Changes in and correlates of cannabis-involved substance use treatment admissions age 50 and older, 2000–2021
Background and aims: Cannabis use among U.S. older adults has risen rapidly over the past two decades. This study examined the changes in and correlates of cannabis-involved substance use treatment admissions among this demographic. Methods: =5,593,004), we fitted joinpoint regression models to examine changes in the percent of cannabis-involved admissions of all substance use admissions. We used multinomial and binary logistic regression models …
Associations of medical outcomes with substances involved in suicide attempt cases age 50 and older reported to U.S. Poison Centers, 2016–2023
Background and aims: After a slight decline in suicide rates during the COVID-19 pandemic, suicide rates and suicide attempts in the U.S. have been increasing again in 2022 and 2023. Compared to younger age groups, the 50+ age group has significantly higher rates of serious medical outcomes from suicide attempts. In this study, we examined the medical outcome severities associated with different classes of substances involved in suicide attempt c…
Mental Health Treatment Use, Perceived Treatment Need, and Reasons for Non-Use Among U.S. Adults with Serious Suicidal Thoughts During the Covid-19 Pandemic
Perceived Risk of Binge Drinking among Older Alcohol Users
Despite the high prevalence of alcohol use and binge drinking among older adults, little research has been conducted on the association between their alcohol risk perception and alcohol use patterns. Using data on past-year alcohol users aged 50 and older (N = 6693) in the 2022 National Survey on Drug Use and Health, we examined the (1) associations between risk perception of binge alcohol use 1-2 times a week and alcohol use frequency, binge use…
Associations between Cannabis Consumption Methods and Cannabis Risk Perception
Given diversified cannabis products, we examined associations between cannabis consumption methods and cannabis risk perception of smoking cannabis 1-2 times a week. Using the 2022 U.S. National Survey on Drug Use and Health data (N = 12,796 past-year adult cannabis users; M = 6127 and F = 6669), we used multinomial and binary logistic regression models. Smoking was the most prevalent method, followed by eating/drinking, vaping, and dabbing. One-…
Serious suicidal thoughts, suicide plans, and mental health service use among youth during the Covid-19 pandemic
Firearm use risk factors and access restriction among suicide decedents age 75 and older who disclosed their suicidal intent
Background and aims: A majority of older adult suicide decedents used firearms. In this study, we focused on suicide decedents age 75+ who disclosed their suicidal intent within a month of their injury/death to examine demographic and clinical characteristics associated with firearm use and firearm access restriction attempts by their family members. Methods: = 1,734 suicidal intent disclosers; 1,476 males and 258 females; 21.4% of decedents age …
Three leading suicide methods in the United States, 2017–2019
Background and aims: The U.S. suicide data show that use of lethal methods, specifically firearms and hanging/suffocation, has been increasing among young and middle-aged adults of both sexes over the past decades. In this study, we examined demographic and clinical correlates of use of firearms, hanging/suffocation, and poisoning as suicide methods among suicide decedents age 18+. Methods: = 94,454, age ≥ 18 at the time of suicide; 74,042 men an…
Job loss, financial strain, and housing problems as suicide precipitants
Previous research has shown that job loss, financial strain, and/or loss of housing (JFH) in midlife elevate suicide risk. In this study based on the 2017-2019 National Violent Death Reporting System, we examined other suicide precipitants and contributors of decedents whose suicide was in part precipitated by JFH and the circumstances under which they died. First, we examined all adult decedents (N = 94,454; 74,042 males [78.4%] and 20,412 femal…
Psychological Distress, Cannabis Use Frequency, and Cannabis Use Disorder Among US Adults in 2020
Using 2020 National Survey on Drug Use and Health data (N = 27,170, age 18+), we examined associations of psychological distress with: (1) cannabis use frequency among all adults, and (2) cannabis use disorder (CUD) among cannabis users. Of all adults, 18.2% reported past-year cannabis use, 12.9% reported mild-moderate psychological distress, and 12.9% reported serious psychological distress. Greater proportions of cannabis users, especially thos…
Suicidal intent disclosure among adult suicide decedents
Research on who does/does not disclose suicidal intent (SI) and related factors has important implications for suicide risk management. In this paper based on the 2017-2019 National Violent Death Reporting System, we compared four age groups (18-24, 25-44, 45-64, and 65+ years) of suicide decedents with respect to associations between SI disclosure and (1) suicide contributing/precipitating factors, and (2) suicide means. The results shows that t…
Demographic and Clinical Correlates of Treatment Completion among Older Adults with Heroin and Prescription Opioid Use Disorders
In this study using 2015-2018 Treatment Episode Data Set-Discharge (TEDS-D) cases age 55+ for heroin (N = 101,524) or prescription opioids (PO; N = 25,510) as the primary substance, we examined treatment completion rates and correlates. We fit separate logistic regression models for heroin and PO cases with treatment completion status (completed vs. discontinued due to dropout/termination/other reasons) for each treatment setting (detoxification,…
Unmet Healthcare Needs and Healthcare Access Gaps Among Uninsured U.S. Adults Aged 50–64
Lack of health insurance (HI) is a particular problem for near-older Americans aged 50-64 because they tend to have more chronic health conditions than younger age groups and are at increased risk of disability; however, little recent research has focused on HI coverage and healthcare access among this age group. Using the U.S. National Health Interview Survey data for the years 2013 to 2018, we compared HI coverage and healthcare access between …
Emergency Department Visits and Overnight Hospital Stays among Persons Aged 50 and Older Who Use and Misuse Opioids
Opioid misuse and adverse health outcomes are serious problems among the 50+ age group. Using data from the 2015-2016 National Survey of Drug Use and Health (N = 17,608 respondents aged 50+), we examined emergency department (ED) visits and hospitalizations among those who reported (1) no opioid use in the past year (61.4%); (2) opioid use but no misuse (36.0%); and (3) opioid misuse (2.6%). Compared to nonusers, those who reported use but no mis…
Association between Nonmedical Marijuana and Pain Reliever Uses among Individuals Aged 50
Marijuana and pain reliever use for medical and nonmedical purposes has been increasing among older adults. Using the 2012-2013 U.S. National Survey on Alcohol and Related Conditions (NESARC-III), this study examined: (1) the association between past-year nonmedical marijuana and pain reliever use among adults aged 50+ years (N = 14,715); and (2) sociodemographic, health, and pain-related correlates of nonmedical marijuana and/or pain reliever us…
