Association between breast feeding and food consumption according to the degree of processing in Brazil: a cohort study.

BACKGROUND: The benefits of breast feeding may be associated with better formation of eating habits beyond childhood. This study was designed to verify the association between breast feeding and food consumption according to the degree of processing in four Brazilian birth cohorts. METHODS: The duration of exclusive, predominant and total breast feeding was evaluated. The analysis of the energy contribution of fresh or minimally processed foods (FMPF) and ultra-processed foods (UPF) in the diet was evaluated during childhood (13-36 months), adolescence (11-18 years) and adulthood (22, 23 and 30 years). RESULTS: Those who were predominantly breastfed for less than 4 months had a higher UPF consumption (ß 3.14, 95% CI 0.82 to 5.47) and a lower FMPF consumption (ß -3.47, 95% CI -5.91 to -1.02) at age 22 years in the 1993 cohort. Exclusive breast feeding (EBF) for less than 6 months was associated with increased UPF consumption (ß 1.75, 95% CI 0.25 to 3.24) and reduced FMPF consumption (ß -1.49, 95% CI -2.93 to -0.04) at age 11 years in the 2004 cohort. In this same cohort, total breast feeding for less than 12 months was associated with increased UPF consumption (ß 1.12, 95% CI 0.24 to 2.19) and decreased FMPF consumption (ß -1.13, 95% CI -2 .07 to -0.19). Children who did not receive EBF for 6 months showed an increase in the energy contribution of UPF (ß 2.36, 95% CI 0.53 to 4.18) and a decrease in FMPF (ß -2.33, 95% CI -4 .19 to -0.48) in the diet at 13-36 months in the 2010 cohort. In this cohort, children who were breastfed for less than 12 months in total had higher UPF consumption (ß 2.16, 95% CI 0.81 to 3.51) and lower FMPF consumption (ß -1.79, 95% CI -3.09 to -0.48). CONCLUSION: Exposure to breast feeding is associated with lower UPF consumption and higher FMPF consumption in childhood, adolescence and adulthood.

Complementary feeding indicators from the World Health Organization and the Ministry of Health: agreement analysis and comparison of estimated prevalence in a cohort of children in southwestern Bahia, Brazil, 2018.

OBJECTIVE: To assess the agreement between complementary feeding indicators established by the World Health Organization (WHO) and the Ministry of Health (MOH) and to compare the prevalence of these indicators in the first year of a child's life. METHODS: : This was a cross-sectional study in a cohort of 286 children from Vitória da Conquista, state of Bahia, Brazil; agreement between indicators and comparison between prevalences were analyzed using the Kappa coefficient and McNemar's test; the prevalence of the indicators "introduction of complementary feeding" (ICF), "minimum dietary diversity" (MDD), "minimum meal frequency" (MMF) and "minimum acceptable diet" (MAD) were calculated. RESULTS: : Three indicators showed poor agreement, with only one demonstrating moderate agreement; prevalence of WHO indicators was higher than that of the MOH (ICF, 94.3% vs. 20.7%; MDD, 75.2% vs. 50.7%; MMF, 97.2% vs. 44.8%; MAD, 96.8% vs. 26.9%). CONCLUSION: The majority of indicators showed poor agreement and the prevalence of WHO indicators exceeded that of the Ministry of Health.

Performance of Body Fat Percentage, Fat Mass Index and Body Mass Index for Detecting Cardiometabolic Outcomes in Brazilian Adults.

