Adolescent Marijuana Use

Abstract To investigate temporal patterns, socio-demographic gradients, and structural breaks in adolescent marijuana use in the United States from 1991 to 2018, we used hierarchical Age-Period-Cohort logistic models to separate temporal effects of marijuana use among 8th, 10th, and 12th graders from 28 waves of the Monitoring the Future survey. Structural breaks in period effects were further detected via a dynamic-programing-based method. Net of other effects, we found a clear age-related increase in the probability of marijuana use (10.46%, 23.17%, and 31.19% for 8th, 10th and 12th graders, respectively). Period effects showed a substantial increase over time (from 16.23% in 2006 to 26.38% in 2018), while cohort effects remained stable over the period of study. Risk of adolescent marijuana use varied by sex, racial group, family status, and parental education. Significant structural breaks during 1995–1996, 2006–2008, and 2011–2013 were identified in sub-populations. A steady increase in marijuana use among adolescents over the latter years of this time period was identified. Adolescents who were male, non-Black, lived in non-intact families, and who had less educated parents were especially at risk of marijuana usage. Trends of adolescent marijuana use changed significantly during times of economic crisis.

The emergence of age-related chronic diseases within the United States has led to the direct increase of Alzheimer’s disease (AD) as well as other neurological diseases which ultimately contribute to the development of dementia within the general population. To be specific, age-related chronic diseases such as cardiovascular disease, high cholesterol, diabetes, and kidney disease contribute greatly to the advancement and rapid progression of dementia. Furthermore, unmodifiable risk factors such as advancing age and genetics as well as modifiable risk factors such as socioeconomic status, educational attainment, exercise, and diet further contribute to the development of dementia. Current statistics and research show that minority populations such as Hispanic Americans in the United States face the greatest burden of dementia due to the increase in the prevalence of overall population age, predisposing genetics, age-related chronic diseases, low socioeconomic status, as well as poor lifestyle choices and habits. Additionally, Hispanic Americans living within Texas and the rural areas of West Texas face the added challenge of finding appropriate healthcare services. This article will focus upon the research associated with AD as well as the prevalence of AD within the Hispanic American population of Texas and rural West Texas. Furthermore, this article will also discuss the prevalence of age-related chronic diseases, unmodifiable risk factors, and modifiable risk factors which lead to the progression and development of AD within the Hispanic American population of the United States, Texas, and rural West Texas.

Lyme disease is the most common vector-borne disease in the United States and is characterized by a bimodal age distribution and male predominance. We examined trends in reported cases during a 25-year period to describe changes in the populations most affected by Lyme disease in the United States. We examined demographic characteristics of people with confirmed cases of Lyme disease reported to the Centers for Disease Control and Prevention during 1992-2016 through the National Notifiable Diseases Surveillance System. We grouped cases into 5-year periods (1992-1996, 1997-2001, 2002-2006, 2007-2011, 2012-2016). We calculated the average annual incidence by age and sex and used incidence rate ratios (IRRs) to describe changes in Lyme disease incidence by age and sex over time. We converted patient age at time of illness into patient birth year to ascertain disease patterns according to birth cohorts. The incidence of Lyme disease in the United States doubled from 1992-1996 to 2012-2016 (IRR = 1.74; 95% CI, 1.70-1.78) and increased disproportionately among males; IRRs were 39%-89% higher among males than among females for most age groups. During the study period, children aged 5-9 years were most frequently and consistently affected. In contrast, the average age of adults with Lyme disease increased over time; of all adults, people born during 1950-1964 were the most affected by Lyme disease. Our findings suggest that age-related behaviors and susceptibilities may drive infections among children, and the shifting peak among adults likely reflects a probability proportional to the relative size of the baby boom population. These findings can inform targeted and efficient public health education and intervention efforts.

Living With Hiv

The HIV (human immunodeficiency virus) epidemic in the United States remains a serious public health concern. Despite treatment and prevention efforts, approximately 50,000 new HIV cases are transmitted each year. Estimates indicate that 44% of all people diagnosed with HIV are living in the southern region of the United States. African Americans represent 13.2% of the United States population; however, 44% (19,540) of reported new HIV cases in 2014 were diagnosed within this ethnic group. The majority of cases were diagnosed in men (73%, 14,305). In the United States, it is estimated that 21% of adults living with HIV are 50 years or older. There exists limited data regarding how well African American men are aging with HIV disease. The purpose of this study was to explore the perceptions and experiences of older African American men living with HIV in rural Georgia. Data were collected from 35 older African American men living with HIV using focus groups and face-to-face personal interviews. Qualitative content analysis revealed six overlapping themes: (1) Stigma; (2) Doing Fine, Most of the Time; (3) Coping With Age-Related Diseases and HIV; (4) Self-Care; (5) Family Support; and (6) Access to Resources. The findings from this study provide new insights into the lives of rural HIV-infected African American men, expands our understanding of how they manage the disease, and why many return to or remain in rural communities.

Medical Marijuana Use

Marijuana is one of the most widely used recreational substances in the United States, with high rates of use during peak childbearing years. Medical marijuana use is also becoming more widely accepted in the United States, with legalization in 17 states and the District of Columbia. The available literature suggests that maternal marijuana use during breastfeeding is associated with potentially negative outcomes for infants and children. Adverse effects can include feeding difficulty, lethargy, and delayed cognitive and motor development. Mothers considered heavy or chronic users of marijuana are advised to not breastfeed infants. The aim of this article is to examine the prevalence of marijuana use, the potential effects on breastfed infants, and current recommendations from lactation experts.
