RESUMEN

The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.


O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil.

RESUMEN

Periconceptional maternal ultra-processed food (UPF) consumption impairs embryonic growth. Impacts of exposure to UPF on distinct components of fetal growth in late pregnancy are unknown. We investigated the influence of frequency of UPF consumption during pregnancy on fetal head circumference (HC), abdominal circumference (AC) and femur length (FL). This study included 417 live-born singleton pregnancies prospectively followed-up since the antenatal period in the MINA-Brazil Study, with an available ultrasound scan at >24 gestational weeks. Frequency of food groups consumption in the previous month was categorised as no/monthly, weekly or daily. Ultrasound scans were conducted at 27·8 (sd: 1·7) gestational weeks. HC, AC and FL z-scores were calculated for gestational age using the INTERGROWTH-21st Project standards. Simultaneous-quantile regression models were fitted at the 10th, 50th and 90th percentiles of the distribution of each ultrasound parameter according to UPF consumption, with adjustment for potential confounders. Participants were aged on average 24·7 (sd: 6·5) years, 44·8 % were primiparous, and 26·9 % and 24·9 %, respectively, had weekly and daily UPF consumption. Compared with no/monthly intake, daily UPF consumption impaired HC across its distribution, with significant effect sizes varying from -0·24 to -0·40 z-score. Weekly UPF consumption decreased HC at the 90th percentile by -0·39 z-score (95 % CI: -0·78, -0·01) and FL at the 50th percentile by -0·32 z-score (95 % CI: -0·60, -0·04). No association was noted with AC. Frequency of UPF consumption was negatively associated with skeletal components of fetal growth in late pregnancy. Infant body composition may benefit from healthy food practices since pregnancy.

RESUMEN

BACKGROUND: In socially vulnerable populations, evidence is needed regarding the role of maternal nutritional status on child weight during the first 2 years of life. OBJECTIVES: We aimed to assess the association of pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with offspring BMI-for-age z-scores (BAZs) during the first 2 years of life. METHODS: A population-based birth cohort study was conducted with 900 mother-child pairs. Pre-pregnancy weight and weight at delivery were collected from medical records, and anthropometric data were measured at birth and at 6-month, 1-year and 2-year follow-up visits. Linear regression and linear mixed-effect models assessed associations with pre-pregnancy BMI, GWG and BAZ during the first 2 years of life. RESULTS: Pre-pregnancy overweight and obesity and excessive GWG were positively associated with BAZ at birth and at 1- and 2-year follow-up visits. There were no significant additional BAZ changes per year based on the exposures up to age 2 years. CONCLUSIONS: Elevated maternal pre-pregnancy BMI and GWG were associated with a child's higher BAZ at birth, and these differences remained constant throughout the first 2 years of life in Amazonian children. These findings highlight the importance of promoting adequate maternal weight before pregnancy and during prenatal care also in socially vulnerable populations.

RESUMEN

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.

RESUMEN

OBJECTIVE: To investigate the association between gestational weight gain (GWG) and perinatal outcomes in pregnant Amazonian women. METHODS: Data from 1305 mother-child pairs from the MINA-Brazil population-based birth cohort study were used. GWG was classified according to two methods, the Institute of Medicine (IOM) guidelines and INTERGROWTH-21st standards. Poisson and linear regression analyses were conducted to evaluate associations with perinatal outcomes. RESULTS: Following IOM guidelines (n = 1305), the rates of insufficient and excessive GWG were found to be similar (32%). Excessive GWG was associated with higher new-born birthweight (BW) z-scores; increased risks of macrosomia, large for gestational age (LGA), and caesarean delivery; and lower risks of low birthweight (LBW) and being small for gestational age (SGA). Insufficient GWG was associated with lower new-born BW z-scores. Among women with normal pre-pregnancy body mass indices (BMIs, n = 658), inappropriate GWG was high following both methods (IOM: 41.2% insufficient, 24.8% excessive; INTERGROWTH-21st: 25.2% below - 1 z-score, 16.9% above 1 z-score). Both methods also indicated that new-borns of women with excessive GWG had higher BW z-scores and increased risk of macrosomia and LGA. Women with GWG below the INTERGROWTH-21st standards were more likely to deliver an infant SGA and with lower BW z-scores. CONCLUSIONS: Inappropriate GWG remains a health concern irrespective of the method used to classify weight gain. GWG above the recommendations of both methods and below the INTERGROWTH-21st standard was associated with adverse perinatal outcomes. Therefore, INTERGROWTH-21st standards seem to be a better fit for healthy women in this population.

