“…Our analysis identified specific serious life events that were associated with PTB, and we also showed a linear relationship for the association of PTB with number of serious events experienced during pregnancy. Our findings are consistent with the results of studies that evaluated serious life events with PTB10,25 and differ from studies that found significant associations only when analyzing specific timing of exposure to an event during pregnancy11,14,26 and those where the associations did not reach significance 7,16,27,28. Studies identifying serious life events have typically been carried out in developed countries or among minority populations in the US.…”

“…Studies in Europe and South America have shown that the significance and strength of associations of stressful events with PTB varied based on the timing of exposure 11–14. Some investigators have found that pregnancy-related stress was a better predictor of PTB than general stress,15 while another study that compiled a stress score based on life events and a general health questionnaire found no association, but suggested that evaluating specific types of life events could be important 16. An accumulating body of evidence has shown that the prevalence of PTB is increasing globally, and this prevalence is expected to increase primarily in low and middle income countries, such as Peru 17.…”

BackgroundThe purpose of this study was to examine the risk of preterm birth (PTB) in relation to serious life events experienced during pregnancy in Peruvian women.MethodsThis case-control study included 479 PTB cases and 480 term controls. In-person interviews asked information regarding sociodemographics, medical and reproductive histories, and serious life events experienced during pregnancy. Multivariate logistic regression procedures were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs).ResultsCompared with women who did not experience a serious life event during pregnancy, those who experienced the following life events had a more than two-fold increased odds of PTB: death of first-degree relative (adjusted OR 2.10; 95% CI 1.38–3.20), divorce or separation (adjusted OR 2.09; 95% CI 1.10–4.00), financial troubles (adjusted OR 2.70; 95% CI 1.85–3.94), or serious fight with partner (adjusted OR 2.40; 95% CI 1.78–3.17). Women who experienced any serious life events during pregnancy had higher odds (adjusted OR 2.29; 95% CI 1.65–3.18) of suffering spontaneous preterm labor and preterm premature rupture of membranes (adjusted OR 2.19; 95% CI 1.56–3.08), compared with women who did not experience any such events. Associations of similar directions and extent were observed for severity of PTB (ie, very, moderate, or late PTB). The magnitude of the associations increased as increased frequency of serious life events (Ptrend <0.001).ConclusionExperiencing serious life events during pregnancy was associated with increased odds of PTB among Peruvian women. Interventions aimed at assisting women experiencing serious life events may reduce the risk of PTB. Future studies should include objective measures of stress and stress response to understand better the biological underpinnings of these associations.

“…Investigations in the United States (Suri et al, 2007), in Norway (Berle et al, 2005), and in Sweden (Andersson et al, 2004) did not confirm associations between anxiety disorders or depression during pregnancy and LBW in infants. Similar conclusions were drawn from investigations in Sri Lanka, where psychosocial stress was not found to be related to LBW (Abeysena et al, 2010).…”

The aim of this study was to investigate associations of birth weight with sociodemographic variables, domestic violence, ways of coping, social support, and general mental health of Iranian mothers. Six hundred mothers aged 15 to 29 years participated between June 2009 and November 2010. t-Test, analysis of variance, Spearman's correlation, and multiple regression were used. The results showed that there was no significant association between birth weight and general mental health of the mothers. Prenatal care visits, the mothers' history of having children with low birth weight (LBW), and weight gain during pregnancy were significantly associated with birth weight. The women who reported physical abuse during pregnancy had infants with lower birth weight. Satisfaction with social support and use of positive reappraisal were significantly associated with higher birth weight. In conclusion, a high quality of prenatal care and screening of pregnant women are recommended. Social environments good enough during pregnancy have protective effects against LBW.

“…Several studies suggested that stress during the third trimester is the most harmful [3,9,19], while others have implicated stress in the first [20] and second trimesters [4,8] in the risk of preterm birth and LBW. Interestingly, there are a number of contradictory studies on this topic and it is clearly a point of contention despite being studied for over 3 decades [9,21].…”

“…Stress from major life events and other forms of emotional stress have been implicated in increasing the risk of preterm births [2][3][4] and low-birthweight (LBW) infants [1]. It is believed that armed conflicts aggravate social factors that increase maternal psychosocial stressors [5], and this has been significantly associated with preterm delivery [2,[6][7][8][9].…”

Stressful life events experienced by pregnant women may lead to adverse obstetric outcomes. This study in Benghazi compared the rates of preterm, low-birth-weight and caesarean-section births at Al-Jamhouria hospital in the months before and during the armed conflict in Libya in 2011. Data were collected on all women admitted to the delivery ward during February to May 2011 (the months of the most active fighting in the city) (n = 7096), and October to December 2010 (the months immediately before the war) (n = 5935). Compared with the preceding months there was a significant rise during the conflict in the rate of deliveries involving preterm (3.6% versus 2.5%) and low-birth-weight (10.1% versus 8.5%) infants and caesarean sections (26.9% versus 25.3%). Psychosocial stress may have been a factor (among others) in an increase in negative pregnancy outcomes, and obstetric hospitals should be aware of these issues in times of war. 1Faculty of Medicine, Libyan International Medical University, Benghazi, Libya (Correspondence to Z. Bodalal: zuhir.bodalal@limu.edu.ly . Par rapport aux mois précédents, une augmentation importante du taux d'accouchements impliquant une prématurité (3,6 % contre 2,5 %) et un faible poids de naissance (10,1 % contre 8,5 %) ainsi que des césariennes (26,9 % contre 25,3 %) a été observée pendant le conflit. Le stress psychosocial peut avoir été un facteur (entre autres) dans l'augmentation des issues négatives de la grossesse, et les établissements obstétricaux devraient être informés de ces problèmes en temps de guerre.

Effect of psychosocial stress and physical activity on preterm birth: A cohort study

Abstract: Standing equal to or less than 2.5 h/day during the early trimesters was a risk factor for PTB among uncomplicated pregnancies. Further studies are recommended to assess the trimester-specific effect of psychosocial stress on PTB.
