| Summary: | nÃo hà === A doenÃa renal crÃnica (DRC) dialÃtica se associa a vÃrios estressores que afetam negativamente a dinÃmica das relaÃÃes sociais.O apoio social recebido pelas pessoas com DRC dialÃtica influencia diretamente a morbimortalidade e a qualidade de vida,assim à importante conhecer as possÃveis associaÃÃes entre apoio social ofertado Ãs pessoas com DRC dialÃtica e variÃveis sociodemogrÃficas e clÃnicas. O estudo teve por objetivo verificar a associaÃÃo do apoio social autopercebido com variÃveis sociodemogrÃficas e clÃnicas entre pessoas com DRC submetidas à hemodiÃlise (HD). Foram incluÃdos 161 indivÃduos com DRC submetidos à HD provenientes dos dois Ãnicos centros de diÃlise existentes na regiÃo norte do Estado do CearÃ. Foram excluÃdos os pacientes com idade inferior a 18 anos e tempo em HD menor do que trÃs meses. Foi utilizada a Escala de Apoio Social do Medical Outcomes Study para avaliaÃÃo do apoio social percebido pelos participantes. Esse instrumento abrange cinco dimensÃes de apoio social: Material, Afetivo, Emocional, InformaÃÃo e InteraÃÃo Social Positiva. A pontuaÃÃo gerada pelo instrumento varia de 0 a 100. Os seguintes dados sociodemogrÃficos foram obtidos: gÃnero, idade, religiÃo e estado civil. A classificaÃÃo socioeconÃmica correspondeu ao CritÃrio Brasil da AssociaÃÃo Brasileira de Institutos de Pesquisa de Mercado, que resulta na classificaÃÃo de cinco estratos de classe social de A (melhor nÃvel) a E (pior nÃvel). Os seguintes dados clÃnicos foram obtidos: etiologia da DRC, tempo de manutenÃÃo em HD e grau de comorbidades, de acordo com o Ãndice de Khan. Foram comparadas as pontuaÃÃes referentes a cada dimensÃo do apoio social autopercebido de acordo com as seguintes variÃveis sociodemogrÃficas: sexo; idade; estado civil; religiÃo; e estado socioeconÃmico. Foram comparadas as pontuaÃÃes referentes a cada dimensÃo do apoio social autopercebido de acordo com as seguintes variÃveis clÃnicas: tempo de manutenÃÃo em HD; diabÃticos versus nÃo-diabÃticos; e grau de comorbidade. O teste t de Student foi utilizado para inferir a diferenÃa estatÃstica das comparaÃÃes. O p<0,05 foi estabelecido para indicar significÃncia estatÃstica. A amostra foi formada por maioria de homens (65,3%), com idade mÃdia de 50,3 anos, com maior concentraÃÃo nas classes socioeconÃmicas C e D (91,3%) e com maioria de catÃlicos (79,5%). A principal etiologia da DRC foi hipertensÃo arterial (34,2%) seguida de glomerulonefrite (25,2%) e diabetes mellitus (21,7%). As pessoas estavam em tratamento de HD por 46,2 meses em mÃdia. Mais da metade da amostra (50,9%) apresentava baixo grau de comorbidade. Apoio social do tipo Afetivo foi o melhor pontuado (mÃdia de pontuaÃÃo=87,7) e do tipo InteraÃÃo Social Positiva apresentou a pior pontuaÃÃo (mÃdia de pontuaÃÃo=73,5). As variÃveis sociodemogrÃficas que se associaram com o apoio social foram: idade, estado civil e classe socioeconÃmica, da seguinte forma: idosos apresentaram maior pontuaÃÃo referente à dimensÃo Material (91, 6 versus 80,5; p=0,005); casados perceberam maior apoio social referente Ãs dimensÃes Material e Emocional, respectivamente, 86,7 versus 76,8 (p=0,015) e 86,4 versus 76,0 (p=0,008); e as pessoas das classes socioeconÃmicas B e C pontuaram mais do que das classes D e E no que se refere à dimensÃo do apoio social Afetivo (90,2 versus 81,5; p=0,047). Entre as varÃveis clÃnicas estudadas, a Ãnica variÃvel que se associou com apoio social foi tempo de manutenÃÃo em HD, com menor tempo de hemodiÃlise sendo associado a melhor apoio material (86,8 versus 77,2; p=0,040). As seguintes pessoas em HD devem ser vistas como em risco de receberem menor apoio social: os mais jovens, os solteiros, os de classe socioeconÃmica mais baixa e aqueles mantidos em HD por mais de 36 meses. Propomos as seguintes estratÃgias de intervenÃÃo: medidas educacionais, busca por recursos materiais nas comunidades e fortalecimento da interaÃÃo dos pacientes. === Chronic kidney disease (CKD) requiring dialysis is associated with various stressors that negatively affect the dynamics of social relations. Social support received by people with CKD on dialysis directly influences the mortality and quality of life. In this context it is