Maternal depression and low maternal intelligence as risk factors for malnutrition in children: a community based case-control study from South India.

AIMS: To determine whether current and postpartum maternal depression and low maternal intelligence are risk factors for malnutrition in children. METHODS: In rural South India 72 children with malnutrition were identified from a central register; 72 controls were matched for age, gender, and residence. RESULTS: Major depression in the postpartum period (OR 5.0, 95% CI 1.0 to 24.0), current major depression (OR 3.2, 95% CI 1.1 to 9.5), and low maternal intelligence (OR 3.8, 95% CI 1.3 to 11.1) were associated with malnutrition in the child. Low birth weight (OR 2.9, 95% CI 1.2 to 6.8) was also significantly associated with infant malnutrition. Conditional logistic regression adjusting for all other determinants yielded the following results: major depression during the postpartum period (OR 7.8; 95% CI 1.6 to 38.51), current major depression (OR 3.1; 95% CI 0.9 to 9.7), low maternal intelligence (OR 4.6; 95% CI 1.5 to 14.1), and low birth weight (OR 2.7; 95% CI 2.5 to 6.8). The interactions between current maternal depression and low birth weight and between postpartum depression and low maternal intelligence were statistically significant. The level of maternal intelligence was associated with nutritional status. The severity of malnutrition was also significantly associated with major depression during the postpartum period and low maternal intelligence. CONCLUSION: There is evidence for an association between postpartum maternal depression, low maternal intelligence, and low birth weight with malnutrition in children aged 6-12 months.

A cohort study of male subjects attending an alcoholics anonymous program in India: one-year follow-up for sobriety.

OBJECTIVE: The objective of this study was to follow up a cohort of subjects who completed detoxification treatment and a deaddiction program based on the Alcoholics Anonymous (AA) model. The factors associated with complete abstinence were investigated. METHOD: Patients (187 men) admitted consecutively to an addiction facility, who fulfilled the DSM-IV criteria for alcohol dependence, were recruited for the study. Patients with major psychopathology were excluded from the cohort. The program was based on the principles of AA. The final outcome at 1 year was determined by visiting the patient and talking to the family and members of the local AA group. RESULTS: Of the 187 initially recruited, five were excluded due to the presence of major psychopathology, one committed suicide and seven could not be traced. Of the 174 patients followed up, 58 (33.3%) remained sober (complete abstinence for the past year) at 1 year. Patients coming from distant places and those with follow-up workers in their localities fared better than those from the local area and those from towns where there was no one to motivate them to continue with AA meetings. These variables were significantly associated with sobriety even after adjusted for other confounders using multivariate techniques. CONCLUSIONS: A third of the cohort remained sober at 1-year follow-up. The patients' initial motivation and continued support once they returned to their communities were associated with being sober at follow-up.

Validation of the Routine Assessment of Patient Progress (RAPP) in patients with psychosis in South India.

The aim of the study was to validate the Routine Assessment of Patient Progress (RAPP), an instrument for assessment by nurses, among patients with psychosis in South India. One hundred consecutive patients with psychosis admitted to the Department of Psychiatry, Christian Medical College, Vellore, India, were assessed on day five and day 19 using the RAPP, the PANSS, and the CGI scales. The correlation of the RAPP with the other scales, its change over time, the inter-rater reliability, and factor structure were assessed. The subscales of RAPP correlated significantly with those of the other scales at intake and at follow-up. The RAPP scores changed significantly after treatment. Its inter-rater reliability as measured by the intra-class correlation coefficient was 0.98. The Cronbach's alpha, used to measure the internal consistency of the scale, was 0.87. The split-half reliability (Spearman-Brown) was 0.89. Principal component analysis with varimax rotation revealed six factors, which explained 67.4% of the variance. Items related to life skills explained a major proportion of the variance. The good psychometric properties, concurrent validity, high inter-rater reliability and sensitivity to change make it a useful instrument for nurses to employ to assess patients with psychoses.

Explanatory models of psychosis among community health workers in South India.

OBJECTIVE: To examine commonly held indigenous beliefs about mental illness, which often differ markedly from the biomedical models, among community health workers in rural South India. METHOD: Indigenous beliefs about chronic psychosis were elicited from community health workers. The Short Explanatory Model Interview formed the basis of the interview. RESULTS: A variety of indigenous beliefs, which contradicted the biomedical model, were elicited. A significant proportion of health workers did not recognize chronic psychosis as a disease condition, believing that it was caused by black magic, evil spirits and poverty, and felt that doctors could not help. CONCLUSION: The results of the study suggest that training programmes should elicit and discuss local beliefs prior to the teaching of the biomedical model of mental disorders.

Common mental disorders among primary care attenders in Vellore, South India: nature, prevalence and risk factors.

