Smoking and fracture risk in men: a meta-analysis of cohort studies, using both frequentist and Bayesian approaches. Sci Rep 2022; 12:9270. [PMID: 35661791 PMCID: PMC9166727 DOI: 10.1038/s41598-022-13356-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 05/16/2022] [Indexed: 11/15/2022] Open
Abstract
Past studies indicate that men are more likely to smoke and be at higher risk of smoking-related conditions than women. Our research aimed, through meta-analysis, to assess the association between smoking and fracture risk in men. The following databases were searched, including MEDLINE, EMBASE, Scopus, PsycINFO, ISI Web of Science, Google Scholar, WorldCat, and Open Grey, for identifying related studies. A random-effects model was used to pool the confounder-adjusted relative risk (R.R.). Frequentist and Bayesian hierarchical random-effects models were used for the analysis. The heterogeneity and publication bias were evaluated in this study. Twenty-seven studies met the inclusion criteria. Overall, smoking is associated with a significantly increased risk of fracture in both the frequentist approach (R.R., 1.37; 95% confidence interval: 1.22, 1.53) and the Bayesian approach (R.R., 1.36; 95% credible interval: 1.22, 1.54). Significant heterogeneity was observed in the meta-analysis (Higgin's I2 = 83%) and Cochran's Q statistic (p < 0.01). A significant association was also observed in multiple pre-specified sensitivity and subgroup analyses. Similar results were observed in the group containing a large sample size (≥ 10,000 participants), and the group has a small sample size (< 10,000 participants); the pooled R.R was 1.23 (95% confidence interval, 1.07–1.41) and 1.56 (95% confidence interval, 1.37–1.78), respectively. With the Bayesian method, the effect size was 1.23 (95% credible interval, 1.05, 1.45) for the large sample size group and 1.57 (95% credible interval, 1.35, 1.82) for the small sample size group. Smoking is associated with a significant increase in fracture risk for men. Thus, smoking cessation would also greatly reduce fracture risk in all smokers, particularly in men.

Abstract
INTRODUCTION Among the various hip fracture predictors explored to date, modifiable risk factors warrant special consideration, since they present promising targets for preventative measures. This systematic review and meta-analysis aims to assess various modifiable risk factors. MATERIAL AND METHODS We searched four online databases in September 2017. We included studies that reported on modifiable lifestyle risk factors for sustaining fragility hip fractures. The quality of the included studies was assessed using the Newcastle-Ottawa Scale (NOS). The inclusion criteria consisted of (1) adult patients with osteoporotic hip fracture, (2) original study, (3) availability of full text articles in English, and (4) report of a modifiable lifestyle risk factor. RESULTS Thirty-five studies, containing 1,508,366 subjects in total, were included in this study. The modifiable risk factors that were significantly associated with an increased risk of hip fracture were the following: weight < 58 kg (128 lbs) (pooled OR 4.01, 95% CI 1.62-9.90), underweight body mass index (BMI) (< 18.5) (pooled OR 2.83, 95% CI 1.82-4.39), consumption of ≥ 3 cups of coffee daily (pooled OR 2.27, 95% CI 1.04-4.97), inactivity (pooled OR 2.14, 95% CI 1.21-3.77), weight loss (pooled OR 1.88, 95% CI 1.32-2.68), consumption of ≥ 27 g (approx. > 2 standard drinks) alcohol per day (pooled OR 1.54, 95% CI 1.12-2.13), and being a current smoker (pooled OR 1.50, 95% CI 1.22-1.85). Conversely, two factors were significantly associated with a decreased risk of hip fracture: obese BMI (> 30) (pooled OR 0.58, 95% CI 0.34-0.99) and habitual tea drinking (pooled OR 0.72, 95% CI 0.66-0.80). CONCLUSION Modifiable factors may be utilized clinically to provide more effective lifestyle interventions for at risk populations. We found that low weight and underweight BMI carried the highest risk, followed by high coffee consumption, inactivity, weight loss, and high daily alcohol consumption.

