ABSTRACT

ABSTRACT Objective: The objective was to evaluate the efficacy of gabapentin in the management of neuropathic pain in patients with keratoconus, who were treated with fast (10 minutes) epi-off corneal crosslinking (CXL). Methods: This was a prospective, double-blind, randomized study. The sample comprised patients with bilateral progressive keratoconus, aged 12 years or older, who underwent a bilateral epi-off corneal CXL (fast - 10 minutes) procedure. One group was given placebo orally, and the other group received gabapentin 600 mg orally, both preoperatively. The visual analogue scale (VAS) was applied to record postoperative pain up to 48 hours after procedure. The study was conducted at the Belotto Stock Centro Oftalmológico, in the city of Joaçaba, Santa Catarina, Brazil, from June 2018 to September 2019. Results: At no point in the study significant differences were observed between groups, in terms of pain intensity measured by means of the VAS questionnaire, or of opioid use (Paco®), though opioid consumption was 21% lower in the group receiving gabapentin. Conclusion: We concluded gabapentin has no efficacy in postoperative pain control after epi-off corneal CXL (fast - 10 minutes). Although there was no statistically significant difference, the group that received gabapentin suffered less pain, resulting in lower opioid consumption. UTN number: U1111-1256-0330.


RESUMO Objetivo: Avaliar a eficácia do uso da gabapentina no manejo da dor neuropática em pacientes portadores de ceratocone submetidos ao tratamento de crosslinking corneano epi-off fast de 10 minutos. Métodos: Tratou-se de pesquisa prospectiva, duplo-cega, randomizada. A amostra foi composta de pacientes com ceratocone progressivo bilateral, a partir dos 12 anos de idade, submetidos ao procedimento de crosslinking corneano acelerado epi-off fast de 10 minutos bilateral. Um grupo recebeu placebo via oral e o outro, gabapentina 600mg, via oral, ambos no pré-operatório. A Escala Visual Analógica foi aplicada para registrar a dor pós-operatória até 48 horas após o procedimento. A pesquisa foi realizada no período de junho de 2018 a setembro de 2019 em um centro oftalmológico. Resultados: Não foram observadas diferenças estatísticas significativas para ambos os grupos, tanto na intensidade da dor medida pela Escala Visual Analógica, como na redução do uso do opioide (Paco®), em qualquer horário analisado durante um período de 48 horas. No entanto, houve redução de 21% no consumo de opioides pelo grupo que fez uso da gabapentina. Conclusão: A gabapentina não demonstrou eficácia no controle da dor no pós-operatório do crosslinking corneano epi-off fast de 10 minutos. No entanto, observou-se que, mesmo não havendo diferença estatisticamente significativa, houve diminuição da dor no grupo em que foi usada a gabapentina, resultando na redução do consumo de opioides. Número UTN: U1111-1256-0330.

ABSTRACT

ABSTRACT Purpose: This study was performed to evaluate the outcomes of accelerated corneal cross-linking in keratoconic corneas with thinnest pachymetry values of <400 µm. Methods: The study included 28 eyes of 24 patients. The uncorrected and best-corrected visual acuities (logMAR), flattest and steepest keratometric readings, central corneal thickness at the thinnest point, corneal higher-order aberrations, and contrast sensitivity were assessed before and at 1, 3, 6, 12, and 24 months after corneal cross-linking. Result: The mean best-corrected visual acuity and contrast sensitivity increased (p=0.02, p=0.03, respectively), whereas the mean uncorrected visual acuity did not significantly differ (p>0.05) at 24 months after corneal cross-linking, compared with measurements before corneal cross-linking. Although the mean flattest keratometric reading showed no significant change (p=0.58), the mean steepest keratometric reading was reduced when compared with its value before corneal cross-linking (p=0.001). No change was observed in the mean central corneal thickness at the thinnest point at 24 months after corneal cross-linking, compared with its value before corneal cross-linking (p=0.12). Conclusion: Accelerated corneal cross-linking in keratoconic eyes with thin corneas could halt the progression of keratoconus in corneas thinner than 400 µm at 24 months after treatment.


