Life events, social support and depression in childbirth: perspectives from a rural community in the developing world

BACKGROUND: High rates of depression associated with childbirth have been reported in many parts of the developing world. However, the prevalence and associations of antenatal and post-natal depression in the rural population remain unknown. Disability associated with depression and its impact on infant health and development could have important public health implications for many developing countries where large proportions of the population are rural. METHOD: All women living in southern Kahuta, Pakistan, in their third trimester of pregnancy were interviewed at 6 weeks before delivery (N = 632) and again at 10-12 weeks after delivery (N = 541), using WHO Schedule for Clinical Assessment in Neuropsychiatry (SCAN), Personal Information Questionnaire (PIQ) and Brief Disability Questionnaire (BDQ). RESULTS: The point prevalence of ICD-10 depressive disorder was 25% in the antenatal period and 28 % in the post-natal period. Depressed mothers were significantly more disabled, had more threatening life events, and poorer social and family support than non-depressed mothers. Vulnerable mothers were more likely to be depressed during pregnancy, rather than have an onset in the post-natal period. CONCLUSION: Over one-quarter of mothers in a rural sub-district of Pakistan suffer from depression shortly before and after childbirth. Rapidly changing traditional family structures and practices may be increasing the risk of depression in many women. Recognizing and treating depression should be initiated during the antenatal, rather than post-natal period.     

The risk factors for depression in first myocardial infarction patients

BACKGROUND: Depression affects outcome following myocardial infarction but the risk factors for such depression have been little studied. This study considered whether the causes of depression occurring before and after myocardial infarction were similar to those of depression in the general population. METHOD: Consecutive patients admitted to hospital following their first myocardial infarction were interviewed with the Schedule for Clinical Assessment in Neuropsychiatry to detect psychiatric disorders and the Life Events and Difficulties Schedule to assess recent stress. Participants completed the Hospital Anxiety and Depression Scale (HADS) at entry to the study and 1 year later and the risk factors associated with a high score at both times were assessed. RESULTS: Of 314 (88% of eligible) patients who were recruited, 199 (63%) were male and 63 (20%) had depressive disorders. Logistic regression identified the following as independently associated with depressive disorder that had been present for at least I month before the myocardial infarction: younger age, female sex, past psychiatric history, social isolation, having marked non-health difficulties and lack of a close confidant. At follow-up 269/298 (90%) responded; of 189 participants not depressed at first assessment, 39 (21%) became depressed by the 1 year follow-up. Logistic regression identified frequent angina as the only significant predictor of raised HADS scores at 12 months. CONCLUSIONS: Depression developing during the year following myocardial infarction does not have the same risk factors as that which precedes myocardial infarction. Further clarification of the mechanisms linking depression to poor outcome may require separation consideration of pre- and post-myocardial infarction depression, and its risk factors.     

Outcome of prenatal depression and risk factors associated with persistence in the first postnatal year: prospective study from Rawalpindi, Pakistan

BACKGROUND: Rates of prenatal and postnatal depression in developing countries are high. Prolonged depression during the postnatal period is associated with impaired infant growth and development. Little is known about the factors predicting the persistence of prenatal depression beyond the first few postnatal months. METHODS: From a sample of 701 women in a rural sub-district of Pakistan, the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) was used to identify those with ICD-10 depressive disorder in the third trimester of pregnancy (n=160). Depressed women were re-assessed at 3, 6 and 12 months postnatal. Persistently depressed women (depressed at all time points) were compared with the remainder. Psychiatric symptoms, disability and life events were measured using the Self-Reporting Questionnaire (SRQ), Brief Disability Questionnaire (BDQ), and a modified Life Events Checklist. RESULTS: Of 129 mothers who completed follow-up, 73 (56%) were depressed at all points of assessment. These persistently depressed mothers had higher SRQ and BDQ scores prenatally and had experienced more life events in the year preceding the third pregnancy trimester than the mothers whose depressive disorder resolved (none received treatment). Persistent depression was significantly associated also with poverty, having 5 or more children, an uneducated husband and lack of a confidant or friend. On multivariate analysis, higher SRQ score and poverty during pregnancy predicted persistent depression. LIMITATIONS: The sample was from one rural sub-district only. We did not assess the women for physical conditions such as anaemia and thyroid-deficiency. CONCLUSION: Women who are poor and have more psychological symptoms during pregnancy are more likely to remain depressed one year after giving birth. This study highlights the need for developing mechanisms of early identification and suitable psychosocial interventions to minimise the damaging effects of persistent postnatal depression in poor communities.     