Abstract
AIMS To evaluate the effects of an intensified multifactorial intervention and patient characteristics on the incidence of fractures comorbid with type 2 diabetes. METHODS Fracture events were identified and analyzed among adverse events reported in the J-DOIT3 study, a multicenter, open-label, randomized, parallel-group trial that was conducted in Japan, in which patients with type 2 diabetes were randomly assigned to receive conventional therapy for glucose, blood pressure, and lipids (targets: HbA1c < 6.9%, blood pressure <130/80 mm Hg, LDL-cholesterol <120mg/dL) or intensive therapy (HbA1c < 6.2%, blood pressure <120/75 mm Hg, LDL-cholesterol <80mg/dL) (ClinicalTrials.gov registration no. NCT00300976). RESULTS The cumulative incidence of fractures did not differ between those receiving conventional therapy and those receiving intensive therapy (hazard ratio (HR) 1.15; 95% CI, 0.91-1.47; P = 0.241). Among the potential risk factors, only history of smoking at baseline was significantly associated with the incidence of fractures in men (HR 1.96; 95% CI, 1.04-3.07; P = 0.038). In contrast, the incidence of fractures in women was associated with the FRAX score [%/10 years] at baseline (HR 1.04; 95% CI, 1.02-1.07; P < 0.001) and administration of pioglitazone at 1 year after randomization (HR 1.59; 95% CI, 1.06-2.38; P = 0.025). CONCLUSIONS Intensified multifactorial intervention may be implemented without increasing the fracture risk in patients with type 2 diabetes. The fracture risk is elevated in those with a history of smoking in men, whereas it is predicted by the FRAX score and is independently elevated with administration of pioglitazone in women.

Abstract
The purpose of this review is to examine the correlation between tobacco smoking and hip fractures. The literature that was used for this article was based on studies that investigated not only the direct correlation between smoking and hip fractures but also the effect of smoking on bone mineral density. In general, the incidence of hip fracture was found to be higher in current smokers in both genders. Compared with never smokers, former smokers had a slightly higher risk of hip fracture that was inversely proportional to the cessation span. The relative risk (RR) of hip fracture in current male smokers was higher than the RR for nonsmokers (never and former smokers). In postmenopausal women former and current smoking increased the RR. In premenopausal and postmenopausal women, cessation of smoking decreases the risk of hip fracture. Risk rises with greater cigarette consumption. Risk declines among former smokers, but the benefit is not observed until 10 years after cessation.

Abstract
BACKGROUND Several observational studies have suggested an association between cigarette smoking and risk of hip fracture. However, no formal systematic review or meta-analysis was performed to summarize this risk in men. MATERIALS AND METHODS A search was applied to MEDLINE, EMBASE, and web of science (up to November 1 2016). All prospective cohort studies assessing risk of hip fracture with the factor of cigarette smoking in men without language restriction were reviewed, and qualities of all included studies were assessed using the Newcastle-Ottawa Scale. Two authors independently assessed literatures and extracted information eligibility, and any disagreement was resolved by consensus. Newcastle-Ottawa quality assessment scale was used to evaluate studies' quality in meta-analyses. We calculated the RR with 95% CIs in a random-effects model as well as the fixed-effects model using the metan command in the STATA version 12.0 (StataCorp, USA). RESULTS Fourteen prospective cohort studies were eligible for the present analysis. A meta-analysis of 12 prospective studies showed that the relative risk (RR) for current male smoking was 1.47 [95% confidence interval (CI) (1.28-1.66), p = 0.54; I2 = 0%]. Subgroup analyses show study characteristics (including geography region, length of follow-up, size of cohorts and study quality) did not substantially influence these positive associations. Eight studies reported the RRs for former smokers compared with never smokers and the pooled RR was 1.15 [95% CI, (0.97-1.34), (I2 = 0%, p = 0.975)]. CONCLUSIONS The present meta-analysis of 14 prospective studies suggests that, compared with never smokers, cigarette smoking increases risk of hip fracture in man, specifically in current smokers. However, further larger prospective cohorts with more power or meta-analysis of individual patient data are needed to confirm this association.

