Health-related quality of life and nutrient intake of the elderly with type 2 diabetes according to comorbidity burden: a cross-sectional study: Yejung Choi, Kyong Park; Korean J Community Nutr 2024;29(5):418-430. Published online October 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00014

Abstract PDF PubReader ePub: Objectives
This study aimed to explore the cross-sectional association between health-related quality of life (HRQoL) according to the number of comorbidities in older adults with type 2 diabetes mellitus (T2DM) using the Euro Quality of Life-5 Dimensions (EQ-5D) index. Methods: This study included 3,553 participants aged ≥ 65 years from the 2008–2020 Korea National Health and Nutrition Examination Survey. Dietary data were collected through 24-hour recall interviews by trained researchers, and demographic and lifestyle information via self-administered questionnaires. HRQoL was measured using a modified EQ-5D scale. Multivariable linear regression analyzed the associations between EQ-5D scores, nutrients and comorbidity, controlling for sociodemographic and health variables. Results: Most participants reported ‘no problems’ in the EQ-5D scores, although approximately 17% to 47% of participants reported ‘some problems’ or ‘extreme problems,’ depending on the dimension. As comorbidities increased, significant declines were observed across all dimensions, particularly in mobility, usual activities, pain/discomfort, and anxiety/ depression. Nutrient intake analysis revealed that participants with three or more comorbidities consumed less carbohydrates, but more fat. Conclusion: Our findings demonstrate that among older adults with T2DM, a higher number of comorbidities is associated with decreased HRQoL. Additionally, there are differences in nutrient intake patterns among those with more comorbidities, specifically decreased carbohydrate intake and increased fat intake. These results emphasize the need for comprehensive and tailored management strategies that consider both diabetes and the co-occurring health conditions. By addressing the complex healthcare needs of individuals with multiple comorbidities, it is possible to enhance their HRQoL and overall well-being.

Food purchase patterns, food policy recognition, and food environment satisfaction among adults in Jeju, Korea, according to food security: a cross-sectional study: Sumin Kim, Youjeong Jang, Hyunji Ham, Hanbin Ko, Insuk Chai, Kyungho Ha; Korean J Community Nutr 2024;29(5):406-417. Published online October 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00012

Abstract PDF Supplementary Material PubReader ePub: Objectives
Recently, food insecurity has been a major public health issue along with the food crisis caused by COVID-19, climate change, and the polarization of food supply due to socioeconomic disparities. Food insecurity is known to be related to the food choices and environment of the consumer. Therefore, this study aimed to evaluate the food security statuses of adults in Jeju and investigate their food purchase patterns, food policy recognition, and food environment satisfaction.
Methods
Based on data from the 2022 Jeju Food Survey, 346 adults aged ≥19 years in Jeju were classified into food security and insecurity groups (quantitatively and qualitatively) using the questionnaire. Food purchase patterns, including purchasing frequency, items, and reasons, were surveyed for local and eco-friendly foods. The recognition and necessity of several food policies and satisfaction with diet and food environment (availability, accessibility, affordability, accommodation, and acceptability) were measured using the Likert scale.
Results
Among the total participants, 47.4% were in the food insecurity group. The frequency of purchasing local and eco-friendly foods did not significantly differ by food security status. The insecurity group exhibited a higher recognition rate of basic rights to food (36.0%) than the security group (24.7%, P = 0.023). The recognition and necessity of specific food policies did not significantly differ by food security status, except for the policy of promoting food communities, for which the food security group exhibited higher recognition than the food insecurity group did (P = 0.004). The food insecurity group exhibited significantly lower scores regarding satisfaction toward diet and food environment factors (P < 0.05 for all).
Conclusions
Overall, the food security group reported higher satisfaction with their diet and food environment than the food insecurity group. Further in-depth studies to investigate the determinants of food insecurity and effective promotional strategies for food policies are needed.

