Background

In remote indigenous Panamanian subsistence farming communities, poor diet, diarrhea, and Ascaris may have seasonally distinct contributions to high rates of stunting in preschool children.

Objectives

This study explored the relative contributions of food, nutrient intakes, and infections (diarrhea and intestinal nematodes) to height-for-age z-scores (HAZ) during a dry and rainy season in Panama’s Comarca Ngäbe-Buglé.

Methods

This prospective community-based study collected sociodemographic and health data from 328, 12‒59-mo-old children in both the dry and rainy seasons. Diets were assessed in nonbreastfeeding children using a food frequency questionnaire and a 24-h recall during both seasons. Bivariate comparisons between stunted and nonstunted children and between the dry and rainy seasons were conducted. Stepwise linear regression models identified associations of sociodemographic status, infections, food groups, and estimated nutrient intakes with HAZ.

Results

The diet characterized as low fat, high sugar was deficient in micronutrients. Food and nutrient intakes were lower in the rainy than the dry season (P < 0.05), and stunted children had fewer servings of dairy than nonstunted children (P < 0.05). The incidence of diarrhea was higher in the rainy season (P < 0.05). Determinants of HAZ differed between dry and rainy seasons. In dry season models (P < 0.0001), HAZ was positively associated with income and fat intake and negatively associated with total sugar intake. In contrast, rainy season models (P < 0.0001) revealed that servings of grains/cereals and fat were positively associated with HAZ, and fruit and total sugar intake and diarrhea were negatively associated with HAZ.

Conclusions

The multifactorial nature of linear growth faltering in these preschool children differed by season. The negative impact of diarrhea emerged only in the rainy season, but the negative impact of sugar intake and the positive impact of fat intake emerged in both seasons.
背景:在偏远的巴拿马土著自给农业社区,不良饮食、腹泻和蛔虫可能是学龄前儿童发育迟缓高发率的不同季节性因素。目的:本研究探讨了巴拿马Comarca Ngäbe-Buglé干旱和雨季期间食物、营养摄入和感染(腹泻和肠道线虫)对身高年龄z分数(HAZ)的相对贡献。方法本前瞻性社区研究收集了328,12 - 59岁儿童在旱季和雨季的社会人口学和健康数据。对非母乳喂养儿童的饮食进行了评估,使用食物频率问卷和两个季节的24小时召回。对发育不良儿童和非发育不良儿童以及旱季和雨季儿童进行了双变量比较。逐步线性回归模型确定了社会人口状况、感染、食物组和估计的营养摄入量与HAZ的关联。结果低脂高糖饮食缺乏微量营养素。丰水期儿童的食物和营养摄取量低于旱季(P < 0.05),发育迟缓儿童的乳制品摄取量低于非发育迟缓儿童(P < 0.05)。雨季腹泻发生率较高(P < 0.05)。旱季和雨季影响热影响区的决定因素不同。在旱季模型中(P < 0.0001), HAZ与收入和脂肪摄入量呈正相关,与总糖摄入量负相关。相比之下,雨季模型(P < 0.0001)显示,谷物/谷物和脂肪的摄入量与HAZ呈正相关,水果和总糖摄入量以及腹泻与HAZ呈负相关。结论学龄前儿童线性生长迟缓的多因素性质因季节而异。腹泻的负面影响仅在雨季出现,但糖摄入的负面影响和脂肪摄入的积极影响在两个季节都出现。

Background

As the global population continues to age, cognitive decline has emerged as a major area of concern. Modifiable lifestyle factors, such as diet, have been associated with the trajectory of brain aging. Dietary patterns such as the Western diet (WD) have been linked to cognitive decline, whereas a Mediterranean diet (MeDi) promotes healthy brain aging.

Objectives

This study aimed to compare the effects of MeDi and WD on gut microbiota and cognitive health in middle-aged rats. Our hypothesis was that the MeDi, when introduced to middle-aged rats, would maintain cognitive health and produce a distinct gut microbiota composition relative to a WD.

Methods

Twelve-month-old male Fischer344 rats were randomly assigned to MeDi, WD, or chow (n = 10/group). After 12 wk, fecal samples were collected for 16S rRNA gene sequencing to assess microbial composition. Animals completed the following neurobehavioral assessments, including Y-maze, Morris Water Maze, and Radial Arm Water Maze. At the end of the study, the hippocampus was analyzed for gene and protein expression related to barrier integrity, glial cell activity, and neuroplasticity.

