Individual and contextual factors associated with tobacco,alcohol, and cannabis use among Chilean adolescents: A multilevel study

We studied the association between individual and contextual variables and the use of tobacco, alcohol, or cannabis in the last 30 days preceding the study, considering the hierarchical nature of students nested in schools. We used the 7th Chilean National School Survey of Substance Use (2007) covering 45,273 students (aged 12–21 years old) along with information from 1465 schools provided by the Chilean Ministry of Education. Multilevel univariable and multivariable logistic regression models were performed. We found a significant intra-class correlation within schools for all substances in the study. Common (e.g., availability of pocket money, more time spent with friends, poor parental monitoring, poor school bonding, bullying others, and lower risk perception of substance use) and unique predictors (e.g., school achievement on national tests) were identified. These findings may help in planning and conducting preventive interventions to reduce substance use.     

Family and peer influences on tobacco use among adolescents with psychiatric disorders

The purpose of this study was to examine family and peer influences on smoking behaviors among 239 (191 smokers; 48 nonsmokers) psychiatrically hospitalized adolescents. Participants were queried using scales to measure parental supervision and monitoring, parenting style, adolescent-parent communication, family conflict and relations with parents, and the importance placed on life goals. The results of this study are consistent with previous findings from general population studies. Psychiatrically hospitalized adolescents' smoking status were also correlated with their siblings', peers', and girlfriends'/boyfriends' smoking status. In addition, we found that parental monitoring, closeness to parents, and ambitious life goals were protective factors against smoking. As a result, peer and family influences strongly impact the initiation and maintenance of adolescent smoking and should be considered when designing smoking cessation interventions for adolescents with psychiatric disorders.     

Psychiatric functioning and substance use: factors associated with HIV risk among incarcerated adolescents

This study examined several types of psychiatric functioning (neuropsychiatric, emotional, and cognitive functioning) and substance use in relation to HIV risk behavior among 894 incarcerated girls and boys. Youth remanded to juvenile correctional facilities in a southern US state completed a structured interview regarding abuse history, emotional and behavioral difficulties, and demographics. Adolescents who experienced sullen affect were significantly more likely to engage in behaviors that put them at risk for HIV infection. Moreover, higher levels of alcohol use predicted HIV risk behavior. HIV prevention efforts need to address emotional distress as well as substance use among delinquent adolescents to reduce HIV risk behavior. Implications for treatment and future research are discussed.     

Psychosocial factors associated with help-seeking behavior among depressive adolescents

A group of 3,287 French school pupils between the age of 12 to 20 years, of whom 14.4% had sought consultation for depression, were investigated in order to analyse the factors related to the type of medical help obtained. Multivariate analyses showed that severe emotional distress alone did not explain the help-seeking behavior. Thus, among those adolescents with the same anxio-depressive level, girls, older adolescents, adolescents with parents living apart, with health worries, and adolescents often absent from school more often sought help for depression. Socioeconomic status, however, did not correlate with a higher level of consultation for depression. Adolescents attending medical services for depression had a higher consultation rate, for any reason, with general practitioners and with school nurses, in whom they confided more often than their counterparts. Nonmedical professionals also seemed to contribute to accessing to medical help for depression. Overall, those who consulted for depression, in very limited numbers turned to mental health services (8.4%).     

Family, peer and individual factors related to methylenedioxymethamphetamine use in Taiwanese adolescents

Examination of the correlates of methylenedioxymethamphetamine (MDMA) use is crucial for the development and implementation of effective prevention programs for adolescents. The aim of the present study was therefore to identify the family, peer and individual factors that were related to MDMA use in Taiwanese adolescents. Two hundred adolescents who used MDMA and 200 who did not use MDMA were recruited into the study. The family, peer and individual factors related to MDMA use were examined using chi(2) automatic interaction detection (CHAID) analysis. The results indicated that the adolescents who had more friends involved with substance use, disruptive family and attitude favoring MDMA use were more likely to use MDMA. Multiple factors of family, peer and individuals were related to MDMA use among Taiwanese adolescents. This knowledge may be helpful when designing and implementing preventive intervention programs.     