Sex differences in health-related quality of life among older Korean adults with type 2 diabetes mellitus: a cross-sectional study: Hyeonji Jeong, Kyong Park; Korean J Community Nutr 2024;29(4):336-347. Published online August 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00003

Abstract PDF PubReader ePub: Objectives
This cross-sectional study examined sex differences in Health-Related Quality of Life (HRQoL) among seniors with Type 2 Diabetes Mellitus (T2DM).
Methods
Data from the Korea National Health and Nutrition Examination Survey (2008–2020) were analyzed. The EuroQol-5 Dimensions (EQ-5D), a measure of HRQoL, was used. It comprises five dimensions: mobility, self-care, usual activity, pain/discomfort, and anxiety/depression, each with three levels.
Results
Analysis of 3,826 older adults with T2DM showed a significant increasing trend in the EQ-5D Index from the 4th survey phase onwards (P for trend < 0.001 for both men and women). Men consistently reported higher EQ-5D levels than women across all survey years. Women’s EQ-5D levels remained lower than men’s, maintaining a decade-old disparity (P < 0.05). Men scored significantly higher (P < 0.05) in most EQ-5D domains, except for self-care and anxiety/depression, resulting in a higher total EQ-5D Index (P = 0.001). Increased comorbidities were strongly associated with lower EQ-5D levels in both sexes. Additionally, there was a negative correlation between the EQ-5D Index and refined grain intake for both sexes (P for trend < 0.001), with high-EQ-5D groups consuming fewer refined grains. Women in the high-EQ-5D group consumed more nuts, vegetables, and meat compared to men (P for trend < 0.05).
Conclusions
Our study highlights the sex disparities in HRQoL among older adults with T2DM. The findings suggest the need for tailored treatment guidelines aimed at improving the HRQoL of elderly T2DM patients, with a focus on their sex-specific characteristics. Implementing these tailored guidelines could enhance the HRQoL of older women with T2DM and promote more equitable healthcare outcomes. This underscores the importance of considering sex differences to comprehensively improve the well-being of this population.

Effect of Nutrition Education on the Eating Habits and Quality of Life of Gastric Cancer Outpatients Undergoing Gastrectomy: YoonHee Jung, Joomin Lee; Korean J Community Nutr 2018;23(2):162-173. Published online April 30, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.2.162

Abstract PDF PubReader: OBJECTIVES
This study examined the effects of nutrition education on the nutritional status, including eating habits and quality of life in gastric cancer patients undergoing a gastrectomy.
METHODS
Thirty one out-gastric resection patients at C University Hospital in Gwangju, Korea were enrolled in this study. The patients received an individualized nutritional counseling session, and the effects were assessed before and after a 3-month nutrition education intervention. Nutrition education for gastric cancer outpatients included the dietary guidelines (e.g., food intake), the level of nutrient intake, and nutrition support.
RESULTS
The patients had significantly improved serum albumin and hematocrit levels after nutrition education. Of the dietary habits, the meal time and amount of food compared to the first education were increased significantly. Of the changes in the food intake frequency, fish and meat, and vegetables and fruits intake were increased, but not at a statistically significant level. The score of eating habits related to the gastrectomy was improved significantly after nutrition education from 31.7 to 34.5. The composite scores for the quality of life were also improved significantly after the nutrition education program.
CONCLUSIONS
The nutrition education for gastric cancer outpatients may be crucial and efficient for improving their lifestyle.

Dietary Changes After Breast Cancer Diagnosis: Associations with Physical Activity, Anthropometry, and Health-related Quality of life Among Korean Breast Cancer Survivors: Sihan Song, Hyun Jo Youn, So Youn Jung, Eunsook Lee, Zisun Kim, Jihyoung Cho, Young Bum Yoo, Hyeong Gon Moon, Dong Young Noh, Jung Eun Lee; Korean J Community Nutr 2016;21(6):533-544. Published online December 31, 2016; DOI: https://doi.org/10.5720/kjcn.2016.21.6.533

