BACKGROUND little is known about illicit drug use in older people. Prevalences may rise as populations for whom illicit drug use has been more common and acceptable become older. OBJECTIVES to quantify illicit drug use in people aged 50 years and over in England and inner London and to compare this between 50 and 64 and 65+ age groups. METHODS primary analyses used data from the 2007 Adult ...
BACKGROUND While it is assumed that dialysis patients in Japan have a higher prevalence of atrial fibrillation (AF) than the general population, the magnitude of this difference is not known. METHODS Standardized prevalence ratios (SPRs) for AF in dialysis patients (n = 1510) were calculated compared to data from the general population (n = 26 454) living in the same area. RESULTS The preva...
BACKGROUND Breast cancer mortality and incidence rates vary by geographic region in the United States. Previous analytic studies have measured mortality, not incidence, and have used regional prevalences to control for geographic variation in risk factors rather than adjusting for risk factors measured at the level of the individual. We prospectively evaluated regional variation in breast cance...
Numerous studies have shown that anthelminthic treatment can be effective in improving growth rates when given to malnourished children with ascariasis. Recent investigations have also indicated that Ascaris infections can affect mental processing in some school children. Poor socio-economic conditions are among the key factors linked with higher prevalences of ascariasis, as are defaecation pr...
BACKGROUND The prevalence of childhood asthma is increasing but few studies have investigated trends in asthma severity. We investigated trends in asthma diagnosis and symptom morbidity between an eight year time period in a paired prevalence study. METHODS All children in one single school year aged 8-9 years in the city of Sheffield were given a parent respondent questionnaire in 1991 and 1...
OBJECTIVE To estimate HIV prevalence in adults who have not tested for HIV using age-specific mortality rates and to adjust the overall population HIV prevalence to include both tested and untested adults. METHODS An open cohort study was established since 1994 with demographic surveillance system (DSS) and five serological surveys conducted. Deaths from Kisesa DSS were used to estimate morta...
Schoolchildren from 2 areas of Kenya, Kangundo and Kambu, have contrasting prevalences of hepatosplenomegaly, despite having similar prevalences and intensities of Schistosoma mansoni infection. However, in individual children, S. mansoni infection intensity is positively correlated with organomegaly. In a previous study, hepatosplenomegaly was associated with Th1-type anti-schistosome cytokine...
Over the past decade or more, the prevalence of traditional risk factors for atherosclerotic cardiovascular diseases has been increasing in the major populous countries of the developing world, including China and India, with consequent increases in the rates of coronary and cerebrovascular events. Indeed, by 2020, cardiovascular diseases are predicted to be the major causes of morbidity and mo...
Abattoir surveys have demonstrated that oesophagogastric ulceration (OGU) is a common occurrence in pigs throughout the world. Australia is not a exception, with prevalences between 4.7% and 25% having been recorded in previous surveys. The Australian surveys were limited to certain regions and restricted to a small number of farms. (1). Various factors have been linked with risk of OGU develop...
The purpose of this study was to describe differences in cardiovascular risk factor prevalences and clustering patterns among the states and federal territories of Malaysia. Risk factors considered were abdominal obesity, diabetes, hypertension, hypercholesterolemia and smoking. Using data from the third National Health and Morbidity Survey (NMHS III) in 2006, we estimated the states and federa...
