Socio-Ecologic Influences on Weight Trajectories Among Children with Obesity Living in Rural and Urban Settings.

Background: Childhood obesity is a risk factor for poor cardiovascular, metabolic, and respiratory health. The studies examining influences of socio-ecologic factors on weight trajectories using longitudinal data are limited, often examine single measures (e.g., proximity to parks), and have not examined the specific trajectories of children with obesity. Methods: We examined influences on weight among 1518 children, 6-12 years of age, who had obesity using body mass index (BMI) criteria. BMI slope trajectories were categorized as decreasing, flat, or increasing, with a median of 2.1 years of follow-up. We examined socio-ecologic exposures, stratified by rural and urban settings, using census tracts to map indices, including food access, proximity to parks, normalized difference vegetation index, and area deprivation index (ADI). We used ordinal logistic regression to examine the associations between the socio-ecologic factors and BMI trajectories. Results: Among the 1518 children, 360 (24%) had a decreasing BMI trajectory with the remainder having flat (23%) or increasing (53%) trajectories. Children in rural areas were more likely to live in high disadvantage areas, 85%, compared with urban children, 46%. In the multivariable ordinal model, living in a lower ADI census tract had a 0.78 (95% CI 0.61-0.99) lower odds of being in an increasing BMI slope group, and no other socio-ecologic factor was associated. Conclusions: The area deprivation index captures a range of resources and social context compared with the built environment indicators, which had no association with BMI trajectory. Further work examining how to develop effective interventions in high deprivation areas is warranted.

Predictors of Virologic Failure Among a Cohort of HIV-infected Children in Southern Ethiopia.

BACKGROUND: Optimal care for children with HIV infection includes timely assessment of treatment failure. Using HIV viral load to define treatment failure remains a challenge in resource-limited settings. METHODS: Children with HIV infection who were already on or starting first-line antiretroviral therapy were enrolled and followed over time. We examined clinical and immunologic predictors of virologic failure (VF), defined as consecutive viral load measurements > 1000 copies/mL (VF). Children were followed every 6 months with clinical assessments, immunologic assays and viral load testing until treatment failure or up to 18 months. RESULTS: Of the 484 children with complete data, we observed a prevalence of 15% who had VF at enrollment, and 18 who developed VF over 10.5 person-years of follow-up for an incidence of 4.97 [95% CI: 3.04-7.70) per 100 person-years. Lower adherence, lower CD4 T-cell count, lower white blood cells count, lower platelets and a lower glomerular filtration rate were all associated with increased VF. However, in a multivariable analysis, renal function (estimated glomerular filtration rate < 90 mL/min), odds ratio: 11.5 (95% CI: 1.5-63.7), and lower adherence, odds ratio: 3.9 (95% CI: 1.1-13.4), were the only factors associated with development of VF. CONCLUSIONS: We identified a significant risk of VF in children with HIV infection in a prospective cohort study in southern Ethiopia and limited predictive value of clinical variables for VF. This provides further evidence that rapid and reliable viral load testing is needed to adequately address the HIV epidemic, along with implementation of adherence interventions in sub-Saharan Africa.

Weight outcomes in children with developmental disabilities from a multidisciplinary clinic.

BACKGROUND: Children with developmental disabilities experience disparately high rates of obesity yet there are few reports detailing clinical outcomes for this population. AIM: To describe outcomes of obesity treatment for children with developmental disabilities and a comparison group of children without developmental disabilities. METHODS AND PROCEDURES: We examined weight outcomes of children with and without developmental disabilities seen in a family-centered, multidisciplinary treatment center over a ten-year period. We stratified by age and developmental disability diagnosis. We assessed whether intake demographic or health behavior data was associated with successful reduction of adiposity over six and twelve month follow-up periods, using a ≥5% absolute reduction in percent over the 95th percentile body mass index (BMIp95) as the primary outcome. OUTCOMES AND RESULTS: Over a ten-year period, 148 of 556 children in the obesity clinic (27 %) had a developmental disability. In children <12 years of age, 36 % of children with developmental disabilities reduced their adiposity compared with 18 % of children without developmental disabilities at six months, p = .01. This pattern continued at twelve months. Active transport to school was associated with reduced adiposity for those without a disability. Older children with disabilities rarely had a significant reduction (2 of 26 children), and they took more medications with weight-related side effects. CONCLUSIONS AND IMPLICATIONS: Younger children with developmental disabilities experienced relative success in reducing their adiposity. Challenges to addressing obesity in this population include structural barriers to physical activity and medications for behavioral management with weight-related side effects.

