Self-reported economic difficulties and coronary events in men: evidence from the Whitehall II study

The Percentage of Patients Experiencing Financial Strain Depends on the Screening Measure: Evidence From a Cross-Sectional Survey of Adult Members of an Integrated Healthcare Delivery System

OBJECTIVES

Financial strain has important consequences for patients, providers, and health care systems. However, there is currently no gold standard measure to screen for financial strain. This study compared the performance of 3 single-item screeners using a composite measure of financial strain as a "gold standard."

METHODS

We conducted a secondary analysis of unweighted data from a 2021 survey of Kaiser Permanente Northern California health plan members comparing the percentages of adults who experienced financial strain based on 3 general single-item screeners, a screener specific to medical and dental health care use, and a composite financial strain measure. The study sample was comprised of 2734 non-Medicaid insured adults who answered all financial strain questions. Kappa statistics evaluating agreement of the 3 general screeners with the composite measure were calculated for the sample overall, by age group, and within age group, by 4 levels of income and 4 racial/ethnic subgroups.

RESULTS

Among 947 adults aged 35 to 65, 30.7% had just enough money or not enough money to make ends meet, 23.3% had a somewhat hard or hard time paying for basics, 18.8% had trouble paying for ≥1 type of expense, 20.5% had delayed/used less medical/dental care, and 41.5% had experienced financial strain based on the composite measure. Among 1787 adults aged 66 to 85, the percentages who screened positive on these measures were 22.7%, 19.4%, 12.9%, 19.8%, and 34.4%, respectively. Across the sample, by income categories and racial/ethnic groups, the making ends meet screener identified higher percentages of adults experiencing financial strain and performed better when compared with the composite measure than the hard to pay for the very basics and trouble paying for expenses screeners. Overall, substantial decreases in the percentages of adults who screened positive on the financial strain measures were seen as level of income increased. Within income categories, middle-aged adults were more likely than older adults to have experienced financial strain based on the composite and general single-item screeners.

CONCLUSIONS

As social risk screening becomes part of the standard of care, it will be important to assess how well different brief screeners for financial strain perform with diverse patient populations.

Trends in the incidence and in-patient outcomes of acute myocardial infarction in pregnancy: Insights from the national inpatient sample

Study objective

Pregnancy-related morbidity and mortality rates in the United States are rising despite advances in knowledge, technology, and healthcare delivery. Cardiovascular disease is the leading cause of adverse pregnancy outcomes, with acute myocardial infarction (AMI) being a potential contributor to the worse outcomes in pregnancy.

Design/setting

We analyzed data from the national inpatient sample database to examine trends in the incidence and in-hospital outcomes of myocardial infarction in pregnancy from 2016 to 2020.

Participants

Using ICD-10-CM codes, we identified all admissions from a pregnancy-related encounter with a diagnosis of type 1 AMI.

Main outcome

Using the marginal effect of years, we assessed the trends in the incidence of AMI and utilized a multivariate logistic regression model to compare our secondary outcomes.

Results

Of the 19,524,846 patients with an obstetric-related admission, 3605 (0.02 %) had a diagnosis of type 1 AMI. Overall, we observed an approximately 2-fold increase in the trend of AMI from 1.4 to 2.5 per 10,000 obstetric admissions, with the highest incidence trend of 2.5 to 5.2 per 10,000 obstetric admissions seen in Black patients. Among patients diagnosed with AMI, we found significantly higher rates of in-hospital mortality (Adjusted Odds Ratio (AOR): 22.9, 12.2-42.8), cardiogenic shock (AOR:54.3, 33.9-86.6), preeclampsia (AOR: 2.2, 1.65-2.94) and spontaneous abortion (AOR:6.3, 3.71-10.6).

Conclusion

Over the 5-year period, we found increasing trends in the incidence of AMI in pregnancy, especially among Black patients. Incident AMI was also associated with worse pregnancy outcomes.

Missing data in bioarchaeology II: A test of ordinal and continuous data imputation

OBJECTIVES

Previous research has shown that while missing data are common in bioarchaeological studies, they are seldom handled using statistically rigorous methods. The primary objective of this article is to evaluate the ability of imputation to manage missing data and encourage the use of advanced statistical methods in bioarchaeology and paleopathology. An overview of missing data management in biological anthropology is provided, followed by a test of imputation and deletion methods for handling missing data.

MATERIALS AND METHODS

Missing data were simulated on complete datasets of ordinal (n = 287) and continuous (n = 369) bioarchaeological data. Missing values were imputed using five imputation methods (mean, predictive mean matching, random forest, expectation maximization, and stochastic regression) and the success of each at obtaining the parameters of the original dataset compared with pairwise and listwise deletion.

RESULTS

In all instances, listwise deletion was least successful at approximating the original parameters. Imputation of continuous data was more effective than ordinal data. Overall, no one method performed best and the amount of missing data proved a stronger predictor of imputation success.

DISCUSSION

These findings support the use of imputation methods over deletion for handling missing bioarchaeological and paleopathology data, especially when the data are continuous. Whereas deletion methods reduce sample size, imputation maintains sample size, improving statistical power and preventing bias from being introduced into the dataset.

The relationship between financial hardship and incident diabetic kidney disease in older US adults - a longitudinal study

Background

Financial hardship is associated with poor health, however the association of financial hardship and incident diabetic kidney disease (DKD) is unknown. This study aimed to examine the longitudinal relationship between financial hardship and incident DKD among older adults with diabetes.

Methods

Analyses were conducted in 2735 adults age 50 or older with diabetes and no DKD using four waves of data (2006–2012) from the Health and Retirement Study, a national longitudinal cohort. The primary outcome was incident DKD. Financial hardship was based on three measures: 1) difficulty paying bills; 2) food insecurity; and 3) cost-related medication non-adherence using validated surveys. A dichotomous financial hardship variable (0 vs 1 or more) was constructed based on all three measures. Cox regression models were used to estimate the association between financial hardship, change in financial hardship experience and incident DKD adjusting for demographics, socioeconomic status, and comorbidities.

Results

During the median follow-up period of 4.1 years, incident DKD rate was higher in individuals with versus without financial hardship (41.2 versus 27/1000 person years). After adjustment, individuals with financial hardship (HR 1.32, 95% CI 1.04–1.68) had significantly increased likelihood of developing DKD compared to individuals without financial hardship. Persistent financial hardship (adjusted HR 1.52 95% CI 1.06–2.18) and negative financial hardship (adjusted HR 1.54 95% CI 1.02–2.33) were associated with incident DKD compared with no financial hardship experience. However, positive financial hardship was not statistically significant in unadjusted and adjusted (adjusted HR 0.89 95% CI 0.55–1.46) models. Cost-related medication non-adherence (adjusted HR 1.43 95% CI 1.07–1.93) was associated with incident DKD independent of other financial hardship measures.

Conclusions

Financial hardship experience is associated with a higher likelihood of incident DKD in older adults with diabetes. Future studies investigating factors that explain the relationship between financial hardship and incident DKD are needed.

Associations between social connections, their interactions, and obesity differ by gender: A population-based, cross-sectional analysis of the Canadian Longitudinal Study on Aging

Objectives

To quantify the link between four different types of social ties and objective measures of abdominal and general obesity, and to explore their inter-relationships in association with obesity using a gender-sensitive analysis.

Methods

A cross-sectional analysis of 28,238 adults (45–85 years) from the baseline Canadian Longitudinal Study on Aging Comprehensive cohort (2012–15). Social ties (marital status, living arrangement, social network size, and social participation) and measured anthropometry (body mass index, waist circumference) were analyzed using linear and logistic regression models with interaction terms conditioned on known confounders.

Results

We found that being single, widowed or divorced/separated was associated with worse anthropometric outcomes in women, including higher odds of both abdominal and general obesity, and that associations were enhanced when combined with limited social participation, lone-living and greater social network size. Few clear associations were observed in men. Limited social participation (no social activities at least once/month) among women was associated with larger waist circumference (+4.19 cm [95% CI: 1.86, 6.52]) and higher odds of both abdominal and general obesity. By contrast, associations appeared to be reversed in men: lone-living and smaller social networks were associated with lower odds of obesity, compared to co-living and larger social networks. We also found that more regular social participation can potentially mitigate the adverse associations between non-partnership (single, divorced) and obesity in women. Overall, the combined influence of two types of social tie deficits on excess weight measures was more pronounced in women than men.

