Cardiovascular rhythmicity in overweight and obese children / Ritmicidade cardiovascular em crianças com sobrepeso e obesidade

Abstract Introduction: Obesity is thought to play a role in the disruption of cardiac rhythmicity in obese children, but this is mostly an unexplored field of investigation. We aimed to evaluate the impact of overweight and obesity on circadian and ultradian cardiovascular rhythmicity of prepubertal children, in comparison with normal weight counterparts. Methods: We performed a cross sectional study of 316 children, followed in the birth cohort Generation XXI (Portugal). Anthropometrics and 24-hour ambulatory blood pressure were measured and profiles were examined with Fourier analysis for circadian and ultradian blood pressure (BP) and heart rate (HR) rhythms. Results: Overweight/obese children presented more frequently a non-dipping BP pattern than normal weight counterparts (31.5% vs. 21.6%, p = 0.047). The prevalence of 24-hour mean arterial pressure (MAP) and 8-hour HR rhythmicity was significantly lower in obese children (79.3% vs. 88.0%, p = 0.038 and 33.3% vs. 45.2%, p = 0.031, respectively). The prevalence of the remaining MAP and HR rhythmicity was similar in both groups. No differences were found in the median values of amplitudes and acrophases of MAP and HR rhythms. Discussion: The alterations found in rhythmicity suggest that circadian and ultradian rhythmicity analysis might be sensitive in detecting early cardiovascular dysregulations, but future studies are needed to reinforce our findings and to better understand their long-term implications.

Resumo Introdução: Acredita-se que a obesidade desempenhe um papel na desregulação da ritmicidade cardíaca em crianças obesas, mas esse é um campo de investigação ainda pouco explorado. O objetivo deste trabalho foi avaliar o impacto do sobrepeso e da obesidade na ritmicidade cardiovascular circadiana e ultradiana de crianças pré-púberes, em comparação com crianças com peso normal. Métodos: Realizamos um estudo transversal com 316 crianças, acompanhadas na coorte de nascimentos Geração XXI (Portugal). Foram medidos dados antropométricos e a pressão arterial ambulatorial de 24 horas, e os perfis foram examinados com uma análise de Fourier para ritmos circadianos e ultradianos de pressão arterial (PA) e frequência cardíaca (FC). Resultados: Crianças com sobrepeso/obesidade apresentaram mais frequentemente um padrão de PA não-dipper em comparação com crianças com peso normal (31,5% vs. 21,6%; p = 0,047). A prevalência da pressão arterial média (PAM) de 24 horas e da ritmicidade da FC de 8 horas foi significativamente menor em crianças obesas (79,3% vs. 88,0%; p = 0,038 e 33,3% vs. 45,2%; p = 0,031, respectivamente). A prevalência das restantes ritmicidades da PAM e da FC foi semelhante em ambos os grupos. Não foram encontradas diferenças nos valores medianos das amplitudes e acrofases dos ritmos de PAM e FC. Discussão: As alterações encontradas na ritmicidade sugerem que a análise da ritmicidade circadiana e ultradiana pode ser sensível na detecção de desregulações cardiovasculares precoces, mas são necessários novos estudos para reforçar nossos achados e entender melhor suas implicações a longo prazo.

Morbilidad oculta por hipertensión arterial en adolescentes. Importancia del monitoreo ambulatorio de presión arterial / Hidden morbidity due to arterial hypertension in adolescents. Importance of ambulatory blood pressure monitoring

El diagnóstico de un niño o adolescente como hipertenso no es tarea fácil. El principal medio para el diagnóstico de hipertensión arterial sigue siendo la presión arterial tomada en el consultorio, pero por su escasa reproducibilidad, este método tiene algunas limitaciones. Existen otros menos usados en el medio pediátrico, pero más reproducibles y confiables, como el monitoreo ambulatorio de la presión arterial, el cual permite disminuir el subdiagnóstico de hipertensión arterial. La investigación se realizó a partir de un pesquisaje efectuado con el objetivo de identificar la morbilidad oculta de hipertensión arterial en adolescentes con exceso de peso, en el área de salud del Policlínico «Chiqui Gómez Lubián», Santa Clara, Villa Clara. El caso reviste importancia para la Atención Primaria de Salud, promueve la utilización de un método diagnóstico que mejora la correcta clasificación y tratamiento de la hipertensión en edades tempranas para contribuir a la prevención de complicaciones posteriores

