Background

The longitudinal trajectory of body mass index (BMI) and brain structure development during peri-adolescence is not clearly defined in offspring prenatally exposed to gestational diabetes mellitus (GDM) versus unexposed offspring.

Methods

Participants between age 9 and 10 years (N = 9583) were included from the Adolescent Brain and Cognitive Development (ABCD) Study and followed yearly through 4-year follow-up. GDM and puberty status were self-reported. BMI was calculated yearly, and MRI assessed brain structure biennially. Mixed-effects models analysed trajectories of BMI and brain structural measures between groups controlling for sociodemographic covariates, and linear spline was defined with a knot at the onset of puberty.

Results

There was an interaction of exposure by age in change in BMI [β (95% CI) = 0.032 (0.008, 0.056), p = 0.009] and mean cortical thickness [β (95% CI) = −0.038 (−0.071, −0.004), p = 0.027]. The former was driven by greater pre-pubertal increases in BMI [β (95% CI) = 0.051 (0.002, 0.100), p = 0.043], whereas the latter was driven by faster post-pubertal declines in cortical thickness among GDM-exposed offspring [β (95% CI) = −0.051 (−0.095, −0.007), p = 0.046].

Conclusion

Prenatal GDM exposure is associated with greater pre-pubertal increases in BMI and faster post-pubertal cortical thinning in youth aged between 9 and 15.

背景：产前暴露于妊娠期糖尿病（GDM）的后代与未暴露于妊娠期糖尿病（GDM）的后代在青春期前后身体质量指数（BMI）和大脑结构发育的纵向轨迹尚不清楚。方法：从青少年大脑和认知发展（ABCD）研究中纳入年龄在9至10岁之间的参与者（N = 9583），每年随访4年。GDM和青春期状态均为自我报告。BMI每年计算一次，MRI每两年评估一次脑结构。混合效应模型分析了控制社会人口协变量的组间BMI和脑结构测量的轨迹，线性样条被定义为青春期开始时的一个结。结果：暴露与年龄之间存在交互作用，影响BMI [β (95% CI) = 0.032 (0.008, 0.056), p = 0.009]和平均皮质厚度[β (95% CI) = -0.038 (-0.071, -0.004), p = 0.027]。前者是由青春期前较大的BMI增加引起的[β (95% CI) = 0.051 (0.002, 0.100), p = 0.043]，而后者是由gdm暴露后代青春期后皮质厚度下降更快引起的[β (95% CI) = -0.051 (-0.095, -0.007), p = 0.046]。结论：在9 - 15岁的青少年中，产前GDM暴露与青春期前BMI增加和青春期后皮质变薄有关。

U.S. acculturation is associated with poor diet quality and obesity. This study examined the association of acculturation with added sugars among Mexican American adolescents, and whether added sugars mediate the association between acculturation and overweight/obesity. Data from NHANES 2009–2018 included 1317 Mexican American adolescents aged 12–19 years. Acculturation was measured by language spoken at home (English vs. Spanish) and birthplace of child and caregiver (United States vs. Mexico). Added sugars intake was assessed by 24-h dietary recall and categorised as ‘high’ (≥ 10% total energy intake) versus ‘low’ (< 10%). Multivariable logistic regressions tested associations between acculturation and added sugars, and path analysis evaluated the mediation of added sugars between acculturation and overweight/obesity (≥ 85th BMI percentile). Greater acculturation, indicated by primarily speaking English at home (OR: 1.6; 95% CI: 1.0, 2.5), caregiver being U.S.-born (2.2; 1.1, 4.2), both child and caregiver U.S.-born (2.8; 1.2, 6.5), or both U.S.-born + English at home (2.9; 1.1, 7.5), was associated with higher odds of high added sugars intake. Added sugars did not mediate the effect of acculturation on obesity/overweight status. These findings suggest that while higher acculturation is associated with excess added sugars intake, future research is needed to clarify how acculturation influences obesity risk.