RESUMO Objetivo: Este estudo foi realizado para avaliar os resultados do cross-linking corneano acelerado em córneas ceratocônicas com os valores mais baixos de paquimetria <400 µm. Métodos: O estudo incluiu 28 olhos de 24 pacientes. As acuidades visuais não corrigidas e melhor corrigidas (logMAR), leituras ceratométricas mais planas e íngremes, espessura corneana central no ponto mais fino, aberrações corneanas de mais alta ordem e a sensibilidade ao contraste foram avaliadas antes e em 1, 3, 6, 12 e 24 meses após a realização do do cross-linking. Resultados: A média da acuidade visual melhor corrigida e a sensibilidade ao contraste aumentaram (p=0,02, p=0,03, respectivamente), enquanto a média da acuidade visual não corrigida não diferiu significativamente (p>0,05) aos 24 meses após o cross-linking, comparada com medidas antes do procedimento. Embora a leitura da média da ceratometria mais plana não tenha apresentado alteração significativa (p=0,58), a leitura ceratométrica mais íngreme diminuiu quando comparada ao seu valor antes do cross-linking (p=0,001). Não foi observada alteração na média da espessura corneana central no ponto mais fino aos 24 meses após o cross-linking em comparação com seu valor antes do procedimento (p=0,12). Conclusão: O cross-linking corneano acelerado nos olhos ceratocônicos com córneas finas pode interromper a progressão do ceratocone nas córneas mais finas que 400 µm 24 meses após o tratamento.

ABSTRACT

PURPOSE: This study assessed the food intake and nutritional status of the elderly in long-term care facilities in order to provide adequate food services and improve the nutritional status.METHODS: The survey was carried out from August 2019 to October 2019 for the elderly in long-term care facilities located in Gwangju Metropolitan City. The survey was conducted to collect data from 199 elderly persons (34 males and 165 females) aged over 65 years old. The food intake was assessed using a 1-day 24-hour recall method.RESULTS: More than 90% of the subjects were over 75 years old. Forty five percent of the subjects were active, 44.2% of the subjects perceived themselves as not being healthy. Dementia and Parkinson's disease were the most common diseases, followed by hypertension, musculo-skeletal disease, diabetes, and stroke. Only 25.6% of the subjects had most of their teeth intact, and 44.7% of the subjects had difficulty in chewing and swallowing. The total food intake was 1,127 g in males and 1,078 g in females. The most frequently consumed foods were kimchi, cooked rice with multi-grains, soybean soup, cooked rice with white rice, yogurt, pumpkin porridge, soy milk, and duck soup. The average energy intake of the subjects was 1,564.9 kcal in males and 1,535.5 kcal in females. The overall nutritional status of the elderly in the long-term care facilities was poor. In particular, the intake of vitamin D and calcium, vitamin C, riboflavin, and potassium were very low. The intake of vitamin D was 5 µg, and 86.4% of the elderly were below the estimated average requirement, while the intake of sodium was high.CONCLUSION: The results of this study can be used to understand the health and nutritional status and to improve the food services and nutrition management for the elderly in long-term care facilities.

