BACKGROUND/OBJECTIVES: While many obesity studies have pointed out the importance of meal regularity, few have conducted empirical analyses using data from food diaries. We examined the association between meal regularity (i.e., meal time regularity [MTR] and calorie intake regularity [CIR]) and weight loss. SUBJECTS/METHODS: We collected food diary data from 637 women who had participated in commercial weight loss programs for 28-168 days (4-24 weeks). This study defined "meal regularity" in terms of two concepts: MTR and CIR. MTR refers to how regularly people eat their meals (i.e., at certain times each day), whereas CIR refers to how regularly people consume a certain amount of calories at each meal. We conducted multiple regression analyses. RESULTS: MTR (model 1: β = -2,576.526, P < 0.001; model 2: β = -1511.447, P < 0.05; model 3: β = -1,721.428, P < 0.05) and CIR (model 1: β = -1,231.551, P < 0.01; model 2: β = -2,082.353, P < 0.001; model 3: β = -1,343.490, P < 0.01) turned out to be significant determinants of the amount of weight loss in breakfast, lunch, and dinner contexts. While meal regularity (i.e., MTR and CIR) was significantly associated with weight loss, daily calorie intake from meals was not significantly associated with the amount of weight loss (model 1: β = 0.13, P > 0.05; model 2: β = 0.11, P > 0.05; model 3: β = 0.14, P > 0.05). Subjects who consumed an equal amount of calories per meal throughout the day lost more weight than those who did not (model 4: β = -3,675.51, P < 0.001). CONCLUSIONS: Eating each meal (i.e., breakfast, lunch, and dinner) at a certain time every day may increase weight loss success. Also, consuming the same amount of calories at each meal may help weight loss success.

Consuming regular meals has been studied in relation to better health, while higher regularity of eating-out has been linked to obesity. This study examined whether acculturation was associated with regularity of meals, eating-out, and overweight in Korean Americans. Pre-tested questionnaires were mailed to a U.S. national sample with Korean American surnames, and 55% of the deliverable sample responded, producing 356 usable questionnaires. Acculturation was measured using a two-culture matrix model and Gordon's theoretical work, and showed there were three distinct groups (acculturated, bicultural, and traditional). Only 36% reported that they regularly ate three meals a day. Breakfast was the least frequent meal of the day with 43% reporting eating breakfast everyday. More than half (58%) reported that they usually eat out or get take-out food at least once a week. After controlling for age, sex, income, education, and working status, higher acculturation was related to greater regularity of eating-out, but not meal regularity. A total of 28% of men and 6% of women were overweight (BMI>25), and there were significant and positive relationships between body weight status and acculturation in men but not women. However, no significant relationships between frequency of meals and eating-out and overweight status were present. This study did not find significant relationships of meal regularity and eating-out with body weight, however, given the positive relationship between acculturation and eating-out among the subjects and the well-established relationship between eating-out and obesity, nutrition education about skipping meals and eating-for Korean Americans may be useful to prevent such relationships from developing.

The purpose of this study was to assess dietary variety by food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers and night snacks per week, and duration of meal) in 138 female university students residing in Bucheon and its adjacent area. Food habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average DDS, MBS, and DVS were $3.87{\pm}0.57$, $7.27{\pm}1.48$, and $12.59{\pm}3.14$, respectively. The DDS($2.21{\pm}0.83$) of the breakfast in the group in which the regularity of meal time per week was 5~7 days was significantly higher($p$ <0.01) than the DDS($1.47{\pm}0.96$) of the breakfast in the group in which the regularity of meal time per week was ${\leq}$2 days. The MBS($6.69{\pm}1.43$) of the group in which the regularity of meal times per week was ${\leq}2$ days was significantly lower($p$ <0.01) than the MBS of the group in which the regularity of meal time per week was ${\geq}3$ days. The DDS($2.38{\pm}0.69$) of the breakfast in the breakfast over eating group was significantly higher($p$ <0.001) than the DDS($1.83{\pm}0.83$) of breakfast under eating group. The MBS($6.56{\pm}1.46$) in the breakfast skipping group was significantly lower($p$ <0.01) than the MBS(about 7.6) in other breakfast eating groups, and the DVS ($13.79{\pm}3.21$) in the breakfast over eating group was significantly higher($p$ <0.05) than the DVS($11.53{\pm}2.94$) in the breakfast skipping group. The DDS of breakfast, lunch, and snack were not significantly correlated with the number of suppers per week, but the DDS($2.65{\pm}0.52$) of the supper in the group in which the number of suppers per week was 7 was significantly higher($p$ <0.05) than the DDS($2.22{\pm}0.49$, $2.25{\pm}0.62$) of the supper in the group in which the number of suppers per week was ${\leq}2$, 3~4. The DDS, MBS and DVS were not significantly correlated with the number of suppers per week. The DDS($1.33{\pm}1.25$) of the breakfast in the group in which the number of night snacks per week was 6~7 was significantly lower($p$ <0.05) than the DDS of the breakfast in the group in which the number of night snacks was ${\leq}5$. Also, the DDS($4.42{\pm}0.32$) per day in the group in which the duration of meal was <10 min. was significantly higher($p$ <0.01) than the DDS($3.51{\pm}0.53$) per day in the group in which the duration of meal was ${\geq}30$ min. These findings suggest that nutritional education based on female university students' eating variety and food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers, and night snacks per week, and duration of meal) may be required to improve dietary variety.

