Anthropometric Index, Dietary Habits and Nutrient Intake of the Oldest-old Population Aged 95 and Over Living in Seoul: Chung Shil Kwak, Ji Hyun Cho, Miyong Yon, Sang Chul Park; Korean J Community Nutr 2012;17(5):603-622. Published online October 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.5.603

The population aged 95 years and older in Seoul approximately increased to five-fold over the past 10 years, while nationwide rates increased to three-fold. In order to examine the dietary habit and nutritional status of oldest-old population living in Seoul, we recruited 87 subjects (25 males and 62 females) aged 95 years and older. The prevalence of underweight (BMI < 18.5 kg/m2) and obesity (BMI > or = 25 kg/m2) were 18.2% and 18.2% in males, and 20.8% and 9.4% in females, respectively. In self-assessment of health, only 25.3% answered to be unhealthy. More males exercised regularly and reported a wide range of activities than females. The average of %Kcal from carbohydrate, protein and fat (C : P : F) was 64.9 : 13.8 : 21.2 in males and 68.1 : 14.2 : 17.7 in females. The average daily energy intake was 1,307 kcal in males and 1,304 kcal in females. More than 75% of subjects were taking under estimated average requirements (EAR) for vitamin B1, B2 & C and Ca. The average of mean adequacy ratio (MAR) was 0.66 in males and 0.70 in females, and 28.8% of males and 12.9% of females were in MAR < 0.50. Based on MAR, 32.0% of males and 14.5% females were classified as normal and 16.0% of males and 25.8% of females were classified as malnourished. Our subjects were taking more animal food, especially milk and its products, compared to those living, in rural areas. However, a significant proportion did not meet the EAR for vitamin B1, B2 & C and Ca.

The Use of Iron Supplements of Pregnant Women and Pregnancy Outcome: Ji Hyun Cho, Hong Seok Ahn, Hyun Sook Bae; Korean J Community Nutr 2009;14(3):327-339. Published online June 30, 2009

Abstract PDF: It is known that Korean pregnant women take iron supplements at a higher than the recommended level. This study was designed to provide data on current iron intake levels both from food sources and supplement to better guide iron supplement use during pregnancy. We also explored associations of iron supplement intake levels with varioussociocultural factors and pregnancy outcomes. Dietary intakes of 510 pregnant women were assessed by a validated 102- item food frequency questionnaire, and information on types and amounts of nutritional supplement intakes were also attained. While dietary intake levels of most nutrients exceeded the KDRIs (Korea Dietary Reference Intakes: EAR: Estimated Average Requirements), folate fell short of the KDRIs. A total of 428 women (83.9%) reported to take iron supplement. The pregnant women were divided into the three groups (group I: Fe supplement intake < or = EAR, group II: EAR< Fe supplement intake < or = 3 times of EAR, group III: 3 times of EAR< Fe supplement intake). The mean dietary intake of iron was 24% of the total iron intake for pregnant women. Iron intake from food was not significantly different among I, II, and III. In case of iron intake from supplements, the most frequent dose (34.1%) was 90-100 mg/day, and the mean iron supplement intake was 362% of the EAR. The study findings showed that those with higher levels of iron supplements had better meal quality measured by NAR (Nutrient Adequacy Ratio) and INQ (Index of Nutrient Quality). In addition iron supplement intake levels were significantly related to age (20s: 66.5 +/- 38.6 mg/day, 30s: 77.3 +/- 47.8 mg/ day, p< 0.0116) and experience of childbirth (1st pregnancy: 70.9 +/- 41.2 mg/day, 2nd pregnancy: 64.5 +/- 39.5 mg/day, > or = 3rd pregnancy: 94.4 +/- 63.8 mg/day, p< 0.005). However, no significant difference was found between iron supplement intake levels and various pregnancy outcomes including birth weight, birth height, gestational age, weight gain during pregnancy, and jaundice. It is worrisome that iron intake by supplement use greatly exceeded the EAR, suggesting the need of appropriate guidelines for iron supplement intake during pregnancy. Thus iron overdose from supplements in pregnancy should be considered as a serious condition.
