Chronic disease risk typologies among young adults in community college

Objectives: To address chronic disease risk holistically from a behavioral perspective, insights are needed to refine understanding of the covariance of key health behaviors. This study aims to identify distinct typologies of young adults based on 4 modifiable risk factors of chronic disease using a latent class analysis approach, and to describe patterns of class membership based on demographic characteristics, living arrangements, and weight. Methods: Overall, 441 young adults aged 18-35 attending community colleges in the Minnesota Twin Cities area completed a baseline questionnaire for the Choosing Healthy Options in College Environments and Settings study, a RCT. Behavioral items were used to create indicators for latent classes, and individuals were classified using maximum-probability assignment. Results: Three latent classes were identified: ‘active, binge-drinkers with a healthy dietary intake’ (13.1%); ‘non-active, moderate-smokers and non-drinkers with poor dietary intake’ (38.2%); ‘moderately active, non-smokers and non-drinkers with moderately healthy dietary intake’ (48.7%). Classes exhibited unique demographic and weight-related profiles. Conclusions: This study may contribute to the literature on health behaviors among young adults and provides evidence that there are weight and age differences among subgroups. Understanding how behaviors cluster is important for identifying groups for targeted interventions in community colleges

Identifying and describing segments of office workers by activity patterns: Associations with demographic characteristics and objectively measured physical activity

Purpose - The purpose of this paper is to identify and characterize patterns of physical activity among office workers employed in largely sedentary occupations at a major health insurer located in the Southeastern USA. Design/methodology/approach - The authors used latent class analysis to identify segments of office workers (n=239) based on their self-reported activities of daily living and exercise behaviors. The authors examined the association of demographic characteristics with segment membership, and differences in accelerometer-measured weekly minutes of light and moderate-vigorous physical activity across segments. Findings - The authors identified two segments and labeled them "exerciser" and "non-exerciser." Being female was associated with lower odds of membership in the "exerciser" segment (OR=0.18; 95% CI=0.06, 0.52), while those with at least a bachelor's degree were more likely to be in the "exerciser" segment (OR=2.12; 95% CI=1.02, 4.40). Mean minutes of moderate-vigorous physical activity per week were greater for the "exerciser" segment than the "non-exerciser" segment. Practical implications - Based on this sample, the authors found that office workers in sedentary occupations were roughly equally divided and distinguished by their engagement in exercise-type behaviors. The findings underscore the need for innovative workplace programming that enhances activity opportunities particularly for those that are not likely to exercise. Originality/value - A scarcity of research on activity patterns among office workers inhibits development of targeted worksite activity programming. The present research reveals two segments of workers with regard to their activity patterns and suggests ways for worksites to meet their unique needs

Using the theory of planned behavior to explain intention to eat a healthful diet among Southeastern United States office workers

Purpose: This study aims to test the utility of the theory of planned behavior (TPB) for explaining intention to eat a healthful diet in a sample of Southeastern US office workers. Design/methodology/approach: Participants in a worksite nutrition study (n = 357) were invited to complete an online questionnaire including measures of TPB constructs at baseline. The questionnaire included valid and reliable measures of TPB constructs: behavioral beliefs, normative beliefs, control beliefs, attitudes toward behavior, subjective norm, perceived behavioral control and intention. Data were collected from 217 participants (60.8 per cent response rate). Confirmatory factor analysis and structural equation modeling were conducted to test the hypothesized TPB model. Findings: The model fit was satisfactory (χ2 = p < 0.0001, RMSEA = 0.06, CFI = 0.91, TLI = 0.90, SRMR = 0.09). All structural relationships between TPB constructs were statistically significant in the hypothesized direction (p < 0.05). Attitude toward behavior, subjective norm and perceived behavioral control were positively associated with intention (R2 = 0.56). Of all TPB constructs, the influence of perceived behavioral control on intention was the strongest (β = 0.62, p < 0.001). Originality/value: Based on this sample of Southeastern US office workers, TPB-based interventions may improve intention to eat a healthful diet. Interventions that strengthen perceived control over internal and external factors that inhibit healthful eating may be particularly effective in positively affecting intention to eat a healthful diet, and subsequent food intake

