RESUMO
Introduction: We sought to assess the Japanese diet by examining the current dietary intake in Japan using the global reference diet from the EAT-Lancet Commission (Planetary Health Diet; PHD), from the perspective of protein intake in different age groups. Methods: Average dietary intake by food group in the Japan National Health and Nutrition Survey 2019 (NHNS 2019) was converted to the PHD food groups, and the diet gap (DG) (%) of the global reference of the PHD was calculated by age group. Results: Although the DG of the intake was excessive compared with the global reference of the PHD in most food groups in all age groups (7.1-416%), the intake exceeded the upper limit of the range only for red meat (640%). Red meat had the highest DG among subjects in their 40s, although the DG decreased with increasing age. Protein intake was within the possible range and did not greatly exceed the recommended dietary intake in the Japanese standard. Discussion: The current Japanese diet contains an excessive intake of red meat in terms of the global reference of the PHD. This trend is similar to that previously reported in various western regions and countries. However, the Japanese diet does not significantly exceed the recommended protein intake for Japanese people, suggesting that the PHD is an environmentally friendly and healthy choice for younger and older age groups in an aging Japanese society. Policy makers need to develop sustainable and healthy food-based dietary guidelines in addition to providing food and nutrition education and developing a food environment that encourages sustainable and healthy choices to support dietary change.
RESUMO
BACKGROUND: Healthy diets that consider environmental pressures are required to meet sustainable development goals in Mongolia. This study aimed to clarify the extent of planetary and human health on Mongolian dietary intake. METHODS: The intake of eight food groups (g/day) was investigated using the national database of the Household socio-economic survey (HSES) 2019 in Mongolia. The boundary intake of the Planetary health diet (PHD) proposed by the EAT-Lancet Commission was considered 100% adequate. The adequacy (%) of food groups in the HSES were calculated in two areas (urban and rural), during the two seasons (cold and warm), and the total by each boundary of the PHD. The differences between the recommended dietary intake (RDI) in Mongolia and the PHD were also investigated in the same manner. RESULTS: The adequacy of red meat (i.e., beef, mutton, and horsemeat) in whole areas of Mongolia indicated more than 17 times higher intake (1,738%) than the PHD. The adequacy of vegetables (20%) and fruits (8%) in Mongolia indicated an intake shortage compared to the PHD. These discrepancies in dietary adequacy were greater in rural areas and during the cold seasons than in urban areas and during the warm seasons, respectively. The animal-based protein sources, especially red meat (1,091%), in the RDI of Mongolia were higher than those in the PHD. CONCLUSION: This study found a highly excessive intake of red meat and a low intake of vegetables and fruits compared with the PHD among Mongolian people, especially in rural areas and during the cold seasons. The limited diversity of food in severe geographic conditions, poor accessibility of food retailers, and insufficient nutrition education may have led to these results. Therefore, improvements in the food environment and nutritional education are required.
RESUMO
Objective: To assess if water from improved sources are microbiologically safe in Niassa province, Mozambique, by examining the presence of total coliforms in different types of water sources. Methods: We conducted a cross-sectional household survey in two rural districts of Niassa province during the dry season, from 21 August to 4 October 2019. We observed water sources and conducted microbiological water quality tests and structured household interviews. Findings: We included 1313 households, of which 812 (61.8%) used water from an improved source. There was no significant difference in presence of total coliforms between water sampled at improved and unimproved water sources, 62.7% (509 samples) and 65.7% (329 samples), respectively (P-value = 0.267). Households using improved water sources spent significantly longer time collecting water (59.1 minutes; standard deviation, SD: 55.2) than households using unimproved sources (49.8 minutes; SD: 58.0; P-value < 0.001). A smaller proportion of households using improved sources had access to water sources available 24 hours per day than that of households using unimproved sources, 71.7% (582 households) versus 94.2% (472 households; P-value < 0.001). Of the 240 households treating water collected from improved sources, 204 (85.4%) had total coliforms in their water, while treated water from 77 of 107 (72.0%) households collecting water from an unimproved source were contaminated. Conclusion: Current access to an improved water source does not ensure microbiological safety of water and thereby using access as the proxy indicator for safe drinking and cooking water is questionable. Poor quality of water calls for the need for integration of water quality assessment into regular monitoring programmes.

