    社会经济水平是决定饮食质量的重要因素之一。零食偏好受社会经济水平的影响。这项研究的目的是确定社会经济水平对不同社会经济背景的青少年饮食质量和零食偏好的影响。
    该研究涉及居住在伊斯坦布尔的118名10-18岁青少年。研究人员准备的问卷被用来获取青少年饮食习惯的信息,主餐和小吃的消费,习惯,和食物消费记录。参与者的食物消耗使用回顾性24小时召回方法进行评估,使用计算的营养充足率(NAR)和平均充足率(MAR)评估饮食质量。
    青少年的平均年龄为16.42±0.89岁。发现私立学校消费的零食数量高于公立学校(p<0.05)。与公立学校相比,私立学校的维生素C消耗NAR得分明显更高(p<0.05)。尽管私立学校青少年的MAR分数高于公立学校,这一差异无统计学意义.大多数私立学校的青少年经常食用新鲜水果(67.2%),牛奶(60.3%),酸奶(60.3%),和坚果(56.9%)作为零食。相比之下,45%的公立学校青少年经常食用糕点(p<0.05)。
    据观察,与私立学校相比,在公立学校学习的青少年更倾向于选择健康食品作为零食。社会经济水平被认为是影响青春期饮食习惯的重要因素。考虑到在私立学校和公立学校学习的青少年之间的收入水平有很大差异,在私立学校学习的青少年对零食的消费增加可能与收入增加有关。
    Socioeconomic level is one of the important factors determining diet quality. Snack preferences are affected by socioeconomic level. The objective of this research was to determine the effect of socioeconomic levels on diet quality and snack preferences among adolescents from different socioeconomic backgrounds.
    The study involved 118 adolescents aged between 10-18 years residing in Istanbul. A questionnaire prepared by the researchers was used to obtain information on the adolescents\' dietary habits, consumption of main meals and snacks, habits, and food consumption records. The participants\' food consumption was assessed using the retrospective 24-hour recall method, and diet quality was evaluated using the calculated nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR).
    The mean age of the adolescents was 16.42±0.89 years. The number of snacks consumed in private schools was found to be higher than in public schools (p < 0.05). The NAR score for vitamin C consumption was significantly higher in private schools compared to public schools (p < 0.05). Although the MAR scores of adolescents in private schools were higher than those in public schools, this difference was not statistically significant. The majority of adolescents in private schools regularly consumed fresh fruit (67.2%), milk (60.3%), yogurt (60.3%), and nuts (56.9%) as snacks. In contrast, 45% of adolescents in public schools regularly consumed pastries (p < 0.05).
    It was observed that adolescents studying in public schools had a lower tendency to prefer healthy foods for snacks compared to those in private schools. Socioeconomic level was identified as an important factor influencing eating habits during adolescence. Considering that the level of income is significantly different between the adolescents studying at private and public schools, the higher consumption of snacks by the adolescents studying at private school may be associated with higher income.

    背景:这项研究的目的是:1)评估9-18岁印度儿童和青少年的饮食多样性评分(DDS)和食物多样性评分(FVS);2)比较DDS和FVS与人口统计学的关联,社会经济,和健康特征(生长和血红蛋白[Hb]浓度);和3)确定DDS和FVS截止值以确定膳食微量营养素充足性。
    方法:这项研究是在印度六个州的城市和农村地区的多中心研究(2016-2017)中注册的儿童和青少年的子集(n=1845)中进行的。高度,体重,和Hb测量,并计算人体测量Z评分。使用结构化问卷收集社会人口统计学数据。通过24小时饮食回忆收集的饮食数据用于计算DDS和FVS。计算了10种微量营养素的平均充足率(MAR)。进行接收器工作特性分析以定义DDS和FVS的截止值。
    结果:与农村地区的儿童和青少年相比,城市儿童和青少年消费更多样化的饮食(城市,4.1±1.1;农村,3.5±1;P<0.01),平均FVS较高(城市,19.9±5.7;农村,15.9±4.5;P<0.01)。DDS和FVS均呈显著相关(r=0.860;P<0.01),与MAR呈正相关,增长,血红蛋白(P<0.001)和母亲的文化程度(P<0.01)。确定≥6.5(DDS)和≥17(FVS)的临界值以预测微量营养素的充足性。
    结论:DDS和FVS可以互换用于评估生长,健康状况,和营养充足。DDS和FVS的单一临界值可能有助于迅速识别微量营养素不足的儿童和青少年。
    The objectives of this study were to 1) evaluate the dietary diversity scores (DDS) and food variety scores (FVS) among Indian children and adolescents aged 9-18 y; 2) compare the DDS and FVS in association with demographic, socioeconomic, and health characteristics (growth and hemoglobin [Hb] concentrations); and 3) determine DDS and FVS cutoffs to identify dietary micronutrient adequacy.
