Special Issue Information

Dear Colleagues,

This Special Issue, entitled "Nutrition and Food Safety in Pregnancy",  is an essential resource for anyone interested in the intersection of maternal nutrition and food safety. We call for articles that focus on the importance of adequate nutrition and food safety during pregnancy. The issue aims to provide researchers, health professionals, and policymakers a platform to share and discuss the latest basic and evidence-based research, practices, and interventions that promote optimal nutrition and food safety during pregnancy.

The issue covers a broad range of topics, including topics among this non-comprehensive list:

  • The effects of nutrition in complicated pregnancies such as diabetic pregnancy;
  • The impact of maternal nutrition on maternal, fetal, and infant health;
  • The role of dietary supplements and micronutrients in pregnancy;
  • The effects of gestational weight gain on maternal and fetal health;
  • The issues of food safety in preventing pregnancy complications.

We hope that the articles in the Special Issue provide insights into current research on the latest nutrition and food safety practices for pregnant women. They will also examine the challenges of implementing evidence-based nutrition and food safety interventions in clinical and community settings. Additionally, the Special Issue will highlight the need for collaborative efforts among healthcare providers, policymakers, and researchers to develop and implement effective strategies to improve maternal and fetal nutrition and food safety.

Objective: Both short and long sleep durations are associated with decreased kidney function; however, few studies have examined the relationship between sleep, hydration status, and plain water intake. This study aimed to assess the relationship between sleep quality, hydration status, and plain water intake in pregnant women. Methods: A cross-sectional study method was used to collect data from 380 pregnant women with regular examinations at the hospital between May 2019 and February 2021. Results: There were statistically significant differences in daily plain water intake (x2 = 14.118, p = 0.001), PSQI score (x2 = 77.708, p < 0.001), sleep duration (x2 = 67.569, p > 0.001), subjective sleep quality (x2 = 67.441, p = 0.001), time to fall asleep (x2 = 64.782, p < 001), sleep disorders (x2 = 70.853, p < 0.001), and daytime dysfunction (x2 = 38.441, p < 0.001) among different hydration status groups. Ordinal logistic regression results indicated that the intake of plain water ≥1500 mL/d (OR = 0.40, 95% CI = 0.24~0.67), good subjective sleep quality (OR = 0.15, 95% CI = 0.07~0.32), short time to fall asleep (OR = 0.32, 95% CI = 0.14~0.70), 8 h of sleep (OR = 0.06, 95% CI = 0.02~0.17), 6–7 h of sleep (OR = 0.19, 95% CI = 0.07~0.54), no sleep disturbance (OR = 0.31, 95% CI = 0.11~0.89), and high sleep efficiency (OR = 0.46, 95% CI = 0.03~0.79) were factors that were correlated with optimal hydration status. Sleep duration and daytime dysfunction partially mediated the effect of plain water intake on hydration status. The mediating effect of sleep duration was −0.036, accounting for 14.006% of the overall effect. The mediating effect of daytime dysfunction was −0.024, accounting for 9.459% of the overall effect. Conclusion: The hydration status in pregnant women may be affected by daily plain water intake and sleep quality. Full article

Fluid intake and hydration status during pregnancy may have influences on maternal and infant health. However, few studies have recorded and analyzed total fluid intake (TFI) levels during the whole pregnancy. This study mainly aimed to investigate the TFI levels of pregnant women in three trimesters, and further to assess their hydration status. The relationships of TFI and hydration status were also analyzed. A convenience sampling method was used to recruit pregnant women from the Haikou Maternity and Child Health Hospital in China in this prospective cohort study. A 7-day 24 h fluid intake questionnaire was used for recording the fluid intake of the participants in their three trimesters. Fasting blood samples and first morning urine samples were also collected and tested. Hydration status was evaluated using urine osmolality. Finally, 142 pregnant women completed the study. The median TFIs in the first, second, and third trimesters were 1336, 1477, and 1584 mL, respectively. The TFI levels increased with pregnancy progression (χ2 = 134.155, p < 0.05). Out of 142 participants, 100.0%, 97.2%, and 85.2% of participants did not reach the recommendation amount for an adequate TFI among Chinese pregnant women in the three trimesters, respectively (χ2 = 29.840, p < 0.05). Plain water was the main source of fluid intake, accounting for 92.0%, 94.2%, and 93.4% of TFI, respectively. The median values of dairy product intake were 61, 57, and 59 mL in the three trimesters. The frequency of participants without an optimal hydration status in the three trimesters was 71.8%, 76.1%, and 83.1%, respectively (χ2 = 29.909, p < 0.05). The participants of each trimester were divided into four groups according to quartiles of TFI, including participants with a lower fluid intake (LFI1 and LFI2) and higher fluid intake (HFI1 and HFI2). As the TFI values increased from the LFI1 group to the HFI2 group, the urine osmolality decreased (all p < 0.05). Moderate-intensity negative correlations were found between urine osmolality, hydration status, and TFI (all p < 0.05). It is suggested that fluid intake strategies should be promoted and health education should be conducted to improve the hydration status of pregnant women. Full article

This study aimed to investigate whether the effects of an exercise program during pregnancy on postpartum body composition are moderated by following a healthy dietary pattern (i.e., Mediterranean diet (MD)). Eighty-three pregnant women (control n = 40, exercise n = 43) were included in the present quasi-experimental study. The exercise intervention consisted of a 60 min, 3 day/week throughout pregnancy from gestational week 17, supervised concurrent (aerobic + resistance) exercise program. A food frequency questionnaire and the MD Score (min–max: 0–50) were employed to assess dietary habits and the MD adherence during pregnancy, respectively. Postpartum body composition was measured with dual-energy X-ray absorptiometry, 6 weeks postpartum. The body mass index and the gynecoid fat mass at postpartum were lower in the exercise compared to the control group (p = 0.018 and p = 0.047, respectively). There was an interaction showing that the MD adherence during pregnancy positively moderated the effects of the exercise intervention on postpartum lean mass (p = 0.024), fat mass percentage (p = 0.092), android fat mass (p = 0.076), and android-to-gynecoid fat mass (p = 0.019). The Johnson–Neyman technique revealed that the effects of exercise were enhanced at a MD score of ~31 for lean mass, ~25 for fat mass, ~23 for android fat mass and ~29 for android-to-gynecoid fat mass. Our results suggest that a concurrent-exercise training plus an optimal MD adherence during pregnancy might be a useful strategy to promote a healthier body composition at the postpartum period.

This article evaluates the reliability and consistency of nutrition- and supplementation-related advice for pregnant women provided by ten selected health-related Internet portals. The portals were chosen based on their perceived reliability and prominence in Google searches, with representation from both English and Polish language sources. The evaluation criteria included the adherence of the presented information to official recommendations and its evidence-based character based on specific items representing dietary aspects important in pregnancy. While the overall reliability was deemed acceptable, significant variations existed both among the portals and specific evaluated items. Notably, HealthLine, Medline Plus, and NCEZ emerged as the most evidence-based, while WebMD and Medycyna Praktyczna were identified as less reliable. Despite a number of issues, the analysed portals remain valuable sources of nutritional information for pregnant women, offering user-friendly accessibility superior to alternatives such as social media on the one hand and scientific articles on the other. Improved consistency and attention to detail, especially in relation to vitamin intake and supplementation, would improve the overall quality of health portals. Full article
