Impact of lifestyle factors on fracture risk in older patients with cardiovascular disease: a prospective cohort study of 26,335 individuals from 40 countries

Bidirectional association between cardiovascular disease and hip fracture: a systematic review and meta-analysis

BACKGROUND

The aim of this study was to comprehensively analyze the bidirectional association between cardiovascular disease (CVD) and hip fracture (HF).

METHODS

We searched PubMed, EMBASE, Web of Sciences, Cochrane Library, ScienceDirect and China National Knowledge Infrastructure for relevant studies. The Newcastle-Ottawa scale was used to evaluate the risk of bias. We conducted random effects model for meta-analysis and subgroup analysis of different ethnic groups. Sensitivity analysis and publication bias of this study were also evaluated. This study followed the PRISMA and MOOSE guidelines for systematic reviews and meta-analyses.

RESULTS

This research included 18 cohort studies and case-control studies with a total sample of 1,854,441 individuals. The results showed ischemic heart disease might increase the risk of HF (OR = 1.41, 95%CI[1.05, 1.89], I2 = 96%). Stroke might be a risk factor for HF (OR = 2.23, 95%[1.18, 4.19], I2 = 97%), and HF might likewise be a risk factor for Stroke ( OR = 2.22, 95% CI [1.81, 2.71], I2 = 78%). Heart failure might increase the risk of HF (OR = 2.89, 95%CI [1.22, 6.85], I2 = 91%), and HF might increase the risk of heart failure (OR = 2.74, 95%CI [1.27, 5.89], I2 = 92%). Hypertension might increase the risk of HF (OR = 1.55, 95%CI[1.34, 1.8], I2 = 87%), and HF might increase the risk of hypertension (OR = 3.75, 95%CI[3.3, 4.26], I2 = 98%). Cerebrovascular disease (OR = 1.96, 95%CI[1.61, 2.4], I2 = 79%) and diseases of arteries, arterioles, and capillaries (OR = 1.58, 95%CI[1.49, 1.68], I2 = 0%) might increase the risk of HF. HF might increase the risk of myocardial infarction (OR = 2, 95%CI[1.17, 3.41], I2 = 97%) and CVD-related death (OR = 1.78, 95%CI[1.05, 3.02], I2 = 50%). Subgroup analyses showed that among Asians IHD might not raise the risk of HF (OR = 1.33, 95% CI [1.00, 1.78], I2 = 95%). In caucasians, IHD might also not raise HF risk (OR = 1.52, 95%CI [0.64, 4.56], I2 = 95%).

CONCLUSIONS

This study supports possible bidirectional associations between CVD and HF, but more mechanistic studies of CVD and HF were warranted. However, high heterogeneity and potential confounding by unmeasured variables warrant cautious interpretation.

Alcohol Consumption and Risk of Fractures: A Systematic Review and Dose-Response Meta-Analysis of Prospective Cohort Studies

Alcohol consumption remains inconsistently correlated with fracture risk, and a dose-response meta-analysis for specific outcomes is lacking. The objective of this study was to quantitatively integrate the data on the relationship between alcohol consumption and fracture risk. Pertinent articles were identified in PubMed, Web of Science, and Embase databases up to 20 February 2022. Combined RRs and 95% CIs were estimated by random- or fixed-effects models. Restricted cubic splines were used to model linear or nonlinear relationships. Forty-four articles covering 6,069,770 participants and 205,284 cases of fracture were included. The combined RRs and 95% CIs for highest compared with lowest alcohol consumption were 1.26 (1.17-1.37), 1.24 (1.13-1.35), and 1.20 (1.03-1.40) for total, osteoporotic, and hip fractures, respectively. A linear positive relationship between alcohol consumption and total fracture risk was detected (Pnonlinearity = 0.057); the risk was correlated with a 6% increase (RR, 1.06; 95% CI: 1.02, 1.10) per 14 g/d increment of alcohol consumption. J-shaped relationships of alcohol consumption with risk of osteoporotic fractures (Pnonlinearity < 0.001) and hip fractures (Pnonlinearity < 0.001) were found. Alcohol consumption of 0 to 22 g/d was linked to a reduced risk of osteoporotic fractures and hip fractures. Our findings show that any level of alcohol consumption is a risk factor for total fractures. Moreover, this dose-response meta-analysis shows that an alcohol consumption level of 0 to 22 g/d is related to a reduction in the risk of osteoporotic and hip fractures. The protocol was registered in the International Prospective Register of Systematic Reviews (CRD42022320623).

