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 / Indicadores de alimentación complementaria de la Organización Mundial de la Salud y del Ministerio de Salud: análisis de concordancia y comparación de prevalencias estimadas en una cohorte de niños del suroeste de Bahía, Brasil, 2018 / Indicadores de alimentação complementar da Organização Mundial da Saúde e do Ministério da Saúde: análise de concordância e comparação das prevalências estimadas em uma coorte de crianças no sudoeste da Bahia, 2018

ABSTRACT 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.

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.

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.

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) / Prevalências de excesso de peso e obesidade no Consórcio RPS (Ribeirão Preto, Pelotas e São Luís) de coortes de nascimentos brasileiras, Brasil / Prevalencias de sobrepeso y obesidad en el Consorcio RPS (Ribeirão Preto, Pelotas y São Luís) cohortes brasileñas de nascimientos

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.

Sintomas de ansiedade gestacional e pós-parto e intenção de amamentar exclusivo até os seis meses: resultados de uma coorte prospectiva do Rio de Janeiro / Symptoms of gestational and postpartum anxiety and intention to breastfeed exclusively until six months: results of a prospective cohort in Rio de Janeiro

Objetivo: Avaliar a associação entre sintomas de ansiedade gestacional e pós-parto e intenção de amamentar exclusivamente até os seis meses. Métodos Coorte prospectiva com uma população de mulheres atendidas no serviço de obstetrícia de um centro de saúde do município do Rio de Janeiro. Os sintomas de ansiedade foram avaliados pelo Inventário de Ansiedade Traço/Estado no primeiro trimestre da gestação (ansiedade-traço) e 30-45 dias pós-parto (ansiedade-estado). A intenção de amamentar exclusivamente até seis meses foi avaliada por questionário aplicado 30-45 dias pós-parto. Variáveis independentes foram obtidas de questionários padronizados com dados socioeconômicos, obstétricos e nutricionais. As associações brutas e ajustadas foram testadas por regressão de Poisson com variâncias robustas. Resultados: Foram avaliadas 195 mulheres no primeiro trimestre gestacional e 185 no pós-parto. A prevalência de sintomas de ansiedade-traço ao início da gestação foi de 53%, e ansiedade-estado no pós-parto 29%. Cinquenta e nove por cento das mulheres pretendiam amamentar exclusivamente até seis meses. Nas análises ajustadas, a presença de sintomas de ansiedade-traço associou-se com a intenção de não amamentar exclusivamente até os seis meses (RP=1,70; IC95%=1,07­2,72). A presença de sintomas de ansiedade-estado no pós-parto perdeu a associação com o desfecho após os ajustes (RP=1,54; IC95%=0,97­2,44). Conclusões: A presença de sintomas de ansiedade-traço influencia negativamente na intenção de amamentar exclusivamente até os seis meses. Ressalta-se a importância de avaliar a saúde mental da mulher na gestação e pós-parto visando proteger a manutenção do aleitamento materno exclusivo. (AU)

Objective: To evaluate association between symptoms of gestational and postpartum anxiety and intention to breastfeed exclusively until six months of age. Methods: This was a prospective cohort study with a population of women treated at the obstetrics service of a health center in the municipality of Rio de Janeiro. Anxiety symptoms were assessed by the State-Trait Anxiety Inventory in the first trimester of pregnancy (trait anxiety) and 30-45 days postpartum (state anxiety). Intention to breastfeed exclusively up to six months was assessed by a questionnaire administered 30-45 days postpartum. Independent variables were obtained from standardized questionnaires with socioeconomic, obstetric and nutritional data. Crude and adjusted associations were tested by Poisson regression with robust variance. Results: A total of 195 women were evaluated in the first trimester of pregnancy, and 185 were evaluated in the postpartum period. Prevalence of trait anxiety symptoms at the beginning of pregnancy was 53%, while postpartum state anxiety was 29%. Fifty-nine percent of women intended to breastfeed exclusively for up to six months. In the adjusted analyses, presence of trait anxiety symptoms was associated with the intention not to breastfeed exclusively until six months (PR=1.70; 95% CI = 1.07-2.72). Presence of state anxiety symptoms in the postpartum period lost its association with the outcome after adjustments (PR=1.54; 95% CI = 0.97-2.44). Conclusions: Presence of trait anxiety symptoms negatively influences intention to breastfeed exclusively up to six months. Emphasis is placed on the importance of evaluating the mental health of women during pregnancy and postpartum to ensure exclusive breastfeeding is maintained. (AU)

Maternal smoking during pregnancy and offspring body mass index and overweight: a systematic review and meta-analysis.