背景：与健康体重（HW）相比，超重或肥胖儿童（OW/OB）的认知能力和海马体积较低。这是否适用于有家族性OW/OB风险的HW患儿尚不清楚。目的：比较OW/OB高风险（HR）和低风险（LR） HW儿童的记忆表现和海马亚区体积。方法：HW儿童（n = 95，年龄8-11岁），分为HR组（n = 43，父母双方均患有OW/OB）和LR组（n = 52，父母双方均患有HW），采用结构磁共振成像和记忆测试（言语表学习测试-食物-儿童版（VLLT-Food-C）和儿童记忆量表子测试：单词对、点位置）。线性模型测试各组在记忆评分、海马和子区（CA1、CA3、齿状回（DG）、丘下）体积方面的差异。结果：各组在人口统计学上没有差异，除了身体质量指数（HR > LR, p = 0.003），尽管所有儿童都是高体重。LR儿童在VLLT-Food-C短记忆（β $$ beta $$ = 0.34, p β $$ beta $$ = 0.21, p = 0.04）和单词对延迟回忆（β $$ beta $$ = 0.21, p = 0.04）上表现较好。颅内容积调整后，HR患儿双侧海马全区、CA1、DG、右侧CA3体积减小（ps β $$ beta $$ = 0.15, p = 0.04）。结论：记忆和海马体积的差异可能反映了HW儿童OW/OB的潜在家族风险。

Background

The 2023 Clinical Practice Guideline for pediatric obesity recommends immediate, intensive treatment, including behavioral therapy, medications, and surgery when indicated. Understanding parental agreement with the guideline is critical for successful implementation.

Objective

To evaluate parental awareness of and agreement with the guideline.

Methods

Parents (n = 150; 62.9% female; 75.5% White; M_age = 37.6 ± 7.4 years) completed an online survey assessing guideline awareness and agreement. K-means cluster analysis identified parent subgroups based on agreement patterns. Linear regression examined predictors of agreement (e.g., parent age, BMI). Inductive content analysis explored underlying perspectives.

Results

Few parents (5.3%) were aware of the guideline before the survey. Cluster analysis identified three subgroups: Guideline Skeptics (34%; broadly disagreed), Selective Supporters (28%; mostly agreed but opposed medications and surgery), and Guideline Supporters (38%; broadly agreed). Higher parental BMI predicted lower agreement (β = −0.20, p = 0.018). Qualitative findings added nuance to parents' preference for lifestyle changes, highlighted concerns about mental health and eating disorders, and emphasized parental responsibility in the development and treatment of obesity.

Conclusions

Parental agreement with the guideline varies widely. While most support behavioral treatment, many express concerns about medications and surgery, and a subset of “Guideline Skeptics” reject core principles such as the use of BMI. Tailored implementation strategies are needed to address these diverse views.

背景：2023儿科肥胖临床实践指南建议立即进行强化治疗，包括行为治疗、药物治疗和必要时的手术治疗。理解家长同意指导方针是成功实施的关键。目的：评价家长对该指南的认知度和认同程度。方法：150名家长（女性62.9%，白人75.5%，年龄37.6±7.4岁）完成在线问卷调查，评估家长对指南的认知和认同。K-means聚类分析根据一致性模式确定父子组。线性回归检验了一致性的预测因子（如父母年龄、体重指数）。归纳性内容分析探究了潜在的观点。结果：调查前很少有家长知晓该指南（5.3%）。聚类分析确定了三个亚组：指南怀疑论者（34%；广泛不同意），选择性支持者（28%；大部分同意但反对药物和手术）和指南支持者（38%；广泛同意）。父母BMI越高，一致性越低（β = -0.20, p = 0.018）。定性研究发现，父母对改变生活方式的偏好有细微差别，强调了对心理健康和饮食失调的关注，并强调了父母在肥胖发展和治疗中的责任。结论：家长对指南的认同差异很大。虽然大多数人支持行为治疗，但许多人表达了对药物和手术的担忧，还有一部分“指南怀疑论者”拒绝使用BMI等核心原则。需要量身定制的实施战略来处理这些不同的观点。

Parental communication plays a critical role in weight-related health of children and adolescents and requires a balanced, thoughtful and supportive approach. The European Childhood Obesity Group (ECOG) convened a panel of experts to discuss the topic of parental communication in the prevention and treatment of child and adolescent obesity, as summarised in this statement. Parental concern about weight is evident, but the lack of parental knowledge about obesity, the impact of weight bias and stigma on their children and adolescents' health behaviours, and the influences of culture, media, and advertising all make communication challenging and problematic for many families. Parents need support and skill building in order to provide a communication environment that is healthy and accepting. Healthcare professionals can model healthy communication styles by focusing on health, building family strengths and supports, asking youth about what words they prefer using to discuss their weight, and acknowledging the multifactorial causes of obesity that reside in the socioecological environment. While parental communication offers a powerful platform for promoting healthy behaviours in youth, it must be handled with care to avoid the harms of stigmatisation and oversimplification of obesity as a reflection of individual lifestyle choices. With appropriate tools, knowledge, skills, and support, parents can be better equipped to engage in supportive dialogue that empowers their children and promotes their health and wellbeing.

