Women, infants, and children cash value voucher (CVV) use in Arizona: a qualitative exploration of barriers and strategies related to fruit and vegetable purchases.

OBJECTIVE: Women, Infants, and Children (WIC) cash value vouchers (CVV) have been inconsistently redeemed in Arizona. The objective of this study was to explore perceived barriers to use of CVV as well as strategies participants use to overcome them. DESIGN: Eight focus groups were conducted to explore attitudes and behaviors related to CVV use. SETTING: Focus groups were conducted at 2 WIC clinics in metro-Phoenix, AZ. PARTICIPANTS: Participants in WIC who were at least 18 years of age and primarily responsible for buying and preparing food for their households. PHENOMENON OF INTEREST: Perceived barriers to CVV use and strategies used to maximize their purchasing value. ANALYSIS: Transcripts were analyzed using a general inductive approach to identify emergent themes. RESULTS: Among 41 participants, multiple perceived barriers emerged, such as negative interactions in stores or confusion over WIC rules. Among experienced shoppers, WIC strategies also emerged to deal with barriers and maximize CVV value, including strategic choice of times and locations at which to shop and use of price-matching, rewards points, and other ways to increase purchasing power. CONCLUSIONS AND IMPLICATIONS: Arizona WIC participants perceived barriers that limit easy redemption of CVV. Useful strategies were also identified that could be important to explore further to improve WIC CVV purchasing experiences.

Exploring the meaning of excess child weight and health: shared viewpoints of Mexican parents of preschool children.

In the United States, the prevalence of childhood overweight and obesity has reached epidemic levels, with U.S. Hispanic children, a sub-group mainly composed of children of Mexican decent, disproportionately affected. Prior research has suggested that Mexican parents may view overweight in early childhood as desirable; however, it is unclear if this is still the case. Therefore, this qualitative study explored the beliefs of 11 Mexican parents of preschoolers regarding weight and health. Following coding and clustering of themes from the transcribed audio-recorded meetings, six patterns were identified: (a) meanings and relationships about excess weight in childhood and child health, (b) causes of overweight and obesity, (c) uncertainty about knowing and not knowing, (d) from Mexico to America: enticements of a new land and time as a commodity, (e) the effects of society on personal and parental goals: the work of parenting in the United States, and (f) identified needs and action strategies. In summary, parents involved in this group discussion readily associated overweight/obesity with poor mental and physical health; however, they were uncertain how they would "know" if their children were overweight.

Weight loss practices and body weight perceptions among US college students.

OBJECTIVE: The authors assessed associations between body weight perception and weight loss strategies. PARTICIPANTS: They randomly selected male and female college students (N = 38,204). METHODS: The authors conducted a secondary data analysis of the rates of weight loss strategies and body weight perception among students who completed the National College Health Assessment survey. RESULTS: Half of respondents (50%) were trying to lose weight, although only 28% of students were overweight or obese. Also, 12% of respondents had inaccurate body weight perception. Women and men with inaccurate body weight perception were significantly more likely to engage in inappropriate weight loss strategies than were those with accurate body weight perception. Of all students attempting to lose weight, 38% used both diet and exercise. CONCLUSIONS: These data show that college students are interested in weight loss and that body weight perception plays an important role in the desire to lose weight.

Undergraduate dietetics programs do not support training students in smoking cessation.

Although tobacco use is the leading contributor to death and disability in the United States, allied health professionals often lack knowledge of smoking cessation techniques. The objective of this study was to identify the extent to which undergraduate dietetics programs (referred to as didactic programs in dietetics [DPD]) teach about tobacco and smoking cessation interventions and also DPD directors' opinions regarding tobacco and smoking cessation in dietetics education. All DPD directors in the United States (n=231) were sent a questionnaire to assess programs' and directors' demographics, courses that included tobacco and smoking cessation education, and directors' opinions pertaining to tobacco and smoking cessation education. The response rate was 49% (n=113). On average, DPD directors did not agree that tobacco and smoking cessation education should be a formal part of undergraduate dietetics programs and that it is not as important as other content areas required of dietetics students. Just 37% of directors believed that a dietitian's job responsibility included educating patients on smoking cessation. Only 7% of DPD directors had formal education on smoking cessation and tobacco use, but 53% had formal education on behavior modification. More than half of DPD programs (56%) did not offer any courses that provided tobacco and smoking cessation education. These results indicate that most undergraduate dietetics programs do not incorporate tobacco and smoking cessation education in their curricula. Dietetics and other allied health educators could consider including smoking cessation education in their curricula to ensure that future health professionals can contribute to Healthy People 2010 objectives related to smoking cessation.

Monounsaturated fatty acid intake by children and adults: temporal trends and demographic differences.