ABSTRACT

PURPOSE: This study evaluated the dietary quality and nutritional status of elderly people using the Nutrition Quotient for Elderly (NQ-E).METHODS: The participants were 204 elderly people over 65 years of age (38 men and, 166 women) in Seoul. The dietary information was analyzed using a questionnaire of NQ-E, which consisted of 19 checklist items, and 24-recall test data. The NQ-E scores and its four factors, including ‘balance’, ‘moderation’, ‘diversity’, and ‘dietary behavior’ factors, were calculated according to general characteristics of the subjects. The subjects were divided into the ‘monitoring needed group’ (62 > NQ-E score) and the ‘good group’ (62 ≤ NQ-E score) according to their NQ-E score.RESULTS: The mean NQ-E score of the total subjects was 61.9, which was within the medium-high grade. The scores of balance, moderation, and dietary behavior factors were within the medium-high grade, while the score of the diversity factor was within the medium-low grade. The NQ-E score was 54.8 in the monitoring needed group and 69.3 in the good group. For the score of the diversity factor, the elderly living alone had a significantly lower score than the score for the elderly living with a spouse. The female subjects showed significantly higher scores of moderation and dietary behavior factors than did the male subjects. The daily intakes of vitamin A, thiamin, riboflavin, vitamin C and calcium in the monitoring needed group were significantly lower than those in the good group. The nutrient adequacy ratios (NAR) of vitamin A, thiamin, riboflavin, vitamin C and calcium in the monitoring needed group were significantly lower compared to the scores of the good group. The indexes of nutritional quality (INQ) of vitamin A, thiamin, riboflavin, vitamin C, calcium and potassium were less than 1 for all the subjects. The monitoring needed group had a significantly lower consumption of total foods, vegetables and mushrooms than the good group. As a result, the nutritional status of the monitoring needed group was significantly lower than that of the good group.CONCLUSION: The results of this study show that NQ-E would be a useful tool for assessing the dietary quality of the elderly. In conclusion, a focused-nutrition education program and a useful guideline are needed for promoting the health and nutritional status in elderly people.

ABSTRACT

Resumo Objetivo: Avaliar os resultados clínicos do Crosslinking Transepitelial (CXL) analisando sua eficácia em pacientes portadores de ceratocone progressivo. Métodos: Estudo transversal retrospectivo com 49 olhos e 37 pacientes com idades entre 10 e 50 anos, submetidos à técnica de CXL em 2017 no Instituto Panamericano da Visão, em Goiânia, Goiás, Brasil. Foi utilizado o sistema KXL Avedro programado no modo pulsado com intervalo (1/1 segundo), usando 45 mW/cm² com 7,2 J e solução de riboflavina a 0,25% da Avedro com córneas irradiadas por 8 minutos. Foram coletados os dados: sexo, idade, acuidade visual sem correção (AVSC), acuidade visual com correção (AVCC), astigmatismo, paquimetria no ponto mais fino e astigmatismo ceratométrico no pré-operatório e pós-operatório com 1, 6 e 12 meses. Foram utilizados os testes Kolmogorov-Smirnov, Qui-quadrado de Pearson, Friedman, Dunnett à posteriori e a correlação de Spearman. Resultados: Vinte e três pacientes (62,2%) eram do sexo feminino e 14 (37,8%) do sexo masculino. A média de idade foi de 27,89 (±10,89) anos. A AVSC e AVCC melhoraram significativamente no pré-operatório em relação a 1 mês (p=0,01) e (p<0,001), 6 meses (p<0,001 ambas) e 12 meses (p<0.001 ambas). O astigmatismo reduziu significativamente no pré-operatório em relação a 6 meses (p=0,02) e 12 meses (p=0,02). A paquimetria no ponto mais fino manteve-se constante no período (p=0,95). A diferença entre k2 e k1 (astigmatismo ceratométrico) mostrou redução significativa no pré-operatório em relação a 1 mês (p=0,01). Conclusão: A técnica de CXL foi segura e eficaz no tratamento e estagnação da doença em pacientes com ceratocone progressivo.


Abstract Objective: To evaluate the clinical results of Transepithelial Crosslinking (CXL) by analyzing its efficacy in patients with progressive keratoconus. Methods: Retrospective cross-sectional study with 49 eyes and 37 patients aged 10 to 50 years submitted to the CXL technique in 2017 at the Instituto Panamericano da Visão, in Goiânia, Goiás, Brazil. The Avedro KXL system was programmed in pulsed mode with interval (1/1 second), using 45 mW/cm² with 7.2 J and 0.25% riboflavin solution of Avedro with irradiated corneas for 8 minutes. Data were collected: sex, age, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), astigmatism, pachymetry at the thinnest point and keratometric astigmatism in the preoperative and postoperative periods at 1, 6 and 12 months. The Kolmogorov-Smirnov, Pearson's Chi-square, Friedman, Dunnett, and the Spearman correlation were used. Results: Twenty-three patients (62.2%) were female and 14 (37.8%) male. The mean age was 27.89 ± 10.89 years. The UDVA and CDVA significantly improved in the preoperative period in relation to 1 month (p = 0.01) and (p <0.001), 6 months (p <0.001 both) and 12 months (p <0.001 both). Astigmatism significantly reduced preoperatively in relation to 6 months (p = 0.02) and 12 months (p = 0.02). The pachymetry at the thinnest point remained constant in the period (p = 0.95). The difference between k2 and k1 (keratometric astigmatism) showed a significant reduction in the preoperative period in relation to 1 month (p = 0.01). Conclusion: The CXL technique was safe and effective in the treatment and stagnation of the disease in patients with progressive keratoconus.

