Effective alcohol policies are associated with reduced consumption among demographic groups who drink heavily.

BACKGROUND: Alcohol policies stand out among other noncommunicable disease-relevant policies for the lack of uptake. Composite indicators have been developed to measure the effects of alcohol control policy. We investigated whether drinking patterns among demographic groups from general population samples of drinkers from diverse countries are associated with alcohol control policy as measured by the International Alcohol Control (IAC) Policy Index. METHODS: Representative samples of adult drinkers from 10 countries (five high-income and five middle-income) were surveyed about alcohol consumption, using beverage and location-specific questions. MEASUREMENTS: The IAC Policy Index was analyzed with frequency, typical occasion quantity, and volume consumed. Analyses used mixed models that included interactions between country IAC Policy Index score and age group, gender, and education level. FINDINGS: Each increase in IAC policy index score (reflecting more effective alcohol policy) was associated with a 13.9% decrease in drinking frequency (p = 0.006) and a 16.5% decrease in volume (p = 0.001). With each increase in IAC Policy Index score, both genders decreased for all three measures, but men less so than women. Women decreased their typical occasion quantity by 1.2% (p = 0.006), frequency by 3.1% (p < 0.001), and total volume by 4.2% (p < 0.001) compared to men. Low and mid-education groups decreased their typical occasion quantity by 2.6% (p < 0.001) and 1.6% (p = 0.001), respectively, compared to high education, while for drinking frequency the low education group increased by 7.0% (p < 0.001). There was an overall effect of age (F = 19.27, p < 0.0001), with 18-19 and 20-24-year-olds showing the largest decreases in typical occasion quantity with increasing IAC policy index score. CONCLUSIONS: The IAC Policy Index, reflecting four effective policies, was associated with volume and frequency of drinking across 10 diverse countries. Each increase in the IAC Policy Index was associated with lower typical quantities consumed among groups reporting heavy drinking: young adults and less well-educated. There is value in implementing such alcohol policies and a need to accelerate their uptake globally.

Perception of harm and benefits of cannabis use among adolescents from Latin America and Caribe / Percepción de daños y beneficios del uso de cannabis entre adolescentes de América Latina y Caribe / Percepção de danos e benefícios do uso de cannabis entre adolescentes da América Latina e Caribe

ABSTRACT Objective: to investigate the perception of harms and benefits associated with cannabis use among adolescents and how regulatory changes might affect their intention to use marijuana. Method: this multi-centric cross-sectional survey study. participants included 2717 students aged 15-17 from 10 cities in Belize, Brazil, Chile, Colombia, Dominican Republic, Jamaica, Mexico, St. Kitts and Nevis, and Trinidad and Tobago. Results: an average lifetime prevalence of cannabis use of 30.6% (25.8% past year, 15.8% past 30 days). Most participants reported that their closest friends use cannabis (60%); many (55%) stated that they would not use marijuana, even if it were legally available. Conclusion: statistics revealed that a strong perception of benefits, a low perception of risk, and friends' use of cannabis were associated with individual use as well as intention to use within a hypothetical context of regulatory change.

Perception of harms and benefits associated with marijuana use among adolescents in st kitts-nevis - caribe / Percepção de danos e benefícios associados ao uso de maconha entre adolescentes em st kitts-nevis-caribe / Percepción de daños y beneficios relacionados al uso de la marihuana entre adolescentes en st kitts-nevis en el caribe

ABSTRACT Objective: this investigation examined adolescents' perception of the harms and benefits of marijuana use and how regulatory changes may affect their intent to use marijuana. Method: this cross-sectional survey gathered data from 268 15 to 17 years old students who were enrolled in public secondary schools in St Kitts-Nevis - Caribe. Results: forty five percent of the students perceive that there is no risk if marijuana is smoked once or twice. One out of every 4 students felt that there is great risk if marijuana is used regularly. About half of the students felt that marijuana helps persons their age to cope with emotional difficulties. Students who have used marijuana have a low perception of the risks associated with marijuana use and are seven times more likely to continue using marijuana, if it were legal and they were 18 years of age. Conclusion: most of the students perceive that there is no personal harm associated with smoking marijuana. Students are not sure whether the benefits of using marijuana are greater than the risks. A noticeable proportion of students were unsure of the harms and benefits associated with marijuana use. It is recommended that suitable educational and preventative programmes be implemented in schools.