Obesity is a recognized risk factor for the development of cardiometabolic outcomes. Therefore, it is essential to evaluate anthropometric and body composition indicators used for its diagnosis. This study aimed to assess the diagnostic performance of body fat percentage (BF%), fat mass index (FMI) and body mass index (BMI) for detecting cardiometabolic outcomes in adults. A cross-sectional study was conducted involving adults at 30 years of age from Pelotas, RS (n = 3517) and at 37-39 years from Ribeirão Preto, SP (n = 1696). Receiver operating characteristic (ROC) curves were used to determine the cut-off points for predicting cardiometabolic risk factors, including altered blood pressure, blood glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDDL-c), C-reactive protein and glycated hemoglobin. The cut-off points of BF% ranged from 25.2 to 27.8 in men and from 37.4 to 39.7 in women at 30 years, and from 26.1 to 27.8 in men and from 38.5 to 42.2 in women at 37-39 years. For FMI (kg/m2), the cut-off points ranged from 6.3 to 7.5 in men and from 9.5 to 10.8 in women at 30 years, and from 7.3 to 7.8 in men and from 10.2 to 12.2 in women at 37-39 years. The BMI cut-off points (kg/m2) ranged from 26.3 to 27.3 in men and from 25.4 to 27.2 in women at 30 years, and from 28.3 to 29.0 in men and from 27.2 to 29.6 in women at 37-39 years. The areas under the curve were similar for the three indicators, ranging from 0.523 to 0.746. BMI showed a performance similar to that of the body fat-based indicators in identifying cardiometabolic outcomes. The cut-off points of the three indicators showed acceptable discriminatory power in subjects with cardiometabolic risk factors.

Association between the Consumption of Ultra-Processed Foods and Asthma in Adults from Ribeirão Preto, São Paulo, Brazil.

BACKGROUND: Ultra-processed Food (UPF) consumption can play a role in the pathogenesis and progression of asthma. The aim of this study was to evaluate the association between the consumption of UPF and asthma. METHODS: This cross-sectional study included 1857 adults aged 23-25 years from the Ribeirão Preto-SP birth cohort (1978/1979). The exposure variable was the consumption of UPF (expressed as their percentage contribution to energy intake-% total caloric value [%TCV] and their percentage contribution to the amount of food ingested-%grams), which was assessed with a food frequency questionnaire. Asthma was the outcome and was defined based on a positive methacholine challenge test and the presence of wheezing, chest tightness, or shortness of breath over the last 12 months. Poisson regression with robust variance was used to estimate the association between these variables. Unadjusted analyses and analyses adjusted for sex, age, household income, smoking, and physical activity level were performed. RESULTS: The prevalence of asthma in the sample was 13.2%. The mean total consumption of UPF was 37.9 ± 11.2% TCV (corresponding to 35.1 ± 15.1% grams). There was no association between the consumption of UPF and asthma in adults. CONCLUSION: This study provides no evidence for an association between the consumption of UPF and asthma in young adults.

Impact of omega-3 supplementation on children and adolescents patients with cystic fibrosis: A systematic review and meta-analysis of randomized-controlled trials.

OBJECTIVE: Clinical trial research have provided evidence that omega-3 may have larger potential benefits for treating cystic fibrosis (CF). This study's objective was to assess the impact of three supplementation on pediatric CF patients. METHODS: Scopus, PubMed/Medline, Web of Science, Cochrane, and Embase databases were searched from commencement until July 20, 2022 using standard keywords to identify all randomized controlled studies (RCTs) examining the effects of omega-3 supplementation on young patients with CF. The eligible studies were subjected to a random-effects model meta-analysis. RESULTS: A meta-analysis of 12 the eligible studies was performed. Findings of the study showed that omega-3 supplementation significantly increased the levels of docosahexaenoic acid (weighted mean [WMD]: 2.06%, 95% confidence interval [CI]: 1.29, 2.82, p < 0.001) and eicosapentaenoic acid (WMD: 0.32%, 95% CI: 0.15, 0.48, p < 0.001) as well as decreased arachidonic acid (WMD: -0.78%, 95% CI: -1.50, -0.05, p = 0.035) and C-receptive protein (CRP) (WMD: -3.76 mg/L, 95% CI: -7.42, -0.10, p = 0.044) especially when used in higher doses and for a longer period of time compared to the control group. However, no significant effect was observed on other factors including forced expiratory volume 1, forced vital capacity as well as anthropometric parameters. In addition, high heterogeneity was reported for all fatty acids, but heterogeneity was low and nonsignificant for other variables. CONCLUSION: The finding showed that in pediatric patients with CF, omega-3 supplementation showed benefits only in plasma fatty acid profile and serum CRP.

Maternal smoking during pregnancy and birthweight on the third generation: results from two birth cohort studies.

