: We used Hierarchical Linear Modelling to analyse data from 32 surveys conducted in 27 countries. Measures included whether the participant was a drinker versus abstainer in past 12 months, annual number of drinks consumed, whether the respondent lived with children, gender (male/female) and age of respondent, and country-level gender inequality measured using the Gender Inequality Index. RESULTS: Annual drinks consumed was significantly lower for women living with children. Men living with children were generally more likely to be drinkers, and the relationship between annual consumption and living with children was moderated by cultural gender equality: specifically, men in countries with higher gender equality drank less if they lived with children while the association for men in lower equality countries was nonsignificant. DISCUSSION AND CONCLUSIONS: Although lower alcohol consumption was found generally for women living with children, this relationship was found only for men in countries where there was more gender equality. Given the high risk of harm to children from heavy consumption by adults with whom they live, prevention efforts need to strengthen prevention of heavy consumption by parents and other who live with children, especially for men who live with children in low gender equality countries.

Improving measurement of harms from others' drinking: A key informant study on type and severity of harm.

AIMS: Some types of harms experienced because of others' drinking (AHTO) may produce greater negative effects than other harms. However, AHTO survey items were developed to measure type, not severity, of harm. We aimed to compare the perceived severity of a comprehensive list of AHTO items to assess consistency in subjective ratings of severity, facilitate a more nuanced analysis and identify strategies to improve measurement of AHTO in epidemiological surveys. METHODS: Thirty-six leaders of national alcohol surveys (conducted between 1997 and 2016) from 23 countries rated the typical severity of negative effects on the victim of each of 48 types of AHTO using a scale from zero (no negative effect) to 10 (very severe negative effect). The survey leaders were also asked to provide open-ended feedback about each harm and the severity-rating task generally. RESULTS: Of 48 harm items, five were classified as extreme severity (mean rating ≥8), 17 as high (≥6 <8), 25 as moderate (≥4 <6), and one as low (≤4). We used two-way random effects models to estimate absolute agreement intraclass correlation coefficients (AA-ICC) and consistency of agreement intraclass correlation coefficients (CA-ICC). Results showed that there was fair to excellent absolute agreement and consistency of agreement among "experts'' ratings of the severity of harms from others' drinking (single measures CA-ICC = 0.414, single measures AA-ICC = 0.325; average CA-ICC = 0.940, average AA-ICC = 0.914). Harms to children, and harms causing physical, financial, practical, or severe emotional impacts were rated most severe. CONCLUSIONS: When designing new AHTO surveys and conducting analyses of existing data, researchers should pay close attention to harms with high perceived severity to identify effective ways to prevent severe AHTO and reduce the negative health and social impacts of AHTO. In-depth analyses of specific sub-sets of harms and qualitative interviews with victims of severe AHTO may prove useful.

Cross-sectional surveys of financial harm associated with others' drinking in 15 countries: Unequal effects on women?

INTRODUCTION AND AIMS: That physical, emotional and social problems occur not only to drinkers, but also to others they connect with, is increasingly acknowledged. Financial harms from others' drinking have been seldom studied at the population level, particularly in low- and middle-income countries. Whether financial harm and costs from others' drinking inequitably affect women is little known. The study's aim is to compare estimates and correlates of alcohol's financial harm to others than the drinker in 15 countries. METHODS AND MATERIALS: Cross-sectional surveys of Alcohol's Harm To Others (AHTO) were conducted in Australia, Brazil, Chile, Denmark, India, Ireland, Lao PDR, New Zealand, Nigeria, Sri Lanka, Sweden, Switzerland, Thailand, the US and Vietnam. PARTICIPANTS: 17,670 men and 20,947 women. MEASUREMENT: The prevalence of financial harm in the last year was assessed as financial trouble and/or less money available for household expenses because of someone else's drinking. ANALYSIS: Meta-analysis and country-level logistic regression of financial harm (vs. none), adjusted for gender, age, education, rurality and participant drinking. RESULTS: Under 3.2 % of respondents in most high-income countries reported financial harm due to others' drinking, whereas 12-22 % did in Thailand, Sri Lanka and India. Financial harm from others' drinking was significantly more common among women than men in nine countries. Among men and women, financial harm was significantly more prevalent in low- and middle- than in high-income countries. CONCLUSIONS: Reports of financial harm from others' drinking are more common among women than among men, and in low- and middle-income than in high-income countries.

Cross-National Comparisons and Correlates of Harms From the Drinking of People With Whom You Work.