Diagnosing a child or an adolescent as hypertensive is not an easy task. The main way to diagnose arterial hypertension continues to be at the doctor´s office, but due to its poor reproducibility, this method has some limitations. There are other less used methods in the pediatric setting, but are more reproducible and reliable, such as ambulatory blood pressure monitoring, which makes it possible to reduce the underdiagnosis of arterial hypertension. We present a case of a male adolescent who was detected during a screening, with the objective of identifying hidden morbidity of arterial hypertension in overweight adolescents, in the health area at "Chiqui Gómez Lubián" Polyclinic, in Santa Clara, Villa Clara. The case is of great important for primary health care, promotes the use of a diagnosis method that improves the correct classification and treatment of hypertension at an early age and contributes to the prevention of subsequent complications

Ecological determinants of obesity risk in Mexican infants: a scoping review / Determinantes ecológicos de riesgo de obesidad en lactantes mexicanos: una revisión de alcance

Abstract Background: Childhood obesity is a multifactorial disease. Most of these factors start to develop before birth and worsen throughout life. Therefore, prevention efforts should begin in the first 1000 days of life. This study aimed to quantify published studies on risk factors according to the Six-Cs model of childhood obesity (cell, child, clan, culture, community, and country) and determine which of them have been related to anthropometric indicators of overweight or obesity in children under 2 years of age in Mexico. Methods: A systematic scoping review (PRISMA-ScR) was performed. PubMed, Scopus, and EBSCOhost databases were reviewed. Results: We found that 88% of the studies were observational. The child and family spheres were the most studied, individually and as a whole. The least studied were community, culture, and country. The main risk factors related to obesity indicators were high birth weight, birth by cesarean section, and inadequate feeding practices, in addition to mothers with obesity and those who underestimate their child's weight, stressful parenting style, and food insecurity in the home, together with living in urban areas, family income, and beliefs about preference for ultra-processed products. Conclusion: In Mexico, the study of obesity in early childhood is emerging at the research level. However, further efforts are required to close the knowledge gap at the socioecological level to design evidence-based interventions and reduce early obesity.

Resumen Introducción: La obesidad infantil es una enfermedad multifactorial en la que varios factores comienzan a desarrollarse antes del nacimiento y se agravan a lo largo de la vida. Por ello, los esfuerzos de prevención para evitar su desarrollo deben comenzar durante los primeros 1000 días de vida. Los objetivos de este estudio fueron cuantificar los estudios publicados sobre factores de riesgo según el modelo de obesidad infantil de las 6-Cs (célula, niño, familia, cultura, comunidad y país) y determinar cuáles de ellos se han relacionado con indicadores de sobrepeso u obesidad en niños menores de 2 años en México. Métodos: Se realizó una revisión sistemática de alcance (PRISMA-ScR). Se revisaron las bases de datos de PubMed, Scopus y EBSCOhost. Resultados: Se encontró que el 88% de los estudios fueron de tipo observacional. La esfera niño y familia fueron las más abordadas, tanto individual como en conjunto. Las menos estudiadas fueron comunidad, cultura y país. Los principales factores de riesgo relacionados con indicadores de obesidad fueron alto peso al nacer, nacer por vía cesárea y prácticas inadecuadas de alimentación; además, madres con obesidad y que subestiman el peso del hijo, estilo de crianza presionante e inseguridad alimentaria en el hogar, aunado el vivir en zonas urbanas, ingreso económico-familiar y creencias sobre la preferencia por productos ultraprocesados. Conclusiones: En México, el estudio de obesidad durante los primeros 1000 días es emergente a nivel de investigación, pero se requiere continuar con el esfuerzo para cerrar la brecha de conocimiento a nivel socio-ecológico, diseñar intervenciones basadas en la evidencia y disminuir la obesidad temprana.