The purpose of this research is to investigate whether grandmother's smoking during pregnancy reduces the grandchildren's birthweight and whether maternal smoking during pregnancy modified this association. We also evaluated the effect of duration and intensity of smoking. This study included data from three generations from two birth cohorts carried out in Pelotas, a southern Brazilian city: women enrolled in the perinatal study in the 1982 and 1993 cohorts (G1); daughters (G2) of those G1 mothers who were followed to adulthood; and first children (G3) born from G2 women. Information on maternal smoking during pregnancy was obtained from women (G1) shortly after delivery of the two cohorts and from G2 in the follow-up in adulthood of the 1993 cohort. Mothers (G2) reported G3 birthweight during the follow-up visit at adulthood. Multiple linear regression was used to obtain effect measures adjusted for confounders. The study included 1602 grandmothers (G1), mothers (G2), and grandchildren (G3). Prevalence of maternal (G1) smoking during pregnancy was 43% and mean G3 birthweight was 3118.9 g (SD: 608.8). Grandmother's smoking in the pregnancy was not associated with grandchild's birthweight. However, offspring of both G1 and G2 smokers had lower mean birthweight than those whose mother and grandmother did not smoke (adjusted ß: - 223.05; 95% CI: - 415.16, - 32.76). CONCLUSION: No significant association was observed between grandmother's smoking in the pregnancy and grandchild's birthweight. But it seems that grandmother's smoking in pregnancy has an effect on grandchild's birthweight when the mother also smoked in the pregnancy. . WHAT IS KNOWN: • Most studies on the association of maternal tobacco smoking in pregnancy with offspring birthweight have been restricted to two generations, and an inverse association is well known. WHAT IS NEW: • Besides to investigate whether grandmother's smoking during pregnancy reduces the grandchildren's birthweight, we examined whether this association varied according to maternal smoking during pregnancy.

Associations of the Paleolithic Diet Pattern Scores and the Risk of Breast Cancer among Adults: A Case-Control Study.

Evidence suggests the role of changing traditional lifestyle patterns such as Paleolithic to modern lifestyle in the incidence and epidemic of chronic diseases. Thus, this study aimed to investigate the association between Paleolithic diet (PD) and risk of Breast Cancer (BC) in adult Iranian women. This matched case-control study included 253 women with BC and 267 healthy women aged >18 years. PD score was evaluated using a validated 168-item quantitative food frequency questionnaire. Conditional logistic regression model was used to estimate odds ratios (ORs) and 95% confidence intervals (95%CIs), and dose-response was investigated. Mean of PD score was 39.00 ± 6.39. Among the food groups of the PD components, BC patients significantly had lower consumption of healthy food groups as vegetables, fruits, fish, and nuts, higher intakes of sugar-sweetened beverages as well as grains and starches. After adjustment for potential confounders, comparing the highest quartile of PD scores with the lowest quartile, a decrease in the risk of BC was observed for all women (OR: 0.26; 95% CI: 0.13-0.53), as well as those premenopausal (OR: 0.29; 95% CI: 0.11), and postmenopausal (OR: 0.17; 95% CI: 0.05 - 0.56). Our findings show that adherence to the PD pattern significantly reduces the risk of BC in the population studied. However, prospective studies are needed to further investigate this association.

Food profile of Yanomami indigenous children aged 6 to 59 months from the Brazilian Amazon, according to the degree of food processing: a cross-sectional study.

