Background: Obesity's negative impact on young people's health has long been known. The family and its socioeconomic position (SEP) are key determinants in adolescent obesity. However, understanding which familial determinants explain the association remains limited.

Method: The analyses are based on data from the "German Health Interview and Examination Survey for Children and Adolescents" (KiGGS) (1,384 females and 1,332 males aged 11 to 17 years). Logistic regression models explored how familial determinants (family stress, family cohesion, parental smoking, parental sporting activity, and parental overweight) mediated the association between family SEP (parental education, occupational status, and household income) and adolescent obesity.

Results: Significant total effects for the associations between family SEP in childhood and adolescent obesity were found. Splitting the total effect of the family SEP on obesity into direct and indirect effects, all direct effects turned out to be significant. However, all associations involved also indirect effects of familial determinants, except for household income for female adolescents. Parental smoking and overweight were the most relevant mediators for males and females. For male adolescents, parental sporting activity additionally mediated the association between SEP and obesity.

Conclusion: A low SEP in childhood was associated with adolescent obesity. Parental health and health behaviors partly explained the association. For increasing health equality in adolescent health, the consideration of parental health behavior in the planning and implementation of health promotion programs seem to be important.

背景:肥胖对青少年健康的负面影响早已众所周知。家庭及其社会经济地位(SEP)是青少年肥胖的关键决定因素。然而,对哪些家庭决定因素可以解释这种关联的了解仍然有限:分析基于 "德国儿童和青少年健康访谈和检查调查"(KiGGS)的数据(1384 名女性和 1332 名男性,年龄在 11 至 17 岁之间)。逻辑回归模型探讨了家庭决定因素(家庭压力、家庭凝聚力、父母吸烟、父母体育活动和父母超重)如何在家庭SEP(父母教育程度、职业状况和家庭收入)与青少年肥胖之间发挥中介作用:结果:发现儿童时期家庭 SEP 与青少年肥胖之间的关系具有显著的总效应。将家庭 SEP 对肥胖的总效应分为直接效应和间接效应,结果发现所有直接效应都很显著。然而,除女性青少年的家庭收入外,所有关联还涉及家庭决定因素的间接影响。父母吸烟和超重是男女青少年最相关的中介因素。对于男性青少年来说,父母的体育活动也是调节 SEP 与肥胖之间关系的因素:结论:儿童时期的低 SEP 与青少年肥胖有关。父母的健康和健康行为在一定程度上解释了这种关联。为了提高青少年健康的平等性,在规划和实施健康促进计划时考虑父母的健康行为似乎非常重要。

Background: Obesity is a complex multifactorial disease that has been associated with higher morbidity and mortality. Objectives: This study aimed to compare changes in body mass index (BMI) and obesity prevalence between two cross-sectional samples of Brazilian women. Furthermore, retrospective assessments of lifetime body weight changes were explored. Methods: Two independent population-based cross-sectional surveys were conducted in 2003 (first survey) and 2015 (second survey) with women living in the urban area city in southern Brazil. Both surveys had a similar design and included 981 women aged 20-60 years. Mean BMI and the presence of obesity (BMI ≥ 30 kg/m2) were estimated. Additionally, lifetime body weight change was obtained for the retrospective longitudinal assessment. Results: After 12 years, there was a significant increase from 25.9 ± 5.3 kg/m2 to 28.1 ± 6.2 kg/m2 in mean BMI. Between 2003 and 2015, the prevalence of obesity increased by 73% (18.0%; 95% CI: 15.8-20.6 vs. 31.2%; 95% CI: 28.3-34.1; p < 0.001). The means of estimated cumulative body weight gain from 15 to 50 years were 15.2 kg (95% CI: 13.3-17.1) and 17.2 kg (95% CI: 15.5-18.9) in 2003 and 2015, respectively; the greater cumulative difference between the two periods was observed at 40 years of age (3.3 kg). Conclusions: There was a significant increase in the mean BMI and prevalence of obesity between 2003 and 2015. Moreover, women experienced higher body weight gain during their lives in both survey periods, mainly in early adulthood.

