The Impact

Background. The World Health Organization European Childhood Obesity Surveillance Initiative (COSI) conducted examinations in 6–9-year-old children from 16 countries in the first two rounds of data collection. Allowing participating countries to adhere to their local legal requirements or adapt to other circumstances required developing a flexible protocol for anthropometric procedures. Objectives. (1) Review intercountry variation in types of clothing worn by children during weight and height measurements, clothes weight adjustments applied, timing of the survey, and duration of data collection; (2) assess the impact of the observed variation in these practices on the children’s weight or body mass index (BMI) outcome measures. Results. The relative difference between countries’ unadjusted and clothes-adjusted prevalence estimates for overweight was 0.3–11.5%; this figure was 1.4–33.3% for BMI-for-age Z-score values. Monthly fluctuations in mean BMI-for-age Z-score values did not show a systematic seasonal effect. The majority of the monthly BMI-for-age Z-score values did not differ statistically within a country; only 1–3 monthly values were statistically different within some countries. Conclusions. The findings of the present study suggest that the built-in flexibility in the COSI protocol concerning the data collection practices addressed in the paper can be kept and thus do not necessitate a revision of the COSI protocol.

The Impact

Background and Aims: The impact of body mass index on complications and survival in patients undergoing esophagectomy has been extensively studied with conflicting results. In this study, we assess the impact of body mass index on complications and survival following surgery for esophageal and gastro-esophageal-junction cancer in a Danish population. Material and Methods: We identified 285 consecutive patients, who underwent curative-intended treatment for esophageal and gastro-esophageal-junction cancer in the period 2003–2010. We manually reviewed the electronic medical records of all patients included in the study. Body mass index was calculated as weight in kilograms divided by height in meters squared. We grouped patients according to their body mass index, using the World Health Organization definition, as underweight (body mass index < 18.5 kg/m2), normal weight (body mass index: 18.5–24.9 kg/m2), overweight (body mass index: 25–29.9 kg/m2), and obese (body mass index ⩽ 30 kg/m2). Results: Median age at surgery was 65 years (range: 27–84 years), of which 207 (72.6%) were males. Patients with the lowest body mass index and the obese patients seemed to have a higher frequency of minor complications. Anastomotic leakage occurred in less than 10% of the patients and was equally distributed across the groups as was the other major complications. There were no differences in the 1-, 2-, or 5-year survival rates between the four body mass index groups after adjustment for possible confounders. Five-year survival rates for the four body mass index groups were 31.8%, 28.7%, 27.9%, and 26.1%, respectively. Conclusion: Body mass index over 30 or under 18.5 does not seem to affect survival rates or the presence of serious postoperative complications following esophagectomy in patients with esophageal and gastro-esophageal-junction cancers not receiving neoadjuvant oncological treatment.

Objective: Childhood obesity is a growing concern as the World Health Organization (WHO) states that ~10% of adolescents worldwide are overweight or obese. This condition is the reflex of energy imbalance between the calories consumed and those expended. Sex-related responses associated with dyslipidemia, hormonal alterations, and neuro-humoral disruptions in childhood obesity are the focus of the present investigation.Methods: Ninety-two Brazilian adolescents were enrolled and divided between obese and eutrophic groups. Obesity was assessed using body mass index Z-score according to age and weight. Anthropometrical analyses, blood pressure, blood lipids, metabolism-regulating hormones, and neuropeptides were carried out.Results: Systolic blood pressure was higher in female and male patients with obesity. Obese females presented alterations in lipid profile and an augment of cardiovascular disease prediction ratios TC/HDL, TG/HDL, LDL/HDL, and VLDL/HDL. The levels of leptin, GIP, and neuropeptide showed sex-dimorphism in obesity. The obese adolescents presented increased levels of circulating insulin, c-peptide, amylin, glucagon, and GLP-1. Correlation analysis showed significant linearity between body mass index, blood pressure, lipids, lipoproteins, hormones, and neuropeptides content.Conclusions: Our data support an existing link associating hypertension, dyslipidemia, and neuro-hormonal imbalance in childhood obesity. We also described a sex-dependent pattern in childhood obesity-associated dyslipidemia and blood pressure in female patients with obesity solely.

