Marital Status, Cardiovascular Diseases, and Cardiovascular Risk Factors: A Review of the Evidence

The influence of partners on successful lifestyle modification in patients with coronary artery disease

BACKGROUND

Marital status is associated with prognosis in patients with cardiovascular disease (CVD). However, the influence of partners on successful modification of lifestyle-related risk factors (LRFs) in secondary CVD prevention is unclear. Therefore, we studied the association between the presence of a partner, partner participation in lifestyle interventions and LRF modification in patients with coronary artery disease (CAD).

METHODS

In a secondary analysis of the RESPONSE-2 trial (n = 711), which compared nurse-coordinated referral to community-based lifestyle programs (smoking cessation, weight reduction and/or physical activity) to usual care in patients with CAD, we investigated the association between the presence of a partner and the level of partner participation on improvement in >1 LRF (urinary cotinine <200 ng/l, ≥5% weight reduction, ≥10% increased 6-min walking distance) without deterioration in other LRFs at 12 months follow-up.

RESULTS

The proportion of patients with a partner was 80% (571/711); 19% women (108/571). In the intervention group, 48% (141/293) had a participating partner in ≥1 lifestyle program. Overall, the presence of a partner was associated with patients' successful LRF modification (adjusted risk ratio (aRR) 1.93, 95% confidence interval (CI) 1.40-2.51). A participating partner was associated with successful weight reduction (aRR 1.73, 95% CI 1.15-2.35).

CONCLUSION

The presence of a partner is associated with LRF improvement in patients with CAD. Moreover, patients with partners participating in lifestyle programs are more successful in reducing weight. Involving partners of CAD patients in weight reduction interventions should be considered in routine practice.

Cause-specific mortality after diagnosis of thyroid cancer: a large population-based study

PURPOSE

The study aimed to disclose mortality pattern and quantitatively evaluate risks for cause-specific mortality among thyroid cancer survivors.

METHODS

We included 173,710 patients from the Surveillance, Epidemiology, and End Results (SEER) database with thyroid cancer diagnosed between 1975 and 2015. Standardized mortality ratio (SMR) was calculated using general US population as the reference. Cumulative incidence function curves were constructed to elaborate crude cause-specific mortality by histology. Cox proportional hazards regression model was adopted to identify predictors for cause-specific mortality, expressed as hazard ratio (HR) and 95% confidence interval (CI).

RESULTS

After a median follow-up of 101 months, 23,040 (13.3%) deaths occurred, of which 29.1% and 21.7% were attributable to thyroid cancer and cardiovascular disease (CVD), respectively. CVD SMRs were 1.14, 1.47, 1.21, and 5.66 in patients with follicular, Hürthle cell, medullary and anaplastic histology, respectively. The adjusted HRs of thyroid cancer-specific mortality were 1.59 (95% CI: 1.46-1.74), 1.87 (95% CI: 1.65-2.12), 3.66 (95% CI: 3.31-4.05), and 12.65 (95% CI: 11.50-13.92) for follicular, Hürthle cell, medullary, and anaplastic histology, respectively, as compared with papillary histology; HRs of CVD-specific mortality were 1.23 (95% CI: 1.12-1.34), 1.27 (95% CI: 1.11-1.46), 1.13 (95% CI: 0.96-1.33), and 1.60 (95% CI: 1.19-2.16), respectively. Older age, male sex, nonwhite race, unmarried status, and advanced stage were independent predictors of CVD-specific mortality, while receiving surgery and radiotherapy were protective against CVD-specific mortality.

CONCLUSIONS

We disclosed distinct mortality patterns by histology and identified predictors of CVD-specific mortality in thyroid cancer survivors, supporting CVD intervention for aggressive thyroid cancer.

Do Sex-Related Differences of Comorbidity Burden and/or In-Hospital Mortality Exist in Cancer Patients? A Retrospective Study in an Internal Medicine Setting

Cancer represents important comorbidity, and data on outcomes are usually derived from selected oncologic units. Our aim was to evaluate possible sex-related differences and factors associated with in-hospital mortality (IHM) in a consecutive cohort of elderly patients with cancer admitted to internal medicine. We included all patients admitted to our department with a diagnosis of cancer during 2018. Based on the International Classification of Diseases, 9th Revision, Clinical Modification, demography, comorbidity burden, and diagnostic procedures were evaluated, with IHM as our outcome. We evaluated 955 subjects with cancer (23.9% of total hospital admissions), 42.9% were males, and the mean age was 76.4 ± 11.4 years. Metastatic cancer was diagnosed in 18.2%. The deceased group had a higher modified Elixhauser Index (17.6 ± 7.7 vs. 14 ± 7.3, p < 0.001), prevalence of cachexia (17.9% vs. 7.2%, p < 0.001), and presence of metastasis (27.8% vs. 16.3%, p = 0.001) than survivors. Females had a higher age (77.4 ± 11.4 vs. 75.5 ± 11.4, p = 0.013), and lower comorbidity (10.2 ± 5.9 vs. 12.0 ± 5.6, p < 0.001) than males. IHM was not significantly different among sex groups, but it was independently associated with cachexia and metastasis only in women. Comorbidities are highly prevalent in patients with cancer admitted to the internal medicine setting and are associated with an increased risk of all-cause mortality, especially in female elderly patients with advanced disease.

Marital status and outcomes in chronic heart failure: Does it make a difference of being married, widow or widower?

OBJECTIVE:

We aimed to compare the outcomes of chronic heart failure (HF) patients with reduced ejection fraction (CHFrEF) in the Turkish Research Team in HF (TREAT-HF) registry according to marital status with a specific focus on being the widowed (widow/widower) versus the married.

METHODS:

TREAT-HF is a network, enrolling CHFrEF with a follow up for HF-related hospitalization (HFrH) and all-cause mortality (ACM). In this cohort, the widowed patients were compared with patients who were married before and after propensity score (PS) matching analysis.

RESULTS:

There were 723 cHFrEF patients with a complete dataset, including reported marital status at baseline for this analysis. Out of 723 patients with HF, 37 “never-married” and “divorced” patients were excluded from the analysis. Then, out of 686 remaining patients with HF, who had at least one reported marriage in the database, widowed patients with HF (n=124) were compared with married patients (n=562). The mean follow up period was 21±12 months up to 48 months. The widowed patients had a higher risk of HFrH (p=0.047), although ACM remained similar compared to married patients (p=0.054). After PS matching, HFrH remained more frequent among the widowed compared with the married (p=0.039) although ACM yielded similar rates. Of note, it was shown that being a widower (p=0.419) was not linked to increased risk of HFrH during follow up contrary to being a widow (p=0.037) despite similar age, ejection fraction, creatinine, NYHA functional class distribution and a similar rate of life-saving medications.

CONCLUSION:

PS matching analysis yielded that the widowed had increased the risk for HFrH. Of note, widowers did not seem to have an increased risk for HFrH, contrary to widows.