RESUMO Objetivo: esta investigação analisou a percepção dos adolescentes sobre os danos e benefícios do uso de maconha e como as mudanças regulatórias podem afetar sua intenção de usar maconha. Método: este estudo de levantamento transversal reuniu dados de 268 alunos de 15 a 17 anos matriculados em escolas públicas de ensino médio em St. Kitts-Nevis - Caribe.

Drinking patterns vary by gender, age and country-level income: Cross-country analysis of the International Alcohol Control Study.

INTRODUCTION AND AIMS: Gender and age patterns of drinking are important in guiding country responses to harmful use of alcohol. This study undertook cross-country analysis of drinking across gender, age groups in some high-and middle-income countries. DESIGN AND METHODS: Surveys of drinkers were conducted in Australia, England, Scotland, New Zealand, St Kitts and Nevis (high-income), Thailand, South Africa, Mongolia and Vietnam (middle-income) as part of the International Alcohol Control Study. Drinking pattern measures were high-frequency, heavier-typical quantity and higher-risk drinking. Differences in the drinking patterns across age and gender groups were calculated. Logistic regression models were applied including a measure of country-level income. RESULTS: Percentages of high-frequency, heavier-typical quantity and higher-risk drinking were greater among men than in women in all countries. Older age was associated with drinking more frequently but smaller typical quantities especially in high-income countries. Middle-income countries overall showed less frequent but heavier typical quantities; however, the lower frequencies meant the percentages of higher risk drinkers were lower overall compared with high-income countries (with the exception of South Africa). DISCUSSION AND CONCLUSIONS: High-frequency drinking was greater in high-income countries, particularly in older age groups. Middle-income countries overall showed less frequent drinking but heavier typical quantities. As alcohol use becomes more normalised as a result of the expansion of commercial alcohol it is likely frequency of drinking will increase with a likelihood of greater numbers drinking at higher risk levels.

Availability of alcohol: Location, time and ease of purchase in high- and middle-income countries: Data from the International Alcohol Control Study.

INTRODUCTION AND AIMS: Cross-country studies on alcohol purchasing and access are rare. We examined where and when people access alcohol to understand patterns of availability across a range of middle- and high-income countries. DESIGN AND METHODS: Surveys of drinkers in the International Alcohol Control study in high-income countries (Australia, England, Scotland, New Zealand and St Kitts and Nevis) and middle-income countries (Mongolia, South Africa, Peru, Thailand and Vietnam) were analysed. Measures were: location of purchase from on-premise and take-away outlets, proportion of alcohol consumed on-premise versus take-away outlets, hours of purchase, access among underage drinkers and time to access alcohol. RESULTS: On-premise purchasing was prevalent in the high-income countries. However, the vast majority of alcohol consumed in all countries, except St Kitts and Nevis (high-income), was take-away. Percentages of drinkers purchasing from different types of on-premise and take-away outlets varied between countries. Late purchasing was common in Peru and less common in Thailand and Vietnam. Alcohol was easily accessed by drinkers in all countries, including underage drinkers in the middle-income countries. DISCUSSION AND CONCLUSIONS: In nine out of 10 countries the vast majority of alcohol consumed was take-away. Alcohol was readily available and relatively easy for underage drinkers to access, particularly in the middle-income countries. Research is needed to assess the harms associated with take-away consumption including late at night. Attention is needed to address the easy access by underage drinkers in the middle-income countries which has been less of a focus than in high-income countries.

Policy-relevant behaviours predict heavier drinking and mediate the relationship with age, gender and education status: Analysis from the International Alcohol Control Study.