OBJECTIVE: The study examined the nature and prevalence of and the factors associated with common mental disorders in primary care in Vellore, South India. METHOD: Consecutive attenders (N = 327) to a primary health care facility were recruited. RESULTS: One hundred and eleven (33.9%) subjects satisfied criteria for common mental disorders. Depression was the common presentation (83.8%). Indicators of low socio-economic status (being in debt, inability to buy food, having less than three square meals per day) and illiteracy were significantly associated with caseness. CONCLUSIONS: Subjects with common mental disorders are commonly seen in primary health care settings. Illiteracy and poverty are associated with caseness. Primary health care research and policy needs to focus on common mental disorders.

A randomised controlled trial of an educational intervention for depression among Asian women in primary care in the United Kingdom.

OBJECTIVE: To determine the effect of patient education on patient perspectives and outcome of depression in a sample of Asian women in primary care. DESIGN: A randomised, clinical trial of "patient education" versus "usual care". SETTING: A general practice in London, which has a high proportion of Asians. SUBJECTS: Seventy patients with psychiatric morbidity (a score of 3 or more on the General Health Questionnaire 12) were recruited for the trial. OUTCOME MEASURES: Patient's explanatory models of illness (the patient's perspective on depression; recognition of depression as illness and recommend a medical intervention for this condition) and psychiatric morbidity at follow-up after two months were the primary outcome measures. RESULTS: One hundred and fifty-five women of Asian decent were contacted. One hundred and forty-eight (95.5%) agreed to take part in the study. Seventy (47.3%) were classed as cases of common mental disorder using the General Health Questionnaire 12. Thirty-five were randomly allocated to receive education about the nature, causes, prevalence and treatment of depression, 35 did not receive such information. There were no statistical differences between the two groups on baseline characteristics. Sixty-six (94.3%) subjects were followed up at two months. An intention to treat analysis showed that there was no difference in explanatory model measures between the two groups at the end of the study. However, more patients who received education were no longer cases (a score of 2 or less on the GHQ) (15/35; 42.9%) compared to controls (7/35; 20%) (p < 0.05) as did those with lower GHQ scores at entry (p < 0.03). Receipt of educational intervention (OR 3.4; 95% CI 1.01, 11.5) and lower GHQ scores at entry (OR 7.1; 95% CI 1.05, 30.2) remained significantly associated with recovery after adjusting for baseline variables using logistic regression. CONCLUSIONS: Patients with common mental disorders, especially those with milder forms of the condition, who received the educational material had a higher recovery rate than patients who do not receive such education. The mechanism for this improvement was unclear, not being reflected in patient's apparent understanding of depression nor explained by change in general practitioner's response. The results of this study need to be replicated.

Attempted suicide in west London, II. Inter-group comparisons.

BACKGROUND: Previous studies of attempted suicide have suggested that cultural and social factors play a significant role in the causation of deliberate self-harm. METHOD: In order to measure elements of culture conflict two inter-group comparisons were undertaken. In the first, 27 Asian women who had presented to hospital services following attempted suicide (Asian group) were matched with a group of similar age Asian women attending GP surgeries for other reasons (Asian GP attenders group). The second comparison was between the Asian and 46 White attempters. RESULTS: On comparing Asian attempters with Asian GP attenders group the former were more likely to have a history of previous suicidal behaviour, to have a psychiatric diagnosis, and be unemployed. Their parents were more likely to have arrived in the United Kingdom at an older age. In addition, those who attempted suicide were more likely to have been in an inter-racial relationship and to have changed religions. In the second inter-group comparison, the characteristics of Asian and White suicide attempt patients were examined. White attempters were more likely to have mental illness, and were more likely to use alcohol as part of the method of attempted suicide. By contrast, Asian attempters had experienced life events pertaining to relationships, took fewer tablets and yet expressed greater regret at not succeeding in the attempt. CONCLUSIONS: Although numbers are small, social stress and other cultural factors play an important role in the act of deliberate self-harm.

The comparison of latent variable models of non-psychotic psychiatric morbidity in four culturally diverse populations.

BACKGROUND: Factor analysis has been employed to identify latent variables that are unifying constructs and that parsimoniously describe correlations among a related group of variables. Confirmatory factor analysis is used to test hypothesized factor structures for a set of variables; it can also, as in this paper be used to model data from two or more groups simultaneously to determine whether they have the same factor structure. METHOD: Non-psychotic psychiatric morbidity, elicited by the Revised Clinical Interview Schedule (CIS-R), from four culturally diverse populations was compared. Confirmatory factor analysis was employed to compare the factor structures of CIS-R data sets from Santiago, Harare, Rotherhithe and Ealing. These structures were compared with hypothetical one and two factor (depression-anxiety) models. RESULTS: The models fitted well with the different data sets. The depression-anxiety model was marginally superior to the one factor model as judged by various statistical measures of fit. The two factors in depression-anxiety model were, however, highly correlated. CONCLUSIONS: The findings suggest that symptoms of emotional distress seem to have the same factor structure across cultures.

