Dietary habits for non-smoking females living with smokers or non smokers

Background: To investigate whether dietary habits among non-smoking females were different between those living with smokers and non-smokers in two co untries. Methods: A questionnaire was sent to 5,000 females in Sweden and S witzerland. After selection regarding smoking habits, a questionnaire on li fe style factors and diet was distributed. Results: Females living with smo kers showed strong tendencies to be overrepresented among those with less f requent consumption of vegetables, fruit and fibre-rich food and in Switzer land among those with a more frequent consumption of alcohol. Conclusions: The results suggest that non-smoking females living with smokers or non-smo kers differ in their dietary habits. Some smokers' habits represent risk fa ctors for disease and should be controlled for in studies on environmental tobacco smoke.