The present study aimed to conduct a systematic review and meta-analysis to evaluate the evidence on the association of maternal smoking during pregnancy with offspring body composition in childhood, adolescence and adulthood. MEDLINE, Web of Science and LILACS databases were searched. Reference lists were also screened. We included original studies, conducted in humans, that assessed the association of maternal smoking during pregnancy with offspring body mass index (BMI) and overweight in childhood, adolescence and adulthood, published through May 1st, 2018. A meta-analysis was used to estimate pooled effect sizes. The systematic review included 64 studies, of which 37 evaluated the association of maternal smoking during pregnancy with overweight, 13 with BMI, and 14 evaluated both outcomes. Of these 64 studies, 95 measures of effect were extracted and included in the meta-analysis. We verified that the quality of evidence across studies regarding maternal smoking in pregnancy and overweight and BMI of offspring to be moderate and low, respectively. Most studies (44 studies) were classified as moderate risk bias. Heterogeneity among studies included was high and, in the random-effects pooled analysis, maternal smoking during pregnancy increased the odds of offspring overweight (OR: 1.43, 95%CI: 1.35; 1.52) and mean difference of BMI (ß: 0.31, 95%CI: 0.23; 0.39). In conclusion, offspring of mothers who smoked during pregnancy have higher odds of overweight and mean difference of BMI, and these associations persisted into adulthood.

Prevalence and determinants of the use of pacifiers and feedingbottle: a study in Southwest Bahia / Prevalência e fatores determinantes do uso de chupetas e mamadeiras: um estudo no sudoeste baiano

Abstract Objectives: to assess the use of pacifier and feedingbottle and their determinants in children from a municipality of Southwest Bahia. Methods: a cross-sectional study was performed with 354 children younger than 12 months old. The event was categorized in: exclusive use of pacifier, exclusive use of feeding bottle,use of pacifier and feeding bottle, and not use any of them. Multinomial analysis with logistic regression was applied, and those who did not use any artificial nipples were thereference variable. Results: it was observed that 11.9% of the children exclusively used pacifiers, 21.2% only use bottles and 32.8% used both of them. The following factors were associated with the exclusive use of pacifiers: low maternal schooling level (eight or less years of education), lack of previous experience with breastfeeding, difficulty in postpartum breastfeeding, and lack of incentive to breastfeeding in puericulture. The exclusive use of feeding bottle was associated with unmarried mothers, aged 35 years old or older, and with less years of education (eight or less years). Women who worked outside home and had difficulty in breastfeeding had greater chance of giving both artificial nipples to the children. Conclusions: the findingspresent different featuresrelated to the exclusive or combined use of pacifiers and feeding bottles, being important to direct health professionals conducts towards mothers' orientation.

Resumo Objetivos: avaliar o uso de chupeta e mamadeira e seus determinantes em crianças de um município da região Sudoeste da Bahia. Métodos: estudo transversal realizado com 354 crianças menores de 12 meses. O evento foi categorizado em uso de chupeta exclusivo, uso de mamadeira exclusiva, uso de chupeta e mamadeira e não faz uso de ambas. Empregou-se análise multinomial com regressão logística tendo os que não usavam bicos artificiais como variável de referência. Resultados: observou-se que 11,9% das crianças faziam uso exclusivo de chupeta, 21,2% de mamadeira, 32,8% de ambos. Estiveram associadas ao uso exclusivo de chupeta: uma menor escolaridade materna (oito ou menos anos de estudo), ausência de experiência anterior com amamentação, dificuldade de amamentar no pós-parto e falta de incentivo à amamentação na puericultura. O uso exclusivo de mamadeira foi associado a mães sem companheiro, com idade de 35 anos ou mais e com menor escolaridade (oito ou menos anos de estudo). Mulheres que trabalhavam fora do lar e que tiveram dificuldade de amamentar apresentaram maior chance de fazerem uso de ambos os bicos artificiais. Conclusões: os resultados mostram características diferentes em relação ao uso exclusivo ou conjunto de bicos e mamadeiras, sendo importantes para direcionar as condutas dos profissionais de saúde para as orientações as mães.

