The impact of obesity on diabetes, hyperlipidemia and hypertension in the United States
ABSTRACT The prevalence of obesity and associated cardiometabolic risk factors such as diabetes, hyperlipidemia and hypertension is increasing significantly for all demographic groups.
The 2000 and 2002 Medical Expenditure Panel Survey (MEPS), a nationally representative survey of the U.S. population, was used to estimate the marginal impact of obesity on health function, perception, and preferences for individuals with diabetes, hyperlipidemia, and hypertension using multivariate regression methods controlling for age, sex, race, ethnicity, education, income, insurance, smoking status, comorbidity, and proxy response. Three different instruments were used: SF-12 physical component scale (PCS-12) and mental component scale (MCS-12); EQ-5D index and visual analogue scale (VAS). Censored least absolute deviation was used for the EQ-5D and VAS (due to censoring) and ordinary least squares (OLS) was used for the PCS-12 and MCS-12.
After controlling for sociodemographic characteristics, diabetes, hyperlipidemia, and hypertension were associated with significantly lower scores compared to normal weight individuals without the condition for all four instruments. Obesity significantly exacerbated this association. Controlling for comorbidity attenuated the negative association of obesity and cardiometabolic risk factors on instrument scores. In addition, scores decreased for increasing weight and number of risk factors.
Obesity significantly exacerbates the deleterious association between diabetes, hyperlipidemia, and hypertension, and health function, health perception, and preference-based scores in the United States.

- "However, only two body weight categories were included in the analyses: normal and obese. The authors did not define the BMI ranges for these categories, and this omission limits the generalizability of these results (Sullivan et al., 2008). "
ABSTRACT: Obesity is a chronic, progressive, multifactorial medical condition. It is known that obesity is associated with cardiovascular disease, metabolic disorders, degenerative joint disorders, and decreased health-related quality of life (HRQoL). In addition, there are socio-economic, gender, age, and racial differences in the population distribution of obesity. The extent to which HRQoL is impaired by obesity independent of associated chronic disease and known demographic risk factors is less well understood by nurses. A secondary analysis of the National Health Measurement Study (NHMS) was conducted to illustrate this relationship. Regression analyses were used to assess the association between body mass index (BMI) and HRQol. BMI was categorized as normal, overweight, obese, and morbidly obese. HRQoL was measured using the EQ-5D and EQ-VAS. After adjusting for chronic health conditions and demographic factors, lower HRQoL was observed as BMI category increased for both the EQ-5D, F = 40.49, 15 df, p < .001, and EQ-VAS, F = 35.5, 15 df, p < .001.Western Journal of Nursing Research 01/2014; 36(8).

Conference Paper: High-speed SiGe HBT track-and-hold[Show abstract] [Hide abstract]
ABSTRACT: A wideband track-and-hold (T/H) circuit is developed based on the IBM 7HP SiGe technology with f<sub>t</sub> ∼ 120 GHz. A switched-emitter-follower design incorporates features necessary to realize multi-GHz bandwidth and an improved design trade among bandwidth, linearity, and hold-mode feedthrough. Simulations incorporating layout parasitics show the core T/H circuit has a bandwidth of ∼ 4 GHz and an extremely wide sampling aperture bandwidth well beyond 10 GHz. The simulations indicate the T/H has roughly 9-10 - bit performance for linearity and feedthrough level at a signal frequency of 4 GHz. Initial experimental results for the track mode response are also presented. The T/H shows promise for high-speed analog-to-digital conversion and subsampling applications.Instrumentation and Measurement Technology Conference, 2003. IMTC '03.
