Self-reported smoking and alcohol use among adolescents with intellectual disabilities

Smoking and e-cigarette use in young adults with disabilities

BACKGROUND

Tobacco use is closely linked to social and health inequalities, including economic vulnerability, morbidity, and premature death. Young adults with disabilities experience significant social and material hardships, which may be exacerbated by tobacco use. Limited research exists on smoking and e-cigarette use in this population. This study examines the prevalence of disability among young adults in Ireland, compares smoking and e-cigarette use between those with and without disabilities, identifies protective and risk factors, explores shared risk factors, and evaluates disability as an independent risk factor for smoking and e-cigarette use.

METHODS

We analysed weighted data from 4,729 20-year-olds in the Growing Up in Ireland Cohort '98 study who were present in Waves 1 (2008), 3 (2016), and 4 (2019). Current smoking, e-cigarette use, disability (excluding mental ill-health) and all other variables were assessed at Wave 4, while peer smoking data were drawn from Wave 3. Analyses were conducted using SPSS version 27.

RESULTS

18.1% of participants reported a disability, which was associated with significantly higher smoking (41.8% vs. 36.7%) and e-cigarette use (16.1% vs. 12.9%). Protective factors against both behaviours included being female (OR 0.87 for smoking, OR 0.57 for e-cigarettes), later smoking initiation (OR 0.35, OR 0.62), living in two-parent families (OR 0.83, OR 0.70), and physical activity (smoking only). Risk factors included having peers who smoked (OR 3.67 for smoking; OR 2.36 for e-cigarette use) and caregivers who smoked (OR 1.48, OR 1.48), being employed at age 20 (OR 1.58, OR 1.48), and social media engagement (smoking only). Young adults with disabilities were significantly more likely to experience risk factors (e.g., earlier smoking initiation, caregivers who smoked, one-parent families, employment) but were less likely to have peers who smoked or engage with social media. Disability was independently associated with a higher likelihood of smoking (by 54%) and e-cigarette use (by 36%) after adjusting for protective and risk factors.

CONCLUSION

Higher smoking and e-cigarette use in 20-year-olds with disabilities adds further inequality to their lives. Increased awareness, targeted surveys and focused prevention and therapeutic interventions are required to reduce inequalities in this population and hasten the tobacco endgame.

Comparing the prevalence of substance use disorders between persons with and without autism spectrum disorders

Recent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. This study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid enrollees with autism spectrum disorder (N = 388,426) and a random sample of enrollees without autism spectrum disorder (n = 745,699) and to examine whether this association differs across sex and age groups and changes after adjusting for co-occurring mental health conditions. We also examined how the association between autism spectrum disorder and substance use disorder is moderated by co-occurring non-autism spectrum disorder mental health conditions and by community-level social determinants of health by merging Medicaid Claims data with zip code-level US Census data on socioeconomic deprivation. By 2016, 7% of Medicaid beneficiaries with autism spectrum disorder and no intellectual disability had at least one substance use disorder diagnosis, up from 1.75% USD prevalence among enrollees with autism spectrum disorder (no intellectual disability) in 2012 Medicaid data. Individuals with autism spectrum disorder aged 30-64 years were at an elevated risk of cannabis and hallucinogen disorders; this risk is likely compounded by co-occurring mental health conditions, which affect a half of all individuals with autism spectrum disorder and only 23% of individuals without autism spectrum disorder. Research and policy implications are discussed in turn.Lay abstractRecent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. The present study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid beneficiaries with autism spectrum disorder and without autism spectrum disorder and to examine whether this association differs across sex and age groups and depends on mental health conditions besides autism. We also examined how the association between autism spectrum disorder and substance use disorder is moderated by co-occurring non-autism spectrum disorder mental health conditions and by community-level social determinants of health. For the latter purpose, Medicaid Claims data were merged with zip code-level US Census data on socioeconomic deprivation. Our analyses demonstrated that, by 2016, 7% of Medicaid enrollees with autism spectrum disorder and no intellectual disability had at least one substance use disorder diagnosis, up from 1.75% USD prevalence among enrollees with autism spectrum disorder (no intellectual disability) in 2012 Medicaid data. Individuals with autism spectrum disorder aged 30-64 years are at an elevated risk of cannabis and hallucinogen use disorders, while this risk is likely compounded by co-occurring mental health conditions, which affect a half of all individuals with autism spectrum disorder and only 23% of individuals without autism spectrum disorder. Research and policy implications are discussed in turn.

Disparities in Smoking and Heavy Drinking Behaviors by Disability Status and Age of Disability Onset: Secondary Analysis of National Health Interview Survey Data

OBJECTIVES

People with childhood-onset disabilities are living into adulthood, and the prevalence of smoking and illicit drug use among adults with disabilities is high. We evaluated the relationship between disability status and age of disability onset, current cigarette smoking status, and heavy alcohol drinking.

METHODS

We conducted a secondary data analysis of the National Health Interview Survey (NHIS), a US survey on illness and disability. Among 2020 NHIS participants aged 22-80 years (n = 28 225), we compared self-reported prevalence of current cigarette smoking and heavy alcohol drinking among those with and without disabilities and among those with childhood- versus adult-onset disabilities. We used adjusted logistic regression analysis to calculate the adjusted odds ratios (AORs) of current smoking and heavy alcohol drinking based on disability status and age of disability onset.

RESULTS

Compared with adults without disabilities, adults with disabilities were significantly more likely to report current smoking (23.5% vs 11.2%; P < .001) and significantly less likely to report heavy alcohol drinking (5.3% vs 7.4%; P = .001). The prevalence of these behaviors did not vary significantly by age of disability onset. In adjusted logistic regression models, adults with disabilities had significantly higher odds of current smoking (AOR = 1.76; 95% CI, 1.53-2.03) and similar odds of heavy alcohol drinking (AOR = 0.82; 95% CI, 0.65-1.04) compared with adults without disabilities. The odds of these health behaviors did not vary significantly by age of disability onset.

CONCLUSIONS

Adults with disabilities overall may be at high risk for these unhealthy behaviors, particularly smoking, regardless of age of disability onset. Routine screening and cessation counseling related to smoking and unhealthy alcohol use are important for all people with disabilities.

Association of Disability Status and Type With Binge Drinking and Prescription Opioid Misuse Among Adults From a 3-State Sample

BACKGROUND

Research examining at-risk substance use by disability status is limited, with little investigation into differences by disability type. We investigated binge drinking and prescription opioid misuse among adults with and without disabilities, and by type of disability, to inform need for assessment and intervention within these populations.

