Anxiety, depression, psychotropic drug use and cognitive impairment

BACKGROUND: Numerous studies have shown that anxiety and depression are related to cognitive impairment, but the concomitant association between anxious symptoms, depressive symptoms and cognitive function has not been investigated, and, most studies have not considered psychotropic drug use as a possible confounding factor. METHODS: We assessed the independent association between depression, anxiety, psychotropic drug use and cognitive performance in 457 men and 659 women, aged 59-71 years living in the community. Data on demographic background, occupation, medical history, drug use and personal habits were obtained using a standardized questionnaire. The Spielberger Inventory Trait and the Center for Epidemiologic Study-Depression (CES-D) scales were used to evaluate anxious and depressive symptomatology respectively. Cognitive assessment included six traditional tests covering the main areas of cognitive functioning. RESULTS: In men, anxious and depressive symptomatologies had independent significant associations with most cognitive abilities, independent of psychotropic drug use. In women, the association between anxiety or depression and cognitive functioning was less strong and disappeared after adjustment for psychotropic drug use. Psychotropic drug use was associated with lower cognitive scores in both sexes. In men with high CES-D scores, we found positive correlations between anxiety level and cognitive scores. CONCLUSIONS: The study showed that anxiety, depression and psychotropic drug use were significantly and independently associated with cognitive functioning in elderly men. The high prevalence of psychotropic drug use in women with or without psychological disorders may explain its major effect in women. Results suggested that anxiety may partly compensate for some negative effects of depression on cognitive functioning.     

Psychological symptoms and blood pressure among rural-dwellers

Rural-dwelling adults face different health concerns and risks than do adults living in urban areas, with reduced assess to care. Studies examining the associations between anxiety and/or depression and blood pressure have yielded mixed results. This study addressed this by examining the association of these symptoms to blood pressure in men compared to women, and for differing racial groups in a rural population in the western United States. Analyses indicate the association between depression and blood pressure differs by race. Further, depressive symptoms were associated with higher diastolic blood pressure for participants at or above the mean of anxiety.     

Does less autonomy erode women's health? Yes. No. Maybe

Understanding the determinants of health is a central objective of human biology and related fields. Female autonomy is hypothesized to be an important determinant of women's health as well as demographic outcomes. The literature relating women's health to their everyday autonomy has produced conflicting results, and this may be due in part to the application of different measures of autonomy and different measures of health. Using secondary data from a large nationally representative study, this study examines the relationship between multiple measures of female autonomy and three measures of wellbeing among women living in Uzbekistan (n = 5,396). The multivariate results show that women's autonomy related to freedom of movement is associated with lower levels of depression symptomatology and lower systolic blood pressure. Respondents who assert that women should have control over their bodies also had lower odds of high depression symptoms and lower diastolic blood pressure. In contrast, women with greater decision‐making autonomy were more likely to be classified as having high depressive symptomatology and higher diastolic blood pressure. Building on recent work, we suggest that these associations might reflect varying levels of agreement between men and women, and we provide some limited evidence to support this. This study stands as a theoretical and methodological cautionary note by suggesting that the relationship between autonomy and health is complex. Further, if differences in gender agreement underlie differences in the predictive accuracy of autonomy scales, then human biology researchers will need to begin collecting identical data from men and women.

The state-trait anxiety inventory and sex

This study sought to investigate the response pattern of male and female subjects to the state-trait anxiety inventory (STAI) under anxiety-provoking and normal conditions. The relationship between the STAI and systolic and diastolic blood pressures for both men and women under the above-mentioned conditions was also examined. We found that the STAI X-2 and the systolic blood pressure discriminated between the sexes and the treatment conditions. On the average, both men and women scored significantly higher during the anxiety-provoking stimulus situation than during the normal condition on systolic and diastolic blood pressures. The men seemed to be more prone to anxiety than the women. We also found that, STAI X-1 related negatively to both the systolic and diastolic blood pressures in the anxious condition among men, while it related positively to the systolic and diastolic blood pressure among women. During the “calm” period, while STAI X-1 and X-2 were unrelated to systolic and diastolic blood pressure among men, the STAI X-2 correlated positively with systolic and diastolic blood pressures among women.

Emotional responsivity during daily life: relationship to psychosocial functioning and ambulatory blood pressure.

