Abstract
Introduction Alcohol consumption during pregnancy can lead to fetal alcohol spectrum disorders. This study developed and validated a questionnaire to assess university students' knowledge regarding the effects of alcohol during pregnancy. Methods We designed an instrument with true-false-I do not know statements. Initially, 45 true statements were formulated and subjected to content validation by 19 experts. Based on the Content Validity Index (CVI), 17 items were selected. The instrument, called the Fetal Alcohol Consequences Test (FACT), was first assessed by 31 university students for the level of understanding. Then, the questionnaire was administered to a national Brazilian sample of university students, and an Exploratory Factor Analysis (EFA) was conducted. Each correct FACT answer was worth 1 point, and the knowledge was categorized as high (total score ≥ 80%), moderate (score between 60 and 79%), and low (score ≤ 59%). Results When the questionnaire was being designed, the CVI values ranged from 0.779 to 1.0, and all statements were considered suitable by the target audience. For psychometric evaluation, 768 students from 24 Brazilian states participated. In the EFA, five statements were removed, revealing a tool with 12 items and two latent factors: "fetal alcohol spectrum disorders" and "conceptions and guidance on alcohol consumption during pregnancy." The KMO index (0.76426) and Bartlett's sphericity test (6362.6, df = 66, p < 0.00001) both supported the final EFA model. The goodness-of-fit indices for the factor structure were adequate: χ2 = 119.609, df = 43, p < 0.00001; RMSEA = 0.048; CFI = 0.977; TLI = 0.965. The mean total FACT score among participants was 7.71 ± 2.98, with a median of 8; 32.03% of the students had high (10-12 points), 24.09% moderate (8-9 points), and 43.88% low knowledge (<8 points). The questionnaire proved reliable, with a floor effect of 1.17%, a ceiling effect of 9.25%, and a Cronbach's alpha index of 0.798. Conclusion The FACT can be utilized in university students' health education processes, contributing to greater knowledge and information dissemination about the effects of alcohol during pregnancy, in addition to the formulation of policies on the subject directed to this group of young adults.

[PMID: 38655982 PMCID: PMC11034884 DOI: 10.1590/1516-3180.2023.0186.r1.08022024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Revised: 01/09/2024] [Accepted: 02/08/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Some maternal characteristics are related to alcohol intake during pregnancy, which irreversibly compromises the maternal-fetal binomial integrity. OBJECTIVES To identify the frequency, impact, and factors associated with alcohol consumption during pregnancy. DESIGN AND SETTING A cross-sectional study was performed at the Hospital Materno Infantil Presidente Vargas (HMIPV) in Porto Alegre/RS between March and December 2016. METHODS A structured questionnaire was administered along with a medical records review. They refer to the maternal sociodemographic and gestational status, alcohol consumption patterns, and characteristics of the fetus/newborn. In the statistical analysis, P values < 0.05 were considered significant. RESULTS The frequency of alcohol intake was 37.3%; this was characterized by the consumption of fermented beverages (89.3%), especially during the first trimester (79.6%). Risky consumption (high and/or early) occurred for 30.2% of participants. Risk factors associated with maternal alcohol consumption during pregnancy were tobacco use (P < 0.001) and abortion attempt (P = 0.023). Living with a partner (P = 0.002) and planning pregnancy (P = 0.009) were protective factors. Risky consumption was related to all of the aforementioned variables as well as threatened abortion (P = 0.023). CONCLUSIONS Alcohol intake during pregnancy is common and affects nearly one-third of pregnant women. Knowledge of the population at risk and protective factors is essential for the development of campaigns that seek to reduce consumption and, therefore, its consequences for the mother and fetus.

