Improving Substance Use Prevention, Assessment, and Treatment Financing to Enhance Equity and Improve Outcomes Among Children, Adolescents, and Young Adults.

Access to timely prevention and treatment services remains challenging for many children, adolescents, young adults, and families affected by substance use. The American Academy of Pediatrics recognizes the scope and urgency of this problem and has developed this policy statement for consideration by Congress, federal and state policy makers, and public and private payers. This policy statement updates the 2001 policy statement "Improving Substance Abuse Prevention, Assessment, and Treatment Financing for Children and Adolescents" and provides recommendations for financing substance use prevention, assessment, and treatment of children, adolescents, and young adults.

The impact of reducing the frequency of night feeding on infant BMI.

BACKGROUND: Teaching caregivers to respond to normal infant night awakenings in ways other than feeding is a common obesity prevention effort. Models can simulate caregiver feeding behavior while controlling for variables that are difficult to manipulate or measure in real life. METHODS: We developed a virtual infant model representing an infant with an embedded metabolism and his/her daily sleep, awakenings, and feeds from their caregiver each day as the infant aged from 6 to 12 months (recommended age to introduce solids). We then simulated different night feeding interventions and their impact on infant body mass index (BMI). RESULTS: Reducing the likelihood of feeding during normal night wakings from 79% to 50% to 10% lowered infant BMI from the 84th to the 75th to the 62nd percentile by 12 months, respectively, among caregivers who did not adaptively feed (e.g., adjust portion sizes of solid foods with infant growth). Among caregivers who adaptively feed, all scenarios resulted in relatively stable BMI percentiles, and progressively reducing feeding probability by 10% each month showed the least fluctuations. CONCLUSIONS: Reducing night feeding has the potential to impact infant BMI, (e.g., 10% lower probability can reduce BMI by 20 percentile points) especially among caregivers who do not adaptively feed. IMPACT: Teaching caregivers to respond to infant night waking with other soothing behaviors besides feeding has the potential to reduce infant BMI. When reducing the likelihood of feeding during night wakings from 79% to 50% to 10%, infants dropped from the 84th BMI percentile to the 75th to the 62nd by 12 months, respectively, among caregivers who do not adaptively feed. Night-feeding interventions have a greater impact when caregivers do not adaptively feed their infant based on their growth compared to caregivers who do adaptively feed. Night-feeding interventions should be one of the several tools in a multi-component intervention for childhood obesity prevention.

Can following formula-feeding recommendations still result in infants who are overweight or have obesity?

BACKGROUND: Studies show that by 3 months, over half of US infants receive formula, and guidelines play a key role in formula feeding. The question then is, what might happen if caregivers follow guidelines and, more specifically, are there situations where following guidelines can result in infants who are overweight/have obesity? METHODS: We used our "Virtual Infant" agent-based model representing infant-caregiver pairs that allowed caregivers to feed infants each day according to guidelines put forth by Johns Hopkins Medicine (JHM), Children's Hospital of Philadelphia (CHOP), Children's Hospital of the King's Daughters (CHKD), and Women, Infants, and Children (WIC). The model simulated the resulting development of the infants from birth to 6 months. The two sets of guidelines vary in their recommendations, and do not provide studies that support amounts at given ages. RESULTS: Simulations identified several scenarios where caregivers followed JHM/CHOP/CHKD and WIC guidelines, but infants still became overweight/with obesity by 6 months. For JHM/CHOP/CHKD guidelines, this occurred even when caregivers adjusted feeding based on infant's weight. For WIC guidelines, when caregivers adjusted formula amounts, infants maintained healthy weight. CONCLUSIONS: WIC guidelines may be a good starting point for caregivers who adjust as their infant grows, but the minimum amounts for JHM/CHKD/CHOP recommendations may be too high. IMPACT: Our virtual infant simulation study answers the question: can caregivers follow current formula-feeding guidelines and still end up with an infant who is overweight or has obesity? Our study identified several situations in which unhealthy weight gain and/or weight loss could result from following established formula-feeding recommendations. Our study also suggests that the minimum recommended amount of daily formula feeding should be lower for JHM/CHOP/CHKD guidelines to give caregivers more flexibility in adjusting daily feeding levels in response to infant weight. WIC guidelines may be a good starting point for caregivers who adjust as their infant grows. In order to understand how to adjust guidelines, we can use computational simulation models, which serve as "virtual laboratories" to help overcome the logistical and ethical issues of clinical trials.