The Impact of Malnutrition on Hospitalized Children With Cerebral Palsy.

Children with cerebral palsy (CP) and other medical complexity comprise an outsized proportion of health care use. In this review, we describe the current science of assessment of nutritional status for children with CP, outline a systematic approach to assessing their nutritional status, delineate ramifications of malnutrition on hospitalization-associated outcomes, and identify knowledge gaps and means of addressing those gaps using quality improvement and clinical research tools. Methods to accurately assess body composition and adiposity in this population by using skinfolds, age, sex, and activity level are available but are not widely used. There are limitations in our current method of estimating energy needs in children with CP, who are at higher risk of both obesity and micronutrient deficiencies. There is some evidence of an association between malnutrition, defined as either underweight or obesity, and hospitalization-associated outcomes in children generally, although we lack specific data for CP. The gaps in our current understanding of optimal nutritional status and between current science and practice need to be addressed to improve health outcomes for this vulnerable patient population.

Vancomycin Dosing in Children With Overweight or Obesity: A Systematic Review and Meta-analysis.

CONTEXT: Vancomycin is a medication with potential for significant harm with both overdosing and underdosing. Obesity may affect vancomycin pharmacokinetics and is increasingly common among children. OBJECTIVE: We aimed to determine if children with overweight or obesity have increased vancomycin trough concentrations with total body weight (TBW) dosing compared with children with normal weight. DATA SOURCES: We conducted a search of Medline and Medline In-Process & Other Non-Indexed Citations from 1952 (the year vancomycin was discovered) to November 2017. STUDY SELECTION: Search terms included vancomycin, body weight, and body composition terms and were limited to children. Studies were reviewed and screened by ≥2 reviewers. DATA EXTRACTION: The primary outcome was vancomycin level. Data were extracted by 2 reviewers. We performed quality assessment using the Newcastle-Ottawa quality assessment scale. RESULTS: We identified 271 records. After abstract and full-text screening, we identified 7 studies for full review. Six of the 7 studies used a matched case-control design, although there was significant variation in study methodology. Four of the 7 studies were included in a meta-analysis, which revealed a small but significant difference in vancomycin trough levels between children with normal weight and children with overweight or obesity when dosed by using TBW (N = 521; mean difference 2.2 U [95% confidence interval: 1.0-3.4]). CONCLUSIONS: High-quality data to guide vancomycin dosing in children with obesity are lacking. More studies evaluating dosing strategies in children with obesity are warranted because using TBW to dose vancomycin may lead to higher vancomycin concentrations and potential toxicity.

HIV and cART-Associated Dyslipidemia Among HIV-Infected Children.

BACKGROUND: Persistent dyslipidemia in children is associated with risks of cardiovascular accidents and poor combination antiretroviral therapy (cART) outcome. We report on the first evaluation of prevalence and associations with dyslipidemia due to HIV and cART among HIV-infected Ethiopian children. METHODS: 105 cART naïve and 215 treatment experienced HIV-infected children were enrolled from nine HIV centers. Demographic and clinical data, lipid profile, cART type, adherence to and duration on cART were recorded. Total, low density (LDLc) and high density (HDLc) cholesterol values >200 mg/dL, >130 mg/dL, <40 mg/dL, respectively; and/or, triglyceride values >150 mg/dL defined cases of dyslipidemia. Prevalence and predictors of dyslipidemia were compared between the two groups. RESULTS: prevalence of dyslipidemia was significantly higher among cART experienced (70.2%) than treatment naïve (58.1%) children (p = 0.03). Prevalence of low HDLc (40.2% versus 23.4%, p = 0.006) and hypertriglyceridemia (47.2% versus 35.8%, p = 0.02) was higher among cART experienced than naïve children. There was no difference in total hypercholesterolemia and high LDLc levels. Nutrition state was associated with dyslipidemia among cART naïve children (p = 0.01). CONCLUSION: high prevalence of cART-associated dyslipidemia, particularly low HDLc and hypertriglyceridemia was observed among treatment experienced HIV-infected children. The findings underscore the need for regular follow up of children on cART for lipid abnormalities.

Cohort profile: improving treatment of HIV-infected Ethiopian children through better detection of treatment failure in southern Ethiopia.