This study was performed to assess the effect of eating behaviors and health-related variables on overall dietary quality. Ninety-four(male 21, female 73) elderly who were over 60 residing in middle income areas in Cheongju city participated. Information on general characteristics of the elderly, health-related life style, regularity of meal, meal balance and desirable eating habits were obtained by interview based on questionnare. Dietary nutrient intake data were obtained through the 24 hour recall method. The mean age and BMI of the subjects were 73.3 years old and 23.3(male 21.8 female 23.7) respectively. The proportions of underweight and hypertension were 19.2% and 36.2%. Most nutrients except vitamin $B_2$ and calcium were consumed over 75% of the RDA. The Mean Adequacy of Ratio(MAR) of nutrient intake was 0.64(male 0.72, female 0.62). The average score of regularity of meal, meal balance, and desirable eating habits was 14.4 out of a possible 16, 13.7 out of a possible 24 and 5.5 out of a possible 16 points respectively. Male than female, older subjects than young subjects, and those living with their spouses than with other family or living alone had better scores in eating behaviors. Smoking, chewing ability and eating alone vs eating with company affected overall of regulality of meal and meal balance(p<0.05). Positive correlation (p<0.05) was also dietary quality. There was a positive correlation between the mean adequacy ratio, score observed between scores in regularity of meal and meal balance. Therefore, the elderly should be encouraged to eat a variety of food, maintain good dental health, keep regularity of meal and have meals with company to help improve overall dietary quality and eventually achieve optimal nutritional status.

This study aimed to investigate the relationship between meal regularity (i.e. breakfast intake and meal-times), and the risk of metabolic syndrome (MetS) among generally healthy Korean single-person household adults (≤60 years, n=594) based on the Seventh Korean National Health Examination and Nutrition Survey (KNHANES) (2016~2018). Among men (n=325), the breakfast intake frequency was not significantly associated with the pervalence of MetS. However, men consuming a regular meal at least once a day showed a lower prevalence of MetS compared to those whose meals were irregular. These patterns remained after adjusting for age, smoking and drinking habits, individual income, education level, exercise, and total calorie intake. An association between meal regularity and MetS risk was observed in post-menopausal women (n=84), but not in pre-menopausal women (n=185). More specifically post-menopausal women with irregular breakfast eating habits or eating no breakfast at all showed a significantly higher risk of MetS than those eating breakfast regularly after the adjustment. The analysis revealed an odds ratio (OR) of 8.46, confidence intervals (CIs): 1.149~62.199, P<0.05 in irregular breakfast eaters, and an OR of 13.377, CIs: 1.665~107.511, P<0.05, in those who ate no breakfast. Furthermore, post-menopausal women who had irregular meals daily showed a higher risk of MetS than those consuming one or more regular meals/day after the adjustment (OR: 16.888, CIs: 1.258~226.655, P<0.05). In conclusion, the results from this study may be used for formulating optimal dietary guidelines for the prevention and the management of MetS in adults in single-person households.

Dietary habits are known to be closely related not only to chronic diseases such as cardiovascular disease and diabetes, but also to self-rated health (SRH). Consequently, there is a highly important lifestyle component in maintaining a healthy life. The aim of the present study was to determine the correlation between diverse dietary habits based on the Sasang constitutions (SC) and SRH. The data were collected from 2,984 participants who met the constitution pharmacology criteria and whose SC were clinically confirmed by SC professionals. Dietary habits were observed by assessing the regularity of diet, meal volume, and meal speed; single-answer questions were used for SRH. Fisher's exact/chi-square test and logistic regression were used to analyze the correlation between dietary habits depending on constitutional type and SRH. In association with constitutional SRH, the Taeum type is related to the amount of meal, the Soeum and Soyang types are related to the regularity of meal and meal volume. In the Taeum type, there was a significantly higher risk of lower SRH when meal volumes were irregular less than previous amounts. Irregular diet, as well as increased or decreased meal volume, negatively correlated with SRH in the Soeum type; in the Soyang type, irregular diet and decreased or irregular meal volume negatively affected SRH. This showed the presence of the different effects of dietary habits on health depending on constitution and also confirmed the association of the regularity of diet and meal volume based on constitution and the frequency of bad dietary habits with SRH. We suggest that personalized healthcare with adequate dietary improvement considering constitution is needed for health management or improvement.

