Nutrition knowledge,outcome expectations,self-efficacy,and eating behaviors by calcium intake level in Korean female college students

BACKGROUND/OBJECTIVES

Calcium is important but deficient in diets of young adult women. This study aimed to examine if cognitive factors and eating behaviors differ according to calcium intake based on the Social Cognitive Theory.

SUBJECTS/METHODS

Subjects were female college students in Seoul, Korea. Three hundred students completed the questionnaire regarding calcium intake, nutrition knowledge, outcome expectations, self-efficacy and eating behaviors. Data on 240 students were analyzed using t-test or χ²-test. Subjects were categorized into two groups, high calcium intake (HC, ≥ 650 mg/day) and low calcium intake (LC, < 650 mg/day), according to recommended intakes of calcium for women aged 19-29 years.

RESULTS

The LC group constituted 77.9% of total subjects. Nutrition knowledge was not different according to calcium intake. Three out of 12 outcome expectations items were significantly different between the HC and LC groups. Subjects in the HC group agreed more strongly with the practical benefits of consuming calcium-rich foods, including ''taste'' (P < 0.01) and ''going well with other snacks'' (P < 0.05), compared to those in the LC group. Negative expectations of ''indigestion'' were stronger in the LC group than HC group (P < 0.001). Among self-efficacy items, perceived ability of ''eating dairy foods for snacks'' (P < 0.001), ''eating dairy foods every day'' (P < 0.01), and ''eating calcium-rich side dishes at meals'' (P < 0.05) differed significantly between the HC and LC groups. Eating behaviors including more frequent consumption of dairy foods, fruits or fruit juice (P < 0.001), anchovy, seaweeds, green vegetables, protein-rich foods (P < 0.05), and less frequent consumption of sweets or soft drinks (P < 0.01) were significantly related to calcium intake.

CONCLUSIONS

This study found that outcome expectations, self-efficacy in consuming calcium-rich foods, and eating behaviors are important in explaining calcium intake. Nutrition education needs to address practical benefits, reduce negative expectations of calcium-rich foods, increase self-efficacy, and modify eating behaviors contributing to calcium intake.     

Relationships of adolescent's dietary habits with personality traits and food neophobia according to family meal frequency

BACKGROUND

A higher frequency of family meals is associated with good dietary habits in young people. This study focused on the relationships of family meal frequency with food neophobia and personality traits in adolescents.

SUBJECTS/METHOD

For this purpose, we administered a survey to 495 middle school students in Seoul metropolitan city, after which the data were analyzed using the SPSS (18.0) program. Pearson correlation was used to determine the relationships among dietary habits, personality traits, and food neophobia according to frequency of family meals.

RESULTS

Dietary habits, personality traits, and food neophobia all showed significant differences according to the frequency of family meals. Further, eating regular family meals was associated with good dietary habits (P < 0.001) and was linked with improved extraversion, agreeableness, conscientiousness, emotional stability, and openness/intellect (P < 0.001). On the other hand, it showed a negative relationship with food neophobia (P < 0.001). The relationship between dietary habits and food neophobia showed a negative correlation (P < 0.01). The relationship between dietary habits and personality traits showed a positive correlation (P < 0.01). Lastly, the relationship between personality traits and food neophobia showed a negative correlation (P < 0.01).

CONCLUSION

Based on the results of the study, the frequency of family meals affects dietary habits, personality traits, and food neophobia in adolescents.     

Weight misperception and its association with dieting methods and eating behaviors in South Korean adolescents

BACKGROUND/OBJECTIVES

There is little information on the association between weight misperception and eating behavior in Korean adolescents. Therefore, we investigated the association of food intake habits and dieting method and disturbed eating behavior (DEB) in relation to weight misperception.

SUBJECTS/METHODS

Data was collected by using a nationwide online panel survey from 6,943 adolescents enrolled in middle/high school. DEB was measured with the Eating Attitudes Test (EAT-26) and those who scored ≥ 20 on the EAT-26 were considered to have eating disorder. Logistic regressions were conducted to examine the association between weight misperception based on self-reported weight status and dieting method and eating behaviors.

