Smoking Habits in Bipolar and Schizophrenic Outpatients in Southern Israel

Smoking, nicotine and neuropsychiatric disorders

“…Findings on the smoking rate of bipolar patients in other parts of the world are similar to the US samples. For example, in a Spanish sample, Gonzalez-Pinto et al (1998) also found a higher life-time and point prevalence of smoking among patients with bipolar disorder compared to the control population, while Itkin et al (2001) reported that the current smoking rate was 43% in a patient population with bipolar disorder from southern Israel, which was higher than the current smoking rate of control population (27.5%) and it was comparable to the smoking rate of patients with schizophrenia (45%). A study from Turkey also found higher smoking rates in bipolar patients (55.1%) than in the control population (47.3%) (although the difference was not statistically significant, perhaps because of the relatively small sample size and/or the high smoking rate in the general population).…”

A Hungarian study also reported significantly higher rates of current and ever smoking among bipolar patients compared to the general population (Gonzalez-Pinto et al, 1998;Itkin et al, 2001;Uçok et al, 2004;Dome et al, 2005).…”

Short-Term Naturalistic Treatment Outcomes in Cigarette Smokers With Substance Abuse and/or Mental Illness

“…Prevalence rates for tobacco use in clinical samples in schizophrenics approach 90%, [21][22][23] 43% to 82% in bipolar patients, 2,3,22,24,25 and 45%-60% 2,26 in patients with PTSD. Patients with a history of depression are at increased risk for nicotine dependence (about 50%) 2,3,27 and it is reported that a history of regular smoking occurs more frequently among individuals who have experienced a major depressive episode at some time in their lives.…”

Prevalência de tabagismo em uma unidade de internação psiquiátrica de Porto Alegre

“…Segundo estimativas do Instituto Nacional do Câncer (INCA), no Brasil ocorrem 200.000 mortes/ano associadas ao tabagismo, o que significa que 23 pessoas morrem a cada hora. 3 Vários estudos têm demonstrado a comorbidade entre doenças psiquiátricas graves (como esquizofrenia e transtornos do humor) e dependência de nicotina [4][5][6][7] , sendo que alguns autores sugerem que pacientes psiquiátricos apresentam dependência mais intensa que fumantes sem comorbidade 6 . Entretanto, muitas vezes este diagnóstico não é realizado nos pacientes de unidades psiquiátricas 7 , e os sintomas de abstinência de nicotina (ansiedade, irritabilidade, humor deprimido, insônia) podem ser confundidos com os sintomas que levaram à internação.…”

“…9 Existe uma proporção significativa de dependentes graves em relação aos fumantes em menor grau. Tais achados vão ao encontro de dados descritos por outros autores em amostras semelhantes [4][5][6] . Ressalta-se que não houve diferença significativa entre as três amostras, sugerindo que os achados acima descritos apresentam constância na unidade de internação psiquiátrica estudada.…”
