Walking campaign: a model for developing participation in physical activity? Experiences from three campaign periods of the Stockholm Diabetes Prevention Program (SDPP).

The Stockholm Diabetes Prevention Program (SDPP) is implementing a model for community-based intervention of type 2 diabetes in three municipalities, of which one has focused on increasing physical activity among the inhabitants. The purpose was to emphasize the integration of walking into daily routines. The campaign was promoted throughout residential areas, organizations and local media. Leaders for organized walking were recruited as volunteers by advertising in local media. After a short education in leadership, practice, and first aid, the 27 volunteers ran organized walking groups in several residential areas. During three of seven walking campaigns the participants were followed and evaluated. The study showed that those individuals who participated one to three times a week were predominantly married women with a good health and regular physical activity. Nevertheless, more important was that one third of the participants had never been exercising regularly before. Most remarkable was to find the voluntary leaders so easily recruited and their great interest to remain as leaders for walking tours.

Sexual functions of mice neonatally exposed to DDT or pcb.

Since DDT and PCB occur in milk, young animals may ingest these substances during the critical period of neonatal life; For this reason lactating mice were given injections of DDT or PCB, 50 mg/kg body weight, once a week for four weeks, the first injection being administered on the day of delivery. The reproductive capacity of their young was studied by measuring the frequency of implanted ova. When both the male and the female of a mating pair had been nursed by DDT- or PCB-treated mothers this frequency decreased from 94% in the controls to 79 and 75% respectively. No significant decrease were found when only one of the mated animals in the pair had been nursed by a treated mother.
