Factors Influencing Duration of Breastfeeding: Insights from a Prospective Study of Maternal Health Literacy and Obstetric Practices.

Numerous factors concerning early breastfeeding abandonment have been described, including health literacy (HL). This study's objective was to analyze factors related to early breastfeeding abandonment (<6 months). This prospective multicentric study examined the duration of breastfeeding at 6 months postpartum and was conducted in four different regions of Spain from January 2021 to January 2023. A total of 275 women participated in this study, which focused on maternal HL and obstetric practices. A decrease in the breastfeeding rate was observed from hospital discharge (n = 224, 81.5%) to the sixth month postpartum (n = 117, 42.5%). A Cox regression analysis revealed that inadequate HL levels, lack of mobilization during labour, and induced labour were significantly associated with early breastfeeding cessation (p = 0.022, p = 0.019, and p = 0.010, respectively). The results highlight that women with adequate HL had a 32% lower risk of early breastfeeding abandonment. In comparison, mobilization during labour and induction of labour were linked to a 32.4% reduction and a 53.8% increase in this risk, respectively. These findings emphasize the importance of considering obstetric and HL factors when addressing the breastfeeding duration, indicating opportunities for educational and perinatal care interventions.

Evaluation of the Impact of a Midwife-Led Breastfeeding Group Intervention on Prevention of Postpartum Depression: A Multicentre Randomised Clinical Trial.

Postpartum depression is a significant health issue affecting both mothers and newborns during the postpartum period. Group support interventions during this period have proven effective in helping women cope with depression and improving breastfeeding rates. This study aimed to assess the effectiveness of a midwife-led breastfeeding support group intervention on breastfeeding rates, postpartum depression and general self-efficacy. This was a multicentric cluster randomised controlled trial with control and intervention groups and was not blinded. It was conducted in Andalusia (southern Spain) from October 2021 to May 2023. A total of 382 women participated in the study. The results showed a significant difference in exclusive breastfeeding rates at 4 months postpartum between the groups (control 50% vs. intervention 69.9%; p < 0.001). Additionally, there was a lower mean score on the Edinburgh Postnatal Depression Scale in the intervention group (12.49 ± 3.6 vs. 13.39 ± 4.0; p = 0.044). Similarly, higher scores of general self-efficacy were observed among breastfeeding women at 2 and 4 months postpartum (77.73 ± 14.81; p = 0.002 and 76.46 ± 15.26; p < 0.001, respectively). In conclusion, midwife-led breastfeeding support groups enhanced self-efficacy, prolonged breastfeeding and reduced postpartum depression 4 months after giving birth.

Effects of a mobile application on breastfeeding maintenance in the first 6 months after birth: Randomised controlled trial (COMLACT study).

PROBLEM: It is necessary to continue promoting breastfeeding rates. BACKGROUND: Information and communication technologies have significantly impacted healthcare services and are transforming the sector. There is little evidence of the usefulness of mobile applications to support breastfeeding and increase its duration. AIM: To assess whether mobile application-LactApp® (Barcelona, Spain)-usage compared with standard care increases the 6-month postpartum breastfeeding rate. METHODS: A multicentre, randomised, controlled clinical trial of parallel groups was conducted. The study was conducted in four public hospitals in Spain from January 2022 to January 2023. 270 Women were randomly assigned to each parallel group. The women in the intervention group received free access to the mobile application LactApp®, which provides personalised and convenient support to women about BF. Women in the control group received standard care, which included individual counselling about the benefits of maintaining BF for the first 6 months of the baby's life. FINDINGS: The rate of breastfeeding abandonment at 15 days was 6.4 % in the control group vs 0.0 % in the intervention group (p = 0.105). LactApp® usage did not increase the 6-month postpartum breastfeeding rate compared with standard care (CG = 41.6% vs. IG = 43.6 %; p = 0.826). DISCUSSION: Further studies must explore how technologies can help improve long-term breastfeeding maintenance. The mobile app seems to reduce early weaning in the first 15 days slightly. CONCLUSION: Mobile application usage did not increase the breastfeeding rate compared with standard practice but may reduce breastfeeding abandonment in the first 2 weeks postpartum.