Conclusions

Results highlight the importance of considering how the role of social ties for obesity prevention may differ for women and men. Frequent social participation and number of social contacts may matter for assessing whether divorced, single or lone-living older women are at risk of obesity while living arrangement and social contacts may matter for obesity in men.

Financial strain and ideal cardiovascular health in middle-aged and older women: Data from the Women's health study

Financial strain is a prevalent form of psychosocial stress in the United States; however, information about the relationship between financial strain and cardiovascular health remains sparse, particularly in older women.

METHODS

The cross-sectional association between financial strain and ideal cardiovascular health were examined in the Women's Health Study follow-up cohort (N = 22,048; mean age = 72± 6.0 years).Six self-reported measures of financial strain were summed together to create a financial strain index and categorized into 4 groups: No financial strain, 1 stressor, 2 stressors, and 3+ stressors. Ideal cardiovascular health was based on the American Heart Association strategic 2020 goals metric, including tobacco use, body mass index, physical activity, diet, blood pressure, total cholesterol and diabetes mellitus. Cardiovascular health was examined as continuous and a categorical outcome (ideal, intermediate, and poor). Statistical analyses adjusted for age, race/ethnicity, education and income.

RESULTS

At least one indicator of financial strain was reported by 16% of participants. Number of financial stressors was associated with lower ideal cardiovascular health, and this association persisted after adjustment for potential confounders (1 financial stressor (FS): B = -0.10, 95% Confidence Intervals (CI) = -0.13, -0.07; 2 FS: B = -0.20, 95% CI = -0.26, -0.15; 3+ FS: B = -0.44, 95% CI = -0.50, -0.38).

CONCLUSION

Financial strain was associated with lower ideal cardiovascular health in middle aged and older female health professional women. The results of this study have implications for the potential cardiovascular health benefit of financial protections for older individuals.

The relationship between payer type and lipid outcomes in response to clinical lifestyle interventions in youth with dyslipidemia

BACKGROUND

Payer-type (government-sponsored health coverage versus private health insurance) has been shown to influence a variety of cardiovascular disease outcomes in adults. However, it is unclear if the payer-type impacts the response to a lifestyle intervention in children with dyslipidemia.

METHODS

We analyzed data prospectively collected from patients under the age of 25 years who were referred to a large regional preventive cardiology clinic from 2010 to 2016 in Massachusetts. We compared baseline high density lipoprotein cholesterol (HDL-C), triglycerides (TG), non-HDL-C, and low density lipoprotein cholesterol (LDL-C) by payer-type. Further, we analyzed the change in lipid values in response to a clinic-based multidisciplinary intervention over a nearly six-year period by payer-type with multi-variable adjusted linear regression models. We also tested for effect modifications by age, sex, race, and body mass index (BMI) category.

RESULTS

Of the 1739 eligible patients (mean age 13 years, 52% female, 60% overweight and obese, 59% White), we found that patients with government-sponsored coverage (n = 354, 20%) presented to referral lipid clinic with lower HDL-C (- 3.5 mg/dL [1.0], p < 0.001) and higher natural log-transformed TG (+ 0.14 [0.04], p < 0.001) as compared to those with private insurance; however, the association was attenuated to the null after additionally adjusting for BMI category (- 1.1 [0.9], p = 0.13, and + 0.05 [0.04], p = 0.2 for HDL-C and natural log-transformed TG, respectively). We found no difference in baseline LDL-C between payer-types (+ 3.4 mg/dL [3.0], p = 0.3). However, longitudinally, we found patients with private insurance and a self-reported race of White to have a clinically meaningful additional improvement in LDL-C, decreasing 12.8 (5.5) mg/dL (p = 0.02) between baseline and first follow-up, as compared to White patients with government-sponsored health coverage, after adjusting for age, sex, time between visits, and baseline LDL-C.

CONCLUSIONS

Our results suggest that youth with government-sponsored coverage are referred with poorer lipid profiles than those with private insurance, although this is largely explained by higher rates of overweight and obesity in the government-sponsored health coverage group. White patients with private insurance had substantially better improvement in LDL-C longitudinally, suggesting that higher socioeconomic status facilitates improvement in LDL-C, but is less beneficial for HDL-C and triglyceride levels.

Race, Depression, and Financial Distress in a Nationally Representative Sample of American Adults

Background: Although depression and financial distress are correlated, this association may differ for demographic groups, particularly based on race. Aim: Using a national sample of American adults, this study tested whether the association between Major Depressive Episode (MDE) and financial distress differs between African Americans and Whites. Methods: The National Survey of American Life (NSAL), 2003, enrolled 3570 African American and 891 Non-Hispanic White American adults. Demographic data (age and gender), socioeconomic position (SEP; i.e., education, employment, marital status, and income), financial distress, and 12-month MDE were measured. Logistic regression was used for data analysis. Results: In the pooled sample, 12-month MDE was associated with higher odds of financial distress, above and beyond objective SEP measures. We found MDE by race interaction on financial distress, suggesting stronger association between MDE and financial distress among African Americans, compared to Whites. Conclusions: The link between MDE and financial distress depends on race. The financial needs of African Americans with depression should be addressed. Depression screening is also needed for African Americans with financial distress.

Psychosocial stress and major cardiovascular events in patients with stable coronary heart disease

OBJECTIVES

Assess the risk of ischaemic events associated with psychosocial stress in patients with stable coronary heart disease (CHD).

METHODS

Psychosocial stress was assessed by a questionnaire in 14 577 patients (median age 65.0, IQR 59, 71; 81.6% males) with stable CHD on optimal secondary preventive therapy in the prospective randomized STABILITY clinical trial. Adjusted Cox regression models were used to assess associations between individual stressors, baseline cardiovascular risk factors and outcomes.

RESULTS

After 3.7 years of follow-up, depressive symptoms, loss of interest and financial stress were associated with increased risk (hazard ratio, 95% confidence interval) of CV death (1.21, 1.09-1.34; 1.15, 1.05-1.27; and 1.19, 1.08-1.30, respectively) and the primary composite end-point of CV death, nonfatal MI or nonfatal stroke (1.21, 1.13-1.30; 1.19, 1.11-1.27; and 1.17, 1.10-1.24, respectively). Living alone was related to higher risk of CV death (1.68, 1.38-2.05) and the primary composite end-point (1.28, 1.11-1.48), whereas being married as compared with being widowed, was associated with lower risk of CV death (0.64, 0.49-0.82) and the primary composite end-point (0.81, 0.67-0.97).

CONCLUSIONS

Psychosocial stress, such as depressive symptoms, loss of interest, living alone and financial stress, were associated with increased CV mortality in patients with stable CHD despite optimal medical secondary prevention treatment. Secondary prevention of CHD should therefore focus also on psychosocial issues both in clinical management and in future clinical trials.

Relationship between Economic Security and Self-Rated Health in Elderly Japanese Residents Living Alone

OBJECTIVES

The purpose of this study was to assess the relationship between economic security and self-rated health for elderly Japanese residents living alone.

DESIGN

A secondary analysis of a cross-sectional study.

SETTING

N City, H. Prefecture, Japan.

PARTICIPANTS

Survey questionnaires were distributed to 2,985 elderly residents living alone, aged ≥70 years, of which, 1,939 (65.0%) were returned and treated as valid responses.

MEASUREMENTS

The survey included questions about gender, age, number of years spent in N City, self-rated health, economic security, number of years spent living alone, reason for living alone, life satisfaction, cooking frequency, frequency of seeing a doctor, long-term care service usage, as well as whether they enjoyed their lives, participated in social organizations.

