Explaining Adult Obesity, Severe Obesity, And Bmi: Five Decades Of Change, Ashley W. Kranjac, Dinko Kranjac
Explaining Adult Obesity, Severe Obesity, And Bmi: Five Decades Of Change, Ashley W. Kranjac, Dinko Kranjac
Sociology Faculty Articles and Research
Obesity rates have increased across all segments of society since the late 1970s, but the reason behind population-level increases in body weight remains unclear. We used the 1971–2020 NHANES data to examine whether the observed trend in obesity prevalence is attributable to changing public health behaviors (i.e., intracohort change) or changing publics (i.e., cohort replacement). We partitioned total change in mean BMI, and rates of obesity and severe obesity, into its IC and CR components using linear and algebraic decomposition methods. We found that the IC mechanism (i.e., broad sectors of individuals changing) plays a dominant role in the overall …
Deconstructing Sex Differences In C-Reactive Protein Trends Over Time, Ashley W. Kranjac, Dinko Kranjac, Olivia Lounsbury
Deconstructing Sex Differences In C-Reactive Protein Trends Over Time, Ashley W. Kranjac, Dinko Kranjac, Olivia Lounsbury
Sociology Faculty Articles and Research
Objectives
Heightened inflammatory state, as measured by circulating C-reactive protein (CRP) levels, can promote inflammation-mediated disease risk. It is important to account for population fluctuation and sex variation in serum CRP concentrations on overall time trends.
Methods
Using the National Health and Nutrition Examination Survey data, we specify linear and algebraic decomposition models separately by sex to identify the drivers of the changing trends in the distribution of CRP values in the population.
Results
We found a nonsignificant overall increase in CRP, but a significant decrease among women and increase among men, over a 10-year period. We then used linear …
Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac
Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac
Sociology Faculty Articles and Research
As of 1 November 2020, estimated case-fatality rates associated with coronavirus disease 2019 are not uniformly patterned across the world and differ substantially in magnitude. Given the global spatial heterogeneity in case-fatality rates, we applied the Blinder-Oaxaca regression decomposition technique to identify how putative sociodemographic, structural, and environmental sources influence variation in case-fatality rates. We show that compositional and associational differences in country-level risk factors explain a substantial proportion of the coronavirus disease 2019-related case-fatality rate gap across nations. Asian countries fair better vis-à-vis case-fatality rate differences mainly due to variation in returns to sociodemographic, structural, and environmental sources among …
The Effects Of Zoledronate And Sleep Deprivation On The Distal Femur Trabecular Thickness Of Ovariectomized Rats: Application Of Different Statistical Methods, Erin Nolte
Student Scholar Symposium Abstracts and Posters
Osteoporosis is a disease that causes the degradation of bone, leading to an increased risk of fracture. 1 in 3 women over the age of 50 will be affected by Osteoporosis. This study aims to understand how bone is affected by sleep deprivation in estrogen-deficient rats, and how Zoledronate might negate the inimical effects of sleep deprivation on bone. As bone mineral density (BMD) is a crude evaluation of the architectural changes seen in Osteoporosis, trabecular thickness may serve as a better single evaluation of bone health. 31 Wistar female rats were ovariectomized and separated into 4 random groups. The …
School‐Level Body Mass Index Shapes Children's Weight Trajectories, Ashley W. Kranjac
School‐Level Body Mass Index Shapes Children's Weight Trajectories, Ashley W. Kranjac
Sociology Faculty Articles and Research
BACKGROUND
Embedded within children's weight trajectories are complex environmental contexts that influence obesity risk. As such, the normative environment of body mass index (BMI) within schools may influence children's weight trajectories as they age from kindergarten to fifth grade.
METHODS
I use 5 waves of the ECLS‐K—Kindergarten Class 1998‐1999 data and a series of multilevel growth models to examine whether attending schools with higher overall BMI influences children's weight status over time.
RESULTS
Results show that, net of child, family, and school sociodemographic characteristics, children who attend schools with higher rates of obesity have increased weight compared to children who …
