Generalized Linear Models (2nd ed.)

Every year, around 830 000 children die from unintentional or "accidental" injuries. The vast majority of these injuries occur in low-income and middle-income countries. However, dozens of prevention strategies and programmes exist. If they were integrated into other child survival programmes and implemented on a larger scale, many of these deaths and much of the injury-related disability could be prevented. Improved health services could also go a long way in reducing the consequences of these injuries.To draw attention to this important public health problem and the possible solutions, WHO and UNICEF have produced this World report on child injury prevention with support from many experts. The report documents the magnitude, risks and prevention measures for child injuries globally –particularly for drowning, burns, road traffic injuries, falls and poisoning. The report makes seven concrete recommendations for policy-makers to improve child injury prevention. This new document is an important policy and advocacy tool for raising attention the issue and guiding action around the world.

World Report on Child Injury Prevention

This book includes detailed information on many of the factors surrounding injuries--the man-made systems and products involved, the groups at greatest risk, and effective ways to protect people from injuries. The circumstances under which injuries occur, the etiologic agents, and the characteristics of the people involved are examined. Chapter 2 summarizes the importance of injuries in relation to other prominent health problems. Subsequent chapters describe injury mortality and, in cases where good population-based studies are available, nonfatal injuries. The analyses in Chapters 3-15 are primarily of injury deaths during 1977-1979, the most recent years for which detailed mortality data were available in mid-1983 for deaths other than those related to motor vehicles. Most of these data were collected by the U.S. Department of Health and Human Services, National Center for Health Statistics (NCHS). Chapters 16-20 summarize data on deaths from motor vehicle-related injuries. Most of these detailed data were obtained from the U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA). Data from the 1980 census provided denominators for the rates throughout the book, except for trendline calculations which were based on interpolations between census years. The purpose of this book is to improve understanding of the nature and magnitude of the injury problem in the United States. Although it includes some discussion of ameliorative approaches, there is no comprehensive coverage of injury research, theory, or prevention, since these have been comprehensively discussed elsewhere. This book is a thorough documentation of the injury problem. Most of the information presented is new, the product of analyses not previously published in any form.

The injury fact book

Since its development, the Strengths and Difficulties Questionnaire (SDQ) has been widely used in both research and practice. The SDQ screens for positive and negative psychological attributes. This review aims to provide an overview of the psychometric properties of the SDQ for 4- to 12-year-olds. Results from 48 studies (N = 131,223) on reliability and validity of the parent and teacher SDQ are summarized quantitatively and descriptively. Internal consistency, test-retest reliability, and inter-rater agreement are satisfactory for the parent and teacher versions. At subscale level, the reliability of the teacher version seemed stronger compared to that of the parent version. Concerning validity, 15 out of 18 studies confirmed the five-factor structure. Correlations with other measures of psychopathology as well as the screening ability of the SDQ are sufficient. This review shows that the psychometric properties of the SDQ are strong, particularly for the teacher version. For practice, this implies that the use of the SDQ as a screening instrument should be continued. Longitudinal research studies should investigate predictive validity. For both practice and research, we emphasize the use of a multi-informant approach.

Relationship Between Foot Length and Gestational Age in Pakistan

ABSTRACT The typically developing siblings of children with disabilities are vulnerable to behavioral problems as they grow up in an environment of considerable stress. Yet, the needs and behavior problems of these siblings are often neglected especially in Pakistan. In this cross-sectional study, we assessed the behavior problems among siblings of children with developmental disabilities. The strength and difficulties questionnaire (SDQ) was administered on 250 siblings (aged 6–17 years) of children with a developmental disability (Autism, Intellectual disability (ID), Down Syndrome (DS), and Attention Deficit Hyperactive Disorder (ADHD)) attending special education institutions in Karachi, Pakistan. Multiple linear regression was applied to assess the relationship between SDQ scores and other demographic, parental, and disability-related factors. Adjusted beta coefficients were reported along with a 95% confidence interval. The average SDQ score was found to be 14 ± 6 among the siblings of children with developmental disabilities. Multivariable analysis showed that the estimated mean SDQ score was almost twice among siblings of children with ADHD (95% CI: 0.73–3.48) and ID (95% CI: 0.64–3.16) than siblings of children with Down syndrome. Also, the mean SDQ score was 8 units higher among siblings of children with a severe developmental disability compared to mild disability (95% CI: 6.79–9.47). The findings of the current study emphasize the need for appropriate mental health services, using a family-focused approach from therapeutic and counseling platforms to the siblings, parents, and disabled brother/sister for early identification and management of behavior issues.

Behavioral problems and its associated factors among siblings of children with developmental disabilities: analytical cross-sectional study

The incidence of vaccine preventable disease in Pakistan remains high despite a long-standing Expanded Program on Immunization (EPI). We describe vaccine completeness, timeliness and determinants of coverage from a remote rural cohort (2012–2014). Vaccination histories were taken from EPI records. Vaccination was complete if all doses were received according to the EPI schedule and timely if doses were not ≥3 days early or ≥ 28 days late. Three models are presented: a multivariable logistic regression of household demographic and socioeconomic factors associated with complete vaccination, a multivariable mixed effects logistic regression assessing whether or not the vaccine was administered late (versus on-time), and a mixed effects multivariable Poisson regression model analysing the interval (in days) between vaccine doses. Of 959 enrolled children with full vaccination histories, 88.2 and 65.1% were fully vaccinated following either the pentavalent or DPT/HBV schedules if measles was excluded; coverage dropped to 50.0 and 27.1% when both doses of measles were included. Sixty-four (6.7%) were unvaccinated. Coverage and timeliness declined with subsequent doses. Migrating into the village after 1995 (95%CI 1.88 to 5.17) was associated with late vaccination. Being male, having an older father, and having parents with at least some formal education reduced the likelihood of a late dose. The interval between doses was consistent at 5 weeks (compared with the 4 weeks recommended by EPI). None of the socio-demographic variables were related to the likelihood of receiving full coverage. Vaccine coverage in Oshikhandass was higher than national averages. Measles vaccine coverage and timeliness were low; special consideration should be paid to this vaccine. The local vaccination schedule differed from the EPI, but the consistency suggests good local administration.
