Prevalence of gestational diabetes and recourse to postpartum oral glucose tolerance test in the Autonomous Province of Trento (Italy).

OBJECTIVE: The occurrence of gestational diabetes (GDM) is increasing worldwide, and such a diagnosis is important for women's health beyond pregnancy. Therefore, many guidelines suggest the re-evaluation of glucose tolerance with a postpartum oral glucose tolerance test (OGTT) in women with GDM. This study reports the prevalence of GDM and the use of a postpartum OGTT in women assisted at maternity units in the Autonomous Province of Trento in the years 2017-2018, investigating the socio-demographic and health-care variables that can facilitate access to the test. STUDY DESIGN: For the diagnosis of GDM, the International Association of Diabetes and Pregnancy Study Group criteria were used. The Birth Assistance Certificate and the Hospital Information System were used to retrieve clinical and socio-demographic data. Univariate and multivariate analyses were performed to evaluate the stratification of the use of a postpartum OGTT. RESULTS: In total, 8,308 pregnant women were assisted at the maternity units in Trento. There were 532 recorded cases of GDM (266 cases per year) and the overall average prevalence was 6.4 % (95 % CI, 5.90-6.90), 4.9 % of whom were Italian (95 % CI, 4.38-5.42) and 10.4 %, foreigners (95 % CI, 9.13-11.67). 135 women diagnosed with GDM and residing in Trento out of 513 were evaluated using a postpartum OGTT (26.3%, CI 95% 22.50-30.10), with pathological results in 61 cases (45.2%). In the multivariate analyses, insulin therapy during pregnancy, delivery at a third-level birth point, and a discharge letter informing of the presence of GDM and of the need for a postpartum OGTT were independent factors associated with the probability of carrying out a postpartum OGTT. CONCLUSIONS: The prevalence of GDM in our study is lower than in previous Italian studies; however, it is consistent with European data. The proportion of women who were assessed using the postpartum OGTT is lower than that reported by previous studies. The health-care factors seem predominant among the socio-demographic characteristics of the cases in influencing access to the test. The awareness of women, the sharing of guidelines among the different sectors of the health system, and an optimal management of the discharge from the birth point are critical in ensuring an optimal follow-up in women with GDM.

Screening of group B Streptococcus infection in pregnancy and neonatal outcomes in the province of Trento, Italy.

The study analyzes the trend of group B streptococcal (GBS) infection in pregnancy in the province of Trento, Italy, where a universal screening of GBS infection in pregnancy has been active for some time. Data from pregnant women who gave birth at local maternity units between 2015-2019 were obtained from birth attendance certificates (BAC), the main - and mandatory - source of information for monitoring pregnancies, births and neonatal health in Italy. The BAC used in the province of Trento acquires the results of a vast range of infections in pregnancy. The data collected from the BAC were integrated with those provided by the Hospital Information System (SIO). The occurrence of neonatal GBS infection was investigated on 2019 birth cohort, using the hospital discharge archive as an ancillary information source. Between 2015-2019, 20,905 pregnant women received care at maternity units of the province of Trento, Italy, of whom 25.5% were foreigners. The average coverage of GBS testing in pregnancy was 91.8% (95% CI 91.25-92.35) without significant variations from one year to the next. Test coverage varies in relation to maternity units and some socio-demographic characteristics of mothers. The average proportion of GBS positive cases over the study period was 21.0% (95% CI 20.7-21.3), a value that does not show statistically significant changes from one year to the next. The proportion of positive cases appears uneven among the subgroups of pregnant women considered, even if the differences are not statistically significant. In the 2019 birth cohort, newborns to GBS-positive mothers had an excess of stillbirths, of those born with Apgar at 5 minutes <7 and hospitalized at birth. However, these excesses were not statistically significant. Intravenous Antibiotic Prophylaxis (IAP) was performed in 86.8% of births from GBS positive mothers who had an indication for IAP. IAP was inadequate in 7.4% of the GBS positive mothers. Postnatal evaluation of 783 live births to GBS positive mothers identified 3 cases of early neonatal GBS infection. The incidence of neonatal GBS infection over the whole series of live births is 0.71/1,000 (95% CI 0.56-0.86), 0.68/1000 (CI 95% 0.55-0.79) in Italians and 1.07/1000 (95% CI 0.45-1.65) in foreigners. Data collection on infections in pregnancy through BAC allows area-based assessment. The quality of the data recorded in the BAC can be considered satisfactory but it was necessary to access to other information sources. The local availability of various information sources should allow periodic audits and closer monitoring of neonatal GBS infection.