Emotional responsivity refers to acute changes in affective states. This study examined the relationship of emotional responsivity during daily life with ambulatory blood pressure (ABP) and psychosocial functioning. Subjects were 162 employed men and women, aged 25-45 years. Subjects underwent 24-h ABP monitoring in which they completed a behavioral diary with each cuff inflation. On a separate day, subjects completed a psychometric test battery including measures of depression, trait anxiety, and social support. Emotional Responsivity, an index of negative emotional variability during waking hours, was operationalized as the standard deviation of each individual's negative emotions scores throughout the day. Individuals with high levels of emotional responsivity showed greater increases in ABP and heart rate (HR) associated with negative emotions. Emotionally responsive individuals also reported less satisfaction with social support and higher levels of perceived daily stress, trait anxiety, and depressive symptoms. These findings suggest that psychosocial traits that have been linked to cardiovascular disease may be associated with more marked cardiovascular activation occurring in response to negative emotions experienced throughout the day.     

Relation of high cytomegalovirus antibody titres to blood pressure and brachial artery flow-mediated dilation in young men: the Cardiovascular Risk in Young Finns Study

Human cytomegalovirus (CMV) infection is associated with a higher risk of cardiovascular disease in immunocompromised organ transplant patients. It has been linked with the pathogenesis of elevated arterial blood pressure. However, controversy exists as to whether CMV infection is associated with endothelial function, and little is known about its role as a potential risk factor for early atherosclerosis development at a young age. We aimed to discover if CMV antibody titres are associated with early vascular changes (carotid intima-media thickness, carotid artery distensibility and brachial artery flow-mediated dilation), blood pressure elevation or other traditional cardiovascular risk factors. CMV antibody titres were measured in 1074 women and 857 men (aged 24-39 years) taking part in the Cardiovascular Risk in Young Finns study. CMV antibody titres were significantly higher in women compared to men. In men, high CMV antibody titres were associated directly with age (P < 0·001) and systolic (P = 0·053) and diastolic (P = 0·002) blood pressure elevation, and associated inversely with flow-mediated dilation (P = 0·014). In women, CMV antibody titres did not associate with any of the analysed parameters. In a multivariate regression model, which included traditional atherosclerotic risk factors, CMV antibody titres were independent determinants for systolic (P = 0·029) and diastolic (P = 0·004) blood pressure elevation and flow-mediated dilation (P = 0·014) in men. High CMV antibody titres are associated independently with blood pressure and brachial artery flow-mediated dilation in young men. This association supports the hypothesis that common CMV infection and/or an immune response to CMV may lead to impaired vascular function at a young age.     

Indoleamine 2,3-dioxygenase activation and depressive symptoms: results from the young Finns study

Objective To examine whether the activation of indoleamine 2,3-dioxygenase (IDO), an enzyme involved in serotonin production, is associated with depressive symptoms. Methods The participants were 544 women and 442 men (aged 24-39 years) from the population-based Young Finns Study who participated in a medical examination in 2001 (including IDO and depression) and 2007 (follow-up assessment for depression). Results At baseline, IDO was associated with depressive symptoms (in the total cohort: B = 0.23, p < .001; women: B = 0.20, p = .007; men: B = 0.29, p = .002; p for interaction = .19). IDO at baseline was also associated with depressive symptoms at follow-up in women (B = 0.17, p = .03), which remained significant when adjusting for any of the biologic and behavioral risk factors. Adjusting for body mass index attenuated the association by 6%. In the final model including all baseline variables, none of the risk factors (except for baseline depressive symptoms) were associated with depressive symptoms at follow-up. Conclusions These data suggest that IDO activity may be a risk factor for future depression especially in women. IDO-induced alterations in serotonergic function may offer one biologic explanation to the well-established associations between inflammation and depression.     