METHODS

Secondary analyses of adults who completed the disability, alcohol, and prescription opioid misuse items in the 2018 Ohio, Florida, or Nebraska Behavioral Risk Factor Surveillance System surveys (n = 28 341), the only states that included prescription opioid misuse in 2018. Self-reported disability status (yes/no) relied on 6 standardized questions assessing difficulties with: vision, hearing, mobility, cognition, self-care, and independent living (dichotomous, nonmutually exclusive, for each disability). Logistic regression models estimated the association of disability status and type with (1) past 30-day binge drinking and (2) past-year prescription opioid misuse. Additional models were restricted to separate subsamples of adults who: (a) currently drink, (b) received a past-year prescription opioid, and (c) did not receive a past-year prescription opioid.

RESULTS

One-third reported at least one disability, with mobility (19.5%), cognitive (11.5%), and hearing (10.2%) disability being the most common. Disability status was associated with lower odds of binge drinking (adjusted odds ratio [AOR] = 0.74, 95% confidence interval [CI] 0.68-0.80, P ≤ .01). However, among adults who currently drink, people with disabilities had higher odds of binge drinking (AOR = 1.11, 95% CI 1.01-1.22, P ≤ .05]. Disability was associated with higher odds of past-year prescription opioid misuse (AOR = 2.51, 95% CI 2.17-2.91, P ≤ .01).

CONCLUSIONS

Adults with disabilities had higher odds of prescription opioid misuse, and among adults who currently drink, higher odds for binge drinking were observed. The magnitude of the association between disability status and prescription opioid misuse was particularly concerning. Providers should be trained to screen and treat for substance use problems for people with disabilities.

Lifestyle modification interventions for adults with intellectual disabilities: systematic review and meta-analysis at intervention and component levels

BACKGROUND

Adults with intellectual disabilities (IDs) are susceptible to multiple health risk behaviours such as alcohol consumption, smoking, low physical activity, sedentary behaviour and poor diet. Lifestyle modification interventions can prevent or reduce negative health consequences caused by these behaviours. We aim to determine the effectiveness of lifestyle modification interventions and their components in targeting health risk behaviours in adults with IDs.

METHODS

A systematic review and meta-analysis were conducted. Electronic databases, clinical trial registries, grey literature and citations of systematic reviews and included studies were searched in January 2021 (updated February 2022). Randomised controlled trials and non-randomised controlled trials targeting alcohol consumption, smoking, low physical activity, sedentary behaviours and poor diet in adults (aged ≥ 18 years) with ID were included. Meta-analysis was conducted at the intervention level (pairwise and network meta-analysis) and the component-level (component network meta-analysis). Studies were coded using Michie's 19-item theory coding scheme and 94-item behaviour change taxonomies. Risk of bias was assessed using the Cochrane Risk of Bias (ROB) Version 2 and Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I). The study involved a patient and public involvement (PPI) group, including people with lived experience, who contributed extensively by shaping the methodology, providing valuable insights in interpreting results and organising of dissemination events.

RESULTS

Our literature search identified 12 180 articles, of which 80 studies with 4805 participants were included in the review. The complexity of lifestyle modification intervention was dismantled by identifying six core components that influenced outcomes. Interventions targeting single or multiple health risk behaviours could have a single or combination of multiple core-components. Interventions (2 RCTS; 4 non-RCTs; 228 participants) targeting alcohol consumption and smoking behaviour were effective but based on limited evidence. Similarly, interventions targeting low physical activity only (16 RCTs; 17 non-RCTs; 1413 participants) or multiple behaviours (low physical activity only, sedentary behaviours and poor diet) (17 RCTs; 24 non-RCTs; 3164 participants) yielded mixed effectiveness in outcomes. Most interventions targeting low physical activity only or multiple behaviours generated positive effects on various outcomes while some interventions led to no change or worsened outcomes, which could be attributed to the presence of a single core-component or a combination of similar core components in interventions. The intervention-level meta-analysis for weight management outcomes showed that none of the interventions were associated with a statistically significant change in outcomes when compared with treatment-as-usual and each other. Interventions with core-components combination of energy deficit diet, aerobic exercise and behaviour change techniques showed the highest weight loss [mean difference (MD) = -3.61, 95% credible interval (CrI) -9.68 to 1.95] and those with core-components combination dietary advice and aerobic exercise showed a weight gain (MD 0.94, 95% CrI -3.93 to 4.91). Similar findings were found with the component network meta-analysis for which additional components were identified. Most studies had a high and moderate risk of bias. Various theories and behaviour change techniques were used in intervention development and adaptation.

CONCLUSION

Our systematic review is the first to comprehensively explore lifestyle modification interventions targeting a range of single and multiple health risk behaviours in adults with ID, co-produced with people with lived experience. It has practical implications for future research as it highlights the importance of mixed-methods research in understanding lifestyle modification interventions and the need for population-specific improvements in the field (e.g., tailored interventions, development of evaluation instruments or tools, use of rigorous research methodologies and comprehensive reporting frameworks). Wide dissemination of related knowledge and the involvement of PPI groups, including people with lived experience, will help future researchers design interventions that consider the unique needs, desires and abilities of people with ID.

Patterns of Alcohol, Marijuana, and Tobacco Use Among U.S. Adolescents and Young Adults by Disability Status: 2015-2019

PURPOSE

To estimate the national prevalence of tobacco, marijuana, and alcohol use among U.S. adolescents (age 12-17) and young adults (aged 18-25; adolescents and young adults [AYAs]) with a disability and examine associations between disability and substance use from 2015 to 2019.

METHODS

Data from the 2015-2019 National Survey on Drug Use and Health were used to estimate the prevalence of tobacco, marijuana, and alcohol use among AYAs with disabilities. Modified Poisson regression models evaluated linear time trends in past-month substance use and estimated adjusted prevalence ratios (aPRs) for past-month cigarette, any tobacco, alcohol, and marijuana use.

RESULTS

Adolescents with any disability had a higher prevalence of past-month cigarette (aPR = 1.87; 95% CI 1.67-2.09), alcohol (aPR = 1.21; 95% CI 1.11-1.31), and marijuana use (aPR = 1.47; 95% CI 1.36-1.60) compared to those without disabilities. Cigarette smoking among adolescents decreased over this time period; however, the decline among adolescents without a disability was greater than those with any disability. Young adults with any disability had a higher prevalence of past-month cigarette (aPR = 1.42; 95% CI 1.35-1.48) and marijuana use (aPR = 1.39; 95% CI 1.34-1.45), but a lower prevalence of past-month alcohol use (aPR = 0.93; 95% CI 0.90-0.95) than those without disabilities. Alcohol use remained constant among young adults with any disability but decreased for those without disabilities.

DISCUSSION

Population-level disparities in cigarette and marijuana use exist in AYAs with disabilities. Future studies should identify strategies tailored to AYAs with disabilities to encourage smoking cessation and prevent cannabis use disorder.

Brief report: the prevalence of smoking and vaping among adolescents with/without intellectual disability in the UK

BACKGROUND

Few studies have investigated the prevalence of smoking among young people with/without intellectual disability. To date, no study has investigated the prevalence of vaping among young people with/without intellectual disability.