Esiti avversi perinatali correlati all'indice di massa corporea pregravidico.

BACKGROUND: a high body mass index (BMI) during pregnancy has been associated with an increased risk of complications and adverse outcomes for both mother and infant. OBJECTIVES: to analyse the main adverse maternal and neonatal outcomes associated with maternal excess weight and obesity. DESIGN: retrospective epidemiological study. SETTING AND PARTICIPANTS: data extrapolated from the Birth Attendance Certificate information flow of the Autonomous Province of Trento (Northern Italy) between 2015 and 2019. A total of 20,756 women with data regarding maternal height and weight at the start of pregnancy were included in the analysis. MAIN OUTCOME MEASURES: gestational outcome variables studied were gestational diabetes, hypertensive disorders, premature birth, and still births. Outcomes considered during labour and delivery were type of delivery, induction, episiotomy and post-partum haemorrhage. Neonatal outcomes were birth weight, Apgar score, need for resuscitation, and hospitalisation in the neonatal intensive care unit (NICU). Lastly, exclusive breastfeeding at discharge was analysed. RESULTS: considering the population of pregnant women, 68.3% of women were classified as normal-weight, 9.5% as underweight, 16.0% as overweight, and 6.3% as obese. Maternal excess weight and obesity were seen to be associated with an increased risk of gestational diabetes, gestational hypertension, preeclampsia, caesarean section, induction, post-partum bleeding, foetal macrosomia, and the need for neonatal resuscitation and hospitalisation in the NICU. Infants born to overweight and obese mothers were also less likely to be breastfed. CONCLUSIONS: excess weight and obesity are important risk factors for health and contribute to the onset of complications during pregnancy and adverse perinatal and long-term outcomes. Programming and implementing public health promotion schemes aimed at preventing excessive weight gain in the reproductive age could significantly improve maternal and foetal health.

Rubella immunity status and the active offer of MMR/MMRV vaccination during pregnancy.

INTRODUCTION: The rubella test during pregnancy makes it possible to identify situations at risk of congenital rubella and those pregnant mothers who should be offered the MMR vaccine. MATERIALS AND METHODS: The Authors analysed test coverage and the immunity status of pregnant mothers between 2005 and 2017, using birth attendance certificates. RESULTS: Rubella test coverage on 61,437 pregnant mothers was 99.4%. The average proportion of susceptible subjects was 6.4%. Seroconversion was observed in 7 cases, with 1 confirmed case of congenital rubella. 32% of susceptible subjects were vaccinated, and adherence was seen to be influenced by the characteristics of the pregnant women and of the maternity unit. CONCLUSIONS: A current information flow including a number of healthcare services, is useful both for monitoring the maternity care pathway and for public health purposes.

Coverage and outcomes of antenatal tests for infections: a population based survey in the Province of Trento, Italy.