Resumo: Este estudo teve como objetivo realizar uma revisão sistemática e metanálise para avaliar as evidências sobre a associação entre tabagismo materno durante a gravidez e composição corporal dos filhos na infância, adolescência e vida adulta. Foram realizadas buscas nas bases de dados MEDLINE, Web of Science e LILACS, além de listas de referências. Incluímos estudos originais em seres humanos que avaliaram a associação entre tabagismo materno durante a gravidez e índice de massa corporal (IMC) e excesso de peso dos filhos na infância, adolescência e vida adulta, publicados até 1º de maio de 2018. A metanálise foi usada para estimar os tamanhos dos efeitos agregados. A revisão sistemática incluiu 64 estudos, dos quais 37 avaliaram a associação entre tabagismo materno durante a gravidez e excesso de peso, 13 com IMC e 14 com ambos os desfechos. Desses 64 estudos, foram extraídas 95 medidas de efeito, incluídas na metanálise. Verificamos que a qualidade das evidências nos estudos sobre o tabagismo materno e excesso de peso e IMC dos filhos era moderada e baixa, respectivamente. A maioria dos estudos (44) foi classificada como risco de viés moderado. A heterogeneidade entre os estudos era alta, e na análise de efeitos aleatórios agrupada, o tabagismo materno durante a gravidez aumentou a probabilidade de excesso de peso nos filhos (OR: 1,43; IC95%: 1,35; 1,52) e a diferença média do IMC (β: 0,31; IC95%: 0,23; 0,39). Conclui-se que filhos de mulheres que fumaram durante a gravidez têm maior probabilidade para excesso de peso e maior diferença média de IMC, e que essas associações persistem na vida adulta.

Prevalência de anemia e determinantes da concentração de hemoglobina em gestantes / Prevalence of anemia and determinants of hemoglobin concentration in pregnant women

Resumo Introdução A anemia é caracterizada pela reduzida concentração de hemoglobina e, durante a gestação, está associada à maior morbimortalidade fetal e materna. Objetivo Avaliar a prevalência de anemia e os fatores determinantes da concentração de hemoglobina em gestantes. Método Estudo transversal com uma amostra de 328 gestantes atendidas nas unidades de saúde urbanas de Vitória da Conquista, na Bahia. Foram realizadas a aplicação de questionário, a avaliação antropométrica e a coleta de sangue por punção capilar para dosagem de hemoglobina em β-hemoglobinômetro portátil. Foram consideradas anêmicas as gestantes com hemoglobina < 11 g/dL. Os determinantes da concentração de hemoglobina sérica foram identificados por meio da regressão linear múltipla. Resultados A prevalência de anemia foi de 18,9%, e a média de hemoglobina, de 11,9 g/dL (desvio-padrão: 1,2). Foram observadas menores médias de concentração de hemoglobina entre as gestantes que iniciaram o pré-natal no segundo trimestre (β: -0,28; IC95%: -0,54 a -0,02) e que não usavam suplemento de ferro (β: -0,51; IC95%: -0,79 a -0,23), enquanto a maior média foi verificada entre as mulheres primigestas (β: 0,34; IC95%: 0,06 a 0,62). Conclusão A anemia nas gestantes avaliadas é um leve problema de saúde pública, e as concentrações de hemoglobina foram associadas aos fatores obstétricos e à assistência pré-natal.

Abstract Background Anemia is characterized by reduced hemoglobin concentration and, during pregnancy is associated with increased fetal and maternal morbidity and mortality. Objective To evaluate the prevalence of anemia and the determinants factors of hemoglobin concentration in pregnant women. Methods Cross-sectional study with a sample of 328 pregnant women patients of the urban Health Units of Vitória da Conquista, Bahia. We applied a questionnaire, anthropometric evaluation, and collected blood by capillary puncture for dosage of haemoglobin using a portable β-hemoglobinometer. Were considered anemic those pregnant women with hemoglobin <11 g/dL. The determinants of serum hemoglobin concentration were identified through multiple linear regression. Results We observed anemia in 18.9% of the participants, and the mean hemoglobin concentration was 11.9 g/dL (standard deviation: 1.2). We observed lower mean of hemoglobin concentration among pregnant women who started prenatal care in the second trimester (β: -0.28; 95% CI: -0.54 to -0.02) and who did not used iron supplementation (β: -0.51, 95% CI: -0.79 to -0.23), while a higher mean was observed among primigavidae women (β: 0.34, 95% CI: 0.06 to 0.62). Conclusion Anemia in the population evaluated is a mild public health problem, and hemoglobin concentrations were associated to obstetric factors and prenatal care.

Conclusões: A anemia nos lactentes avaliados é um moderado problema de saúde pública, a qual está associada a fatores socioeconômicos, demográficos e dietéticos. Dessa forma, medidas são necessárias para sua prevenção.

