Introduction

Prevalence and risk factors for elevated glycated haemoglobin (HbA1c) and blood pressure (BP) are poorly understood among Pacific children. We examined associations of HbA1c and BP in 6–9 year-olds with body mass index (BMI) at ages 2, 5, and BMI velocity between 2–9 years in Samoa.

Methods

HbA1c (capillary blood) and BP were measured in n = 410 Samoan children who were part of an ongoing cohort study. Multilevel models predicted BMI trajectory characteristics. Generalized linear regressions assessed associations of childhood characteristics and BMI trajectories with HbA1c and BP treated as both continuous and categorical outcomes. Primary caregiver-reported childhood characteristics were used as covariates.

Results

Overall, 12.90% (n = 53) of children had high HbA1c (≥5.7%) and 33.17% (n = 136) had elevated BP. BMI at 5-years and BMI velocity were positively associated with high HbA1c prevalence in males. A 1 kg/m2 per year higher velocity was associated with a 1.71 (95% CI: 1.07, 2.75) times higher prevalence of high HbA1c. In females, higher BMI at 5-years and greater BMI velocity were associated with higher BP at 6–9 years (95% CI: 1.12, 1.40, and 1.42, 2.74, respectively).

Conclusion

Monitoring childhood BMI trajectories may inform cardiometabolic disease screening and prevention efforts in this at-risk population.

导言:人们对太平洋地区儿童糖化血红蛋白(HbA1c)和血压(BP)升高的发生率和风险因素知之甚少。我们研究了萨摩亚 6-9 岁儿童 HbA1c 和 BP 与 2、5 岁体重指数 (BMI) 以及 2-9 岁体重指数速度之间的关系。方法:对正在进行队列研究的 n = 410 名萨摩亚儿童进行了 HbA1c(毛细血管血)和 BP 测量。多层次模型预测了 BMI 的轨迹特征。广义线性回归评估了童年特征和体重指数轨迹与 HbA1c 和血压(作为连续和分类结果)之间的关联。主要照顾者报告的童年特征被用作协变量:总体而言,12.90%(n = 53)的儿童 HbA1c 偏高(≥5.7%),33.17%(n = 136)的儿童血压升高。男性 5 岁时的体重指数和体重指数速度与高 HbA1c 患病率呈正相关。速度每年增加 1 kg/m2 与高 HbA1c 患病率增加 1.71 倍(95% CI:1.07,2.75)有关。在女性中,5 岁时较高的体重指数和较快的体重指数速度与 6-9 岁时较高的血压有关(95% CI:分别为 1.12、1.40 和 1.42、2.74):监测儿童 BMI 轨迹可为这一高危人群的心脏代谢疾病筛查和预防工作提供参考。

Background

The growth and development of infants during the first 1000 days of life are crucial for their health.

Objectives

This study aims to assess the impact of maternal characteristics and infant feeding patterns on infant growth from birth to 18 months.

Methods

Data were derived from the 2-year perspective Mother Infant Study Cohort (MISC) study which included six visits from the third trimester of pregnancy until 18 months postpartum. A convenient sample of 256 pregnant women aged 19–40 years was recruited from Sharjah, Dubai and Ajman in the United Arab Emirates.

Results

Amongst mothers' characteristics, Arab nationality, pre-pregnancy overweight/obesity, higher gestational weight gain and lower physical activity were found to increase the likelihood of infants being overweight at 6, 12 and 18 months. Exclusive breastfeeding was positively correlated with reduced odds of the infant being overweight at 18 months (aOR = 0.31, 95% CI: 0.12–0.81). Breastfeeding for up to 6 months and the introduction of solid foods after 6 months was associated with reduced odds of the infant being overweight at 12 months old (aOR = 4, 95% CI: 1.1–14.6; aOR = 2.97, 95% CI: 1.09–8.08, respectively).

Conclusion

The findings spotlight the influence of maternal characteristics and infant feeding on infant growth. This asserts the need for evidence-based programmes targeting mothers to promote optimal feeding practices and foster healthy child growth.