背景:肥胖症是一种复杂的多因素疾病,与较高的发病率和死亡率有关。研究目的本研究旨在比较巴西女性两个横断面样本的体重指数(BMI)变化和肥胖症患病率。此外,还对终生体重变化的回顾性评估进行了探讨。调查方法分别于 2003 年(第一次调查)和 2015 年(第二次调查)对居住在巴西南部城市地区的女性进行了两次独立的人口横断面调查。两次调查的设计相似,共包括 981 名 20-60 岁的女性。调查估算了平均体重指数和肥胖程度(体重指数≥ 30 kg/m2)。此外,在回顾性纵向评估中还获得了终生体重变化情况。结果显示12 年后,平均体重指数从 25.9 ± 5.3 kg/m2 显著增至 28.1 ± 6.2 kg/m2。2003 年至 2015 年间,肥胖率增加了 73%(18.0%;95% CI:15.8-20.6 vs. 31.2%;95% CI:28.3-34.1;p <0.001)。2003年和2015年,从15岁到50岁的估计累积体重增加的平均值分别为15.2千克(95% CI:13.3-17.1)和17.2千克(95% CI:15.5-18.9);两个时期的累积差异在40岁时(3.3千克)较大。结论2003 年至 2015 年期间,平均体重指数和肥胖率均有明显增加。此外,在这两个调查期间,女性在一生中体重增加较多,主要是在成年早期。

Overweight and obesity are linked to the severity of infections and the development of chronic conditions among children and adolescents in Ghana. Hence, estimating the current prevalence and its determinants is imperative to guide public health interventions. This review mapped evidence on the prevalence and determinants of overweight and obesity among in-school children and adolescents (aged 5-19 years) in Ghana. Three main databases (PubMed, Central, and JSTOR) were searched for studies conducted in Ghana. Also, the study included only studies published online between 2010 and 2022. The search produced 1214 records, with an additional 23 identified through a search conducted in Google, Google Scholar, the WHO library, HINARI, and institutional repositories. After a thorough screening, 24 records were synthesized. The prevalence of overweight/obesity among the 23,663 in-school children and adolescents in Ghana was 0.5%-47.06%. Females have higher odds of being overweight than males. In addition, lack of nutrition and physical activity (PA) knowledge and low participation in school sports and physical activities exposed in-school children and adolescents in Ghana to overweight and obesity. Consumption of unhealthy foods, late bed, smoking, loneliness, watching television, and playing computer games exposed schoolchildren and adolescents in Ghana to overweight and obesity. There are relatively high levels of overweight and obesity among school-going children and adolescents in Ghana. Addressing sex gaps in PA, ensuring healthy eating, and limiting sedentary lifestyles is the surest way to promote healthy weight among in-school children and adolescents in Ghana.

超重和肥胖与加纳儿童和青少年感染的严重程度和慢性病的发展有关。因此,估算目前的发病率及其决定因素对于指导公共卫生干预措施至关重要。本综述对加纳在校儿童和青少年(5-19 岁)超重和肥胖的流行率及其决定因素的证据进行了分析。研究人员在三个主要数据库(PubMed、Central 和 JSTOR)中搜索了在加纳进行的研究。此外,该研究仅包括 2010 年至 2022 年间在线发表的研究。搜索结果产生了 1214 条记录,通过在 Google、Google Scholar、WHO 图书馆、HINARI 和机构资料库中进行搜索,又发现了 23 条记录。经过全面筛选后,综合了 24 条记录。加纳 23663 名在校儿童和青少年的超重/肥胖率为 0.5%-47.06%。女性超重的几率高于男性。此外,加纳的在校儿童和青少年缺乏营养和体育活动(PA)知识,很少参加学校运动和体育活动,这些都是导致超重和肥胖的原因。食用不健康食品、晚睡、吸烟、孤独、看电视和玩电脑游戏也是加纳在校儿童和青少年超重和肥胖的原因。加纳学龄儿童和青少年的超重和肥胖率相对较高。解决 PA 方面的性别差距、确保健康饮食和限制久坐不动的生活方式是促进加纳在校儿童和青少年健康体重的最可靠方法。

