Predictors of substance use among vulnerable adolescents in five cities: findings from the well-being of adolescents in vulnerable environments study

Using Interactive Television Instruction (ITV) to Reduce the Propensity to Engage in Substance Abuse and Drug Trafficking Among Vulnerable Adolescents in Nigeria

This study examined the impact of ITV intervention on reduction in the propensity to abuse substances and engage in drug trafficking. The researcher conducted this study using an experiment of 517 vulnerable adolescents aged 10-19 years. The participants were randomly assigned to control (n = 258) and treatment (n = 259) groups. The researchers found a significant main effect of treatment conditions on reduction in the propensity to engage in substance abuse and drug trafficking among vulnerable adolescents. That is, before the intervention, there was no significant statistical difference between the control and treatment groups on the propensity to engage in substance abuse and drug trafficking. However, vulnerable children who received the intervention reported a significant reduction in propensity after the intervention. The results highlight the usefulness of ITV as a behaviour change strategy for vulnerable children.

Substance use patterns in an adolescent psychiatric unit in Johannesburg, South Africa

Background

Substance use among adolescents carries a significant public health and socioeconomic burden with potential long-term consequences for the adolescent substance user (SU). Adolescents with mental health challenges are vulnerable to substance use and substance use worsens outcomes in this population.

Aim

This study aimed to describe the substance use patterns among inpatients admitted to a specialised tertiary adolescent inpatient unit in Johannesburg over a 4-year period.

Setting

This study was conducted at the Tara H. Moross Centre (Tara Hospital), in Johannesburg in the Gauteng province of South Africa.

Methods

This was a retrospective comparative record review of all patients admitted to the adolescent unit over the 4 years.

Results

A lifetime history of substance use was documented in 44.1% (n = 52) of the 118 patient's records included in the final analysis. Cannabis was the most frequently used substance (n = 36, 69.2%). There were significant differences between the SU and substance nonuser groups regarding family structure (p = 0.012), family history of substance abuse (p = 0.046) and conflict within the family (p < 0.001).

Conclusion

The high prevalence of substance use in this sample demonstrates the dual burden of mental health disorders and substance use in an adolescent treatment programme in Johannesburg. Primary caregiver burden and relational difficulties within the family unit should be observed for planned multidisciplinary interventions.

Contribution

The findings of this review provide an update on the pattern and prevalence of substance use among this adolescent mental healthcare user group, highlighting potential therapeutic targets.

The influence of depressive symptoms and school-going status on risky behaviors: a pooled analysis among adolescents in six sub-Saharan African countries

BACKGROUND

Evidence from sub-Saharan Africa (SSA) regarding risky behaviors among adolescents remains scarce, despite the large population (approximately 249 million out of 1.2 billion globally in 2019) of adolescents in the region. We aimed to examine the potential influence of depressive symptoms and school-going status on risky behaviors among adolescents in six SSA countries.

METHODS

We used individual cross-sectional data from adolescents aged 10-19 based in eight communities across six SSA countries, participating in the ARISE Network Adolescent Health Study (N = 7,661). Outcomes of interest were cigarette or tobacco use, alcohol use, other substance use, getting into a physical fight, no condom use during last sexual intercourse, and suicidal behavior. We examined the proportion of adolescents reporting these behaviors, and examined potential effects of depressive symptoms [tertiles of 6-item Kutcher Adolescent Depression Scale (KADS-6) score] and school-going status on these behaviors using mixed-effects Poisson regression models. We also assessed effect modification of associations by sex, age, and school-going status.

RESULTS

The proportion of adolescents reporting risky behaviors was varied, from 2.2% for suicidal behaviors to 26.2% for getting into a physical fight. Being in the higher tertiles of KADS-6 score was associated with increased risk of almost all risky behaviors [adjusted risk ratio (RR) for highest KADS-6 tertile for alcohol use: 1.70, 95% confidence interval (95% CI): 1.48-1.95, p < 0.001; for physical fight: 1.52, 95% CI: 1.36-1.70, p < 0.001; for suicidal behavior: 7.07, 95% CI: 2.69-18.57, p < 0.001]. Being in school was associated with reduced risk of substance use (RR for alcohol use: 0.73, 95% CI: 0.53-1.00, p = 0.047), and not using a condom (RR: 0.81, 95% CI: 0.66-0.99, p = 0.040). There was evidence of modification of the effect of school-going status on risky behaviors by age and sex.

CONCLUSION

Our findings reinforce the need for a greater focus on risky behaviors among adolescents in SSA. Addressing depressive symptoms among adolescents, facilitating school attendance and using schools as platforms to improve health may help reduce risky behaviors in this population. Further research is also required to better assess the potential bidirectionality of associations.

Risk factors for alcohol use among adolescents: The context of township high schools in Tshwane, South Africa

Background

Risk factors for alcohol use originate from many interconnected factors to an interplay of social and physical environments. However, there is a scarcity of data on the contextual risk factors of alcohol use among the adolescents regarding high schools located in townships in South Africa. This study aimed to determine the risk factors for alcohol use among adolescents attending selected township high schools in Tshwane, South Africa.

Method

A validated researcher-administered questionnaire was used to collect data on the demographics, as well as current alcohol use, types, quantity, and frequency among adolescents (n = 403) in the three high schools. Data were analyzed using STATA 17.

