A Qualitative Study on the Potential Utilization of a Mobile Phone for Obesity Management in Elementary-School Children : Parents Perspective: Bo Young Lee, Mi Young Park, Kirang Kim, Jea Eun Shim, Ji Yun Hwang; Korean J Community Nutr 2019;24(2):117-126. Published online April 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.2.117

OBJECTIVES
This study was conducted to investigate the current difficulties surrounding children's obesity management and evaluate the application of a mobile phone as a tool to overcome such difficulties of obesity management from the perspective of main caregivers of elementary school students.
METHODS
The qualitative data were collected through 3 focus group interviews including 6 full-time housewives, 7 mothers with overweight children, and 4 working mothers. Data were analyzed using a thematic approach.
RESULTS
The limitations of current children's obesity management included difficulty in diet management and exercise as well as challenges of setting goals and lack of support at the household and school levels. Mobile technology may be useful to overcome the current problems by providing real-time knowledge on diet management and physical activity, online compensation scheme according to goal setting, and interactive environmental supports at both household and school levels for promoting overall health.
CONCLUSIONS
The mobile-based multiple support program may assist in overcoming the current limitations of child obesity management by providing tailored information and by creating a more supportive environment.

OBJECTIVES
This study was conducted to investigate the current status and to suggest future directions for health management of teenagers who use healthy school tuck shops to improve teenagers' eating habits while reducing and preventing obesity.
METHODS
A total of 29 students (16 middle school students and 13 high school students) took part in the interview for this study, and the interview was conducted for each school's focus group by using qualitative research methodology.
RESULTS
The current status of using healthy school tuck shops and suggested future directions were divided into two categories. Personal barriers such as discrepancies between personal perceptions and behaviors and lack of food choice suitable to individual tastes can be solved by rebuilding the operating system to provide intuitive promotion of behavior and customized products through improvements in existing products and new product development. A lack of consistent management from low utilization convenience and difficulty in maintaining a constant purchase price can be handled by establishing a solution to restricted physical access for products, as well as seeking profit by improving distribution costs via continuous cooperation between the school and community.
CONCLUSIONS
Continuous funding and a system that reflects the needs and preferences of healthy school tuck shop users should be applied for sustainable operation of healthy school tuck shops to improve teenagers' eating habits.

OBJECTIVES
The purpose of this study is to analyze the current status of nutrition education programs for multicultural families and to provide policy suggestions for improvement.
METHODS
In-depth interviews of a total of 21 multicultural experts were conducted; 15 people were interviewed individually, while 6 people were interviewed in groups of three.
RESULTS
In-depth interviews revealed various problems related to the operation of nutrition education programs. The causes of problems were analyzed and categorized as four factors: systemic, practical, environmental and cultural. As for the systematic factors, insufficient linkage between related organizations and duplicate performance of several projects were identified as concerns Establishment of a control tower and strengthening the linkage among the related organizations may be needed to address this concern. With regard to practical factors, the study identified that language barriers, and lack of nutritional education media and tools translated into multicultural languages were limiting factors. These limitations the development of nutrition education materials that aretranslated into multiple languages, implementation of education programs that are different from the Korean education, and by providing interpreters. As for the environmental factors, low educational level and poor nutritional knowledge of multicultural women made it difficult for them to understand the contents of the education. Demonstration, practical training and urgent education on pregnancy and childbirth nutrition were identified as needs to address these concerns. Withregard to cultural factors, food culture conflict with Korean families, and difficulties in home practices were detected as concerns. Participants in the study suggested that getting education with family and facilitation of weekend and nighttime programs health of this community.
CONCLUSIONS
Further studies are needed to adopt more effective and efficient nutrition intervention to promote the healthy eating of the married immigrant women based on the study results.

