    营养在优化职业足球运动员的健康和表现方面的重要性已经得到了很好的确立。尽管已发布了有关职业足球运动员饮食要求的实用建议,许多球员不符合这些准则。因此,本研究的主要目的是评估有针对性的营养教育和行为改变干预措施对职业足球运动员饮食摄入的影响.此外,先前在该人群中的研究报告了比赛后静息代谢率(RMR)的升高.因此,这项研究的另一个目的是检查饮食摄入的任何变化是否会影响比赛后的RMR.
    来自英超联赛俱乐部职业发展阶段的20名球员(年龄:18.4±1.0岁;体重:76.1±6.0kg;身高:1.80±0.07m)被随机分配到“干预”(INT)组(n=10),他们接受了大量的营养教育和行为改变干预,或“控制”(CON)组(n=10),他们没有得到营养支持。在整个比赛周(比赛日(MD)-2,MD-1,MD,MD+1和MD+2),而在MD-1、MD+1和MD+2上评估RMR。使用两因素(组和日)方差分析(ANOVA)和随后的Bonferroni事后检验,对干预对饮食摄入量和RMR的影响进行了统计分析。
    平均能量(3393±852vs.2572±577kcal·day-1)和CHO(5.36±1.9vs.与INT相比,3.47±1.1g·kg-1BW·day-1)摄入量显着增加(p<0.001)CON组。此外,INT组实施营养周期化措施,因为在MD-1(7.0±1.7g·kg-1BM·day-1)上CHO的摄入量显着增加,MD(7.1±1.4g·kg-1BM·day-1)和MD1(5.1±0.8g·kg-1BM·day-1)。然而,CON组没有定期补充CHO的摄入量,也没有达到CHO关于MD-1,MD,和MD+1(<4g·kg-1BM·day-1)。与MD-1相比,两组在MD1和MD2上的RMR均增加,尽管仅在INT组中具有统计学意义(MD1=243kcal·day-1;MD2=179kcal·day-1)。
    实施有针对性的营养教育和行为改变干预措施改善了职业足球运动员的饮食习惯,并使他们能够更好地遵守推荐指南。然而,尽管如此,在比赛结束后的24-48小时内,RMR仍然升高。因此,为了优化回收,这一发现进一步加强了职业足球运动员采取满足能量的策略的必要性,尤其是CHO,比赛后的急性期要求,以解决能源需求的增加。
    UNASSIGNED: The importance of nutrition in optimizing the health and performance of professional soccer players has been well established. Despite published practical recommendations for the dietary requirements for professional soccer players, many players fail to meet these guidelines. Thus, the primary purpose of this study was to assess the impact of targeted nutritional education and behavior change interventions on dietary intake in professional football players. Additionally, previous research within this population has reported elevations in resting metabolic rate (RMR) following match-play. Therefore, a further aim of this study was to examine whether any changes in dietary intake would influence RMR following match-play.
    UNASSIGNED: Twenty players from the professional development phase in an English Premier League club (age: 18.4 ± 1.0 years; body mass: 76.1 ± 6.0 kg; stature: 1.80 ± 0.07 m) were randomly assigned to an \"Intervention\" (INT) group (n = 10), who received numerous nutritional education and behavior change interventions, or a \"Control\" (CON) group (n = 10), who received no nutrition support. Dietary intake was assessed daily throughout the match-week (Match Day (MD)-2, MD-1, MD, MD + 1, and MD + 2), whilst RMR was assessed on MD-1, MD + 1, and MD + 2. Statistical analyses on the intervention effects on dietary intake and RMR were carried out using a two factor (group and day) analysis of variance (ANOVA) with a subsequent Bonferroni post-hoc test.
