Study protocol for a multimethod investigation of the development of social and nonsocial reward responsivity and depression in autistic adolescents
This systematic study of reward responsivity and depression in autistic adolescents is likely to advance our collective understanding of depression in this population by informing risk stratification models and identifying potential intervention targets. Findings may also establish the reliability of several clinical and neural measures of reward responsivity in this population that can eventually be used to measure treatment outcome and identify…
Profiles of Structural Violence in Hispanic/Latino Immigrant and Non-Immigrant Parents
This study provides critical insights into the pervasive structural violence and compounded stress experienced by Hispanic/Latino caregivers, a population disproportionately impacted by systemic inequities that can adversely affect overall well-being. We analyzed data from the Hispanic Community Health Study/Study of Latinos Youth (n = 458) to identify structural violence exposure patterns among Hispanic/Latino caregivers/parents and examine how …
Standardizing and Improving Primary Care-Based Electronic Developmental Screening for Young Children in Federally Qualified Health Center Clinics
Implementation of electronic screening tools improved universal developmental screening in a FQHC. To decrease barriers in under-resourced communities, the use of electronic tools may decrease the rate of screening error seen with paper screening and have the potential to better identify children at risk for developmental delay
Exploratory study evaluating the relationships between perinatal adversity, oxidative stress, and infant neurodevelopment across the first year of life
Early childhood adversity increases risk for negative lifelong impacts on health and wellbeing. Identifying the risk factors and the associated biological adaptations early in life is critical to develop scalable early screening tools and interventions. Currently, there are limited, reliable early childhood adversity measures that can be deployed prospectively, at scale, to assess risk in pediatric settings. The goal of this two-site longitudinal…

Accelerometer-Measured Latent Physical Activity Profiles and Neurocognition Among Middle-Aged and Older Hispanic/Latino Adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)
We found no consistent evidence to link accelerometry-measured MVPA profiles to neurocognitive function. Research to better characterize the role of high occupational MVPA in relation to neurocognition among Hispanic/Latino adults are needed
Immigration Status and Disparities in the Treatment of Cardiovascular Disease Risk Factors in the Hispanic Community Health Study/Study of Latinos (Visit 2, 2014–2017)
Objectives. To estimate treatment rates of high cholesterol, hypertension, and diabetes among Hispanic/Latino immigrants by immigration status (i.e., naturalized citizens, documented immigrants, or undocumented immigrants). Methods. We performed a cross-sectional analyses of the Hispanic Community Health Study/Study of Latinos (visit 2, 2014–2017). We restricted our analysis to Hispanic/Latino immigrants with high cholesterol (n = 3974), hyperten…
Perceived discrimination and physical health-related quality of life
Implications of standardization of serum 25-hydroxyvitamin D data for the evaluation of vitamin D status in Germany, including a temporal analysis
The use of standardization of 25(OH)D levels has a substantial impact on estimates of the vitamin D status in Germany. Since clinical diagnostic, therapeutic and public health decision-making require valid and comparable data, standardization and calibration of commercial, clinical and research laboratory assays for 25(OH)D measurement should become common practice. Until then, researchers, health practitioners and policy makers should be aware o…
Cardiovascular risk status of Afro-origin populations across the spectrum of economic development
These data provide a comprehensive estimate of cardiovascular risk across a range of countries at differing stages of social and economic development and demonstrate the heterogeneity in the character and degree of emerging cardiovascular risk. Severe hypercholesterolemia, as characteristic in the US and much of Western Europe at the onset of the coronary epidemic, is unlikely to be a feature of the cardiovascular risk profile in these countries …
The social patterning of risk factors for noncommunicable diseases in five countries
In conclusion, the distribution of NCD-RFs was socially patterned in these populations at different stages of the epidemiological transition, but associations between SES and NCD-RFs differed substantially according to risk factor, population, sex, and SES indicator. These findings emphasize the need to assess and integrate the social patterning of NCD-RFs in NCD prevention and control programs in LMICs
Association of car ownership and physical activity across the spectrum of human development
PA levels are similar across all study sites except Jamaica, despite very different levels of socioeconomic development. Not owning a car in the US is associated with especially high levels of MVPA. As car ownership becomes prevalent in the developing world, strategies to promote alternative forms of active transit may become important
A comparison of indices of glucose metabolism in five black populations
Obesity, metabolic risk, and other potential determinants vary significantly between populations at differing stages of the epidemiologic transition, requiring tailored public health policies to address local population characteristics