OBJECTIVE: The current study aimed to characterise the food profile of Yanomami indigenous children according to the degree of food processing and its associated factors. DESIGN: This is a cross-sectional study with Yanomami indigenous children aged 6 to 59 months. Socio-demographic, maternal and infant data were collected through a standardised questionnaire. The food profile was obtained by using a list of thirty-four foods to verify the child's consumption of these foods on the day preceding the interview. Foods were classified according to the degree of processing based on the NOVA system (in natura or minimally processed, processed culinary ingredients, processed and ultra-processed). In natura and minimally processed foods were subdivided into 'regional' and 'urban' foods. Poisson regression analysis was applied to estimate the associated factors according to the 90 % CI. SETTING: Three villages (Auaris, Maturacá and Ariabú) in the Yanomami indigenous territory, in the Brazilian Amazon. PARTICIPANTS: In total, 251 Yanomami children aged 6 to 59 months were evaluated. RESULTS: The prevalence of consumption of 'regional' and 'urban' in natura or minimally processed foods was 93 % and 56 %, respectively, and consumption of ultra-processed foods was 32 %. Ultra-processed food consumption was 11·6 times higher in children of Maturacá and 9·2 times higher in Ariabú when compared with the children of Auaris and 31 % lower in children who had mothers with shorter stature. CONCLUSION: Despite the high frequency of consumption of in natura and minimally processed foods, the consumption of ultra-processed foods was substantial and was associated with demographic and maternal factors in Yanomani indigenous children under 5 years of age.

Mouthwash use and oral cancer: a systematic review and meta-analysis

ABSTRACT OBJECTIVE This study aimed to investigate the effect of mouthwash use on the development of oral cancer. METHODS Observational studies with adult/older adult populations that have examined the association between mouthwash use and oral cancer were included. Electronic search was performed in July 2022, with no time or language restrictions. PubMed/Medline, Embase, and Web of Science databases were used, and the search was extended to theses and dissertations libraries, Google Scholar, reference lists, and other sources. Methodological quality was assessed using the Newcastle-Ottawa Scale and quantitative data synthesis was performed by random effects meta-analysis, with different subgroup analyses and meta-regression. This revision was registered in Prospero (CRD42020143307). RESULTS Of the 4,094 studies identified in the search, 15 case-control studies were included in the review, totaling 6,515 cases and 17,037 controls. The meta-analysis included 17 measures of effect from 15 case-control studies. The pooled OR was 1.00 (95%CI: 0.79-1.26, n = 17 studies), but it was 2.58 (95%CI: 1.38-4.82, n = 2 studies) among those who had used mouthwashes three times or more times a day, and 1.30 (95%CI: 1.10-1.54, n = 4 studies) among those who had used mouthwashes for more than 40 years. CONCLUSIONS We found evidence that a high frequency of mouthwash use may be associated with an increased risk of oral cancer. However, despite the biological plausibility for this association, we suggest caution upon interpretation of our findings due to the few number of studies that have investigated the mouthwash use frequency, which should be considered. Therefore, we recommend that future studies assess, in detail, the frequency, duration, and content of mouthwashes to increase the strength of evidence for a possible dose-response effect of mouthwashes on oral cancer risk.

Prevalence and determinants of complementary feeding indicators in the first year of life in the Southwest of Bahia State / Prevalência e determinantes de indicadores da alimentação complementar no primeiro ano de vida no Sudoeste baiano

Abstract Objectives: to estimate the prevalence of complementary feeding indicators and investigate its determinants. Methods: cross-sectional study with 12-month-old children from Vitória da Conquista, Bahia. The indicators minimum diet diversity, minimum meal frequency and minimally acceptable diet were constructed and adapted to the current recommendations of the food guide for Brazilian children under two years of age. Poisson regression analysis was used, with hierarchical entry of variables in the multivariate model. Results: the prevalence of minimum diet diversity was 38.8%, minimum meal frequency 47.9% and minimally acceptable diet 18.5%. Family income greater than one minimum wage was associated with minimal diet diversity (PR= 1.49; CI95%= 1.39-2.26); receiving guidance on complementary feeding was associated with a minimum meal frequency (PR= 1.37; CI95%= 1.05-1.78); and children who received exclusive breastfeeding for up to 6 months had significantly higher prevalences of all indicators compared to those who did not. Conclusions: low prevalence of complementary feeding indicators was observed. The variables family income, receiving guidance on complementary feeding and offering exclusive breastfeeding for six months were associated with the highest prevalence of the studied indicators.