The Impact of Following Solid Food Feeding Guides on BMI Among Infants: A Simulation Study.

INTRODUCTION: There are several recommendations advising caregivers when and how to introduce solid food to infants. These complementary feeding guides vary in terms of the recommendations for timing and portions. The objective of this study is to determine the impact of following different guidelines on weight trajectories of infants. METHODS: In 2018, the study team developed a computational simulation model to capture feeding behaviors, activity levels, metabolism, and body size of infants from 6 months to 1 year. Daily food intake of virtual infants based on feeding recommendations translated to changes in body weight. Next, simulations tested the impact of the following complementary feeding recommendations that provided amount, type, and timing of foods: Children's Hospital of Philadelphia, Johns Hopkins Medicine, Enfamil, and Similac. RESULTS: When virtual caregivers fed infants according to the four different guides, none of the simulated situations resulted in normal weight at 12 months when infants were also being breastfed along average observed patterns. Reducing breast milk portions in half while caregivers fed infants according to complementary feeding guidelines resulted in overweight BMIs between 9 and 11 months for Children's Hospital of Philadelphia, Johns Hopkins Medicine, and Enfamil guidelines. Cutting breast milk portions in half also led to infants reaching unhealthy underweight BMI percentiles between 7 and 11 months for female and male infants when caregivers followed Children's Hospital of Philadelphia, Johns Hopkins Medicine, and Similac guidelines. CONCLUSIONS: This study identified situations in which infants could reach unhealthy weights, even while following complementary feeding guidelines, suggesting that current recommended portion sizes should be tightened.

Improving healthy eating in families with a toddler at risk for overweight: a cluster randomized controlled trial.

OBJECTIVE: To ascertain whether a parent education program based on Satter's division of responsibility in feeding children (DOR) is effective in enhancing parent/child feeding interactions for children with an overweight/obese parent. The primary hypothesis was that the intervention would decrease parental pressure to eat. METHODS: Sixty-two families with a child between 2 and 4 years with at least 1 overweight/obese parent were randomly allocated using a cluster design to either the DOR intervention or a control group. The control group focused on increasing family consumption of healthy foods and activity levels and enhancing child sleep duration. The primary outcome was parent pressure on their child to eat. RESULTS: The DOR intervention was superior to the control group in reducing the pressure to eat. Two moderators of pressure to eat were found: disinhibition of eating and hunger. The parents in the DOR group, irrespective of disinhibition levels, lowered the pressure to eat, whereas those in the control group with low disinhibition increased the pressure to eat. There were similar findings for hunger. Gender moderated restrictive feeding with DOR parents lowering restriction more than parents of the control group in girls only. CONCLUSION: The DOR intervention was more effective in reducing the parent pressure to eat and food restriction (in girls only) than the control group.

Increasing immunization coverage.