RESUMEN

BACKGROUND: Early initiation of breast feeding (EIBF) reduces the risk of neonatal mortality. However, only 45% of newborns are breast-fed within the first hour after birth and prelacteal feeding (PLF) is widely prevalent in low- and middle-income countries (LMICs). OBJECTIVE: To assess within- and between-country disparities in EIBF and PLF practices by household wealth and place of birth and to investigate the national-level correlation between these feeding indicators in LMICs. METHODS: Data from Demographic Health Surveys and Multiple Indicator Cluster Surveys (2010-2019) in 76 LMICs were used to investigate within-country disparities in EIBF, any PLF, milk-based prelacteal feeding (MPLF), and water-based prelacteal feeding (WPLF) by wealth quintiles and place of childbirth (institutional [private or public sector] or in-home) for children under two years. We examined the between-country Pearson's correlation between EIBF and types of PLF, later adjusted for per capita gross domestic product (GDP). RESULTS: No clear wealth-related differences were found for EIBF and WPLF; however, any PLF and MPLF were significantly higher in children belonging to the richest 20% of households but are also prevalent among lower income groups. Prevalence of any PLF was higher among institutional births in all LMICs, but especially for MPLF in private sector deliveries in East Asia & the Pacific, Eastern Europe & Central Asia, and Latin America & the Caribbean. WPLF was more common in all African regions. EIBF was inversely correlated with any PLF (r = -0.59, 95% CI -0.72, -0.42), MPLF (r = -0.41, 95% CI -0.58, -0.21) and WPLF (r = -0.34, 95% CI -0.53, -0.13). Adjustment for log-GDP did not affect the magnitude and direction of the results. CONCLUSION: Clear prorich disparities exist in the prevalence of PLF, especially MPLF. Children born in private sector facilities are more likely to receive MPLF. EIBF is negatively associated with PLF practices in LMICs. The promotion of better early feeding practices is urgent to achieve the Sustainable Development Goal to reduce neonatal mortality to 12 deaths per 1000 live births.

RESUMEN

OBJECTIVES: To determine predictors of 25-hydroxyvitamin D3 (25(OH)D3) concentrations (25th, 50th, and 75th percentiles) in the third trimester of pregnancy. SUBJECTS/METHODS: Data on sociodemographic, obstetric, lifestyle and pregnancy characteristics, including serum 25(OH)D3 and retinol, were collected among 448 pregnant women who participated in the Maternal and Child Health and Nutrition in Acre, Brazil (MINA-Brazil Study) in Cruzeiro do Sul, Brazilian Amazon (latitude 7°S). Simultaneous-quantile regression was fitted to prospectively assess predictors at the 25th, 50th and 75th percentiles of 25(OH)D3 concentrations. RESULTS: In the third trimester, 25(OH)D3 <50 nmol/L was observed in 26% of pregnant women. Exposure to the Amazonian dry season during follow-up and vitamin D status ≥75 nmol/L in the second trimester of pregnancy were positively associated with 25(OH)D3 concentrations in the third trimester. Pregnant women who were the main providers of family income presented lower 25(OH)D3 concentrations (50th and 75th percentiles: -15 nmol/L, 95%CI -24; -3, p = 0.02, and -22 nmol/L, 95%CI -36; -7, p = 0.004, respectively), as well as those with sustained vitamin A insufficiency (25th and 50th percentiles: -27 nmol/L, 95%CI -40; -15, p < 0.001, and -17 nmol/L, 95%CI -33; -1, p = 0.04, respectively). Sun protection practices had a smaller negative impact on 25(OH)D3, restricted to participants whose concentrations were at the 25th percentile of the distribution. CONCLUSIONS: Seasonality and vitamin A status were important predictors of 25(OH)D3 concentrations in the third trimester. Adequate exposure to sunlight and dietary sources of vitamin A within safe intake levels may help ensuring a good nutritional status of vitamin D during pregnancy.

RESUMEN

To describe the factors associated to stunting in <5-year-old Yanomami Brazilian children, and to evaluate the association of short maternal stature to their offspring's stunting. A cross-sectional study carried out in three villages in the Yanomami territory. We performed a census, in which all households with children < 5-years-old were included. The length/height-for-age z-score <-2 standard deviations was used to classify the children as stunted. Short maternal height was defined as <145 cm for adult women, and <-2 standard deviations of the height-for-age z-score for adolescent women. We used adjusted Poisson regression models to estimate prevalence ratios (PR) along the 90% confidence interval. We evaluated 298 children. 81.2% of children suffered from stunting and 71.9% of the mothers from short stature. In the bivariate analysis, a significant association of stunting with short maternal stature, gestational malaria and child's place of birth were observed. Considering the variables of the children under five years of age, there were significant associations with age group, the child's caregiver, history of malaria, pneumonia, and malnutrition treatment. In the adjusted hierarchical model, stunting was 1.22 times greater in the offspring of women with a short stature (90% CI: 1.07-1.38) compared to their counterparts. Brazilian Amazonian indigenous children living in a remote area displayed an alarming prevalence of stunting, and this was associated with short maternal height, reinforcing the hypothesis of intergenerational chronic malnutrition transmission in this population. In addition, children above 24 months of age, who were born in the village healthcare units and who had had previous treatment in the past for stunting presented higher rates of stunting in this study.

RESUMEN

The scope of this study was to investigate the factors associated with blood pressure levels among pregnant women participating in the MINA-Brazil Study, registered in the Family Health Strategy in Cruzeiro do Sul in the Western Brazilian Amazon. Multiple linear regression models were used, adopting a level of significance of 5%. The majority of pregnant participants were less than 24 years of age, 44% were primigravidae, and 59.1% had excessive weekly gestational weight gain. The frequency of hypertension was 0.7%. Factors positively associated with systolic blood pressure levels in pregnancy were pre-pregnancy body mass index (ß = 0.984, CI95%: 0.768-1.200), and weekly gestational weight gain (ß = 6.816, CI95%: 3.368-10.264). Diastolic blood pressure levels in pregnancy were positively associated with maternal age (ß = 0.111, CI95%: 0.002-0.221), maternal schooling (ß = 2.194, CI95%: 0.779-3.609), pre-pregnancy body mass index (ß = 0.589, CI95%: 0.427-0.751), and weekly gestational weight gain (ß = 3.066, CI95%: 0.483-5.650). These findings stress the importance of the role of antenatal care to prevent hypertensive disorders during pregnancy.