Results

The response rate was 97%, with the mean age of 16 ± 2 years for the adolescents. Forty-eight % (48%) of the adolescents reported current alcohol use, which was associated with sex, age, number of children, school grade, repeated grade, spare time job and types, having a pocket money to school, child social grant, transport mode to school, and smoking. The odds of current alcohol use were higher for adolescents in grade 10 [AOR = 6.71; 95% CI: 3.16-14.24], grade 11 [AOR = 4.45; 95% CI: 2.21], grade 12 [AOR = 3.05; 95% CI: 1.47-6.31], repeating a grade [AOR =2 .20; 95% CI: 1.32-3.67), and working during a spare time [AOR = 2.91; 95% CI: 1.33-6.37]. Both sexes had higher odds of alcohol use in the ages of 15-17 and 18-21 years, than adolescents aged 13-14 years.

Conclusion

Key risk factors for alcohol use among learners were sex, age, school grade, repeated grade, and working during a spare time. More evidence-based interventions that would have a greater impact in addressing alcohol use among adolescents, such as focusing on availability, marketing, and taxation of alcoholic beverages, are necessary.

Prevalence, associated factors and level of dependence of substance use among urban secondary school students, Benin

The use of psychoactive substances is constantly increasing, particularly among young people. This study aimed to estimate the prevalence, associated factors and the level of dependence of those substances among secondary school students in Benin. This cross-sectional study included 627 students in grades 8-12, selected using a multi-stage sampling technique. Data were collected using the ASSIST questionnaire, followed by urine screening. Logistic regression analysis was performed to estimate factors associated with substance use. Overall, the lifetime prevalence of psychoactive substance use was 95.4% (95% CI = 93.4-96.9), while the current use was 78.8% (95% CI = 75.3-81.9). The most commonly used substances in the past 3 months were alcohol, followed by stimulants and tobacco; 221 samples were analysed. Twenty-two (9.95%) were positive by urine screening. Substances detected were tramadol, fentanyl, THC, K2, BZDs, alcohol, methamphetamine and cotinine. Of the current users, 2.27% (n = 11) were at high risk of dependency. An association was found between substance use and age (p = 0.02). In conclusion, this study came up with a high prevalence of substance use among students. There is a need to develop and implement a health education programme in secondary schools to raise awareness of the potential risks.

Profiles of substance use related protective and risk factors and their associations with alcohol and tobacco use initiation among black adolescents

Insufficient attention to protective and risk factors of particular salience for Black youth (e.g., racial identity and racial discrimination) in population-based substance use studies has left gaps in our understanding of alcohol and tobacco use development in Black adolescents. The current study aimed to capture the clustering of such understudied factors and their collective influence on alcohol and tobacco use initiation among Black adolescents. Data were drawn from The National Survey of American Life (n = 1,170; age range = 13-17; 6.9% Afro Caribbean, 93.1% African American; 50.0% female). Latent profile analysis applied to 11 indicators representing family, community, and individual level protective and risk factors revealed (1) High Vulnerability (high risk, low protective factors; 17.5%), (2) Moderate Vulnerability (moderate on both; 63.2%), and (3) Low Vulnerability (high protective, low risk factors; 19.3%) classes. Classes differed significantly by religious community support, school bonding, quality of relationship with mother, religious involvement, and interpersonal trauma. Relative to Class 2, Class 1 had higher odds of alcohol (OR = 1.518, CI:1.092-2.109) and tobacco use (OR = 1.998, CI:1.401-2.848); Class 3 had lower odds of alcohol (OR = 0.659, CI:0.449-0.968) but not tobacco use (OR = 0.965, CI:0.611-1.523). Findings suggest that alcohol and tobacco use initiation among Black adolescents is shaped by the collective influence of community and family level support, with commonly experienced risk factors such as non-interpersonal trauma distinguishing liability to a lesser degree. The equally modest prevalence of tobacco use among low and moderate vulnerability classes further indicates that fostering these connections may be especially effective in reducing tobacco use risk.

Illicit drug use and exposure in disadvantaged neighborhoods in Czechia: policy representations and evidence

This study examines the lifetime prevalence of illicit drug use and illicit drug exposure in disadvantaged ("Roma") and more affluent neighborhoods in Czechia. The results of a survey among populations of both types of neighborhoods suggest no statistically significant difference between the two in terms of the overall lifetime prevalence of illicit drug use; however, lifetime prevalence of methamphetamine use proved higher in disadvantaged neighborhoods. The population of disadvantaged neighborhoods has also lower chances to use LSD during their lifetime. Further differences were identified in drug exposure, with the population of more affluent neighborhoods being more frequently exposed to illicit drugs than the population of disadvantaged neighborhoods. The predictors of drug use and drug exposure were partially different for both populations. In the disadvantaged population, drug use was revealed, among other predictors, to be associated with housing conditions.

Alcohol use among adolescents in India: a systematic review

BACKGROUND

Alcohol use is typically established during adolescence and initiation of use at a young age poses risks for short- and long-term health and social outcomes. However, there is limited understanding of the onset, progression and impact of alcohol use among adolescents in India. The aim of this review is to synthesise the evidence about prevalence, patterns and correlates of alcohol use and alcohol use disorders in adolescents from India.

