In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

Objectives: Decreasing muscle strength in old age has become a significant health problem because it increases the risk of falls or fractures and transfers to other diseases. The precise role of dietary protein intake in preventing or reducing muscle weakness is unclear. This study examined the relationship between handgrip strength and protein intake in Korean female elderly. Methods: This was a cross-sectional study that used data from the Seventh Korean National Health and Nutrition Examination Surveys (KNHANES) on female subjects aged 65 years and older. Low handgrip strength (LHGS) was defined as a handgrip strength below than 18 kg. Dietary intake data were obtained using the 1-day 24-hour recall method. Multiple regression was performed to test whether there is an independent relationship between the grip strength and protein intake, and the association between protein intake and LHGS was confirmed through multiple logistic regression. Results: The mean age of the 2,083 elderly females was 73.3 ± 0.1 years, and the prevalence of LHGS was 35% (n=734). Elderly women with an LHGS consumed less energy, total protein, and animal-based protein than those in the normal group. A multiple regression analysis after adjusting for covariate revealed a significant positive association between the handgrip strength and energy, protein, and animal-based protein intake. Multiple logistic regression analysis showed that the odds ratio (OR) of LHGS in female elderly with the highest quartiles of consumption of energy [OR, 0.65; 95% confidence interval (CI), 0.43-0.82; P for trend=0.004], and animal-based protein [OR, 0.59; CI, 0.40-0.87; P for trend=0.037] were significantly lower than those in the lowest quartiles. Conclusions: The energy intake and animal-based protein intake were negatively associated with the LHGS. These results suggest that adequate energy intake and protein intake, particularly those from animal-based sources, for elderly women in Korea are beneficial in lowering the risk of LHGS.

The purpose of this study was to evaluate nutrition intake and diet quality according to beverage consumption status in elementary school students (ESS = 317), middle-school students (MSS = 431), and high-school students (HSS = 373). We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into two groups, the non-beverage group and the beverage intake group according to beverage intake from drink types (fruit-vegetable drinks, carbonated drinks, and dairy drinks). Intake of dairy drinks was significantly lower in the carbonated drinks intake (CDI) group, compared with the non-CDI group in the MSS group. Intake of vitamin C was significantly higher in the fruit-vegetable drinks intake (FVDI) group, compared with the non-FVDI group. Intake of Ca and P was significantly lower in the CDI group, compared with the non-CDI group. Intake of vitamin B2, Ca, and P was significantly higher in the dairy drinks intake (DDI) group, compared with the non-DDI group. The mean adequacy ratio (MAR) of the FVDI group and the DDI group was significantly higher than those of the non-FVDI and non-DDI group. In diet quality, nutrients less than 1 on the index of nutritional quality (INQ) were significantly higher in the CDI group, compared with the non-CDI group. In conclusion, consumption of carbonated drinks dropped the diet quality however, consumption of fruit-vegetable drinks and dairy drinks improved the diet quality of micronutrients. Therefore, a well-planned diet must be used for replacement of nutrients lost from excessive intake of carbonated beverages during a time in life when growth is especially prominent.

Unmet healthcare needs are being used as an important indicator of the accessibility of healthcare services worldwide. To examine current status and trends of unmet needs in Korea, we used data from four sources: the Korea National Health and Nutrition Examination Survey (KNHANES, 2007-2017); the Community Health Survey (CHS 2008-2017); the Korea Health Panel Survey (KHP 2011-2015); and the Korean Welfare Panel Study (KOWEPS 2006-2017). The proportion of individual reporting unmet healthcare needs as of 2017 was 8.8% (KNHANES), 10.6% (CHS), and 12.4% (KHP as of 2015). The proportion of households reporting unmet healthcare needs due to cost was 0.5% (KOWEPS). Annual percentage change was -19.2%, -13.3%, -5.8%, and -13.3% respectively. Low income populations had more unmet healthcare needs than high income populations. However, unlike the last two studies, the main reason for unmet medical reasons was that there was no time regardless of income level.

Previous Korean total diet studies (KTDSs) have estimated dietary exposure to toxic chemicals based on 110-120 representative foods selected from over 500 foods appeared in the Korea National Health & Nutrition Examination Surveys (KNHANES), which would result in a possible underestimation. In order to find measures for a closer-to-real estimate of dietary exposure to heavy metals, this study examined the feasibility of mapping foods to the representative foods in the KTDS by comparing estimates. In mapping, those foods not analyzed in the 2009 KTDS (443 out of 559 foods appeared in the 2007 KNHANES) were mapped to the 114 representative foods used in the 2009 KTDS based on the closeness in regards to biological systematics and morphological similarity. Dietary exposures to total mercury and lead were re-estimated using the content of total mercury and lead in 114 foods analyzed in the 2009 KTDS, food intake, and individual's own body weight for respondents in the 2007 KNHANES instead of mean body weight of Koreans used in the 2009 KTDS. The re-estimates of exposure with mapping were approximately 50% higher than the original estimates reported in the 2009 KTDS. In addition, mapping enabled the comparison of percentile distribution of the exposure among populations of different age groups. In conclusion, estimates via mapping resulted in a more comprehensive estimation of dietary exposure to heavy metals present in foods that Koreans consume.
