Effect of Statin Treatment vs Usual Care on Primary Cardiovascular Prevention Among Older Adults: The ALLHAT-LLT Randomized Clinical Trial

Importance While statin therapy for primary cardiovascular prevention has been associated with reductions in cardiovascular morbidity, the effect on all-cause mortality has been variable. There is little evidence to guide the use of statins for primary prevention in adults 75 years and older. Objectives To examine statin treatment among adults aged 65 to 74 years and 75 years and older when used for primary prevention in the Lipid-Lowering Trial (LLT) component of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT-LLT). Design, Setting, and Participants Post hoc secondary data analyses were conducted of participants 65 years and older without evidence of atherosclerotic cardiovascular disease; 2867 ambulatory adults with hypertension and without baseline atherosclerotic cardiovascular disease were included. The ALLHAT-LLT was conducted from February 1994 to March 2002 at 513 clinical sites. Interventions Pravastatin sodium (40 mg/d) vs usual care (UC). Main Outcomes and Measures The primary outcome in the ALLHAT-LLT was all-cause mortality. Secondary outcomes included cause-specific mortality and nonfatal myocardial infarction or fatal coronary heart disease combined (coronary heart disease events). Results There were 1467 participants (mean [SD] age, 71.3 [5.2] years) in the pravastatin group (48.0% [n = 704] female) and 1400 participants (mean [SD] age, 71.2 [5.2] years) in the UC group (50.8% [n = 711] female). The baseline mean (SD) low-density lipoprotein cholesterol levels were 147.7 (19.8) mg/dL in the pravastatin group and 147.6 (19.4) mg/dL in the UC group; by year 6, the mean (SD) low-density lipoprotein cholesterol levels were 109.1 (35.4) mg/dL in the pravastatin group and 128.8 (27.5) mg/dL in the UC group. At year 6, of the participants assigned to pravastatin, 42 of 253 (16.6%) were not taking any statin; 71.0% in the UC group were not taking any statin. The hazard ratios for all-cause mortality in the pravastatin group vs the UC group were 1.18 (95% CI, 0.97-1.42; P = .09) for all adults 65 years and older, 1.08 (95% CI, 0.85-1.37; P = .55) for adults aged 65 to 74 years, and 1.34 (95% CI, 0.98-1.84; P = .07) for adults 75 years and older. Coronary heart disease event rates were not significantly different among the groups. In multivariable regression, the results remained nonsignificant, and there was no significant interaction between treatment group and age. Conclusions and Relevance No benefit was found when pravastatin was given for primary prevention to older adults with moderate hyperlipidemia and hypertension, and a nonsignificant direction toward increased all-cause mortality with pravastatin was observed among adults 75 years and older.

Demographic trends of binge alcohol use and alcohol use disorders among older adults in the United States, 2005–2014

BACKGROUND Alcohol use is common among older adults, and this population has unique risks with alcohol consumption in even lower amounts than younger persons. No recent studies have estimated trends in alcohol use including binge alcohol use and alcohol use disorders (AUD) among older adults. METHODS We examined alcohol use among adults age ≥50 in the National Survey on Drug Use and Health (NSDUH) from 2005 to 2014. Trends of self-reported past-month binge alcohol use and AUD were estimated. Logistic regression models were used to examine correlates of binge alcohol use and AUD. RESULTS The prevalence of both past-month binge alcohol use and AUD increased significantly among adults age ≥50 from 2005/2006 to 2013/2014, with a relative increase of 19.2% for binge drinking (linear trend p<0.001) and a 23.3% relative increase for AUD (linear trend p=0.035). While males had a higher prevalence of binge alcohol use and AUD compared to females, there were significant increases in both among females. In adjusted models of aggregated data, being Hispanic, male, and a smoker or illicit drug user were associated with binge alcohol use, while being male, a smoker, an illicit drug user, or reporting past-year depression or mental health treatment were associated with AUD. CONCLUSIONS Alcohol use among older adults is increasing in the US, including past-month binge alcohol use and AUD with increasing trends among females. Providers and policymakers need to be aware of these changes to address the increase of older adults with unhealthy drinking.

