Background

The mediobasal hypothalamus (MBH) is a key brain area for regulation of energy balance. Previous neuroimaging studies suggest that T2-based signal properties indicative of cellular inflammatory response (gliosis) are present in adults and children with obesity, and predicts greater adiposity gain in children at risk of obesity.

Objectives/Methods

The current study aimed to extend this concept to the early life period by considering if, in full-term healthy neonates (up to n = 35), MRI evidence of MBH gliosis is associated with changes in early life (neonatal to six months) body fat percentage measured by DXA.

Results

In this initial study, neonatal T2 signal in the MBH was positively associated with six-month changes in body fat percentage.

Conclusion

This finding supports the notion that underlying processes in the MBH may play a role in early life growth and, by extension, childhood obesity risk.

背景:基底中层下丘脑(MBH)是调节能量平衡的关键脑区。以往的神经影像学研究表明,成人和肥胖儿童中存在指示细胞炎症反应(胶质细胞增多症)的基于 T2 的信号特性,并可预测肥胖风险儿童的肥胖程度:本研究旨在将这一概念延伸到生命早期,研究在足月健康新生儿(最多 35 人)中,MBH 神经胶质增生的 MRI 证据是否与生命早期(新生儿到六个月)通过 DXA 测量的体脂百分比变化相关:在这项初步研究中,新生儿 MBH 的 T2 信号与六个月后体脂百分比的变化呈正相关:结论:这一发现支持了一种观点,即 MBH 的潜在过程可能在生命早期的生长过程中发挥作用,进而影响儿童肥胖风险。

Introduction

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease among US children. Studies have associated food insecurity with MASLD in adults, but there are few studies of pediatric MASLD, particularly in high-risk populations. We assessed the impact of household food insecurity at 4 years of age on MASLD in Latinx children.

Methods

Using a prospective cohort design, Latina mothers were recruited during pregnancy and followed with their children until early to mid-childhood. Our primary exposure was household food insecurity at 4 years of age measured using the validated US Household Food Security Food Module. Our primary outcome, MASLD, was defined as alanine transaminase (ALT) ≥95th% for age/gender plus body mass index (BMI) ≥85% at time of ALT measurement (assessed between ages 5–12). We used multivariable logistic regression models to test for independent associations between household food insecurity and pediatric MASLD.

Results

Among 136 children, 28.7% reported household food insecurity at 4 years of age and 27.2% had MASLD in early to middle childhood. Approximately 49% of children with MASLD and 21% of children without MASLD were food insecure (p < 0.01). Exposure to household food insecurity at age 4 was independently associated with a 3.7-fold higher odds of MASLD later in childhood (95% CI: 1.5–9.0, p < 0.01).

Conclusions

Exposure to household food insecurity at 4 years of age was associated with increased risk for MASLD later in childhood. Further studies are needed to explore mechanism(s) and impact of reducing food insecurity on risk for MASLD.

简介代谢功能障碍相关性脂肪肝(MASLD)是美国儿童中最常见的慢性肝病。有研究表明,食物不安全与成人代谢性脂肪肝有关,但针对儿童代谢性脂肪肝的研究却很少,尤其是针对高危人群的研究。我们评估了拉美裔儿童 4 岁时家庭食物不安全对 MASLD 的影响:方法:我们采用前瞻性队列设计,在拉美裔母亲怀孕期间对她们进行招募,并对她们的孩子进行跟踪调查,直到他们长大成人。我们的主要暴露指标是 4 岁时的家庭粮食不安全状况,使用经过验证的美国家庭粮食安全粮食模块进行测量。我们的主要结果--MASLD--被定义为丙氨酸转氨酶(ALT)≥年龄/性别的95%,加上测量ALT时体重指数(BMI)≥85%(评估时间为5-12岁)。我们使用多变量逻辑回归模型来检验家庭粮食不安全与小儿 MASLD 之间的独立关联:结果:在 136 名儿童中,28.7% 的儿童在 4 岁时报告了家庭粮食不安全状况,27.2% 的儿童在儿童早期至中期患有 MASLD。约 49% 患有 MASLD 的儿童和 21% 未患 MASLD 的儿童缺乏粮食安全(P4岁时暴露于家庭食物无保障的情况与儿童后期罹患MASLD的风险增加有关。需要开展进一步的研究,以探索减少食物不安全对罹患 MASLD 风险的影响机制。

Importance

The effectiveness of anti-obesity medications for children and adolescents is unclear.