The validation of personal health questionnaire amongst people of Pakistani family origin living in the United Kingdom

BACKGROUND: The Personal Health Questionnaire (PHQ) was developed to screen for depressive disorder in an English speaking population. Its validity in Urdu speaking people of Pakistani family origin living in UK is yet to be established. METHODS: The PHQ was used to screen for depression in a two phase primary care based study of depressive disorder in people of Pakistani family origin residing in Manchester, UK. A proportion of high scorers (PHQ> or =7) and a random selection of low scorers (PHQ 0-6) were interviewed with the Psychiatric Assessment Schedule (PAS) to confirm caseness (ID> or =5). A receiver operator characteristic curve (ROC) analysis was carried out to confirm the optimum threshold value. RESULTS: The PHQ was used to screen 218 subjects with cut off of PHQ> or =7. 46 high scorers and 31 low scorers were interviewed in second stage using PAS. At this threshold PHQ has a sensitivity of 70.4% and specificity of 89.3%. CONCLUSIONS: Findings of this study confirm high sensitivity and specificity of PHQ amongst people of Pakistani family origin. It can be used as a screening instrument to detect depression in Urdu speaking population in UK.     

Prevalence,Work-Loss Days and Quality of Life of Community Dwelling Subjects with Depressive Symptoms

The nationwide prevalence of major depressive disorder in Korea is lower than most countries, despite the high suicide rate. To explain this unexpectedly low prevalence, we examined the functional disability and quality of life in community-dwelling subjects with significant depressive symptoms not diagnosable as depressive disorder. A total of 1,029 subjects, randomly chosen from catchment areas, were interviewed with the Center for Epidemiologic Studies Depression scale, Mini International Neuropsychiatric Interview, WHO Quality of Life scale, and the WHO Disability Assessment Schedule. Those with scores over 21 on the depression scale were interviewed by a psychiatrist for diagnostic confirmation. Among community-dwelling subjects, the 1-month prevalence of major depressive disorder was 2.2%, but the 1-month prevalence of depressive symptoms not diagnosable as depressive disorder was 14.1%. Depressive disorders were the cause of 24.7% of work loss days, while depressive symptoms not diagnosable as depressive disorder were the cause of 17.2% of work loss days. These findings support the dimensional or spectrum approach to depressive disorder in the community and might be the missing link between the apparent low prevalence of depressive disorder and high suicide rate in Korea.     

The general population prevalence of non-organic psychiatric disorders in subjects aged 85 years and over.

The prevalence of psychiatric disorders was investigated in all inhabitants over 85 years of age (N = 1259), residing in Leiden, The Netherlands. The study design consisted of two phases. In the first phase the Mini-Mental State Examination (MMSE) and the 12-item version of the General Health Questionnaire (GHQ-12) were used to screen for potential cases; in the second phase all potential cases and a sample of the non-cases were interviewed with the Geriatric Mental State Schedule (GMS). DSM-III diagnoses were made based on the GMS and on information obtained from caregivers. There was a high prevalence of organic disorders of 31% (95% CI: 27-35%). The estimated overall prevalence rate for functional disorders was 8% (95%) CI: 4-12%). This is an underestimate because organic and functional disorders are mutually exclusive in DSM-III. The prevalence rate estimated for the population at risk for functional disorders (i.e. the total population minus the organic cases) was 12% (95% CI: 6-18%). This is very similar to prevalence rates for functional disorders found in population based surveys in younger age groups. Therefore, in contrast with the dementias, there appears to be no increase with age for the functional disorders.     