Perinatal Outcomes at Birth in Women Infected and Non-Infected with SARS-CoV-2: A Retrospective Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) was declared as a pandemic and public health emergency on 11 March 2020 by the World Health Organization. Different clinical trials on the efficacy of mRNA vaccination have excluded pregnant women, leading to a lack of empirical evidence on the efficacy of the vaccine in this population. The aim of the study was to examine the association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection at birth and adverse perinatal outcomes in infected and non-infected women from a university hospital in Spain. METHODS: The data were obtained from electronic health records from 1 March 2020 to 28 February 2022. A bivariate descriptive analysis was performed, comparing women with and without confirmed SARS-CoV-2 infection during pregnancy using the chi-square test. A multivariate logistic regression was complementarily conducted to determine whether SARS-CoV-2 infection increases the risk of adverse obstetric and perinatal outcomes. RESULTS: A total of 2676 women were divided into two groups: non-infected with SARS-CoV-2 (n = 2624) and infected with SARS-CoV-2 (n = 52). Infected women were primarily multiparous (p < 0.03) and had received an incomplete vaccination regimen (p < 0.001). A greater incidence of premature rupture of membranes (p < 0.04) was observed among the non-infected women. Pertaining to perinatal outcomes, there was a notable rise in NICU admissions (p < 0.014), coupled with an extended duration of stay (p < 0.04), for neonates born to infected mothers in comparison to their non-infected counterparts. CONCLUSION: Although SARS-CoV-2 infection may pose significant risks to pregnant women and their infants, adverse obstetrical/puerperal outcomes do not significantly differ between women infected and non-infected to SARS-CoV-2 in our study. NICU admissions were higher for neonates born to infected mothers. Additionally, coronavirus disease 2019 vaccination during pregnancy is not associated with severe adverse perinatal outcomes.

Exploring home births in Catalonia (Spain): A cross-sectional study of women's experiences and influencing factors.

AIM: The study explores the experiences of women with low-risk pregnancies and no complications who planned a home birth. DESIGN: A cross-sectional study was conducted using an online questionnaire. METHODS: The questionnaire included socio-demographic, obstetric and perinatal variables. Birth satisfaction was evaluated via the Spanish version of the childbirth experience questionnaire. The study group comprised home-birthing women in Catalonia, Spain. Data were collected from 1 January 2019 to 31 December 2021. Statistical analysis was performed using SPSS. RESULTS: A total of 236 women responded. They reported generally positive experiences, with professional support and involvement being the most highly rated dimensions. Better childbirth experiences were associated with labour lasting less than 12 h, no perineal injuries, no intrapartum transfers to hospital, euthocic delivery and the presence of a midwife. CONCLUSIONS: Women's positive home birth experiences were linked to active participation and midwife support. Multiparous women felt safer. Medical interventions, especially transfers to hospitals, reduced satisfaction, highlighting the need for improved care during home births. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Home births should be included among the birthplace options offered by public health services, given the extremely positive feedback reported by women who gave birth at home. IMPACT: Home birth is not an option offered under Catalonia's public health system only as a private service. The experience of home-birthing women is unknown. This study shows a very positive birth experience due to greater participation and midwife support. The results help stakeholders assess home birth's public health inclusion and understand valued factors, supporting home-birthing women. REPORTING METHOD: The study followed the STROBE checklist guidelines for cross-sectional studies. PUBLIC CONTRIBUTION: Women who planned a home birth participated in the pilot test to validate the instrument, and their contributions were collected by the lead researcher. The questionnaire gathered the participants' email addresses, and a commitment was made to disseminate the study's results through this means.

Indications of Induction and Caesarean Sections Performed Using the Robson Classification in a University Hospital in Spain from 2010 to 2021.

