Children’s diets in school-age are inherently unhealthy, with few meeting dietary recommendations. Yet, little is known about similarities and differences on dietary patterns across countries and their association with obesity. We aimed to derive dietary patterns in childhood and explore their association with adiposity-related outcomes in childhood and adolescence. This study included data from six European countries (Spain, France, UK, Greece, Lithuania and Norway) during childhood (n = 1597) and adolescence (n = 803). Using a food frequency questionnaire, we derived data-driven dietary patterns through exploratory factor analyses and calculated the Mediterranean KIDMED index. We assessed body mass index z-score (zBMI), fat mass proportion and waist-to-height ratio at both visits. Associations were estimated using generalized linear regressions, adjusted for key-confounders. “Meat”, “Dairy”, “Western”, “Healthy” and “Sweets and fats” dietary patterns were derived. Norwegian children showed better diet quality, with higher consumption of fruits and vegetables, and highest “Healthy pattern” adherence, and Lithuanian children, the worst, with higher sweets consumption, and highest “Western pattern” adherence. Children with lower intake of healthy foods (vegetables, fruits, fish) tended to have higher adiposity, e.g., children with average or low “Healthy pattern” adherence (vs. high) had higher fat mass proportion in childhood (average: β (95% CI) 1.44 (0.48; 2.39), low: 1.10 (0.09; 2.12)). Low adherence to a “Healthy pattern” (vs. high) was associated with increased adolescent zBMI, and child and adolescent waist-to-height ratio. Low “Dairy pattern” adherence (vs. high), was associated with lower zBMI and fat mass in childhood, but not in adolescence. No significant associations were seen with the KIDMED index. Many European children have poor diets and a low adherence to a healthy diet pattern may be of concern for adiposity-related outcomes. Assessment of children’s dietary patterns can help tailor dietary advice and provide support for families aiming to prevent future excess weight gain.

This study aimed to systematically review the existing literature to summarize the incidence and risk factors of post-metabolic and bariatric surgery hypoglycemia (MBSH). We searched PubMed, Medline, Embase, and the Cochrane Library databases for the studies published from inception to August 2023. Randomized controlled trials and analytical studies that investigated the incidence or risk factors of MBSH after different surgery techniques (including Roux-en-Y gastric bypass, sleeve gastrectomy, gastric banding, duodenal switch, omega-loop gastric bypass, and vertical banded gastroplasty) were involved. The incidence and risk factors of MBSH were extracted and described separately based on different diagnostic criteria and then summarized the risk factors and their statistical findings collectively. Twenty-nine studies were reviewed with follow-up ranging from 1 to 22 years. The incidence of MBSH ranged significantly across different diagnostic methods: 2.6–66.4% (self-report), 6.6–61.8% (oral glucose tolerance test), 29.4–78.6% (mixed-meal tolerance test), and 50–75% (continuous glucose monitoring). Patients with a mean age of 49.8 years and 89.0% of them were women with a better glycemic control who undergo RYGB and achieve 86.5% of estimated weight loss from surgery should be particularly vigilant about the possibility of developing MBSH. Distinct biomarkers such as IGF-1 (OR 1.06), fasting glicentin (AUC 0.81), HbA1c (AUC 0.76), and absolute weight reduction (AUC 0.72), greater fluctuations in glucose (OR 1.98) are valuable in promptly detecting MBSH. Specifically, patients with prior cholecystectomy or antidepressant therapy should be particularly cautious. The review highlights higher MBSH risk in younger women with significant weight loss after RYGB, and those with prior cholecystectomy or antidepressant use. Systematic summarization of MBSH criteria allowed us to identify the predictors for MBSH, which can aid in early diagnosis and treatment, reducing the need for prolonged monitoring.

Body weight gain is a prevalent adverse effect observed in psychiatric medication therapy. With the notable increase in mental health diagnoses among children and adolescents over the last decade, exacerbated by the COVID-19 pandemic, the use of medications associated with weight gain poses an additional risk for obesity development. This study aimed to identify psychiatric drugs that may induce weight gain in children as a side effect. Twenty-nine publications were included in this systematic review, investigating the effects of nineteen different drugs on children's weight. The majority of these drugs belonged to atypical antipsychotics and anticonvulsants. Nearly all included articles reported that the examined substances resulted in weight gain in children. As childhood obesity has become a significant problem with various metabolic, psychological and social consequences, it is crucial to carefully consider therapy options. In addition to evaluating effectiveness, it is important to also assess the potential for weight gain. Clinicians and nutrition specialists should individually evaluate patients' nutritional needs, evaluate obesity risk, and provide appropriate dietary guidance to minimalize the risk of weight gain.

