The Prevalence of Diabetes and Prediabetes Among Elementary School Children in Birjand

Background: Diabetes is associated with increased cardiovascular disease, mortality and morbidity. Objectives: The present study aimed at assessing fasting blood sugar (FBS) in elementary school students in Birjand, 2012. Materials and Methods: This cross-sectional and descriptive study was done on 1530 elementary school students who had been selected through multiple cluster sampling. FBS of these students was tested applying the enzymatic process. The obtained data was analyzed by means of SPSS software (v15) and statistical tests t and X2. Results: In this study, 833 girls and 697 boys were evaluated. Mean FBS of the whole study population was 86.9 ± 8.8 mg/dL; FBS was higher in boys compared to girls. FBS of 1453 (95%) children was < 100 mg/dL, the mean being 85.8 ± 6.8 mg/dL. FBS of 698 (45.6%) students of the above population was 86-99 mg/dl. It was 100-125 mg/dL in 72 (4.7%) individuals. Five (0.3%) students had FBS >126 mg/dL. Mean FBS increased in proportion to age, which was statistically significant. Conclusions: Although the prevalence of diabetes is not considerable; however, based on the relatively high portion of those children with high degree of blood glucose in the range in which the risk of diabetes and prediabetes in the following years rises dramatically, the need for further care of health authorities, an extensive screening activity, and undertaking intervening measures to prevent the epidemic of diabetes and consequently cardiovascular disease is emphasized.

Household language, residential segregation and social mobility: continuity and change in eThekwini, South Africa

This article uses South African census data for 1996, 2001 and 2011 to explore the relationship between language and social mobility in the metropolitan region of eThekwini (including what was previously known as Durban). We focus particular attention on variables selected to shed light on residential segregation and social mobility, such as education level, income, race and in-migration. Data on adults at ward level (using 2011 ward boundaries) in eThekwini is used to develop a comparative spatial context for this analysis. Our main finding is that English appears in eThekwini to be the household language of the social elite as well as the language of upward mobility and empowerment.