Objective: Genetic variability significantly impacts metabolism, weight gain, and feeding behaviors, predisposing individuals to obesity. This study explored how variations in key genes related to obesity-FOXO3A (forkhead box O3), AMPK (protein kinase AMP-activated), and POMC (proopiomelanocortin)-are associated with extreme obesity (EOB). Methods: We conducted a case-control study with 251 EOB patients and 212 healthy controls with a body mass index (BMI) of less than 25 kg/m2. We genotyped 10 single nucleotide variants (SNVs) using TaqMan-based assays. Results: Four SNVs-rs1536057 in FOXO3A, rs103685 in AMPK, rs934778, and rs6545975 in POMC-were associated with an increased risk of EOB. The strongest association was observed with rs934778 (POMC), which had a maximum odds ratio (OR) of 5.26 (95% CI: 2.86-9.09). While these genetic variations are closely linked to EOB, they do not affect serum glucose, triglycerides, HDL, LDL, BMI, or waist circumference. Conclusions: These findings indicate that factors beyond traditional metabolic pathways, potentially related to feeding behavior or hormonal regulation, may also link these genetic variations to obesity. Further research in a larger sample is essential to validate these findings and explore their potential to guide clinical interventions and public health strategies.

目的基因变异对新陈代谢、体重增加和进食行为有重大影响,易导致肥胖。本研究探讨了与肥胖有关的关键基因--FOXO3A(叉头盒 O3)、AMPK(蛋白激酶 AMP-活化)和 POMC(原髓皮质素)的变异如何与极度肥胖(EOB)相关。研究方法我们对 251 名 EOB 患者和 212 名体重指数(BMI)低于 25 kg/m2 的健康对照者进行了病例对照研究。我们使用基于 TaqMan 的检测方法对 10 个单核苷酸变异体 (SNV) 进行了基因分型。结果显示FOXO3A 中的四个 SNVs-rs1536057、AMPK 中的 rs103685、rs934778 和 POMC 中的 rs6545975 与 EOB 风险增加有关。其中,rs934778(POMC)的关联性最强,其最大比值比 (OR) 为 5.26(95% CI:2.86-9.09)。虽然这些基因变异与 EOB 密切相关,但它们并不影响血清葡萄糖、甘油三酯、高密度脂蛋白、低密度脂蛋白、体重指数或腰围。结论:这些研究结果表明,传统代谢途径之外的因素(可能与进食行为或激素调节有关)也可能将这些基因变异与肥胖联系在一起。要验证这些发现并探索其指导临床干预和公共卫生策略的潜力,必须在更大样本中开展进一步研究。

Background: Visceral adipose tissue (VAT) abnormalities are directly associated with obesity-associated disorders. The underlying mechanisms that confer increased pathological risk to VAT in obesity have not been fully described. Methods: A case-control study was conducted that included 10 women with obesity (36.80 ± 7.39 years, BMI ≥ 30 kg/m2) and 10 women of normal weight (32.70 ± 9.45 years, BMI < 24.9 kg/m2). RNA was extracted from greater omentum biopsies, and, using a DNA microarray, differential transcriptomic expression of VAT in women with obesity was evaluated taking as a reference that of women with normal weight. The differentially expressed genes (DEGs) were classified into functional biological processes and signaling pathways; moreover, the protein-protein interaction (PPI) networks were integrated for a deeper analysis of the pathways and genes involved in the central obesity-associated disorders. The expression of TNF-α, MAPK, and AKT proteins was also quantified in VAT. Results: The VAT of women with obesity had 3808 DEGs, mainly associated with the cellular process of inflammation and carbohydrates and lipid metabolism. Overexpressed genes were associated with inflammatory, metabolic, hormonal, neuroendocrine, carcinogenic, and infectious pathways. Cellular processes related to addictive behaviors were notable. MAPK and PI3K-AKT pathways were overexpressed, and Mapk1 and Akt3 genes were common crossing points among obesity-associated disorders' pathways. The increased expression of MAPK, AKT, and TNF proteins was confirmed in the VAT of women with obesity. Conclusion: VAT confers a complex and blended pathogenic transcriptomic profile in obese patients, where abnormal processes are mainly controlled by activating intracellular signaling pathways that exhibit a high degree of redundancy. Identifying shared cross points between those pathways could allow specific targeting treatments to exert a widespread effect over multiple pathogenic processes.