Results

There were trending differences in cognitive function in MeDi rats relative to WD rats. Rats exhibited distinct diet-dependent microbial phenotypes with 28 differentially abundant bacteria, including Blautia, Clostridia UCG-014, Clostridium innocuum group, Faecalibacterium, and Bifidobacterium. This was accompanied by changes in hippocampal gene expression of glial cell activity, including glial fibrillary acidic protein, ionized calcium binding protein, and triggering receptor expressed on myeloid cells 2. Blood–brain barrier integrity and neuroplasticity were maintained during the short-term dietary intervention.

Conclusions

A longer diet duration may be needed to elicit robust differences in cognitive function driven by the changes in microbiota and neurobiology. This study highlights that a short-term diet introduced in middle age has trending effects on cognitive performance but significantly impacts gut microbiota composition and gene expression of biomarkers of brain health.
随着全球人口持续老龄化,认知能力下降已成为人们关注的一个主要领域。可改变的生活方式因素,如饮食,与大脑衰老的轨迹有关。西方饮食(WD)等饮食模式与认知能力下降有关,而地中海饮食(MeDi)则促进健康的大脑衰老。目的比较中西医结合对中年大鼠肠道菌群和认知健康的影响。我们的假设是,将medii引入中年大鼠时,会保持认知健康,并产生与WD不同的肠道微生物群组成。方法选取12月龄雄性fisher 344大鼠,随机分为3组(n = 10/组)。12周后,收集粪便样本进行16S rRNA基因测序以评估微生物组成。动物完成了以下神经行为评估,包括y形迷宫、Morris水迷宫和径向臂水迷宫。在研究结束时,分析海马中与屏障完整性、胶质细胞活性和神经可塑性相关的基因和蛋白表达。结果与WD大鼠相比,MeDi大鼠的认知功能有趋势差异。大鼠表现出不同的饮食依赖微生物表型,有28种不同数量的细菌,包括蓝梭菌、梭菌UCG-014、无芽梭菌组、粪杆菌和双歧杆菌。这伴随着海马胶质细胞活性基因表达的变化,包括胶质纤维酸性蛋白、离子钙结合蛋白和髓细胞上的触发受体表达2。短期饮食干预维持了血脑屏障的完整性和神经可塑性。结论可能需要更长的饮食时间才能引起由微生物群和神经生物学变化驱动的认知功能的显著差异。该研究强调,中年引入的短期饮食对认知能力有趋势影响,但对肠道微生物群组成和大脑健康生物标志物的基因表达有显著影响。

Background

Gut microbiome diversity and composition have been associated with type 1 diabetes (T1D) onset and progression. These features have not been explored among the growing number of older adults with T1D, including how they may differ by diet.

Objectives

In the present observational study, we investigated differences in gut microbiome diversity and composition across quantiles of high and low macronutrient, fiber, and simple sugar intake.

Methods

We collected observational data on routine diabetes management, diet, and other health indicators from older adults with T1D over 7–9 d, including 2 24-h dietary recall interviews, diabetes technology, and medical record data. Stool samples were collected for gut microbiome characterization using high-throughput sequencing of the 16S ribosomal RNA gene. Gut microbiome characteristics were assessed by Analysis of Compositions of Microbiomes with Bias Correction (ANCOM-BC2), Shannon index, and Bray–Curtis distances.

Results

Among 17 older adults [mean (SD) age 73.5 (6.2) y; diabetes duration: 34.0 (16.0) y, and glycated hemoglobin: 7.0 (0.9) %], increased fat intake was associated with enriched genus Lactococcus, increased fiber intake was associated with enriched genus Hemophilus and unclassified Clostridium within family CAG:508, and increased fructose intake was associated with enrichment of unclassified genus SFMI01 within family Christensenellaceae. Greater carbohydrate intake was associated with depletion of the family Enterobacteriaceae. Microbial diversity differed significantly with greater fiber and fructose intake.