METHODS

Secondary analysis of data collected on 11 726 adolescents at age 14 years (2015) and from 9528 adolescents at age 17 years (2018) in the UK's Millennium Cohort Study.

RESULTS

The prevalence of smoking at ages 14 and 17 and of vaping at age 14 was similar among adolescents with and without intellectual disability. There was some evidence to suggest that at age 17, the prevalence of more frequent vaping was higher among girls with intellectual disability than among their female peers (5.2% vs. 1.6%, P < 0.05).

CONCLUSIONS

Further large-scale population-based research is required to determine the prevalence of smoking and vaping among people with intellectual disability. Evidence that at age 17, the prevalence of vaping was higher among girls with potential intellectual disability than among their female peers also warrants further investigation given the increasing evidence on the potential harm to health and well-being associated with vaping.

Tobacco Use in Adolescents With Disabilities: A Literature Review

The use of tobacco products by adolescents has greatly increased in recent years. Adolescents with disabilities have demonstrated higher instances of e-cigarette and tobacco use in relation to their peers without disabilities. Repercussions for e-cigarette and tobacco use increase negative physical and health implications and financial which ultimately will further the gap for individuals with disabilities over time. It is argued that adolescents with disabilities are more susceptible to begin using tobacco and remain using tobacco which can lead to further use of addictive substances. In this paper, the researcher explained the use of tobacco within the adolescent population, specifically for individuals with disabilities, the impact of tobacco use for individuals with disabilities, reviewed previous studies on tobacco use for adolescents with disabilities, points to the need for educational policy reform, and stated certain recommendations for mitigating tobacco use in adolescents with disabilities, which may result in positive future outcomes. The literature review indicated that the targeted interventions in schools or peer groups reduces tobacco use in adolescents with disabilities.

Investigating the relationship between high-risk behaviors and mental health in adolescents in Rabor city, Iran

OBJECTIVES

High-risk behaviors (HRBs) represent significant health threats for adolescents and significantly affect adolescents' mental health. Adolescents often engage in risky behaviors. The present study was conducted to investigate the relationship between high-risk behaviors (HRBs) and mental health in adolescents in Rabor.

CONTENT

The present study was a cross-sectional analytical study that was performed on 334 girl and boy students aged 12-18 years in Rabor city in 2021. In this study, adolescents answered high risk behaviors and mental health questionnaires. Data were analyzed using SPSS-26 software and the spearman correlation coefficient and linear regression analysis (univariate and multivariate analysis) were used to analyze the data.

SUMMARY AND OUTLOOK

In this study, the mean age was 15.25 ± 1.78. The findings indicate that smoking and hookah use were higher in boys than girls. Among the demographic variables, age and level of education had a positive and significant relationship with HRBs and mental health (p<0.05). The mean score of total mental health for all subjects was 12.83 ± 10.82. The variables of age, sex, marital status of parents, the number of children in the family, educational level, smoking, hookah, and alcohol have been determined as influential and facilitating factors in HRBs of adolescents. Father's literacy was considered as a facilitator and age variables, alcohol consumption and parents' marital status were considered as deterrents to mental health. The present study showed that the male gender is one of the risk factors for alcohol, smoking and other substances, the tendency to high-risk sexual behaviors, depression, and suicide in adolescents. Among the determinants of the tendency to HRBs in adolescents, psychological variables are of particular importance at the individual, social, and family levels. Good mental health can improve quality of life, while poor mental health can make it worse.

Understanding the effectiveness and underlying mechanisms of lifestyle modification interventions in adults with learning disabilities: protocol for a mixed-methods systematic review

BACKGROUND

Adults with learning disabilities have an increased disposition to unhealthy lifestyle behaviours which often occur simultaneously. Existing studies focus on complex interventions targeting unhealthy diet, physical inactivity, sedentary behaviour, smoking, and alcohol use to reduce health risks experienced. It is essential to understand how well these interventions work, what works, for whom, in what context and why. This study aims to investigate the effectiveness and underlying mechanisms of lifestyle modification interventions for adults with learning disabilities.

METHODS

This is a mixed-methods systematic review consisting of a network meta-analysis (NMA) and realist synthesis. Electronic databases (ASSIA, CINAHL, EMBASE, MEDLINE, and PsycINFO) will be searched from inception to 14 January 2021 with no language restriction. Additionally, trial registries, grey literature databases and references lists will be searched. Studies related to lifestyle modification interventions on the adult population (>18 years) with learning disabilities will be eligible for inclusion. Two independent researchers will screen studies, extract data and assess its quality and risk of bias using the Cochrane Collaboration's Risk of Bias Assessment Tool (RoB Version 2) and ROBINS-I. The strength of the body of evidence will be assessed based on the GRADE approach. The NMA will incorporate results from RCTs and quasi-experimental studies to estimate the effectiveness of various lifestyle interventions. Where appropriate, a component NMA (CNMA) will be used to estimate effectiveness. The realist synthesis will complement and explain the findings of NMA and CNMA by including additional qualitative and mixed-methods studies. Studies will be included based on their relevance to the programme theory and the rigour of their methods, as determined by quality appraisal tools appropriate to the study design. Results from both syntheses will be incorporated into a logic model.

DISCUSSION

The paucity of population-specific lifestyle interventions contributes to the challenges of behaviour change in adults with learning disabilities. This study will provide an evidence-base from which various stakeholders can develop effective interventions for adults with learning disabilities. The evidence will also help prioritise and inform research recommendations for future primary research so that people with learning disabilities live happier, healthier and longer lives.

Effectiveness of a mindfulness-oriented substance use prevention program for boys with mild to borderline intellectual disabilities: study protocol for a randomised controlled trial

BACKGROUND

Boys with mild to borderline intellectual disabilities (MBID) are at particular risk to drink in harmful ways once they start to consume alcohol. Interventions based on mindfulness have been proven to be effective in preventing substance use, but mostly for adults with MBID. A mindfulness oriented intervention targeting 11-17 years old boys will be tested in a randomised controlled trial. Study aim is to investigate the benefits of this new intervention compared to an active control condition within a 12 months follow-up.

METHODS

In this randomised controlled proof of concept study, 82 boys with MBID who consumed any alcohol during the last year will be randomised either to the 6 week mindfulness oriented intervention or the control group receiving a control intervention equal in dose and length. The intervention group undergoes mindfulness training combined with interactive drug education, while the control group completes a health training combined with the same education. In the intention-to-treat analysis the primary outcome is the self-reported delay of first post-intervention drunkeness within a 12 months follow-up time span, measured weekly with a short app-based questionnaire. Secondary outcome is the use of alcohol, tobacco and other drugs within 30 days post-intervention. Changes in neurobiological behavioural parameters, such as impulse control, reward anticipation, and decision making, are also investigated. Other secondary outcomes regard trait mindfulness, emotion regulation, psychopathological symptoms, peer networks, perceived stress, and quality of life. In addition, a prospective registry will be established to record specific data on the population of 11-17 year old boys with MBID without any alcohol experience.