Exploring Ethnic and Racial Differences in Falls Among Older Adults

Falls are common events that threaten the independence and health of older adults. Studies have found a wide range of fall statistics in different ethnic and racial groups throughout the world. These studies suggest that fall rates may differ between different racial and ethnic groups. Studies also suggest that the location of falls, circumstances of falls, and particular behaviors may also be different by population. Also migration to new locations may alter an individual’s fall risk. However, there are few studies that directly compare ethnic and racial differences in falls statistics or examine how known fall risk factors change based on race and ethnicity. This paper reviews the existing literature on how falls may differ between different racial and ethnic groups, highlights gaps in the literature, and explores directions for future research. The focus of this paper is community dwelling older adults and immigrant populations in the United States.

Shifting characteristics of ecstasy users ages 12–34 in the United States, 2007–2014

BACKGROUND Ecstasy/MDMA has been one of the most prevalent party drugs for decades, and powder ecstasy recently increased in popularity. We examined trends in use to determine who to best target for prevention and harm reduction. METHODS Secondary analysis of the 2007-2014 National Survey on Drug Use and Health, a repeated cross-sectional, nationally representative probability sample, was conducted. Linear trends in past-year ecstasy use and trends in demographic and other past-year substance use characteristics among ecstasy users were examined among participants ages 12-34 (N=332,560). RESULTS Past-year prevalence of ecstasy use was stable across years at 2% (P=0.693). Over time, the proportion of ecstasy users with a college degree increased from 11.5% in 2007/08 to 24.5% in 2013/14 (P<0.001). The proportion of users who were age 12-17 decreased, as did proportions of users who are non-Hispanic black, and reported income <

Older Adults Reporting More Diabetes Mellitus Care Have Greater 9‐Year Survival

20,000/year (Ps<0.001). Prevalence of past-year use of marijuana, LSD, ketamine, and DMT/AMT/Foxy increased among ecstasy users (Ps<0.05); DMT/AMT/Foxy use increased more than four-fold from 2.1% in 2007/08 to 8.7% in 2013/14. Perception of great risk associated with LSD use decreased among users and ease of obtaining LSD increased (Ps<0.05). Past-year use of 5 or more other substances also increased over time (P<0.05). CONCLUSIONS Ecstasy use in the US appears to be increasing among those with college degrees and use of other substances among ecstasy users is growing-particularly use of otherwise rare substances such as tryptamines. Results inform prevention and harm reduction strategies in this increasingly shifting group of ecstasy users.

Prevalence and correlates of binge drinking among older adults with multimorbidity

BackgroundResearch suggests that fall risk among older adults varies by racial/ethnic groups; however, few studies have examined fall risk among Hispanics and Asian American older adults.MethodsUsing 2011–2012 California Health Interview Survey data, this study examines falling ≥2 times in the past year by racial/ethnic groups (Asian Americans, Hispanics, and Blacks) aged ≥65, adjusting for socio-demographic characteristics, body mass index, co-morbidities, and functional limitations. A secondary analysis examines differences in fall risk by English language proficiency and race/ethnicity among Asian Americans and Hispanics.ResultsAsian Americans were significantly less likely to fall compared to non-Hispanic whites, individuals with ≥2 chronic diseases were significantly more likely to fall than individuals with <2 chronic diseases, and many functional limitations were significantly associated with fall risk, when adjusting for all factors. African Americans and Hispanics did not differ significantly from non-Hispanic whites. Analysis adjusting for race/ethnicity and English language proficiency found that limited English proficient Asian Americans were significantly less likely to fall compared to non-Hispanic whites, individuals with ≥2 chronic diseases were significantly more likely to fall than individuals with <2 chronic diseases, and all functional limitations were significantly associated with fall risk, when adjusting for all factors. No differences were found when examining by racial/ethnic and English proficient/limited English proficient groups.ConclusionFurther research is needed to explore factors associated with fall risks across racial/ethnic groups. Culturally relevant and targeted interventions are needed to prevent falls and subsequent injuries in the increasingly diverse aging population in the USA.

