Objective: The purpose of this study was to estimate the prevalence and time trends in prescriptions methylphenidate, dexamphetamine, atomoxetine children adolescents, within three diagnostic groups: 1) autism spectrum disorder (ASD), 2) attention-deficit/hyperactivity (ADHD), 3) other psychiatric disorders. Methods: Data from six different national registers were used merged identify a cohort all adolescents born Denmark between 1990 2001 (n=852,711). Sociodemographic covariates on members...

Objective: The purpose of this study was to determine whether stimulant users are at higher risk a later cardiovascular event than non-users, examining association in both national cohort and population-based sample children adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD). We also aim examine possible dose-response relationship such an association. Methods: conducted longitudinal, prospective all born Denmark between 1990 1999. Within cohort, ADHD were identified....

Abstract Segregation of the labour market into a family‐friendly and non‐family‐friendly sector implies that women self‐select sectors depending on institutional constraints, preferences for working conditions expected wage differences. We take this dimension account find severe penalty after birth‐related leave in sector, so who would be affected by sector. The is combination large human‐capital depreciation effect, child no recovery.

This article uses register-based data to investigate the effects of school starting age on crime. Through this, we provide insights into determinants crime-age profiles. We exploit that Danish children typically start first grade in calendar year they turn seven, which gives rise a discontinuity for born around new year. Our analysis speaks against simple invariant profile as is popular criminology: find higher lowers propensity commit crime at young ages. also number crimes committed boys.

The aims were to describe first-time mothers' confidence, mood and stress 2 6 months postpartum investigate the extent which tools measuring maternal confidence used alone or together at predict postpartum.A cohort including 513 self-reported questionnaires concerning three scales: Karitane Parenting Confidence Scale (KPCS), Edinburgh Postnatal Depression (EPDS), Parental Stress (PSS) collected postpartum. Descriptive statistic, simple multiple linear regression analysis used.First-time with...

Abstract We estimate the effect of motherhood on wages using matching. distinguish between net and direct effects. The includes total wage costs, whereas represents causal effect. Since covariates are likely affected by motherhood, latter is not immediately uncovered. therefore implement two strategies: first, we confine analysis to consider sector‐specific treatment effects; second, impose additive separability outcome equation. find negative effects that vary little with sector. small in...

Bullying is a widespread social phenomenon that thought to have detrimental effects on life outcomes. This paper investigates the link between bullying and later school performance. We rely rich survey register-based data for children born in region of Denmark during 1990–92, which allows us carefully consider possible confounders including psychological factors. implement an IV strategy inspired by Carrell Hoekstra (2010) where we instrument victim status with proportion peers from troubled...

Summary We investigate price sensitivity of demand for prescription drugs, using drug purchase records the entire Danish population. identify responsiveness by exploiting variation in prices caused kinked reimbursement schemes and implement a regression kink design. The results suggest some with corresponding elasticities ranging from −0.2 to −0.7. Individuals chronic disease especially individuals above age 65 respond less drugs.

The purpose of this article was to examine whether injuries in early childhood and gender predict prescriptions stimulant medication three groups children: With attention-deficit/hyperactivity disorder (ADHD), autism spectrum (ASD), other psychiatric disorders (OPD).This a population-based study with prospective complete follow-up children ADHD (n=11,553), ASD (n=9698), OPD (n=48,468), whom 61%, 16%, 3%, respectively, were treated stimulants. For all 69,719 individual data on diagnoses,...

In this study, we use a policy reform that lowered the minimum age criminal responsibility from 15 14 years for 20-month period investigate whether lower limits prosecution conviction in legal system affect crime.

Using local variation between municipalities, I analyze the degree to which price of high-quality publicly subsidized childcare affects female employment following maternity leave. Importantly, prices are income dependent and thus likely endogenous, yet by exploiting information on minimum compensation during non-employment, bypass this problem. The results show that negatively employment. A increase €1 per month decreases 0.08%, corresponds a elasticity −0.17. These effects prevail first 12...
