Filter by:Sleep is a clearly necessary neurobiologic process that influences innumerable aspects of basic daily functions, physical health, and mental well-being. Recent literature shows that college students across the country are experiencing high rates of sleep deprivation. Interestingly, some recent studies have implicated this sleep loss in contributing to weight gain that occurs in the first year of college, also known as the "freshman fifteen." Rates of depression and other mental health issues, which are closely connected to sleep disturbances, are also on the rise in college campuses. The majority of the sleep data obtained in this population has been via questionnaires and self report, and the studies usually include college students at all seniority levels (e.g., freshmen, sophomores, seniors). Here, the investigators outline a novel study investigating how sleep time changes in college freshman, and how it relates to multiple different aspects of their health and functioning over the course of one quarter. As technology has advanced, the ability to easily obtain objective measurements of different health parameters has increased dramatically. The investigators plan to use wireless actigraphy devices to measure sleep over a baseline seven day period in college-bound UCSD students prior to matriculation, and for 2 additional seven day periods during the first quarter of college. To the knowledge of the investigators, this is the first study to directly measure sleep time in college freshman in their normal environment. Effects of sleep time loss will be evaluated through multiple different metrics of physical and mental health. Given the recent link between sleep disturbances and weight gain in college freshman, the investigators will plan to measure weight changes prior to entering college and at two different time points through the first quarter. The investigators will use the PSQ-9 and GAD7 batteries as measures of mental health, obtained at the same time points as the sleep and weight information. As one of the primary consequences of sleep deprivation is on neurocognition in the daytime, the investigators plan to measure vigilant attention using psychomotor vigilance testing (PVT) as well. Screen time use has recently been targeted as a possible contributor to sleep loss in adolescents as well as adults and is something the investigators will attempt to measure as well using a smartphone application. Finally, this project will test the efficacy of a one hour sleep education intervention on improving total sleep time. To the knowledge of the investigators, no other studies have closely examined how total sleep time changes during the first year of college in freshman in relationship to weight and mental health parameters, nor has PVT been done in this context. Additionally, with the increasing concerns regarding screen time use in adolescents and young adults, this study provides prime opportunity to examine this issue in the context of sleep.
This project will develop and evaluate an interactive blood pressure self-management program for adults with prehypertension. The program will target blood pressure self-monitoring and the five proven lifestyle modifications recommended by JNC-7: weight reduction, the Dietary Approaches to Stop Hypertension (DASH) diet, sodium reduction, physical activity, and alcohol consumption. The multi-modal program uses a combination of brief motivational health coaching, periodic engagement emails, and a robust interactive website to motivate people to take charge of their blood pressure management before they require medication. All program components were designed to conform to the underlying principles of motivational interviewing. Key program components include the use of email and Web-based social networking, personal stories, and a brief motivational coaching session to engage participants and encourage intrinsically motivated behavior changes. Self-assessment and tracking tools are combined with educational content to help participants align their daily lifestyle choices with their personal goals. The Phase I prototype program promoted moderate physical activity and eating fruits and vegetables as part of the DASH diet. Results from the within-group (n = 39) evaluation showed moderate-to-large effect sizes for pre-to-post change in motivation, preparation behavior, self-efficacy, attitudes, and knowledge, and a small significant increase in physical activity. Participants gave the online program high ratings on satisfaction and usability, and reported improvements in confidence, readiness, clarity, change strategies, and interest in visiting the Website as a result of the coaching session. The fully developed Phase II product will be evaluated in a large randomized trial (N = 450) with a 3-month intensive intervention, a 3-month maintenance intervention, and a 3-month follow-up period. The Phase II trial is expected to show reductions in blood pressure and improvements in JNC-recommended health behaviors. These changes in the outcome measures are expected to be mediated by changes in knowledge, attitudes, self-efficacy, behavioral intention, motivation, and patient activation.
The purpose of the PaTH Clinical Data Research Network (CDRN) Study of Healthy Lifestyles, Body Weight and Health Care is to use clinical data from electronic health records (EHR) and patient reported outcomes (PRO) to answer questions of clinical importance to patients, providers, and other stakeholders.
