Black patients had a higher prevalence of previous treatment for HF, larger left ventricular volumes, and lower ejection fractions than white patients.
The aim of this study is to determine the prevalence of previous attempted suicide and suicide risk and its connection with the main risk factors.
Nephrolithiasis was rarely detected (0.1 % of the population) compared with the expected 13.9 % prevalence of previous CT studies [13]; this may be explained by a lower sensitivity of MR compared with CT and by the incomplete coverage of the kidneys in the field of view of lumbar spine MRI.
The combined prevalence of previous lung conditions is high across populations and as such they may be important sources of increased lung cancer risk [9],[10], particularly among never smokers.
Paired analysis showed that children with severe and uncomplicated malaria were not significantly different in the prevalence of previous malaria treatment, days of fever, history of cough or vomiting, platelet count and multiplicity of infection (MOI) at recruitment, although parasitemia was higher in severe malaria cases than controls.
Furthermore, no difference between severe malaria cases and non-severe controls was found in the prevalence of previous malaria treatment or the number of days with symptoms of malaria before arrival to hospital, suggesting that severity was not due to a longer progression of the disease among cases.
The prevalence of previous and current medications for RA was similar between groups.
No difference was found in prevalence of previous CS between immigrants and Norwegians.
The prevalence of previous and recent dengue infection and its 95% CI were estimated.
The prevalence of previous CV disease did not differ between the two groups.
The prevalence of previous stroke, ocular disorders, and osteoporosis was highest in institution residents.
