“…Higher social status (highly qualified occupation of father vs manual worker) is a protective factor for overweight in Jena children (Kromeyer-Hauschild et al, 1999). This inverse relationship between social status and overweight was found frequently (De Spiegelaere et al, 1998;Sakamoto et al, 2001;Langnaese et al, 2002) and may be the main explanation for the low prevalence estimates in children from Jena.…”

Objective: Data of Jena children (Germany) show increases in the prevalence estimates of overweight and obesity between 1975 and 2001. Our objective was to determine if these increases contribute to changes in the distribution of body mass index (BMI) in the entire population of children. The decade 1985-1995, which includes the time of German reunification, is of particular interest because of the significant socio-economic changes in East Germany, in which Jena is located. Design and subjects: The analyses were based on data from four cross-sectional growth studies in 7-to 14-year-old children performed in Jena, Germany, in 1975 (n ¼ 2013), 1985 (n ¼ 1534), 1995 (n ¼ 1906 (n ¼ 1918. Overweight and obesity were estimated by German reference data and the reference of Cole et al. Mean difference plots were used to investigate the changes in the BMI distributions within sexes between the studies. Results: Between 1985 and 1995, the prevalence of overweight and obesity increased significantly in both sexes, whereas nonsignificant changes were found between 1975 and 1985. Although there is a tendency towards increased overweight between 1995 and 2001, the differences were nonsignificant. Comparing data from 1975 and 1985, the mean difference plots showed virtually no changes in the BMI distribution. In the plots comparing the BMI distribution for 1985 data and 1995 data, the whole distribution tended to shift upwards with a greater shift in the upper BMI range. The entire population of children in Jena gained weight during this period of time. This increase may be linked to a transition towards a more Western lifestyle, that is, usually by lower energy expenditure and nutritional transitions, caused by the process of reunification of Germany in 1989. Conclusions: Weight gain appears to be a characteristic feature of the entire population studied and does not seem to be a separate problem of the obese children. This suggests that reported changes in the prevalence may be underestimating the looming public health crisis.

Change in body mass index from adolescence to young adulthood and increased carotid intima-media thickness at 28 years of age: The Atherosclerosis Risk in Young Adults study

Obesity has become a major health problem in Western societies by increasing the risk of atherosclerosis and cardiovascular disease. Although data on tracking of body mass index (BMI) are available, little is known about the impact of weight change over time on the development of vascular damage. OBJECTIVE: To evaluate the relationship between adolescent BMI as well as change in BMI from adolescence into young adulthood and cardiovascular risk, as estimated by common carotid intima-media thickness (CIMT). DESIGN: Cohort study. SUBJECTS: A total of 750 healthy young adults, aged 27-30 y, who attended secondary school in Utrecht, the Netherlands. MEASUREMENTS: Data on adolescent weight, height, blood pressure and puberty stage were available from the original school health records of the Municipal Health Service. At young adulthood, a questionnaire on cardiovascular risk factors was completed and fasting blood sample was drawn and common CIMT was measured. RESULTS: One standard deviation (s.d.) increase in adolescent BMI was associated with 2.3 mm [95% confidence interval (CI): 1.3; 3.3] increase in mean common CIMT in young adults after adjustment for gender, adolescent age, adolescent blood pressure, puberty stage and lumen diameter. Further adjustment for adult cardiovascular risk factors did not change the relationship (linear regression coefficient ¼ 2.1 mm/s.d.; 95% CI: 1.0; 3.1). Adjustment for adult BMI attenuated the association (linear regression coefficient ¼ 0.9 mm/s.d.; 95% CI: À0.3; 2.2) as the majority of overweight and obese adolescents remained overweight or became obese young adults. Subjects who remained in the upper BMI distribution from adolescence into young adulthood had a significantly higher common CIMT compared to those who showed relative weight loss over time (mean difference 14.7 mm; Po0.001). These latter showed similar CIMT values as individuals with constant low BMI. CONCLUSION: Adolescent BMI predicts cardiovascular risk, as estimated by common CIMT in young adulthood. Individuals who experience the largest increase in BMI and those who remain overweight over time have the thickest common CIMT.

“…28 -33 The prevalence of obesity among school children aged 6 -12 y in Thailand (diagnosed by weight-forheight > 120% of the Bangkok reference), rose from 12.2% in 1991 to 15.6% in 1993. 29 Ding 32 also reported that the prevalence of obesity among children of 0 -7 y in China increased from 0.91% in 1986 to 2.0% in 1996. These estimates were much lower than our findings, partly because different obesity standards and populations were used.…”