背景:婴儿出生后 1000 天内的生长发育对其健康至关重要:本研究旨在评估母亲特征和婴儿喂养模式对出生至 18 个月婴儿生长的影响:数据来源于为期两年的母婴队列研究(MISC),其中包括从怀孕三个月到产后 18 个月的六次访视。研究从阿拉伯联合酋长国的沙迦、迪拜和阿治曼招募了 256 名年龄在 19-40 岁之间的孕妇:在母亲的特征中,阿拉伯国籍、孕前超重/肥胖、妊娠体重增加较多和运动量较少都会增加婴儿在 6、12 和 18 个月时超重的可能性。纯母乳喂养与婴儿在 18 个月时超重的几率降低呈正相关(aOR = 0.31,95% CI:0.12-0.81)。母乳喂养长达 6 个月和 6 个月后开始添加固体食物与婴儿 12 个月大时超重几率降低有关(aOR = 4,95% CI:1.1-14.6;aOR = 2.97,95% CI:1.09-8.08):研究结果凸显了母亲特征和婴儿喂养对婴儿生长的影响。结论:研究结果凸显了母亲特征和婴儿喂养对婴儿生长的影响,这表明有必要针对母亲开展循证计划,推广最佳喂养方法,促进儿童健康成长。

Background

Negative familial weight talk may contribute to higher weight bias internalization in pre- and early adolescents (hereafter referred to as children) and may differ by gender, weight status, and race and ethnicity.

Objective

Examine the relationship between negative familial weight talk and weight bias internalization and examine differences by gender, weight status, and race and ethnicity.

Methods

We cross-sectionally analysed 5th–7th graders (10–15 years old) living in Massachusetts (n = 375, 52.3% girls, 21.3% BMI ≥85th percentile, 54.8% non-Hispanic White). Negative familial weight talk frequency during the past 3 months was self-reported and discretized as ‘never,’ ‘occasionally’ (1–9 times) and ‘often’ (>9 times); the Modified Weight Bias Internalization Scale assessed weight bias internalization. Generalized linear models estimated the relationship between negative familial weight talk and weight bias internalization and sub-analyses estimated the relationship across gender, weight status, and race and ethnicity. Results are summarized as ratios of means (RoM).

Results

Children experiencing negative familial weight talk occasionally (RoM = 1.12, p = 0.024) and often (RoM = 1.48, p < 0.001) had significantly higher weight bias internalization than children who never experienced it. In sub-analyses, experiencing negative familial weight talk often was associated with higher weight bias internalization among girls (RoM = 1.66, p < 0.001), boys (RoM = 1.32, p = 0.007), children with BMI <85th percentile (RoM = 1.44, p = 0.007) and BMI ≥85th percentile (RoM = 1.39, p = 0.001), and non-Hispanic White children (RoM = 1.78, p < 0.001), but not Hispanic (RoM = 1.25, p = 0.085) or non-Hispanic Black children (RoM = 1.20; p = 0.31).

Conclusions

Frequent negative familial weight talk was associated with higher weight bias internalization across gender and weight status and in non-Hispanic White children only.

背景:负面的家庭体重谈话可能会导致学龄前和青少年(以下简称儿童)体重偏差内化程度较高,并可能因性别、体重状况、种族和民族而有所不同:研究消极的家庭体重谈话与体重偏差内化之间的关系,并研究不同性别、体重状况、种族和民族之间的差异:我们对居住在马萨诸塞州的 5-7 年级学生(10-15 岁)进行了横截面分析(n = 375,52.3% 为女生,21.3% BMI ≥ 85 百分位数,54.8% 为非西班牙裔白人)。在过去 3 个月中,负面的家庭体重谈话频率是自我报告的,并分为 "从未"、"偶尔"(1-9 次)和 "经常"(大于 9 次);修正体重偏差内化量表评估体重偏差内化情况。广义线性模型估计了负面家庭体重谈话与体重偏差内化之间的关系,子分析估计了不同性别、体重状况、种族和民族之间的关系。结果汇总为平均值之比(RoM):结果:偶尔(RoM = 1.12,p = 0.024)和经常(RoM = 1.48,p = 0.024)经历负面家庭体重谈话的儿童的体重偏差内化率分别为 0.01%和 0.01%:在不同性别和体重状况的儿童中,以及仅在非西班牙裔白人儿童中,经常性的负面家庭体重谈话与较高的体重偏差内化相关。

Introduction

Whilst glucagon-like peptide-1 receptor agonists (GLP1-RAs) are effective for treating adolescent obesity, weight loss maintenance (WLM; preventing weight regain) remains a challenge. Our goal was to investigate appetite/satiety hormones and eating behaviours that may predict WLM with exenatide (a GLP1-RA) versus placebo in adolescents with severe obesity.