Prevention and Screening of Unhealthy Substance Use by Older Adults

BACKGROUND Binge drinking among older adults has increased in the past decade. Binge drinking is associated with unintentional injuries, medical conditions, and lower health-related quality of life. No studies have characterized multimorbidity among older binge drinkers. METHODS We examined past 30-day binge alcohol use and lifetime medical conditions among adults age ≥50 from the National Survey on Drug Use and Health from 2005 to 2014. Self-reported lifetime prevalence of 13 medical conditions and medical multimorbidity (≥2 diseases) among binge drinkers were compared to non-binge drinkers. Multivariable logistic regression models were used to examine correlates of binge alcohol use among older adults with medical multimorbidity. RESULTS Among adults aged ≥50, 14.4% reported past-month binge drinking. Estimated prevalence of medical multimorbidity was lower (21.4%) among binge drinkers than non-binge drinkers (28.3%; p < 0.01). Binge drinkers were more likely to use tobacco and illegal drugs than non-binge drinkers (ps < 0.001). In the adjusted model, among older adults with multimorbidity, higher income (AOR = 1.44, p < 0.05), past-month tobacco use (AOR = 2.55, p < 0.001) and substance use disorder for illegal drugs (AOR = 1.80, p < 0.05) was associated with increased odds of binge alcohol use. CONCLUSION The prevalence of multimorbidity was lower among current binge drinkers compared to non-binge drinkers, possibly because older adults in good health are apt to drink more than adults in poorer health. Current use of tobacco and substance use disorder were associated with an increased risk for binge drinking among older adults with multimorbidity. Binge drinking by older adults with multimorbidity may pose significant health risks especially with the concurrent use of other substances.

Medical multimorbidity and drug use among adults in the United States

The number of older adults who engage in unhealthy substance use is expected to increase substantially to levels never seen before. Older adults, owing to physiologic changes in aging, are at high risk for the adverse effects of alcohol and illegal drug use. Screening and prevention can help older patients to be better informed of the risks of substance use, and reduce high-risk behaviors and its potential negative outcomes. The authors review the prevalence and trends of substance use and their potential impact on health outcomes, and discuss an approach to screening and prevention for older adults.

Use of web-based screening and brief intervention for unhealthy alcohol use by older adults

Adults with medical multimorbidity (≥2 chronic conditions) present challenges for health care systems to provide coordinated care. Substance use can complicate the management of chronic medical conditions, but little research has focused on the intersection of medical multimorbidity and substance use. This study uses cross-sectional analysis of 115,335 adult respondents of the 2012–2014 administrations of the National Survey on Drug Use and Health to estimate the prevalence and correlates of past-year drug use among adults with multimorbidity. The prevalence of past-year drug use was compared between individuals reporting 0, 1, and ≥2 chronic medical conditions. We used multivariable logistic regression to determine correlates of past-year drug use among adults with ≥2 chronic medical conditions. 53.1% reported no chronic conditions, 29.5% reported one chronic condition, and 17.4% reported ≥2 chronic conditions. Past-year drug use was reported by 18.3% of those with no chronic conditions, 14.8% with 1 chronic condition, and 11.6% with ≥2 chronic conditions. Cannabis and opioid analgesics (nonmedical use) were the most common drugs used across all three groups. In the adjusted model, among adults with medical multimorbidity, adults with past-year drug use were more likely to be younger, male, have lower income, and report current tobacco use, alcohol dependence, past-year depression, and having received mental health treatment in the past year. In this national cohort, fewer adults with multimorbidity reported substance use compared to adults with no or one chronic condition, however, this population with high multimorbidity may be particularly vulnerable to the negative effects of drug use.
