DESIGN: Data from the Swedish Surveys of Living Conditions were used. Three such surveys were undertaken in 1980/81, 1988/89, and 1996/97, each of which was based on a simple random sample from the national population registry. SUBJECTS: A total of 38,284 observations are used in this analysis, including males and females aged 16-84. The sample is approximately equally divided among the 3 survey periods and by gender. MEASUREMENTS: The following body weight categories are used to describe changing prevalences: overweight (BMI>/=25), obesity (BMI>/=30) and underweight (BMI<18.5). Because body weight and heights were self-reported, recorded values were adjusted for estimating gender-specific obesity prevalences. Education was used as a proxy for socioeconomic status. RESULTS AND CONCLUSIONS: The prevalence of BMI>/=30 increased significantly over the 16-year observation period. At the time of the 1980/81 survey, the adjusted estimates were 8.8% in women and 6.6% in men, compared to 11.9% and 10.0% respectively, in 1996/97. The prevalence of BMI>/=25 was also analyzed for time trends, with specific attention to populations at risk. The largest proportionate changes occurred in women aged 16-44, among whom the prevalence of overweight doubled. The inverse educational gradient with respect to obesity is still present in both sexes, but there is no indication that it has increased in magnitude between 1980/81-1996/97.

Acquired preference especially for dietary fat and obesity: a study of weight-discordant monozygotic twin pairs

- Department of Psychiatry, University of Helsinki, Finland. OBJECTIVE: To determine the independent associations of dietary preference for fat with obesity without the confounding by genetic effects. DESIGN: Descriptive comparison of the responses of monozygotic twins discordant for obesity to questions concerning current and past preference for dietary fat, current overconsumption of fatty items and recalled food consumption compared to the co-twin. SETTING: The Research and Development Centre of the Social Insurance Institution, Finland. SUBJECTS: Twenty-three healthy monozygotic twin pairs who were discordant for obesity (BMI difference at least 3 kg/m(2)). MAIN OUTCOME MEASURES: Obesity status of the twin, as a function of the current and recalled dietary preferences and selected psychosocial variables. RESULTS: The obese twins reported current preference for fatty foods three times more frequently than the lean co-twin. Moreover, when comparing recalled taste for fat at the time the twins left their parental homes, both the obese and lean co-twins consistently recalled that the obese twin had greater preference for fatty foods in young adulthood, and that the lean twin had less. Psychological characteristics of lean and obese co-twins did not differ. CONCLUSION: Acquired preference for fatty foods is associated with obesity, independent of genetic background. Modification of fat preferences may be an important step in the prevention of obesity in the general population. PMID: 12080452 [PubMed - indexed for MEDLINE]
