Objective: To evaluate the association between adverse childhood experiences (ACEs) and chronic pain during childhood and adolescence. Methods: Cross-sectional analysis of the 2016-2017 National Survey of Children's Health, including 48,567 child participants of 6 to 17 years of age. Parents of children reported on 9 ACEs. Chronic pain was defined as parents reporting that their children had “frequent or chronic difficulty with repeated or chronic physical pain, including headache or other back or body pain during the past 12 months.” Multivariate logistic regression analysis adjusted for sociodemographic and health-related factors. Results: In this nationally representative sample, 49.8% of children were exposed to one or more ACEs during their lifetime. Children with exposure to 1 or more ACEs had higher rates of chronic pain (8.7%) as compared to those with no reported ACEs (4.8%). In multivariate analysis, children with ACEs had increased odds for chronic pain (adjusted odds ratio [aOR]: 1.6, 95% confidence interval [CI]: 1.3–2.2, for 0 vs 1 ACE and aOR: 2.7, 95% CI: 2.1–3.4 for 0 vs 4+ ACEs). The strongest associations of individually measured ACEs with chronic pain included financial instability (aOR: 1.9, 95% CI: 1.6–2.2), living with a mentally ill adult (aOR: 1.8, 95% CI: 1.5–2.2), and having experienced discrimination based on race (aOR: 1.7, 95% CI: 1.3–2.2). Conclusions: Children and adolescents with ACEs had increased risk for chronic pain, and this association increased in a dose-dependent fashion.

The primary objective of this study was to assess the impact of pediatric pain-related conditions on health care expenditures. We analyzed data from a nationally representative sample of 6- to 17-year-old children captured in the 2007 National Health Interview Survey and 2008 Medical Expenditure Panel Survey. Health care expenditures of children with pain-related conditions were compared with those of children without pain-related conditions. Pain-related conditions were associated with incremental health care expenditures of $1339 (95% confidence interval [CI], $248-$2447) per capita. Extrapolated to the nation, pediatric pain-related conditions were associated with $11.8 billion (95% CI, $2.18-$21.5 billion) in total incremental health care expenditures. The incremental health care expenditures associated with pediatric pain-related conditions were similar to those of attention deficit and hyperactivity disorder ($9.23 billion; 95% CI, $1.89-$18.1 billion), but more than those associated with asthma ($5.35 billion; 95% CI, $0-$12.3 billion) and obesity ($0.73 billion; 95% CI, $6.28-$8.81 billion). Health care expenditures for pediatric pain-related conditions exert a considerable economic burden on society. Efforts to prevent and treat pediatric pain-related conditions are urgently needed.

Prescription opioid misuse is a major public health concern in the United States, yet little is known about national prescription patterns. We aimed to assess trends in opioid prescriptions made to children and adolescents, to their families, and to adults in the United States from 1996 to 2012. The sample was drawn from nationally representative data, the Medical Expenditure Panel Surveys. We used survey design methods to examine trends in prescription opioid use over time and a logistic regression analysis to examine predictors associated with opioid use. Findings indicated that from 1996 to 2012 opioid prescriptions to children and adolescents remained stable and low. In 1996, 2.68% of children received an opioid prescription, and in 2012, 2.91% received an opioid prescription. In contrast, opioid prescriptions to family members of children and adolescents and adults in general significantly increased during this period. The most common opioid prescriptions to children and adolescents in 2012 were codeine, hydrocodone, and oxycodone. Using multivariate logistic regression models, the white non-Hispanic race, older age, health insurance, and parent-reported fair to poor general health were associated with higher rates of opioid prescriptions in children and adolescents. Our main finding was that although the rates of opioid prescriptions have increased among adults in the United States, the rates have not changed among children and adolescents. Recent epidemiologic association studies have identified a strong link between increased opioid prescriptions and increased rates of opioid misuse and abuse in adults. Future studies should assess the association between adult opioid prescriptions and children or adolescent opioid misuse.

Racial differences exist in analgesic prescribing for children during emergency department and ambulatory surgery visits in the United States; however, it is unknown whether this is true in the outpatient setting. We examined racial and ethnic differences in outpatient analgesic prescribing using nationally representative data from 113,929 children from the Medical Expenditure Panel Survey. We also examined whether patient–provider race and ethnic concordance was associated with opioid prescription. White children were more commonly prescribed opioids as compared to minorities (3.0% vs 0.9%-1.7%), except for Native American children who had similar rates of opioid prescription (2.6%) as white children. Minorities were more likely to receive nonopioid analgesics than white children (2.0%-5.7% vs 1.3%). Although most white children had race-concordant providers (93.5%), only 34.3% of black children and 42.7% of Hispanic children had race-concordant providers. Among black children, having a race concordant usual source of care provider was associated with a decreased likelihood of receiving an opioid prescription as compared to having a white usual source of care provider (adjusted odds ratio [95% confidence interval] = 0.51 [0.30-0.87]). For all other racial groups, patient–provider race-concordance was not associated with likelihood of opioid prescription. Racial differences exist in analgesic prescriptions to children at outpatient health care visits in the United States, with white children more likely to receive opioids and minorities more likely to receive nonopioid analgesics. Health care providers' race and ethnicity may play a significant role in extant analgesic differences. Further work should focus on understanding the role of provider race and ethnicity in analgesic differences to children in the United States.
