Semiparametric zero-inflated modeling in multi-ethnic study of atherosclerosis (MESA)

Semiparametric Zero-inflated Modeling in Multi-ethnic Study of Atherosclerosis (mesa).

We analyze the Agatston score of coronary artery calcium (CAC) from the Multi-Ethnic Study of Atherosclerosis (MESA) using semi-parametric zero-inflated modeling approach, where the observed CAC scores from this cohort consist of high frequency of zeroes and continuously distributed positive values. Both partially constrained and unconstrained models are considered to investigate the underlying...

Semiparametric Two-Part Models with Proportionality Constraints: Analysis of the Multi-Ethnic Study of Atherosclerosis (MESA)

Optimism and Cardiovascular Health: Multi-Ethnic Study of Atherosclerosis (MESA).

OBJECTIVES We examined the cross-sectional association between optimism and cardiovascular health (CVH). METHODS We used data collected from adults aged 52-84 who participated in the Multi-Ethnic Study of Atherosclerosis (MESA) (n=5,134) during the first follow-up visit (2002-2004). Multinomial logistic regression was used to examine associations of optimism with ideal and intermediate CVH (w...

Statistical Modeling of Agatston Score in Multi-Ethnic Study of Atherosclerosis (MESA)

The MESA (Multi-Ethnic Study of Atherosclerosis) is an ongoing study of the prevalence, risk factors, and progression of subclinical cardiovascular disease in a multi-ethnic cohort. It provides a valuable opportunity to examine the development and progression of CAC (coronary artery calcium), which is an important risk factor for the development of coronary heart disease. In MESA, about half of...

Perceived racial/ethnic discrimination, smoking and alcohol consumption in the Multi-Ethnic Study of Atherosclerosis (MESA).

OBJECTIVE To examine the association of perceived racial/ethnic discrimination with smoking and alcohol consumption in adults participating in the Multi-Ethnic Study of Atherosclerosis. METHODS Data on 6680 black, Chinese, Hispanic and white adults aged 45 to 84 years of age recruited from Illinois, New York, Maryland, North Carolina, Minnesota and California during 2000 and 2002 were used fo...