Poor sleep quality is associated with discordant peer relationships among adolescents with Autism Spectrum Disorder

BackgroundIndividuals with Autism Spectrum Disorder (ASD) experience impairments in social communication, and these deficits often make it difficult to form and maintain friendships with peers. Poor sleep quality and daytime sleepiness are common among adolescents with ASD, and consequences of poor sleep may make social interactions difficult. Connections between sleep quality and social relationships in ASD samples have been understudied; the current study addresses this gap.MethodParticipants were community samples of 19 adolescents with ASD and 10 neurotypical (NT) adolescents. Adolescents completed questionnaires about closeness and discord in relationships with a same-gender peer, and they reported on sleep-wake problems, daytime sleepiness, and internalizing problems. Adolescents also wore an actigraph for 7-nights.ResultsPearson correlations revealed significant associations between adolescents’ reports of sleep problems and discordant peer relationships; more sleep-wake problems and more daytime sleepiness were associated with more discord with peers in the sample with ASD, but not in the NT sample. The closeness aspect of peer relationships was not significantly associated with sleep quality. Internalizing problems did not mediate between sleep quality and discordant relationships.ConclusionsAdolescents’ reports of more sleep problems and daytime sleepiness, but not actigraph indicators of sleep quality, were directly associated with discordant peer relationships. Adolescents who are already challenged in social interactions due to ASD may be especially vulnerable to intense negativity in peer relationships when they also experience poorer nighttime sleep and more daytime sleepiness. NT adolescents may be better able to regulate social interactions despite poor sleep and feeling tired.     

Suicidal ideation and associated factors among community-dwelling elders in Taiwan

The purpose of the present study was to explore the suicidal ideation of community-dwelling elderly and the factors associated with their intention to commit suicide. Using a multilevel stratified sampling strategy, 1000 elderly subjects were recruited (aged 65-74 years old) in Taiwan during the year 2001. The degree of depression and its correlates were assessed. Suicidal ideation was measured by asking respondents if they had had any suicidal thoughts in the previous week. In all, 16.7% of respondents reported suicidal ideation within the past week; its occurrence was related to sex, religious belief, employment status, marital status, average family monthly income, physical health status, depressive symptoms, and community activity participation. Further multivariate logistic regression revealed that, aside from depressive symptoms and a lower level of education, no community participation in the past 6 months was significantly associated with the appearance of suicidal ideation. The prevalence of suicidal ideation among the elderly in Taiwan is higher than in Western countries. Participation in social activities is negatively associated with elderly suicidal ideation. The dimension of social participation deserves further exploration and should be considered in community mental health promotion interventions for elderly people.     

Gender and other risk factors associated with risky behaviours among Nigerian adolescents

Risky behaviours in adolescents, apart from substance use, and their associate factors, have not been thoroughly investigated in Nigeria. Hence, there is a need to study the prevalence of risky behaviours and their relationship with gender and other potential risk factors. Data comprising socio-demographic, risky behaviours, personality traits, religious orientation and substance use were obtained from 300 randomly selected secondary school students. Two risk groups (low and high) based on the number of risky behaviours were determined. Male was a risk factor for theft (OR = 2.1; 95%CI = 1.17–3.95), bullying (OR = 2.76; 95%CI = 1.37–5.56) and fighting (OR = 2.14; 95%CI = 1.35–3.40). Fifty-two (17.3%) of the students were of high-risk behaviour group. Furthermore, private school (β = 1.05; P = 0.010), poor perceived relationship with teachers (β = 1.21; P = 0.002), polygamy (β = 1.20; P = 0.002) and lifetime cigarette use (β = 1.07; P = 0.027) were predictors of high-risk behaviour group. Substantial proportion of adolescents in Nigeria exhibit risky behaviours of which gender and other factors play a significant role.     

Estimating peer effects in sexual behavior among adolescents

In this paper we seek to empirically quantify the role of peer social networks in influencing sexual behavior among adolescents. Using data of a nationally representative sample of adolescents we utilize a multivariate structural model with school-level fixed effects to account for the problems of contextual effects, correlated effects and peer selections to purge the potential biases from the estimates of peer influence. Our peer group measures are drawn not only from the nomination of close friends, but also from classmates. Controlling for parent level characteristics, and other demographic parameters, we find that a 10% increase in the proportion of close friends who initiates sex increases the probability that an individual chooses to initiate sex by 5% and a 10% increase in number of sexual partners among close friends increases an individual's sexual partner by 5%. The influence of classmates however, diminishes in magnitude after accounting for unobserved environmental confounders.     