    UNASSIGNED: Mean energy (3393 ± 852 vs. 2572 ± 577 kcal · day-1) and CHO (5.36 ± 1.9 vs. 3.47 ± 1.1 g · kg-1 BW · day-1) intake was significantly higher (p < 0.001) in the INT vs. CON group. Furthermore, the INT group implemented nutrition periodization practices as CHO intake was significantly increased on MD-1 (7.0 ± 1.7 g · kg-1 BM · day-1), MD (7.1 ± 1.4 g · kg-1 BM · day-1) and MD + 1 (5.1 ± 0.8 g · kg-1 BM · day-1). However, the CON group did not periodize their CHO intake and failed to meet the CHO recommendations on MD-1, MD, and MD + 1 (<4 g · kg-1 BM · day-1). Compared to MD-1, the RMR increased on MD + 1 and MD + 2 in both groups, although it was only statistically significant for the INT group (MD + 1 =  +243 kcal · day-1; MD + 2 =  +179 kcal · day-1).
    UNASSIGNED: The implementation of targeted nutritional education and behavior change interventions resulted in improved dietary practices in professional football players and enabled better adherence to recommended guidelines. However, despite this, RMR was still elevated in the 24-48 h following match play. Thus, in order to optimize recovery, this finding further reinforces the need for professional football players to adopt strategies to meet energy, and particularly CHO, requirements in the acute period following a match in order to account for this increase in energy requirement.

    来自可持续来源的饮食是行星健康所必需的,然而,大部分人口,包括育龄女性和儿童,在完全过渡到植物性食品的过程中,将面临无法满足其微量营养素(MN)要求的风险。受约束的饮食优化方法使用数学编程来构建满足预定义参数的饮食,并且可能有助于对满足营养和行星目标的饮食解决方案进行建模。
    审查来自饮食优化研究的证据,提出解决方案,以确保在从可持续来源向饮食过渡的背景下MN的可用性。
    关注过去五年发表的文献的叙事综述。
    使用饮食优化的饮食建模可以设计一系列杂食性和植物性饮食,以满足个体MN要求,减少了对环境的影响,并尽量减少偏离文化上可接受的饮食习惯。利用大规模饮食调查的数据,饮食优化可以支持制定以食物为基础的饮食指南;确定在特定背景下限制MN或限制之间的冲突,例如营养和环境;探索以食物为基础的策略,以增加营养供应,如设防;并支持试验设计。使用的方法和报告的结果是变异性的来源。个体水平的饮食数据和人口亚组(如育龄女性和儿童)的MN要求是重要的要求。虽然保持铁和锌的摄入量经常被报道在可持续来源的饮食中面临挑战,很少有研究考虑生物利用度,随着饮食中植酸盐的增加而减少。必须解决这些和其他数据差距,包括可接受性和可负担性,以提高建模结果在人口建议中的适用性。
    使用饮食优化的饮食模型可用于设计满足MN要求的更可持续饮食,然而,需要将结果转化为饮食干预研究,以测试真实世界在饮食指南中的应用和采用。
    向植物性饮食的广泛转变可能会增加通常来自动物源食品的微量营养素摄入不足的风险。特别是在育龄女性和儿童中。使用饮食优化等技术对个体之间收集的饮食摄入数据进行建模可能有助于指导建议和干预策略;需要将其转化为干预研究。不同人口群体和环境中的代表性数据,结合解决微量营养素生物利用度数据缺口的方法,食物强化,和负担能力,将提高建模结果的适用性。
    UNASSIGNED: Consumption of diets from sustainable sources is required for planetary health, however, large sections of the population, including females of reproductive age and children, will be at risk of not meeting their micronutrient (MN) requirements in a complete transition to plant-based foods. Constrained diet optimization methods use mathematical programming to construct diets that meet predefined parameters and may contribute towards modelling dietary solutions that meet nutritional and planetary targets.
    UNASSIGNED: Review the evidence from diet optimization studies proposing solutions to ensure MN availability in the context of a transition to diets from sustainable sources.
    UNASSIGNED: Narrative review focusing on literature published over the last five years.
    UNASSIGNED: Dietary modelling using diet optimization can design a range of omnivorous and plant-based diets that meet individual MN requirements, have reduced environmental impacts, and minimize deviation from culturally acceptable dietary practices. Using data from large-scale dietary surveys, diet optimization can support development of food-based dietary guidelines; identify limiting MNs in a particular context or a conflict between constraints e.g. nutrition and environment; explore food-based strategies to increase nutrient supply, such as fortification; and support trial design. Methods used and outcomes reported are sources of variability. Individual-level dietary data and MN requirements for population sub-groups such as females of reproductive age and children are important requirements. Although maintaining iron and zinc intakes are regularly reported to present challenges in diets from sustainable sources, few studies have considered bioavailability, which reduces with increased dietary phytate. These and other data gaps including acceptability and affordability must be addressed to improve the applicability of modelling outcomes in population recommendations.
