There is an association between the AA genotype of rs9939609 polymorphism and BMI among schoolchildren. The association between overweight/obesity in schoolchildren with a family history of obesity was found mainly among students with the AA genotype.
Overweight and obesity are associated with chronic and subclinical inflammation due to an imbalance of inflammatory mediators. However, the association with gene polymorphism has been rarely studied in children. The aim of this study was to determine if serum concentrations of C-reactive protein (CRP) and interleukin-6 (IL-6) are related to the IL6 rs1800795, IL6 rs2069845 and CRP rs1205 polymorphisms (SNPs) according to body mass index (BMI) in a sample of children and adolescents. A cross-sectional study in 470 students between 7 and 17yearsof age of anthropometric characteristics, high sensitivity-CRP (Hs-CRP) and IL-6 levels and three SNPs genotyped. The prevalence ratio of hs-CRP>3mg/L in obese individuals was 4.15 (CI 2.43-7.06; p=0.01), and it was 1.91 (CI 1.03-3.55; p=0.03) in overweight individuals and 1.74 (CI 1.05-2.88 p=0.03) in females. Individuals with waist circumference (WC) and body fat percentage (BF%) alterations showed elevated levels of hs-CRP (p=4.3×10 and p=5.3×10). The combination of any two anthropometric measurement increases CRP levels, especially combinations with obesity body mass index (BMI): BMI+WC and BMI+BF%. Among the overweight/obesity group, T allele carriers of CRP rs1205 showed lower levels of hs-CRP (0.5, IQR=0.3-1.8mg/L) than CC homozygotes (1.5, IQR=0.4-3.4mg/L, p=0.018). Additionally, considering subjects with two or three anthropometric alterations for CRP rs1205: rs1205 T allele carriers had lower levels of hs-CRP (0.7, IQR=0.3-2.7mg/L) than CC homozygotes (1.2, IQR=0.5-3.5mg/L, p=0.02). In conclusion, carriers of the rs1205/T allele with higher BMIs had lower levels of hs-CRP. Schoolchildren who were overweight/obese had higher levels of CRP and IL-6, whereas individuals with WC and BF% alterations had higher levels of CRP.
This study demonstrated that the rs9939609 (FTO) polymorphism showed a relationship with obesity in the population studied and an interaction with CRF. Students with low levels of CRF and the AA genotype have a higher risk of being overweight/obese. This association was not found in students with higher levels of CRF. Am. J. Hum.

Studies focused on the mechanisms involved in the development of obesity in children and adolescents have reported associations between this condition and birth weight, sedentary lifestyle, and hereditary conditions. However, few studies have simultaneously evaluated these factors. This cross-sectional study aims to identify demographic, behavioral, and biological factors associated with overweight/obesity in children and adolescents. 381 schoolchildren aged seven to 17 years were included in the study to evaluate the associations between overweight/obesity and biological factors (including family history of obesity, birth weight, and the fat mass and obesity-associated (FTO) rs9939609 polymorphism), demographic variables (including gender and age), and behavioral variables (including physical activity and/or sports participation). The results of this study showed that there was a lower prevalence of obesity in schoolchildren aged 11–17 years (PR: 0.89; p=0.004). Obesity was more prevalent in children whose father (PR: 1.24; p < 0.001) and maternal grandmother (PR: 1.16; p=0.019) were obese. Higher prevalence rates of obesity were also identified in schoolchildren who were overweight at birth (PR: 1.18; p=0.002) and carriers of the obesity risk genotype (PR: 1.13; p=0.016). Biological factors, such as family history of obesity, overweight at birth, and the presence of the fat mass and obesity-associated rs9939609 polymorphism were associated with the prevalence of obesity in children and adolescents.
RESUMOJustificativa e objetivos: a grande variedade de medicamentos disponíveis no mercado, trouxe importantes mudanças no aspecto de utilização de medicamentos, porém, surgem também, problemas relacionados com estes produtos, dentre estes, a intoxicação exógena, considerada um problema mundial no âmbito da saúde, principalmente entre mulheres. O objetivo do estudo foi analisar os dados notificados por intoxicação exógena por medicamentos entre adultos jovens do Rio Grande do Sul. Métodos: trata-se de um estudo descritivo ecológico sobre os casos de intoxicação exógena por medicamentos de indivíduos entre 20 e 39 anos de idade, do Rio Grande do Sul, notificados nos anos de 2011 a 2015, no Sistema de Informação de Agravos de Notificação (SINAN). Resultados: foram encontradas 1.278 notificações de intoxicações exógenas ocasionadas por medicamentos. Destas, 76,29% eram do sexo feminino, 85,21% eram brancos, 25,98% tinham o ensino fundamental incompleto e 85,52% residiam na zona urbana. Do total de casos notificados, destacam-se os 1.038 casos de tentativa de suicídio (81,28%), seguidos dos 68 casos por automedicação (5,32%). Conclusões: a intoxicação exógena por medicamentos entre adultos jovens no Rio Grande do Sul é grave e preocupante, apontando a importância de medidas educativas de prevenção e promoção da saúde nessa população. DESCRITORES: Medicamentos. Intoxicação. Adulto jovem. ABSTRACT Background and objective: the wide variety of drugs available in the market, brought important changes in the aspect of drug use, however, there are also problems related to these products, among these, exogenous intoxication, considered a world wide problem in the health sector, especially among women. The aim of the study was to analyze the data reported by exogenous drug intoxication among young adults of Rio Grande do Sul. Methods: it is an ecological descriptive study of cases of exogenous drug intoxication of individuals between 20-39 years of age, from Rio Grande do Sul, reported in the years 2011-2015, at Information System for Notifiable Diseases (SINAN). Results: 1,278 notifications of exogenous intoxication caused by drugs were found. Of these, 76.29% of the cases were female, 85.21% were white, 25.98% had incomplete primary education and 85.52% lived in urban areas. Of the reported cases, it highlights the 1,038 cases of attempted suicide (81.22%), followed by 68 cases of self-medication (5.32%). Conclusions: the exogenous drug intoxication among young adults
