Cost-benefit Analysis of Nutrition Management Program for Children Aged Under 5 Years in DR Congo: Tae Ho Lee, Chae Eun Lee, Eun Woo Nam; Korean J Community Nutr 2018;23(5):385-396. Published online October 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.5.385

Abstract PDF PubReader: OBJECTIVES
This study aims to evaluate the economic efficiency of a nutrition management program for children under 5 years of age in Kenge, Kwango District, Democratic Republic of the Congo (DR Congo) from 2014 to 2016.
METHODS
The economic efficiency of a nutrition management program for children under 5 years of age who have recovered from malnutrition status was evaluated using a cost-benefit analysis. The costs were analyzed according to the executed budget incurred during the project period. The benefits were estimated as the monetary value of the saved lives of children under 5 years of age. The economic efficiency of the program was determined by the Benefit-Cost Ratio (BCR). The BCR was calculated by dividing the total discounted benefit by the total discounted costs. The project is economically efficient when the BCR is greater than 1.
RESULTS
The costs of the nutrition management program were calculated as 1,677,609,648 Korean Won (KRW). A total of 2,466 children survived with improved malnutrition status through this program. The benefit for the reduction of mortality for children under 5 years of age was estimated to be 6,814,354,467 KRW, the estimated value of life for 2,466 children. The BCR was 4.06.
CONCLUSIONS
The nutrition management program for children under 5 years of age in DR Congo was found to be a cost-effective project. Successful and efficient Official Development Assistance (ODA) for a health project requires integrated and comprehensive strategies and specialized international development consulting to improve efficiency. Future nutrition management programs should take into account the national health program to maintain the sustainability of the project.

Cost-benefit Analysis of Sodium Intake Reduction Policy in Korea: Chulhee Lee, Dae Il Kim, Jeonglim Hong, Eunmi Koh, Baeg Won Kang, Jong Wook Kim, Hye Kyung Park, Cho Il Kim; Korean J Community Nutr 2012;17(3):341-352. Published online June 30, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.3.341

It is well established that excessive sodium intake is related to a higher incidence of chronic diseases such as hypertension, stroke, coronary heart disease, cardiovascular disease and gastric cancer. Although the upper limit of the current sodium intake guideline by WHO is set at 2,000 mg/day for adults, sodium intake of Koreans is well over 4,700 mg/capita/day implying an urgent need to develop and implement sodium intake reduction policy at the national level. This study investigated the cost-effectiveness of the sodium intake reduction policy, for the first time, in Korea. Analyses were performed using most recent and representative data on national health insurance statistics, healthcare utilization, employment information, disease morbidity/mortality, etc. The socioeconomic benefits of the policy, resulting from reduced morbidity of those relevant diseases, included lower medical expenditures, transportation costs, caregiver cost for inpatients and income losses. The socioeconomic benefits from diminished mortality included reductions in earning losses and welfare losses caused by early deaths. It is estimated that the amount of total benefits of reducing sodium intake from 4.7 g to 3.0 g is 12.6 trillion Korean Won; and the size of its cost is 149 billion Won. Assuming that the effect of sodium intake reduction would become gradually evident over a 5-year period, the implied rate of average return to the sodium reduction policy is 7,790% for the following 25 years, suggesting a very high cost-effectiveness. Accordingly, development and implementation of a mid-to-long term plan for a consistent sodium intake reduction policy is extremely beneficial and well warranted.

A Study of Hospital Foodservice Satisfaction after Covering Hospital Foodservice in the National Health Insurance: Rah Il Hwang, Jin Hee Kwon; Korean J Community Nutr 2008;13(3):396-404. Published online June 30, 2008

Abstract PDF: This study aimed to evaluate the amount of patients' satisfaction with hospital foodservices among those who were benefited from national health insurance during theirhospitalization. A total of 3,094 inpatients from 191 medical institutions were enrolled in this survey. The survey was carried out from July 23 to September 14, 2007 through the face-to-face interview method. All analyses were made using the SPSS software (version 13.0). The mean age of the participants was 53.3 years, 57.0% were women; 34.7% were high-school graduates. Among the respondents, 30.9% stayed in the hospital for 7~14 days long, and 52.0% were hospitalized in multi-patient rooms for six persons. The 87.7% of total population had a general diet, and 9.6% selected the food menu that was notcovered by health insurance. In addition, 38.3% of patients regarded the fee of foodservice as inexpensive. Overall, the satisfaction score with hospital foodservice was 3.63 on a Likert-type scale ranging from 1 (extremely dissatisfied) to 5 (extremely satisfied). However, the limitations were indicated including the lack of providing nutritional information and quality of taste. In conclusion, the quality of hospital foodservice might not deteriorate even after enforcement of national payment of medical insurance. Further efforts are required for the diversification of menus and legislative work for improving quality of food service for a successful hospital foodservice policy.

