    这是关于东地中海地区婴幼儿饮食摄入量的第一项研究,一个目前正在经历营养转型的地区。它旨在描述黎巴嫩0-4岁儿童的食物消费模式,评估他们的大量和微量营养素摄入量,并评估对饮食建议的依从性。
    根据2012年的全国横断面调查(n=866),这项研究收集了社会人口统计学和人体测量特征的数据,并进行了一次24小时饮食召回。将营养素摄入量与参考值进行比较:估计平均需要量(EAR),充足摄入量(AI)和可接受的常量营养素分布范围(AMDR)。
    牛奶是婴儿能量摄入(EI)的最高贡献者(在0-5.9个月和6-11.9个月的婴儿中分别为95.8和56.5%,分别),虽然幼儿和学龄前儿童的摄入量较低(35.4%和15.1%,分别)。相比之下,与幼儿相比,学龄前儿童的甜食和甜味饮料摄入量最高,在学龄前儿童中贡献18.5%的EI。与饮食指南相比,饮食依从性最低的是蔬菜(17.8-20.7%)和水果(14.4-34.3%)。蛋白质摄入量在绝大多数儿童的建议范围内。尽管与婴儿相比,幼儿和学龄前儿童的总脂肪摄入量较低,超过40%的幼儿和学龄前儿童的脂肪超过AMDR,87.3%的学龄前儿童的饱和脂肪超过上限.只有3.6%的幼儿和11.5%的学龄前儿童超过膳食纤维的AI水平。微量营养素摄入量评估显示,婴儿的平均摄入量超过了所有微量营养素的AI,除了维生素D和镁.在幼儿中,维生素D和钙低于EAR,分别为84.7%和44.6%,分别。在学龄前儿童中,大多数儿童(91.9%)维生素D摄入不足,三分之一的人叶酸摄入量不足,
    这项研究确定了黎巴嫩婴幼儿营养干预的优先问题。需要多方利益攸关方共同努力,在生命早期灌输更健康的食物消费和营养摄入模式。
    This is the first study on dietary intakes of infants and young children in the Eastern Mediterranean Region, a region that is currently witnessing the nutrition transition. It aims at characterizing food consumption patterns amongst 0-4 year old children in Lebanon, evaluating their macro- and micronutrient intakes and assessing adherence to dietary recommendations.
    Based on a national cross-sectional survey in 2012 (n = 866), the study collected data on sociodemographic and anthropometric characteristics, and one 24-hour dietary recall was administered. Nutrient intakes were compared with reference values: Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR).
    Milk was the highest contributor to energy intake (EI) in infants (95.8 and 56.5% in 0-5.9 months and 6-11.9 months old infants, respectively), while its intake was lower among toddlers and preschoolers (35.4 and 15.1%, respectively). In contrast, intakes of sweets and sweetened beverages were the highest in preschoolers compared to younger children, contributing 18.5% EI in preschoolers. Compared to dietary guidelines, the lowest dietary adherence was found for vegetables (17.8-20.7%) and fruits (14.4-34.3%). Protein intake was within the recommendations for the vast majority of children. Although total fat intake was lower in toddlers and preschoolers compared to infants, more than 40% of toddlers and preschoolers exceeded the AMDR for fat and 87.3% of preschoolers exceeded the upper limit for saturated fat. Only 3.6% of toddlers and 11.5% of preschoolers exceeded the AI level for dietary fiber. Micronutrient intake assessment showed that mean intakes in infants exceeded the AI for all micronutrients, except for vitamin D and magnesium. In toddlers, vitamin D and calcium were below the EAR among 84.7, and 44.6%, respectively. In preschoolers, most of the children (91.9%) had inadequate intakes of vitamin D, and a third had inadequate intakes of folate, calcium and vitamin A.
    This study identified priority issues for nutrition intervention in infants and young children in Lebanon. Concerted multi-stakeholder efforts are needed to instill heathier food consumption and nutrient intake patterns early in life.