Obesity in Adolescents: Prevalence and Association with Sociodemographic and Lifestyle Factors

Introduction: Overweight and obesity has become a worldwide epidemic and is a growing public health concern. The increase in prevalence and severity of obesity among children and adolescents has been attributed largely to behavioral factors such as changing eating habits and sedentary lifestyles. Objective: To determine prevalence of obesity and abdominal obesity among adolescents and its association with sociodemographic factors and lifestyle. Methods: Present cross-sectional study was conducted in the urban field practice area under the Community Medicine Department of LLRM Medical College, Meerut, among 872 adolescents. All localities in the field area were covered and house to house survey was done. Questions were asked about eating patterns, physical activity and sedentary lifestyle. Data was collected and analyzed using appropriate statistical tests. Results: The prevalence of overweight and obesity was 17.43, 6.88%, respectively. Obesity was significantly higher among females, those who indulged in unhealthy eating habits were physically inactive, watched television for a longer duration and ate junk while watching television. Conclusion: In the present study, we found that high junk food consumption and a sedentary lifestyle were found to be significantly associated with childhood overweight/obesity. As a result, timely interventions should be taken to improve awareness about healthy lifestyle behavior to prevent obesity and its complications among adolescents.

Mastication in overweight and obese children: A comparative cross-sectional study

Abstract Objective: The objective of this study was to analyze masticatory characteristics in children from 7 to 10 years, and to compare these characteristics among normal weight, overweight and obese children. Methods: This is a cross-sectional study, conducted in northeast Brazil, with a sample of 160 children, aged 7 to 10 years. The authors evaluated: nutritional and dental status; food intake; masticatory parameters and orofacial myofunctional characteristics. The children were divided according to nutritional status into normal weight (n = 101), overweight (n = 33) and obesity (n = 26) groups. Results: The results showed that Obese children had a larger bite size (g) (median = 6.0, Q1-Q3 = 4.0-9.0, p = 0.049) and performed fewer masticatory sequences (median = 3.0, Q1-Q3 = 2.0-3.2, p = 0.024) than children with normal weight (median = 5.0, Q1-Q3 = 4.0-7.0; median = 4.0, Q1-Q3 = 3.0-5.0). Furthermore, obese children finished feeding in a shorter time (s) (median = 62.5, Q1-Q3 = 50.5-70.0, p = 0.039) than normal weight children (median = 66.0, Q1-Q3 = 56.5-78.0) and overweight children (median = 66.0, Q1-Q3 = 58.0-81.5). Conclusions: The present results suggest that obese children present changes in mastication, evidenced by larger bite-size, performing fewer masticatory sequences and rapid mastication, which may contribute to increased food consumption and the development of excess weight.

Overweight status, abdominal circumference, physical activity, and functional constipation in children

SUMMARY OBJECTIVE: The aim of this study was to assess the prevalence of functional constipation and its relationship with the food intake, overweight status, and physical activity of children. METHODS: This cross-sectional study included students from two public schools in the municipality of Osasco, which is located in the metropolitan area of São Paulo. Functional constipation was diagnosed if the clinical manifestations of the Rome IV criteria were present for more than 2 months. A 24-h recall survey was used to determine the daily food intake. Weight, height, abdominal circumference, and bioelectrical impedance were used to evaluate the weight status. Active commuting to school and physical activity scores were assessed using a questionnaire that has been validated in Brazil. RESULTS: A total of 452 children, aged 6-12 years, were evaluated. Functional constipation was observed in 22.3% of participants. A greater abdominal circumference was associated with functional constipation in girls (p=0.036) in the bivariate analysis but not in the logistic regression model. Boys with functional constipation consumed higher quantities of fats (p=0.041). There was no statistically significant relationship between functional constipation and overweight status (44.6 and 34.5% of children with and without constipation, respectively; p=0.083) and active commuting to school (48.5 and 56.7% of children with and without constipation, respectively; p=0.179). CONCLUSION: Functional constipation was associated with a greater abdominal circumference in girls in the bivariate analysis, however, without association in the logistic regression model. Boys with functional constipation consumed higher quantities of fat. No association was found between functional constipation, overweight status, and physical activity.