    This study was performed in a subset (n = 1845) of children and adolescents enrolled in a multicenter study (2016-2017) from urban and rural areas of six Indian states. Height, weight, and Hb were measured, and anthropometric Z-scores were computed. Sociodemographic data were collected using a structured questionnaire. Dietary data collected by 24-h dietary recall were used to calculate the DDS and FVS. The mean adequacy ratio (MAR) for 10 micronutrients was computed. Receiver operating characteristic analysis was performed to define cutoffs of DDS and FVS.
    In comparison with children and adolescents from rural areas, urban children and adolescents consumed more diverse diets (urban, 4.1 ± 1.1; rural, 3.5 ± 1; P < 0.01) and had a higher mean FVS (urban, 19.9 ± 5.7; rural, 15.9 ± 4.5; P < 0.01). Both the DDS and FVS were significantly correlated with each other (r = 0.860; P < 0.01) and were positively correlated with MAR, growth, and Hb (P < 0.001) and mother\'s educational level (P < 0.01). The cutoffs of ≥6.5 (DDS) and ≥17 (FVS) were determined to predict micronutrient adequacy.
    Both the DDS and FVS can be used interchangeably for assessing growth, health status, and nutritional adequacy. Single cutoff values of the DDS and FVS may aid in prompt identification of children and adolescents with micronutrient inadequacy.

    很少有意大利和欧洲的研究使用饮食记录评估小学生对饮食建议的依从性。没有意大利研究提供基于指数的营养充足性评估。我们从NAC-II队列研究中对381名7岁儿童的饮食摄入量进行了全面概述。FriuliVeneziaGiulia(意大利)。能源,宏-,和微量营养素摄入量来自3天的饮食记录。使用标准(中位数和百分比)和基于指数的(营养充足比(NAR)和平均充足比(MAR))方法来评估营养和总体饮食水平对意大利饮食参考值的充分性。大量营养素对能量摄入的百分比(%En)对总脂肪和蛋白质的贡献不平衡。25%的儿童总脂肪摄入量超过参考摄入量上限。在约63%的儿童中,蛋白质摄入量在儿童人群参考摄入量中至少增加了一倍.钠摄入量中位数(1.7克/天),饱和脂肪酸(12.2%En),在大多数(65-84%)儿童中,可溶性碳水化合物(19.4%En)超过了建议的饮食目标。还观察到微量营养素不足,中位数NAR范围从0.11(维生素D)到0.90(锌)。MAR中位数为0.75(0.69-0.79),1表示最佳的整体饮食摄入量。总之,登记的儿童表现出几种宏量和微量营养素的摄入欠佳,符合意大利和欧洲对小学生的研究。根据目前的调查结果,公共卫生干预措施可能针对特定营养素或亚人群。
    Few Italian and European studies have assessed adherence to dietary recommendations in primary school children using dietary records. No Italian studies have provided an index-based nutritional adequacy assessment. We provided a comprehensive overview of dietary intake in 381 7-year-old children from NAC-II cohort study, Friuli Venezia Giulia (Italy). Energy, macro-, and micronutrient intakes were derived from 3-day dietary records. Standard (median and percentage) and index-based (Nutrient Adequacy Ratio (NAR) and Mean Adequacy Ratio (MAR)) approaches were used to evaluate adequacy to Italian dietary reference values at nutrient- and overall-diet-level. Percentage contribution of macronutrients to energy intake (%En) was unbalanced towards total fats and protein. In 25% of children, total fats intake exceeded the reference intake upper limit. In ~63% of children, protein intake was at least doubled in their child-specific population reference intake. Median intakes of sodium (1.7 g/day), saturated fatty acids (12.2 %En), and soluble carbohydrates (19.4 %En) exceeded the suggested dietary target in most (65-84%) children. Inadequacy was also observed for micronutrients, with median NARs ranging from 0.11 (vitamin D) to 0.90 (zinc). The median MAR was 0.75 (0.69-0.79), with 1 indicating optimal overall dietary intake. In conclusion, the enrolled children showed suboptimal intakes of several macro- and micronutrients, in line with Italian and European studies on primary school children. Based on the current findings, public health interventions may be targeted to specific nutrients or subpopulations.