Abstract PDF PubReader

OBJECTIVES
We aimed to examine levels of physical activity, anthropometric features, and health-related quality of life (HRQoL) among Korean breast cancer survivors who reported changes in their diet after diagnosis.
METHODS
A total of 380 women who had been diagnosed with stage I to III breast cancer and had breast cancer surgery at least six months before the interview were included. Participants provided information on dietary change after diagnosis, post-diagnostic diet, physical activity, anthropometric measures, and HRQoL through face-to-face interview. We assessed HRQoL levels of breast cancer survivors using a validated Korean version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and Breast Cancer Module (BR23). We used the logistic regression and generalized linear models to identify the associations of dietary changes in relation with physical activity, anthropometry, and HRQoL.
RESULTS
The majority of participants (72.6%) reported that they have changed their diet to a healthier diet after diagnosis. Breast cancer survivors who reported to have change to a healthy diet had higher intakes of vegetables and fruits and lower intakes of red and processed meats, and refined grains than those who did not. Also, survivors with a healthy change in their diet were more likely to engage in physical activity (top vs. bottom tertile: odds ratio [OR], 1.85; 95% confidence interval [95% CI], 1.02-3.36) and have lower body mass index (BMI) (OR, 0.90; 95% CI, 0.82-0.98 for one kg/mÂ² increment in BMI) compared to those who did not. We found that a healthy change in diet was associated with higher scores of physical functioning (p=0.02) and lower scores of constipation (p=0.04) and diarrhea (p=0.006) compared to those who did not.
CONCLUSIONS
Healthy changes in diet after breast cancer diagnosis may be associated with lower levels of BMI, and higher levels of physical activity and HRQoL.

Quality of Nutrient Adequacy and Health-related Quality of life of the Rural Elderly: Mee Sook Lee; Korean J Community Nutr 2015;20(6):423-432. Published online December 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.6.423

Abstract PDF PubReader

OBJECTIVES
In Korea, the percentage of elderly is increasing at an unprecedented rate, and is expected to account for 40% of the population by 2060. This massive demographic change stresses the importance of research on aging as it is necessary to improve the quality of life (QoL) of this population. This study aimed to examine the health-related quality of life (HRQoL) of the rural elderly and to clarify its association with the nutrient adequacy ratio (NAR).
METHODS
A cross-sectional study was performed in S-gun, Chonbuk, a critical agricultural area. The elderly people without abnormal physical functioning composed our study population and the data were collected by personal visits to 336 elderly people aged over 65 years (110 males and 226 females). Subjects were interviewed with questionnaires pertaining to general characteristics and EuroQol (EQ-5D). Nutrient intakes were assessed two days by 24-hours recall method. Subjects were defined as high QOL group if EQ-5D index with Nam's model was above the median.
RESULTS
Generally, EQ-5D index was lower in women than in man, and lower in older subjects than in younger subjects. The percentages of people below the median were 42% (low QoL group) and 58% (high QoL group) were found to be the above the median. The high QoL group had higher NAR, especially for vitamin C, vitamin B1, vitamin B2 and folate. All dimensions in the EQ-5D were affected by NAR of some nutrients and especially anxiety/depression dimension was significantly correlated with NAR of 5 nutrients (protein, calcium, iron, vitamin C and vitamin B1) and EQ-5D scores.
CONCLUSIONS
HRQol was significantly reduced in elderly with increasing age and this was more pronounced in women than in man. The NAR of some nutrients were associated with the EQ-5D index, especially anxiety/depression dimension, among rural elderly.

The Relationships among Quality of Life and Stress, Health-related Habits and Food Intake in Korean Healthy Adults Based on 2013 Korea National Health and Nutrition Examination Survey: Su Bin Lee, Hyun Jin Choi, Mi Joung Kim; Korean J Community Nutr 2015;20(6):411-422. Published online December 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.6.411

Abstract PDF PubReader

OBJECTIVES
This study investigated the socioeconomic factors that affect quality of life (QL) in healthy adults and to study the relationship between QL and health-related habits and food intake.
METHODS
Subjects consisted of 1,154 healthy adults without any known disease, aged 19 to 65 years from the 2013 Korean National Health and Nutrition Examination Survey data. We used SPSS statistical program version 20.0 for data analysis.
RESULTS
The average age and QL score of the study population were 36.7 years and 0.99 points, respectively. Males had a significantly higher QL score than the females (p < 0.001), and employed subjects and those employed in permanent positions had significantly higher scores as compared respectively with unemployed subjects and those employed in temporary positions (p < 0.001, p < 0.05). The group that responded "almost every day" to the "frequency of binge drinking" and "frequency of disruption of daily life due to drinking" had significantly lower QL scores as compared to other groups (p < 0.05). Further, the scores were significantly higher for individuals who practiced "intense physical activities" and "walking" (p < 0.001). The groups that responded that they were "very stressed" showed significantly lower QL scores in comparison to the other groups (p < 0.05). There were no significant differences in QL scores according to anthropometric or biochemical indices. When subjects were divided into two groups based on average QL scores, the frequency of intake of "barbecued beef" was significantly higher while the frequency of intake of "fried eggs or rolled omelet," and "soy milk" was significantly lower in the high QL group.
CONCLUSIONS
Based on these findings, it is evident that in healthy adults without any known underlying illnesses, psychological factors such as economic activity, occupational environment, and stress are considered to have a greater impact on their QL than are nutrient intake, blood biochemical indices, and anthropometric status.