O objetivo deste estudo foi investigar os fatores associados aos níveis pressóricos em gestantes participantes do Estudo MINA-Brasil, inscritas no pré-natal da Estratégia de Saúde da Família em Cruzeiro do Sul, Acre, Amazônia Ocidental Brasileira. Modelos múltiplos de regressão linear foram utilizados, adotando-se nível de significância de 5%. A maioria das gestantes participantes tinha média de idade de 24 anos (DP 6,3), 44,0% eram primigestas e 59,1% das gestantes apresentaram ganho de peso gestacional semanal excessivo. A ocorrência de hipertensão arterial foi de 0,7%. Os fatores associados positivamente aos níveis de pressão arterial sistólica foram: índice de massa corporal pré-gestacional (ß = 0,984, IC95%: 0,768-1,200) e ganho de peso gestacional semanal (ß = 6,816, IC95%: 3,368-10,264). Para os níveis de pressão arterial diastólica foram positivamente associados idade da gestante (ß = 0,111, IC95%: 0,002-0,221), escolaridade (ß = 2,194, IC95%: 0,779-3,609), índice de massa corporal pré-gestacional (ß = 0,589, IC95%: 0,427-0,751) e ganho de peso gestacional semanal (ß = 3,066, IC95%: 0,483-5,650). Esses resultados reforçam a necessidade de maior atenção pré-natal no cuidado materno para prevenção de distúrbios hipertensivos no final da gravidez.

RESUMEN

OBJECTIVE: To evaluate whether weekly gestational weight gain is associated with anemia, vitamin A insufficiency, and blood pressure levels in the third trimester of pregnancy. METHODS: A prospective study with 457 pregnant women attending primary care in Cruzeiro do Sul, Acre. The weekly gestational weight gain rate measured between the second and third trimesters was classified as insufficient, adequate, and excessive according to the recommendations of the Institute of Medicine 2009. The outcomes at the beginning of the third gestational trimester were: anemia (Hb < 110 g/L), vitamin A insufficiency (serum retinol<1.05 µmol/L) and blood pressure levels (continuous values, in mmHg). Age-adjusted prevalence ratios, schooling, and use of vitamin and mineral supplements were calculated in Poisson regression models with robust variance. RESULTS: A total of 18.6% of pregnant women had insufficient weekly weight gain, and 59.1% had excessive weight gain. The frequencies of anemia, vitamin A insufficiency and hypertension (systolic blood pressure ≥ 140 mmHg or diastolic ≥ 90 mmHg) were 17.5%, 13.4%, and 0.6%, respectively. The prevalence ratios for anemia among pregnant women with insufficient and excessive weight gain were 0.41 (95%CI 0.18-0.93) and 1.00 (95%CI 0.63-1.59), respectively, when compared to pregnant women with adequate weight gain. For vitamin A insufficiency, the adjusted prevalence ratio was significantly higher among pregnant women with insufficient weight gain (2.85, 95%CI 1.55-5.24) and no difference for excessive weight gain (1.53, 95%CI 0.84-2.74) when compared to pregnant women with adequate weight gain. Pregnant women with excessive weight gain had higher mean systolic blood pressure (111.10; 95%CI 109.9-112.2) when compared to pregnant women with insufficient weight gain (107.50; 95%CI 105.4-109.6) and adequate (106.20; 95%CI 104.3-108.20). CONCLUSIONS: Insufficient weekly gestational weight gain was associated with the risk of vitamin A insufficiency. Excessive weight gain, in turn, was associated with higher blood pressure values at the beginning of the third gestational trimester.

RESUMEN

ABSTRACT OBJECTIVE To evaluate whether weekly gestational weight gain is associated with anemia, vitamin A insufficiency, and blood pressure levels in the third trimester of pregnancy. METHODS A prospective study with 457 pregnant women attending primary care in Cruzeiro do Sul, Acre. The weekly gestational weight gain rate measured between the second and third trimesters was classified as insufficient, adequate, and excessive according to the recommendations of the Institute of Medicine 2009. The outcomes at the beginning of the third gestational trimester were: anemia (Hb < 110 g/L), vitamin A insufficiency (serum retinol<1.05 μmol/L) and blood pressure levels (continuous values, in mmHg). Age-adjusted prevalence ratios, schooling, and use of vitamin and mineral supplements were calculated in Poisson regression models with robust variance. RESULTS A total of 18.6% of pregnant women had insufficient weekly weight gain, and 59.1% had excessive weight gain. The frequencies of anemia, vitamin A insufficiency and hypertension (systolic blood pressure ≥ 140 mmHg or diastolic ≥ 90 mmHg) were 17.5%, 13.4%, and 0.6%, respectively. The prevalence ratios for anemia among pregnant women with insufficient and excessive weight gain were 0.41 (95%CI 0.18-0.93) and 1.00 (95%CI 0.63-1.59), respectively, when compared to pregnant women with adequate weight gain. For vitamin A insufficiency, the adjusted prevalence ratio was significantly higher among pregnant women with insufficient weight gain (2.85, 95%CI 1.55-5.24) and no difference for excessive weight gain (1.53, 95%CI 0.84-2.74) when compared to pregnant women with adequate weight gain. Pregnant women with excessive weight gain had higher mean systolic blood pressure (111.10; 95%CI 109.9-112.2) when compared to pregnant women with insufficient weight gain (107.50; 95%CI 105.4-109.6) and adequate (106.20; 95%CI 104.3-108.20). CONCLUSIONS Insufficient weekly gestational weight gain was associated with the risk of vitamin A insufficiency. Excessive weight gain, in turn, was associated with higher blood pressure values at the beginning of the third gestational trimester.


