Biomarkers are directly-measured biological indicators of disease or health. In population and social sciences, biomarkers need to be easy to obtain, transport, and analyze. Dried Blood Spot (DBS) collection meets this need, can be collected in the field with high response rates and analyzed for a variety of biomarkers.

Conservation of Small Populations

2019
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Population Growth - Concepts

Population Models An ecological population is a group of individuals of a single species living in an area at the same time. To persist, a population must either grow or maintain its size. Population ecology is the study of how population size and age distribution change over time through interactions with other species and the environment as well as with individuals of their own species. A particularly important feature that is studied by ecologists is the rate at which a population grows or...

Commercial smartwatches equipped with wearable sensors are increasingly being used in population studies. However, their utility is often constrained by their limited battery duration, memory capacity, and data quality. This report provides examples of cost-effective solutions to real-life technical challenges encountered during studies involving asthmatic children and elderly cardiac patients.
FAQs
Risk stratification organizes patients into groups according to patterns of risk identified from clinical data and related health information. This allows care teams to distinguish populations needing preventive services, chronic disease management, or coordinated interventions. The approach helps direct attention and resources toward defined patient groups rather than applying the same strategy to everyone.
Examining how outcomes are distributed reveals whether health benefits and burdens are shared evenly across groups. When clinical findings are considered alongside behaviors, environments, social conditions, and access to care, analysts can identify risk factors and preventable disparities. This broader view helps healthcare organizations target interventions where unequal outcomes are most evident.
Individual patient information can reveal patterns that extend beyond a single clinical encounter. Population health connects those findings with community and public health strategies, allowing healthcare systems to address shared risks and care needs across defined groups. This connection supports more coordinated responses while retaining the clinical perspective needed to understand patient-level outcomes.
Clinical data are interpreted together with information about health behaviors, environmental conditions, social circumstances, and access to care. Combining these sources provides a fuller explanation of observed outcomes than clinical records alone. It can help identify contributing factors, distinguish potentially preventable disparities, and clarify which patient groups may benefit from focused clinical or community interventions.
A clinical application begins by defining a patient group, examining relevant clinical and contextual information, and identifying outcome patterns or risk factors. Teams can then select preventive, chronic disease, or coordinated interventions, allocate resources, and measure results. Comparing outcomes across groups helps determine whether care quality, equity, and effectiveness are improving.
It is useful when a healthcare system must address needs across defined patient groups rather than isolated cases. Population health findings can support decisions about preventive care, chronic disease management, and coordinated interventions, while outcome measurement shows whether those efforts improve quality and equity. The same framework also helps connect system planning with community-level health priorities.
