Abstract PDF: Objectives
A mobile health intervention program was provided for employees with overweight and obesity for 12 weeks, and a process evaluation was completed at the end of the program. We investigated participant engagement based on app usage data, and whether engagement was associated with the degree of satisfaction with the program.
Methods
The program involved the use of a dietary coaching app and a wearable device for monitoring physical activity and body composition. A total of 235 employees participated in the program. App usage data were collected from a mobile platform, and a questionnaire survey on process evaluation and needs assessment was conducted during the post-test.
Results
The engagement level of the participants decreased over time. Participants in their 40s, high school graduates or lower education, and manufacturing workers showed higher engagement than other age groups, college graduates, and office workers, respectively. The overall satisfaction score was 3.6 out of 5. When participants were categorized into three groups according to their engagement level, the upper group was more satisfied than the lower group. A total of 71.5% of participants answered that they wanted to rejoin or recommend the program, and 71.9% answered that the program was helpful in improving their dietary habits. The most helpful components in the program were diet records and a 1:1 chat with the dietary coach from the dietary coaching app. The barriers to improving dietary habits included company dinners, special occasions, lack of time, and eating out. The workplace dietary management programs were recognized as necessary with a need score of 3.9 out of 5.
Conclusions
Participants were generally satisfied with the mobile health intervention program, particularly highly engaged participants. Feedback from a dietary coach was an important factor in increasing satisfaction.

Effectiveness of a mobile health intervention on weight loss and dietary behavior changes among employees with overweight and obesity: a 12-week intervention study investigating the role of engagement: Imhuei Son, Jiyoun Hong, Young-Hee Han, Bo Jeong Gong, Meng Yuan Zhang, Woori Na, Cheongmin Sohn, Taisun Hyun; Korean J Community Nutr 2023;28(2):141-159. Published online April 30, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.2.141

Objectives
This study aimed to determine whether a mobile health (mhealth) intervention is effective in reducing weight and changing dietary behavior among employees with overweight and obesity. The study also investigated whether engagement with the intervention affected its effectiveness.
Methods
The intervention involved the use of a dietary coaching app, a wearable device for monitoring physical activity and body composition, and a messenger app for communicating with participants and an intervention manager. A total of 235 employees were recruited for a 12-week intervention from eight workplaces in Korea. Questionnaire surveys, anthropometric measurements, and 24-h dietary recalls were conducted at baseline and after the intervention.
Results
After the intervention, significant decreases in the mean body weight, body mass index, body fat percentage, and waist circumference were observed. Furthermore, the consumption frequencies of multigrain rice and legumes significantly increased, whereas those of pork belly, instant noodles, processed meat, carbonated beverages, and fast food significantly decreased compared with those at baseline. The mean dietary intake of energy and most nutrients also decreased after the intervention. When the participants were categorized into three groups according to their engagement level, significant differences in anthropometric data, dietary behaviors, and energy intake were observed following the intervention, although there were no differences at baseline, indicating that higher engagement level led to greater improvements in weight loss and dietary behavior.
Conclusions
The intervention had positive effects on weight loss and dietary behavior changes, particularly among employees with higher engagement levels. These results indicate the importance of increasing the level of engagement in the intervention to enhance its effectiveness. The mhealth intervention is a promising model for health promotion for busy workers with limited time.

Association between Sarcopenia and Energy and Protein Intakes in Community-dwelling Elderly: Woori Na, Dayoung Oh, Seohyeon Hwang, Bonghee Chung, Cheongmin Sohn; Korean J Community Nutr 2022;27(4):286-295. Published online August 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.4.286

Abstract PDF

Objectives
Sarcopenia is one of the most representative factors of senescence, and nutritional status is known to affect sarcopenia. This study was performed to analyze the relationships between energy and protein intake and sarcopenia.
Methods
The study subjects were 3,236 individuals aged ≥ 65 that participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2008 ~ 2011. General characteristics and anthropometric and 24-hour dietary recall data were analyzed. Sarcopenia was diagnosed using a formula based on appendicular skeletal muscle mass (ASM) and body weight. Logistic regression was performed to determine relationships between sarcopenia risk and energy and protein intakes.
Results
For energy intake, the odds ratio (OR) of sarcopenia in women was significantly higher those with the lowest intake [OR = 1.680, 95% confidence interval (CI) = 1.213-2.326] than those with the highest intake (P for trend = 0.001). Regarding protein intake per kg of body weight, the odds ratio of sarcopenia was significantly higher for those that consumed < 0.8 g/kg of protein daily than those that consumed > 1.2g/kg for men (OR = 2.459, 95% CI = 1.481-4.085) and women (OR = 2.178, 95% CI = 1.423-3.334).
Conclusions
This study shows a link between sarcopenia and energy and protein intake levels and suggests that energy and protein consumption be promoted among older adults to prevent sarcopenia.

