[Relationship between the dietary behavior targets of Health Japan 21 (second term) and perceived food environment and health literacy].

Objective　The interim evaluation of Health Japan 21(second term), a national health promotion plan, suggested that improvements in the food environment did not lead to improvements in individual dietary habits. The present study aimed to evaluate the relationship between the dietary behavior targets of Health Japan 21 (second term) and perceived food environment and health literacy.Method　We conducted an online cross-sectional survey in March 2019 among adults aged 20-64 years. From the 9,667 registered monitors of the research firm, we collected 2,851 responses (29.5% response rate). The perceived food environment (how people perceive the local food environment) was estimated using the following six questions, namely, availability: easy access to nutritionally balanced meals, accessibility: no inconvenience in daily shopping, affordability: access to nutritionally balanced meals at reasonable prices, accommodation: easy access to food services within business hours, acceptability: satisfaction with the quality of food ingredients, and another form of acceptability: adequate food safety. Health literacy was evaluated using five questions related to information gathering, information selection, information transfer, information judgment, and self-determination. Last, we asked the respondents about two dietary behaviors, namely, the frequency of a balanced diet (defined as comprising the staple food, a main dish, and a side dish) and the quantity of vegetable intake, along with sociodemographic information. The analysis included 2,111 respondents, excluding those whose socioeconomic status was unknown. Multiple logistic regression analyses were performed to determine the relationship between perceived food environment and health literacy on dietary behaviors, while adjusting for sociodemographic factors.Result　A balanced diet was associated with the following perceptions of the food environment: "access to nutritionally balanced meals at reasonable prices" (adjusted odds ratio [95% confidence interval] = 1.37 [1.02, 1.82]; women), and "adequate food safety" (1.54 [1.19, 1.98]; men), and health literacy: "information gathering" (0.84 [0.73,0.97]; men) and "self-determination" (1.28 [1.10,1.50], 1.37 [1.14,1.63]; men, women). The quantity of vegetable intake was associated with the following perceptions of the food environment: "easy access to nutritionally balanced meals" (1.54 [1.15,2.06]; men), and "no inconvenience in daily shopping" (1.55 [1.12,2.15]; women), and health literacy: "information transfer" (1.30 [1.10,1.54]; men), and "self-determination" (1.67 [1.38,2.02]; women)).Conclusion　To achieve a balanced diet and increased vegetable intake in a population, it is necessary to promote both the acquisition of a higher level of "self-determination" (rather than "information gathering") in health literacy and the creation of a heathy food environment.

Desirable Diet to Lower the Japanese Nitrogen Footprint: Analysis of the Saitama Prefecture Nutrition Survey 2017.

With the growing interest in healthy and sustainable diets, studying diets with high nutritional quality and low environmental impact is needed. We focused on the nitrogen footprint (NFP)-an indicator of reactive nitrogen loss that causes various environmental impacts-of Japanese diets using individual dietary records and identified the characteristics of lower NFP diets. This cross-sectional study was a secondary data analysis from the 2017 Saitama Prefecture Nutrition Survey. We analyzed the data obtained from a questionnaire and two-day dietary records of 479 men and women aged 30-65 y who had no misreported or missing data. The NFP was calculated using the virtual nitrogen factors of each food group reported in a previous study. After assessing NFP and its contributions, we conducted sub-group analysis for participants with appropriate weight status and adequate protein intake, classifying them into three groups according to tertiles of NFP to protein ratio. We compared NFP, its contributions, and nutrient intake between the groups. The total NFP (kg N/y) was 18.2±5.0 in men and 16.1±4.4 in women. In the sub-group analysis, total NFPs of the lower NFP group were 16.5±3.1 in men and 13.6±2.8 in women. Cereals, pulses, and fish and seafood contributed more significantly to the total NFP in the lower NFP group than in the higher NFP group. These results suggest that adequate protein intake from a variety of food sources is required to lower the environmental impact of adequate diets.

[Changes in dietary behaviors and food-related accessibility issues and information needs during the COVID-19 pandemic: comparison based on household economic status].