Abstract
BACKGROUND AND OBJECTIVES Whether cigarette smoking can increase the risk of hip fracture in women is unclear. This meta-analysis, which pooled results from 10 prospective cohort studies, was performed to derive a more precise estimation between cigarette smoking and the risk of hip fracture in women. MATERIALS AND METHODS Pubmed, Cochrane Central Register of Controlled Trials and ISI Web of Science were systematically searched to identify relevant studies. A meta-analysis was performed to examine the association among 10 studies. The pooled risk estimates were calculated by using both random- and fixed-effects model. Heterogeneity among articles and their publications bias were also tested. All of the statistical analyses were performed using the software programs STATA (version 12.0). RESULTS Relative risk was significantly increased in current female smokers (pooled RR, 1.30; 95%CI, 1.16-1.45). The association was significant among the high-dose smokers (more than 15 cigarettes per day) while not among the low-does smokers (less than 15 cigarettes per day). Omission of any single study had little effect on the pooled risk estimate. Former smokers had a similar RR of hip fracture (RR, 1.02; 95%CI, 0.93-1.11) to published papers. Smoking cessation for ≥10 years leads to a significant decline in risk. CONCLUSIONS Smoking is associated with an increased hip fracture risk in women. Cessation of smoking for ≥10 years had a decreased impact on risk of hip fracture. Given the inconsistency among the studies in the choice of adjustments, the associations between cigarette smoking and risk of hip fracture in women await further investigation.

Abstract
Lower bone mineral density (BMD) in smokers may be attributable to lower body weight or fat mass, rather than to a direct effect of smoking. We analyzed the effects of smoking exposure, assessed by plasma cotinine, and body fat on BMD and the risk of subsequent hip fracture. In the community-based Hordaland Health Study (HUSK), 3003 participants 46-49 years and 2091 subjects 71-74 years were included. Cotinine was measured in plasma and information on health behaviors was obtained from self-administered questionnaires. BMD and total body soft tissue composition were measured by dual X-ray absorptiometry. Information on hip fracture was obtained from computerized records containing discharge diagnoses for hospitalizations between baseline examinations 1997-2000 through December 31st, 2009. In the whole cohort, moderate and heavy smokers had stronger positive associations between fat mass and BMD compared to never smokers (differences in regression coefficient (95% CI) per % change in fat mass = 1.38 (0.24, 2.52) and 1.29 (0.17, 2.4), respectively). In moderate and heavy smokers there was a nonlinear association between BMD and fat mass with a stronger positive association at low compared to high levels of fat mass (Davies segmented test, p<0.001). In elderly women and men, heavy smokers had an increased risk of hip fracture compared to never smokers (hazard ratio = 3.31, 95% CI: 2.05, 5.35; p<0.001). In heavy smokers there was a tendency of a lower risk of hip fracture with higher percentage of fat mass. The deleterious effect of smoking on bone health is stronger in lean smokers than in smokers with high fat mass.

Abstract
Osteoporosis is a common, morbid and costly disorder characterized by deterioration in bone strength. Cigarette smoking is associated with reduced bone mineral density (BMD) and increased fracture risk. There are basic, clinical, and observational studies that define several of the underlying pathophysiologic mechanisms that predispose smokers to bone loss. Such mechanisms include alterations in calciotropic hormone metabolism and intestinal calcium absorption, dysregulation in sex hormone production and metabolism, alterations in adrenal cortical hormone metabolism and in the receptor activator of nuclear factor kappa-B (RANK), receptor activator of nuclear factor kappa-B ligand (RANKL), and osteoprotegerin (OPG) system (RANK-RANKL-OPG system), and direct cellular effects of cigarette use on bone cells. In addition, there is evidence of reversibility in the aforementioned mechanisms with smoking cessation. In summary, cigarette smoking is a reversible risk factor for osteoporosis and osteoporotic fractures through diverse pathophysiologic mechanisms.