Methods

Adolescents who had ≥5% body mass index (BMI) reduction with meal replacement therapy were randomized to 52 weeks of once-weekly exenatide extended release or placebo. In this secondary analysis, eating behaviours and appetite/satiety regulation hormones post-meal replacement therapy (pre-randomization to exenatide or placebo) were evaluated as possible predictors of WLM. Percent change in BMI from randomization to 52 weeks served as the primary measure of WLM.

Results

The analysis included 66 adolescents (mean age 16.0 years; 47% female). Lower leptin response to meal testing was associated with greater WLM in terms of BMI percent change in those receiving exenatide compared to placebo (p = 0.007) after adjusting for sex, age and BMI. There were no other significant predictors of WLM.

Conclusions

Prior to exenatide, lower leptin response to meals was associated with improved WLM with exenatide compared to placebo. The mostly null findings of this study suggest that GLP1-RA treatment may produce similar WLM for adolescents with obesity regardless of age, BMI, sex and eating behaviours.

简介:虽然胰高血糖素样肽-1受体激动剂(GLP1-RA)能有效治疗青少年肥胖症,但维持体重(WLM;防止体重反弹)仍是一项挑战。我们的目标是研究食欲/焦虑激素和进食行为,这些可能会预测重度肥胖青少年使用艾塞那肽(一种GLP1-RA)与安慰剂的减重维持时间:采用代餐疗法后体重指数(BMI)下降≥5%的青少年被随机分配到52周的艾塞那肽缓释剂或安慰剂治疗中,每周一次。在这项二次分析中,评估了代餐疗法后(随机使用艾塞那肽或安慰剂前)的进食行为和食欲/焦虑调节激素,将其作为 WLM 的可能预测因素。从随机到52周的体重指数变化百分比是衡量WLM的主要指标:分析对象包括 66 名青少年(平均年龄 16.0 岁;47% 为女性)。在对性别、年龄和体重指数进行调整后,就体重指数百分比变化而言,接受艾塞那肽治疗的青少年对进餐测试的瘦素反应较低,而接受安慰剂治疗的青少年瘦素反应较高(p = 0.007)。WLM没有其他重要的预测因素:结论:与安慰剂相比,在使用艾塞那肽之前,进餐时较低的瘦素反应与艾塞那肽改善WLM有关。这项研究的大部分结果都是无效的,这表明无论年龄、体重指数、性别和饮食行为如何,GLP1-RA 治疗都能为肥胖症青少年带来相似的 WLM。

Background

Childhood obesity (5–9 years) in India is likely to contribute 11% to the global burden by 2030.

Methods

Data from India's Comprehensive National Nutrition Survey (CNNS, 2016–2018) was used to assess the prevalence and key associated factors of overweight and obesity. Multivariable logistic regression models were applied to identify potential determinants associated with being overweight and obese.

Results

Overweight prevalence (including obesity) varied from 1.6% (0–4 years) to 4.8% (10–19 years). The majority of states reported a higher proportion of adolescents overweight and obese, than younger age group 5–9 years. A significantly higher prevalence of children and adolescents with obesity was reported in higher wealth quintiles and residents of urban areas. The prevalence of overweight and obesity and associated demographic and health factors in India included: the presence of NCD risk factor (adolescents: 1.68, 95% CI [1.31–2.14]), micronutrient deficiency (5–9 years children: 1.72, 95% CI [1.30–2.28]), mother's education (5–9 years children: 4.84, 95% CI [2.92–8.03]; adolescents: 2.17, 95% CI [1.42–3.32]), wealth (adolescents: 1.92, 95% CI [1.16–3.19]), place of residence (5–9 years children: 1.68, 95% CI [1.39–2.03]; adolescents: 1.39, 95% CI [1.16–1.66]), child age (5–9 years children: 1.64, 95% CI [1.40–1.93], and screen-time (adolescents: 1.63, 95% CI [1.22–2.19].

