Despite the common prevalence of lumbar spine and degenerative hip disorders, there are few descriptions of patients with coexisting hip disorders and lumbar spine disorders (LSDs).
Although migraine is a risk factor for WMHs, incidental findings on brain MRI scans are common, prevalence increases with age, and detection is more likely using high resolution MRI sequences than standard resolution sequences [16, 17].
The overall positive rates are very high in Han ethnic areas, and the rate tends to increase with age, suggesting that common transmission routes may determine common prevalence patterns for these two viruses.
The prevalence of common (prevalence >1%) chronic health conditions is provided in Table 1.
Anaemia is also common (prevalence about 50%) in some rheumatological conditions [ 47].
In the community, head lice infestations are very common (prevalence in the general population > 40%).
The one-month prevalence was the most common prevalence period reported and ranged between 27% and 49%.
High levels of DD are common (prevalence, 18 35%; 18-month incidence, 38 48%) and persistent over time, and they are distinct from clinical depression in their linkages with glycemic control and disease management (2– 4).
As the factors we identified in this study are common (prevalence > 10%), the odds ratios (OR) presented in table 4 do not approximate risk ratios (RR).
