No. of bitstreams: 1 Alessandra Pontes Peres.pdf: 298492 bytes, checksum: 617312d66562613c89c4978c1f86b08e (MD5) Previous issue date: 2010-01-26 / Objective: The present study assessed the social support relation to gestational depression, and still other possible factors associated to depression, such as age of the pregnant woman, presence of a companion, schooling and income. Method: Cross-section study with adolescent pregnant women, aged 10-19, between 20th and 32nd. gestation week. The sample was collected in Basic Health Units (BHU) and three specialized outpatient clinics, in the city of Pelotas. Depressive disturb was assessed by means of a standardized diagnostic interview, Mini International Neuropsychiatric Interview (MINI), compatible with DSM-IV and CID-10 criteria. In order to assess Social Support, the Medical Outcome Study (MOS) scale was utilized. A self-applied and secret questionnaire was utilized for other variables. Results: The sample included 223 pregnant women. Social support was significantly associated to depression (outcome), presenting a p>0,001. The variables: age, presence of a companion, income, and schooling did not associate to the depression diagnosis. Conclusion: To assess the perception of social support considered by the adolescents can provide important information to identify pregnant women under depression risk / Objetivo: Este estudo avaliou a relação do suporte social com a depressão gestacional, e ainda outros possíveis fatores associados à depressão como a idade da gestante, presença de companheiro, escolaridade e renda. Método: Estudo transversal com gestantes adolescentes em idade de 10 a 19 anos, estando entre a 20ª e a 32ª semanas gestacionais. A amostra foi coletada em Unidades Básicas de Saúde (UBSs) e três ambulatórios especializados, na cidade de Pelotas. O transtorno depressivo foi avaliado através de uma entrevista diagnóstica padronizada, Mini Internacional Neuropsychiatric Interview (MINI), compatível com os critérios do DSM-IV e CID-10. Para avaliar o Suporte Social foi utilizada a escala Medical Outcomes Study (MOS). Para outras variáveis foi utilizado um questionário autoaplicado e sigiloso. Resultados: A amostra contou com 223 gestantes. O suporte social esteve associado significativamente com a depressão (desfecho), apresentando um p<0,001. As variáveis idade, presença de companheiro, renda e escolaridade não estavam associadas com o diagnóstico de depressão. Conclusão: Avaliar a percepção do suporte social considerado pelas adolescentes pode fornecer informações importantes para identificar gestantes que estejam em risco para depressão

Health-related quality of life, symptoms experience and perceived social support among patients with liver cirrhosis : a cross-sectional study in Egypt

Youssef, Naglaa F. A. January 2013 (has links)
Background: Liver cirrhosis is a global health problem and a national health problem in Egypt. There is a lack of literature on Health-Related Quality of Life (HRQOL) and symptoms experience of liver disease and cirrhotic patients in Middle East, particularly in Egypt. Aims: This PhD had three major aims: First aim: To describe HRQOL of Egyptian liver cirrhotic patients and to identify and evaluate the factors associated with (HRQOL) physical and mental health domains. Second aim: To explore and describe experienced symptoms (prevalence, severity and hindrance) in Egyptian cirrhotic patients and to identify and evaluate factors associated with symptoms severity and symptoms hindrance (distress). Third aim: To explore and describe how cirrhotic patients in Egypt perceive social support from spouse, family and friends and to identify and evaluate factors associated with general perceived social support. Method: A cross-sectional study with a convenience sample of 401 patients from three hospitals in Cairo, Egypt, was conducted between June and August 2011. Patients were interviewed to complete a background data sheet, Short Form-36v2 (SF-36), the Liver Disease Symptom Index (LDSI)-2.0 and the Multidimensional Scale of Perceived Social Support (MSPSS). Results: Findings for first aim: The findings showed that all domains and component summary scores [Physical component summary score (PCS) and mental component summary score (MCS)] of the generic SF-36 were below the norm (cut-off score 50), suggesting that patients with liver cirrhosis in Egypt have poor HRQOL. About 87.2% of the patients rated their general health as poor or fair, which means the majority of these patients have low perceived general health. Many socio-demographic and medial factors were shown to be significantly associated with perceived HRQOL. Women, illiterate and unemployed people, and patients with frequent hospitalisation had poor PCS and MCS, while patients with advanced disease stage, increasing number of comorbidities and complications and those admitted to inpatients had significantly poorer PCS only. Perceived social support from a spouse had a statistically significant positive