Weight Status of 7-Year-Old Hungarian Children between 2010 and 2016 Using Different Classifications (COSI Hungary)

Changes in weight status of 7-year-old children in North Macedonia between 2010 and 2019

Childhood obesity is growing as one of the most important public health issues that affects individual and population health but also puts heavy burden on the health systems. It is frequently associated with immediate adverse consequences, such as psychological problems, and a higher risk of many harmful comorbidities later in life, such as type 2 diabetes, dyslipidemia, non-alcoholic fatty liver disease, hypertension, and coronary heart disease. Comparability of anthropometric data is crucial to track the changes over time. The aim of this paper was to present prevalence of thinness, overweight, and obesity in 7-year-old schoolchildren in North Macedonia in 2010 and 2019, and the changes in their nutritional status during thatperiod. Material and methods: Anthropometric measurements of body height and body weight were performed to the nationally representative sample of 7-year-oldchildren in school years 2010/2011 and 2018/2019. Measurements followed the Childhood Obesity Surveillance Initiative (COSI) protocol and data collecting procedures. In total, 2737 children (1317 girls and 1420 boys) in 2010 and 2059 children (1045 girls and 1014 boys) in 2019 were measured. WHO Growth references were used to determine the growth and nutritional status of children. Results: The average height of children in the observed period has increased by 1.7 cm, weight for 1.2 kg and the BMI for 0.3 kg/m2. As for the weight classification, thinness prevalence is significantly increased for 0.3%. Overweight (including obesity) significantly increased (p=0.0377) from 34.4% (95% CI 32.6%-36.2%) in 2010 to 37.3% (95% CI 35.2%-39.5%) in 2019. Obesity significantly increased (p=0.040) from 16.3% (95% CI 14.9%-17.7%) in 2010 to 18.4% (95% CI 16.7%-20.1%) in 2019. The main driver of that increase was the highly significant (p=0.0004) increase of almost 7% of overweight (including obesity) in girls. Conclusion: There is unfavorable rising trend which indicates deterioration of the situation with childhood obesity in the country. Focused and more comprehensive public health nutrition actions are needed to plateau or reverse the trends. The childhood obesity national monitoring system is well established and should continue to beone of the key public health monitoring systems that provide evidence for actions.  

Secular Trends of Underweight, Overweight, and Obesity in Children and Adolescents from Ukraine

Overweight and obesity, as well as underweight in children and adolescents, pose a significant public health issue. This study aimed to investigate the secular trend of the incidence of underweight, overweight, and obesity in children from Ukraine in 2013/2014 and 2018/2019. The studies were conducted in randomly selected primary and secondary schools in Ukraine. In total, 13,447 children (6468 boys and 6979 girls) participated in the study in 2013/2014 and 18,144 children (8717 boys and 9427 girls) participated in 2018/2019. Measurements of body weight and height were performed in triplicate. Underweight, overweight, and obesity were diagnosed according to the standards of the World Health Organization (WHO). In the group of girls, a significant difference between 2013/2014 and 2018/2019 measurements was found only among 7-year-olds. The percentage of girls at this age exceeding the body mass index (BMI) norm was lower in the 2018/2019 study. In boys, a significant difference was also found in 7-year-olds, and, as in girls, a lower share of overweight and obesity was found in 2018/2019. But for the ages of 12, 13, and 15, the significant differences had a different character-more overweight or obese boys were found in the 2018/2019 study. The proportion of underweight children was similar for the majority of age groups in both genders and did not differ in a statistically significant way.

Reversal of the Upward Trend of Obesity in Boys, but Not in Girls, in Spain

(1) Background: To compare the prevalence of overweight and obesity in boys and girls and to estimate socioeconomic differences associated with obesity in Spain in 1997, 2007, and 2017. (2) Methods: Data were drawn from national health interview surveys. For each year of study, the prevalence of overweight and obesity was measured, and these results were compared by gender (boy/girl) and socioeconomic status (low/high education). (3) Results: The prevalence of overweight and obesity rose from 1997 to 2007 but then fell in 2017 in all subgroups except in girls aged 10 to 15 years. In this group, there was a steady increase in the prevalence of both overweight (1997, 14.6%; 2007, 17.7%; 2017, 19.6%) and obesity (1.1, 3.2, and 3.7%, respectively). The decrease in prevalence of overweight in both sexes and of obesity in boys, along with the increase in prevalence of obesity in girls, was of a higher magnitude in children whose parents had a lower educational level. (4) Conclusions: The apparent turnaround in the obesity epidemic in Spain should be interpreted with caution. Children’s body weight is influenced by both gender and socioeconomic status—considerations that should be kept in mind when designing health promotion interventions.