父母的沟通在儿童和青少年的体重相关健康中起着至关重要的作用，需要一种平衡、周到和支持的方法。欧洲儿童肥胖小组（ECOG）召集了一个专家小组，讨论父母沟通在预防和治疗儿童和青少年肥胖方面的主题，总结在本声明中。父母对体重的关注是显而易见的，但父母对肥胖缺乏了解，体重偏见和污名对儿童和青少年健康行为的影响，以及文化、媒体和广告的影响，都使许多家庭的沟通充满挑战和问题。父母需要支持和技能培养，以提供一个健康和包容的交流环境。医疗保健专业人员可以通过关注健康，建立家庭力量和支持，询问年轻人他们更喜欢用什么词来讨论他们的体重，并承认存在于社会生态环境中的肥胖的多因素原因来塑造健康的沟通方式。虽然父母的沟通为促进青少年的健康行为提供了一个强有力的平台，但必须谨慎处理，以避免将肥胖污名化和过度简化为个人生活方式选择的反映。有了适当的工具、知识、技能和支持，父母就能更好地参与支持性对话，增强孩子的权能，促进他们的健康和福祉。

Background

To prevent the development of obesity and related comorbidities, interventions must begin early in life. This study aimed to assess the impact of a home-based obesity prevention intervention on children's and parents' body mass index (BMI).

Methods

The Guelph Family Health Study is a randomised controlled trial of a 6-month obesity prevention intervention aimed at establishing healthful household routines regarding family meals, children's screen time, physical activity and sleep among 285 families with preschool-aged children. The control group received 6 emails on child health behaviours. The analytic sample included 376 children (3.6 ± 1.3 years old, 20.2% at risk for overweight, 8.2% with overweight/obesity) and 481 parents (58.2% with overweight/obesity).

Results

Compared to controls, the intervention had no significant impact on children's or parents' BMI at post-intervention and 1 year after the intervention. Children in both the intervention and control groups had a non-significant decrease in BMI from baseline to post-intervention [intervention; −0.23 kg/m² (95% CI, −0.46, 0.002); control; −0.17 kg/m² (95% CI, −0.40, 0.06)] and from baseline to 1-year follow-up [intervention, −0.29 kg/m² (95% CI, −0.67, 0.08); control, −0.06 kg/m² (95% CI, −0.42, 0.30)].

Conclusions

Compared to controls, this home-based obesity prevention intervention had no significant impact on children's or parents' BMI immediately after the intervention or after 1 year of follow-up, indicating that the intervention had no additional effect compared to the control group on children's or parents' BMI over time. Future data collection phases will allow for the examination of the intervention effect on BMI as children age.

Background

Adequate sleep duration is a prevention factor for paediatric obesity, but the role of timing is still unclear.

Objectives

To investigate associations of sleep duration and timing with BMI in a large paediatric database.

Methods

Medical chart and survey data were collected from 29 409 children aged 2–18 years who attended well-child visits between Jan 2019 and Dec 2023 (repeated-measures cross-sectional design). Logistic and linear mixed effects regression models accounting for repeated measures estimated odds of overweight/obesity and continuous BMI-for-age CDC-based percentiles for each additional/later hour of sleep duration, midpoint (median of bedtime and wake time), and bedtime, adjusted for potential confounders and stratified by age groups.

Results

Among young children (2–5 years), shorter sleep duration but not sleep timing was related to higher odds of overweight/obesity (21% higher odds with 95% CI: 3% to 36%). In mid-childhood (6–12 years), shorter sleep duration and later midpoint were associated with higher odds of overweight/obesity (18%, 95% CI = 9%, 26%; 32%, 95% CI = 17%, 49%). Among adolescents (13–18 years), each hour of later sleep midpoint equated to 12% higher odds of living with overweight/obesity (95% CI: 1% to 23%). Linear models were similar.

Conclusions

Shorter sleep duration at younger ages and later sleep timing in adolescence were associated with higher BMI.