Nurturing Children's Healthy Eating: Position statement

The relationship between eating a healthy diet and positive health outcomes is well known; nurturing healthy eating among children therefore has the potential to improve public health. A healthy diet occurs when one''s usual eating patterns include adequate nutrient intake and sufficient, but not excessive, energy intake to meet the energy needs of the individual. However, many parents struggle to establish healthy eating patterns in their children due to the pressures of modern life. Moreover, healthcare providers often do not have the time or the guidance they need to empower parents to establish healthy eating practices in their children. Based on existing evidence from epidemiologic and intervention research, the Nurturing Children''s Healthy Eating collaboration, established by Danone Institute International, has identified four key themes that encourage and support healthy eating practices among children in the modern Western world. The first — positive parental feeding — explores how parenting practices and styles, such as avoiding food restriction, allowing children to make their own food choices, and encouraging children to self-limit their portion sizes, can influence children''s dietary intake. The second — eating together — highlights the link between eating socialization through regular family meals and healthful diet among children. The third — a healthy home food environment — explores the impact on eating practices of family resources, food availability/accessibility, parental modeling, and cues for eating. The fourth — the pleasure of eating — associates children''s healthy eating with pleasure through repeated exposure to healthful foods, enjoyable social meals, and enhancement of the cognitive qualities (e.g. thoughts or ideas) of healthful foods. This paper reviews the evidence leading to the characterization of these nurturing themes, and ways in which recommendations might be implemented in the home

Cooking Matters for Kids Improves Attitudes and Self-Efficacy Related to Healthy Eating and Cooking

Objective: To assess changes in self-efficacy and attitudes related to healthy eating and cooking in Cooking Matters for Kids participants. Design: Prepost study design. Setting: Cooking Matters for Kids programs offered by 35 organizations. Participants: Predominantly third- to fifth-grade children participating in Cooking Matters for Kids lessons during fiscal years 2012–17 with matched presurvey and postsurveys (n = 18,113). Intervention(s): Cooking Matters for Kids consists of six 2-hour experiential nutrition and cooking education lessons. Main Outcome Measure(s): Self-efficacy related to healthy eating and cooking and attitudes toward healthy foods assessed through the Cooking Matters for Kids Participant Survey. Analysis: Changes from the presurvey to postsurvey were assessed using mixed models and repeated measures ordered logistic regression accounting for clustering by course. Effect sizes were calculated using Cohen d for repeated measures. A Bonferroni adjustment was used to correct for multiple comparisons (α = 0.025). Results: Both overall and individual self-efficacy and attitude scores improved from presurvey to postsurvey (P < 0.0001). The effect sizes were 0.35 for overall self-efficacy score and 0.17 for overall attitude score. Conclusions and Implications: Participation in Cooking Matters for Kids was associated with improvements in self-efficacy and attitudes related to healthy eating and cooking

College student motivations for and perceived impacts of volunteering with a nutrition and cooking education program for children

To assess among college students their motivations for and perceived impacts of volunteering with Cooking Matters for Kids as part of No Kid Hungry NC. Seventeen college student volunteers responded to an online survey questionnaire assessing their motivations for volunteering and how they were impacted by their experiences. Motivational functions for volunteering (values, understanding, social, career, protective, enhancement) were assessed using the Volunteer Functions Inventory. The strongest motivational functions for volunteering were values and understanding. Students were also strongly motivated to volunteer related to the areas specifically addressed by the program (i.e., nutrition, public health, working with children). Perceived impacts of volunteering included being more comfortable working with children, improving knowledge/skills, gaining experience related to their future career, and having fun. Volunteering with Cooking Matters for Kids benefited college students. Issues addressed by the program and the desire to gain experience motivated students to volunteer

Mission Analysis and Aircraft Sizing of a Hybrid-Electric Regional Aircraft

The purpose of this study was to explore advanced airframe and propulsion technologies for a small regional transport aircraft concept (approximately 50 passengers), with the goal of creating a conceptual design that delivers significant cost and performance advantages over current aircraft in that class. In turn, this could encourage airlines to open up new markets, reestablish service at smaller airports, and increase mobility and connectivity for all passengers. To meet these study goals, hybrid-electric propulsion was analyzed as the primary enabling technology. The advanced regional aircraft is analyzed with four levels of electrification, 0 percent electric with 100 percent conventional, 25 percent electric with 75 percent conventional, 50 percent electric with 50 percent conventional, and 75 percent electric with 25 percent conventional for comparison purposes. Engine models were developed to represent projected future turboprop engine performance with advanced technology and estimates of the engine weights and flowpath dimensions were developed. A low-order multi-disciplinary optimization (MDO) environment was created that could capture the unique features of parallel hybrid-electric aircraft. It is determined that at the size and range of the advanced turboprop: The battery specific energy must be 750 watt-hours per kilogram or greater for the total energy to be less than for a conventional aircraft. A hybrid vehicle would likely not be economically feasible with a battery specific energy of 500 or 750 watt-hours per kilogram based on the higher gross weight, operating empty weight, and energy costs compared to a conventional turboprop. The battery specific energy would need to reach 1000 watt-hours per kilogram by 2030 to make the electrification of its propulsion an economically feasible option. A shorter range and/or an altered propulsion-airframe integration could provide more favorable results