Background: The Robson Ten Group Classification System (RTGCS) enables the assessment, monitoring, and comparison of caesarean section rates both within healthcare facilities and between them, and the indications of caesarean sections (CS) performed in a maternity ward. The aims of the present study were to conduct an analysis to assess the levels and distribution of birth from a descriptive approach by CS in La Ribera University Hospital (Spain) between 2010-2021 using the Robson classification; to describe the indications for the induction of labour and the causes of caesarean sections performed; and to examine the association between the induction of labour and CS birth. Methods: A retrospective study between 1 January 2010 and 31 December 2021. All eligible women were classified according to the RTGCS to determine the absolute and relative contribution by each group to the overall CS rate. The odds ratio (OR) of the variables of interest was estimated by logistic regression. In an analysis of the subgroups, the level of significance was adjusted using the Bonferroni method. Results: 20,578 women gave birth during the study period, 19% of them by CS. In 33% of births, induction was performed, and the most common cause was the premature rupture of membranes. Group 2 (nulliparous with induced labour/elective CS before labour) accounted for the largest contribution to the overall rate of CS (31.5%) and showed an upward trend from 23.2% to 39.7% in the time series, increasing the CS rate by 6.7%. The leading cause of CS was suspected fetal distress, followed by induction failure. Conclusions: In our study, Robson Group 2 was identified as the main contributor to the hospital's overall CS rate. Determining the causes of induction and CS in a population sample classified using the RTGCS enables the identification of the groups with the greatest deviation from the optimal rate of CS and the establishment of improvement plans to reduce the overall rate of caesarean sections in the maternity unit.

Effect of Mobile-Based Counselling on Breastfeeding in Spain: A Randomized Controlled Trial Protocol (COMLACT Study).

PURPOSE: The primary aim of this study is to determine the influence of an intervention in women based on a free mobile application (LactApp®, Barcelona, Spain) in maintaining breastfeeding (BF) up to 6 months postpartum. The secondary aim is to assess the effect of health literacy (HL) on breastfeeding duration. METHODS: A multicenter, randomized controlled clinical trial of parallel groups will be carried out. Women will be randomly assigned to each of the parallel groups. In the control group, usual clinical practice will be followed from the third trimester of pregnancy to promote BF. In the intervention group, and in addition to usual clinical practice, the women will use a free mobile application (LactApp®) from the third trimester to 6 months postpartum. The type of BF at birth, at 15 days and at 3 and 6 months postpartum and the causes of cessation of BF in both groups will be monitored. The hypothesis will be tested using inferential analysis, considering an alpha of 5%. The study protocol was approved by the Clinical Research Ethics Committee of Hospital de la Ribera (Alzira, Valencia, Spain) in February 2021. A per protocol analysis and an intention-to-treat analysis will be performed. DISCUSSION: This study will identify the influence of a mobile application on improving BF rates. If the application proves effective, we will have a tool with free information available to any user at any time of day, which may be complemented by normal clinical practice and be integrated into our health care system. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT05432700.

Development and Validation of the Breastfeeding Literacy Assessment Instrument (BLAI) for Obstetric Women.

BACKGROUND: Despite international efforts to protect and promote exclusive breastfeeding (EBF) for infants up to six months of age, global rates of EBF continue to fall short of the targets proposed by the WHO for 2025. Previous studies have shown a relationship between the level of health literacy and the duration of EBF, although this relationship was not determinant, probably due to the use of a generic health literacy questionnaire. Therefore, this study aims to design and validate the first specific breastfeeding literacy instrument. METHODS: A Breastfeeding Literacy instrument was developed. Content validation was carried out by a group of 10 experts in health literacy, breastfeeding or instrument validation, obtaining a Content Validity index in Scale (S-CVI/Ave) of 0.912. A multicentre cross-sectional study was carried out in three Spanish hospitals to determine the psychometric properties (construct validity and internal consistency). The questionnaire was administered to 204 women during the clinical puerperium. RESULTS: The Kaiser-Meier-Oklin Test (KMO = 0.924) and Bartlett's Test of Sphericity (X2 = 3119.861; p ≤ 0.001) confirmed the feasibility of the Exploratory Factor Analysis, which explained 60.54% of the variance with four factors. CONCLUSIONS: The Breastfeeding Literacy Assessment Instrument (BLAI) consisting of 26 items was validated.

