Construct validity of a dietary protein assessment questionnaire to explore college students' knowledge and attitudes towards dietary protein.

Introduction: Misconceptions about dietary protein may exist due to unscientific information from commonly used sources such as social media. Understanding knowledge and attitudes towards protein is important for developing effective interventions to improve the dietary behaviors of U.S. college students. The objective of this study was to develop a questionnaire to evaluate college students' knowledge and attitudes towards dietary protein. Methods: The questionnaire had 64 questions, including 8 demographic, 24 knowledge, 14 attitude, and 18 behavior questions. Construct validity of the knowledge questions was assessed by performing known-group comparisons using an independent t-test. Exploratory factor analysis (EFA) with principal axis factoring and a promax rotation was used to evaluate the factor structure of the attitude questions. Results: Four hundred seventy participants (87.3% female) provided responses for the attitude questions. Fifty-five nutrition and Fifty-one non-nutrition students provided responses for the knowledge questions. Three factors were retained: animal protein sources' relationship with human and environmental health (Factor 1); organic protein sources (Factor 2); and adequacy of the protein recommended dietary allowance (RDA) for weight loss and vegetarian diets (Factor 3). Mean knowledge responses were 66.4 ± 11.5% and 47.6 ± 16.4% for nutrition and non-nutrition students, respectively (t-test p-value for difference <0.001). Conclusion: Protein attitudes appear multidimensional and correlated. Further testing is needed to confirm the three-factor model and to assess temporal reliability.

The Baby Bites Text Messaging Project with randomized controlled trial: texting to improve infant feeding practices.

Background: Rapid weight gain and overweight in infancy are associated with childhood obesity. Thus, effective, accessible interventions to promote healthy infant feeding practices to prevent early obesity are essential. Methods: This mixed-methods study involved diverse parents of infants in an urban, low-income pediatric clinic. Qualitative interviews explored parental attitudes towards feeding, early obesity, and communication with the pediatrician. A pilot, randomized controlled trial (RCT) informed by feedback provided by clinic parents compared text messages delivered for 12 months promoting healthy feeding practices to usual care to prevent early pediatric obesity. A computer-generated randomization schedule with balanced distribution for sex was used to place infants into groups. Weight-for-length percentiles and z-scores and feeding practices were measured at 0-2 weeks (baseline), 2-4 months, 6-9 months, and 12 months. Interviews were recorded, transcribed, and coded using thematic analysis. Weight for length percentile, Weight for length z scores, and feeding practices were compared between groups using repeated measures mixed analysis of variance (ANOVA). Results: Participants in the interviews were 15 parents of infants less than 1 month old. RCT participants were 38 parents of newborns (17 control; 21 intervention). Most parents in the qualitative evaluation viewed breastfeeding positively but also discussed barriers. Most also wanted practical information regarding infant feeding. There were no differences in weight-for-length percentile (F=0.52; P=0.60) or z-scores (F=0.7922; P=0.79), breastfeeding persistence χ2[1] =1.45, P=0.23, or age of introduction of solids in the intervention (statistical analysis not possible due to low counts) compared to the control group; however, low response to surveys limited the study's power. Conclusions: Text messaging has potential to extend the healthcare provider's communication beyond clinic. However, texting interventions should be flexible to mitigate barriers such as loss of phone service and challenges customizing messages to parent needs.

College Campus Food Pantry Program Evaluation: What Barriers Do Students Face to Access On-Campus Food Pantries?

The purpose of this study was to explore barriers Texas Woman's University (TWU) students face in accessing on-campus food pantries. This cross-sectional, survey-based study was conducted in Fall 2021. Students' use of the food pantries and barriers to utilization, including qualitative questions, were evaluated using descriptive statistics and thematic analyses. Students (n = 529) completed the survey. Despite a high prevalence of food insecurity (49.2%), most students reported never using the pantries (89.8%). Almost half of the students were unaware that these pantries existed on campus (47.8%). More than one in four students believed there were barriers to accessing the pantries, with time tissues, lack of transportation, limited food pantry hours of operation, and social stigma most commonly cited as major barriers to access. Food insecurity remains an urgent problem at TWU since the prevalence has remained high since 2019 despite the institutions' efforts to reduce it. One of those resources has not been utilized as expected, which might impede improvements in food security among students. TWU on-campus food pantries can use these findings to address major barriers by offering after-hours access through the libraries or campus police, partnering with public transportation, and normalizing accessing food assistance.

Health and Type 2 Diabetes Perspectives of At-Risk, Mexican-Origin Males (HD-MxOM): a Qualitative Study.