    关于膳食钙摄入与溃疡性结肠炎(UC)的关联的数据有限。我们旨在调查伊朗成年人膳食钙摄入量与UC患病率之间的关系。在这项基于人群的病例对照研究中,在伊朗炎症性肠病登记处注册的由胃肠病学家诊断的UC患者被纳入病例.年龄和性别匹配的健康对照者从心理流行病学研究中选择,食物健康与营养(SEPAHAN)数据集。通过经过验证的食物频率问卷检查参与者的饮食钙摄入量。我们在分析中纳入了327名中年参与者(109例和218例对照);其中52.1%是女性。在调整了潜在的混杂因素后,在膳食钙摄入量的第三个三分位数的个体患UC的几率降低了92%,与第一三分位数相比(OR=0.08,95%CI0.02-0.27)。我们基于推荐的膳食配额(RDA)摄入量的分析表明,膳食钙摄入量不足与UC的几率增加有关(OR=9.5,95%CI2.98-30.91)。按性别进行的分层分析表明,这些关联在两种性别中都很重要;尽管结果在男性人群中更为明显。在膳食钙摄入量的三元组中观察到UC的几率显着下降趋势,在男性和女性。伊朗成年人较高的膳食钙摄入量与较低的UC患病率相关。膳食钙摄入不足也与UC的几率升高有关。需要进一步的前瞻性调查来确认这些发现。
    Limited data are available on the association of dietary calcium intake and ulcerative colitis (UC). We aimed to investigate the relation between dietary calcium intake and UC prevalence in Iranian adults. In this population-based case-control study, diagnosed patients with UC by gastroenterologists that were registered in the Iranian inflammatory bowel disease registry were included as cases. Age and sex-matched healthy controls were selected from Study on the Epidemiology of Psychological, Alimentary Health and Nutrition (SEPAHAN) dataset. Dietary calcium intakes of participants were examined through a validated food frequency questionnaire. We included 327 middle-aged participants (109 cases and 218 controls) in the analysis; 52.1% of them were females. After adjustments for potential confounders, individuals in the third tertile of dietary calcium intake had 92% lower odds of UC, compared to those in the first tertile (OR = 0.08, 95% CI 0.02-0.27). Our analysis based on recommended dietary allowances (RDAs) intake showed that dietary Ca intake deficiency was related to increased odds of UC (OR = 9.5, 95% CI 2.98-30.91). Stratified analysis by gender revealed that these associations were significant in both genders; although the results were stronger in the male population. A Significant decreasing trend was observed for odds of UC in tertiles of dietary calcium intakes, in both males and females. Higher dietary calcium intake was associated with lower UC prevalence in Iranian adults. Inadequate dietary calcium intake was also linked to elevated odds of UC. Further prospective investigations are needed to affirm these findings.

    该行业使用营养和健康声明,优质优惠,和促销角色作为营销策略(MS)。在超加工产品中包含这些MS可能会影响儿童和青少年的购买行为。这项研究确定了携带索赔和营销策略的食品比例,还有关键营养素申报产品的比例,以及在哥斯达黎加销售的超加工食品的包装正面(FoP)上带有或不带有索赔的产品与MS之间的营养特征差异。数据来自2423张照片,这些照片是2015年在哥斯达黎加最广泛和最受欢迎的连锁超市之一出售的七个食品集团的零食。百分之十的产品缺乏营养事实小组。钠是报道最少的关键营养素。能量和关键营养素在不包括任何营养或健康声明的产品和包含至少一种MS的产品中显著最高。44%和10%的所有产品显示至少一种营养或至少一种健康声明,分别,23%的人显示至少一个MS。总之,需要制定法规来限制超加工食品包装的索赔和营销,以产生更健康的食品环境,并有助于预防哥斯达黎加的儿童和青少年肥胖。
    The industry uses nutrition and health claims, premium offers, and promotional characters as marketing strategies (MS). The inclusion of these MS on ultra-processed products may influence child and adolescent purchase behavior. This study determined the proportion of foods carrying claims and marketing strategies, also the proportion of products with critical nutrients declaration, and nutritional profile differences between products that carry or not claims and MS on the front-of-package (FoP) of ultra-processed food products sold in Costa Rica. Data were obtained from 2423 photographs of seven food groups consumed as snacks that were sold in one of the most widespread and popular hypermarket chains in Costa Rica in 2015. Ten percent of products lacked a nutrition facts panel. Sodium was the least reported critical nutrient. Energy and critical nutrients were significantly highest in products that did not include any nutrition or health claim and in products that included at least one MS. Forty-four percent and 10% of all products displayed at least one nutrition or at least one health claim, respectively, and 23% displayed at least one MS. In conclusion, regulations are needed to restrict claims and marketing on ultra-processed food packages to generate healthier food environments and contribute to the prevention of childhood and adolescent obesity in Costa Rica.