RESULTS

The proportion of weight underestimation was 23.5% and that of overestimation was 24.0%. Weight overestimating girls were more likely to engage in various unhealthy dieting practices (OR = 1.69 for fasting; OR = 1.88 for laxative or diuretic use; OR = 2.05 for self-induced vomiting after meals; P < 0.05). Moreover, there was a strong association between overestimation and undesirable eating behaviors, especially among girls, e.g.: having breakfast (OR = 0.85), high consumption of fast foods (OR = 1.28) and regular sodas (OR = 1.39), but not among boys. In both genders, weight overestimation appears to be a major risk factor for DEB (OR = 1.34 for boys and OR = 1.41 for girls; P < 0.05).

CONSLUSIONS

Weight overestimation is associated with unhealthy weight control practices and eating behaviors. We particularly found a significant association between weight overestimation and DEB among nationwide Korean adolescents.     

Comparison of sodium content of workplace and homemade meals through chemical analysis and salinity measurements

BACKGROUND/OBJECTIVES

Most Koreans consume nearly 70-80% of the total sodium through their dishes. The use of a salinometer to measure salinity is recommended to help individuals control their sodium intake. The purpose of this study was to compare sodium content through chemical analysis and salinity measurement in foods served by industry foodservice operations and homemade meals.

MATERIALS/METHODS

Workplace and homemade meals consumed by employees in 15 cafeterias located in 8 districts in Daegu were collected and the sodium content was measured through chemical analysis and salinity measurements and then compared. The foods were categorized into 9 types of menus with 103 workplace meals and 337 homemade meals.

RESULTS

Workplace meals did not differ significantly in terms of sodium content per 100 g of food but had higher sodium content via chemical analysis in roasted foods per portion. Homemade meals had higher broth salt content and higher salt content by chemical analysis per 100 g of roasted foods and hard-boiled foods. One-dish workplace meals had higher salinity (P < 0.05), while homemade broths and stews had higher sodium content (P < 0.05 and P < 0.01, respectively). The sodium content per 100 g of foods was higher in one-dish workplace meals (P < 0.05) and in homemade broths and stews (P < 0.01 and P < 0.05, respectively).

CONCLUSIONS

The use of a salinometer may be recommended to estimate the sodium content in foods and control one''s sodium intake within the daily intake target as a way to promote cooking bland foods at home. However, estimated and actual measured values may differ.     

High tendency to the substantial concern on body shape and eating disorders risk of the students majoring Nutrition or Sport Sciences

BACKGROUND/OBJECTIVES

Studies have indicated that university students majoring in nutrition and dietetics or sport sciences may have more obsessions associated with eating attitudes and body shape perception compared to other disciplines i.e. social sciences. Therefore, this study aimed to assess and compare the risk of eating disorders and body shape perception.

MATERIALS/METHODS

Data was collected from 773 undergraduate students at the Departments of Nutrition and Dietetics (NDD) (n = 254), Physical Education and Sports (PESD) (n = 263), and Social Sciences (SOC) (n = 256).A socio-demographic and personal information questionnaire, Eating Attitudes Test (EAT-40), Body Shape Questionnaire (BSQ-34), Perceived Figure Rating Scale (FRS) were applied; and body weights and heights were measured.

RESULTS

Mean EAT-40 scores showed that, both male and female students of PESD had the highest scores (17.4 ± 11.6) compared with NDD (14.3 ± 8.3) and SOC (13.0 ± 6.2) (P < 0.05). According to EAT-40 classification, high risk in abnormal eating behavior was more in PESD (10.7%) compared to NDD (2.9%) and SOC (0.4%) students (P < 0.05). Students of PESD, who skipped meal, had higher tendency to the risk of eating disorders (P < 0.05). In parallel, body shape perception was found to be marked with higher scores in NDD (72.0 ± 28.7) and PESD (71.5 ± 32.8) compared with SOC (64.2 ± 27.5) students (P < 0.05). Considering BSQ-34 classification, high concern (moderate and marked) for body shape were more in PESD (7.4 %) compared to NDD (5.2%) and SOC (1.9%) students (P < 0.05). The body size judgement via obtained by the FRS scale were generally correlated with BMI. The Body Mass Index levels were in normal range (Mean BMI: 21.9 ± 2.8 kg/m²) and generally consistent with FRS data.

CONCLUSIONS

Tendency to the abnormal eating behavior and substantial body shape perception were higher in PESD students who have more concern on body shape and were not well-educated about nutrition. In conclusion, substantial concern on physical appearance might affect eating behavior disorders in PESD students.     