    UNASSIGNED: Dietary modelling using diet optimization can be useful in the design of more sustainable diets that meet MN requirements, however, translation of outcomes into dietary intervention studies is required to test real-world application and adoption into dietary guidelines.
    A widespread shift towards plant-based diets could increase the risk of inadequate intakes of micronutrients typically sourced in foods of animal origin, particularly among females of reproductive age and children.Modelling of dietary intake data collected among individuals using techniques such as diet optimization could be helpful in guiding recommendations and intervention strategies; translation into intervention studies is required.Representative data in different population groups and settings, with methods incorporated to address data gaps on bioavailability of micronutrients, food fortification, and affordability, will improve the applicability of modelling outcomes.

    重症监护是为重症监护病房的患者提供的专门治疗,这些患者患有严重疾病,需要广泛的护理和密切监测。因此进行了本研究。从喀拉拉邦两家著名的多专业三级医院中,总共收集了一百个样本,这些样本在重症监护病房呆了至少五天,印度。APACHEII评分系统,采用DayWorldWide的ICU问卷和格拉斯哥昏迷量表来收集患者的数据,例如个人详细信息,人口统计数据,病史,生物物理参数,生化参数,喂养技术,喂养时间和营养需求。因呼吸衰竭而进入医学ICU的比例约为43%,败血症和其他感染,22%的患者患有神经系统疾病,35%的患者为肾脏病患者。很明显,约79%患有厌食症。将独家商业饲料的管理与商业加厨房饲料的管理进行比较,观察到用后者喂养的患者出现腹痛增加(21%)和呕吐(17%).腹泻在服用商业配方食品的患者中更为常见(12%),而使用厨房饲料喂养的患者便秘较高(19%)。没有确凿的证据支持独家商业饲料或厨房加商业饲料。一小部分(7%)患者的死亡率超过80%。通过肠内喂养系统观察到危重患者的积极结果,独家商业饲料和厨房加商业饲料之间没有显着差异。
    Critical care is the specialized treatment provided to patients in intensive care units who are severely ill and need extensive care and close monitoring. Hence the present study was undertaken. A total of hundred samples were collected exclusively on those who stayed a minimum of five days in Intensive Care Unit from two reputed Multispecialty Tertiary Hospitals from Kerala, India. APACHE II scoring system, Day World Wide\'s ICU Questionnaire and Glasgow Coma Scale were adopted to collect patient\'s data such as personal details, demographic data, medical history, bio-physical parameters, bio- chemical parameters, feeding techniques, time of feeding and nutritional requirements. Admission to Medical ICU were about 43% with respiratory failure, sepsis and other infections, 22% were admitted with neurological diseases and 35% were nephrology patient. It is evident that about 79% were suffering from anorexia. Comparing the administration of exclusive commercial feed to commercial plus kitchen feed, it was observed that patients fed with the latter experienced increased abdominal pain (21%) and vomiting (17%). Diarrhea was more common in patients fed with commercial formula (12%), while constipation was higher in patients fed with kitchen feed (19%). There is no conclusive evidence favoring either exclusive commercial feed or kitchen plus commercial feed. A small percentage (7%) of patients had a mortality rate exceeding 80%. Positive outcomes were observed in critically ill patients through the enteral feeding system, with no significant difference between exclusive commercial feed and kitchen plus commercial feed.

