AbstractObjectiveThe increasing prevalence of overweight and obesity among children is now an important health problem. This fact, however, does not reflect the scale of the problem. The aim of the present study was to find how much the BMI threshold was exceeded in a population from Kraków.DesignThe study was based on three cross-sectional surveys conducted in 1983, 2000 and 2010. The prevalence of overweight and obesity was estimated based on the International Obesity Task Force cut-off points. In addition to these, an extent of overweight (EOW) index was calculated.SettingPoland.SubjectsChildren aged 3–18 years (n14 534) from Kraków.ResultsBetween the populations examined in 1983 and 2010, the EOW index in boys rose by almost 10 %, and the prevalence of overweight and obesity by 39 %. In girls, however, the EOW index decreased by 45 %, while the prevalence of overweight and obesity remained at similar levels. Analyses in separate age groups showed that the EOW index increased only among early adolescents (150 % for boys, 94 % for girls) and late adolescents (390 % and 64 %, respectively).ConclusionsThe observed increased prevalence of overweight and obesity mainly concerned boys and was accompanied by an increase in the amount by which the BMI threshold values were exceeded.

Introduction: In the diagnosis of overweight and obesity based on body mass index in children and adolescents, several national and international anthropometric references are recommended. However, there is a divergence in the estimated prevalence of overweight and obesity among the references. Objective: To identify the prevalence of overweight and obesity and to analyse the magnitude of agreement among the three references. Methods: A cross-sectional study with 975 students from the early grades of elementary school. The prevalence of overweight and obesity were estimated according to the criteria of the World Health Organization (WHO), the International Obesity Task Force (IOTF) and Conde and Monteiro. The Kappa weighted index was calculated to assess the agreement magnitude among the three references. Results: The highest prevalence of overweight and obesity was estimated by the Conde and Monteiro and WHO references, respectively. Overall, the IOTF revealed lower a magnitude of prevalence than the two other references. The agreement among the references identified by the Kappa index had a range of 0.66 to 0.94. Conclusion: Despite the satisfactory agreement among the three references, this research highlighted the differing magnitudes of the prevalence of overweight and obesity. This fact limits the ability to make comparisons among populations and impairs the development of overweight and obesity prevention actions.

Overweight Or Obesity

Aims: To investigate sex differences in the prevalence and extent of overweight and obesity in adolescents aged 14—18 years. Methods: Standardized measurements of height and weight were collected from surveys of adolescents in the same geographical area in 1966—69 (n = 8378) and in 1995—97 (n = 6673). The prevalence rates of overweight and obesity were calculated using criteria approved by the International Obesity Task Force. The extents of overweight and obesity were assessed by computing age- and sex-specific body mass index (BMI) percentiles. Results: In 1995—97, 17.2% met the criteria for either overweight or obesity, as compared with 10.7% in 1966—69. The prevalence of overweight and obesity combined was higher in girls (13.0%) than in boys (8.5%) in 1966—69 (difference 4.5%, 95% confidence interval (CI) 3.1—5.9), while no sex difference was found in 1995—97 (girls 16.9%, boys 17.5%, difference —0.6, 95% CI —2.3—1.1). The increase in overweight was greater in boys (6.2PP, 95% CI 4.7—7.6) than in girls (1.9PP, 95% CI 0.4—3.5), while the sex difference in increased obesity was smaller (boys 2.8PP, 95% CI 2.1—3.4, girls 2.0PP, 95% CI 1.3—2.6). The increase in extent of overweight and obesity was highest in boys. The values of the 85th percentile and the 95th percentile in boys increased by 1.3 and 3.0 BMI units, respectively. The corresponding increases in girls were 0.7 and 1.7 BMI units. Conclusions: A marked sex difference in time trends for both the prevalence and extent of overweight and obesity, with a more pronounced increase in boys than in girls, was demonstrated. This might have implications for preventive strategies.

Objective. To evaluate change in body mass index (BMI) and weight status of indigenous youth in Oaxaca between the 1970s and 2007. Materials and methods. Heights and weights were measured in cross-sectional samples of school children 6-14 years in the 1970s (2 897) and 2007 (4 305); BMI was calculated. International Obesity Task Force cutoffs for weight status were used. BMI and prevalence of severe and moderate thinness, overweight and obesity were compared by year. Results. BMI increased significantly across time. Primary change in weight status occurred in overweight, 1970s, <2%; 2007, 7 to 12%. Little change occurred in thinness (<2%) and obesity (≤1%) in both surveys, except in children 6-9 years (obesity=4% in 2007). Conclusion. BMI and prevalence of overweight increased across all ages from the 1970s to 2007, but children 6-9 years appeared to be more at risk for obesity than youth 10-14 years. Prevalence of thinness was unchanged.