Resumo Objetivos: estimar as prevalências de indicadores da alimentação complementar e investigar seus determinantes. Métodos: estudo transversal com crianças aos 12 meses de idade do município de Vitória da Conquista, Bahia. Os indicadores diversidade mínima da dieta, frequência mínima de refeição e dieta minimamente aceitável foram construídos e adaptados às atuais recomendações do Guia alimentar para crianças brasileiras menores de dois anos. Utilizou-se análise de regressão de Poisson, com entrada hierarquizada das variáveis no modelo multivariado. Resultados: a prevalência de diversidade mínima da dieta foi de 38,8%, de frequência mínima de refeição 47,9% e de dieta minimamente aceitável 18,5%. A renda familiar maior que um saláriomínimo foi associada a diversidade mínima da dieta (RP= 1,49; IC95%= 1,39-2,26); o recebimento de orientações sobre alimentação complementar associou-se a frequência mínima de refeição (RP=1,37; IC95%= 1,05-1,78); e as crianças que receberam aleitamento materno exclusivo até 6 meses apresentaram prevalências significativamente maiores de todos os indicadores comparadas às que não receberam. Conclusões: foram observadas baixas prevalências dos indicadores da alimentação complementar. As variáveis renda familiar, recebimento de orientações sobre alimentação complementar e a oferta de aleitamento materno exclusivo por seis meses foram associadas as maiores prevalências dos indicadores estudados.

Ultra-processed food consumption is associated with increase in fat mass and decrease in lean mass in Brazilian women: A cohort study.

Objective: To investigate the association between ultra-processed food consumption at 23-25 years of age and measurements of body composition-fat mass, fat mass distribution and lean mass at 37-39 years of age in Brazilian adults. Methods: 1978/1979 birth cohort study conducted with healthy adults from Ribeirão Preto, São Paulo, Brazil. A total of 1,021 individuals participated in the fat mass analysis (measured by air displacement plethysmography) and 815 in the lean mass analysis and fat mass distribution (assessed by dual energy X-ray absorptiometry). Food consumption was evaluated by a food frequency questionnaire. Food items were grouped according to the level of processing as per the NOVA classification. Ultra-processed food consumption was expressed as a percentage of total daily intake (g/day). Linear regression models were used to estimate the effect of ultra-processed food consumption (g/day) on body mass index, body fat percentage, fat mass index, android fat, gynoid fat, android-gynoid fat ratio, lean mass percentage, lean mass index and appendicular lean mass index. Marginal plots were produced to visualize interactions. Results: The mean daily ultra-processed food consumption in grams was 35.8% (813.3 g). There was an association between ultra-processed food consumption and increase in body mass index, body fat percentage, fat mass index, android fat and gynoid fat and decrease in lean mass percentage, only in women. Conclusion: A high ultra-processed food consumption is associated with a long-term increase in fat mass and a decrease in lean mass in adult women.

Sex-Dependent Effects of the Intake of NOVA Classified Ultra-Processed Foods on Syndrome Metabolic Components in Brazilian Adults.

Longitudinal studies evaluating the relationship between UPF consumption and the incidence of Metabolic Syndrome (MetS) and its components are still scarce. This study aimed to evaluate the effect of UPF consumption on the incidence of MetS and its components in adults. A prospective study was conducted with 896 participants from the 1978/79 Ribeirão Preto cohort, São Paulo, Brazil. UPF consumption was evaluated in %kcal and %g at ages 23-25 years. Incidence of MetS and its components were estimated at ages 37-39 years, according to the Joint Interim Statement criteria. Poisson regression was used to assess associations, and interactions with sex were investigated. UPF consumption had no association with MetS (%kcal Adjusted PR: 1.00; 95% CI: 0.99-1.01; %g Adjusted PR: 1.00; 95% CI: 0.99-1.01). However, women with higher UPF consumption, in %kcal and %g, had a higher risk of abdominal obesity (%kcal: p = 0.030; %g: p = 0.003); and women with higher UPF consumption, in %g, had a higher risk of low HDL-cholesterol (p = 0.041). For the other components of MetS, no significant associations were observed in either sex. These findings suggest evidence of no association between UPF consumption and MetS; however, consumption of UPF was associated with increased WC and low HDL-c, but only in women.

