Individual and collective contribution of antenatal psychosocial distress conditions and preterm birth in Pakistani women

Abstract

Background We determined whether dimensions of psychosocial distress during pregnancy individually and collectively predicted preterm birth (PTB) in Pakistani women as it may be misleading to extrapolate results from literature predominantly conducted in high-income countries. Methods This cohort study included 1603 women recruited from four Aga Khan Hospital for Women and Children in Sindh, Pakistan. The primary binary outcome of PTB (i.e., livebirth before 37 completed weeks’ gestation) was regressed on self-reported symptoms of anxiety (Pregnancy-Related Anxiety (PRA) Scale and Spielberger State-Trait Anxiety Inventory Form Y-1), depression (Edinburgh Perinatal Depression Scale (EPDS)), and covariates such as chronic stress (Perceived Stress Scale) assessed with standardized question and scales with established language equivalency (Sindhi and Urdu). Results All 1603 births occurred between 24 and 43 completed weeks’ gestation. PRA was a stronger predictor of PTB than other types of antenatal psychosocial distress conditions. Chronic stress had no effect on the strength of association between PRA and PTB and a slight but non-significant effect on depression. A planned pregnancy significantly lowered risk of PTB among women who experienced PRA. Aggregate antenatal psychosocial distress did not improve model prediction over PRA. Conclusions Like studies in high-income countries, PRA became a strong predictor of PTB when considering interactive effects of whether the current pregnancy was planned. Women’s resilience and abilities to make sexual and reproductive health decisions are important to integrate in future research. Findings should be generalized with caution as socio-cultural context is a likely effect modifier. We did not consider protective/strength-oriented factors, such as resilience among women.

Prevalence of Perinatal Anxiety and Related Disorders in Low- and Middle-Income Countries

“…Given that generalized anxiety disorder was reported across 184 studies, we were able to further interrogate the prevalence of this disorder across important subgroups (Figure 3). While investigating generalized anxiety by country income status, we found a higher prevalence among studies performed in lower-middle–income countries (27.6%; 95% CI, 21.6%-33.9%; 59 studies; n = 25 109) compared with low-income countries (24.0%; 95% CI, 15.3%-33.8%; 11 studies; n = 4961). Upper-middle–income countries had the lowest prevalence (19.1%; 95% CI, 16.0%-22.4%; 110 studies; n = 138 496).…”

“…Generalized anxiety disorder (including anxiety not specified) was the most commonly reported anxiety disorder, examined by 184 of 203 studies (90.6%) . The pooled point prevalence for generalized anxiety disorder was 22.2% (95% CI, 19.4%-25.0%; n = 173 553).…”

“…Our search identified 10 617 studies; 1231 full texts were reviewed, and of these, 203 studies were included (Figure 1; eTable 2 in Supplement 1). Cumulatively, outcomes were reported for 212 318 perinatal women (from conception to 12 months post birth) from 33 LMICs. The prevalence estimates of 6 anxiety and related disorders were reported: generalized anxiety disorder, social anxiety disorder, posttraumatic stress disorder, obsessive-compulsive disorder, panic disorder, and adjustment disorder.…”

“…The majority of studies reported the prevalence of generalized anxiety antenatally (150 [81.5%]). Among these, the pooled point prevalence was 23.9% (95% CI, 20.5%-27.4%; n = 149 485).…”

“…Next, we assessed the prevalence of generalized anxiety by method of assessment. Screening tools were used in 153 studies (17 different questionnaires), and 30 studies used a structured or semistructured diagnostic interview (8 types). One study used both .…”
