简要总结
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.

入选标准
- •- 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.
排除标准
- •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.
结局指标
主要结局
non communicable diseases
时间窗: Median follow-up of approximately 10 years across cohorts.
Event rates of noncommunicable diseases (NCDs) and NCD subtypes: First fatal or non-fatal diagnosis of cardiovascular diseases (including myocardial infarction, unstable angina, coronary revascularization, ischemic or hemorrhagic stroke), cancer, chronic respiratory diseases (including chronic obstructive pulmonary disease and asthma), type 2 diabetes mellitus, chronic kidney disease, or other major NCD-related outcomes, as well as NCD-related or unclassifiable death. The type of outcome measurement varies across cohorts. NCD cases and subtypes are assessed through self-reported questionnaire information, clinical examinations, medical record validation, national hospital discharge registry data, disease-specific registries (e.g., cancer registries), causes of death registry data, or central death registries, depending on the study protocol of the respective cohort studies.
