Purpose-Early pubertal maturation has been linked to higher rates of aggressive and delinquent behaviors among white, middle class females. Less is known about this association for males, minorities, or among adolescents from urban communities. The aim of this paper is to evaluate underlying mechanisms of the association between early pubertal timing and both aggression and delinquency among a sample of minority, males and females from an urban community.Methods-The association between perceived early pubertal maturation and aggressive or delinquent behaviors for African American and Latino males and females (n = 1366) was examined as well as pathways between early maturation and these negative outcomes longitudinally across 6 th , 7 th , and 8 th grades.Results-Early maturers reported higher mean levels of both aggression and delinquency at all time points regardless of gender or ethnicity. Associating with delinquent peers in 6 th grade fully mediated the association between early maturation and both aggression and delinquency at all time points. Early maturers did not differentially associate with greater numbers of delinquent peers in either 7 th or 8 th grade.Conclusions-These results provide valuable information regarding at-risk groups and inform future intervention efforts.Both aggression and delinquency escalate during middle school (i.e., 6 th -8 th grade, approximately ages 11-14) and peak at age 16 for both males and females [1][2][3].

BackgroundThere is currently conflicting evidence surrounding the effects of obesity on postoperative outcomes. Previous studies have found obesity to be associated with adverse events, but others have found no association. The aim of this study was to determine whether increasing body mass index (BMI) is an independent risk factor for development of major postoperative complications.MethodsThis was a multicentre prospective cohort study across the UK and Republic of Ireland. Consecutive patients undergoing elective or emergency gastrointestinal surgery over a 4‐month interval (October–December 2014) were eligible for inclusion. The primary outcome was the 30‐day major complication rate (Clavien–Dindo grade III–V). BMI was grouped according to the World Health Organization classification. Multilevel logistic regression models were used to adjust for patient, operative and hospital‐level effects, creating odds ratios (ORs) and 95 per cent confidence intervals (c.i.).ResultsOf 7965 patients, 2545 (32·0 per cent) were of normal weight, 2673 (33·6 per cent) were overweight and 2747 (34·5 per cent) were obese. Overall, 4925 (61·8 per cent) underwent elective and 3038 (38·1 per cent) emergency operations. The 30‐day major complication rate was 11·4 per cent (908 of 7965). In adjusted models, a significant interaction was found between BMI and diagnosis, with an association seen between BMI and major complications for patients with malignancy (overweight: OR 1·59, 95 per cent c.i. 1·12 to 2·29, P = 0·008; obese: OR 1·91, 1·31 to 2·83, P = 0·002; compared with normal weight) but not benign disease (overweight: OR 0·89, 0·71 to 1·12, P = 0·329; obese: OR 0·84, 0·66 to 1·06, P = 0·147).ConclusionOverweight and obese patients undergoing surgery for gastrointestinal malignancy are at increased risk of major postoperative complications compared with those of normal weight.

ObjectiveTo assess the variation in body dissatisfaction and depressive symptoms by weight status and the bi-directional relations between body dissatisfaction and depressive symptoms by weight status among Black adolescents. MethodsA sample of 153 Black adolescents aged 12-13 years, either overweight/obese (n = 57, 37%) or healthy weight (n = 96, 63%), were recruited and evaluated three times over two years (T1, T2 and T3). Measured weight and height were converted to age and sex-specific BMI z-score; body dissatisfaction was measured with silhouettes, and depressive symptoms were measured with the Beck Depression Inventory (BDI-I). Bidirectional relations were assessed with cross-lagged panel analyses, accounting for stability over time and contemporary correlations. ResultsBody dissatisfaction was higher among the overweight/obese group than the healthy weight group. No significant differences were found for depressive symptoms by weight status. Among the overweight/obese group, there were bidirectional relations: antecedent body dissatisfaction predicted subsequent depressive symptoms (T1-T2: β = 0.42, SE = 0.11, p<0.001; T2-T3: β = 0.36, SE = 0.09, p<0.001) and antecedent depressive symptoms predicted subsequent body dissatisfaction (T1-T2: β = 0.25, SE = 0.10, p = 0.012; T2-T3: β = 0.17, SE = 0.08, p = 0.045). Among the healthy weight group, there was no relation in either direction.

IMPORTANCE Corporal punishment is a leading risk factor for physical abuse. Strong anecdotal evidence from physicians and other professionals working in child protection suggest that punishment-initiated physical abuse for school-aged children increases after release of report cards. However, no empirical examination of this association has occurred. OBJECTIVE To examine the temporal association between school report card release and incidence rates (IRs) of physical abuse. DESIGN, SETTING, AND PARTICIPANTS This retrospective study reviewed calls to a state child abuse hotline and school report card release dates across a single academic year in Florida. Data were collected in a 265-day window from September 8, 2015, to May 30, 2016, in the 64 of 67 Florida counties with report card release dates available (16 960 days). Participants included all children aged 5 to 11 years for whom calls were made. A total of 1943 verified cases of physical abuse were reported in the study period in the 64 counties. Data were analyzed from October 2017 through May 2018. EXPOSURES School report cards release across a single academic year, measured daily by county. MAIN OUTCOMES AND MEASURES Daily counts of calls to a child abuse hotline that later resulted in agency-verified incidents of child physical abuse across a single academic year by county. RESULTS During the academic year, 167 906 calls came in to the child abuse hotline for children aged 5 to 11 years; 17.8% (n = 29 887) of these calls were suspected incidents of physical abuse, and 2017 (6.7%) of these suspected incidents were later verified as cases of physical abuse before excluding the 3 counties with no release dates available. Among the 1943 cases included in the analysis (58.9% males [n = 1145]; mean [SD] age, 7.69 [1.92] years), calls resulting in verified reports of child physical abuse occurred at a higher rate on Saturdays after a Friday report card release compared with Saturdays that do not follow a Friday report card release (IR ratio, 3.75; 95% CI, 1.21-11.63; P = .02). No significant association of report card release with IRs was found for any other days of the week. CONCLUSION AND RELEVANCE This association of school report card release and physical abuse appears to illustrate a unique systems-based opportunity for prevention.
