Determining the accuracy and relevance of mortality rates for extremely low birthweight infants

Family process and peer influences on substance use by adolescents

This study explores the association of family process and peer influences with risk behaviors of adolescents. A total of 805 students were recruited from secondary schools. The results showed that adolescents who have parents who are “authoritarian” (OR = 1.856) were more likely to smoke. Adolescents who have conflicts with their parents (OR = 1.423) were more likely to drink. Those who have parents who are “permissive” were less likely to drink (OR = 0.885). Having friends who smoked (OR = 5.446) or drank (OR = 1.894), and friends’ invitation to smoke (OR = 10.455) or drink (OR = 11.825) were the dominant contributors to adolescent smoking and drinking. Interventions are needed that recognize the strength of the parent-child relationship, as well as strengthen family functioning through improved interpersonal, parenting, and monitoring skills.

Don't ask, they won't tell: the quality of adolescent health screening in five practice settings

OBJECTIVES

This study examined the extent to which comprehensive, age-appropriate adolescent health screening is undertaken in the clinical setting and whether the extent of such screening varies by setting.

METHODS

Charts of adolescents 13 to 17 years old (n = 788) were randomly selected from five practice settings in Minneapolis, Minn. Each was assessed for the number of biomedical and sociobehavioral health risks screened.

RESULTS

In no practice setting was there screening to the level recommended. The two teen clinics screened more extensively for behavioral, psychosocial, substance use and sexual behavior risks than the community family practice setting, which, in turn, screened more extensively than either the private family practice or private pediatric practice settings, which did not differ from each other. Age differences and gender accounted for only small amounts of variance in total number of health risks screened, whereas differences among practice settings accounted for a larger amount.

CONCLUSIONS

Results suggest substantive deficiencies in private practice settings' implementation of preventive care screening protocols for adolescents.

Survival of low birthweight infants in central Queensland

The survival of low birthweight infants < or = 2000 g born in the central Queensland area during the years 1979 to 1991 was examined. Five hundred and sixty such infants were either delivered at one of the two Rockhampton obstetric units (Rockhampton Base Hospital and the Mater Misericordiae Hospital) or retrieved from outlying central Queensland areas. Both hospitals had intensive care nurseries capable of ventilation and infants were transferred to tertiary centres only for cardiac or surgical treatment. The study involved all liveborn infants, including those with lethal malformations and all deaths up to the time of discharge. Survival rates were as follows: < or = 500 g 0%, 501 < or = 750 g 30%, 751 < or = 1000 g 51%, 1001 < or = 1500 g 79%, 1501 < or = 2000 g 93%. The survival of Aboriginal infants and outborn infants were found to be essentially the same as the overall group.

Long-term outcome of infants born preterm

This chapter outlines some of the many long-term health problems to be expected in surviving preterm children. They have higher rates of sensorineural impairments (such as cerebral palsy, and visual, auditory and intellectual impairments) and sensorineural disabilities from these impairments, than children born at term. In addition, they grow poorly and have higher rates of other health problems, including poorer respiratory health in early childhood. There is little doubt that preterm children contribute disproportionately to the prevalence of health problems in childhood. However, there are still many gaps in our knowledge of the outcome for preterm survivors, particularly regarding outcome in adulthood. Obstetricians and neonatologists working in intensive care, as well as parents, want to know the long-term outcome for preterm children born today, not that of children born a generation ago when fewer preterm children (particularly those of extremely low birthweight) survived. Despite the many problems, the conclusion is that most preterm children are as healthy as term children, suffering only usual childhood illnesses; we feel confident that the majority make, and will continue to make, useful contributions to their families and the societies in which they live.
