Prevalence of Hypertensive Disorders of Pregnancy and Associated Birth Outcomes Among Adolescent Mothers at a Tertiary Hospital in Zambia: A Retrospective Cross-Sectional Study.
Article in International journal of hypertension, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbidity, yet data on their burden among adolescent mothers in Sub-Saharan Africa are limited. This study aimed to determine the prevalence of HDP and their association with birth outcomes among adolescent mothers at Livingstone University Teaching Hospital (LUTH) in Zambia. Methods: We conducted a retrospective cross-sectional study of 405 medical records of adolescent pregnancies (aged 10-19 years) at LUTH from January 2023 to December 2024. HDP was defined as systolic/diastolic blood pressure ≥ 140/90 mmHg after 20 weeks of gestation. Data were abstracted using REDCap and analyzed with StatCrunch. Univariable and multivariable logistic regression identified factors associated with HDP. Bivariate analyses examined associations with birth outcomes. Statistical significance was set at Results: The prevalence of HDP was 16.8% (68/405). In multivariable analysis, increasing age (AOR = 1.31 per year, 95% CI: 1.06-1.63, Conclusions: HDP affect nearly one in six adolescent mothers at a Zambian tertiary hospital and are strongly associated with adverse birth outcomes. Older age, prior hypertension, and family history of chronic hypertension are independent predictors. Enhanced antenatal risk assessment, including detailed personal and family history, age-stratified monitoring, and routine proteinuria screening, is urgently needed to improve maternal and neonatal outcomes in this high-risk population.
