Development of a stress scale for pregnant women in the South Asian context: the A-Z Stress Scale

Stress in pregnancy can lead to low-birth-weight and preterm babies and to psychological consequences such as anxiety and depression during pregnancy and the puerperium. Previous scales to measure stress contain items that overlap with the symptoms of pregnancy. A stress scale was developed based on in-depth interviews with pregnant women in Pakistan. Construct validity, test-retest reliability and inter-rater reliability were carried out. Cronbach alpha was 0.82 for the 30 short-listed items, with item-total correlations of 0.2-0.8. Multidimensional scaling determined 2 dimensions: socioenvironmental hassles and chronic illnesses. This was the first scale developed for pregnant women based on stressors in a developing country in South Asia

Maternal risk factors associated with low birth weight in Karachi: a case-control study

To evaluate maternal risk factors associated with low birth weight [LBW] among women aged 15-35 years, we carried out a hospital-based, case-control study on 262 cases [mothers of neonates weighing 2.5 kg]. Odds of delivering a low-birth-weight baby decreased with increase in maternal haemoglobin [odds ratio [OR]: 0.701; 95% confidence interval [CI]: 0.62-0.79]. Odds were greater among mothers not using iron supplements during pregnancy [OR: 2.88; 95% CI: 1.83-4.54]. Mothers of LBW babies had lower haemoglobin levels before delivery