METHODS

Systematic review was conducted using relevant online databases, grey literature and unpublished data/outcomes from subject experts. Inclusion and exclusion criteria were developed and applied to screening rounds. Titles and abstracts were screened by two independent reviewers for eligibility, and then full texts were assessed for inclusion. Narrative synthesis of the eligible studies was conducted.

RESULTS

Fifty-five peer-reviewed papers and one report were eligible for inclusion in this review. Prevalence of ever or lifetime alcohol consumption ranged from 3.9% to 69.8%; and prevalence of alcohol consumption at least once in the past year ranged from 10.6% to 32.9%. The mean age for initiation of drinking ranged from 14.4 to 18.3 years. Some correlates associated with alcohol consumption included being male, older age, academic difficulties, parental use of alcohol or tobacco, non-contact sexual abuse and perpetuation of violence.

CONCLUSION

The evidence base for alcohol use among adolescents in India needs a deeper exploration. Despite gaps in the evidence base, this synthesis provides a reasonable understanding of alcohol use among adolescents in India and can provide direction to policymakers.

Economic costs of cigarette smoking among adolescents in Nigeria

Background

Cigarette smoking is an established cause of preventable death and often initiated during adolescence. We estimated the short- and long-term costs of cigarette smoking among currently smoking adolescents in Nigeria.

Methods

A cross-sectional survey among adolescents in Oyo state, Nigeria and a review of mortality records of patients managed for lung cancer in a tertiary facility in Ibadan, Nigeria were conducted. Short-term costs estimated were: (a) average weekly costs of purchasing cigarettes by currently smoking adolescents, and (b) costs of managing at least an episode of chronic cough occurring within 12 months of the survey. Long-term costs were limited to: (a) life-time expenditure on purchasing cigarettes, and (b) direct medical and non-medical (transportation) costs of managing lung cancer. Long-term costs were first projected to the approximate year when the adolescents (mean age:16.0 ± 1.8 years) might be diagnosed with lung cancer based on the average age at presentation with symptoms of lung cancer obtained from the records (59.8 years), and then discounted to 2020 prices. This was estimated as 44 years from the base year (2020). Costs were reported in 2020 prices in Nigerian Naira (NGN) and US dollar (USD) equivalent using the Central Bank of Nigeria, June 2020 exchange rate of USD 1: NGN 360.50.

Results

Approximately 3.8% of the adolescents were current cigarette smokers. Average weekly expenditure on cigarettes was NGN 306.82 ± 5.74 (USD 0.85 ± 0.02). About 26% had experienced at least an episode of chronic cough which cost them an average of NGN 1226.81 ± 6.18 (USD 3.40 ± 0.02) to manage. Total future costs of cigarette smoking in 2020 prices for the 43 adolescents who were current smokers in the event that they develop lung cancer were approximately NGN 175.7 million (USD 487.3 thousand), NGN 871.8 million (USD 2.4 million) and NGN 4.6 trillion (USD 12.7 million) at assumed annual inflation rates of 10%, 15%, and 20% respectively and discount rate of 4.25%.

Conclusion

The estimated economic costs of smoking were very high. Efforts to prevent smoking initiation among adolescents in our study area should be intensified. Interventions to subsidize the medical cost of health-related consequences of cigarette smoking are also required, especially as treatment costs are currently largely borne out-of-pocket.

Correlates of alcohol experimentation and drunkenness episodes among secondary-school students in Nigeria

Background: Alcohol is the most used substance among adolescents in Nigeria. While risk factors for alcohol use among adolescents are well documented in Europe and the US, they have received less attention in the literature on African countries. This study aimed to investigate the factors associated with alcohol experimentation and drunkenness episodes in a national sample of Nigerian adolescents. Methods: A total sample of 4,078 secondary-school students participated in the survey during the school year 2015-2016. The survey involved 32 secondary schools of six geopolitical zones (South-South, South-West, South-East, North-Center, North-West, and North-East) and two metropolitan cities (Abuja and Lagos) of Nigeria. Sociodemographic characteristics, parental alcohol use and permissiveness, friends' alcohol use, risk perceptions and beliefs were investigated as correlates of alcohol experimentation and drunkenness episodes through multilevel, mixed-effect logistic regression models. Results: The prevalence of alcohol experimentation was 34.0%, while the prevalence of drunkenness episodes was 13.4%. Results showed that male gender, family structure different from both parents' families, parental and friends' alcohol use, parental permissiveness to drink, low risk perceptions on drinking alcohol, and positive beliefs on consequences of alcohol use were associated with an increased probability of alcohol experimentation and drunkenness episodes. Family affluence and one-parent family structure were related to an increased probability of alcohol experimentation but not of drunkenness episodes. Conclusions: The majority of risk factors analyzed in this study generalize across drinking-behavior outcomes. Since the young population is dominant in Nigeria, alcohol use could become a big public health problem in the near future. High investment in adolescents' well-being by addressing the factors that contribute to drinking behavior might help to reduce the burden of the problem. Evidence-based prevention curriculum addressing knowledge, risk perceptions, beliefs on consequences of alcohol use, and parental behaviors should be implemented as widely and early as possible.

