Adherence to exercise interventions in the treatment of hypercholesterolemia.

The goals of this study were to determine the rate of adherence to exercise treatment of hypercholesterolemia and to identify personality and demographic factors associated with adherence. Of the 31 subjects entering the 26-week program, 12 attended 80% or more of the scheduled sessions. Adherence was positively associated with the perceived seriousness of hypercholesterolemia, the expectation of benefit from treatment, and depressed feelings of helplessness and hopelessness. Negative associations were identified between adherence and the perception of health status being under the control of chance or of powerful others. Older subjects were more likely to be adherers at 8 and 16 weeks but not at 26 weeks.

White phosphorus poisoning of waterfowl in an Alaskan salt marsh.

The cause of the yearly death of an estimated 1,000 to 2,000 migrating dabbling ducks (Anas spp.) and 10 to 50 swans (Cygnus buccinator and C. columbianus) has remained a mystery for the last ten years in Eagle River Flats (ERF), a 1,000 ha estuarine salt marsh near Anchorage, Alaska, used for artillery training by the U.S. Army. We have gathered evidence that the cause of this mortality is the highly toxic, incendiary munition white phosphorus (P4). The symptoms of poisoning we observed in wild ducks included lethargy, repeated drinking, and head shaking and rolling. Death was preceded by convulsions. Farm-reared mallards dosed with white phosphorus showed nearly identical behavioral symptoms to those of wild ducks that became sick in ERF. White phosphorus does not occur in nature but was found in both the sediments where dabbling ducks and swans feed and in the gizzards of all carcasses collected in ERF. We hypothesize that feeding waterfowl are ingesting small particles of the highly toxic, incendiary munition P4 stored in the bottom anoxic sediments of shallow salt marsh ponds.

Children's conceptions of AIDS: a developmental analysis.

Examined causal reasoning about AIDS in children representing three major phases of cognitive development: prelogical, concrete logical, and formal logical thinking. 60 Ss (age groups: 5-7 years, 8-10 years, and 11-13 years) were administered the Concepts of AIDS Protocol. Responses were scored using the developmentally ordered Concepts of Illness Category System. The data confirm that, as a group, children's causal thinking about AIDS parallels the ways in which children think about illness in general. More specifically, the data could be organized in terms of 6 major categories or ways in which children conceptualize AIDS and its causes. The findings provide an initial empirical foundation for AIDS education curricula.