Conclusion

The findings set out policy and research recommendations to pave the path for curtailing the increasing prevalence of overweight and obesity and achieving the World Health Assembly's Global Nutrition target of ‘no increase in childhood overweight (Target 4) by 2025’.

背景:到 2030 年,印度儿童肥胖症(5-9 岁)可能占全球负担的 11%:方法:利用印度全国营养综合调查(CNNS,2016-2018 年)的数据来评估超重和肥胖的发生率及主要相关因素。采用多变量逻辑回归模型来确定与超重和肥胖相关的潜在决定因素:超重率(包括肥胖)从 1.6%(0-4 岁)到 4.8%(10-19 岁)不等。大多数州报告的青少年超重和肥胖比例高于 5-9 岁年龄组。据报告,在财富五分位数较高的地区和城市居民中,儿童和青少年的肥胖率明显较高。印度超重和肥胖的发生率以及相关的人口和健康因素包括:存在非传染性疾病风险因素(青少年:1.68,95% CI [1.31-2.14])、微量营养素缺乏(5-9 岁儿童:1.72,95% CI [1.30-2.28])、母亲受教育程度(5-9 岁儿童:4.84,95% CI [1.30-2.28]):4.84,95% CI [2.92-8.03];青少年:2.17,95% CI [1.42-3.32])、财富(青少年:1.92,95% CI [1.16-3.19])、居住地(5-9 岁儿童:1.68,95% CI [1.39-2.03];青少年:1.39,95% CI [1.39-2.03]):1.39,95% CI [1.16-1.66])、儿童年龄(5-9 岁儿童:1.64,95% CI [1.40-1.93])和屏幕时间(青少年:1.63,95% CI [1.16-3.19]):1.63, 95% CI [1.22-2.19]:研究结果提出了政策和研究建议,为遏制超重和肥胖症的日益普遍以及实现世界卫生大会提出的 "到 2025 年儿童超重不再增加(目标 4)"的全球营养目标铺平了道路。

Background

Paediatric obesity disproportionately impacts individuals from minoritized racial and ethnic backgrounds. Recent guidelines support use of anti-obesity pharmacotherapy for adolescents with obesity, but the potential impact on disparities in obesity prevalence has not been evaluated.

Objectives

To model changes in obesity prevalence with increasing utilization of anti-obesity pharmacotherapy among adolescents.

Methods

Data representative of American adolescents ages 12–17 years were obtained from the National Health and Nutrition Examination Survey, cycles 2011 through pre-pandemic 2020. A body mass index (BMI) reduction of 16.7% was applied to each participant based on clinical trial results of weekly subcutaneous semaglutide 2.4 mg among adolescents. Utilization disparities were based on utilization of the same medication class among adults. Obesity prevalence was calculated assuming utilization of 10%–100%, stratified by race and ethnicity.

Results

Among 4442 adolescents representing 26 247 384 American adolescents, projected overall obesity prevalence decreased from 22.2% to 8.4% with 100% utilization. However, disparities increased relative to Non-Hispanic White youth, with prevalence among Non-Hispanic Black and Mexican American youth ranging from 40%–60% higher to 90%–120% higher, respectively.

Conclusions

Increasing utilization of anti-obesity pharmacotherapy may widen relative disparities in obesity, particularly if utilization is unequal. Advocacy for equitable access is needed to minimize worsening of obesity-related disparities.

背景:儿科肥胖症对少数种族和民族背景的人造成了极大的影响。最近的指南支持对患有肥胖症的青少年使用抗肥胖药物治疗,但尚未评估其对肥胖患病率差异的潜在影响:目的:模拟随着青少年使用抗肥胖药物疗法的增加,肥胖患病率的变化情况:方法:从美国国家健康与营养调查(National Health and Nutrition Examination Survey)中获得了 2011 年至 2020 年大流行前的 12-17 岁美国青少年的代表性数据。根据青少年每周皮下注射 2.4 毫克塞马鲁肽的临床试验结果,将每位参与者的体重指数(BMI)降低 16.7%。用药差异是根据成人使用同类药物的情况计算得出的。假设使用率为 10%-100%,按种族和民族分层计算肥胖患病率:在代表 26 247 384 名美国青少年的 4442 名青少年中,预计总体肥胖率从 22.2% 降至 8.4%,使用率为 100%。然而,与非西班牙裔白人青少年相比,差距有所扩大,非西班牙裔黑人和墨西哥裔美国青少年的患病率分别高出 40%-60% 到 90%-120% 不等:增加抗肥胖药物疗法的使用可能会扩大肥胖的相对差异,尤其是在使用不平等的情况下。需要倡导公平使用,以尽量减少肥胖相关差异的恶化。