背景：充足的睡眠时间是预防儿童肥胖的一个因素，但时间的作用尚不清楚。目的：在一个大型儿科数据库中调查睡眠时间和睡眠时间与BMI的关系。方法：收集2019年1月至2023年12月就诊的29 409名2-18岁儿童的病历和调查数据（重复测量横断面设计）。考虑重复测量的Logistic和线性混合效应回归模型估计了超重/肥胖的几率和基于疾病预防控制中心的连续bmi年龄百分位数，每增加/晚睡一小时，中点（就寝时间和清醒时间的中位数）和就寝时间，调整了潜在的混杂因素并按年龄组分层。结果：在幼儿（2-5岁）中，较短的睡眠时间而非睡眠时间与较高的超重/肥胖几率相关（高21%的几率，95% CI: 3%至36%）。在儿童中期（6-12岁），较短的睡眠时间和较晚的睡眠时间与较高的超重/肥胖几率相关（18%,95% CI = 9%, 26%; 32%, 95% CI = 17%, 49%）。在青少年（13-18岁）中，睡眠中点每晚一个小时，超重/肥胖的几率就会增加12%（95%置信区间：1%至23%）。线性模型相似。结论：年轻时较短的睡眠时间和青春期较晚的睡眠时间与较高的BMI有关。

Childhood obesity remains a major global public health challenge, leading to significant short- and long-term adverse health outcomes and imposing substantial societal costs. Recognising the critical importance of early intervention, the Horizon2020 EU-funded JPI Consortium EndObesity has prioritised the first 1000 days of life, from preconception to 2 years of age, as a key window for obesity prevention strategies. This narrative review synthesises findings from the EndObesity Consortium, summarising evidence from large multi-cohort studies on the influence of family-based health behaviours in the first 1000 days on offspring obesity risk, the potential of childhood obesity prediction models in the first 1000 days, and strategies to enhance prenatal and postnatal interventions to prevent childhood obesity development. Finally, we present recommendations for research, practice, and policy to address the complex, multifaceted challenges of childhood obesity prevention in the first 1000 days.

儿童肥胖仍然是一项重大的全球公共卫生挑战，导致严重的短期和长期不良健康后果，并造成巨大的社会成本。意识到早期干预的重要性，欧盟资助的Horizon2020 JPI Consortium endobesobesity将生命的前1000天（从孕前到两岁）作为预防肥胖策略的关键窗口。这篇叙述性综述综合了来自肥胖联盟的研究结果，总结了来自大型多队列研究的证据，这些研究涉及前1000天家庭健康行为对后代肥胖风险的影响，前1000天儿童肥胖预测模型的潜力，以及加强产前和产后干预以预防儿童肥胖发展的策略。最后，我们提出了研究、实践和政策方面的建议，以解决儿童肥胖预防在头1000天面临的复杂、多方面的挑战。

Relative Fat Mass as an Estimator of Abdominal Adiposity in Youth Across the BMI Spectrum from Normal Weight to Obesity 相对脂肪量作为从正常体重到肥胖的BMI谱中青少年腹部肥胖的估计。

IF 2.7 3区医学 Q1 PEDIATRICS

Pediatric Obesity

Pub Date : 2025-10-15 DOI: 10.1111/ijpo.70059

Wonhee Cho, Joon Young Kim, Silva Arslanian

Background

Relative fat mass (RFM) has been used to estimate whole-body fat percentage (%BF). However, whether RFM can mirror abdominal adiposity is unknown.

Objective

In youth, we examined if RFM reflects abdominal adiposity, if there are age/race/sex differences in the relationships between RFM and abdominal adiposity, and if our present-youth-cohort-derived RFM (RFM-Y) improves the prediction of %BF and abdominal adiposity.

Methods

In 358 youth (aged 10–19 years; 168 black/198 white) with normal weight and overweight/obesity (without secondary or syndromic obesity), visceral (VAT), subcutaneous (SAT) and total abdominal adipose tissue (TAT) were assessed by MRI/CT and %BF with DXA. RFM was calculated for ages 10–14 years as [74 − (22 × height/waist circumference [WC]) + (5 × sex)] and 15–19 years as [64 − (20 × height/WC) + (12 × sex)]; sex = 0 for boys, 1 for girls. To develop and validate RFM-Y, linear regression, concordance correlation coefficient, Bland–Altman plots and intraclass correlation coefficient were conducted.

Results

RFM associated with VAT, SAT and TAT (r = 0.66, 0.79, 0.79, respectively; all p < 0.001). The slope was significantly greater in (a) younger versus older youth for VAT, SAT and TAT; (b) whites versus blacks for VAT; and (c) girls versus boys for SAT and TAT. RFM-Y versus traditional RFM showed improved predictive ability for %BF (R ² = 0.83 vs. 0.77) and abdominal adiposity (R ² ranging from 0.51 to 0.80 vs. 0.37 to 0.63).