The effects of marital status on outcome of heart failure population: a systematic review and meta-analysis

BACKGROUND

Traditional risk factors for worse outcome in heart failure (HF) are well-established. However, there are still many unknown risk factors for worse outcome in this population. Several studies have shown that unmarried status is associated with an increased risk of rehospitalization and mortality in HF patients. However, there is no systematic review or meta-analysis to confirm this association. We performed a systematic review and meta-analysis to explore the effect of marital status on outcome regarding mortality and rehospitalization in HF population.

METHODS

We searched the databases of MEDLINE and EMBASE from inception to July 2019. Included studies were published cohort studies or randomised controlled trials reporting rates of mortality and/or rehospitalization in HF patients, married and unmarried. Data from each study were combined using the random-effects model.

RESULTS

Ten studies were included in our meta-analysis. We found that unmarried status is associated with increased risk of mortality (pooled OR = 1.52, 95%CI = 1.30-1.78, p < .001), increased risk of rehospitalization (pooled OR = 1.80, 95%CI = 1.18-2.74, p = .007), and increased risk of combined endpoint of mortality and rehospitalization (pooled OR = 1.72, 95%CI = 1.36-2.17, p < .001).

CONCLUSIONS

Our meta-analysis demonstrated that being unmarried, divorced, and widowed is associated with a worse outcome in HF population regarding mortality and rehospitalization rate.

Cardiovascular Risk and Factors Associated to the Health in Hypertensive African Descent People Resident in Quilombola Community

Introduction: Hypertension is a cardiovascular risk factor of wide magnitude among people of African descent, especially those living in Quilombos. However, little is known about the factors associated with cardiovascular risk in residents of the urban Quilombola community. Objetive: To analyze the cardiovascular risk and health-related factors in the family context of hypertensive Afro-descendants living in an urban Quilombola. Materials and methods: It is a cross-sectional and community-based study carried out from November 2017 to March 2018. The study’s population consisted of 303 hypertensive patients enrolled in the family health unit, with ages ranging from 35 to 79 years old, of both genders; and using antihypertensive drugs. The instruments used for data production were: The Primary Arterial Hypertension Questionnaire and the Framingham Risk Score. Results: There was a significant association between cardiovascular risk and cardiovascular disease (CVD) family history (p<0.011), type II diabetes (p<0.001) and overweight and obesity (p<0.010). Conclusion. Research has shown that hypertensive Quilombola people have consistent cardiovascular risk outcomes, especially with CVD family history, type II diabetes, overweight and obesity, schooling and gender with significant associations.

The Effects of Long-Term Tai-Chi Practice on Blood Pressure Under Normal Conditions

BACKGROUND

Tai-Chi is a popular form of mind-body activity that is suitable for people of all ages. Accumulating evidence have shown that Tai-Chi can help ameliorate cardiovascular diseases. However, the benefits of long-term practice of Tai-Chi on blood pressure control remains unclear. A total of 898 villagers of Chenjiagou were enrolled in this study based on certain inclusion and exclusion criteria.

METHODS

All basic information and clinical data were collected by physicians. The effects of Tai-Chi on the systolic blood pressure (SBP), diastolic blood pressure (DBP) and mental status of participants were analyzed. The average practice time of Tai-Chi in the Tai-Chi group was 28.53 years (median 29 years, range 2-69 years).

RESULTS

The results showed that SBP and DBP were significantly lower in the Tai-Chi group, compared with the control group and the stop group. Meanwhile, the long-term practice of Tai-Chi significantly improved the body mass index (BMI) (P=0.021). Stepwise regression results demonstrated that Tai-Chi practice, age and BMI could significantly affect blood pressure, with adjusted R² of 0.218 and 0.159 for SBP and DBP, respectively. In addition, Tai-chi is associated with a lower rate of hypertension after age 40. However, compared with the control group, participants who practiced Tai-Chi for a short time, then stopped, showed no significant improvement in the above-mentioned measurements.

CONCLUSIONS

The long-term practice of Tai-Chi was associated with better blood pressure, at least partly through the improvement of BMI and mental state. However, the short-term practice of Tai-Chi may not provide significant benefits on blood pressure in the long term.

[Psychosocial stress, high blood pressure and cardiovascular risk]

Psychosocial stress can be the result of a wide variety of causes and circumstances. The experience of stress is often unique and experienced in a very personal way, although with common physiological responses. Predictably, it will increase in the modern world, which is subject to vertiginous social, cultural and technological changes. This review aims to determine the psychosocial factors that affect arterial hypertension (HT) and cardiovascular risk (CVR). Psychosocial stress more than doubles the risk of HT, the most related factors being post-traumatic stress disorder, anxiety and work stress. The factors that were most related to an increase in CVR were informal care, lower socioeconomic status, severe mental disorders, marital status, and post-traumatic stress disorder. Individual and collective psychosocial stress prevention strategies can be decisive in decreasing the prevalence of HT and CVR.

The Role of Emotional Regulation and Affective Balance on Health Perception in Cardiovascular Disease Patients According to Sex Differences

One of the challenges of aging is the increase of people with chronic diseases, such as cardiovascular disease (CVD). Men and women experience the disease differently. Therefore, it has an impact on how CVD is treated and its outcomes. This research analyzed the relationship between psychosocial variables and health promotion among cardiovascular patients, paying special attention to sex differences. A longitudinal study with cardiovascular patients (747 in phase 1 (122 women) and 586 in phase 2 (83 women)) was carried out. Participants were evaluated based on their sociodemographic characteristics, affective balance, regulatory negative affect self-efficacy, stress and anxiety regulation strategies, and perceived global health. Results showed that men presented significantly higher scores in positive affect, affective balance, and self-efficacy to regulate negative emotions, while women presented significantly higher scores in negative affect and the use of passive strategies to cope with stressful situations. Regression analyses showed that all psychological variables studied in phase 1 were significant predictors of health perception in phase 2. According to the results, it is necessary to include strategies to improve cardiovascular health through education and emotional regulation, with a gender focus.

Shift work, and particularly permanent night shifts, promote dyslipidaemia: A systematic review and meta-analysis

BACKGROUND AND AIMS

Shift work is common worldwide and linked to deleterious cardiovascular effects that might be underlined by dyslipidemia. The aim of this systematic review and meta-analysis is to determine the impact of shiftwork on dyslipidemia.

METHODS

Searching in PubMed, Cochrane Library, Science Direct and Embase databases without language restriction on 15 February 2020, included studies that describe blood lipids levels or a risk measure in shift workers compared with fixed-day workers (controls). Differences by study-level characteristics were estimated using stratified meta-analysis by type of shift work, and meta-regression to examine relations between dyslipidemia and demographic, lifestyle and work characteristics. Estimates were pooled using random-effect meta-analysis.

RESULTS

We included a total of 66 articles, representing 197,063 workers. Shift work globally increased the levels of triglycerides (overall SMD = 0.09; 95CI 0.05 to 0.13; p < 0.001), and globally decreased the levels of c-HDL (-0.08; 95CI -0.12 to -0.03; p = 0.001). Permanent night shift workers were an at-risk type of shift for dyslipidemia with significantly higher blood levels of total cholesterol (0.22; 95CI 0.01 to 0.42; p = 0.043) and triglycerides (0.18; 0.03 to 0.33; p = 0.017), and significantly lower blood levels of c-HDL (-0.16; 95CI -0.32 to 0.00; p = 0.05). Permanent night shift workers were more at-risk for total cholesterol than rotating 3 × 8 shift workers (Coefficient 0.22; 95CI 0.01 to 0.42; p = 0.038) and rotating 2 × 12 shift workers (0.24; 0.02 to 0.46; p = 0.037), and more at-risk for triglycerides than rotating day shift workers (0.21; 95CI 0.03 to 0.38; p = 0.023). Results were non-significant for c-LDL, nor depending on type of shifts.

