In particular, to determine what types of communication facilitate or prevent patient engagement and adherence to certain health behaviors related to smoking cessation, engagement in physical activity, healthy eating and healthy weight gain, and stress management. Methods: Participants were recruited from the obstetric and midwifery clinics at the University of Colorado Hospital. Twenty-four pregnant, English-speaking women between the ages of 18 and 46 years old, the majority of which had full health insurance coverage, participated in one of three focus groups that were conducted. The transcripts were coded for themes and patterns. Results identified numerous current practices of HCPs, facilitators and barriers in care, and patient recommendations related to effective patient-provider communication. Results: Overall many women received basic information about most health behaviors (i.e. healthy eating, physical activity, and smoking cessation) with the exception of stress management from their HCPs via their introductory information packet. However, typically there was no follow-up beyond receipt of the packet. As a result, women sought information online from numerous sources. Unfortunately, this information often conflicted with HCP provided information, as did the information provided from multiple HCPs in group care settings. A major facilitator of behavioral change pertained to building trust and rapport as it directly enhanced the perceived quality of patient-provider communication on prenatal health behaviors. Across all behaviors, women voiced the need for available resources that were credible and referenced by their HCPs. Conclusions: These findings provide a better understanding of what facilitates and prevents women from engaging in healthy behaviors during their pregnancy, in addition to improving patient and provider communication.展开更多

The aim of this study was to assess the validity of 3 WMs(Acti Graph GT3X+; activ PAL, and Sense Wear 2) in estimating the intensity of SB and LPA in adults as compared with the criterion measure of oxygen uptake(VO_2) measured by indirect calorimetry.Methods: Sixteen participants(age: 25.38 ± 8.58 years) wore the ActiG raph GT3X+, activP AL, and SenseW ear 2 devices during 7 sedentary-to-light activities. VO_2(mL/kg/min) was estimated by means of a portable gas analyzer, Oxycon Mobile(Carefusion, Yorba Linda, CA, USA). All data were transformed into metabolic equivalents and analyzed using mean percentage error, equivalence plots, Bland-Altman plots, kappa statistics, and sensitivity/specificity.Results: Mean percentage error was lowest for the activ PAL for SB(14.9%) and LPA(9.3%) compared with other WMs, which were >21.2%.None of the WMs fell within the equivalency range of ±10% of the criterion mean value. Bland-Altman plots revealed narrower levels of agreement with all WMs for SB than for LPA. Kappa statistics were low for all WMs, and sensitivity and specificity varied by WM type.Conclusion: None of the WMs tested in this study were equivalent with the criterion measure(VO_2) in estimating sedentary-to-light activities;however, the activ PAL had greater overall accuracy in measuring SB and LPA than did the Acti Graph and Sense Wear 2 monitors.展开更多

This study was designed to determine the feasibility of using pedometers to assess daily steps taken in a sub-sample of adults from Maricopa County who completed the 2014 Arizona Behavioral Risk Factor Surveillance System Survey.Methods: Respondents were sent an Omron HJ324 U pedometer, a logbook to record steps taken, and a walking questionnaire. The pedometer was worn for 7 days. Feasibility was assessed for acceptability(interest in study), demand(procedures followed correctly), implementation(time to complete study), and practicality(cost).Results: Acceptability was modest with 23.9%(830/3476) agreeing to participate. Among those participating(92.9%; 771/830), 50.1%(386/771)returned the logbook. Demand was modest with 39.3%(303/771) of logbooks returned with valid data. Implementation represented 5 months to recruit participants. The cost to obtain valid step-count data was USD61.60 per person. An average of 6363 ± 3049 steps/day were taken with most participants classified as sedentary(36.0%) or low active(35.6%).Conclusion: The feasibility of using pedometers in a state-based surveillance system is modest at best. Feasibility may potentially be improved with easy-to-use pedometers where data can be electronically downloaded.展开更多