This study was conducted to find and compare the effects of dietary habits on and obesity indices and nutrition intakes among four hundreds and seven healthy adults males subjects. Subjects were classified as regular meal group(RMG) and irregular meal group(IRMG). Two hundreds and thirteen subjects of RMG had regularly 3times meal(time and amount) per 1 day during more than last 6 month. One hudred and ninety four subjects of IRMG(n=194) were not had regularly meal during last 6 month. Obesity indices were BMI(Body Mass Index), WHR(Waist Hip Ratio) and PIBW(Percentage of Ideal Body Weight). And the mean BMI, WHR and PIBW of RMG and IRMG were 23.1, 0.91, 104.8 and 24.7, 0.93, 112.9. PIBW of IMG were significantly lower than IRMG(p<0.01). The mean daily intakes of starches, seeds, meats, eggs, fishes, milk, fats and processed food intakes of RMG were significantly lower than IRMG. And the mean daily intakes of vegetables, mushrooms and beverages intakes of the IRMG were significantly lower than RMG. Energy intake of RMG and IRMG were 1978.2kcal and 1988.2kcal. For nutrient intake, vitamin C intake of IRMG was significantly lower than RMG. But niacin and cholesterol intake of RMG were significantly lower than the IRMG. Meal regularity was mainly related with obesity indices and nutrition intakes. Therefore, it might be necessary to manage meal regularity to prevent obesity and chronic disease in Korean adult males.

Background: This study aimed at investigating the meal regularity, health, and oral health habits of single Korean households to understand the impact of these factors on the risk of metabolic syndrome, in addition to preventing and managing metabolic syndrome. Methods: Using raw data from the 8th Korea National Health and Nutrition Examination Survey (2019), 274 study subjects, aged 19 to 64, were selected primarily from single adult households. Complex sample statistical analysis was performed using the Predictive Analytics Software Statistics ver. 18.0 program. Results: Regarding the meal regularity in single-person households in Korea, the younger group outperformed the middle-aged group, and those who drank more than once a month performed better than those who drank less than once a month. In terms of oral health, regardless of the age and the income level, participants who ate three meals a day had a higher rate of speech problems and chewing difficulties than those who ate irregularly or regularly on a regular day. Factors influencing the risk of developing metabolic syndrome were age, speech problems, and frequency of toothbrushing. Compared to the younger group, there were 0.361 times more people in the middle-aged group; and compared to those without speech problems, there were 1.161 more people with speech problem. Compared to those who tooth brushed more than four times a day, there were 1.284 more people who tooth brushed 2 to 3 times a day and there were 5.673 times more people who tooth brushed less than once. Conclusion: Based on the study results, it is necessary to implement a program that can plan and apply customized management measures and prevent metabolic syndrome by improving and correcting the health and oral health behaviors of single-person households in Korea. Therefore, active mediation measures, such as support and publicity at the local or national level, should be planned.