Anxiety disorders comorbidity in bipolar I, bipolar II and unipolar major depression: results from a population-based study in Hungary

BACKGROUND: The aim of this study was to analyze the lifetime comorbidity between DSM-III-R anxiety disorders in separate subgroups of patients with major depression, bipolar II and bipolar I disorder in a community sample of a Hungarian population. METHODS: Randomly selected subjects (aged between 18 and 64 years, N=2953) were interviewed by the Diagnostic Interview Schedule (DIS) which generated DSM-III-R diagnoses. RESULTS: The prevalence of generalized anxiety disorder, agoraphobia and simple phobia was the highest among bipolar II patients (20.8, 37.5 and 16.7%, respectively), social phobia was most prevalent in (nonbipolar) major depression (17.6%), while the rate of panic disorder was the same in the (nonbipolar) major depressive and bipolar II subgroups (12.4 and 12.5%, respectively). Bipolar I patients showed a relatively low rate of comorbidity. CONCLUSIONS: The findings support previous results on the particularly high rate of lifetime comorbidity between anxiety disorders and unipolar major depression and particularly bipolar II illness. LIMITATIONS: Underestimation of the prevalence of bipolar II disorder by the diagnostic methodology used, resulting in a small number of bipolar II cases, lack of analysis of data by gender, no data on obsessive-compulsive disorder.     

Understanding cross-national differences in depression prevalence

BACKGROUND. Previous epidemiological studies indicate large cross-national differences in prevalence of depression. METHODS: At 15 centres in 14 countries. 25,916 primary care patients were screened for common mental disorders. A stratified random sample of 5,447 primary care patients completed a baseline diagnostic assessment and 3,197 completed a 12-month follow-up assessment. Psychiatric symptoms and diagnoses were assessed using the Composite International Diagnostic Interview (CIDI). Interviewer-rated disability was assessed using the Social Disability Schedule (SDS). RESULTS: Prevalence of current major depression varied 15-fold across centres. When centres were divided into three groups according to prevalence rates, the symptom pattern or latent structure of depressive illness was generally similar at low-, medium-, and high-prevalence centres. Depression was universally associated with disability, but this association varied significantly (t = 3.51, P = 0.0005) across centres. At higher-prevalence centres, depression was associated with lower levels of impairment. At 1 year follow-up, higher prevalence centres had both significantly higher rates of depression onset (t = 3.11, P = 0.002) and higher rates of persistence among those depressed at baseline (t = 2 49, P = 0.013). CONCLUSIONS: Large cross-national variations in depression prevalence cannot be attributed to 'category fallacy' (cross-national differences in the nature or validity of depressive disorder). Use of identical measures and diagnostic criteria may actually identify different levels of depression severity in different countries or cultures. Cross-national differences in the onset and outcome of depression may reflect either true prevalence differences or differences in diagnostic threshold.     

Personality disorder, depression and functioning: results from the ODIN study

BACKGROUND: There is little information of the prevalence of personality disorder (PD) in those with depressive disorder in community samples; neither is there any data on the impact of PD on service utilisation or outcome in this setting. METHODS: A two stage screening study to identify cases of depressive disorder using SCAN in five European countries. Personality assessed 6 months after the diagnostic interview. Follow-up for 1 year using symptom and social function measures. RESULTS: Personality disorder is present in 22% of a community sample with depressive disorders but the range varied from 13.7% to 33.3% across countries. Cluster C formed 43% of the total. Long-term psychotropic drug use was more common in the PD group even after depression was controlled. Those with PD had higher symptom scores at the outset and, although the PD group was more likely to be cases at follow-up, this disappeared when the depression score was co-varied. Only initial social function predicted outcome at 6 and 12 months. LIMITATIONS: The use of a non-treatment seeking population may limit the application of the findings to clinical populations. CONCLUSIONS: PD is common even in a non-treatment seeking population with depressive disorder. It impacts upon outcome at 6 and 12 months but this is related to the initial severity of depressed mood. Social function is the only independent predictor of outcome and should be assessed separately.     

