Nutritional therapy is essential for achieving proper metabolic control in type 1 diabetes (T1D) treatment. In our center, nutritional education endorses the Mediterranean diet known to prevent diabetes-related complications and improve overall health. Nevertheless, the continuous attention given to dietary restrictions can lead to disordered eating behaviors (DEB) in adolescents with T1D, which are associated with poor glycemic control and long-term complications [1] . The COVID-19 pandemic, especially during lockdowns, has a profound emotional impact on adolescents. With the disrupted school routine, reduced extracurricular activities, and increased use of social media, adolescents are more vulnerable to developing DEB [2] .

This study examines whether DEB was exacerbated in adolescents with T1D during the COVID-19 pandemic and whether changes in glycemic control and dietary habits related to the Mediterranean diet occurred.

This is an observational, longitudinal study evaluating the dietary habits of adolescents aged 15-19 years with T1D for more than one year, treated at the diabetes clinic in Schneider Children's Medical Center of Israel. As a routine in our clinic, adolescents aged 15-19 complete a DEB screening tool and a nutritional questionnaire. The Diabetes Eating Problem Survey-Revised (DEPS-R) is used to assess the risk of DEB (range 0-80; score > 20 indicates a high risk for DEB) [3] and the Mediterranean Diet Quality Index (KIDMED) questionnaire for children and adolescents to assess the diet quality according to the Mediterranean diet pattern (range -4 to 16 points) [4] .

The participants' dietary habits before the COVID-19 pandemic (February 2019 to January 2020) and near the end of the first lockdown (May to June 2020) were studied. The study participants were recruited near the end of the first lockdown, where they completed the questionnaires for the second time. Exclusion criteria were medical conditions related to nutritional status, psychiatric disorders, or inability to complete the study questionnaires.

Clinical data, including age, gender, weight, height, and glycated hemoglobin (HbA1c), were retrieved from the patient's medical record at baseline and re-measured at the first visit after the lockdown. Body mass index (BMI) was calculated as weight (kg)/height 2 (m 2 ) and standardized to age and gender. BMI above the 85th percentile for age and gender was classified as overweight or obese, and below the 5th percentile as underweight. Capillary HbA1c was measured by the DCA 2000 analyzer (Bayer Diagnostics Inc). The Rabin Medical Center ethics committee approved the study. Participants or their legal guardians provided informed consent approving their participation. was used for analysis. The mean differences between the questionnaire scores were analyzed using paired t-tests. The associations between the questionnaires scores and potential explanatory variables were analyzed using independent t-tests or Pearson's correlations. Multiple linear regression analysis was performed to examine the association between the changes in DEPS-R scores and potential explanatory variables. An alpha level of 0.05 was used for all statistical analyses.

Thirty-four adolescents (mean age 17.1 ± 1.1 years; 38% females) were included in the study. The average time between baseline and follow-up was 11.5 + 4.3) months. DEPS-R score significantly increased during the COVID-19 lockdown (12.7 ± 7.4 vs. 16.0 ± 10.0, p = 0.01) ( Table 1) . Eleven participants had a score > 20 points, indicating a high risk for DEB, compared to six participants at baseline (p = 0.18). No significant correlations were found between the changes in DEPS-R score and age, gender, HbA1c, or BMI. There was no change in KIDMED scores, and no correlations were found between changes in KIDMED scores and age, gender, HbA1c, or BMI.

This study examined changes in DEB and dietary habits in adolescents with T1D during the COVID-19 pandemic. Our results suggest that the COVID-19 lockdown negatively affected the eating behaviors of adolescents with T1D, doubling the probability of having DEB. The pandemic did not affect glycemic control, BMI, or adherence to the Mediterranean diet.

The COVID-19 pandemic has been shown to increase the incidence of eating disorders among adolescents [5] . Our results suggest that the COVID-19 exacerbated DEB in adolescents with T1D.

Several factors such as lockdowns, restrictions, and altered sleeping patterns can explain the increase in DEB. Also, social isolation and intensive media and social media exposure may increase stress and anxiety, which adversely affect eating habits [2] .

In our study, the drive for thinness and changes in meal patterns were the main factors aggravating DEB. Although no significant alterations in BMI were observed, more than a quarter of the participants perceived themselves as gaining weight during the pandemic. The changes in meal patterns can be related to the fear of the disease and its complications, motivating the parents to be more careful about their children's diet on the one hand. On the other hand, the increased parental presence may have caused more stress and a desire to eat alone. Glycemic control and dietary patterns did not change significantly in our patients. Thus, we believe that the worsening in DEB is not related to diabetes management but to eating pathology and the drive for thinness. The main limitation of our study is its small sample size. However, the study's design enabled us to dissect the pandemic's effect on the participants' eating behaviors as the baseline questionnaires were completed before the pandemic. Nevertheless, further studies on larger populations are needed to confirm our findings.

In conclusion, our study shows an exacerbation in DEB among adolescents with T1D during the COVID-19 outbreak. The exacerbation is likely due to eating pathology and the drive for thinness and not because of poor diabetes management. As the COVID-19 pandemic is far from over, our study emphasizes the importance of routine screenings for DEB in adolescents with type 1 diabetes.