INTRODUCTION AND AIMS: To investigate behaviours related to four alcohol policy variables (policy-relevant behaviours) and demographic variables in relation to typical quantities of alcohol consumed on-premise in six International Alcohol Control study countries. DESIGN AND METHODS: General population surveys with drinkers using a comparable survey instrument and data analysed using path analysis in an overall model and for each country. MEASURES: typical quantities per occasion consumed on-premise; gender, age; years of education, prices paid, time of purchase, time to access alcohol and liking for alcohol advertisements. RESULTS: In the overall model younger people, males and those with fewer years of education consumed larger typical quantities. Overall lower prices paid, later time of purchase and liking for alcohol ads predicted consuming larger typical quantities; this was found in the high-income countries, less consistently in the high-middle-income countries and not in the low middle-income country. Three policy-relevant behaviours (prices paid, time of purchase, liking for alcohol ads) mediated the relationships between age, gender, education and consumption in high-income countries. DISCUSSION AND CONCLUSIONS: International Alcohol Control survey data showed a relationship between policy-relevant behaviours and typical quantities consumed and support the likely effect of policy change (trading hours, price and restrictions on marketing) on heavier drinking. The path analysis also revealed policy-relevant behaviours were significant mediating variables between the effect of age, gender and educational status on consumption. However, this relationship is clearest in high-income countries. Further research is required to understand better how circumstances in low-middle-income countries impact effects of policies.

Cross-country comparison of proportion of alcohol consumed in harmful drinking occasions using the International Alcohol Control Study.

INTRODUCTION AND AIMS: This study examines the proportion of alcohol markets consumed in harmful drinking occasions in a range of high-, middle-income countries and assesses the implications of these findings for conflict of interest between alcohol producers and public health and the appropriate role of the alcohol industry in alcohol policy space. DESIGN AND METHODS: Cross-sectional surveys were conducted in 10 countries as part of the International Alcohol Control study. Alcohol consumption was measured using location- and beverage-specific measures. A level of consumption defined as harmful use of alcohol was chosen and the proportion of the total market consumed in these drinking occasions was calculated for both commercial and informal alcohol. RESULTS: In all countries, sizeable proportions of the alcohol market were consumed during harmful drinking occasions. In general, a higher proportion of alcohol was consumed in harmful drinking occasions by respondents in the middle-income countries than respondents in the high-income countries. The proportion of informal alcohol consumed in harmful drinking occasions was lower than commercial alcohol. DISCUSSION AND CONCLUSIONS: Informal alcohol is less likely to be consumed in harmful drinking occasions compared with commercial alcohol. The proportion of commercial alcohol consumed in harmful drinking occasions in a range of alcohol markets shows the reliance of the transnational alcohol corporations on harmful alcohol use. This reliance underpins industry lobbying against effective policy and support for ineffective approaches. The conflict of interest between the alcohol industry and public health requires their exclusion from the alcohol policy space.

The Alcohol Environment Protocol: A new tool for alcohol policy.

INTRODUCTION AND AIM: To report data on the implementation of alcohol policies regarding availability and marketing, and drink driving, along with ratings of enforcement from two small high-income to three high-middle income countries, and one low-middle income country. METHOD: This study uses the Alcohol Environment Protocol, an International Alcohol Control study research tool, which documents the alcohol policy environment by standardised collection of data from administrative sources, observational studies and interviews with key informants to allow for cross-country comparison and change over time. RESULTS: All countries showed adoption to varying extents of key effective policy approaches outlined in the World Health Organization Global Strategy to Reduce the Harmful Use of Alcohol (2010). High-income countries were more likely to allocate resources to enforcement. However, where enforcement and implementation were high, policy on availability was fairly liberal. Key Informants judged alcohol to be very available in both high- and middle-income countries, reflecting liberal policy in the former and less implementation and enforcement and informal (unlicensed) sale of alcohol in the latter. Marketing was largely unrestricted in all countries and while drink-driving legislation was in place, it was less well enforced in middle-income countries. CONCLUSION: In countries with fewer resources, alcohol policies are less effective because of lack of implementation and enforcement and, in the case of marketing, lack of regulation. This has implications for the increase in consumption taking place as a result of the expanding distribution and marketing of commercial alcohol and consequent increases in alcohol-related harm.

The International Alcohol Control Study: Methodology and implementation.