RESULTS

Of the respondents, 1,563 (80.6%) reported that they were economically secure, and 376 (19.4%) responded that they were insecure. The odds ratio predicting poor self-rated health for the economically insecure participants was significantly high (odds ratio: 3.19, 95%, Confidence Interval (CI): 2.53-4.02, and P < 0.001). Similarly, the adjusted odds ratio for poor self-rated health was significantly high for the economically insecure participants in multivariate analyses controlling for factors such as age, gender, cooking frequency, and social participation (adjusted odds ratio: 2.21, 95%, CI: 1.70-2.88, and P < 0.001). Furthermore, a similar trend was observed in stratified analyses based on gender and age groups.

CONCLUSION

Economic security predicted self-rated health independently of confounders, including social participation and cooking frequency, among the elderly Japanese living alone in communities.

Financial Hardship, Condomless Anal Intercourse and HIV Risk Among Men Who Have Sex with Men

The objective of this study was to examine the association between financial hardship, condomless anal intercourse and HIV risk among a sample of men who have sex with men (MSM). Users of a popular geosocial networking application in Paris were shown an advertisement with text encouraging them to complete a anonymous web-based survey (n = 580). In adjusted multivariate models, high financial hardship (compared to low financial hardship) was associated with engagement in condomless anal intercourse (aRR 1.28; 95% CI 1.08-1.52), engagement in condomless receptive anal intercourse (aRR 1.34; 95% CI 1.07-1.67), engagement in condomless insertive anal intercourse (aRR 1.30; 95% CI 1.01-1.67), engagement in transactional sex (aRR 2.36; 95% CI 1.47-3.79) and infection with non-HIV STIs (aRR 1.50; 95% CI 1.07-2.10). This study suggests that interventions to reduce financial hardships (e.g., income-based strategies to ensure meeting of basic necessities) could decrease sexual risk behaviors in MSM.

Association of financial hardship with poor sleep health outcomes among men who have sex with men

Previous studies have identified an association between socioeconomic status and sleep health. While some research has studied this association among sexual minority groups, including men who have sex with men (MSM), they exclusively focused on US-based populations. The interplay between the two in shaping sleep health has not been previously examined on populations residing outside the US. This study considers both determinants, by investigating whether financial hardship is associated with sleep health among a sample of MSM in Paris, France. Broadcast advertisements were placed on a popular geosocial-networking smartphone application for MSM to direct users in Paris to a web-based survey measuring financial hardship and five dimensions of sleep health as well as socio-demographic characteristics. Modified Poisson models with robust error variance were computed to estimate risk ratios (RRs) and 95% confidence intervals (CI) for the associations between financial hardship and the following self-reported outcomes: 1) poor sleep quality, 2) short sleep duration; and 3) sleep problems. In total, 580 respondents completed the survey. In this sample, both financial hardship and poor sleep health were common - 45.5% reported that it was extremely, very, or somewhat difficult for them to meet their monthly payments on bills (referred to as "high financial hardship") and 30.1% rated their sleep as fairly bad or very bad (referred to as "poor sleep quality"). Multivariate models revealed that, compared to participants who reported low financial hardship, those who reported high financial hardship were more likely to report poor sleep quality (aRR: 1.35, 95% CI: 1.04, 1.77), to report problems falling asleep (aRR: 1.23, 95% CI: 1.02, 1.49), and to report problems staying awake in the daytime (aRR: 3.12, 95% CI: 1.83, 5.31). Future research should investigate whether this relationship is causal and determine whether interventions to reduce financial hardships could promote sleep health among MSM.

Socioeconomic Factors and Severity of Coronary Artery Disease in Patients Undergoing Coronary Angiography: A Multicentre Study of Arabian Gulf States

INTRODUCTION

Coronary artery disease (CAD) is a leading cause of death worldwide. The association of socioeconomic status with CAD is supported by numerous epidemiological studies. Whether such factors also impact the number of diseased coronary vessels and its severity is not well established.

MATERIALS AND METHODS

We conducted a prospective multicentre, multi-ethnic, cross sectional observational study of consecutive patients undergoing coronary angiography (CAG) at 5 hospitals in the Kingdom of Saudi Arabia and the United Arab Emirates. Baseline demographics, socioeconomic, and clinical variables were collected for all patients. Significant CAD was defined as ≥70% luminal stenosis in a major epicardial vessel. Left main disease (LMD) was defined as ≥50% stenosis in the left main coronary artery. Multi-vessel disease (MVD) was defined as having >1 significant CAD.

RESULTS

Of 1,068 patients (age 59 ± 13, female 28%, diabetes 56%, hypertension 60%, history of CAD 43%), 792 (74%) were from urban and remainder (26%) from rural communities. Patients from rural centres were older (61 ± 12 vs 58 ± 13), and more likely to have a history of diabetes (63 vs 54%), hypertension (74 vs 55%), dyslipidaemia (78 vs 59%), CAD (50 vs 41%) and percutaneous coronary intervention (PCI) (27 vs 21%). The two groups differed significantly in terms of income level, employment status and indication for angiography. After adjusting for baseline differences, patients living in a rural area were more likely to have significant CAD (adjusted OR 2.40 [1.47, 3.97]), MVD (adjusted OR 1.76 [1.18, 2.63]) and LMD (adjusted OR 1.71 [1.04, 2.82]). Higher income was also associated with a higher risk for significant CAD (adjusted OR 6.97 [2.30, 21.09]) and MVD (adjusted OR 2.49 [1.11, 5.56]), while unemployment was associated with a higher risk of significant CAD (adjusted OR 2.21, [1.27, 3.85]).

CONCLUSION

Communal and socioeconomic factors are associated with higher odds of significant CAD and MVD in the group of patients referred for CAG. The underpinnings of these associations (e.g. pathophysiologic factors, access to care, and system-wide determinants of quality) require further study.

Recent relocation and decreased survival following a cancer diagnosis

OBJECTIVE

To determine the impact of recent relocation prior to a cancer diagnosis on cancer-specific outcomes.

METHODS

We identified 272,718 patients with two different entries in the Surveillance, Epidemiology, and End Results database within 3years of each other. Those who had relocated to a different county between entries were identified and we determined the risk of stage IV disease or cancer-specific mortality among relocators and non-relocators after adjusting for other patient-specific demographic and clinical factors.

RESULTS

A total of 4639 (1.7%) patients relocated to a new county within 3years prior to a second cancer diagnosis and 268,079 (98.3%) patients did not. Patients who had relocated to a new area were more likely to be diagnosed with stage IV cancer (25.2% vs. 20.8%; adjusted odds ratio=1.27; 95% confidence interval [CI], 1.18-1.37; P<0.001), and had an increased risk of 10-year cancer-specific mortality (20.9% vs. 17.9%; adjusted hazard ratio 1.26; 95% CI, 1.17-1.36; P<0.001).

CONCLUSION

These results suggest that recent relocation to a new county prior to a cancer diagnosis is associated with an increased risk of late-stage presentation and worse cancer-specific mortality.

Census tract based income level and lipid levels in urban pediatric primary care: a retrospective study

Background

Lower socioeconomic status has been associated with adverse lipid levels in adult populations. Childhood dyslipidemia is a risk factor for future cardiovascular disease. However, studies examining relationships between socioeconomic indicators and lipid levels in children are limited. To examine the relationship between income level and lipid levels in childhood.

Methods

We conducted a retrospective chart review of primary care patients, ages 2 to 18 years, who had lipid levels drawn at two large pediatric practices in Boston, MA between August 01, 2008 and August 31, 2010. Income level was determined using geocoding census tract data. Analysis was performed using t-test, Anova and Spearman correlation coefficients. BMI percentile, age, sex, race/ethnicity, and site were adjusted for on multivariate analyses.

Results

Reviewing 930 charts of patients with measured lipid levels, 730 had a valid address, no previously diagnosed lipid disorder and met other study eligibility criteria. Mean total cholesterol level did not vary by income level (low 155.5 mg/dl ±26.9, moderate 153.5 mg/dl ±30.4, middle 155.3 mg/dl ±26.6 and high income 155.5 mg/dl ±27.9; p = .87) on multivariate analysis. Income level was not related to LDL, HDL, or triglycerides.