    运动员的特点是特殊的营养需求。满足与高强度运动相关的饮食需求是有效训练和体育比赛成功的先决条件。因此,重要的是提供关键的营养,如大量营养素,抗氧化剂,钙,维生素D,或者铁,足够的数量。对这些营养素的需求增加使得有必要在市场上寻找更充分满足这些需求的食品。此类产品可包括有机食品。根据研究,它们具有独特的特性,富含精选的营养素,如抗氧化剂。因此,本综述的目的是分析现有文献,以了解与常规生产的食品相比,有机食品是否有可能更全面地涵盖运动员对选定营养素的营养需求增加。对当前文献进行了叙述性回顾。正如分析显示的那样,有机食品的特点是抗氧化生物活性化合物含量较高,n-3脂肪酸含量较高,更好的n:3/n:6比例,和更理想的氨基酸组成,这可能会导致运动员适当的膳食配给设计。总之,有机食品似乎是一种有趣的替代品,可以满足专业和业余运动员的特殊营养需求。
    Athletes are characterized by special nutritional needs. Meeting their dietary needs associated with intensive exercise is a prerequisite for effective training and success in sports competitions. Hence, it is important to supply key performance nutrients, such as macronutrients, antioxidants, calcium, vitamin D, or iron, in adequate quantities. The increased need for these nutrients makes it necessary to look for food products on the market that more fully cover these needs. Such products may include organic foods. According to research, they have unique properties and are richer in selected nutrients, such as antioxidants. Hence, the aim of this review was to analyze the available literature as to whether organic foods have the potential to more fully cover the increased nutritional requirements of athletes for selected nutrients compared to conventionally produced foods. A narrative review of current literature was carried out. As the analysis showed, organic foods are characterized by a higher content of antioxidant bioactive compounds, a higher content of n-3 fatty acids, a better n:3/n:6 ratio, and a more optimal amino acid composition, which may result in an appropriate dietary ration design for athletes. In conclusion, organic food appears to be an interesting alternative to meet the special nutritional needs of professional and amateur athletes.

    营养是物种进化的限制特征。营养需求的差异是对环境变化不同适应的进化结果,解释他们生态特征的差异。稻长形虫和稻长形虫,两种相关的稻种,具有相似的形态和摄食特性,但迁移和越冬行为不同。然而,目前尚不清楚它们是否已经进化成成人营养分化特征共存。为了探讨这个问题,这项研究检查了碳水化合物和氨基酸对其生殖和人口统计学参数的影响。研究结果表明,碳水化合物的摄入延长了两个稻米的寿命和种群增长,但氨基酸的摄入只能促进卵的孵化。然而,营养缺乏使得C.medinalis无法成功繁殖和生存,但对C.exigua没有影响.游走性C.medinalis的种群扩展和存活依赖于成人的营养摄入。相反,C.exigua越冬活动所需的营养主要来自幼虫的储存。两种水稻粗提者对种群生长和生存的营养需求差异部分解释了它们在迁移和越冬方面的差异。
    Nutrition is a limiting feature of species evolution. The differences in nutritional requirements are the evolutionary result of differential adaptations to environmental changes, explaining differences in their ecological traits. Cnaphalocrocis medinalis and Cnaphalocrocis exigua, two related species of rice leaffolders, have similar morphology and feeding properties but different migration and overwintering behaviors. However, it is unclear whether they have evolved adult nutritional differentiation traits to coexist. To explore this issue, this study examined the effects of carbohydrates and amino acids on their reproductive and demographic parameters. The findings indicate that carbohydrate intake prolonged the longevity and population growth of two rice leaffolders, but amino acid intake promoted egg hatching only. However, nutrient deficiency made it impossible for C. medinalis to reproduce successfully and survive, but it did not affect C. exigua. The population expansion and survival of migratory C. medinalis relied on adult nutritional intake. Conversely, the nutrients necessary for C. exigua overwintering activity mostly came from the storage of larvae. The difference in nutritional requirements for population growth and survival between the two rice leaffolders partially explained their differences in migration and overwintering.