Evaluation of diet quality and its associated factors among adolescents in Kuala Lumpur,Malaysia

BACKGROUND/OBJECTIVES

This study aims to determine contribution of meal frequency, self-efficacy for healthy eating, and availability of healthy foods towards diet quality of adolescents in Kuala Lumpur, Malaysia.

SUBJECTS/METHODS

This study was conducted among 373 adolescents aged from 13 to 16 years old. Diet quality of the respondents was assessed using the Healthy Eating Index for Malaysians. Meal frequency, self-efficacy for healthy eating, and availability of healthy foods were assessed through the Eating Behaviours Questionnaire (EBQ), self-efficacy for healthy eating scale, and availability of healthy foods scale, respectively.

RESULTS

The majority of the respondents (80.7%) were at risk of poor diet quality. Males (mean = 34.2 ± 8.2%) had poorer diet quality than females (mean = 39.9 ± 9.0%) (t = -5.941, P < 0.05). Malay respondents (mean = 36.9 ± 8.7%) had poorer diet quality than Indian respondents (mean = 41.3 ± 10.0%) (F = 2.762, P < 0.05). Age (r = 0.123, P < 0.05), self-efficacy for healthy eating (r = 0.129, P < 0.05), and availability of healthy foods (r = 0.159, P < 0.05) were positively correlated with the diet quality of the respondents. However, meal frequency was not correlated with the diet quality of the respondents. Multiple linear regression analysis showed that being a male, being a Malay, low self-efficacy for healthy eating, and low availability of healthy foods contributed significantly towards poor diet quality among respondents.

CONCLUSIONS

In short, sex, ethnicity, self-efficacy for healthy eating, and availability of healthy foods were associated with diet quality among adolescents. Health practitioners should take into consideration of differences in sex and ethnicity during implementation of nutrition-related intervention programs. Self-efficacy for healthy eating and availability of healthy foods should be included as important components in improving diet quality of adolescents.     

A Study of Predictive Factors Affecting Health: Promoting Behaviors of North Korean Adolescent Refugees

Objectives:

The present study aimed to analyze the factors that could affect the health-promoting behaviors of North Korean adolescent refugees residing in South Korea.

Methods:

Questions about their sociodemographic variables, subjective health status, healthy living habits, and health-promoting behaviors were asked.

Results:

Statistically significant differences were found in religion (t=2.30, p<0.05), having family members in South Korea (t=2.02, p<0.05), and subjective health status (t=4.96, p<0.01). Scores on health-responsible behaviors were higher with higher age (t=2.90, p<0.01) and for subjects without family or friends (t=2.43, p<0.05). Higher physical-activity behaviors were observed in males (t=3.32, p<0.01), in those with better subjective health status (t=3.46, p<0.05) and lower body mas index (t=3.48, p<0.05), and in smokers (t=3.17, p<0.01). Nutritional behaviors were higher in those who followed a religion (t=2.17, p<0.05). Spiritual growth behaviors were higher in those who followed a religion (t=4.21, p<0.001), had no family in South Korea (t=2.04, p<0.05), and had higher subjective health status (t=5.74, p<0.01). Scores on interpersonal relationships and stress-management behaviors were higher for those with higher subjective health status. A multiple regression analysis showed greater effects on health-promoting behaviors when subjective health status was better. Older people and non-smokers exhibited more health-responsible behaviors, while more physical-activity behaviors and spiritual growth activities were observed when subjective health status was better. Interpersonal relationship behaviors had positive effects on those with good subjective heath status and on non-smokers.

Conclusions:

Based on the results of the current study, an alternative was suggested for promoting health in North Korean adolescent refugees.     

Acculturation and changes in dietary behavior and anthropometric measures among Chinese international students in South Korea

BACKGROUND/OBJECTIVES

International students face dissimilar food environments, which could lead to changes in dietary behaviors and anthropometric characteristics between before and after migration. We sought to examine the risk factors, including dietary behaviors, acculturation, and demographic characteristics, related to overweight subjects residing in South Korea.

SUBJECTS/METHODS

We conducted a cross-sectional study, collecting data from 142 Chinese international students (63 males, 79 females) in 2013.

