Objective and subjective assessments of socioeconomic status and their relationship to self-rated health in an ethnically diverse sample of pregnant women.

A new measure of subjective socioeconomic status (SES) was examined in relation to self-rated physical health in pregnant women. Except among African Americans, subjective SES was significantly related to education, household income, and occupation. Subjective SES was significantly related to self-rated health among all groups. In multiple regression analyses, subjective SES was a significant predictor of self-rated health after the effects of objective indicators were accounted for among White and Chinese American women; among African American women and Latinas, household income was the only significant predictor of self-rated health. After accounting for the effects of subjective SES on health, objective indicators made no additional contribution to explaining health among White and Chinese American women; household income continued to predict health after accounting for subjective SES among Latinas and African American women.

A prospective study of church attendance and health over the lifespan.

Objective: The objective of the current study was to help clarify the previously ambiguous results concerning the relationship between church attendance and later physical health. Design: The current study examined the effect of church attendance on 4 different indicators of later health in a sample of inner city men followed throughout their lifecourse. Measures of previous health status, mood, substance abuse, smoking, education, and social class were used as covariates in regression analyses predicting health at age 70 from church attendance at age 47. Main outcome measures: Health at age 70 was assessed by 4 indicators: mortality, objective physical health, subjective physical health, and subjective well-being. Results: Though church attendance was related to later physical health, this was only through indirect means, as both physical health and church attendance were associated with substance use and mood. However, findings do suggest a more direct link between church attendance and well-being. Conclusion: Indirect effects of church attendance on health were clearly observed, with alcohol use/dependence, smoking, and mood being possible mediators of the church attendance-health relationship. The effects of church attendance on more subjective ratings of health, however, may be more direct. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Apolipoprotein E and Prospective Memory in Normally Aging Adults.

The ε4 allele of apolipoprotein E (APOE) is an established risk factor for Alzheimer's disease, despite uncertainty as to its effect on cognitive function in normal aging. Some evidence suggests poor episodic memory and executive functioning in ε4 allele carriers. Prospective memory has been overlooked in investigations of the relationship between APOE and cognition. The authors used a laboratory paradigm to examine the relationship between prospective memory and APOE status in healthy elderly adults, and they varied the association (high vs. low) between a target word and a response word. The authors found a significant deficit in prospective memory for ε4 allele carriers but no effect of association in either group. The results suggest the deficit was due to failure of the prospective component of the task. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality is associated with perceived health and functional status in older primary care patients.

Using data collected on 265 primary care medical patients 60 years of age and older, the authors examined the personality bases of subjective health (perceived health, functional status) after controlling for observer-rated depression and medical burden. Four hypotheses were tested: High Neuroticism is associated with poorer perceived health, low Extraversion is associated with poorer perceived health, low Openness to Experience is associated with worse functional status, and age moderates the relationships between personality and subjective health. Findings supported the notion that personality is associated with subjective health, moreover, this effect appeared to grow more pronounced with increasing age. This study underscores the conceptual and heuristic value of examining moderators of the links between personality variables and health.

Is the apolipoprotein e genotype a biomarker for mild cognitive impairment? Findings from a nationally representative study.

Objective: Although the ε4 allele of the apolipoprotein E (APOE) genotype is a known risk factor for Alzheimer's dementia (AD), prior findings on whether it is also a risk factor for mild cognitive impairment (MCI) have been inconsistent. We tested two contrasting explanations: (a) an ε4-AD specificity hypothesis, and (b) a measurement insensitivity hypothesis. Method: The frequency of the ε4 allele was investigated in older adults (mean age > 70) with various types of cognitive impairment (including MCI) and various types of dementia (including AD) with the aging, demographics, and memory study (ADAMS) of the National Institute on Aging's Health and Retirement Study (HRS). The ADAMS controls sources of Type I and Type II error that are posited in the ε4-AD specificity hypothesis and the measurement insensitivity hypothesis, and it is the only nationally representative data set on aging and cognitive impairment. Results: ε4 was a reliable predictor of MCI, with a frequency of 32% in MCI subjects versus 20% in healthy control subjects. This link was specific to MCI because ε4 was not a risk factor for other forms of cognitive impairment without dementia. Conclusions: The results support the measurement insensitivity hypothesis rather than the ε4-AD specificity hypothesis and are consistent with recent research showing modest reductions in cognitive performance among normal functioning ε4 carriers.