Conclusions

In this analysis of children cared for in two urban pediatric primary practices, there was no association between income level determined by census tract and lipid levels in childhood. If confirmed in prospective investigations in other geographical locations, income level may not be a key driver of childhood lipid levels.

Socioeconomic status and cardiovascular risk in urban South Asia: The CARRS Study

BACKGROUND

Although South Asians experience cardiovascular disease (CVD) and risk factors at an early age, the distribution of CVD risks across the socioeconomic spectrum remains unclear.

METHODS

We analysed the 2011 Centre for Cardiometabolic Risk Reduction in South Asia survey data including 16,288 non-pregnant adults (≥20 years) that are representative of Chennai and Delhi, India, and Karachi, Pakistan. Socioeconomic status (SES) was defined by highest education (primary schooling, high/secondary schooling, college graduate or greater); wealth tertiles (low, middle, high household assets) and occupation (not working outside home, semi/unskilled, skilled, white-collar work). We estimated age and sex-standardized prevalence of behavioural (daily fruit/vegetables; tobacco use), weight (body mass index; waist-to-height ratio) and metabolic risk factors (diabetes, hypertension, hypercholesterolaemia; hypo-HDL; and hypertriglyceridaemia) by each SES category.

RESULTS

Across cities, 61.2% and 16.1% completed secondary and college educations, respectively; 52.8% reported not working, 22.9% were unskilled; 21.3% were skilled and 3.1% were white-collar workers. For behavioural risk factors, low fruit/vegetable intake, smoked and smokeless tobacco use were more prevalent in lowest education, wealthy and occupation (for men only) groups compared to higher SES counterparts, while weight-related risks (body mass index 25.0-29.9 and ≥30 kg/m(2); waist-to-height ratio ≥0.5) were more common in higher educated and wealthy groups, and technical/professional men. For metabolic risks, a higher prevalence of diabetes, hypertension and dyslipidaemias was observed in more educated and affluent groups, with unclear patterns across occupation groups.

CONCLUSIONS

SES-CVD patterns are heterogeneous, suggesting customized interventions for different SES groups may be warranted. Different behavioural, weight, and metabolic risk factor prevalence patterns across SES indicators may signal on-going epidemiological transition in South Asia.

Financial Insolvency as a Risk Factor for Early Mortality Among Patients With Cancer

PURPOSE

Patients with cancer are more likely to file for bankruptcy than the general population, but the impact of severe financial distress on health outcomes among patients with cancer is not known.

METHODS

We linked Western Washington SEER Cancer Registry records with federal bankruptcy records for the region. By using propensity score matching to account for differences in several demographic and clinical factors between patients who did and did not file for bankruptcy, we then fit Cox proportional hazards models to examine the relationship between bankruptcy filing and survival.

RESULTS

Between 1995 and 2009, 231,596 persons were diagnosed with cancer. Patients who filed for bankruptcy (n = 4,728) were more likely to be younger, female, and nonwhite, to have local- or regional- (v distant-) stage disease at diagnosis, and have received treatment. After propensity score matching, 3,841 patients remained in each group (bankruptcy v no bankruptcy). In the matched sample, mean age was 53.0 years, 54% were men, mean income was $49,000, and majorities were white (86%), married (60%), and urban (91%) and had local- or regional-stage disease at diagnosis (84%). Both groups received similar initial treatments. The adjusted hazard ratio for mortality among patients with cancer who filed for bankruptcy versus those who did not was 1.79 (95% CI, 1.64 to 1.96). Hazard ratios varied by cancer type: colorectal, prostate, and thyroid cancers had the highest hazard ratios. Excluding patients with distant-stage disease from the models did not have an effect on results.

CONCLUSION

Severe financial distress requiring bankruptcy protection after cancer diagnosis appears to be a risk factor for mortality. Further research is needed to understand the process by which extreme financial distress influences survival after cancer diagnosis and to find strategies that could mitigate this risk.

Joint effect of education and main lifetime occupation on late life health: a cross-sectional study of older adults in Xiamen, China

Background

The effects of education and occupation on health have been well documented individually, but little is known about their joint effect, especially their cumulative joint effect on late life health.

Methods

We enrolled 14,292 participants aged 60+ years by multistage sampling across 173 communities in Xiamen, China, in 2013. Heath status was assessed by the ability to perform six basic activities of daily life. Education was classified in four categories: ‘Illiterate’, ‘Primary’, ‘Junior high school’ and ‘Senior high school and beyond’. Main lifetime occupation was also four categorized: ‘Employed’, ‘Farmer’, ‘Jobless’ and ‘Others’. Odds ratios (ORs) were estimated by random-intercept multilevel models regressing health status on education and main lifetime occupation with or without their interactions, adjusting by some covariates.

Results

Totally, 13,880 participants had complete data, of whom 12.5% suffered from disability, and ‘Illiterate’ and ‘Farmer’ took up the greatest proportion (33.01% and 42.72%, respectively). Participants who were higher educated had better health status (ORs = 0.62, 0.46, and 0.44 for the ‘Primary’, ‘Junior high school’, and ‘Senior high school and beyond’, respectively, in comparison with ‘Illiterate’). Those who were long term jobless in early life had poorest heath (ORs = 1.88, 95% CI 1.47 to 2.40). Unexpectedly, for the farmers, the risk of poor health gradually increased in relation to higher education level (ORs = 1.26, 1.28, 1.40 and 2.24, respectively). For the ‘Employed’, similar ORs were obtained for the ‘Junior high school’ and ‘Senior high school and beyond’ educated (both ORs = 1.01). For the ‘Farmer’ and ‘Jobless’, participants who were ‘Illiterate’ and ‘Primary’ educated also showed similar ORs.

Conclusions

Both education and main lifetime occupation were associated with late life health. Higher education was observed to be associated with better health, but such educational advantage was mediated by main lifetime occupation.

Economic difficulties and subsequent disability retirement

BACKGROUND

This study examined whether economic difficulties are associated with subsequent disability retirement while controlling for covariates.

METHODS

Survey data among middle-aged employees of the City of Helsinki in 2000-2002 were linked with the Finnish Centre for Pensions register data on all-cause disability retirement among women (n=4816) and men (n=1354) until the end of 2010. Additionally, disability retirement due to musculoskeletal diseases and mental disorders (ICD-10) was examined among women. Frequency in difficulties paying pills and buying food and clothes, and covariates (occupational class, income, housing tenure, and work- and health-related covariates) were self-reported at baseline. Hazard ratios (HR) and their 95% confidence intervals (95% CI) were calculated from Cox regression analysis.

RESULTS

Frequent economic difficulties were associated with all-cause disability retirement after adjusting for age among both women (HR=2.11; 95% CI 1.63-2.73) and men (HR=2.69; 95% CI 1.65-4.41). Adjustment for covariates somewhat attenuated the associations, but they remained. Economic difficulties were also associated with disability retirement due to both mental disorders (HR=3.29; 95% CI 1.98-5.46) and musculoskeletal diseases (HR=1.85; 95% CI 1.24-2.75) among women. Adjustments made a minor contribution to the risk of disability retirement due to mental disorders, whereas the risk of disability retirement due to musculoskeletal diseases reduced after considering socioeconomic circumstances. Conclusions: economic difficulties are independently associated with disability retirement. Thus, they should be considered in attempts to tackle early exit from the labour market due to disability.

Persistent financial hardship, 11-year weight gain, and health behaviors in the Whitehall II study

OBJECTIVE

To ascertain prospectively gender-specific associations between types and amounts of financial hardship and weight gain, and investigate potential behavioral mechanisms.

METHODS

Prospective study of 3701 adult British civil servants with repeated measures of difficulty paying bills or insufficient money to afford adequate for food/clothing (1985-1988; 1989-1990; 1991-1993; 1997-1999), and weight (1985-1988; 1997-1999).

