%X OBJECTIVE: To investigate the associations between television viewing and abdominal obesity (AO) in Brazilian women, according to smoking status. METHODS: Data of 13,262 adult women (18-49 years) from the 2006's Demographic Health Survey, a cross-sectional household study with complex probabilistic sample and national representativeness, were analyzed. AO, defined as waist circumference ≡ 80.0 cm, was the outcome. Television viewing frequency (≡ 5 times/week, 1-4 times/week, < 1 time/week) was the main exposure variable, and smoking status (yes or no) the main co-variable. Prevalence ratios were estimated using Poisson regression models separately for smokers and non-smokers. RESULTS: A statistically significant interaction term was observed between smoking status and television viewing (p < 0.05). Prevalence of AO among smokers who reported television viewing ≡ 5 times/week amounted to 59.0%, higher than the 35.0% for those with < 1 time/week television viewing (p-value = 0.020). The values for non-smokers were 55.2% and 55.7%, respectively. Smokers with television viewing ≡ 5 times/week were 1.7 times (95% CI: 1.1 - 2.5) more likely to pre-sent AO, compared to those who reported a frequency < 1 time/week. There was no significant association among non-smokers. CONCLUSIONS: Television viewing ≡ 5 times/week may increase the prevalence of AO among women who smoke. More detailed information on media use, as hours per day, may offer better estimates. OBJETIVO: Investigar a associa  o entre a frequ那ncia assistindo televis o e obesidade abdominal (OA) entre mulheres brasileiras, segundo o h芍bito de fumar. M谷TODOS: Foram analisados os dados de 13.262 mulheres adultas (18-49 anos) estudadas na Pesquisa Nacional de Demografia e Sa迆de (PNDS-2006), um estudo transversal, com amostragem probabil赤stica complexa, de representatividade nacional. OA, definida como circunfer那ncia da cintura ≡ 80.0 cm, foi considerada como desfecho. A frequ那ncia assistindo televis o (≡ 5 vezes/semana, 1-4 vezes/semana, < 1 vez/semana) foi a principal vari芍vel de exposi  o e o h芍bito de fumar (sim ou n o) a principal covari芍vel. Foram estimadas raz es de preval那ncia por meio de modelos de regress o de Poisson, para fumantes e n o fumantes separadamente. RESULTADOS: Observou-se intera  o estatisticamente significante entre frequ那ncia assistindo televis o e h芍bito de fumar (p < 0,05). A preval那ncia de OA entre mulheres fumantes que assistiam televis o ≡ 5 vezes/semana foi de 59,0%, e maior do que 35,0% entre aquelas que assistiam televis o < 1 vez/semana (p-valor = 0,02).