CONCLUSIONS

Shift work, and particularly permanent night shift, is associated with dyslipidaemia via elevated total cholesterol and triglycerides, and reduced HDL-cholesterol. Our current study provides a practical and valuable strengthening of the evidence-base required for preventive health initiatives and workplace reform.

Social Support, Social Network Size, Social Strain, Stressful Life Events, and Coronary Heart Disease in Women With Type 2 Diabetes: A Cohort Study Based on the Women's Health Initiative

OBJECTIVE

We studied associations between social support, social network size, social strain, or stressful life events and risk of coronary heart disease (CHD) in postmenopausal women with type 2 diabetes.

RESEARCH DESIGN AND METHODS

From the Women's Health Initiative, 5,262 postmenopausal women with type 2 diabetes at baseline were included. Cox proportional hazards regression models adjusted for demographics, depressive symptoms, anthropometric variables, and lifestyle factors were used to examine associations between social factors and CHD.

RESULTS

A total of 672 case subjects with CHD were observed during an average 12.79 (SD 6.29) years of follow-up. There was a significant linear trend toward higher risk of CHD as the number of stressful life events increased (P for trend = 0.01; hazard ratio [HR] [95% CI] for the third and fourth quartiles compared with first quartile: 1.27 [1.03-1.56] and 1.30 [1.04-1.64]). Being married or in an intimate relationship was related to decreased risk of CHD (HR 0.82 [95% CI 0.69-0.97]).

CONCLUSIONS

Among postmenopausal women with type 2 diabetes, higher levels of stressful life events were associated with higher risk of CHD. Experience of stressful life events might be considered as a risk factor for CHD among women with type 2 diabetes.

Social Factors, Sex, and Mortality Risk After Coronary Artery Bypass Grafting: A Population-Based Cohort Study

Background Little is known of the impact of social factors on mortality after coronary artery bypass grafting ( CABG ). We explored sex- and age-specific associations between mortality risk after CABG and marital status, income, and education. Methods and Results This population-based register study included 110 742 CABG patients (21.3% women) from the SWEDEHEART registry (Swedish Web-system for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated According to Recommended Therapies) operated 1992 to 2015. Cox regression models were used to study the relation between social factors and all-cause mortality. Never having been married compared with being married/cohabiting was associated with a higher risk in women than in men (hazard ratio 1.32, 95% CI 1.20-1.44) versus 1.17 (1.13-1.22), P=0.030 between sex. The lowest income quintile, compared with the highest, was associated with higher risk in men than in women (hazard ratio 1.44 [1.38-1.51] versus 1.25 [1.14-1.38], P=0.0036). Lowest education level was associated with higher risk without sex difference (hazard ratio 1.15 [1.11-1.19] versus 1.25 [1.16-1.35], P=0.75). For unmarried women aged 60 years at surgery with low income and low education, mortality 10 years after surgery was 18%, compared with 11% in married women with high income and higher education level. The median life expectancy was 4.8 years shorter. Corresponding figures for 60-year-old men were 21% versus 12% mortality risk at 10 years and 5.0 years shorter life expectancy. Conclusions There are strong associations between social factors and mortality risk after CABG in both men and women. These results emphasize the importance of developing and implementing secondary prevention strategies for CABG patients with disadvantages in social factors.

Trajectories of rural-urban disparities in biological risks for cardiovascular disease among Chinese middle-aged and older adults

This study examined rural-urban differences in age trajectories of biological risks for cardiovascular disease (CVD) among Chinese middle-aged and older adults. Data were from the 2011 wave of China Health and Retirement Longitudinal Study, including 11,528 respondents (M_age = 59.15) from 440 communities. CVD risk factors included C-reactive protein (CRP), high-density lipoprotein (HDL), body mass index (BMI), and waist circumference (WC). Multilevel models revealed that rural adults had higher levels of HDL and lower levels of CRP and BMI on average, compared to urban adults. We also found significant rural-urban differences in the age trajectories of CVD risks. Rural-urban disparities in CVD risks increased from middle to later life, and converged at later old age. Findings suggest that rural-urban differences in cardiovascular health are not static, but rather vary throughout adulthood.

Risk Factors for Cancer-specific Mortality and Cardiovascular Mortality in Patients With Diffuse Large B-cell Lymphoma

BACKGROUND

The purpose of this study was to assess the risk factors for cancer-specific mortality and cardiovascular mortality in patients with diffuse large B-cell lymphoma (DLBCL).

PATIENTS AND METHODS

A retrospective cohort study involving patients with DLBCL who were registered in the Surveillance, Epidemiology, and End Results (SEER) database was performed. The risk factors for cancer-specific mortality and cardiovascular mortality were analyzed using the competing risk regression model.

RESULTS

A total of 62,950 patients with DLBCL were enrolled, of which 23,302 (37.50%) died of cancer and 2940 (4.70%) died of cardiovascular disease. The competing risk multivariate analysis displayed that age at diagnosis (hazard ratio [HR], 1.033; 95% confidence interval [CI], 1.032-1.034), marriedstatus (HR, 1.293; 95% CI, 1.241-1.347), black race (HR, 1.079; 95% CI, 1.021-1.139), and tumor stage (II: HR, 1.143; 95%CI, 1.095-1.192; III: HR, 1.459; 95% CI, 1.395-1.526; IV: HR, 1.961; 95% CI. 1.889-2.035) were the risk factors for cancer-specific mortality, but not female gender (HR, 0.938; 95% CI, 0.913,0.965) or treatment modalities (chemotherapy: HR, 0.522; 95% CI, 0.505-0.540; radiotherapy: HR, 0.782; 95% CI, 0.728-0.839; chemotherapy + radiotherapy: HR, 0.422; 95% CI, 0.403-0.441). Age at diagnosis (HR, 1.059; 95% CI, 1.055-1.062) and black race (HR, 1.246; 95% CI, 1.067-1.456) were the risk factors for cardiovascular mortality rather than female gender (HR, 0.803; 95% CI, 0.743-0.867) and married status (HR, 0.841; 95% CI, 0.745-0.950).

CONCLUSIONS

Age at diagnosis, married status, black race, and higher tumor stage are associated with an increased risk of cancer-specific mortality in patients with DLBCL, whereas age at diagnosis and black race are associated with a higher risk of cardiovascular mortality.

Patients' knowledge on cardiovascular risk factors and associated lifestyle behaviour in Ethiopia in 2018: A cross-sectional study

BACKGROUND

Cardiovascular disease (CVD) is posing a major public health challenge globally. Evidence reports significant gaps in knowledge of cardiovascular risk factors among patients with CVD. Despite the growing burden of cardiovascular disease in developing countries, there is limited data available to improve the awareness of this area, which is crucial for the implementation of prevention programs.