Evaluation of Internet Gaming Disorder, Social Media Addiction, and Levels of Loneliness in Adolescents and Youth with Substance Use

Substance use and addictive disorders are among the most significant public health concerns, particularly during adolescence. The current study aims to investigate internet gaming disorder, social media addiction, and loneliness levels in adolescents and youths with substance use. Methods: The study group consisted of 93 adolescents and youths aged 15-24 who presented to the Alcohol and Substance Addiction Research and Application Center or the Child and Adolescent Mental Health and Diseases outpatient clinic for substance use. Ninety-one healthy volunteers who did not use substances during any period of their lives participated as a control group. The participants fulfilled the Social Media Addiction Scale (SMAS), Internet Gaming Disorder Scale - Short-Form (IGDS9-SF), UCLA Loneliness Scale (UCLA-LS), and Drug Use Disorders Identification Test - Extended (DUDIT-E). Results: The symptoms of internet gaming disorder were significantly lower in the patient group compared with the control group. Although it was not significant, social media addiction was higher in the patient group than in the control group. The experience of loneliness was significantly higher in the patient group than in the control group. A significant negative correlation was found between treatment motivation and loneliness. Conclusions: School guidance teachers should monitor children who do not have friends or are lonely and be aware of the potential for substance use because it can emerge as a method of coping with the feeling of loneliness among adolescents. In future studies, investigating comprehensive factors contributing to different addictive behaviors may help to clarify the co-occurrence.

Substance use amongst high school learners in the south of Johannesburg: Is this the new norm?

Background

Substance use amongst high school learners is common in South Africa, with related risky behaviours and outcomes. Because of the social and geographical trends, studies in various parts of the country are essential to contribute to the understanding of the overall picture. The purpose of this study was to determine the prevalence of substance use, as well as the factors associated with substance use in a sample of high school learners in a suburb south of Johannesburg.

Methods

A quantitative cross-sectional survey, by using a self-administered questionnaire, was conducted amongst 308 learners in four high schools. The parents of all the learners provided consent for their children to participate in the study.

Results

The sample consisted of 308 learners who were in grades 8–12, with a mean age of 16.3. The majority (57%, n = 177) were females and 43% (n = 131) were males. The prevalence of substance use was 31% (n = 94), with 52% (n = 49) of those who use substances being male, compared with 48% (n = 45) females. Of those who used substances, 69% (n = 65) used alcohol, 10% (n = 9) smoked dagga, 5% (n = 5) smoked cigarettes, 7% (n = 7) used other substances and 46% (n = 43) were polyusers. Age, missing school because of illness, use of leisure time and friends using substances were significantly associated with the use of substances (p < 0.05).

Conclusion

The prevalence of substance use was high at 31%, which is of concern because the use of legal psychoactive substances remains illegal for minors. The risky factors associated with the use of substances highlight the threat that this behaviour has on the social well-being and educational outcomes of the learners.

Is vulnerability associated with substance use? A study among youth in Switzerland

Adolescence is a period of exploration and experimentation that includes risk behaviors such as substance use. Adolescents living in a situation of vulnerability could be more prone to using substances. In this cross-sectional study, we aimed to evaluate the association between the level of vulnerability and substance use considering explanatory factors. Data were obtained from the first wave of the GenerationFRee project (http://www.generationfree.ch), a longitudinal study based on data collected yearly between 2014 and 2019 on youth aged 15-24 years in high schools and professional schools. The sample included 5179 participants. We designated four risk behaviors: current tobacco smoking, alcohol misuse, cannabis use, and other illegal drug use. We defined vulnerability based on three criteria: the relationship with parents, school performance, and the family socioeconomic status (SES). According to this definition, participants were divided into three groups: no vulnerability, moderate vulnerability, and high vulnerability. Each substance was compared by vulnerability level and controlled with explanatory factors such as age, gender, perceived health, emotional well-being, academic track, nationality, living with parents, residence, family structure, money earned, and perceived personal financial situation. The results show that all substances except alcohol misuse are associated with vulnerability at the bivariate level. All the explanatory factors were also significant with the exception of academic track and amount of money earned per month. In the multinomial regression, for the moderate- and high-vulnerability groups, cannabis use was the only behavior that remained significant. In conclusion, this study shows the association between level of vulnerability and substance use, especially cannabis use. The results also demonstrate the complexity around vulnerability and how the interaction with social aspects influences vulnerability. Youths presenting familial, educational, or financial problems need to be especially screened for substance use by healthcare providers.

Assessment of Exposure to Sexually Explicit Materials and Substance Abuse among High-School Adolescents in North Shewa Zone: Application of Logistic Regression Analysis

Background

The use of substances such as cigarettes, khat, alcohol, and other illicit drugs like hashish, heroine, cannabis, and cocaine is a global major public threat, which affects young adult people particularly in developing countries. This study aims to assess the risk factors associated with substance use and exposure to sexually explicit materials among high-school adolescents in north Shewa zone, Oromia region.

Method

A cross-sectional study was conducted to assess substance use and exposure to sexually explicit materials among high-school adolescents in North Shewa zone, Oromiya, Ethiopia, using a structured self-administered questionnaire adapted from the 2008 “Community That Care Youth Survey” for adolescent substance use and problem behaviors. The study used descriptive statistics and logistic regression analysis to identify the significant factors associated with substance use and exposure to sexually explicit materials among high school adolescents in the study area.