Objective　This study aimed to assess the household income changes during COVID-19 pandemic among Japanese adults, and to evaluate how this was related to changes in dietary behaviors and food-related accessibility issues and information needs during the emergency period.Method　We conducted an online cross-sectional survey in July, 2020 among residents (aged 20-69 years) of the 13 prefectures under special confinement during the COVID-19 pandemic. Participants were asked about their dietary behaviors before the pandemic (before February 2020) and during the confinement period (April-May 2020), as well as about their food-related accessibility issues and information needs during the confinement period. Data from 2,225 residents were analyzed. Participants were divided into three groups (decreased, unchanged, and increased) based on the household income changes due to COVID-19. Demographics, dietary behaviors, and food-related accessibility issues and information needs were then compared among these three groups. Multiple logistic regression analyses were performed to examine the effect of household income changes on dietary behavior changes, food-related accessibility issues, and food-related information needs, while adjusting for sociodemographic factors. Furthermore, the effect of household income changes and subjective economic status were also analyzed using multiple logistic regression analyses.Result　The participant distribution in each group were as follows: decreased (34.6%), unchanged (63.9%), and increased (1.6%). Higher proportion of those who were employed part-time, self-employed, or unemployed during the confinement period were found among the decreased group. The odds ratios (OR) of the decreased group were significantly higher than the unchanged group for lower frequency of eating out, and for higher frequency of home-cooking, consuming ready-to-eat convenience meals, and eating with children during the confinement period. Furthermore, regardless of the subjective economic status, the decreased group experienced difficulties in accessing required foods because of shortages and congestion in grocery stores, as well as increased prices. Additionally, food-related information needs regarding reduction of food expenses were also high among the decreased group.Conclusion　Participants with a decreased household income were more likely to experience difficulties with food accessibility and desire information about lowering food-related expenses. Furthermore, they reported lower frequency of eating out, and higher frequency of home-cooking and consuming ready-to-eat convenience meals during the confinement period than before the pandemic. Future studies should evaluate the direction (positive or negative) of these changed food consumption patterns.

Determinants of Changes in the Diet Quality of Japanese Adults during the Coronavirus Disease 2019 Pandemic.

This study evaluated changes in diet quality during the coronavirus disease 2019 (COVID-19) pandemic and its association with variations in attitudes or behavior, as well as health status changes. Participants were Japanese adults aged 20-69 years who resided in 13 prefectures where specific cautions were announced to prevent the spread of the virus. An online survey was conducted in September 2021, and participants were those who shopped for food or prepared meals more than twice a week during the survey. Overall, 2101 participants were analyzed. An improved or worsened diet quality was determined based on changes in food consumption patterns, and participants were categorized into three groups (improved diet quality (IDQ), worsened diet quality (WDQ), and others). The IDQ group participants (10.2%) improved their dietary consciousness during COVID-19, cooked almost everything from ingredients, and increased their balanced meal eating frequency. However, the WDQ participants (11.1%) had worsened dietary consciousness and increased consumption of takeaway meals and alcohol but decreased balanced meal consumption. Cooking frequency changes were not independent determinants of variations in diet quality. Our results show that the diet quality changes during COVID-19 were possibly caused by changes in dietary consciousness or different levels of meal preparation practices.

Effectiveness and Components of Web-Based Interventions on Weight Changes in Adults Who Were Overweight and Obese: A Systematic Review with Meta-Analyses.

Overweight and obesity have reached epidemic proportions worldwide. The COVID-19 pandemic resulted in an increased need for remote implementation of weight-loss interventions; therefore, the effectiveness of web-based interventions needed to be assessed. This study aimed to examine the effectiveness of web-based interventions and their potency in facilitating weight changes in adults who were overweight or obese. We searched PubMed and Ichu-shi Web from the first year of inclusion in each database until the search date (30 September 2020). Among 1466 articles retrieved from the two databases and manual search, 97 were selected to undergo qualitative analysis and 51 articles were subjected to quantitative analysis. Qualitative analysis of 97 articles demonstrated that articles showing significant effectiveness mostly used the following components: social support, self-monitoring for behavior, self-monitoring for the outcome (weight), behavioral goal setting, information about health consequences, and outcome goal setting. Quantitative analysis of 51 articles showed a significant effectiveness of web-based intervention (standardized mean difference, -0.57; 95% confidence interval, -0.75 to -0.40). This study demonstrated the effectiveness of web-based interventions on weight change in adults with overweight and obesity. Subgroup meta-analyses identified personalized information provision and expert advice to be remarkably effective components.

Factors Influencing Changes in Food Preparation during the COVID-19 Pandemic and Associations with Food Intake among Japanese Adults.

