Aiming to ward off ‘spiral of decline’ in aging rural South African population

Researchers analyzed data collected as part of the HAALSI study to learn more about the self-reported physical activity (PA) levels of a population over 40 years old. Factors such as being male, over the age of 80, in a higher wealth category, obesity, and poorer functional capacity correlated with lower levels of physical activity. The … Continue reading “Aiming to ward off ‘spiral of decline’ in aging rural South African population”

A hopeful discovery about later-life cognitive function in those exposed to early-life adversity in rural South Africa

The HAALSI team of researchers is one of the first to look at the impacts of early-life adversity (such as parental unemployment, discord and substance abuse, and physical abuse) on later-life cognitive function in rural South Africa. Their findings published in Psychology and Aging suggest that cognitive function is, for the most part, resilient against … Continue reading “A hopeful discovery about later-life cognitive function in those exposed to early-life adversity in rural South Africa”

Is social capital valuable in protecting cognitive function in lower-resource settings such as rural South Africa?

While theories about the connection between strong social supports and better cognitive health among an aging population are well established in higher resource settings (high income, high education levels), less is known about whether this same pattern exists in lower resource settings. Researchers affiliated with Health and Aging in Africa: a Longitudinal Study of an … Continue reading “Is social capital valuable in protecting cognitive function in lower-resource settings such as rural South Africa?”

How can diabetes be more accurately diagnosed in an aging South African population?

Two of the most common tests for diagnosing diabetes (fasting plasma glucose and HbA1c) don’t always yield the same result, and researchers affiliated with the research study Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) took a closer look at the concordance of these test results within … Continue reading “How can diabetes be more accurately diagnosed in an aging South African population?”
