Children’s eating habits are established early in life and parents play a major role therein. Pregnancy is a teachable moment for the promotion of healthy eating because many women are concerned about their babies’ health and have frequent contact with healthcare providers. We investigated the association between diet quality during pregnancy and the offspring. A total of 691 sets of data on pregnant mothers and their 3-year-old offspring were obtained from the Seiiku Boshi cohort study. The total offspring diet quality score showed a linear trend with the maternal diet quality score. A high diet quality score during pregnancy was positively associated with that of offspring, suggesting the importance of nutritional education in pregnant women to improve their diet quality.

<b>Objective</b>: To evaluate free-living gait characteristics in comparison with in-laboratory walking among Japanese university students.
<br><b>Methods</b>: Gait characteristics (walking speed, step length, and cadence) were measured in a laboratory setting and a free-living situation. In both settings, the gait characteristics were assessed using motion sensors attached to both ankles. In the laboratory setting, subjects walked on a circular course for 5 minutes while maintaining their natural walking speed, which was assessed in 5-m walking tests. In a free-living situation, subjects were asked to wear the devices for 1 week. Frequencies of values higher than, the same as, and lower than the data measured in the laboratory were calculated for the free-living data. The effect of footwear type was also examined in a free-living situation.
<br><b>Results</b>: Eight healthy university students (age: 22.1 ± 0.4 years, six female subjects) completed the study. During the free-living period, the frequencies of slower walking speed, shorter step length, and slower cadence compared with the in-laboratory period were 79.4 ± 14.6%, 69.8 ± 25.3%, and 73.4 ± 15.6%, respectively. Walking speed, step length, and cadence were significantly lower when subjects wore slippers compared with other footwears.
<br><b>Conclusion</b>: Healthy Japanese university students’ walking speed, step length, and cadence during free-living were lower compared with the in-laboratory setting. This suggests that the evaluation of walking in an in-laboratory setting may not reflect free-living walking among university students.DOI： 10.24804/ree.2309

<p>This study aimed to determine whether participation in meal preparation or increased the opportunities to participate in meal preparation during the pandemic were related to dietary balance, including chronological relationships. An online cross-sectional survey was conducted in February 2021 among individuals registered with a company that provides meals to children aged 2−6 years. The survey gathered data on children’s eating behavior and lifestyle, and the current situation and changes following the COVID-19 outbreak. The 1878 participants were categorized into two groups: those with and without opportunities to be involved in meal preparation for the post-COVID-19 current analysis (n＝1056 and 822, respectively) and those with an increase (n＝478) and those with no change (n＝1400) for the analysis of change compared to the pre-COVID-19 analysis. Multiple regression analyses were performed with the healthy diet score (HDS) as the dependent variable. Even after adjustments for lifestyle habits and household circumstances, opportunities to be involved in meal preparation were positively correlated with the secondary indicators included in HDS. Furthermore, the changed HDS was higher in the group whose opportunities to be involved in meal preparation increased during the pandemic. Therefore, adopting opportunities to be involved in meal preparation may lead to a more balanced diet.</p>

<p><b>Objective:</b> To assess the feasibility of the draft Japanese Nutrient Profile (NP) model, we developed informational materials about its utilization, and conducted Internet research to identify issues and needs according to the motivation of behavioral change.</p><p><b>Methods:</b> We developed the informational materials (4 pages, 1 A3-sided sheet) based on the NP model, as well as materials from other countries. An online cross-sectional survey was conducted among 3,000 Japanese consumers aged 18 years or older. The age, sex, and regional distribution of the participants, as well as their motivation for behavioral change, were similar to those of the National census and the National Health and Nutrition survey, respectively. The participants read the informational materials and were asked how such materials would affect their food purchasing behavior. Based on the participants' current motivation for behavioral change, they were divided into three groups: not interested (<i>n</i> = 1,187), intend to improve (<i>n</i> = 1,465), and recognition of no problem with own eating behavior (<i>n</i> = 348).</p><p><b>Results:</b> More than 90% of the respondents found the informational materials easy to understand. The number of respondents who answered that the symbols that warned against overconsumption would influence their food purchasing behavior was greater for all food groups among the group with the intention to improve, accounting for approximately 70%, in contrast to only about 40% among those who were not motivated.</p><p><b>Conclusions:</b> Our results indicated that the food labeling based on the NP model might influence consumers' healthy eating behaviors, especially among those who intend to improve their eating behaviors.</p>

<p>A nutrient profile model (NP model) ranks foods according to their nutritional composition, allowing individuals to make well-informed dietary choices. In other countries, the application of NP models is reportedly associated with healthier food choices and health indicators. We examined a NP model applicable to the Japanese population for processed foods and preparing dishes. Considering the nutrition status of the Japanese population, we proposed that the model should target those aged 18 years or older. A category-specific model was adopted with setting thresholds to avoid overconsumption of total fat, saturated fat, sodium or salt equivalent, and energy for processed foods and prepared foods. We set the nutrient criteria for the proposed model and determined thresholds for each food category. In order to set the salt threshold for each dish, we conducted secondary analyses of the 2014‐2018 National Health and Nutrition Survey. The food groups according to dish type were compared between “high salt” consumers and “adequate” consumers. Furthermore, we conducted an online cross-sectional feasibility survey among 3,000 consumers. Here we describe the development procedure and feasibility of the proposed Japanese NP model to support the practice of healthy eating behavior.</p>

Language：English Publishing type：Research paper (scientific journal)
Our study examines differences in eating behaviour between day workers and rotating shift workers, and considers whether diurnal preference could explain the differences. Japanese female nurses were studied (39 day workers and 123 rotating shift workers, aged 21–63 years) using self-administered questionnaires. The questionnaires assessed eating behaviours, diurnal preference and demographic characteristics. Eating behaviours for rotating shift workers are associated with a more unbalanced diet and abnormal temporal eating patterns and that the associations may be explained by diurnal preference rather than by rotating shift work.