背景:内脏脂肪组织(VAT)异常与肥胖相关疾病直接相关。肥胖症患者内脏脂肪组织病理风险增加的内在机制尚未完全阐明。研究方法进行了一项病例对照研究,其中包括 10 名肥胖女性(36.80 ± 7.39 岁,体重指数≥ 30 kg/m2)和 10 名体重正常女性(32.70 ± 9.45 岁,体重指数< 24.9 kg/m2)。从大网膜活检组织中提取 RNA,并以体重正常的女性为参照,使用 DNA 微阵列评估肥胖女性 VAT 的差异转录组表达。差异表达基因(DEGs)被归类为功能性生物过程和信号通路;此外,还整合了蛋白质相互作用(PPI)网络,以深入分析与肥胖相关的中心性疾病有关的通路和基因。此外,还量化了VAT中TNF-α、MAPK和AKT蛋白的表达。结果显示肥胖症妇女的血管内皮细胞中有 3808 个 DEGs,主要与炎症、碳水化合物和脂质代谢的细胞过程有关。高表达基因与炎症、代谢、激素、神经内分泌、致癌和感染途径有关。与成瘾行为有关的细胞过程值得注意。MAPK和PI3K-AKT通路过度表达,Mapk1和Akt3基因是肥胖相关疾病通路的共同交叉点。肥胖妇女的血管内皮细胞中证实了 MAPK、AKT 和 TNF 蛋白表达的增加。结论肥胖症患者的增值血管具有复杂和混合的致病转录组特征,其异常过程主要受激活的细胞内信号通路控制,这些通路表现出高度的冗余性。确定这些通路之间的共同交叉点可使特定的靶向治疗对多个致病过程产生广泛的影响。

The expression of TNF-<i>α</i>, MAPK, and AKT proteins was also quantified in VAT. <b>Results:</b> The VAT of women with obesity had 3808 DEGs, mainly associated with the cellular process of inflammation and carbohydrates and lipid metabolism. Overexpressed genes were associated with inflammatory, metabolic, hormonal, neuroendocrine, carcinogenic, and infectious pathways. Cellular processes related to addictive behaviors were notable. MAPK and PI3K-AKT pathways were overexpressed, and Mapk1 and Akt3 genes were common crossing points among obesity-associated disorders' pathways. The increased expression of MAPK, AKT, and TNF proteins was confirmed in the VAT of women with obesity. <b>Conclusion:</b> VAT confers a complex and blended pathogenic transcriptomic profile in obese patients, where abnormal processes are mainly controlled by activating intracellular signaling pathways that exhibit a high degree of redundancy. Identifying shared cross points between those pathways could allow specific targeting treatments to exert a widespread effect over multiple pathogenic processes.</p>","PeriodicalId":16628,"journal":{"name":"Journal of Obesity","volume":"2024 ","pages":"4541071"},"PeriodicalIF":3.8,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11527533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142558006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The importance of early microbial dysbiosis in later development of obesity and metabolic disorders has been a subject of debate. Here we tested cause and effect in mice.

Methods: Germ-free male Swiss Webster mice were colonized in a specific-pathogen-free (SPF) facility at 1 week (1W) and 3 weeks (3W) of age. They were challenged with a high-fat diet and their responses were compared with SPF mice. Gut microbiota was analyzed by 16S rRNA gene sequencing. Moreover, RNA sequencing of the liver was performed on additional 3W and SPF mice on a regular chow diet.