HIV and depression: 2008 review and update

Since the earliest days of the AIDS epidemic, clinicians have been concerned about the prevalence of depression among their patients. Epidemiologists, psychiatrists, psychologists, sociologists, and a broad array of other specialists have studied this topic, trying to determine the prevalence of depressive disorders and depressive symptoms as well as antecedents, correlates, and consequences. This review addresses the methodologic difficulties in determining depression prevalence, major findings regarding rates of disorder and correlates among different segments of the HIV community, effects of depression on HIV illness progression, psychopharmacologic and psychotherapeutic treatment findings, and behavioral effects of depression, such as its impact on medication adherence, employment, and risk behavior. Finally, the article summarizes international studies of depression prevalence in developing countries and the challenges regarding cross-national diagnostic definitions and measures.     

Cross-cultural and social diversity of prevalence of postpartum depression and depressive symptoms

BACKGROUND: The prevalence of postpartum depression (PPD) is currently considered to be 10-15%. Most studies were performed with a brief unidimensional instruments (mostly the Edinburgh Postnatal Depression Scale-EPDS) with focus on depression and not on other symptoms and disorders. Most cited studies were conducted in Western economically developed countries. METHODS: We reviewed the literature on prevalence of postpartum depression and depressive symptoms in a wide range of countries. RESULTS: 143 studies were identified reporting prevalence in 40 countries. It is demonstrated that there is a wide range of reported prevalence of PPD ranging from almost 0% to almost 60%. In some countries like Singapore, Malta, Malaysia, Austria and Denmark there are very few reports of PPD or postpartum depressive symptoms, whereas in other countries (e.g. Brazil, Guyana, Costa Rica, Italy, Chile, South Africa, Taiwan and Korea) reported postpartum depressive symptoms are very prevalent. CONCLUSIONS: We believe that the widely cited mean prevalence of PPD-10-15% is not representative of the actual global prevalence and magnitude of the problem, due to the wide range of reports. The variability in reported PPD might be due to cross-cultural variables, reporting style, differences in perception of mental health and its stigma, differences in socio-economic environments (e.g. poverty, levels of social support or its perception, nutrition, stress), and biological vulnerability factors. The elucidation of the underlying processes of this variability as well as the diversity of postpartum normal versus abnormal expressions of symptoms may contribute to better understanding of the diversified ante, peri- and postpartum phenomena.     

Insomnia and hypersomnia associated with depressive phenomenology and comorbidity in childhood depression

STUDY OBJECTIVES: To examine sleep disturbance (insomnia and hypersomnia) and associated clinical profiles among depressed children and adolescents in terms of illness history, depressive severity, depressive phenomenology, and psychiatric comorbid disorders. DESIGN: Clinical profiles from standardized clinical evaluations were compared. SETTING: Twenty-three mental health facilities in Hungary between April 2000 and December 2004. PATIENTS AND MEASUREMENTS: Five hundred fifty-three children with a current episode of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition major depressive disorder: 55% were boys, mean age was 11.7 years (SD = 2.0, range = 7.3-14.9), and 94% were Caucasian. Sleep and depressive symptoms were assessed with the Interview Schedule for Children and Adolescents-Diagnostic Version. INTERVENTIONS: N/A. RESULTS: Of the total sample, 72.7% had sleep disturbance: 53.5% had insomnia alone, 9.0% had hypersomnia alone, and 10.1% had both disturbances. Depressed girls were more likely to have sleep disturbance than boys (77.0% vs 69.2%, p < .05), but age had no significant effects. Compared with children without sleep disturbance, sleep-disturbed children were more severely depressed and had more depressive symptoms and comorbid anxiety disorders. Across sleep-disturbed children, those with both insomnia and hypersomnia had a longer history of illness, were more severely depressed, and were more likely to have anhedonia, weight loss, psychomotor retardation, and fatigue than were those with either insomnia or hypersomnia. CONCLUSION: Clinical profiles differ between depressed children without and with sleep disturbance, with those presenting insomnia plus hypersomnia being most severely depressed. Differentiating depressed children with different sleep disturbances may have important implications for research efforts on the etiology and therapeutics of child depression.     

