Global Prevalence of Adolescent Use of Nonprescription Weight-Loss Products: A Systematic Review and Meta-Analysis.

Importance: Use of nonprescribed weight-loss products in adolescents is a public health concern that is associated with negative physical and psychological consequences. However, the prevalence of nonprescribed weight-loss product use in adolescents is unknown.

Objective: To determine the global prevalence of nonprescription weight-loss product use in children and adolescents.

Measuring the importance of different barriers to opioid agonist treatment using best-worst scaling in an Australian setting.

Objective: Opioid agonist treatment (OAT) is an effective treatment for opioid use disorder (OUD), however several client barriers to OAT are reported. Client importance of these barriers using economic preference elicitation measures have not been identified. This paper determines the most important OAT barriers using best-worst scaling (BWS) and compares the results of BWS to Likert scale.

Identifying the most common barriers to opioid agonist treatment in an Australian setting.

Background: Opioid use disorder is a public health concern in Australia. Opioid agonist treatment (OAT) is effective at treating and minimising harm from opioid use disorder, yet is underused in Australia due to client barriers. Although these barriers have been reported, the barriers that are most important to clients is unclear.

The impact of loneliness and social isolation on health state utility values: a systematic literature review.

Background: Loneliness and social isolation are recognised as social problems and denote a significant health burden. The aim of this study was to conduct a systematic literature review to explore the health state utility values (HSUVs) associated with loneliness and/or social isolation.

Method: Peer-reviewed journals published in English language that reported both HSUVs along with loneliness and/or social isolation scores were identified through five databases.

Barriers to accessing opioid substitution treatment for opioid use disorder: A systematic review from the client perspective.

Objectives: To update the existing evidence to identify specific barriers to initiation of opioid substitution therapy (OST) for those with opioid use disorder (OUD).

Methods: The review follows Preferred Reporting Items for Systematic Reviews andMeta-Analyses (PRISMA) guidelines. Six databases were initially searched in November 2019, with the search updated on 11 November 2020, for qualitative or quantitative studies reporting the barriers to initiating OST from the client with OUD perspective.