RESULTS

The mean age of the subjects was 25.4 years, and almost half of them immigrated to South Korea to earn a master''s degree or doctoral degree (n = 70, 49.3%). Chinese international students showed an increase in skipping meals and eating speed, but a decrease in the frequency of fruit and vegetable consumption in South Korea compared to when they lived in China. We found a statistically significant increase in weight (69.4 → 73.9 kg) and BMI (22.4 → 23.8 kg/m²) for male subjects (P < 0.001) but no change for female subjects. We also found that overweight subjects were more likely to be highly acculturated and male compared with normal-weight subjects.

CONCLUSION

Among Chinese international students living in South Korea, male and more highly acculturated subjects are more vulnerable to weight gain. This study provides useful information to design tailored nutrition intervention programs for Chinese international students.     

Peer Reviewed: Dietary Behaviors Associated With Fruit and Vegetable Consumption, Marion County, Indiana, 2005

Introduction

Eating inadequate amounts of fruits and vegetables is associated with diminished health, and most Americans fall short of the Centers for Disease Control and Prevention''s recommendation to eat at least 2 servings of fruit and 3 servings of vegetables each day. This study assessed behaviors associated with fruit and vegetable consumption in adults.

Methods

A cross-sectional, random-digit–dialed telephone survey of 4,784 adults living in Marion County (Indianapolis), Indiana, measured demographic characteristics, personal health data, food consumption, food label use, and other eating habits. Multivariate logistic regressions were used to assess the association between selected dietary behaviors and fruit and vegetable consumption, controlling for demographic characteristics.

Results

Behaviors associated with adequate versus inadequate consumption of fruits and vegetables were frequent snacking on healthy foods (odds ratio [OR], 2.54), eating meals at home (OR, 2.09), using nutrition labels when making purchases (OR, 1.52), and using "heart healthy" symbols and other food information labels when ordering from restaurants (OR, 1.41). Frequent red meat consumption was negatively associated with adequate consumption of fruits and vegetables (OR, 0.64).

Conclusions

Healthful snacking, food label use, and eating meals prepared at home may improve dietary quality. Our measure of adequacy may also be useful in future studies assessing dietary behavior and diet composition.     

Evaluation of dietary behaviors of preschool children in Seoul and Gyeonggi-do associated with the level of parents' health consciousness: using nutrition quotient for preschoolers (NQ-P)

BACKGROUND/OBJECTIVESThis study aimed to assess the dietary behaviors of preschool children using the nutrition quotient for preschoolers (NQ-P) and analyzed the difference in the scores of the children''s dietary behaviors in regards to the parents'' health consciousness.SUBJECTS/METHODSThe subjects were 257 children aged 3–5 years and their parents residing in Seoul and Gyeonggi-do, South Korea. The questionnaire is composed of demographic characteristics, the NQ-P questions, and health consciousness. All data were statistically analyzed by SPSS program (ver. 25.0) and the statistical differences in variables were evaluated by χ² test, Fisher''s exact test, t-test, 1-way analysis of variance and Tukey''s multiple comparison test.RESULTSThere was a significant difference on the intake frequency of processed meat by region and fast foods by age, region, and weight status (P < 0.05). There was also a significant difference in not moving around while eating by weight status and parents'' effort to have healthy eating habits by sex (P < 0.05). The mean score of NQ-P of the total subjects was 59.47, which was within the medium-low grade. The mean score of balance was 61.62, and the boys were significantly higher than girls (P < 0.05). As the age of children increased, the mean score of the moderation was significantly decreased (P < 0.05). The scores of NQ-P (P < 0.05), balance (P < 0.01), and environment (P < 0.05) were significantly higher in the high group of parents'' health consciousness than the low group.CONCLUSIONSAccording to the results of the evaluation by NQ-P, the dietary behaviors of preschoolers residing in Seoul and Gyeonggi-do need to be improved. For improving their eating behavior and nutritional health status, parents and children need customized nutrition education programs based on sex, age, region and weight status of preschool children as well as the degree of parents'' health consciousness.     

Association between family structure and food group intake in children

BACKGROUNDS/OBJECTOVES

Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea.

SUBJECTS/METHODS

A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children''s family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children''s food group intake, scores of individual food groups (''Grains'', ''Meat, Fish, Eggs and Beans'', ''Vegetables'', ''Fruits'' and ''Milk and Dairy products'') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). ''Food group mean score'' was obtained by calculating the average of five food group scores.

