The association of perceived discrimination with dementia risk in Black older adults.

INTRODUCTION: Non-Hispanic Black, compared to non-Hispanic White, older adults are at increased risk for dementia. This may be due partly to greater exposure to psychosocial stressors, such as discrimination; however, few studies have examined this association. METHODS: We examined the association of perceived discrimination (e.g., everyday, lifetime, and discrimination burden) with dementia risk in 1583 Black adults co-enrolled in the Atherosclerosis Risk in Communities (ARIC) Study and the Jackson Heart Study (JHS). Perceived discrimination (defined continuously and using tertiles) was assessed at JHS Exam 1 (2000-2004; mean age ± SD:66.2 ± 5.5) and related to dementia risk through ARIC visit 6 (2017) using covariate-adjusted Cox proportional hazards models. RESULTS: Associations of perceived everyday, lifetime, and burden of discrimination with dementia risk were not supported in age-adjusted models or demographic- and cardiovascular health-adjusted models. Results were similar across sex, income, and education. DISCUSSION: In this sample, associations between perceived discrimination and dementia risk were not supported. HIGHLIGHTS: In Black older adults perceived discrimination not associated with dementia risk. Younger age and greater education linked to greater perceived discrimination. Older age and less education among factors associated with dementia risk. Factors increasing exposure to discrimination (education) are also neuroprotective.

Institutional-level drivers of gender-inequitable scientific career progression in sub-Saharan Africa.

BACKGROUND: This study sought to determine how institutional environments, including values, policies, and their implementation, shape inequities in scientific career progression for women and men, and their disadvantages in relation to their multiple social identities in sub-Saharan Africa (SSA). The findings are drawn from a wider research study that was aimed at gaining an in-depth understanding of the barriers and enablers of gender-equitable scientific career progression for researchers in SSA. This was nested within the context of the Developing Excellence in Leadership, Training and Science in Africa (DELTAS Africa) programme-a health-based scientific research capacity-strengthening initiative. METHODS: The study adopted an exploratory qualitative cross-sectional study design. In-depth interviews (IDIs) with trainees/research fellows at various career stages supported and/or affiliated to three purposively selected DELTAS Africa Research Consortia were the main method of data collection. In addition, key informant interviews (KIIs) with consortia research leaders/directors, co-investigators, and the consortia management team were also conducted to corroborate information gathered from the IDIs, and also to provide additional insights on the drivers of intersectional gender-inequitable career progression. In total, 58 IDIs (32 female and 26 male) and 20 KIIs (4 female and 16 male) were conducted. The interviews were carried out in English between May and December 2018. The data were analysed inductively based on emergent themes. RESULTS: Three interrelated themes were identified: first, characterization of the institutional environment as highly complex and competitive with regard to advancement opportunities and funding structure; second, inequitable access to support systems within institutions; third, informal rules-everyday experiences of negative practices and culture at the workplace, characterized by negative stereotypical attitudes, gender biases, sexual harassment, and bullying and intimidation. CONCLUSIONS: We contend that understanding and addressing the social power relations at the meso-institutional environment and macro-level contexts could benefit career progression of both female and male researchers by improving work culture and practices, resource allocation, and better rules and policies, thus fostering positive avenues for systemic and structural policy changes.

Exploring Teen Suicide Rates through the Lens of Macro Risk Factors.

As the second leading cause of death in teenagers, suicide has been a consistent public health issue for the past decade. Our goal is to understand the relationship between increasing teen suicide rates by state policies. We explore links between macro-level risk factors and state suicide rates. Risk factors explored include state behavioral health spending, child access policies for firearms, insurance coverage, tax revenue from tobacco and alcohol, school spending per pupil, pupil support services funding, and teacher spending. This research shows a relationship between pupil support spending, any child access law, required legislation, and lower teen suicide rates. The results from this study can aid in the understanding of macro-level influences on teen suicide; empowering advocates, lawmakers, and researchers to develop informed interventions and policies. Increasing multi-level understanding around suicide can provide an opportunity to slow or stop suicide rates.
