Static and dynamic work involving the arms and the legs was performed by 40 men seven weeks after myocardial infarction. Leg ergometry produced a significantly higher peak work load, systolic blood pressure (BPs), heart rate (HR), and HR X BPs X 10(-2) product (DP) than did arm ergometry: 842 +/- 178 vs 546 +/- 135 kg-m/min, 176 +/- 24 vs 154 +/- 19 mm Hg(More)
An asymptomatic adult population of 196 men and women was studied with the echocardiogram to derive age- and sex-specific "normal" values for a number of clinically used echocardiograhic variables. The results are in general agreement with previously published normal values. Body position during the examination, age and sex influence the echocardiographic(More)
During childhood, patients with Type 1 diabetes (T1D) are reliant on an informal caregiver (parent or guardian) for day-to-day disease management. Upon entering adolescence, patients are expected to adopt a greater role in self-management. However, adolescents often have difficulty adhering to management regimens, which can lead to poor health outcomes.(More)
BACKGROUND As consumer health information technology (IT) becomes more thoroughly integrated into patient care, it is critical that these tools are appropriate for the diverse patient populations whom they are intended to serve. Cultural differences associated with ethnicity are one aspect of diversity that may play a role in user-technology interactions.(More)
BACKGROUND Obtaining access to a demographically and geographically diverse sample for health-related research can be costly and time consuming. Previous studies have reported mixed results regarding the potential of using social media-based advertisements to overcome these challenges. OBJECTIVE Our aim was to develop and assess the feasibility, benefits,(More)
Family health history contains important information about the genetic and environmental factors that contribute to patterns of health and illness in families. Applications for collecting, managing, and analyzing family health history could be improved if their design were informed by an understanding of how consumers think about and report family health(More)
OBJECTIVES This review applied a human factors/ergonomics (HF/E) paradigm to assess individual, work system/unit, organization, and external environment factors generating barriers to patient, provider, and informal caregiver personal health record (PHR) use. METHODS The literature search was conducted using five electronic databases for the timeframe(More)
Human factors/ergonomics recognises work as embedded in and shaped by levels of social, physical and organisational context. This study investigates the contextual or macroergonomic factors present in the health-related work performed by patients. We performed a secondary content analysis of findings from three studies of the work of chronically ill(More)
BACKGROUND Consumer health information technology (IT) solutions are designed to support patient health management and have the ability to facilitate patients' health information communication with their social networks. However, there is a need for consumer health IT solutions to align with patients' health management preferences for increased adoption of(More)