Is Early Initiation of Maternal Lactation a Significant Determinant for Continuing Exclusive Breastfeeding up to 6 Months?

BACKGROUND: The World Health Organization (WHO) recommends early initiation of breastfeeding (EIBF) within the first hour after birth. However, certain perinatal factors, namely caesarean section, may prevent this goal from being achieved. The aim of our study was to examine the relationship between EIBF (maternal lactation in the first hours and degree of latching before hospital discharge) and the maintenance of exclusive breastfeeding (MBF) up to the recommended 6 months of age (as advocated by the WHO). METHODS: This observational, retrospective cohort study included a random sample of all births between 2018 and 2019, characterising the moment of breastfeeding initiation after birth and the infant's level of breast latch (measured by LATCH assessment tool) prior to hospital discharge. Data were collected from electronic medical records and from follow-up health checks of infants up to 6 months postpartum. RESULTS: We included 342 women and their newborns. EIBF occurred most often after vaginal (p < 0.001) and spontaneous births with spontaneous amniorrhexis (p = 0.002). LATCH score <9 points was associated with a 1.4-fold relative risk of abandoning MBF (95%CI: 1.2-1.7) compared with a score of 9-10 points. CONCLUSIONS: Although we were unable to find a significant association between EIBF in the first 2 h after birth and MBF at 6 months postpartum, low LATCH scores prior to discharge were associated with low MBF, indicating the importance of reinforcing the education and preparation efforts of mothers in the first days after delivery, prior to the establishment of an infant feeding routine upon returning home.

Influence of Health Literacy on Maintenance of Exclusive Breastfeeding at 6 Months Postpartum: A Multicentre Study.

Background: International organizations recommend initiating breastfeeding within the first hour of life and maintaining exclusive breastfeeding for the first 6 months. However, worldwide rates of exclusive breastfeeding for 6-month-old infants is far from meeting the goal proposed by the World Health Organization, which is to reach a minimum of 50% of infants. Education is one of the factors affecting the initiation and continuation of breastfeeding, and incidentally, it is also related to lower health literacy. This study explored the influence of health literacy on maintenance of exclusive breastfeeding at 6 months postpartum. Methods: A longitudinal multicenter study with 343 women were recruited between January 2019 and January 2020. The first questionnaire was held during the puerperium (24−48 h) with mothers practicing exclusive breastfeeding, with whom 6-month postpartum breastfeeding follow-up was performed. Socio-demographic, clinical and obstetric variables were collected. Breastfeeding efficiency was assessed using the LATCH breastfeeding assessment tool. The health literacy level was evaluated by the Newest Vital Sign screening tool. A multivariate logistic regression model was used to detect protective factors for early exclusive breastfeeding cessation. Results: One third of the women continued exclusive breastfeeding at 6 months postpartum. Approximately half the participants had a low or inadequate health literacy level. An adequate health literacy level, a high LATCH breastfeeding assessment tool score (>9 points) and being married were the protective factors against exclusive breastfeeding cessation at 6 months postpartum. Conclusion: Health literacy levels are closely related to maintaining exclusive breastfeeding and act as a protective factor against early cessation. A specific instrument is needed to measure the lack of "literacy in breastfeeding", in order to verify the relationship between health literacy and maintenance of exclusive breastfeeding.

Obstetric-Neonatal Care during Birth and Postpartum in Symptomatic and Asymptomatic Women Infected with SARS-CoV-2: A Retrospective Multicenter Study.

