The project appears to be positively affecting allied health students' perceptions and opinions of rural health practices and willingness to work in rural areas. Although long-term goals have yet to be accomplished, early indicators show benefits to the students and the community at-large, suggesting that the current program strategies are appropriate connectors between allied health students and rural communities.

Though the positive link between physical activity and maternal health is well documented, physical activity declines during pregnancy and, internationally, rural mothers are less likely than urban mothers to engage in physical activity. Some evidence suggests that self-efficacy is related to sustained engagement in physical activity. The purpose of this study was to examine self-efficacy, perceived benefits, and knowledge of safe exercise among 88 rural pregnant women in a southeastern region of the United States. Exercise self-efficacy was significantly related to maternal age and gestation. Women over age 26 years, and those in the second and third trimesters, scored significantly higher than younger women or those in the first trimester. Fifty-two percent (n = 46) of participants perceived that activity would decrease energy levels, 37.5% (n = 33) did not know that exercise can decrease the risk of gestational diabetes, and 47.6% (n = 41) were unaware that a mother who is overweight is more likely to have an overweight child. Results confirm a need for education to improve women's knowledge about health benefits and safety information related to physical activity during pregnancy.

This study examined the plasma glucose, free fatty acids (NEFA), lactate, triglyceride, cortisol, and insulin responses of pregnant women (22-28 wk) to a 40-min aerobic dance program and 40-min treadmill walking at similar heart rate intensities. The heart rates during exercise averaged 135 +/- 5 bt.min-1 for both trials. Immediate post-exercise plasma glucose levels were lower than resting levels for both exercise trials (P < 0.05), and remained below resting levels 20 min after exercise. Plasma triglycerides and NEFA were increased immediately post-exercise (P < 0.05), and returned toward rest 20 min after exercise. The NEFA responses at the end of the walking trials were significantly greater than at the end of the aerobic dance trials (P < 0.05). For both trials, immediate post-exercise plasma insulin levels were below resting levels (P < 0.05) and remained attenuated 20 min post-exercise. Plasma cortisol concentrations were unchanged throughout the aerobic dance trial. However, a mean increase of 105 nmol.l-1 immediately post-exercise was evident during the walking trials (P < 0.05). The results suggest that 40 min of walking or aerobic dance reduces blood glucose but does not cause hypoglycemia. Further, the results suggest that 40 min of walking or aerobic dance does not expose the mother to serious metabolic consequences that might adversely affect the fetus.

The health benefits of regular exercise are well documented, yet there has been limited success in the promotion of regular exercise in older African American women. Based on theoretical and evidence-based findings, the authors recommend a behavioral self-efficacy approach to guide exercise interventions in this high-risk population. Interventions should be developed that are age appropriate, group delivered in the community, focused on a single behavior, and only include general health education as a secondary purpose. Suggested cultural tailoring of exercise interventions includes addressing beliefs about exercise, focusing on the "possible self," promoting participants as "cultural consultants," and spiritual and religious strategies.