METHODS

A cross-sectional survey was conducted in two referral hospitals in Eastern Ethiopia from June-September 2018. Outpatients with a confirmed diagnosis cardiovascular conditions were eligible for participation in the study. A convenience sampling technique was used. The primary outcome of the study was knowledge of cardiovascular risk factors among patients with cardiovascular disease. The knowledge of cardiovascular disease risk factors was measured using a validated instrument (heart disease fact questionnaire). A score less than 70% was defined as suboptimal knowledge. Multivariable linear regression was used to examine the relationship between knowledge of cardiovascular risk factors and explanatory variables.

RESULTS

A total of 287 patients were enrolled in the study. Mean age was 47±11yrs and 56.4% of patients were females. More than half of patients (54%) had good knowledge on cardiovascular risk factors (scored>70%), whilst 46% demonstrated suboptimal knowledge levels in this area. Urban residency was associated with higher cardiovascular risk factors knowledge scores, whereas, never married and no formal education or lower education were identified as predictors of lower knowledge scores. There was no statistically significant association between knowledge of cardiovascular risk factors and actual cumulative risk behaviour.

CONCLUSION

Almost half of CVD patients in Ethiopia have suboptimal knowledge regarding cardiovascular risk factors. Residence, education level and marital status were associated with knowledge of cardiovascular risk factors. Implementation of innovative interventions and structured, nurse-led lifestyle counselling would be required to effectively guide patients in developing lifestyle modification and achieve sustainable behaviour change.

Factors associated with hypertension and its management among older rural Australians

OBJECTIVES

Hypertension is a leading risk factor for death and disability. We aimed to estimate the prevalence of hypertension in an older rural Australian cohort and identify predictors of hypertension management.

DESIGN

Analysis of cross-sectional data collected from participants in a prospective cohort study.

SETTING

The Victorian rural towns of Morwell and Sale in 2018-2019.

PARTICIPANTS

A weighted random sample of 1119 eligible participants from Morwell or Sale, aged ≥55-90 years for men and ≥60-90 years for women, was drawn from the Hazelwood Health Study's Adult Survey cohort.

MAIN OUTCOME MEASURES

Blood pressure, body mass index, left ventricular hypertrophy by electrocardiogram, estimated glomerular filtration rate and glycosylated haemoglobin (HbA_1c ) were measured. Participants with hypertension were categorised as managed, undermanaged or unmanaged.

RESULTS

Testing undertaken of 498 participants estimated the weighted prevalence of hypertension (defined as blood pressure ≥ 140/90 mm Hg, a self-reported doctor diagnosis of hypertension or taking antihypertensive medication) to be 79.9% (95% confidence interval: 75.7-83.4). Of those, 54.5% (49.4-60.0) had managed hypertension (<140/90 mm Hg), 37.1% (32.3-42.1) undermanaged hypertension and 8.4% (5.9-11.9) a new finding of hypertension (unmanaged hypertension). Current employment (relative risk 1.47, 95% confidence interval: 1.06-2.02) and single marital status (relative risk 1.45, 1.4-1.84) were associated with under- or unmanaged hypertension. Compared with no hypertension, the hypertensive groups were more likely to demonstrate markers of end-organ damage such as left ventricular hypertrophy and impaired renal function.

CONCLUSION

Hypertension is a highly prevalent condition among older rural Australians which is suboptimally identified and managed.

Sociodemographic Determinants of Acute Myocardial Infarction Hospitalization Risks in Florida

Background Identifying social determinants of myocardial infarction (MI) hospitalizations is crucial for reducing/eliminating health disparities. Therefore, our objectives were to identify sociodemographic determinants of MI hospitalization risks and to assess if the impacts of these determinants vary by geographic location in Florida. Methods and Results This is a retrospective ecologic study at the county level. We obtained data for principal and secondary MI hospitalizations for Florida residents for the 2005-2014 period and calculated age- and sex-adjusted MI hospitalization risks. We used a multivariable negative binomial model to identify sociodemographic determinants of MI hospitalization risks and a geographically weighted negative binomial model to assess if the strength of associations vary by location. There were 645 935 MI hospitalizations (median age, 72 years; 58.1%, men; 73.9%, white). Age- and sex-adjusted risks ranged from 18.49 to 69.48 cases/10 000 persons, and they were significantly higher in counties with low education levels (risk ratio [RR]=1.033, P<0.0001) and high divorce rate (RR, 0.995; P=0.018). However, they were significantly lower in counties with high proportions of rural (RR, 0.996; P<0.0001), black (RR, 1.026; P=0.032), and uninsured populations (RR, 0.983; P=0.040). Associations of MI hospitalization risks with education level and uninsured rate varied geographically (P for non-stationarity test=0.001 and 0.043, respectively), with strongest associations in southern Florida (RR for <high school education, 1.036-1.041; RR for uninsured rate, 0.971-0.976). Conclusions Black race, divorce, rural residence, low education level, and lack of health insurance were significant determinants of MI hospitalization risks, but associations with the latter 2 were stronger in southern Florida. Thus, interventions for addressing MI hospitalization risks need to prioritize these populations and allocate resources based on empirical evidence from global and local models for maximum efficiency and effectiveness.

Are Spouses' Sleep Problems a Mechanism Through Which Health is Compromised? Evidence Regarding Insomnia and Heart Disease

BACKGROUND

Symptoms of insomnia have been widely identified as risk factors for health, including heart disease. Despite the expansive and growing literature on health concordance among coupled individuals, few studies have examined insomnia as a shared risk factor for heart disease among middle-aged and older couples.

PURPOSE

This study examined the association between insomnia and incident heart disease among couples. A dyadic modeling approach was employed to investigate the relationships between one's own insomnia and partners' insomnia for the risk of incident heart disease for each partner.

METHODS

Data from the 2010, 2012, and 2014 Health and Retirement Study were utilized in a prospective research design (N = 3,221 couples). Actor-partner interdependence models were employed to estimate actor and partner effects of insomnia symptoms for incident heart disease over the 4 year observation period.

RESULTS

Insomnia symptoms measured at baseline were related to an increased risk for heart disease for husbands, whereas for wives the association was attenuated after other health measures were controlled. Wives' insomnia was related to an increased risk of incident heart disease for husbands but husbands' insomnia was not related to wives' risk of heart disease.

CONCLUSIONS

This study showed how subjective insomnia symptoms among middle-aged and older adults in intimate partnerships are associated with their heart disease risk. Further research is needed to verify the results with objective measures of sleep problems and heart disease.

Learning a new way of living together: a qualitative study exploring the relationship changes and intervention needs of patients with cardiovascular disease and their partners

OBJECTIVES

Cardiovascular disease (CVD) not only affects the patient, but has implications for the partner. Emerging evidence suggests that supportive couple relationships enhance CVD outcomes and reduce patient and partner distress. To date, however, little research has been done to address the couple relationship as a potentially important component of cardiac care. This article examines the impact of CVD on the couple relationship and assesses the perceived needs and desired intervention components of patients with CVD and their partners.