RESULTS

Persistent hardships were associated with adjusted mean weight change in women over 10.9 years, but no consistent pattern was seen in men. During follow-up, 46% of women gained ≥5 kg. Women reporting persistent insufficient money for food/clothing had a significantly greater odds of gaining ≥5 kg (1.42 [1.05, 1.92]) compared to no hardship history, which remained after socioeconomic status (SES) adjustment (1.45 [1.05, 2.01]). The association between persistent difficulty paying bills and odds of excess weight gain was also significant (1.42 [1.03, 1.97]) but attenuated after considering SES (1.39 [0.98, 1.97]). Four health behaviors as single measures or change variables did not attenuate associations.

CONCLUSIONS

Results suggested strategies to tackle obesity must address employed women's everyday financial troubles which may influence weight through more biological pathways than classical correlates of economic disadvantage and weight.

Socioeconomic status, financial hardship and measured obesity in older adults: a cross-sectional study of the EPIC-Norfolk cohort

Background

Socioeconomic status is strongly associated with obesity. Current economic circumstances are also independently associated with self-reported weight status in Finnish civil servants. We aimed to examine three types of financial hardship in relation to measured general and central obesity in a general population of older adults, while considering conventional socioeconomic indicators.

Methods

Data from 10,137 participants (≥50 years) in the EPIC-Norfolk cohort who responded to a postal Health and Life Experiences Questionnaire (1996–2000) and attended a clinical assessment (1998–2002). Multivariable logistic regression models assessed likelihood of general obesity (BMI ≥30 kg/m²) and central obesity (women: ≥88 cm; men: ≥102 cm) calculated from measured anthropometrics.

Results

Obesity prevalence was consistently patterned by standard socioeconomic indicators, with over-50s in the lowest social class being twice as likely to be obese than those in the highest class (women OR 2.10 [CI95: 1.41—3.13]; men OR 2.36 [1.44—3.87]). After adjustment for socioeconomic status, reporting having less than enough money for one’s needs (compared to more than enough) was associated with obesity in women (OR 2.04 [1.54—2.69]) and men (OR 1.83 [1.34—2.49]). Similar associations were demonstrated between obesity and always or often not having enough money for food/clothing (women OR 1.40 [1.03—1.90]; men OR 1.81 [1.28—2.56]), compared to reporting this never occurred. The strongest independent associations were seen for obesity and reported greatest level of difficulty paying bills (women OR 2.20 [1.37—3.55]; men 2.40 [1.38—4.17]), compared to having no difficulties. Findings for central obesity were slightly higher in women and lower in men.

Conclusions

Obesity in British over-50s was more likely in study participants who reported greater financial hardship, even after education, social class and home ownership were taken into account. Public health policies need to consider the hitherto neglected role of financial hardship in older people, especially difficulty paying bills, as part of strategies to prevent or reduce obesity.

Gender-stratified models to examine the relationship between financial hardship and self-reported oral health for older US men and women

OBJECTIVES

We evaluated the relationship between financial hardship and self-reported oral health for older men and women.

METHODS

We focused on adults in the 2008 Health and Retirement Study (n = 1,359). The predictor variables were 4 financial hardship indicators. We used Poisson regression models to estimate the prevalence ratio of poor self-reported oral health.

RESULTS

In the non-gender-stratified model, number of financial hardships was not significantly associated with self-reported oral health. Food insecurity was associated with a 12% greater prevalence of poor self-reported oral health (95% confidence interval [CI] = 1.04, 1.21). In the gender-stratified models, women with 3 or more financial hardships had a 24% greater prevalence of poor self-reported oral health than women with zero (95% CI = 1.09, 1.40). Number of hardships was not associated with self-reported oral health for men. For men, skipping medications was associated with 50% lower prevalence of poor self-reported oral health (95% CI = 0.32, 0.76).

CONCLUSIONS

Number of financial hardships was differentially associated with self-reported oral health for older men and women. Most financial hardship indicators affected both genders similarly. Future interventions to improve vulnerable older adults' oral health should account for gender-based heterogeneity in financial hardship experiences.

Changes in economic difficulties and subsequent sickness absence: a prospective register-linkage study

OBJECTIVES

People's economic difficulties are associated with their health, but consequences of changes in economic difficulties are less understood. We aimed to examine the associations between changes in economic difficulties and subsequent sickness absence while considering socioeconomic circumstances and other covariates.

DESIGN

A prospective cohort study.

SETTING

Helsinki, Finland.

PARTICIPANTS

Municipal employees of the City of Helsinki, Finland (n=3859), who were respondents to the baseline (2000-2002) and follow-up (2007) questionnaire surveys and had register-based follow-up data on sickness absence until the end of 2010.

PRIMARY AND SECONDARY OUTCOME MEASURES

Self-certified short (1-3 days) and medically certified intermediate (4-14 days) and long (15+ days) sickness absence spells were examined using employer's personnel register data.

RESULTS

Persistent frequent economic difficulties predicted short (rate ratios (RR) 1.66 95% CI 1.49 to 1.86), intermediate (RR 2.13 95% CI 1.85 to 2.45) and long (RR 2.18 95% CI 1.75 to 2.70) sickness absence spells. Increasing economic difficulties similarly predicted sickness absence spells. The risks were somewhat stronger the longer the absence, and remained although attenuated somewhat after full adjustment. Weak risks were found also for persistent occasional economic difficulties and decreasing economic difficulties, and they attenuated further after full adjustments.

CONCLUSIONS

Changes in economic difficulties predict subsequent sickness absence even after considering income, baseline health and other covariates. Thus economic difficulties should be considered when addressing causes of sickness absence.

Rural-urban disparities in the prevalence of diabetes and coronary heart disease

OBJECTIVES

To examine the rural-urban differences in the prevalence of diabetes and coronary heart disease, and the extent to which they are explained by the presence of established risk factors including poverty.

STUDY DESIGN

Cross-sectional study of more than 214,000 respondents using data from the US Centers for Disease Control and Prevention's (CDC's) 2008 Behavioral Risk Factor Surveillance System.

METHODS

Logistic regression models were utilized; prevalence odds ratios with corresponding confidence intervals and P-values are provided.

RESULTS

The crude prevalence rates of diabetes and coronary heart disease were 8.6% (P = 0.001) and 38.8% (P < 0.001) higher among respondents living in rural areas compared with urban areas, respectively. The higher prevalence in rural areas of many of the common risk factors for these conditions, including poverty (P < 0.001), obesity (P < 0.001) and tobacco use (P < 0.001), may contribute to these findings. After controlling for these and other risk factors, the prevalence of diabetes was lower among respondents living in rural areas [prevalence odds ratio (POR) = 0.94, P = 0.032], but the prevalence of coronary heart disease was higher (POR = 1.09, P = 0.011).

CONCLUSIONS

The higher prevalence of diabetes and coronary heart disease in rural populations in the USA presents a formidable public health challenge. It exacerbates many of the pre-existing rural health disparities, including a lack of access to financial resources and primary care providers.

Economic difficulties and subsequent sleep problems: evidence from British and Finnish occupational cohorts

Background

Social determinants of sleep may prove to be as important as health status. In this study we examined the extent to which persistent and changing economic difficulties are associated with sleep problems in two prospective occupational cohorts.

Methods

We used data from Finnish (baseline 2000–2002; follow-up 2007; n = 6328) and British (baseline 1997–1999; follow-up 2003–2004; n = 5002) public sector employees. Economic difficulties, sleep problems, and a variety of covariates were assessed at baseline and follow-up.

Results

Prevalence of frequent sleep problems at follow-up was 27% and 20% among women and men in the Finnish cohort, and 34% and 27% in the British cohort, respectively. Odds for sleep problems were higher among those with persistent economic difficulties (frequent economic difficulties at baseline and follow-up) compared to those with no difficulties. This association remained after multiple adjustments, including parental and current socioeconomic position, in the Finnish (OR 1.72, 95% CI 1.35–2.18) cohort. Increases in economic difficulties were similarly associated with sleep problems in the Finnish and the British cohort.