PURPOSE: The Ethiopian Paediatric HIV Cohort (EPHIC) was established to identify clinical and laboratory predictors of virological treatment failure to ultimately develop a clinical-immunological prediction rule with area under the curve of >0.80 for detecting first-line antiretroviral therapy failure (ARTF). It will also assess the performance of the current WHO guidelines for detection of first-line ARTF in children. PARTICIPANTS: Using a prospective cohort design, HIV-infected children and adolescents below the age of 18 years are followed every 6 months with a set of clinical and laboratory parameters at 6 hospitals in southern Ethiopia. For inclusion in the cohort, children should be on or are initiating first-line antiretroviral therapy (ART) and are not on second-line ART. Virological treatment failure is taken as the gold standard for the diagnosis of treatment failure. FINDINGS TO DATE: From October 2015 through April 2016, 628 children have been enrolled from 6 different HIV treatment centres across southern Ethiopia. The mean age at enrolment was 11.1 years and 47.6% were girls. Many of the children (88.6%) were at WHO Clinical stage 1 at time of enrolment. At enrolment, the mean duration on first-line ART was 45 months. Substitution of ART drugs was performed to nearly half (42.6%) of the cohort. Adherence as assessed with the Visual Analogue Scale was high (mean, 94.4%; SD=11.9). The median CD4 count of the cohort at enrolment was 741 with 3.1% having a value consistent with ARTF. FUTURE PLANS: Regular data uploads from the 6 hospitals in southern Ethiopia enable this cohort to be followed prospectively. The cohort will be completed in September 2017. The successful completion of this study will allow for better targeting of viral-load testing to those at highest risk in resource-poor settings and provide clinicians and policymakers with a practical prediction rule. ETHICS APPROVAL: SNNPR Regional Health Bureau Institutional Review Board.

Empiric Treatment of Acute Meningitis Syndrome in a Resource-Limited Setting: Clinical Outcomes and Predictors of Survival or Death.

BACKGROUND: Bacterial meningitis is a significant cause of morbidity and mortality in the developing world. However, limited research has focused on the diagnosis and management of meningitis in resource-limited settings. METHODS: We designed a prospective case series of children admitted to a large, academic referral hospital with acute meningitis syndrome. Data were collected on age, time of presentation, prior antibiotics, cerebrospinal fluid (CSF) parameters, antibiotic and steroid prescription, and clinical outcome. RESULTS: Data on 99 patients were collected and analyzed. Most of the patients were males, n=69 (70%), and were from a rural area, n=83 (84%). Incomplete vaccination was common, n=36 (36%) and many have evidence of malnutrition, n=25 (38%). Most patients, n=64 (72%), had received antibiotics prior to admission with a mean duration of symptoms of 4.9 days prior to admission. The CSF white blood cell (WBC) count was higher in those who had not received prior antibiotics though it was elevated in both groups. The CSF WBC count was not associated with survival; malnutrition and length of symptoms prior to admission were both associated with decreased survival. CONCLUSIONS: While use of antibiotics prior to obtaining CSF in patients with acute meningitis syndrome may decrease their CSF WBC count, it is not clinically significant. Many patients had a significant delay in presentation that had an effect on survival, This is a potentially modifiable risk factor despite the resourcelimited setting.

Factors Associated with Successful Mentoring of Parents Addressing Childhood Obesity: A Mixed Methods Approach.

Objective. Parents mentoring other parents as a behavioral intervention for child obesity is novel with limited data describing the experience and dynamics of this approach. This study aimed to describe the experiences of parent mentors and the self-efficacy and attitudes of their mentees in the context of a clinical trial for childhood obesity. Methods. The context for this study was a randomized clinical trial using either parent mentors or a community health worker engaging parents of obese children in behavioral change over six months. Parent mentors were interviewed at the mid-point of the intervention using a semistructured questionnaire to elicit their perceptions and experiences during the process of mentoring. Parent mentees completed a survey assessing their self-efficacy, perception of the parent mentor, and attitudes and beliefs related to their child's weight. Results. The qualitative analysis of parent mentor interviews indicated high commitment despite their nonprofessional status, facing challenges of engagement with fellow parents and attitudes of persistence and being nonjudgmental. The parent mentee ratings of parent mentors were overall very high and similar to the ratings of a community health worker (paraprofessional). Conclusion. The data suggest that a parent mentor model of intervention for child obesity is an acceptable mode of approaching behavior change in the Hispanic population around childhood obesity with potential for scalability if proven effective.