Depression and its association with self-esteem, family, peer and school factors in a population of 9586 adolescents in southern Taiwan

Aims:  The aim of the present study was to gain insight into the prevalence of depression and its association with self-esteem, family, peer and school factors in a large-scale representative Taiwanese adolescent population.
Methods:  A total of 12 210 adolescent students were recruited into the present study. Subjects with a score >28 on the Center for Epidemiological Studies' Depression Scale were defined as having significant depression; the Rosenberg Self-Esteem Scale, Adolescent Family and Social Life Questionnaire and Family C-APGAR Index were applied to assess subjects' self-esteem, family, peer and school factors. The association between depression and correlates were examined on t -test and χ² test. The significant factors were further included in logistic regression analysis.
Results:  Among 9586 participants (response rate: 86.3%), the prevalence of depression was 12.3%. The risk factors associated with depression in univariate analysis included female gender, older age, residency in urban areas, lower self-esteem, disruptive parental marriage, low family income, family conflict, poorer family function, less satisfaction with peer relationships, less connectedness to school, and poor academic performance. After adjusting the effects of sex, age and location, only subjects with lower self-esteem, higher family conflict, poorer family function, lower rank and decreased satisfaction in their peer group, and less connectedness to school were prone to depression on logistic regression.
Conclusion:  The prevalence of depression is high in Taiwanese adolescents, and the multiple factors of family, peer, school and individuals are associated with adolescent depression. The factors identified in the present study may be helpful when designing and implementing preventive intervention programs.     

The use of Pap smear and its influencing factors among women with disabilities in Taiwan

Cervical cancer is a prevalent cancer among Taiwanese women, and can be effectively cured if diagnosed early. Therefore, cervical cancer is worthy of preventive health screening. Due to physical and psychological barriers, patients with disability may be unable to express their physical complaints accurately, thus reducing their access to health care; some may not even receive proper preventive health care or medical treatment. This study investigates the utilization of Pap smear among women with disability in Taiwan and its influencing factors. With women aged 30 and over as the study subjects, this retrospective cohort study is conducted based on the database of the Ministry of the Interior, Taiwan, 2008, combined with information gathered between 2006 and 2008 regarding preventive health care and health insurance medical claims data from the Bureau f Health Promotion and the National Health Research Institutes, respectively. The frequency of Pap smears and the percentage differences of each variable are examined using the 2× tests to check for statistical significance. Finally, logistic regression analysis is used to examine the factors influencing the use of Pap smears. The results revealed that among disabled women aged 30 and over, the use of Pap smears was 7.71% in 2008. Disabled women with the following characteristics had lower use levels regarding Pap smears: greater age, residing in areas of higher urbanization, lower income, lower education levels, unmarried, not diagnosed with cancer, diagnosed with diabetes, and with severe disability levels. Disabled women with hearing impairments or mental retardation were possessed of the highest and lowest probabilities of using Pap smear, respectively. The recommendations of this study include: (1) provide physicians with a varying pricing scheme and incentives for Pap smear based on the type or severity of disability; (2) proactively encourage gynecologist and obstetricians to conduct regular and convenient Pap smear on disabled women; and (3) target disabled women in low usage groups, and improve their knowledge of Pap smear.     

Prevalence and associated factors of physical fighting among school-going adolescents in Namibia

Background

Interpersonal physical violence is an important global public health concern that has received limited attention in the developing world. There is in particular a paucity of data regarding physical violence and its socio-demographic correlates among in-school adolescents in Namibia.

Methods

We analysed cross-sectional data from the Namibia Global School-Based Health Survey (GSHS) conducted in 2004. We aimed to estimate the prevalence and socio-demographic correlates of physical fighting within the last 12 months. We obtained frequencies of socio-demographic attributes. We also assessed the association between self-reported history of having engaging in a physical fight and a selected list of independent variables using logistic regression analysis.

Results

Of the 6283 respondents, 50.6% (55.2% males and 46.2% females) reported having been in a physical fight in the past 12 months. Males were more likely to have been in a physical fight than females (OR = 1.71, 95% CI (1.44, 2.05)). Smoking, drinking alcohol, using drugs and bullying victimization were positively associated with fighting (OR = 1.91, 95% CI (1.49, 2.45); OR = 1.48, 95% CI (1.21, 1.81); OR = 1.55, 95% CI (1.22, 1.81); and OR = 3.12, 95% CI (2.62, 3.72), respectively). Parental supervision was negatively associated with physical fighting (OR = 0.82, 95% CI (0.69, 0.98)). Both male and female substance users (cigarette smoking, alcohol and drug use) were more likely to engage in physical fighting than non-substance users (OR = 3.53, 95% CI (2.60, 4.81) for males and OR = 11.01, 95% CI (7.25, 16.73) for females). Parental supervision was negatively associated with physical fighting (OR = 0.85, 95% CI (0.72, 0.99)).