    确定微生物的营养需求和生长条件对于确定其在工业中的适用性和了解其在临床生态学中的作用至关重要。由于捕食性细菌如Bdellovibrio细菌的自然杀伤特征,它们已经成为对抗人类细菌病原体感染的有希望的工具。Bdellovibrio的生命周期发生在猎物细胞内,利用细胞质作为营养和能量的来源。然而,这个生命周期是一个挑战,当确定从猎物中摄取的代谢物来完成细胞内的生长时,一个尚未完全阐明的过程。这里,遵循基于模型的方法,我们阐明了细菌芽孢杆菌复制DNA的能力,增加生物量,在没有猎物的情况下,在基于氨基酸的富培养基中产生三磷酸腺苷(ATP),保持完整的掠夺性能力。在这种文化中,我们确定了使用的主要碳源及其偏好,是谷氨酸,丝氨酸,天冬氨酸,异亮氨酸,还有苏氨酸.这项研究为掠夺性细菌在自然环境中的作用提供了新的见解,并为使用适当的代谢和生理方法开发新的Bdellovibrio应用奠定了基础。关键点:•氨基酸支持Bdellovibrio细菌的无菌生活方式。•B.细菌在没有猎物的情况下生长时保持其捕食能力。
    Identifying the nutritional requirements and growth conditions of microorganisms is crucial for determining their applicability in industry and understanding their role in clinical ecology. Predatory bacteria such as Bdellovibrio bacteriovorus have emerged as promising tools for combating infections by human bacterial pathogens due to their natural killing features. Bdellovibrio\'s lifecycle occurs inside prey cells, using the cytoplasm as a source of nutrients and energy. However, this lifecycle supposes a challenge when determining the specific uptake of metabolites from the prey to complete the growth inside cells, a process that has not been completely elucidated. Here, following a model-based approach, we illuminate the ability of B. bacteriovorus to replicate DNA, increase biomass, and generate adenosine triphosphate (ATP) in an amino acid-based rich media in the absence of prey, keeping intact its predatory capacity. In this culture, we determined the main carbon sources used and their preference, being glutamate, serine, aspartate, isoleucine, and threonine. This study offers new insights into the role of predatory bacteria in natural environments and establishes the basis for developing new Bdellovibrio applications using appropriate metabolic and physiological methodologies. KEY POINTS: • Amino acids support axenic lifestyle of Bdellovibrio bacteriovorus. • B. bacteriovorus preserves its predatory ability when growing in the absence of prey.

    Prader-Willi综合征(PWS)是一种罕见的疾病,其特征是在整个生命周期中发生不同的营养阶段,从失败到茁壮成长到饮食过度。如果不受控制,能量摄入和消耗之间的不平衡导致肥胖的发展以及发病率和死亡率的增加.尽管准确的营养评估所需能量的措施至关重要,证据显得稀疏和异质;因此,这篇综述的目的是研究可用的文献,在PWS患者中使用各种方法预测或测量能量消耗。寻求提供有关静息能量消耗或基础代谢率的方法和结果的研究。完成了叙述性综合,以介绍研究特征和结果。确定能量需求的方法包括预测方程和间接量热法。年龄之间的差异,生长激素治疗,空腹状态,以及提出结果的措施限制了适当总结和确定能源支出趋势。间接量热法被认为是最准确的方法;然而,它并非在所有设置中广泛可用。鼓励进一步的研究,以支持有效和可靠的预测方程的发展,这将更好地告知和提高临床实践的效率,支持PWS的人。
    Prader-Willi syndrome (PWS) is a rare disorder characterised by varying nutritional phases that occur throughout the lifespan, ranging from failure to thrive to hyperphagia. If uncontrolled, the imbalance between energy intake and expenditure results in obesity development and increased morbidity and mortality risk. Although measures of energy requirements for accurate nutrition assessment are vital, the evidence appears sparse and heterogeneous; hence, the aim of this review was to examine the available literature on energy expenditure predicted or measured using various methods in individuals with PWS. Studies were sought that presented methods and results on resting energy expenditure or basal metabolic rate. A narrative synthesis was completed to present the study characteristics and results. Methods of determining energy requirements included predictive equations and indirect calorimetry. Differences amongst ages, growth hormone therapy, fasting status, and measures in which results were presented were limitations to appropriately summarising and identifying trends in energy expenditure. Indirect calorimetry was identified as the most accurate method; however, it is not widely available in all settings. Further research is encouraged to support the development of valid and reliable predictive equations that will better inform and improve the efficiency of clinical practice in supporting people with PWS.

