Winning Big But Feeling No Better? The Effect of Lottery Prizes on Physical and Mental Health

Benedicte Apouey & Andrew Clark
Health Economics, forthcoming

Abstract:
We use British panel data to determine the exogenous impact of income on a number of individual health outcomes: general health status, mental health, physical health problems, and health behaviours (drinking and smoking). Lottery winnings allow us to make causal statements regarding the effect of income on health, as the amount won by winners is largely exogenous. Positive income shocks have no significant effect on self-assessed overall health, but a significant positive effect on mental health. This result seems paradoxical on two levels. First, there is a well-known gradient in health status in cross-sectional data, and second, general health should partly reflect mental health, so that we may expect both variables to move in the same direction. We propose a solution to the first apparent paradox by underlining the endogeneity of income. For the second, we show that lottery winnings are also associated with more smoking and social drinking. General health will reflect both mental health and the effect of these behaviours and so may not improve following a positive income shock.

School Mobility and Prospective Pathways to Psychotic-Like Symptoms in Early Adolescence: A Prospective Birth Cohort Study

Swaran Singh et al.
Journal of the American Academy of Child & Adolescent Psychiatry, forthcoming

Objective: Social adversity and urban upbringing increase the risk of psychosis. We tested the hypothesis that these risks may be partly attributable to school mobility and examined the potential pathways linking school mobility to psychotic-like symptoms.

Method: A community sample of 6,448 mothers and their children born between 1991 and 1992 were assessed for psychosocial adversities (i.e., ethnicity, urbanicity, family adversity) from birth to 2 years, school and residential mobility up to 9 years, and peer difficulties (i.e., bullying involvement and friendship difficulties) at 10 years. Psychotic-like symptoms were assessed at age 12 using the Psychosis-like Symptoms Interview (PLIKSi).

Results: In regression analyses, school mobility was significantly associated with definite psychotic-like symptoms (Odds Ratio [OR] =1.60; 95% Confidence Interval [C.I] =1.07 to 2.38) after controlling for all confounders. Within path analyses, school mobility (Probit co-efficient [β] = 0.108; p = 0.039), involvement in bullying (β = 0.241; p < 0.001), urbanicity (β = 0.342; p = 0.016) and family adversity (β = 0.034; p < 0.001) were all independently associated with definite psychotic-like symptoms. School mobility was indirectly associated with definite psychotic-like symptoms via involvement in bullying (β = 0.018; p = 0.034).

Conclusions: School mobility is associated with increased risk of psychotic-like symptoms both directly and indirectly. The findings highlight the potential benefit of strategies to help mobile students establish themselves within new school environments in order to reduce peer difficulties, and diminish the risk of psychotic-like symptoms. Awareness of mobile students as a possible high-risk population and routine inquiry regarding school changes and bullying experiences may be advisable in mental health care settings.

Paternal Age at Childbearing and Offspring Psychiatric and Academic Morbidity

Brian D’Onofrio et al.
JAMA Psychiatry, forthcoming

Objective: To examine the associations between advancing paternal age at childbearing and numerous indexes of offspring morbidity.

Design, Setting, and Participants: We performed a population-based cohort study of all individuals born in Sweden in 1973-2001 (N = 2 615 081), with subsets of the data used to predict childhood or adolescent morbidity. We estimated the risk of psychiatric and academic morbidity associated with advancing paternal age using several quasi-experimental designs, including the comparison of differentially exposed siblings, cousins, and first-born cousins.

Results: In the study population, advancing paternal age was associated with increased risk of some psychiatric disorders (eg, autism, psychosis, and bipolar disorders) but decreased risk of the other indexes of morbidity. In contrast, the sibling-comparison analyses indicated that advancing paternal age had a dose-response relationship with every index of morbidity, with the magnitude of the associations being as large or larger than the estimates in the entire population. Compared with offspring born to fathers 20 to 24 years old, offspring of fathers 45 years and older were at heightened risk of autism (hazard ratio [HR] = 3.45; 95% CI, 1.62-7.33), attention-deficit/hyperactivity disorder (HR = 13.13; 95% CI, 6.85-25.16), psychosis (HR = 2.07; 95% CI, 1.35-3.20), bipolar disorder (HR = 24.70; 95% CI, 12.12-50.31), suicide attempts (HR = 2.72; 95% CI, 2.08-3.56), substance use problems (HR = 2.44; 95% CI, 1.98-2.99), failing a grade (odds ratio [OR] = 1.59; 95% CI, 1.37-1.85), and low educational attainment (OR = 1.70; 95% CI, 1.50-1.93) in within-sibling comparisons. Additional analyses using several quasi-experimental designs obtained commensurate results, further strengthening the internal and external validity of the findings.