RESUMO OBJETIVO Avaliar se o ganho de peso gestacional semanal está associado à anemia, à insuficiência de vitamina A e a níveis pressóricos no terceiro trimestre gestacional. MÉTODOS Estudo prospectivo com 457 gestantes assistidas na atenção básica em Cruzeiro do Sul, Acre. A taxa de ganho de peso gestacional semanal medida entre o segundo e o terceiro trimestres foi classificada em insuficiente, adequada e excessiva segundo recomendações do Institute of Medicine 2009. Os desfechos no início do terceiro trimestre gestacional foram: anemia (Hb < 110 g/L), insuficiência de vitamina A (retinol sérico < 1,05 µmol/L) e níveis pressóricos (valores contínuos, em mmHg). Razões de prevalência ajustadas por idade, escolaridade e uso de suplementos de vitaminas e minerais foram calculadas em modelos de regressão de Poisson com variância robusta. RESULTADOS No total, 18,6% das gestantes apresentaram ganho de peso semanal insuficiente e 59,1% ganho de peso excessivo. As frequências de anemia, insuficiência de vitamina A e hipertensão (pressão arterial sistólica ≥ 140 mmHg ou diastólica ≥ 90 mmHg) foram 17,5%, 13,4% e 0,6%, respectivamente. As razões de prevalência para anemia entre gestantes com ganho de peso insuficiente e excessivo foram 0,41 (IC95% 0,18-0,93) e 1,00 (IC95% 0,63-1,59), respectivamente, quando comparadas às gestantes com ganho de peso adequado. Para insuficiência de vitamina A, a razão de prevalência ajustada foi significantemente maior entre gestantes com ganho de peso insuficiente (2,85; IC95% 1,55-5,24) e sem diferença para ganho de peso excessivo (1,53; IC95% 0,84-2,74) quando comparada às gestantes com ganho de peso adequado. As gestantes com ganho de peso excessivo apresentaram valores médios de pressão arterial sistólica maiores (111,10; IC95% 109,9-112,2) quando comparadas às gestantes com ganho de peso insuficiente (107,50; IC95% 105,4-109,6) e adequado (106,20; IC95% 104,3-108,20). CONCLUSÕES O ganho de peso gestacional semanal insuficiente foi associado ao risco para insuficiência de vitamina A. O ganho de peso excessivo, por sua vez, foi associado a valores pressóricos maiores no início do terceiro trimestre gestacional.

