In the base projection, the annual number of new infections increases somewhat from 2010 to 2020 largely due to an increase among IDU, required to maintain constant prevalence after a period of declining prevalence among that group.

Plosone

In our simulations, high and constant prevalence of infection in Common Teal (15%) over time led to higher quantities of AIV at infected stopover sites and thus, are likely to increase stopover contamination risk during duck migrations.

Plosone

In our simulations, such a high and constant prevalence rate induced higher quantities of AIV in each halt mesh (i.e. each stopover site see movement model section for details), but did not directly affect AIV spread in space and time (Figure S2).

Plosone

A fairly constant prevalence was observed in Anhui.

Emerging Infectious Diseases

The world-wide constant prevalence of schizophrenia disease suggests an genetic influence.

European Child and Adolescent Psychiatry

Our assumption of constant prevalence of interval-need dependency is conservative for the UK, and indeed more generally [ 34].

A new, empirical approach is applied to test the hypothesis that autism is a constant-prevalence condition that simply has been underdiagnosed in the past.

Environmental Health: A Global Access Science Source

Overall, however, the IDEA data do not support the hypothesis that autism is a constant-prevalence condition, since both the age-resolved snapshots and the constant-age tracking data show a strong and largely consistent upward trend.

In other words, if the hypothesis that autism is a constant-prevalence condition is correct, a snapshot-based prevalence vs. birth year plot should be essentially a flat line with equal prevalence at all ages – albeit a line whose absolute value rises with each new report as diagnosis continues to improve.

Environmental Health: A Global Access Science Source

Given this assumption, it was hypothesized that a snapshot-based prevalence vs. birth year curve would have a flatter slope than a constant-age tracking curve and conceivably would be a completely flat line if autism is truly a constant-prevalence condition.

Environmental Health: A Global Access Science Source

However, if the constant-prevalence hypothesis is correct, even if some of the older children remain undiagnosed and the snapshot-based prevalence vs. birth year plot is not a perfect flat line, it still should have a substantially flatter slope than a constant-age-tracking-based prevalence vs. birth year plot covering the same time interval.

Expert writing Tips

Best practice

When using "constant prevalence", ensure that the context clearly indicates the specific population and timeframe being discussed. This helps avoid ambiguity and ensures accurate interpretation of the data.

Common error

Avoid assuming that a "constant prevalence" indicates a lack of contributing factors. A stable prevalence can still result from a dynamic equilibrium of multiple opposing influences.

Linguistic Context

The phrase "constant prevalence" functions as a noun phrase, where "constant" modifies the noun "prevalence". It describes a state of stability in the proportion of a population affected by a condition, disease, or characteristic. Ludwig AI validates this usage through numerous examples.

Ludwig's WRAP-UP

The phrase "constant prevalence" is a grammatically sound and commonly used term, primarily in scientific and academic contexts, to describe a stable state in the occurrence of a condition within a population. Ludwig AI confirms its accuracy and usability. While it suggests stability, it's crucial to remember that "constant prevalence" can mask underlying dynamics, such as balanced rates of incidence and recovery. Alternatives include "stable prevalence" and "consistent prevalence". When using this phrase, ensure clarity regarding the specific population and timeframe to avoid misinterpretations.

FAQs

How can I use "constant prevalence" in a sentence?

You can use "constant prevalence" to describe a condition or characteristic that remains stable over time in a specific population. For example, "The study observed a "constant prevalence" of the disease despite intervention efforts".

What are some alternatives to "constant prevalence"?

Alternatives to "constant prevalence" include "stable prevalence", "consistent prevalence", or "unchanging prevalence". The choice depends on the specific nuance you want to convey.

What does "constant prevalence" mean in epidemiology?

In epidemiology, "constant prevalence" indicates that the proportion of a population with a particular condition remains relatively stable over a defined period, suggesting that the rates of new cases (incidence) and recovery/mortality are in equilibrium.

Is it accurate to assume that "constant prevalence" means no changes are occurring?

Not necessarily. "Constant prevalence" can mask underlying dynamics. For instance, incidence might be decreasing while survival rates are increasing, resulting in a stable overall prevalence. It's important to consider underlying factors rather than assuming complete stability.