围产期女性不同时点抑郁症状检出率及影响因素

目的:了解妇女在围产期不同时点的抑郁症状检出率及其影响因素。方法:2016年9月到2017年2月,在两家妇幼保健院进行产检的508名妇女中完成了全部时点的随访(从孕早期至产后6周,随访7次),使用爱丁堡产后抑郁量表(EPDS)进行抑郁筛查,计算所有时点的抑郁症状检出率,同时在各个时点测量抑郁影响因素。结果:7次随访的抑郁症状检出率为24.8%~37.6%;产后两个时点的中重度抑郁症状检出率均高于轻度抑郁症状(13.0%~14.3%vs.11.8%~13.0%,均P<0.05)。孕早期抑郁症状(OR=2.54、2.05)和产后焦虑(OR=1.43、1.13)与产后1周及产后6周的抑郁症状均正向关联;孕早期焦虑与孕12周至40周共5个时点的抑郁症状正向关联(OR=7.27、1.28、1.18、1.18、1.18)。结论:围产期不同时点的抑郁症状检出率不同,焦虑在整个围产期都与抑郁持续相关。     

Estrogen replacement therapy, subsyndromal depression, and orthostatic blood pressure regulation

Although estrogen replacement therapy (ERT) alleviates depressed moods in postmenopausal women, it is not known whether ERT is equally effective in reducing affective and somatic depressive complaints. One of the authors' goals in this study was to examine possible differences between women receiving and not receiving ERT. The authors studied a group of postmenopausal women. Somatic symptoms in the ERT group were significantly lower than in the Non-ERT group. Affective scores were only marginally lower in the ERT group (p = .06). After controlling for affective depression, the advantage of ERT remained significant with respect to somatic levels, but control for somatic levels essentially eliminated the effects of ERT on affective depression values. Second, in response to orthostatic challenge, the change in systolic blood pressure was significantly smaller in the ERT group. Apparently ERT is associated with more effective blood pressure regulation. Thus there are several potential benefits of ERT, despite recent evidence finding several untoward effects of long-term treatment.     

Race and sex differences in cutaneous pain perception

OBJECTIVE: The purpose of this study was to determine race and sex differences in cutaneous pain perception. METHODS: Pain perception was measured using a suprathreshold evaluation of pain intensity and pain unpleasantness to a series of thermal stimuli in 27 whites (14 men and 13 women) and 24 African Americans (12 men and 12 women). Blood pressure, depressive symptoms, anxiety state levels, and negative mood were assessed before pain testing to examine whether they might account for any sex or race differences in pain perception that emerged. RESULTS: African Americans rated the stimuli as more unpleasant and showed a tendency to rate it as more intense than whites. Women showed a tendency to rate the stimuli as more unpleasant and more intense than men. In addition, systolic blood pressure was inversely related to pain intensity. After statistically adjusting for systolic blood pressure, sex differences in pain unpleasantness were reduced and sex differences in pain intensity were abolished; race differences were unaltered. CONCLUSIONS: These differences in pain perception may be associated with different pain mechanisms: in the ease of sex, differences in opioid activity and baroreceptor-regulated pain systems; in the case of race, unmeasured psychological characteristics are suggested by the larger differences in ratings of pain unpleasantness than pain intensity.     

Anxiety reduces baroreflex cardiac control in older adults with major depression.

OBJECTIVE: Although depression and anxiety predict risk of cardiac mortality, the contributions of depression and anxiety to vagal cardiac control have not been systematically evaluated. The goal of this study was to examine the relationship between state anxiety and vagal control of heart rate in older adults with major depressive disorder (MDD). Older adults (50-70 years old) were selected for this study because of the greater cardiac risk associated with low vagal cardiac control across this age range. METHODS: Fifty-six men and women with MDD were evaluated. MDD was diagnosed using the Diagnostic Interview Schedule, and severity of depression was measured using the Beck Depression Inventory and the Hamilton Rating Scale for depression. State anxiety was measured using the Spielberger State Anxiety Inventory. Power spectral analysis was used to measure two indices of vagal control: baroreflex control of heart rate (BRC(SPEC)) and respiratory sinus arrhythmia (RSA). RESULTS: State anxiety was negatively correlated with levels of BRC(SPEC) (r = -0.32, p < .05), whereas depression severity was not related to either RSA or BRC(SPEC). Furthermore, BRC(SPEC) was reduced by approximately 33% in MDD patients with state anxiety scores (ST-ANX) in the highest quartile (ST-ANX > 41, N = 13), compared with patients with ST-ANX scores in the lowest quartile (ST-ANX < 25, N = 14; p < .05). CONCLUSIONS: Anxiety, but not depression severity, is associated with reduced BRC(SPEC) in older men and women. Future studies are needed to determine whether comorbid anxiety contributes to the increased cardiovascular risk associated with MDD.     

