The uncharted waters of emotion: Ethnicity, trait emotion and emotion expression in older adults

Emotions are central to contemporary theories of health, and a growingbody of psychological research has shown emotion and emotion regulatorystyles to be predictive of health outcomes. Yet despite these clear links andthe fact that patterns of emotion and expression are partially a product ofculture, there is a meager literature on the emotional characteristics ofdifferent ethnic groups. Even where ethnicity has been investigated inemotions research, it has typically been operationalized in such a way thatwithin-group differences are obscured with most individuals assigned tobroad ethnic categories, such as non-Hispanic White, or Black. In thepresent study we draw on data from a multi-ethnic sample of 755community-dwelling older adults to parse a picture of the emotionalcharacteristics of three of the largest and most culturally distinct ethnicgroups in the Northeastern United States: African Americans, West Indians (Jamaicans), andEastern Slavs (Russians and Ukrainians) from the former Soviet Republic,as well as a comparison group of US-born European Americans. Aspredicted, there were striking differences in nine of 10 trait emotions aswell as in levels of emotion expressed during conflict. The findings arediscussed in terms of emotion socialization and implications for predictionand intervention in psychosocial models of emotions, emotion regulation,and health in older ethnic populations.     

The Older HIV-Positive Adult: A Critical Review of the Medical Literature

Older adults make up an ever-growing proportion of human immunodeficiency virus (HIV) cases in the United States, with approximately 25% of infections occurring in adults over the age of 50 years. Although there is a preliminary body of literature addressing the socioeconomic and prognostic issues of HIV infection in older adults, very little rigorous scientific research has looked at the significant clinical issues relevant to this growing population. Treatment of older adults is complicated by an increased prevalence of medical comorbidities, but little is known about the effects of complicated medication regimens in this group, as they are routinely excluded from clinical trials of newer HIV medications. The delay in diagnosis and treatment of HIV in older adults has led to poorer outcomes, including lower baseline CD4 counts, decreased time to acquired immune deficiency syndrome diagnosis, and increased mortality. Despite these facts, there is mounting evidence that timely diagnosis and treatment of HIV in older adults leads to improved outcomes, similar to younger patients. This review evaluates the literature focusing on HIV and older adults.     

The degree of kinship and its association with reciprocity and exchange in the relationships of visually impaired older adults

This study draws on an evolutionary model of exchange in relationships to examine the nature of perceived reciprocity in the context of kin and non-kin relationships among a sample of visually impaired older adults (age 63–99). Further, we examined the direct and moderating impact of functional impairment and adaptation to visual impairment on the nature of perceived reciprocity. Results showed that the greater the degree of genetic relatedness the more imbalanced the exchange. It was also found that degree of adaptation to visual impairment moderated the association between genetic relatedness and perceived exchange, such that the greater the degree of genetic relatedness the more people reported they gave rather than received except at very low levels of adaptation, when people received more than they gave the greater the degree of genetic relatedness. Thus, an evolutionary model was supported such that imbalanced exchange was found more with greater degrees of genetic relatedness, but the direction of exchange was different for high versus low levels of adaptation to vision impairment.     

Depression,anxiety and loss of resilience after multiple traumas: an illustration of a mediated moderation model of sensitization in a group of children who survived the Nazi Holocaust

Background

Depressive and anxiety disorders (DAD) have become a major public health problem. Multiple trauma is known to increase the risk of DAD through a sensitization mechanism. We investigate the hypothesis that resilience is a mediator of this mechanism.

Methods

Former Hidden Children (FHC), the Jewish youths who spent World War II in various hideaway shelters across Nazi-occupied Europe, were compared with a control group. In each group, we measured the presence of multiple traumas, the resilience with the Resilience Scale for Adults, which has a six factors solution, and the DAD with the Hopkins Symptoms Checklist. We test a mediated moderation model with childhood trauma as the predictor; Later trauma as the moderator; Resilience as the mediator; and DAD as the outcome variable.

Results

Results are consistent with a sensitization model of DAD mediated by resilience: confrontation with a primary trauma during childhood followed by secondary trauma(s) after childhood damages resilience, which, in turn, results in higher level of DAD.