Given the high prevalence of overweight and obesity and high comorbidity of depressive symptoms, there is a need for low-threshold, accessible care approaches for people with overweight/obesity aimed at improving mental health. Internet and mobile-based interventions (IMI) represent an innovative complementary treatment option. This review systematically searches for IMI aimed at improving mental health in people with overweight/obesity. We conducted a systematic literature search according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria in the databases MEDLINE, Cochrane Library, PsycINFO, Web of Science and Google Scholar. Randomized controlled trials (RCTs) of IMI for adults with overweight/obesity and comorbid depressive symptoms aiming at improving mental health were screened and extracted. Study quality was assessed with RoB 2 (revised Cochrane Risk of Bias tool in RCTs). After excluding duplicates, n = 790 results were included in title and abstract screening. After full-text-screening of n = 26 studies, n = 3 RCT studies were included. All interventions aimed to reduce both weight and depressive symptoms. In two RCTs, a significant reduction in both depressive symptoms and weight was achieved. One RCT indicated a significant reduction in depressive symptoms, but not in weight. Two intervention had a duration of 6 months and were guided by health carers, the third takes 3 months and can be used without professional guidance. There is evidence that IMI are effective in improving mental health for people with overweight/obesity and comorbid depressive symptoms. However, currently there are few interventions aiming at reducing depressive symptoms, all targeting English-speaking people. As IMI for depressive symptoms can be easily integrated in the somatic therapy of obesity as additional option and has high public health potential, target group-adapted and low-threshold accessible interventions in different languages should be developed and implemented for improving mental health in people with overweight/obesity.

鉴于超重和肥胖症的高发病率以及抑郁症状的高合并率，有必要为超重/肥胖症患者提供低门槛、无障碍的护理方法，以改善他们的心理健康。基于互联网和移动设备的干预（IMI）是一种创新的辅助治疗方法。本综述系统地检索了旨在改善超重/肥胖症患者心理健康的 IMI。我们根据 PRISMA（系统综述和元分析的首选报告项目）标准，在 MEDLINE、Cochrane Library、PsycINFO、Web of Science 和 Google Scholar 等数据库中进行了系统的文献检索。筛选并提取了针对超重/肥胖并伴有抑郁症状的成年人、旨在改善心理健康的 IMI 随机对照试验（RCT）。研究质量采用 RoB 2（修订版 Cochrane Risk of Bias RCTs 工具）进行评估。在排除重复研究后，共有 790 项研究结果被纳入标题和摘要筛选。在对 n = 26 项研究进行全文筛选后，纳入了 n = 3 项 RCT 研究。所有干预措施都旨在减轻体重和抑郁症状。在两项研究中，抑郁症状和体重均有显著减轻。一项研究表明，抑郁症状明显减轻，但体重没有减轻。两项干预持续时间为 6 个月，由医护人员指导；第三项干预持续时间为 3 个月，无需专业指导。有证据表明，对于超重/肥胖并伴有抑郁症状的人来说，综合心理干预能有效改善他们的心理健康。然而，目前旨在减轻抑郁症状的干预措施并不多，而且都是针对讲英语的人。由于治疗抑郁症状的 IMI 可作为附加选项轻松融入肥胖症的躯体治疗中，并且具有很高的公共卫生潜力，因此应开发和实施适合目标群体、低门槛、使用不同语言的干预措施，以改善超重/肥胖症患者的心理健康。Prospero 注册号：CRD42023361771。