Objective

To update the evidence on the benefits and harms of anti-obesity medication.

Data Sources

Cochrane CENTRAL, MEDLINE, ClinicalTrials.gov and WHO ICTRP (1/1/16–17/3/23).

Study Selection

Randomized controlled trials ≥6 months in people <19 years living with obesity.

Data Extraction and Synthesis

Screening, data extraction and quality assessment conducted in duplicate, independently.

Main Outcomes and Measures

Body mass index (BMI): 95th percentile BMI, adverse events and quality of life.

Results

Thirty-five trials (N = 4331), follow-up: 6–24 months; age: 8.8–16.3 years; BMI: 26.2–41.7 kg/m2. Moderate certainty evidence demonstrated a −1.71 (95% confidence interval [CI]: −2.27 to −1.14)-unit BMI reduction, ranging from −0.8 to −5.9 units between individual drugs with semaglutide producing the largest reduction of −5.88 kg/m2 (95% CI: −6.99 to −4.77, N = 201). Drug type explained ~44% of heterogeneity. Low certainty evidence demonstrated reduction in 95th percentile BMI: −11.88 percentage points (95% CI: −18.43 to −5.30, N = 668). Serious adverse events and study discontinuation due to adverse events did not differ between medications and comparators, but medication dose adjustments were higher compared to comparator (10.6% vs 1.7%; RR = 3.74 [95% CI: 1.51 to 9.26], I2 = 15%), regardless of approval status. There was a trend towards improved quality of life. Evidence gaps exist for children, psychosocial outcomes, comorbidities and weight loss maintenance.

Conclusions and Relevance

Anti-obesity medications in addition to behaviour change improve BMI but may require dose adjustment, with 1 in 100 adolescents experiencing a serious adverse event.

重要性:抗肥胖药物对儿童和青少年的疗效尚不明确:数据来源:Cochrane CENTRAL、MEDLINE、ClinicalTrials.gov 和 WHO ICTR:数据来源:Cochrane CENTRAL、MEDLINE、ClinicalTrials.gov 和 WHO ICTRP(1/1/16-17/3/23):数据提取和综合:筛选、数据提取和质量评估一式两份,独立进行:身体质量指数(BMI):第95百分位数BMI、不良事件和生活质量:35项试验(N = 4331),随访时间:6-24个月;年龄:8.8-16.3岁;体重指数:26.2-41.7 kg/m2。中度确定性证据显示,BMI 降低了-1.71(95% 置信区间 [CI]:-2.27 至-1.14)个单位,不同药物之间的降低幅度从-0.8 至-5.9 个单位不等,其中以塞马鲁肽的降低幅度最大,为-5.88 kg/m2(95% 置信区间:-6.99 至-4.77,N = 201)。药物类型解释了~44%的异质性。低确定性证据显示,BMI 第 95 百分位数减少了:-11.88 个百分点(95% CI:-18.43 至 -5.30,N = 668)。药物与对比药之间的严重不良事件和因不良事件而中止研究的情况没有差异,但药物剂量调整率高于对比药(10.6% vs 1.7%;RR = 3.74 [95% CI:1.51 to 9.26],I2 = 15%),与批准情况无关。有改善生活质量的趋势。在儿童、社会心理结果、合并症和体重减轻维持方面存在证据缺口:除了改变行为外,抗肥胖药物还能改善体重指数,但可能需要调整剂量,每100名青少年中就有1人发生严重不良事件。

Background

Limited research on alanine aminotransferase (ALT) screening for metabolic dysfunction-associated steatotic liver disease (MASLD) among US Asian/Pacific Islander (PI) children necessitates investigation in this heterogeneous population.

Objective

Examine ALT elevation among Asian/PI children with overweight or obesity.

Methods

Elevated ALT prevalence (clinical threshold) and association with body mass index ≥85th percentile were compared among 18 402 Asian/PI and 25 376 non-Hispanic White (NHW) children aged 9–17 years using logistic regression.