The primary aim of this study was to evaluate factors associated with changes in food-preparation practices during the Coronavirus Disease 2019 (COVID-19) pandemic in Japan and its associations to food-group intake. To examine this, a cross-sectional online survey was conducted in July 2020. Participants were 2285 adults aged 20-69 years who resided in any of 13 prefectures in Japan where specific COVID-19 regulations had been implemented. Self-reported changes in food-preparation practices when compared to the pre-COVID-19 pandemic period were measured as "increased" (24.6%), "decreased" (7.3%), and "no change" (68.1%), respectively. Stepwise logistic regression analyses indicated that participants who increased the time and effort for food preparation were younger in age, partially working remotely, experiencing reduced household income due to COVID-19, but highly concerned the importance of diet. On the other hand, participants whose household income decreased, and household economic status worsened, as well as those whose importance of diet deteriorated due to COVID-19 were more likely to decrease time and effort for cooking. Although the increased group were more likely to prepare meals with raw ingredients, the decreased group showed higher frequency of using takeout. These results indicated major determinants of changes in time spending on food preparation in consequence of COVID-19, and highlighted essential targets for future nutrition education.

Effect of workplace dietary intervention on salt intake and sodium-to-potassium ratio of Japanese employees: A quasi-experimental study.

OBJECTIVES: Excess salt intake is a major risk factor for hypertension and cardiovascular disease. Modifying workplace environments has been recognized to be important for reducing salt intake. However, studies examining the effects of improving the workplace environment regarding salt reduction are limited. This study aimed to evaluate the effects of workplace dietary intervention on employees' salt intake and sodium-to-potassium (Na/K) ratio. METHODS: A quasi-experimental study was conducted. Two small business establishments in Saitama Prefecture, Japan, were allocated as the intervention (n = 69) and comparison (n = 68) workplaces, respectively. The 1-year intervention involving healthy lunch and nutrition education was implemented in the intervention workplace. Spot urine samples, physical assessments, and self-administered questionnaire data were collected at baseline, 6 months, and 1 year after the start of the intervention. Analysis of covariance was conducted to investigate differences in the salt intake or Na/K ratio between the study workplaces at year 1. Educational status and rotating work schedules were included as covariates. RESULTS: Salt intake in the intervention workplace decreased significantly from 10.7 to 9.3 g (-1.4 g change; 95% confidence interval [CI]: "-2.4, -0.5"). The adjusted difference in changes in salt intake between workplaces was statistically significant (-3.7 g change; 95% CI: "-5.2, -2.3"). Although no significant change was observed in the Na/K ratio in the intervention workplace (3.37-3.08; -0.29 change; 95% CI: "-0.59, 0.01"), the adjusted difference in changes between the workplaces was statistically significant (-0.60 change; 95% CI: "-1.03, -0.17"). CONCLUSIONS: Providing healthy lunch and nutrition education may be effective approaches to reduce employees' salt intake and Na/K ratio.

[Change in dietary consciousness and its related factors among Japanese adults under the COVID-19 pandemic: Analysis using Dietary Consciousness Scale].

Objectives　This study aims to develop a dietary consciousness scale and examine its reliability and validity, as well as investigate the changes in psychological aspects that influence diet among Japanese adults during the COVID-19 pandemic and clarify its related factors.Methods　An online survey was conducted from July 1, 2020 to July 3, 2020. Participants were adults aged between 20 and 69 years selected from 13 prefectures where the government declared the state of emergency from April to May 2020. All selected participants were shopping or cooking foods for more than 2 days a week at the time of the survey. A total of 2,299 participants were included in the analysis. Dietary consciousness was measured using 12 items, and the construct was examined using factor analysis. Cronbach's alpha was examined as an indicator of internal validity, and the criterion-referenced validity was confirmed using the Kruskal-Wallis test. To determine changes in dietary consciousness, we calculated total scores based on changes in each item of the Dietary Consciousness Scale as follows: no change (0 points), improved (+1 point), and worsening (-1 point). The associations between the changes in dietary consciousness and characteristics or socioeconomic factors of the participants were examined using the chi-squared test and residual analysis.Results　Exploratory and confirmatory factor analyses demonstrated that a model consisting of two factors fitted the data (GFI = 0.958, AGFI = 0.938, CFI = 0.931, RMSEA = 0.066). Cronbach's alpha of the first factor (importance of diet) was 0.838 and 0.734 for the second factor (precedence of diet), and the reliability was confirmed at 0.828 for the entire scale. In the examination of criterion-related validity, the higher the stage of change, the higher the total score of the scale, and a significant difference was observed (P<0.001). The percentage of participants whose precedence worsened was higher than the importance. Significant differences were observed regarding gender, age group, marital status, employment status, household annual income, and income change during the COVID-19 pandemic considering changes in both the importance and precedence of diet. Those who were in the "worsening tendency" group in both the importance and precedence were men, 20-29 years old, unmarried, full-time employees, with a household income of 4-6 million yen during the past year.Conclusion　During the COVID-19 pandemic, the precedence of diet worsened, compared to its importance, and men, young, or unmarried persons show a worsening of dietary consciousness.