In 1977, the American Academy of Pediatrics issued a statement calling for universal immunization of all children for whom vaccines are not contraindicated. In 1995, the policy statement "Implementation of the Immunization Policy" was published by the American Academy of Pediatrics, followed in 2003 with publication of the first version of this statement, "Increasing Immunization Coverage." Since 2003, there have continued to be improvements in immunization coverage, with progress toward meeting the goals set forth in Healthy People 2010. Data from the 2007 National Immunization Survey showed that 90% of children 19 to 35 months of age have received recommended doses of each of the following vaccines: inactivated poliovirus (IPV), measles-mumps-rubella (MMR), varicella-zoster virus (VZB), hepatitis B virus (HBV), and Haemophilus influenzae type b (Hib). For diphtheria and tetanus and acellular pertussis (DTaP) vaccine, 84.5% have received the recommended 4 doses by 35 months of age. Nevertheless, the Healthy People 2010 goal of at least 80% coverage for the full series (at least 4 doses of DTaP, 3 doses of IPV, 1 dose of MMR, 3 doses of Hib, 3 doses of HBV, and 1 dose of varicella-zoster virus vaccine) has not yet been met, and immunization coverage of adolescents continues to lag behind the goals set forth in Healthy People 2010. Despite these encouraging data, a vast number of new challenges that threaten continued success toward the goal of universal immunization coverage have emerged. These challenges include an increase in new vaccines and new vaccine combinations as well as a significant number of vaccines currently under development; a dramatic increase in the acquisition cost of vaccines, coupled with a lack of adequate payment to practitioners to buy and administer vaccines; unanticipated manufacturing and delivery problems that have caused significant shortages of various vaccine products; and the rise of a public antivaccination movement that uses the Internet as well as standard media outlets to advance a position, wholly unsupported by any scientific evidence, linking vaccines with various childhood conditions, particularly autism. Much remains to be accomplished by physician organizations; vaccine manufacturers; third-party payers; the media; and local, state, and federal governments to ensure dependable vaccine supply and payments that are sufficient to continue to provide immunizations in public and private settings and to promote effective strategies to combat unjustified misstatements by the antivaccination movement. Pediatricians should work individually and collectively at the local, state, and national levels to ensure that all children without a valid contraindication receive all childhood immunizations on time. Pediatricians and pediatric organizations, in conjunction with government agencies such as the Centers for Disease Control and Prevention, must communicate effectively with parents to maximize their understanding of the overall safety and efficacy of vaccines. Most parents and children have not experienced many of the vaccine-preventable diseases, and the general public is not well informed about the risks and sequelae of these conditions. A number of recommendations are included for pediatricians, individually and collectively, to support further progress toward the goal of universal immunization coverage of all children for whom vaccines are not contraindicated.

Puberty and gender interact to predict social anxiety symptoms in early adolescence.

This study examines direct and interactive effects of puberty and gender on social anxiety symptoms in early adolescence. One hundred-six participants were assessed at ages 9.5 and 11 years. Results suggest that gender and puberty interact to predict social anxiety symptoms. Advanced puberty was associated with increased symptoms for girls only.

Childhood risk factors for thin body preoccupation and social pressure to be thin.

OBJECTIVE: Thin body preoccupation and social pressure to be thin (TBPSP) in adolescence are risk factors for the development of full and partial bulimia nervosa and binge eating disorder. This study examined precursors of these potent risk factors. METHOD: A prospective study followed 134 children from birth to 11.0 years and their parents. Recruitment began in January 1990 and ended in March 1991. The study was completed in December 2002. RESULTS: Two moderators identified different groups at risk for the development of TBPSP. A father with high body dissatisfaction characterized the largest group in which TBPSP was elevated for girls who were concerned about and attempted to modify their weight and for children with fathers who had a high drive for thinness. A child at risk for overweight characterized the second smaller group. Parental behaviors such as overcontrol of their child's eating, together with later pressure from parents and peers to be thin, were related to higher levels of TBPSP. CONCLUSIONS: Different pathways lead to the development of eating disorder psychopathology. These results suggest that prevention programs for eating disorders should begin in early childhood, possibly involving parental education and behavior change, and that different prevention programs may be required for different pathways.

Methamphetamine use following bariatric surgery in an adolescent.

Bariatric surgery is increasingly popular as a therapeutic strategy for morbidly obese adolescents. Adolescence represents a sensitive period of psychosocial development, and children with considerable weight loss may experience greater peer acceptance, accompanied by both positive and negative influences. Substance abuse exists as one of these negative influences. We present the case of an adolescent bariatric surgical patient who abused methamphetamines in the postoperative period, with consequent nutritional instability. A concerted effort must be made in the preoperative assessment of adolescent bariatric patients to delineate a history of illicit drug use, including abuse of diet pills and stimulants. Excessive postoperative weight loss or micronutrient supplementation non-compliance should raise a suspicion of stimulant use and appropriate screening tests should be performed. The consequent appetite suppression may manifest with signs of malnutrition such as bradycardia, hypotension, and weakness. Inpatient nutritional rehabilitation and psychiatric assessment should be considered.

The relationship between parental factors at infancy and parent-reported control over children's eating at age 7.