AbstractObjective:To assess the prevalence of underweight, overweight and obesity in French children from 2013 to 2017.Design:Cross-sectional study performed in fourteen regions of France. Physical measures included weight, height and BMI. Underweight, overweight and obesity were defined according to age- and sex-specific BMI cut-off points from the International Obesity Task Force.Setting:France.Subjects:Children (10 159 boys, 9757 girls) from the voluntary, non-representative Diagnoform programme between 2013 and 2017, at the age of 4–12 years.Results:The prevalence of overweight and obesity was higher in girls compared with boys (P < 0·001). Underweight was also more prevalent in girls (P < 0·05). Although there were no significant changes in the prevalence of obesity in boys or girls from 2013 to 2017, a significant decrease in overweight among boys and girls was found (P < 0·001) during the same time period. In contrast, the prevalence of underweight increased in girls and boys (from 10·0 to 20·0 %, P < 0·0001) between 2013 and 2017.Conclusions:Results of the current study show that the prevalence of obesity was stable, while the prevalence of overweight decreased significantly, despite high in French children. Findings suggest also that thinness is becoming an important phenomenon in children. Developing preventive and nutritional programmes in order to modify the lifestyle might help control underweight and obesity in children.

AbstractObjectiveTo determine the prevalence of underweight, overweight and obesity in French youth from 2009 to 2013 and to determine if there are differences in weight categories according to socio-economic status.DesignCross-sectional study performed in different regions of France. Physical measures included weight, height and BMI. Underweight, overweight and obesity were defined according to age- and sex-specific BMI cut-off points from the International Obesity Task Force.SettingFrance.SubjectsChildren and adolescents (n 9670; 4836 boys, 4834 girls) from the French national BOUGE Program between 2009 and 2013.ResultsThe prevalence of obesity was higher in boys than girls (P<0·05). In contrast, underweight was more prevalent in girls (P<0·05). Although there were no significant changes in overweight or underweight boys or girls from 2009 to 2013, there was a significant increase in obesity in boys and girls (P<0·05) during the same time period. The prevalence of underweight increased in girls from 12·0 to 16·7 % (P >0·05) and remained unchanged in boys (7·1–7·3 %) between 2009 and 2013. Overweight and obesity were higher in low socio-economic families (P<0·0001).ConclusionsFindings suggest that the prevalence of overweight was stable although high in French children and adolescents, while the prevalence of obesity increased significantly. Changes in underweight, although not significant, were high in girls and merit further attention. Improving public health interventions, especially in high-risk low socio-economic populations, may help to modify the behaviour that contributes to underweight, overweight and obesity in young boys and girls.

Abstract.Aim: To assess the association of breakfast skipping with overweight and obesity among children in Albania, a post-communist country in the Western Balkans, which is undergoing a long and difficult political and socioeconomic transition towards a market-oriented economy. Methods: A nationwide cross-sectional study was carried out in Albania in 2013 including a representative sample of 5810 children aged 7.0 – 9.9 years (49.5% girls aged 8.4 ± 0.6 years and 51.5% boys aged 8.5 ± 0.6 years; overall response rate: 97%). Children were measured for height and weight, and body mass index (BMI) calculated. Cut-off BMI values of the World Health Organization (WHO) and the International Obesity Task Force (IOTF) were used to define overweight and obesity in children. Demographic data were also collected. Results: Upon adjustment for age, sex, and place of residence, breakfast skipping was positively related to obesity (WHO criteria: OR = 1.5, 95% CI = 1.3–1.9; IOTF criteria: OR = 1.9, 95% CI = 1.4–2.5), but not overweight (OR = 1.1, 95% CI = 0.9–1.3 and OR = 1.1, 95% CI = 0.9–1.4, respectively). Furthermore, breakfast skipping was associated with a higher BMI (multivariable-adjusted OR = 1.05, 95% CI = 1.02–1.07). Conclusions: Our findings point to a strong and consistent positive relationship between breakfast skipping and obesity, but not overweight, among children in this transitional southeastern European population. Future studies in Albania and other transitional settings should prospectively examine the causal role of breakfast skipping in the development of overweight and obesity.