Influence of cholesterol and fasting insulin levels on blood pressure reactivity

OBJECTIVE: This study examined how cholesterol and fasting insulin levels are related to blood pressure reactivity to behavioral stressors. METHODS: Subjects (N = 116) were 20 to 52 years old, at 80% to 150% of ideal weight, and had an average fasting cholesterol level of 183 mg/dl. Stressor tasks included mirror star tracing and a videotaped speech task. Changes from baseline were calculated for systolic and diastolic blood pressure. RESULTS: Neither cholesterol nor insulin was independently related to blood pressure change scores. However, after controlling for body mass, a two-way analysis of variance revealed a significant cholesterol-by-insulin interaction for change in diastolic blood pressure (p = .022). Subjects in the high-cholesterol/high-insulin group showed the greatest increase in diastolic blood pressure reactivity. CONCLUSIONS: In a general population, people with a below-average cholesterol level experience only moderate cardiovascular reactivity to mental stressors regardless of their fasting insulin level. However, for people with an above-average cholesterol level, fasting insulin level is an important factor in determining potential reactivity to mental stressors. These findings highlight the importance of adequate sample size to allow for the analysis of such interactions in future studies of cholesterol, insulin, and blood pressure reactivity.     

Seasonality is associated with anxiety and depression: the Hordaland health study

BACKGROUND: The purpose of this study was to assess how seasonal changes in mood and behaviour were associated with depression and anxiety symptoms in a sample from a general population, and to investigate how prevalence figures were affected by month of questionnaire completion. METHODS: The target population included all individuals in the Hordaland county (Norway) born 1953-57 (N=29,400). In total, 8598 men (57% response rate) and 9983 women (70% response rate) attended the screening station. Half of the men (randomly chosen) and all of the women were offered a questionnaire to fill in with items on seasonality. This was measured using the Global Seasonality Score (GSS), a central component of the Seasonal Pattern Assessment Questionnaire (SPAQ). The Hospital Anxiety and Depression Scale (HADS) was used to measure anxiety and depression. Both questionnaires were completed by 2980 men (68.9%) and 8074 women (80.9%). RESULTS: Seasonality was positively associated with levels of both anxiety and depression regardless of the season the interview took place. In subjects with a low/moderate degree of seasonality there were modestly higher levels of depressive symptoms during November through March than the other months. LIMITATIONS: We had a substantial number of non-responders. CONCLUSIONS: Our results raise the possibility of seasonality being a separate dimensional trait associated with both anxiety and depression.     

John Henry Active Coping, education, and blood pressure among urban blacks

The John Henryism hypothesis posits that individuals who actively cope with psychosocial stressors in the face of low socioeconomic resources are more likely to exhibit higher blood pressure levels than those with greater socioeconomic resources. It has been proposed that John Henryism may contribute to the disproportionately high rates of hypertension among blacks. Previous studies which support the John Henryism hypothesis have been conducted among blacks who reside in primarily southern rural settings. However, more recent studies conducted among urban blacks, have yielded contrasting results. This study examined the John Henryism hypothesis in a middle-aged urban sample of blacks in south Florida. The results of the study confirmed that there is indeed a relationship among John Henry Active Coping, years of education, and blood pressure among urban blacks in south Florida. Upon closer examination, higher John Henry Active Coping scores were associated with higher systolic and diastolic blood pressure among higher educated men, and John Henry Active Coping scores were associated with higher systolic and diastolic blood pressure among women with lower levels of education. The findings are discussed in terms of sociocultural factors that may influence the coping styles of black men and women in different communities and environments.     

Dominance, gender, and cardiovascular reactivity during social interaction

Associations between trait dominance and cardiovascular reactivity were examined in previously unacquainted healthy men and women. Subjects participated in three mixed-gender dyadic interactions with the same partner while their cardiovascular responses were assessed. Among men, but not women, trait dominance was positively and significantly associated with systolic blood pressure reactivity. For men and women, diastolic blood pressure reactivity was positively and significantly associated with trait dominance while participants prepared to interact and with partner's trait dominance while they interacted. All effects held after controlling for trait hostility. Dominance merits attention as a correlate of cardiovascular reactivity, a finding that parallels emerging patterns in the cardiovascular disease literature. Gender and gender-related social factors as potential moderators of this relationship are discussed.     