A mediational model of quality of life for individuals with severe mental health problems

BACKGROUND: Despite the increasing importance of quality of life in the mental health field, the theoretical conceptualization of the construct remains poorly developed. A proposed mediational model of quality of life, which links subjective quality of life with self-related constructs, is examined with a group of long-term psychiatric hostel residents. The present study aims to develop a measure of quality of life based on the proposed model, to explore the data and their implications for service development and finally to conduct a preliminary analysis of the model's predictions. METHODS: A cross-sectional research design was employed. Quality of life interviews, using a modified version of Lehman's Quality of Life Interview, were carried out with 54 psychiatric residents in Greece. The model's predictions were examined by using a series of regression analyses. RESULTS: The results indicate that perceived improvements in lifestyle, greater autonomy and positive self-concept are significantly and directly associated with better quality of life. In contrast, a direct relationship between objective indicators and subjective quality of life was not found. CONCLUSIONS: The traditional two-part quality of life model that includes objective indicators of life circumstances and subjective indicators is extended to included the constructs of self-concept and perceived autonomy. The present extended mediational model of quality of life for individuals with long-term mental health problems appears to have important implications for the planning and delivery of mental health programmes.     

Self-rated health as a predictor of ischemic heart disease development

The study objective was to analyse the association between self-rated health and the incidence of fatal and non-fatal coronary heart disease in a Danish cohort followed up over 16 years. The study included 1052 men and women born in 1936. During the 16 years' follow-up 50 cases of coronary heart disease were registered either with the Danish register of deaths or the register of hospital admissions. Univariate analysis showed the following relative risks of coronary heart disease in the four self-rated health groups: "extremely good": 1.0, "good": 4.0, "poor": 5.8, "miserable": 12.1 (p = 0.02). After control for the conventional coronary risk factors and a substantial number of other potential confounders the relative risks were: 1.0, 4.2, 6.5, and 18.6 (p = 0.02) respectively. Self-rated health was an independent predictor of coronary heart disease in this recent cohort. If confirmed, the association between self-rated health and coronary heart disease may lead to new insights into psychosocial processes leading to this disease.     

Objective and subjective socioeconomic status and susceptibility to the common cold.

Objective: We ask whether subjective socioeconomic status (SES) predicts who develops a common cold when exposed to a cold virus. Design: 193 healthy men and women ages 21-55 years were assessed for subjective (perceived rank) and objective SES, cognitive, affective and social dispositions, and health practices. Subsequently, they were exposed by nasal drops to a rhinovirus or influenza virus and monitored in quarantine for objective signs of illness and self-reported symptoms. Main Outcome Measures: Infection, signs and symptoms of the common cold, and clinical illness (infection and significant objective signs of illness). Results: Increased subjective SES was associated with decreased risk for developing a cold for both viruses. This association was independent of objective SES and of cognitive, affective and social disposition that might provide alternative spurious (third factor) explanations for the association. Poorer sleep among those with lesser subjective SES may partly mediate the association between subjective SES and colds. Conclusions: Increased Subjective SES is associated with less susceptibility to upper respiratory infection, and this association is independent of objective SES, suggesting the importance of perceived relative rank to health.

Perceived benefit and mental health after three types of disaster.