Conclusions

We found statistically significant evidence suggesting that the gut microbiome of older adults with T1D may be modulated by macronutrient, fiber, and fructose intake. Similar trends between fiber intake differences and significantly different microbial community structure have been found in younger populations. Together with the literature, our other findings suggest that macronutrient, fiber, and fructose intakes may impact the gut microbiome differently in older adults with T1D.
肠道微生物群的多样性和组成与1型糖尿病(T1D)的发病和进展有关。这些特征还没有在越来越多的老年T1D患者中进行研究,包括饮食对他们的影响。在本观察性研究中,我们研究了高、低宏量营养素、纤维和单糖摄入的分位数在肠道微生物群多样性和组成上的差异。方法收集7-9 d以上老年T1D患者的常规糖尿病管理、饮食和其他健康指标的观察性数据,包括2次24小时饮食回忆访谈、糖尿病技术和医疗记录数据。收集粪便样本,利用16S核糖体RNA基因的高通量测序进行肠道微生物组鉴定。采用偏差校正微生物组组成分析(ANCOM-BC2)、Shannon指数和Bray-Curtis距离评估肠道微生物组特征。结果17例老年人[平均(SD)年龄73.5 (6.2)y;糖尿病病程:34.0 (16.0)y,糖化血红蛋白:7.0(0.9)%],脂肪摄入量增加与乳球菌属的富集有关,纤维摄入量增加与CAG:508家族的嗜血杆菌属和未分类梭状芽胞杆菌属的富集有关,果糖摄入量增加与Christensenellaceae家族的未分类属SFMI01的富集有关。更多的碳水化合物摄入与肠杆菌科细菌的消耗有关。微生物多样性随着纤维和果糖摄入量的增加而显著不同。结论:我们发现有统计学意义的证据表明,老年T1D患者的肠道微生物群可能受到常量营养素、纤维和果糖摄入的调节。在较年轻的人群中也发现了纤维摄入量差异和显著不同的微生物群落结构之间的类似趋势。结合文献,我们的其他研究结果表明,大量营养素、纤维和果糖的摄入可能会对老年T1D患者的肠道微生物群产生不同的影响。

Current Guidelines on Dietary Protein Intake for Patients with Diabetic Kidney Disease: A Scoping Review 糖尿病肾病患者膳食蛋白质摄入指南:范围综述
IF 3.2 Q2 NUTRITION & DIETETICS Pub Date : 2025-10-01 Epub Date: 2025-09-04 DOI: 10.1016/j.cdnut.2025.107551

Background

International nutritional guidelines vary in their recommendations, as well as in the reporting quality of the underlying evidence. An underreported recommendation in guidelines for people with type II diabetes concerns the optimal protein intake in the case of chronic kidney disease (CKD).

Objectives

In this review, we analyze the protein intake recommendations from worldwide practice guidelines for type II diabetes and CKD.

Methods

We conducted a systematic search in the online databases PubMed, Embase, and Cochrane Database of Systematic Reviews, as well as websites, according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, and up to 31 January, 2023. We included nutritional and clinical practice guidelines on protein intake in patients with type II diabetes and CKD of different stages. We assessed the quality of the guidelines using the instruments Appraisal of Guidelines for Research & Evaluation Instrument (AGREE II) and AGREE Recommendation Excellence. We assessed the quality of the underlying scientific evidence using the evidence pyramid and the level of evidence categorization.

Results

Of 24 included guidelines, 5 met the quality assessment of all instruments. Their evidence was based on an overlapping number of randomized controlled trials (RCTs). Nevertheless, their protein intake recommendations differed, ranging from no restriction to restriction to 0.8 g/kg body weight/d.

Conclusions

The reason for the discrepancy of protein intake recommendations between different guidelines could not be determined conclusively, as the methodology of evidence assessment was often insufficiently reported. More long-term and good-quality RCTs are needed. We recommend the use of rigorous development and quality assessment tools in the development of clinical practice guidelines for patients with CKD and type II diabetes.
背景:国际营养指南的建议和基础证据的报告质量各不相同。在2型糖尿病患者指南中,关于慢性肾病(CKD)患者的最佳蛋白质摄入量的建议被低估了。目的在这篇综述中,我们分析了世界范围内II型糖尿病和CKD实践指南中推荐的蛋白质摄入量。方法我们根据系统评价和meta分析指南的首选报告项目,系统检索PubMed、Embase和Cochrane系统评价数据库以及网站,检索时间截止到2023年1月31日。我们纳入了不同阶段II型糖尿病和CKD患者蛋白质摄入的营养和临床实践指南。我们使用研究指南评估工具和评估工具(AGREE II)和卓越推荐工具来评估指南的质量。我们使用证据金字塔和证据分类水平来评估基础科学证据的质量。结果24个纳入的指南中,有5个符合所有工具的质量评价。他们的证据是基于重叠数量的随机对照试验(rct)。然而,他们的蛋白质摄入量建议不同,从不限制到限制到0.8 g/kg体重/d。结论不同指南之间蛋白质摄入量建议存在差异的原因无法确定,证据评估方法的报道往往不够充分。需要更多长期和高质量的随机对照试验。我们建议在CKD和II型糖尿病患者临床实践指南的制定中使用严格的开发和质量评估工具。

