Hypertension and frailty: a systematic review and meta-analysis.

ABSTRACT:

Objective

To review the association between hypertension and frailty in observational studies.

Design

A systematic review of the PubMed, Web of Science and Embase databases was performed. A meta-analysis was performed if at least three studies used the same definition of frailty and a dichotomous definition of hypertension.

Setting, participants and measures

Studies providing information on the association between frailty and hypertension in adult persons, regardless of the study setting, study design or definition of hypertension and frailty were included.

Results

Among the initial 964 articles identified, 27 were included in the review. Four longitudinal studies examined the incidence of frailty according to baseline hypertension status, providing conflicting results. Twenty-three studies assessed the cross-sectional association between frailty and hypertension: 13 of them reported a significantly higher prevalence of frailty in hypertensive participants and 10 found no significant association. The pooled prevalence of hypertension in frail individuals was 72% (95% CI 66% to 79%) and the pooled prevalence of frailty in individuals with hypertension was 14% (95% CI 12% to 17%). Five studies, including a total of 7656 participants, reported estimates for the association between frailty and hypertension (pooled OR 1.33; 95%?CI 0.94 to 1.89).

Conclusions

Frailty is common in persons with hypertension. Given the possible influence of frailty on the risk-benefit ratio of treatment for hypertension and its high prevalence, it is important to assess the presence of this condition in persons with hypertension.

Project description:ObjectiveChronological age alone does not adequately reflect the difference in health status of a patient with hypertension. Frailty is closely associated with biological age, and its assessment is clinically useful in addressing the heterogeneity of health status. The purpose of our study is to comprehensively examine the predictive value of frailty for negative health outcomes in hypertensive patients through a systematic review and meta-analysis.MethodsMultiple English and Chinese databases were searched from inception to 04.11.2020. All cross-sectional and longitudinal studies that examined the association between frailty and relevant clinical outcomes among hypertensive patients were included. The NOS was used to assess the risk of bias of studies included in the analysis. Hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were pooled for outcomes associated with frailty.ResultsSix longitudinal studies and one cross-sectional study involving 17403 patients with hypertension were included in the meta-analysis. The risk of bias of all included studies was rated as low or moderate. The pooled HR of frailty related to mortality was 2.45 (95% CI: 2.08-2.88). The pooled HR of prefrailty and frailty-related injurious falls was 1.07 (95% CI: 0.83-1.37) and 1.89 (95% CI: 1.56-2.27), respectively. The pooled HR of prefrailty and frailty-related hospitalization was 1.54 (95% CI: 1.38-1.71) and 1.94 (95% CI: 1.17-3.24), respectively.ConclusionsThis systematic review suggests that frailty was a strong predictor of mortality, hospitalization, and injurious falls among patients with hypertension. Our findings indicate that assessment of frailty in patients with hypertension to guide their management may be necessary in clinical setting. However, our finding was based on very limited amount studies; thus, future studies are required to further validate the role of frailty in prediction of negative health outcomes in hypertensive patients as well as pay more attention to the following knowledge gaps: (1) the association between frailty and hypertension-related outcomes, (2) the significance of the association between different frailty models and relevant clinical outcomes, and (3) the predictive value of prefrailty for the negative health outcomes in people with hypertension.

Project description:ObjectiveTo provide an accurate assessment of complications of pregnancy in women with chronic hypertension, including comparison with population pregnancy data (US) to inform pre-pregnancy and antenatal management strategies.DesignSystematic review and meta-analysis.Data sourcesEmbase, Medline, and Web of Science were searched without language restrictions, from first publication until June 2013; the bibliographies of relevant articles and reviews were hand searched for additional reports.Study selectionStudies involving pregnant women with chronic hypertension, including retrospective and prospective cohorts, population studies, and appropriate arms of randomised controlled trials, were included.Data extractionPooled incidence for each pregnancy outcome was reported and, for US studies, compared with US general population incidence from the National Vital Statistics Report (2006).Results55 eligible studies were identified, encompassing 795,221 pregnancies. Women with chronic hypertension had high pooled incidences of superimposed pre-eclampsia (25.9%, 95% confidence interval 21.0% to 31.5 %), caesarean section (41.4%, 35.5% to 47.7%), preterm delivery <37 weeks' gestation (28.1% (22.6 to 34.4%), birth weight <2500 g (16.9%, 13.1% to 21.5%), neonatal unit admission (20.5%, 15.7% to 26.4%), and perinatal death (4.0%, 2.9% to 5.4%). However, considerable heterogeneity existed in the reported incidence of all outcomes (τ(2)=0.286-0.766), with a substantial range of incidences in individual studies around these averages; additional meta-regression did not identify any influential demographic factors. The incidences (the meta-analysis average from US studies) of adverse outcomes in women with chronic hypertension were compared with women from the US national population dataset and showed higher risks in those with chronic hypertension: relative risks were 7.7 (95% confidence interval 5.7 to 10.1) for superimposed pre-eclampsia compared with pre-eclampsia, 1.3 (1.1 to 1.5) for caesarean section, 2.7 (1.9 to 3.6) for preterm delivery <37 weeks' gestation, 2.7 (1.9 to 3.8) for birth weight <2500 g, 3.2 (2.2 to 4.4) for neonatal unit admission, and 4.2 (2.7 to 6.5) for perinatal death.ConclusionsThis systematic review, reporting meta-analysed data from studies of pregnant women with chronic hypertension, shows that adverse outcomes of pregnancy are common and emphasises a need for heightened antenatal surveillance. A consistent strategy to study women with chronic hypertension is needed, as previous study designs have been diverse. These findings should inform counselling and contribute to optimisation of maternal health, drug treatment, and pre-pregnancy management in women affected by chronic hypertension.

Project description:BackgroundThe burden of cardiovascular disease (CVD) and hypertension is rapidly increasing in low- and middle-income countries. This is evident not only in adults, but also in children. Recent estimates of prevalence in children are lacking, particularly in Africa. As such, we conducted a systematic review and meta-analysis to provide updated estimates of paediatric hypertension in Africa.MethodsWe searched PubMed and EBSCO to identify articles published from January 2017 to November 2020. Studies were assessed for quality. We combined results for meta-analyses using a random effects model (Freeman-Tukey arcsine transformation). Heterogeneity was quantified using the I2 statistic.FindingsIn the narrative synthesis of 53 studies, publication bias was low for 28, moderate for 24, and high for one study. Hypertension prevalence ranged substantially (0·2%-38·9%). Meta-analysis included 41 studies resulting in data on 52918 participants aged 3 to 19 years from ten countries. The pooled prevalence for hypertension (systolic/diastolic BP≥95th percentile) was 7·45% (95%CI 5·30-9·92, I2=98.96%), elevated blood pressure (BP, systolic/diastolic BP≥90th percentile and <95th percentile) 11·38% (95%CI 7·94-15·33, I2=98.97%) and combined hypertension/elevated BP 21·74% (95%CI 15·5-28·69, I2=99.48%). Participants categorized as overweight/with obesity had a higher prevalence of hypertension (18·5% [95%CI 10·2-28·5]) than those categorized as underweight/normal (1·0% [95%CI 0·1-2·6], 4·8% [95%CI 2·9-7·1], p<0·001). There were significant differences in hypertension prevalence when comparing BP measurement methods and classification guidelines.InterpretationCompared to a previous systematic review conducted in 2017, this study suggests a continued increase in prevalence of paediatric hypertension in Africa, and highlights the potential role of increasing overweight/obesity.FundingThis research was funded in part by the Wellcome Trust [Grant number:214082/Z/18/Z].