Limitations

We are unable to differentiate if the sensitization process is a consequence of the nature of the trauma endured by FHC (long-standing exposure to extreme external events) or a consequence of the fact that this first trauma occurred during childhood.

Conclusions

Resilience construct is multi-factorial and a limited damaging of some of the factors is sufficient to lead to DAD even if other factors remain unaltered. Resilience can be altered by multiple traumas and, therefore, needs to be bolstered in therapy sessions.     

Prevalence and correlates of depression among HIV-infected and -affected older people in rural South Africa

Background

Little is known about depression in older people in sub-Saharan Africa, the associated impact of HIV, and the influence on health perceptions.

Objectives

Examine the prevalence and correlates of depression; explore the relationship between depression and health perceptions in HIV-infected and -affected older people.

Methods

In 2010, 422 HIV-infected and -affected participants aged 50+ were recruited into a cross-sectional study. Nurse professionals interviewed participants and a diagnosis of depressive episode was derived from the Composite International Diagnostic Interview (Depression module) using the International Classification of Diseases diagnostic criteria and categorised as major (MDE) or brief (BDE).

Results

Overall, 42.4% (n=179) had a depressive episode (MDE: 22.7%, n=96; BDE: 19.7%, n=83). Prevalence of MDE was significantly higher in HIV-affected (30.1%, 95% CI 24.0–36.2%) than HIV-infected (14.8%, 95% CI 9.9–19.7%) participants; BDE was higher in HIV-infected (24.6%, 95% CI 18.7–30.6%) than in HIV-affected (15.1%, 95% CI 10.3–19.8%) participants. Being female (aOR 3.04, 95% CI 1.73–5.36), receiving a government grant (aOR 0.34, 95% CI 0.15–0.75), urban residency (aOR 1.86, 95% CI 1.16–2.96) and adult care-giving (aOR 2.37, 95% CI 1.37–4.12) were significantly associated with any depressive episode. Participants with a depressive episode were 2–3 times more likely to report poor health perceptions.

Limitations

Study limitations include the cross-sectional design, limited sample size and possible selection biases.

Conclusions

Prevalence of depressive episodes was high. Major depressive episodes were higher in HIV-affected than HIV-infected participants. Psycho-social support similar to that of HIV treatment programmes around HIV-affected older people may be useful in reducing their vulnerability to depression.     

Health anxiety disorders in older adults: Conceptualizing complex conditions in late life

Health anxiety disorders (e.g., hypochondriasis) are prevalent but understudied in older adults. Existing research suggests that severe health anxiety has a late age of onset, perhaps because of comorbidity with physical health conditions that are more likely to occur with aging. Despite being under diagnosed in later life due to a lack of age-appropriate diagnostic criteria, significant positive associations with age suggest that health anxiety disorders are more prevalent in older than younger adults. Preliminary research also highlights the complexity of these disorders in older adults and the potential importance of medical morbidity as a risk factor. This review explores the complexities of health anxiety disorders in later life with a focus on understanding defining features, prevalence rates, correlates, assessment, diagnosis, and treatment. We offer a theoretical model of the development of severe health anxiety among older adults to encourage further research on this important and under-studied topic.     

Effects of initial foot position on postural responses to lateral standing surface perturbations in younger and older adults

BackgroundAn age-related decline in standing balance control in the medio-lateral direction is associated with increased risk of falls. A potential approach to improve postural stability is to change initial foot position (IFP).Research questionsIn response to a lateral surface perturbation, how are lower extremity muscle activation levels different and what are the effects of different IFPs on muscle activation patterns and postural stability in younger versus older adults?MethodsTen younger and ten older healthy adults participated in this study. Three IFPs were tested [Reference (REF): feet were placed parallel, shoulder-width apart; Toes-out with heels together (TOHT): heels together with toes pointing outward; Modified Semi-Tandem (M-ST): the heel of the anterior foot was placed by the big toe of the posterior foot]. Unexpected lateral translations of the standing surface were applied. Electromyographic (EMG) activity of the lower extremity muscles, standard deviation (SD) of the body’s CoM acceleration (SD of CoMAccel), and center of pressure (CoP) sway area were compared across IFPs and age.ResultsActivation levels of the muscles serving the ankle and gluteus medius were greater than for the knee joint muscles and gluteus maximus in the loaded leg across all IFPs in both groups. TOHT showed greater EMG peak amplitude of the soleus and fibularis longus compared to REF, and had smaller SD of CoMAccel and CoP sway area than M-ST. Compared to younger adults, older adults demonstrated lower EMG peak amplitude and delayed peak timing of the fibularis longus and greater SD of CoMAccel and CoP sway area in all IFPs during balance recovery.SignificanceDuring standing balance recovery, ankle muscles and gluteus medius are important active responders to unexpected lateral surface perturbations and a toes-out IFP could be a viable option to enhance ankle muscle activation that diminishes with age to improve postural stability.     