[Consumption of ultra-processed foods and relationship between nutrient intake and obesity among participants undergoing specific health checkups provided by National Health Insurance].

Objective　Obesity associated with an increased consumption of ultra-processed foods (UPF) has been reported by studies abroad using the NOVA food classification system, an international framework for classifying food according to the degree of processing. However, no such study has been conducted in Japan. In this study, we evaluated the association between UPF consumption, nutrient intake, and obesity using the NOVA system.Method　In September 2017, we conducted a survey using a questionnaire of patients who had attended routine health checkups in Manazuru Town, Kanagawa Prefecture and collected their three-day dietary records as well as medical examination results. The final analysis included 169 patients (66 men, 103 women). Food consumed by the respondents were classified into four groups of NOVA systems. The dietary share of UPF (UPF energy ratio) was compared to total energy intake (except alcoholic beverages and eating out). Nutrient intake and obesity risk were compared across the UPF energy ratio tertile (low, middle, and high intake). Covariance and logistic regression analysis were conducted and adjusted based on age, sex, household structure, education, income, and total energy intake (except energy-providing nutrients, macronutrients, and protein intake per body weight) to analyze the association between UPF consumption and nutrient intake. Finally, for obesity, we adjusted for physical activity and smoking status using a similar analysis of the relationship between UPF consumption and energy providing nutrients and macronutrients.Result　Approximately 75% of patients investigated were older than 65 years. The average (standard deviation) UPF energy ratio was 29.7% (15.0). There were no significant differences in socioeconomic status among groups according to the UPF energy ratio. The high-UPF group had a significantly greater total energy intake. However, the protein energy ratio, protein intake per body weight, dietary fiber, and vitamins A, E, K, B1, B6, C, niacin, folic acid, potassium, magnesium, and iron intake were significantly lower in the high-UPF group. Moreover, the high-UPF group had a significantly higher BMI. The odds ratio for obesity was higher (4.51[1.50-13.57]) in the high-UPF group than in the low-UPF group (1.00).Conclusion　Those who consumed more UPF had lower protein intake and suffered from multiple vitamin and mineral deficiencies. Furthermore, their energy intake was greater, and the odds ratio for obesity was significantly higher. It has been suggested that excessive UPF consumption warrants further attention.

Phylogeny, Prevalence, and Shiga Toxin (Stx) Production of Clinical Escherichia coli O157 Clade 2 Strains Isolated in Shimane Prefecture, Japan.

This study investigated the genetic and pathogenic variation of the subgroups of clade 2 strains of Shiga toxin (Stx)-producing Escherichia coli (STEC) O157. A total of 111 strains of STEC O157 isolated in Shimane prefecture, Japan, were classified in clade 2 (n = 39), clade 3 (n = 16), clade 4/5 (n = 3), clade 7 (n = 14), clade 8 (n = 17), and clade 12 (n = 22) by single-nucleotide polymorphism analysis and lineage-specific polymorphism assay-6. These results showed a distinct difference from our previous study in which clade 3 strains were the most prevalent strains in three other prefectures in Japan, indicating that the clade distribution of O157 strains was different in different geographic areas in Japan. Phylogenetic analysis using insertion sequence (IS) 629 distribution data showed that clade 2 strains formed two clusters, designated 2a and 2b. Stx2 production by cluster 2b strains was significantly higher than by cluster 2a strains (P < 0.01). In addition, population genetic analysis of the clade 2 strains showed significant linkage disequilibrium in the IS629 distribution of the strains in clusters 2a and 2b (P < 0.05). The ΦPT values calculated using the IS629 distribution data indicated that strains in clusters 2a and 2b were genetically different (P < 0.001). Cluster 2b strains are a highly pathogenic phylogenetic group and their geographic spread may be a serious public health concern.

