ADHD as a risk factor for early onset and heightened adult problem severity of illicit substance use: An accelerated gateway model

The primary aims of the present study were to assess ADHD history as a risk factor for earlier initiation and current use of licit and illicit substances among a sample of drug using adults. It was hypothesized that ADHD history would accelerate the Gateway Theory of drug use. Participants included 941 drug-using African American and Caucasian individuals in Baltimore, Maryland. The sample consisted of 124 (13.2%) participants who reported a history of ADHD and 817 (86.8%) who reported no history of ADHD. The accelerated gateway hypothesis was supported, as a history of self-reported ADHD was significantly associated with younger ages of initiation for alcohol, cigarettes, marijuana, and cocaine use. Participants with a history of ADHD were also more likely to engage in recent HIV-risk behavior, such as injection drug use and needle sharing. This study provides compelling data in support of an accelerated gateway model for substance use related to ADHD history and increased problem severity in adulthood. Targeted substance use prevention and intervention may be beneficial for those with ADHD.

The Association Between Depressive Symptoms, Anger, and Perceived Support Resources Among Underserved Older HIV Positive Black/African American Adults

By 2015, half of those living with HIV in the United States will be ≥50 years of age. Research suggests that perceived social support is an important factor in maintaining positive health behaviors in this population. The present study examined the relationship between depressive symptoms and trait anger on perceived social support in a sample of low-income HIV positive (HIV+) African Americans ≥50 years of age. Additionally, we examined life stressors moderated the relationship between mental health and perceived support. This study includes 95 HIV+ men and women ≥50 years of age who identify as black/African American. As expected, depressive symptoms and trait anger showed a strong inverse relationship with perceived support resources. Furthermore, life stressors also showed a strong inverse relationship with perceived support. However, life stressors did not moderate the relationship between depressive symptoms and anger. Instead life stressors demonstrated a strong independent relationship with perceived support. The association between depressive symptoms, trait anger, life stressors, and lower perceived support suggests that these factors play a role in ones ability to access needed support resources. Greater perceived support is associated with improved health in HIV+ persons, and may be especially important in tailoring interventions for those ≥50 years of age.

Loneliness and substance use: the influence of gender among HIV+ Black/African American adults 50+

ABSTRACT Estimates suggest 30% of adults report the highest levels of loneliness. Though men are more likely than women to use illicit substances and engage in heavy drinking, the prevalence of substance use in women is growing and their escalation toward dependence occurs more rapidly. Loneliness and substance use have greater relevance within the HIV+ population, with higher rates of substance misuse than the general population. However, the association between loneliness and substance use within HIV+ individuals remains understudied. The purpose of the present study was to test the hypothesis that there would be an association between loneliness and substance moderated by gender in HIV+ older adults. A cross-sectional study was conducted between October 2013 and January 2014. Study participants included 96 HIV-positive Black/African American men and women recruited through the University of Florida Center for HIV/AIDS Research, Education and Service (UF CARES) in Jacksonville, Florida. Participants completed an interviewer-administered assessment examining mental and behavioral health. Pearson correlations examined associations between loneliness and substance use. Binary logistic regression analyses stratified by gender examined the association between loneliness and substance use while controlling for covariates. Among women, loneliness was associated with illicit drug use, AOR = 3.37, 95% CI: 1.23–9.21, p = .018 and heavy drinking, AOR = 2.47, 95% CI: 1.07–5.71, p = .033. No significant associations were found between loneliness and illicit drug use, and heavy drinking in men. Substance use among women in this population may be linked to loneliness. Interventions should be gender specific. Further research into this association is necessary as it will likely have important clinical implications for this population.

Correlates of Trichomonas vaginalis Among Middle Age and Older Adults Who Use Drugs.

Background: Recent studies have reported high rates of Trichomonas vaginalis among middle age and older adults. Though trichomoniasis risk factors in this age cohort remain largely unknown, illicit drug use has been associated with increased incidence of sexually transmitted infections (STIs). The number of mid-older adults using illicit drugs has increased significantly in recent years suggesting the need to understand the relationship between drug use and STIs in this age cohort. Objectives: This study examined the relationship between drug use, sexual-risk behaviors, and biologically confirmed T. vaginalis in a sample of mid-older and younger adults who reported recent drug use. Methods: The cross-sectional design examined the relationship between past 6-month drug use, sexual risk-behaviors, and PCR-confirmed T. vaginalis in 264 adults age 18–64 who were recruited from Baltimore, Maryland. These relationships were also explored in the age-stratified sample among those 18–44 years (“younger”) and individuals 45+ years (“mid-older”). Results: Trichomoniasis prevalence did not differ significantly between younger (18.8%) and mid-older (19.1%) adults. Mid-older adults that tested positive for T. vaginalis were more likely to have used marijuana and crack in the past 6 months. Among younger adults, there were no associations between trichomoniasis and past 6-month drug use and sexual-risk behavior. Conclusions/Importance: Age- and drug-related immune decline is hypothesized to contribute to increase susceptibility to T. vaginalis in mid-older adults. Broad screening for trichomoniasis, particularly among older adults who are often not regarded as at risk for STIs, is needed to control this often asymptomatic infection.

Psychosocial interventions addressing the needs of Black women diagnosed with breast cancer: a review of the current landscape.

Poorer health outcomes and lower survival rates have been well documented among African American/Black (Black) women diagnosed with breast cancer. Black women are 41% more likely to die from breast cancer than White women despite a lower incidence rate. Apart from pharmacotherapy, psychosocial interventions are recommended by the Institute of Medicine as standard medical care for breast cancer patients at all phases of treatment. The current review is the first attempt to systematically evaluate the literature on the influence of psychosocial interventions for Black women diagnosed with breast cancer.

Physical activity in Black breast cancer survivors: implications for quality of life and mood at baseline and 6-month follow-up

The present study sought to examine the influence of physical activity on quality of life and negative mood in a sample of Black breast cancer survivors to determine if physical activity (dichotomized) predicted mean differences in negative mood and quality of life in this population.

Age Cohort Differences in Illicit Drug Use and Hepatitis C Among African American Substance Users

Identifying prognostic indicators for undiagnosed Hepatitis C is crucial to attenuate the negative impact of this disease. This study explored the influence of recent and more distal injection drug use on biologically confirmed Hepatitis C infection among a sample (N = 260) of older and younger African Americans. Data from the baseline assessment of the NEURO-HIV epidemiologic study was analyzed using confounder adjusted regression techniques. Older adults were more likely to test positive for Hepatitis C (OR = 2.80, 95% CI = 1.53–5.11) due to lifetime injection drug use (AOR = 5.37, 95% CI = 3.10–9.28). Clinical implications are discussed.