RESUMEN

Introdução - Exposições adversas relacionadas ao estado nutricional na gestação têm sido associadas a desfechos desfavoráveis para a saúde materno-infantil. Nesse contexto, a deficiência de vitamina A (VA) é uma das carências nutricionais mais relevantes para a saúde dessa parcela da população, especialmente nos países em desenvolvimento. Objetivos - a) investigar preditores da concentração de retinol sérico no início do terceiro trimestre de gestação (Artigo 1), b) investigar a associação entre estado nutricional de VA durante a gestação e anemia materna no parto e peso ao nascer (Artigo 2) e c) investigar a prevalência e fatores associados com a cegueira noturna gestacional (XN) e anemia materna no parto (Artigo 3) em Cruzeiro do Sul, Acre, Amazônia Ocidental Brasileira. Métodos - Trata-se de estudo de coorte de nascimentos (MINA-Brasil: Saúde e Nutrição Materno-Infantil no Acre), a partir do recrutamento de gestantes do município. Entre fevereiro/2015 e maio/2016, gestantes inscritas no prénatal da área urbana foram rastreadas (n = 587) e dois inquéritos realizados: 1ª avaliação com 16-20 semanas de gravidez e a 2ª avaliação com 27-30 semanas de gestação. Informações sobre condições sociodemográficas, ambientais, histórico de saúde e estilo de vida, medidas antropométricas, coleta de sangue em jejum e exame de ultrassonografia foram obtidas pela equipe de pesquisa. Posteriormente, entre julho/2015 e junho/2016, foi realizado registro diário das internações para parto na única maternidade do município com coleta de informações sobre desfechos de interesse para o presente estudo. Modelos de regressão múltiplos de Poisson e lineares foram utilizados nas análises estatísticas, ao nível de significância P<0,05. Resultados - No Artigo 1 (n = 422), a presença de fumante no domicílio foi inversamente associado às concentrações de retinol sérico na gravidez (ß: -0,087; IC 95%: -0,166, -0,009); por outro lado, a sazonalidade (inverno amazônico - ß: 0,134; IC 95%: 0,063, 0,206), o consumo semanal de frutos amazônicos (ricos em carotenoides - ß: 0,087; IC 95%: 0,012, 0,162) e a concentração de retinol entre 16-20 semanas de gestação (ß: 0,045; IC 95%: 0,016, 0,074) foram positivamente associados à concentração de retinol sérico no início do terceiro trimestre gestacional. No Artigo 2 (n = 488), independente do momento avaliado na gestação, a deficiência de VA foi associada ao risco para anemia materna (RP: 1,39; IC 95%: 1,05, 1,84) e inversamente associada com as concentrações de hemoglobina materna no parto (ß: -3,34; IC 95%: -6,48, -0,20), após ajuste para covariáveis. No mesmo sentido, associação inversa também foi observada para o peso ao nascer (ß: -0,10; IC 95%: -0,20, -0,00), contudo, perdendo a significância estatística após ajuste para concentrações de ferritina plasmática. No Artigo 3 (n = 1.525), altas prevalências de cegueira noturna gestacional (11,54%) e anemia materna no parto (39,38%) foram encontradas nesta população. Os fatores associados à cegueira noturna foram o número de pessoas no domicílio (cinco ou mais- RP: 2,06; IC 95%: 1,24, 3,41), fumo na gestação (RP: 1,78; IC 95%: 1,15, 2,78) e ter realizado menos de seis consultas de pré-natal (RP: 1,61; IC 95%: 1,08, 2,40). Os fatores associados à anemia materna foram: ser adolescente (< 19 anos - RP: 1,18; IC 95%: 1,01, 1,38), malária na gestação (RP: 1,22; IC 95%: 1,01, 1,49), não ter usado suplementos na gestação (RP: 1,27; IC 95%: 1,01, 1,62) e o número de consultas de pré-natal (< 6 consultas - RP: 1,40; IC 95%: 1,15, 1,70) Conclusão - Em município da Amazônia Ocidental Brasileira, a carência de VA associou-se ao risco para anemia no parto e foi inversamente associada à hemoglobina materna e o peso ao nascer do bebê. Estratégias e ações para promoção da alimentação saudável e nutrição da mulher no pré-natal precisam ser reavaliadas visando redução dos efeitos adversos da carência de VA para o binômio mãe-filho


Introduction - Adverse exposures related to antenatal nutrition care have been associated with poor maternal and child outcomes. In this sense, vitamin A (VA) deficiency is a relevant public health issue for this vulnerable population, especially in developing countries. Objectives - a) to investigate the predictors of serum retinol at the beginning of the third trimester of pregnancy (Article 1), b) to investigate associations between the VA status during pregnancy with the occurrence of maternal anemia and birth weight (Article 2), and c) to investigate the prevalence, as well as the associated factors with gestational night blindness and maternal anemia (Article 3) in Cruzeiro do Sul, Acre State, Western Brazilian Amazon. Methods - Prospective birth cohort study (MINA-Brazil: Maternal and Child Health and Nutrition in Acre State), starting with recruitment of pregnant women. Between February/2015 and May/2016, pregnant women registered in antenatal clinics in the urban area of Cruzeiro do Sul were screened (n = 587) and two follow-up surveys were performed: the 1st one between 16 to 20 weeks of pregnancy and the 2nd one between 27 to 30 weeks of pregnancy. Socioeconomic, environmental, health history and lifestyle, anthropometric measures, blood samples, and ultrasounds data were gathered by the research team. Subsequently, between July/2015 and June/2016, daily visits to the municipal maternity hospital were performed in order to register all births and the outcomes of interest for this study. Multiple Poisson and linear regression models were used for statistical analysis, at P <0.05. Results - In the Article 1 (n = 422), having a smoker in the household was inversely associated with serum retinol in pregnancy (ß: -0.087; 95% CI: -0.166, - 0.009); on the other hand, the seasonality (Amazonian winter - ß: 0.134; 95% CI: 0.063, 0.206), the weekly consumption of Amazonian carotenoid-rich fruits (ß: 0.087; 95% CI: 0.012, 0.162), and serum retinol in the first assessment (ß: 0.045; 95% CI: 0.016, 0.074) were positively associated with serum retinol at the beginning of the third trimester of pregnancy. In the Article 2 (n = 488), regardless the period assessed, VA deficiency was associated with the risk for maternal anemia (PR: 1.39; 95% CI: 1.05, 1.84), as well as it was inversely associated with maternal serum hemoglobin (ß: -3.34; 95% CI: -6.48, - 0.20), after adjustment for covariates. Similarly, inverse association was observed for the birth weight (ß: -0.10; 95% CI: -0.20, -0.00), even though it was no longer associated after adjustment for plasma ferritin. In the Article 3 (n = 1,525), high prevalence rate of gestational night blindness (11.5%) and maternal anemia (39.4%) were observed. Associated factors with gestational night blindness were the number of people in the household (five or more- PR: 2.06; 95% CI: 1.24, 3.41), smoking during pregnancy (PR: 1.78; 95% CI: 1.15, 2.78), and the completeness of less than six antenatal care visits (PR: 1.61; 95% CI: 1.08, 2.40). Associated factors with maternal anemia were being teenage (< 19 years - PR: 1.18; 95% CI: 1.01, 1.38), gestational malaria (PR: 1.22; 95% CI: 1.01, 1.49), did not use any supplementation during pregnancy (PR: 1.27; 95% CI: 1.01, 1.62), and the number of antenatal care visits (< 6 visits - PR: 1.40; 95% CI: 1.15, 1.70). Conclusion - In a city in the Western Brazilian Amazon, the VA deficiency was associated with the risk for maternal anemia and was inversely associated with maternal serum hemoglobin and the birth weight. The current strategies and interventions targeting antenatal nutrition care must be reviewed in order to reduce the adverse effects for mother-child binomial caused by VA deficiency.

