TITLE: Ethnic differences in metabolic achievement between Māori, Pacific, and European New Zealanders with type 2 diabetes

Aims To compare variations in metabolic target achievement by ethnicity (Europeans, Māori and Pasifika) among patients with type 2 diabetes (T2DM) in Auckland, New Zealand (NZ) between 1994-2013. Methods 32,237 patients were enrolled. Adjusted marginal difference (European as reference) of systolic blood pressure (SBP), body mass index (BMI), HbA1c and total cholesterol, alongside the proportion achieving metabolic targets were estimated using multivariable mixed effect models at baseline, 1-, 2-, 3-, 4-, and 5-years, adjusted for covariates. Results Compared with Europeans, Māori and Pasifika had continuously, significantly higher HbA1c (by 0.3% (+3.5mmol/mol) and 0.6% (+6.8 mmol/mol) respectively and BMI (+1.5 and +0.3 kg/m2 respectively) but lower SBP (-1.8 and -3.4 mmHg respectively) and TG (-0.03 and -0.34 mmol/L respectively), and insignificantly TC (+0.004 and +0.01 respectively), by 5-year of follow-up. While 49% Europeans were within target HbA1c, this was achieved by only 30% Māori and 27% Pasifika. Conversely, 41% Europeans, 46% Māori and 59% Pasifika achieved the SBP target (all P<0.0001). Conclusions Managing hyperglycemia appears to be more challenging than treating hypertension and dyslipidemia in these ethnic groups. New anti-hyperglycemia treatments, addressing health literacy, socioeconomic and any cultural barriers to management and self-management are urgently needed to reduce these disparities

Winds of Change: A Century of Agroclimate Research

Climate has been of primary concern from the beginning of agricultural research. Early in the 20th century, climatology and agronomy evolved separately, focusing primarily on production agriculture and crop adaptation. Concepts developed include thermal units and water use efficiency. The integrated discipline of agroclimatology developed in the mid-20th century. As theoretical understanding evolved, numerous papers related to agroclimatology were named Citation Classics. Spectral properties of plants and soils were identified that underpin today’s remote sensing technologies. Commercialization of instrumentation enhanced our ability to efficiently collect data using standardized methods. Private and public-sector partnerships advanced research capacity. Later in the 20th century, research focus shifted toward integrating knowledge into crop growth and agronomic models. Remote sensing provided capacity to gain theoretical and practical understanding of regional scale processes. In the early 21st century, recognition of earth as a system along with inter-related human systems is driving research and political agendas. There is a pressing need to change our data-rich to an information-rich environment. The emerging cyberinformatics field along with natural resource and agricultural system models allow us to apply climate information to assessments and decision support related to water supply, production, environmental management, and other issues. Solutions to today’s problems require interdisciplinary and multi-sectoral teams. While needs have never been greater, fewer universities maintain critical mass required to off er advance degrees in agroclimatology. It will be increasingly important that agrclimatology attract top students and provide training and practical experience in conducting integrated systems research, communications, and team skills