    饮食多样性和充足的营养摄入对于健康生活至关重要。然而,低收入地区的女性在确保饮食质量方面经常面临困难.这项研究评估了饮食多样性之间的关系,营养充足,吉尔吉斯斯坦育龄妇女的社会经济因素。在四个地点进行了横断面研究,包括吉尔吉斯斯坦北部和南部的两个农村地区和两个城市地区。在对423名18-49岁的WRA进行采访时,进行了一项带有预编码和开放式问题的调查。数据收集于2021年3月至5月进行。WRA的平均体重指数(BMI)为24.2±4.6kg/m2。北方地区(cles=0.61,p<0.05)有农田(cles=0.60,p<0.001)和农场动物(cles=0.60,p<0.05)的农村妇女的饮食多样性得分(DDS)较高(共同语言效应大小)cles=0.67,调整后p<0.001)。大多数微量营养素的平均营养充足率(NAR)低于1,而硫胺素,核黄素,维生素B6和C,叶酸,钙,镁甚至低于0.5。拥有厨房花园或农田的女性拥有更好的NAR能量(cles=0.57),NAR碳水化合物(cles=0.60),NAR光纤(cles=0.60),NAR维生素B1(cles=0.53),和NAR叶酸(cles=0.54)。收到汇款和农场动物的受访者对能源有更好的NAR,碳水化合物,纤维,维生素B1,叶酸,铁,锌,和16种营养素的平均充足率(MAR16)比那些没有的人。教育程度和收入与膳食质量呈负相关。这项研究为吉尔吉斯斯坦饮食质量的有限文献做出了贡献。隐藏的饥饿和营养不良是低收入环境中WRA的一个严重问题。建议包括营养研究计划,教授家庭农业实践,并提高对充足营养的认识。
    Dietary diversity and adequate nutrient intake are essential for conducting a healthy life. However, women in low-income settings often face difficulties in ensuring dietary quality. This research assessed relationships between the dietary diversity, nutrient adequacy, and socio-economic factors among women of reproductive age (WRA) in Kyrgyzstan. A cross-sectional study was undertaken in four locations, including two rural and two urban areas in the north and south of Kyrgyzstan. A survey with pre-coded and open-ended questions was employed during the interviews of 423 WRAs aged 18-49. Data collection was conducted in March-May 2021. The average value body mass index (BMI) of WRA was 24.2 ± 4.6 kg/m2. The dietary diversity score (DDS) was higher among rural women (common language effect size) cles = 0.67, adjusted p < 0.001) in the northern region (cles = 0.61, p < 0.05) who have cropland (cles = 0.60, p < 0.001) and a farm animal (cles = 0.60, p < 0.05). Mean nutrient adequacy ratio (NAR) was below 1 in most micronutrients, whereas thiamine, riboflavin, vitamins B6 and C, folic acid, calcium, and magnesium were even lower than 0.5. Women with a kitchen garden or a cropland had better NAR energy (cles = 0.57), NAR carbohydrate (cles = 0.60), NAR fiber (cles = 0.60), NAR vitamin B1 (cles = 0.53), and NAR folic acid (cles = 0.54). Respondents who receive remittances and a farm animal have better NARs for energy, carbohydrates, fiber, vitamin B1, folic acid, iron, zinc, and mean adequacy ratio for 16 nutrients (MAR 16) than those who do not. Education and income have a negative correlation with dietary quality. This study contributes to the limited literature on the quality of diets in Kyrgyzstan. Hidden hunger and undernutrition are a severe problem among WRA in low-income settings. Recommendations are including study programs in nutrition, teaching households farming practices, and raising awareness on adequate nutrition.