Reduced frontal perfusion in depressed postmenopausal women: a SPECT study with WCST

OBJECTIVES: To investigate frontal cerebral blood flow (CBF) in depressed postmenopausal women and its relation to cognitive function and the severity of depressive symptoms. METHODS: Regional CBF of 20 unmedicated depressed postmenopausal women was measured using Tc-99m HMPAO SPECT, both at rest and during frontal activation using the Wisconsin card sorting test (WCST). Frontal CBF was semi-quantified by comparing the radioactivity in the prefrontal region to the cerebellum (F/C ratio). We measured the severity of the symptoms of depression using the hospital anxiety and depression scale (HADS) and cognitive function using the mini-mental status examination (MMSE). RESULTS: At rest, there was no difference in frontal CBF between patients with moderate or severe (HADS> or =11) and patients with mild depressive symptoms (HADS<11). During the WCST, however, the HADS> or =11 group did not score as well as the HADS<11 group (P=0.03). The changes in F/C ratios were inversely correlated with HADS scores (r=-0.43, P=0.05) and positively correlated with MMSE scores (r=0.58, P=0.004). After adjusting for age, F/C ratios were significantly correlated with MMSE (P=0.002), but not with HADS scores. CONCLUSIONS: Frontal CBF did not increase in postmenopausal women with moderate/severe symptoms of depression during the WCST activation task, and reduced frontal CBF was related to the impairment of cognitive function. The combination of the functional activation test and SPECT imaging powerfully revealed this functional disease, which remains undetectable using more common baseline measurements.     

The influence of happiness, anger, and anxiety on the blood pressure of borderline hypertensives

Differences in blood pressure associated with reported happiness, anger, and anxiety are examined among 90 borderline hypertensives during 24-hr blood pressure monitoring. There were 1152 individual ambulatory blood pressure readings for which subjects classified their emotional state as happy (n = 628), angry (n = 67), or anxious (n = 457) on scales from one (low) to ten (high). Pressures were transformed to z-scores using the subject's 24-hr mean and standard deviation to assess relative elevation during reported emotional arousal. The results show that emotional arousal significantly increases systolic and diastolic pressure (p less than 0.00001), an effect independent of posture and location of subject during measurement (at work, home, or elsewhere). On average, pressures during reported angry or anxious states were higher than those during a happy state (p less than 0.01). Examination of arousal intensity showed that scores on the happiness scale were inversely related to systolic pressure (p less than 0.01) whereas the degree of anxiety was positively associated with diastolic pressure (p less than 0.02). Emotional effects were also related to the degree of individual daily pressure variation such that the greater the variability, the larger the blood pressure change associated with the emotions. The results suggest that happiness, anger, and anxiety increase blood pressure to differing degrees and that emotional effects may be greater in individuals with more labile blood pressure.     

Understanding the link between anxiety symptoms and suicidal ideation and behaviors in outpatients with bipolar disorder

BACKGROUND: Prior studies suggest an association between anxiety comorbidity and suicidal ideation and behaviors in bipolar disorder. However, the nature of this association remains unclear. METHODS: We examined a range of anxiety symptoms, including panic, phobic avoidance, anxiety sensitivity, worry and fear of negative evaluation, in 98 patients with bipolar disorder. We predicted that each anxiety dimension would be linked to greater suicidal ideation and behavior as measured by Linehan's Suicide Behaviors Questionnaire (SBQ), greater depressive rumination, and poorer emotional processing and expression. RESULTS: Each anxiety dimension except fear of negative evaluation was associated with greater SBQ score, greater rumination, and lower levels of emotional processing in univariate analyses. Depressive rumination was a significant predictor of higher SBQ scores in a stepwise multivariate model controlling for age, gender, bipolar subtype, and bipolar recovery status; the association between the anxiety symptom dimensions and SBQ score was found to be redundant with depressive rumination. Emotional processing emerged as protective against suicidal ideation and behaviors in men only, while emotional expression was a significant predictor of lower SBQ scores for women and for the full sample; however, emotional expression was not significantly correlated with anxiety symptoms. Confirmatory analyses examining only those in recovery or recovered (n=68) indicated that the link between rumination and suicidality was not explained by depression. LIMITATIONS: Interpretation is limited by the cross-sectional study design. CONCLUSIONS: These findings indicate that increased ruminations may mediate the association between anxiety and suicidal ideation/behavior. In men, lower emotional processing may also play a role in this relationship.