RESUMEN

OBJECTIVE: To describe the prevalence and determinants of gestational night blindness in pregnant women receiving care in a hospital in Rio de Janeiro, Brazil. DESIGN: Cross-sectional study of pregnant and postpartum women receiving care in a public hospital in Rio de Janeiro from 1999 to 2001 (group I; n 225) or from 2005 to 2008 (group II; n 381). Night blindness was identified through a standardized and validated interview (WHO, 1996). The determinants of gestational night blindness were identified through a hierarchical logistic regression model. SETTING: Public maternity hospital in Rio de Janeiro, RJ, Brazil. SUBJECTS: Adult pregnant and postpartum women (n 606), aged ≥20 years. RESULTS: The prevalence of gestational night blindness was 9·9 %. The final model revealed that not living in the South Zone of Rio de Janeiro (distal level: adjusted OR=1·846; 95 % CI 1·002, 3·401), belonging to group I (intermediate level: adjusted OR=2·183; 95 % CI 1·066, 4·471) and for the proximal level, having a history of abortion (adjusted OR=2·840; 95 % CI 1·134, 7·115) and having anaemia during the first and second trimesters of pregnancy (adjusted OR=3·776; 95 % CI 1·579, 9·029) were determinants of gestational night blindness. CONCLUSION: Gestational night blindness should be assessed for during the prenatal care of all pregnant women, especially those living in deprived areas of the city and/or who have a history of abortion or anaemia. Nutritional monitoring is recommended during pregnancy to control gestational night blindness.

RESUMEN

RESUMO: Objetivo: Avaliar o impacto da suplementação com vitamina A (VA) em gestantes e puérperas adultas no Brasil sobre o teor de VA e imunoglobulina A secretora (IgAS) do colostro e leite materno, nas condições de saúde infantil e no status de VA do binômio mãe-filho. Métodos: Realizou-se uma busca eletrônica nas bases MEDLINE, Scopus , Web of Science e Lilacs por estudos publicados entre janeiro de 2000 e janeiro de 2014. A qualidade metodológica dos estudos foi avaliada conforme a escala de Jadad. A busca pelas publicações ocorreu em janeiro de 2014 de forma independente por dois autores. Resultados: Encontraram-se sete estudos sobre os efeitos da suplementação com VA no puerpério sobre leite materno e morbidade infantil. Nenhum estudo com suplementação em gestantes foi detectado. A suplementação no puerpério elevou o teor de retinol no leite materno, aumentando a oferta de VA para a criança, e também a concentração de IgAS no colostro. Efeitos sobre a redução na morbidade infantil não foram descritos. Conclusão: Constata-se que os benefícios descritos sobre a suplementação no pós-parto ainda não foram completamente evidenciados no programa brasileiro, embora a suplementação contribua para a melhora do estado nutricional de VA da criança e da puérpera e na oferta da vitamina, pelo leite materno, ao recém-nascido.


ABSTRACT: Objective: To assess the impact of vitamin A supplementation on adult pregnant and puerperal women in Brazil regarding the content of vitamin A and secretory immunoglobulin A on colostrum and breast milk, in child's health conditions, and in mother-child binomial vitamin A status. Methods: A research was conducted in Medline, Scopus, Web of Science, and Lilacs electronic databases for the studies published between January 2000 and January 2014. The methodological quality of the studies was assessed according to Jadad scale. The study search was conducted in January 2014, independently by two authors. Results: Seven studies were found concerning the effects of vitamin A supplementation in the puerperal period on breast milk and infant morbidity. No study regarding pregnant women supplementation was found. The supplementation in the puerperal period raised the retinol content on breast milk, thus increasing the offer of vitamin A for the child and the concentration of secretory immunoglobulin A on colostrum. There was no description of effects on infant morbidity. Conclusion: It seems that the advantages of postpartum supplementation were not established in the Brazilian program, although the supplementation contributes to a better nutritional status of vitamin A for both the child and the puerperal woman and increases the offer of vitamin A for the newborn through the breast milk.

