Adverse childhood experiences (ACE) have been associated with a greater prevalence of risky behaviors and chronic health conditions, such as diabetes in adulthood. While adolescents with risk taking behaviors experience worsening of diabetic metabolic control, it is yet to be determined whether glycemic management in children and adolescents is negatively and independently influenced by ACEs. This study examines the relationship between ACEs in children and adolescents with type 1 diabetes (T1DM) and glycemic control, BMI and lipids. For such children, we hypothesized that hemoglobin A1c (HbA1c) is positively correlated with ACE scores. Parents of children (age 2–18 years) with T1DM completed a validated ACE questionnaire. The associations between parent and child ACE score and HbA1c, lipids and BMI z-scores were assessed using linear regression. The prevalence of any ACE was 27.9% among children and 49.0% among parents. HbA1c was significantly higher in children who had exposure to three or more ACEs (β:0.63 (4.5 mmol/mol); p = 0.02), in those who had a parent exposed to four or more ACEs (β:0.87 (7.2 mmol/mol); p = 0.03), in children who had exposure to household incarceration (β:0.62 (4.4 mmol/mol); p = 0.05) and children who witnessed or had been victim of violence in the neighborhood (β:0.71 (5.4 mmol/mol); p = 0.02). ACEs were highly prevalent among children with T1DM and had a positive association with glycemic control.

Abstract Background Severe obesity is associated with a number of cardiometabolic risk factors. Thyroid-stimulating hormone (TSH) levels are often slightly increased in children with obesity. The clinical significance of the mild elevation in TSH in children with obesity is unclear. Objective To examine the association between TSH and lipids in children with severe obesity. Methods We performed a retrospective analysis of records of children with severe obesity with simultaneous measurements of TSH and lipids. Children with TSH <0.3 mIU/L and ≥10 mIU/L were excluded. The relationship between TSH and lipids was evaluated using univariate/multiple variable linear and logistic regression. Results The study included 834 children (age 13.8 ± 4.1 years, males 46%, body mass index [BMI]: 36.9 ± 7.6 kg/m2; BMI z-score 2.6 ± 0.4). Seventy-four (8.9%) children had TSH between 5 and <10 mIU/L (high TSH [HTSH]). TSH was positively associated with non-high-density lipoprotein (HDL) cholesterol (β: 1.74; 95% confidence interval [CI] 0.29–3.20, p = 0.02). Total cholesterol and non-HDL cholesterol were higher in males with HTSH compared to those with normal TSH (175.5 vs. 163.5 mg/dL, p = 0.02 and 133.7 vs. 121.4 mg/dL, p = 0.02, respectively). The odds of elevated non-HDL cholesterol (≥145 mg/dL) was higher in males with HTSH relative to those with normal TSH (odds ratio [OR]: 2.78; 95% CI 1.35–5.69, p = 0.005). Conclusions TSH levels were positively associated with non-HDL cholesterol in children with severe obesity. Males with mildly elevated TSH had higher total cholesterol and non-HDL cholesterol compared to males with normal TSH. Further studies are warranted to determine if levothyroxine therapy would result in improvement in total cholesterol or non-HDL cholesterol in children with severe obesity with mildly elevated TSH.

AbstractRationale, aims, and objectivesWaist circumference (WC) and waist‐to‐height ratio (WHtR) are superior surrogate markers of central obesity than body mass index. However, WC is not measured routinely in paediatric clinics. The objective of this study was to implement measurement of WC during routine assessment of children in an ambulatory outpatient clinic setting and subsequent dissemination of cardiometabolic risk counselling in children with central obesity (defined as WHtR ≥0.5).MethodProspective cohort of patients aged 6 to 20 years. Study period was divided into three phases: baseline (3 months), process improvement (2 months), and implementation (6 months). Define‐Measure‐Analyse‐Improve‐Control (DMAIC) strategy was applied. Measurement of WC was implemented as a component of the physical examination in patients. Outcome measures were (1) improvement in frequency of WC measurement and (2) utilization of WHtR in cardiometabolic risk counselling.ResultsWaist circumference was not measured in any patient during baseline phase (n = 551). During process improvement phase, of the total 347 patients, WC was measured in 35% vs target of 30%. In the implementation phase, WC was measured in 37% patients (365 out of 964). Of these 365 patients, 175 (48%) had elevated WHtR, and 73% of them (n = 128) were counselled about their increased cardiometabolic risk.ConclusionsApplication of an evidence‐based DMAIC protocol led to significant improvement in assessment for central obesity in an ambulatory clinic practice and appropriate counselling regarding cardiometabolic risk reduction in children and adolescents with central obesity over an 8‐month period. Meticulous planning and execution, frequent reinforcement, and integrating feedback from the involved multi‐disciplinary team were important factors in successful implementation of this quality improvement project.