Conclusions and Relevance: Advancing paternal age is associated with increased risk of psychiatric and academic morbidity, with the magnitude of the risks being as large or larger than previous estimates. These findings are consistent with the hypothesis that new genetic mutations that occur during spermatogenesis are causally related to offspring morbidity.

Ripple Effects of Developmental Disabilities and Mental Illness on Nondisabled Adult Siblings

Barbara Wolfe et al.
Social Science & Medicine, May 2014, Pages 1–9

Abstract:
Developmental disabilities and severe mental illness are costly to the affected individual and frequently to their family as well. Little studied are their nondisabled siblings. Here we examine major life course outcomes (education, employment, and marriage) of these siblings in adulthood using data from the Wisconsin Longitudinal Study. Our sample comprises 113 individuals with developmental disabilities and 337 of their nondisabled siblings; 97 individuals with mental illness and 235 of their nondisabled siblings; and 17,126 unaffected comparison group members. We find that siblings of individuals with mental illness have less education and less employment than the unaffected comparison group, whereas those who have a sibling with developmental disabilities had normative patterns of education and employment, but less marriage and more divorce. Robustness tests incorporating genetic data do not change the conclusions based on the nongenetic analyses.

Worrying about the Stock Market: Evidence from Hospital Admissions

Joseph Engelberg & Christopher Parsons
University of California Working Paper, March 2013

Abstract:
Using individual patient records for every hospital in California from 1983-2011, we find a strong inverse link between daily stock returns and hospital admissions, particularly for psychological conditions such as anxiety, panic disorder, or major depression. The effect is nearly instantaneous (within the same day), suggesting that anticipation over future consumption directly influences instantaneous utility, e.g., Caplin and Leahy (2001). Moreover, the effect of such anticipation is path dependent, being strongest during low volatility regimes, and immediately following low returns.

Long-Term Effects of Conflict-Related Sexual Violence Compared with Non-Sexual War Trauma in Female World War II Survivors: A Matched Pairs Study

Philipp Kuwert et al.
Archives of Sexual Behavior, forthcoming

Abstract:
The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

Childhood maltreatment and personality disorders in the USA: Specificity of effects and the impact of gender

Rachel Waxman et al.
Personality and Mental Health, February 2014, Pages 30–41

Abstract:
Childhood maltreatment increases the risk for adult personality disorders (PDs), but several PDs or maltreatment types co-occur. Specificity of maltreatment–personality associations is poorly understood. Using a representative US population sample, we identified specific associations between maltreatment types (sexual, physical and emotional abuse and physical and emotional neglect) and PDs after controlling for basic demographics, parental psychopathology, co-occurring maltreatment types and comorbid PD. We then examined interactions of gender and maltreatment in predicting PDs. Each maltreatment type significantly predicted three–four PDs. Borderline and schizotypal PDs were most strongly predicted by sexual abuse, antisocial by physical abuse and avoidant and schizoid by emotional neglect. Specific vulnerabilities differ by gender; maltreated boys may respond with attention seeking and girls with social withdrawal. Findings highlight the importance of evaluating all forms of maltreatment even when they co-occur and can inform development of interventions to prevent personality pathology in at-risk children.

Suicide assisted by right-to-die associations: A population based cohort study

Nicole Steck et al.
International Journal of Epidemiology, forthcoming

Background: In Switzerland, assisted suicide is legal but there is concern that vulnerable or disadvantaged groups are more likely to die in this way than other people. We examined socio-economic factors associated with assisted suicide.

Methods: We linked the suicides assisted by right-to-die associations during 2003–08 to a census-based longitudinal study of the Swiss population. We used Cox and logistic regression models to examine associations with gender, age, marital status, education, religion, type of household, urbanization, neighbourhood socio-economic position and other variables. Separate analyses were done for younger (25 to 64 years) and older (65 to 94 years) people.

Results: Analyses were based on 5 004 403 Swiss residents and 1301 assisted suicides (439 in the younger and 862 in the older group). In 1093 (84.0%) assisted suicides, an underlying cause was recorded; cancer was the most common cause (508, 46.5%). In both age groups, assisted suicide was more likely in women than in men, those living alone compared with those living with others and in those with no religious affiliation compared with Protestants or Catholics. The rate was also higher in more educated people, in urban compared with rural areas and in neighbourhoods of higher socio-economic position. In older people, assisted suicide was more likely in the divorced compared with the married; in younger people, having children was associated with a lower rate.

Conclusions: Assisted suicide in Switzerland was associated with female gender and situations that may indicate greater vulnerability such as living alone or being divorced, but also with higher education and higher socio-economic position.

