OBJECTIVE— To assess the magnitude of association between National Cholesterol Education Program’s Third Adult Treatment Panel Report (ATP III) definition metabolic syndrome and cardiovascular disease (CVD). RESEARCH DESIGN AND METHODS— Cox regression was used to estimate relative risk incident coronary heart (CHD) stroke among 12,089 black white middle-aged individuals in Atherosclerosis Risk Communities (ARIC) study. RESULTS— The present ∼23% without diabetes or prevalent CVD at baseline....
To assess the prospective association between metabolic syndrome (MetS) and cardiovascular disease (CVD) in older people to evaluate effect of lowering threshold for impaired fasting glucose (IFG) on prevalence IFG MetS risk CVD.Prospective cohort study.Four field centers U.S. communities.Three thousand five hundred eighty-five subjects Cardiovascular Health Study free diabetes mellitus CVD at baseline (mean age 72, 62% female, 14% black).Baseline measures components adjudicated incident...
One key constraint to further understanding plant root development is the inability observe growth in situ due opaque nature of soil. Of present non-destructive techniques, computed tomography (CT) best able capture complexities edaphic environment. This study compared accuracy and impact X-ray CT measurement systems with standard technology (soil core washing WinRhizo analysis) context treatments that differed vertical placement phosphorus fertilizers within soil profile. Although lengths...
Among patients with heart failure (HF), early readmission or death and repeat hospitalizations may be indicators of poor disease management more severe disease.We assessed the association neighborhood median household income (nINC) Medicaid status rehospitalization in Atherosclerosis Risk Communities cohort study (1987 to 2004) after an incident HF hospitalization context individual socioeconomic evaluated relationship for modification by demographic comorbidity factors. We used generalized...
Reduced low forced expiratory volume in 1 second (FEV1) is reportedly associated with an increased risk of atrial fibrillation (AF). Extant reports do not provide separate estimates for never smokers or blacks, who incongruously have lower AF incidence than whites.We examined 15 004 middle-aged blacks and whites enrolled the Atherosclerosis Risk Communities (ARIC) cohort study. Standardized spirometry data were collected at baseline examination. Incident was identified from first among...
A leaf-feeding technique for in situ 15N-labelling of intact soil–pasture plant systems was assessed, using subterranean clover (Trifolium subterraneum L.) and serradella (Ornithopus compressus grown under glasshouse conditions. Total recoveries fed 15N were 87–100% following plants at flowering but lower (74–84%) the feed vegetative stage. Below-ground recovery ranged from 7 to 26%, with partitioning a greater proportion labelled N below ground than clover. Additionally, both species stage...
Background— The association of central adiposity with incident heart failure (HF) has yet to be studied in a large population-based study. Methods and Results— Atherosclerosis Risk Communities study is an ongoing biracial cohort those aged 45 64 years from 4 US communities 16 years’ median follow-up for incident, hospitalized, or fatal HF. Waist-hip ratio, waist circumference, body mass index (BMI) were measured at baseline (1987–1989). After exclusions, the sample size was 14 641. BMI...
The effects of various management practices on soil phosphorus (P) dynamics were investigated in a field experiment New South Wales, Australia, during 24 years different crop rotation, stubble management, and tillage treatments. Topsoil samples collected at the beginning trial after 6, 12, 18, analysed for resin-extractable P, inorganic organic total P. According to calculated P input–output budget, 9–14 20 kg P/ha added as superphosphate annually remained system, depending treatment....