Abstract Background Evidence was previously provided for sex-related differences in the human gut microbiota composition, and sex-specific discrepancy in hormonal profiles was proposed as a main determinant of these differences. On the basis of these findings, the assumption was made on the role of microbiota in the sexual dimorphism of human diseases. To date, sex differences in fecal microbiota were demonstrated primarily at lower taxonomic levels, whereas phylum-level differences between sexes were reported in few studies only. In the present population-based cross-sectional research, sex differences in the phylum-level human gut microbiota composition were identified in a large (total n = 2301) sample of relatively healthy individuals from Ukraine. Results Relative abundances of Firmicutes and Actinobacteria, as determined by qRT-PCR, were found to be significantly increased, while that of Bacteroidetes was significantly decreased in females compared to males. The Firmicutes to Bacteroidetes (F/B) ratio was significantly increased in females compared to males. Females had 31 % higher odds of having F/B ratio more than 1 than males. This trend was evident in all age groups. The difference between sexes was even more pronounced in the elder individuals (50+): in this age group, female participants had 56 % higher odds of having F/B ratio > 1 than the male ones. Conclusions In conclusion, sex-specific differences in the phylum-level intestinal microbiota composition were observed in the Ukraine population. The F/B ratio was significantly increased in females compared to males. Further investigation is needed to draw strong conclusions regarding the mechanistic basis for sex-specific differences in the gut microbiota composition and regarding the role of these differences in the initiation and progression of human chronic diseases.

OBJECTIVE: To assess the prevalence of low body weight/thinness, overweight and obesity in a representative sample of children and adolescents from a Brazilian region with low economic development. METHODS: A total of 982 girls and 986 boys, aged seven to 17 years old and assisted by Segundo Tempo Program, from Montes Claros, Minas Gerais, Brazil, were included in the study. Low body weight/thinness, overweight and obesity were defined based on body mass cut-off indexes recommended by the International Obesity Task Force. The prevalence of the nutritional status according to sex and age was compared by chi-square test. RESULTS: In girls, the frequency of low body weight/thinness, overweight and obesity was 4.1, 18.4 and 3.8%, respectively; in boys, these percentages were 6.3, 13.2 and 2.9%, respectively. The low body weight/thinness for girls raised from 2.7% (7-10 years old) to 5.5% (15-17 years old); the body weight excess (overweight and obesity) decreased from 30.1 to 16.2% for the same age groups. In boys, the corresponding trends were from 3.2 to 9.4% for low body weight/thinness, and from 23.4 to 9.2%, for body weight excess. CONCLUSIONS: The data indicate that, even in a region with low economic status, the body weight excess was the main problem associated with nutritional health. The high overweight and obesity prevalence rates indicate the need of public policies for promoting healthy feeding behaviors and physical activity.

Abstract Background The extent of the obesity epidemic among youth is an important public health statistic which provides an indication of the future burden of non-communicable diseases. Many developing countries, including Albania, do not have systematic and repeated monitoring systems in operation. Methods The Balkan Survey of Inactivity in Children study is a population-based cross-sectional survey including Albanian children living in the four Balkan nation-states of Albania, Kosovo, FYR Macedonia and Montenegro. In total, 19,850 children from 49 schools were approached. The LMS method was used to provide body mass index (BMI), height, weight and waist circumference reference centiles for boys and girls. The World Health Organisation (WHO) and International Obesity Task Force (IOTF) age- and sex-specific BMI cut-points were applied to evaluate adiposity levels. Results A sample of 18,460 participants aged 6–16 years old was available for creation of the BMI for age and sex reference centiles. The prevalence of overweight (including obesity) in the full sample was 21% (95% CI: 20%–21%) according to IOTF cut-off points and 28% (95% CI: 28%–29%) at WHO cut-off points. Overweight/obesity levels where higher in boys than in girls irrespective of the cut-off points applied (p<0.001). Noticeable between-country differences were observed with a prevalence of overweight/obesity of 40% (95% CI: 38%–42%) in Montenegro but only 20% (95% CI: 19%–21%) in Kosovo (WHO cut-off points). Conclusions Overweight/obesity is highly prevalent in Albanian children and adolescents. The apparent sex and country differences may inform public health actions.