Homocysteine concentrations in overweight children and adolescents

SUMMARY OBJECTIVE: The aim of this study was to describe homocysteine concentrations in overweight and obese children and adolescents and relate them to blood pressure levels, renal function, and insulin resistance. METHODS: This is a cross-sectional and observational study with 64 overweight children and adolescents (mean age: 11.6±3.5 years) in outpatient follow-up. The following parameters were evaluated: body mass index z-score, waist-to-height circumference ratio, pubertal stage, blood pressure, serum homocysteine, glycemia, insulin, lipid profile, renal function, high-sensitivity C-reactive protein, microalbuminuria, and creatinuria. Statistical analysis: analysis of variance and logistic regression (dependent variable: homocysteine) (p<0.05). RESULTS: The mean body mass index z-score was 2.9±1.1. The mean homocysteine concentrations were 8.6±2.2 μmol/L (10th and 90th percentiles: 6.6 and 11.2 μmol/L, respectively), with no difference when compared with children with severe obesity and obesity/overweight (p=0.431). High values of waist-to-height ratio (93.8%), systolic blood pressure (18.8%), diastolic blood pressure (12.5%), glycemia (4.7%), low-density lipoprotein cholesterol (31.1%), triglycerides (35.9%), non-high-density lipoprotein cholesterol (34.4%), and microalbuminuria (21.9%) were obtained. The mean glomerular filtration rate was 122.9±24.6 mL/min/1.73 m². Homocysteine concentrations were not associated with any of the studied variables (R²=0.095). CONCLUSION: Homocysteine concentrations in overweight children and adolescents (mean 8.6±2.2 μmol/L) were not associated with body mass index z-score, blood pressure, renal function, and insulin resistance.

Influence of rs2587552 polymorphism of DRD2 gene on the effect of a childhood obesity intervention: A prospective, parallel-group controlled trial / 北京大学学报(医学版)

OBJECTIVE@#To explore the association between rs2587552 polymorphism (has a strong lin-kage disequilibrium with rs1800497 which had been found in many studies to be related to obesity, r2=0.85) of DRD2 gene and the effect of a childhood obesity intervention in Chinese population, and provide a scientific basis for future personalized childhood obesity intervention based on genetic background.@*METHODS@#From a multi-center cluster randomized controlled trial studying the effect of a childhood obesity intervention, we enrolled 382 children from 8 primary schools (192 and 190 children from intervention and control groups, respectively) in Beijing as study subjects. Saliva was collected and DNA was extracted to detect the rs2587552 polymorphism of DRD2 gene, and the interactions between the gene and study arms on childhood obesity indicators [including body weight, body mass index (BMI), BMI Z-score, waist circumference, hip circumference, waist-to-hip ratio, waist-to-height ratio, and body fat percentage] were analyzed.@*RESULTS@#No association was found between rs2587552 polymorphism and the changes in hip circumference or body fat percentage in the intervention group (P>0.05). However, in the control group, children carrying the A allele at DRD2 rs2587552 locus showed a greater increase in hip circumference and body fat percentage compared with those not carrying A allele (P < 0.001). There were interactions between rs2587552 polymorphism of DRD2 gene and study arms on the changes in hip circumference and body fat percentage (P=0.007 and 0.015, respectively). Compared with the control group, children in the intervention group carrying the A allele at DRD2 rs2587552 locus showed decrease in hip circumference by (-1.30 cm, 95%CI: -2.25 to -0.35, P=0.007) and decrease in body fat percentage by (-1.34%, 95%CI: -2.42 to -0.27, P=0.015) compared with those not carrying A allele. The results were consistent between the dominant model and the additive model (hip circumfe-rence: -0.66 cm, 95%CI: -1.28 to -0.03, P=0.041; body fat percentage: -0.69%, 95%CI: -1.40 to 0.02, P=0.056). No interaction was found between rs2587552 polymorphism and study arms on the changes in other childhood obesity-related indicators (P>0.05).@*CONCLUSION@#Children carrying the A allele at rs2587552 polymorphism of DRD2 gene are more sensitive to intervention and showed more improvement in hip circumference and body fat percentage after the intervention, suggesting that future personalized childhood obesity lifestyle intervention can be carried out based on the rs2587552 polymorphism of DRD2 gene.

