Children at-risk: child abuse in Denmark.

In Denmark there have been few case reports on child abuse, but only one epidemiological study conducted in 1969. We have therefore initiated a number of countrywide studies by contacting all pediatric departments, Institutes of Forensic Medicine and the public health officers in Denmark. The present study describes the findings from the city of Copenhagen during 1970-79. Only 27 children, mostly under seven years of age, were registered. Information on pregnancy, delivery, neonatal period and the children's former development provided significant findings. All the registered families belonged to the lowest social class, half of the children had a history of previous abuse, one third of siblings had also previously been abused and one third of the wives were "battered wives". In 2/3 of the cases the father-figure was the perpetrator. The study showed an urgent need for a more coherent policy on child abuse and child welfare, general guidelines on interdisciplinary work, communication, prevention, community work and follow-up. Practical guidelines for involvement with child abuse are proposed and it is recommended to establish child abuse teams in Denmark, also in order to deal with prevention at the pre- and postnatal level. The pediatric departments should get more involved with community and social work in order to deal with child abuse and neglect at an early stage, where the abuse can be prevented.

School health screening of a birth cohort: a prospective longitudinal study.

School age illnesses, coded according to the International Classification of Diseases (ICD) from information in 4 327 school health records, are reported for a perinatal cohort (The Copenhagen Perinatal Cohort 1959-61) comprising 9 125 successive live births. Although characteristic somatic disorders continue to arise, the medical picture is dominated by problems of a psycho-social nature. This finding suggests that the school health service should be adapted towards this changing pattern of child health.

Inspiratory muscle function following abdominal weight exercises in healthy subjects.

Three indexes of inspiratory muscle function were evaluated in 20 healthy young adults before and after a six-week program of diaphragmatic breathing exercises. Thrice weekly, each subject performed 30 maximal voluntary diaphragmatic contractions in the supine position with a moderately heavy weight (range: 7-23 kg, or 15.4-50.7 lb) placed on the anterior abdominal wall to resist diaphragmatic descent. This protocol failed to improve 1) inspiratory capacity, 2) peak inspiratory flow rate, and 3) maximal pressures generated by the inspiratory muscles under static conditions. These finding indicated that this commonly used isotonic exercise regimen does not increase the maximal shortening, velocity of shortening, or strength of the diaphragm in healthy subjects. On the other hand, most subjects increased the maximal weight they found tolerable, performed the exercise more rapidly, and reported that their initial discomfort either waned or disappeared by the end of the program. These latter observations suggest that the exercise program might have improved inspiratory muscle endurance.