RESULTS

After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in ''Fruits'' (P < 0.01), ''Milk and Dairy products'' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with ''Fruits,'' ''Milk and Dairy products'' score and mean scores of food group scores.

CONCLUSIONS

These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.     

Recreational Screen-Time Among Chinese Adolescents: A Cross-Sectional Study

Background

Rapid urbanization in China has led to a proliferation of electronic entertainment media among youth. Prolonged screen time (ST; includes watching television and playing on computers, video game consoles, or mobile phones) is linked to poor health profiles. The aim of this study was to report recreational ST behaviors and ST correlates among Chinese adolescents living in two regions with different degrees of urbanization.

Methods

A cross-sectional, school-based survey (n = 3461 adolescents; aged 12–14 years old) living in inner-city Shanghai and a peri-urban region of Hangzhou. Students completed a questionnaire including family characteristics, daily ST, and information on family environment related to screen use. Recreational ST was categorized into two groups according to recommendations by the American Academy of Pediatrics (< or ≥2 h/day). Parents reported their own ST and also reported educational attainment as a proxy for socioeconomic status.

Results

ST was higher among boys than girls and on weekends than weekdays. Peri-urban girls were more likely to exceed 2 h/day ST compared to inner-city girls on weekends. Having a father with no university degree, mother’s TV viewing ≥2 h/day, no ST rules at home, and eating meals in front of the TV were associated with higher ST on both weekdays and weekends, and regional differences were found for weekend ST.

Conclusions

TV viewing and playing on the computer were the most prevalent ST behaviors among Chinese adolescents. Mobile phone playing was less prevalent but persistent throughout the week. More population-level surveillance and research is needed to monitor the trends in ST behaviors and to better understand the characteristics of those who are at risk.Key words: screen time, adolescents, China, urban     

Physician Communication Regarding Prostate Cancer Screening: Analysis of Unannounced Standardized Patient Visits

PURPOSE

Prostate cancer screening with prostate-specific antigen (PSA) is a controversial issue. The present study aimed to explore physician behaviors during an unannounced standardized patient encounter that was part of a randomized controlled trial to educate physicians using a prostate cancer screening, interactive, Web-based module.

METHODS

Participants included 118 internal medicine and family medicine physicians from 5 health systems in California, in 2007–2008. Control physicians received usual education about prostate cancer screening (brochures from the Center for Disease Control and Prevention). Intervention physicians participated in the prostate cancer screening module. Within 3 months, all physicians saw unannounced standardized patients who prompted prostate cancer screening discussions in clinic. The encounter was audio-recorded, and the recordings were transcribed. Authors analyzed physician behaviors around screening: (1) engagement after prompting, (2) degree of shared decision making, and (3) final recommendations for prostate cancer screening.

RESULTS

After prompting, 90% of physicians discussed prostate cancer screening. In comparison with control physicians, intervention physicians showed somewhat more shared decision making behaviors (intervention 14 items vs control 11 items, P <.05), were more likely to mention no screening as an option (intervention 63% vs control 26%, P <.05), to encourage patients to consider different screening options (intervention 62% vs control 39%, P <.05) and seeking input from others (intervention 25% vs control 7%, P<.05).

CONCLUSIONS

A brief Web-based interactive educational intervention can improve shared decision making, neutrality in recommendation, and reduce PSA test ordering. Engaging patients in discussion of the uses and limitations of tests with uncertain value can decrease utilization of the tests.     

Vital Signs: Sodium Intake Among U.S. School-Aged Children — 2009–2010

Background

A national health objective is to reduce average U.S. sodium intake to 2,300 mg daily to help prevent high blood pressure, a major cause of heart disease and stroke. Identifying common contributors to sodium intake among children can help reduction efforts.

Methods

Average sodium intake, sodium consumed per calorie, and proportions of sodium from food categories, place obtained, and eating occasion were estimated among 2,266 school-aged (6–18 years) participants in What We Eat in America, the dietary intake component of the National Health and Nutrition Examination Survey, 2009–2010.