Conclusion

Prevalence of physical fighting within the last 12 months was comparable to estimates obtained in European countries. We also found clustering of problem behaviours or experiences among adolescents who reported having engaged in physical violence in the past 12 months. There is a need to bring adolescent violent behaviour to the fore of the public health agenda in Namibia.

     

Suicidality and its relationships with individual,family, peer,and psychopathology factors among adolescents with attention-deficit/hyperactivity disorder

The aim of this study was to examine the prevalence rates of suicidal intent and its correlates among adolescents diagnosed with ADHD in Taiwan. A total of 287 adolescents aged 11–18 years and diagnosed with ADHD participated in this study. Their suicidal ideation and suicide attempts were assessed. Logistic regression analysis was used to examine the associations of suicide with individual, family, peer, ADHD, and psychopathology factors. A total of 12.2% of the participants reported suicidal ideation or a suicide attempt. A logistic regression analysis model showed that adolescents who were older, were bullying perpetrators, and reported high depression level were more likely to have suicidal intent. These three factors were also significantly correlated with suicidal ideation; however, only having high depression level was significantly correlated with suicidal attempts. The results of this study showed that a high proportion of adolescents with ADHD reported suicidal ideation or a suicide attempt. Multiple factors were significantly associated with suicidal intent among adolescents with ADHD. Clinicians, educational professionals, and parents of adolescents with ADHD should monitor the possibility of suicide in adolescents with ADHD who exhibit the correlates of suicidal intent identified in this study.     

Risk factors for substance use disorders among inpatients with major affective disorders in Taiwan Chinese

An assessment of potential risk factors for substance use disorders was performed in 49 patients with major affective disorders in a general hospital acute care unit in Taiwan. The major depression patients were noted to have a higher prevalence of substance use disorder than bipolar disorder patients (p = 0.011). Those patients with substance use disorders were noted to be significantly male-predominated (p = 0.043), to have a later onset age of affective disorder (p = 0.009), and to have more visits to the emergency room in the recent one year (p = 0.009). The sedatives-hypnotics-anxiolytics was the most frequently used forms of drug abuse. The major depression patients had a significantly higher sedative-hypnotics-anxiolytics use disorder rate than the bipolar disorder patients (p = 0.001). All patients with alcohol use disorder were noted to have other substance use disorders as well. Fifty six percent of those patients with substance use disorder were poly-substance users. Eighty three percent of the male patients with substance use disorder had poly-substance use disorder.     

Suicide attempts among adolescents in Switzerland: prevalence,associated factors and comorbidity

Switzerland has one of the highest rates of adolescent suicide in Europe, but the prevalence of suicidal thoughts and attempts is unknown. The objective of this paper is to assess the prevalence of suicidal ideation and behaviour among Swiss teenagers and to identify the factors associated with suicide attempts. A self-administered anonymous questionnaire was distributed to a representative sample of 9268 15- to 20-year-old adolescents attending school or college. Six items focused on suicidal ideation and conduct. Multivariate analyses were performed to identify the health variables associated with suicide attempts. About 55% of the adolescents had no suicidal concerns; 26% reported suicidal thoughts, 15% reported suicidal plans and 3% reported suicide attempts. Suicide attempters reported significantly more problems in four areas, namely health behaviour, life events, social relationships and mental health. In conclusion, many factors associated with suicide attempts represent detectable behaviours. Thus health professionals could use this knowledge to be more effective in suicide prevention among adolescents.     

Risk factors for alcohol use among male adolescents and emerging adults in Haiti

This study examined risk factors associated with alcohol use in the past 3 months among young men aged 15-24 in Haiti using data from the 2000 Enquête Mortalité, Morbidité et Utilization des Services. Findings indicate that life-time smoking, multiple sexual partnerships, witnessing inter-parental conflict in childhood, disruption of parental monitoring, and residing in communities with high levels of youth drinking differentiated experimenters from abstainers. Youth out-of-school employment and co-residence with adults who had a history of drunkenness were among risk factors associated with regular alcohol use. The greater was the number of risk factors to which a young man was exposed, the higher were the probabilities of alcohol experimentation and regular use. The findings call for prevention strategies at the family and community levels and for initiatives that focus on sexual and non-sexual individual behaviour change.
