Pediatric Obesity In The United States: Age–Period–Cohort Analysis, Ashley W. Kranjac, Dinko Kranjac, Roxanne I. Aguilera

Sociology Faculty Articles and Research

The rates of obesity among American children aged 2–5 years has reached a historic high. It is crucial to identify the putative sources of population-level increases in obesity prevalence among preschool-aged children because early childhood is a critical window for obesity prevention and thus reduction of future incidence. We used the National Health and Nutrition Examination Survey data and hierarchical age–period–cohort analysis to examine lifecycle (i.e., age), historical (i.e., period), and generational (i.e., cohort) distribution of age- and sex-specific body mass index z-scores (zBMI) among 2–5-year-olds in the U.S. from 1999 to 2018. Our current findings indicate that period effects, …

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 …

Obesity Heterogeneity By Neighborhood Context In A Largely Latinx Sample, Ashley W. Kranjac, Dinko Kranjac, Zeev N. Kain, Louis Ehwerhemuepha, Brooke N. Jenkins

Sociology Faculty Articles and Research

Neighborhood socioeconomic context where Latinx children live may influence body weight status. Los Angeles County and Orange County of Southern California both are on the list of the top ten counties with the largest Latinx population in the USA. This heterogeneity allowed us to estimate differential impacts of neighborhood environment on children’s body mass index z-scores by race/ethnicity using novel methods and a rich data source. We geocoded pediatric electronic medical record data from a predominantly Latinx sample and characterized neighborhoods into unique residential contexts using latent profile modeling techniques. We estimated multilevel linear regression models that adjust for …

Spatial Disparities: The Role Of Nativity In Neighborhood Exposure To Alcohol And Tobacco Retailers, Georgiana Bostean, Luis A. Sánchez, Jason A. Douglas

Sociology Faculty Articles and Research

Studies of retail environment, one of the social determinants of health, document racial/ethnic disparities in exposure to alcohol and tobacco (A and T) retailers, but have largely overlooked nativity. We examined associations between A and T retailer density and rates of foreign-born Latinx and foreign-born Asian residents in California census tracts (N = 7888), using spatial regressions and controlling for population and ecological confounders (e.g., population density, zoning, residential instability, urbanicity). Socio-demographic data came from the American Community Survey (2012–2016); census tract density of A and T retailers came from geocoded addresses from state license data for off-sale alcohol distributors …

County-Level Factors That Influenced The Trajectory Of Covid-19 Incidence In The New York City Area, Ashley Wendell Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

More than a century of research has shown that sociodemographic conditions affect infectious disease transmission. In the late spring and early summer of 2020, reports of the effects of sociodemographic variables on the spread of COVID- 19 were used in the media with minimal scientific proof attached. With new cases of COVID-19 surging in the United States at that time, it became essential to better understand how the spread of COVID-19 was varying across all segments of the population. We used hierarchical exponential growth curve modeling techniques to examine whether community socioeconomic characteristics uniquely influence the incidence of reported COVID-19 …

Child Obesity Moderates The Association Between Poverty And Academic Achievement, Ashley W. Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

Childhood overweight and obesity are major public health problems in the United States. Children who experience poverty are 1.5 times more likely to suffer with overweight and 1.6 times more likely to have obesity. The extent to which overweight or obesity exacerbates the negative influence of socioeconomic inequality on child academic outcomes has not yet been examined. We estimated the effect of poverty on math and reading achievement trajectories using the Early Childhood Longitudinal Study (ECLS) Kindergarten class of 1998−1999 survey data and multilevel growth curve modeling techniques. Our findings indicate that the impact of obesity status is more pronounced …

Surgical Patients’ Hospital Experience Scores: Neighborhood Context Conceptual Framework, Ashley Wendell Kranjac, Dinko Kranjac, Michelle A. Fortier, Pat Patton, Brad Giafaglione, Zeev N. Kain

Sociology Faculty Articles and Research

Objective:

Through geocoding the physical residential address included in the electronic medical record to the census tract level, we present a novel model for concomitant examination of individual patient-related and residential context-related factors that are associated with patient-reported experience scores.

Summary Background Data:

When assessing patient experience in the surgical setting, researchers need to examine the potential influence of neighborhood-level characteristics on patient experience-of-care ratings.