Adiposity is positively associated with risk of some cancer sites and other health conditions in men; however, it is unclear if endogenous hormones play a role in these associations. We examined how body composition, measured from magnetic resonance imaging (MRI) and common measures of adiposity (e.g., body mass index (BMI)), are related to hormone concentrations in men from the UK Biobank study. Up to 16,237 men with available body composition data (including visceral, subcutaneous, and liver fat, muscle fat infiltration (MFI), lean tissue, and common adiposity measures) and serum hormone measurements (insulin-like growth factor-I (IGF-I), total testosterone, sex hormone-binding globulin (SHBG), and calculated free testosterone) were included. Multivariable-adjusted linear regression models were used to determine the geometric mean hormone and SHBG concentrations across categories of each exposure. Common measurements of adiposity were highly correlated with MRI measures of central and total adiposity (r = 0.76–0.91), although correlations with ectopic fat (liver fat and MFI) were lower (r = 0.43–0.54). Most adiposity measurements showed an inverse U- or J-shaped association with circulating IGF-I and free testosterone; however, MFI was linearly inversely associated, and lean tissue volume was positively associated with both IGF-I and free testosterone concentrations. All body composition measures were inversely associated with total testosterone and SHBG concentrations (relative geometric mean difference between Q5 vs. Q1: 20–30%). Our results show that common adiposity and most MRI measures of adiposity relate similarly to serum hormone concentrations; however, associations with ectopic fat (particularly MFI) and lean tissue were different.

Childhood obesity is a global health concern that has its origins before birth. Although genetics plays a crucial role, increasing evidence suggests that epigenetic modifications during fetal life could also influence its incidence. In this model, during the fetal period, interactions between genetic makeup, intrauterine factors, and environmental conditions, increase the risk of childhood obesity. This is in accordance with the Developmental Origins of Health and Disease (DOHaD) hypothesis, in which specific intrauterine environments can have long-lasting effects on the immune system’s essential functions during crucial stages of fetal growth, resulting in permanent changes to the immune function of the offspring. Consequently, dysfunction can consequently make the offspring more prone to inflammatory and immune-related disorders later in life. In this review, we examine how maternal inflammation could influence the risk of childhood obesity. We propose that during pregnancy, modification of the expression of critical genes in metabolic and signaling pathways, such as the kynurenine (Kyn) pathway, occurs due to increased levels of maternal inflammation. We also propose that such expression differences are mediated by epigenetic changes. Furthermore, we also hypothesize that the Kyn pathway produces metabolites that have immunoregulatory effects and may play a crucial role in regulating inflammation during pregnancy. As a result, interventions aimed at improving maternal inflammation may be able to help alleviate the risk of childhood obesity.

To explore effective exercise types for reducing chronic inflammation in individuals with overweight and obesity (IOO) while accounting for confounders. A systematic search for RCTs in English between January 2000 and August 2023 was conducted to evaluating exercise effects on inflammatory biomarkers in IOO. A network meta-analysis conducted. A total of 123 RCTs were analyzed. Different exercise type yielded distinct effects on various inflammatory biomarkers. Specifically, aerobic exercise combined with resistance training (COM) and aerobic exercise (AE) were the most effective for improving leptin levels. AE exhibited the greatest effectiveness in reducing CRP and increasing adiponectin. High-intensity interval training (HIIT) was identified as the most effective exercise modality for ameliorating IL-6, TNF-α, and IL-10. Resistance training (RT) had the least effect compared to other exercise types. Meta regression and subgroup analyses revealed that high-intensity AE demonstrated a greater effect size compared to moderate-intensity AE. The impact of AE on IL-10 was positively associated with both the training period and the age of participants. Positive correlations were observed between reductions in body fat and the effect sizes of CRP, TNF-α, and IL-10. Gender influenced AE effects on IL-6 and TNF-α, with females responding better. This study highlights the potential of exercise in alleviating the inflammatory status in IOO, with different exercise types showing various effects on specific inflammatory biomarkers. The intensity and duration of exercise had a dose-response relationship with intervention effectiveness. Changes in body composition correlated with the effectiveness of the intervention. COM, AE, and HIIT are recommended exercise approaches.