Result

The prevalence of lifetime and current substance use was 47.7% (95% CI: 0.427, 0.527) and 30.4% (95% CI: 0.258, 0.350), respectively. 17.8% use khat in their life and 16.6% used khat in the past 30 days; 42.2% ever used alcohol and 26.1% currently uses alcohol; 4.8% and 4.5% used cigarette in lifetime and in the past 30 days, while 16.4% use other illicit drugs in lifetime and 8.4% use illicit drugs in the past 30 days, respectively. Distributions of substance use by sex indicate that male adolescents are more like likely 61.1% use substances than females. While, the prevalence of exposure to sexually explicit materials among high school adolescents was 35.8% (95% CI: 0.310, 0.406). Factors positively associated with increased substance use were being male (OR = 2.334, 95% CI: 1.549, 9.926), living through high level of family conflict (OR = 6.25, 95% CI: 1.745, 10.00), poor family management OR = 27.084, 95% CI: 1.624, 45.56), peer pressure (OR = 12.882, 95% CI: 1.882, 88.153), poor academic performance (OR = 14.48, 95% CI: 1.290, 162.58), and low school commitment (OR = 11.951, 95% CI: 1.418, 100.73). While, being male (OR = 7.52, 95% CI: 2.611, 21.739), age 14–16 (OR = 0.201, 95% CI: 0.071, 0.565), friends watch/read sexually explicit materials (OR = 5.376, 95% CI: 1.010, 28.571), and khat chewing (OR = 12.5, 95% CI: 2.924, 25.632) were factors significantly associated with high-school adolescents exposure to sexually explicit materials.

Conclusion

The magnitude of prevalence for substance uses and exposure to sexually explicit materials in the study area was still higher. Therefore, interventions that focus on family management, peer pressure, and school commitment are required to decrease the prevalence of substance uses and exposure to sexually explicit materials among high-school adolescents.

Alcohol Consumption, Risky Sexual Behaviors, and HIV in Nigeria: A Meta-Analytic Review

BACKGROUND

Alcohol consumption is associated with risky sex, which increases the risk of acquiring and transmitting HIV.

OBJECTIVE

To examine the prevalence of, and associations among alcohol, risky sex, and HIV, in Nigeria.

METHODS

We searched electronic databases and reviewed reference sections of relevant papers to locate studies that sampled people living in Nigeria and assessed both alcohol and sexual risk behavior. We calculated effect sizes to determine (a) prevalence of alcohol and sex behaviors and (b) associations between alcohol consumption and risky sex, and examined moderators to determine if sample characteristics predicted behavioral or biological outcomes.

RESULTS

Of the 696 unique records identified, 35 manuscripts reporting on 42 separate studies met the inclusion criteria. Participants in these studies (N = 83,350; M age = 26 years; 48% women; 10% HIV-infected) reported high rates of heavy drinking (63%) and low rates of consistent condom use (24%). One-third of participants (30%) also reported using alcohol before sexual activity. Participants who consumed alcohol were more likely to report sexual activity (OR = 3.66, 95% CI = 3.09, 4.33), multiple partners (OR = 3.22, 95% CI = 2.38, 4.36), and condomless sex or inconsistent use of condoms (OR = 2.30, 95% CI = 1.54, 3.43).

CONCLUSION

High rates of heavy drinking and low rates of condom use have been well-documented in Nigeria. Results from this meta-analysis can be used to inform critically needed alcohol-related HIV interventions.

Telephone counseling for young Brazilian cocaine and/or crack users. Who are these users?

OBJECTIVE

To describe the users' drug abuse characteristics, problematic behaviors associated with addiction, the motivation of teenagers and young adults to quit cocaine and/or crack abuse, and then compare these characteristics.

METHODS

A cross-section study was conducted with 2390 cocaine/crack users (teenagers from 14 to 19 years of age, and young adults from 20 to 24 years of age); 1471 were young adults and 919 were teenagers who had called a phone counseling service between January 2006 and December 2013. Semi-structured interviews were performed via phone calls. The questionnaires included sociodemographic information; assessment of the characteristics of cocaine/crack abuse; assessment of the problematic behaviors; also, the Contemplation Ladder was used to evaluate the stages of readiness to cease substance abuse.

RESULTS

Participants reported using cocaine (48.2%), crack and other smoking forms (36.7%) and combined consumption of both drugs (15%). Young adults were more prone to using crack or crack associated with cocaine (OR=1.9; CI 95%=1.05-1.57) and they were exposed to substance abuse for longer than two years (OR=3.45; CI 95%=2.84-4.18), when compared to teenagers. On the other hand, they showed higher readiness to quit.

CONCLUSION

Data shows important differences in drug abuse characteristics, problematic behaviors and motivation to cease substance abuse between teenager and young adult cocaine and/or crack users. Behaviors displayed by young adults involve greater physical, mental and social health damages. These findings reinforce the importance of public policy to act on prevention and promoting health, to increase protection factors among teenagers and lower risks and losses during adult life.

Substance use and Psychosocial Functioning of Adolescents in Benue State, Nigeria: Assessing the role of age

AIM

To assess whether Substance Use (SU) is associated with Psychosocial Function (PF) among adolescent.