Abstract
UNLABELLED The role of smoking on fracture risk in older men was studied within a longitudinal population-based cohort study. Using time-dependent exposure information and analysis, smoking was detected to be a stronger, dose-dependent and a more long lasting risk factor for fracture than has previously been estimated. INTRODUCTION Although several studies have indicated a negative influence of smoking on fracture risk in women, there are few studies in men. No study in either sex has considered that smoking exposure may vary during follow-up in a cohort study. There is a need for a prospective study with repeated measures to analyze smoking exposure and fracture risk in men. MATERIALS AND METHODS A total of 2322 men, 49-51 years of age, were enrolled in a longitudinal, population-based cohort study. Smoking status and other lifestyle habits were established at baseline and additionally at 60, 70, and 77 years of age. One or more fractures were documented in 272 men during 30 years of follow-up. Cox proportional hazards regression was used to determine the rate ratio (RR) of fracture according to time-dependent smoking habits and covariates. RESULTS The overall adjusted fracture risk was increased in current (RR, 2.71; 95% CI, 1.86-3.95) and former smokers (RR, 1.66, 95% CI; 1.18-2.34), and persistent until 30 years after cessation. Among current smokers, the adjusted risk of any fracture increased by 30% (95% CI, 6-58%) for every 5 g of tobacco smoked each day. Smoking duration did not substantially influence fracture risk in either current or former smokers. One-half (52%; 95% CI, 35-65%) of all fractures were attributable to current smoking. CONCLUSIONS Tobacco smoking seems to be a long-lasting major risk factor for fracture in older men, and the risks depends both on recency of smoking and on the daily amount of tobacco smoked, rather than smoking duration.

Abstract
OBJECTIVES To assess fracture risk associated with smoking. DESIGN Systematic review. DATA SOURCES Cohort, case-control, and cross-sectional studies identified by searching PubMed and EMBASE, and by recursive screening of reference lists. SUBJECTS Fifty studies including 512 399 subjects were included. MAIN OUTCOME MEASURE Fracture occurrence in current, previous, and never smokers. RESULTS Fracture risk was significantly increased in current smokers for all fracture types combined (pooled relative risk 1.26, 95% CI 1.12-1.42) and for hip (1.39, 95% CI 1.23-1.58) and spine fractures (1.76, 95% CI 1.10-2.82), but not for wrist fractures (0.86, 95% CI 0.46-1.60). In previous smokers the estimate was significantly lower for as well all types of fractures (1.02, 95% CI 0.85-1.22, P = 0.03 compared with current smokers), as for hip fractures (1.19, 95% CI 1.06-1.34, P = 0.04). There was a trend towards higher risk estimates in previous smokers for hip fractures in case-control studies than in cohort studies. A similar difference between case-control and cohort studies was not present for current smokers. There was a geographical heterogeneity: the risk of hip fractures associated with current smoking increased with latitude, i.e. the risk was higher in Northern Europe and the USA than in Southern Europe and countries close to the equator. CONCLUSIONS Smoking is associated with an increased overall fracture risk, an increased risk of hip and spine but not wrist fractures. Cessation of smoking seems associated with a decrease in fracture risk. The impact of smoking varied geographically with an increase with latitude.

Abstract
The high rate of osteoporotic fracture in Western populations has resulted in a significant burden in terms of morbidity, mortality and health care costs. The use of DXA has made the diagnosis of osteoporosis easier and identified a subgroup of individuals who are at a higher risk of fracture. It is a useful tool in determining therapy in those at greatest risk of fracture. However, widespread use of such treatments is low and greater uptake remains an elusive goal. There are now many different treatments that reduce fracture rate, and can accompany lifestyle measures such as smoking cessation, diet and exercise. Dietary supplementation with calcium has been shown to reduce the risk of vertebral fracture, and the combination of calcium with vitamin D has been shown to reduce fracture at non-vertebral sites, including the hip. Although ERT, SERMs and tibolone all retard bone loss, prospective fracture prevention has only been shown for SERMs and then only at the spine. Bisphosphonates represent a class of potent anti-resorptive agents, which have been shown to reduce fracture rate at vertebral and non-vertebral sites. Other agents such as calcitonin, PTH and fluoride are of less certain benefit in preventing fracture.

Abstract
Osteoporosis affects approximately 10 million Americans; of these, 2 million are men. An estimated 3.5 million additional men are at risk of developing the disease. Individuals with osteoporosis commonly incur fractures of the spine, hip, and forearm. The clinical spectrum of osteoporosis is similar in men and women; however, differences exist in skeletal development, age-related bone loss, modifiable and nonmodifiable risk factors, and secondary causes. Prevention and early detection is achieved through identification of risk factors and secondary causes. Treatment options include risk factor reduction, correction of underlying disease, and use of pharmacologic and nonpharmacologic therapies.

