Assessments of Energy, Macro and Micronutrient Intakes in Children and Adolescents With Type 1 Diabetes Mellitus
(Marmara Univ, Fac Medicine, 2023) Özkaya, Şebnem Özgen; Ozkaya, Sebnem Ozgen; Beslenme ve Diyetetik Bölümü
Objective: This study aims at examining dietary intake in children and adolescents with type 1 diabetes mellitus (DM) and comparing the results with national dietary intake recommendations. Patients and Methods: One hundred fifty children and adolescents (52.7% female) with an average age of 12.2 +/- 3.1 years and with type 1 DM who were followed by the Pediatric Endocrinology Polyclinic participated in the study. Three-day food intake records and clinical information regarding the type 1 DM condition of the participants were obtained. Results: No gender-related significant difference was found among the participants regarding food intake. The percentage of energy derived from fat (average 39.6%) and saturated fat (16.1%) were higher than the recommended levels in both gender groups. The percentage of energy derived from carbohydrates (female 44.1 +/- 5.7%, male 43.0 +/- 6.8%) was below the recommended levels. The dietary fiber intake in children aged 6-10 years with type 1 DM met recommendations, whereas, it was below the recommended levels in other age groups. Micronutrient inadequacy was common in children and adolescents with type 1 DM. Conclusions: The authors believe that guidelines and programs are needed for children and adolescents with type 1 DM to reduce total fat and saturated fat intake, increase carbohydrate and dietary fiber intake up to the recommended levels, and prevent multiple micronutrient inadequacies.

Nutritional Experiences of Turkish University Students With Type 1 Diabetes: a Qualitative Study
(Bmc, 2025) Ozkaya, Sebnem Ozgen; Ozkaya, Volkan; Gedikli, Erman; Garipagaoglu, Muazzez
BackgroundThis study was performed in order to describe the nutritional experiences of university students with Type 1 diabetes who try to carry on their educational and social lives together in diabetes self-management.MethodsIn this descriptive and qualitative study, face-to-face and semi-structured in-depth interviews were performed with 15 university students with Type 1 diabetes, aged 18-30, resided in Istanbul, who were diagnosed with Type 1 diabetes at least 5 years ago. The data collection process was performed by the researchers. The interviews were recorded and transcribed. The data collected in accordance with the phenomenological approach were processed using guided content analysis.ResultsIn the interview with the participants, whose mean age was 21.86 +/- 2.03 years and 66.7% of those were female, 6 themes were listed as positive and negative experiences of students in diabetes management in the university environment, general nutritional preferences, nutritional attitudes in non-routine and social environments, regular nutrition and quality of campus life, nutrition during the exercise/sports period, university support and students' expectations from the environment and explained by their sub-dimensions.ConclusionThe change in living conditions with the transition to campus life, the new social environment, individualization and academic responsibilities make diabetes self-management a challenging, complex and supportive process. This study might guide the enhancement of university students' living conditions with diabetes.

Obesity Risk Factors in Turkish Preschool Children: a Cross-Sectional Study
(Cukurova Univ, Fac Medicine, 2022) Garipağaoğlu Denizhan, Muazzez; Ozkaya, Volkan; Özkaya, Şebnem Özgen; Beslenme ve Diyetetik Bölümü
Purpose: The present study aims to identify the potential risk factors - pre and post-pregnancy, children's, parental, and environmental factors - concerning obesity in Turkish preschool children.Materials and Methods: The cross-sectional study was conducted with 538 children aged 3-5 and their mothers in 25 private and public kindergartens using a face-to-face survey. Demographic, anthropometric, nutrition, sleep, and physical activity information during pregnancy, infancy, and preschool periods were evaluated. Two-day food records and anthropometric measurements of the children were collected.Results: The prevalence of overweight and obesity in preschool children was found to be 27.0%. Among the 28 potential risk factors examined, pre-pregnancy obesity (odds ratios (OR):1.108, confidence interval (CI): 1.042-1.179), post-pregnancy obesity (OR:4.350, CI: 2.053-9.217), caffeine intake >200 mg/day during pregnancy (OR:1.588, CI:1.031-2.446), father with obesity (OR: 1.089, CI: 1.027-1.155), enrolling a private rather than a public kindergarten (OR: 2.093, CI:1.298-3.376), fast eating (OR:3.355, CI: 1.175-9.583 min), short lunch duration (OR:0.966, CI:0.934-0.998), daily sleep of <10 hours (OR:2.522, 1.439-4.421), and finally screen time of >2 hours/day (OR:1.560, CI:1.012-2.405) were found to be significantly correlated with obesity in preschool children.Conclusion: Parental obesity, caffeine intake during pregnancy, eating speed, daily sleep, and screen time were determined as obesity risk factors in Turkish preschool children. Identifying maternal and child risk factors in early childhood, regulating lifestyle and obesogenic environment can be protective against obesity.

Relationship Between Visceral Adiposity Index and Glycemic and Metabolic Control in Children and Adolescents With Type 1 Diabetes Mellitus
(Springer London Ltd, 2024) Özkaya, Şebnem Özgen; Ozkaya, Sebnem Ozgen; Adal, Servet Erdal; Beslenme ve Diyetetik Bölümü
BackgroundVisceral Adiposity Index (VAI) is a gender-specific mathematical model based on BMI, waist circumference (WC) and lipid parameters. No study has yet examined the relationship between this index and the glycemic and metabolic parameters in children and adolescents with Type 1 Diabetes Mellitus (DM). The current study aims at examining the relationship between glycemic and metabolic control and VAI in children and adolescents with Type 1 DM.MethodsA total of 150 children and adolescents aged 6-18 years with Type 1 DM were included in this study. Anthropometric, glycemic and metabolic parameters were examined. VAI was calculated using gender-specific formulas. Statistical analysis was done by SPSS version 23.ResultsThe average age of the participants was 12.2 +/- 3.1 years (females 53.0%). The females had higher rates of VAI, microalbuminuria and hypertension than males. Participants of both gender with higher VAI quartiles had higher anthropometric measurements, insulin usage, low-density lipoprotein cholesterol (LDL-C), triglycerides and urine microalbumin and had poor glycemic control. Sex adjusted correlation analysis showed that VAI is negatively correlated with estimated glucose disposal rate (eGDR), and positively correlated with insulin dose, LDL-C, triglycerides, glycosylated hemoglobin (HbA1c) and microalbuminuria.ConclusionThe present paper is the first study examining the relationship between Type 1 DM and VAI. Higher VAI values in children and adolescents with type 1 DM may adversely affect glycemic and metabolic control. VAI can be a useful and new method in evaluating glycemic and metabolic control in children and adolescents with Type 1 DM.