Perceptions of Weight and Health Practices in Hispanic Children: A Mixed-Methods Study.

Background. Perception of weight by parents of obese children may be associated with willingness to engage in behavior change. The relationship between parents' perception of their child's weight and their health beliefs and practices is poorly understood, especially among the Hispanic population which experiences disparities in childhood obesity. This study sought to explore the relationship between perceptions of weight and health beliefs and practices in a Hispanic population. Methods. A cross-sectional, mixed-methods approach was used with semistructured interviews conducted with parent-child (2-5 years old) dyads in a primarily Hispanic, low-income population. Parents were queried on their perceptions of their child's health, health practices, activities, behaviors, and beliefs. A grounded theory approach was used to analyze participants' discussion of health practices and behaviors. Results. Forty parent-child dyads completed the interview. Most (58%) of the parents of overweight and obese children misclassified their child's weight status. The qualitative analysis showed that accurate perception of weight was associated with internal motivation and more concrete ideas of what healthy meant for their child. Conclusions. The qualitative data suggest there may be populations at different stages of readiness for change among parents of overweight and obese children, incorporating this understanding should be considered for interventions.

Cross Sectional Characterization of Factors Associated with Pediatric HIV Status Disclosure in Southern Ethiopia.

BACKGROUND: Disclosure of HIV positive status to children and adolescents is a complex process. However, disclosure has been found to be associated with improved outcomes. The objective of the current study was to identify the predictors that facilitate disclosure of HIV status to children and adolescents and to study the reasons for non-disclosure. METHODS: Interviews of caregivers and reviews of records were done to collect data on caregiver and child information and details regarding the disclosure status of children. Bivariate analysis was done to test the association between HIV status disclosure and different caregiver and child factors. To identify the independent predictors of disclosure, we did multivariable logistic regression. RESULTS: A total of 177 children attending an HIV clinic were included. The mean age of the participants was 10.1 years (SD = 2.8), and about half (50.8%) were female. Most caregivers, 137 (77.8%) stated that disclosure of HIV status to children is important and should be done. However, disclosure had only been made to 59 (33.3%) of the participants. Child age more than 10 years [AOR = 6.7; 95%CI: 1.73-26.01], duration of HIV diagnosis of 5 years or more [AOR = 4.4; 95%CI: 1.26-15.06] and taking a zidovudin (AZT) based regimen [AOR = 3.5; 95%CI: 1.31-9.53] predicted HIV positive status disclosure. Additionally, length of treatment of caregivers of more than 14 years [AOR = 3.9; 95%CI: 1.07-14.61], disclosure of caregiver's HIV status to children and/or others [AOR = 4.7; 95%CI: 1.19-18.74], and the child's inquiry about their condition [AOR = 4.5; 95%CI: 1.16-17.43] increased the odds of disclosure. CONCLUSION: The rate of disclosure among HIV infected children in southern Ethiopia is low. Primarily time-based factors were associated with the probability of HIV positive status disclosure and a specific regimen which has not been found previously. Further qualitative research may elucidate more on these factors; educational strategies may address some of these determinants.

A positive deviance approach to early childhood obesity: cross-sectional characterization of positive outliers.

OBJECTIVE: Positive deviance methodology has been applied in the developing world to address childhood malnutrition and has potential for application to childhood obesity in the United States. We hypothesized that among children at high-risk for obesity, evaluating normal weight children will enable identification of positive outlier behaviors and practices. METHODS: In a community at high-risk for obesity, a cross-sectional mixed-methods analysis was done of normal weight, overweight, and obese children, classified by BMI percentile. Parents were interviewed using a semistructured format in regard to their children's general health, feeding and activity practices, and perceptions of weight. RESULTS: Interviews were conducted in 40 homes in the lower Rio Grande Valley in Texas with a largely Hispanic (87.5%) population. Demographics, including income, education, and food assistance use, did not vary between groups. Nearly all (93.8%) parents of normal weight children perceived their child to be lower than the median weight. Group differences were observed for reported juice and yogurt consumption. Differences in both emotional feeding behaviors and parents' internalization of reasons for healthy habits were identified as different between groups. CONCLUSIONS: We found subtle variations in reported feeding and activity practices by weight status among healthy children in a population at high risk for obesity. The behaviors and attitudes described were consistent with previous literature; however, the local strategies associated with a healthy weight are novel, potentially providing a basis for a specific intervention in this population.

