“…Expecting a more positive affective effect from having a sufficient vegetable intake will contribute to progression to the M stage, as this effect increases the motivation of a subject to improve vegetable intake. As mentioned above, subjects in the A/M stage in the LPG had high scores in self-efficacy and affective attitude, which suggests that, compared to other factors, self-efficacy and affective attitude can be major influencing factors for increasing vegetable intake in adolescents, which has also been shown in other studies [ 11 13 , 22 ]. In addition, Van Duyn et al [ 23 ] reported that self-efficacy and affective attitudes were the most important factors in increasing the consumption of vegetables and fruit.…”

“…Questions aimed at evaluating the stages of behavioral changes related to vegetable intake were designed based on previous studies [ 13 18 ]. The first question was “Do you eat various kinds of vegetables?.” Subjects who responded “No” were questioned further, as follows; those who responded “No, I do not intend to eat various kinds of vegetables” to the question “Do you intend to eat various kinds of vegetables from now on?” were classified as PC, while those who responded “No, but I am planning on eating various kinds of vegetables in the near future (within six months)” were classified as C, and those who responded “Yes, I will eat various kinds of vegetables very soon (within one or two months)” were classified as P.…”

“…Despite this need and the importance of nutrition education to promote vegetable intake, only 21.3% of adolescents received nutrition education or counseling in 2015; however, 44.8% of children aged 6-11 years received such information [ 6 ]. In Korea, the factors regarding vegetable consumption in school-age children and adults has been previously reported [ 11 12 13 ], and self-efficacy has been proposed as a significant factor that could increase the vegetable consumption of those subjects [ 11 13 ]. However, there is a lack of studies with a psychological perspective that are based on nutrition education theory and that consider factors that influence adolescents' vegetable intake.…”

BACKGROUND/OBJECTIVESDespite the importance of consuming sufficient amounts of vegetables, daily vegetable intake among adolescents in Korea is lower than the current dietary recommendation. The objective of this study was to examine determinants affecting vegetable preference in order to suggest a stage-tailored education strategy that can promote vegetable consumption in adolescents.SUBJECTS/METHODSAdolescents (n = 400, aged 16-17 years) from two high schools participated in a cross-sectional study. Survey variables were vegetable preference, the social cognitive theory (SCT) and stages of change (SOC) constructs. Based on vegetable preference, subjects were classified into two groups: a low-preference group (LPG) and a high-preference group (HPG). SOC was subdivided into pre-action and action/maintenance stages. To compare SCT components and SOC related to vegetable preference, chi-squared and t-tests, along with stepwise multiple-regression analysis, were applied.RESULTSIn the LPG, a similar number of subjects were classified into each stage. Significant differences in self-efficacy, affective attitudes, and vegetable accessibility at home and school were detected among the stages. Subjects in the HPG were mainly at the maintenance stage (81%), and there were significant differences among the stages regarding self-efficacy, affective attitudes, and parenting practice. In the predictions of vegetable preference, self-efficacy and parenting practice had a significant effect in the “pre-action” stage. In the action/maintenance stage, outcome expectation, affective attitudes, and vegetable accessibility at school had significant predictive value. In predicting the vegetable preference for all subjects, 42.8% of the predictive variance was accounted for by affective attitudes, self-efficacy, and vegetable accessibility at school.CONCLUSIONThe study revealed that different determinants affect adolescent vegetable preference in each stage. Self-efficacy and affective attitudes are important determinants affecting vegetable preference. Additionally, school-based nutrition intervention that focuses on enhancing affective attitudes, self-efficacy, and vegetable exposure may constitute an effective education strategy for promoting vegetable consumption among adolescents.

“…Items for assessment of beliefs regarding nutrition label use (i.e., behavioral beliefs) were developed based on responses from pilot study and previous studies [ 24 , 25 ]. These included health and nutritional benefits (e.g., selecting healthy foods, not having foods high in fat or sodium, disease prevention, calorie control, and obesity prevention), practical benefits (e.g., making me eat adequate amount of foods, comparison of foods in food selection, helping others to select good foods), and disadvantages of nutrition label use (e.g., not eating favorite foods, spending time for food selection, cost, restrictions in food choices).…”

BACKGROUND/OBJECTIVESUse of nutrition labels in food selection is recommended for consumers. The aim of this study is to examine factors, mainly beliefs explaining nutrition label use in female college students based on the Theory of Planned Behavior (TPB).SUBJECTS/METHODSThe subjects were female college students from a university in Seoul, Korea. The survey questionnaire was composed of items examining general characteristics, nutrition label use, behavioral beliefs, normative beliefs, corresponding motivation to comply, and control beliefs. The subjects (n = 300) responded to the questionnaire by self-report, and data from 275 students were analyzed using t-test or χ2-test.RESULTSThe results showed that 37.8% of subjects were nutrition label users. Three out of 15 behavioral beliefs differed significantly by nutrition label use. Nutrition label users agreed more strongly on the benefits of using nutrition labels including 'comparing and selecting better foods' (P < 0.001), 'selecting healthy foods' (P < 0.05). The negative belief of 'annoying' was stronger in non-users than in users (P < 0.001). Three out of 7 sources (parents, siblings, best friend) were important in nutrition label use. Twelve out of 15 control beliefs differed significantly by nutrition label use. These included beliefs regarding constraints of using nutrition labels (e.g., time, spending money for healthy foods) and lack of nutrition knowledge (P < 0.001). Perceived confidence in understanding and applying the specifics of nutrition labels in food selection was also significantly related to nutrition label use (P < 0.001).CONCLUSIONSThis study found that the beliefs, especially control beliefs, suggested in the TPB were important in explaining nutrition label use. To promote nutrition label use, nutrition education might focus on increasing perceived control over constraints of using nutrition labels, acquiring skills for checking nutrition labels, as well as the benefits of using nutrition labels and receiving support from significant others for nutrition label use.

BackgroundThe importance of bone health is emphasized throughout the life cycle. Young adults have problems with bone health due to irregular lifestyle and unbalanced diet, but studies related to them are insufficient. The purpose of this study was to measure the bone mineral density (BMD) of college students and to analyze the differences in BMD according to lifestyle.MethodsBMD was measured by bone ultrasound in 161 male and female college students. The questionnaire was surveyed about lifestyle, eating habits, and nutrient intake status.ResultsOsteopenia was 8.8% in male and 10.8% in female. The body fat percentage of female was significantly higher than male. Male college students, smoking, fast food consumption, and overeating rate were significantly higher than female. Nutrient intake was not significantly different between male and female students. But energy and vitamin A and C levels were inadequate, and protein and sodium intake was excessive compared with the recommended nutrient intake for Koreans. BMD was significantly lowest in male who often intake fast food than male who did not intake at all or intake sometimes. Female who often intake fast food had significantly lower BMD than female who did not eat at all.ConclusionsCollege students have different BMDs according to lifestyle. There was a difference in BMD according to smoking and fast food consumption.