    为了减少微量营养素缺乏,塞内加尔要求用维生素A和小麦粉加铁和叶酸强化精制油。扩大塞内加尔的大规模食品强化计划,包括强化肉汤,可以帮助填补膳食微量营养素需求方面的剩余缺口。使用2018年至2019年收集的7天家庭食物消费数据,我们评估了维生素A强化肉汤(40-250μg/g肉汤)的潜在贡献。叶酸(20-120μg/g),维生素B12(0.2-2μg/g),铁(0.6-5毫克/克),和锌(0.6-5mg/g),以满足育龄妇女(WRA;15-49岁)和儿童(6-59个月大)的微量营养素需求。大多数家庭(90%)报告说吃肉汤,包括贫困家庭和农村家庭。在建模的防御工事级别,肉汤强化将全国维生素A不足的患病率降低了20个百分点(pp),叶酸34页(WRA)和20页(儿童),维生素B12为20页,锌为38页(WRA)和30页(儿童),和~8页的铁。预计穷人和农村人口的不足减少通常更大,特别是维生素A和B12。我们的模型表明,肉汤强化有可能大大减少多种微量营养素的饮食不足,也可能有助于解决塞内加尔饮食微量营养素不足的不平等问题。
    To reduce micronutrient deficiencies, Senegal mandates the fortification of refined oil with vitamin A and wheat flour with iron and folic acid. Expanding Senegal\'s large-scale food fortification programs to include fortified bouillon could help fill the remaining gaps in dietary micronutrient requirements. Using 7-day household food consumption data collected between 2018 and 2019, we assessed the potential contributions of bouillon fortified with vitamin A (40-250 μg/g bouillon), folic acid (20-120 μg/g), vitamin B12 (0.2-2 μg/g), iron (0.6-5 mg/g), and zinc (0.6-5 mg/g) for meeting micronutrient requirements of women of reproductive age (WRA; 15-49 years old) and children (6-59 months old). Most households (90%) reported consuming bouillon, including poor and rural households. At modeled fortification levels, bouillon fortification reduced the national prevalence of inadequacy by up to ∼20 percentage points (pp) for vitamin A, 34 pp (WRA) and 20 pp (children) for folate, 20 pp for vitamin B12, 38 pp (WRA) and 30 pp (children) for zinc, and ∼8 pp for iron. Predicted reductions in inadequacy were generally larger among poor and rural populations, especially for vitamins A and B12. Our modeling suggests that bouillon fortification has the potential to substantially reduce dietary inadequacy of multiple micronutrients and could also help address inequities in dietary micronutrient inadequacies in Senegal.

    美式足球运动员遵循传统建议消耗大量动物来源的蛋白质,以最大限度地提高肌肉发育和运动表现。这与饮食指南相反,建议减少肉类摄入量和增加植物性食物的消费,以促进健康和降低慢性病的风险。尚未研究完全基于植物的饮食满足美式足球运动员营养需求的能力。这项建模研究将饮食数据从一个大的队列中进行缩放,这些数据遵循完全基于植物的饮食,以满足职业美式足球运动员的能量需求,以确定蛋白质是否,亮氨酸,和微量营养素需求的身体表现和健康得到满足。坎宁安方程用于估计卡路里需求。然后将来自复临安息日会健康研究2的营养素摄入量缩放到该卡路里水平。蛋白质值范围为1.6-2.2克/千克/天,亮氨酸值范围为3.8-4.1克/餐,每天四餐,因此,达到并超过理论上最大化肌肉质量的水平,肌肉力量,和肌肉蛋白质合成,分别。以植物为基础的饮食规模,以满足职业美式足球运动员的能源需求满足蛋白质,亮氨酸,以及肌肉发育和运动表现所需的微量营养素。这些发现表明,完全基于植物的饮食可以弥合美式足球运动员预防慢性病的饮食建议与运动表现之间的差距。
    American football players consume large quantities of animal-sourced protein in adherence with traditional recommendations to maximize muscle development and athletic performance. This contrasts with dietary guidelines, which recommend reducing meat intake and increasing consumption of plant-based foods to promote health and reduce the risk of chronic disease. The capacity of completely plant-based diets to meet the nutritional needs of American football players has not been studied. This modeling study scaled dietary data from a large cohort following completely plant-based diets to meet the energy requirements of professional American football players to determine whether protein, leucine, and micronutrient needs for physical performance and health were met. The Cunningham equation was used to estimate calorie requirements. Nutrient intakes from the Adventist Health Study 2 were then scaled to this calorie level. Protein values ranged from 1.6-2.2 g/kg/day and leucine values ranged from 3.8-4.1 g/meal at each of four daily meals, therefore meeting and exceeding levels theorized to maximize muscle mass, muscle strength, and muscle protein synthesis, respectively. Plant-based diets scaled to meet the energy needs of professional American football players satisfied protein, leucine, and micronutrient requirements for muscle development and athletic performance. These findings suggest that completely plant-based diets could bridge the gap between dietary recommendations for chronic disease prevention and athletic performance in American football players.

