Heterogeneous definitions used for picky eating led to a wide range of reported prevalence and an unclear relationship with weight. Consistent definitions and an improved understanding of such a relationship could help clinicians provide appropriate anticipatory guidance.

ImportanceDepression, suicidal ideation, and self-harm behaviors in youth are associated with functional impairment and suicide.ObjectiveTo review the evidence on screening for depression or suicide risk in children and adolescents to inform the US Preventive Services Task Force (USPSTF).Data SourcesPubMed, Cochrane Library, PsycINFO, CINAHL, and trial registries through July 19, 2021; references, experts, and surveillance through June 1, 2022.Study SelectionEnglish-language, randomized clinical trials (RCTs) of screening for depression or suicide risk; diagnostic test accuracy studies; RCTs of psychotherapy and first-line pharmacotherapy; RCTs, observational studies, and systematic reviews reporting harms.Data Extraction and SynthesisTwo reviewers assessed titles/abstracts, full-text articles, and study quality and extracted data; when at least 3 similar studies were available, meta-analyses were conducted.Main Outcomes and MeasuresTest accuracy, symptoms, response, remission, loss of diagnosis, mortality, functioning, suicide-related events, and adverse events.ResultsTwenty-one studies (N = 5433) were included for depression and 19 studies (N = 6290) for suicide risk. For depression, no studies reported on the direct effects of screening on health outcomes, and 7 studies (n = 3281) reported sensitivity of screening instruments ranging from 0.59 to 0.94 and specificity from 0.38 to 0.96. Depression treatment with psychotherapy was associated with improved symptoms (Beck Depression Inventory pooled standardized mean difference, −0.58 [95% CI, −0.83 to −0.34]; n = 471; 4 studies; and Hamilton Depression Scale pooled mean difference, −2.25 [95% CI, −4.09 to −0.41]; n = 262; 3 studies) clinical response (3 studies with statistically significant results using varying thresholds), and loss of diagnosis (relative risk, 1.73 [95% CI, 1.00 to 3.00; n = 395; 4 studies). Pharmacotherapy was associated with improvement on symptoms (Children’s Depression Rating Scale–Revised mean difference, −3.76 [95% CI, −5.95 to −1.57; n = 793; 3 studies), remission (relative risk, 1.20 [95% CI, 1.00 to 1.45]; n = 793; 3 studies) and functioning (Children’s Global Assessment Scale pooled mean difference, 2.60 (95% CI, 0.78 to 4.42; n = 793; 3 studies). Other outcomes were not statistically significantly different. Differences in suicide-related outcomes and adverse events for pharmacotherapy when compared with placebo were not statistically significant. For suicide risk, no studies reported on the direct benefits of screening on health outcomes, and 2 RCTs (n = 2675) reported no harms of screening. One study (n = 581) reported on sensitivity of screening, ranging from 0.87 to 0.91; specificity was 0.60. Sixteen RCTs (n = 3034) reported on suicide risk interventions. Interventions were associated with lower scores for the Beck Hopelessness Scale (pooled mean difference, −2.35 [95% CI, −4.06 to −0.65]; n = 644; 4 RCTs). Findings for other suicide-related outcomes were mixed or not statistically significantly different.Conclusion and RelevanceIndirect evidence suggested that some screening instruments were reasonably accurate for detecting depression. Psychotherapy and pharmacotherapy were associated with some benefits and no statistically significant harms for depression, but the evidence was limited for suicide risk screening instruments and interventions.

ImportanceAnxiety in children and adolescents is associated with impaired functioning, educational underachievement, and future mental health conditions.ObjectiveTo review the evidence on screening for anxiety in children and adolescents to inform the US Preventive Services Task Force.Data SourcesPubMed, Cochrane Library, PsycINFO, CINAHL, and trial registries through July 19, 2021; references, experts, and surveillance through June 1, 2022.Study SelectionEnglish-language, randomized clinical trials (RCTs) of screening; diagnostic test accuracy studies; RCTs of cognitive behavioral therapy (CBT) or US Food and Drug Administration–approved pharmacotherapy; RCTs, observational studies, and systematic reviews reporting harms.Data Extraction and SynthesisTwo reviewers assessed titles/abstracts, full-text articles, and study quality and extracted data; when at least 3 similar studies were available, meta-analyses were conducted.Main Outcomes and MeasuresTest accuracy, symptoms, response, remission, loss of diagnosis, all-cause mortality, functioning, suicide-related symptoms or events, adverse events.ResultsThirty-nine studies (N = 6065) were included. No study reported on the direct benefits or harms of screening on health outcomes. Ten studies (n = 3260) reported the sensitivity of screening instruments, ranging from 0.34 to 1.00, with specificity ranging from 0.47 to 0.99. Twenty-nine RCTs (n = 2805) reported on treatment: 22 on CBT, 6 on pharmacotherapy, and 1 on CBT, sertraline, and CBT plus sertraline. CBT was associated with gains on several pooled measures of symptom improvement (magnitude of change varied by outcome measure), response (pooled relative risk [RR], 1.89 [95% CI, 1.17 to 3.05]; n = 606; 6 studies), remission (RR, 2.68 [95% CI, 1.48 to 4.88]; n = 321; 4 studies), and loss of diagnosis (RR range, 3.02-3.09) when compared with usual care or wait-list controls. The evidence on functioning for CBT was mixed. Pharmacotherapy, when compared with placebo, was associated with gains on 2 pooled measures of symptom improvement—mean difference (Pediatric Anxiety Rating Scale mean difference, −4.0 [95% CI, −5.5 to −2.5]; n = 726; 5 studies; and Clinical Global Impression–Severity scale mean difference, −0.84 [95% CI, −1.13 to −0.55]; n = 550; 4 studies) and response (RR, 2.11 [95% CI, 1.58 to 2.98]; n = 370; 5 studies)—but was mixed on measures of functioning. Eleven RCTs (n = 1293) reported harms of anxiety treatments. Suicide-related harms were rare, and the differences were not statistically significantly different.Conclusions and RelevanceIndirect evidence suggested that some screening instruments were reasonably accurate. CBT and pharmacotherapy were associated with benefits; no statistically significant association with harms was reported.

Clinical practice guidelines are evidence-based recommendations with the potential to improve population health, yet they remain inconsistently utilized. In this commentary we discuss barriers and drivers to implementing clinical practice guidelines. We also suggest ways to support their translation into practice.