서울 시내와 경기도 파주시에 소재하는 남녀 공학 고등학교의 식생활 실태 중 식사 규칙성과 식사횟수와 관련된 사항에 대하여 조사하였다. 남녀 고등학생의 식사의 규칙성에서는 남학생에 비해 여학생의 경우 상대적으로 하루 식사가 비교적 규칙적인 것으로 나타났다. 1일 동안의 식사횟수는 남녀학생 모두 대체로 '1일 3식'을 하는 것으로 나타났다. 식사섭취횟수의 형성 시기에 대한 결과에서는 남녀학생은 모두 '중학교'로 나타났으며, 특히 여학생에 있어서는 '학령기 이전'이라고 답한 경우도 28.7%로 높게 나타났다. 활동에 가장 영향을 주는 식사에 대한 답변은 남학생은 점심(41.0%)이라고 답한 결과가 가장 높은 반면 여학생은 '아침'(39.8%)이라는 결과가 높게 나타났다. 학년별 식사섭취 빈도와 규칙성의 항목에 대한 분석 결과에서는 전반적으로 규칙적인 식사를 하고 있는 것으로 나타났지만 유의차가 없었다(p<0.05). 1일 식사횟수에서는 1~3학년 모두 대체적으로 '1일 3식'을 하는 것으로 나타났다. 학년별 식사섭취횟수 형성시기에서는 모든 학년에서 '중학교'와 '학령기 전'의 순의 결과를 보여 주었다. 식사의 규칙성과 일반사항의 분석 결과, 가족 수 '5명'과 '용돈이 적을수록'의 항목에서 규칙적인 식사가 이루어지고 있었다. 용돈 중 '3만원 이하'의 경우 '5만원 이상'의 식비 지출의 경우 비교적 규칙적인 것으로 나타났다. 식사를 준비하는 사람에 따라서는 '어머니'가 식사를 준비하는 경우 상대적으로 하루 식사가 비교적 규칙적인 것으로 나타났다. 부모의 연령과 교육정도가 높고 월 가구 소득이 많을수록 하루 식사가 비교적 규칙적으로 나타났다. 부모의 직업에 따라서는 아버지 '사무직'(149명(56.9%))과 어머니 '전업주부'(279명(56.9%))인 경우 하루 식사가 비교적 규칙적인 것으로 나타났다. 1일 동안의 식사횟수와 일반사항과의 차이분석 결과에서는 대체적으로 '1일 3식'을 하는 것으로 볼 수 있었다. 한 달 용돈 '5만원 이하'의 경우 54.3%가 '1일 3식'을 하는 것으로 나타났고 식사를 준비하는 사람의 경우, '스스로' 이외에는 대체적으로 1일 3식을 하는 것으로 나타났다. 부모의 연령, 부모 학력, 월 가족소득에 따라 식사횟수와 차이를 보여주었다. 식사 섭취횟수의 형성 시기와 일반사항을 분석한 결과, '용돈'과 ' 식사를 준비하는 사람'의 결과는 '중학교'>'학령기전' 순으로 나타났다. 수면 시간과의 분석결과에서는 '5~8시간'이라고 응답한 학생들의 경우 '중학교 때 형성되었다'에서 높은 결과를 보였다. 또한 부모 연령이 낮을수록 '중학교 때 형성되었다'는 결과가 높았고 연령이 높아질수록 '학령기 전'의 결과가 높게 나타났다. 월가구소득과 식사섭취횟수와의 분석 결과에서는 소득이 높을수록 '학령기 전'이라고 답변한 결과가 높았고 소득이 낮을수록 '중학교 때 형성되었다'에서 높은 결과를 보여 주었다. 전체적으로 볼 때, '중학교 때 형성되었다'가 34.6%으로 가장 높게 나타났고, '학령 전'(23.8%), '초등학교 4~6학년 전'(13.7%), '초등학교 2학년 전'(11.8%) 순으로 나타났다. 한 끼 식사 중 자신활동에 가장 큰 영향을 미치는 식사를 분석한 결과에서는 '점심'이 37.6%으로 가장 높게 나타났고, '아침'(35.8%), '저녁'(22.8%) 순으로 나타나 전반적 '점심'이 자신의 활동에 가장 큰 영향을 미친다고 생각하는 것을 볼 수 있었다. 한 달 용돈 '9만원 이하'의 경우 '점심'이, '10~20만원'의 경우 '아침'이, '21만원 이상'의 경우 '저녁'이 가장 큰 영향을 미친다고 하여 차이를 보였다. 수면시간과의 분석 결과에서는 4, 5, 6시간의 경우 '아침'이, '7시간 이상' 수면을 하는 경우 '점심'이 가장 큰 영향을 미친다는 결과였다. 아버지의 연령은 낮을수록 어머니의 연령은 높을수록 '아침'의 영향력이 크다는 상반된 결과가 나타났다. 또한 월가구소득이 증가할수록 '아침'의 영향력을 높게 느끼고 있는 결과였다. 이상의 결과를 종합해 보면, 고등학생의 식생활태도는 성별과 학년별로 차이를 나타내어 차별화된 영양교육과 식생활 태도에 관련한 기초지식을 강화해야 함을 알 수 있었다. 식사의 규칙성과 식사횟수에 있어서는 부모의 특성과 월 가족 소득에서 차이가 나타나 고등학생 개인의 영양교육은 물론이고 가정을 연계한 영양지도에 대한 대책이 필요한 것을 확인할 수 있었다. 식사횟수의 형성은 이미 고등학생 이전에 만들어져 고정되어 있는 결과가 나타나기에 특히 다양한 교육방법을 활용하여 그 중요성을 인지하도록 만들고 올바른 식습관으로 개선된 후 유지되도록 지속적인 모니터링이 요구되었다. 아침식사보다 점심식사에 대한 영향력이 나타난 결과를 보면, 아침식사에 대한 결식과 영양불균형을 예측해 볼 수 있었고 영양 섭취가 세 끼니에 골고루 분배될 수 있는 영양지도의 중요성과 아침식사와 결식에 고등학생의 식생활태도의 후속연구를 진행해야 할 필요성을 확신할 수 있었다. 본 조사의 결과는 남녀 고등학생이 식생활태도와 영향을 미치는 요인들과 관련하여 분석해서, 실천적인 식습관 형성 및 개선에 대한 개별적이면서 세부적인 영양교육 프로그램을 구축하는데 있어 기초 자료가 활용되어지길 바란다. 또한 지속적이면서 다각적인 식사관련 후속 연구들이 진행되어 영양교육 시간이 정규 수업시간으로 정착하는 데 있어 도움이 되리라 생각된다.