RESUMEN

Introduction: In developing countries, night blindness is a very common public health problem among pregnant women. Objective: Evaluate the effect of the changes occurred on prenatal care concerning prenatal nutritional care on the occurrence of night blindness (XN) in adult pregnant women in public maternity hospital in Rio de Janeiro between 1999-2001 and between 2007-2008. Methods: Two cross-sectional studies were conducted, been the first one conducted between 1999-2001 and the second one between 2007-2008. Were studied 402 puerperal women, 225 between 1999-2001 (GI) and 177 between 2007-2008 (GII). The gestational XN was investigated during the immediate puerperium (GI) and during the prenatal/puerperium (GII), diagnosed by the World Health Organization. The study collected sociodemographic, clinical, obstetric, anthropometric and prenatal care information. Results: It verified significant reduce of prevalence of gestational XN (GI = 18.7% e GII = 0.6%, p < 0.001). The occurrence of gestational XN was associated to sanitary conditions, education level, more than six prenatal consultations, miscarriage at last pregnancy, higher average number of deliveries, average number of prenatal care consultations and prenatal nutritional (p < 0.05). There was no association between gestational XN and marital status, skin color, pre-gestational nutritional status, adequacy of gain of total gestational weight, gestational anaemia and average number of pregnancies (p > 0.05). Conclusion: The inclusion of nutritional care in routine prenatal care may have contributed to the reduction of gestational XN. Studies to assess the nutritional intervention in the prevention and treatment of gestational XN at regions at greatest risk are suggested (AU)


Introducción: En los países en desarrollo, la ceguera nocturna (CN) es un problema muy común de la salud pública entre las mujeres embarazadas. Objetivo: Evaluar el efecto de los cambios ocurridos en la atención prenatal sobre el cuidado nutricional prenatal sobre la aparición de CN en mujeres adultas embarazadas en una maternidad pública en Rio de Janeiro entre 1999-2001 y entre 2007-2008. Métodos: Se realizaron dos estudios transversales, el primero entre 1999-2001 y el segundo entre 2007-2008. Se estudiaron 402 mujeres puérperas, 225 entre 1999-2001 (GI) y 177 entre 2007-2008 (GII). La CN gestacional fue investigada durante el puerperio inmediato (GI) y durante el prenatal/puerperio (GII), diagnosticada por la Organización Mundial de La Salud. El estudio incluyó informaciones sociodemográficas, clínicas, obstétricas, antropométricas y del cuidado prenatal. Resultados: Se verificó reducción significativa de la prevalencia de CN gestacional (GI = 18,7% e GII = 0,6%, p < 0,001). La ocurrencia de CN gestacional se asoció con las condiciones sanitarias, el nivel de educación, más de seis consultas prenatales, abortos espontáneos en el último embarazo, mayor número promedio de partos, el número promedio de consultas de atención prenatal y de nutrición prenatal (p < 0,05). No hubo asociación entre CN gestacional y el estado civil, color de piel, estado nutricional pregestacional, adecuación de la ganancia de peso durante la gestación, incluyendo anemia gestacional y el número medio de embarazos (p > 0,05). Conclusión: La inclusión de la atención nutricional en el cuidado prenatal de rutina puede haber contribuido para la reducción de CN gestacional. Se sugiere más estudios para evaluar la intervención nutricional en la prevención y el tratamiento de CN gestacional en las regiones de mayor riesgo (AU)

RESUMEN

Introduction: Several methods of dietetic counseling can be used in the nutritional therapy in gestational diabetes mellitus (GDM). The main methods are the traditional method (TM) and the carbohydrate counting (CCM). Objective: Presenting a systematic review of the literature on the impact of nutritional therapy in GDM, through TM and CCM, evaluating the results for maternal and child health. Methods: We searched databases PubMed, Scopus, Web of Science, Lilacs and CAPES Digital Bank of Thesis. The methodological quality of all the studies included was made using the Jadad score. Results and conclusion: We have found five studies that evaluated the effects of nutritional therapy, through the TM, on the maternal and child health. None study evaluating the CCM was detected in pregnant women with GDM Nutritional therapy given during antenatal care was effective in reducing pregnancy complications (preeclampsia, excessive gestational weight gain, necessity for cesarean delivery, for insulin therapy and for shoulder dystocia), perinatal complications (macrosomia, neonatal hypoglycemia, and birth weight) and also in better glycemic control. The use of nutritional therapy should be highlighted within the antenatal care for pregnant women with GDM, giving the satisfactory results on metabolic control and on pregnancy outcomes. Studies examining the CCM to GDM patients should be conducted to show its effects on maternal and child health (AU)


Introducción: Diversos métodos de asesoramiento dietético pueden ser utilizados en la terapia de la nutrición en la diabetes mellitus gestacional (DMG). Los principales son el método tradicional (MT) y el contaje de hidratos de carbono (MCHC). Objetivo: Presentar una revisión sistemática de la literatura sobre el impacto de la terapia nutricional en el DMG, utilizando el MT y MCHC, la evaluación de los resultados para la salud materna e infantil. Métodos: Se realizó una búsqueda electrónica a través de las siguientes bases de datos: PubMed, Scopus, Web of Science, Lilacs y CAPES Banco Digital de Tesis. La calidad metodológica de todos los estudios incluidos se evaluó mediante la escala de Jadad. Resultados y Conclusiones: Se encontraron cinco estudios que evaluaron los efectos de la terapia nutricional utilizando el método tradicional, en la salud de la mujer embarazada y su feto. No se detectó ningún estudio que tenga evaluado el MCHC en las mujeres embarazadas con DMG. La terapia nutricional durante la atención prenatal fue eficaz em la reducción de las complicaciones del embarazo (pre-eclampsia, aumento excesivo de peso, necesidad de parto por cesárea, terapia con insulina y distocia de hombros), las complicaciones perinatales (macrosomía, hipoglucemia neo natal, peso al nacimiento) y también en un mejor control glucémico. El uso de la terapia nutricional debe ser destacada en la atención prenatal para las mujeres embarazadas con DMG, dados los resultados satisfactorios en el control metabólico y complicaciones en el embarazo. Los estudios que evalúan el MCHC en las mujeres embarazadas con DMG deben llevarse a cabo para mostrar sus efectos en la salud materna e infantil (AU)

