OBJECTIVE To determine associations between directly measured insulin sensitivity (SI) and oral glucose tolerance test (OGTT)-derived plasma insulin values, or calculated SI indices, in overweight peripubertal Latino children at risk for type 2 diabetes. RESEARCH DESIGN AND METHODS Thirty overweight Latino children with a family history of type 2 diabetes, aged 8-13 years, Tanner stages 1-2, ...

BACKGROUND Epidemiological studies often require measures of socio-economic position (SEP). The application of principal components analysis (PCA) to data on asset-ownership is one popular approach to household SEP measurement. Proponents suggest that the approach provides a rational method for weighting asset data in a single indicator, captures the most important aspect of SEP for health stud...

Fifteen compounds reported to be inhibitors of gelation or sickling were studied by standard methods. These tests included (1) the determination of the solubility of deoxyhemoglobin S or Csat, (2) evaluation of sickling in whole SS blood at various pO2s, (3) measurement of the oxygen affinity of hemoglobin and blood, and (4) examination of red cell indices and morphology. Among the 4 noncovalen...

The city of Barcarena, a major industrial hub, is high demand for mining industry and accidents that involved environmental contamination by heavy metals such as aluminum, subjecting the population to its harmful efFects. Socio-epidemiological data results toxicological hematological tests 124 individuals were analyzed. statistical analysis adopting significance level p < 0.05. Epidemiologic...

An epidemiological investigation was carried out to determine the relationship between silicosis in hardrock miners in Ontario and cumulative exposure to silica (free crystalline silica--alpha quartz) dust. This second report describes a side-by-side air-sampling program used to derive a konimeter/gravimetric silica conversion curve. A total of 2,360 filter samples and 90,000 konimeter samples ...

UNLABELLED INTRODUCTION Risk of schistosomiasis expansion to semi-arid northeastern Brazil under the influence of the Integration Project of the São Francisco River (IPSFR) was assessed. METHODS Stool examinations of schoolchildren, epidemiological investigation, and survey of the local host snail Biomphalaria straminea were performed in five IPSFR municipalities. RESULTS Six of 4,770 examine...

A problem often encountered in large-scale epidemiological studies is the assessment of a person's relative adiposity from very limited data such as measurements of his height and weight only. There have been several papers in recent years, those of Billewicz, Kemsley and Thomson (1962), Kemsley, Billewicz and Thomson (1962), Khosla and Lowe (1967), Evans and Prior (1969), and Florey (1970), wh...

Several studies have estimated the prevalence of Schizophrenia. Widely varied rates have in part been due to methodological and diagnostic differences. This paper presents the epidemiological indices for Schizophrenia, estimated as a part of a large study of over 1,00,000 urban population for Functional Psychoses. The age corrected prevalence rate is estimated and discussed.A study of socio-dem...

A high prevalence of iron deficiency was found in apparently healthy Asian immigrant children in Harrow. After excluding children with overtly abnormal red cell indices, Asian and European children had identical haemoglobin values, but Asian children had much lower mean cell volume and mean corpuscular haemoglobin values and higher red blood cell values.

OBJECTIVE Many state trauma registries contain work-related information but are underutilized for occupational injury research/surveillance. We assessed three methods of identifying work-related injuries in the Washington State Trauma Registry (WTR). METHODS State-designated trauma facilities report traumatic injuries meeting specific inclusion criteria to the WTR. The WTR reports from 1998 t...