Consumption of ultra-processed foods decreases the quality of the overall diet of middle-aged Japanese adults.

OBJECTIVE: To estimate the consumption of ultra-processed foods and determine its association with dietary quality among middle-aged Japanese adults. DESIGN: Cross-sectional study using data from the Saitama Prefecture Health and Nutrition Survey 2011. Dietary intake was assessed using one- or two-day dietary records. Sociodemographic and lifestyle factors were obtained via self-administered questionnaire. Food items were classified according to the NOVA system into four groups: unprocessed or minimally processed foods; processed culinary ingredients; processed foods; and ultra-processed foods. The dietary share of each NOVA food group and their subgroups was calculated in relation to total energy intake, and the average dietary content of key nutrients was determined across tertiles of the dietary energy share of ultra-processed foods (low, middle and high intake). SETTING: Saitama Prefecture in Japan. PARTICIPANTS: Community-dwelling adults aged 30-59 years (256 men, 361 women). RESULTS: Consumption of unprocessed or minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods contributed 44·9 (se 0·8) %, 5·5 (se 0·2) %, 11·3 (se 0·4) % and 38·2 (se 0·9) % of total daily energy intake, respectively. A positive and statistically significant linear trend was found between the dietary share of ultra-processed foods (tertiles) and the dietary content of total and saturated fat, while an inverse relationship was observed for protein, vitamin K, vitamin B6, dietary fibre, magnesium, phosphorus and iron. CONCLUSIONS: Our findings show that higher consumption of ultra-processed foods was associated with decreased dietary quality among Japanese adults.

Rapid and Accurate Diagnosis Based on Real-Time PCR Cycle Threshold Value for the Identification of Campylobacter jejuni, astA Gene-Positive Escherichia coli, and eae Gene-Positive E. coli.

We previously developed a multiplex real-time PCR assay (Rapid Foodborne Bacterial Screening 24 ver.5, [RFBS24 ver.5]) for simultaneous detection of 24 foodborne bacterial targets. Here, to overcome the discrepancy of the results from RFBS24 ver.5 and bacterial culture methods (BC), we analyzed 246 human clinical samples from 49 gastroenteritis outbreaks using RFBS24 ver.5 and evaluated the correlation between the cycle threshold (CT) value of RFBS24 ver.5 and the BC results. The results showed that the RFBS24 ver.5 was more sensitive than BC for Campylobacter jejuni and Escherichia coli harboring astA or eae, with positive predictive values (PPV) of 45.5-87.0% and a kappa coefficient (KC) of 0.60-0.92, respectively. The CTs were significantly different between BC-positive and -negative samples (p ＜ 0.01). All RFBS24 ver.5-positive samples were BC-positive under the lower confidence interval (CI) limit of 95% or 99% for the CT of the BC-negative samples. We set the 95% or 99% CI lower limit to the determination CT (d-CT) to discriminate for assured BC-positive results (d-CTs: 27.42-30.86), and subsequently the PPVs (94.7%-100.0%) and KCs (0.89-0.95) of the 3 targets were increased. Together, we concluded that the implication of a d-CT-based approach would be a valuable tool for rapid and accurate diagnoses using the RFBS24 ver.5 system.

Dietary intake and weight status of urban Thai preadolescents in the context of food environment.

Little attention has been devoted to the importance of understanding the association between dietary intake and childhood obesity in Thailand. This study aimed to explore food types affecting the weight status of preadolescents in urban settings, where obesity is remarkably prevalent. This study was conducted in 2015-2016 and assessed the dietary intake of 263 children aged 10-12 years from Bangkok Metropolitan Regions through three- nonconsecutive-day 24 h recall. Lifestyle and sociodemographic information was obtained using questionnaires. Participants were classified into non-obese and overweight/obese groups based on the WHO child growth standard curve. Foods were categorized into 13 groups based on Thailand's dietary guidelines and food environment context regarding two eating occasions (main and between meals) of children, which resulted in the newly classified "street-side snacks". Data were examined using analysis of covariance and multiple linear regression analysis. After adjusting for sex and energy misreporting, overweight/obese participants had higher energy and macronutrient intake and consumed more cereal grains, meat/fish, flavored milk, and sugar-sweetened beverages during main meals and street-side snacks and confectioneries during between meals than non-obese participants. The consumption of street-side snacks had the highest beta coefficient on BMI z-scores among the food types in the model, adjusted further for energy intakes. Street-side snacks may be an important predictor of obesity in Thai children. A prospective investigation of the impact of accessibility and availability of this food item is needed.