Conclusion

Evidence from two occupational cohorts suggests strong associations between economic difficulty and poor sleep. Awareness of this association will help health care professionals identify and prevent sleep problems.

Financial Strain Is Associated with Malnutrition Risk in Community-Dwelling Older Women

This study examined the relationship between financial strain, or difficulty acquiring necessities, and malnutrition risk in a community dwelling sample of frail and nonfrail women aged 70-79 in the Women's Health and Aging Study (n = 679). Malnutrition risk was measured with a modified version of the Mini-Nutritional Assessment Short Form (MNA-SF) and defined as a score <11, financial strain was measured by (1) sufficiency of money on a monthly basis and (2) adequacy of income for food, and income was measured by ordinal categories. Mean (SD) modified MNA-SF score was 12.2 (1.80), and 14.7% of women had malnutrition risk. Women who usually did not have enough money to make ends meet had more than four-fold increased odds of malnutrition risk (OR = 4.54; 95% CI: 2.26, 9.14) compared to their counterparts who had some money left over each month. This was only slightly attenuated after control for income and education, (OR = 4.08; 95% CI: 1.95, 8.52) remaining robust. These results show an association between financial strain and malnutrition risk, independent of income, in older women. Self-reported financial strain may be preferable to income as a screener for malnutrition risk in older adults in clinical and research settings.

Stress and the social determinants of maternal health among Puerto Rican women: a CBPR approach

This qualitative research project explores how poverty, the built environment, education, working conditions, health care access, food insecurity and perceived discrimination are experienced by Puerto Rican Latinas through the course of their lives. Five focus groups were conducted with the primary objective of documenting community experiences and perspectives regarding: 1) stress, including perceived discrimination based on race/ethnicity (racism); 2) the impact of stress on Puerto Rican women of reproductive age, their families, and/or their community; and 3) stressors that affect maternal health. Focus groups were conducted in English and Spanish in the two cities with the highest rates of premature birth and low infant birthweight in the state of Connecticut. Focus group findings indicate that participants perceived poverty, food insecurity, lack of access to quality education, and unsafe environments as significant life stressors affecting maternal and child health.

Economic strain and well-being in late life: findings from an 18-year population-based Longitudinal Study of older Taiwanese adults

BACKGROUND

This study estimates the concurrent and longitudinal effects of perceived economic strain and socioeconomic status (SES) on well-being of older adults in Taiwan.

METHODS

This study uses data from the Taiwan Longitudinal Study on Aging, a nationally representative sample (n= 3602) of older adults aged 60 and above. Participants were interviewed and followed for 18 years. Individual well-being is measured by self-reported life satisfaction, psychological distress and perceived health status. Generalized linear modeling with the generalized estimating equation estimates is used to predict the relationships between perceived economic strain, SES and well-being cross-sectionally and longitudinally, controlling for individual background characteristics, physical health and survival status.

RESULTS

Older adults who experienced economic strain had significantly poorer well-being in comparison to older adults without strain, both cross-sectionally and longitudinally, controlling for SES and other covariates. In contrast, SES indicators did not consistently predict well-being in the cross-sectional and longitudinal analyses.

CONCLUSIONS

These findings suggest a strong, cumulative, negative effect of perceived economic strain on well-being among older adults. Health-care initiatives aiming at promoting well-being among older adults should consider the impact of economic strain, which may increase at the end of the life course and threaten health and functioning.

Household income and cardiovascular disease risks in U.S. children and young adults: analyses from NHANES 1999-2008

OBJECTIVE

To assess the cardiovascular risk profile of youths across socioeconomic groups in the U.S.

RESEARCH DESIGN AND METHODS

Analysis of 1999-2008 National Health and Nutrition Examination Surveys (NHANES) including 16,085 nonpregnant 6- to 24-year-olds to estimate race/ethnicity-adjusted prevalence of obesity, central obesity, sedentary behaviors, tobacco exposure, elevated systolic blood pressure, glycated hemoglobin, non-HDL cholesterol (non-HDL-C), and high-sensitivity C-reactive protein according to age-group, sex, and poverty-income ratio (PIR) tertiles.

RESULTS

Among boys aged 6-11 years, 19.9% in the lowest PIR tertile were obese and 30.0% were centrally obese compared with 13.2 and 21.6%, respectively, in the highest-income tertile households (P(obesity) < 0.05 and P(central obesity) < 0.01). Boys aged 12-17 years in lowest-income households were more likely than their wealthiest family peers to be obese (20.6 vs. 15.6%, P < 0.05), sedentary (14.8 vs. 9.3%, P < 0.05), and exposed to tobacco (19.0 vs. 6.5%, P < 0.01). Compared with girls aged 12-17 years in highest-income households, lowest-income household girls had higher prevalence of obesity (17.9 vs. 13.1%, P < 0.05), central obesity (41.5 vs. 29.2%, P < 0.01), sedentary behaviors (20.4 vs. 9.4%, P < 0.01), and tobacco exposure (14.1 vs. 5.9%, P < 0.01). Apart from higher prevalence of elevated non-HDL-C among low-income women aged 18-24 years (23.4 vs. 15.8%, P < 0.05), no other cardiovascular disease risk factor prevalence differences were observed between lowest- and highest-income background young adults.

CONCLUSIONS

Independent of race/ethnicity, 6- to 17-year-olds from low-income families have higher prevalence of obesity, central obesity, sedentary behavior, and tobacco exposure. Multifaceted cardiovascular health promotion policies are needed to reduce health disparities between income groups.

Socioeconomic status and risk of acute myocardial infarction. Population-based case-control study

INTRODUCTION AND OBJECTIVES

Socioeconomic status is associated with cardiovascular mortality. The aims of this study were to investigate the association between socioeconomic status and its various indicators and the risk of acute myocardial infarction (AMI), and to determine whether any association found is independent of the presence of cardiovascular risk factors (CVRFs).

METHODS

Study cases were matched with controls by age, sex and year of recruitment. Cases were recruited from a hospital register and controls from cross-sectional studies of the general population. The socioeconomic status was determined from educational level and social class, as indicated by occupation. Self-reported data were collected on the presence of CVRFs.

RESULTS

The study included 1369 cases and controls. Both educational level and social class influenced AMI risk. Among non-manual workers, there was an inverse linear relationship between educational level and AMI risk independent of CVRFs: compared with university educated individuals, the odds ratio (OR) for an AMI among those with a high school education was 1.63 (95% confidence interval [CI], 1.16-2.3), and among those with an elementary school education, 3.88 (95% CI, 2.79-5.39). No association between educational level and AMI risk was observed in manual workers. However, the AMI risk was higher in manual workers than non-manual university educated workers: in those with an elementary school education, the increased risk (OR=2.09; 95% CI, 1.59-2.75) was independent of CVRFs.

CONCLUSIONS

An association was found between socioeconomic status and AMI risk. The AMI risk was greatest in individuals with only an elementary school education, irrespective of CVRFs and social class, as indicated by occupation.

Economic difficulties and physical functioning in Finnish and British employees: contribution of social and behavioural factors

BACKGROUND

Childhood and current economic difficulties are associated with physical health. However, evidence concerning the factors underlying these associations is sparse. This study examines the contribution of a range of social and behavioural factors to associations between economic difficulties and physical functioning.

METHODS

We used comparable data on middle-aged white-collar employees from the Finnish Helsinki Health Study cohort (n = 3843) and the British Whitehall II Study cohort (n = 3052). Our health outcome was physical functioning measured by the SF-36 Physical Component Summary. Relative indices of inequality (RII), calculated using logistic regression analysis, were used to examine associations between economic difficulties and physical functioning, and the contribution of further socio-economic circumstances, health behaviours, living arrangements and work-family conflicts to these associations.

RESULTS

In age-adjusted models, childhood (RII = 1.76-3.06) and current (RII = 1.79-3.03) economic difficulties were associated with poor physical functioning in both cohorts. Further adjusting for work-family conflicts attenuated the associations of current economic difficulties with physical functioning in both cohorts, and also those of childhood economic difficulties in the Helsinki cohort. Adjustments for other socio-economic circumstances also caused some attenuation, while health behaviours and living arrangements had small or negligible effects.

