Socially and economically disadvantaged first-time mothers are at risk for intimate partner violence. In a randomized trial with 492 participants, Jack and colleagues found that augmentation of a nurse home visitation program with a comprehensive intimate partner violence intervention, compared with the home visitation program alone, did not improve quality of life at 24 months after delivery.

Visual Abstract and CME

Sedentary behaviors are associated with increased risks of obesity, cardiovascular disease, cancer, diabetes, and overall mortality. Yang and colleagues analyzed nationally representative surveys for 51 896 participants in the United States and found that estimated total sitting time increased among adolescents and adults and computer use during leisure time increased among all age groups.


Under the Affordable Care Act, states may expand Medicaid to adults with household incomes at or below 138% of the federal poverty level, which could improve access to health services and promote earlier use of prenatal care. Brown and colleagues compared outcomes for 15 631 174 US births and found that disparities in birth outcomes for black infants compared with white infants declined among states that expanded Medicaid vs those that did not.

Clinical Review & Education

Evaluating 2 or more interventions concurrently is an efficient use of resources and may enhance study recruitment by offering participants a higher probability of being allocated to a new intervention. In this extension of the CONSORT 2010 Statement, Juszczak and colleagues provide guidance to increase the transparency and accuracy of multi-arm parallel-group randomized clinical trials.
