OBJECTIVE: To investigate and monitor the patterns in incidence of childhood type 1 diabetes worldwide. RESEARCH DESIGN AND METHODS: The incidence of type 1 diabetes (per 100,000 per year) from 1990 to 1994 was determined in children < or =14 years of age from 100 centers in 50 countries. A total of 19,164 cases were diagnosed in study populations totaling 75.1 million children. The annual incidence rates were calculated per 100,000 population. RESULTS: The overall age-adjusted incidence of type 1 diabetes varied from 0.1/100,000 per year in China and Venezuela to 36.8/100,000 per year in Sardinia and 36.5/100,000 per year in Finland. This represents a >350-fold variation in the incidence among the 100 populations worldwide. The global pattern of variation in incidence was evaluated by arbitrarily grouping the populations with a very low (<1/100,000 per year), a low (1-4.99/100,000 per year), an intermediate (5-9.99/100,000 per year), a high (10-19.99/100,000 per year), and a very high (> or =20/100,000 per year) incidence. Of the European populations, 18 of 39 had an intermediate incidence, and the remainder had a high or very high incidence. A very high incidence (> or =20/ 100,000 per year) was found in Sardinia, Finland, Sweden, Norway Portugal, the U.K., Canada, and New Zealand. The lowest incidence (<1/100,000 per year) was found in the populations from China and South America. In most populations, the incidence increased with age and was the highest among children 10-14 years of age. CONCLUSIONS: The range of global variation in the incidence of childhood type 1 diabetes is even larger than previously described. The earlier reported polar-equatorial gradient in the incidence does not seem to be as strong as previously assumed, but the variation seems to follow ethnic and racial distribution in the world population.

A new 1 km global IIASA-IFPRI cropland percentage map for the baseline year 2005 has been developed which integrates a number of individual cropland maps at global to regional to national scales. The individual map products include existing global land cover maps such as GlobCover 2005 and MODIS v.5, regional maps such as AFRICOVER and national maps from mapping agencies and other organizations. The different products are ranked at the national level using crowdsourced data from Geo-Wiki to create a map that reflects the likelihood of cropland. Calibration with national and subnational crop statistics was then undertaken to distribute the cropland within each country and subnational unit. The new IIASA-IFPRI cropland product has been validated using very high-resolution satellite imagery via Geo-Wiki and has an overall accuracy of 82.4%. It has also been compared with the EarthStat cropland Global Change Biology (2015Biology ( ) 21, 1980Biology ( -1992Biology ( , doi: 10.1111 product and shows a lower root mean square error on an independent data set collected from Geo-Wiki. The first ever global field size map was produced at the same resolution as the IIASA-IFPRI cropland map based on interpolation of field size data collected via a Geo-Wiki crowdsourcing campaign. A validation exercise of the global field size map revealed satisfactory agreement with control data, particularly given the relatively modest size of the field size data set used to create the map. Both are critical inputs to global agricultural monitoring in the frame of GEOGLAM and will serve the global land modelling and integrated assessment community, in particular for improving land use models that require baseline cropland information.

Computer and internet based questionnaires have become a standard tool in Human-Computer Interaction research and other related fields, such as psychology and sociology. Amazon’s Mechanical Turk (AMT) service is a new method of recruiting participants and conducting certain types of experiments. This study compares whether participants recruited through AMT give different responses than participants recruited through an online forum or recruited directly on a university campus. Moreover, we compare whether a study conducted within AMT results in different responses compared to a study for which participants are recruited through AMT but which is conducted using an external online questionnaire service. The results of this study show that there is a statistical difference between results obtained from participants recruited through AMT compared to the results from the participant recruited on campus or through online forums. We do, however, argue that this difference is so small that it has no practical consequence. There was no significant difference between running the study within AMT compared to running it with an online questionnaire service. There was no significant difference between results obtained directly from within AMT compared to results obtained in the campus and online forum condition. This may suggest that AMT is a viable and economical option for recruiting participants and for conducting studies as setting up and running a study with AMT generally requires less effort and time compared to other frequently used methods. We discuss our findings as well as limitations of using AMT for empirical studies.