Background

Mid-upper arm circumference (MUAC) was recommended for screening of adolescents with obesity, although its diagnostic performance with respect to high-precision assessment of body composition remains unknown.

Objective

To evaluate the diagnostic performance of MUAC in identifying obesity and metabolic syndrome in U.S. adolescents.

Methods

A cross-sectional study was conducted using National Health and Nutrition Examination Survey (NHANES) data (2011–2018) of adolescents aged 12–19. We calculated the area under the receiver operating characteristic curve, sensitivity, specificity, positive and negative predictive values and likelihood ratios of MUAC in identifying obesity and metabolic syndrome.

Results

In our study, data of 5496 adolescents, including 2665 females, were analysed. The prevalence of obesity was higher in boys (14%) than girls (10%), whilst metabolic syndrome was more common in males (2.6%) than females (1.7%). The area under the curve (AUC) of MUAC in identifying obesity was 0.69 in boys and 0.86 in girls, whilst the AUC of MUAC in identifying metabolic syndrome was 0.91 in boys and 0.87 in girls. The optimal MUAC cut-off for identifying adolescents with obesity was 28.3 cm in boys (sensitivity: 64.8%, specificity: 85.5%) and 30.8 cm in girls (sensitivity: 67.9%, specificity: 90.1%).

Conclusions

MUAC was a good indicator of both obesity and metabolic syndrome, with higher accuracy in girls.

Background

The association of ultra-processed food (UPF) consumption with obesity and adipose tissue in children/adolescents remains poorly understood.

Objective

To assess the association of UPF consumption with excessive weight (EW—defined as BMI-for-age ≥+1 z-score) and body composition at 15 years.

Methods

In a birth cohort, daily UPF consumption was estimated by Food Frequency Questionnaires at 6 and 15 years. Those in the higher tercile of UPF consumption at both follow-ups were the ‘always-high consumers’. Air-displacement plethysmography provided fat mass (FM-kg), fat-free mass (FFM-kg), %FM, %FFM, FM index (FMI-kg/m2) and FFM index (FFMI-kg/m2). Logistic regression and linear regression were used to estimate, respectively, odds ratios and beta coefficients.

Results

Amongst 1584 participants, almost one in every seven were always-high consumers. In crude analyses, there was no association between variation in UPF consumption and EW, and body fat parameters were lower in the always-high consumer group than amongst the always-low consumers, in both sexes. With adjustment for confounders, the odds ratio for EW was higher in the always-high consumer than amongst the always-low consumer group, and the direction of the associations with FM parameters was reversed: males from the always-high consumer group presented almost twice as high FM (10.5 vs. 18.6 kg; p < 0.001) and twice as high FMI (3.4 vs. 6.3 kg/m2; p < 0.001) than the always-low consumer group, and females from the always-high consumer group presented on average 32% more FM and FMI than the always-low consumer group.

Conclusions

In crude and adjusted analyses there was a strong association between high UPF consumption from childhood to adolescence, EW and higher body fat parameters at 15 years, but its deleterious association with body adiposity was only uncovered after adjusting for confounders.

人们对儿童/青少年食用超加工食品(UPF)与肥胖和脂肪组织之间的关系仍然知之甚少。

Objective

Rising prevalence of obesity has led to increased rates of prediabetes and diabetes mellitus (DM) in children. This study compares rates of prediabetes and diabetes using two recommended screening tests (fasting plasma glucose [FPG] and haemoglobin A1c [HbA1c]).

Study Design

Data were collected prospectively from 37 multi-component paediatric weight management programs in POWER (Paediatric Obesity Weight Evaluation Registry).