Results

U.S. school-aged children consumed an estimated 3,279 mg of sodium daily with the highest total intake (3,672 mg/d) and intake per 1,000 kcal (1,681 mg) among high school–aged children. Forty-three percent of sodium came from 10 food categories: pizza, bread and rolls, cold cuts/cured meats, savory snacks, sandwiches, cheese, chicken patties/nuggets/tenders, pasta mixed dishes, Mexican mixed dishes, and soups. Sixty-five percent of sodium intake came from store foods, 13% from fast food/pizza restaurants, 5% from other restaurants, and 9% from school cafeteria foods. Among children aged 14–18 years, 16% of total sodium intake came from fast food/pizza restaurants versus 11% among those aged 6–10 years or 11–13 years (p<0.05). Among children who consumed a school meal on the day assessed, 26% of sodium intake came from school cafeteria foods. Thirty-nine percent of sodium was consumed at dinner, followed by lunch (29%), snacks (16%), and breakfast (15%).

Implications for Public Health Practice

Sodium intake among school-aged children is much higher than recommended. Multiple food categories, venues, meals, and snacks contribute to sodium intake among school-aged children supporting the importance of populationwide strategies to reduce sodium intake. New national nutrition standards are projected to reduce the sodium content of school meals by approximately 25%–50% by 2022. Based on this analysis, if there is no replacement from other sources, sodium intake among U.S. school-aged children will be reduced by an average of about 75–150 mg per day and about 220–440 mg on days children consume school meals.     

Perceived Relevance of Educative Information on Public (Skin) Health: A Cross-sectional Questionnaire Survey

Objectives

Unprotected leisure time exposure to ultraviolet radiation from the sun or artificial tanning beds is the most important environmental risk factor for melanoma, a malignant skin cancer with increasing incidences over the past decades. The aim of the present study was to assess the impact of skin health information provided by several sources and different publishing issues on knowledge, risk perception, and sun protective behavior of sunbathers.

Methods

A cross-sectional questionnaire survey was conducted among Austrian residents (n=563) spending leisure time outdoors in August 2010.

Results

Print media, television, and family were perceived as the most relevant sources of information on skin health, whereas the source physician was only ranked as fourth important source. Compared to other sources, information provided by doctors positively influenced participants'' knowledge on skin risk and sun protective behavior resulting in higher scores in the knowledge test (p=0.009), higher risk perception (p<0.001), and more sun protection (p<0.001).Regarding gender differences, internet was more often used by males as health information source, whereas females were more familiar with printed information material in general.

Conclusions

The results of this survey put emphasis on the demand for information provided by medical professionals in order to attain effective, long-lasting promotion of photoprotective habits.     

Taste education reduces food neophobia and increases willingness to try novel foods in school children

BACKGROUND/OBJECTIVES

This study measured the effects of a taste education program developed in Korea on food neophobia and willingness to try novel foods in school children.

SUBJECTS/METHODS

One-hundred and twenty school children (aged 7-9 years) residing in Seoul participated in 12 sessions of a taste education program for 3 months. The Korean taste education program was adapted from "Les classes du goût" by J. Puisais and modified to suit a Korean education environment. The study subjected school children to pre- and post-programs on food neophobia and willingness to try novel foods (WTNF), in addition to children''s food neophobia in their parents. A total of 101 survey data were analyzed using SPSS 18.0.

RESULTS

Regarding the effects of taste education, scores of food neophobia significantly decreased (P < 0.01) in the posttest, mean (m) score (4.10 ± 1.19) decreased compared to the pretest (4.39 ± 1.00), and WTNF significantly increased (P < 0.001) in the pretest (m) score (0.48 ± 0.33) compared to the pretest (0.32 ± 0.34). This result indicates verification of the study hypothesis.

CONCLUSIONS

Food neophobia scale (FNS), an index that measures personal food preference [1,2], showed a very weak correlation with behavioral willingness to taste novel foods (WTNF). Therefore, it is expected that the two scales measure different things. However, considering that the traits of food neophobia are not easily changed, the taste education program was administered in a remarkably effective manner.     

Peer Reviewed: Assessing Calcium Intake in Postmenopausal Women

Introduction

Because foods fortified with calcium are increasingly available, the calcium content of calcium-fortified foods may not be adequately captured in traditional assessments of dietary intake, such as dietary records analyzed with commercially available software. The primary objective of our study was to design and test a calcium-focused food frequency questionnaire (CFFFQ) including foods naturally rich in calcium and calcium-fortified foods. Secondary objectives were to review calcium sources and adequacy of intake in black and in white postmenopausal women.

