PURPOSE: Self-esteem is considered to be importantly associated with both psychosocial states such as depression as well as physical health. There are no population-based studies that examine the association between self-esteem and mortality. The objective of this study was to assess whether low self-esteem was prospectively associated with increased risk of death in a population-based sample of Finnish men. METHODS: A sample of 2682 male residents of Kuopio, Finland were interviewed and followed prospectively as part of the Kuopio Ischemic Heart Disease Risk Factor Study (KIHD). Characteristics of the KIHD sample at baseline included self-esteem, measured by the Rosenberg ten-item scale, socioeconomic factors, behavioral risk factors, other psychosocial characteristics, and prevalent diseases. Mortality was ascertained through linkage to the Finnish national death registry. We assessed the relationship between self-esteem and all-cause mortality using Cox proportional hazards models. RESULTS: Low self-esteem was associated with a two-fold [hazard ratio (HR)=2.0, 95% confidence interval (CI)=1.3-3.2] increase in age-adjusted mortality. This relationship was partially explained by behavioral and socioeconomic factors, and prevalent diseases, and fully explained by other psychosocial characteristics (hopelessness, depression, cynical hostility, and sullenness). When adjusted for hopelessness alone there was no increased risk associated with low self-esteem (HR=1.3, 95% CI=0.8-2.2). CONCLUSIONS: This study found no association between self-esteem and all-cause mortality after adjustment for other psychosocial characteristics, primarily hopelessness. Our understanding of the observed relationships between some psychosocial factors and mortality may be improved by simultaneous measurement of multiple psychosocial domains, thus diminishing the potential for residual confounding.

BACKGROUND: Anemia is a common complication of advancing chronic kidney disease, yet little is known about the consistency of anemia treatment before end-stage renal disease (ESRD) and mortality on dialysis therapy. METHODS: We studied 89,193 incident Medicare patients with ESRD in 1995 to 1997 aged 67 plus years with claims 2 years before their dialysis therapy initiation. Patients were classified as follows: no epoetin, 25% or less (least consistent), greater than 25% to 50%, greater than 50% to 75%, and greater than 75% (most consistent) epoetin treatment in the available months from the first pre-ESRD epoetin dose to the first ESRD service date. Cox regression modeled the risk for 1-year death in the post-ESRD period, adjusting for age, sex, race, diabetic status, albumin level, and incidence year. RESULTS: Sixty percent of patients had hematocrits less than 30% at ESRD initiation, yet only 15.6% (N = 13,877) had epoetin claims before ESRD. The most consistent epoetin treatment group had hematocrits increase from 27.5% to 30.8% (P < 0.0001) by month 4 of treatment. Patients with the most consistent epoetin treatment had a greater mean hematocrit (29.2% +/- 0.11%; P < 0.0001) and albumin level (3.31 +/- 0.01 g/dL [33.1 g/L]) at initiation than those with the least consistent treatment (28.1% +/- 0.10% and 3.21 +/- 0.01 g/dL [32.1 g/L], respectively). The relative risk for death in patients with the least consistent versus the most consistent (the reference) epoetin treatment was 1.460 (95% CI, 1.245 to 1.713; P < 0.0001) 1 year after the first ESRD service date. CONCLUSION: Elderly patients with consistent pre-ESRD epoetin treatment had lower risks for death in the first year of dialysis therapy after ESRD initiation.

Many of the leading causes of death and disability in the United States and other countries are associated with socioeconomic position. The least well-off suffer a disproportionate share of the burden of disease, including depression, obesity, and diabetes. Research suggests that the adverse effects of economic hardship on both mental and physical health and functioning are evident at young ages and persist across the lifecourse. Moreover, these associations are seen across cultures. Data from four large epidemiologic studies on the role of psychological characteristics, social factors, and behaviors in health and disease risk are presented that highlight the striking associations between socioeconomic factors and chronic diseases. Data from these studies demonstrate that the effects of economic disadvantage are cumulative, with the greatest risk of poor mental and physical health seen among those who experienced sustained hardship over time.