important to know the possible associations between social support offered to people with CKD on dialysis and sociodemographic and clinical variables. Our study aimed to verify the association of self-perceived social support with sociodemographic and clinical variables among people with CKD undergoing hemodialysis (HD). We included 161 patients with CKD undergoing HD from the only two existing dialysis centers in the north of the State of CearÃ. Patients under the age of 18 years and time on HD less than three months were excluded. We used The Medical Outcomes Study Social Support Survey for evaluation of social support perceived by the participants. This instrument consists of 19 items covering five dimensions of social support: Material (provision of material assistance), Affective (physical displays of affection), Emotional (emotional needs), Information (count on people to inform and guide) and Positive Social Interaction (count with people to relax). The score generated by the instrument ranges from 0 (worst possible social support) to 100 (best possible social support). The following sociodemographic data were obtained: gender, age, religion and marital status. The socioeconomic classification corresponded to the criteria Brazil according to the Brazilian Association of Market Research Institutes, which results in the classification of five social classes: A (highest level) to E (lowest level). The following clinical data were obtained: etiology of CKD, time on maintenance HD and degree of comorbidities, according to Khan Index which ranks three degrees of comorbidity: grade I (low risk), grade II (medium risk) and grade III (high risk). Scores for each dimension of self-perceived social support were compared according to the following sociodemographic variables: men vs. women; elderly (older than or equal to 60 years) vs. non-elderly (age less than 60 years); married vs. not married; catholic vs. non-catholic; socioeconomic classes B + C vs. D + E. Scores for each dimension of self-perceived social support were compared according to the following clinical variables: time on maintenance HD up to 36 months vs. longer than 36 months; diabetics vs. non-diabetics; and low risk of comorbidity vs. medium + high risks. Studentâs t test was used to infer the statistical significance of the comparisons. The p <0.05 was set to indicate statistical significance. The sample was formed by a majority of men (65.3%) with mean age of 50.3 years, with a greater concentration on socioeconomic classes C and D (91.3%) and a majority of catholics (79.5%). The main cause of CKD was hypertension (34.2%) followed by glomerulonephritis (25.2%) and diabetes mellitus (21.7%). People were treated by HD for 46.2 months on average. More than half the sample (50.9%) had low risk due to comorbidity. The Affective dimension of social support was the best scored (mean score=87.7 points) and the Positive Social Interaction was the worst score (mean score=73.5). The sociodemographic variables associated with social support were age, marital status, and socioeconomic status, as follows: elderly had higher scores for the dimension Material (91.6 vs. 80.5; p=0.005); married people perceived greater social support related to the dimensions Material and Emotional, respectively 86.7 versus 76.8 (p=0.015) and 86.4 versus 76.0 (p=0.008); and people from socioeconomic classes B and C scored more than the classes D and E in relation to the dimension Affective of social support (90.2 vs. 81.5; p=0.047). Among the clinical variables studied, the only variable associated with social support was time on HD, as follows: people with less time on HD perceived greater social support related to the dimension Material than people with more time on HD (86.8 vs. 77.2; p=0.040). The following persons in HD should be seen as at risk of receiving less social support: the younger, not married, from lower socioeconomic class and those on HD for more than 36 months. We propose the following strategies focused on people at risk of receiving less social support: educational interventions, search for material resources in the communities where people on HD live and strengthening the interaction of patients with family and friends.