BACKGROUND: Rubella, syphilis, toxoplasmosis, cytomegalovirus (CMV), hepatitis B (HBV) and C (HCV), HIV, and Group B Streptococcus (GBS) infections may have very severe outcomes during pregnancy, and for this reason, monitoring of infections in pregnant women is a requirement of prenatal assistance. AIMS: To describe coverage and outcome of the screening for rubella, syphilis, toxoplasmosis, CMV, HBV, HCV, HIV, and Group B Streptococcus in pregnancy in the Autonomous Province of Trento, Northern Italy (538,600 inhabitants). METHODS: We analysed the coverage and outcome of the above-mentioned screenings among women who delivered in the hospitals of the Province of Trento between 2007 and 2014 (N = 38,712). Screenings were grouped according to characteristics such as recommendation by national and local guidelines, scheduling of the tests, operating methods, and charge. We also estimated odds ratios (ORs) for missing screening for selected infections through multiple logistic regression. RESULTS: Estimated uptake of antenatal screening was 99.7% for rubella, 99.3% for syphilis, 99.7% for toxoplasmosis, 98.1% for HIV infection, 99.0% for HBV, 98.9% for HCV, 94.0% for GBS infection, and 75.4% for CMV infection. The overall prevalence of immunity was 94.1% for rubella, 24.2% for toxoplasmosis, and 64.2% for CMV. The rate of seroconversion in pregnant women was 0.02% for rubella, 0.29% for toxoplasmosis, and 0.75% for CMV. The overall prevalence of infection was 0.94% for HBV, 0.53% for HCV, 22.3% for GBS, 0.29% for syphilis, and 0.13% for HIV. We found a significant positive association for all screening tests, between lack of testing and late first medical examination in pregnancy (ORs ranging from 1.20 to 1.66 for the first medical visit in the second trimester and ORs ranging from 1.60 to 5.88 for the first medical visit in third trimester, compared to early medical visit in the first trimester). Compared to Italian citizenship, foreign citizenship of the mother was also positively associated with absence of screening (ORs ranging from 1.30 to 1.53). A significant inverse association was observed for calendar year of delivery (ORs ranging from 0.71 to 0.97, for 1 year increment). Less educated mothers and pluriparae were also at higher risks of not being tested. Analysis of the association with mother age showed different heterogeneous effects. CONCLUSIONS: Our study indicates that the attention to screening and detecting infected cases is growing over the time. In addition, care delivered during pregnancy has a leading role in determining coverage of the examinations. Immigrant, pluriparous and less educated women need particular attention.

Breastfeeding during the first year of life: estimates using records generated in general pediatrics.

BACKGROUND: The monitoring of breastfeeding during a child's first year of life is highly recommended. The proportion of children who are exclusively breastfed for at least six months is a strong indicator of breastfeeding promotion in the community. The objectives of the study were to survey the exclusive breastfeeding of children during the first year of life for cohorts born in Trentino (north-eastern Italy) in 2009 to 20013, to evaluate the decrease of exclusive breastfeeding at 6 months and to analyze possible relationships between the maintenance of breastfeeding up to the age of 6 months and certain maternal socio-demographic characteristics, as well as clinical aspects of the pregnancy and birth. METHODS: Cohorts born in Trentino between 2009 and 2013 were studied, calculating the proportion of infants who were breastfed upon discharge from the hospital (source: data on the CedAP informative flow, that is the Italian Certificate of Delivery Assistance data-base). The data provided on the 12-Month Health Evaluation Form found in the Pediatric Health Booklet, completed by regional family pediatricians, was linked with that of the respective CedAP (96.7% linkage). The trend for exclusive breastfeeding and its monthly decrease was analyzed. The maintenance of exclusive breastfeeding until the age of 6 months was analyzed in relation to citizenship, area of residence, maternal education level and employment status, parity, single or multiple birth, infant exposure to passive smoke and attendance or non-attendance of a state-promoted childbirth preparation course. This final variable was studied solely for primiparous women, who are generally most likely to attend a childbirth preparation course. All results were adjusted for the following potential confounding variables: "birth type," "prematurity" and "feeding method upon discharge from the hospital." RESULTS: CedAP data revealed that 83.5% of live infants were exclusively breastfed and that this percentage decreased to 34.7% by the age of 6 months (35.4% among full-term infants and 27% among premature infants). Data from the Province of Trento demonstrates that exclusive breastfeeding up to the age of 6 months is influenced by the mother's citizenship, area of residence and education level, but not by her employment status. In addition, the study revealed a significant association with parity, passive smoke exposure and attendance of a childbirth preparation course. CONCLUSIONS: The Pediatric Health Booklet with its information on the state of health of children (in combination with data from the CedAP) offers a valid tool for monitoring breastfeeding during the first year of life. Data confirmed a decrease in the rate of breastfeeding between birth and the first month of life and between the first and sixth months of living at home. The results regarding the conditions that favour and discourage breastfeeding suggest potential public health care measures to improve children's health.

[The usefulness of emergency room data for integrated surveillance of spontaneous abortion at population level]. / L'utilità dei dati di pronto soccorso per una sorveglianza integrata dell'abortività spontanea a livello di popolazione.