Leveraging Multimodal Supports using Mobile Phones for Obesity Management in Elementary-School Children: Program Providers' Perspective from a Qualitative Study: Mi Young Park, Jae Eun Shim, Kirang Kim, Ji Yun Hwang; Korean J Community Nutr 2017;22(3):238-247. Published online June 30, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.3.238

Abstract PDF PubReader

OBJECTIVES
This study was conducted to investigate providers' perspectives on current challenges in implementing a program for prevention and management of childhood obesity and adoption of mobile phone as a potential solution of leveraging multimodal delivery and support in a school setting.
METHODS
The qualitative data were collected through face-to-face in-depth interviews with 23 elementary-school teachers, 6 pediatricians, and 6 dieticians from community health centers and analyzed using a qualitative research methodology.
RESULTS
Current challenges and potential solutions of obesity-prevention and -management program for obesity program for elementary school children were deduced as two themes each. Lack of tailored intervention due to limited recipient motivation, lack of individualized behavioral intervention, and different environmental conditions can be solvable by mobile technology-based personalized intervention which brings about interactive recipient participation, customized behavioral intervention, and ubiquitous accessibility. Lack of sustainable management due to stigmatization, limited interactions between program providers and inconsistent administrative support can be handled by multimodal support based on school setting using mobile platform providing education of health promoting behaviors toward larger scale and interactive networking between program participants, and minimizing administrative burden.
CONCLUSIONS
Adoption of mobile-based health management program may overcome current limitations of child obesity program such as lack of tailored intervention and sustainable management via personalized intervention and multimodal supports although some concerns such as increased screen time need to be carefully considered in a further study.

A Qualitative Study on Attitude, Acceptability, and Adaptation for Home-delivered Meal Services in the Korean Elderly from the Perspective of Life Context: Ji Yun Hwang, Bokyoung Kim, Kirang Kim; Korean J Community Nutr 2014;19(5):459-467. Published online October 31, 2014; DOI: https://doi.org/10.5720/kjcn.2014.19.5.459

Abstract PDF PubReader

OBJECTIVES
The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context.
METHODS
The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method.
RESULTS
The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used.
CONCLUSIONS
We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.

The Association between Changes in Food and Nutrient Intakes and Changes in Bone Metabolic Indicators in Postmenopausal Women with Osteopenia after a 12-week Intervention of Nutrition Education and Aerobic Exercise: Seo Jin Kim, Suh Jung Kang, Yoon Jung Park, Ji Yun Hwang; Korean J Community Nutr 2013;18(3):213-222. Published online June 30, 2013; DOI: https://doi.org/10.5720/kjcn.2013.18.3.213

Abstract PDF PubReader

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 < or = T-score < or = 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin B2 (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

Dietary Intakes and Eating Behaviors of Vietnamese Female Immigrants to Korea through Marriage and Korean Spouses and Correlations of Their Diets: Sun Hye Kim, Wha Young Kim, Ji Eun Lyu, Hye Won Chung, Ji Yun Hwang; Korean J Community Nutr 2009;14(1):22-30. Published online February 28, 2009

Abstract PDF: This study aimed to examine nutritional status and similarities of diets between Vietnamese female immigrants and Korean spouses and dietary changes of Vietnamese females after immigration. Subjects were 608 couples visiting 13 medical centers for the Cohort of Intermarried Women in Korea from November 2006 to November 2007. Anthropometric and biochemical measurements were obtained and dietary intakes were assessed using one-day 24-hour recall. Sixty-eight percent of wives answered there have been changes in their diets and consumptions of meats, fish, dairy products, vegetables, and fruits increased after immigration. Energy intakes of wives and spouses were 1491.7 kcal and 1788.8 kcal, respectively, showing most couples (80.1%) consumed less than the Korean estimated energy requirements. More than half of the couples were below the Korean estimated average requirements of zinc, vitamin B2, and folate. The correlation coefficients between couples ranged 0.15-0.38 for unadjusted, 0.22-0.35 for per 1000 kcal, and 0.21-0.40 for energyadjusted, respectively. The proportions of couples in the same quartiles of each nutrient intake and in the same answers of each question of Mini Dietary Assessment were about 30% across nutrients and around 50% across questions. The length of residence is related to similarities of nutrient intakes between couples: similarities decreased after 3 years of residence in Korea. In conclusion, nutritional intakes of inter-married couples were inadequate although wives reported that their dietary intakes increased after immigration. Inadequate nutrient intakes of wives were partly explained by similar diets between couples because these wives without enough adjustment to Korean culture were more likely to follow what their spouses ate. Findings from this study may be helpful to improve the nutritional status of inter-married couples and make policies and programs for them. A follow-up study should identify factors affecting inadequate nutritional status of intermarried couples and similarities of their diets.