This study analyses the obstetric−neonatal outcomes of women in labour with symptomatic and asymptomatic COVID-19. A retrospective, multicenter, observational study was carried out between 1 March 2020 and 28 February 2021 in eight public hospitals in the Valencian community (Spain). The chi-squared test compared the obstetric−neonatal outcomes and general care for symptomatic and asymptomatic women. In total, 11,883 births were assisted in participating centers, with 10.9 per 1000 maternities (n = 130) infected with SARS-CoV-2. The 20.8% were symptomatic and had more complications both upon admission (p = 0.042) and during puerperium (p = 0.042), as well as transfer to the intensive care unit (ICU). The percentage of admission to the Neonatal Intensive Care Unit (NICU) was greater among offspring of symptomatic women compared to infants born of asymptomatic women (p < 0.001). Compared with asymptomatic women, those with symptoms underwent less labour companionship (p = 0.028), less early skin-to-skin contact (p = 0.029) and greater mother−infant separation (p = 0.005). The overall maternal mortality rate was 0.8%. No vertical transmission was recorded. In conclusion, symptomatic infected women are at increased risk of lack of labour companionship, mother−infant separation, and admission to the ICU, as well as to have preterm births and for NICU admissions.

A comparison between midwifery and obstetric care at birth in Spain: Across-sectional study of perinatal outcomes.

BACKGROUND: The organizational structure of maternity services determines the choice of which professionals provide care during pregnancy, birth, and the postnatal period, and it influences the kind of care they deliver and the level of continuity of care offered. There is considerable evidence that demonstrates a relationship between how care is provided and the maternal and neonatal health outcomes. Registered midwives and obstetricians provide maternity care across Spain. To date, no studies have assessed whether maternity outcomes differ between these two groups. OBJECTIVE: The aim of this study was to examine the association between the care received (midwifery care versus obstetric care) and the maternal and neonatal outcomes in women with normal, low- and medium-risk pregnancies in Spain from 2016 to 2019. DESIGN: A prospective, multicentre, cross-sectional study was carried out as part of COST Action IS1405 at 44 public hospitals in Spain in the years 2016-2019. The protocol can be accessed through the registry ISRCTN14062994. The sample size of this study was 11,537 women. The primary outcome was mode of birth. The secondary outcomes included augmentation with oxytocin, use of epidural analgesia, women's position at birth, perineal integrity, third stage of labour management, maternal and neonatal admission to intensive care, Apgar score, neonatal resuscitation, and early initiation of breastfeeding. Chi-square tests for categorical variables and independent sample t-test for continuous variables to assess differences between the midwifery and obstetric groups were calculated. Odds ratio with intervals of confidence at 95% were calculated for obstetric interventions and perinatal outcomes. A multivariate logistic regression model was applied in order to examine the effect of type of healthcare provider on perinatal outcomes. These models were adjusted for care provider, type of onset of labour, use of anaesthesia, pregnancy risk, maternal age, parity, and gestational age at birth. RESULTS: Midwifery care was associated with lower rates of operative births and severe perineal damage and had no higher adverse outcomes. No statistically significant differences were observed in the use of other obstetric interventions between the two groups. CONCLUSIONS: The findings of this study should encourage a shift in the current maternity care system towards a greater integration of midwifery-led services in order to achieve optimal birth outcomes for women and newborns. REGISTRY NUMBER: ISRCTN14062994.

Manejo del parto, el puerperio y la lactancia en mujeres positivas para SARS-CoV-2. Estudio multicéntrico en la Comunidad Valenciana / Management of labour, puerperium, and lactation in SARS-CoV-2 positive women. Multicentric study in the Valencian Community