DESIGN

Qualitative study using directed and conventional content analysis.

SETTING

Single-centre, tertiary cardiac care hospital that serves a population of 1.4 million in the Champlain region of Ontario, Canada.

PARTICIPANTS

Patients with CVD and their partners (n=32, 16 couples) participated in focus groups. Patients were mainly male (75%), white (87.5%), aged 64.4 years (range 31-81 years), with varied cardiac diagnoses (50% coronary artery disease; 18.75% valve disease; 18.75% heart failure; 12.5% arrhythmia).

RESULTS

Five categories were generated from the data reflecting changes within the couple relationship as a result of CVD: (1) emotional and communication disconnection; (2) overprotection of the patient; (3) role changes; (4) adjustment to lifestyle changes; and (5) positive relationship changes. Three categories were constructed regarding intervention needs and desired resources: (1) practical resources; (2) sharing with peers; and (3) relationship enhancement.

CONCLUSIONS

Overall, the data suggest that there were profound changes in the couple relationship as a result of CVD, and that there is considerable need to better support the caregiving spouses and the couple as a unit. These results call for interventions designed to provide instrumental support, peer-sharing opportunities and relationship quality enhancement to help couples cope with CVD. Future studies should examine whether couples-based programming embedded into cardiac rehabilitation can be effective at improving relationship quality and reducing patient and partner stress in the aftermath of a cardiac event.

Sex differences in the association between marital status and the risk of cardiovascular, cancer, and all-cause mortality: a systematic review and meta-analysis of 7,881,040 individuals

Purpose

To ascertain whether sex differences exist in the relationship between marital status and cardiovascular diseases (CVD), coronary heart disease (CHD), cancer and all-cause mortality in the general population and to explore the potential effect of age, location, the duration of follow-up and publication years on these outcomes.

Methods

A systematic search was performed in PubMed and EMBASE from inception through to April 2018 and review of references to obtain sex-specific relative risks and their 95% confidence intervals. These were used to derive the women-to-men ratio of RRs (RRR) and 95% CI for each study. RRs and RRRs for each outcome were then pooled using random effects inverse-variance weighted meta-analysis.

Results

Twenty-one studies with 7,891,623 individuals and 1,888,752 deaths were included in the meta-analysis. Compared with married individuals, being unmarried was significantly associated with all-cause, cancer, CVD and coronary heart disease mortalities for both sexes. However, the association with CVD and all-cause mortality was stronger in men. Being divorced/separated was associated with a higher risk of all-cause mortality in men and a stronger risk of cancer and CVD mortality. The pooled ratio for women versus men showed 31 and 9% greater risk of stroke mortality and all-cause mortality associated with never married in men than in women.

Conclusions

Being unmarried conferred higher risk of stroke and all-cause mortality for men than women. Moreover, divorced/separated men had higher risk of cancer mortality and CVD mortality. Further studies are warranted to clarify the biological, behavioral, and/or social mechanisms involved in sex differences by these associations.

Who does what the cardiologist recommends? Psychosocial markers of unhealthy behavior in coronary disease patients

Patients diagnosed with coronary heart disease should follow lifestyle recommendations that can reduce their cardiovascular risk (e.g., avoid smoking). However, some patients fail to follow these recommendations and engage in unhealthy behavior. With the aim to identify psychosocial factors that characterize patients at high risk of repeated cardiovascular events, we investigated the relationship between social support, mental health (coping, self-esteem, and perceived stress), and unhealthy behavior. We conducted a cross-sectional study of 419 patients recently diagnosed with coronary heart disease (myocardial infarction or angina) who participated in the National Health Survey in Spain (2018). Unhealthy behaviors were defined according to the European Guidelines on cardiovascular disease prevention. Only 1% of patients reported no unhealthy behaviors, with 11% reporting one, 40% two, 35% three, and 13% four or more unhealthy behaviors. In multiple regression controlling for demographic and traditional risk factors, mental health was the only significant psychosocial factor, doubling the odds of accumulated unhealthy behaviors, OR(high vs. low) = 2.03, 95% CI [1.14, 3.64]. Mental health was especially strongly related to unhealthy behavior among patients with obesity, OR(high vs. low) = 3.50, 95% CI [1.49, 8.45]. The relationship between mental health and unhealthy behaviors suggests that a large proportion of patients may not adhere to lifestyle recommendations not because they purposefully choose to do so, but because they lack coping skills to maintain the recommended healthy behaviors. Low mental well-being may be especially detrimental for behavior change of patients with obesity.

Ever Use of E-Cigarettes Among Adults in the United States: A Cross-Sectional Study of Sociodemographic Factors

E-cigarette use among adolescents is well-documented, but less is known about adult users of e-cigarettes. The purpose of this study was to examine associations between sociodemographic factors and e-cigarette use in a nationally representative sample of adults in the United States. Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) for years 2015-2016 were analyzed to assess e-cigarette use among 5989 adults aged ≥18 years. Multivariable logistic regression was conducted to examine associations between the sociodemographic exposures of age, sex, race, marital status, education level, employment status, and poverty-income ratio and the outcome of e-cigarette use. The weighted prevalence of ever use of e-cigarettes was 20%. Compared with adults aged ≥55 years, odds of e-cigarette use were 4.77 times (95% confidence interval [CI] = 3.63-6.27) higher among ages 18 to 34 years and 2.16 times (95% CI = 1.49-3.14) higher among ages 35 to 54 years. Higher odds of e-cigarette use were observed among widowed/divorced/separated participants compared with those who were married/living with a partner, among participants with less than high school (odds ratio [OR] = 1.47; 95% CI = 1.08-2.00) or high school/general educational development (GED) education (OR=1.41; 95% CI = 1.12-1.77) compared with those with college degrees/some college, and among those with incomes below the poverty level (OR=1.31; 95% CI = 1.01-1.69) compared with above the poverty level. For non-smokers of conventional cigarettes, higher odds of e-cigarette use were observed among males compared with females, Mexican Americans/Other Hispanics compared with non-Hispanic whites, and non-working participants compared with those who were working. Overall findings indicate that individuals who are widowed/divorced/separated, individuals with lower education, and with incomes below the poverty level are likely to report ever use of e-cigarettes. As increasing evidence demonstrates negative health consequences, e-cigarette initiation may ultimately contribute to additional smoking-related health inequalities even among non-smokers of conventional cigarettes.

Prevalence, determinants and association of unawareness of diabetes, hypertension and hypercholesterolemia with poor disease control in a multi-ethnic Asian population without cardiovascular disease

Background

To explore the prevalence and determinants of unawareness of diabetes, hypertension and hypercholesterolemia and its association with poor disease control in a multi-ethnic Asian population without cardiovascular disease (CVD).

Methods

We included 6904 Chinese, Malay and Indian individuals (mean age [SD] 58.2 [10.2] years; 52.6% female) with diabetes, hypertension and/or hypercholesterolemia from the cross-sectional population-based Singapore Epidemiology of Eye Diseases study (2004–2011). Diabetes was defined as random blood glucose ≥ 11.1 mmol/L or HbA1c > 6.5% or self-reported use of diabetes medication; hypertension as systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg or self-reported use of anti-hypertensive treatment; and hypercholesterolemia as total cholesterol ≥ 6.2 mmol/L or self-reported use of lipid-lowering medications. Unawareness was based on participants’ answers to the questions: “Did your medical practitioner ever tell you that you have diabetes/hypertension/high cholesterol?” The determinants of unawareness, and its association with poor disease control, were assessed using multivariable binary logistic regression models adjusted for known potential confounders.