    A study was conducted to evaluate whether preeclampsia in pregnant women is associated with dietary factors and antioxidant intake (vitamin C, vitamin E, vitamin A, and selenium).
    In this case-control study, a group of 79 pregnant Jordanian women (36 preeclamptic pregnant women and 43 healthy pregnant women aged 18-45 years with a gestational age ≥20th week of pregnancy) were recruited from the obstetrics and gynecology clinics at Royal Medical Services, King Hussein Medical Center, Amman, Jordan. Information about socio-demographics, anthropometric measurements, biochemical measurements, nutritional intake, and dietary habits was collected through a structured interview. Three 24-hour dietary records were also made. Data were analyzed using Statistical Package for the Social Sciences (SPSS), and dietary intake was analyzed using ESHA software. Prepregnancy BMI, age, multiple pregnancies, energy intake, beta-carotene, vitamin C, and sodium showed significant difference between preeclamptic pregnant women and healthy pregnant women. The odds ratio (OR) and the corresponding 95% confidence interval (CI) show that a strong association with preeclampsia exists for the intake of fat (OR = 6.40, 95% CI: 1.85-22.17) and saturated fat (OR = 3.35, 95% CI: 1.0-11.54). Inverse associations with preeclampsia were found for fruit intake (OR = 0.16, 95% CI: 0.47-0.55) and olive oil intake (OR = 0.20, 95% CI: 0.05-0.78).
    In this case-control study in Jordanian pregnant women, preeclampsia was associated with a high intake of fat, saturated fat, and sodium and a low intake of fruits, fiber, vitamin C, B-carotene, and olive oil.

    OBJECTIVE: The prevalence of ulcerative colitis (UC) has been increasing in Japan. Trace elements, such as iron, zinc, magnesium, and copper, can cause digestive symptoms where there is a deficiency or excess. We focused on the dietary intake of trace elements and their associations with UC development.
    METHODS: A multicenter, hospital-based case-control study was conducted in Japan. Cases were 127 newly diagnosed UC patients, and 171 age-matched and sex-matched hospital controls were recruited. We considered that UC patients had potentially changed their dietary habits due to disease symptoms. The dietary habits were investigated using a self-administered diet history questionnaire to analyze the dietary intakes and frequencies at two points, the previous 1 month and 1 year before.
    RESULTS: In the assessment of dietary habits 1 year before, the highest intake of iron showed an increased odds ratio (OR) for UC on multivariate analysis (OR = 4.05, 95% confidence interval, 1.46-11.2, P < 0.01). The highest intake of zinc 1 year before showed a decreased OR for UC (OR = 0.39, 95% confidence interval, 0.18-0.85, P = 0.01). Intakes of magnesium and copper had no significant association with UC. Because most UC cases had experienced the first symptom of UC within the previous 11 months, these intakes at 1 year before represented an association with pre-illness dietary habits.
    CONCLUSIONS: A high intake of iron has some effect on the development of UC. In contrast, a high intake of zinc has a protective effect on the development of UC.

    Numerous governments in developing countries institute school lunch programs or school feeding programs as a strategy to address high malnutrition and low education rates among children. In 2005, the Ghanaian government launched the Ghana School Feeding Programme (GSFP). The GSFP policy does not document (1) the actual meal and associated nutrient profile received by the student, (2) the cost of the meal ingredients to the caterer who prepares the food, nor (3) the recipe derivations that may supply an enhanced nutritional profile. We address these 3 information gaps by employing a detailed case study of 4 caterers supplying a traditional tomato stew recipe in northern Ghana within GSFP-supported school lunch programs. Specifically, we explore the following propositions: (1) GSFP caterers can deliver a school lunch for under 100 pesewas (1 GH¢ or $0.21 USD) per student; (2) the meal meets the recommended daily allowance for protein; (3) soy can serve as a cost-effective ingredient to fortify the meal in terms of protein level and protein quality; and (4) significant differences exist in the macro- and micronutrient profile due to caterer discretion. We answer the above 4 propositions, and by doing so show the importance of accurately measuring the nutritional content, costs, and quantities of the actual school lunch under study. Second, among our results, we show the economy of locally produced soy flour as an ingredient that can lower costs and raise nutrition when substituting for other locally produced proteins such as ground beef and mackerel.