Abstract
Currently, there are more than 50 million smokers in this country, and approximately 800 billion cigarettes are smoked each year. Smoking is now the leading avoidable cause of morbidity and mortality in the United States. According to one report, over 500,000 deaths per year in the United States alone can be attributed to smoking. For years, orthopaedic surgeons have known about the relationships that putatively exist between smoking and an array of orthopaedic conditions and complications. It has been shown to adversely affect bone mineral density, lumbar disk disease, the rate of hip fractures, and the dynamics of bone and wound healing. Although scientific and clinical information on smoking and its consequences suggests differing degrees of correlation between smoking and orthopaedic conditions, most available data do suggest a real and reproducible relationship. In the past, there have been many individual reports that deal with these relationships separately but very few published comprehensive reviews. This summary of the current literature regarding the relationship between smoking and musculoskeletal diseases and their treatment provides information that can be used clinically by both the practitioner and the patient.

Abstract
BACKGROUND Previous findings suggest that tobacco smoking increases the risk of hip fracture in women. A similar adverse effect of smoking is suspected to be present in men, but bone mineral density studies have raised the concern that men may be more sensitive to the deleterious effect of smoking on bone than women. In this study we prospectively determined the influence of current, previous, and cumulative smoking history on risk of hip fracture in men and women and addressed the issue of possible gender difference in the susceptibility to tobacco smoking. METHODS Pooled data from three population studies conducted in Copenhagen with detailed information on smoking habit. A total of 13,393 women and 17,379 men, initially examined between 1964 and 1992, were followed until 1997 for first admission due to hip fracture. The relative risks (RR) of hip fracture associated with smoking were estimated by means of multiplicative Poisson regression models. RESULTS During follow-up, 722 hip fractures were identified in women, and 447 in men. After adjustment for potential confounders, including body mass index, female current smokers had an RR of hip fracture of 1.36 (95% CI: 1.12-1.65) and male smokers 1.59 (95% CI: 1.04-2.43) relative to never smokers. In both sexes, the RR of hip fracture gradually increased by current and accumulated tobacco consumption. The RR were consistently higher in men than in women, but the test for interaction between sex and tobacco smoking was insignificant. After 5 years, male ex-smokers had an adjusted RR of 0.73 (95% CI: 0.55-0.98) relative to current smokers, while no significant decrease in risk was observed in female ex-smokers (RR = 0.91; 95% CI: 0.72-1.17)). Approximately 19% of all hip fractures in the present study population were attributable to tobacco smoking. CONCLUSION Tobacco smoking is an independent risk factor for hip fracture in men and women, and there appears to be no gender differences in smoking related risk. Smoking cessation reduces the risk of hip fracture in men after 5 years, while the deleterious effect of smoking seems to be more long-lasting in female ex-smokers.

Abstract
OBJECTIVE Mental distress may entail increased risk of hip fracture, but it is uncertain whether the effect consists solely of an indirect effect through use of medication, or whether it is also mediated through other mechanism. The purpose of this study was to examine the association between mental distress and risk of hip fracture in women, adjusted for medication (that is, use of tranquillisers/sedatives or hypnotics). DESIGN A three year follow up of hip fracture was conducted on 18,612 women, consisting of 92.5% of all women aged 50 years or older in a Norwegian county. Three hundred and twenty nine suffered a hip fracture. A mental distress index was based on questions about life dissatisfaction, nervousness, loneliness, sleep disorders, troubled and uneasy feelings, depression and impairment attributable to psychological complaints. Relative risk with 95% confidence intervals (CI) of hip fracture with respect to mental distress were controlled for medication, age, body mass index (BMI), smoking, physical inactivity, and physical illness by means of Cox regression. RESULTS The 10% of women with the highest mental distress had more than twofold increased risk of hip fracture compared with the 10% of women with the lowest mental distress, after adjustment for age and medication. The relative risk was 1.95 (95% CI 1.2, 3.3) after additional control for BMI, smoking, physical inactivity, and physical illness. The relative risk of hip fracture for daily users of medication compared with never users was 2.1 (95% CI 1.6, 2.9). After adjusting for mental distress it was 1.5 (95% CI 1.0, 2.2). CONCLUSIONS Risk of hip fracture was positively related to mental distress, also after adjustment for medication use. The effect of tranquillisers/sedatives or hypnotics on hip fracture risk may be overestimated in studies with no adjustments for mental distress.