OBJECTIVE: The current study aimed to evaluate policies and actions for food environments by the Japanese Government using the Healthy Food Environment Policy Index (Food-EPI). DESIGN: Public health experts rated the extent of implementation of food environment-related Policy and the Infrastructure-support components, compared with international best practices. Subsequently, the experts proposed and prioritised future actions to address implementation gaps in an online workshop. SETTING: Japan. PARTICIPANTS: A total of sixty-six experts rated policy implementation by the Japanese Government and twenty-three participated in the workshop on future actions. RESULTS: The implementations of regulations on unhealthy foods and non-alcoholic beverages were rated low in the domains of Food composition, Food labelling and Food promotion, Food prices and Food retail in the Policy component. The implementations of several domains in the Infrastructure-support component were, overall, rated at a higher level, specifically for monitoring and intelligence systems. Based on the rating, reducing health inequalities by supporting people, both economically and physically, was the highest priority for future actions in both components. CONCLUSIONS: The current study found that Japan has a robust system for long-term monitoring of population health but lacks regulations on unhealthy foods and non-alcoholic beverages compared with international best practices. The current study confirmed the importance of continuous accumulation of evidence through national monitoring systems. Developing comprehensive regulations to restrict food marketing, sales and accessibility of unhealthy foods and non-alcoholic beverages is needed to improve the health of food environments in Japan.

ObjectivesãSocial security costs related to the healthcare and long-term care of patients with cardiovascular diseases is a national burden that is expected to grow as Japan's population ages. Nutritional policies for improving the nation's diet could prevent cardiovascular diseases, but scientific evidence on their costs and outcomes is limited. This study gives an overview of health economic evaluation studies on population-wide dietary salt-reduction policies that have been instituted for the purposes of cardiovascular disease prevention. Thus, this study provides background information for the development of evaluation methods that can be utilized in Japan for analyzing the effects of nutritional policies on public health and social security cost containment.MethodsãWe extracted representative health economic simulation models that are used for predicting the effects of cardiovascular disease-related interventions: Cardiovascular Disease Policy Model, IMPACT Coronary Heart Disease Policy and Prevention Model, US IMPACT Food Policy Model, Assessing Cost-Effectiveness (ACE) approach to priority-setting, and Prevention Impacts Simulation Model (PRISM). Next, we collected original articles on studies that used these models for assessing the costs and effects of national population-wide dietary salt-reduction policies. We then outlined the background, structure, and applied studies associated with each model.ResultsãThe five models utilized Markov cohort simulation, microsimulation, proportional multistate life tables, and system dynamics to predict the effect of dietary salt-reduction policies on blood pressure reduction and cardiovascular disease prevention. The models were applied to countries such as Australia, England, and the United States to simulate long-term (10 years to lifetime) costs and effects. These applied studies examined policies that included health promotion campaigns, sodium labels on the front of food packages, and mandatory or voluntary reformulation by the food industry to reduce the salt content of processed foods.ConclusionãHealth economic simulation modeling is actively being used to evaluate scientific evidence on the costs and outcomes of national dietary salt-reduction policies. Similarly, leveraging simulation modeling techniques could facilitate the evaluation and planning of dietary salt-reduction policies and other nutritional policies in Japan.

