African Studies on Aging and Noncommunicable Diseases Epidemiology

Plain-language summary

Despite the rising burden of noncommunicable diseases (NCDs), including cardiovascular diseases (CVDs), across Africa, high-quality evidence on the distribution of NCDs and their risk factors remains strikingly scarce. Many global estimates continue to rely on limited empirical data from African countries, and this persistent data gap has led major international research collaborations to underrepresent the continent. This reality highlights an urgent need for granular, context-specific, and methodologically robust data on NCDs and their determinants across Africa. The African Studies on Ageing and Noncommunicable Disease Epidemiology (ASANDE) initiative responds directly to this need by assembling harmonized, individual-level datasets from African populations, complemented by comparable data from other global regions. With recruitment underway, ASANDE seeks to quantify and compare the associations between major NCD risk factors, including cardiometabolic, behavioral, and environmental determinants, and the incidence and mortality of major NCD outcomes (cardiovascular diseases, cancer, chronic respiratory diseases, diabetes, and other NCDs) across world regions, with a particular emphasis on disparities between African populations and the rest of the global population.

\- Inclusion criteria We included cross-sectional surveys and longitudinal population-based studies providing individual-level data on established noncommunicable disease (NCD) risk factors, including body-mass index, systolic blood pressure, non-high-density lipoprotein cholesterol, current smoking status, and diabetes mellitus, together with information on predefined NCD outcomes of interest (including cardiovascular diseases, cancer, chronic respiratory diseases, and other major NCDs). For longitudinal studies, prospective ascertainment of incident events and mortality was required. \- Exclusion criteria Participants were excluded if they were younger than 18 years at the time of assessment, had missing data on the outcome of interest, had no available information on the exposure variables (NCD risk factors), or, for longitudinal analyses, had a documented history of the respective NCD outcome at baseline.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
