    A Proportional Hazard model to establish factors that are significant in child survival.
    (IOSR, 2014) Musizvingoza, R.; Mwembe, D.; Nyamugure, P.
    This study addresses important issues affecting under-five mortality in Zimbabwe. The objective of this research is to establish factors that are significantly impacting on child survival and to determine the survival rate of children under the age of five years. Cox regression and Kaplan-Meier estimator were used for data analysis. Child survival was significantly influenced by two predictor variables, breastfeeding and immunisation status (p< 0.05). The Hazard ratios for variable breastfeeding and immunisation are 2.806 and 4.778 respectively. The survival functions for the children indicate a high survival rate especially in children who are well breastfed and those who are fully immunised. This study supports health policy interventions that enhance child survival. Immunisation and breastfeeding should be encouraged among mothers to enhance child survival.

    May Measurement Month 2021: an analysis of blood pressure screening results from Zimbabwe
    (2024) Gwini, R.; Beaney, T.; Kerr, G.; Poulter, N.R.; Mwembe, D.; Chifamba, J.
    The May Measurement Month 2021 campaign in Zimbabwe was aimed at assessing the frequency of hypertension and improving awareness among the population of the sequelae of elevated blood pressure (BP). Participants aged 18 years and above were recruited at outdoor booths to fill out a questionnaire and provide three BP measurements with 1-min intervals. Of the 2094 participants, over one-third (37.3%) were hypertensive, half of hypertensives (49.7%) were aware they had elevated pressure, and less than half (45.0%) of the hypertensive patients were on antihypertensive medications. Increasing age was directly proportional to hypertension with a large leap from 9.5 to 27.7% between the 18–29 and 30–39 age groups. Hypertension remains a major public health challenge in Zimbabwe. Improving access to preventive health screening services as well as treatment facilities is essential to early detect and control hypertension.

    The prevalence of and risk factors for stillbirths in women with severe preeclampsia in a high-burden setting at Mpilo Central Hospital, Bulawayo, Zimbabwe
    (De Gruyter, 2022) Ngwenya, S.; Jones, B.; Mwembe, D.; Nare, H.; Heazell, A.E.P.
    Stillbirth remains a global public health issue; in low-resource settings stillbirth rates remain high (>12 per 1,000 births target of Every Newborn Action Plan). Preeclampsia is major risk factor for stillbirths. This study aimed to determine the prevalence and risk factors for stillbirth amongst women with severe preeclampsia at Mpilo Central Hospital. A retrospective cross-sectional study was conducted of women with severe preeclampsia from 01/01/2016 to 31/12/2018 at Mpilo Central Hospital, Bulawayo, Zimbabwe. Multivariable logistic regression was used to determine risk factors that were independently associated with stillbirths. Of 469 women that met the inclusion criteria, 46 had a stillbirth giving a stillbirth prevalence of 9.8%. The risk factors for stillbirths in women with severe preeclampsia were: unbooked status (adjusted odds ratio (aOR) 3.01, 95% (confidence interval) CI 2.20–9.10), frontal headaches (aOR 2.33, 95% CI 0.14–5.78), vaginal bleeding with abdominal pain (aOR 4.71, 95% CI 1.12–19.94), diastolic blood pressure ≥150 mmHg (aOR 15.04, 95% CI 1.78–126.79), platelet count 0–49 × 109/L (aOR 2.80, 95% CI 1.26–6.21), platelet count 50–99 × 109/L (aOR 2.48, 95% CI 0.99–6.18), antepartum haemorrhage (aOR 12.71, 95% CI 4.15–38.96), haemolysis elevated liver enzymes syndrome (HELLP) (aOR 6.02, 95% CI 2.22–16.33) and fetal sex (aOR 2.75, 95% CI 1.37–5.53). Women with severe preeclampsia are at significantly increased risk of stillbirth. This study has identified risk factors for stillbirth in this high-risk population; which we hope could be used by clinicians to reduce the burden of stillbirths in women with severe preeclampsia.