    This study aimed to evaluate the status of dietary diversity and nutrient intake among Han and Dongxiang smallholder farmers in poor rural areas of northwest China. In this cross-sectional study, dietary intake was assessed in 499 smallholder farmers aged 18-75 years from two nationally designated impoverished counties in Gansu Province, China, using three consecutive 24 h dietary recalls. The dietary diversity score (DDS) and nutrient adequacy ratio (NAR) were adopted to assess dietary diversity and micronutrient adequacy, respectively. The mean DDS (range from 1 to 9) in participants was relatively low (3.81 ± 1.01). Consumption of grains was excessive, while consumption of vegetables, fruits, meat, beans, eggs, fish, and dairy was inadequate. The NAR values were higher in Han Chinese, with the exceptions of vitamin C, potassium, pyridoxine, and selenium (p < 0.05). For each nutrient, the high DDS group had a higher mean NAR (p < 0.05), except for pyridoxine. High household monthly income, being Han Chinese, high DDS, and being aged over 45 years were positively associated with mean adequacy ratio (MAR) of 14 micronutrients evaluated. Lack of dietary diversity and insufficient intake of essential micronutrients are public health concerns in northwest China. Nutrition education and other proper methods to address these issues are needed.

    OBJECTIVE: The double burden of malnutrition is an emerging public health concern nowadays which a correlation with obesity. This study aimed to examine the relationship between resting metabolic rate (RMR) and dietary intake of zinc, vitamin C, and riboflavin in overweight and obese women.
    RESULTS: The RMR/FFM showed a significant association with riboflavin (β = 1.59; 95% CI 1.04-23.26, P = 0.04) and zinc (β = 0.78; 95% CI 1.04-4.61, P = 0.03) in the crude model. Moreover, differences in vitamin C and RMR/FFM was marginal significant (β = 0.75; 95% CI 0.95-4.77, P = 0.06). After adjusting for confounders the riboflavin association change to marginal significance (β = 1.52; 95% CI 0.91-23.04, P = 0.06). After controlling for potential confounders, the associations change between zinc and RMR/FFM (β = 0.66; 95% CI 0.78-4.86, P = 0.15) and between RMR/FFM and vitamin C (β = 0.48; 95% CI 0.66-3.96, P = 0.28). Our study showed a significant association between dietary intake of zinc, riboflavin, and vitamin C and change in RMR/FFM in overweight and obese women.

