Impact of interpregnancy intervals on perinatal and neonatal outcomes in a multiethnic Pakistani population.

BACKGROUND: Short birth intervals (SBIs) and long birth intervals (LBIs) have been shown to have serious implications for health of both mothers and their children. This study was aimed to investigate the determinants and reproductive outcome of SBI and LBI in a multiethnic Pakistani population. METHODS: In a cross-sectional prospective study design, 2798 women admitted in a tertiary-care hospital in Islamabad for delivery were recruited and data on second or higher birth order deliveries were collected. Birth intervals were defined as short (<24 months) and long (>36 months). The reproductive outcome was defined in terms of perinatal and neonatal mortalities, and neonatal complications. Univariate and multivariate logistic regression analyses were performed. RESULTS: Pregnancies with SBI and LBI were observed in 20% and 24% of 2798 women, respectively. Women with SBI had increased odds of perinatal death [adjusted odd ratio (AOR): 1.50] and neonatal death (AOR: 1.47) as compared to women with optimal birth intervals, while women with LBI had slightly lower odds of perinatal deaths (AOR: 0.96), but increased odds of neonatal deaths (AOR: 1.12). Further, the pregnancies with both SBI and LBI were associated with increased odds of short body length, low birth weight, small head circumference and low APGAR score. CONCLUSION: Nearly half of all pregnancies do not have optimal birth spacing albeit there is wide heterogeneity in the distribution of BI in various Pakistani ethnicities. Pregnancies with SBI and LBI had high risk of adverse reproductive outcome. Intervention programs for maternal and child health need to emphasize optimal birth spacing.

Birth interval (BI) or interpregnancy interval is the length of time between a birth and conception of the next pregnancy. Short birth intervals (SBIs) as well as long birth intervals (LBIs) have been shown to have serious implications for health of both mothers and their children. WHO recommendation for optimal spacing between 3 and 5 years. In this study, we aimed to investigate the effect of SBI and LBI on pregnancy outcome in the Pakistani population. A total of 2798 pregnant women admitted in a tertiary-care hospital in Islamabad for delivery were recruited and data on BI and pregnancy outcomes, i.e. perinatal and neonatal mortalities, and neonatal complications, were obtained. Results revealed that pregnancies with SBI and LBI were 20% and 24% of the total pregnancies, respectively. Women with SBI had higher likelihood of perinatal and neonatal death as compared to women with optimal birth intervals. Similarly, the women with LBI had higher likelihood of neonatal deaths. Furthermore, the pregnancies with both SBI and LBI were associated neonatal complications like short body length, low birth weight, small head circumference and low APGAR score. In conclusion, nearly half of all pregnancies do not have optimal birth spacing. Intervention programs for maternal and child health need to emphasize optimal birth spacing.

Prevalence-pattern and risk factors of Cesarean section in a multiethnic cohort.

OBJECTIVE: This study was aimed to elucidate the prevalence-pattern and determinant of cesarean section (CS) in a multiethnic cohort from Pakistan. METHODS: Through a cross-sectional study design, women delivering at a tertiary care center were recruited during 2013-2017. Data on socio-demographic variables, obstetric complications and birth outcome were obtained. Descriptive statistics, bivariate and multivariate logistic regression analyses were performed. RESULTS: A total of 5,275 pregnant women were recruited and 43% of the deliveries underwent CS. Odds of CS were significantly higher in subjects originating from Azad JammuKashmir and Sindh regions, speaking Potohari and Pahari languages, women in advance ages, and those who were housewives. CS had significantly lower odds of prenatal mortality but increased odds of postnatal mortality. Obstetric factors that appeared to be significant predictors of CS were multiparity, breech position, fetal distress, oligohydroamniosis, preeclampsia, and previous scar. CONCLUSION: This study revealed high variability in CS in various socio-demographic strata of study population. The obstetric complications highlighted in this study may be reduced by proper perinatal counseling and pregnancy monitoring and should be the focus of intervention programs as suggested in the Millennium Development Goals.

Talipes equinovarus or Clubfoot: A review of study approaches, management and trends in Pakistan.

This paper aims to assess the status of scientific literature on talipes equinovarus (TEV) published from Pakistan, to get an insight into the trend in knowledge over the years, and to highlight study gaps in this area. A detailed review of published literature was conducted from November 2019 to January 2020. 'Talipes/congenital talipes', 'clubfoot/congenital clubfoot', 'talipes equinovarus /congenital talipes equinovarus' AND 'Pakistan' were used as key terms. Different search engines, PubMed, PakMediNet, ScienceDirect, Embase and Google Scholar were utilized to retrieve articles. A total of 63 articles were retrieved. The hotspot of TEV research in Pakistan has been its treatment and management. Over the years, treatment trend has shifted from operative to conservative; Ponseti method is predominantly employed. Hospital-based studies focusing on pediatric patients are common while population-based studies are devoid. In majority of cohorts, there is preponderance of male patients, idiopathic and unilateral cases. There is, however, scarcity of basic research on the prevalence, etiology, risk factors, clinical heterogeneity, associated anomalies, genetics, and molecular diagnostics of TEV. In conclusion, prudent scientific evidence is required for any policy-making and relevant public health action. Hence, large scale population-based studies are required for a broader overview and understanding the clinical spectrum of TEV.