Obesidade infantil em tempos de pandemia: uma revisão integrativa / Childhood obesity in pandemic times: an integrative review / Obesidad infantil en tiempos de pandemia: una revisión integradora

A obesidade é considerada um dos maiores problemas de saúde pública mundial, sendo caracterizada como uma epidemia global, e durante a pandemia de COVID-19, o isolamento social e as mudanças nos hábitos de vida podem ter influenciado para o aumento dos índices de obesidade em crianças e adolescentes. Assim, o objetivo do estudo é analisar na literatura de que forma a pandemia de COVID-19 pode ter influenciado no aumento da obesidade infantil. Trata-se de uma revisão integrativa da literatura, com busca feita nas bases de dados Cinahl, PubMed e Scopus, com uso de descritores e booleanos aplicados em cada base de dados. Ao todo 14 estudos foram incluídos nesta revisão. A maioria dos estudos tinha ênfase avaliação de intervenções, bem como comparação das taxas de obesidade antes e durante a pandemia, e os efeitos dessas mudanças a longo prazo. Além de enfatizar sobre a participação dos pais e a construção de políticas públicas no combate à epidemia global de obesidade infantil. A pandemia contribuiu para o aumento de casos de sobrepeso e obesidade, bem como agravou os casos de crianças que já apresentavam tais características. Desta forma compreender sobre a situação desse problema de saúde, após um longo período de confinamento, pode auxiliar e engajar os profissionais da saúde na construção e estabelecimento de estratégias no combate da obesidade infantil e incentivar a participação dos pais na promoção de mudanças no estilo de vida.

Serum amyloid A in children and adolescents: association with overweight and carotid intima-media thickness

ABSTRACT Objective To compare serum amyloid A concentrations between overweight and eutrophic children and adolescents and to relate it to lipid profiles, glucose tolerance, and carotid intima-media thickness. Methods One hundred children and adolescents (mean age: 10.8±3.16 years) were included and divided into two groups: overweight and non-overweight. The following were evaluated: Z-score body mass index, carotid intima-media thickness, lipid metabolism biomarkers (lipid profile and apolipoproteins A1 and B), inflammatory biomarkers (ultra-sensitive C-reactive protein and serum amyloid A), and glucose homeostasis model assessment of insulin resistance. Results The groups were homogeneous in age, sex, and pubertal stage. Higher levels of triglycerides, apolipoprotein B, homeostasis model assessment of insulin resistance, ultrasensitive C-reactive protein, serum amyloid A, and carotid intima-media thickness were observed in the overweight group. In the multivariate analysis, age (OR=1.73; 95%CI: 1.16-2.60, p=0.007), Z-score body mass index (OR=3.76; 95%CI: 1.64-8.59, p=0.002), apolipoprotein-B (OR=1.1; 95%CI: 1.01-1.2, p=0.030), and carotid intima-media thickness (OR=5.00; 95%CI: 1.38-18.04, p=0.014) were independently associated with serum amyloid A levels above the fourth quartile of the studied sample (>9.4mg/dL). Conclusion Overweight children and adolescents had higher serum amyloid A concentrations than eutrophic children. There was an independent association between higher concentrations of serum amyloid A and Z-score, body mass index, apolipoprotein B, and carotid intima-media thickness, indicating the importance of this inflammatory biomarker in identifying the early risk of atherosclerosis.

COVID-19 lockdown effects on the anthropometrics, aerobic capacity, muscle function and metabolic control in children and adolescents with overweight and obesity

Abstract Objective: The lockdown due to a novel Coronavirus (COVID-19) pandemic negatively impacted the daily physical activity levels and sedentary behavior of children and adolescents. The purpose of this study was to determine the effects of lockdown on the anthropometric measurements, aerobic capacity, muscle function, lipid profile and glycemic control in overweight and obese children and adolescents. Methods: 104 children and adolescents with overweight and obesity were divided in a non-lock-down group (NL) (n = 48) and a lockdown group (L) (n = 56). Both NL and L groups were evaluated on three consecutive days, day one: anthropometric measurements; day two: aerobic capacity and muscle function and day three: lipid profile and glycemic control. Data are presented as mean ± standard deviation (SD) and median plus interquartile range (IQR) according to their assumption of normality. Results: The L group increased the body weight (81.62 ± 22.04 kg vs 74.04 ± 24.46 kg; p = 0.05), body mass index (32.54 ± 5,49 kg/m² vs 30.48 ± 6.88 kg/m²; p = 0.04), body mass index by z-score (3.10 ± 0.60 SD vs 2.67 ± 0.85 SD; p = 0.0015), triglycerides [141.00 mg/dl IQR (106.00-190.00 mg/dl) vs 103.00 mg/dl IQR (78.50- 141.50 mg/dl); p = 0.001], fasting insulin [31.00 mU/L IQR (25.01 - 47-17 mU/L vs 21.82 mU/L IQR (16.88 - 33.10 mU/L; p = 0.001)] and Conclusions: The lockdown due COVID-19 pandemic had a negative impact on the anthropometric measurements, lipid profile, and glycemic control of overweight and obese children and adolescents.

