OBJECTIVES: To screen for Common Mental Disorders (CMD) among reproductive-aged women from rural western India and explore how the relationship between perceived stress and CMD screening status varies by sociodemographic characteristics.

METHODS: Cross-sectional survey of 700 women from rural Gujarat, India. …

Health Promotion Practice And The Road Ahead: Addressing Enduring Gaps And Encouraging Greater Practice-To-Research Translation, Amanda Birnbaum, Mark D. Rivera

Amanda Birnbaum

A decade ago, Lancaster and Roe described four critical gaps (i.e., communications, accessibility, credibility, and expectations) between research and practice in health education and health promotion that formed the framework for this department. Despite considerable attention and some progress, these gaps persist and are barriers to interaction and translation between health promotion and health education research and practice. Looking to the next several years as the new Associate Editors for this department, we renew the department’s commitment toward addressing these enduring gaps around which we frame new questions and invite continued dialogue.

The average age of the 4025 …

A Context-Aware Activity Recommendation Smartphone Application To Mitigate Sedentary Lifestyles, Qian He, Emmanuel Agu

Emmanuel O. Agu

A sedentary lifestyle involves irregular or no physical activity. In this kind of lifestyle, people’s activities do not increase their energy expenditure substantially above resting levels. Long periods of sitting, lying, watching television, playing video games, and using the computer are typical examples. Energy expenditures at 1.0-1.5 Metabolic Equivalent Units (METs) are considered sedentary behaviors. A recent study of sedentary lifestyles found that the length of sedentary times is associated with an increased risk of diabetes, cardiovascular disease, and cardiovascular and all-cause mortality. In this study, we developed a smartphone application called “On11”, which continuously tracks and informs the user …

Supporting Recovery In The Deaf Community: Creating Continuum Of Behavioral Health Care In Central Massachusetts, Melissa L. Anderson, Neil S. Glickman, Lisa Mistler, Susan Jones, Monika E. Kolodziej, Douglas M. Ziedonis

Melissa L. Anderson

Across the U.S., there is a paucity of mental health and substance abuse services for Deaf individuals. Without the availability of communication accommodations and specialized clinical expertise, Deaf individuals seeking behavioral health services contend with access limitations, misdiagnoses, and superficial treatments. Moreover, while the assessment and treatment of co-occurring disorders and the infusion of trauma-informed care are key components of effective treatment in the mainstream literature, the investigation and application of these initiatives to the Deaf population has not yet occurred. The proposed poster will outline the current state of specialized behavioral health services for Deaf individuals in Central Massachusetts, …

In-Hospital Depression Predicts Early Hospital Readmission After An Acute Coronary Syndrome: Preliminary Data From Trace-Core, David Mcmanus, Jane Saczynski, Molly Waring, Milena Anatchkova, Richard Mcmanus, Robert Goldberg, Jeroan Allison, David Parish, Hamza Awad, Jerry Gurwitz, Arlene Ash, Catarina Kiefe

Richard H. McManus

Background: Hospital systems, patients and providers seek to avert rehospitalizations within 30 days for patients admitted with an acute coronary syndrome (ACS). Rehospitalizations within 30 days of discharge are often considered preventable and to reflect poor in-hospital management or discharge practices. However, independent associations of psychosocial factors with early rehospitalization in patients admitted with an ACS have not been examined. Methods: A multi-racial cohort of 1,540 patients admitted with an ACS reported psychosocial factors via standardized questionnaires in an in-hospital interview. One month following discharge, patients were interviewed via phone and reported hospital readmissions. We used logistic regression models to …

Cluster Randomized Trials And Statistical Power, Stephen A. Lauer, Nicholas G. Reich

Nicholas G Reich

The cluster-randomized trial (CRT) is a common study design in public health research. In situations where dividing a group of individuals into treatment and controls is unethical or impossible, a CRT design maintains the strengths of a randomized study design. By comparing the outcomes of small populations (clusters), we can observe the impacts of interventions on the community as a whole. Public health researchers around the world have utilized CRTs to measure the effect of, for example, de-worming medication on school attendance, financial incentives on doctor absenteeism, and providing chlorine to waterholes. The CRT can be a potent tool, however …

History Of Fructose Use In Food Products, Jody L. Vogelzang Phd, Rdn, Fand, Ches

Jody L Vogelzang PhD, RDN, FAND, CHES

Food can be classified in ways other than by the nutrients they contain. In today’s fast moving culture, foods are characterized as having “magical” qualities that can turn consumers “superstars”, or reduce them to a less than optimal state of health and wellness. Sugars appear to be one of those vulnerable foodstuffs that can be enjoyed in moderation, but also contribute to the development of Type 2 Diabetes, metabolic syndrome, impaired cognitive function, obesity, and tooth decay .

Barriers And Facilitators To Addressing Perinatal Depression In Obstetric Settings, Nancy Byatt, Kathleen Biebel, Liz Friedman, Gifty Debordes-Jackson, Jeroan J. Allison, Douglas M. Ziedonis

Kathleen Biebel

Background: Perinatal depression is common and can cause suffering for mother, fetus/child and family. The perinatal period is an ideal time to detect and treat depression due to regular contact between mothers and health professionals. Despite the opportune time and setting, depression is under-diagnosed and under-treated in the obstetric setting. Caring and committed providers are frustrated and confused, and mothers do not feel heard or understood by their providers.

Objectives: (1) Identify postpartum women’s perspective on how perinatal depression is addressed in obstetric settings; (2) Identify strategies for improvement of the delivery of depression care in OB/Gyn settings; and, (3) …

Rates Of Insurance For Injured Patients Before And After Health Care Reform In Massachusetts: Another Case Of Double Jeopardy?, Heena P. Santry, Courtney E. Collins, Jason T. Wiseman, Julie M. Flahive, Charles M. Psoinos, Zeling Chau, Shimul A. Shah, Catarina I. Kiefe

Catarina I. Kiefe

Background: As a result of healthcare reform (HCR), insurance rates among Massachusetts (MA) residents increased from 86.6% (2006) to 94.4% (2010) and conferred a 7.6% higher probability of being insured compared to neighboring states. The effect of an individual mandate on insurance rates among trauma patients is unknown.

Methods: This was retrospective analysis of adult (18-64yrs) trauma patients from MA and surrounding states (NH, RI, CT, NY, VT) treated at our level 1 trauma center in central MA before (2004-2005) and after (2009-2010) MA-HCR. We estimated changes in insurance rates across time-periods and state-residence.