Methods:

We geocoded the residential address included in the electronic medical record (EMR) from a tertiary care facility to the census tract level of Orange County, CA. We then linked each individual record to the …

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 …

Decomposing Trends In Child Obesity, Ashley Wendell Kranjac, Robert L. Wagmiller

Sociology Faculty Articles and Research

We unravel the absolute level and relative prominence of two demographic processes that are relevant for childhood obesity, and that will ultimately determine the long-term course and pace of change in child obesity rates. We leverage data from the National Health and Nutrition Examination Survey to decompose change in child obesity from 1971 to 2012. We partition change into that attributable to (1) healthier, more nutritionally and economically advantaged cohorts in the population being replaced by cohorts of children who are less advantaged (between-cohort change), and (2) the health habits, nutrition, and social and economic circumstances of all cohorts of …

Child Obesity And The Interaction Of Family And Neighborhood Socioeconomic Context, Ashley W. Kranjac, Justin T. Denney, Rachel T. Kimbro, Brady S. Moffett, Keila N. Lopez

Sociology Faculty Articles and Research

The literature on neighborhoods and child obesity links contextual conditions to risk, assuming that if place matters, it matters in a similar way for everyone in those places. We explore the extent to which distinctive neighborhood types give rise to social patterning that produces variation in the odds of child obesity. We leverage geocoded electronic medical records for a diverse sample of over 135,000 children aged 2 to 12 and latent profile modeling to characterize places into distinctive neighborhood contexts. Multilevel models with cross-level interactions between neighborhood type and family socioeconomic standing (SES) reveal that children with different SES, but …

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 …

Smoking Trends Among U.S. Latinos, 1998–2013: The Impact Of Immigrant Arrival Cohort, Georgiana Bostean, Annie Ro, Nancy L. Fleischer

Sociology Faculty Articles and Research

Few studies examine nativity disparities in smoking in the U.S., thus a major gap remains in understanding whether immigrant Latinos’ smoking prevalence is stable, converging, or diverging, compared with U.S.-born Latinos. This study aimed to disentangle the roles of period changes, duration of U.S. residence, and immigrant arrival cohort in explaining the gap in smoking prevalence between foreign-born and U.S.-born Latinos. Using repeated cross-sectional data spanning 1998–2013 (U.S. National Health Interview Survey), regressions predicted current smoking among foreign-born and U.S.-born Latino men and women (n = 12,492). We contrasted findings from conventional regression analyses that simply include period and duration …

Comprehensive Neighborhood Portraits And Child Asthma Disparities Introduction, Ashley W. Kranjac, Rachel T. Kimbro, Justin T. Denney, Kristin M. Osiecki, Brady S. Moffett, Keila N. Lopez

Sociology Faculty Articles and Research

Objectives Previous research has established links between child, family, and neighborhood disadvantages and child asthma. We add to this literature by first characterizing neighborhoods in Houston, TX by demographic, economic, and air quality characteristics to establish differences in pediatric asthma diagnoses across neighborhoods. Second, we identify the relative risk of social, economic, and environmental risk factors for child asthma diagnoses. Methods We geocoded and linked electronic pediatric medical records to neighborhood-level social and economic indicators. Using latent profile modeling techniques, we identified Advantaged, Middle-class, and Disadvantaged neighborhoods. We then used a modified version of the Blinder-Oaxaca regression decomposition method to …

E-Cigarette Specialty Retailers: Data To Assess The Association Between Retail Environment And Student E-Cigarette Use, Georgiana Bostean, Catherine M. Crespi, Patsornkarn Vorapharuek, William J. Mccarthy

Sociology Faculty Articles and Research

The retail environment is a major social determinant of health, yet little is known about the e-cigarette specialty retailer environment. The e-cigarette specialty retail environment may be associated with e-cigarette use by middle and high school students, an issue that was addressed in a recent article entitled, “E-cigarette use among students and e-cigarette specialty retailer presence near schools,” by Bostean and colleagues (G. Bostean, C.M. Crespi, P. Vorapharuek, W.J. McCarthy, 2016). We present data relating to e-cigarette specialty retailers in Orange County, California. We describe the data collection method (including the search methodology to identify e-cigarette specialty retailers), present descriptive …

Depression And Body Mass Index, Differences By Education: Evidence From A Population-Based Study Of Adult Women In The U.S. Buffalo-Niagara Region, Ashley Wendell Kranjac, Jing Nie, Maurizio Trevisan, Jo L. Freudenheim

Sociology Faculty Articles and Research

The relationship between obesity and depression is well described. However, the evidence linking depression and body mass index (BMI) across the broad range of body size is less consistent. We examined the association between depressive symptoms and BMI in a sample of adult women in the Buffalo-Niagara region between 1997 and 2001. Using logistic regression, we investigated whether increased weight status beyond normal-weight was associated with a higher prevalence of depressive symptoms, and if educational attainment modified the association between obesity and depression. There was a trend for increased weight status to be associated with higher depressive symptoms (obese II/III, …

Who Cares? Caregiver Well-Being In Europe, Leah Ruppanner, Georgiana Bostean

Sociology Faculty Articles and Research

This paper analyzes a multi-national sample comparing self-reported well-being of those who provide dependent care to that of non-caregivers. We pair individual-level data from the 2004 European Social Survey (ESS) for respondents in 22 nations (n=41,000+) with country-level measures of attitudinal support for co-residential familial caregiving (2007 Eurobarometer), old age and family public transfers (OECD Social Expenditures Database, 2014) and economic development (GDP). Using multi-level modeling, we examine the association between country-level co-residential familial attitudes and public spending and individual-level caregiver well-being, comparing effects by gender. We find that: (1) caregiving is differentially associated with well-being for men and women; …
