Nutrition knowledge and attitudes of physician assistants in Texas

Physician Assistants (PAs) are increasingly assuming more responsibilities as "front-line" health providers due to emphasis on primary care and cost-containment in the rapidly changing health care environment. Nutrition plays an important role in health promotion and disease prevention. Primary care providers, including PAs, have enormous potential as nutrition counselors and advocates. There have been no studies to date that address the PAs' adequacy of nutrition education or their attitudes toward the value of nutrition. Therefore, it was the purpose of the study to determine the nutrition knowledge and attitudes of PAs in Texas.^ All certified physician assistants in Texas were eligible for the study. A mailed survey was sent to 1,482 PAs in Texas with a response rate of 54.2%. The sample utilized for data analysis was 764 PAs.^ The study compared the nutrition knowledge mean scores for PAs who graduated from a PA program greater than 11 years ago with those who graduated less than 11 years ago. The study also examined Texas PAs' attitudes about their nutrition education training, the value of nutrition counseling, and their perceived ability to provide such nutrition counseling. Demographic and practice information was collected from the PAs. Demographically, PAs in Texas were found to be comparable to the national population of PAs surveyed in 1996.^ The overall mean level of nutrition knowledge was 70% correct. The mean level of nutrition knowledge was significantly related to the type of PA program that the PA graduated from (i.e., Certificate only or Master's degree level). No significant relationships were found between the mean nutrition knowledge score and age, year of graduation, length of practice, or the type of nutrition education provided in PA program.^ The majority of the PAs surveyed felt that diet and nutrition has an important role in disease prevention and felt that PA programs should place a greater emphasis on nutrition education. Many PAs surveyed were not satisfied with the amount of nutrition education they had received in their PA education programs and were not confident in their ability to provide nutrition counseling to patients.^ Suggestions are offered for improvement in PA nutrition education in the areas of both nutrition knowledge and patient counseling skills. In addition, this study recommends developing and strengthening partnerships between PAs and nutrition organizations. ^

Effects of a health advocacy program to promote physical activity and nutrition behaviors among adolescents: An evaluation of the Young Leaders for Healthy Change program

Background. This study was designed to evaluate the effects of the Young Leaders for Healthy Change program, an internet-delivered program in the school setting that emphasized health advocacy skills-development, on nutrition and physical activity behaviors among older adolescents (13–18 years). The program consisted of online curricular modules, training modules, social media, peer and parental support, and a community service project. Module content was developed based on Social Cognitive Theory and known determinants of behavior for older adolescents. ^ Methods. Of the 283 students who participated in the fall 2011 YL program, 38 students participated in at least ten of the 12 weeks and were eligible for this study. This study used a single group-only pretest/posttest evaluation design. Participants were 68% female, 58% white/Caucasian, 74% 10th or 11th graders, and 89% mostly A and/or B students. The primary behavioral outcomes for this analysis were participation in 60-minutes of physical activity per day, 20-minutes of vigorous- or moderate- intensity physical activity (MVPA) participation per day, television and computer time, fruit and vegetable (FV) intake, sugar-sweetened beverage intake, and consumption of breakfast, home-cooked meals, and fast food. Other outcomes included knowledge, beliefs, and attitudes related to healthy eating, physical activity, and advocacy skills. ^ Findings. Among the 38 participants, no significant changes in any variables were observed. However, among those who did not previously meet behavioral goals there was an 89% increase in students who participated in more than 20 minutes of MVPA per day and a 58% increase in students who ate home-cooked meals 5–7 days per week. The majority of participants met program goals related to knowledge, beliefs, and attitudes prior to the start of the program. Participants reported either maintaining or improving to the goal at posttest for all items except FV intake knowledge, taste and affordability of healthy foods, interest in teaching others about being healthy, and ease of finding ways to advocate in the community. ^ Conclusions. The results of this evaluation indicated that promoting healthy behaviors requires different strategies than maintaining healthy behaviors among high school students. In the school setting, programs need to target the promotion and maintenance of health behaviors to engage all students who participate in the program as part of a class or club activity. Tailoring the program using screening and modifying strategies to meet the needs of all students may increase the potential reach of the program. The Transtheoretical Model may provide information on how to develop a tailored program. Additional research on how to utilize the constructs of TTM effectively among high school students needs to be conducted. Further evaluation studies should employ a more expansive evaluation to assess the long-term effectiveness of health advocacy programming.^

Supplemental Nutrition Assistance Program: A policy analysis of restricting foods with minimal nutritional value

In 2011, expenditures for the Supplemental Nutrition Assistance Program (SNAP) reached an all-time high of $72 billion. The goal of SNAP is " to alleviate hunger and malnutrition…by increasing food purchasing power for all eligible households who apply for participation." It has been well established that proper nutrition is essential to good health, making SNAP an important program to public health consumers. Thus, this analysis examined whether SNAP is meeting its stated goal and whether the goal would be reduced if the purchase of foods of minimal nutritional value (FMNV) were restricted. ^ A review of existing literature found that SNAP has been shown to alleviate hunger, but the studies on the nutritional impact of the program were not sufficient to assert whether change is needed. When considering whether limiting FMNV would reduce or improve the effectiveness of SNAP at alleviating hunger and malnutrition, there is very little information on which to base a policy change, particular one that singles out a low income group to restrict purchases. ^ Several states have attempted to restrict the purchase of FMNV but, to date, no such change has been implemented or tested. Conducting pilot studies on the restriction of FMNV, along with better data collection on SNAP purchases, would guide policy changes to the program. Although there are many potential public health benefits to restricting FMNV purchase using SNAP dollars, research is needed to quantify the cost impact of these benefits.^