A Hitchhiker Story? Exploring HDL as an Overlooked Vitamin D Carrier 《搭便车的故事》?探索HDL作为一种被忽视的维生素D载体
IF 3.2 Q2 NUTRITION & DIETETICS Pub Date : 2025-10-01 Epub Date: 2025-06-30 DOI: 10.1016/j.cdnut.2025.107499

Background

Twenty-five-hydroxyvitamin D, used to assess vitamin status, is the primary circulating form of vitamin D having a half-life measured in weeks, and 1,25-dihydroxyvitamin D is the active metabolite having a half-life measured in hours. Although there has been a preponderance of research on the roles of the active metabolite in health, there remains a limited understanding of the transport of the true vitamin forms, ergocalciferol and cholecalciferol.

Objective

This study proposes an alternative mechanism for vitamin D transport, hypothesizing that high-density lipoprotein (HDL) facilitates its movement from the intestine to the liver using cholesterol transporters.

Methods

This perspective challenges the sole reliance on the classical chylomicron pathway, proposing an alternative mechanism based on vitamin D's striking structural similarity to cholesterol. Both are steroids sharing key features, suggesting analogous intestinal absorption and transport routes. Evidence indicates vitamin D utilizes known enteric cholesterol transporters for uptake. We hypothesize that high-density lipoprotein (HDL) functions as an important interorgan carrier, facilitating vitamin D's movement from the intestine to the liver, using shared cholesterol transporters. This proposed HDL-mediated delivery is particularly relevant given vitamin D-binding protein's lower affinity for vitamin D compared with 25-hydroxyvitamin D.

Results

This mechanism offers a plausible explanation for observed correlations between vitamin D status (plasma 25-hydroxyvitamin D concentrations) and factors affecting HDL cholesterol concentration (HDLc). Modulators that increase HDLc (e.g., fibrates, oral contraceptives, and exercise) are associated with improved vitamin D status, whereas those that decrease HDLc or inhibit vitamin D absorption (e.g., smoking and ezetimibe) are linked to lower vitamin D status. Although current human data are largely correlative and confounded by numerous factors affecting vitamin D status, the consistent associations warrant further investigation into vitamin D’s precise trafficking among lipoprotein fractions.

Conclusions

Re-evaluating vitamin D’s absorption and transport to include a role for HDL holds implications for optimizing vitamin D status.
用于评估维生素状态的25-羟基维生素D是维生素D的主要循环形式,其半衰期以周为单位,而1,25-二羟基维生素D是活性代谢物,其半衰期以小时为单位。尽管对活性代谢物在健康中的作用已经有了大量的研究,但对真正的维生素形式麦角钙化醇和胆钙化醇的运输仍然了解有限。本研究提出了维生素D运输的另一种机制,假设高密度脂蛋白(HDL)通过胆固醇转运体促进其从肠道到肝脏的运动。这一观点挑战了对传统乳糜微粒途径的唯一依赖,提出了一种基于维生素D与胆固醇惊人的结构相似性的替代机制。这两种类固醇具有相同的关键特征,表明类似的肠道吸收和运输途径。有证据表明维生素D利用已知的肠内胆固醇转运体来吸收。我们假设高密度脂蛋白(HDL)作为重要的器官间载体,通过共享胆固醇转运体促进维生素D从肠道到肝脏的运动。与25-羟基维生素D相比,维生素D结合蛋白对维生素D的亲和力较低,因此提出的HDL介导的递送尤其相关。结果,这一机制为观察到的维生素D状态(血浆25-羟基维生素D浓度)与HDL胆固醇浓度(HDLc)影响因素之间的相关性提供了合理的解释。增加HDLc的调节剂(如贝特类、口服避孕药和运动)与改善维生素D状态有关,而减少HDLc或抑制维生素D吸收的调节剂(如吸烟和依折麦布)与降低维生素D状态有关。尽管目前的人体数据在很大程度上与影响维生素D状态的许多因素相关,但这种一致的关联值得进一步研究维生素D在脂蛋白组分中的精确运输。重新评估维生素D的吸收和运输,包括HDL的作用,对优化维生素D状态具有重要意义。

