    Parents and caregivers do not exist in a vacuum, and with regard to crafting impactful interventions, it is increasingly being recognized that there are no one-size-fits-all approaches to behavior change. Implementing research to practice is a complex endeavor and requires the adaptation of basic research findings to different cultural and environmental contexts of intended beneficiaries (Sepinwall, 2002; Weisner & Hay, 2014). The practice of formative research allows for the systematic assessment of diverse implementation contexts and provides insights into responsive adaptations of content and delivery. In this study, we detail the use of formative testing to inform the development of a curriculum designed to support the Universal Newborn Hearing Screening (UNHS): the Thirty Million Words Initiative Newborn (TMW-Newborn) Parent Education Curriculum provides caregivers of newborns with information on the UNHS and illustrates the importance of identifying if a newborn is deaf or hard of hearing (D/HH) to ensure that caregivers learn how to promote early language development. The information provided could potentially reduce lost-to-follow up (LFU) rates for newborns who may be D/HH. Using qualitative methods, we collected and responded to feedback obtained from caregivers of newborns and were able to gear content, messaging and delivery of the intervention to stakeholder needs. A subsample of participants also completed a knowledge survey testing their understanding of intervention content prior to receiving the intervention, as well as the day after. The results showed that participant scores increased significantly post-intervention

    New genetic loci link adipose and insulin biology to body fat distribution.

    Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

    Note: A full list of authors and affiliations appears at the end of the article. Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P 20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.</p
