Predicting steep escalations in alcohol use over the teenage years: age-related variations in key social influences

Aims
This study examined how family, peer and school factors are related to different trajectories of adolescent alcohol use at key developmental periods.

Design
Latent class growth analysis was used to identify trajectories based on five waves of data (from grade 6, age 12 to grade 11, age 17), with predictors at grades 5, 7 and 9 included as covariates.

Setting
Adolescents completed surveys during school hours.

Participants
A total of 808 students in Victoria, Australia.

Measurements
Alcohol use trajectories were based on self-reports of 30-day frequency of alcohol use. Predictors included sibling alcohol use, attachment to parents, parental supervision, parental attitudes favourable to adolescent alcohol use, peer alcohol use and school commitment.

Findings
A total of 8.2% showed steep escalation in alcohol use. Relative to non-users, steep escalators were predicted by age-specific effects for low school commitment at grade 7 (P = 0.031) and parental attitudes at grade 5 (P = 0.003), and age-generalized effects for sibling alcohol use (Ps = 0.001, 0.012, 0.033 at grades 5, 7 and 9, respectively) and peer alcohol use (Ps = 0.041, < 0.001, < 0.001 at grades 5, 7 and 9, respectively). Poor parental supervision was associated with steep escalators at grade 9 (P < 0.001) but not the other grades. Attachment to parents was unrelated to alcohol trajectories.

Conclusions
Parental disapproval of alcohol use before transition to high school, low school commitment at transition to high school, and sibling and peer alcohol use during adolescence are associated with a higher risk of steep escalations in alcohol use.

Regional versus urban differences in teenage alcohol use: Does parental disapproval account for these differences?

Objective: To investigate if parental disapproval of alcohol use accounts for differences in adolescent alcohol use across regional and urban communities. Design: Secondary data analysis of grade-level stratified data from a random sample of schools. Setting: High schools in Victoria, Australia. Participants: A random sample of 10273 adolescents from Grade 7 (mean age=12.51 years), 9 (14.46 years) and 11 (16.42 years). Main outcome measures: The key independent variables were parental disapproval of adolescent alcohol use and regionality (regional/ urban), and the dependent variable was past 30 days alcohol use. Results: After adjusting for potential confounders, adolescents in regional areas were more likely to use alcohol in the past 30 days (OR=1.83, 1.44 and 1.37 for Grades 7, 9 and 11, respectively, P<0.05), and their parents have a lower level of disapproval of their alcohol use (b=-0.12, -0.15 and -0.19 for Grades 7, 9 and 11, respectively, P<0.001). Bootstrapping analyses suggested that 8.37%, 23.30% and 39.22% of the effect of regionality on adolescent alcohol use was mediated by parental disapproval of alcohol use for Grades 7, 9 and 11 participants respectively (P<0.05). Conclusions: Adolescents in urban areas had a lower risk of alcohol use compared with their regional counterparts, and differences in parental disapproval of alcohol use contributed to this difference.

Oral Piercing Complications Among Teenage Students

Purpose: The aim of this study was to assess the use of oral piercings and their possible associated complications among students aged 14 to 18 years.Materials and Methods: A total of 927 students from private and state schools were invited to participate in this study. The participants were subjected to clinical examination, and a questionnaire was provided for collecting the following data: gender, piercing location, oral complications or alterations, and cleaning frequency.Results: Among the students who were analysed, 33 had oral piercings (3.6%); 69.70% were from state schools and 30.30% were from private schools. There was a slight predominance of males (54.55%) compared with females (45.45%). The tongue was the most common location for piercing (66.6%). The complications and alterations associated with the use of piercing were observed in 74.3% of the cases.Conclusions: In the population that was studied, oral piercing was observed in a small percentage of teenage students (3.6%) and there were local complications associated with its use.

Teenage motherhood in Latin America and the Caribbean. Trends, problems and challenges

Teenage motherhood: pregnant with consequences.This issue sets out to show the situation of teenage pregnancy in the Latin American and Caribbean region. The central article draws attention to the persistently high levels of adolescent fertility, which are closely linked to conditions of increased poverty and vulnerability and lead to difficult situations for the young mother, her family and her offspring.

Surgical treatment of type I neuritis in a teenage boy with borderline tuberculoid leprosy

Exacerbation of the immune response against Mycobacterium leprae can lead to neuritis, which is commonly treated via immunosuppression with corticosteroids. Early neurolysis may be performed concurrently, especially in young patients with a risk of functional sequelae. We report the case of a young patient experienced intense pain in the left elbow one year after the treatment of tuberculoid-tuberculoid leprosy. The pain was associated with paresthesias in the ulnar edge and left ulnar claw. After evaluation, the diagnosis was changed to borderline tuberculoid leprosy accompanied with neuritis of the left ulnar nerve. Early neurolysis resulted in rapid reduction of the pain and recovery of motor function.

Addressing teenage pregnancy in rural areas: A case study from Liberty County, Texas

This study explores the issue of teenage pregnancy in a case study of Liberty County, a rural area in Texas with no public health department. It also describes the decision-making process and barriers faced in the beginning phases of adopting a sexual education program, and sets forth an implementation plan for two school districts on disseminating an evidence-based, comprehensive curriculum. Methods include a review of epidemiological data surrounding teenage pregnancy on the national, state, and county level; a literature review of factors related to teenage pregnancy and past interventions implemented in a rural community; a policy review of past and current bills in Legislature; and an analysis of barriers and decision making in implementing an evidence based program through qualitative observations, discussions with community members during meetings, presentations, and discussions. Results of this study indicate that there is a lack of research conducted in rural areas in the field of teenage pregnancy prevention and sexual education programs. Barriers experienced in Liberty County are shown to be consistent in scientific literature such as funding, logistical issues, and problems approaching the School Board in adopting a comprehensive sexual education program. This study fills a large gap in the literature on rural adolescents and attempts to analyze the process of decision-making in a rural area related to adoption of sexual education programming. In order to relieve this health disparity, further research should focus on rural areas to gain insight on the attitudes and behaviors of rural adolescents and beliefs among community stakeholders.^
