- Objective:To investigate the prevalence and the secular trends of obesity in a rural Swedish community with emphasis on the association with socioeconomic status and lifestyle.Design:The Skaraborg Project cross-sectional population surveys were conducted in Vara, a rural community in the southwest of Sweden, every fifth year between 1977 and 2002.Subjects:A total of 3365 residents (1634 men and 1731 women) aged 30-60 years.Measurements:Obesity was defined as body mass index>/=30 kg m(-2). Information on ethnicity, marital status, socioeconomic status and lifestyle was collected by a questionnaire.Results:In 1977-1982, the average prevalence of obesity was 14% in both men and women, and in 2002, the prevalence of obesity was 19% in men and 21% in women. The age-adjusted odds ratio (OR) of obesity in 2002 was 1.48 (1.00, 2.20) in men and 1.41 (0.97, 2.05) in women. Without the simultaneous increase in the level of education and leisure-time physical activity (LTPA), the risk of developing obesity could have been considerably higher; in men OR=3.08 (1.88, 5.03) and in women OR=2.72 (1.66, 4.44). In multivariate models, higher levels of education and LTPA were associated with protective effects on obesity in both men (OR=0.60 (0.43, 0.83) and OR=0.50 (0.45, 0.79)) and women (OR=0.73 (0.54, 0.98) and OR=0.57 (0.42, 0.78)), respectively.Conclusions:This study revealed an upward secular trend in the prevalence of obesity in a rural community in Sweden. Increasing levels of education and LTPA limit this ongoing development of obesity. Public health strategies for the prevention of obesity should consider the special condition in rural environments.International Journal of Obesity advance online publication, 22 January 2008; doi:10.1038/sj.ijo.0803725.

- OBJECTIVE: To validate self-reported information on weight and height in an adult population and to find a useful algorithm to assess the prevalence of obesity based on self-reported information. RESEARCH METHODS AND PROCEDURES: This was a cross-sectional survey consisting of 1703 participants (860 men and 843 women, 30 to 75 years old) conducted in the community of Vara, Sweden, from 2001 to 2003. Self-reported weight, height, and corresponding BMI were compared with measured data. Obesity was defined as measured BMI > or = 30 kg/m2. Information on education, self-rated health, smoking habits, and physical activity during leisure time was collected by a self-administered questionnaire. RESULTS: Mean differences between measured and self-reported weight were 1.6 kg (95% confidence interval, 1.4; 1.8) in men and 1.8 kg (1.6; 2.0) in women (measured higher), whereas corresponding differences in height were -0.3 cm (-0.5; -0.2) in men and -0.4 cm (-0.5; -0.2) in women (measured lower). Age and body size were important factors for misreporting height, weight, and BMI in both men and women. Obesity (measured) was found in 156 men (19%) and 184 women (25%) and with self-reported data in 114 men (14%) and 153 women (20%). For self-reported data, the sensitivity of obesity was 70% in men and 82% in women, and when adjusted for corrected self-reported data and age, it increased to 81% and 90%, whereas the specificity decreased from 99% in both sexes to 97% in men and 98% in women. DISCUSSION: The prevalence of obesity based on self-reported BMI can be estimated more accurately when using an algorithm adjusted for variables that are predictive for misreporting.

- Aims: To explore the association between tooth loss and obesity in an adult Swedish population, and to investigate the influence of socioeconomy, life-style, and co-morbidity.Methods: A cross-sectional population health survey conducted in 2001-2005 in 2816 randomly selected Swedish men and women (age: 30-74 years; participation rate 76%). Main measures were; tooth loss: < 20 remaining teeth (self-reported), general obesity: BMI[≥]30 kg m-2, abdominal obesity: waist circumference > 88 in women and > 102 cm in men. Adjustments were made for socioeconomy, life-style, and co-morbidity.Results: 420 individuals (21.2%) had < 20 remaining teeth: 30-59 years 6.0%, 60-74 years 53.5%. Mean BMI was similar in men and women (26.9 kg m-2), however, both general and abdominal obesity was still more frequent among women (both p < 0.001). There was a significant interaction between age and tooth loss in the association with both general (p = 0.004) and abdominal obesity (p < 0.011) in men. In participants below 60 years of age, the association between tooth loss and general obesity (OR 2.17 [95% CI 1.51 - 3.12]) and abdominal obesity (2.23 [1.58 - 3.15]), respectively, was statistically significant independent of age and gender, and remained so also when accounting for differences in socioeconomy, life-style, and co-morbidity. There was no similar association in those 60 years or older. The findings in men and women were robust and concordant.Conclusions: Common mechanisms for oral health and obesity should be explored more also including longitudinal designs. The findings are important for targeting comprehensive interventions against obesity and tooth loss, especially among younger adults.