The study of growth and perceived benefit after traumatic events has been hailed as one of the most promising directions for stress research. This research, however, has been limited by several methodological limitations. These limitations are addressed in this prospective study, which examines perceived benefit and mental health adjustment after 3 different types of disaster. Survivors of a tornado in Madison, Florida, had the highest rates of perceived benefit, followed by survivors of a mass killing in Killeen, Texas, and survivors of a plane crash in Indianapolis, Indiana. Perceived benefit 4-6 weeks postdisaster predicted posttraumatic stress disorder 3 years later. Perceived benefit moderated the effect of severity of disaster exposure on mental health diagnosis change over time. Without perceived benefit, as exposure severity increased, the amount of recovery decreased. If benefit was perceived, as exposure severity increased, the amount of recovery increased. Implications for clinical interventions and future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of Apolipoprotein E Genotype on Spatial Attention, Working Memory, and Their Interaction in Healthy, Middle-Aged Adults: Results From the National Institute of Mental Health's BIOCARD Study.

The cognitive consequences of the apolipoprotein E-ε4 (APOE-ε4) allele were examined in middle age, before likely onset of symptoms of Alzheimer's disease. The authors identified 3 cognitive processes--visuospatial attention, spatial working memory, and the effect of visuospatial attention on working memory--and devised "behavioral assays" of the integrity of components of these processes. Redirecting visuospatial attention, retention of memory for location, and attentional modulation of memory of target location were affected by APOE genotype. Visuospatial attention showed additive effects of ε4 gene dose; each additional ε4 allele inherited further slowed disengagement from invalidly cued space. In contrast, working memory performance was affected only in ε4 homozygotes. Effect sizes for the APOE gene were moderate to large, ranging from 14% to 24%. Effects of APOE genotype on component processes of cognition in healthy, middle-aged adults is consistent with the emergence in adulthood of an APOE-ε4 cognitive phenotype.

The effects of physical fitness and feeling vigorous on self-rated health.

Objective: We prospectively studied the hypothesized beneficial effects of feeling vigorous and of objective physical fitness (gauged based on functional capacity) on subsequently assessed self-rated health (SRH), controlling for possible confounders known to be precursors of SRH and of our predictors. We also investigated the reverse-causation hypothesis that SRH predicts subsequent vigor and functional capacity. Design: Participants were apparently healthy employees (N = 779) who underwent a routine health check at two points of time, Time 1 (T1) and Time 2 (T2), about 18 months apart. We used regression analysis, predicting T2 SRH by T1 SRH, the control variables, and T1vigor and functional capacity. Main Outcome Measures: Vigor was assessed using the Shirom-Melamed Vigor Measure; objective physical fitness was indicated by functional capacity following a treadmill exercise, and self-rated health was measured by a single item. Results: As hypothesized, we found that the change in T2 SRH was positively predicted by T1 vigor, functional capacity, and their interactive term. Testing the reverse causation paths, we found that T1 SRH did not predict subsequent functional capacity and was a relatively weak predictor of subsequent vigor. Conclusion: The affective state of vigor and objectively assessed functional capacity interact to predict subsequent changes in self-rated health.

Clinical results and perceived health among patients with hip prosthesis

BACKGROUND: Assessment of total hip replacement has been performed without careful attention to the patients' perceived health. The objective of this study is to assess, in a standardized way, the benefit of hip replacement in terms of hip pain, mobility, and function and as an increase in general perceived health. And to quantify clinical complications of the procedure. PATIENTS AND METHODS: Observational study of a series of 131 consecutive patients of a tertiary hospital to whom two health questionnaires (one specific and the other generic) were administered before and one year after total hip replacement. The specific instrument, the Hip Pain and Function (HPF) scale, measures the functional capacity of the hip gathering information on pain, function and mobility. Scores for the HPF range from 0 (maximal limitation of functional capacity) to 85 (no limitation). The generic instrument used, the Nottingham Health Profile (NHP) measures perceived health and scores range from 0 (best health status) to 100 (worse). RESULTS: Mean age of patients was 63 years; ostheo-arthritis was the most frequent diagnosis (78%), with 42% of the patients with associated pathology. An improvement in both hip functional capacity and perceived general health was observed after one year. HPF scores increased from 26.6 at baseline to 69.9 (p < 0.001). Improvements was important and statistically significant in each of the three dimensions of the specific instrument: Pain, Function and Mobility. Overall score for the NHP changed from 50.9 (at baseline) to 18.1 (p < 0.001). Regression analysis showed only two variables associated with improvement: a higher improvement hip function for patients with no other joints affected; and a higher improvement of perceived health in patients over 70 years with cemented prosthesis, that had a worse initial perceived health status. CONCLUSION: Total hip replacement decreases pain and significantly improves hip mobility and function, as well as the general perceived health. The improvement of perceived health was higher in patients over 70 years.     