Prevalence of self-medication and associated factors in adolescents aged 18-19 years: the 1997/1998 cohort in São Luís-MA, Brazil / Prevalência de automedicação e fatores associados em adolescentes de 18-19 anos: a coorte de 1997/1998 em São Luís-MA, Brasil

Abstract This article aims to assess the prevalence and factors associated with self-medication in adolescents. Cross-sectional study, nested in cohort, with 2,515 adolescents aged 18-19 years born in São Luís-MA. The use of medication in the last 15 days without a medical prescription or by a qualified professional was considered self-medication. Factors associated with self-medication were evaluated using Poisson regression with robust variances and hierarchical selection of variables. Medicines were used in the last 15 days by 48.05% of adolescents. Among these, 70.09% use it without a prescription or indication from another health professional. The most used medications for self-medication were "over the counter" (93.68%). Self-medication was positively associated with female gender (PR: 1.41; 95%CI: 1.25-1.59), screen time ≥5h/day (PR: 1.32; 95%CI: 1.05-1.67) and self-reported diagnosis of allergic rhinitis (PR: 1.19; 95%CI: 1.02-1.39); however, negatively associated with self-satisfaction with health (PR: 0.79; 95%CI: 0.67-0.94) and hospitalization in the previous year (PR: 0.70; 95%CI: 0.50-0.97). Self-medication was common among adolescents and to reduce this practice, greater attention should be given to women, individuals with intense exposure to meshes and allergic diseases.

Resumo O objetivo deste artigo é avaliar a prevalência e os fatores associados a automedicação em adolescentes. Estudo transversal, aninhado a uma coorte, com 2.515 adolescentes de 18-19 anos nascidos em São Luís-MA. O uso de algum medicamento nos últimos 15 dias sem prescrição médica ou de profissional habilitado foi considerado automedicação. Os fatores associados a automedicação foram avaliados usando regressão de Poisson com variâncias robustas e seleção hierárquica das variáveis. Medicamentos foram utilizados nos últimos 15 dias por 48,05% dos adolescentes. Entre estes, 70,09% fazem uso sem receita médica ou indicação de outro profissional de saúde. Os medicamentos mais utilizados na automedicação foram os "over the counter" (93,68%). A automedicação foi positivamente associada ao sexo feminino (RP: 1,41; IC95%: 1,25-1,59), tempo de tela ≥5h/dia (RP: 1,32; IC95%: 1,05-1,67) e diagnóstico autorreferido de rinite alérgica (RP: 1,19; IC95%: 1,02-1,39); porém, negativamente associada a autossatisfação com a saúde (PR: 0,79; IC95%: 0,67-0,94) e hospitalização no ano anterior (RP: 0,70; IC95%: 0,50-0,97). A automedicação foi comum entre os adolescentes e para redução dessa prática uma maior atenção deve ser dada a mulheres, indivíduos com intensa exposição a telas e doenças alérgicas.

Agreement of adolescents' self-perception of their body image with the analysis on the three-dimensional body image / Concordância da autopercepção da imagem corporal com a análise de imagem corporal tridimensional de adolescentes

Abstract Objectives: to verify the agreement among adolescents' perception of their own body image and the health professionals' analysis based on three-dimensional body image and the inter-rater agreement. Methods: a cross-sectional study was carried out with 1,662 adolescents, aged 18 to 19 years old, from the 1997/98 birth cohort in São Luís, Maranhão. Self-perception of body image was assessed using the Stunkard's body image scale. Three nutritionists evaluated the three-dimensional body image obtained by the Photonic Scanner (3D Body Scanner) and classified according to the Stunkard's scale. The agreement between raters was verified by using weighted Kappa. Results: the analysis of agreement between raters in the general group and when stratified by sexwas considered moderate to good by Kappa. Regarding the intraclass correlation (ICC), good and excellent correlation values were observed both in the general group, males and females. There was a greater perception of overweight by all raters, when compared with the adolescents' self-assessments. When stratified by sex, examiner 1 had the same perception as male self-assessments, as for females the perception of overweight was more frequent, as well as raters 2 and 3, for both sexes. Conclusion: agreement between raters and self-assessments was considered weak/moderate in Kappa and good/excellent in ICC.