Epidemiologic evidence suggests that dietary monounsaturated fatty acids (MUFA) may have a beneficial health effect. Twenty-four-hour dietary intake data collected on 10-year-olds from 1978 to 1994 and on children and adults (ages 0-30 years) were examined for time, age, gender, ethnic, and geographic location differences in MUFA intake. Children's percent energy from MUFA decreased significantly from 1978 (14.1%) to 1994 (11.9%) with intake of oleic acid decreasing from 33.9 g/day (1973) to 25.7 g/day (1994). In 1994-96, percent energy from MUFA was 13% for children and adults aged 12 to 30 years, with 5% from palmitoleic acid and 93% from oleic acid. Males and blacks had significantly higher MUFA intake across all age groups than females and whites. Intakes of MUFA increased from 0 to 11 years of age to young adulthood (12-19 years), with no further increase at 20 to 30 years of age. Intakes of MUFA were lowest in the Northeast and highest in the Midwest. There were differences in food sources of MUFA by age group. For children 0 to 5 years of age, major sources were whole milk, peanut butter, 2% milk, and French fries; for children 6 to 11 years of age, major sources were whole milk, peanut butter, French fries, and 2% milk; for children 12 to 19 years of age, French fries, salt snacks, whole milk, and meat pizza were the major sources; for adults, French fries, whole milk, potato chips, and ground beef were the most common sources of MUFA. U.S. children and adults displayed temporal trends and demographic differences in intakes and food sources of MUFA. The implications of these changes and differences on biologic risk factors for specific chronic diseases warrant further investigation.

Beverage consumption and risk of obesity among Native Americans in Arizona.

Native Americans face some of the highest rates of obesity and diabetes in the world. Despite numerous education programs to reduce obesity among Native Americans, little attention has been paid to reducing fructose, particularly in the form of high-fructose corn syrup in beverages. Considerable data indicate that energy from beverages does not displace energy from other foods throughout the day, often leading to energy imbalance, and numerous studies have documented that beverages are a leading contributor to energy intakes among Native Americans. Prevention programs that target pregnant women and parents of infants and very young children are necessary to halt the epidemic of obesity among Native Americans; one approach may be by promoting sugar-free beverages.

Vitamin C deficiency and depletion in the United States: the Third National Health and Nutrition Examination Survey, 1988 to 1994.

OBJECTIVES: We sought to determine prevalence rates of vitamin C deficiency and depletion in the United States. METHODS: We used data from the Third National Health and Nutrition Examination Survey to assess intake of dietary, supplemental, and serum vitamin C. RESULTS: Mean intakes and serum levels of vitamin C were normal; however, vitamin C deficiency and depletion were common (occurring among 5%-17% and 13%-23% of respondents, respectively). Smokers, those who did not use supplements, and non-Hispanic Black males had elevated risks of vitamin C deficiency, while Mexican Americans had lower risks. CONCLUSIONS: Health professionals should recommend consumption of vegetables and fruits rich in vitamin C and should recommend supplementation for individuals at risk of vitamin C deficiency.

Race-, gender- and age-specific differences in dietary micronutrient intakes of US children.

Race-, gender- and age-specific differences in dietary micronutrient intakes of 1- to 10-year-old US children were evaluated. Three-day, dietary intakes from the US Department of Agriculture's Continuing Survey of Food Intakes by Individuals were evaluated. Data from 1895 children (967 males, 928 females; 1,540 Whites, 355 Blacks) who resided in the 48 conterminous states were analyzed. Micronutrient intakes, intakes as percent of the Recommended Dietary Allowance (RDA) and percent of children who consumed < or =67% of the RDA were computed. Black males compared with White males, Black females compared with White females and White females compared with White males had significantly lower dietary intakes for several micronutrients. More Black males than White males had intakes < or =67% of the RDA for vitamin E, calcium and zinc. Blacks and female children were at a greater risk for vitamin A, vitamin E, calcium, iron and zinc deficiency.

Position of the American Dietetic Association: the role of dietetics professionals in health promotion and disease prevention.

In the United States, the leading determinants of morbidity and mortality are rooted in behavioral choices related to eating habits, exercise, tobacco, alcohol consumption, and stress reduction. Scientific data consistently provide evidence that diet plays an important role in health promotion and disease prevention. Healthy eating habits--coupled with other healthful lifestyle behaviors--have the potential to reduce the risk of chronic disease. Health care typically assumes a curative or treatment role in the United States. However, dietetics professionals are shaping an alternate view of health, which includes developing healthy public policies, creating safe and supportive environments, building communities and coalitions, and reorienting health services to include health promotion as a primary approach to delivering health care. Individual-level approaches, such as counseling and group education, have been employed most often in modifying health behaviors. However, population-level approaches that affect availability of or access to healthy foods, opportunities for physical activity, and other healthy lifestyle determinants also are important. Dietetics professionals have pivotal roles in both individual- and population-level approaches.

Creatine supplementation influences substrate utilization at rest.

The influence of creatine supplementation on substrate utilization during rest was investigated using a double-blind crossover design. Ten active men participated in 12 wk of weight training and were given creatine and placebo (20 g/day for 4 days, then 2 g/day for 17 days) in two trials separated by a 4-wk washout. Body composition, substrate utilization, and strength were assessed after weeks 2, 5, 9, and 12. Maximal isometric contraction [1 repetition maximum (RM)] leg press increased significantly (P < 0.05) after both treatments, but 1-RM bench press was increased (33 +/- 8 kg, P < 0.05) only after creatine. Total body mass increased (1.6 +/- 0.5 kg, P < 0.05) after creatine but not after placebo. Significant (P < 0.05) increases in fat-free mass were found after creatine and placebo supplementation (1.9 +/- 0.8 and 2.2 +/- 0.7 kg, respectively). Fat mass did not change significantly with creatine but decreased after the placebo trial (-2.4 +/- 0.8 kg, P < 0.05). Carbohydrate oxidation was increased by creatine (8.9 +/- 4.0%, P < 0.05), whereas there was a trend for increased respiratory exchange ratio after creatine supplementation (0.03 +/- 0.01, P = 0.07). Changes in substrate oxidation may influence the inhibition of fat mass loss associated with creatine after weight training.