Results: There were no significant differences in weight, food consumption, epididymal fat weight, HbA1c levels, and serum insulin and leptin, whereas the early germ-free period resulted in mice with impaired glucose tolerance. Both the 1W and 3W group peaked 56% (p < 0.05) and 66% (p < 0.01) higher in blood glucose than the SPF control group, respectively. This was accompanied by a 45% reduction in the level of the anti-inflammatory cytokine IL-10 in the 1W mice (p < 0.05). There were no differences in the gut microbiota between the groups, indicating that all mice colonized fully after the germ-free period. Marked effects on hepatic gene expression (728 differentially expressed genes with adjusted p < 0.05 and a fold change ± 1.5) suggested a potential predisposition to a higher risk of developing insulin resistance in the 3W group.

Conclusions: Lack of microbes early in life had no impact on adiposity but led to insulin resistance and altered liver gene expression related to glucose metabolism in mice. The study strongly supports the notion that microbial signaling to the liver in the beginning of life can alter the host's risk of developing metabolic disorder later in life.

目的:早期微生物菌群失调对日后肥胖症和代谢紊乱的重要影响一直是一个争论的话题。在此,我们对小鼠的因果关系进行了测试:无菌雄性瑞士韦伯斯特小鼠在1周龄(1W)和3周龄(3W)时在无特定病原体(SPF)设施中定植。它们接受高脂肪饮食挑战,并将其反应与 SPF 小鼠进行比较。通过 16S rRNA 基因测序分析了肠道微生物群。此外,还对其他 3W 小鼠和以普通饲料为食的 SPF 小鼠的肝脏进行了 RNA 测序:结果:小鼠的体重、食量、附睾脂肪重量、HbA1c水平、血清胰岛素和瘦素没有明显差异,而早期无菌期导致小鼠糖耐量受损。与 SPF 对照组相比,1W 和 3W 组的血糖峰值分别高出 56% (p < 0.05) 和 66% (p < 0.01)。与此同时,1W 组小鼠的抗炎细胞因子 IL-10 水平降低了 45%(p < 0.05)。各组之间的肠道微生物群没有差异,这表明所有小鼠在无菌期后都完全定植。对肝脏基因表达的明显影响(728个差异表达基因,调整后的p < 0.05,折合变化± 1.5)表明,3W组小鼠可能有更高的胰岛素抵抗风险:结论:小鼠在生命早期缺乏微生物不会对脂肪产生影响,但会导致胰岛素抵抗和与葡萄糖代谢相关的肝脏基因表达改变。这项研究有力地支持了这样一种观点,即生命初期向肝脏发出的微生物信号可改变宿主日后患上代谢紊乱的风险。

Relationship of Mitochondrial DNA Oxidation and Content with Metabolic Syndrome and Cardiovascular Risk in Obesity Phenotypes. 线粒体 DNA 氧化和含量与肥胖表型中代谢综合征和心血管风险的关系。
IF 3.8 Q2 ENDOCRINOLOGY & METABOLISM Pub Date : 2024-09-11 eCollection Date: 2024-01-01 DOI: 10.1155/2024/3008093

Objective: Obesity, chronic inflammation, and oxidative stress can influence mitochondrial DNA (mtDNA) content. Our objective was to evaluate the oxidation level and content of mtDNA and its relationship with metabolic parameters in metabolically healthy obese (MHO) compared to metabolically unhealthy obese (MUO) and normal weight (NW) controls.

Materials and methods: We studied 94 NW, 95 MHO, and 97 MUO individuals between 18 and 80 years old. Relative mtDNA content and mtDNA oxidation level (8-oxoguanine, 8-OxoG) were determined in peripheral blood leukocytes by the SYBR Green method of real-time PCR. One-way ANOVA and Tukey test were used to compare biochemical, clinical, and anthropometric characteristics, as well as mtDNA content and 8-OxoG.

Results: A progressive decrease in mtDNA content was observed between NW, MHO, and MUO with significant differences in MUO vs. NW (p: 0.04). An increase in 8-OxoG was observed in MUO patients compared to the other groups (MUO vs. MHO p: 0.01; MUO vs. NW p: 0.04). mtDNA content was directly correlated with HDL-c (p < 0.01) and inversely with waist circumference (p: 0.01) and LDL-c (p: 0.05). mtDNA content decreased, and the oxidation level increased concomitantly with the presence of obesity, the number of MS components, higher coronary risk, and insulin resistance parameters.