The seasonality of the incidence of Type 1 diabetes mellitus in children under 15 years of age is a real phenomenon, as was reported previously and as is now demonstrated by this large standardized study. The seasonality pattern appears to be dependent on the geographical position, at least as far as the northern/southern hemisphere dichotomy is concerned. However, more data are needed on the populations living below the 30th parallel north in order to complete the picture.

OBJECTIVE -To assess the relation between fasting plasma glucose (FPG) or 2-h plasma glucose (2hPG) and mortality from all causes, cardiovascular disease (CVD), and non-CVD and to determine whether the relationship is graded or threshold. RESEARCH DESIGN AND METHODS -Diabetes Epidemiology:Collaborative Analysis Of Diagnostic Criteria in Europe (DECODE) is a collaborative prospective study of 22 cohorts in Europe with baseline glucose measurements for 29,714 subjects aged 30 -89 years who were followed-up for 11 years (329,050 person-years). Hazard ratio (HR) for death was estimated using Cox regression analysis.RESULTS -High glucose concentrations as well as very low glucose levels were associated with increased risk of death. Compared with an FPG of 4.50 -6.09 mmol/l, the multivariateadjusted HR (95% CI) for FPG Ͻ4.50 mmol/l was 1.2 (1.0 -1.4) for all-cause, 1.3 (1.0 -1.8) for CVD, and 1.1 (0.9 -1.4) for non-CVD mortality; the corresponding HRs for diabetes (FPG Ն7.0 mmol/l) were 1.6 (1.4 -1.8), 1.6 (1.3-1.9), and 1.6 (1.4 -1.9), respectively. For a 2hPG of 3.01-4.50 mmol/l, as compared with a 2hPG of 4.51-5.50 mmol/l, the HRs were 1.1 (1.0 -1.2), 1.1 (0.9 -1.3), and 1.1 (1.0 -1.3), respectively; the corresponding HRs for diabetes (2hPG Ն11.1 mmol/l) were 2.0 (1.7-2.3), 1.9 (1.5-2.4), and 2.1 (1.7-2.5), respectively. The HR for previously undetected diabetes defined by 2hPG was not significantly different from that for known diabetes, which was significantly higher than that for undetected diabetes based on FPG. Subjects with a 2hPG of 10.01-11.09 mmol/l had mortality risks similar to those diabetic subjects defined by an FPG Ն7.0 mmol/l. CONCLUSIONS -The relation between mortality and glucose was J shaped rather than showing threshold effect at high glucose levels, except for CVD mortality and 2hPG, where the relation was graded and increasing. Diabetes Care 26:688 -696, 2003D iabetes and impaired glucose tolerance (IGT) are associated with increased mortality, particularly from cardiovascular diseases (CVDs). However, it is still unclear whether the relation between glycemia and mortality is continuous over the entire range of glucose values or whether a threshold for increased mortality exists. This issue has been investigated during the last decades. In 1979, a series of studies from the International Collaborative Group (1) did not consistently detect evidence for a threshold or graded association between asymptomatic hyperglycemia and coronary heart disease. A systematic overview and meta-regression analysis of epidemiological studies found that the progressive relation between glucose levels and CVD risk extends below the diabetic threshold in nondiabetic men (2). This analysis is based on aggregate data, and no adjustment for other risk factors was made. Subsequently, based on data from a 23-year follow-up of the Paris Prospective Study, Balkau et al. (3) reported that the relation between glucose levels and mortality was curvilinear and, in the upper levels of the glucose distributions, the risk of de...

Global gridded crop models (GGCMs) are increasingly used for agro-environmental assessments and estimates of climate change impacts on food production. Recently, the influence of climate data and weather variability on GGCM outcomes has come under detailed scrutiny, unlike the influence of soil data. Here we compare yield variability caused by the soil type selected for GGCM simulations to weather-induced yield variability. Without fertilizer application, soil-type-related yield variability generally outweighs the simulated inter-annual variability in yield due to weather. Increasing applications of fertilizer and irrigation reduce this variability until it is practically negligible. Importantly, estimated climate change effects on yield can be either negative or positive depending on the chosen soil type. Soils thus have the capacity to either buffer or amplify these impacts. Our findings call for improvements in soil data available for crop modelling and more explicit accounting for soil variability in GGCM simulations.