ABSTRACT

ABSTRACT Purpose: To report our initial experience in the treatment of Acanthamoeba keratitis with accelerated corneal collagen cross-linking. Methods: Retrospective chart review of patients diagnosed with Acanthamoeba keratitis with progressive corneal melting who were treated with accelerated collagen cross-linking. Results: A total of 6 eyes (5 patients) were reviewed. All the patients received adjuvant therapy with moxifloxacin and chlorhexidine. In 4 cases, the ulcer healed with a mean interval to epithelialization of 108.8 days (range 59-217). In 2 eyes, there was a persistent neurotrophic ulcer. The melting was not progressive in any case, nor did any eye required emergency penetrating keratoplasy. Conclusion: This study suggests a beneficial effect of accelerated collagen cross-linking in cases of Acanthamoeba keratitis with corneal melting. Thus, collagen cross-linking may be considered as adjuvant treatment for Acanthamoeba keratitis.


RESUMO Objetivo: Relatar nossa experiência inicial no tra tamento da ceratite por Acanthamoeba com reticulação acelerada de colágeno corneano. Métodos: Revisão retrospectiva de prontuários de pacientes diagnosticados com ceratite por Acanthamoeba, com deformação progressiva da córnea, tratados com reticulação acelerada de colágeno. Resultados: Seis olhos (5 pacientes) foram incluídos. Todos os pacientes receberam terapia adjuvante com moxifloxacina e clorexidina. Em 4 casos, a úlcera cicatrizou com uma média de epitelização de 108,8 dias (amplitude de 59-217 dias). Em dois pacientes, a úlcera apresentou um comportamento neurotrófico. A deformação não foi progressiva em nenhum dos pacientes e nenhum dos olhos exigiu ceratoplastia penetrante de emergência. Conclusão: Este estudo sugeriu um efeito benéfico da reticulação acelerada de colágeno em casos de ceratite por Acanthamoeba infecciosa com deformação corneal. A reticulação de colágeno parece ser uma alternativa coadjuvante possível para casos de ceratite por Acanthamoeba.

ABSTRACT

ABSTRACT Purpose: To evaluate the effect of accelerated corneal crosslinking on corneal biomechanics with an ocular response analyzer in patients with progressive keratoconus. Methods: In this retrospective study, 50 eyes of 45 patients with progressive keratoconus who underwent accelerated corneal crosslinking were evaluated with ocular response analyzer waveform parameters before and one year after corneal crosslinking. Paired two-tailed Student's t-test was performed to compare the parameters before vs. after corneal crosslinking. Results: Mean patient age was 17.6 ± 3.6 (range 9-25) years. A significant increase was observed in p1 area, p2 area, h2, and dive2 values. No significant difference in corneal hysteresis, corneal resistance factor, or other waveform-derived parameters was observed at one year postoperatively. Conclusion: For estimating the effect of accelerated corneal crosslinking on corneal biomechanics, parameters such as p1 area, p2 area, h2, and dive2 are more sensitive than corneal hysteresis and corneal resistance factor. These results may help us to find out which corneal crosslinking method is most effective for stiffening the cornea.


