Premature born AGA and SGA children do not have insulin resistance when compared to term children if they have made a catch-up growth appropriate for their target height and have normal BMI. The similar insulin levels in preterm SGA and preterm AGA children together with increased insulin levels in term SGA children points to the fact that it is the intrauterine restriction in the third trimester that has an adverse effect on future adverse metabolic outcome.

SGA children with CUG and with no obesity have higher insulin levels compared to AGA children. Both SGA birth and recent size seem to have an effect on serum adiponectin levels in childhood.

LGA children have higher insulin and lower adiponectin levels than AGA children in spite of similar BMI. Adiponectin is a better indicator of insulin resistance in LGA children at prepubertal ages and is affected by birth weight.

Background: Ghrelin, the natural ligand of the GH secretagogue receptor, has potent orexigenic effect. Ghrelin levels are negatively associated with insulin secretion, increased in anorexia, and reduced in obesity. Increased ghrelin levels may be associated with early postnatal growth in preterm born children. Objective: Aim of this study was to evaluate ghrelin and insulin levels at prepubertal ages in preterm born children born appropriate for gestational age (AGA) or small for gestational age (SGA) and relationships with catch-up growth (CUG) in a prospective cross-sectional study. Methods: Eighty-four preterm born children grouped as preterm SGA (nZ28) and preterm AGA (nZ56) were evaluated at age 4.7G0.2 and 4.7G0.1 years with respect to their ghrelin and insulin levels. Their data were compared with that of body mass index matched term SGA (nZ35) and term AGA (nZ44) children of age 4.6G0.2 and 3.8G0.1 years. All children had height appropriate for their target height. CUG was defined as the difference between birth size and recent size and expressed as D height and D weight SDS. Results: Preterm SGA and preterm AGA children had similar ghrelin levels (1717.0G166.9 and 1656.5G103.8 pg/ml), although D height and D weight SDS in preterm SGA were significantly higher than in preterm AGA children (P!0.001). Ghrelin levels in both preterm groups were higher than term SGA (469.2G132.5 pg/ml) and term AGA children (659.6G143.3 pg/ml; P!0.001 for all). D Height and D weight SDS of the term SGA children were similar to that of preterm SGA children. Ghrelin did not have correlation with CUG but had inverse correlation with recent anthropometric indices. Insulin was significantly higher in term SGA children than other groups (P!0.001). Conclusions: Preterm children have higher ghrelin levels at prepubertal ages regardless of the magnitude of their CUG. Term SGA children, on the other hand, behave differently and have lower ghrelin levels than preterm children at prepubertal ages, which may be related to elevated insulin levels in this group.

Objective : During the coronavirus disease 2019 pandemic, lockdown measures and difficulties in accessing healthcare have impacted asthma management in children. This study aimed to determine the evaluation of the impact of environmental changes on asthma control in children, access to health care, and treatment adherence in early coronavirus disease 2019 lockdown. Materials and Methods: The study included children with asthma aged 6-11 years. A survey form was administered to the patients who visited the pediatric allergy outpatient clinic between June 1 and 30, 2020. The survey acquired demographic information about the children and their families as well as information about their asthma symptoms, how they reached healthcare services, and adherence. The childhood asthma control test was administered. The P values <.05 were considered significant. Results: The study included a total of 123 children (female/male : 48/75) with a mean age of 8.4 ± 1.9 years. According to the mothers’ self-report, it was found that 78% of the patients were not able to follow-up routinely, 19.5% were non-adherence to treatment, and 16.2% were poorly controlled asthma. It was found that, based on childhood asthma control test scores, asthma control was better during the pandemic lockdown period ( P = .001). Asthma symptoms were better in 41.5% of the patients compared to the previous months and in 53.7% compared to the same period last year. Conclusion: Our study found that the children’s asthma was controlled although most of them did not have their follow-up visits, and poorly controlled asthma was higher in older children in early coronavirus disease 2019 lockdown.