A systematic review and meta-analysis of prospective cohort studies on the association between alcohol intake and risk of fracture

Previous studies on the association between alcohol intake and risk of fracture have reached conflicting findings. The aim of this systematic review and meta-analysis of prospective cohort studies was to summarize earlier studies on the association of alcohol intake with risk of fracture. A systematic search of PubMed, Scopus, and ISI Web of Science was conducted up to November 2020. Prospective cohort studies that had considered alcohol consumption as the exposure variable and fracture as the main outcome or as one of the outcome variables were included in this systematic review. Publications in which odds ratios (ORs), rate or risk ratios (RRs), or hazard ratios (HRs) and 95% confidence intervals (CIs) were reported, were included in the meta-analysis. In total, 40 prospective cohort studies including 5,084,303 participants and 170,916 subjects with fracture were included in this systematic review; of them 38 studies with a total sample size of 5,053,117 participants and 169,560 cases of fracture were included in the meta-analysis. Using a random-effects meta-analysis, we found a significant positive association between alcohol consumption and risk of total fractures (RR: 1.35; 95% CI: 1.01, 1.81) and any fractures (RR: 1.24; 95% CI: 1.11, 1.38). However, no significant association was observed between alcohol intake and risk of hip fractures (RR: 1.19; 95% CI: 0.96, 1.48), osteoporotic fractures (RR: 2.01; 95% CI: 0.76, 5.34), vertebral fractures (RR: 0.98; 95% CI: 0.68, 1.40), and wrist fractures (RR: 0.99; 95% CI: 0.85, 1.16). In conclusion, we found that alcohol consumption was positively associated with risk of total fractures and any fractures. However, we did not observe any significant association between alcohol consumption and risk of hip, osteoporotic, vertebral, and wrist fractures.

Recovery patterns over 4 years after distal radius fracture: Descriptive changes in fracture-specific pain/disability, fall risk factors, bone mineral density, and general health status

STUDY DESIGN

Descriptive/Longitudinal cohort.

INTRODUCTION

Distal radius fracture (DRF) is a common fall related fragility fracture that is known to be an early and independent predictor of secondary osteoporotic (OP) fractures. Changes in falls risk status, bone status and general health has not been evaluated prospectively in a population that has sustained a DRF.

PURPOSE OF THE STUDY

The purpose of our study was to describe the status of fracture-specific pain/disability, fall risk factors such as physical activity (PA) and fear of falling (FOF), bone mineral density (BMD) and general health status (HS) in people with a DRF and how these variables change over four years with respect to sex, age, incidence of secondary falls and secondary OP fractures.

METHODS

Patients (n = 94) self-reported their fracture-specific pain and disability (Patient-Rated Wrist Evaluation), PA (Rapid Assessment of Physical Activity), FOF (Modified Fall Efficacy Scale), HS (12-item Short Form Health Survey) and completed dual-energy X-ray absorptiometry scan based BMD assessment (lumbar spine and total hip) at baseline (1-2 weeks post-fracture), six months and four years after DRF. Descriptive statistics and general linear models were used to describe changes in recovery patterns over four years.

RESULTS

There was significant (p<0.001) improvement in fracture-specific pain/disability (60 points), FOF (1 point) and physical HS (11 points) between baseline and 4 year follow-up. There were no significant changes in PA and BMD. When stratified with respect to age, sex, presence of subsequent falls and OP fractures, there were no significant differences in fracture-specific pain/disability, PA, FOF, and BMD at baseline, six months or four years after DRF. The physical HS was significantly (p<0.05) less/poorer among those with secondary falls (lower by 2-6 points) and fractures (lower by 5-6 points) compared to those without. Similarly, mental HS was significantly (p<0.05) poorer among people with secondary falls (lower by 2-6 points) and in 50-64 year age group (lower by 3-5 points) than those without secondary falls and in 65-80 year age group, respectively.

CONCLUSION

Post DRF, the majority of the improvement in fracture-specific pain/disability, FOF and HS was completed at six months and very small changes were observed between the six month and four year follow-up.

Risk factors predicting subsequent falls and osteoporotic fractures at 4 years after distal radius fracture-a prospective cohort study

In a prospective cohort of 113 patients followed 4 years after distal radius fracture (DRF), 24% of patients experienced a subsequent fall and 19% experienced a subsequent fracture. People with poor balance, greater fracture-specific pain/disability, low bone density, and prior falls had nearly a three times higher risk of subsequent falls.

PURPOSE

To determine the extent to which modifiable risk factors alone or in combination with bone mineral density (BMD) and non-modifiable risk factors predict subsequent falls and osteoporotic (OP) fractures after distal radius fracture (DRF).

METHODS

We assessed a cohort of patients (n = 191; mean age = 62 ± 8 years; female = 88%) shortly after DRF (baseline) and again at 4 years to identify subsequent falls or OP fractures. Baseline predictors included age, sex, prior falls, and modifiable risk factors such as balance, muscle strength, physical activity, fear of falling, BMD, fracture-specific pain/disability, and general health status. Univariate, multivariate, and stepwise logistic regression analyses were conducted to compute odds ratio (OR) with 95% CI to determine the extent of association between the risk factors and outcomes.

RESULTS

Among the 113 patients, who completed 4-year follow-up, 24% reported ≥ 1 subsequent fall and 19% reported ≥ 1 subsequent fracture. Significant predictors of subsequent falls included poor balance (OR = 3.3), low total hip BMD (OR = 3.3), high patient-rated wrist evaluation (PRWE) score (OR = 3.0), and prior falls (OR = 3.4). When adjusted for BMD, age, and sex; only prior falls (OR = 4.1) remained a significant independent predictor of future falls. None of the modifiable or non-modifiable risk factors were significantly associated with subsequent fractures.

CONCLUSION

Prior falls (≥ 2) is an independent predictor of subsequent falls in patients with DRF. In clinical practice, screening of patients for prior falls, balance, fracture-specific pain/disability, and BMD may identify those who might be at risk of subsequent falls after their first DRF.
