What can you do to improve the environment?

Medicine has a dual obligation concerning the environment: (1) to supply laboratory and clinical research to document harmful effects on the environment, and (2) to encourage changes in the environment to reduce or eliminate adverse health effects. This article presents individual and group actions for the improvement of the environment. The American Academy of Otolaryngology-Head and Neck Surgery has developed a medical office pledge, "The Greening of Our Office for Improvement of Our Environment." Physicians are encouraged to agree to certain principles for environmental improvement.

Circuit weight training in early cardiac rehabilitation.

A prospective, randomized study evaluated the feasibility, safety, and efficacy of upper body circuit weight training (CWT) in 25 stable male cardiac patients entering the initial out-of-hospital phase of cardiac rehabilitation. Both groups performed 30 minutes of aerobic exercise only for 6 weeks. The aerobic exercise group (N = 13) continued this regimen for 6 more weeks, during which time the CWT group (N = 12) performed 15 minutes of aerobic exercise followed by CWT (two loops, eight upper body exercises). The only adverse response was in one CWT patient in whom restenosis developed. Peak heart rate during aerobic exercise and CWT was similar, but peak systolic blood pressure during aerobic exercise was significantly greater than during CWT. Peak rate pressure product during aerobic exercise and CWT was similar. Treadmill time increased significantly in both groups. Upper body strength (cumulative pounds lifted) increased significantly only in the CWT group. A coordinated program of CWT and aerobic exercise can be performed safely in stable cardiac patients during phase 2 cardiac rehabilitation, resulting in improved upper body strength and aerobic capacity.

Exercise and prevention of coronary heart disease.

Exercise programs can be used to improve functional capacity, lower the myocardial energy cost of performing work, and favorably alter one's cardiovascular risk profile. In addition, a large body of data support the role of exercise in the primary prevention of coronary heart disease. Standardized exercise programs are safe and effective for a large majority of patients.

Maternal sociomedical characteristics and birth weights of firstborns.

Pregnancy outcome and sociomedical characteristics were examined in a sample of 1844 black and white primiparous females who received prenatal care. White females were more frequently married and more likely to live with their husbands than with their parents. Black females were better educated and more interested in obtaining further education. White women smoked significantly more cigarettes. There were no differences in contraceptive use in black and white females. Number of prenatal visits was least frequent among adolescent black females. With the exception of a higher incidence of vaginal infection among black females, there were no significant differences in general health status. There were no differences in birth weights between the firstborns of black and white adolescents, but adult white females had significantly heavier firstborns than blacks. Nonetheless, no differences were found in prevalence of low birth weight-for-gestational neonates between black and white females. Infrequent prenatal visits, maternal diabetes and smoking were the only significant multivariate factors associated with the occurrence of a low birth weight-for-gestational age neonate among the total sample.