    背景:肺运动康复的有限益处与满足能量和蛋白质需求有关。
    目的:目的是提高膳食摄入量,以满足肺康复计划后的需求并保持变化。
    方法:这项单臂干预研究包括对营养的多学科关注和在五个城市中心进行为期10周的肺运动康复期间进行的三次个人饮食咨询。数据在基线(P0)收集,在干预结束时(P1)和两个城市在干预后三个月(P2)。
    结果:在111名参与者中,(平均年龄70.8(±9))99(89%)完成了康复,包括三个单独的饮食咨询。发现包括体重指数和运动能力在内的身体成分差异很大。蛋白质摄入量从64(±22g)(P0)提高到88(±25g)(P1)(p<0.001),能量摄入量从1676(±505kcal)(P0)提高到1941(±553kcal)(p<0.001)(P1),肌肉质量指数从10.6(±3.2)(P0)提高到10.9(±3.2)(P1)(p=1)的重复次数(六分钟步行试验中的距离从377.2(±131.2m)(P0)提高到404.1(±128.6m)(P1)(p<0.001)。两个城市完成了为期三个月的后续行动。对于那些,饮食改善保持稳定,包括蛋白质的摄入。
    结论:在多专业的努力中包括三次饮食咨询与改善个性化饮食摄入有关,以及身体功能。三个月后,福利几乎保持不变。功能的改进不能完全用改进的摄入量来解释。
    BACKGROUND: Limited benefit of pulmonary exercise rehabilitation has been associated with fulfilment of energy and protein requirements.
    OBJECTIVE: The aim was to enhance dietary intake towards requirements and to maintain changes after a pulmonary rehabilitation program.
    METHODS: This single arm intervention study included multidisciplinary focus on nutrition and three sessions of individual dietary counselling during a 10-week pulmonary exercise rehabilitation in five municipalities centers. Data were collected at baseline (P0), at the end of intervention (P1) and for two municipalities at three months post intervention (P2).
    RESULTS: Of the 111 included participants, (mean age 70.8 (±9)) 99 (89%) completed the rehabilitation including the three individual dietary counselling\'s. A very large variation in body composition including body mass index and exercise abilities was found. Protein intake improved from 64 (±22 g) (P0) to 88 (±25 g) (P1) (p < 0.001) and energy intake from 1676 (±505 kcal) (P0) to 1941 (±553 kcal) (p < 0.001) (P1) and Muscle Mass Index increased from 10.6 (±3.2) (P0) to 10.9 (±3.2) (P1) (p = 0.007); number of 30 s chair stand test improved from 10.9 (±2.8) repetitions (P0) to 14.1 (±4.3) repetitions (P1) (p < 0.001), distance in six-minut walking test improved from 377.2 (±131.2 m) (P0) to 404.1 (±128.6 m) (P1) (p < 0.001). Two municipalities completed the three months follow-up. For those, dietary improvements remained stable, including protein intake.
    CONCLUSIONS: Including three sessions of dietary counselling in a multi-professional effort was associated with improved individualized dietary intake, as well as physical function. Benefits remained almost unchanged after three months. Improvements in function could not be fully explained by improved intakes.
