Oral supplementation of α-lipoic acid (ALA), magnesium, vitamin B6 and vitamin D stabilizes cervical changes in women presenting risk factors for preterm birth.

OBJECTIVE: Recently, the PTB risk has been related to the objective measurement of cervical length (CL), since a CL of less than 25 mm is an accurate predictor of increased risk of PTB. Primary prevention of preterm labor is based on the early identification of symptoms and on pharmacological treatments with tocolytic drugs for inhibition of uterine contractions that are associated with a shortening of the cervix. Unfortunately, most of these drugs have important side effects. PATIENTS AND METHODS: This study aimed to evaluate whether the administration of a combination of oral α-lipoic acid (ALA), magnesium, vitamin B6 and vitamin D to pregnant women presenting risk factors for PTB could reduce the rate of cervical shortening at 19-22 weeks of gestational age. RESULTS: A total of 122 women attending the first-trimester aneuploidy screening at 11-14 weeks of pregnancy and presenting risk factors for PTB were included in the study. Cervical length significantly decreased in the control group compared with the treatment group (-3.86 ± 1.97 vs. 1.50 ± 1.26; p=0.02). Although the rate of preterm birth did not significantly decrease (9.5% vs. 5.1%), admission for threatened PTB was statistically reduced in the treatment group compared with the control group (3.4% vs. 14.3%). CONCLUSIONS: Oral supplementation of ALA, magnesium, vitamin B6 and vitamin D significantly counteracted cervix shortening in pregnant women presenting risk factors for PTB.

First-trimester prediction of gestational hypertension through the bioelectrical impedance analysis of the body composition.

OBJECTIVE: Obesity is a risk factor for the development of gestational hypertension, with important consequences for both the mother and fetus. This prospective observational study aims to propose an early prediction model of hypertensive disorders in pregnancy among obese women, through the bioelectrical impedance analysis (BIA) at the first trimester, thus allowing early recognition of obese women that are at risk to develop gestational hypertension, in order to target preventive interventions. PATIENTS AND METHODS: Singleton obese women (BMI ≥ 30 kg/m2) between the 9th and 12th week of pregnancy were included in the study. The exclusion criteria were chronic diseases, like type 2 diabetes mellitus, hypertension, and other medical pre-existing conditions. Eligible women were followed up at 20, 28, and 36 weeks of gestation by measuring blood pressure, weight, and body composition with the use of the BIA. The diagnosis of gestational hypertension was made after the 20th week of gestation. Pregnancy and perinatal outcomes were then recorded. RESULTS: Of the 479 women included in the study, 85 (17.7%) developed gestational hypertension; the remaining 394 (82.3%) resulted to be normotensive. A higher rate of nulliparous women was found in the hypertensive group (50.6% vs. 37.6%, p = 0.02), together with a higher rate of induction of labor (55.3% vs. 40.9%, p = 0.02) and of small for gestational age (SGA) newborns (12.9% vs. 6.9%, p = 0.03). Significant differences emerged in the body composition between the two groups already from the first trimester, indeed women developing gestational hypertension showed elevated values of Total body Mass, FM, FFM, TBW (p < 0.02), and of leg's FM, FFM (p < 0.006). At the multivariate logistics regression, the risk of developing gestational hypertension resulted higher in women with elevated total body water levels in the first trimester (OR 1.10 95% CI 1.04 -1.92). CONCLUSIONS: The BIA is a rapid, easy, non-invasive, and inexpensive tool to evaluate the body composition of obese pregnant women. It represents a promising predictor of hypertensive disorders in pregnancy, which allows an early identification of the patients at risk of developing gestational hypertension, thus opening a window of opportunity for strictly monitoring and target preventive intervention.

Physical activity in low risk pregnant women: a cross-sectional study.

OBJECTIVES: The aim of this study is to analyze the quality and quantity of physical activity (PA) practiced by low-risk pregnant women before and during pregnancy. DESIGN: This cross-sectional study assesses the dietary habits, exercise habits and body mass index. We used an ad hoc health lifestyle multiple choice questionnaire. The data collection lasted 7 months, from the beginning of September 2018 to the end of March 2019. POPULATION: We recruited 175 Italian women with a singleton, low-risk pregnancy at 32-36 weeks of gestational age. RESULTS: In the periconceptional period, 52.6 % of women do not perform any PA. For the other 47.4% of women, the most practiced activities, both before and during gestation, are walking and swimming. Data on the sedentariness showed that about a quarter of the population remains inactive watching TV for more than two hours a day. Interestingly, the most statistically significant risk factor for sedentariness is the BMI > 25 kg/m². Therefore, overweight or obese women are more likely to maintain a sedentary lifestyle during pregnancy. CONCLUSIONS AND IMPLICATION FOR THE PRACTICE: Our study highlighted a high rate of sedentariness in pregnancy, especially among overweight and obese women. Thus, it is important to undertake interventions aimed at informing pregnant women of various benefits that PA can bring. In particular, because of the significant association between sedentariness and BMI greater than 25 kg/m2, it results crucial to direct these recommendations particularly to overweight/obese pregnant women, addressing them to a healthy lifestyle.
