이정우(Jung Woo Lee),김유경(Yookyung Kim) 한국가정과교육학회 2023 한국가정과교육학회지 Vol.35 No.2

본 연구는 코로나-19 유행기간 동안 한국 청소년들의 식생활 행태 변화를 분석해 보고자 하였다. 2018년부터 2021년까지 청소년 건강행태조사에 참여한 12-18세 227,139명의 설문자료를 사용하였다. 2018-2019년에 참여한 117,343명과 2020-2021년에 참여한 109,796명의 자료를 비교하였다. 다중 회귀 분석을 사용하여 2018-2019년을 기준으로 식생활 행태 변화를 공변량이 보정된 오즈비를(adjusted odds ratio, AOR) 계산하였다. 탄산음료를 전혀 섭취하지 않는 군과 1주일에 3번 이상 탄산음료를 섭취하는 군 사이의 오즈비를 비교했을 때, AOR 0.81(95% confidence interval [CI]: 0.78-0.84)로 코로나-19 유행기간 동안 유의하게 감소하였다(p<0.001). 마찬가지로, 단맛 음료를 전혀 섭취하지 않는 군과 1주일에 3번 이상 단맛 음료를 섭취하는 군 사이의 오즈비를 비교했을 때 AOR 0.69 (95% CI: 0.67-0.72)로 코로나-19 유행기간 동안 감소하였다(p<0.001). 반면, 1주에 3번 이상 패스트푸드를 섭취하는 AOR (1.15, 95% CI: 1.11-1.20)과 1주에 3번 이상 아침식사를 거르는 AOR (1.23, 95% CI: 1.20-1.26)은 코로나-19 유행기간 동안 유의하게 증가하였다. 과일 섭취량은 코로나-19 유행 동안 감소하였으며, AOR 1.26 (95% CI: 1.21-1.31)이었다. 결론적으로, 코로나-19 유행은 한국 청소년들의 식생활 행태에 긍정적인 영향과 부정적인 영향을 동시에 미쳤다. This study examined the changes of the dietary behaviors of Korean adolescents during the COVID-19 pandemic. Data were obtained from 227,139 students aged 12-18 who participated in the Korean Youth Risk Behavior Survey from 2018 to 2021. The participants were divided into two groups: 117,343 students from the 2018-2019 survey and 109,796 from the 2020-2021 survey. Multiple regression analyses were used to calculate the adjusted odds ratio (AOR) for dietary behavior changes between the two groups. The AOR for consuming carbonated beverages among those who consumed three or more times per week compared to those who did not consume carbonated beverages at all was 0.81 (95% confidence interval [CI]: 0.78-0.84), which significantly decreased during the COVID-19 pandemic (p<0.001). Similarly, the AOR for consuming sweetened beverages between those with three or more times and not at all per week was 0.69 (95% CI: 0.67-0.72) (p<0.001). In contrast, there was a significant increase in the AORs for consuming fast food (AOR: 1.15, 95% CI: 1.11-1.20) and skipping breakfast more than three times per week (AOR: 1.23, 95% CI: 1.20-1.26) during the same period. Fruit intake decreased during the COVID-19 pandemic (AOR: 1.26, 95% CI: 1.21-1.31). In conclusion, the COVID-19 pandemic had both positive and negative impacts on the dietary habits of Korean adolescents.

일부 암 환자들의 영양섭취 실태에 관한 조사 연구

문수재,정유경,윤정순 연세대학교 생활과학연구소 1992 生活科學論集 Vol.6 No.-

The purpose of this study was to investigate changes in life-style and nutritional status of outpatients who were clincally malnourished due to chemotheraphy. To estimate nutritional imbalance and problems, 88 patients (38 males, 50 females) were surveyed on nutrient intake before and after illness, their energy expenditure and usual behavior. The data were compiled and analyzed by the SPSS-PC program. When compared with the period before falling ill, all kinds of nutrient intake, including calorie and protein, decreased markedly during the anti-cancer therapy. In caloric consumption the mean ratio for carbohydrate: protein: fat before the malignancy was 47: 15: 19 and alcohol was 19%. Calorie and protein intake by subjects did not reach the recommended dietary allowances (RDA). Especially, a large number of the partients took less than 1,000 kcal in calorie. In both sexes, energy balance of most subjects appeared to be negative. That is, the calorie intake of 78.9% of the males and 78% of the females was less than their total energy expenditure per day. The results suggests that the patients should be supported with nutrients in order to tolerate anti-cancer therapy.