Abstract Background Although obesity is a well-recognised risk factor for cardiovascular disease (CVD), the impact of long-term body mass index (BMI) changes in overweight or obese adults, on the risk of heart failure, CVD and mortality has not been quantified. Methods This population-based cohort study used routine UK primary care electronic health data linked to secondary care and death-registry records. We identified adults who were overweight or obese, free from CVD and who had repeated BMI measures. Using group-based trajectory modelling, we examined the BMI trajectories of these individuals and then determined incidence rates of CVD, heart failure and mortality associated with the different trajectories. Cox-proportional hazards regression determined hazards ratios for incident outcomes. Results 264,230 individuals (mean age 49.5 years (SD 12.7) and mean BMI 33.8 kg/m2 (SD 6.1)) were followed-up for a median duration of 10.9 years. Four BMI trajectories were identified, corresponding at baseline, with World Health Organisation BMI classifications for overweight, class-1, class-2 and class-3 obesity respectively. In all four groups, there was a small, stable upwards trajectory in BMI (mean BMI increase of 1.06 kg/m2 (± 3.8)). Compared with overweight individuals, class-3 obese individuals had hazards ratios (HR) of 3.26 (95% CI 2.98–3.57) for heart failure, HR of 2.72 (2.58–2.87) for all-cause mortality and HR of 3.31 (2.84–3.86) for CVD-related mortality, after adjusting for baseline demographic and cardiovascular risk factors. Conclusion The majority of adults who are overweight or obese retain their degree of overweight or obesity over the long term. Individuals with stable severe obesity experience the worst heart failure, CVD and mortality outcomes. These findings highlight the high cardiovascular toll exacted by continuing failure to tackle obesity.

The Impact

Abstract Background Total knee arthroplasty is known to successfully alleviate pain and improve function in endstage knee osteoarthritis. However, there is some controversy with regard to the influence of obesity on clinical benefits after TKA. The aim of this study was to investigate the impact of body mass index (BMI) on improvement in pain, function and general health status following total knee arthroplasty (TKA). Methods A single-centre retrospective analysis of primary TKAs performed between 2006 and 2016 was performed. Data were collected preoperatively and 12-month postoperatively using WOMAC score and EQ-5D. Longitudinal score change was compared across the BMI categories identified by the World Health Organization. Results Data from 1565 patients [mean age 69.1, 62.2% women] were accessed. Weight distribution was: 21.2% BMI < 25.0 kg/m2, 36.9% BMI 25.0–29.9 kg/m2, 27.0% BMI 30.0–34.9 kg/m2, 10.2% BMI 35.0–39.9 kg/m2, and 4.6% BMI ≥ 40.0 kg/m2. All outcome measures improved between preoperative and 12-month follow-up (p < 0.001). In pairwise comparisons against normal weight patients, patients with class I-II obesity showed larger improvement on the WOMAC function and total score. For WOMAC pain improvements were larger for all three obesity classes. Conclusions Post-operative improvement in joint-specific outcomes was larger in obese patients compared to normal weight patients. These findings suggest that obese patients may have the greatest benefits from TKA with regard to function and pain relief one year post-op. Well balanced treatment decisions should fully account for both: Higher benefits in terms of pain relief and function as well as increased potential risks and complications.

Aim. To investigate physical development of children in Voronezh region in different age groups in 2011-2014 in comparison with the regional studies data in 1997-1999. Methods. The study was performed on 5644 children aged 1-18 years of health groups I and II in comparison with the data of 10 247 children aged 1-14 years examined in 1997-1999. Body height, weight and body mass index Z-scores, calculated using WHO AnthroPlus software, were evaluated. Results. Children’s Z-score values for body height in 2011-2014 were higher than in 1997-1999 in all age groups and at the age of 1-9 years these values exceeded World Health Organization (WHO) standards. Girls’ height approached the standards in 10-14 and 15-18 years, and boys’ height - in 15-18 years. Body weight of children aged 2-8 years was higher than the regional data in 1997-1999 and WHO standards approaching them at the age of 9. Body mass index increase compared to WHO standards was revealed in children aged 1-4 years (p=0.000), and in 2011-2014 the reported differences were less prominent than in 1997-1999. In 2011-2014 among 15-18-years-old girls the shift of body mass index values to the lack of body weight was noted, in 1997-1999 the same changes were found out for 10-14-years-old girls. Conclusion. In 2011-2014 specific attention was required to be paid to physical development of children at the age from 1 to 4 years due to overweight risk of and girls aged 15-18 years due to probable underweight risk.