Effect of Dietary Fiber Intake on Chronic Low-Grade Inflammation in Children and Adolescents: A Systematic Review and Meta-analysis of Randomized Controlled Trials 膳食纤维摄入对儿童和青少年慢性低度炎症的影响:随机对照试验的系统回顾和荟萃分析
IF 3.2 Q2 NUTRITION & DIETETICS Pub Date : 2025-09-01 Epub Date: 2025-07-24 DOI: 10.1016/j.cdnut.2025.107511

Previous research suggests that dietary fiber (DF) intake may help reduce chronic low-grade inflammation (CLGI), a condition linked to the early development of cardiometabolic risk factors. Childhood and adolescence represent critical periods for preventing noncommunicable diseases, when adopting healthy eating habits, including adequate fiber consumption, could effectively control CLGI. However, the evidence on DF’s impact on CLGI in the pediatric population remains inconsistent and has not been comprehensively reviewed in a single article. Therefore, we aimed to conduct a systematic review and meta-analysis to assess the effect of DF intake on CLGI in children and adolescents. A systematic search was performed in 4 databases up to January 2025. Two reviewers screened 2030 studies based on inclusion criteria: randomized controlled trials involving participants ≤18 y, interventions (Is) with any type of DF (supplementation, fiber-rich foods, or fiber intake advice) and reporting serum CLGI markers, including C-reactive protein (CRP), interleukin (IL)-6 and TNF-α, among others. Twenty-five randomized controlled trials were included in the systematic review, which showed that DF may have beneficial effects on CRP, IL-10, adiponectin, IL-1β, and IL-6 concentrations; though findings were inconsistent, with some studies reporting no significant changes. Meta-analysis was conducted for CRP, IL-6, and TNF-α. Meta-analysis for CRP concentrations included 10 studies and revealed a significant decrease following DF Is compared to controls (mean difference: –0.640; 95% CI: –1.075, –0.204). Meta-regression revealed that Is based on fiber supplementation resulted in significantly greater CRP reductions compared to those involving fiber-rich foods. Meta-analysis for IL-6 and TNF-α concentrations showed no significant effect after DF I. In conclusion, this review provides evidence that fiber Is may have a beneficial impact on certain markers of CLGI in children and adolescents, particularly by reducing serum CRP concentrations. However, the findings also reveal inconsistencies in the effects of fiber intake on other inflammatory markers.

先前的研究表明,膳食纤维(DF)的摄入可能有助于减少慢性低度炎症(CLGI),这是一种与心脏代谢风险因素的早期发展有关的疾病。儿童期和青春期是预防非传染性疾病的关键时期,此时养成健康的饮食习惯,包括摄入充足的纤维,可以有效控制CLGI。然而,关于DF对儿童CLGI影响的证据仍然不一致,并且尚未在一篇文章中进行全面审查。因此,我们旨在进行系统回顾和荟萃分析,以评估DF摄入量对儿童和青少年CLGI的影响。系统检索4个数据库,截止到2025年1月。两名评审人员根据纳入标准筛选了2030项研究:随机对照试验,受试者≤18岁,干预措施(i)采用任何类型的DF(补充剂、富含纤维的食物或纤维摄入建议),并报告血清CLGI标志物,包括c反应蛋白(CRP)、白细胞介素(IL)-6和TNF-α等。系统评价纳入了25个随机对照试验,结果显示DF可能对CRP、IL-10、脂联素、IL-1β和IL-6浓度有有益影响;尽管研究结果不一致,一些研究报告没有明显的变化。对CRP、IL-6和TNF-α进行meta分析。荟萃分析包括10项研究,结果显示,与对照组相比,DF后CRP浓度显著降低(平均差异:-0.640;95% CI: -1.075, -0.204)。荟萃回归显示,与富含纤维的食物相比,以补充纤维为基础的饮食显著降低了CRP。对IL-6和TNF-α浓度的荟萃分析显示,在DF i后,IL-6和TNF-α浓度没有显著影响。总之,本综述提供的证据表明,纤维Is可能对儿童和青少年CLGI的某些标志物有有益的影响,特别是通过降低血清CRP浓度。然而,研究结果也揭示了纤维摄入对其他炎症标志物的影响不一致。该试验在普洛斯彼罗注册为CRD42024516794。

