Effectiveness of Educational Materials Designed to Change Knowledge and Behaviors Regarding Crying and Shaken-Baby Syndrome in Mothers of Newborns: A Randomized, Controlled Trial

BACKGROUND. Infant crying is an important precipitant for shaken-infant syndrome. OBJECTIVE. To determine if parent education materials (The Period of PURPLE Crying [PURPLE]) change maternal knowledge and behavior relevant to infant shaking. METHODS. This study was a randomized, controlled trial conducted in prenatal classes, maternity wards, and pediatric practices. There were 1374 mothers of newborns randomly assigned to the PURPLE intervention and 1364 mothers to the control group. Primary outcomes were measured by telephone 2 months after delivery. These included 2 knowledge scales about crying and the dangers of shaking; 3 scales about behavioral responses to crying generally and to unsoothable crying, and caregiver self-talk in response to unsoothable crying; and 3 questions concerning the behaviors of sharing of information with others about crying, walking away if frustrated, and the dangers of shaking. RESULTS. The mean infant crying knowledge score was greater in the intervention group (69.5) compared with controls (63.3). Mean shaking knowledge was greater for intervention subjects (84.8) compared with controls (83.5). For reported maternal behavioral responses to crying generally, responses to unsoothable crying, and for self-talk responses, mean scores for intervention mothers were similar to those for controls. For the behaviors of information sharing, more intervention mothers reported sharing information about walking away if frustrated and the dangers of shaking, but there was little difference in sharing information about infant crying. Intervention mothers also reported increased infant distress. CONCLUSIONS. Use of the PURPLE education materials seem to lead to higher scores in knowledge about early infant crying and the dangers of shaking, and in sharing of information behaviors considered to be important for the prevention of shaking.

Inconsolable Infant Crying and Maternal Postpartum Depressive Symptoms

OBJECTIVE: To quantify the extent to which maternal report of inconsolable infant crying, rather than colic (defined by Wessel’s criteria of daily duration of fussing and crying >3 hours), is associated with maternal postpartum depressive symptoms. METHODS: Participants were 587 mothers who were recruited shortly before or after delivery and followed longitudinally. At 5 to 6 weeks postpartum, mothers recorded the duration and mode (fussing, crying, or inconsolable crying) of their infant’s distress by using the Baby’s Day Diary. The Edinburgh Postnatal Depression Scale (EPDS) was administered at enrollment and at 8 weeks postpartum. Using regression models that included baseline EPDS scores and multiple confounders, we examined associations of colic and inconsolable crying with later maternal EPDS scores at 8 weeks postpartum. RESULTS: Sixty mothers (10%) met the EPDS threshold for “possible depression” (score ≥9) at 8 weeks postpartum. For mothers reporting >20 minutes of inconsolable crying per day, the adjusted odds ratio for an EPDS score ≥9 was 4.0 (95% confidence interval: 2.0–8.1), whereas the adjusted odds ratio for possible depression in mothers whose infants had colic was 2.0 (95% confidence interval: 1.1–3.7). These associations persisted after adjusting for baseline depression symptoms. CONCLUSIONS: Maternal report of inconsolable infant crying may have a stronger association with postpartum depressive symptoms than infant colic. Asking a mother about her ability to soothe her infant may be more relevant for potential intervention than questions about crying and fussing duration alone.

Infant Distress at Five Weeks of Age and Caregiver Frustration

OBJECTIVE To investigate the differential association of three modes (fussing, crying, unsoothable crying) and three properties (duration/day, frequency/day, maximum bout length) of infant distress with daily caregiver frustration. STUDY DESIGN Replicated cross-sectional studies were completed in Vancouver, British Columbia (n = 1065) and Seattle, Washington (n = 1857). Infant fussing, crying, and unsoothable crying and caregiver frustration were measured daily for 4 days at 5 weeks of age by the Babys Day Diary. Generalized estimating equation models were used to predict caregiver frustration from nine measurements of distress. RESULTS In Vancouver, measurements of distress significantly associated with caregiver frustration in decreasing order of magnitude were as follow: (1) maximum bout length of unsoothable crying; (2) duration/day of crying; and (3) frequency of unsoothable crying and duration/day of fussing. In Seattle, associated measurements of distress were: (1) maximum bout length of unsoothable crying; (2) maximum bout length and duration/day of crying, frequency of unsoothable crying, and duration/day of fussing; and (3) frequency/day of crying. CONCLUSIONS Daily caregiver frustration is associated differentially with different modes and properties of infant distress. Specifically, maximum bout length of unsoothable crying was most strongly related in both sites. Additionally, frequency/day of unsoothable crying and duration/day of crying and of fussing were significantly associated at both sites.

The Medical Cost of Abusive Head Trauma in the United States

OBJECTIVES: Health consequences of shaken baby syndrome, or pediatric abusive head trauma (AHT), can be severe and long-lasting. We aimed to estimate the multiyear medical cost attributable to AHT. METHODS: Using Truven Health MarketScan data, 2003–2011, we identified children 0 to 4 years old with commercial or Medicaid insurance and AHT diagnoses. We used exact case–control matching based on demographic and insurance characteristics such as age and health plan type to compare medical care between patients with and without AHT diagnoses. Using regression models, we assessed service use (ie, average annual number of inpatient visits per patient) and inpatient, outpatient (including emergency department), drug, and total medical costs attributable to an AHT diagnosis during the 4-year period after AHT diagnosis. RESULTS: We assessed 1209 patients with AHT and 5895 matched controls. Approximately 48% of patients with AHT received inpatient care within 2 days of initial diagnosis, and 25% were treated in emergency departments. AHT diagnosis was associated with significantly greater medical service use and higher inpatient, outpatient, drug, and total costs for multiple years after the diagnosis. The estimated total medical cost attributable to AHT in the 4 years after diagnosis was