Abstract Background Triglyceride glucose-body mass index (TyG-BMI) has been recommended as an alternative indicator of insulin resistance. However, the association between TyG-BMI and pre-diabetes remains to be elucidated. Methods More than 100,000 subjects with normal glucose at baseline received follow-up. The main outcome event of concern was pre-diabetes defined according to the diagnostic criteria recommended by the American Diabetes Association (ADA) in 2018 and the World Health Organization (WHO) in 1999. A Cox proportional hazard regression model was used to evaluate the role of TyG-BMI in identifying people at high risk of pre-diabetes. Results At a mean observation period of 3.1 years, the incidence of pre-diabetes in the cohort was 3.70 and 12.31% according to the WHO and ADA diagnostic criteria for pre-diabetes, respectively. The multivariate Cox regression analysis demonstrated that TyG-BMI was independently positively correlated with pre-diabetes, and there was a special population dependence phenomenon. Among them, non-obese people, women and people under 50 years old had a significantly higher risk of TyG-BMI-related pre-diabetes (P-interaction< 0.05). Conclusions These findings suggest that a higher TyG-BMI significantly increases an individual’s risk of pre-diabetes, and this risk is significantly higher in women, non-obese individuals, and individuals younger than 50 years of age.

Obesity In Children

Currently in the world the main diagnostic parameter for assessing obesity is the magnitude of body mass index. In children, taking into account the growth and body weight indicators that dynamically change as the child grows up, it is common to use not absolute, but relative values of body mass index percentiles or standard deviations. The lecture examined various systems and methods for assessing the physical development of children in the world and in Russia domestic ones, R.N. Dorokhova and I.I. Bakhraha, World Health Organization (WHO), International Group for the Study of Obesity. A comparative analysis of the existing systems and the validity of the currently adopted Federal recommendations on the diagnosis of obesity in children based on the recommendations of WHO has been carried out.

Abstract Background Exposures to human immunodeficiency (HIV) and antiretroviral therapy in utero may have adverse effects on infant growth. Among children born in Denmark and aged 0–5 years, we aimed to compare anthropometric outcomes in HIV-exposed but uninfected (HEU) children with those in children not exposed to HIV. Methods In a nationwide register-based study we included all singleton HEU children born in Denmark in 2000–2016. HEU children were individually matched by child sex, parity, and maternal place of birth to 5 singleton controls born to mothers without HIV. Weight-for-age z (WAZ) scores, length-for-age z (LAZ) scores, and weight-for-length or body mass index–for–age z scores were generated according to the World Health Organization standards and the Fenton growth chart for premature infants. Differences in mean z scores were analyzed using linear mixed models, both univariate and adjusted for social and maternal factors. Results In total, 485 HEU children and 2495 HIV-unexposed controls were included. Compared with controls, HEU children were smaller at birth, with an adjusted difference in mean WAZ and LAZ scores of −0.29 (95% confidence interval [CI], −.46 to −.12) and −0.51 (95% CI, −.71 to −.31), respectively (both P ≤ .001). Over time, there was a trend toward increasing WAZ and LAZ scores in HEU children, and there was no significant difference in adjusted WAZ scores after age 14 days (−0.13 [95% CI, −.27 to .01]; P = .07) and LAZ scores after age 6 months (−0.15 [95% CI, −.32 to .02]; P = .08). Conclusion Compared with a matched control group, HEU children were smaller at birth, but this difference decreased with time and is not considered to have a negative effect on the health and well-being of HEU children during early childhood.