OBJECTIVE: To investigate perspectives of diabetes, nutrition, and health among underrepresented Mexican-origin males and elucidate on contributing factors of type 2 diabetes disparities. RESEARCH DESIGN: Audio-recorded, semi-structured interviews were conducted with 15 native Spanish-speaking, Mexican-origin males. Men were between the ages of 40 and 64 and at risk for type 2 diabetes-defined as > 40 years of age, BMI > 25, and sedentary over the last 3 months. Data collected included clinical measures (height, weight, waist circumference, blood pressure) and demographic characteristics (years living in the U.S., marital status, employment, occupational physical activity, income, educational attainment, and average physical activity levels). The audio recordings, each lasting approximately 60 min, were transcribed verbatim and underwent three-cycle coding with analysis for codebook formation, categorization, and thematic extraction. RESULTS: Barriers to engaging in health behaviors among Mexican-origin males include poor understanding of diabetes and nutrition, unreliable sources of health information, and socioeconomic status. Enablers of health neglect include intense perceptions of diabetes severity and a reactive health culture rooted in medical machismo and valemadrismo. Perspectives of personal responsibility and the desire to learn through culturally specific recommendations detail potential facilitators of health behaviors. CONCLUSION: The data convey a network of sociocultural factors that inhibit health prioritization and promote disease misconceptions among Mexican-origin males. Pragmatic, culturally tailored education represents serviceable strategies for health promotion and diabetes prevention. These findings explicate cultural considerations for educators and clinicians seeking optimization of programs and clinical interactions with Mexican-origin men.

Parent preferences for text messages containing infant feeding advice.

BACKGROUND: Text-messaging is beneficial in health promotion. Research on impact of message framing (gain- versus loss-framed) has had variable results, depending on type of behavior targeted. There is no research on framing of text-messaging to promote healthful infant feeding practices. METHODS: The purpose of this cross-sectional survey was to examine whether parents of infants aged three months or younger viewed gain- or loss-framed text messages as more helpful and which style was viewed as more likely to affect feeding practices. A secondary purpose was to determine what time of day and frequency of messaging was preferred. Parents were recruited from an urban pediatric medical clinic. PsychData was used to administer the survey. Parents rated message pairs targeting constructs of the Health Belief Model using a five-point Likert scale. Paired t- tests compared overall ratings for helpfulness and likelihood of messages affecting feeding practices between gain- and loss-framed messages. Descriptive and frequency analyses were applied to demographics and questions regarding preferred timing for receiving messages. RESULTS: A total of 34 parents (3 fathers and 31 mothers, mean age 26±5.5 years) completed the survey, with 41% enrolled in WIC and 29% in SNAP. There was no overall difference in helpfulness or likelihood of messages affecting feeding practices between gain- and loss-framed messages. Message style did not affect likelihood of adopting a feeding practice. However, gain framed messages relating to benefits and self-efficacy for breastfeeding were viewed more positively (mean =2.32; P=0.034; mean =1.79; P=0.041, respectively). The greatest proportion of parents (38%) preferred receiving messages once per week, and 50% preferred morning messages. CONCLUSIONS: Framing of text messages appeared to have little effect on parents' acceptance of messages related to infant feeding practices. Parents were receptive to receiving messages from their infant's healthcare provider once per week, in the morning.

Quercetin may suppress rat aberrant crypt foci formation by suppressing inflammatory mediators that influence proliferation and apoptosis.

The flavonoid quercetin suppresses cell proliferation and enhances apoptosis in vitro. In this study, we determined whether quercetin protects against colon cancer by regulating the protein level of phosphatidylinositol 3-kinase (PI 3-kinase) and Akt or by suppressing the expression of proinflammatory mediators [cyclooxygenase (COX)-1, COX-2, inducible nitric oxide synthase (iNOS)] during the aberrant crypt (AC) stage. Forty male rats were randomly assigned to receive diets containing quercetin (0 or 4.5 g/kg) and injected subcutaneously with saline or azoxymethane (AOM; 2 times during wk 3 and 4). The colon was resected 4 wk after the last AOM injection and samples were used to determine high multiplicity AC foci (HMACF; foci with >4 AC) number, colonocyte proliferation and apoptosis by immunohistochemistry, expression of PI 3-kinase (p85 and p85alpha subunits) and Akt by immunoblotting, and COX-1, COX-2, and iNOS expression by real time RT-PCR. Quercetin-fed rats had fewer (P = 0.033) HMACF. Relative to the control diet, quercetin lowered the proliferative index (P = 0.035) regardless of treatment and diminished the AOM-induced elevation in crypt column cell number (P = 0.044) and expansion of the proliferative zone (P = 0.021). The proportion of apoptotic colonocytes in AOM-injected rats increased with quercetin treatment (P = 0.014). Levels of p85 and p85alpha subunits of PI 3-kinase and total Akt were unaffected by dietary quercetin. However, quercetin tended to suppress (P < 0.06) the expression of COX-1 and COX-2. Expression of iNOS was elevated by AOM injection (P = 0.0001). In conclusion, quercetin suppresses the formation of early preneoplastic lesions in colon carcinogenesis, which occurred in concert with reductions in proliferation and increases in apoptosis. It is possible the effects on proliferation and apoptosis resulted from the tendency for quercetin to suppress the expression of proinflammatory mediators.

