Physical activity staging distribution: establishing a heuristic using multiple studies.

The purpose of this study was to identify the population prevalence across the stages of change (SoC) for regular physical activity and to establish the prevalence of people at risk. With support from the National Institutes of Health, the American Heart Association, and the Robert Wood Johnson Foundation, nine Behavior Change Consortium studies with a common physical activity SoC measure agreed to collaborate and share data. The distribution pattern identified in these predominantly reactively recruited studies was Precontemplation (PC) = 5% (+/- 10), Contemplation (C) = 10% (+/- 10), Preparation (P) = 40% (+/- 10), Action = 10% (+/- 10), and Maintenance = 35% (+/- 10). With reactively recruited studies, it can be anticipated that there will be a higher percentage of the sample that is ready to change and a greater percentage of currently active people compared to random representative samples. The at-risk stage distribution (i.e., those not at criteria or PC, C, and P) was approximately 10% PC, 20% C, and 70% P in specific samples and approximately 20% PC, 10% C, and 70% P in the clinical samples. Knowing SoC heuristics can inform public health practitioners and policymakers about the population's motivation for physical activity, help track changes over time, and assist in the allocation of resources.

High-level production of human parathyroid hormone (hPTH) by induced expression in Saccharomyces cerevisiae.

Saccharomyces cerevisiae was used as host for high-level production of intact human parathyroid hormone (hPTH). The yield increased about 30-fold by changing from the constitutive MFalpha promoter to the inducible CUP1 promoter in the expression cassettes, use of another host strain, and optimization of growth conditions where especially the pH value was crucial. The secreted products consisted mainly of intact hormone, hPTH(1-84). In addition, two C-terminally truncated forms that lacked the four or five last amino acid residues, hPTH(1-80) and hPTH(1-79), were identified. These hPTH forms migrated aberrantly by SDS-PAGE as 14-kDa proteins, while the real masses measured by mass spectrometry on HPLC-purified products were about 9 kDa. Availability of such easily purified truncated forms will be valuable for studies of how the C-terminal residues affect the structure and function of the hormone. Combination of mutations and disruptions of the host genes encoding proteinase A, B, carboxypeptidase Y, and Kex1p or Mkc7p did not influence the C-terminal deletions. The secretion of hPTH could be enhanced by overexpression of the yeast syntaxin gene SSO2, but the total level of the hormone was not improved due to impaired growth.

Effects of a multidimensional anabolic steroid prevention intervention. The Adolescents Training and Learning to Avoid Steroids (ATLAS) Program.

OBJECTIVE: To test a team-based, educational intervention designed to reduce adolescent athletes' intent to use anabolic androgenic steroids (AAS). DESIGN: Randomized prospective trial. SETTING: Thirty-one high school football teams in the Portland, Ore, area. PARTICIPANTS: Seven hundred two adolescent football players at experimental schools; 804 players at control schools. INTERVENTION: Seven weekly, 50-minute class sessions were delivered by coaches and student team leaders, addressing AAS effects, sports nutrition and strength-training alternatives to AAS use, drug refusal role play, and anti-AAS media messages. Seven weight-room sessions were taught by research staff. Parents received written information and were invited to a discussion session. MAIN OUTCOME MEASURES: Questionnaires before and after intervention and at 9- or 12-month follow-up, assessing AAS use risk factors, knowledge and attitudes concerning AAS, sports nutrition and exercise knowledge and behaviors, and intentions to use AAS. RESULTS: Compared with controls, experimental subjects at the long-term follow-up had increased understanding of AAS effects, greater belief in personal vulnerability to the adverse consequences of AAS, improved drug refusal skills, less belief in AAS-promoting media messages, increased belief in the team as an information source, improved perception of athletic abilities and strength-training self-efficacy, improved nutrition and exercise behaviors, and reduced intentions to use AAS. Many other beneficial program effects remained significant at the long-term follow-up. CONCLUSIONS: This AAS prevention program enhanced healthy behaviors, reduced factors that encourage AAS use, and lowered intent to use AAS. These changes were sustained over the period of 1 year. Team-based interventions appear to be an effective approach to improve adolescent behaviors and reduce drug use risk factors.

The Adolescents Training and Learning to Avoid Steroids (ATLAS) prevention program. Background and results of a model intervention.

OBJECTIVE: To develop and test a school-based intervention to prevent anabolic androgenic steroid use among high-risk adolescent athletes. DESIGN: Nonrandom controlled trial. SETTING: Two urban high schools. PARTICIPANTS: Fifty-six adolescent football players at the experimental school and 24 players at the control school. INTERVENTION: Eight weekly, 1-hour classroom sessions delivered by the coach and adolescent team leaders, and eight weight-room sessions delivered by research staff. The intervention addressed sports nutrition and strength training as alternatives to steroid use, drug refusal role play, and antisteroid media campaigns. OUTCOME MEASURES: A preintervention and postintervention questionnaire that assessed attitudes toward and intent to use steroids and other drugs; knowledge of drug effects; and diet, exercise, and related constructs. RESULTS: Compared with controls, experimental subjects were significantly less interested in trying steroids after the intervention, were less likely to want to use them even if their friends used them, were less likely to believe steroid use was a good idea, believed steroids were more dangerous, had better knowledge of alternatives to steroid use, had improved body image, increased their knowledge of diet supplements, and had less belief in these supplements as beneficial. CONCLUSIONS: Significant beneficial effects were found despite the sample size, suggesting that the effects of the intervention was large. This outcome trial demonstrates an effective anabolic androgenic steroid prevention program for adolescent athletes, and the potential of team-based interventions to enhance adolescents' health.

Long-term follow-up of a cohort of children with alpha-1-antitrypsin deficiency.

We assessed lung function, liver function, and smoking attitudes and behavior in 22 adolescents with homozygous alpha 1-antitrypsin deficiency whose condition had been detected through neonatal screening in the early 1970s. All subjects had normal lung volumes, expiratory flow rates, and diffusing capacity except for two siblings with mild asthma whose values reverted to the normal range after administration of an inhaled bronchodilator. Liver function was normal in all subjects with the exception of one boy who had an isolated elevation of alkaline phosphatase activity. Smoking attitudes, as determined by questionnaire, did not differ from those of 130 control subjects, but smoking initiation rates were significantly lower (p = 0.02). We believe that the issue of neonatal screening for alpha 1-antitrypsin deficiency should be reexamined because augmentation therapy for adults with emphysema is now available, and screening followed by family-based smoking intervention may lead to a nonsmoking life-style. The latter is especially important because the current weight of epidemiologic evidence strongly suggests that in nonsmokers with this condition, severe emphysema may never develop or, if it does, it will do so at a much later age than in smokers.