[PMID: 37556615 PMCID: PMC10494674 DOI: 10.1590/0102-311xpt232422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 03/20/2023] [Accepted: 04/10/2023] [Indexed: 08/11/2023] Open
Abstract
This is a national cross-sectional, hospital-based study, which interviewed 23,894 postpartum women in 2011-2012 aiming to estimate the prevalence of alcohol use during pregnancy and identifying more vulnerable groups. Alcohol use during pregnancy was identified using the TWEAK scale, and women with a score of ≥ 2 were classified as having a "presumable diagnosis of inadequate alcohol use". The national prevalence of alcohol use and the prevalence in subgroups were calculated according to maternal characteristics, with respective 95% confidence intervals (95%CI). Coexistence of smoking, inadequate prenatal consultations, and alcohol use during pregnancy were graphically identified. The prevalence of alcohol use was 14% (95%CI: 13.3-14.7), with 10% (95%CI: 9.3-10.6) of women presenting presumable diagnosis of inadequate alcohol us during pregnancy. Higher prevalence of alcohol use and presumable diagnosis of inadequate alcohol us was observed in black women, aged 12-19 years, with lower educational level, from a lower economic class, without a partner, without paid work, with more than three previous births, who did not want to get pregnant, with inadequate prenatal care, with previous delivery in public services, and who reported smoking during pregnancy. Among the interviewees, 1.2% presented all three risk factors for negative perinatal outcomes at the same time: smoking, alcohol use, and inadequate prenatal care. The results showed a high prevalence of alcohol use during pregnancy and presumable diagnosis of inadequate alcohol us, especially among women with worse social conditions. These data are relevant for the formulation of public policies to prevent alcohol use and provide support services to help this population stop alcohol use during pregnancy.

Impact of Prenatal Alcohol Exposure on the Development and Myocardium of Adult Mice: Morphometric Changes, Transcriptional Modulation of Genes Related to Cardiac Dysfunction, and Antioxidant Cardioprotection. Antioxidants (Basel) 2023; 12:antiox12020256. [PMID: 36829814 PMCID: PMC9952294 DOI: 10.3390/antiox12020256] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 01/17/2023] [Accepted: 01/18/2023] [Indexed: 01/24/2023] Open
Abstract
The impact of prenatal alcohol exposure (PAE) varies considerably between individuals, leading to morphological and genetic changes. However, minor changes usually go undetected in PAE children. We investigated PAE's effects on gene transcription of genes related to cardiac dysfunction signaling in mouse myocardium and morphological changes. C57Bl/6 mice were subjected to a 10% PAE protocol. In postnatal days 2 and 60 (PN2 and PN60), morphometric measurements in the offspring were performed. Ventricular samples of the heart were collected in PN60 from male offspring for quantification of mRNA expression of 47 genes of nine myocardial signal transduction pathways related to cardiovascular dysfunction. Animals from the PAE group presented low birth weight than the Control group, but the differences were abolished in adult mice. In contrast, the mice's size was similar in PN2; however, PAE mice were oversized at PN60 compared with the Control group. Cardiac and ventricular indexes were increased in PAE mice. PAE modulated the mRNA expression of 43 genes, especially increasing the expressions of genes essential for maladaptive tissue remodeling. PAE animals presented increased antioxidant enzyme activities in the myocardium. In summary, PAE animals presented morphometric changes, transcription of cardiac dysfunction-related genes, and increased antioxidant protection in the myocardium.

Abstract
Down syndrome is the main genetic cause of intellectual disability. Many studies describe the clinical characteristics of DS patients; however, few have investigated the clinical profile of mothers who have children with DS. Advanced maternal age (≥ 35 years old) is a risk factor for DS. Although there is an overall increase in pregnancies among women with advanced maternal age, there is still a lack of awareness of the increased risk of aneuploidy. Here, we reported the clinical and epidemiological profile of DS children and their mothers in a public reference hospital in the State of Rio de Janeiro, Brazil. For data collection, we performed a face-to-face interview guided by a structured questionnaire with closed-ended questions. A total of 344 individuals, 172 mothers and their DS children, were included in this study. Our results show that 56% of the mothers sampled were ≥ 35 years of age at childbirth. Although 98% of them received prenatal care, only 4% obtained a prenatal diagnosis of DS. Most mothers reported not drinking alcohol or smoking cigarettes during pregnancy. Furthermore, 91% of women took prenatal vitamins and supplements; however, 47% were not aware of their benefits for a healthy pregnancy. Given the strict correlation between advanced maternal age and DS, prenatal care should include genetic counseling for women over 35 years of age. This study highlights the importance of prenatal care and the urgent need for better DS screening allowing for immediate postnatal care, positively impacting the life expectancy of these patients.