DISCUSSION

This study offers the opportunity to gain first evidence of the effectiveness of a mindfulness-oriented program for the prevention of substance use for boys with MBID.

Risk-Taking and Delinquent Behaviors Among Youth with and without Intellectual Disabilities

INTRODUCTION

Youth with intellectual disabilities (ID) demonstrate higher rates of disruptive behavior disorders (DBDs) than youth with typical development (TD). DBDs such as oppositional defiant disorder (ODD) predict higher rates of delinquency during adolescence. Yet, few studies have examined risk-taking and delinquency among youth with ID.

METHODS

We used a self-report measure to determine whether 13-year-old youth with ID (n= 23) reported higher rates of risk-taking and delinquent behavior than their TD peers (n=77). We also examined whether or not youth had a previous diagnosis of ODD.

RESULTS

Our results suggest that youth with ID reported fewer rule-breaking and risk-taking behaviors than their TD peers. In contrast, youth with a previous diagnosis of ODD reported more of these behaviors.

CONCLUSION

Our results appear discrepant from previous studies, which find higher rates of risk-taking and delinquency among youth with ID. As such, we discuss the factors that may explain our discrepant results, including our definition and assessment of ID, and the age of our participants.

Smoking among adults with and without disabilities in the UK

Background

The health risks of cigarette smoking are well established. As a result, reducing cigarette smoking is a key concern for public health agencies. Little is known about rates of smoking among adults with disabilities.

Methods

Secondary analysis of data collected in Waves 2 and 7 of 'Understanding Society', an annual household panel study.

Results

Age and gender adjusted odds ratios (AORs) of adults with disabilities smoking increased significantly from 1.41 (1.33-1.49) in 2010-12 to 1.57 (1.45-1.70) in 2015-17 (P = 0.032). AORs of adults with disabilities smoking 20 or more cigarettes a day increased non-significantly from 1.83 (1.66-2.02) in 2010-12 to 1.90 (1.65-2.20) in 2015-17. These changes were evident for both men and women and across age groups. Additionally adjusting these estimates to take account of between group differences in socioeconomic position significantly reduced the AORs for both smoking outcomes. Changes over time in AORs reflected a more rapid decline in smoking among participants without a disability.

Conclusions

Adults with disabilities are more likely than their peers to smoke. Public health agencies and practitioners may wish to consider what reasonable adjustments may need to be made to policies and interventions to ensure that they are effective for adults with disabilities.

Tobacco product use and smoking frequency among US adults with intellectual and developmental disabilities

BACKGROUND

People with intellectual and developmental disabilities (IDD) have been overlooked in tobacco use research although they are likely to experience tobacco-related health disparities. This study examined tobacco product use and smoking frequency and amount among a sample of US Special Olympics athletes with IDD.

METHODS

Multiple regression analysis was used to test whether age, gender, body mass index, blood pressure, bone density, eating fruits and vegetables and family member tobacco use were correlated with the number of cigarettes smoked per day.

RESULTS

The sample of people with IDD who used tobacco (n = 501) were aged 18-75 (M = 33.37) and 76.4% were male. About 73.6% reported cigarette use only, 10.6% reported dual or poly use of cigarettes and other tobacco products (cigars, pipe, and chewing tobacco) and 15.8% reported using only tobacco products other than cigarettes. Men were more likely than women to use tobacco products other than cigarettes. Of the cigarette smokers, 79.6% were daily smokers, and their mean cigarettes per day was 10.08 (SD = 9.50). Special Olympics athletes who did not have low bone density and those who consumed fruits and vegetables less than daily reported higher numbers of cigarettes per day.

CONCLUSIONS

Although people with IDD are less likely to use tobacco than the general population, study results suggest that people with IDD who smoke cigarettes are just as likely as smokers in the general US population to smoke daily. Improving overall health behaviours may be important in helping smokers with IDD to reduce their tobacco use. Research is needed to understand longitudinal patterns of tobacco use and how to prevent tobacco use among people with IDD.

Alcohol, tobacco and cannabis use: Do students with mild-intellectual disability mimic students in the general population?

Education policies encourage inclusion of students with mild-intellectual disability (mild-ID) in community/school life. However, such policies potentially increase exposure to substance use. This article examines tobacco, alcohol and cannabis use among French students enrolled in special units for students with disabilities (ULIS) at mainstream junior high schools compared to those of general population of the equivalent age; and explores factors associated with substance use among ULIS students, known to present mostly mild-ID. In 2014, a questionnaire adapted from the international HBSC/WHO study was administered to 700 ULIS students (mean-age 14.2). Comparative data were gathered from 7023 junior high-school students (mean-age 13.6) in the general population. Among students <14 years-old, tobacco and alcohol use rates were similar between ULIS and general population. For students ≥14, alcohol use remained comparable, while tobacco and cannabis use were higher in general population. Among ULIS students, low perceived health/life satisfaction, divorced/separated parents and high perceived academic demands were associated with tobacco use. Bullying, not liking school very much and attending schools outside a deprived area were associated with alcohol use. Having had sexual intercourse and not perceiving one's health as excellent were associated with cannabis use. Having dated was associated with using all three substances.

Mild or borderline intellectual disability as a risk for alcohol consumption in adolescents - A matched-pair study

BACKGROUND

Studies that investigate the association between mild or borderline intellectual disability (MBID) and alcohol use in adolescents have not examined whether MBID is an independent risk factor for drinking.

AIM

It is important to examine whether MBID is a risk factor for alcohol consumption by controlling concomitant factors in a matched-pair design.

METHOD

Overall, 329 students from two schools for children with MBID self-reported their drinking behavior via questionnaires, and 329 students from regular schools were matched to this group by gender, age, family composition, and parental drinking behavior. Matched pairs were compared based on alcohol consumption and motivation to drink.

RESULTS

MBID is a protective factor, as disabled adolescents drink less on average. This effect is mainly due to larger proportions of youth with MBID who are abstinent. When male adolescents with MBID begin to drink, they are at an increased risk for intoxication and subsequent at-risk behaviors. Motivations to drink were explained by an interaction between MBID and consumption patterns.

CONCLUSIONS

For male adolescents with MBID, there appears to be an "all-or-nothing" principle that guides alcohol consumption, which suggests a need for special interventions for this group.

Health profiles and associated service use among adults with HIV and intellectual and developmental disabilities

OBJECTIVE(S)

Owing to the commonly held notion that individuals with intellectual and developmental disabilities (IDD) have low risk of HIV acquisition, we compared the prevalence of HIV infection among people with and without IDD. We also examined health status and health service use among the HIV-infected group.