OBJECTIVE: To evaluate the effect of a pharmacologically induced, temporary suppression of ovarian hormones on healthy young women's cognitive functioning. DESIGN: Sixteen healthy women with normal menstrual cycles completed the California Verbal Learning Test, a digit span test, and a verbal fluency test in the follicular phase of a normal menstrual cycle and a second time after four monthly injections of the gonadotropin-releasing hormone (GnRH) agonist. Women were randomly assigned to complete a third testing either after resuming cycles in the follicular phase or after three more injections of the GnRH agonist and while wearing an estradiol patch. The control group consisted of 10 women who were tested three times in the follicular phase of their menstrual cycles. RESULTS: Results showed no change in cognitive functioning across sessions or groups in women with suppressed ovarian function. Women who had the highest levels of menopausal symptoms when taking the GnRH agonist did not have significantly lower cognitive functioning. CONCLUSIONS: This study did not find any effect of suppression in ovarian hormones on cognitive performance of young women.

BACKGROUND: Various psychosocial factors have been linked to adult physical health and are also associated with socioeconomic position in adulthood. We evaluated the effect of socioeconomic conditions over the life course on measures of psychosocial functioning in adulthood. METHODS: Life course socioeconomic position was assessed by retrospective recall of parents' education and occupation when the respondent was age 10, and the respondents' education, occupation, and income in 2585 men from eastern Finland aged 42, 48, 54, and 60 years. Measures of psychosocial functioning were derived from scales measuring cynical hostility, hopelessness, and depressive symptoms. RESULTS: Men with both parents who had less than a primary school education or who both had unskilled manual jobs had higher age-adjusted levels of cynical hostility, hopelessness, and depressive symptoms in adulthood. Mutually adjusted analyses showed that parents' education and the respondents' education, occupation, and income all had statistically independent effects on adult levels of cynical hostility and hopelessness. For instance, men for whom neither parent had completed primary education had a 0.15 standard deviation (P = 0.006) higher cynical hostility score, and a 0.20 standard deviation (P = 0.00018) higher hopelessness score, after adjustment for education, occupation and income. In contrast, depressive symptoms in adulthood were only associated with the respondent's occupation and income. CONCLUSIONS: Childhood socioeconomic position was associated with adult psychosocial functioning, but these effects were specific to some aspects of adult psychosocial functioning--cynical hostility and hopelessness, but not depressive symptoms. Adult occupation and income were associated with all measures of psychosocial functioning. In addition to the impact of adult socioeconomic position, some aspects of poor psychosocial functioning in adulthood may also have socioeconomic roots early in life.

BACKGROUND: Comparisons of mortality outcomes between peritoneal dialysis (PD) and hemodialysis (HD) patients have shown varying results, which may be caused by the unequally distributed clinical conditions of patients at initiation. To address this issue, we evaluated the clinical characteristics of 105,954 patients at the initiation of PD and HD, using the U.S. national incidence data on treated end-stage renal disease from the Medical Evidence Form, 1995 to 1997. METHODS: A general linear model was used to analyze differences of age, albumin, creatinine, blood urea nitrogen (BUN), and hematocrit; categorical data analysis to evaluate body mass index (BMI), grouped into four categories: < 19, 19-25 (< 25), 25-30 (< 30), and 30+; and logistic regression to assess the likelihood of initiating PD versus HD. Diabetics (DM) were analyzed separately from non-diabetics (NDM). Explanatory variables in the logistic regression included incidence year, race, gender, age, BMI, albumin, creatinine, BUN, and hematocrit. Race included white and black. Age was categorized into four groups: 20-44, 45-64, 65-74, and 75+. RESULTS: At the initiation of dialysis PD patients were approximately 6 years younger (P < 0.0001) than HD patients. PD patients also had higher (P < 0.0001) albumin (+0.35 g/dL for DM and +0.23 g/dL for NDM) and hematocrit (+1.64% for DM and +1.71% for NDM) levels, and lower (P < 0.04) BUN (-8.75 mg/dL for DM and -5.24 mg/dL for NDM) and creatinine (-0.51 mg/dL for DM and -0.23 mg/dL for NDM) levels than HD patients. Whites had a higher (P < 0.0001) likelihood of starting PD than blacks, and patients with BMI <19 had a lower (P < 0.0001) chance of beginning on PD. CONCLUSION: PD patients had favorable clinical conditions at the initiation of dialysis, which should be taken into consideration when comparing dialysis outcomes between the two modalities.

