      • Increasing Prevalence of Metabolic Syndrome in Korea : The Korean National Health and Nutrition Examination Survey for 1998–2007

        Lim, Soo,Shin, Hayley,Song, Jung Han,Kwak, Soo Heon,Kang, Seon Mee,Won Yoon, Ji,Choi, Sung Hee,Cho, Sung Il,Park, Kyong Soo,Lee, Hong Kyu,Jang, Hak Chul,Koh, Kwang Kon American Diabetes Association 2011 Diabetes care Vol.34 No.6

        <P><B>OBJECTIVE</B></P><P>The number of people with metabolic syndrome is increasing worldwide, and changes in socioenvironmental factors contribute to this increase. Therefore, investigation of changes in metabolic syndrome and its components in South Korea, where rapid socioenvironmental changes have occurred in recent years, would be foundational in setting up an effective strategy for reducing this increasing trend.</P><P><B>RESEARCH DESIGN AND METHODS</B></P><P>We compared the prevalence and pattern of metabolic syndrome among participants in the Korean National Health and Nutrition Examination Surveys for 1998, 2001, 2005, and 2007. In each survey, stratified, multistage, probability–sampling designs and weighting adjustments were conducted to represent the entire Korean population. The revised National Cholesterol Education Program criteria were used as the definition of metabolic syndrome. All biochemical parameters were measured in a central laboratory.</P><P><B>RESULTS</B></P><P>A total of 6,907 (mean ± SE age 45.0 ± 0.2 years), 4,536 (45.5 ± 0.2), 5,373 (47.1 ± 0.2), and 2,890 (49.9 ± 0.3) Koreans over 20 years of age have participated in the studies in 1998, 2001, 2005, and 2007, respectively. The age-adjusted prevalence of metabolic syndrome increased significantly from 24.9% in 1998, 29.2% in 2001, and 30.4% in 2005 to 31.3% in 2007. Among the five components, the level of low HDL cholesterol increased the most, by 13.8% over the 10 years. Abdominal obesity and hypertriglyceridemia followed, with 8.7 and 4.9% increases, respectively.</P><P><B>CONCLUSIONS</B></P><P>Because dyslipidemia and abdominal obesity were major factors in increasing the prevalence of metabolic syndrome in Koreans for the past 10 years, lifestyle interventions should be conducted at the national level to reduce the burden and consequences of metabolic syndrome.</P>

        Improved Glycemic Control Without Hypoglycemia in Elderly Diabetic Patients Using the Ubiquitous Healthcare Service, a New Medical Information System

        Lim, Soo,Kang, Seon Mee,Shin, Hayley,Lee, Hak Jong,Won Yoon, Ji,Yu, Sung Hoon,Kim, So-Youn,Yoo, Soo Young,Jung, Hye Seung,Park, Kyong Soo,Ryu, Jun Oh,Jang, Hak C. American Diabetes Association 2011 Diabetes care Vol.34 No.2

        <P><B>OBJECTIVE</B></P><P>To improve quality and efficiency of care for elderly patients with type 2 diabetes, we introduced elderly-friendly strategies to the clinical decision support system (CDSS)-based ubiquitous healthcare (u-healthcare<B>)</B> service, which is an individualized health management system using advanced medical information technology.</P><P><B>RESEARCH DESIGN AND METHODS</B></P><P>We conducted a 6-month randomized, controlled clinical trial involving 144 patients aged >60 years. Participants were randomly assigned to receive routine care (control, <I>n</I> = 48), to the self-monitored blood glucose (SMBG, <I>n</I> = 47) group, or to the u-healthcare group (<I>n</I> = 49). The primary end point was the proportion of patients achieving A1C <7% without hypoglycemia at 6 months. U-healthcare system refers to an individualized medical service in which medical instructions are given through the patient’s mobile phone. Patients receive a glucometer with a public switched telephone network-connected cradle that automatically transfers test results to a hospital-based server. Once the data are transferred to the server, an automated system, the CDSS rule engine, generates and sends patient-specific messages by mobile phone.</P><P><B>RESULTS</B></P><P>After 6 months of follow-up, the mean A1C level was significantly decreased from 7.8 ± 1.3% to 7.4 ± 1.0% (<I>P</I> < 0.001) in the u-healthcare group and from 7.9 ± 1.0% to 7.7 ± 1.0% (<I>P</I> = 0.020) in the SMBG group, compared with 7.9 ± 0.8% to 7.8 ± 1.0% (<I>P</I> = 0.274) in the control group. The proportion of patients with A1C <7% without hypoglycemia was 30.6% in the u-healthcare group, 23.4% in the SMBG group (23.4%), and 14.0% in the control group (<I>P <</I> 0.05).</P><P><B>CONCLUSIONS</B></P><P>The CDSS-based u-healthcare service achieved better glycemic control with less hypoglycemia than SMBG and routine care and may provide effective and safe diabetes management in the elderly diabetic patients.</P>

        A Survey on Ubiquitous Healthcare Service Demand among Diabetic Patients

        임수,김정임,권민경,민세진,유수영,강선미,김홍일,정혜승,박경수,류준옥,Shin Hayley,장학철,김소연 대한당뇨병학회 2011 Diabetes and Metabolism Journal Vol.35 No.1

        Background: Advanced information technology can be used when developing diagnostic and treatment strategies to provide better care for diabetic patients. However, the levels of need and demand for the use of technological advances have not been investigated in diabetic patients. We proposed and developed an individualized, ubiquitous (U)-healthcare service using advanced information technology for more effective glucose control. Prior to our service initiation, we surveyed patient needs and other pertinent information. Methods: During August 2009, we conducted a 34-item questionnaire survey among patients with diabetes who were older than 40 years in two certain hospitals in Korea. Results: The mean age of the 228 participants was 61.2±9 years, and males made up 49.1% of the sample. Seventy-one percent replied that they wanted individualized healthcare service, and they also wanted their health information to be delivered through mobile devices such as a cellular phone or a personal digital assistant (40.4%). Most patients had never heard of U-healthcare services (81.1%); however, after explaining the concept, 71.1% of participants responded that they would use the service if it was provided. Despite their willingness, participants were concerned about technical difficulty in using the service (26.3%) as well as the cost of the service (29.8%). Conclusion: The current study suggests that more than 70% of diabetic patients are interested in using U-healthcare services. To encourage widespread use, the application program or device of U-healthcare services should be simple, easy to use and affordable while also including a policy for the protection of private information.