DESIGN

Population-based cohort study using linked administrative health and social services databases.

METHODS

We compared HIV prevalence between Ontario adults with IDD (n = 64 008) and a 20% random sample of Ontario adults without IDD. Among the HIV-infected group, we compared adults with and without IDD in terms of comorbid chronic physical conditions and mental health disorders, as well as use of overall health services, mental health services, and HIV-specific services.

RESULTS

HIV prevalence per 100 000 population did not differ for adults with IDD [163.38 (95% confidence interval: 132.27, 199.6)] and without IDD [172.45 (95 confidence interval: 167.48, 177.53)]. Among the HIV-infected group, those with IDD had more comorbid chronic physical conditions and mental health disorders. They also had greater use of overall health services and mental health services. Likelihood of use of HIV-specific services also differed for those with and without IDD.

DISCUSSION

A similar prevalence of HIV among adults with and without IDD accentuates a need for strategies for individuals with IDD to be included in HIV prevention efforts. High prevalence of chronic physical and mental health comorbidity and health service use among the HIV-infected group with IDD highlight a need for comprehensive and coordinated treatment plans to optimize outcomes for this complex patient group.

Predictors of self-reported alcohol use and attitudes toward alcohol among 11-year-old British children with and without intellectual disability

BACKGROUND

Reducing harmful levels of alcohol consumption among children is an important public health concern internationally and in many high income countries. Little is known about levels and predictors of alcohol use among children with intellectual disability (ID).

METHOD

Secondary analysis of child self-report data at age 11 years collected in the UK's Millennium Cohort Study.

RESULTS

Children with ID were significantly more likely to: have used alcohol in the last 4 weeks; to have had five or more alcoholic drinks on one occasion; to have had five or more alcoholic drinks or been intoxicated on one occasion; to have more positive attitudes about the psychological and social benefits of drinking; and to have less negative attitudes about the social and physical costs of drinking. Potentially harmful levels of drinking (intoxication or 5+ alcoholic drinks on one occasion) among children with ID were associated with child smoking, having friends who use alcohol, reporting that drinking makes it easier to make friends, and reporting that drinking reduces worrying. Children with ID accounted for 9% of all children with potentially harmful levels of drinking.

CONCLUSION

Public health interventions to reduce potentially harmful drinking among children in general must recognise that children with ID are a potentially high risk group and ensure that interventions are appropriately adjusted to take account of their particular needs and situation. Future research in this area is needed to untangle the causal pathways between attitudes toward alcohol and alcohol use among children with ID and the extent to which levels of alcohol use and predictors of alcohol use may be moderated by severity of ID.

Tobacco and Alcohol Use in People With Mild/Moderate Intellectual Disabilities: Giving Voice to Their Health Promotion Needs

BACKGROUND

Concerns have been raised about the use/misuse of tobacco and alcohol by people with mild/moderate intellectual disabilities. Aiming to address an identified gap in the current evidence base, this study sought to gain an understanding of the tobacco- and alcohol-related health promotion needs of this client group.

METHODS

Informed by the principles of social cognitive theory, data were collected using focus group and telephone interviews. Participants were 16 people with intellectual disabilities, two family carers and 15 health and social care professionals. Data were analysed using the Framework approach.

FINDINGS

Four themes were described: being like others; social and emotional influences; understandings, misunderstandings and learning from experience; and choices and challenges. Reasons for smoking and drinking alcohol echoed those of the general population; however, health promotion needs were more complex (e.g. linked to problems with consequential thinking; low levels of self-efficacy).

CONCLUSION

This article provides insight into the tobacco- and alcohol-related health promotion needs of people with intellectual disabilities. There is a need for integrated service provision that addresses both personal and environmental influences on behaviour.

Exposure to second hand tobacco smoke at home and child smoking at age 11 among British children with and without intellectual disability

BACKGROUND

The exposure of children to second hand tobacco smoke (SHS) is a well-established risk factor for a range of adverse health conditions in childhood and later life. Little is known about the extent to which children with intellectual disability (ID) may be exposed to SHS. Our aim in this study was to estimate the risk of childhood exposure to SHS and early experience of smoking among children with and without ID in a nationally representative cohort of British children.

METHOD

Secondary analysis of data extracted from the UK's Millennium Cohort Study, a nationally representative sample of over 18,000 UK children born 2000-2002.

RESULTS

Children with ID are significantly more likely than their peers to be exposed to SHS and to have themselves experimented with smoking by age 11. Controlling for between-group differences in socio-economic position eliminated the increased risk of exposure to SHS and significantly attenuated, but did not eliminate, increased risk of experimenting with smoking by age 11.

CONCLUSIONS

Levels of exposure to SHS among children with ID are typical of those of families of children without ID living in similar socio-economic circumstances. The results lend no support to the hypothesis that increased rates of parental smoking may be associated with any additional 'burden of care' experienced by parents of children with ID. Nevertheless, it will be important to ensure that evidence-based interventions to reduce exposure to SHS are tailored to the specific needs of families supporting children with ID (e.g. through the provision of disability-friendly child care arrangements).

Obesity and health behaviours of British adults with self-reported intellectual impairments: cross sectional survey

BACKGROUND

People with intellectual disability have significantly higher age-adjusted rates of mortality and morbidity (including obesity) than their non-disabled peers. They are also significantly less likely to be physically active.

METHODS

Secondary analysis of de-identified cross-sectional data from the first two waves of Understanding Society, a new longitudinal study focusing on the life experiences of UK citizens. Interviews were undertaken with 50,994 individuals aged 16 and over in Wave 1 and 54,585 in Wave 2. Of these, 520 participants age 16-49 (1.8% of the unweighted age-restricted sample) were identified at either Wave 1 or Wave 2 as having self-reported intellectual impairments.

RESULTS

British adults with self-reported intellectual impairments have higher rates of obesity, inactivity, tobacco and alcohol use and poorer nutrition than their non-disabled peers. Adjusting risk estimates for between group differences in age, gender and exposure to material hardship indicated that a significant proportion of their increased risk of obesity, tobacco use and poorer nutrition may be attributable to their poorer living conditions (rather than their self-reported intellectual impairments per se).

CONCLUSIONS

People with intellectual disabilities should begin to be regarded as a 'vulnerable' group in the context of public health policy and practice.