Hypotonic versus isotonic fluids in hospitalized children: a systematic review and meta-analysis.

OBJECTIVE: To determine whether the use of hypotonic vs isotonic maintenance fluids confers an increased risk of hyponatremia in hospitalized children. STUDY DESIGN: A search of MEDLINE (1946 to January 2013), the Cochrane Central Registry (1991 to December 2012), Cumulative Index for Nursing and Allied Health Literature (1990 to December 2012), and Pediatric Academic Societies (2000-2012) abstracts was conducted using the terms "hypotonic fluids/saline/solutions" and "isotonic fluids/saline/solutions," and citations were reviewed using a predefined protocol. Data on the primary and secondary outcomes were extracted from original articles by 2 authors independently. Meta-analyses of the primary and secondary outcomes were performed when possible. RESULTS: A total of 1634 citations were screened. Ten studies (n = 893) identified as independent randomized controlled trials were included. Five studies examined subjects in the intensive care unit setting, including 4 on regular wards and 1 in a mixed setting. In hospitalized children receiving maintenance intravenous fluids, hyponatremia was seen more often in those receiving hypotonic fluids than in those receiving isotonic fluids, with an overall relative risk of 2.37 (95% CI, 1.72-3.26). Receipt of hypotonic fluids was associated with a relative risk of moderate hyponatremia (<130 mmol/L) of 6.1 (95% CI, 2.2-17.3). A subgroup analysis of hypotonic fluids with half-normal saline found a relative risk of hyponatremia of 2.42 (95% CI, 1.32-4.45). CONCLUSION: In hospitalized children in intensive care and postoperative settings, the administration of hypotonic maintenance fluids increases the risk of hyponatremia when compared with administration of isotonic fluids. For patients on general wards, insufficient data are available based on the reviewed studies, and individual risk factors must be assessed.

Food insecurity and obesity in New York City primary care clinics.

BACKGROUND: Hunger continues to be a problem in New York City; paradoxically, the city also has disproportionally high rates of diabetes and obesity. Some research suggests that food insecurity leads to obesity. METHODS: We undertook a cross-sectional "card study" in which doctors working at 8 New York City area primary care practices administered a brief, anonymous survey to patients they saw during clinic sessions. The survey included a 2-question food insecurity screen and questions about enrollment in nutrition assistance programs. Height and weight were also measured at the visit. RESULTS: Cards were completed for 558 patients (65.1% female; 74.7% adults; 78.5% conducted in English). Fifty-five percent of patients were receiving some form of food assistance. More than half of patients (51.7%) reported some degree of food insecurity. Of adult participants, 21.8% had normal weight, 29.1% were overweight, and 48.2% were obese. Food insecurity was significantly associated with increasing body mass index in women not receiving food assistance. There was no significant association between body mass index and food insecurity in children. DISCUSSION: In an urban population, overweight and obesity are very common as is food insecurity. We found an association between food insecurity and obesity only among women not receiving food assistance suggesting a possible protective role for food assistance. Providers should consider food insecurity in similar populations when trying to address obesity.

An analysis of the association between parental acculturation and children's medication use.

OBJECTIVES: We examined how Hispanic children, with stratification according to language to approximate acculturation, differed with respect to sociodemographic characteristics and medication use. We also examined how different factors were associated with the use of different classes of prescription medications. METHODS: We used data from the 2004 Medical Expenditure Panel Survey linked to the National Health Interview Survey. Independent variables were grouped as predisposing characteristics, enabling factors, perceived need, and evaluated need. Multivariate logistic regression was used to assess the impact of independent variables on the outcomes of overall and specific types of medication use. RESULTS: Hispanic, Spanish-interviewed children were less likely to have a usual source of care than were Hispanic, English-interviewed subjects. Both groups had lower odds of using any prescription medication, compared with white children, which was explained largely by having a usual source of care. The lower use of psychiatric medications in the Spanish-interviewed group was not explained by the independent variables, whereas the difference in the use of antibiotics was. CONCLUSIONS: There are differences between Hispanic children according to acculturation, and acculturation affects prescription medication use. These findings may be used to address more specifically the needs of Hispanic children, particularly mental health needs.
