Stress-coping strategies identified from school age children's perspective.

School age children, 8 to 12 years old (N = 103), reported on the strategies they use to help them deal with stressors. Individual questionnaires contained 518 coping strategies that were sorted into 13 categories inductively derived from the content of the behaviors. Girls named significantly more social support and emotional behaviors than boys, while boys named significantly more physical exercise activities than girls. Examination of the data by age revealed significant differences in the frequency with which all categories of strategies were used except for aggressive motor and spiritual activities. The data also revealed particular strategies that were used in different stages of the coping process, and strategies that the children perceived to be helpful versus not helpful to them.

The stress-coping process in school-age children: gaps in the knowledge needed for health promotion.

Most health promotion research on the stress-coping process among children has applied theory developed by adults for adults, with little examination of its applicability. Most instruments used with children have been developed from an adult perspective of what is stressful to children and how children should cope, with little validation of the accuracy of such instruments by the children themselves. Recommendations for further development of theory about and knowledge of the stress-coping process and relevant health promotion interventions from the children's perspective are offered.

The differential release of basal ATPase, Ca2+-dependent ATPase, 5'-nucleotidase and cholesterol during homogenization of skeletal muscle.

The influence of homogenization times on the presence of constituents in the microsomal fraction of skeletal muscle was investigated. Membranes having Ca2+-activated ATPase activity have a fragmentation pattern distinct from that of membranes displaying Ca2+-independent or basal ATPase activity. These latter membranes were found in highest specific concentration in the microsomal fraction prepared from homogenates subjected to short periods of homogenization. 5'-Nucleotidase (EC 3.1.3.5) activity paralleled that of basal ATPase on short periods of homogenization, as also did the specific concentration of cholesterol. Longer periods of homogenization led to a decrease in the specific activity of basal atpase, which reached its lowest value at 120s of homogenization, whereas the specific activity of 5'-nucleotidase and the specific concentration of cholesterol decreased initially in a similar manner to basal ATPase, but both increased substantially after the longest period of homogenization.