Resources for health: Differential effects of optimistic self-beliefs and social support according to socioeconomic status.

Objective: This study examined whether socioeconomic status (SES) determines the degree to which psychological and social resources such as optimistic self-beliefs and social support affect health. Design: We used data from the representative German Ageing Survey (N = 2,454, aged 40–85 years). Structural equation modeling was employed to examine whether relationships between psychological (self-esteem, control beliefs, optimism) and social resources (perceived emotional and informational support, network size) and health differ between education and income groups. Main Outcome Measures: Self-reported physical health, functional health, and subjective health. Results: Psychological resources positively affected health in all groups but were stronger predictors of functional and subjective health in low compared to higher educated participants. A higher level of social resources was associated with better functional and subjective health mainly in the low-income group. Social resources were particularly important for financially disadvantaged older people. Conclusion: Our results provide evidence for differential effects of optimistic self-beliefs and social support on health depending on whether individuals are challenged by low incomes or low education. Future research, especially aimed at intervention, should consider that different aspects of SES have differential meanings and that the impact of health-protective factors may vary according to SES facet.

Eyeblink Classical Conditioning to Auditory and Olfactory Stimuli: Performance Among Older Adults With and Without the Apolipoprotein E ε4 Allele.

Patients with Alzheimer's disease (AD) demonstrate slowed acquisition of the conditioned response (CR) in eyeblink classical conditioning paradigms (EBCC), although it is unknown how early in the course of the disease CR acquisition is affected. This study investigated whether changes in the rate of CR acquisition were apparent in nondemented older adults at greater genetic risk for developing AD (i.e., carriers of the apolipoprotein E [APOE] ε4 allele). Both ε4+ and ε4- participants demonstrated CR acquisition to auditory and olfactory CSs; however, rate of acquisition to the olfactory CS was significantly slower in ε4+ persons. Both groups acquired the CR to an auditory CS at the same rate. Results support olfactory compromise in the earliest stages of the AD disease process.

Health incongruence in later life: Implications for subsequent well-being and health care.

Objective: The premise that pessimistic health appraisals compromise well-being whereas optimistic appraisals are compensatory was examined in a longitudinal study of 232 community-dwelling older adults (ages 79-98 years). Design: Subjective health (SH) appraisals were contrasted with objective health (OH) to identify realists, whose ratings were congruent (SH = OH), distinguishing them from health pessimists (SH OH), whose ratings were incongruent. Analyses of covariance were used to examine group differences 2 years later on well-being and health care. Main Outcome Measures: Outcome measures were psychological well-being (life satisfaction, positive and negative emotions), functional well-being (objective and perceived physical activity, activity restriction), and health care (health care management, hospital admissions, length of hospital stays). Results: Compared with realists, pessimists had significantly poorer outcomes and optimists had better outcomes. Because perceived control (PC) was weaker among pessimists and stronger among optimists, supplemental analysis determined whether PC differences explained these findings. When accounting for PC, many pessimism and optimism effects became nonsignificant, yet effects on functional well-being remained unchanged. Conclusion: Findings have implications for older adults at risk of functional decline. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Apolipoprotein E and Cognitive Performance: A Meta-Analysis.