Perceptions of college students in consuming whole grain foods made with Brewers' Spent Grain.

One-third of all food produced for human consumption is wasted producing landfill accumulation and greenhouse gas emissions. Brewers' Spent Grains (BSGs) are the leftover grains from beer production, and each year approximately 30 million tons of BSG is generated globally by the brewing industry. Reclaiming BSG as a potential human food source is an opportunity for reducing food waste in the food supply chain. Six focus groups were conducted using 37 college students to determine their consumption of whole grains, perceptions of whole grains versus refined grains, and interest in or barriers related to consuming and purchasing foods made with BSG. Focus groups were transcribed verbatim and analyzed using constant comparative analysis to identify themes and discover relationships among the study aims. Thirteen themes emerged from focus group discussions with Concept of Health, Sensory, and Experience with BSG representing the top three discussed. Participants believed whole grains are healthier and contain more nutrients than refined grains. Most participants enjoyed the BSG foods provided; however, some noted a darker appearance and lingering fiber particles or aftertaste. Findings indicate participants who are hereditary whole grain consumers are acculturated to whole grain sensory attributes and nutritional benefits and would be more receptive to consuming BSG foods in future studies. We concluded most focus group participants were open to tasting BSG foods, but hereditary whole grain consumers should be the target consumer audience, and educating consumers on sensory attributes, potential health benefits, and environmental benefits is necessary to overcome the barriers associated with BSG.

Acceptance of two US Department of Agriculture commodity whole-grain products: a school-based study in Texas and Minnesota.

Whole-grain intake among children and adolescents is below national recommendations, prompting efforts to increase intake in schools. The purpose of this study was to compare the acceptance of whole-grain pancakes and tortillas to refined grain counterparts when served as part of the school meal. Data were collected at 10 schools in Minnesota and seven schools in Texas during the Spring and Fall semesters of 2009. Three pancake and two tortilla products of varying red or white whole-wheat flour content were each served an average of four times per school. Aggregate plate waste was collected and percent consumption used to assess acceptance. Students rated each product on overall liking, taste, color, and softness on 5-point (elementary schools) or 9-point hedonic scales (middle and high schools). Analysis of covariance was used to compare intake and rating scores of all products. For all children, intake of whole-grain products was substantial (percent consumption ranging from 67% to 75%). No differences were noted in consumption of whole-wheat pancakes compared to refined wheat pancakes, while consumption of whole-wheat tortillas was lower than refined products. In elementary schools, overall liking scores of pancakes made with red whole-wheat and both types of whole-wheat tortillas were lower than refined products. However, in middle and high schools, overall liking scores of 100% red whole-wheat pancakes and 66% white whole-wheat tortillas were similar to refined products. Substituting refined grain with whole-grain options represents a viable approach to increasing consumption of whole-grain products in schools.

Gender and ethnic differences in hand hygiene practices among college students.

BACKGROUND: Poor hand hygiene on college campuses can be improved by promoting handwashing behavior. This observational study was conducted to evaluate gender and race/ethnic differences in hand hygiene practices among college students. METHODS: Hand hygiene practices in college students were evaluated in 4 settings (soap and water; soap and water and visual prompts; soap and water and hand sanitizers; and soap and water, hand sanitizers, and visual prompts). The degree of hand hygiene (ie, adequate handwashing time, use of hand sanitizer, and hand-drying method) also was evaluated at various locations on campus. RESULTS: Overall, 72.9% of students washed their hands, 58.3% practiced hand hygiene (using either soap or hand sanitizer), and 26.1% washed their hands adequately. Hand sanitizer use was low when students were given the option, and paper towel was the most common hand-drying method. In general, hand hygiene practices were better in academic buildings than in the student recreation center. Visual prompts improved handwashing behavior only among students in the "other" ethnic category, but not by gender. CONCLUSIONS: Handwashing is the most effective way of preventing the spread of infectious diseases, and our findings have implications for the design of effective hand hygiene education programs in college students.