METHODS

Using a self-administered validated instrument, we obtained information on demographic, SU (defined as self-reported affirmative use of one or more of any form of alcoholic drinks, cigarettes, hemps etc) and PF [using the adolescent psychosocial functioning inventory comprising of three subscales; optimism and coping strategies (OCS), behaviour and relationship problems (BRP) and general psychosocial dysfunction designed (GPD)] among 2272 apparently healthy adolescents. PF was categorized as 'elevated' if the psychosocial functioning index (PFI) score were >75th percentile, otherwise, 'not elevated' and multivariable-adjusted logistic regression was used to compute odds ratio (OR) and 95% confidence interval (CI) of SU for elevated PF risk. In addition, we applied Johnson Neyman (JN) technique to identifying the JN significance regions at which age moderated the SU-PF relationship at a statistical significance of two-sided P<0.05.

RESULTS

Prevalence of SU and elevated PF was 50.7% and 79.8% respectively. Prevalence of elevated PF differed insignificantly by sex, but the proportion of adolescent with elevated PFI on SU (82.6%) was significantly higher (P<0.001) compared to those with elevated PFI but not on SU (76.9%). Multivariable-adjusted odds of decreased OCS risk given SU exposure was; OR (95%CI): 1.3791 (1.1458-1.6698), P=0.0007. Similarly, multivariable-adjusted odds of elevated PF risk in the light of SU exposure was; OR (95%CI): 1.4286 (1.1617-1.7567), P=0.0007. Furthermore, the JN significance regions for moderated regression analyses of odds of decreased OCS risk was between 10.4years [OR (95%CI): 0.5820 (0.1411-1.0228), P=0.0097] and 16.7years [OR (95%CI): 0.3025 (0.0001-0.6050), P=0.0500].

CONCLUSION

Adolescents on SU are about one and half times at risk of psychosocial dysfunction and age significantly attenuated the SU-decreased OCS risk link particularly in early adolescence.

Behavioural health risks during early adolescence among perinatally HIV-infected South African adolescents and same-age, HIV-uninfected peers

Behavioural health risks, including substance use, early sexual debut, bullying and suicidality, are common during adolescence, but may be complicated among perinatally HIV-infected adolescents. However, there are few data exploring these behaviours in sub-Saharan Africa. We compared behavioural health risks (any self-report of substance use, sexual activity, bullying others or suicidality, or a positive urine toxicology screen) among perinatally-infected adolescents ages 9-14 years to that of an HIV-uninfected comparator group; and explored the effect of behavioural health risks on adolescent and caregiver report of adolescent suboptimal adherence (missed antiretroviral therapy dose(s) on ≥1 day during the preceding 30 days) and elevated HIV viral load (≥50 and ≥1000 copies/mL in sensitivity analyses) in multivariable logistic regression models. Among 506 HIV-infected and 110 HIV-uninfected adolescents (median age overall: 12 years), 15% and 25% reported any behavioural health risk (p = 0.018), respectively. Tobacco and other drug use was uncommon, while alcohol use was reported by 8% of HIV-infected versus 12% of HIV-uninfected adolescents (p = 0.185). One HIV-infected (0.2%) and 3 HIV-uninfected adolescents (3%) reported any sexual activity (p = 0.019). Among HIV-infected adolescents, report of any behavioural health risk was more common among male adolescents [adjusted odds ratio (aOR): 1.78; 95% confidence interval (CI): 1.08-2.95] and was associated with adolescent report of suboptimal adherence (aOR: 1.66; 95% CI: 0.99-2.78) but not with caregiver report of suboptimal adherence or with elevated viral load. In this group of perinatally-infected youth entering early adolescence, the prevalence of behavioural health risks was lower than that among same-age, HIV-uninfected peers. Longitudinal data are needed to explore the reasons underlying these differences, for example the possibility of more protective caregiving and supportive family environments, or of emotional and physical immaturity, as well as the emergence of risk behaviours over time in this population.

Understanding Educational and Psychosocial Factors Associated with Alcohol Use among Adolescents in Denmark; Implications for Health Literacy Interventions

Background. Alcohol misuse is a global public health priority, with a variation in prevalence and impact between countries. Alcohol misuse in adolescence is associated with adverse psychological, social and physical health. Adolescents in Denmark have higher alcohol consumption and problematic alcohol use than adolescents in other European countries. Associations between social determinants of health (SDH), psycho-social factors and alcohol consumption are complex and influenced by national context and cultures. This study explored these associations in Danish adolescents. Method. The European School Survey Project on Alcohol and Other Drugs (ESPAD) survey collects data on alcohol and substance use among 15⁻16-year-old European students. Data contributed by Danish students to the 2011 survey were analyzed. The outcomes of interest were alcohol consumption (any, intoxication and problematic). Health literacy was not directly measured, so self-described educational performance and knowledge about alcohol were used as proxies for health literacy. Exploratory factors thus included socio-demographic, health literacy-related (knowledge about alcohol, educational performance) and psycho-social factors, as well as expectancies of the effect of alcohol (both positive and negative) and self-reported health. Univariate and multivariate logistic regression analyses were undertaken. Results. Of the 2768 adolescents who participated in the survey, 2026 (80%) consumed alcohol during the last 30 days, 978 (38%) were intoxicated at least once during the last 30 days, and 1050 (41%) experienced at least one problem because of alcohol use during the last 12 months. Multivariable analysis showed that the factors associated with higher alcohol intake were gender, poor relationships with parents, expectancies of the impact of alcohol (both positive and negative), and the influence of peers and their alcohol use. Higher school performance was related to lower alcohol consumption. Low socio-demographic status was not associated with higher alcohol consumption. Conclusions. This study confirmed the high levels of alcohol intake, intoxication, and problem drinking amongst the Danish students in the survey and the complexity of the socio-demographic, psychosocial, health literacy-related, and environmental factors associated with alcohol behaviours. Approaches to addressing the issue of alcohol use in Danish adolescents will need to be multi-factorial, including supporting students to develop alcohol-related health literacy skills to enable them to make informed choices.

