Contribution of social and lifestyle factors to cognitive status and 5-year change among middle-aged and older Americans
Cognitive decline is a global health concern that leads to significant impairment in daily functioning and quality of life. Limited large-scale cohort studies have concurrently examined the effects of lifestyle and social factors on cognitive status and the potential gender and age cohort differences in middle-aged and older adults. This longitudinal study examined the temporal associations between lifestyle and social factors and cognitive statu…

Does the Association between Changes in Health Behaviors and Weight Gain Differ by Race and Ethnicity During the (Covid)-19 Pandemic? Findings from a Population-based Study
Objectives: We examined racial and ethnic differences in the association between changes in lifestyle behaviors and weight gain during COVID-19. Methods: We obtained data from a 2020 national survey involving 2,709 adult Americans. The outcome of interest was self-reported weight change status; behavioral measures included changes in exercise time, screen time, fast food meals consumed, and alcohol and tobacco use. We performed weighted multivari…
A review of bidimensional acculturation and STI/HIV-related sexual risk behaviours among Hispanic youth
A growing body of research suggests that acculturation may play a role in the disproportionate likelihood of sexual risk behaviour and STI/HIV infection among Hispanic youth in the USA. We systematically reviewed the relationship between acculturation and STI/HIV-related sexual risk behaviour among Hispanic youth aged 13-24 by reviewing studies that have used a bidimensional acculturation approach. Electronic databases were searched with the sear…

Racial-ethnic disparities in psychological distress during the Covid-19 pandemic in the United States: The Role of Experienced Discrimination and Perceived Racial Bias
Experience of Racial Discrimination was Associated with Psychological Distress and Worsening Sex Life Among Adult Americans During Covid-19
The recent escalation of racism in the U.S. during the COVID-19 pandemic points to the importance of examining the association between experienced racism and sexual health. Based on data from a nationally representative survey conducted in the U.S. in October 2020 (n = 1,915), Chi-square tests and multivariable logistic regressions were estimated to examine the association between experience of racism and changes in sex life during the pandemic. …
Americans’ Trust in Covid-19 Information from Governmental Sources in the Trump Era: Individuals’ Adoption of Preventive Measures, and Health Implications
This study analyzes differences among Americans in their trust in COVID-19 information from governmental sources and how trust is associated with personal adoption of preventative measures under the Trump administration. Based on our analysis of data from a nationally representative survey conducted in October 2020 (effective sample size after weighting = 2615), we find that Americans in general have more trust in COVID-19 information from state/…
Generation 1.5: Years in the United States and Other Factors Affecting Smoking Behaviors Among Asian Americans
While Asian men who came to the United States before 12 were less at risk for cigarette smoking than those who immigrated in adulthood, the pattern was the opposite among Asian women. Those who spent their childhood in the United States were more likely to smoke than those who came to the United States in adulthood. These patterns might result from the cultural differences between US and Asian countries, and bear policy relevance for the tobacco …
Knowledge and Attitudes of Cypriots on Melanoma Prevention: Is there a Public Health Concern

Barriers to Pediatric Mental Healthcare Access: Qualitative Insights from Caregivers
The Centers for Disease Control and Prevention approximates that 1 in 5 children experience a mental or behavioral health disorder. Pediatric mental healthcare service access cannot be improved without strong coordination between educational settings, social service providers for children, and adequate policy support. Addressing this critical child development issue is dependent on us understanding the barriers to mental healthcare access faced b…
Racism Experience Among American Adults During Covid-19: A Mixed-Methods Study
Racism experience is not only correlated with factors at individual level, it is also associated with contextual factors such as political climate, neighborhood diversity, and population age structure. Future efforts in supporting victims of racism might be more cost-effective by focusing on the identified vulnerable groups and related contextual factors

Changes in Leisure Time Physical Activity Preferences and Hypertension Risk
Objectives: In this study, we examined the association between changes in leisure time physical activity (LTPA) preference (the extent to which participants liked or disliked certain types of physical activity) and the incidence of hypertension; we also assessed whether the association differed between urban and rural China. Methods: Based on longitudinal data from 2687 Chinese adults between 2004 and 2011, we performed multivariate logistic regr…
Association between leisure time physical activity preference and behavior: Evidence from the China Health & Nutrition Survey, 2004–2011

Obesity and Income Inequality in OECD Countries
Countries of the Organization for Economic Cooperation and Development (OECD) exhibit substantial increases in both income inequality and obesity prevalence since the 1970s. Income inequality may affect obesity through increased psychosocial distress, concentrated poverty, erosion of social cohesion, and inadequate policy interventions. Substantial variations appear in estimated obesity prevalence across OECD countries in 2010. Particularly impor…

Risk Exposure in Early Life and Mortality at Older Ages: Evidence from Union Army Veterans
This study examines the relation between risk exposures in early life and hazard of mortality among 11,978 Union Army veterans aged 50 and over in 1900. Veterans' risk exposures prior to enlistment-as approximated by birth season, country of birth, residential region, city size, and height at enlistment-significantly influenced their chance of survival after 1900. These effects are robust irrespective of whether socioeconomic well-being in 1900 h…

Assessing Cultural Assimilation of Mexican Americans: How Rapidly Do Their Gender-Role Attitudes Converge to the U.S. Mainstream
Objective. This study assesses the pace of cultural assimilation of Mexican Americans by comparing changes in their gender-role attitudes over generations to the European-origin U.S. mainstream. Methods. Using cumulative data from the 1972–2004 General Social Survey, we examine the rate at which progressive generations of Mexican Americans approach the mainstream gender-role attitudes. We also employ a set of logistic regressions to assess the di…

Is Self-Rated Health Comparable Between Non-Hispanic Whites and Hispanics? Evidence From the Health and Retirement Study
Health disparities between whites and Hispanics aged between 51 and 61 will be overestimated if the assessment has been solely based on differences in SRH between the two groups. Findings from this study call for caution in relying on SRH to quantify and explain health disparities between non-Hispanic whites and Hispanics in the United States