BACKGROUND: Despite an increasing need for multisectoral interventions and coordinations for addressing malnutrition, evidence-based multisectoral nutrition interventions have been rarely developed and implemented in low-income and middle-income countries. To identify key determinants of undernutrition for effectively designing a multisectoral intervention package, a nutrition survey was conducted, by comprehensively covering a variety of variables across sectors, in Niassa province, Mozambique. METHODS: A cross-sectional household survey was conducted in Niassa province, August-October 2019. Anthropometric measurements, anaemia tests of children under 5 years of age and structured interviews with their mothers were conducted. A total of 1498 children under 5 years of age participated in the survey. We employed 107 background variables related to possible underlying and immediate causes of undernutrition, to examine their associations with being malnourished. Both bivariate (χ2 test and Mann-Whitney's U test) and multivariate analyses (logistic regression) were undertaken, to identify the determinants of being malnourished. RESULTS: Prevalence rates of stunting, underweight and wasting were estimated at 46.2%, 20.0% and 7.1%, respectively. Timely introduction of solid, semi-solid or soft foods to children of 6-8 months of age was detected as a determinant of being not stunted. Mother-child cosleeping and ownership of birth certificate were a protective factor from and a promoting factor for being underweight, respectively. Similarly, availability and consumption of eggs at the household level and cough during the last 2 weeks among children were likely to be a protective factor from and a promoting factor for being wasted, respectively. CONCLUSION: Timely introduction of solid, semi-solid or soft foods could serve as an entry point for the three sectors to start making joint efforts, as it requires the interventions from all health, agriculture and water sectors. To enable us to make meaningful interprovincial, international and inter-seasonal comparisons, it is crucially important to develop a standard set of variables related to being malnourished.
RESUMO
BACKGROUND: Childhood stunting (height-for-age z-scores below - 2), a form of chronic undernutrition, remains a global health burden. Although a growing literature has examined the association between mothers' autonomy and childhood stunting, these studies have been limited to countries in South Asia or Sub-Saharan Africa where women have relatively lower social status than do men. Little research has analyzed the effect of mothers' autonomy on childhood stunting in Lao PDR, where women's social status is relatively high compared to that in other countries. METHODS: We conducted a cross-sectional questionnaire and body scale measurement targeting 100 mothers and their 115 children (<5 years old) from semi-urban communities in Lao PDR, which is the country with the highest prevalence of childhood stunting in the Indochina region. As dimensions of women's autonomy, we measured self-esteem, self-efficacy, decision-making power, freedom of mobility, and control of money. We then analyzed how each dimension was associated with the likelihood of childhood stunting. RESULTS: The likelihood of childhood stunting was significantly lower if mothers had higher self-efficacy for health care (OR = 0.15, p = 0.007), self-esteem (OR = 0.11, p = 0.025), or control of money (OR = 0.11, p = 0.041). In contrast, mothers' decision-making power and freedom of mobility were not significantly associated with childhood stunting. CONCLUSIONS: We clarified which dimensions of women's autonomy were associated with childhood stunting in Lao PDR. A closer examination of mothers' autonomy will aid proper understanding of the determinants of childhood stunting.

Smoking cessation efforts in Japan reduce smoking rates. A future zero-smoking policy would completely prohibit smoking (0% rate). We therefore analyzed the social welfare of smokers and non-smokers under a hypothetical zero-smoking policy. The demand curve for smoking from 1990 to 2014 was estimated by defining quantity as the number of cigarettes smoked and price as total tobacco sales/total cigarettes smoked by the two-stage least squares method using the tax on tobacco as the instrumental variable. In the estimation equation (calculated using the ordinary least squares method), the price of tobacco was the dependent variable and tobacco quantity the explanatory variable. The estimated constant was 31.90, the estimated coefficient of quantity was - 0.0061 (both, p < 0.0004), and the determinant coefficient was 0.9187. Thus, the 2015 consumer surplus was 1.08 trillion yen (US$ 9.82 billion) (95% confidence interval (CI), 889 billion yen (US$ 8.08 billion) - 1.27 trillion yen (US$ 11.6 billion)). Because tax revenue from tobacco in 2011 was 2.38 trillion yen (US$ 21.6 billion), the estimated deadweight loss if smoking were prohibited in 2014 was 3.31 trillion yen (US$ 30.2 billion) (95% CI, 3.13 trillion yen (US$ 28.5 billion) - 3.50 trillion yen (US$ 31.8 billion)), representing a deadweight loss about 0.6 trillion yen (US$ 5.45 billion) below the 2014 disease burden (4.10-4.12 trillion yen (US$ 37.3-37.5 billion)). We conclude that a zero-smoking policy would improve social welfare in Japan.

