Developmental trajectories of adolescent cannabis use and their relationship to young adult social and behavioural adjustment: a longitudinal study of Australian youth

This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n=852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12.

Higher adherence to the Australian dietary guidelines is associated with better mental health status among Australian adult first-time mothers

Background: Mental health disorders are a leading cause of disability worldwide, including in first-time mothers. Understanding the associations between diet and depressive symptoms could assist in improving mental health status in this group. Objective: Our aim was to determine the association between diet quality, fruit, vegetable, and fish consumption and depressive symptoms in first-time mothers aged 19 to 45 years.

Design: We analyzed cross-sectional, baseline data (3 months postpartum) from the Melbourne InFANT (Infant Feeding, Activity, and Nutrition Trial) Extend Program.

Participants/setting: Participants were first-time Australian mothers aged 19 to 45 years from the Geelong and Melbourne regions of Victoria, Australia (n=457).

Main outcome measures: A self-administered, 137-item food frequency questionnaire assessed dietary intake over the past year. Adherence to the 2013 Australian Dietary Guidelines was assessed using the Dietary Guideline Index as a measure of diet quality. Depressive symptoms were determined using the Center for Epidemiologic Studies Depression Scale.

Statistical analysis performed: Relationships between diet quality, fruit, vegetable, and fish intake and depressive symptoms were investigated using linear regression adjusted for relevant covariates (age, smoking status, sleep quality, education, physical activity status, and body mass index).

Results: Better diet quality, as indicated by a higher score on the Dietary Guideline Index, was associated with lower depressive symptoms after adjusting for relevant covariates (β=-.034; 95% CI -.056 to -0.012). There were no other associations between dietary intake and depressive symptoms.

Conclusions: Adherence to the Australian Dietary Guidelines was associated with better mental health status among first-time mothers. Further research, including longitudinal and intervention studies, are required to determine causality between dietary intake and depressive symptoms, which might help inform future public health nutrition programs for this target group.

Optimising the impact of education for community pharmacy in Australia

Aims & rationale/Objectives : This paper examines the extent to which different models of community pharmacist continuing education (CE) are evidence-based. It also describes the impact of varying education models on attendance and attitudes within the profession.

Methods : A literature review was conducted to establish principles that should be applied to health professional education, and pharmacy in particular. Interviews were conducted with representatives from four organisations involved in the education of pharmacists to understand their current models. Four focus groups were held with community pharmacists to understand their educational experiences and attitudes.

Principal findings : The purpose of CE is to improve the clinical performance of health practitioners. Literature examining outcomes from CE underlines the importance of adult learning principles. Focus groups supported the view that consideration of these principles is beneficial. These principles, including problem-based learning, clinical applicability, relevance, and active involvement in the learning process, are currently incorporated into educational models to varying extents. Access problems such as cost, distance, insufficient flexibility in delivery, and poor promotion of educational opportunities prevent many pharmacists from taking responsibility for their own learning. A lack of appropriate assessment by some registering authorities is counterproductive to achieving CE outcomes in clinical practice. Participants already engaged in continuing professional development (CPD) agreed with the principles of its introduction.

Discussion : Optimising outcomes from CE requires considerable input from numerous stakeholders. The recent introduction of mandatory pharmacist CPD across Australia should encourage an individual focus on learning outcomes. Focus group participants are likely to be education enthusiasts and may not represent the views of the entire profession.

Implications : This study identifies the need for a system-wide approach for achieving outcomes from CE. It is therefore advisable that a coordinated strategy be developed by all stakeholders for education delivery so as to optimise the impact of CE.

Homebirds: re-conceptualising music in young adult LGBTQ fiction

This thesis identified how musical references in young adult LGBTQ fiction can function as ideological apparatuses. The research critiqued and re-imagined the ways music might be utilised in young adult fiction to facilitate a better recognition of how such references can underpin readers’ engagement with the identity politics of young adult LGBTQ narratives.

Young children's everyday concepts about the internet: Implications for cyber-safety education in the early years

Young children from around the world are accessing the internet in ever increasing numbers. The rapid increase in internet activity by children aged 4–5 years in particular is due to the ease access enabled them by touchscreen internet-enabled tablet technologies. With young children now online, often independently of adult supervision, the need for early childhood cyber-safety education is becoming urgent. In this paper, we report the early findings from a project aimed at examining the development of cybersafety education for young children. We argue that cyber-safety education for young children cannot be effectively developed without first considering young children’s thinking about the internet. In this paper, we use Vygotsky’s ideas about the development of mature concepts from the merging of everyday and scientific concepts. We identify the potential range of everyday concepts likely to form the basis of young children’s thinking about the internet as a platform for cyber-safety education in the early years.