Objetivo: Determinar las repercusiones maternas y perinatales de las gestantes con reacción en cadena de la polimerasa positiva para SARS-CoV-2 durante el parto y el puerperio clínico. Método: Estudio observacional descriptivo, retrospectivo y multicéntrico realizado mediante la revisión de historias clínicas de las gestantes ingresadas por parto desde el 1 de marzo hasta el 30 de junio de 2020. Resultados: Se analizaron 13 mujeres con reacción en cadena de la polimerasa positiva a SARS-CoV-2. La prevalencia de casos positivos fue del 0,48% sobre el total de partos atendidos en el periodo de estudio. Ninguna de las madres desarrolló complicaciones derivadas de la infección por COVID-19 ni necesitó ingreso en la Unidad de Cuidados Intensivos. El 15,4% de los partos terminó en cesárea, el 7,7% fueron prematuros, el 53,8% de los recién nacidos fueron aislados de su madre, en el 61,5% se realizó pinzamiento tardío del cordón umbilical y la tasa de lactancia materna exclusiva al alta fue del 76,9%. Todos los recién nacidos fueron negativos a COVID-19 mediante reacción en cadena de la polimerasa y no tuvieron complicaciones posteriores al parto. Conclusiones: No ha quedado constatada la transmisión vertical durante el parto en los recién nacidos de madres positivas a COVID-19. Han sido detectadas prácticas clínicas no avaladas por la evidencia científica al inicio de la pandemia que han ido adaptándose a las recomendaciones internacionales a medida que esta evolucionaba.(AU)

Objective: To determine the maternal and perinatal impact of pregnant women with SARS-CoV-2 positive polymerase chain reaction during childbirth and post clinical period. Method: Observational descriptive, retrospective, and multicentre study carried out through the review of clinical records of pregnant women admitted for delivery from 1 March to 30 June 2020. Results: Thirteen women with SARS-CoV-2 positive polymerase chain reaction were tested. The prevalence of positive cases was 0.48% of the total number of births attended during the study period. None of the mothers developed complications from COVID-19 infection, nor did they require admission to the Intensive Care Unit. Of the births,15.4% ended in caesarean section, 7.7% were premature, 53.8% of the newborns were isolated from their mothers, 61.5% had late clamping of the umbilical cord and the rate of exclusive breastfeeding at discharge was 76.9%. All the newborns were polymerase chain reaction-negative for COVID-19 and had no postpartum complications. Conclusions: Vertical transmission during childbirth in newborns of COVID-19 positive mothers has not been reported. Clinical practices not supported by scientific evidence were detected at the beginning of the pandemic and adapted to international recommendations as the pandemic evolved.(AU)

Health literacy and its relation to continuing with breastfeeding at six months post-partum in a sample of Spanish women.

AIM: To explore the relation between health literacy (HL) and continuing breastfeeding (BF) at 6 months post-partum. DESIGN: Observational, longitudinal and prospective study between December 2018-May 2019. The STROBE checklist was used. METHODS: 114 mother/baby pairings from a Spanish Hospital were included. Mothers' health literacy was studied with the Newest Vital Sign and Short Assessment of Health Literacy for Spanish Adults 50 (SAHLSA-50). Before hospital discharge, BF efficiency was studied using the LATCH BF score and BF continuity was followed for 6 months. Survival analysis and Cox regression were done. RESULTS: Health literacy levels and BF effectiveness were adequate before hospital discharge. At 6 months post-partum, less than half the sample still exclusively breastfed. The main reason for early exclusive BF cessation was lower than the recommended newborn weight gain. The HL level acted as a protective factor against abandonment of BF.

Recomendaciones internacionales estándar sobre la ganancia de peso gestacional: adecuación a nuestra población / Standard international recommendations for gestational weight gain: suitability for our population