The development of the Short Explanatory Model Interview (SEMI) and its use among primary-care attenders with common mental disorders.

BACKGROUND: Recent anthropological studies have documented the importance of understanding the relation of culture to the experience of mental illness. The use of interviews that elicit explanatory models has facilitated such research, but currently available interviews are lengthy and impractical for epidemiological studies. This paper is a preliminary report on the development of a brief instrument to elicit explanatory models for use in field work. METHOD: The development of the SEMI, a short interview to elicit explanatory models is described. The interview explores the subject's cultural background, nature of presenting problem, help-seeking behaviour, interaction with physician/healer and beliefs related to mental illness. RESULTS: The SEMI was employed to study the explanatory models of subjects with common mental disorders among Whites, African-Caribbean and Asians living in London and was also used in Harare, Zimbabwe. Data from its use in four different ethnic groups is presented with the aim of demonstrating its capacity to show up differences in these varied settings. CONCLUSIONS: The simplicity and brevity of the SEMI allow for its use in field studies in different cultures, data can be used to provide variables for use in quantitative analysis and provide qualitative descriptions.

Common mental disorders, explanatory models and consultation behaviour among Indian women living in the UK.

Women of Indian origin are said to have a lower rate of recognized common mental disorders and a higher frequency of consultation in primary care than white British. The aim of this study was to evaluate factors, including explanatory models (patient perspectives) of illness, associated with common mental disorders and with frequency of consultation among women of Indian origin in primary care. The investigation was conducted in a general practice in West London with a large Indian population. Consecutive woman attenders of Indian descent were screened with the General Health Questionnaire-12 to identify probable cases of psychiatric morbidity. 100 patients were interviewed with the Revised Clinical Interview Schedule (CIS-R), a specific tool for the diagnosis of common mental disorders, and the Short Explanatory Model Interview, which elicits the individual's conceptualization of his or her illness. Those patients who satisfied CIS-R criteria were classified as 'cases', the others as 'controls'. Common mental disorders were documented in 30% of patients. The general practitioner's diagnosis of common mental disorders had a sensitivity of 17% and a specificity of 91%. Individuals with common mental disorders had a higher frequency of consultation (P = 0.017), were less likely to see depression as an indication for medical intervention and were more likely to withhold some of their concerns from the general practitioner. Incorrect diagnosis by the GP was most likely to occur when patients did not disclose all their complaints. These associations were all statistically significant after adjustment for possible confounders by multiple linear and logistic regression. Women of Indian origin in this sample had rates of common mental disorders similar to those in other UK populations. Differing conceptualizations of common mental disorders may contribute to their underrecognition in women of Indian origin.

The validation of the 12-item General Health Questionnaire among ethnic Indian women living in the United Kingdom.

BACKGROUND: The General Health Questionnaire (GHQ) has been validated in different languages and cultures and in diverse settings. However, the validity of the 12-item version, increasingly used for screening for psychiatric morbidity in primary care, has not been established among ethnic Indians living in the United Kingdom. METHODS: The GHQ-12 was used to screen for psychiatric morbidity in a study of patterns of consultation and explanatory models of mental illness in a general practice in West London. All individuals who scored 2 or more and an equal number of individuals who scored 0 or 1 were interviewed using the Revised Clinical Interview Schedule (CIS-R) to confirm psychiatric morbidity. Hindi versions of the both these instruments were also employed. Thresholds of GHQ were compared against the standard of the CIS-R using the recommended threshold of 12 and above as indicating caseness. A receiver operator characteristic curve was drawn to obtain the best threshold value for screening. RESULTS: The optimal threshold for screening as assessed by receiver operator characteristic analysis was 2/3. This threshold had a sensitivity of 96.7% and a specificity of 90%. CONCLUSIONS: The sensitivity and specificity of the 12-item General Health Questionnaire among women of ethnic Indian origin living in the United Kingdom is high. It can be employed as a screening instrument to identify individuals with psychiatric morbidity in this population.

Depression in individuals with spinal cord injury: methodological issues.

The methodological problems in research related to depression in individuals with spinal cord injury (SCI) are examined. These include relation to normal emotional reactions following injury, the use of physical and vegetative symptoms in the diagnosis of depression, the utilisation of rating scales primarily designed for use in psychiatric populations, the heterogeneity of patients with SCI, the role of preexisting psychiatric morbidity, the selection of controls for comparison and the necessity for multivariate statistical approaches to analysis. The issues and possible solutions are discussed.