INTRODUCTION AND AIMS: The International Alcohol Control (IAC) Study is a multi-country collaborative project to assess patterns of alcohol consumption and the impact of alcohol control policy. The aim of this paper is to report the methods and implementation of the IAC. DESIGN AND METHODS: The IAC has been implemented among drinkers 16-65 years in high- and middle-income countries: Australia, England, Scotland, New Zealand, St Kitts and Nevis, Thailand, South Africa, Peru, Mongolia and Vietnam (the latter four samples were sub-national). Two research instruments were used: the IAC survey of drinkers and the Alcohol Environmental Protocol (a protocol for policy analysis). The survey was administered via computer-assisted interview and the Alcohol Environmental Protocol data were collected via document review, administrative or commercial data and key informant interviews. RESULTS: The IAC instruments were readily adapted for cross-country use. The IAC methodology has provided cross-country survey data on key measures of alcohol consumption (quantity, frequency and volume), aspects of policy relevant behaviour and policy implementation: availability, price, purchasing, marketing and drink driving. The median response rate for all countries was 60% (range 16% to 99%). Where data on alcohol available for consumption were available the validity of survey consumption measures were assessed by calculating survey coverage found to be 86% or above. Differential response bias was handled, to the extent it could be, using post-stratification weights. DISCUSSION AND CONCLUSIONS: The IAC study will allow for cross-country analysis of drinking patterns, the relationship between alcohol use and policy relevant behaviour in different countries.

Support for alcohol policies among drinkers in Mongolia, New Zealand, Peru, South Africa, St Kitts and Nevis, Thailand and Vietnam: Data from the International Alcohol Control Study.

INTRODUCTION AND AIMS: A 2010 World Health Assembly resolution called on member states to intensify efforts to address alcohol-related harm. Progress has been slow. This study aims to determine the magnitude of public support for 12 alcohol policies and whether it differs by country, demographic factors and drinking risk (volume consumed). DESIGN AND METHODS: Data are drawn from seven countries participating in the International Alcohol Control Study which used country-specific sampling methods designed to obtain random, representative samples. The weighted total sample comprised 11 494 drinkers aged 16-65 years. RESULTS: Drinking risk was substantial (24% 'increased' risk and 16% 'high' risk) and was particularly high in South Africa. Support varied by alcohol policy, ranging from 12% to 96%, but was above 50% for 79% of the possible country/policy combinations. Across countries, policy support was generally higher for policies addressing drink driving and increasing the alcohol purchase age. There was less support for policies increasing the price of alcohol, especially when funds were not earmarked. Policy support differed by country, and was generally higher in the five middle-income countries than in New Zealand. It also differed by age, gender, education, quantity/frequency of drinking, risk category and country income level. DISCUSSION AND CONCLUSIONS: We found a trend in policy support, generally being highest in the low-middle-income countries, followed by high-middle-income countries and then high-income countries. Support from drinkers for a range of alcohol policies is extensive across all countries and could be used as a catalyst for further policy action.

Alcohol taxes' contribution to prices in high and middle-income countries: Data from the International Alcohol Control Study.

INTRODUCTION: Taxation is increasingly being used as an effective means of influencing behaviour in relation to harmful products. In this paper we use data from six participating countries of the International Alcohol Control Study to examine and evaluate their comparative prices and tax regimes. METHODS: We calculate taxes and prices for three high-income and three middle-income countries. The data are drawn from the International Alcohol Control survey and from the Alcohol Environment Protocol. Tax systems are described and then the rates of tax on key products presented. Comparisons are made using the Purchasing Power Parity rates. The price and purchase data from each country's International Alcohol Control survey is then used to calculate the mean percentage of retail price paid in tax weighted by actual consumption. RESULTS: Both ad valorem and specific per unit of alcohol taxation systems are represented among the six countries. The prices differ widely between countries even though presented in terms of Purchasing Power Parity. The percentage of tax in the final price also varies widely but is much lower than the 75% set by the World Health Organization as a goal for tobacco tax. CONCLUSION: There is considerable variation in tax systems and prices across countries. There is scope to increase taxation and this analysis provides comparable data, including the percentage of tax in final price, from some middle and high-income countries for consideration in policy discussion.