Results

For this study, 3962 children with obesity without a known diagnosis of DM at presentation and for whom concurrent measurement of FPG and HbA1c were available were evaluated (median age 12.0 years [interquartile range, IQR 9.8, 14.6]; 48% males; median body mass index 95th percentile [%BMIp95] 134% [IQR 120, 151]). Notably, 10.7% had prediabetes based on FPG criteria (100–125 mg/dL), 18.6% had prediabetes based on HbA1c criteria (5.7%–6.4%), 0.9% had DM by FPG abnormality (≥126 mg/dL) and 1.1% had DM by HbA1c abnormality (≥6.5%). Discordance between the tests was observed for youth in both age groups (10–18 years [n = 2915] and age 2–9 years [n = 1047]).

Conclusion

There is discordance between FPG and HbA1c for the diagnosis of prediabetes and DM in youth with obesity. Further studies are needed to understand the predictive capability of these tests for development of DM (in those diagnosed with prediabetes) and cardiometabolic risk.

肥胖症发病率的上升导致了儿童糖尿病前期和糖尿病(DM)发病率的上升。本研究使用两种推荐的筛查测试(空腹血浆葡萄糖 [FPG] 和血红蛋白 A1c [HbA1c])对糖尿病前期和糖尿病的发病率进行了比较。

Background

Obesity is a heterogeneous disease with variable treatment response. Identification of the unique constellation of contributors to obesity may allow for targeted interventions and improved outcomes.

Objective

Identify empirically derived phenotypes of pediatric patients with obesity based on appetitive and psychological correlates of obesity.

Methods

This cross-sectional study included patients aged 5–12 years who were treated in a weight management clinic and completed standard intake questionnaires including Child Eating Behavior Questionnaire (CEBQ), Vanderbilt ADHD Scale and Pediatric Symptom Checklist. Phenotypes were elicited using latent profile analysis of 12 indicators: eight CEBQ subscales, inattention, hyperactivity/impulsivity, internalizing and externalizing symptoms.

Results

Parents/guardians of 384 patients (mean age 9.8 years, mean BMI 30.3 kg/m2) completed the intake questionnaires. A 4-phenotype model best fits the data. Hedonic Impulsive phenotype (42.5%) exhibited high food enjoyment and hyperactivity/impulsivity. Inattentive Impulsive phenotype (27.4%) exhibited overall low food approach and high food avoid behaviours, and highest inattention. Hedonic Emotional phenotype (20.8%) scored the highest on food enjoyment, internalizing and externalizing symptoms. Picky Eating phenotype (9.3%) scored the lowest on food approach, inattention, hyperactivity/impulsivity, internalizing and externalizing symptoms.

Conclusion

Appetitive traits and psychological symptoms appear to cluster in distinct patterns, giving rise to four unique phenotypic profiles, which, if replicated, may help inform the development of tailored treatment plans.

背景:肥胖症是一种异质性疾病,对治疗的反应各不相同。确定导致肥胖的独特因素可能有助于采取有针对性的干预措施并改善治疗效果:根据肥胖的食欲和心理相关因素,确定儿科肥胖症患者的经验表型:这项横断面研究纳入了在体重管理诊所接受治疗的 5-12 岁患者,他们填写了标准的入院问卷,包括儿童进食行为问卷 (CEBQ)、范德比尔特多动症量表和儿科症状检查表。通过对12个指标(CEBQ的8个分量表、注意力不集中、多动/冲动、内化症状和外化症状)进行潜在特征分析,得出表型:384名患者(平均年龄9.8岁,平均体重指数30.3 kg/m2)的家长/监护人填写了入组问卷。4种表型模型最符合数据。享乐型冲动表型(42.5%)表现出高度的食物享受和多动/冲动。注意力不集中冲动型表型(27.4%)总体表现为低食物接近行为和高食物回避行为,注意力最不集中。享乐情绪表型(20.8%)在享受食物、内化和外化症状方面得分最高。挑食表型(9.3%)在进食、注意力不集中、多动/冲动、内化和外化症状方面得分最低:结论:食欲特征和心理症状似乎以不同的模式聚集在一起,形成了四种独特的表型特征。