Resumo Objetivos: verificar a concordância da autopercepção da imagem corporal de adolescentes com a análise de profissionais da saúde a partir de imagem corporal tridimensional e a concordância inter-avaliadores. Métodos: estudo transversal, com 1662 adolescentes, de 18-19 anos, da coorte de nascimento de 1997/98 de São Luís, Maranhão. A autopercepção da imagem corporal foi avaliada pela escala de imagem corporal de Stunkard. Três nutricionistas avaliaram a imagem corporal tridimensional e classificaram conforme Stunkard. A concordância foi verificada utilizando Kappa ponderado. Resultados: a análise de concordância entre os avaliadores no grupo geral e quando estratificada por sexo foi considerada moderada a boa pelo Kappa. Em relação a correlação intraclasse (ICC), observou-se valores de correlação bons e excelentes tanto no grupo geral, quanto no sexo masculino e no feminino. Notou-se maior percepção de excesso de peso por todos os avaliadores, quando comparado às autoavaliações dos adolescentes. Quando estratificado por sexo, o avaliador 1 teve a mesma percepção que as autoavaliações do sexo masculino, enquanto para o sexo feminino a percepção de excesso de peso foi mais frequente, assim como os avaliadores 2 e 3, para ambos os sexos. Conclusão: a concordância entre avaliadores e as autoavaliações foram consideradas fracas/moderadas no Kappa e bons/excelente pela ICC.

Trends in insulin-like growth factor-1 levels after bariatric surgery: a systematic review and meta-analysis.

According to studies, there are many inconsistencies in how IGF-1 levels change after bariatric surgery compared to before surgery, as well as its effects. These discrepancies can be attributed to various factors such as age, body mass index (BMI), and duration of intervention. Therefore, the aim of this study was to evaluate the level of insulin-like growth factor-1 (IGF-1) after bariatric surgery. A systematic review and meta-analysis based on the PRISMA guidelines was conducted from inception until 2021. From 1871 articles initially selected, 24 studies with 28 treatment arms met the eligible criteria and were included. Pooled findings from the random-effects model indicated that IGF-1 levels increased significantly [weighted mean difference (WMD) = 8.84 ng/ml; 95% confidence interval (CI) 0.30-17.39; p = 0.043] after bariatric surgery compared to before surgery. No significant heterogeneity was noted among the studies (Cochran Q test, p = 0.90, I2 = 0.0%). In subgroup analysis, bariatric surgery significantly increased IGF-1 levels at age <40 years but not at age ≤40 years. Bariatric surgery is capable of increasing the IGF-1 levels compared to the period prior to surgery but with a modest clinical magnitude.

Excess weight and obesity prevalence in the RPS Brazilian Birth Cohort Consortium (Ribeirão Preto, Pelotas and São Luís).

Our objective was to estimate the prevalence of excess weight and obesity, according to sex and income in the RPS Brazilian Birth Cohort Consortium (Ribeirão Preto, Pelotas, and São Luís). Participants in the Ribeirão Preto (1978/1979 and 1994), Pelotas (1982, 1993 and 2004) and São Luís (1997/1998) birth cohorts were included in different follow-ups from 7 years old onwards. Excess weight (overweight and obesity) were assessed by body mass index. The highest prevalences were observed in Ribeirão Preto (excess weight: 27.7% at 9-11 and 47.1% at 22-23 years; obesity: 8.6% at 9-11 and 19.8% at 22-23 years) while the smallest was in São Luís (excess weight: 5.4 to 7-9 and 17.2% at 18-19 years; obesity: 1.8% at 7-9 and 3.6% at 18-19 years). The younger the cohort, the greater the prevalence of excess weight and obesity when comparing similar age groups. Increases in obesity prevalence were greater than in excess weight prevalence. Women had lower excess weight prevalence in older cohorts and higher obesity prevalence in younger cohorts. Higher excess weight and obesity prevalence were observed in higher income children and adolescents, and in poorer adults. Differences in the prevalence of excess weight and obesity evidenced that individuals from younger cohorts are more exposed to this morbidity, as well as those who were born in the most developed city, low-income adults as well as children and adolescents belonging to families of the highest income tertile. Therefore, the results of this study indicate the need to prioritize actions aimed at younger individuals.