Regular Aerobic Exercise Increases Dispositional Mindfulness in Men: A Randomized Controlled Trial

Hendrik Mothes et al.
Mental Health and Physical Activity, forthcoming

Abstract:
Dispositional mindfulness is a construct described as the propensity to be aware of one’s actions in everyday life. Although high dispositional mindfulness has been demonstrated to be beneficial for improved mental and physical health, little is known about ways to improve dispositional mindfulness for individuals not practicing meditation or mindful exercises. The study aimed at investigating (1) whether dispositional mindfulness can also be trained by regular aerobic exercise and (2) whether changes in dispositional mindfulness are associated with changes in mental and physical health. 149 healthy men were randomly allocated to one of two 12-week interventions (aerobic exercise or relaxation training) or a waitlist control condition. Dispositional mindfulness and mental and physical health were assessed before and after the intervention by self-report questionnaires. Over the course of the intervention, increases in dispositional mindfulness occurred in the aerobic exercise group but not in the relaxation or waitlist control conditions (p = .018). Increases in dispositional mindfulness were moderately correlated with improvements in mental health. For the first time, this study shows that dispositional mindfulness can be increased through regular aerobic exercise. Future research is needed to identify how the mindfulness-enhancing potential of aerobic exercise can be used most effectively.

Shorter telomeres with high telomerase activity are associated with raised allostatic load and impoverished psychosocial resources

Argita Zalli et al.
Proceedings of the National Academy of Sciences, forthcoming

Abstract:
Recent work has linked psychological stress with premature cellular aging as indexed by reduced leukocyte telomere length. The combination of shorter telomeres with high telomerase activity (TA) may be indicative of active cell stress. We hypothesized that older individuals characterized by shorter telomeres with high TA in unstimulated leukocytes would show signs of high allostatic load and low levels of protective psychosocial resources. We studied 333 healthy men and women aged 54–76 y who underwent laboratory testing in which we measured cardiovascular, neuroendocrine, and inflammatory responses to standardized mental stress tasks. The tasks elicited prompt increases in blood pressure (BP), heart rate, cortisol, and mediators of inflammation and reductions in heart rate variability, returning toward baseline levels following stress. However, men having shorter telomeres with high TA showed blunted poststress recovery in systolic BP, heart rate variability, and monocyte chemoattractant protein-1, together with reduced responsivity in diastolic BP, heart rate, and cortisol, in comparison to men with longer telomeres or men with shorter telomeres and low TA. Shorter telomeres with high TA were also associated with reduced social support, lower optimism, higher hostility, and greater early life adversity. These effects were independent of age, socioeconomic status, and body mass index. We did not observe differences among older women. Our findings suggest that active cell stress is associated with impaired physiological stress responses and impoverished psychosocial resources, reflecting an integration of cellular, systemic, and psychological stress processes potentially relevant to health in older men.

The effect of the physical environment and levels of activity on affective states

Florence-Emilie Kinnafick & Cecilie Thøgersen-Ntoumani
Journal of Environmental Psychology, forthcoming

Abstract:
The physical environment and physical activity can independently improve positive affect. The current studies investigated the effects of two opposing environments (urban versus natural) and levels of activity (walking and sitting) on affective states in either a laboratory (study 1) or an outdoor setting (study 2). While doing each activity (walking and sitting in each environment), participants watched film clips of urban or natural outdoor settings (study 1), or were naturally immersed in an urban or a natural environment (study 2). Measures of affect were administered pre, mid and post each condition. Findings highlighted the benefits of being immersed in a natural outdoor environment with physical activity being key for positive effects on energy. Short bouts of sedentary behaviour increased state negative affect, tiredness, and decreased energy levels. Attempts by policy-makers, urban planners and public health promoters should encourage greater use of natural open space to promote acute psychological well-being.

Overt head movements moderate the effect of depressive symptoms on mood regulation

Juan Rahona et al.
Cognition & Emotion, forthcoming

Abstract:
A dysfunction in the regulation of negative mood states is one of the core symptoms of depression. Research has found that levels of depression are associated with the intensity of the mood-regulation deficit. The present study aimed to explore the role the body plays in mood-regulation processes. More specifically, we studied whether head movements can influence mood persistence in dysphoric states. Subsequent to a sad-mood induction, participants were presented with a set of positive pictures immediately after performing either vertical (i.e., nodding) or lateral (i.e., shaking) head movements. We considered changes in mood from before to after the experimental task as an index of the effectiveness of mood regulation. As expected, the results showed that higher initial levels of depressive symptoms were associated with greater persistence of sad mood. More importantly, this association was present in participants who shook their heads, but not in those who nodded. These results show that body movements can contribute to mood-regulation processes, thus expanding our knowledge of the psychopathology of mood disorders.
