The impacts of COVID-19 measures on drug markets and drug use among a cohort of people who use methamphetamine in Victoria, Australia.

BACKGROUND AND AIMS: Few studies of the impacts of the coronavirus disease 2019 (COVID-19) public health measures on drug markets and drug use patterns have used longitudinal data. We aimed to examine whether COVID-19 measures were associated with increases in methamphetamine price, decreases in methamphetamine use frequency and subsequent changes in secondary outcomes of other drug use frequency in metropolitan Melbourne and regional Victoria. DESIGN: Longitudinal analysis framework was used from a longitudinal cohort of people who use methamphetamine. SETTING: Victoria state, Australia. PARTICIPANTS: One hundred eighty-five VMAX study participants who reported a methamphetamine purchase after the onset of the pandemic were used for the price paid analysis. Methamphetamine or other drug use frequency analysis was performed using 277 participants who used methamphetamine during the pandemic or in the year before the pandemic. MEASUREMENTS: Price paid per gram of methamphetamine derived from the most recent purchase price and most recent purchase quantity. Frequency of methamphetamine and other drug use measured as the average number of days per week used in the last month. FINDINGS: Compared with pre-COVID-19 period, methamphetamine prices increased by AUD351.63 (P value <0.001) and by AUD456.51 (P value <0.001) in Melbourne and regional Victoria, respectively, during the period in which the most intense public health measures were implemented in Victoria. Although prices decreased after harder restrictions were lifted (by AUD232.84, P value <0.001 and AUD263.68, P value <0.001, in Melbourne and regional Victoria, respectively), they remained higher than pre-COVID-19 levels. A complementary 76% decrease was observed in relation to methamphetamine use frequency in regional Victoria (P value = 0.006) that was not offset by any changes in the frequency of use of other drugs such as alcohol, tobacco or other illicit drugs. CONCLUSION: COVID-19 public health measures in Victoria state, Australia, appear to have been associated with major price changes in the methamphetamine market and decreased frequency of use of the drug.

Returning to the nest: Emerging adults living with parents during the COVID-19 pandemic.

Changes in the working, study and social lives of emerging adults due to the COVID-19 pandemic have led to greater need for external supports. Many who lived independently may have sought that support by returning to live with parents. This study identifies factors associated with returns made between 2019 and 2020. It describes supports needed and obtained, relationships between parents and their resident emerging adults and identifies correlates of poor coping and high psychological distress. Data from the Longitudinal Surveys of Australian Youth and the Longitudinal Study of Australian Children were used and showed half of the emerging adults who moved did so due to COVID-19 restrictions. Loss of work and increased need for emotional and financial support were key drivers of moves. Nineteen per cent who returned found spending more time with family difficult and over half did not have their support needs fully met, increasing their odds of poor coping at that time (OR = 2.9, 4.3, respectively) and subsequent psychological distress (OR = 6.0). Families were an important source of support but could not necessarily mitigate all challenges; for some emerging adults, returning to live with parents gave rise to additional difficulties which negatively affected mental health.

Depressive symptoms and social support among Australian men: A 7-year longitudinal study.

BACKGROUND: Mental health disorders are ranked globally as the single largest contributor to non-fatal ill-health. Social support can be a means of reducing and managing depression. However, depression can also impact on a person's level of social support. OBJECTIVE: As men typically have fewer sources of social support than females, this study investigated the bi-directional associations between depressive symptoms and perceived levels of social support among Australian males, aged 18-63. METHODS: Three waves of panel data from Ten to Men: The Australian Longitudinal Study on Male Health collected over 7 years (2013-2020) were used. A random intercept cross-lagged panel analysis with 5112 participants was undertaken. Mediating effects and indirect and total effects for lagged and cross-lagged pathways were also examined. RESULTS: Over time, greater social support was found to be associated with lower depression levels, and simultaneously greater levels of depression was found to be associated with lower levels of social support. Standardised cross-lagged effects between waves were mostly similar (ß = 0.10). However, mediation analyses identified that only the total effect size of the association for depression at wave 1 predicting social support at wave 3 (ß = -0.29) was significant. Mediated effects of social support at wave 1 predicting depression at wave 3 were not significant. LIMITATIONS: These include the number of years between each wave, and data were collected during the COVID pandemic. CONCLUSION: The study provides robust longitudinal evidence supporting the notion that social support and depression are both a cause and consequence of the other. However, the long-term effects of depression reducing social support were longer lasting than the effects of social support reducing depression.