Results

Of the 2380 (34.5%), 5386 (78.0%) and 3607 (52.2%) with diabetes, hypertension and hypercholesterolemia, respectively, unawareness rates were 30.7%, 43.1% and 40.9%, respectively. Having a higher BMI, particularly if obese, and Malay ethnicity were associated with greater unawareness of diabetes; Malay and Indian ethnicities and current smoking with greater unawareness of hypertension; and education ≤6 years, current smoking, and blue collar jobs or unemployment with greater unawareness of hypercholesterolemia (all P < 0.05). Lack of awareness of each condition was independently associated with poorer disease control in the case of hypertension and hypercholesterolemia, while the converse was true for diabetes (all P < 0.05).

Conclusions

Unawareness of diabetes, hypertension, or hypercholesterolemia is high in Singapore, with risk factors varying across all three diseases, although Malay ethnicity is a consistent one. Unawareness was also associated with poor management for hypertension and hypercholesterolemia. Public health education and screening programs should target at-risk individuals, especially Malays, to reduce the likelihood of incident CVD.

Marital status, telomere length and cardiovascular disease risk in a Swedish prospective cohort

OBJECTIVE

To investigate if marital status is associated with risk of cardiovascular disease (CVD) and to explore the potential influence of leucocyte telomere length (LTL), a marker of biological ageing, on such association.

DESIGN

Population-based prospective cohort study SETTINGS: Swedish Twin Registry.

PARTICIPANTS

Based on the Screening Across the Lifespan Twin Study from the Swedish Twin Registry, we included 10 058 twins born between 1900 and 1958 who underwent an interview between 1998 and 2002 during which information about marital status was collected. Blood samples from these participants were subsequently collected between 2004 and 2008 and used for LTL assessment using quantitative PCR technique.

MAIN OUTCOME MEASURES

Incident cases of CVD were identified through the Swedish Patient Register and Causes of Death Register through December 31, 2016. Multivariable linear regression and Cox proportional hazards regression models were used to estimate the regression coefficients (βs) and HRs with 95% CIs respectively. Potential confounders included age, sex, educational attainment and body mass index.

RESULTS

A total of 2010 participants were diagnosed with CVD during a median follow-up of 9.8 years. LTL was shorter among individuals living singly, including those who were divorced or separated (β:-0.014, 95% CI: -0.035, 0.007), widowed (β:-0.035, 95% CI: -0.061, -0.010), or living alone (β:-0.033, 95% CI: -0.052, -0.014), than individuals who were married or cohabitating. One SD increase of LTL was associated with a lower risk of CVD (HR: 0.79, 95% CI: 0.66, 0.93). Individuals who were divorced or separated, widowed, or living alone had a higher risk of CVD than individuals who were married or cohabitating. The summary HR of CVD was 1.21 (95% CI: 1.08, 1.35) when comparing individuals who were living singly, regardless of reason, with the individuals who were married or cohabitating. LTL appeared to mediate little of the association between marital status and CVD (HR additionally adjusted for LTL: 1.20; 95% CI: 1.08, 1.34).

CONCLUSIONS

Living singly, regardless of reason, was associated with a shorter LTL and a higher risk of CVD. The association between marital status and CVD was however not greatly attributable to telomere shortening.

The Association Between Marital Status, Coronary Computed Tomography Imaging Biomarkers, and Mortality in a Lung Cancer Screening Population

PURPOSE

The purpose of this study was to elucidate the impact of being unmarried on coronary computed tomography (CT) imaging biomarkers and mortality in a lung cancer screening population.

MATERIALS AND METHODS

In this retrospective case-control study, 5707 subjects (3777 married; mean age: 61.9±5.1 y and 1930 unmarried; mean age: 61.9±5.3 y) underwent low-dose CT as part of the National Lung Screening Trial (NLST). The median follow-up time was 6.5 (Q1-Q3: 5.6 to 6.9) years. Being unmarried was defined as never married, widowed, separated, or divorced. Being married was defined as married or living as married. Our primary endpoint was cardiovascular disease (CVD)-related death; our secondary endpoint was all-cause mortality. Coronary CT imaging biomarkers (calcium score, density, and volume) on low-dose chest CT scan were calculated using dedicated automatic software. Weighted Cox proportional-hazards regression was performed to examine the association between marital status and death. Kaplan-Meier curves were generated to visualize subject survival.

RESULTS

Being unmarried was significantly associated with an increased risk for CVD-related death (hazard ratio [HR]: 1.58; 95% confidence interval [CI]: 1.31-1.91) and all-cause mortality (HR: 1.39; 95% CI: 1.26-1.53), which remained significant even after adjusting for traditional cardiovascular risk factors (HR CVD death: 1.75; 1.44-2.12 and HR all-cause mortality: 1.58; 95% CI: 1.43-1.74) and coronary calcium score (HR CVD death: 1.58; 95% CI: 1.31-1.91 and HR all-cause mortality: 1.40; 95% CI: 1.27-1.54).

CONCLUSIONS

Being unmarried is associated with an increased CVD-related death and all-cause mortality mainly due to cardiovascular etiology. On the basis of this, marital status might be taken into consideration when assessing individuals' health status.

Associations of marital status with diabetes, hypertension, cardiovascular disease and all-cause mortality: A long term follow-up study

Background

To investigate the associations of marital status with major clinical outcomes including type 2 diabetes (T2D), hypertension, cardiovascular disease (CVD) and all-cause mortality.

Methods

The study cohort (1999–2014) included 9,737 (45% male) Iranian adults with a mean age of 47.6 years. Marital status was defined as married versus never married, divorced and widowed. The relationship between marital status and the four above mentioned outcomes were investigated using Cox regression models adjusted for the main confounders, specific to each outcome.

Results

After more than 12 years of follow-up, 1,889 (883 men) individuals developed hypertension, 1,038 (468 men) T2D, 1015 (597 men) CVD and 668 (409 men) all-cause mortality. Compared with married, being never married in men was associated with higher risk of hypertension [hazard ratio (HR): 1.55; 95% confidence interval (CI), 1.11–2.16] and all-cause mortality (2.17; 0.95–5.00; p-value = 0.066) after adjusting for confounders. Among women, compared with married status, widowed status was associated with a lower risk of T2D (0.74; 0.56–0.97) in the confounders adjusted model. Moreover, never married women had a lower risk of hypertension (0.58; 0.37–0.90) compared to married ones in the age adjusted model, a finding that did not achieve significance, after further adjustment for confounders.

Conclusion

We found that the relationship between marital status and health outcomes varied by gender. Being never married was an important risk factor for hypertension and tended to be a significant risk factor for mortality in men. However, among women, being widowed was associated with a lower risk of T2D.

