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

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

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).

HAALSI study evaluates less expensive and easier to implement method to assess salt consumption at the population level in rural South Africa

South Africa has introduced regulations to reduce sodium in processed foods. Researchers affiliated with the HAALSI study have found that spot urine samples, a less expensive (and less complicated) method of assessing salt consumption, are a viable alternative to the standard 24-h urine collection method for evaluating the population median 24hrUNa excretion. The findings, published in the Journal of Hypertension, “could play an important role for governments and public health…

Antiretroviral therapy (and resulting increased viral suppression) linked to longer AND healthier lives for older adults in South Africa

Researchers affiliated with the HAALSI study, including former Harvard Bell Fellows Collin Payne, PhD, and Lindsay Kobayashi, PhD, and faculty member Jennifer Manne-Goehler, PhD, are among the authors of a study published in The Lancet HIV that links increased viral suppression at the population level with not only increased life expectancy, but also with less disability, pointing to the value of ART to foster healthy aging. Learn more in this…

Study of aging population in South Africa finds that HIV viral suppression through ART is leveling the field of healthy longevity

Findings by HAALSI researchers published in The Lancet Healthy Longevity, a special issue of conference abstracts, point to similar levels of increased lifespan and “healthspan” among those HIV-positive individuals who achieved viral suppression through ART as observed among HIV-negative individuals.

What affects the mental health of a population that is now growing older in sub-Saharan Africa?

Harvard Pop Center Director of Research & Research Scientist Elyse Jennings, recent Harvard Bell Fellow Leslie Adams, and senior data scientist at the University of Cape Town Chido Chinogurei have co-authored a study published in Social Science & Medicine – Mental Health (SSM-MH) that found that experiencing a marital dissolution was associated with more depressive symptoms than remaining married for both men and women, and men (but not women) reported greater…

Older adults in rural South Africa who care for their grandchildren may also be safeguarding their cognitive function

Two older women walk on a dirt road in rural South Africa

Three researchers (Harvard Pop Center Research Scientist Elyse Jennings, Research Associate Director Meagan Farrell, and former Bell Fellow Lindsay Kobayashi) affiliated with one of the flagship projects at the Harvard Pop Center — Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) — have published their findings in the Journal of Aging and Health.

Latest study on aging in South Africa presents some of the first incidence rates of aging-related cognitive impairment in this population

An older South African man and a healthcare worker do an intake sitting outside in rural South Africa

HAALSI researchers — including former Harvard Bell Fellow Lindsay Kobayashi, and Harvard Pop Center Research Associate Meagan Farrell, and Director Lisa Berkman — have published a study that finds similar patterning between social disparities (such as differences in formal education, literacy and marital status) and cognitive impairment rates in rural South Africa as observed in many high-income countries.