Conclusions

RFM reflects abdominal adiposity besides %BF and could be used in longitudinal/interventional youth trials, obviating the need for expensive imaging to assess changes in total and abdominal adiposity.

背景：相对脂肪量（RFM）已被用来估计全身脂肪百分比（%BF）。然而，RFM是否能反映腹部肥胖尚不清楚。目的：在年轻人中，我们研究了RFM是否反映了腹部肥胖，RFM和腹部肥胖之间的关系是否存在年龄/种族/性别差异，以及我们现在的青年队列衍生的RFM （RFM- y）是否改善了BF %和腹部肥胖的预测。方法：对358例体重正常、超重/肥胖（无继发性或综合征性肥胖）的青年（10-19岁；黑人168例/白人198例），采用MRI/CT和%BF结合DXA对内脏（VAT）、皮下（SAT）和腹部总脂肪组织（TAT）进行评估。10-14岁的RFM为[74 - (22 ×身高/腰围[WC]) + （5 ×性别）]，15-19岁的RFM为[64 - （20 ×身高/腰围）+ （12 ×性别）]；性别=男孩0，女孩1。采用线性回归、一致性相关系数、Bland-Altman图和类内相关系数等方法对RFM-Y进行开发和验证。结果：RFM与VAT、SAT和TAT （r分别为0.66、0.79、0.79；p均为0.83 vs. 0.77）和腹部肥胖相关（R2为0.51 ~ 0.80 vs. 0.37 ~ 0.63）。结论：RFM除反映BF %外还反映腹部脂肪，可用于纵向/介入性青年试验，无需昂贵的成像来评估总脂肪和腹部脂肪的变化。

Background

Childhood obesity disproportionately affects priority populations, including racial and ethnic minority groups and those with lower socio-economic backgrounds. These groups often encounter barriers to accessing public health services and may benefit from targeted interventions.

Objective

This scoping review aimed to identify the characteristics of populations involved in interventions to prevent early childhood obesity and to understand whether and how existing interventions targeted and reached priority populations.

Methods

Databases and trial registries were systematically searched until 4 October 2024, for planned, ongoing, and completed randomised controlled trials evaluating parent-focussed, behavioural interventions for childhood obesity prevention, starting within the first year of life. Two reviewers independently extracted data using a customised tool.

Results

Of the 11 960 articles identified, 82 trials were eligible. Most trials (87%) were conducted (or planned) in high-income countries, 11% in upper middle-income countries, and 2% in lower middle-income countries. Priority populations included parent–child dyads from specific ethnic or racial groups facing psychological, social, and/or economic disadvantages. Among the completed trials, 54% targeted priority populations, yet only 33% exclusively enrolled participants from these groups. Additionally, less than a quarter of the trials involved priority populations in the design of interventions (17%) and developed tailored interventions for these groups (21%).

Conclusions

Current interventions do not sufficiently target, reach and engage priority populations. To achieve health equity in early childhood obesity prevention, it is essential to include underserved and at-risk populations in research and intervention design.

背景：儿童肥胖不成比例地影响重点人群，包括种族和少数民族群体以及社会经济背景较低的人群。这些群体在获得公共卫生服务方面经常遇到障碍，并可能受益于有针对性的干预措施。目的：本综述旨在确定参与预防早期儿童肥胖干预措施的人群特征，并了解现有干预措施是否以及如何针对并达到重点人群。方法：系统检索数据库和试验注册库，直至2024年10月4日，以评估以父母为中心的儿童肥胖预防行为干预的随机对照试验，从生命的第一年开始，评估正在进行和完成的随机对照试验。两名审稿人使用定制的工具独立提取数据。结果：在11960篇文献中，有82项试验符合条件。大多数试验（87%）在高收入国家进行（或计划进行），11%在中高收入国家，2%在中低收入国家。重点人群包括来自面临心理、社会和/或经济劣势的特定族裔或种族群体的亲子二人组。在已完成的试验中，54%针对的是优先人群，但只有33%的试验只招募了这些人群的参与者。此外，不到四分之一的试验在干预措施设计中涉及优先人群（17%），并为这些群体制定了量身定制的干预措施（21%）。结论：目前的干预措施没有充分瞄准、覆盖和吸引重点人群。为了在儿童早期肥胖预防方面实现健康公平，必须在研究和干预设计中纳入服务不足和高危人群。