Cardiovascular mortality among patients with non-Hodgkin lymphoma: Differences according to lymphoma subtype

Survival rates of patients with non-Hodgkin lymphoma (NHL) have improved over the last decade. However, cardiotoxicities remain important adverse consequences of treatment with chemotherapy and radiation, although the burden of cardiovascular mortality (CVM) in such patients remains unknown. We conducted a retrospective cohort study of patients greater than or equal to 20 years of age diagnosed with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) between 2000 and 2013 using data extracted from the United States Surveillance, Epidemiology, and End Results (SEER) database. Our primary endpoint was CVM. The association between NHL and CVM was evaluated using multivariable Cox regression analysis after adjusting for other patient characteristics. We calculated standardized mortality ratios (SMRs) for CVM, comparing NHL patients with the general population. We identified 153 983 patients who met the inclusion criteria (69 329 with DLBCL, 48 650 with CLL/SLL, and 36 004 with FL). The median follow-up was 37 months (interquartile range, 10-78 months); the mean patient age was 66.24 (±14.69) years; 84 924 (55.2%) were men; 134 720 (87.5%) were White, and 131 912 (85.7%) did not receive radiation therapy. Overall, 9017 patients (5.8%) died from cardiovascular disease, and we found that NHL patients had a higher risk of CVM than the general population, after adjusting for age (SMR 15.2, 95% confidence interval: 14.89-15.52). The rates of CVM were 5.1%, 8%, and 4.4% in patients with DLBCL, CLL/SLL, and FL, respectively. Furthermore, across all NHL subtypes, older age, higher stage at the time of diagnosis (particularly stage 4), male sex, and living in the south were associated with higher risks of CVM. Our data suggest that risk assessment and careful cardiac monitoring are recommended for NHL patients, particularly those with the CLL/SLL subtypes.

Marital status and 5-year mortality: A population-based prospective cohort study

OBJECTIVES

The aim was to investigate the association between baseline marital status and mortality using survival (Cox-regression) analysis.

STUDY DESIGN

This is a prospective cohort study.

METHODS

The public health survey by Scania in 2008 was linked to the Swedish cause of death register. This prospective cohort study includes 12,245 men and 14,969 women aged 18-80 years, and 538 men and 362 women of them died during the 5.3-year follow-up.

RESULTS

Unmarried, divorced, and widowed men had significantly higher hazard rate ratios (HRRs) of all-cause mortality than married/cohabitating men. For women, the HRRs of these groups did not significantly differ from those of the married/cohabitating reference group.

CONCLUSIONS

The results are in accordance with a previous study that only compared those living alone with those cohabitating.

The parental co-immunization hypothesis: An observational competing risks analysis

The main interest of this study is the hypothesis that contact with small children may be beneficial for the parents’ later health and mortality (because of changes in their immune system). For this purpose, we document the relationship of a set of individual characteristics—including parenthood and marital state—and socioeconomic status with an individual’s cause of death. Using a novel and rich data set made available by the Office for National Statistics Longitudinal Study (ONS-LS), which follows 1% of the population of England and Wales along five census waves 1971, 1981, 1991, 2001, and 2011, our competing risks analysis yields several striking results: (1) Females with children have a 72.5% reduced risk of dying of cancer compared to childless females (for childless females of age 70, this corresponds to a risk of dying of cancer of 1.3% compared to a risk of about 1.3 × 0.275 = 0.4% for females with children). (2) Males have a 171% increased chance of dying of cancer when they are married (e.g., a baseline probability of 1.2% when 75 year old) compared to unmarried males. (3) Females with children have only a 34% risk of dying of heart disease (corresponding to a conditional probability of 0.3% when aged 65) relative to females without children and (4) a 53% chance of dying of infections (i.e., 0.1% at 65 years of age) compared to the risk for females without children. (5) At the same age, married men have an increased expectation of 123% of dying of heart disease (corresponding to an expected death probability of 0.7%) compared to unmarried men. (6) High income and house ownership is always associated with higher survival but less so than having children. While these results document a relationship between the presence of children and mortality, the specific transmission mechanisms remain unclear and we cannot make causality assertions.

No association between tumor laterality and cardiac-related mortality in breast cancer patients after radiotherapy: a population-based study

Introduction

To assess the effect of tumor laterality to cardiac-related deaths of breast cancer in the current radiation practices using a large modern population-based study.

Methods

Women diagnosed with breast cancer from 2000 to 2008 were included using the current Surveillance, Epidemiology, and End Results database. The primary outcome of this study was the cardiac-related mortality. Multivariate analysis was performed using the Cox proportional hazards model to analyze the cardiac-related mortality including demographic, clinicopathologic, and treatment factors.

Results

We identified 168,761 breast cancer patients, including 85,006 (50.4%) patients with left-sided tumors and 83,755 (49.6%) patients with right-sided tumors. The median follow-up period was 8.8 years. The 10-year cardiac-related mortality was 2.3% and 2.3% in left- and right-sided tumors, respectively (P=0.685). The results indicated that patients with older age, non-Hispanic Black, receipt of mastectomy, and married status were the independent adverse factors for cardiac-related mortality. However, left-sided tumors were not associated to a higher risk of cardiac-related mortality than right-sided tumors following postoperative radiotherapy (right vs left, hazard ratios 1.025, 95% CI 0.856–1.099, P=0.484). The risk of cardiac-related mortality in the entire cohort was increased with the extension of follow-up time. However, there was still not significantly different between left- and right-sided tumors. Subgroup analysis also found no association between tumor laterality and cardiac-related mortality after postoperative radiotherapy based on various demographics and treatment factors.

Conclusion

With a median follow-up of 8.8 years, no significant differences were found in cardiac-related mortality between left- and right-sided tumors under current radiation practices of breast cancer patients.

Factors influencing change in walking ability in patients with heart failure undergoing exercise-based cardiac rehabilitation

OBJECTIVES

Exercise-based cardiac rehabilitation (CR) is an effective intervention for patients with heart failure (HF), in which one of the main targets is to increase physical capacity. In the HF population this is traditionally assessed using distance covered during a walking test. This study aims to establish the extent to which change in walking ability, in HF patients attending CR, is determined by patient characteristics and service provision.

METHODS

The study utilised routine clinical data from the National Audit of Cardiac Rehabilitation to perform a robust analysis. Change, in metres, between pre- and post-CR six-minute walk tests was calculated. Multivariate linear regression models were used to explore the relationship between patient characteristics, service-level variables, and change in metres walked.

RESULTS

Complete and valid data from 633 patients was analysed, and a mean change of 51.30 m was calculated. Female gender (-34.13 m, p = 0.007), being retired (-36.41 m, p = 0.001) and being married/in a relationship (-32.54 m, p = 0.023) were all significant negative predictors of change. There was an additional negative relationship with body mass index (BMI) whereby for every unit increase in BMI, predicted change reduces by 2.48 m (p = 0.006).

CONCLUSIONS

This study identified significant patient-level characteristics strongly associated with limited improvement in walking ability following CR. Improving physical capacity is a core component of CR, therefore services should aim to account for baseline characteristics identified in this study as part of tailoring the CR intervention around the individual. Pre- and post-CR physical capacity assessments, which constitute minimum standards for CR, are worryingly low and should be given high priority.