    Preliminary studies suggest that a modified Paleolithic diet may benefit symptoms of fatigue in progressive multiple sclerosis (MS). However, this diet restricts the consumption of eggs, dairy, and gluten-containing grains, which may increase the risk of micronutrient deficiencies. Therefore, we evaluated the nutritional safety of this diet among people with progressive MS. Three nonconsecutive 24-h dietary recalls were collected from (n = 19) progressive MS participants in the final months of a diet intervention study and analyzed using Nutrition Data System for Research (NDSR) software. Food group intake was calculated, and intake of micronutrients was evaluated and compared to individual recommendations using Nutrient Adequacy Ratios (NARs). Blood was drawn at baseline and the end of the study to evaluate biomarker changes. Mean intake of fruits and vegetables exceeded nine servings/day and most participants excluded food groups. The intake of all micronutrients from food were above 100% NAR except for vitamin D (29.6 ± 34.6%), choline (73.2 ± 27.2%), and calcium (60.3 ± 22.8%), and one participant (1/19) exceeded the Tolerable Upper Limit (UL) for zinc, one (1/19) for vitamin A, and 37% (7/19) exceeded the chronic disease risk reduction (CDRR) for sodium. When intake from supplements was included in the analysis, several individuals exceeded ULs for magnesium (5/19), zinc (2/19), sodium (7/19), and vitamins A (2/19), D (9/19), C (1/19), B6 (3/19), and niacin (10/19). Serum values of vitamins D, B12, K1, K2, and folate significantly increased compared to respective baseline values, while homocysteine and magnesium values were significantly lower at 12 months. Calcium and vitamin A serum levels did not change. This modified Paleolithic diet is associated with minimal nutritional risks. However, excessive intake from supplements may be of concern.

    在过去的十年中,已经发布了许多有关幼儿喂养建议的更新,但同时摄入趋势尚未评估.
    这项研究的目的是通过使用2002年,2008年和2016年的喂养婴儿和幼儿研究(FITS)数据,评估美国0-47.9个月婴儿和儿童的能量和营养摄入量的充足性和趋势。
    FITS是对婴幼儿父母/照顾者的横断面调查(FITS2002,n=2962;FITS2008,n=3276;FITS2016,n=3235)。使用营养数据系统进行研究,通过电话与训练有素的面试官一起评估饮食摄入量。计算平均±SE营养素摄入量。用17种营养素的营养充足率(NAR)和相应的平均充足率评估饮食充足性。
    在调查中,能量和大量营养素的摄入量总体上是稳定的,但在6-11.9-mo-old和12-23.9-mo-old中观察到饱和脂肪和总糖的显着减少和纤维的增加(P趋势<0.0001)。所有年龄段的平均钠摄入量超过了充足摄入量(AI),而纤维摄入量普遍低于人工智能。NAR值最低的营养素是维生素D(范围为0.41-0.67/1.00)和维生素E(2008年和2016年范围为0.60-0.79/1.00)。对于铁,6~11.9个月婴儿的NAR值最低,为0.77~0.88/1.00,而12~47.9个月婴儿的NAR值为0.85~0.89/1.00.钾从12个月低到47.9个月(调查年的NAR范围为0.55-0.63/1.00)。平均摄入量下降最大的营养素是铁和维生素D和E在6-11.9-moold中,与2002年相比,2016年12-23.9-mo-old中的维生素D和钾。
    美国婴儿和幼儿的饮食通常适合大多数微量营养素,并且随着时间的推移稳定。但钠摄入量太高,营养缺口仍然存在,尤其是维生素D,E,和不同年龄的纤维以及婴儿的铁。
    Many updates to young child feeding recommendations have been published over the past decade, but concurrent intake trends have not been assessed.
    The aim of this study was to evaluate adequacy and trends in energy and nutrient intakes of US infants and children aged 0-47.9 mo through use of Feeding Infants and Toddlers Study (FITS) data from 2002, 2008, and 2016.
    FITS are cross-sectional surveys of parents/caregivers of infants and young children (FITS 2002, n = 2962; FITS 2008, n = 3276; FITS 2016, n = 3235). Dietary intakes were assessed by telephone with trained interviewers using the Nutrition Data System for Research. Mean ± SE nutrient intakes were calculated. Diet adequacy was assessed with the nutrient adequacy ratio (NAR) for 17 nutrients and the corresponding mean adequacy ratio.