BACKGROUND: While research in high-income countries (HICs) has established high costs associated with alcohol's harm to others (AHTO) in the workplace, scant attention has been paid to AHTO in the workplace in lower- or middle-income countries (LMICs). AIM: To compare estimates and predictors of alcohol's impacts upon coworkers among workers in 12 countries. METHODS: Cross-sectional surveys from 9,693 men and 8,606 women employed in Switzerland, Australia, the United States, Ireland, New Zealand, Chile, Nigeria, Lao PDR, Thailand, Vietnam, India, and Sri Lanka. Five questions were asked about harms in the past year because of coworkers' drinking: Had they (i) covered for another worker; (ii) worked extra hours; (iii) been involved in an accident or close call; or had their (iv) own productivity been reduced; or (v) ability to do their job been affected? Logistic regression and meta-analyses were estimated with 1 or more harms (vs. none) as the dependent variable, adjusting for age, sex, rurality of location, and the respondent worker's own drinking. RESULTS: Between 1% (New Zealand) and 16% (Thailand) of workers reported that they had been adversely affected by a coworker's drinking in the previous year (with most countries in the 6 to 13% range). Smaller percentages (<1% to 12%) reported being in an accident or close call due to others' drinking. Employed men were more likely to report harm from coworkers' drinking than employed women in all countries apart from the United States, New Zealand, and Vietnam, and own drinking pattern was associated with increased harm in 5 countries. Harms were distributed fairly equally across age and geographic regions. Harm from coworkers' drinking was less prevalent among men in HICs compared with LMICs. CONCLUSIONS: Workforce impairment because of drinking extends beyond the drinker in a range of countries and impacts productivity and economic development, particularly affecting men in LMICs.

The contexts of heavy drinking: A systematic review of the combinations of context-related factors associated with heavy drinking occasions.

BACKGROUND: The amount of alcohol consumed during an occasion can be influenced by physical and social attributes of the setting, characteristics and state of individuals, and the interactions of these components. This systematic review identifies and describes the specific combinations and sequences of context-related factors that are associated with heavy drinking occasions. MATERIALS AND METHODS: We conducted a systematic literature search of MEDLINE, Embase and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Eligible articles were event-level and event-based studies that quantitatively analysed associations of sequences or combinations of context-related factors with event-level alcohol consumption. We extracted information on study design, sample, variables, effect estimates and analytical methods. We compiled a list of combinations and sequences associated with heavier drinking (i.e., 'risky contexts') and with lighter drinking ('protective contexts'). The review protocol was registered with PROSPERO (registration number: CRD42018089500). RESULTS: We screened 1902 retrieved records and identified a final sample of 65 eligible studies. Daily mood, day of week, location and drinking group characteristics are important drivers of whether an individual engages in a heavy drinking occasion. The direction and magnitude of some associations differed by gender, age, personality and motives, such that in particular social or physical contexts, some people may feel compelled to drink more while others are compelled to drink less. Very few sequences of factors were reported as being associated with event-level alcohol consumption. CONCLUSIONS: Contexts or factors are experienced in specific sequences that shape the broader drinking context and influence drinking behaviours and consequences but are under-studied. Event-level studies such as those using ecological momentary assessment can harness new technologies for data collection and analysis to improve understandings of why people engage in heavy drinking. Continued event-level research will facilitate public health interventions and policies that reduce heavy drinking and alcohol-related harms.

The social location of harm from others' drinking in 10 societies.

AIMS: Survey data from 10 diverse countries were used to analyse the social location of harms from others' drinking: which segments of the population are more likely to be adversely affected by such harm, and how does this differ between societies? METHODS: General-population surveys in Australia, Chile, India, Laos, New Zealand, Nigeria, Sri Lanka, Thailand, United States and Vietnam, with a primary focus on the social location of the harmed person by gender, age groups, rural/urban residence and drinking status. Harms from known drinkers were analysed separately from harms from strangers. RESULTS: In all sites, risky or moderate drinkers were more likely than abstainers to report harm from the drinking of known drinkers, with risky drinkers the most likely to report harm. This was also generally true for harm from strangers' drinking, although the patterns were more mixed in Vietnam and Thailand. Harm from strangers' drinking was more often reported by males, while gender disparity in harm from known drinkers varied between sites. Younger adults were more likely to experience harm both from known drinkers and from strangers in some, but not all, societies. Only a few sites showed significant urban/rural differences, with disparities varying in direction. In multivariate analyses, most relationships remained, although some were no longer significant. CONCLUSION: The social location of harms from others' drinking, whether known or a stranger, varies considerably between societies. One near-commonality among the societies is that those who are themselves risky drinkers are more likely to suffer harm from others' drinking.

Women's role in the rise in drinking in Australia 1950-80: an age-period-cohort analysis of data from the Melbourne Collaborative Cohort Study.

BACKGROUND AND AIMS: In Australia, as in many countries, alcohol consumption increased dramatically during the second half of the 20th century, with increased availability of alcohol, relaxation of attitudes towards drinking and shifting roles and opportunities for women as facilitating factors. We sought to investigate drinking trends by gender and birth cohort in Australia during this period. DESIGN: Retrospective cohort study. SETTING, PARTICIPANTS AND MEASUREMENTS: Using the usual frequency and quantity of beverage-specific alcohol intake for 10-year periods from age 20, reported retrospectively from 40 789 participants aged 40-69 years (born 1920-49) at recruitment to the Melbourne Collaborative Cohort Study in 1990-94, we compared trends in alcohol consumption by sex in Australia between 1950 and 1990. Participants' average daily consumption for age decades were transformed to estimated intakes for 1950, 1960, 1970, 1980 and 1990. FINDINGS: Alcohol consumption was higher for men than women during each decade. Alcohol consumption increased for both sexes in the 1950s, 1960s and 1970s, and fell after 1980. The rise before 1980 was roughly equal in absolute terms for both sexes, but much greater relative to 1950 for women. Women born during 1930-39 and 1940-49 drank more alcohol during early-middle adulthood (ages 20-40) than women born during 1920-29. In the 1980s, the fall was greater in absolute terms for men, but roughly equal relative to 1950 for both sexes. In both sexes, the decline in drinking in the 1980s for birth-decade cohorts was roughly in parallel. CONCLUSIONS: Specific birth cohorts were influential in the rise in alcohol consumption by Australian women born in 1920-49 after World War II. Much of the convergence with men's drinking after 1980 reflects large reductions in drinking among men.