The objective of this study was to determine predictors of parental control over children's eating. Data were obtained from 135 children and their parents from the Stanford Infant Growth Study. Assessments were obtained from parents at their child's birth and age 7. Parental body dissatisfaction at their child's birth predicted pressure to eat for both sons and daughters. In addition, minority status, parent being born outside of the United States, and a mother's early return to work predicted parental pressure to eat for sons. For daughters, an early maternal pushy feeding style also predicted parental pressure to eat. Parental hunger, a parental history of eating disorders and parent being born outside of the United States predicted food restriction for daughters. There were no predictors of food restriction for sons. We concluded that parental control appears not always to be simply a reaction to a child's lack of self-control or overweight, but may be present before such issues arise, particularly with the presence of certain cultural factors.

Risk factors for childhood overweight: a prospective study from birth to 9.5 years.

OBJECTIVES: To ascertain risk factors for the development of overweight in children at 9.5 years of age. STUDY DESIGN: This was a prospective study of 150 children from birth to 9.5 years of age, with assessment of multiple hypothesized risk factors drawn from research reports. RESULTS: Five independent risk factors for childhood overweight were found. The strongest was parent overweight, which was mediated by child temperament. The remaining risk factors were low parent concerns about their child's thinness, persistent child tantrums over food, and less sleep time in childhood. Possible mechanisms by which each of these factors influence weight gain are outlined. Two different pathways to childhood overweight/obesity were found, depending on degree of parental overweight. CONCLUSIONS: There is evidence of considerable interaction between parent and child characteristics in the development of overweight. Several of the identified risk factors are amenable to intervention possibly leading to the development of early prevention programs.

Bariatric surgery for severely overweight adolescents: concerns and recommendations.

As the prevalence of obesity and obesity-related disease among adolescents in the United States continues to increase, physicians are increasingly faced with the dilemma of determining the best treatment strategies for affected patients. This report offers an approach for the evaluation of adolescent patients' candidacy for bariatric surgery. In addition to anthropometric measurements and comorbidity assessments, a number of unique factors must be critically assessed among overweight youths. In an effort to reduce the risk of adverse medical and psychosocial outcomes and increase compliance and follow-up monitoring after bariatric surgery, principles of adolescent growth and development, the decisional capacity of the patient, family structure, and barriers to adherence must be considered. Consideration for bariatric surgery is generally warranted only when adolescents have experienced failure of 6 months of organized weight loss attempts and have met certain anthropometric, medical, and psychologic criteria. Adolescent candidates for bariatric surgery should be very severely obese (defined by the World Health Organization as a body mass index of > or =40), have attained a majority of skeletal maturity (generally > or =13 years of age for girls and > or =15 years of age for boys), and have comorbidities related to obesity that might be remedied with durable weight loss. Potential candidates for bariatric surgery should be referred to centers with multidisciplinary weight management teams that have expertise in meeting the unique needs of overweight adolescents. Surgery should be performed in institutions that are equipped to meet the tertiary care needs of severely obese patients and to collect long-term data on the clinical outcomes of these patients.

Behavioral validation, precursors, and concomitants of picky eating in childhood.

OBJECTIVES: To validate the concept of parent-reported picky eating using objective, laboratory-based measures and to identify both child and parental precursors and concomitants of picky eating. METHOD: One hundred thirty-five infants were monitored from birth to 5.5 years. Behavioral measures of picky eating were obtained from standardized feedings at ages 3.5 and 5.5 years in the laboratory and at home. Child precursors were measures of infant sucking behavior; parental precursors were disinhibition of eating, restrained eating, body dissatisfaction, and body mass index. Parentally reported attitudes and behaviors thought to be related to pickiness and parental concomitants were taken from the Stanford Feeding Questionnaire. Child Temperament was assessed by the Children's Behavior Questionnaire. RESULTS: Picky eaters ate fewer foods and were especially more likely to avoid vegetables. Picky girls decreased their caloric intake between ages 3.5 and 5.5, whereas all other children increased their caloric intake. None of the included parental precursors was significantly related to pickiness. Picky eaters demonstrated a different sucking pattern with fewer sucks per feeding session at weeks 2 and 4. Finally, picky children displayed more parent-reported negative affect than nonpicky children. CONCLUSIONS: Parentally reported picky eating is associated with a consistent pattern of inhibited and selective eating beginning in infancy.