CONCLUSIONS

Conflicts between work and family contribute to the associations of economic difficulties with physical functioning among employees from Finland and Britain. This suggests that supporting people to cope with economic difficulties, and efforts to improve the balance between paid work and family may help employees maintain good physical functioning.

Financial hardship and mortality among older adults using the 1996-2004 Health and Retirement Study

PURPOSE

We investigated the effect of financial hardship on mortality risk in a community-dwelling sample of adults 50 years of age and olderin the United States.

METHOD

The 1996 Health and Retirement Study cohorts were followed prospectively to 2004 (N = 8,377). Gender-stratified grouped Cox models were used to estimate the difference in the relative risk (RR) of mortality between a specific number of financial hardships (one, two, or three or more) and no hardships; and the predictive utility of each individual financial hardship for mortality during the follow-up period.

RESULTS

Gender-stratified models adjusted for demographics, socioeconomic characteristics, and functional limitations in 1996 showed that women reporting one (hazard ratio [HR] = 1.42; 95% confidence interval [CI]: 1.05-1.92) or three or more (HR = 1.60; 95% CI: 1.05-2.46) and men reporting two (HR = 1.80; 95% CI: 1.21-2.69) financial hardships had a substantially higher probability of mortality compared to those reporting no financial hardships. Individual financial hardships that predicted mortality in fully adjusted models for women included receiving Medicaid (HR = 2.23; 95% CI: 1.68-2.98) and for men receiving Medicaid (HR = 2.11; 95% CI: 1.57-2.84) and receiving food stamps (HR = 1.59; 95% CI: 1.09-2.33).

CONCLUSIONS

These findings suggest that over and above the influence of traditional measures of socioeconomic status, financial hardship exerts an influence on the risk of mortality among older adults and that the number and type of hardships important in predicting mortality may differ for men and women.

Health inequalities in Israel: explanatory factors of socio-economic inequalities in self-rated health and limiting longstanding illness

We examined an integrated multi-level model of psychosocial, community and behavioral factors as explanatory pathways to socio-economic inequalities in health in Israel. Using a random national sample of 1328 individuals aged 30-70 and measurements of socio-economic position (education, number of cars), health outcomes-self-rated health, limiting longstanding illness (LLI), we evaluated the contribution of psychosocial factors (stressors and psychosocial resources), community factors (individual and aggregate-level social participation and social capital) and health behaviors, to the explanation of health inequalities. Community factors contributed more than psychosocial factors or health behaviors. The integrative model provided an explanation of social inequalities in both health outcomes and a full explanation for the education-LLI association.

Social class differences in health behaviours among employees from Britain, Finland and Japan: the influence of psychosocial factors

This study aims to examine social class differences in smoking, heavy drinking, unhealthy food habits, physical inactivity and obesity, and work-related psychosocial factors as explanations for these differences. This is done by comparing employee cohorts from Britain, Finland and Japan. Social class differences in health behaviours are found in the two western European countries, but not in Japan. The studied psychosocial factors related to work, work-family interface and social relationships did not explain the found class differences in health behaviours.

The relative contributions of hostility and depressive symptoms to the income gradient in hospital-based incidence of ischaemic heart disease: 12-Year follow-up findings from the GLOBE study

There is evidence to support the view that both hostility and depressive symptoms are psychological risk factors for ischaemic heart disease (IHD), additional to the effects of lifestyle and biomedical risk factors. Both are also more common in lower socioeconomic groups. Studies to find out how socioeconomic status (SES) gets under the skin have not yet determined the relative contributions of hostility and depression to the income gradient in IHD. This has been examined in a Dutch prospective population-based cohort study (GLOBE study), with participants aged 15-74 years (n=2374). Self-reported data at baseline (1991) and in 1997 provided detailed information on income and on psychological, lifestyle and biomedical factors, which were linked to hospital admissions due to incident IHD over a period of 12 years since baseline. Cox proportional hazard models were used to study the contributions of hostility and depressive symptoms to the association between income and time to incident IHD. The relative risk of incident IHD was highest in the lowest income group, with a hazard ratio of 2.71. Men on the lowest incomes reported more adverse lifestyles and biomedical factors, which contributed to their higher risk of incident IHD. An unhealthy psychological profile, particularly hostility, contributed to the income differences in incident IHD among women. The low number of IHD incidents in the women however, warrants additional research in larger samples.

Economic difficulties and common mental disorders among Finnish and British white-collar employees: the contribution of social and behavioural factors

BACKGROUND

In addition to conventional indicators of socioeconomic position, material conditions such as economic difficulties are associated with mental health. However, there has been little investigation of these associations. This study aims to examine the association of current economic difficulties with common mental disorders (CMD) and the contribution of social and behavioural factors to this association in two cohorts of Finnish and British white-collar employees.

METHODS

Comparable survey data from the Finnish Helsinki Health Study and the British Whitehall II Study were used. CMD were measured with the GHQ-12. Inequality indices from logistic regression analysis were used to examine the association between current economic difficulties and CMD, and the contribution of other past and present socioeconomic circumstances, health behaviours, living arrangements and work-family conflicts to this association. Inequality indices show the average change in ill health for each step up in the level of economic difficulties. Analyses were conducted separately for men and women.

RESULTS

Clear associations between current economic difficulties and CMD were found. Adjusting for work-family conflicts attenuated the associations. Adjusting for indicators of past and present socioeconomic circumstances, health behaviours and living arrangements had generally negligible effects. The results were very similar among both sexes in the two cohorts.

CONCLUSIONS

Conflicts between work and family contribute to the association between economic difficulties and CMD in both Finland and Britain. Supporting people to cope not only with everyday economic difficulties but also with work-family conflicts may be important for reducing inequalities in mental health.

The impact of occupation on self-rated health: cross-sectional and longitudinal evidence from the health and retirement survey

BACKGROUND

The objective of this study is to estimate occupational differences in self-rated health, both in cross-section and over time, among older individuals.

METHODS

We use hierarchical linear models to estimate self-reported health as a function of 8 occupational categories and key covariates. We examine self-reported health status over 7 waves (12 years) of the Health and Retirement Study. Our study sample includes 9,586 individuals with 55,389 observations. Longest occupation is used to measure the cumulative impact of occupation, address the potential for reverse causality, and allow the inclusion of all older individuals, including those no longer working.

RESULTS

Significant baseline differences in self-reported health by occupation are found even after accounting for demographics, health habits, economic attributes, and employment characteristics. But contrary to our hypothesis, there is no support for significant differences in slopes of health trajectories even after accounting for dropout.

CONCLUSIONS

Our findings suggest that occupation-related differences found at baseline are durable and persist as individuals age.

Associations of multiple socio-economic circumstances with physical functioning among Finnish and British employees

BACKGROUND

To further increase our understanding of socio-economic health inequalities, we need studies considering multiple socio-economic circumstances and comparing different cultural contexts. This study compared the associations of past and present socio-economic circumstances with physical functioning between employees from Finland and Britain.

METHODS

Cross-sectional survey data from the Helsinki Health Study (n = 5866) and the Whitehall II Study (n = 3052) were used. Participants were white-collar public sector employees aged 45-60 years. Physical functioning was measured with the SF-36 physical component summary. The socio-economic indicators were parental and own education, childhood and current economic difficulties, occupational class, income, housing tenure.

RESULTS

Childhood and current economic difficulties were independently associated with physical functioning in both cohorts, although in London women childhood difficulties did not reach statistical significance. Own education was independently associated with physical functioning in Helsinki. Occupational class showed associations with physical functioning in both cohorts. These were mainly attenuated by education and income, but in London women there was a strong independent association. The association of income with physical functioning was attenuated by education (Helsinki) and occupational class (London). Parental education and housing tenure showed no consistent associations.

CONCLUSIONS

Past and present economic difficulties were independently associated with physical functioning. The conventional socio-economic indicators showed less consistent associations which were partly mediated through other indicators and modified by the national context. The associations that varied according to the indicators and between the cohorts highlight the importance of considering the multiplicity of socio-economic circumstances and comparing different cultural contexts in further studies.

