What is the association between social integration and mortality risk among African Americans?

Profiles of people cut out in paper

This examination followed over 5,000 African-Americans (until 2018) from the Jackson Heart Study who completed the Berkman-Syme Social Network Index (2000–2004). Watch this 90-second summary of a paper that was published in Social Psychiatry and Psychiatric Epidemiology with HCPDS faculty member Laura Kubzansky, PhD, and incoming Harvard Bell Postdoctoral Fellow Hayami Koga, MD, MPH, PhD, among its authors.

Gut check: Study deepens understanding of link between gut bacteria and emotions

Gut microbiome

HCPDS faculty member Laura Kubzansky, PhD, is a co-corresponding author of a study published in Psychological Medicine that contributes to “gut-brain axis” research by tracking over 200 women, and evaluating their self-reported feelings (as well as how they handled these emotions) along with stool samples. “The analysis found that people who suppressed their emotions had a less diverse gut microbiome. The investigators also found that people who reported happier feelings…

Analysis streamlines measurement of physiological ‘wear and tear’

Tables of biomarkers from study

The measurement of allostatic load (cumulative biological dysregulation related to life course stressors) varies widely across studies, making it difficult to rely on the measurement to help predict mortality. An analysis published in Psychoneuroendocrinology has pinpointed five biomarkers that predict mortality as accurately as more elaborate batteries of tests, enabling the researchers, including Harvard Pop Center Director Lisa Berkman, to offer recommendations for more efficient biomarker collection in future allostatic…

Review of existing racism and housing discrimination research sheds light on how racism impacts population health

Brittney Francis head shot

Harvard Bell Fellow Brittney Francis, PhD, is an author on a paper that reviews and synthesizes the population health scientific literature examining racial discrimination in housing, which is less commonly studied than segregation. Findings point to studies using survey data, as opposed to administrative data, as more likely to reveal an association between exposure to housing discrimination with negative health outcomes.

Diagnosing dementia in rural South Africa using online consensus; cash transfers at earlier age in South Africa to support cognitive health later on; paving the way with promise for genomic studies on cognition in Africa

HAALSI men and women

Three studies by HAALSI researchers based on a rapidly aging population in rural South Africa are contributing to the much-needed scientific literature on global cognitive aging. A study published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring found that a multidisciplinary, web-based consensus conference approach for diagnosing cognitive impairment and dementia in rural South Africa was feasible, and identified the key factors responsible for diagnostic variability among raters. In…

HAALSI study finds improvement in hypertension control in aging South African population

HAALSI men and women

Researchers affiliated with the Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) project have published a study on an aging population in rural South Africa in which more than half suffer from hypertension. Findings reveal that there have been improvements in addressing the condition in every phase of the treatment “cascade” (i.e., awareness, treatment and control).

Harvard Chan School reports: “Study highlights inequalities in early childhood vaccination in India”

Arm of young child with band aids from vaccine

A study published in JAMA Open Network by Harvard Pop Center faculty member S (Subu) V Subramanian, PhD, visiting scientist Rockli Kim, and their colleagues reveals a pattern of vaccination rates among children (ages 12-23 months) in India; despite efforts to achieve increased vaccination rates nationally, the number of children in certain regions and states in India who did not receive routine vaccinations (first dose of the diphtheria-tetanus-pertussis (DTP) vaccine)…
