- ItemSelf-monitoring dietary intake: current and future practices.(2005-07-11) Burke, Lora E; Warziski, Melanie; Starrett, Terry; Choo, Jina; Music, Edvin; Sereika, Susan; Stark, Susan; Sevick, Mary AnnThis article reviews the literature on the use of paper diaries for self monitoring food intake identifies the strengths and limitations of paper and pencil diaries and their new counterpart the electronic diary or personal digital assistant PDA and reports how participants were trained to use a PDA with dietary software in two pilot studies one with hemodialysis patients and the other with participants in a weight loss study The report of the pilot studies focuses on the practical issues encountered in training participants in the use of a PDA and addresses the pros and cons of different dietary software programs Six hemodialysis patients were trained in the first study and seven participants attempting to lose or maintain their weight were trained in the second pilot study The training focused on how to use a PDA and how to navigate the dietary software to self monitor food intake The goals of using the PDA were to improve adherence to the therapeutic diets and to self monitoring Lessons learned from the pilot studies are shared
- ItemSelf-monitoring in weight loss: a systematic review of the literature.(2010-12-27) Burke, Lora E; Wang, Jing; Sevick, Mary AnnSelf monitoring is the centerpiece of behavioral weight loss intervention programs This article presents a systematic review of the literature on three components of self monitoring in behavioral weight loss studies diet exercise and self weighing This review included articles that were published between 1993 and 2009 that reported on the relationship between weight loss and these self monitoring strategies Of the 22 studies identified 15 focused on dietary self monitoring one on self monitoring exercise and six on self weighing A wide array of methods was used to perform self monitoring the paper diary was used most often Adherence to self monitoring was reported most frequently as the number of diaries completed or the frequency of log ins or reported weights The use of technology which included the Internet personal digital assistants and electronic digital scales were reported in five studies Descriptive designs were used in the earlier studies whereas more recent reports involved prospective studies and randomized trials that examined the effect of self monitoring on weight loss A significant association between self monitoring and weight loss was consistently found however the level of evidence was weak because of methodologic limitations The most significant limitations of the reviewed studies were the homogenous samples and reliance on self report In all but two studies the samples were predominantly white and women This review highlights the need for studies in more diverse populations for objective measures of adherence to self monitoring and for studies that establish the required dose of self monitoring for successful outcomes
- ItemSMART trial: A randomized clinical trial of self-monitoring in behavioral weight management-design and baseline findings.(2009-10-28) Burke, Lora E; Styn, Mindi A; Glanz, Karen; Ewing, Linda J; Elci, Okan U; Conroy, Margaret B; Sereika, Susan M; Acharya, Sushama D; Music, Edvin; Keating, Alison L; Sevick, Mary AnnBACKGROUND The primary form of treatment for obesity today is behavioral therapy Self monitoring diet and physical activity plays an important role in interventions targeting behavior and weight change The SMART weight loss trial examined the impact of replacing the standard paper record used for self monitoring with a personal digital assistant PDA This paper describes the design methods intervention and baseline sample characteristics of the SMART trial METHODS The SMART trial used a 3 group design to determine the effects of different modes of self monitoring on short and long term weight loss and on adherence to self monitoring in a 24 month intervention Participants were randomized to one of three conditions 1 use of a standard paper record PR 2 use of a PDA with dietary and physical activity software PDA or 3 use of a PDA with the same software plus a customized feedback program PDA FB RESULTS We screened 704 individuals and randomized 210 There were statistically but not clinically significant differences among the three cohorts in age education HDL cholesterol blood glucose and systolic blood pressure At 24 months retention rate for the first of three cohorts was 90 CONCLUSIONS To the best of our knowledge the SMART trial is the first large study to compare different methods of self monitoring in a behavioral weight loss intervention and to compare the use of PDAs to conventional paper records This study has the potential to reveal significant details about self monitoring patterns and whether technology can improve adherence to this vital intervention component