Weight Control Behaviors, Health-related Quality of Life and Nutritional Status by Overestimation of Body Image among Young Korean Females: Data from the Fifth Korea National Health and Nutrition Examination Survey, 2010-2011: Seulki Park, Taisun Hyun, Hongmie Lee; Korean J Community Nutr 2015;20(5):362-374. Published online October 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.5.362

Abstract PDF PubReader

OBJECTIVES
This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females.
METHODS
A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group.
RESULTS
The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group.
CONCLUSIONS
The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

The Effect of Obesity-Related Quality of Life on selecting a Goal for Weight Management in Overweight and Obese Patients: Min Young Chun; Korean J Community Nutr 2015;20(4):281-290. Published online August 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.4.281

Abstract PDF PubReader

OBJECTIVES
Obesity is known to influence physical and mental health as well as the general quality of life. The aim of this study was to evaluate the effect of obesity related quality of life on selecting a goal for weight management in overweight and obese female patients.
METHODS
A total of 140 overweight or obese (Body mass index 23 kg/m2) female outpatients aged > or = 20 and < or = 60 years from one clinic participated in this study. Patients' desired weight (goal weight, ideal weight, satisfactory weight, acceptable weight and disappointed weight) and obesity related quality of life measures were evaluated. Univariate and multivariate analysis were performed to evaluate the effect of obesity related quality of life on goal weight reduction (%) and goal body mass index (BMI).
RESULTS
Mean BMI of overweight group, mild obesity group and severe obesity group were 62.0 +/- 4.8 kg, 68.5 +/- 5.5 kg and 83.5 +/- 9.6 kg, respectively. Mean weight loss expectations of the three groups were 16.4 +/- 4.7%, 19.5 +/- 5.3% and 30.2 +/- 6.8%, respectively and goal weight was significantly different among the three groups. Severe obesity group had a lower total quality of life score including physical, work-related, daily living domains than overweight or mild obesity groups. In univariate and multivariate regression analysis, psychosocial domain of quality of life had an effect on goal weight reduction (%) and goal BMI.
CONCLUSIONS
The results of this study demonstrated that the obese patients with poorer quality of life and psychosocial health tended to choose higher goal weight reduction and lower goal BMI.

The Association between the Adherence to Dietary Guidelines for Breast Cancer Survivors and Health-related Quality of Life among Korean Breast Cancer Survivors: Sihan Song, Jiyoung Youn, Myungsook Park, Eunkyung Hwang, Hyeong Gon Moon, Dong Young Noh, Jung Eun Lee; Korean J Community Nutr 2015;20(2):129-140. Published online April 30, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.2.129

Abstract PDF PubReader

OBJECTIVES
We examined the association between the adherence to dietary guidelines for breast cancer survivors and health-related quality of life in a cross-sectional study of Korean breast cancer survivors.
METHODS
A total of 157 women aged 21 to 79 years who had been diagnosed with stage I to III breast cancers according to the American Joint Committee on Cancer (AJCC) and had breast cancer surgery at least 6 months before the baseline were included. We used a Korean version of the Core 30 (C30) and Breast cancer 23 (BR23) module of the European Organization for Research and Treatment Cancer Quality of Life Questionnaire (EORTC-QLQ), both of which have been validated for Koreans. Participants were asked about their adherence to dietary guidelines for breast cancer survivors, suggested by the Korean breast cancer society, using a 5-point Likert scale. We summed dietary guideline adherence scores for each participant and calculated the least squares means of health-related quality of life according to dietary guideline adherence scores using the generalized linear model.
RESULTS
Breast cancer survivors who had higher adherence to dietary guidelines for breast cancer survivors had lower constipation scores than those with lower adherence (p for trend=0.01). When we stratified by the stage at diagnosis, this association was limited to those who had been diagnosed with stage II or III breast cancers. Also, sexual functioning scores increased significantly with increasing adherence scores of dietary guidelines among those with stage II or III breast cancers (p for trend < 0.001). However, among those who had been diagnosed with stage I, higher scores of dietary guidelines were associated with higher scores of pain (p for trend=0.03) and breast symptoms (p for trend=0.05).
CONCLUSIONS
Our study suggested that the health-related quality of life levels of breast cancer survivors are associated with the adherence to dietary guidelines and may differ by the stage of the breast cancer.