Meat Consumption in Relation to Colorectal Cancer Incidence in Anatomical Subsites in the National Institutes of Health-AARP Diet and Health Study 美国国立卫生研究院aarp饮食与健康研究中肉类消费与结直肠癌发病率解剖亚位的关系
IF 3.2 Q2 NUTRITION & DIETETICS Pub Date : 2025-09-01 Epub Date: 2025-08-29 DOI: 10.1016/j.cdnut.2025.107540

Background

In the literature, the consumption of red and processed meat is associated with colorectal cancer (CRC) incidence. It still remains unclear whether the associations of different types of meat intake with CRC vary by subsite of the colorectum.

Objectives

We investigated the association of red, white, and processed meat intakes with CRC incidence across anatomical subsites of the colon and rectum.

Methods

We analyzed data from 454,505 cancer-free adults in the National Institutes of Health-AARP Diet and Health Study cohort. During 6,896,619 person-years of follow-up, 9,461 CRC cases were diagnosed. Type and amount of meat consumed were assessed via food frequency questionnaire. Cox proportional hazards models were used to estimate associations of meat intake, by type, with CRC for an estimated fixed-unit measure of 50 g/1000 kcal, applying both a substitution and addition approach. The substitution model estimated the effect of replacing a given meat type with another type while keeping total meat constant. The addition model evaluated the independent effects of each meat type, keeping all other individual meat types, but not total meat, constant.

Results

Replacing 50 g/1000 kcal of white meat with red meat was associated with 21% higher CRC incidence. Higher incidence was also observed for proximal colon (16%), distal colon (25%), and rectal (30%) cancers, driven by positive associations in the cecum (19%), transverse colon (32%), sigmoid colon (28%), and rectosigmoid junction (65%). Every 50 g/1000 kcal of red meat intake was independently associated with higher CRC incidence in the proximal colon (11%), distal colon (22%), and rectum (19%). However, white meat was only associated with a lower incidence when replacing red meat. Replacing unprocessed with processed meat intake was associated with higher CRC incidence overall (15%), namely in the proximal colon (18%) and the cecum (33%). Processed meat intake was also independently associated with higher CRC incidence.

Conclusions

We found that replacing white meat with red meat was associated with higher CRC incidence. The lack of independent inverse associations for white meat intake indicates that lower CRC incidence is derived from lower red meat intake.
在文献中,食用红肉和加工肉与结直肠癌(CRC)的发病率有关。目前尚不清楚不同类型的肉类摄入与结直肠癌的关系是否因结直肠亚区而异。目的研究红肉、白肉和加工肉摄入量与结肠和直肠解剖亚位结直肠癌发病率的关系。方法:我们分析了来自美国国立卫生研究院aarp饮食与健康研究队列的454,505名无癌成年人的数据。在6896619人年的随访中,9461例结直肠癌被确诊。通过食物频率问卷对肉类的种类和数量进行评估。Cox比例风险模型用于估计肉类摄入类型与CRC的关联,估计固定单位测量为50 g/1000 kcal,同时采用替代和添加方法。替代模型估计了在保持肉类总量不变的情况下,用另一种肉类替代一种特定肉类的效果。添加模型评估了每种肉类类型的独立效应,保持所有其他单个肉类类型不变,但不保持总肉类不变。结果用红肉代替50 g/1000 kcal的白肉可使结直肠癌发病率提高21%。近端结肠(16%)、远端结肠(25%)和直肠(30%)癌症的发病率也较高,盲肠(19%)、横结肠(32%)、乙状结肠(28%)和直肠-乙状结肠交界处(65%)的正相关。每摄入50克/1000千卡的红肉与近端结肠(11%)、远端结肠(22%)和直肠(19%)较高的结直肠癌发病率独立相关。然而,当取代红肉时,白肉的发病率较低。用加工肉类替代未加工肉类的摄入,总体上CRC发病率更高(15%),即近端结肠(18%)和盲肠(33%)。加工肉类的摄入也与较高的结直肠癌发病率独立相关。结论我们发现用红肉代替白肉与更高的CRC发病率相关。白肉摄入量缺乏独立的负相关表明,较低的CRC发病率源于较低的红肉摄入量。