Association of Plasma Osteoprotegerin with Adiponectin and Difference according to Obesity in Men with Metabolic Syndrome: Woori Na, Cheongmin Sohn; Korean J Community Nutr 2011;16(6):762-770. Published online December 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.6.762

Abstract PDF PubReader: Osteoprotegerin (OPG) plays a core role in bone reformation by antagonizing the effect of receptor activator of nuclear factor kappa-B ligand (RANKL), and mediates vascular calcification in cardiovascular disease patients. Thus, we aimed to examine the relationship between serum OPG levels and cardiovascular factors and inflammatory markers in metabolic syndrome patients (MS). This cross-sectional study included 96 men who visited the diet clinic between May and July 2011. Patients were classified into 2 groups based on NCEP-ATP guidelines: normal and with MS (n = 50 and 46, respectively). Physical measurements, biochemical assay were measured. Serum OPG and IL-6, diponectin and hs-CRP were assessed. MS were aged 50.02 +/- 10.85 years, and normal patients 52.07 +/- 9.56 years, with no significant differences. Significant differences were not observed in BMI between the 2 groups. Moreover, significant differences were not observed in serum OPG, however, the serum OPG level (4.41 +/- 1.86 pmol/L) differed significantly between an overweight MS (BMI > 25) and normal patients. OPG was correlated to age (r = 0.410, p = 0.000), HDL-cholesterol (r = 0.209, p = 0.015), and log adiponectin (r = 0.175, p = 0.042). Multiple regression analyses using the enter method showed that age (beta = 0.412, p = 0.000) and BMI (beta = 0.265, p = 0.000) considerably affected OPG. In conclusion, out study showed that serum OPG levels are correlated with cardiovascular risk factors, such as BMI, HDL-cholesterol and adiponectin in MS and adiponectin, suggesting that serum OPG has potential as a cardiovascular disease indicator and predictor.

Relationship between Nutrients Intakes, Dietary Quality, and Serum Concentrations of Inflammatory Markers in Metabolic Syndrome Patients: Misung Kim, Juyoung Kim, Wookyung Bae, Sohye Kim, Yesong Lee, Woori Na, Cheongmin Sohn; Korean J Community Nutr 2011;16(1):51-61. Published online February 28, 2011; DOI: https://doi.org/10.5720/KJCN.2011.16.1.51

Abstract PDF PubReader

Elevated serum concentration of inflammation markers is known as an independent risk factor of metabolic syndrome (MS) and dietary intake is an important factor to control MS. The purpose of this study was to investigated the hypothesis that inflammatory indices are associated with dietary intake and diet quality index-international (DQI-I) in subjects with MS. A cross-sectional study was conducted on 156 men and 73 postmenopausal women with MS, defined by three or more risk factors of the modified Adult Treatment Panel III criteria. Serum levels of high sensitive C-reactive protein (hs-CRP), adiponectin were examined and nutrients intake and DQI-I were assessed using a semi-quantitative food frequency questionnaire. The total DQI-I score was significantly higher in female subjects (65.87 +/- 9.86) than in male subjects (62.60 +/- 8.95). There was a positive association between hs-CRP and polyunsaturated fatty acid intake (p < 0.05) and a negative association between adiponectin and lipid (p < 0.05), total sugar (p < 0.01), and total fatty acids (p < 0.05). When the subjects were divided into 5 groups by quintile according to serum adiponectin and hs-CRP level, there was no association between DQI-I score and hs-CRP levels. Moderation score of DQI-I was significantly higher in highest quintile group than the lower quintile groups. Therefore, our results provide some evidence that dietary intake and diet quality are associated with inflammation markers and dietary modification might be a predictor to decrease risk for metabolic syndrome complications. However further research is needed to develop the dietary quality index reflecting the inflammatory change by considering the dietary habit and pattern of Koreans.