The Factors Influencing Health-Related Quality of Life in the Elderly: Focused on the General Characteristics, Health Habits, Mental Health, Chronic Diseases, and Nutrient Intake Status: Data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), 2010~2012: Hye Sang Lee; Korean J Community Nutr 2014;19(5):479-489. Published online October 31, 2014; DOI: https://doi.org/10.5720/kjcn.2014.19.5.479

Abstract PDF PubReader

OBJECTIVES
This study intended to determine significant factors that influence the health-related quality of life ("HRQoL"; EuroQol 5 Dimension health-related quality of life (EQ_5D) & EuroQol visual analogue scale (EQ_VAS)) of the elderly in Korea.
METHODS
This study was based on 3,903 subjects aged 65 years or more who participated in the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), 2010~2012. The HRQoL was analyzed by various factors (general characteristics, health habits, mental health, chronic diseases, nutrient intakes). SPSS statistics for complex samples (Windows ver. 21.0) was used.
RESULTS
The HRQoL was higher in the males, those with higher educational level or higher income level while it was lower in those belong to single households. In particular, the EQ_5D was significantly higher in the group who reported walking practice, moderate physical activity (male), and the group who reported no vigorous physical activity (female). The EQ_VAS was significantly higher in the group who reported walking practice. Both EQ_5D and EQ_VAS were significantly lower in the group with stress, melancholy, suicidal thinking, and osteoarthritis. EQ_5D was significantly lower in the group with < 75% Estimated Energy Requirements (EER) in energy intake, and with < Estimated Average Requirements (EAR) in iron or niacin intake. A stepwise regression analysis revealed that i) higher educational level (male), and good self-rated health status significantly increased the EQ_5D, ii) age, alcohol intake (male), melancholy (female), suicidal thinking, osteoarthritis, and niacin intake deficiency (male) significantly decreased the EQ_5D, iii) higher income level (male) and good self-rated health status significantly increased the EQ_VAS, and iv) age (male), stress, suicidal thinking (female) and osteoarthritis significantly decreased the EQ_VAS.
CONCLUSIONS
This study suggested that general characteristics, mental health, osteoarthritis, and niacin intake were associated with the HRQoL. Prospective research of long-term control is needed to establish the causal relationship between factors and the HRQoL.

Health-Related Factors Influencing the Quality of Life of Rural Elderly Subjects: Activities of Daily Living, Cognitive Functions, Prevalence of Chronic Diseases and Nutritional Assessment: Mee Sook Lee; Korean J Community Nutr 2012;17(6):772-781. Published online December 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.6.772

Abstract PDF PubReader

In order to supply the reference data to define the quality of life of the rural agricultural elderly population in the simplified steps, the data were collected by personal visits to 232 elder people over 65 (89 males and 143 females) in Sunchang area. The survey was conducted with written questionnaires concerning the quality of life, health-related habits, basic physical functions and cognitive behavior. The prevalence of the degenerative diseases were assessed by anthropometric and biochemical determinations. The averaged overall quality of life represented by EQ-5D index with Nam's model was calculated to be 0.865 +/- 0.1509, and the percentages of people below the average were 38% (low QOL group) and 62% (high QOL group) were found to be the above the average. Generally, the subjects with male gender, higher educational background, higher self-rated health status, higher social activities were belonged to the high QOL group. The high QOL group had higher scores of daily living activities KADL and IADL, and lower risks in cognitive functions K-MMSE and depression scale GDS. There was no statistically significant correlation between biochemical indexes of blood and cognitive function and EQ-5D scores when the results were adjusted for age and gender. There were significant differences in nutritional assessment determined by the MNA between the high and low QOL groups. The low QOL group showed inferior nutritional status. The rapidly measurable factors of the quality of life of rural elderly were turned out to be physical activity scores and the simplified nutritional status measurement.