Predictors of perinatal death in the presence of missing data: A birth registry-based study in northern Tanzania. PLoS One 2020; 15:e0231636. [PMID: 32298332 PMCID: PMC7161952 DOI: 10.1371/journal.pone.0231636] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 03/29/2020] [Indexed: 11/19/2022] Open
Abstract
Background More than five million perinatal deaths occur each year globally. Despite efforts put forward during the millennium development goals era, perinatal deaths continue to increase relative to under-five deaths, especially in low- and middle-income countries. This study aimed to determine predictors of perinatal death in the presence of missing data using birth registry data from Kilimanjaro Christian Medical Center (KCMC), between 2000–2015. Methods This was a retrospective cohort study from the medical birth registry at KCMC referral hospital located in Moshi Municipality, Kilimanjaro region, northern Tanzania. Data were analyzed using Stata version 15.1. Multiple imputation by fully conditional specification (FCS) was used to impute missing values. Generalized estimating equations (GEE) were used to determine the marginal effects of covariates on perinatal death using a log link mean model with robust standard errors. An exchangeable correlation structure was used to account for the dependence of observations within mothers. Results Among 50,487 deliveries recorded in the KCMC medical birth registry between 2000–2015, 4.2% (95%CI 4.0%, 4.3%) ended in perinatal death (equivalent to a perinatal mortality rate (PMR) of 41.6 (95%CI 39.9, 43.3) deaths per 1,000 births). After the imputation of missing values, the proportion of perinatal death remained relatively the same. The risk of perinatal death was significantly higher among deliveries from mothers who resided in rural compared to urban areas (RR = 1.241, 95%CI 1.137, 1.355), with primary education level (RR = 1.201, 95%CI 1.083, 1.332) compared to higher education level, with <4 compared to ≥4 antenatal care (ANC) visits (RR = 1.250, 95%CI 1.146, 1.365), with postpartum hemorrhage (PPH) (RR = 2.638, 95%CI 1.997, 3.486), abruption placenta (RR = 4.218, 95%CI 3.438, 5.175), delivered a low birth weight baby (LBW) (RR = 4.210, 95%CI 3.788, 4.679), male child (RR = 1.090, 95%CI 1.007, 1.181), and were referred for delivery (RR = 2.108, 95%CI 1.919, 2.317). On the other hand, deliveries from mothers who experienced premature rupture of the membranes (PROM) (RR = 0.411, 95%CI 0.283, 0.598) and delivered through cesarean section (CS) (RR = 0.662, 95%CI 0.604, 0.724) had a lower risk of perinatal death. Conclusions Perinatal mortality in this cohort is higher than the national estimate. Higher risk of perinatal death was associated with low maternal education level, rural residence, <4 ANC visits, PPH, abruption placenta, LBW delivery, child’s sex, and being referred for delivery. Ignoring missing values in the analysis of adverse pregnancy outcomes produces biased covariate coefficients and standard errors. Close clinical follow-up of women at high risk of experiencing perinatal death, particularly during ANC visits and delivery, is of high importance to increase perinatal survival.

Motivation for alcohol consumption or abstinence during pregnancy: A clinical-qualitative study in Brazil. PLoS One 2019; 14:e0223351.

Abstract
Background In Brazil, alcohol consumption is estimated to range from 7 to 40% in pregnant women. This research investigated the motivation for alcohol consumption or abstinence during pregnancy in a purposive sample of Brazilian women. Methods Clinical-qualitative research was conducted, in which 14 women participated, identified as risk-drinkers during pregnancy by the T-ACE screening tool. Data were collected through semi-structured individual interviews. Reports were recorded, transcribed and investigated by a thematic content analysis approach. The results were discussed based on a comprehensive and interpretive framework. Results Sixteen themes were extracted and these were then classified into three thematic categories: (a) general motives for alcohol use, (b) specific motives for drinking during pregnancy, and (c) reasons for partly or fully abstaining from drinking during pregnancy. Social motives were the most relevant, particularly due to deeply rooted cultural values. Enhancement motives were widely mentioned and associated with a hedonic posture. Consumption also aimed to deal with negative emotions, characterizing two types of coping specifically to pregnancy: first, perceiving pregnancy as a period of less opportunity for social interaction and, therefore, drinking alcohol at home to compensate; secondly, perceiving pregnancy as a period of greater irritability, and hence experiencing difficulties to abstain. On the other hand, concern about fetal health, disapproval of consumption by relatives and health professionals, as well as the social construction of mothering were reported as reasons to abstain. Conclusions Some specificities influence the decision to continue or discontinue alcohol consumption during pregnancy. To reduce consumption, we suggest educational actions based on a collective health perspective, articulated with individualized measures that allow identification and proper intervention for women at risk.