Conclusion: MHO presented a similar mtDNA oxidation level to NW and mtDNA content to the MUO, placing the MHO individuals as having an intermediate phenotype. Changes in mtDNA content and oxidation were correlated to the lipid profile related to obesity and/or MS presence, probably associated with oxidative stress and chronic low-grade inflammation.

目的:肥胖、慢性炎症和氧化应激可影响线粒体 DNA(mtDNA)含量:肥胖、慢性炎症和氧化应激会影响线粒体 DNA(mtDNA)的含量。我们的目的是评估代谢健康肥胖(MHO)与代谢不健康肥胖(MUO)和正常体重(NW)对照组相比,线粒体 DNA 的氧化水平和含量及其与代谢参数的关系:我们研究了 94 名 NW、95 名 MHO 和 97 名 MUO,他们的年龄在 18 岁至 80 岁之间。采用 SYBR Green 实时 PCR 法测定外周血白细胞中相对 mtDNA 含量和 mtDNA 氧化水平(8-氧鸟嘌呤,8-OxoG)。采用单因素方差分析和 Tukey 检验比较生化、临床和人体测量特征以及 mtDNA 含量和 8-OxoG:结果:NW、MHO 和 MUO 之间的 mtDNA 含量呈逐渐下降趋势,MUO 与 NW 相比差异显著(p:0.04)。与其他组相比,在 MUO 患者中观察到 8-OxoG 增加(MUO vs. MHO p:0.01;MUO vs. NW p:0.04)。mtDNA 含量与 HDL-c 直接相关(p < 0.01),与腰围(p:0.mtDNA含量的降低和氧化水平的升高与肥胖的存在、MS成分的数量、较高的冠状动脉风险和胰岛素抵抗参数有关:MHO的mtDNA氧化水平与NW相似,mtDNA含量与MUO相似,因此MHO个体属于中间表型。mtDNA含量和氧化的变化与肥胖和/或多发性硬化症相关的血脂谱有关,可能与氧化应激和慢性低度炎症有关。

Beneficial Effects of Capybara Oil Supplementation on Steatosis and Liver Apoptosis in Obese Mice. 补充卡巴巴拉油对肥胖小鼠脂肪变性和肝细胞凋亡的有益影响
IF 3.3 Q2 ENDOCRINOLOGY & METABOLISM Pub Date : 2024-05-27 eCollection Date: 2024-01-01 DOI: 10.1155/2024/7204607

Obesity is a complex chronic disease characterized by excess body fat (adipose) that is harmful to health and has been a major global health problem. It may be associated with several diseases, such as nonalcoholic fatty liver disease (NAFLD). Polyunsaturated fatty acids (PUFA) are lipid mediators that have anti-inflammatory characteristics and can be found in animals and plants, with capybara oil (CO) being a promising source. So, we intend to evaluate the hepatic pathophysiological alterations in C57Bl/6 mice with NAFLD, caused by obesity, and the possible beneficial effects of OC in the treatment of this disease. Eighteen 3-month-old male C57Bl/6 mice received a control or high-fat diet for 18 weeks. From the 15th to the 18th week, the animals received treatment-through orogastric gavage-with placebo or free capybara oil (5 g/kg). Parameters inherent to body mass, glucose tolerance, evaluation of liver enzymes, percentage of hepatic steatosis, oxidative stress, the process of cell death with the apoptotic biomarkers (Bax, Bcl2, and Cytochrome C), and the ultrastructure of hepatocytes were analyzed. Even though the treatment with CO was not able to disassemble the effects on the physiological parameters, it proved to be beneficial in reversing the morphological and ultrastructural damage present in the hepatocytes. Thus, demonstrating that CO has beneficial effects in reducing steatosis and the apoptotic pathway, it is a promising treatment for NAFLD.