Study on Diet-related Quality of Life in Online Self-help Diabetes Mellitus Patients Who Practice Dietary Regimen: Han Sul Lee, Jinhee Joo, Ryowon Choue; Korean J Community Nutr 2011;16(1):136-144. Published online February 28, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.1.136

Abstract PDF PubReader

Assessment of quality of life (QOL) is a new method to investigate the effectiveness of dietary regimen. Particularly, diet-related QOL is the most appropriate method to estimate social and psychological problems originated from dietary regimen practice. The purpose of this study was to evaluate the diet-related QOL and the correlation between diet-related QOL and health-related QOL, and dietary regimen practice in online diabetes self-help patients who practice the dietary regimen. Sixty one subjects who intended to practice dietary regimen were recruited from online diabetes self-help community, and instructed to fill-up the self report questionnaires. Contents of questionnaire were comprised of general characteristics, clinical characteristics, dietary compliance, and dietary regimen practice. As a result, the mean score of the 'Dietary impact' among the diet-related QOL sub-scales was the lowest suggesting most of the subjects suffer from burden of dietary regimen practice. The "Dietary impact" was correlated with "Taste", "Convenience" and "Cost" (p < 0.05). "Self-care" and "Satisfaction" were positively associated with well-controlled blood glucose and dietary regimen compliance, but negatively associated with "Dietary impact". Diet-related QOL was significantly correlated with the Health-related QOL, particularly the mental and social component (p < 0.05). Diet-related QOL was negatively associated with BMI, and self monitoring blood glucose was negatively correlated with "Self-care" (p < 0.05). In conclusion, Diet-related QOL might be appropriate to evaluate the effects of dietary regimen or nutrition education. The need for dietary education of cognitive-behavioral strategies and problem-solving ability is required.

A Study on the Prevalence of Chronic Diseases, Health-related Habits and Nutrients Intakes according to the Quality of Life in Korean Adults: Jee young Chung, Mi Young Lee, Mi Joung Kim; Korean J Community Nutr 2010;15(4):445-459. Published online August 31, 2010

Abstract PDF: This study was done to analyze the chronic diseases prevalence and dietary intake status according to the health related quality of life and to identify its significant properties. This study was conducted based on 2906 subjects ranging from 20~64 years old, out of 9704 total subjects from the 4th Korean National Health and Nutrition Survey in 2008. The average quality of life (QL) score was 0.915, where 983 subjects were below the average (low QL group) and 1923 subjects were above (high QL group). In the high QL group, there was more likely to be young, male, and with higher income and education. For high QL group, the self-related health score was high, and the subjective stress level was low. The prevalence of diabetes was significantly higher in the low QL group and anthropometric and biochemical measures were not shown differences between the two groups but waist circumference was significantly higher in the low QL group. The QL score was significantly negative correlated with the waist circumference and the body mass index. As for the recognition rate of Nutrition Guideline, there were no significant differences but high QL group had higher scores in "Eat a variety of foods", "Avoid too much Sodium", and "Enjoy meals and Eating a breakfast". Carbohydrate intake was significantly lower in the high QL group than in low QL group and the high QL group showed higher intake in legumes, meat and poultry, fruits, daily products and beverages. Overall results suggest that increased diabetes prevalence in people with low quality of life might be affected by the diets based on high carbohydrate, increased waist circumference, and lower rate of practice nutritional guideline.

An Assessment of Customer Satisfaction towards University Residence Hall Foodservice and Subjective QOL (Quality of Life): Focused on the University Students in Daegu, Gyeongbuk Area: Mi Kyung Choi, So Hee Choi, Songi Lee; Korean J Community Nutr 2009;14(1):114-122. Published online February 28, 2009

Abstract PDF: The purpose of this study was to identify the factors of university residence hall foodservice quality which has correlations with subjective QOL (quality of life) of target customers. A total of 176 questionnaires from students of 4 universities in Daegu, Gyeongbuk area were used for the analysis. The male students using residence hall foodservices were highly satisfied with 'clean appearances of employees' (4.86 +/- 1.25) and 'clean facilities' (4.79 +/- 1.26), while the degree of satisfaction with 'convenient facilities' (4.50 +/- 1.20) showed the highest score with female students. Ranking analysis using Spearman's rho revealed that there were significant correlations between students' satisfactions with the dimensions of 'foods and kindness of employees', 'hygiene', 'nutrition', and 'convenience' and their QOL, even though physical QOL of female students showed no significant correlation with satisfaction towards residence hall foodservices. As a conclusion, there should be efforts to improve the QOL of target customers through foodservice quality management.