Association between plant protein intake and grip strength in Koreans aged 50 years or older: Korea National Health and Nutrition Examination Survey 2016–2018

Jun Sook-Hyun,Lee Jung Woo,Shin Woo-Kyoung,Lee Seung-Yeon,Kim Yookyung 한국영양학회 2023 Nutrition Research and Practice Vol.17 No.5

BACKGROUND/OBJECTIVES: We investigated the association of plant and animal protein intake with grip strength in Koreans aged ≥ 50 yrs. SUBJECTS/METHODS: The data was collected from 3,610 men and 4,691 women (≥ 50 yrs) from the 2016–2018 Korea National Health and Nutrition Examination Sur vey. We calculated the total energy intake, and the intake of animal and plant protein and collected dietar y data using 1-day 24-h dietar y recalls. Low grip strength (LGS) was defined as the lowest quintile (men: up to 26.8 kg, women: up to 15.7 kg). The association of protein intake with grip strength was examined using Pearson’s correlation and multiple linear regression analysis. RESULTS: The results proved that participants with LGS had lower daily energy, protein and fat intake, and percent energy from protein than those with normal or high grip strength (P < 0.0001). Total energy intake, animal protein, and plant protein were positively associated with grip strength. A higher intake of total plant protein (P for trend = 0.004 for men, 0.05 for women) and legumes, nuts, and seeds (LNS) protein (P for trend = 0.01 for men, 0.02 for women) was significantly associated with a lower prevalence of LGS. However, non-LNS plant protein intake was not associated with LGS (P for trend = 0.10 for men, 0.15 for women). In women, a higher total animal protein intake was significantly associated with decreased LGS (P for trend = 0.03). CONCLUSIONS: Higher total plant protein and LNS protein intake are negatively associated with LGS.

본 연구는 청년 1인가구를 위한 식생활교육 프로그램을 실시한 후, 교육 효과를 분석 및 평가하였다. 식생활교육 프로그램은성북구에 거주하는 청년 1인 가구를 대상으로 이론 강의와 실습을 포함한 4회의 대면수업과 1회의 온라인수업을 통해 5주동안(2020년 11월 10일부터 12월 8일까지) 진행되었다. 식생활교육 프로그램 효과는 한국영양학회가 제공하는 성인 영양지수(NQ) 설문지, 자체 개발된 식생활 평가점검표 설문지 및 포토보이스를 통해 분석하였다. 성인 영양지수(NQ) 분석 결과, 영양점수의 평균은 51.81점에서 53.20점으로 상승하였으나 통계적으로 유의미한 차이는 없었다. 그러나 4개의 하위영역 중 ‘절제’ 영역에서는 유의미한 변화가 나타났다(p<0.05). 자체 개발된 식생활 평가점검표 분석 결과, ‘중요도’ 영역 평균은 3.77점에서3.99점으로 상승하였으나, 통계적으로 유의미한 차이는 없었다. ‘실천도’ 영역 평균은 3.03점, 3.57점으로 상승하였으며, 통계적으로 유의미한 결과가 나타났다(p<0.05). 중요도의 설문 범주별 사전⋅사후 평균 비교분석 결과, 4개 영역에서, 실천도의 설문범주별 사전⋅사후 평균 비교분석 결과에서는 5개 모든 항목에서 유의미한 결과가 나타났다(p<0.05). 총 200장의 포토보이스를사회인지이론에 근거하여 분석한 결과, 사람들이 건강한 집에서 만든 음식을 먹는 데 도움이 되는 결정요인은 환경적 요인48%, 행동적 요인 30%, 개인의 인지적 요인 22%로 나타났다. 반면, 참가자들이 집에서 만든 건강한 음식을 먹는 것을 방해하는결정요인은 환경적 요인 72%, 개인의 인지적 요인 14%, 행동적 요인이 14%로 나타났다. 이러한 결과에 대한 종합적인 분석은청년 1인 가구를 위한 식생활교육 프로그램이 동기 부여를 촉진하고, 행동 변화를 촉진하고, 주변 환경을 개선하는 효과적인도구가 될 수 있음을 시사한다. This study analyzed and verified the effects of a dietary education program for Korean young adults in single-person households. The dietary education program was conducted for five weeks (from November 10 to December 8, 2020) for Korean young adults in single-person households living in Seongbuk-gu, via four face-to-face education sessions and one online education session, including both theoretical lectures and practice. The effect of the dietary education program was analyzed through the Nutrition Quotient (NQ) questionnaire for adults provided by the Korean Nutrition Society, a dietary evaluation checklist questionnaire developed by the researchers, and photovoices. The average of ‘Nutrition’ score increased from 51.81 to 53.20, but there was no statistically significant difference. However, there was a significant change in the ‘Moderation’ category (p<0.05). As for the researcher-developed dietary evaluation, the average of the ‘Importance’ area rose from 3.77 to 3.99, but there was no statistically significant difference. The average of the ‘Practice’ area rose from 3.03 to 3.57, significant results were found (p<0.05). When the pre-/post-tests were compared by the sub-categories, four elements of ‘Importance’, i.e., balanced meals and avoided foods, and all five elements of ‘Practice’ were significantly improved (p<0.05). A total of 200 photovoices were analyzed according to Social Cognitive Theory. As a result of the analysis, the deterrents that help people eat healthy homemade food were 48% environmental factors, 30% behavioral factors, and 22% individual cognitive factors. The deterrents found to hinder participants from eating healthy homemade food were 72% environmental factors and 14% individual cognitive and behavioral factors. The results suggest that the dietary education program for Korean young adults in single-person households can be an effective tool that promotes self-motivation, behavioral changes, and improvements of the surrounding environment.
