Background: Iron deficiency anemia (IDA) affects 2%-5% of reproductive-age women. Screening is based on risk factors, such as a low-iron diet and menstruation. However, published IDA risk factors fail to consider agerelated risks specific to adolescent women, potentially limiting identification of high-risk adolescents for objective testing. The goal of the study was to examine IDA risk factors in a nationally representative sample of younger (12-21 years) and older (22-49 years) reproductive-age women. Materials and Methods: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2003-2010. IDA was defined using hemoglobin, ferritin, soluble transferrin receptor, standard NHANES laboratory measures. Sex-, age-, and race-specific hemoglobin values defined anemia. Iron deficiency was calculated using ferritin and soluble transferrin receptor in the body iron formula. Logistic regression assessed the association of potential risk factors (race, body mass index, poverty, iron intake, tobacco/nicotine exposure, physical activity, menses, and contraceptive use) with IDA in younger and older women. Results: The prevalence of IDA was 2.4% and 5.5% among younger and older women, respectively. Among younger women, contraceptive use was marginally protective from IDA (risk ratio 0.50, 95% confidence interval [CI] 0.25-1.00). Among older women, significant variables included Black race (risk ratio 2.31, 95% CI 1.33-4.02) and increased years menstruating ( ‡25 years vs. <25 years; risk ratio 1.93, 95% CI 0.99-3.76). Conclusions: Risk factors for IDA among older reproductive-age women do not apply to adolescent women. To better inform the timing and frequency of screening recommendations, further research must identify adolescent-specific IDA risk factors.

Urine dipstick is inexpensive, but it is a poor screening test for CKD and a cost-ineffective procedure for the primary care provider. These data support the change in the American Academy of Pediatrics guidelines on the use of screening dipstick urinalysis. Clinicians must consider the cost-effectiveness of preventive care procedures to make better use of available resources.

IMPORTANCEAdolescent major depressive disorder (MDD) prevalence has nearly doubled in the past decade. The US Preventive Services Task Force endorses universal adolescent MDD screening in primary care; however, most adolescents lack preventive health care, resulting in worsening disparities in MDD screening and treatment. OBJECTIVE To evaluate the effectiveness of universal adolescent MDD screening in the school setting in an effort to reduce disparities and improve MDD identification and treatment initiation. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial, conducted from November 6, 2018, to November 20, 2020, compared the usual school practice of targeted or selected screening based on observable behaviors of concern with universal MDD screening. Students within an identified school were randomized by grade to 1 of the 2 study groups. Study groups were compared using mixed-effects logistic regression. Participants included students in grades 9 through 12 enrolled at 1 of the 14 participating Pennsylvania public high schools.Author affiliations and article information are listed at the end of this article.

Objectives: To compare a protocol for pure-tone threshold testing, capable of detecting high-frequency hearing loss as indicated by notched audiometric configurations, with the current school rapid hearing screen and to determine typical adolescent noise exposures associated with notched audiometric configurations. Design: In conjunction with required school rapid hearing screening, a pure-tone threshold testing protocol was administered, specifically to test hearing at high frequencies. A single audiologist reviewed the results. Students completed a survey assessing their noise exposures. Setting: A public high school in Pennsylvania. Participants: Eleventh-grade students. Main Outcome Measure: Notched audiometric configurations on the pure-tone threshold test. Results: Among 296 participants, 78 (26.4%) failed puretone threshold testing compared with 15 (5.1%) failing rapid hearing screening. Among those failing the puretone threshold testing, 67 (85.9%) failed due to notched audiometric configurations. Self-reported headphone use with an MP3 player was significantly associated with notched audiometric configurations compared with use of earbuds or stereo connection/docking systems. Conclusions: Pure-tone threshold testing incorporating high frequencies detects adolescent hearing loss more often than rapid hearing screens. Most state hearing screens omit high-frequency testing, potentially missing high-frequency losses, such as noise-induced hearing loss. Because noise-induced hearing loss in particular is preventable and hazardous noise exposures have increased, a reliable school hearing screen to detect highfrequency hearing loss in adolescents is warranted.