RESUMEN

Determinar o perfil lipídico de mulheres adultas e avaliar a sua relação com os índices antropométricos relacionados à adiposidade central.Métodos: Estudo transversal, conduzido em uma clínica-escola de nutrição de uma universidade pública de Minas Gerais, com 47 mulheres adultas em lista de espera para atendimento. Avaliaram-se as concentrações de colesterol total (CT), lipoproteína de alta densidade (HDL), lipoproteína de baixa densidade (LDL), lipoproteína de muito baixa densidade (VLDL), triglicerídeos (TG), peso, estatura,circunferência da cintura (CC) e circunferência do quadril (CQ). Calculou-se o índice de massa corporal (IMC) e a relação cintura-quadril(RCQ). A análise da associação entre concentrações séricas de lipídeos e variáveis de adiposidade ocorreu através do coeficiente de correlação de Pearson. Resultados: Do total de voluntárias, 22 (51,2%) apresentaramníveis de CT acima dos valores limítrofes e 18 (41,9%) apresentaram LDL elevada. A proporção de indivíduos com VLDL e TG elevados foi relativamente inferior (n=4; 9,3% en=10; 23,3%, respectivamente). A CC e a RCQ se correlacionaram positivamente com os níveis de VLDL e TG (p<0,05). Nas voluntárias com IMC ≥ 25 kg/m², a prevalência de dislipidemias foi de 39,5% (n=17) e a CC se correlacionou positivamente com os níveis de CT (p = 0,04). Conclusão:Os resultados apontaram relação entre os lipídeos séricos e as medidas de adiposidade central, com frequências importantes de dislipidemias nas mulheres investigadas, especialmente níveis elevados de CT e LDL...


To access the lipid profile of adult women and to evaluate its relationship with anthropometric measures concerning the central adiposity. Methods: Cross-sectional study, conducted in a clinical school of nutrition at a public university in Minas Gerais, comprising 47 adult women who were on the waiting list for the service. The concentrations of total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), triglycerides (TG), and weight, height, waist circumference (WC) and hip circumference (HC) were evaluated. The body mass index (BMI) and waist-hip ratio (WHR) were calculated. Analysis of the association of serum lipids to adiposity variables occurred through the Pearson correlation coefficient. Results: Of the volunteers,22 (51.2%) had TC levels above theborderline values and 18 (41.9%) had high LDL. The proportion of subjects with elevated VLDL and TG levels was relatively low (n=4; 9.3% and n=10; 23.3%, respectively). The WC and WHR were positively correlated with the VLDL and TG levels (p <0.05). Among volunteers with BMI ≥ 25 kg/m², the prevalence of dyslipidemia was 39.5% (n=17) and WC was positively correlated with TC levels (p = 0.04).Conclusion: Results pointed out an association of serum lipids to the measures of central adiposity, withimportant frequencies of dyslipidemia in the women under investigation, especially high levels of TC and LDL...


Determinar el perfil lipídico de mujeres adultas y evaluar su relación con los índices antropométricos relacionados con la adiposidad central.Métodos: Estudio trasversal realizadoen una clínica-escuela de nutrición de una universidad pública de Minas Gerais, con 47 mujeres adultas del listado de espera de consulta. Se evaluó las concentraciones de colesterol total(CT), lipoproteína de alta densidad (HDL), lipoproteína de baja densidad (LDL), lipoproteína de muy baja densidad (VLDL), triglicéridos (TG), peso, altura, circunferencia de la cintura(CC) y circunferencia de la cadera (CC). Se calculó el índice de masa corporal (IMC) y la relación cintura-cadera (RCC). El análisis de la asociación entre las concentraciones séricas de lípidos y variables de adiposidad se dio a través del coeficiente de correlación de Pearson. Resultados: Del total de voluntarias, 22 (51,2%) presentaron niveles de CT por encima de los valoreslimítrofes y 18 (41,9%) presentaron LDL elevado. La proporción de individuos con VLDL y TG elevados fue relativamente bajo (n=4; 9,3% y n=10; 23,3%, respectivamente). La CC y la RCC se correlacionaron positivamente con los niveles de VLDL y TG (p<0,05). En las voluntarias con el IMC ≥ 25 kg/m², la prevalencia de dislipidemias fue del 39,5% (n=17) y la CC se correlacionó positivamente con los niveles de CT (p = 0,04).Conclusión: Los resultados señalaron relación de los lípidos séricos y lasmedidas de adiposidad central con frecuencias importantes dedislipidemias en las mujeres investigadas, especialmente niveleselevados de CT y LDL...