Results

ALT elevation was more prevalent among Asian/PI (vs. NHW) males with overweight (4.0% vs. 2.7%), moderate (7.8% vs. 5.3%) and severe obesity (16.6% vs. 11.5%), and females with moderate (5.1% vs. 3.0%) and severe obesity (10.2% vs. 5.2%). Adjusted odds of elevated ALT were 1.6-fold and ~2-fold higher for Asian/PI (vs. NHW) males and females (with obesity), respectively. Filipino, Chinese and Southeast Asian males had 1.7–2.1-fold higher odds, but Native Hawaiian/PI (NHPI) and South Asian males did not significantly differ (vs. NHW). Filipina and Chinese females with obesity had >2-fold higher odds, Southeast and South Asian females did not differ and NHPI findings were mixed (vs. NHW).

Conclusion

High elevated ALT prevalence among Asian/PI children with overweight and obesity emphasizes the need for MASLD risk assessment and examination of ethnic subgroups.

背景:美国亚太裔(PI)儿童丙氨酸氨基转移酶(ALT)筛查代谢功能障碍相关性脂肪性肝病(MASLD)的研究有限,因此有必要对这一异质性人群进行调查:研究超重或肥胖的亚裔/太平洋岛民儿童的 ALT 升高情况:采用逻辑回归法比较了 18 402 名 9-17 岁亚裔/PI 儿童和 25 376 名非西班牙裔白人(NHW)儿童的 ALT 升高率(临床阈值)以及与体重指数≥85 百分位数的关系:ALT升高在超重(4.0% vs. 2.7%)、中度肥胖(7.8% vs. 5.3%)和重度肥胖(16.6% vs. 11.5%)的亚裔/PI(vs. NHW)男性以及中度肥胖(5.1% vs. 3.0%)和重度肥胖(10.2% vs. 5.2%)的女性中更为普遍。亚裔/菲律宾裔(与非正常体重者相比)男性和女性(肥胖)ALT 升高的调整几率分别高出 1.6 倍和 2 倍。菲律宾裔、华裔和东南亚裔男性的几率高出 1.7-2.1 倍,但夏威夷原住民/菲律宾裔(NHPI)和南亚裔男性(与 NHW 相比)并无显著差异。菲律宾裔和华裔女性肥胖者的几率高出 2 倍以上,东南亚和南亚女性没有差异,而夏威夷原住民/菲律宾裔(NHPI)和南亚男性的结果不一(与 NHW 相比):结论:在超重和肥胖的亚裔/菲律宾裔儿童中,谷丙转氨酶升高的发生率很高,这强调了对种族亚群进行 MASLD 风险评估和检查的必要性。

Background

Food and nutrition security interventions have been demonstrated to optimize health, prevent and treat chronic diseases among adult populations. Despite the increasing prevalence and intersection of food insecurity and childhood obesity in the United States, there are few food and nutrition security interventions targeted to children and families.

Objectives

The primary purpose of this phase I randomized, crossover trial was to assess the safety, acceptability and satisfaction of a meal kit delivery program among children with obesity living in households with food insecurity. Secondarily, we assessed the feasibility of our study design, recruitment and retention to inform future larger scale trials.

Methods

We delivered 6 weeks of healthy meal kits, which included fresh pre-portioned ingredients and simple picture-based recipes (two recipes/week) in English or Spanish to prepare one-pot, under 30-min meals (after preparation ~ 10 servings/week).

Results

Caregivers received and prepared the meal kits and reported overall satisfaction with the meal kit delivery program.

Conclusion

A meal kit delivery intervention for children with obesity and food insecurity is acceptable and a phase I randomized, crossover trial is feasible.

背景:食物和营养安全干预措施已被证明可优化健康、预防和治疗成年人群中的慢性疾病。尽管在美国粮食不安全和儿童肥胖症的发生率和交叉率越来越高,但针对儿童和家庭的粮食和营养安全干预措施却很少:这项 I 期随机交叉试验的主要目的是评估食物无保障家庭中肥胖儿童对送餐计划的安全性、可接受性和满意度。其次,我们还评估了研究设计、招募和保留的可行性,为今后更大规模的试验提供参考:我们提供了为期 6 周的健康餐包,其中包括预先配好的新鲜食材和简单的图片食谱(每周两份食谱),用英语或西班牙语烹制一锅 30 分钟以内的饭菜(准备后~每周 10 份):结果:护理人员收到并准备了餐包,并对餐包递送计划总体表示满意:结论:针对肥胖和食物无保障儿童的送餐干预措施是可以接受的,第一阶段随机交叉试验也是可行的。

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。