Problem Drinking, Alcohol-Related Violence, and Homelessness among Youth Living in the Slums of Kampala, Uganda

This paper examines problem drinking, alcohol-related violence, and homelessness among youth living in the slums of Kampala—an understudied population at high-risk for both alcohol use and violence. This study is based on a cross-sectional survey conducted in 2014 with youth living in the slums and streets of Kampala, Uganda (n = 1134), who were attending Uganda Youth Development Link drop-in centers. The analyses for this paper were restricted to youth who reported current alcohol consumption (n = 346). Problem drinking patterns were assessed among youth involved in alcohol-related violence. Mediation analyses were conducted to examine the impact of homelessness on alcohol-related violence through different measures of problem drinking. Nearly 46% of youth who consumed alcohol were involved in alcohol-related violence. Problem drinkers were more likely to report getting in an accident (χ² = 6.8, df = 1, p = 0.009), having serious problems with parents (χ² = 21.1, df = 1, p < 0.0001) and friends (χ² = 18.2, df = 1, p < 0.0001), being a victim of robbery (χ² = 8.8, df = 1, p = 0.003), and going to a hospital (χ² = 15.6, df = 1, p < 0.0001). For the mediation analyses, statistically significant models were observed for frequent drinking, heavy drinking, and drunkenness. Interventions should focus on delaying and reducing alcohol use in this high-risk population.

Intersections between polyvictimisation and mental health among adolescents in five urban disadvantaged settings: the role of gender

BACKGROUND

Polyvictimisation (PV) - exposure to violence across multiple contexts - causes considerable morbidity and mortality among adolescents. Despite high levels of violence in urban disadvantaged settings, gender differences in associations between PV and mental health have not been well established.

METHODS

We analysed data from a survey with 2393 adolescents aged 15-19 years, recruited using respondent-driven sampling from urban disadvantaged settings in Baltimore (USA), Delhi (India), Ibadan (Nigeria), Johannesburg (South Africa) and Shanghai (China). PV was defined as exposure to two or more types of violence in the past 12 months with family, peers, in the community, or from intimate partners and non-partner sexual violence. Weighted logistic regression models are presented by gender to evaluate whether PV is associated with posttraumatic stress, depression, suicidal thoughts and perceived health status.

RESULTS

PV was extremely common overall, but ranged widely, from 74.5% of boys and 82.0% of girls in Johannesburg, to 25.8 and 23.9% respectively in Shanghai. Community violence was the predominant violence type, affecting 72.8-93.7% across the sites. More than half of girls (53.7%) and 45.9% of boys had at least one adverse mental health outcome. Compared to those that did not report violence, boys exposed to PV had 11.4 higher odds of having a negative perception of health (95%CI adjusted OR = 2.45-53.2), whilst this figure was 2.58 times in girls (95%CI = 1.62-4.12). Among girls, PV was associated with suicidal thoughts (adjusted OR = 4.68; 95%CI = 2.29-9.54), posttraumatic stress (aOR = 4.53; 95%CI = 2.44-8.41) and depression (aOR = 2.65; 95%CI = 1.25-5.63). Among boys, an association was only detected between PV and depression (aOR = 1.82; 95%CI = 1.00-3.33).

CONCLUSION

The findings demonstrate that PV is common among both sexes in urban disadvantaged settings across the world, and that it is associated with poor mental health outcomes in girls, and with poor health status in both girls and boys. Clearly, prevention interventions are failing to address violence exposure across multiple contexts, but especially within community settings and in Johannesburg. Interventions are needed to identify adolescents exposed to PV and link them to care, with services targeting a range of mental health conditions among girls and perhaps focusing on depression among boys.

Social causation and neighborhood selection underlie associations of neighborhood factors with illicit drug-using social networks and illicit drug use among adults relocated from public housing

Theories of social causation and social influence, which posit that neighborhood and social network characteristics are distal causes of substance use, are frequently used to interpret associations among neighborhood characteristics, social network characteristics and substance use. These associations are also hypothesized to result from selection processes, in which substance use determines where people live and who they interact with. The potential for these competing selection mechanisms to co-occur has been underexplored among adults. This study utilizes path analysis to determine the paths that relate census tract characteristics (e.g., economic deprivation), social network characteristics (i.e., having ≥ 1 illicit drug-using network member) and illicit drug use, among 172 African American adults relocated from public housing in Atlanta, Georgia and followed from 2009 to 2014 (7 waves). Individual and network-level characteristics were captured using surveys. Census tract characteristics were created using administrative data. Waves 1 (pre-relocation), 2 (1st wave post-relocation), and 7 were analyzed. When controlling for individual-level sociodemographic factors, residing in census tracts with prior economic disadvantage was significantly associated with illicit drug use at wave 1; illicit drug use at wave 1 was significantly associated with living in economically-disadvantaged census tracts at wave 2; and violent crime at wave 2 was associated with illicit drug-using social network members at wave 7. Findings from this study support theories that describe social causation and neighborhood selection processes as explaining relationships of neighborhood characteristics with illicit drug use and illicit drug-using social networks. Policies that improve local economic and social conditions of neighborhoods may discourage substance use. Future studies should further identify the barriers that prevent substance users from obtaining housing in less disadvantaged neighborhoods.