BACKGROUND: Patients initiating with peritoneal dialysis (PD) have favorable clinical conditions compared with hemodialysis (HD) patients, which may contribute to the varying results found in studies of mortality across the two therapies. METHODS: National incidence data of end-stage renal disease patients from 1995 to 1997 were used, excluding the first 90 days of treatment and including all patients who were on either PD or HD on day 91. Patients were then followed for a one-year period. A Cox proportional hazards regression analysis was used, separating diabetics and non-diabetics, and two statistical models were applied. Model 1 included race, gender, age, initial modality, and incidence year as explanatory variables. Model 2 added body mass index (BMI), initial levels of serum albumin, creatinine, and blood urea nitrogen. RESULTS: Age was most highly associated with mortality, followed by biochemical variables, BMI, gender, and dialysis modality. In diabetics, the hazard ratio (HR) from Model 1 indicated no difference [1.046, 95% confidence limits (CL) 0.989-1.105; P> 0.1, HD was the reference] in mortality between PD and HD, while Model 2 demonstrated that PD patients had a 13.4% (1.134, CL 1.072-1.100, P < 0.0001) higher chance of death. In non-diabetics, hazard ratios (HRs) from Models 1 and 2 indicated that PD patients had a 23.5% (0.765, 0.722-0.812, P < 0.0001) and 11.9% (0.881, 0.30-0.935, P < 0.0001), respectively, lower likelihood of death than HD patients. CONCLUSION: Our study indicates that the results changed depending on the analytical methods used. We recommend that, due to the unequally distributed clinical conditions of patients at initiation, comparisons of mortality outcomes between dialysis modalities should be made with caution.

OBJECTIVES: To examine the influence of childhood and adult socioeconomic position, socioeconomic mobility, and cumulative disadvantage across the lifecourse on cognitive function in late middle age. METHODS: Cross-sectional population-based study of 486 men age 58 and 64 from eastern Finland. Respondent's socioeconomic position in childhood was measured using parent's education and occupation, and respondent's position in adulthood was indicated by attained education and personal income. Cognitive function was assessed using five neuropsychological tests: Trail Making, Selective Reminding, Verbal Fluency, Visual Reproduction, and the Mini-Mental State Exam. RESULTS: Each indicator of socioeconomic position made statistically independent contributions to levels of cognitive function: Respondents from poor childhood backgrounds, and those who attained a limited education and earned a low income, performed worst on each test. Men who occupied a disadvantaged socioeconomic position in childhood and then experienced upward mobility over the lifecourse exhibited better cognitive performance than those with similar socioeconomic origins but limited or no upward mobility. Conversely, men from advantaged childhood backgrounds who later in life experienced downward mobility scored poorer on each cognitive test than their counterparts who remained in the most advantaged groups throughout the lifecourse. There was a strong, graded association between cumulative socioeconomic disadvantage and cognitive function: Men who occupied a low socioeconomic position during both childhood and adulthood scored worse on every test than those who occupied a high position at all points in their lives. DISCUSSION: Socioeconomic conditions across all stages of the lifecourse appear to make unique contributions to cognitive function in late middle age. These results also suggest that in terms of cognitive function, origin is not necessarily destiny, as disadvantaged socioeconomic circumstances in childhood may be overcome to some extent by upward mobility later in life.