The roles of overall diet quality in linking genetic background with anthropometric measures are unclear, particularly regarding the recently developed Planetary Health Diet (PHD). This study aims to determine if the PHD mediates or moderates the relationship between genetic susceptibility to obesity and anthropometric measures. The study involved 2942 individuals from a Finnish population-based cohort (54% women, mean age 53 (SD ± 13) years). Habitual diet was assessed using a validated 130-item food frequency questionnaire, and the PHD Score (total score range 0–13 points) was adapted for Finnish food culture to evaluate diet quality. Genetic susceptibility to obesity was evaluated with a polygenic risk score (PRS) based on one million single nucleotide polymorphisms associated with body mass index (BMI). Baseline anthropometrics included weight, height, waist circumference (WC), and body fat percentage, with changes in these measures tracked over 7 years. A five-step multiple linear regression model and multivariable logistic regression with interaction terms were used to assess the mediating and moderating effects of the PHD. These analyses were also replicated in another Finnish cohort study (2 834 participants). PRS for BMI was positively associated with baseline BMI and changes in anthropometric measures, except waist circumference (p = 0.12). Significant associations were observed for baseline BMI and WC (p < 0.001), changes in BMI and WC (p = 0.01), and body fat percentage change (p = 0.05). However, the PHD (average score 3.8 points) did not mediate or moderate these relationships. These findings were consistent in the replication cohort. Diet quality assessed with the PHD did not mediate or moderate the associations between genetic susceptibility to obesity and anthropometric measures. This lack of effect may be partly due to low adherence to the PHD and the older age of participants ( > 50 years) at baseline.

This cross-sectional study aims to assess the associations between serum leptin, adiponectin, leptin-to-adiponectin ratio (L/A ratio), and metabolic syndrome (MS) and HOMA-IR in five African-origin populations: Ghana, South Africa, Jamaica, Seychelles, and US. Clinical measures included serum glucose, insulin, adipokines, blood pressure and anthropometric measures. MS was determined using the Harmonized criteria. The final sample included 2087 adults. After adjusting for age, sex, and fat mass, L/A ratio, unlike HOMA-IR, was significantly associated with MS across all sites (p < 0.001). Within sites, L/A ratio was only associated with MS and HOMA-IR in the US (p < 0.001) and South Africa (p < 0.01), respectively. Leptin was associated with MS in South Africa only (p < 0.05) but was significantly associated with HOMA-IR across all five sites and within the US (p < 0.05). Similarly, adiponectin was associated with HOMA-IR in South Africa (p < 0.05) and with MS across all five sites (p < 0.001) and within each site separately, except Ghana. Our study suggests that individuals of the African diaspora in different geographical locations may differ in the determinants of MS. Future studies should investigate the determinants for the disparate relationships between MS, IS and adipokines across different African-origin populations.

While weight loss is recommended for managing hip osteoarthritis (OA), most evidence comes from knee OA studies, limiting its applicability to hip OA. This study addresses this gap by examining the effects of weight loss on hip OA symptoms. A retrospective audit of routinely collected healthcare data from participants enrolled in the Osteoarthritis Healthy Weight for Life (OAHWFL) program, designed for individuals with knee or hip OA. In total, 1714 adults with hip OA were selected from the OAHWFL program; 1408 completed the initial 18-week weight loss phase, while 306 did not complete it. After 18 weeks, participants transitioned to an indefinite weight maintenance phase. Percentage change in body weight from baseline at 18 weeks. Changes in the five subscales of the Hip Disability and Osteoarthritis Outcome Score (HOOS) (Pain, Activity Limitations in Daily Living, Stiffness and Range of Motion, Sports and Recreation Function, and Hip-related Quality of Life) from baseline to 18 weeks. Linear regression, adjusted for sex and baseline values of age, weight, and respective HOOS scores, assessed the relationship between percentage weight change (analyzed as both a continuous variable and in categories: ≤2.5%, >2.5–5.0%, >5.0–7.5%, >7.5–10%, and >10% of baseline weight) and changes in all five HOOS subscales. At baseline, participants had a mean age of 65.14 years, 70% were female, and 78% were individuals with obesity (Body Mass Index ≥30 kg/m2). A statistically significant dose-response relationship was observed between weight loss and improvements in all HOOS subscales, with the greatest improvement in the Hip-related Quality of Life subscale (14.42 points, 31.14%) for >10% weight loss. Our findings suggest that weight loss is associated with reduced symptoms of hip OA, supporting weight loss as an effective treatment strategy for hip OA.