This cross-sectional study explored the prevalence of iron deficiency (ID) and associations between dietary factors and incidence of ID in female rhythmic gymnasts during preseason periods. Participants were 60 elite collegiate rhythmic gymnasts who were recruited every August over the course of 8 years. ID was noted in 48.3% of participants. Multiple logistic analysis showed that protein intake was significantly associated with the incidence of ID. Participants in the preseason’s weightloss periods showed a tendency toward insufficient nutrient intake and were at a high risk for ID, particularly because of lower protein intake.

This study examines the relationship between work schedule and BMI, and considers whether lifestyle habits could explain the relationship. Japanese female nurses (1179 day workers and 1579 rotating shift workers, aged 20-59) were studied using self-administered questionnaires. We found that higher consumption of sugar-sweetened beverages and shorter sleep duration were associated with rotating shift work and higher BMI. This should be taken into consideration in preventing obesity in real-life shift work situations.

PURPOSE:The purpose of this study was to investigate whether scheduling meals earlier in the day affects the circadian phase of the cardiac autonomic nervous system as assessed by heart rate variability (HRV) and serum lipid levels.
METHODS: Healthy men aged 21.4 ± 0.5 years (n = 14) with a habit of regularly skipping breakfast participated in this parallel trial involving altered feeding schedules. Participants in the early mealtime group (EM group, n = 8) were asked to eat three meals at 8:00, 13:00, and 18:00, and the control group (n = 6) ate at 13:00, 18:00, and 23:00 for 2 weeks. On the measurement day before and after intervention, fasting blood samples and 24-h electrocardiograph recordings were collected. Spectral analysis was used for approximate 10-min HRV segments. Low frequency (LF) power, high frequency (HF) power, and the ratio of HF to total power (%HF) were calculated to assess sympathovagal balance. Acrophases of the circadian rhythm of HRV variables were obtained by nonlinear least squares regression.
RESULTS: Triglyceride and total and LDL cholesterol levels were significantly decreased in the EM group when compared with the control group (p = 0.035, 0.008, and 0.004, respectively). Acrophases for HRV variables were advanced in the EM group and their difference between before and after the intervention in LF power (-3.2 ± 1.2 h) and %HF (-1.2 ± 0.5 h) reached significant level, respectively (p < 0.05).
CONCLUSIONS: Timing of meals was a key factor in regulating circadian phases of the cardiac autonomic nervous system and lipid metabolism. -

Circadian variation in cardiac autonomic nervous system activity and behavior during the day shifts of shift workers has not hitherto been clarified. This study examined diurnal 24-h variation in heart rate variability (HRV), sleep-wake cycle, physical activity, and food intake during the day shift in rotating shift workers. The subjects were female nurses and caregivers working at a health care facility (14 day workers and 13 rotating shift workers). Each subject was asked to undergo 24-h electrocardiograph and step count recordings. Coarse graining spectral analysis was used for approximately 10-min segments of HRV (600 beats) to derive the total power (TOT: >0.04 Hz), integrated power in the low-frequency (LF: 0.04-0.15 Hz) and high-frequency (HF: >0.15 Hz) ranges, the ratio of HF power to TOT (HF nu), and the ratio of LF power to HF power (LF/HF). Double cosinor analysis was used to obtain 24-h and 12-h period variations in variables of HRV and physical activity. While no difference was found in the acrophases of either period for step counts or in the 12-h period of HRV variables between the groups, the acrophases of the 24-h period for HRV variables were delayed by 1.3 to 5.5 h in rotating shift workers, and their differences in HF power, HF nu, and LF/HF reached a significant level (p < 0.05). On the days of the experiment, retiring time, waking up time, total time in bed, sleep efficiency, and mealtimes and energy intake for each diet did not differ between the groups. These results suggest that there is a possibility of an abnormal phase angle between circadian variation in cardiac autonomic nervous system activity and the sleep-wake cycle during the day shift in shift workers.

交代制勤務を伴う看護師及び介護士の食習慣と生活時間に関する実態を明らかにすることを目的として調査を行った。その結果、夜勤を含む交代制勤務者は、日勤勤務者よりも「菓子類」及び「嗜好飲料」の摂取量が多かった。また、交代制勤務者の生活時間は勤務形態によって異なり、夜勤入り日、夜勤明け日は日勤日と比較して朝食と昼食の欠食者が有意に多かった。さらに、交代制勤務経験年数とBMIの間には有意な正の相関が得られ、交代制勤務者における食習慣・生活時間とBMIは密接に関連することが示唆された。