The ε4 allele of the apolipoprotein E (APOE) gene is a known risk factor for Alzheimer's disease and may also affect cognitive performance in normal aging. Evidence of the presence and magnitude of ε4-related cognitive deficits was examined with a meta-analysis of the available literature. Thirty-eight studies were included, and cognitive performance was collapsed into 8 domains. Results indicated significant APOE-ε4 group differences for global cognitive functioning, episodic memory, and executive functioning, in favor of non-ε4 carriers. In addition, older age and APOE-ε4 heterozygosity was associated with smaller ε4-related impairments. The meta-analysis results suggest that APOE-ε4 genotype does affect cognitive performance in healthy aging, although the influence is relatively small and specific to certain domains of cognitive performance.

Forty years on: Teachers' assessments of children's personality traits predict self-reported health behaviors and outcomes at midlife.

A life span health-behavior model was investigated in this longitudinal study of personality influences on health. Teachers assessed 963 elementary schoolchildren on traits that formed scales assessing the dimensions of the five-factor (Big Five) model of personality. Smoking, alcohol use, body mass index (BMI), and self-rated health were assessed 40 years later in midlife. Childhood personality traits were significantly associated with all 4 outcomes, and the effects were consistently larger for women than men. For men and women, childhood Conscientiousness was associated with less adult smoking and better adult self-rated health and, for women only, with lower adult BMI. Mediation analyses suggested that the effects of Conscientiousness on self-rated health were partially mediated by smoking and BMI. These findings add to the growing evidence that childhood personality traits predict adult health outcomes and are discussed in terms of future testing of the life span health-behavior model.

Impact of environment on adolescent mental health and behavior: structural equation modeling

This study uses structural equation models to describe how objective neighborhood, perceived neighborhood, and environmental support predict mental health; 792 adolescents responded to highly structured interviews. The effect of objective environment on mental health was mediated through its influence on perceived neighborhood. Environmental support mitigated negative perceptions of environment and the effect of perceived environment on mental health, while exposure to violence augmented the negative effect of perceived environment.     

Perceived family criticism and primary care utilization: psychosocial and biomedical pathways

We explored the relationship of perceived family criticism to subsequent healthcare utilization in patients attending a family medicine center. We examined: a) the relationship of perceived criticism to subsequent utilization for biomedical and psychosocial/somatic problems; b) the mediating effects of self-rated mental health and physical function; and c) the mediating effects of social support. The analyses were adjusted for age, sex, race, education, health insurance, and martial status. Higher perceived criticism predicted more psychosocial/somatic and biomedical visits. The relationship of perceived criticism with psychosocial/somatic visits was entirely mediated through self-rated mental health. The relationship of perceived criticism with biomedical visits was partly mediated through self-rated physical function and, in part, independent. Social support played no role in explaining these relationships. Further research is needed to determine whether lowering perceived family criticism lowers primary care utilization.     

Three-year changes in cognitive performance as a function of apolipoprotein E genotype: Evidence from very old adults without dementia.

This study examined whether baseline cognitive performance and 3-year longitudinal changes were influenced by apolipoprotein E ε4 (APOE-ε4) allele. Participants consisted of 20 APOE-ε4 (2 ε2/ε4; 17 ε3/ε4; 1 ε4/ε4) and 54 non-ε4 (12 ε2/ε3; 42 ε3/ε3) very old adults without dementia (M?=?81.82?±?5.06 years) participating in a population-based longitudinal study. Cognitive performance was indexed by the Mini-Mental State Examination and multiple indexes of memory, visuospatial, and verbal performance. The results indicated no significant baseline differences between the 2 APOE groups in any cognitive performance measure. However, analyses revealed that the APOE-ε4 group experienced greater negative change in recognition memory for faces and words. Changes in tasks assessing other abilities did not vary as a function of APOE status. The authors concluded that APOE-ε4 status may not influence cognitive performance in adults without dementia and speculated that when such effects do occur (e.g., decline in recognition memory), these may be related to impending dementia, rather than to the influence of the specific genotype on cognition in normal aging.