Gesundheitsförderung von Menschen mit intellektueller Behinderung

Zahlreiche Publikationen belegen, dass die Gesundheit von Menschen mit intellektueller Behinderung (IB) für Krankheiten und Störungen anfälliger ist als die der Allgemeinbevölkerung. Zudem sind bestimmte Risikoverhaltensweisen (z. B. schlechte Ernährung und wenig Bewegung) häufiger bei dieser Personengruppe zu finden. Trotz der sensibleren Gesundheitssituation steht die gesundheitspsychologische Forschung für Menschen mit IB noch am Anfang. Für diesen Überblicksartikel wurde Fachliteratur über Menschen mit IB nach gesundheitspsychologischen Konzeptionen durchsucht und bestehende Forschungsarbeiten analysiert. Des Weiteren wurden rezente Gesundheitsmodelle sowie Kontinuitäts- und Stadienmodelle für die Allgemeinbevölkerung und ihre einzelnen Bestandteile hinsichtlich ihrer Übertragbarkeit auf diese spezielle Population untersucht. Eine Generalisierung von Gesundheitsmodellen der Allgemeinbevölkerung auf die Gruppe von Menschen mit IB erscheint aus verschiedenen Gründen problematisch. So erweist sich z. B. die Erfassung einzelner Bestandteile durch ihre Abstraktheit als zu komplex für Menschen mit IB. Dieses und ähnliche Forschungshindernisse werden in diesem Artikel besprochen. Diese genaue Analyse hilft jedoch notwendige Kriterien für die Entwicklung eines theoretischen Gesundheitsmodells speziell für Menschen mit IB zu erstellen. Schlussendlich werden relevante Modellbausteine für Menschen mit IB, die auf den präsentierten Forschungsergebnissen aufbauen, vorgestellt und diskutiert. Schließlich werden zukünftige Forschungsfragen erörtert.

Commentary: Childhood exposure to environmental adversity and the well-being of people with intellectual disabilities

People with intellectual disabilities have poorer health than their non-disabled peers. They are also more likely to be exposed to a wide range of environmental adversities in childhood. Research undertaken in the general population has demonstrated that exposure to environmental adversity in childhood can have an adverse impact on health and well-being across the life course. Recently, research in this area has added new breadth and depth to our understanding of: (1) the extent to which cumulative exposure to environmental adversities across the life course, but especially in early childhood, can reduce health and well-being; (2) the social, psychological and biological mediating pathways through which environmental adversities may impair health; (3) the processes associated with resilience and vulnerability in the face of exposure to adversity; and (4) the social significance of these effects in accounting for the magnitude of the inequalities in health that are apparent both between and within populations. This new knowledge is making a significant contribution to the development of social policies that seek to combine health gain with the reduction in health inequalities. This paper attempts to apply this knowledge to research aimed at understanding and improving the health and well-being of people with intellectual disabilities.

Tobacco and alcohol-related interventions for people with mild/moderate intellectual disabilities: a systematic review of the literature

BACKGROUND

The behavioural determinants of health among people with mild/moderate intellectual disabilities (ID) are of increasing concern. With the closure of long-stay institutions, more people with ID are living in the community. As they lead more ordinary and less restricted lives, people with ID may be exposed to social and environmental pressures that encourage them to adopt behaviours that impact negatively on their health. Levels of smoking and alcohol consumption in this client group are of particular concern.

METHODS

We undertook a mixed method review of the literature, aiming to assess the Feasibility, Appropriateness, Meaningfulness and Effectiveness (FAME) of interventions designed to address the use of tobacco and/or alcohol in people with mild/moderate ID. Key electronic databases were searched (e.g., Medline, Cochrane Register of Controlled Trials, PsycINFO) from 1996 to 2011. The search was developed using appropriate subject headings and key words (e.g., intellectual disability, tobacco use, alcohol drinking, health promotion). On completion of the database searches, inclusion/exclusion criteria, based on an adaptation of the PICO framework (Population, Intervention, Comparison, Outcomes), were applied. Methodological quality was assessed using a seven-point rating scale.

RESULTS

Database searches identified 501 unique records, of which nine satisfied the inclusion criteria. Four focused on tobacco, three on alcohol and two on both tobacco and alcohol. Located in the U.K., the U.S.A. and Australia, the studies aimed to increase knowledge levels and/or change behaviour (e.g., to encourage smoking cessation). One was a randomised controlled trial, one a quasi-experiment and the others were before and after studies and/or case studies. Methodological quality was poor or moderate. The combined studies had a sample size of 341, with ages ranging from 14 to 54 years. The interventions were delivered by professionals (e.g., in health, social care, education) during sessions that spanned a period of three weeks to one academic year. The studies highlighted a number of important issues linked to the appropriateness of interventions for this client group (e.g., use of pictures, quizzes, role play, incentives); however, in the majority of cases the interventions appeared to lack a theoretical framework (e.g., behaviour change theory). The appropriateness of the outcome measures for use with this client group was not tested. One study discussed feasibility (teachers delivering lessons on alcohol and tobacco) and only one was informative in terms of effectiveness, i.e., increasing knowledge of the health and social dangers of smoking and excessive alcohol consumption.

CONCLUSIONS

This review is the first to systematically collate evidence on tobacco and alcohol-related interventions for people with ID. While there is currently little evidence to guide practice, the review delivers clear insights for the development of interventions and presents a strong case for more robust research methods. In particular there is a need to test the effectiveness of interventions in large-scale, well-designed trials and to ensure that outcome measures are developed/tailored appropriately for this client group.

Cognitive biases in individuals with mild to borderline intellectual disability and alcohol use-related problems

The primary aim of the present pilot study was to examine cognitive biases in individuals with mild to borderline ID and alcohol use-related problems. Participants (N=57) performed the approach avoidance task, picture rating task and visual dot probe task, which was combined with eye-tracking methodology. They were admitted to a forensic setting and were all abstinent and undergoing treatment at the time of testing. Three groups were formed based on the severity of alcohol use-related problems as measured by the AUDIT. In line with the expectations, no differences were found between participants based on the severity of their alcohol use-related problems. In addition, three groups were formed based on IQ to assess the relationship between IQ and the strength of the cognitive biases. There were also no differences between individuals with mild or borderline ID and individuals with (below) average IQ on any of the variables. It is concluded that computer tasks such as these can be used in individuals with mild to borderline ID. As the results suggest no influence of IQ on the strength of cognitive biases, this study opens up new opportunities for future research on the application of measuring cognitive biases in screening, diagnosing and treating individuals with mild to borderline ID and alcohol use-related problems.

Alcohol and intellectual disability: personal problem or cultural exclusion?

The small number of studies on alcohol use among adults with intellectual disabilities shows their usage is significantly less than average, with very high levels of abstinence. Despite this, the literature focuses almost to exclusion on the very small number of people who do have problems, and neglects to question the possible reasons for this differential pattern of consumption. This article reviews the extant literature, showing that it constructs an inherently pathological view of drinking in people with intellectual disabilities, framing it entirely within a discourse of risk and as a personal behaviour, rather than as a social and cultural one. As a counter to this perspective, the article opens up new lines of exploration around the significance of abstinence, why it might occur to such a high degree and whether, in fact, it might itself be and also point towards the cultural exclusion of people with intellectual disabilities.

Assessing the health, functional characteristics, and health needs of youth attending a noncategorical transition support program

PURPOSE

To assess the health, functional characteristics, and health care service needs of youth and young adults with special health care needs attending a comprehensive, noncategorical transition program.