RESUMO Objetivo: Avaliar o efeito do cross-linking corneano acelerado na biomecânica corneana com analisador de resposta ocular em pacientes com ceratocone progressivo. Métodos: Neste estudo retrospectivo, 50 olhos de 45 pacientes com ceratocone progressivo submetidos à cross-linking corneano acelerado foram avaliados com os parâmetros da forma de onda do analisador de resposta ocular antes e um ano após o tratamento com cross-linking corneano. O teste t de Student pareado bicaudal foi realizado para comparar os parâmetros antes e depois do cross-linking corneano. Resultados: A média de idade dos pacientes foi de 17,6 ± 3,6 (variação de 9 a 25) anos. Um aumento significativo foi observado nos valores de p1area, p2area, h2 e dive2. Nenhuma diferença significativa foi encontrada na histerese da córnea, fator de resistência da córnea ou outros parâmetros derivados da forma de onda foi observada em um ano de pós-operatório. Conclusão: Para estimar o efeito do cross-linking corneano acelerado na biomecânica corneana, parâmentros como p1area, p2area, h2 e dive2 são mais sensíveis que histerese da córnea e fator de resistência corneana. Esses resultados podem nos ajudar a descobrir qual método cross-linking corneano é mais eficaz no enrijecimento da córnea.

ABSTRACT

BACKGROUND/OBJECTIVES: The aim of this study was to analyze the factors related to sarcopenic obesity among the elderly in South Korea. SUBJECTS/METHODS: A total of 3,367 elderly (≥ 65 years) from the Korea National Health and Nutrition Examination Survey (2008–2011) were included in this analysis. The subjects were assessed to determine their sarcopenia and obesity status. Sarcopenia was assessed by determining their appendicular skeletal muscle mass (ASM). Obesity was defined by the waist circumference. An association of sarcopenic obesity and the related factors was analyzed using multiple logistic regression models. RESULTS: The risk of sarcopenic obesity of the subjects was decreased by active physical activity. After adjusting for age, smoking, and alcohol consumption, the risk of sarcopenic obesity in men of the highest level group (Q4) decreased by 45% (OR = 0.550, 95% CI = 0.334–0.905, P trend 0.018) compared to that in the reference group (Q1). Among the women, the risk of sarcopenic obesity in the Q3 and Q4 groups decreased by 29.0% (OR = 0.710, 95% CI = 0.512–0,984) and 56.7% (OR = 0.433, 95% CI = 0.281–0.668), respectively, compared to that in the Q1 group (P trend < 0.001). The mean daily energy intake was higher in the non-sarcopenia group than in the sarcopenia group. The risk of sarcopenic obesity in subjects not meeting the recommended intakes of energy, riboflavin, and vitamin C increased significantly by 25.4%, and 36.6%, and 32.6%, respectively, compared to that in the subjects meeting the recommended nutrient intake. CONCLUSION: Active physical activity as well as an adequate intake of energy and some vitamins might be negatively associated with the development of sarcopenia and sarcopenic obesity in the elderly.

ABSTRACT

OBJECTIVES: The purpose of this study was to investigate the food, nutrient intake, and diet quality of postmenopausal women at high risk of osteoporosis (OP) and cardiovascular disease (CVD) compared with those of control subjects. METHODS: A total of 1,131 post-menopausal women aged over 45 years, who took the 2010–2011 Korean National Health and Nutrition Examination Survey (KNHANES), were included for analysis. These participants were classified into the following groups: the OP group, with a risk of OP (n=135); the CVD group, with a risk of CVD (n=373); the OP+CVD group, with a risk of OP and CVD concurrently (n=218); and the control group (n=405) according to bone mineral density (BMD) and CVD risk. Anthropometric measurements, blood profiles, dietary intake, and dietary quality indices were measured and compared among the four groups. RESULTS: Waist circumference, total body fat percentage, blood pressure, fasting plasma glucose, total cholesterol, triglyceride, and LDL-cholesterol were higher, and HDL-cholesterol and BMD were lower in the OP+CVD group than in the control group. In the food frequency questionnaire, the OP+CVD group had significantly higher frequencies of grain (except for multi-grain) and lower frequencies of fruit and dairy product. The frequency of consumption of red meat, processed meat, and carbonated beverages was higher in OP+CVD group. In nutrient density analysis, proteins and vitamin B2 levels were significantly lower in the OP+CVD group than in the control group. The nutritional quality index (INQ) values of calcium were in the order of 0.63, 0.58, 0.56, and 0.55 in each group, and it was urgent to improve the dietary intake for calcium in postmenopausal women. In addition, vitamin B2 was inadequately consumed by all groups. CONCLUSIONS: These results suggest that it is necessary to increase the intake of vitamin B2 and calcium and decrease the frequency of intake of red meat, processed meat, and carbonated beverages in postmenopausal women with the risk of OP and CVD.