ABSTRACT Objective: To evaluate the prevalence of anemia and the associated factors in infants assisted in health units of Vitória da Conquista, Bahia, Northeast Brazil. Methods: Cross-sectional study with a representative sample of 366 children aged 6 to 23 months. A questionnaire was applied to the caregiver, and the children's anthropometric measurements and hemoglobin levels were collected. The associations were identified by Poisson regression with robust variances based on a hierarchical analysis model. Results: The prevalence of anemia was 26.8%, and the associated factors were: family income equal to or lower than one minimum wage (PR: 1.50; 95%CI 1.03-2.18), number of household members higher than five (PR: 1.50; 95%CI 1.07-2.11), use of unfiltered water (PR: 1.68; 95%CI 1.11-2.56), number of offspring higher than three (PR: 1.64; 95%CI 1.01-2.68), consumption of meat and/or viscera less than once/week (PR: 1.78; 95%CI 1.24-2.58) and age 6-11 months (PR: 1.75; 95%CI 1.20-2.55). Conclusions: Anemia in the infants assessed is a moderate public health problem, which is associated with socioeconomic, demographic, and dietary factors; thus, measures are necessary for its prevention.

Prevalência e fatores associados à anemia em crianças de creches: uma análise hierarquizada / Prevalence and factors associated with anemia in children enrolled in daycare centers: a hierarchical analysis

RESUMO Objetivo: Determinar a prevalência e os fatores associados à anemia em crianças menores de cinco anos assistidas em creches públicas de um município no sudoeste da Bahia. Métodos: Estudo transversal com uma amostra de 677 crianças matriculadas nas creches públicas de Vitória da Conquista, Bahia. Para determinação da hemoglobina por meio de punção digital, utilizou-se hemoglobinômetro portátil, considerando-se valores de hemoglobina <11 g/dL como ponto de corte para o diagnóstico da anemia. Aplicou-se questionário aos pais ou responsáveis para coleta de informações socioeconômicas, características maternas e de saúde e nutrição da criança. Medidas antropométricas de peso e estatura foram utilizadas para avaliação do estado nutricional da criança. Análise de regressão de Poisson com variância robusta e seleção hierárquica das variáveis foi usada para verificar fatores associados com anemia. Resultados: A prevalência de anemia foi de 10,2% e houve mais prevalência nas crianças cujas moradias não apresentavam instalação sanitária (RP 3,36; IC95% 1,40-8,03); naquelas que não receberam aleitamento materno exclusivo (RP 1,80; IC95% 1,12-2,91); nas crianças com idade inferior a 36 meses (RP 1,85; IC95% 1,19-2,89) e com baixa estatura para a idade (RP 2,06; IC95% 1,10-3,85). Conclusões: A prevalência de anemia pode ser considerada um problema de Saúde Pública menor em crianças de creches populares nesse município. Crianças com condições sanitárias inadequadas, que não receberam leite materno exclusivo, bem como as em idades mais precoces e com déficit nutricional foram mais suscetíveis.

ABSTRACT Objective: To determine the prevalence and factors associated with anemia in children younger than five years old enrolled in public daycare centers in a city in southwestern Bahia, in the northeast of Brazil. Methods: This was a cross-sectional study that included a sample of 677 children enrolled in public daycare centers in Vitória da Conquista, Bahia, Brazil. A portable hemoglobinometer was used to measure hemoglobin. The concentration of <11 g/dL was considered the cutoff point for a diagnosis of anemia. A questionnaire was applied to parents/guardians in order to collect socioeconomic data, maternal characteristics and information on the child's health and nutrition. Height and weight were measured to assess the child's nutritional status. Poisson regression with robust variance and hierarchical selection of variables was used to identify factors associated with anemia. Results: The prevalence of anemia was 10.2% and was more frequent in children whose homes had no sanitary facilities (PR 3.36; 95%CI 1.40-8.03); in those who did not exclusively breastfeed (PR 1.80; 95%CI 1.12-2.91); in children aged less than 36 months (PR 1.85; 95%CI 1.19-2.89) and those who had low height for age (PR 2.06; 95%CI 1.10-3.85). Conclusions: The prevalence of anemia is considered to be a mild public health problem in the children, who are enrolled in daycare centers. Children with inadequate sanitary conditions, and that were not exclusively breastfed, as well as younger children and children with a nutritional deficit, were more likely to present the condition.