METHODS

A self-administered survey was developed from national health surveys and clinical experience to assess concepts identified as important for successful transition to adulthood. Surveys were mailed to 198 parents of youth and young adults with special health care needs attending the transition clinic. Parents were asked about the youth's health, functional status, and health care services needed. The clinical database provided demographic and patient health characteristics. Results were compared against the 2005-2006 National Survey of Children with Special Health Care Needs.

RESULTS

Forty-four percent of surveys were returned. Average age of youth was 17.5 (11-22) years old and diagnoses included cerebral palsy (36%), spina bifida (10%), developmental delay or Down syndrome (17%), and autism (6%). Most youth needed assistance with personal care (69%) and routine needs (91%) and used assistive devices (59%). Compared with the 2005-2006 National Survey of Children with Special Health Care Needs, parents reported higher needs for all services except mental health care and tobacco or substance use counseling. Forty three percent reported at least one unmet health need. Few parents reported the need for counseling on substance use (1%), sexual health screening (16%), nutrition (34%), and exercise (41%).

CONCLUSIONS

Youth attending our transition program had more functional limitations, poorer reported health status, different diagnosis distribution, and higher levels of needed health services. Few parents identified needs for other recommended adolescent preventive services. Transition programs should assess patient health characteristics and service needs to design effective patient-centered services.

Healthy lifestyles for adults with intellectual disability: knowledge, barriers, and facilitators

BACKGROUND

People with intellectual disability (ID) are more likely to have health problems than people without disability. Little previous research has investigated health from the perspective of the people with ID themselves. We aimed to focus on what people with ID understand being healthy to mean and what their experiences are of healthy lifestyles.

METHOD

Semistructured interviews were conducted with 13 adults with ID to ask them about their health and healthy lifestyles. Data were analysed thematically.

RESULTS

Participants demonstrated understanding of what it means to be healthy, have a healthy diet, the dangers of substance misuse, and the benefits of exercise. Participants demonstrated some knowledge about rationales for engaging in healthy behaviours. The idea of moderation was raised, along with barriers and facilitators to engaging in a healthy lifestyle.

CONCLUSIONS

Findings suggest that people with ID demonstrate some understanding of what constitutes being healthy and are aware of healthy lifestyles, the consequences of unhealthy behaviours, and of the need for moderation.

Problematic alcohol use and mild intellectual disability: standardization of pictorial stimuli for an alcohol cue reactivity task

The present study focused on the first step in developing a cue reactivity task for studying cognitive biases in individuals with mild to borderline intellectual disability (ID) and alcohol use-related problems: the standardization of pictorial stimuli. Participants (N=40), both with and without a history of alcohol use-related problems and varying in IQ, were admitted to a forensic setting and were all abstinent. They were asked to rate familiarity, complexity, valence and attractiveness of pictures portraying both alcoholic and non-alcoholic beverages. There was a tendency to rate non-alcoholic beverages as more pleasant and attractive than alcoholic beverages. In participants with mild to borderline ID, this difference reached statistical significance, even when controlling for alcohol use-related problems in the past. The overall result of the study is a large database of 255 pictures portraying both alcoholic and non-alcoholic beverages that will be used to validate an implicit measure of cognitive biases for alcohol in individuals with mild to borderline ID.

Substance abuse among individuals with intellectual disabilities

Individuals with disabilities are a growing population that confronts multiple disadvantages from social and environmental determinants of health. In particular, the 7-8 million people in the U.S. with an intellectual disability (ID) suffer disproportionately from substance use problems, largely because of a lack of empirical evidence to inform prevention and treatment efforts for them. Although available research could inform future research efforts, studies are scattered across disciplines with the last review synthesizing findings written more than five years ago. To consider more recent findings with earlier works, PubMed, PsychINFO, and Google Scholar were searched and produced 37 peer-reviewed texts across multiple disciplines, 15 from 2006 or later. While the prevalence of alcohol and illicit drug use in this population are low, the risk of having a substance-related problem among ID substance users is comparatively high. Gaps in the research and population subgroups that warrant special attention are identified, such as individuals with borderline and mild ID, individuals with co-occurring mental illness, and individuals who are incarcerated. Compared with substance abusers without ID, ID substance abusers are less likely to receive substance abuse treatment or remain in treatment. Research is needed to better gauge the magnitude of substance use problems, identify prevention strategies, and specify treatment components that meet the unique needs of individuals with ID.

Health inequalities experienced by children and young people with intellectual disabilities: a review of literature from the United Kingdom

This literature review aimed to synthesize evidence on the prevalence and determinants of health conditions and impairments among children and young people with intellectual disability in the United Kingdom. Several databases were systematically searched for studies conducted with children under the age of 18 living in the United Kingdom and published in 2010-11. Evidence from a 2002 and a 2010 literature review on health inequalities among individuals of all ages with intellectual disability was also reviewed. We conclude there is an increased prevalence of a number of health conditions and impairments among children with intellectual disability and evidence that these health inequalities are associated with several preventable environmental determinants.

Effects of a mindfulness-based smoking cessation program for an adult with mild intellectual disability

Smoking is a major risk factor for a number of health conditions and many smokers find it difficult to quit smoking without specific interventions. We developed and used a mindfulness-based smoking cessation program with a 31-year-old man with mild intellectual disabilities who had been a smoker for 17 years. The mindfulness-based smoking cessation program consisted of three components: intention, mindful observation of thoughts, and Meditation on the Soles of the Feet. A changing-criterion analysis showed that this man was able to fade his cigarette smoking from 12 at baseline to 0 within 3 months, and maintain this for a year. Follow-up data, collected every 3 months following the maintenance period, showed he was able to abstain from smoking for 3 years. Our study suggests that this mindfulness-based smoking cessation program merits further investigation.

Prevalence and influences on self-reported smoking among adolescents with mild learning disabilities, attention deficit hyperactivity disorder, and their typically developing peers

Many adolescents take up the smoking habit despite its well-documented adverse health effects. This study explores the prevalence and influences on smoking among 89 adolescents with mild learning disabilities, 108 with attention deficit hyperactivity disorder (ADHD), and 124 typically developing peers aged 12-16 years. All the participants were attending mainstream secondary schools and they were asked to complete a self-report questionnaire on smoking. It was found that adolescents with ADHD smoked more than adolescents with mild learning disabilities, who in turned smoked more than adolescents not diagnosed with any disability. More adolescents with ADHD reported that the majority of their friends smoked and they were less well informed about the health effects of smoking. No differences were identified between the three groups in terms of the smoking behaviour of their parents and the perceived attitudes of their parents and friends towards smoking. Findings are discussed and suggestions are made for further research.

