“…In the most recently published study using primary collected data, Bastek and colleagues reported no significant association between neighborhood context and PTD in a cohort of 817 mostly AA women from Philadelphia. 19 Similarly, Phillips et al examined the association between an aggregate socioeconomic measure of neighborhood quality and spontaneous PTD, using data from the Black Women's Health Study and found no significant associations. 20 …”

Evidence suggests that neighborhood disadvantage predicts preterm delivery (PTD). However, the design of most existing studies precludes within-group analyses, which would allow the identification segments of the population at highest risk, as well as preventive factors. African Americans (AA) are disproportionately affected by PTD, are disproportionately concentrated in disadvantaged neighborhoods, and frequently use religious coping in response to chronic stressors. Our objective was to examine the association between neighborhood disadvantage and PTD, and whether religious coping moderated the associations, among postpartum AA women. Addresses from participants of the Life Influences on Fetal Environments Study (n=1387) were geocoded and linked to data from the American Community Survey. An index of neighborhood disadvantage was derived from a principal components analysis of the following variables: % below poverty, % unemployed, % receiving public assistance income, % college educated, % AA, % female-headed households, % owner occupied homes, median income, and median home value. Three domains of religious coping were assessed: organizational (church attendance), non-organizational (praying for self and asking others for prayer), and personal or subjective (experiences, perceptions, and sentiments about religion), and all were dichotomized as frequent/infrequent or satisfied/not satisfied. Preterm delivery was defined as birth before 37 completed weeks of gestation. Prevalence ratios and 95% confidence intervals were estimated with log binomial regression models. Neighborhood disadvantage did not predict PTD rates in the overall sample. However, there was evidence of moderation by asking others for prayer (P for asking for prayer X disadvantage index interaction term: 0.01). Among women who infrequently asked others for prayer, neighborhood disadvantage was positively associated with PTD rates (adjusted Prevalence ratio: 1.28, 95% Confidence Interval: 1.01, 1.63), and a null association was found for those who frequently asked others for prayer. No evidence of moderation by the other religious coping variables was present. Non-organizational religious coping may buffer against the adverse effects of neighborhood disadvantage on PTD rates, among urban AA women. Future research should examine the mechanisms of the reported relationships.

“…20 Unfortunately, despite of much work done in past and also being done currently, no consistency could yet be established regarding prevalence of preterm birth worldwide, as the range of the PTB prevalence has been reported to be as low as 1.52 21 to as high as 41.5%. 22 The difference in these statistics may be due to different designs, restricted venues, and limited or specific study objectives. In current meta-analysis we found one of the highest pooled prevalence of PTB i.e.…”

Objective: This study is designed to systematically review the prevalence of preterm birth from previously published studies of Pakistan and to find pooled prevalence from available local data. Methodology:Targeted literature was searched with specific key words such as "preterm birth, prematurity, prevalence and mortality in preterm birth in Pakistan". Studies with copyright and/or permission issues were excluded. A total of 300 studies were found initially that were somewhat related to the topic, after careful screening only 5 studies met inclusion criteria for current study. To test the null hypothesis for all studies evaluating effect Cochran's Q was used and P-values with a level of significance of 5%were considered significant. Results:The pooled prevalence of Preterm Birth was found to be 18.89% using fixed effect, 16.81% using random effect and 18.89% using fixed effect heterogeneity. I-squared for each effect model was > 75%. On applying Chi 2 test we obtained significant p-value i.e. p-value < 0.01. Conclusion: Through this meta-analysis we found one of the highest pooled prevalence of preterm birth in Pakistan. Reducing preterm birth can result in improvement of overall neonatal health and significantly reduce neonatal mortality in future.

“…Tackling these problems is another of the SDGs (Goal 11: sustainable cities and communities) . Neighborhoods and built environments have been assessed as measures of deprivation and racial isolation and observed to be associated with the risk of adverse birth outcomes, including preterm birth, though the evidence is not consistent . In a US‐based study, higher levels of racial isolation, measured as the probability that in a random encounter an African‐American resident would meet another African‐American resident within a given neighborhood, were found to be an independent risk factor for preterm birth (aOR, 1.27; 95% CI, 1.10‐1.46) .…”

Preterm birth continues to be a problem affecting low-, middle-, and high-income countries, with rates increasing in some areas despite ongoing efforts to reduce the incidence. This emphasizes the need for more effective interventions, particularly if we aim to achieve the broad health targets of the Sustainable Development Goals (SDGs) by 2030. The current focus on medically-oriented interventions such as reducing nonmedically-indicated induction of labor, cesarean birth, and multiple embryo transfers associated with assisted reproductive technologies, as well as the application of cervical cerclage and use of progesterone therapy, though important, are likely only partial solutions to the complex phenomenon of preterm birth. Preterm birth has multiple etiologies. The biologic mechanisms involved in preterm labor and how it may be triggered are not well understood. There is growing evidence to suggest some of these triggers may also be related to stress and environmental conditions. In this review, we focus on evidence concerning psychosocial (mind) and environmental factors (environment) as well as briefly review the evidence related to maternal and fetal factors (body) associated with the risk of preterm birth, with reference to some of the SDGs. We also assess emerging evidence regarding the interaction of the body, mind, and environment in relation to preterm birth, currently a gap in our knowledge, and how these interactions could impact clinical practice. Findings suggest that multidisciplinary expertise and approaches will be needed to develop effective interventions to address the complex etiologies of preterm birth, as opposed to single-risk-factor mitigation. Clinicians and researchers will play key roles in identifying many of these risk factors and shaping interventions that address this complex issue. Addressing the interlinkages between body, mind, and environment through the integration of research and clinical practice is critical to reducing the risk of preterm birth and contributing to the achievement of the SDGs.
