“…Around half of them reported suffering from mild depression and anxiety, which is higher than the proportion reported in the Urban China study ( 9 ). These results might be related to the lower intake of fish or omega-3 polyunsaturated fatty acids during pregnancy and the postpartum period, as reported by Hamazaki et al ( 21 ).…”

BackgroundDuring the lockdown period, a substantial group of these women reported lifestyle changes.AimThe aim of the study is to characterize the dietary patterns, intake and the adherence to the United States Department of Agriculture (USDA) pregnancy guidelines before and during the COVID-19 pandemic in Eastern Mediterranean postartum women.MethodsAn internet-based cross-sectional survey was used to collect the data. The survey was carried out among 1,939 postpartum women from five countries from the Eastern Mediterranean region. Change in dietary intake from the five food groups and the adherence to USDA's daily recommendations were assessed.FindingsThere was a significant increase in the mean (SD) consumption of all the food groups, including bread, rice, and other cereals, fruits, vegetables, milk and milk products, white and red meat, and nuts during the pandemic. Around 84% of participants reported no/low adherence (0–2) to USDA guidelines, whereas only 15% reported moderate or high adherence (3–5) to the guidelines before the pandemic. However, there was an increase in the proportion of subjects reporting moderate/high adherence (22%) during the pandemic.Discussion and conclusionsA substantial proportion of our study participants reported a lower dietary intake than the recommended amounts, and low adherence to the five food groups. Reasonable and applicable actions should be taken to protect postpartum women and their children from the effects of low dietary intake, particularly during pandemics and lockdowns. More researches are needed to identify the modifiable factors which could improve the nutritional status of the postpartum women during the pandemic.

“…A meta‐analysis of the prevalence of depression (major depressive disorder and minor depressive disorder) during the first 3 and 6 months after delivery found that prevalence was as high as 12.8% during the first 3 months and remained high at roughly 10% during the first 6 months 2 . In recent studies of maternal populations representative of pregnant Japanese women, we found that the prevalence of PDS at 1 and 6 months was 13.8% and 11.6%, respectively 3,4 …”

Objective Women with postpartum depressive symptoms (PDS) are at higher risk of postpartum depression (PPD) and require further assessment. Emerging evidence indicates a relationship between the total cholesterol (TC) level of blood and PPD but the results are inconsistent. In this study, we investigated the possible association of change in serum TC levels during pregnancy with the risk of PDS in a Japanese population. Methods We analyzed complete data on questionnaire responses and serum lipid profiles of pregnant women from 12 datasets obtained from the Japan Environment and Children's Study (n = 61,585 to n = 72,406; 103,063 pregnancies in total). TC was measured at 3 time points—during early pregnancy, during mid‐late pregnancy, and after delivery—and we calculated changes in TC in 3 ways: by subtracting early pregnancy from mid‐late pregnancy, subtracting mid‐late pregnancy from delivery, and subtracting early pregnancy from delivery. These 6 factors were used as predictors to estimate the risk of PDS at 1 and 6 months after delivery. Results In multivariable logistic regression analysis, point serum cholesterol level did not predict PDS at any time point except for during mid‐late pregnancy in the second quintile, indicating an increased risk at 6 months. As for change in TC levels, subtracting mid‐late pregnancy from delivery and early pregnancy from delivery showed significant risk reduction for PDS at 1 month. A significant risk reduction was also found for subtracting early pregnancy from mid‐late pregnancy and early pregnancy from delivery at 6 months. Conclusions Increased cholesterol level during pregnancy is associated with reduced risk of PDS.

“…The third finding is consistent with previous results concerning the association between maternal omega-3 intake and postpartum depression (Hamazaki et al ., 2018 , 2020 ). Such a U-shape association was also observed in those studies, whether significant or not, even though the exposure variable was the intake of omega-3 PUFAs by pregnant women rather than by male partners.…”

Aims Intake of omega-3 polyunsaturated fatty acids (PUFAs) has favourable effects on reducing aggressive and violent behaviours, but its association with perpetration of intimate partner violence (IPV) is not known. We aimed to determine the association between male intake of omega-3 PUFAs and risk of IPV perpetration. Methods Participants were male–female pairs in the Japan Environment and Children's Study, in which first pregnant women and then their partners were enrolled (analytic sample: n = 48 065). Male intake of omega-3 PUFAs during the past year (preconception to mid/late pregnancy) was determined using a food frequency questionnaire. IPV (physical violence and emotional abuse) during pregnancy was measured using a self-reported questionnaire completed by pregnant women in mid/late pregnancy. Generalised additive mixed-model analysis was used to examine the non-linear association between energy-adjusted male omega-3 PUFA intake and the adjusted prevalence of male IPV perpetration. Results A sharply decreasing regression curve was plotted for physical violence, with prevalence starting at 1.35% at the lowest intake level and decreasing to a minimum value of 0.76% at intake of 2.20 g/day (71.7th percentile). However, prevalence largely remained flat from there onward, with the upper limit of the error range not reaching the initial lower limit of the error range until intake exceeded 5.21 g/day (99.77th percentile). For emotional abuse, on the other hand, there was a distorted U- or V-shaped regression curve that rose slightly after reaching a minimum. The prevalence declined from 17.69% initially, reached a minimum at 12.44% at 2.13 g/day (68.3th percentile), and then rose slightly. The lower limit of the error range reached the minimum upper limit at 4.17 g/day (99.1th percentile), and the upper limit finally reached the maximum lower limit value at 4.56 g/day (99.5th percentile). Conclusions In this nationwide birth cohort study, higher male intake of omega-3 PUFAs was associated with lower risk of physical violence and emotional abuse perpetration except for extremely high intake. Our results indicate the potential applicability of omega-3 PUFAs in reducing aggressive and violent behaviours in IPV. Trial registration: UMIN000030786.