Harm from Known Others' Drinking by Relationship Proximity to the Harmful Drinker and Gender: A Meta-Analysis Across 10 Countries.

BACKGROUND: Drinking is a common activity with friends or at home but is associated with harms within both close and extended relationships. This study investigates associations between having a close proximity relationship with a harmful drinker and likelihood of experiencing harms from known others' drinking for men and women in 10 countries. METHODS: Data about alcohol's harms to others from national/regional surveys from 10 countries were used. Gender-stratified random-effects meta-analysis compared the likelihood of experiencing each, and at least 1, of 7 types of alcohol-related harm in the last 12 months, between those who identified someone in close proximity to them (a partner, family member, or household member) and those who identified someone from an extended relationship as the most harmful drinker (MHD) in their life in the last 12 months. RESULTS: Women were most likely to report a close male MHD, while men were most likely to report an extended male MHD. Relatedly, women with a close MHD were more likely than women with an extended MHD to report each type of harm, and 1 or more harms, from others' drinking. For men, having a close MHD was associated with increased odds of reporting some but not all types of harm from others' drinking and was not associated with increased odds of experiencing 1 or more harms. CONCLUSIONS: The experience of harm attributable to the drinking of others differs by gender. For preventing harm to women, the primary focus should be on heavy or harmful drinkers in close proximity relationships; for preventing harm to men, a broader approach is needed. This and further work investigating the dynamics among gender, victim-perpetrator relationships, alcohol, and harm to others will help to develop interventions to reduce alcohol-related harm to others which are specific to the contexts within which harms occur.

Is there gender convergence in risky drinking when taking birth cohorts into account? Evidence from an Australian national survey 2001-13.

BACKGROUND AND AIMS: Recent studies have argued that there has been substantial gender convergence in alcohol consumption. However, many of these rely on comparisons of different cohorts and do not adjust for age differences in male and female drinking patterns. We aimed to examine (1) whether the gender gap in risky drinking in Australia narrowed between 2001 and 2013, (2) if the evidence for gender convergence (or divergence) was consistent across age groups and (3) how a cohort-focused analysis of gender convergence compared with an age-focused approach. DESIGN: Repeated cross-sectional data from five waves of the National Drug Strategy Household Survey (2001, 2004, 2007, 2010, 2013). Interaction terms in logistic and linear regression models were used to test for significantly different trends between men and women. SETTING: Australia. PARTICIPANTS: Australians aged 14 years and older (n = 125 215) who provided data on alcohol consumption in the National Drug Strategy Household Survey. MEASUREMENTS: Prevalence of long-term risky drinking (average of 20 g or more per day) and prevalence of risky single occasion drinking (12 or more sessions of 50 g or more). FINDINGS: Gender differences were large for all age groups except adolescents (14-17-year-olds), with men typically reporting levels of drinking at least twice as high as women across the study period. Overall, there was statistically significant gender convergence in alcohol use measures showing a slight decrease in men's drinking and a slight increase in women's drinking. However, when age-specific analyses were conducted gender convergence was only observed for 50-69-year-olds. CONCLUSIONS: In Australia, gender convergence in risky drinking since 2001 has been evident only in people aged 50-69 years.

Experience of harm from others' drinking and support for stricter alcohol policies: Analysis of the Australian National Drug Strategy Household Survey.

BACKGROUND: Previous research indicates that those who have experienced alcohol-related harm from others are more likely to support stricter alcohol control policies. This study investigates the association between types of harm experienced because of others' drinking and support for stricter alcohol control policies. METHODS: Data from 20,570 Australians aged 18 and over who completed the 2013 National Drug Strategy Household Survey was used. Questions about experience of alcohol-related harm from others - being put in fear and abuse (verbal or physical) - were asked. Support for stricter alcohol control policies was quantified by a mean policy support score across 18 alcohol policy questions. RESULTS: Twenty seven percent of respondents reported harm from someone's drinking. Respondents who were put in fear had a higher level of support for stricter alcohol control policies than respondents who were not harmed (p<0.001), regardless of whether they were abused or not. Conversely, respondents who experienced abuse but were not put in fear did not significantly differ in their support for stricter policies from those who experienced no harm. CONCLUSION: It is the apprehension of harm (i.e. having been put in fear), and not the experience of harm itself (i.e. abuse), which is related to people's support for stricter alcohol policies. These findings suggest that perceiving others' intoxication as dangerous to oneself may motivate support for stricter alcohol policies.