OBJECTIVES: to quantify and identify the proportion of miscarriages in the province of Trento (Trentino-Alto Adige Region, Northern Italy) in 2010-2016, managed exclusively at the emergency room (ER). DESIGN: population surveillance study. SETTING AND PARTICIPANTS: comparison between the Trentino computerized database of registration to the ER for miscarriage and the flow D-11 of the Italian National Statistics Institute (Istat) on hospitalized miscarriages in the period 2010-2016. MAIN OUTCOME MEASURES: for each year, the proportion of women seen at the ER for miscarriage and then hospitalized and the cases exclusively managed in ER were calculated. The two groups were compared on the basis of the following variables: age, citizenship, gestational week, calendar year, and ER of admission. RESULTS: the proportion of miscarriages managed exclusively in ER in the province of Trento varies from 31.3% in 2010 to 60.5% in 2016. There are no differences in the proportion of hospitalization in relation to the age of women, while a higher proportion of hospitalizations was observed among foreign women compared to the Italians and in the ER of Trento compared to the peripheral ERs. A growing trend of hospitalization clearly appears with increasing gestational age, while the calendar year is inversely proportional to the increase in hospitalization. CONCLUSIONS: since the therapeutic diagnostic path of women with miscarriage has changed, it could be useful to have a representation as close as possible to the reality of the phenomenon to evaluate if an integration of the Istat D-11 flow on the cases hospitalized with those cases managed exclusively in ER is feasible or opportune. This opportunity should be considered in local, multicentre or national epidemiological studies.

[Antenatal course attendance among primiparous mothers, with physiological pregnancy and birth at term in Trentino (Northern Italy): characteristics of non-attender women and benefits among attender women in pregnancy behaviours, type of birth delivery and neonatal outcomes]. / La partecipazione al corso d'accompagnamento alla nascita tra le madri primipare con gravidanza fisiologica e parto a termine in Trentino: caratteristiche delle donne non partecipanti e benefici tra le partecipanti rispetto ad abitudini in gravidanza, modalità del parto, esiti neonatali.

OBJECTIVE: to outline the attendance rate of antenatal classes (ANCs) among women resident in Trentino Region (North-Eastern Italy) during the period 2000-2012; to identify the main sociodemographic characteristics of women who do not attend ANCs and to measure the effectiveness of ANCs attendance. DESIGN: cohort study with a retrospective data collection. SETTING AND PARTICIPANTS: by the computerised database of Trentino Certificates of delivery care, primiparous mothers living in Trentino presenting a physiological pregnancy and birth at term (≥37 weeks of gestation) were selected. Temporal trends of ANCs attendance were also studied for all mothers living in Trentino, all primiparous residents, all multiparous residents and all residents with foreign citizenship. MAIN OUTCOME MEASURES: possible associations between the probability of not attending ANCs and sociodemographic variables concerning mothers were analysed: age, professional status, educational level, marital status, citizenship and residence in an area served by a maternal and child health (MCH) clinic or not. Significant relationships between ANCs attendance and variables related to course of pregnancy, childbirth and neonatal outcomes were identified. RESULTS: ANCs coverage has a statistically significant increasing trend over time for each group of women living in Trentino. Among the selected primiparous pregnant women, the principal barriers to ANCs access are being foreign, having an age ≤30 years, in particular ≤20 years, being housewives or unemployed, presenting a medium-low educational level, and residing in an area not served by a MCH clinic. ANCs-not-attending women show a lower awareness of the importance of performing serological tests for Syphilis and Cytomegalo-virus and they declare smoking in pregnancy. Benefits of ANCs attendance do not affect neonatal outcomes, but they concern a higher probability of vaginal birth and a higher breastfeeding predisposition. CONCLUSION: data about ANCs attendance in Trentino Region appear higher than other national-regional studies. However, there are significant differences in access to ANCs regarding women's sociodemographic characteristics and resources distribution and MCH clinics measurement. In Italy, an evaluation about the accessibility of MCH clinics and their functioning criteria is desirable, focusing on marketing practices towards lower classes women. In Trentino, virtuosos MCH clinics have introduced elastic times in the ANCs planning and they have involved cultural mediators and private gynaecologists. Younger pregnant women are included in the ANCs after a preliminary meeting or by individual paths.