    尽管胃癌(GC)的发病率有所下降,它仍然是韩国第二常见的癌症。作为一类植物化学物质,类胡萝卜素是富含水果和蔬菜的脂溶性色素,具有促进健康的特性,包括预防癌症的效果。这项病例对照研究调查了总膳食类胡萝卜素的影响,膳食类胡萝卜素亚类(α-胡萝卜素,β-胡萝卜素,β-隐黄质,叶黄素/玉米黄质,和番茄红素),和食物有助于饮食中摄入每种类胡萝卜素对GC的风险。2011年3月至2014年12月从韩国国家癌症中心医院招募了四百十五例病例和830名对照。在女性中观察到总饮食类胡萝卜素与GC风险之间的显着负相关(比值比(OR)0.56,95%置信区间(CI)0.32-0.99)。饮食中番茄红素的较高摄入量与受试者的总体GC风险呈负相关(OR0.60,95%CI0.42-0.85,趋势p=0.012),男性(OR0.60,95%CI0.39-0.93),和女性(OR0.54,95%CI0.30÷0.96,趋势p=0.039)。在幽门螺杆菌(H.幽门螺杆菌)-阳性受试者和曾经吸烟的人。在膳食番茄红素的主要贡献食品中,在整个受试者中,食用西红柿和番茄酱与GC风险呈负相关,男人,和女人。根据我们的发现,膳食番茄红素和番茄红素的贡献食物(西红柿和番茄酱)的较高摄入量可能与GC的风险呈负相关。
    Although the incidence of gastric cancer (GC) has declined, it remains the second most common cancer in Korea. As a class of phytochemicals, carotenoids are fat-soluble pigments that are abundant in fruits and vegetables and have health-promoting properties, including cancer prevention effects. This case-control study investigated the effects of total dietary carotenoids, dietary carotenoid subclasses (α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin, and lycopene), and foods contributing to the dietary intake of each carotenoid on the risk of GC. Four hundred and fifteen cases and 830 controls were recruited from the National Cancer Center Hospital in Korea between March 2011 and December 2014. A significant inverse association between total dietary carotenoids and GC risk was observed among women (odds ratio (OR) 0.56, 95% confidence interval (CI) 0.32⁻0.99). A higher intake of dietary lycopene was inversely associated with GC risk overall in the subjects (OR 0.60, 95% CI 0.42⁻0.85, p for trend = 0.012), men (OR 0.60, 95% CI 0.39⁻0.93), and women (OR 0.54, 95% CI 0.30⁻0.96, p for trend = 0.039). This significant association between dietary lycopene intake and GC risk was also observed in the subgroups of Helicobacter pylori (H. pylori)-positive subjects and those who had ever smoked. Among the major contributing foods of dietary lycopene, consumption of tomatoes and tomato ketchup was inversely associated with GC risk in the overall subjects, men, and women. Based on our findings, a higher intake of dietary lycopene and contributing foods of lycopene (tomatoes and tomato ketchup) may be inversely associated with the risk of GC.

    Among the factors that may influence fruit and vegetable intake, there is a food neophobia level, but the other elements, including physical activity and place of residence, must also be taken into account as interfering ones. The aim of the study was to analyze the association between food neophobia level and the intake of fruits and vegetables in a nationwide case-control study of Polish adolescents (12⁻13 years), including the influence of gender, the physical activity program participation and the place of residence. The #goathletics Study was conducted among a group of 1014 adolescents, 507 individuals representative for a nationwide physical activity program \"Athletics for All\" participants (characterized by an active lifestyle) and 507 pair-matched individuals (characterized by sedentary behavior), while 502 were representative for urban and 512 for suburban area. The assessment of food neophobia level was based on the Food Neophobia Scale questionnaire and the assessment of fruit and vegetable intake was based on the validated food frequency questionnaire. It was observed that higher food neophobia level is associated with a lower fruit and vegetable intake, that was stated both for girls and boys, as well as both for individuals characterized by an active lifestyle and those characterized by sedentary behavior, both from urban and suburban area. Food neophobic individuals characterized by an active lifestyle and those from urban areas were characterized by a higher fruit intake than individuals characterized by sedentary behavior and those from suburban areas, from the same food neophobia category. It was found that food neophobia may reduce fruit and vegetable intake, but the physical activity education with peers may reduce the observed influence and should be applied especially in the case of neophobic individuals from suburban areas.