Methods

We studied a convenience sample of 46 black and 139 white postmenopausal women (mean [SD] age 69.4 [5.8] years). Subjects completed a multiple-pass interview for 24-hour recall of foods eaten and the 46-item CFFFQ.

Results

The correlation between measures for total daily calcium intake was moderately strong (r = 0.53, P < .001). The CFFFQ estimated greater total daily calcium intake than did the 24-hour recall (mean [SD], 1,021 [624] mg/d vs 800 [433] mg/d, P < .001). As daily calcium intake increased, the 24-hour recall increasingly underreported calcium (r = 0.41, P < .001) compared with the CFFFQ. Cross-tabulation and Χ² analyses found that the CFFFQ had greater specificity for lower calcium intakes. For calcium classified by food groups, there was moderate correlation for dairy (r = 0.56, P < .001) and fruits (r = 0.43, P < .001). The CFFFQ overestimated mean total calcium compared with the 24-hour recall by 221 mg/d (P < .001), including within racial groups (195 mg/d for black women, P = .04, and 229 mg/d for white women, P < .001). Dairy was the primary calcium source for both groups (55% of intake for black women and 57% of intake for white women).

Conclusion

The CFFFQ can be used to identify postmenopausal women with inadequate calcium intakes (<800 mg/d) and to identify key sources of dietary calcium. Older black women consume less daily calcium than do older white women.     

Changes in Dietary Behavior Among Adolescents and Their Association With Government Nutrition Policies in Korea, 2005-2009

Objectives

This study was conducted to observe recent changes in adolescents'' dietary behavior and indirectly evaluate the effects of the government''s nutritional policies in Korea.

Methods

We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents''dietary behaviors during the same periods.

Results

The significant linear trends were observed in all dietary behaviors (p<0.05). Overall, all behaviors except the fruit intake rate were desirably changed during five years but undesirable changes were observed between 2008 and 2009 in all behaviors. Within those periods, several policies were implemented including ''Ban on carbonated-beverages in school'', ''Green Food Zone'', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn''t influence the prevalence of dietary behaviors because they were conducted to too limited persons. Polices on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn''t come to a conclusion because of too short period after full implementation.

Conclusions

Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.     

Psychosocial factors and eating behaviors according to the stages of change in nutrition management among elementary and middle school athletes

BACKGROUND/OBJECTIVESThis study examined the differences in psychosocial factors and eating behaviors by the stages of change (SOC) in nutrition management among elementary and middle school athletes.SUBJECTS/METHODSSubjects were young athletes recruited from the athletic clubs of 10 organizations. Subjects responded to a survey questionnaire, and data on 167 athletes were analyzed. Subjects were grouped into the pre-action or action stage in nutrition management. The χ² test, t-test, analysis of covariance, and correlation analysis were used in data analysis.RESULTSAthletes in the action stage (62.3%) compared to the pre-action stage, showed a higher self-efficacy (P < 0.01), and felt more confidence in performing specific eating behaviors (P < 0.05 to P < 0.01). Those in the action stage had more favorable beliefs regarding nutrition (P < 0.001) and agreed less strongly on the specific misconceptions/disadvantages of nutrition (P < 0.01) than those in the pre-action stage. Eating behaviors (P < 0.001) and subscales of the eating behaviors (P < 0.05 to P < 0.01) also differed significantly by the SOC group. Place of eating dinner (P < 0.05) and the person who prepares dinner (P < 0.05) showed significant differences by the SOC group. The relationship of self-efficacy, beliefs regarding nutrition, and eating behaviors to the SOC differed by sports type. Beliefs for football athletes, self-efficacy, and beliefs for baseball athletes were correlated significantly with the SOC, whereas all 3 variables were related to the SOC for handball and other athletes.CONCLUSIONSThis study showed differences in psychosocial factors and eating behaviors between the pre-action and action stages. Nutrition education should include strategies to help young athletes modify their beliefs, mainly misconceptions/disadvantages of nutrition, increase self-efficacy, and adopt specific and desirable eating behaviors. Nutrition education might employ different strategies considering the sports type that student-athletes participate.