Using photovoice in adolescent health research: a case-study of the Well-being of Adolescents in Vulnerable Environments (WAVE) Study in Ibadan, Nigeria

Photovoice is a participatory action research method in which people are given cameras and asked to take pictures of specific issues within their community. It is often used among marginalised populations. This method helps people capture specific issues within their community using photographs, critically discuss these issues within a group and present their findings to inform policies within their community. Photovoice has been used in developed countries and among adult participants; however, the extent to which it has been used in developing countries and among adolescent participants is yet to be extensively reported. In this paper, we describe the use of photovoice among male and female adolescents aged 15-19 years who participated in the qualitative phase (phase I) of the Well-being of Adolescents in Vulnerable Environments (WAVE) study in Ibadan, Nigeria. The main study was conducted among adolescents residing in disadvantaged communities within five global cities (Baltimore, USA; Ibadan, Nigeria; Johannesburg, South Africa; New Delhi, India and Shanghai, China). Our findings revealed that adolescents in Ibadan were very eager to participate, remained fully engaged throughout the process and the data obtained were rich and detailed. Some challenges encountered with using this method were that younger adolescents had a tendency to attain saturation when taking pictures much earlier than older adolescents; however, they equally discussed the pictures taken enthusiastically. Overall, our findings affirm that photovoice as a data collection method can be successfully used in research among adolescents in developing countries like Nigeria.

Risk perception and correlates of alcohol use among out-of-school youth in motor parks in Lagos State, Nigeria

BACKGROUND AND AIM

The prevalence of alcohol use has increased globally. Out-of-school youth are a vulnerable group who might have missed opportunities for learning healthy behaviours in a formal school environment. The purpose of this study was to determine the risk perception, pattern of use, and correlates of alcohol use among out-of-school youth in Lagos, Nigeria.

METHODS

A cross-sectional study was conducted among 380 out-of-school youth in motor parks in Lagos State, Nigeria, using interviewer administered questionnaires.

RESULTS

The lifetime prevalence of alcohol use was 61.1%, while 55.5% were current drinkers. Beer (57.3%) was the most consumed type of alcohol, followed by distilled spirits (29.8%). Using the CAGE scoring system, more than half (57.8%) of the current drinkers had a drinking problem. Almost three quarters (70.1%) had experienced at least one episode of alcohol intoxication within the past month. A considerable number of current drinkers (63.5%) desired to reduce their alcohol intake or stop drinking, while 45.5% had made unsuccessful attempts to do so within the past year. Only 28.9% had received assistance to quit or reduce their drinking and of these less than half (39.3%) received assistance from a professional or healthcare worker. Males were more likely to be current drinkers and to have experienced episodes of alcohol intoxication. Parental and peer drinking were associated with alcohol use but not with intoxication.

CONCLUSIONS

It is important to design specific programmes to reduce alcohol use among out-of-school youth in these settings.

People and places: Relocating to neighborhoods with better economic and social conditions is associated with less risky drug/alcohol network characteristics among African American adults in Atlanta, GA

BACKGROUND

Few studies assess whether place characteristics are associated with social network characteristics that create vulnerability to substance use.

METHODS

This longitudinal study analyzed 7 waves of data (2009-2014) from a predominantly substance-using cohort of 172 African American adults relocated from public housing complexes in Atlanta, GA, to determine whether post-relocation changes in exposure to neighborhood conditions were associated with four network characteristics related to substance use: number of social network members who used illicit drugs or alcohol in excess in the past six months ("drug/alcohol network"), drug/alcohol network stability, and turnover into and out of drug/alcohol networks. Individual- and network-level characteristics were captured via survey and administrative data were used to describe census tracts where participants lived. Multilevel models were used to assess relationships of census tract-level characteristics to network outcomes over time.

RESULTS

On average, participants relocated to census tracts that had less economic disadvantage, social disorder, and renter-occupied housing. Post-relocation reductions in exposure to economic disadvantage were associated with fewer drug/alcohol network members and less turnover into drug/alcohol networks. Post-relocation improvements in exposure to multiple census tract-level social conditions and reductions in perceived community violence were associated with fewer drug/alcohol network members, less turnover into drug/alcohol networks, less drug/alcohol network stability, and more turnover out of drug/alcohol networks.

CONCLUSION

Relocating to neighborhoods with less economic disadvantage and better social conditions may weaken relationships with substance-using individuals.

Distressed communities as a breeding ground for noncommunicable conditions

Recent research has driven home the close relationship between place and health. Geography is often a greater driver of adolescent morbidity and mortality than behavior. To elucidate these relationships, the Well-Being of Adolescents in Vulnerable Environments study has collected and analyzed data on the health and well-being of adolescents' lowest income communities of five cities: Baltimore, United States; Ibadan, Nigeria; Johannesburg, South Africa; New Delhi, India; and Shanghai, China.