Use of focus group interviews with public health nurses to identify the efforts of and challenges faced by branches of the Japan Health Insurance Association to achieve good performance of the Specific Health Guidance initiatives.

Objectives Aiming at improvement of the Japan Health Insurance Association's Specific Health Guidance initiatives and human resource development, we conducted a qualitative study to clarify the features necessary for and the challenges hindering the achievement of good performance of the initiatives.Methods From November 2014 to January 2015, we conducted 10 focus group interviews, each 90 minutes long, with 64 public health nurses from 10 Japan Health Insurance Association branches. In addition, self-administered questionnaires were administered to obtain the participants' basic characteristics. After we excluded one group for failing to meet our performance targets, we divided the remaining nine focus groups according to two patterns: Maintenance and Progress. The four focus groups fitting the Maintenance pattern had a well-established track record, and the five focus groups fitting the Progress pattern had a track record of good growth. Using open coding of the interview transcripts, we extracted efforts or needs in two domains, individual and branch, Then, we placed codes in eight main categories: [quality], [general practice], [dietary guidance practice], [success factor], [branch system], [training and skill development], [approach to the member office], and [past efforts]. We further extracted important subcategories based on their rates of appearance within branches.Results Data from 56 female public health nurses working at nine branches were included in the analysis. With respect to the individual domain, subcategories such as "building rapport," "creating the physical environment," and "taking the initiative in evaluating one's own lifestyle" in the 〈high emphasis〉 segment of the [general practice] category were common to both patterns. In addition, "increasing opportunities for training" and "enhancement of training program content" were found for both patterns in relation to the 〈demand〉 segment of the [training and skill development] category. However, most participants chose "yes" in response to whether there was ample training opportunity.Conclusion This study showed some common efforts and practices among public health nurses in both patterns, which indicates good performance of the Specific Health Guidance initiatives. However, there is a need to further enhance the training program to strengthen the entire organization. Future studies should focus on understanding the characteristics of and factors involved in low-performing branches.

Effectiveness of a Nutrition Education Program to Improve Children's Chewing Habits.

This quasi-experimental study determined whether the nutrition education program we developed to promote chewing food properly influenced children's chewing habits successfully. Four kindergarten classes in Japan (150 children, aged 5-6 years) were studied; one class received the educational program in the classroom and at home (Group A) and three classes received the program in the classroom only (Group B). The educational program was integrated into the classes' daily curriculum for five weeks. It included storytelling with large picture books, chewing consciously while eating lunch, singing a song with gestures, and greetings before and after meals (both groups). Group A also used a paper textbook and was provided information by the leaflet to encourage guardians to implement the program at home. Chewing habits before and after intervention were evaluated: (1) guardians completed seven questionnaire items related to chewing habits and chewing movement and (2) the number of chews and time spent eating the test meal were measured by a portable chewing sensor. Both approaches improved the children's chewing habits; however, no difference was found between the two groups. We concluded that this intervention could be used to improve chewing habits in young children even without active involvement of their guardians.

Nutritional status and dietary intake among pregnant women in relation to pre-pregnancy body mass index in Japan.

Objective The present study examined nutritional status and dietary intake of pregnant women in Japan in relation to pre-pregnancy body mass index (BMI).Methods Participants included 141 Japanese women with singleton pregnancies, from the outpatient department of the S hospital, Gunma prefecture, Japan. Two-day food records, dietary assessment questionnaires, and clinical records were obtained at 20 weeks gestation. Nine patients were excluded from the study due to morning sickness. The remaining 132 participants were divided into 3 groups according to pre-pregnancy BMI: underweight, normal weight, and overweight. Nutritional status and dietary intake were analyzed in relation to BMI using the chi-square test, Fisher's exact test, Kruskal-Wallis test, one-way analysis of variance, and analysis of covariance with adjustment for age, employment status, and total energy intake.Results Women who were underweight before pregnancy were more frequently working full-time than normal weight and overweight women. Underweight women were also more frequently anemic (P=0.038, underweight 39.3%, normal weight 24.7%, overweight 0%) and had lower mean hemoglobin (Hb) (P=0.021, underweight 11.3 g/dL, normal weight 11.6 g/dL, overweight 12.1 g/dL) and hematocrit (Hct) levels (P=0.025, underweight 33.7%, normal weight 34.3%, overweight 36.0%). Their dietary intake of protein, iron, magnesium, and folic acid was lower than that of normal weight and overweight women. Their meals tended to include fewer meat, fish, egg, and soybean dishes (underweight, mean of 4.7 servings per day; normal weight, 6.1 servings; overweight, 6.1 servings).Conclusion Pregnant women who were underweight before pregnancy had increased risk of anemia as well as reduced Hb and Hct levels. They had lower dietary intake of protein, iron and folic acid compared to women in the other BMI categories. Anemia and these nutrient deficiencies are known risk factors for low birth weight. Our findings suggest the importance of providing underweight pregnant women with support to improve dietary intake during their pregnancy, especially to increase intake of protein and iron through consumption of fish and meat dishes.