Different criteria for body mass index classification for excess weight screening in children aged six to ten years / Diferentes critérios de classificação do índice de massa corporal para o rastreio do excesso de peso em crianças de seis a dez anos

ABSTRACT Objective: To evaluate the agreement between body mass index (BMI) parameters applied to children aged six to ten years in the city of Montes Claros (MG), Brazil with national and international criteria, also calculating their sensitivity and specificity regarding excess weight screening. Methods: A sample comprising 4151 children aged six to ten years was assessed, with height and body mass determined for BMI calculation. The obtained values were classified according to cutoff points established by the World Health Organization (WHO), International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), Conde & Monteiro, and a recent local proposal. The agreement index between the mentioned criteria was calculated and thereafter the sensitivity and specificity. Results: The local proposal was proven to be highly consistent in most combinations, especially concerning the excess weight criteria of the World Health Organization (WHO) (k=0.895). Regarding excess weight, the local proposal presented sensitivity and specificity values of 0.8680 and 0.9956, respectively, indicating high BMI discrimination power. Conclusions: The locally applied BMI parameters for children aged six to ten years represent a valid, highly viable and practical proposal for excess weight screening in this population group, improving professional decision-making in their follow-up.

Laparoscopic bariatric surgery in adolescents: early and five- year clinical and laboratory assessment / Cirurgia bariátrica videolaparoscópica em adolescentes: avaliação clínica e laboratorial precoce e após cinco anos

ABSTRACT BACKGROUND: Obesity has reached epidemic proportions among adolescents. Methods, such as bariatric surgery, have become the most effective treatment for patients with classes III and IV obesity. AIM: To evaluate weight loss, comorbidity remission, and long-term results of bariatric surgery in adolescents. METHODS: Study with adolescent patients undergoing bariatric surgery, evaluating laboratory tests, comorbidities, and the percentage of excess weight loss in the preoperative period and at one, two, and five years postoperatively. RESULTS: A total of 65 patients who met the inclusion criteria, with a mean age of 18.6 years, were included in the analysis. In the preoperative period, 30.8% of hypercholesterolemia, 23.1% of systemic arterial hypertension, and 18.4% of type 2 diabetes were recorded, with remission of these percentages occurring in 60, 66.7 and 83.4%, respectively. The mean percentage of excess weight loss was 63.48% after one year of surgery, 64.75% after two years, and 57.28% after five years. The mean preoperative total cholesterol level was 180.26 mg/dL, and after one, two, and five years, it was 156.89 mg/dL, 161.39 mg/dL, and 150.97 mg/dL, respectively. The initial mean of low-density lipoprotein was 102.19mg/dL and after five years the mean value reduced to 81.81 mg/dL. The mean preoperative glycemia was 85.08 mg/dL and reduced to 79.13 mg/dL after one year, and to 76.19 mg/dL after five years. CONCLUSIONS: Bariatric surgery is safe and effective in adolescents, with low morbidity, resulting in a loss of excess weight and long-term stability, improving laboratory tests, and leading to remission of comorbidities, such as diabetes mellitus, hypercholesterolemia, and systemic arterial hypertension.