Partnership trajectories and cardiovascular health in late life of older adults in England and Germany

Objectives

Previous studies have shown marital status differences in incidence and prevalence of cardiovascular disease and cardiovascular mortality. This study examines the consequences of partnership on biomarkers related to cardiovascular health of older men and women in Germany and England (C-reactive protein, HbA1c, systolic and diastolic blood pressure; and total cholesterol).

Methods

Data used is from older adults (60 +) from the German Survey of Health and Retirement Europe SHARE (n=955) and the English Longitudinal Study of Ageing ELSA (n=9707). Life course partnership is measured using the timing (age at first partnership), quantum (number of partnerships) and partnership trajectory. OLS for C-reactive protein, logistic regressions for systolic and diastolic blood pressure, and multinomial logistic regressions for cholesterol are used to investigate the associations between life course partnership characteristics and biomarkers, accounting for early age socioeconomic and health conditions.

Results

Timing of first partnership is associated with poor cardiovascular health in England, number of partnership transitions with poor health in Germany, and partnership trajectories are associated with cardiovascular health both in Germany and England. Men in trajectories with multiple marriages have higher CRP, and are more likely to have elevated systolic and diastolic BP. Trajectories containing single marital disruption for men and women are no longer associated with poor health after accounting for selection effects of childhood conditions. Respondents in widowed partnership trajectories have poorer cardiovascular health compared to those in intact committed relationships, whereas cohabitation trajectories do not differ in the associations with biomarkers from those in intact marriage.

Conclusion

The results offer better understanding of the pathways through which family events and processes are linked to health and support the hypothesis that adversity related to partnerships over the life course accumulates and contributes to worse cardiovascular health in later life measured by objective health measures.

•

This study investigates the longitudinal accumulated effects of partnership on cardiovascular health using haemostatic and inflammatory biomarkers in later-life, C-reactive protein, HbA1c, systolic and diastolic blood pressure; and total cholesterol.

•

Based on life course theory of cumulative disadvantage, the study finds support that the benefits and risks of marital status accumulate over the life-course. The effects are visible on biomarkers of older adults in both Germany and England in models that account for conditions in early life, health behaviors in adult life and sociodemographic factors.

•

Data used is from older adults (60 +) form the German Survey of Health and Retirement Europe SHARE (n=955) and the English Longitudinal Study of Ageing ELSA (n=9707). Life course partnership is measured using the timing (age at first partnership), quantum (number of partnerships) and partnership sequence type.

Marital status and risk of cardiovascular diseases: a systematic review and meta-analysis

BACKGROUND

The influence of marital status on the incidence of cardiovascular disease (CVD) and prognosis after CVD is inconclusive. We systematically reviewed the literature to determine how marital status influences CVD and prognosis after CVD.

METHODS

A search of MEDLINE and Embase in January 2018 without language restriction was performed to identify studies that evaluated the association between marital status and risk of CVD. Search terms related to both marital status and CVD were used and included studies had to be prospective in design. The outcomes of interest were CVD, coronary heart disease (CHD) or stroke incidence and mortality. We performed random effects meta-analysis stratified by the types of population by calculating odds ratios (OR) and 95% confidence intervals (95% CI).

RESULTS

Our analysis included 34 studies with more than two million participants. Compared with married participants, being unmarried (never married, divorced or widowed) was associated with increased odds of CVD (OR 1.42; 95% CI 1.00 to 2.01), CHD (OR 1.16,95% CI 1.04 to 1.28), CHD death (OR 1.43,95% CI 1.28 to 1.60) and stroke death (OR 1.55,95% 1.16 to 2.08). Being divorced was associated with increased odds of CHD (P<0.001) for both men and women while widowers were more likely to develop a stroke (P<0.001). Single men and women with myocardial infarction had increased mortality (OR 1.42, 95% CI 1.14 to 1.76) compared with married participants.

CONCLUSIONS

Marital status appears to influence CVD and prognosis after CVD. These findings may suggest that marital status should be considered in the risk assessment for CVD and outcomes of CVD based on marital status merits further investigation.

Associations of the lipid genetic variants Thr54 ( FABP2) and -493T ( MTTP) with total cholesterol and low-density lipoprotein cholesterol levels in Mexican subjects

Objective Mexico has one of the world's highest rates of obesity, which is influenced by lipid-genetic and lifestyle factors. This study aimed to determine whether FABP2 (Ala54Thr) and MTTP (-493 G/T) genetic polymorphisms are associated with metabolic disorders in Mexican subjects. Methods A total of 523 subjects participated in a cross-sectional study. Genotyping for FABP2 and MTTP was performed using real-time RT-PCR. Biochemical and anthropometric data were evaluated. Results The genetically at-risk group (Thr54/-493T) was associated with significantly higher total and low-density lipoprotein cholesterol levels (difference between genetically at-risk group and wild-type group: 10.6 mg/dL and 8.94 mg/dL, respectively). Carriers within the genetically at-risk group had a significantly higher prevalence rate of hypercholesterolaemia (42.5% vs. 32.0%) and higher LDL-C levels (37.6% vs. 26.4%) than did non-carriers. Conclusions Subjects who are genetically at risk (Thr54/-493T) have higher total cholesterol levels, low-density lipoprotein cholesterol levels, and prevalence rate of hypercholesterolaemia. These findings highlight the importance of basing nutritional intervention strategies for preventing and treating chronic diseases on individual genetic characteristics.

Impact of marital status and comorbid disorders on health-related quality of life after cardiac surgery

PURPOSE

To explore associations between HRQL, marital status, and comorbid disorders in men and women following cardiac surgery.

METHOD

A secondary analysis was completed using data from a randomized controlled trial in which 416 individuals (23% women) scheduled for elective coronary artery bypass graft and/or valve surgery were recruited between March 2012 and September 2013. HRQL was assessed using the Health State Descriptive System (15D) preoperatively, then at 2 weeks, and at 3, 6, and 12 months following cardiac surgery. Linear mixed model analyses were performed to explore associations between HRQL, social support, and comorbid disorders.

RESULTS

The overall 15D scores for the total sample improved significantly from 2 weeks to 3 months post surgery, with only a gradual change observed from 3 to 12 months. Thirty percent (n = 92) of the total sample reported a lower 15D total score at 12 months compared to preoperative status, of whom 78% (n = 71) had a negative minimum important differences (MID), indicating a worse HRQL status. When adjusted for age and marital status, women had statistically significant lower 15D total scores compared to men at 3, 6, and 12 months post surgery. Compared to pre-surgery, improvement was demonstrated in 4 out of 15 dimensions of HRQL for women, and in 6 out of 15 dimensions for men at 12 months post surgery. Both men and women associated back/neck problems, depression, and persistent pain intensity with lower HRQL; for women, not living with a partner/spouse was associated with lower HRQL up to 12 months.

CONCLUSION

Women experienced decreased HRQL and a slower first-year recovery following cardiac surgery compared to men. This study demonstrates a need for follow-up and support to help women manage their symptoms and improve their function within the first year after cardiac surgery. This was particularly pronounced for those women living alone.