Leveraging social influence to address overweight and obesity using agent-based models
A mixed ecologic-cohort comparison of physical activity & weight among young adults from five populations of African origin
These analyses suggest that persons with greater adiposity tend to engage in less PA, although the associations are weak and the direction of causality cannot be inferred because measurements are cross-sectional. Longitudinal data will be required to elucidate direction of association
Comparisons of intensity-duration patterns of physical activity in the US, Jamaica and 3 African countries
While there is some association for PA with obesity, this relationship is inconsistent across the epidemiologic transition and suggests that PA policy recommendations should be tailored for each environment
Hydroxyvitamin D levels in African American and Nigerian women
OBJECTIVES: African Americans (AA) have substantially lower levels of circulating 25-hydroxyvitamin D (25(OH)D) than whites. We compared population-based samples of 25(OH)D in women of African descent from Nigeria and metropolitan Chicago. METHODS: One hundred women of Yoruba ethnicity from southwest Nigeria and 94 African American women from metropolitan Chicago were recruited and compared using a standardized survey protocol and the same labora…
Protocol for the modeling the epidemiologic transition study
METS will provide insight on the relative contribution of physical activity and diet to excess weight, age-related weight gain and incident glucose impairment in five populations' samples of young adults at different stages of economic development. These data should be useful for the development of empirically-based public health policy aimed at the prevention of obesity and associated chronic diseases
Assessing Physical Activity and its Relationship to Cardiovascular Risk Factors
The magnitude of the gap between self-report and accelerometry activity must be a result of either a vast social acceptability bias in reporting or inaccurate measurement with accelerometry. Therefore, due to the low validity of self reported PA data for epidemiologic research, it is pertinent to encourage the use of valid, objective methods to assess PA
Rationale and methods of the cardiometabolic valencian study (escarval-risk) for validation of risk scales in mediterranean patients with hypertension, diabetes or dyslipidemia
The Escarval-Risk study will provide information to validate different cardiovascular risk scales in patients with hypertension, diabetes or dyslipidemia from a low risk Mediterranean Region, the Valencia Community
Rapid increases in obesity in Jamaica, compared to Nigeria and the United States
Weight change in sample cohorts from a middle-income country was greater than in cohorts from either of the low- or high-income countries. The steep trajectory of weight gain in Jamaica, relative to Nigeria and the US, is most likely attributable to the accelerating effects of the cultural and behavioral shifts which have come to bear on transitional societies
Cardiovascular disease surveillance in Mexicans and Mexican Americans
Throughout its history, the United States has consistently received large numbers of immigrants from around the world. Most early immigration originated in Europe, but the more recent influx has been dominated by people from Asia and Latin America (1). In the year 2002, the number of people of Hispanic origin in the United States reached over 37 million (2). The vast majority of this U.S. subpopulation are of Mexican descent (66.9%), with smaller…
Effect of Increased Copayments on Pharmacy Use in the Department of Veterans Affairs
OBJECTIVES: In February 2002, the Department of Veterans Affairs (VA) raised medication copayments from $2 to $7 per 30-day supply of medication for certain veteran groups. We examined the impact of the copayment increase on medication acquisition from VA. METHODS: This was a retrospective cohort study using data from national VA databases from February 2001 through February 2003. We took a random sample of over 5% of male VA users in 2001. Of 14…
Health Insurance Coverage and the Risk of Decline in Overall Health and Death Among the Near Elderly, 1992–2002
BACKGROUND: Although individuals' health insurance coverage changes frequently, previous analyses have not accounted for changes in insurance coverage over time. OBJECTIVE: We sought to determine the independent association between lack of insurance and the risk of a decline in self-reported overall health and death from 1992 to 2002, accounting for changes in self-reported overall health and insurance coverage. METHODS: We analyzed data from the…
Racial Differences in Survival Among Men With Prostate Cancer and Comorbidity at Time of Diagnosis
Objectives. This study evaluated the effect of comorbidity at diagnosis on racial differences in survival among men with prostate cancer. Methods. Clinical and demographic data were abstracted from records of 864 patients diagnosed at 4 Chicago area hospitals between 1986 and 1990. Comorbidity was scored on the basis of clinical information in the Charlson index. Cause-specific relative mortality adjusted for age, stage, differentiation, and trea…
Mortality patterns among adult Hispanics
OBJECTIVES: The purpose of this study was to assess the mortality pattern of the adult Hispanic population in the United States. METHODS: This was a cohort study using data from the National Health Interview Survey from 1986 through 1990. Deaths were ascertained by matching the National Death Index through 1991. RESULTS: This representative national sample included 297,640 non-Hispanic Whites, 53,552 Blacks, and 27,239 Hispanics, all aged 18 year…