ABSTRACT

BACKGROUND/AIMS: The effect of dietary micronutrients on non-erosive reflux disease (NERD) and reflux esophagitis is unclear. We aim to evaluate the gender-specific effect of micronutrient on erosive esophagitis and NERD. METHODS: A total of 11 690 participants underwent endoscopy and completed 3-day recordings for dietary intake and questionnaires for reflux symptoms from 2004 to 2008. To evaluate the effect of dietary micronutrients on NERD or erosive esophagitis, adjusted regression analysis with odds ratio (OR) and 95% confidence interval (CI) was used. In addition, we performed gender-specific analysis. RESULTS: Prevalence of NERD and erosive esophagitis was 6.8% and 11.2% in men and 9.1% and 2.4% in women. In adjusted analysis, high intake of vitamin A (OR, 0.78; 95% CI, 0.64–0.96), retinol (OR, 0.73; 95% CI, 0.59–0.90), vitamin B2 (OR, 0.68; 95% CI, 0.54–0.87), vitamin B6 (OR, 0.75; 95% CI, 0.58–0.96), folic acid (OR, 0.77; 95% CI, 0.62–0.96), calcium (OR, 0.66; 95% CI, 0.53–0.82), and iron (OR, 0.68; 95% CI, 0.53–0.87) had an inverse association with NERD. However, erosive esophagitis has no relationship with micronutrients except vitamin C (OR, 0.78; 95% CI, 0.62–0.98). High dietary intake of calcium reduced the risk of NERD in men and high dietary intake of many micronutrients reduced NERD in women. CONCLUSIONS: While many dietary micronutrients reduced NERD, they had no effect on erosive esophagitis. The effect of micronutrient on NERD was more prominent in women than men.

ABSTRACT

Ophiopogon japonicus is one of the commonly used medicines,and it has gradually become a therapeutic food for people's daily health care. O. japonicus in Sichuan province is the famous Dao-di herbs in Sichuan province,and is mainly produced in Santai county,Sichuan province. With the unique geographical advantage,Santai county plans to declare the new food raw materials of O. japonicus based on the geographical indication products( Fu Cheng O. japonicus),so it is necessary to analyze and evaluate the nutritional components of O. japonicus in Santai county. The experimental results showed that the content of the nutrients was characterized by low fat,high polysaccharide,high potassium and high vitamin B2,which can be developed as new food raw materials.

ABSTRACT

BACKGROUND: The correlations between the amount of daily fiber intake and bone mineral densities (BMDs) in Korean adult population were investigated in our study. METHODS: Utilizing the Korean National Health and Nutrition Examination Survey in 2011, multivariable linear regression was performed to explore the association between fiber consumption and BMD of lumbar vertebrae 1 to 4 (L1–4 total), L1, L2, L3, and L4 vertebrae, femur neck, femur total, and trochanter. All models were adjusted for age, body mass index, vitamin D level, smoking, physical activity, alcohol use, contraceptive use, hormonal replacement therapy, consumption of carbohydrate, protein, fat, calcium, phosphate, iron, thiamine, riboflavin, niacin, and vitamin C. RESULTS: In males aged between 18 and 45, fiber intake significantly increased BMDs of L1 (coefficient β=0.004, P=0.040) and L2 (β=0.004, P=0.038) while daily protein consumption significantly lowered BMDs of femur neck (β=−0.001, P=0.009), femur total (β=−0.001, P=0.008), and trochanter (β=−0.001, P=0.008). In males aged 65 and older, nutrient intake shows no significant correlations with BMDs except fat consumption was inversely associated with BMD of trochanter (β=−0.001, P=0.017). In females aged between 18 and 45, fiber intake shows no significant relationship with BMDs while daily fat consumption significantly increased BMDs of L1 (β=0.001, P=0.028), L2 (β=0.001, P=0.024), L3 (β=0.001, P=0.033), and L1–4 total (β=0.001, P=0.017). CONCLUSIONS: Fiber intake was a protective factor of lumbar spine (L1 and L2) BMD in male aged between 18 and 45 but not in female participants of any age groups.