Abstract Background Females with congenital adrenal hyperplasia (CAH) and atypical genitalia often undergo complex surgeries; however, their outcomes remain largely uncertain. Methods We searched several databases through 8 March 2016 for studies evaluating genital reconstructive surgery in females with CAH. Reviewers working independently and in duplicate selected and appraised the studies. Results We included 29 observational studies (1178 patients, mean age at surgery, 2.7 ± 4.7 years; mostly classic CAH). After an average follow-up of 10.3 years, most patients who had undergone surgery had a female gender identity (88.7%) and were heterosexual (76.2%). Females who underwent surgery reported a sexual function score of 25.13 using the Female Sexual Function Index (maximum score, 36). Many patients continued to complain of substantial impairment of sensitivity in the clitoris, vaginal penetration difficulties, and low intercourse frequency. Most patients were sexually active, although only 48% reported comfortable intercourse. Most patients (79.4%) and treating health care professionals (71.8%) were satisfied with the surgical outcomes. Vaginal stenosis was common (27%), and other surgical complications, such as fistulas, urinary incontinence, and urinary tract infections, were less common. Data on quality of life were sparse and inconclusive. Conclusion The long-term follow-up of females with CAH who had undergone urogenital reconstructive surgery shows variable sexual function. Most patients were sexually active and satisfied with the surgical outcomes; however, some patients still complained of impairment in sexual experience and satisfaction. The certainty in the available evidence is very low.

SummaryBackgroundThere is a lack of consensus on the cardiometabolic consequences of mild subclinical hypothyroidism (SCH) among children. The objective of the current study was to compare lipid profiles in children with mild SCH with those of euthyroid children.Study DesignRetrospective medical record review.PatientsChildren (ages 2‐18 years) who had undergone simultaneous measurement of TSH, free thyroxine (T4) and lipids. Lipids in children with mild SCH (TSH 5‐<10 mIU/L and normal free T4, n = 228) were compared with those in euthyroid children (n = 1215).ResultsTSH level was positively associated with total cholesterol and nonhigh density lipoprotein (non‐HDL) cholesterol [β 0.05(0.03‐0.08), P < .0001 and β 0.05(0.03‐0.08), P < .0001, respectively]. Total cholesterol was significantly higher in children and adolescents with mild SCH compared with euthyroid children (4.43 ± 1.14 mmol/L vs 4.2 ± 0.85 mmol/L, P = .0005). Similarly, non‐HDL cholesterol level was also higher in children with mild SCH relative to euthyroid children (3.08 ± 1.14 mmol/L vs 2.91 ± 0.8 mmol/L, P = .001). The adjusted odds ratio of having elevated total cholesterol and elevated non‐HDL cholesterol was greater in children with mild SCH compared with euthyroid children (OR 1.88, 95% CI; 1.28‐2.73; P = .001 and 1.72, 95% CI 1.2‐2.5; P = .003, respectively). The presence of thyroid autoimmunity was not associated with higher rates of dyslipidaemia.ConclusionsMild SCH in children and adolescents was associated with higher rates of elevated total cholesterol and elevated non‐HDL cholesterol. Randomized placebo controlled studies are warranted to determine if treatment of mild SCH in children leads to improvement in lipid profile.

Severe obesity is associated with abnormal lipids and increased risk for cardiovascular disease. Obesity is a risk factor for vitamin D deficiency. We examined relationship between 25-hydroxy vitamin D (25(OH)D) concentrations and lipids in children with severe obesity. Medical records of 376 children were reviewed. Linear regression models and logistic regression were used to examine the relationship between 25(OH)D and lipids after adjustment for age, gender, season of blood draw, body mass index (BMI) z-score, and BMI % of 95th percentile. Two-hundred sixty-three out of 376 children (70%) had 25(OH)D concentrations < 30 ng/mL. Concentrations of 25(OH)D were positively correlated with those of high-density lipoprotein cholesterol (HDL-C) (r2 = 0.08, r = 0.22, β = 0.16, 95% CI = 0.05–0.27, p = 0.004). HDL-C was lower in children with 25(OH)D < 30 ng/mL (n = 263) compared to those with 25(OH)D ≥ 30 ng/mL (n = 113) (41.3 ± 10.2 vs. 46.4 ± 12 mg/dL, p < 0.0001). Children with 25(OH)D concentrations < 30 ng/mL had greater adjusted odds of low HDL-C (<40 mg/dL) compared with those with 25(OH)D ≥ 30 ng/mL (47.9% vs. 29.2%, OR 2.15 (1.33–3.51), p = 0.0019). Total cholesterol and non-HDL-C were not correlated with 25(OH)D concentrations. Vitamin D deficiency is highly prevalent in children with severe obesity. Prospective clinical trials are warranted to determine if vitamin D supplementation can improve HDL-C and potentially decrease risk for cardiovascular disease in children with obesity.
