Less Time for Health: Parenting, Work, and Time-Intensive Health Behaviors among Married or Cohabiting Men and Women in the United States.

Time spent working or caring for children may reduce the time available for undertaking time-intensive health behaviors. We test competing perspectives about how work hours and the number of children of specific ages will be associated with married or cohabiting men's and women's sleep duration and physical activity. We use data from the 2004 to 2017 waves of the National Health Interview Survey (N = 154,580).

Peer Network Processes in Adolescents' Health Lifestyles.

Combining theories of health lifestyles-interrelated health behaviors arising from group-based identities-with those of network and behavior change, we investigated network characteristics of health lifestyles and the role of influence and selection processes underlying these characteristics. We examined these questions in two high schools using longitudinal, complete friendship network data from the National Longitudinal Study of Adolescent to Adult Health. Latent class analyses characterized each school's predominant health lifestyles using several health behavior domains.

Adolescent Technology, Sleep, and Physical Activity Time in Two US Cohorts.

The advent of internet-enabled mobile digital devices has transformed US adolescent technology use over the last decade, yet little is known about how these changes map onto other health-related behaviors. We provide a national profile of how contemporary technology use fits into adolescents' daily health lifestyles compared to the previous generation, with particular attention to whether and for whom technology use displaces time spent in sleep or physical activity. Time diaries were collected from 11-17 year olds in 2002-03 (N=1,139) and 2014-16 (N=527) through the US Panel Study of Income Dynamics Child Development Supplement.

A life course framework for understanding digital technology use in the transition to adulthood.

Rapid increases in young people's time spent using digital technology ("screen time") in the mobile internet era have led to anxiety about long-term effects. This mixed-method US study examines childhood experiences and contextual factors that shape screen time in the transition to adulthood. We recursively analyzed 56 qualitative interviews with young adults in a large metropolitan area in 2016-2018 and prospective longitudinal nationally representative survey data (PSID-CDS-2007 and PSID-TAS-2017) to articulate a conceptual framework of life course influences on young adults' time spent using digital technologies.

Utilizing genome wide data to highlight the social behavioral pathways to health: The case of obesity and cardiovascular health among older adults.

We use genome-wide data from the 1992-2016 Health and Retirement Study (n = 12,090) to characterize obesity among older adults as genetically or socially oriented. To illustrate the significance of this approach for social epidemiological research, we deem those with the lowest genetic risk for obesity to be socially-behaviorally obese and obesity among those with the highest polygenic risk is characterized as genetically oriented. We then examine the association between obesity and four indicators of cardiovascular health (type-2 diabetes, hypertension, heart problems, and stroke) among those with low, average, and high genetic risk.

Mortality and Obesity Among U.S. Older Adults: The Role of Polygenic Risk.

Objectives: To examine the relationship between obesity and mortality as a function of polygenic risk for obesity among older U.S. adults.

Primary Arthroscopic Repair of the Anterior Cruciate Ligament: A Systematic Review of Clinical Outcomes.

Purpose: To describe the clinical outcomes after primary arthroscopic anterior cruciate ligament (ACL) repair.

Methods: A systematic review of the PubMed, Embase, and Cochrane Library databases was performed according to the PRISMA guidelines. All English-language literature published from 2000 to 2018 that reported the clinical outcomes after primary arthroscopic repair (AR) of complete tear of the ACL (without augmentation) with a minimum 2-year follow-up was reviewed by 2 independent reviewers.

Family Complexity, Siblings, and Children's Aggressive Behavior at School Entry.

As family structure in the United States has become increasingly dynamic and complex, children have become more likely to reside with step- or half-siblings through a variety of pathways. When these pathways are accounted for, more than one in six U.S.