Exploring factors associated with obesity in Argentinian children using structural equation modeling / Explorando factores asociados a la obesidad en niños argentinos usando un modelo de ecuaciones estructurales / Explorando fatores associados à obesidade em crianças argentinas utilizando a modelagem de equações estruturais

Abstract: Habits and behaviors related to obesity risk are strongly associated with the family environment and are affected by socioeconomic factors. Structural equation modeling (SEM) allows us to hypothesize on how the relationships between these factors occur and measure their impact. This study aimed to explore the relationship between family socioeconomic indicators and childhood obesity, mediated by habits linked to energy balance, applying a SEM. A cross sectional study was performed on 861 Argentinian schoolchildren aged 6-12 years, from 2015 to 2016. The model included three latent variables: socioeconomic status, healthy habits, and obesity. Socioeconomic status indicators and healthy habits were surveyed by self-administered parental questionnaires, whereas obesity indicators were evaluated with anthropometry. The applied model showed an acceptable fit (NFI = 0.966; CFI = 0.979; RMSEA = 0.048). Socioeconomic status positively influenced parental education, health insurance, and car possession, while negatively influenced crowding (p < 0.001). Healthy habits significantly influenced physical activity, meals frequency, and sleep hours, while negatively influenced sedentary hours and mother's nutritional status (p < 0.001). Obesity factor positively influenced body mass index, body fat, and waist-to-height ratio (p < 0.001). Finally, socioeconomic status positively influenced health habits, which in turn negatively influenced obesity factor. Healthy habits (especially physical activity and mother's nutritional status) mediated the relationship between socioeconomic status and child obesity. Further research should include other indicators related to diet, eating habits, and physical activity like neighborhood characteristics.

Resumen: Los hábitos y comportamientos relacionados con el riesgo de obesidad están fuertemente asociados al entorno familiar y se ven afectados por factores socioeconómicos. El modelo de ecuaciones estructurales (MEE) permite plantear hipótesis sobre cómo se dan las relaciones entre estos factores y medir su impacto. El objetivo del presente estudio fue explorar la relación entre los indicadores socioeconómicos familiares y la obesidad infantil, mediada por hábitos relacionados con el balance energético, aplicando un MEE. Se realizó un estudio transversal con 861 escolares argentinos de 6 a 12 años entre 2015 y 2016. El modelo incluyó tres variables latentes: nivel socioeconómico, hábitos saludables y obesidad. Los indicadores nivel socioeconómico y hábitos saludables se midieron mediante cuestionarios autoadministrados a los padres, mientras que los indicadores de obesidad se obtuvieron mediante antropometría. El modelo aplicado presentó un ajuste aceptable (NFI = 0,966; CFI = 0,979; RMSEA = 0,048). El nivel socioeconómico influyó positivamente en la escolaridad de los padres, en el plan de salud y en el hecho de tener automóvil, mientras que influyó negativamente en el hacinamiento (p < 0,001). La variable hábitos saludables influyó significativamente en la actividad física, en la frecuencia de las comidas y en las horas de sueño, pero influyó negativamente en las horas sedentarias y en el estado nutricional materno (p < 0,001). El factor obesidad influyó positivamente en el índice de masa corporal, en la grasa corporal y en la razón cintura/talla (p < 0,001). Finalmente, el nivel socioeconómico influyó positivamente en los hábitos saludables, que, a su vez, influyeron negativamente en la obesidad. Los hábitos saludables, en especial la actividad física y el estado nutricional materno, moderan la relación entre el nivel socioeconómico y la obesidad infantil. Las nuevas investigaciones deberían incluir otros indicadores relacionados con la dieta, con los hábitos alimentarios y con la actividad física, así como con las características del vecindario.

Resumo: Hábitos e comportamentos relacionados ao risco de obesidade estão fortemente associados ao ambiente familiar e afetados por fatores socioeconômicos. A modelagem de equações estruturais (MEE) permite levantar hipóteses sobre como ocorrem as relações entre esses fatores e medir seu impacto. O objetivo do presente estudo foi explorar a relação entre os indicadores socioeconômicos familiares e a obesidade infantil, mediada por hábitos ligados ao balanço energético, aplicando uma MEE. Um estudo transversal foi realizado com 861 escolares argentinos de 6 a 12 anos entre 2015 e 2016. O modelo incluiu três variáveis latentes: nível socioeconômico, hábitos saudáveis e obesidade. Os indicadores do nível socioeconômico e de hábitos saudáveis foram medidos por meio de questionários autoaplicáveis aos pais, enquanto os indicadores de obesidade foram obtidos por meio de antropometria. O modelo aplicado apresentou um ajuste aceitável (NFI = 0,966; CFI = 0,979; RMSEA = 0,048). O nível socioeconômico influenciou positivamente a escolaridade dos pais, o plano de saúde e a posse de automóvel, enquanto influenciou negativamente a aglomeração (p < 0,001). A variável hábitso saudáveis influenciou significativamente a atividade física, a frequência das refeições e as horas de sono, mas influenciou negativamente as horas sedentárias e o estado nutricional materno (p < 0,001). O fator obesidade influenciou positivamente o índice de massa corporal, a gordura corporal e a relação cintura/estatura (p < 0,001). Finalmente, o nível socioeconômico influenciou positivamente os hábitso saudáveis, que por sua vez influenciou negativamente a obesidade. Hábitos saudáveis, especialmente atividade física e estado nutricional materno, mediam a relação entre nível socioeconômico e obesidade infantil. Novas pesquisas devem incluir outros indicadores relacionados à dieta, hábitos alimentares e atividade física, como características da vizinhança.