Changes in the incidence and prevalence of type 1 and type 2 diabetes among 2 million children and adolescents in Hungary between 2001 and 2016 - a nationwide population-based study

INTRODUCTION

The aim of the present study was to assess changes in the incidence and prevalence of type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in children and adolescents in Hungary during the period 2001 to 2016 in order to provide nationwide population-based epidemiology data on diabetes in youths aged 0-18 years.

MATERIAL AND METHODS

This was a retrospective cohort study of Hungarian children and adolescents aged 18 years or younger. Pharmacologically treated diabetes cases were obtained through a population-based registry of the Hungarian National Health Insurance Fund. Time series analysis was used to evaluate the changing patterns of the incidence and prevalence for type 1 and type 2 diabetes covering a 16-year period.

RESULTS

During the study period, 6,138 and 1,997 new T1DM and T2DM cases were observed, respectively. Newly diagnosed T2DM cases accounted for 24.5% of all incident diabetes cases. Incidence of T1DM increased from 16/100,000 to 23/100,000 (R ² = 0.7681; p < 0.0001). The male-to-female ratio among newly diagnosed T1DM patients did not change over the study period. Prevalence of T1DM rose from 114/100,000 to 209/100,000 (R ² = 0.9909; p < 0.0001). The prevalent T1DM cases showed significant male predominance in every year (p < 0.05). Incidence of T2DM decreased from 8/100,000 to 5/100,000 (R ² = 0.4977; p < 0.0014). The overall prevalence of T2DM did not change significantly. Prevalent T2DM cases showed significant female predominance in every year (p < 0.0001). A significant decrease in male-to female ratio was observed among newly diagnosed T2DM cases over the study period (p < 0.0001).

CONCLUSIONS

According to these population-based Hungarian data of children and adolescents with diabetes, T1DM is still the most common form and its frequency continues to rise, affecting more males than females. A high proportion of patients have T2DM, affecting more females than males, but the occurrence of medically treated cases is not increasing. The decrease in male-to-female ratio in newly diagnosed T2DM cases needs further investigations.

Substantial variation across geographic regions in the obesity prevalence among 6-8 years old Hungarian children (COSI Hungary 2016)

Background

There have been previous representative nutritional status surveys conducted in Hungary, but this is the first one that examines overweight and obesity prevalence according to the level of urbanization and in different geographic regions among 6–8-year-old children. We also assessed whether these variations were different by sex.

Methods

This survey was part of the fourth data collection round of World Health Organization (WHO) Childhood Obesity Surveillance Initiative which took place during the academic year 2016/2017. The representative sample was determined by two-stage cluster sampling. A total of 5332 children (48.4% boys; age 7.54 ± 0.64 years) were measured from all seven geographic regions including urban (at least 500 inhabitants per square kilometer; n = 1598), semi-urban (100 to 500 inhabitants per square kilometer; n = 1932) and rural (less than 100 inhabitants per square kilometer; n = 1802) areas.

Results

Using the WHO reference, prevalence of overweight and obesity within the whole sample were 14.2, and 12.7%, respectively. According to the International Obesity Task Force (IOTF) reference, rates were 12.6 and 8.6%. Northern Hungary and Southern Transdanubia were the regions with the highest obesity prevalence of 11.0 and 12.0%, while Central Hungary was the one with the lowest obesity rate (6.1%). The prevalence of overweight and obesity tended to be higher in rural areas (13.0 and 9.8%) than in urban areas (11.9 and 7.0%). Concerning differences in sex, girls had higher obesity risk in rural areas (OR = 2.0) but boys did not. Odds ratios were 2.0–3.4 in different regions for obesity compared to Central Hungary, but only among boys.

Conclusions

Overweight and obesity are emerging problems in Hungary. Remarkable differences were observed in the prevalence of obesity by geographic regions. These variations can only be partly explained by geographic characteristics.
