“…The prevalence of overweight and obesity is increasing in adults as well as in children worldwide (Livingstone, 2000;Bundred et al, 2001;Magarey et al, 2001;Kain et al, 2002;Dietz, 2004). Epidemiological data show that obesity and overweight are multi-determined chronic health problems resulting from complex interactions between genes and an environment that promotes high-energy intake and lowenergy expenditure, resulting in a positive energy balance (Gunnell et al, 1998;Weinsier et al, 1998;Goran, 2001).…”

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.

“…The IOTF reference produced a lower prevalence of overweight than the CDC reference in the younger children 2-14 years. Additionally, in a large sample of Chilean children aged 6 years, it was reported that the overall prevalence of obesity was halved when using the IOTF reference compared to the CDC reference (Kain et al, 2002).…”

Prevalence of overweight and obesity in Irish school children, using four different definitions

Objective: To determine the prevalence of overweight and obesity in Irish children using four different weight-for-height methods and to examine secular trends from previous national data. Design: A cross-sectional survey. Weight and height were measured according to standard procedures and used to determine the prevalence of overweight and obesity using four weight-for-height methods of assessment, actual relative weight, the Centers for Disease Control and Prevention body mass index (BMI) for age charts for boys and girls, the BMI reference curves for the UK 1990 and the International Obesity Task Force age-and sex-specific BMI cutoffs. Results: The prevalence of overweight and obesity in Irish children is high, but varies considerably with each method. The prevalence of obesity in boys ranged from 4.1 to 11.2 % and in girls from 9.3 to 16.3%. Between 1990 and 2005, depending on the method used, there was a two-to-fourfold increase in obesity in children aged 8-12 years. Conclusion: It is evident given the variation displayed in the prevalence of obesity when using the different methods, that there is a discernible need for a single definition to identify the obese child in Ireland. The findings show a high prevalence of overweight and obesity in Irish school children and the increase in the prevalence of obesity over the last 15 years highlights this growing public health issue.

“…It prepared BMI percentiles from databases of six countries with low prevalence of overweight and obtained the percentile corresponding to a BMI of 25 kg/m 2 for different age groups and both genders. In general, compared to other references, WHO's standards produce similar estimates of overweight but lower estimates of obesity (Reilly et al, 2000;Kain et al, 2002;Abrantes et al, 2003). Chilean investigators have developed local percentiles of BMI for age and have proposed the use of percentiles based not on age but on Tanner stage (Burrows and Muzzo, 1999;Burrows, 2001).…”

Objective: To elaborate Mexican growth charts based on international methodology. Design: Data were obtained from the Mexican National Health Survey. The survey was stratified and probabilistic representative of all the country.Setting: Nationwide open population living in urban and rural areas. Subjects: Boys (8545) and girls (9983) from 10 to 18 years participating in the survey. Methods: Age, weight and height were recorded. Empirical percentiles were calculated and smoothed. Smoothed curves were approximated using least-mean square estimation. Results : Tables and figures for percentile values of weight, height and body mass index (BMI) for age, as well as percentile values of weight and BMI for height for both genders are presented. Regarding 50th BMI for age percentiles, Mexicans had higher levels than the Americans in the Centers for Disease Control and Prevention growth charts; Mexicans were lower but had similar weights than the Americans. Owing to the high BMI, the percentile corresponding to an overweight level (25 kg/m 2 ) at 18 years was 74.5 in boys and 72.5 in girls, whereas obesity level (30 kg/m 2 ) at 18 years was 97.3 and 97.4 in boys and girls, respectively. Conclusions: The present growth charts are snapshots of a Mexican population. Because the high median BMI compared to US and World Health Organization standards, we must be cautious in establishing an upper normal cutoff for clinical normality, not merely selecting the 85th and 95th percentiles as equivalents of overweight and obesity, respectively. Therefore, we proposed percentiles 74.5 in boys and 72.5 in girls as the action points of overweight as they are the percentiles corresponding to BMI 25 kg/m 2 at 18 years.