Is sex necessarily a risk factor to depression?

To isolate and quantify possible determinants of any increased prevalence of depressive disorders in women we studied a select group of men and women, initially similar in terms of a number of putative social determinants of depression, and reviewed the sample five years later when social role diversity was anticipated. We used the Diagnostic Interview Schedule (DIS) to generate DSM-III and RDC diagnoses to estimate lifetime depressive disorders, and established (via corroborative reports) the likely accuracy of those data. Despite lifetime depression being a relatively common experience, no significant sex differences in depressive episodes were demonstrated, suggesting the possible irrelevance of biological factors in determining any sex difference. As there was not major social role divergence over the five year study, we interpret the lack of a sex difference as a consequence, and suggest that findings support the view that social factors are of key relevance in determining any female preponderance in depression described in general population studies.     

Child and adolescent clinical features as forerunners of adult-onset major depressive disorder: retrospective evidence from an epidemiological sample

BACKGROUND: Adult-onset cases of DSM-III-R major depressive disorder (MDD) often have had a history of mood disturbances and allied clinical features during childhood or adolescence. This study seeks to illuminate these early-life disturbances, as recalled and reported by adult-onset MDD cases (i.e. those whose first episode of MDD occurred after age 18) and non-cases. METHODS: Our research group has re-assessed survivors in the Baltimore Epidemiologic Catchment Area (ECA) community sample roughly 13.5 years after first diagnostic assessments in 1981. Of the 1920 participants, 150 were found to have a history of adult-onset MDD; 1755 were sub-threshold with respect to DSM criteria or reported few or no depression-related problems. Survival analysis was used to plot and study the cumulative occurrence of each clinical feature of depression from age 6 through 18 years for cases of adult-onset MDD versus non-cases. RESULTS: The earliest and most frequently occurring forerunners of adult-onset MDD were persistent depressed mood, anhedonia, feelings of worthlessness, and thoughts of death or suicide, with persistent anhedonia and worthlessness having a special prognostic value. One-third of adult-onset cases of MDD reported at least one clinical feature before age 19 versus only 7.3% of non-cases. LIMITATIONS: The study's estimates are based on retrospective recall, although a life chart methodology sought to reduce recall inaccuracies. CONCLUSIONS: The ECA follow-up sample data, though based on retrospection, provide new details about early forerunners of adult-onset depression from a sample of survivors. When they appear in children or adolescents, persistent anhedonia and persistent feelings of worthlessness merit special attention. These two clinical features, in particular, may help predict later risk of adult-onset major depression.     

Emergence of Depressive Symptoms from Kindergarten to Sixth Grade

This study documents the emergence of symptoms of anxiety and depression in a community sample of school-age children and describes the temporal progression of symptoms leading to depressive episodes. Caregivers of 468 seventh graders reported retrospectively the manifestation of 14 symptoms of depression and anxiety in their children from kindergarten through sixth grade. The sample was balanced by sex and reflected the racial and economic diversity of the urban school district. Childhood period prevalence was calculated for each symptom, and discrete time survival analyses compared likelihoods of early symptom emergence in children who did and did not meet diagnostic criteria for major depressive disorder (MDD) by ninth grade. Symptom prevalence ranged between 20% (excessive guilt) and 50% (concentration problems) during the elementary school years. The 4-year period prevalence of MDD was 8.9%, 95% confidence interval [6.5%, 12.1%]. Low energy, excessive worry, excessive guilt, anhedonia, social withdrawal, and sadness or depressed mood were each associated with a significantly higher likelihood of onset of MDD. Compared to girls, boys were more likely to exhibit sad mood, fatigue, and trouble concentrating. Children who later met criteria for MDD demonstrated a significantly higher likelihood of showing core features of depressive and anxiety disorders during their elementary school years. The findings underscore the importance of recognizing early signs and developing interventions to help children manage early symptoms and prevent later psychiatric illness.     