肥胖症是一种复杂的慢性疾病,其特点是体内脂肪(脂肪)过多,对健康有害,已成为全球主要的健康问题。它可能与多种疾病相关,如非酒精性脂肪肝(NAFLD)。多不饱和脂肪酸(PUFA)是一种具有抗炎特性的脂质介质,可在动物和植物中发现,其中水豚油(CO)是一种很有前景的来源。因此,我们打算评估由肥胖引起的 C57Bl/6 小鼠非酒精性脂肪肝的肝脏病理生理变化,以及 OC 在治疗这种疾病方面可能产生的有益影响。18只3个月大的雄性C57Bl/6小鼠接受了18周的对照组或高脂肪饮食。从第 15 周到第 18 周,动物通过口腔灌胃接受安慰剂或游离毛冠豚油(5 克/千克)的治疗。对体重、葡萄糖耐量、肝酶评估、肝脏脂肪变性百分比、氧化应激、细胞凋亡生物标志物(Bax、Bcl2 和细胞色素 C)的细胞死亡过程以及肝细胞的超微结构等固有参数进行了分析。尽管使用一氧化碳处理无法消除对生理参数的影响,但事实证明,一氧化碳有利于逆转肝细胞中存在的形态学和超微结构损伤。因此,一氧化碳对减少脂肪变性和细胞凋亡途径有好处,是治疗非酒精性脂肪肝的一种有前途的方法。

A random-effects model was employed to estimate the weighted pooled prevalence of metabolic syndrome in sub-Saharan Africa. Evidence of between-study variance attributed to heterogeneity was assessed using Cochran's Q statistic and the I2 statistic.

The weighted pooled prevalence of metabolic syndrome among individuals with type 2 diabetes mellitus in sub-Saharan Africa was 63.1% (95% CI: 57.9-68.1) when using the NCEP-ATP III 2004 criteria and 60.8% (95% CI: 50.7-70.0) when using the IDF criteria. Subgroup analysis, using NCEP-ATP III 2004 and IDF criteria, revealed higher weighted pooled prevalence among females: 73.5% (95% CI: 67.4-79.5), 71.6% (95% CI: 60.2-82.9), compared to males: 50.5% (95% CI: 43.8-57.2), 44.5% (95% CI: 34.2-54.8), respectively. Central obesity was the most prevalent component of metabolic syndrome, with a pooled prevalence of 55.9% and 61.6% using NCEP-ATP III 2004 and IDF criteria, respectively. There was no statistical evidence of publication bias in both the NCEP-ATP III 2004 and IDF pooled estimates.</p><p><strong>Conclusions: </strong>The findings underscore the alarming prevalence of metabolic syndrome among individuals with type 2 diabetes mellitus in sub-Saharan Africa.

背景:2 型糖尿病和代谢综合征是两个密切相关的公共卫生挑战,在中低收入国家,尤其是撒哈拉以南非洲国家,这两个问题的流行程度已达到令人担忧的程度。因此,本研究旨在确定根据 2004 年美国国家胆固醇教育计划-成人治疗小组(NCEP-ATP III 2004)和/或国际糖尿病联合会(IDF)标准定义的撒哈拉以南非洲 2 型糖尿病患者中代谢综合征及其组成部分的加权汇总患病率:方法:我们进行了一次系统检索,以检索用英语发表的关于撒哈拉以南非洲 2 型糖尿病患者代谢综合征患病率的研究。检索在 PubMed、Embase、Scopus、Google Scholar、African Index Medicus 和 African Journal Online 上进行,检索时间从开始到 2023 年 7 月 31 日。采用随机效应模型估算了撒哈拉以南非洲地区代谢综合征的加权汇总患病率。使用 Cochran's Q 统计量和 I2 统计量评估了异质性导致的研究间差异的证据。乔安娜-布里格斯研究所(Joanna Briggs Institute)的质量评估标准用于评价纳入研究的方法质量。用森林图和表格展示了汇总估计值。用漏斗图和 Egger 回归检验检查发表偏倚:总体而言,共确定了 1421 篇文章,并采用系统综述和元分析首选报告项目(PRISMA)指南进行了评估,最终分析纳入了 30 项符合纳入标准的研究。采用 NCEP-ATP III 2004 标准时,撒哈拉以南非洲 2 型糖尿病患者代谢综合征的加权汇总患病率为 63.1%(95% CI:57.9-68.1),采用 IDF 标准时为 60.8%(95% CI:50.7-70.0)。使用 NCEP-ATP III 2004 和 IDF 标准进行的分组分析显示,女性的加权汇总患病率较高:分别为 73.5%(95% CI:67.4-79.5)和 71.6%(95% CI:60.2-82.9),而男性则分别为 50.5%(95% CI:43.8-57.2)和 44.5%(95% CI:34.2-54.8)。中心性肥胖是代谢综合征中最普遍的组成部分,根据 NCEP-ATP III 2004 和 IDF 标准,其合并患病率分别为 55.9% 和 61.6%。在 NCEP-ATP III 2004 和 IDF 的汇总估计值中,没有统计证据表明存在发表偏差:研究结果表明,在撒哈拉以南非洲地区的 2 型糖尿病患者中,代谢综合征的发病率令人担忧。因此,必须促进生活方式的改变,如定期锻炼和均衡饮食,优先进行常规肥胖筛查,并实施早期干预和强有力的公共卫生措施,以减轻与中心性肥胖相关的风险。