    Energy and macronutrient intakes were generally stable across surveys, but significant decreases for saturated fat and total sugars and an increase in fiber were observed among 6-11.9-mo-olds and 12-23.9-mo-olds (P-trend < 0.0001). Mean sodium intakes exceeded Adequate Intakes (AI) for all ages, whereas fiber intakes were universally below the AI. Nutrients with the lowest NAR values were vitamin D (range 0.41-0.67/1.00) and vitamin E (range 0.60-0.79/1.00 for 2008 and 2016). For iron, infants aged 6-11.9 mo had the lowest NAR values at 0.77-0.88/1.00, compared to 0.85-0.89/1.00 for 12-47.9-mo-olds. Potassium was low from 12 to 47.9 mo (NAR range 0.55-0.63/1.00 across survey years). The nutrients with the greatest decline in mean intakes were iron and vitamins D and E among 6-11.9-mo-olds, and vitamin D and potassium among 12-23.9-mo-olds in 2016 compared to 2002.
    The diets of US infants and young children were generally adequate for most micronutrients and stable over time, but sodium intakes were too high, and nutrient gaps still existed, especially for vitamins D, E, and fiber across ages and for iron among infants.

    Objectives: Diabetic nephropathy may adversely influence on sleep duration. The quality of diet may also be affected by both sleep duration and diabetes nephropathy. Therefore, lower diet quality in short sleepers-diabetic nephropathy patients might be related to higher metabolic abnormalities. In the present study, we investigated if sleep duration is related to diet quality indices and biochemical markers in diabetic nephropathy patients. Method: This cross-sectional study was conducted among 237 diabetic nephropathy patients, randomly selected from patients attending in the Alzahra University Hospital, Isfahan, Iran. Usual dietary intake was assessed using validated food frequency questionnaire. Diet quality indices (including diet diversity score, dietary energy density, mean adequacy ratio, and nutrient adequacy ratio) were calculated based on standard definitions. Sleep duration was estimated using self-reported nocturnal hours of sleep. Results: Short sleepers (5-6 h) had higher blood urea nitrogen and creatinine compared with those who slept more than 7.5 h (20.26 + 0.23 mg/dl vs. 17.61 + 0.30 mg/dl, P < 0.0001, and 1.98 + 0.27 mg/dl vs. 1.90 + 0.24 mg/dl, P = 0.03, respectively). Serum triglyceride levels were positively correlated with sleep duration (P = 0.02). Diet quality indices were not significantly associated with sleep duration. Conclusion: Higher sleep duration is significantly related to lower kidney-related biomarkers in diabetic nephropathy patients. Diet quality indices were not associated with sleep duration in diabetic nephropathy patients. More longitudinal studies are required to evaluate the associations of sleep duration, diet quality and biochemical markers in diabetic nephropathy patients.

    UNASSIGNED: Dietary diversity scores (DDS) are simple indicators often used as proxies for nutrient adequacy. A 10-food group indicator is proposed by the Food and Agriculture Organization of the United Nations as a global standard for measuring dietary diversity among women in low-resource settings. However, its validity as a proxy for nutrient adequacy across different agricultural seasons for pregnant women has not been determined.
    UNASSIGNED: We studied associations between DDS and nutrient adequacy ratios (NAR) across two different agricultural seasons (pre- and post-harvest seasons) for pregnant women in rural Malawi and assessed whether a 1-day DDS or a 3-day DDS would be the best indicator of nutrient adequacy.
    UNASSIGNED: Dietary intakes of 330 pregnant women were assessed between gestational weeks 28 and 35. Intakes of energy, macronutrients, and 11 micronutrients were estimated using three repeated interactive 24-h diet recalls, and DDS were also calculated from these days. Correlation coefficients (r) between DDS, NAR, and mean adequacy ratio (MAR) of the 11 micronutrients were determined.
    UNASSIGNED: After energy adjustments, we found significant correlations between DDS and MAR with both DDS indicators in the preharvest season (r = 0.22-0.23; p < 0.001) but not in the post-harvest season (p > 0.05). For individual energy-adjusted NARs, correlations were not consistently significant across the two seasons and the two DDS indicators.
    UNASSIGNED: Our results suggest that DDS could be used to predict overall nutrient adequacy during the preharvest season. As similar correlations were found using both the 1- and 3-day indicators, we recommend using a 1-day DDS, for simplicity. However, as the indicators are sensitive to seasonality they should be used with care in this study setting.