Why Is Creating a Healthy Food Environment So Crucial to Making Improvements in Diet-Related NCDs?

Non-communicable diseases (NCDs) such as cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes are the leading cause of death worldwide. To decrease the global burden of NCDs and strengthen national efforts to combat NCDs, the World Health Organization (WHO) released the Global Action Plan for the Prevention and Control of NCDs 2013-2020. This plan provides established procedures and several policy options for member countries and other partners. Although many countries recognize that prevention of NCDs is an important health priority, their governments currently face a challenge: How do they adopt a multi-sectoral approach to promoting a healthy lifestyle among their populations? For this, all sectors of the food system (primary production, food processing, distribution, marketing, retail, catering, and food service) need to coordinate with each other for future governance. Since regulatory policy intervention areas for diet-related NCDs are widespread throughout the global food system, for future perspectives, comprehensive and coordinated approaches are needed for policy development and implementation across all levels of governments and food sectors in order to ensure sustainable policy action.

Association of enjoyable childhood mealtimes with adult eating behaviors and subjective diet-related quality of life.

OBJECTIVE: This study examined whether the experience of enjoyable mealtimes at home during childhood was related to eating behaviors and subjective diet-related quality of life in adulthood. METHODS: The study used data (n = 2,936) obtained from a research program about Shokuiku (food and nutrition education) conducted by the Cabinet Office in Japan in November and December 2009. The study employed logistic regression adjusted for all predictor variables. RESULTS: Enjoyable eating experiences in childhood were positively associated with a balanced diet (meals with 3 dishes; odds ratio [OR]: 1.78, 95% confidence interval [CI]: 1.45-2.19), eating vegetable dishes (OR: 1.71, 95% CI: 1.37-2.12), and subjective diet-related quality of life scores (OR: 3.84, 95% CI: 3.14-4.70) in adulthood. CONCLUSIONS AND IMPLICATIONS: This study suggests that enjoyable eating experiences at home during childhood appear to promote healthy eating habits and the development of a positive diet-related quality of life in the future.

[Factors and prosesses associated with weight loss in male workers in a specific health guidance program. A qualitative analysis of in-depth interviews].

OBJECTIVES: A qualitative analysis was conducted to identify factors important for weight loss through a specific health guidance program and to understand the processes that were crucial in achieving success. METHODS: Twenty-six male workers aged 41-59 years from five corporate health insurance societies in four prefectures who had lost > or = 4% weight by attending the six-month specific health guidance program were invited to participate in the in-depth interviews. Data were collected between October and December 2009. We audio taped the 30-minute interviews and performed qualitative analysis on the transcripts using a grounded theory. The discussion by the expert panel strengthened the validity of the analysis. RESULTS: The mean age was 49.9 +/- 5.6 years, and the average weight loss was 6.8 +/- 2.5%. All subjects were somewhat concerned about their health status and body shape before the first appointment, but two major prosesses, "critical feeling" and "sense of obligation," were identified after the first appointment. We also identified innovative efforts in all subjects during the process. Those who reported a "sense of obligation" at the beginning and those who had a negative perception during the program were found to have higher risks of weight rebound after the program was over. We considered personality, values, attitudes toward the program, and support from both family and workplace as the intervening conditions for behavior modification. CONCLUSION: Since everyone aged 40-74 years with a certain risk of metabolic syndromes is obligated by law to participate in the specific health guidance program, weight loss is challenging for those who are not motivated enough to change their behaviors. Therefore, the initial assessment of one's motivations, followed by interventions taken in consideration of one's lifestyle and social background, are crucial for the success of a weight loss program, as is the use of a client-centered approach.