Social functioning in community residents with depression and other psychiatric disorders: results of the New Haven Epidemiologic Catchment Area Study

Social functioning was compared among 4913 community participants with current depression, past depression, other psychiatric disorders and no psychiatric history, from the New Haven Epidemiologic Catchment Area Wave I survey. Respondents with current major depressive disorder (1.5%) (based on the Diagnostic Interview Schedule) reported significantly poorer intimate relationships and less satisfying social interactions than respondents with past depression or other current disorders. Respondents with no psychiatric history (77%) reported significantly more active and satisfying social interactions than persons with any psychiatric disorder. These social functioning and depression associations were similar among males and females, and corroborated results from patient samples.

Development and validation of a questionnaire for anxiety and depression in Pakistan

BACKGROUND: Currently clinicians and researchers in Pakistan have to use translated western instruments to screen for anxiety and depressive disorders. This study investigated the local idioms of emotional distress in Pakistan to develop a culturally valid and easy-to-use instrument to screen for common mental disorders in general clinical settings. METHODS: A systematic survey was conducted of psychiatric case notes of patients attending clinics in Peshawar and Lahore, diagnosed with anxiety or depressive disorders, to identify the range of common idioms of psychological distress. A pilot version of the questionnaire was refined and validated among a composite sample of 330 patients in inpatient, outpatient and rural community settings. ICD-10 Diagnostic Criteria for Research were used to define cases and patients' relatives acted as normal controls. RESULTS: The pilot version of the questionnaire was reduced to 42 items based on odds ratios between cases and controls. Anxiety symptoms were generally reported by depressed patients, but not vice versa. Finally 30 items were selected, in two sub-scales. This final version achieved sensitivity, specificity, and positive and negative predicted values of over 90% when comparing cases and controls. LIMITATIONS: This questionnaire was based on what patients tell doctors and may not capture the entire repertoire of local idioms of distress. The validation study was conducted only in an Urdu/Punjabi speaking population, in Lahore and surrounding areas. CONCLUSIONS: The Pakistan Anxiety and Depression Questionnaire consists of an anxiety/depression scale and a depression scale, each of 15 items. It demonstrates excellent validity as screening instrument for anxiety and depressive disorders in clinical settings in Pakistan.     

Recognition of childhood depression: personal reminiscences

Prior to 1970, childhood depression was not considered a valid clinical entity by American psychiatrists. One of the early clues was provided in the 1950s by the author's observation of depressive symptoms in children and young adolescents with undescended testicles. This finding was extended to children with several chronic diseases, many of whom exhibited depressive symptoms as well. Eventually, depressive symptomatology was found in children without any physical disorders. This was followed by the introduction of a diagnostic instrument, called the Children's Affective Rating Scale (CARS), later converted into a more formal system called the Child Assessment Schedule (CAS). A provisional classification of childhood depression was published in 1972. Our examination of children with depressive disorders has revealed several modes of family interaction, of which the most important were: separation from important love objects; depreciation and rejection; and affective disorders in parents. Several children with bipolar disorder stimulated our interest in this disorder and led to a pilot study of children of bipolar, lithium-responding parents. Some of these children with bipolar illness had a clear-cut response to lithium and were strong augmenters of the average evoked potentials (EPs). Next, our group investigated the urinary excretion of norepinephrine and its metabolites in chronically depressed children who differed from a normal control group. The foregoing studies, along with major contributions by other child psychiatrists, eventually led to the acceptance of childhood depression as a clinical entity in US psychiatry. The acceptance of juvenile bipolar disorder had to await further research by a new generation of child and adult psychiatrists.