ABSTRACT

PURPOSE: This study examined the changes in the nutrient intake and the prevalences of obesity and metabolic syndrome according to the eating alone behavior in middle-aged men and women. METHODS: The data from the 2013 ~ 2017 Korean National Health and Nutrition Examination Survey were analyzed. A total of 7,728 adults (3,404 male, 4,324 female) aged 40 ~ 64 years old were included. The subjects were classified into three groups according to the number of times eating alone per day (0, 1 ~ 2, and 3 times/day). Dietary data were collected by a 1-day 24-h recall. The nutrient intakes were compared among the three groups. Survey logistic regression analyses were conducted to examine the association of the eating alone behavior with obesity and metabolic syndrome, adjusting for the related confounding variables. RESULTS: In men, eating alone was associated significantly with a lower intake of potassium (p-for-trend = 0.048) and lower intake of calories from protein (p-for-trend = 0.04). In women, the proportion of subjects consuming energy less than 75% of the estimated energy requirement (p = 0.001) and less than the estimated adequate requirement of riboflavin (p < 0.001) differed significantly according to the eating alone behavior. The eating alone behavior was positively associated with an increased risk of developing metabolic syndrome (p-for-trend = 0.033), increased blood pressure (p-for-trend < 0.001), and increased waist circumference (p-for-trend = 0.004). On the other hand, in women, however, the eating alone behavior was associated with a decreased risks of developing obesity (p-for-trend = 0.02). No association was found between the eating alone behavior and the risk of metabolic syndrome in women. CONCLUSION: These results suggest that the eating alone behavior is a risk factor for the development of metabolic syndrome in middle-aged Korean men.

ABSTRACT

BACKGROUND/OBJECTIVES: The aim of this study was to analyze specific foods influencing absolute nutrient intake and between-person variations of nutrient intake among Korean preschoolers. SUBJECTS/METHODS: This study included 2,766 participants aged 1–5 years in the 2009–2013 Korea National Health and Nutrition Examination Surveys. Dietary data were obtained from a 24-h dietary recall method. Major food sources of absolute nutrient intake were evaluated based on percent contribution of each food. To assess the contribution of specific foods to between-person variations in nutrient intake, stepwise multiple regressions were performed and cumulative R2 was used. RESULTS: White rice and milk were main food sources of energy, protein, carbohydrate, phosphorus, iron, potassium, thiamin, riboflavin, and niacin. The percentage of fat contributed by milk was 21.3% which was the highest, followed by pork, soybean oil, and egg. White rice accounted for 25% and 40% of total variability in total energy and carbohydrate intakes, respectively. About 39% of variation in calcium intake was explained by milk while 40% of variation in phosphorous intake was explained by cheese. The top 10 foods contributing to between-person variations in nutrient intakes were similar with food items that mainly contributed to absolute nutrient intakes. The number of foods explaining 90% of absolute amounts of nutrient intakes varied from 28 for vitamin A to 80 for iron. CONCLUSIONS: This study identified specific foods that contributed to absolute nutrient intakes and between-person variations in nutrient intakes among Korean preschoolers. Our findings can be used to develop dietary assessment tools and establish food-based dietary guidelines for young children.

ABSTRACT

OBJECTIVES: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. RESULTS: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. CONCLUSIONS: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.