Listening to people with intellectual disabilities who misuse alcohol and drugs

There is a dearth of research that has explored alcohol/drug use and misuse by people with intellectual disabilities. The aims of the present study were twofold: (1) to examine the insights of 10 people with intellectual disabilities into the reasons why they may misuse alcohol or drugs, and what impact this behaviour may have on them; and (2) to explore the services that they receive. Ten individuals with intellectual disabilities who were deemed to be misusing alcohol/drugs were purposively selected and interviewed. One overarching theme of the reasons for such misuse was labelled as 'self-medicating against life's negative experiences'. This was divided into two sub-themes: 'psychological trauma' and 'social distance from the community'. All the participants reported that their main source of support came from intellectual disability services, acting in both educational and liaison roles. Although seven of the individuals were referred to mainstream addiction services, they perceived this service as negative. In order to address these underlying problems, better access to a wider range of specialist services is required. Intellectual disability and mainstream addiction service providers also need to be more effective in the prevention and treatment of substance misuse by employing techniques such as motivational interviewing.

Poverty and people with intellectual disabilities

Epidemiological studies have consistently reported a significant association between poverty and the prevalence of intellectual disabilities. The available evidence suggests that this association reflects two distinct processes. First, poverty causes intellectual disabilities, an effect mediated through the association between poverty and exposure to a range of environmental and psychosocial hazards. Second, families supporting a child with intellectual disabilities and adults with intellectual disabilities are at increased risk of experiencing poverty due to the financial and social impact of caring and the exclusion of people with intellectual disabilities from the workforce. It is likely that the association between poverty and intellectual disabilities accounts in part for the health and social inequalities experienced by people with intellectual disabilities and their families. Implications for policy and practice are discussed in relation to the funding of services for people with intellectual disabilities and preventative approaches to addressing the health and social inequalities experienced by people with intellectual disabilities and their families.

Young people with Down syndrome: a preliminary investigation of health knowledge and associated behaviours

BACKGROUND

Adults with intellectual disability have a range of significant health problems. If they are to live independently, they need to engage in behaviours that are health promoting, as well as avoiding behaviours that might directly lead to ill health. There is very little research about health-related knowledge and behaviour in this group.

METHOD

A group of 38 adolescents with Down syndrome (DS) and their families participated in this study. A semi-structured interview and a series of tasks were used to collect data on individuals' health knowledge and behaviour relating to 4 aspects of health: hygiene, substance use, exercise and healthy eating.

RESULTS

While the majority of young people demonstrated some awareness of basic hygiene, they were not yet at the level where these behaviours could be guaranteed to occur without parental support. Knowledge about substance use, exercise and healthy food was generally poor.

CONCLUSION

Knowledge of most aspects of health assessed in this study was poor and pointed to a gap in the preparation of these young people for independent living.

Alcohol-related problems in adolescents and adults with intellectual disabilities

PURPOSE OF REVIEW

Alcohol is widely available and one of the most commonly used psychoactive substances. This review examined the recent literature for empirical research addressing the cause, prevalence and treatment of alcohol-related problems in adolescents and adults with intellectual disabilities.

RECENT FINDINGS

Adequate controlled research has not been conducted, and most of the studies were epidemiological and inconclusive. Despite the high variation in the reported prevalence in alcohol use and misuse rates, most published studies document that adolescents and adults with intellectual disabilities consume alcohol at substantially lower rates than the general population. Few treatment interventions have been reported, but limitations in the study design outline the emphasis for future research.

SUMMARY

Alcohol misuse affects the physical and mental health of people with intellectual disabilities, leading to behavioural and social difficulties. Assessment and treatment of alcohol-related problems pose ethical considerations. Uncertainty surrounds the ability of alcohol services, and services for individuals with intellectual disabilities respectfully, to meet the needs of this population. Modification of existing treatment approaches, further staff training and development of liaison approach between alcohol services and services for people with intellectual disabilities need further evaluation of their effectiveness.

An exploration of substance misuse in people with intellectual disabilities

BACKGROUND

Little is known about the characteristics of people with intellectual disabilities (IDs) who misuse substances and how such problems impinge upon their well-being. The aim of this paper is to describe how alcohol and drugs affect the health of people with IDs.

METHODS

A questionnaire was forwarded to all the community ID teams and mainstream addiction teams across Northern Ireland: 67 substance users with IDs and substantial substance-related problems were identified.

RESULTS

Alcohol was found to be the main substance to be misused, with one-fifth of the substance users also found to be using a combination of illicit drugs and/or prescribed medication. Nearly three-quarters of the sample were found to be hazardously using alcohol for more than 5 years. Being male and young, having a borderline/mild ID, living independently and having a mental health problem were found to be risk factors for developing a 'substance related problem'. Various problematic behaviours were identified, including aggression, erratic mood changes, sexual exploitation, difficulties in maintaining relationships and loss of daily routine.

CONCLUSIONS

The findings of this study suggest that greater emphasis needs to be placed upon the early identification of this hidden population by primary and secondary healthcare personnel, and also ID personnel. Such early identification may also diminish the long-established patterns of use and associated related-behaviours that have been reported within this paper.

A review of substance use research among those with mental retardation

This article reviews research conducted on the cigarette, alcohol, and illicit drug use of adolescents and adults with mental retardation (MR). The majority of the research related to substance use conducted on this population has been limited to surveys. Overall, results of these studies suggest that, although substance use is slightly lower among those with MR than among nondisabled comparison groups, it is nonetheless a problem for many individuals. This research is reviewed and a discussion of both the general and specific flaws of these studies follows. Further, the examination of education, prevention, and treatment programs for this population has been overlooked, indicating that individuals with MR are likely not receiving the services most appropriate for them. The article concludes with a discussion of several topics that need to be addressed in future studies, including research on potential best practices in the overlooked areas of substance abuse interventions.

Self-reported anti-social behaviour: prevalence and risk factors amongst adolescents with and without intellectual disability

BACKGROUND

Research has suggested increased risk of anti-social behaviour amongst individuals with intellectual disability (ID).

METHODS

This study reports the results of a secondary analysis of data relating to self-reported anti-social behaviour, obtained from the 1999 Office for National Statistics (ONS) study of the mental health of children and adolescents in Great Britain. Self-report data from 4174 adolescents was available. Within this group, a sub-group of 98 adolescents with ID was identified. Data covered a variety of sub-types of anti-social behaviour.

RESULTS

Comparisons of individuals with ID and those without ID indicated a significantly higher prevalence of a number of types of self-reported anti-social behaviour in the ID sample. Further analyses indicated however, that these between group differences were accounted for by the higher rates of social deprivation and child mental health problems among the ID sample.

CONCLUSIONS

Rather than ID per se being associated with increased rates of anti-social behaviour, adolescents with ID may be more likely to experience risk factors (lower socio-economic status and mental health problems) known to be associated with anti-social behaviour. The clinical implications of this and possible future directions for research are discussed.