O estudo teve como objetivo estimar as prevalências de excesso de peso e de obesidade, de acordo com sexo e renda, no Consórcio RPS (Ribeirão Preto, Pelotas e São Luís) de coorte de nascimentos brasileiros. Os participantes nas coortes de Ribeirão Preto (1978/1979 e 1994), Pelotas (1982, 1993 e 2004) e São Luís (1997/1998) foram incluídos em diferentes seguimentos a partir dos sete anos de idade. O excesso de peso (sobrepeso e obesidade) e a obesidade foram avaliados pelo índice de massa corporal. As maiores prevalências foram observadas em Ribeirão Preto (excesso de peso: 27,7% aos 9-11 e 47,1% aos 22-23 anos; obesidade: 8,6% aos 9-11 e 19,8% aos 22-23 anos) e as menores taxas em São Luís (excesso de peso: 5,4% aos 7-9 e 17,2% aos 18-19 anos; obesidade: 1,8% aos 7-9 e 3,6% aos 18-19 anos). Quanto mais jovem a coorte, maior a prevalência de excesso de peso e de obesidade, na comparação entre grupos etários semelhantes. O aumento na prevalência de obesidade foi maior que na prevalência de excesso de peso. As mulheres tiveram menor prevalência de excesso de peso nas coortes mais velhas e maior prevalência de obesidade nas coortes mais jovens. Maiores prevalências de excesso de peso e de obesidade foram observadas nas crianças e adolescentes com renda familiar mais alta e em adultos de renda mais baixa. As diferenças nas prevalências de excesso de peso e de obesidade evidenciaram que os indivíduos das coortes mais jovens estão mais expostos a essa morbidade, assim como, aqueles nascidos na cidade mais desenvolvida, os adultos de baixa renda e crianças e adolescentes pertencentes a família do tercil de maior renda. Portanto, os resultados indicam a necessidade de priorizar medidas dirigidas aos indivíduos mais jovens.

El objetivo de este estudio fue estimar la prevalencia de sobrepeso y obesidad, según sexo e ingresos en el Consorcio RPS (Ribeirão Preto, Pelotas and São Luís) cohortes brasileñas de nascimientos. Los participantes en las cohortes de nacimiento de Ribeirão Preto (1978/1979 y 1994), Pelotas (1982, 1993 y 2004) y São Luís (1997/1998) fueron incluidos en diferentes seguimientos desde los 7 años de edad. El exceso de peso (sobrepeso y obesidad) fueron evaluados por el índice de masa corporal. Las prevalencias más altas se observaron en Ribeirão Preto (exceso de peso: 27,7% a los 9-11 y 47,1% a los 22-23 años; obesidad: 8,6% a los 9-11 y 19,8% a los 22-23 años) y los más pequeños en São Luís (exceso de peso: 5,4 a los 7-9 y 17,2% a los 18-19 años; obesidad: 1,8% a los 7-9 y 3,6% a los 18-19 años). Cuanto más joven fuera la cohorte, mayor era la prevalencia de exceso de peso y obesidad, cuando se comparan con grupos de edad similares. El incremento en la prevalencia de obesidad fue mayor que en la prevalencia de exceso de peso. Las mujeres tenían una prevalencia de exceso de peso más baja en las cohortes más viejas y una mayor prevalencia de obesidad en las cohortes más jóvenes. Se observaron prevalencias más altas de exceso de peso y obesidad en los niños y adolescentes con mayores ingresos, y en los adultos más pobres. Las diferencias en las prevalencias de exceso de peso y obesidad evidenciaron que las personas de las cohortes más jóvenes estaban más expuestas a esta morbilidad, al igual que aquellas que habían nacido en las ciudades más desarrolladas, adultos con bajos ingresos, además de niños y adolescentes pertenecientes a las familias del tercil de ingresos más altos. Por eso, los resultados de este estudio indican la necesidad de priorizar acciones dirigidas a las personas más jóvenes.