Empowering Young Adults as Agents of Household Dietary Change: Findings From a Pilot Study Involving a Digital, Family-Led Sodium Reduction Intervention in Singapore 授权年轻人作为家庭饮食改变的推动者:来自新加坡一项涉及数字、家庭主导的减钠干预的试点研究的结果
IF 3.2 Q2 NUTRITION & DIETETICS Pub Date : 2025-09-01 Epub Date: 2025-08-05 DOI: 10.1016/j.cdnut.2025.107523

Background

Unhealthy dietary habits such as high-sodium intake, are socially embedded and often resistant to individual-level interventions. Family-led approaches, where 1 member initiates change within the household, may offer a more effective alternative.

Objectives

This pilot study assessed the feasibility and preliminary impact of a digitally delivered, young adult-led sodium reduction intervention on household-level knowledge, attitudes, and behaviors in Singapore.

Methods

In a pre-post, single-group design, young adults completed a co-created, self-paced online course featuring video lessons, interactive assignments, and personalized feedback. Over 2 weeks, participants developed sodium-reduction goals and implemented them through tailored 4-wk action plans. Weekly reflections and course metadata captured goal progress, effort, strategies, and barriers. Family members completed parallel preintervention and postintervention surveys, although they did not receive the intervention directly. Surveys assessed constructs from the Theory of Planned Behavior. Multivariable linear mixed models evaluated changes over time, adjusting for demographic and health characteristics.

Results

Overall, 35 young adults (mean age: 24.4 y; standard deviation [SD]: 3.1) and 79 family members (mean age: 43.0 y; SD: 15.5) completed the intervention. Young adults took a mean of 7.7 d to complete the course, with most crafted goals focusing on reducing sodium intake when eating out. Participants reported higher effort and success with personal goals than family-oriented ones. Perceived behavioral control showed the greatest improvement among both young adults (+2.64, 95% confidence interval [95% CI]: 2.05, 3.22) and family members (+1.82, 95% CI: 1.42, 2.22). Significant gains were also observed in knowledge, behaviors, subjective norms, and behavioral intentions for all participants (all P < 0.001). Engagement metrics (e.g., time spent on the course, effort put into the action plans) were not associated with differential changes in most outcomes.

Conclusions

A young adult-led, family-focused digital intervention was feasible and demonstrated preliminary improvements in household sodium-related outcomes, warranting further evaluation in larger, more diverse populations.
健康的饮食习惯,如高钠摄入量,是社会根深蒂固的,往往难以通过个人层面的干预。家庭主导的方法,即由一个成员在家庭内部发起变革,可能是一种更有效的选择。目的:本试点研究评估了新加坡年轻人主导的数字化减钠干预对家庭层面知识、态度和行为的可行性和初步影响。方法:在一项发布前的单组设计中,年轻人完成了一个共同创建的、自定进度的在线课程,该课程包括视频课程、互动作业和个性化反馈。在两周的时间里,参与者制定了减少钠的目标,并通过量身定制的4周行动计划来实施这些目标。每周反思和课程元数据捕获目标进展、努力、策略和障碍。家庭成员完成了平行的干预前和干预后调查,尽管他们没有直接接受干预。调查评估了计划行为理论的构念。多变量线性混合模型评估了随时间的变化,调整了人口统计学和健康特征。结果共有35名年轻人(平均年龄24.4岁,标准差[SD]: 3.1)和79名家庭成员(平均年龄43.0岁,SD: 15.5)完成了干预。年轻人平均花了7.7天的时间来完成这个课程,大多数精心设计的目标都集中在减少外出就餐时的钠摄入量。参与者报告说,与以家庭为中心的目标相比,他们在个人目标上付出了更多的努力,取得了更大的成功。感知行为控制在年轻人(+2.64,95%可信区间[95% CI]: 2.05, 3.22)和家庭成员(+1.82,95% CI: 1.42, 2.22)中表现出最大的改善。在所有参与者的知识、行为、主观规范和行为意图方面也观察到显著的增益(P均为0.001)。参与指标(例如,在课程上花费的时间,投入行动计划的努力)与大多数结果的差异变化无关。结论:以年轻人为主导、以家庭为中心的数字干预是可行的,并显示出家庭钠相关结果的初步改善,需要在更大、更多样化的人群中进行进一步评估。