The influence of neighborhood safety and built environment on childhood obesity: isolated and combined effect of contextual factors / A influência da segurança da vizinhança e do ambiente construído sobre a obesidade infantil: efeitos isolado e combinado de fatores contextuais / La influencia de la seguridad del vecindario y el ambiente construido sobre la obesidad infantil: efectos aislados y combinados de los factores contextuales

Abstract: This study aims to analyze the isolated and combined effect of objective measures concerning neighborhood safety, food, and physical activity environments on students' obesity. This is a cross-sectional study conducted with 9- and 10-year-old children enrolled in the municipal education network of a Brazilian metropolis. Environment objective measures comprised neighborhood unsafety (annual criminality and road traffic accident rates), availability of public parks and spaces for physical activity practicing, and index of establishments that predominantly sell ultra-processed food. Euclidean buffers of 1,000m around the children's house were used as eligible geographic units. This study adopted the Principal Component Analysis and Generalized Estimation Equation models. Stratified analyses were conducted based on neighborhood unsafety and on child's family income. In total, 717 students were assessed, 12.2% of them were children with obesity. The latent variable of the obesogenic environment (deduced by environment unsafety rates and the index of establishments that predominantly sell ultra-processed food) was a risk factor for obesity in children with lower socioeconomic levels (OR = 2.37; 95%CI: 1.06-5.19). Public parks and spaces for physical activity practicing were protective factors against childhood obesity only in locations recording the lowest environment unsafety rates (OR = 0.30; 95%CI: 0.09-0.94). Based on our findings, social conditions change the effect of the environment on childhood obesity, reinforcing the relevance of inter-sectoral policies and strategies against this condition.

Resumo: Este artigo busca analisar os efeitos isolado e combinado de medidas objetivas relativas à segurança da vizinhança, alimentação e ambientes de atividade física sobre a obesidade de crianças em idade escolar. Este estudo transversal foi realizado com crianças de 9 e 10 anos de idade que estavam matriculadas na rede municipal de ensino de uma metrópole brasileira. As medidas objetivas ambientais incluíram a insegurança nos bairros (índices anuais de criminalidade e acidentes de trânsito), disponibilidade de logradouros e espaços públicos para a prática de atividade física e o índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados. Um buffer euclidiano de 1.000m em torno da casa das crianças foi tomado como unidade geográfica elegível. Nossa análise englobou os modelos de Análise de Componentes Principais e de Estimação de Equação Generalizada. Análises estratificadas foram realizadas com base na insegurança da vizinhança e na renda familiar da família da criança. Avaliamos 717 estudantes, 12,2% dos quais eram obesos. A variável latente ambiente obesogênico (deduzida das taxas de insegurança ambiental e do índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados) constituiu o fator de risco para obesidade em crianças em famílias de baixa renda (OR = 2,37; IC95%: 1,06-5,19). Parques e espaços públicos para a prática de atividade física foram fatores de proteção contra a obesidade infantil apenas nos locais que registraram as menores taxas de insegurança ambiental (OR = 0,30; IC95%: 0,09-0,94). Com base em nossos achados, a condição social modifica o efeito do ambiente sobre a obesidade infantil e reforça a relevância de políticas e estratégias intersetoriais para prevenir a obesidade infantil.
