Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases developing in childhood. The incidence of the disease in children increases for unknown reasons at a rate from 3 to 5% every year worldwide. The background of T1DM is associated with the autoimmune process of pancreatic beta cell destruction, which leads to absolute insulin deficiency and organ damage. Complex interactions between environmental and genetic factors contribute to the development of T1DM in genetically predisposed patients. The T1DM-inducing autoimmune process can also affect other organs, resulting in development of additional autoimmune diseases in the patient, thereby impeding diabetes control. The most common T1DM comorbidities include autoimmune thyroid diseases, celiac disease, and autoimmune gastritis; additionally, diabetes can be a component of PAS (Polyglandular Autoimmune Syndrome). The aim of this review is to assess the prevalence of T1DM-associated autoimmune diseases in children and adolescents and their impact on the course of T1DM. We also present suggestions concerning screening tests.

Vitamin D may prevent dental caries. To date, no attempts have been made to examine the correlation between the incidence of caries and the concentrations of vitamin D in children with pituitary growth hormone deficiency.The study observed patients of the Department of Endocrinology and Diabetology of the University Paediatric Hospital of the Medical University of Lublin treated with human recombinant growth hormone for pituitary growth hormone deficiency (GHD). The study was conducted between October 2014 and June 2015. The study group consisted of 121 children and adolescents (6–17 years old), including 56 children from rural areas and 65 children from urban areas. The study group was stratified by area of residence.In our study, the increase in vitamin D3 [25(OH)D] levels reduced the D component by 0.66 per each 10 ng/mL of vitamin D3 concentration. The percentage of children with active caries in rural areas is 91.07% (n = 51), which is significantly higher than the percentage of children with active caries in urban areas (81.54%, n = 53).To date, information regarding the potential possibility of reducing the incidence of dental caries by means of increasing the levels of vitamin D was sidelined by paediatricians and dentists alike. Therefore, this aspect of caries prevention should be highlighted.

StreszczenieRozwój cywilizacji i ciągła poprawa jakości życia prowadzi do zmiany w zachowaniach prozdrowotnych. Siedzący tryb życia oraz nadmiar spożywanych kalorii powoduje nadmierny przyrost tkanki tłuszczowej, prowadzący do nadwagi i otyłości. W ciągu ostatnich kilku lat problem ten stale narasta, stając się epidemią XXI wieku w Polsce i na całym świecie. Cel pracy. Porównanie stylu życia dzieci z prawidłową masą ciała oraz dzieci z nadwagą i otyłością. Metody i pomiary. Badaniami ankietowymi objęto 232 dzieci w wieku 2,5-18 lat (80 dzieci z prawidłowa masą ciała i 152 dzieci z nadwagą i otyłością). Wyniki. Stwierdzono większą częstość występowania otyłości u rodziców dzieci z nadmierną masą ciała (60,13%). Dzieci otyłe rzadziej spożywały posiłki w domu w porównaniu z dziećmi z prawidłową masą ciała (62,50% vs. 37,50%) i jadły nieregularnie. Częściej również próbowały zredukować masę ciała (34,87 vs.1,25%) stosując diety niskokaloryczne. Wnioski. Nadwaga i otyłość stwierdzana u rodziców ma duży wpływ na występowanie nadmiernej masy ciała u dzieci. Posiłki przygotowywane i spożywane w domu przyczyniają się do kształtowania dobrych nawyków żywienio-wych.Endokrynol.

The constant development of civilization and the continuous improvement of the quality of life lead to a change in healthy behaviors. A sedentary lifestyle and excess of calories contribute to an increase in fat tissue, leading to overweight and obesity. Over the past few years, this problem has been growing steadily and becoming an epidemic of the 21 st century in Poland and around the world. Objectives. Comparison of the lifestyle of children with normal weight and children with overweight and obesity. Materials and methods. The study included 232 children at the age 2,5-18 years (80 children with normal body weight and 152 children with overweight and obesity). Results. There was a higher incidence of obesity in parents of children with excessive body weight (60.13%) and less physical activity. Obese children rarely ate lunch at home, compared with children with normal weight (62.50% vs. 37.50%), and and had irregular mealtimes. They more often tried to reduce their body weight (34,87 vs.1, 25%) using low--calorie diets. Conclusions. Overweight and obesity observed in the parents has a major impact on the incidence of excessive weight with children. Meals prepared and eaten at home contribute to the development of good eating habits.