A Study of Hospital Foodservice Management after Covering Hospital Foodservice in The National Health Insurance: Rah Il Hwang, Jin Hee Kwon, Hyun Jin Jeong, Jung Hee Kim, Ho Young Lee; Korean J Community Nutr 2008;13(2):244-252. Published online April 30, 2008

Abstract PDF: The purpose of this study is to investigate the overall operations of National Hospital Food service after it was benefited by National Health Insurance (NHI). The survey was conducted between July and August, 2007. Among questionnaires mailed to 2,558 medical care institutions, 2,090 returned (81%) questionnaires were analyzed by descriptive statistics, chi-square -test and ANOVA using the SPSS 13.0. The general foodservice characteristic of medical care institutions were as follows. The type of foodservice operations were 'self-operated' (86.9%), 'contracted' (10.5%) and 'Both' (2.6%). Only 6.4% of medical care institutions provided 'hospital food menu not benefited by NHI'. The number of dietitians and cook for medical care institutions were 1.1 and 1.0, respectively. The cost of a general diet meal was 4,205 won and therapeutic diet meal was 4,434 won. The overall operations of hospital foodservice were different depending on the types of medical care institution. After hospital foodservice was benefited by NHI, the overall quality of hospital foodservice including manpower, facilities, and environment was improved. The future direction of hospital foodservice should 1) differentiate the cost of hospital foodservice by the types of medical care institution, 2) increase in co-payment, and 3) provide same service with equal expenses in each party as medical aid or NHS beneficiary.

Relationships among Personality Preferences, Psychosocial Factors and Dietary Habits of Middle School Students: Hye Sung Kim, Hye Young P Kim; Korean J Community Nutr 2007;12(5):511-518. Published online October 31, 2007

Abstract PDF: The purpose of this study was to obtain an understanding of the association of personality preferences and food behavior factors in middle school students. The subjects were 319 boys and girls in a middle school located in Kyunggi province. A self-administered questionnaire was used to assess demographic factors, dietary habits and psychosocial factors including self-efficacy, perceived benefits and barriers. The MMTIC (Murphy-Meisgeier Type Inventory for Children) test was used to assess the personality preferences of the students. Sixty-seven percent of the subjects were extrovert, 53.9% were the sensing type, 76.8% were the feeling type and 81.8% were the perceiving type in personality preferences. The extrovert had higher self-efficacy than the introvert. The feeling type perceived more benefits and fewer barriers than the thinking type. The education levels of the parents, especially mothers, were positively related with self-efficacy and dietary habit scores of the students. The self-efficacy and perceived benefits and barriers were significantly associated with dietary habits of the students (explained variance: 17.9%). Results of this study presented the relationship of character types and parents' education levels on psychosocial food behavior factors and a need for the development of tailored nutrition education program considering these factors.

The Economic Benefits of Breastfeeding: Taisun Hyun, Ki Nam Kim, Nammi Kang, Eun Young Lim; Korean J Community Nutr 2002;7(6):863-871. Published online December 31, 2002

Abstract PDF: To compare the costs incurred by infant feeding between mothers who breastfed their infants and those who fed them infant formula, a questionnaire survey was carried out to 136 mothers living in Seoul, Cheongju and Chungju who breastfed and 199 mothers who formula-fed their infants. The cost of formula-feeding was estimated based on the expenditures for formula and feeding apparatus, and the time needed to wash bottles and prepare formula. The cost of breastfeeding was estimated based on the expenditures for food for the additional nutritional intake of these mothers. The mean cost of formula-feeding was 1,870,125won during the first year of the baby's life. The food cost for the additional nutritional intake of the breastfeeding mothers was 203,004 won per year. The extra medical cost for respiratory illnesses in the formula-fed group compared to the breastfed group was 62,920 won because the formula-fed infants required medical attention for respiratory illnesses more often than the breast-fed infants. Therefore, breastfeeding could save 1,730,041 won during the first year of an infant's life. We may have underestimated the cost savings from breastfeeding because we did not take into account the potentially decreased costs of fertility control and the health benefits for mothers, as well as the decreased usage of water and gas. Analyses showed that breastfeeding is not only nutritionally advantageous, but also economically advantageous for families and society.
