And, in a virtuous cycle, the decreased prevalence of crime fuels a decrease in the prevalence of crime.
Our analyses demonstrated that from 1994 to 2003, in 44 of 50 states, the increase in autism was completely offset by a decrease in the prevalence of children considered "cognitively disabled" or "learning disabled".
This decrease in the prevalence of offspring with part or full domestic ancestry is consistent with the reductions in relative hybrid survivorship observed in experimental studies13,21,37 and expected selection against these individuals in the wild.
The decrease in the prevalence of hepatitis A in Spain may modify the characteristics of this infection because of the rise in the susceptible adult population.
The widespread use of fluconazole has contributed to a relative decrease in the prevalence of C. albicans, while species inherently less susceptible, such as Candida glabrata and Candida krusei, appear to be isolated with greater frequency.
However, unlike previous studies, we observed a decrease in the prevalence of CH with age.
We observed a decrease in the prevalence of TTH with age, which is also in agreement with preexisting data.
If respiratory signs and symptoms predict future lung function loss, then improvements in population lung function over the past decade should have been paralleled by a decrease in the prevalence of these variables in the same population.
Using the Gottschalk-Hansen classification approach also found a decrease in the prevalence of graduate jobs and a rise in overeducation during the 2000s.
However, men in the 80th percentile of decision latitude had more than a 50% decrease in the prevalence of hypertension compared with men in the 20th percentile (odds ratio =.46, 95% confidence interval = 22, 96).
In other words, the sharp decline in the age-crime curve that occurs in early adulthood reflects both a decrease in the prevalence of offending and a decrease in the frequency of offending (Piquero et al. 2003).
