Frequency of exercise and dropouts in a work-site program. Correlates of 6-month activity patterns.

Exercise professionals have little information concerning expected levels of exercise for new participants. This study examined the frequency of exercise of 949 employees during their first 6 months of membership in a work-site health promotion facility, using automated check-in data. Overall, the frequency of exercise declined, the proportion of frequent exercisers declined, and the proportion of employees who dropped out increased. Men exercised more frequently and were less likely to drop out than were women (P < .01). Younger employees exercised more frequently than did older employees. Employees in the middle salary level exercised more frequently than did employees in the lower or upper levels (P < .01). The employee groups that started out with a lower frequency of exercise remained at a lower frequency throughout the 6 months. By their 6th month, women were 50% more likely to drop out and 50% less likely to exercise regularly than were men. These figures provide a basis for comparison with other programs to document expected exercise behavior.

Dropouts in a long-term follow-up study involving voluntary counseling and HIV testing: experience from a cohort of police officers in Dar Es Salaam, Tanzania.

BACKGROUND: Results of most population-based studies primarily are derived from people who responded positively and thereby continued to participate in such studies. It is, however, equally important to know the characteristics of study subjects who drop out to learn the reasons that kept them from continuing to participate in the study, especially because they had initially agreed to participate in such a study. In studies with long-term follow-up, reasons for nonresponse may provide invaluable information that may be gathered through continued contact with study subjects who have withdrawn from the study. OBJECTIVES: To determine characteristics of study participants who withdrew from an ongoing study of police officers, which involved counseling and HIV testing, and to determine reasons for their discontinued participation. METHODS: Demographic characteristics of a cohort of police officers who had been participating in a study to determine their suitability for HIV vaccine trials were analyzed. Characteristics of those who did not return for the second survey of appointments for HIV testing were compared with those who continued their participation. A randomly selected sample of 132 police officers who did not participate in the second survey of HIV testing were asked why they did not return. Answers were obtained from 84 people who had discontinued their participation. RESULTS: Of eligible police officers, 2087 (72.1%) responded to the call for follow-up appointments, whereas 807 (27.9%) did not return. Those who did not return to participate in the second survey had significantly higher rates of HIV seropositivity (17.2%) than those who did return (13.5%) (p <.05). The rate of return in unmarried participants was worse (p <.05) than the rate among married participants. Rates of sexual contacts with partners other than their spouses and levels of alcohol consumption did not differ between the two groups. Reasons for dropping out of the study included fear of knowing results of HIV testing in 54.6%, lack of time to continue in 34.5%, and fears about job security in 3.6%. CONCLUSION: Fears of finding out that one might be seropositive need to be answered at recruitment, and practical arrangements must be made to facilitate further follow-up. A bias for lower incidence might be introduced in vaccine trials if participants thought to be at highest risk for HIV infection discontinue participation.

[3 osteosarcoma therapy dropouts. Clinical cases].

We report on 3 cases of male late-adolescent/young-adult osteogenic sarcoma patients who refused complete chemical therapy according to the treatment plan "COSS 80". They all originated from disturbed family situations. Characteristic was their early independence and autonomy, dominance tendency, low level of self control, and high level of sociability. Primary motivation for refusal was the experienced intolerability of the chemotherapeutical side-effects and extreme fear of medical procedures (e.g. injections).

Late dropouts from group psychotherapy.

In five outpatient groups totalling 42 patients, over one-third of the patients quit group treatment between six and twelve months. Interviews suggest that efforts at development of greater intimacy precipitated leaving. In two groups this created a wave effect, with further quitting of two or three additional patients. Therapists' lack of awareness of potential for late dropping out may have contributed to this.