association with PCS and MCS, while perceived social support from family and friends had a statistically significant positive association with MCS only. Also, severity and hindrance of symptoms significantly correlated with PCS and MCS. Using stepwise multiple linear regression analysis, two models were developed to identify factors associated with PCS (Model 1) and MCS (Model 2) health. Model 1 could significantly explain 19% of the variation in PCS (R2 = 0.190, R2adj = 0.180, p = 0.0005), and four factors (symptoms severity, disease stage, comorbidities and employment status) were significantly (p ≤ 0.02) associated with PCS. Model 2 could significantly explain 31.7% of the variation in MCS (R2 = 0.317, R2adj = 0.308, p = 0.0005), and four factors (symptoms severity, employment status, perceived spouse support and perceived family support) were associated (p ≤ 0.04) with MCS. The key findings of this study were that severity of symptoms and social support from spouse and family were associated with HRQOL. Where patients with high symptoms severity were likely to report poor PCS and MCS; and patients with low perceived social support were likely to report poor MCS. Symptoms severity contributed significantly in explaining 28.7% of the variation in PCS and 43.6% of the variation in MCS. Findings for second aim: This study found that the majority of patients had one or more of a wide range of symptoms and social problems. Two-thirds of patients reported joint pain (78.3%), decreased appetite (75.6%) and memory problems (77.3%). Joint pain and depression were reported to have the biggest impact on daily life. Symptoms severity and distress were significantly higher among patients who were: female, illiterate, unemployed, and who had advanced cirrhosis with more complications and comorbidities (p ≤ 0.006). Symptoms severity (r=-0.206) and symptoms distress (r=-0.205) were negatively associated with perceived social support (p=0.005). Stepwise regression analysis showed that the regression model could significantly explain 19.6% of the variation in symptoms severity (R2 = 0.196, R2adj = 0.180, p = 0.0005), and 14% of the variation in hindrance of symptoms (R2 = 0.140, R2adj = 0.132, p = 0.0005). Being female, having an increasing number of liver disease complications, and having low perceived support from spouse were significantly associated with high-perceived symptoms severity and hindrance (p≤0.01). Findings for third aim: This study found that social support score was relatively high among patients with cirrhosis in Egypt (total score mean of MSPSS was 2.02± standard deviation (0.537), while perceived support from spouse was the highest source of support. 67.5% of the patients felt their spouse is around when they need him/her and 71.7% of them share their joys and sorrows with their spouse. Likewise, 64.9% of married people feel their spouse cares about their feelings. In relation to the perception of adequacy of family support, it was observed that 52.6% felt that their families do not really try to help them. At the same time, 52.1% reported that they got the emotional help and support that they needed from their families. Regarding perceived support from friends, more than half of the patients reported that their friends do not really try to help them (57.9%), they cannot count on their friends when things go wrong (65.6%) and they cannot talk about their problems with their friends (56.4%). There was a significantly positive association between the perception of social support and general health perception (GHP), suggesting that when social support decreases GHP also decreases or and vice versa (r= 0.208, p = 0.0005). Stepwise regression analysis showed that the regression model could significantly explain 10.9% of the variation in perceived social support (R2 = 0.109, R2adj = 0.100, p = 0.0005). Marital status, gender, age and employment status were significantly associated with general perceived social support (p ≤ 0.01), while unmarried, females, unemployed and elderly cirrhotic patients were vulnerable groups that were likely to perceive low social support. Overall discussion and conclusion: This is the first study to investigate HRQOL, symptoms experience and perceived social support in patients with liver cirrhosis in Egypt. All aspects of HRQOL of Egyptian cirrhotic patients were poor, and they were experiencing various symptoms that can affect their daily life. However, social support was found to be related to perceived symptoms severity and perceived poor mental health. Hence, social support may alleviate suffering for certain cirrhotic patients. Nurses have a responsibility to assess and treat symptoms that cirrhotic patients experience, particularly such treatable symptoms as depression, pain and decreased appetite. Also, nurses should involve the patient’s family in any plan of care. Future intervention studies that aim to develop programs to relieve treatable symptoms and enhance social support are also recommended.
