Abstract
BACKGROUND This section defined time use (TU) research, illustrating its relevance for public health. TUR in the health context is the study of health-enhancing and health-compromising behaviours that are assessed across a 24 h day. The central measurement is the use of Time Use Diaries, which capture 24-48 h, typically asking about behaviour in each 15-min period. TUR is used for understanding correlates of health behaviours, and as a form of population surveillance, assessing behavioural trends over time. MAIN BODY This paper is a narrative review examining the history of time use research, and the potential uses of TU data for public health research. The history of TUR started in studies of the labour force and patterns of work in the late 19th and early twentieth century, but has more recently been applied to examining health issues. Initial studies had a more economic purpose but over recent decades, TU data have been used to describe the distribution and correlates of health-enhancing patterns of human time use. These studies require large multi-country population data sets, such as the harmonised Multinational Time Use Study hosted at the University of Oxford. TU data are used in physical activity research, as they provide information across the 24-h day, that can be examined as time spent sleeping, sitting/standing/light activity, and time spent in moderate-vigorous activities. TU data are also used for sleep research, examining eating and dietary patterns, exploring geographic distributions in time use behaviours, examining mental health and subjective wellbeing, and examining these data over time. The key methodological challenge has been the development of harmonised methods, so population TU data sets can be compared within and between-countries and over time. CONCLUSIONS TUR provides new methods for examining public health research questions where a temporal dimension is important. These time use surveys have provided unique data over decades and in many countries that can be compared. They can be used for examining the effects of some large public health interventions or policies within and between countries.

Effectiveness of Interventions for Promoting Objectively Measured Physical Activity of Adults With Type 2 Diabetes: A Systematic Review.

Journal of physical activity & health. 2017;(5):408-415
Abstract
BACKGROUND Many people with type 2 diabetes (T2D) are sedentary despite strong recommendations of regular physical activity (PA). Objective measures of PA provide accurate reflection of daily PA level. The purpose of this review was to analyze studies used pedometers or accelerometers to determine the outcome of interventions promoted daily PA in people with T2D. METHODS An electronic literature search was conducted using the PubMed and CINAHL databases (2000-2016), with search terms: sedentary, diabetes, pedometer, physical activity, and accelerometer. Only peer-reviewed, randomized clinical trials (RCTs) that used objective measurement of daily PA level were included. All studies design, participant characteristics, intervention, and key findings were evaluated systematically and summarized. RESULTS A total of 15 RCTs were identified investigated objectively measured daily PA in people with T2D. A significant increase in PA was found following exercise consultation, behavioral/cognitive consultation, continuous glucose monitoring counseling, and motivational phone calls promoting PA. However, this increase in daily PA level was evident only during the intervention period. CONCLUSIONS Our systematic review of the literature indicated that a variety of interventions approaches were effective in increasing PA temporarily during the intervention period. Interventions that use objective methods in measuring PA and have long term improvement in overall PA are needed.

Utility of Consumer Physical Activity Trackers as an Intervention Tool in Cardiovascular Disease Prevention and Treatment.
Hickey, AM, Freedson, PS
Progress in cardiovascular diseases. 2016;(6):613-9
Abstract
Consumer activity trackers have grown in popularity over the last few years. These devices are typically worn on the hip or wrist and provide the user with information about physical activity measures such as steps taken, energy expenditure, and time spent in moderate to vigorous physical activity. The consumer may also use the computer interface (e.g. device websites, smartphone applications) to monitor and track achievement of PA goals and compete with other users. This review will describe some of the most popular consumer devices and discuss the user feedback tools. We will also present the limited evidence available about the accuracy of these devices and highlight how they have been used in cardiovascular disease management. We conclude with some recommendations for future research, focusing on how consumer devices might be used to assess effectiveness of various cardiovascular treatments.

Behavior change techniques implemented in electronic lifestyle activity monitors: a systematic content analysis.
Lyons, EJ, Lewis, ZH, Mayrsohn, BG, Rowland, JL
Journal of medical Internet research. 2014;(8):e192
Abstract
BACKGROUND Electronic activity monitors (such as those manufactured by Fitbit, Jawbone, and Nike) improve on standard pedometers by providing automated feedback and interactive behavior change tools via mobile device or personal computer. These monitors are commercially popular and show promise for use in public health interventions. However, little is known about the content of their feedback applications and how individual monitors may differ from one another. OBJECTIVE The purpose of this study was to describe the behavior change techniques implemented in commercially available electronic activity monitors. METHODS Electronic activity monitors (N=13) were systematically identified and tested by 3 trained coders for at least 1 week each. All monitors measured lifestyle physical activity and provided feedback via an app (computer or mobile). Coding was based on a hierarchical list of 93 behavior change techniques. Further coding of potentially effective techniques and adherence to theory-based recommendations were based on findings from meta-analyses and meta-regressions in the research literature. RESULTS All monitors provided tools for self-monitoring, feedback, and environmental change by definition. The next most prevalent techniques (13 out of 13 monitors) were goal-setting and emphasizing discrepancy between current and goal behavior. Review of behavioral goals, social support, social comparison, prompts/cues, rewards, and a focus on past success were found in more than half of the systems. The monitors included a range of 5-10 of 14 total techniques identified from the research literature as potentially effective. Most of the monitors included goal-setting, self-monitoring, and feedback content that closely matched recommendations from social cognitive theory. CONCLUSIONS Electronic activity monitors contain a wide range of behavior change techniques typically used in clinical behavioral interventions. Thus, the monitors may represent a medium by which these interventions could be translated for widespread use. This technology has broad applications for use in clinical, public health, and rehabilitation settings.