INTRODUCCIÓN: la ganancia de peso gestacional (GPG) es uno de los indicadores que más se utilizan en el control prenatal y quizás sea el factor que más influya en los resultados perinatales. OBJETIVO: determinar hasta qué punto se ajusta la GPG de las gestantes del Departamento de Salud de la Ribera (Valencia) a los estándares internacionales de GPG recomendados por el Institute of Medicine (IOM) de EE. UU. MÉTODOS: estudio observacional retrospectivo sobre una muestra de 4361 mujeres cuyo parto tuvo lugar en el Hospital Universitario de la Ribera entre el 1 enero de 2010 y el 31 de diciembre de 2015. Las gestantes se clasificaron en función de la GPG según las recomendaciones internacionales: incremento de peso adecuado, superior e inferior. RESULTADOS: una mayor GPG recomendada aumenta el riesgo de terminar el parto en cesárea o en parto instrumentado (OR = 1,454, p < 0,001; OR = 1,442, p < 0,001, respectivamente), y de obtener un recién nacido macrosómico o grande para la edad gestacional (OR = 3,851, p = 0,008; OR = 1,749, p < 0,001, respectivamente) con respecto a obtener una GPG adecuada. La GPG está relacionada con el peso al nacer (p < 0,001). CONCLUSIONES: las recomendaciones de GPG emitidas por el IOM se adaptan en general a las gestantes de nuestro entorno. Se ha constatado que una GPG distinta a dichas recomendaciones aumenta la probabilidad de tener resultados perinatales desfavorables. Sin embargo, es necesaria una aproximación más personalizada, adaptando las recomendaciones internacionales al control prenatal en cada una de las categorías de IMC pregestacional

BACKGROUND: gestational weight gain (GWG) is one of the most commonly used indicators in prenatal care, and probably the most influential factor in perinatal outcomes. OBJECTIVE: to determine the extent to which the GWG of pregnant women from the Ribera Health Department (Valencia) meets GWG international standards as recommended by the U.S. Institute of Medicine (IOM). METHODS: a retrospective observational study of a sample of 4,361 women who gave birth at Hospital Universitario de la Ribera between January 1, 2010 and December 31, 2015. Pregnant women were classified according to GWG international recommendations: adequate weight gain, above and below. RESULTS: a higher GWG increases the risk of cesarean delivery or instrumental delivery (OR = 1.454, p < 0.001; OR = 1.442, p < 0.001, respectively), and of having a macrosomic or larger newborn for gestational age (OR = 3.851, p = 0.008; OR = 1.749, p < 0.001, respectively) as compared to an appropriate GWG. GWG is related to birth weight (p < 0.001). CONCLUSIONS: the GPG recommendations issued by the IOM are generally well adapted to pregnant women in our environment. It has been found that a GPG other than these recommendations increases the probability of obtaining poor perinatal outcomes. Nevertheless, a more personalized approach is needed, adapting international recommendations to prenatal control for each of the pre-pregnancy BMI categories

Attitudes of Undergraduate Nursing Students towards Patient Safety: A Quasi-Experimental Study.

Improving nursing students' attitudes towards patient safety is a current and relevant topic. This study aims to evaluate the effectiveness of an educational intervention based on critical incident and root cause analysis (RCA) techniques regarding attitudes towards patient safety in nursing students. A quasi-experimental before and after study was developed between January 2018 and December 2019 in a sample of 100 nursing students at Universitat Jaume I (Spain). The intervention was developed in two phases. Phase I was at university, where students applied the RCA technique in a real case. Phase II took place during clinical practice. Students used critical incidents to identify a risk situation for the patients and applied RCA to detect its root causes. The measurement of attitudes was performed with the Attitudes to Patient Safety Questionnaire (APSQ-III). The global score of the questionnaire in the baseline measurement was 3.911 (±0.335), in the intermediate measurement it was 4.031 (±0.337) and in the final measurement it was 4.052 (±0.335), with significant differences (p = 0.03). However, intra-group differences were observed in the final measurement (p = 0.021). The teamwork dimension had the highest mean score on all three measures and the notification dimension had the lowest mean scores. An educational intervention combining critical incident and RCA techniques can improves nursing students' attitudes toward patient safety.

La GPG está relacionada con el peso al nacer (p < 0,001). Conclusiones: las recomendaciones de GPG emitidas por el IOM se adaptan en general a las gestantes de nuestro entorno. Se ha constatado que una GPG distinta a dichas recomendaciones aumenta la probabilidad de tener resultados perinatales desfavorables. Sin embargo, es necesaria una aproximación más personalizada, adaptando las recomendaciones internacionales al control prenatal en cada una de las categorías de IMC pregestacional.
