The 2002 Swiss Health Survey is the third survey conducted by the Federal Office of Statistics in intervals of five years. Data are collected of a random sample (n = 19706) of persons aged 15 and over, living in Switzerland: 29% are overweight (BMI 25-29.9 kg/m2), and 8% are obese (BMI 30+ kg/m2). 31% do not care about their nutrition. Less than daily consumption is reported by 34% for fruit, by 18% for vegetable, by 64% for milk, by 39% for milk products. 20% eat every day meat or meat products, 38% do rarely or never consume fish. Inadequate nutritional habits are observed more often in men, young people, and in participants with a low level of education. According to the Swiss Health Surveys of 1992, 1997, and 2002 nutritional habits have hardly improved during the last ten years in Switzerland.
