ABSTRACT Background: Type 1 Diabetes Mellitus (T1DM) is the most common endocrine-metabolic disease in children. It is associated with vascular and neuropathic complications, and may also affect growth and development. Objective: To correlate the metabolic control and disease duration with growth and puberty in patients with T1DM followed in a Pediatric Endocrinology Outpatient Clinic. Subjects and methods: Retrospective analysis. Sample obtained from patients with T1DM followed in Hospital Santa Maria Pediatric Endocrinology Outpatient Clinic (Lisbon - Portugal) since 1994 until March 2011. Inclusion criteria: patients diagnosed before the onset of puberty and who had attained their final height during the follow-up. Variables: sex, age, weight and height at diagnosis and final, parents' height, growth velocity, pubertal height gain, age at menarche and metabolic control during puberty. Results: 39 patients, 51% female, 82% diagnosed less than five years before puberty. Fifty-four percent presented an average HbA1c between 8-10%, what we considered reasonable. There seems to be a trend towards an inverse association between HbA1c and the maximum speed of growth and pubertal height gain, although not statistically significant. These patients were taller than average at diagnosis (z-score: male 0.9; female: 0.5) and lost height during puberty, yet attained final heights within normal range and matching their target heights. Conclusions: Although HbA1c seems to negatively influence maximum growth rate and pubertal height gain, there was no compromise in final height in this group of patients.

    ABSTRACT: New charts for height, weight, height velocity, and weight velocity are presented for clinical (as opposed to population survey) use. They are based on longitudinal-type growth curves, using the same data as in the British 1965 growth standards. In the velocity standards centiles are given for children who are early- and late-maturing as well as for those who mature at the average age (thus extending the use of the previous charts). Limits of normality for the age of occurrence of the adolescent growth spurt are given and also for the successive stages of penis, testes, and pubic hair development in boys, and for stages of breast and pubic hair development in girls.

    ABSTRACT: The aims of this study were to assess the physical growth and pubertal development in a group of diabetic children and to evaluate the effect of height at diagnosis, duration of illness, and degree of glycemic control on final height and sexual maturation. A cohort of 72 Sudanese diabetic children, 7-13 years of age at diagnosis, was followed longitudinally from the onset of diabetes until the attainment of final height. The mean height standard deviation scores (SDS) at diagnosis were 0.04 in boys and -0.15 in girls, which was greater than their genetic target height (GTH). The growth velocity between diagnosis and final height was slow, with significant reduction in pubertal growth spurt. The mean final height attained by these children was lower than their GTH, a finding that contradicts most of the recently published reports. The average age at menarche in girls (15.1 years) and the mean age of full sexual maturation in boys (17.2 years) were significantly delayed in this group of diabetic patients. This retardation in physical growth and pubertal development was positively correlated with the duration of diabetes before the onset of puberty and glycated haemoglobin (HbA1c) concentration. The majority of these patients were thin at diagnosis of diabetes, with median body mass index (BMI) <22, but showed a remarkable, progressive weight gain during puberty, which was more evident in girls. The weight gain was independent of weight at diagnosis and duration of diabetes, but was positively correlated with the daily dose of insulin and HbA1c concentration. Conventional therapy of diabetic children is associated with impairment of physical growth and delayed sexual maturation.

    ABSTRACT: Insulin release and growth are intimately connected. The aim of the present study was to investigate height and weight in diabetic children from birth to onset of Type 1 (insulin-dependent) diabetes mellitus compared to that in referent children. Data on height and weight were collected from mailed questionnaires and from growth records obtained from the child health clinics and schools in 337 recent-onset diabetic children, 0-14 years old, and from 517 age-, sex-, and geographically matched referent children. A total of 9002 paired height and weight observations were collected. The anthropometric development of the children was expressed as standard deviation scores using the National Center for Health Statistics/Centers for Disease Control (NCHS/CDC) growth reference material. On the average, the diabetic children were consistently taller than the referent children, a finding more pronounced among the boys. The diabetic boys were significantly taller from 7 to 1 years before the clinical onset of the disease, regardless of age at onset. A similar tendency was found for the girls. When mean height from 5 to 1 years before onset was used as a possible risk factor for diabetes, a linearly increasing trend in the odds ratio was found for diabetes in boys (odds ratio = 1.0; 1.57; 2.46 for height standard deviation score values less than 0; 0-1 and greater than 1, respectively; p = 0.002 for trend). A similar, but statistically not significant, tendency was found for girls (odds ratio = 1.0; 1.44; 1.43). As regards height increment from birth similar trends in odds ratios were found.(ABSTRACT TRUNCATED AT 250 WORDS)