Poverty, near-poverty, and hardship around the time of pregnancy

To describe income levels and the prevalence of major hardships among women during or just before pregnancy. We separately analyzed 2002-2006 population-based postpartum survey data from California's Maternal and Infant Health Assessment (n = 18,332) and 19 states participating in CDC's Pregnancy Risk Assessment Monitoring System (n = 143,452) to examine income and several hardships (divorce/separation, domestic violence, homelessness, financial difficulties, spouse/partner's or respondent's involuntary job loss or incarceration, and, in California only, food insecurity and no social support) during/just before pregnancy. In both samples, over 30% of women were poor (income </=100% of federal poverty level [FPL]) and 20% near-poor (101-200% FPL); and around 60% of low-income (poor or near-poor) women experienced at least one hardship. While hardship prevalence decreased significantly as income increased, many non-low-income women also experienced hardships; e.g., in California, 43% of all women and 13% with incomes >400% FPL experienced one or more hardships. These findings paint a disturbing picture of experiences around the time of pregnancy in the United States for many women giving birth and their children, particularly because 60% had previous births. The high prevalence of low income and of serious hardships during pregnancy is of concern, given previous research documenting the adverse health consequences of these experiences and recognition of pregnancy as a critical period for health throughout the life course. Low income and major hardships around the time of pregnancy should be addressed as mainstream U.S. maternal-infant health and social policy issues.

Use of multiple imputation in the epidemiologic literature

The authors attempted to catalog the use of procedures to impute missing data in the epidemiologic literature and to determine the degree to which imputed results differed in practice from unimputed results. The full text of articles published in 2005 and 2006 in four leading epidemiologic journals was searched for the text imput. Sixteen articles utilizing multiple imputation, inverse probability weighting, or the expectation-maximization algorithm to impute missing data were found. The small number of relevant manuscripts and diversity of detail provided precluded systematic analysis of the use of imputation procedures. To form a bridge between current and future practice, the authors suggest details that should be included in articles that utilize these procedures.

Financial strain predicts recurrent events among women with coronary artery disease

BACKGROUND

Although a number of epidemiological studies have found an association between socioeconomic status (SES) indices such as income and education and coronary morbidity and mortality, few have looked at health consequences arising from actually experiencing financial shortcomings. The objective of the present study was to examine whether financial strain predicts recurrent coronary artery disease (CAD) events among women with established CAD.

METHODS

Two hundred two women (mean age 62+/-9 years) hospitalized for an acute coronary event were followed over a period of 3.5 years. Demographic, socioeconomic, lifestyle-related, psychosocial and biological characteristics were obtained by means of questionnaires and clinical examination. Data on recurrent cardiac events were collected from the Swedish discharge and death registers.

RESULTS

Women experiencing financial strain over the past year had an increased risk for recurrent events, i.e. the combination of all-cause mortality, new acute myocardial infarction and unstable angina pectoris during the follow-up with an unadjusted hazard ratio (HR) of 3.2 (95% CI 1.6-6.6), and a HR of 2.76 (95% CI 1.02-7.50) after controlling for education, household income, age, cohabiting status, inclusion diagnosis and rehabilitation therapy. Adjustment for potential mediators, i.e. psychosocial factors, lipids, diabetes mellitus, smoking, body-mass index, blood pressure, physical activity, alcohol consumption, participation in other cardiac rehabilitation programs did not alter the results significantly.

CONCLUSIONS

Financial strain was a predictor for recurrent events among women with CAD, independently of commonly used SES indicators such as education and household income. Future studies will have to explore the mechanism behind this association.

Alcohol factors in suicide mortality rates in Manitoba

OBJECTIVE

To identify alcohol-related factors that influence mortality rates from suicide.

METHOD

We examined the impact of per capita consumption of total alcohol, spirits, beer, and wine; unemployment rate; and Alcoholics Anonymous (AA) membership rate on total, male and female suicide mortality rates in Manitoba during 1976 to 1997. Time series analyses with autoregressive integrated moving average modelling were applied to total, male and female suicide rates. The analyses performed included total alcohol consumption, spirits consumption, beer consumption, and wine consumption. Missing AA membership data were interpolated with cubic splines.

RESULTS

Total alcohol consumption, and consumption of beer, spirits, and wine individually, were significantly and positively related to female suicide mortality rates. Spirits and wine were positively related to total and male mortality rates. AA membership rates were negatively related to total and female suicide rates. Unemployment rates were positively related to male and total suicide rates.

CONCLUSIONS

The data confirm the important relations between per capita consumption measures and suicide mortality rates. Additionally, the results for AA membership rates are consistent with the hypothesis that AA membership and alcohol abuse treatment can exert beneficial effects observable at the population level.

A prospective study of change in sleep duration: associations with mortality in the Whitehall II cohort

STUDY OBJECTIVES

Although sleep curtailment has become widespread in industrialised societies, little work has examined the effects on mortality of change in sleep duration. We investigated associations of sleep duration and change in sleep duration with all-cause, cardiovascular, and non-cardiovascular mortality.

DESIGN

Prospective cohort study. Data are from baseline (Phase 1, 1985-88) and Phase 3 (1991-93), with mortality follow-up of 17 and 12 years respectively.

SETTING

The Whitehall II study of 10,308 white-collar British civil servants aged 35-55 at baseline.

PARTICIPANTS

9781 participants with complete data were included in the analyses at Phase 1, and 7729 of the same participants were included in the analyses at Phase 3 and the analyses of change in sleep duration.

INTERVENTIONS

None.

MEASUREMENTS AND RESULTS

U-shaped associations were observed between sleep (< or =5, 6, 7, 8, > or =9 hours) at Phase 1 and Phase 3 and subsequent all-cause, cardiovascular, and non-cardiovascular mortality. A decrease in sleep duration among participants sleeping 6, 7, or 8 hours at baseline was associated with cardiovascular mortality, hazard ratio 2.4 (95% confidence intervals 1.4-4.1). However, an increase in sleep duration among those sleeping 7 or 8 hours at baseline was associated with non-cardiovascular mortality, hazard ratio 2.1 (1.4-3.1). Adjustment for the socio-demographic factors, existing morbidity, and health-related behaviours measured left these associations largely unchanged.

CONCLUSIONS

This is the first study to show that both a decrease in sleep duration and an increase in sleep duration are associated with an increase in mortality via effects on cardiovascular death and non-cardiovascular death respectively.

Associations of job strain and working overtime with adverse health behaviors and obesity: evidence from the Whitehall II Study, Helsinki Health Study, and the Japanese Civil Servants Study

Adverse health behaviors and obesity are key determinants of major chronic diseases. Evidence on work-related determinants of these behavioral risk factors is inconclusive, and comparative studies are especially lacking. We aimed to examine the associations between job strain, working overtime, adverse health behaviors, and obesity among 45-60-year-old white-collar employees of the Whitehall II Study from London (n=3,397), Helsinki Health Study (n=6,070), and the Japanese Civil Servants Study (n=2,213). Comparable data from all three cohorts were pooled, and logistic regression analysis was used, stratified by cohort and sex. Models were adjusted for age, occupational class, and marital status. Outcomes were unhealthy food habits, physical inactivity, heavy drinking, smoking, and obesity. In London, men reporting passive work were more likely to be physically inactive. A similar association was repeated among women in Helsinki. Additionally, high job strain was associated with physical inactivity among men in London and women in Helsinki. In London, women reporting passive work were less likely to be heavy drinkers and smokers. In Japan, men working overtime reported less smoking, whereas those with high job strain were more likely to smoke. Among men in Helsinki the association between working overtime and non-smoking was also suggested, but it reached statistical significance in the age-adjusted model only. Obesity was associated with working overtime among women in London. In conclusion, job strain and working overtime had some, albeit mostly weak and inconsistent, associations with adverse health behaviors and obesity in these middle-aged white-collar employee cohorts from Britain, Finland, and Japan.