Has the prevalence of health care services use increased over the last decade (2001–2009) in elderly people? A Spanish population-based survey

Objectives

(1) To describe the prevalence of general practitioner visits and hospitalization according to sex and age groups; (2) to identify which factors are independently associated with a higher use of health care services among elderly Spanish; and (3) to study the time trends in the prevalence of use of health care services 2001–2009.

Study Design

Observational study. We analyzed data from the Spanish National Health Surveys conducted in 2001 (n = 21,058), 2003 (n = 21,650), 2006 (n = 29,478) and 2009 (n = 22,188). We included responses from adults aged 65 years and older.

Outcome measures

The main variables were the number of general practitioner visits in the last 4 weeks and hospitalization in the past year. We stratified the adjusted models by the main variables. We analyzed socio-demographic characteristics, health related variables, using multivariate logistic regression models.

Results

The total number of subjects was 24,349 (15,041 woman, 9309 men). Women were significantly older than men (P < 0.001). Women had higher prevalence of general practitioner visits than men in all surveys. Men had significantly higher prevalence of hospitalizations than women in the years 2001, 2006 and 2009. When we adjusted the hospitalization by possible confounders using logistic regressions, men had a higher probability of being hospitalized than women (OR 1.53, 1.39–1.69). The variables that were significantly associated with a higher use of health care services were lower educational level, worse self-rated health, chronic conditions, polypharmacy, and the level of disability. The number of general practitioner visits among women and men significantly increased from 2001 to 2009 (women: OR 1.43, 1.27–1.61; men: OR 1.71, 1.49–1.97).

Conclusions

The current study revealed an increase in health care services utilization from 2001 to 2009 in the older Spanish population.     

Stress hormones,sleep deprivation and cognition in older adults

Cognition can be deteriorated in older persons because of several potential mechanisms including the hormonal changes occurring with age. Stress events cause modification in hormonal balance with acute and chronic changes such as increase in cortisol and thyroid hormones, and simultaneous alterations in dehydroepiandrosterone sulphate, testosterone and insulin like growth factor-1 levels. The ability to cope with stress and regain previous healthy status, also called resiliency, is particularly impaired in older persons Thus, stressful conditions and hormonal dysregulation might concur to the onset of cognitive impairment in this population.     

The asthma knowledge and perceptions of older Australian adults: Implications for social marketing campaigns

Objective

The purpose of this research is to gain an understanding of the asthma perceptions of older adults and identify gaps in their asthma knowledge.

Methods

In regional New South Wales, Australia, a stratified, random sample of 4066 adults, aged 55 years and over, both with and without an asthma diagnosis, completed a survey based on the Health Belief Model about asthma knowledge and perceptions.

Results

Almost half of the sample had experienced symptoms of breathlessness in the past four weeks. Breathlessness was a predictor of lower health ratings and poorer mood. Older adults reported low susceptibility to developing asthma. The sample demonstrated poor knowledge of key asthma symptoms including shortness of breath, tightness in the chest and a cough at night.

Conclusion

There is a general lack of asthma awareness in this age group. This could result in not seeking medical help, and thus a reduced quality of life.

Practical Implications

Older adults should be made aware of key symptoms and the prevalence of asthma in the older adult population, and be empowered to take control of their respiratory health. Audience segmentation for an intervention should be based on recent experience of breathlessness and asthma diagnosis.