Central obesity was the most prevalent component of metabolic syndrome, with a pooled prevalence of 55.9% and 61.6% using NCEP-ATP III 2004 and IDF criteria, respectively. There was no statistical evidence of publication bias in both the NCEP-ATP III 2004 and IDF pooled estimates.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;The findings underscore the alarming prevalence of metabolic syndrome among individuals with type 2 diabetes mellitus in sub-Saharan Africa. Therefore, it is essential to promote lifestyle modifications, such as regular exercise and balanced diets, prioritize routine obesity screenings, and implement early interventions and robust public health measures to mitigate the risks assoc","PeriodicalId":16628,"journal":{"name":"Journal of Obesity","volume":"2024 ","pages":"1240457"},"PeriodicalIF":3.8,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10896656/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139972215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obesity and diabetes are a problem of modern medicine. Although the environmental factors contributing to the development of these diseases are widely known, research into genetic factors is still ongoing. At the same time, the role of inflammation in the pathophysiology of obesity and diabetes is increasingly emphasized. Therefore, the purpose of this study was to investigate the influence of two selected polymorphisms (rs1800795 and rs3842729) on the development of obesity and type 2 diabetes. In this study, 118 participants were examined, including a control group (nonobese and nondiabetic group), an obese group, and a diabetic group. Genotype analysis was performed using the PCR-RFLP method. It has been shown that in patients with the G/G genotype within the rs1800795 polymorphism (IL6), the chance of developing type 2 diabetes is several times lower compared to patients with the G/C and C/C genotypes. However, the rs3842729 polymorphism (INS) does not directly affect the risk of obesity or type 2 diabetes (T2D), although elevated insulin concentrations have been observed in obese and diabetic patients. These results confirm the impact of the rs1800795 polymorphism on the development of diabetes; however, this relationship is more complex and requires further research on other factors.

肥胖症和糖尿病是现代医学的一个难题。尽管导致这些疾病发生的环境因素已广为人知,但对遗传因素的研究仍在继续。与此同时,炎症在肥胖症和糖尿病病理生理学中的作用也日益受到重视。因此,本研究旨在调查两个选定的多态性(rs1800795 和 rs3842729)对肥胖和 2 型糖尿病发病的影响。本研究共调查了 118 名参与者,包括对照组(非肥胖组和非糖尿病组)、肥胖组和糖尿病组。基因型分析采用 PCR-RFLP 方法进行。研究表明,与 G/C 和 C/C 基因型患者相比,rs1800795 多态性(IL6)G/G 基因型患者罹患 2 型糖尿病的几率要低数倍。然而,rs3842729 多态性(INS)并不直接影响肥胖或 2 型糖尿病(T2D)的风险,尽管在肥胖和糖尿病患者中观察到胰岛素浓度升高。这些结果证实了 rs1800795 多态性对糖尿病发病的影响;然而,这种关系更为复杂,需要进一步研究其他因素。