BACKGROUND: The global coverage rate of birth registration is only around 65% for the population of children under five although birth registration secures protection and access to health services that are fundamental rights for all babies. This study aimed to perform a basic analysis of the accessibility to birth registration to better understand how to improve the birth registration system in the Lao PDR. METHODS: For the analysis of birth registration and related socioeconomic factors, 9576 mother-child pairs were chosen from the data set of The Lao Social Indicator Survey 2011-12. After bivariate analysis with statistical tests including the chi-square test were conducted, logistic regression was performed to determine the variables that statistically influence accessibility to birth registration. RESULTS: Ethno-geographic factors and place of delivery were observed to be the factors associated with birth registration in this analysis. CONCLUSION: Many mothers in the Lao PDR deliver in their local communities. Therefore, capacity development of various human resources, such as Skilled Birth Attendant, to support the local administrative procedure of birth registration in their communities could be one option to overcoming the bottlenecks in the birth registration process in the Lao PDR.

BACKGROUND: Although the issue of nutrition was long underrepresented in the global health agenda, it regained international attention with the introduction of the Scaling Up Nutrition (SUN) framework. A historical review of global nutrition policies over 4 decades illustrates the evolution of nutrition policy themes and the challenges confronted by SUN. OBJECTIVE: This study reviews major events in global nutrition policy from the 1970s to the SUN movement around 2010 to illustrate the dynamics of global agenda setting for nutrition policy along with implications for the government of Japan. METHODS: The events are categorized according to each decade's nutrition paradigm: nutrition and its socioeconomic features in the 1970s, nutrition and community programs in the 1980s, nutrition as a political issue in the 1990s, and nutrition and evidence in the 2000s. RESULTS: This study identified 2 findings: First, the arguments that led to a global consensus on nutrition policy generated paradigm shifts in core ideas, and second, in response to these paradigm shifts, global nutrition policies have changed significantly over time. With regard to Japan, this analysis concludes that the government of Japan can take a greater initiative in the global health community as supporter of SUN by strategically developing a combination of financial, political, and practical approaches to improve global nutrition policy through the concepts of Universal Health Coverage and Human Security.

OBJECTIVES: The objective of this study is to gather statistical references on food safety education that encourages competence of food choice from the view-point of food safety. A survey on the involvement of the risk communication program on food safety in municipal governments and the attitude of local dietetics professionals towards the program was conducted. METHODS: In November, 2006, self-reported questionnaires were mailed to 1990 local dietetics professionals who worked in municipal governments in Japan. Descriptive statistics and cross tables were used for data analysis. RESULTS: 1162 questionnaires were mailed and 1130 available surveys were returned. Among the respondents, 41.5% answered that they inform the community about food safety, but 49.9% answered that they did not get information from the community. Most of the respondents answered that risk communication of food safety was important; 21.8% answered "extremely agree" and 62.3% answered "rather agree" on a scale of four from "extremely agree" to "do not agree". More than one-half of the dietetics professionals answered that their confidence in conducting risk communication was low; 20.5% answered "no confidence" and 52.5% answered "hardly have confidence" on a scale of four from "without confidence" to "with confidence". More than 80% of the respondents answered that they needed "professional knowledge" and "support from professional agencies". CONCLUSION: This study suggests that educating local dietetics professionals about professional knowledge on food safety, and obtaining support from special agencies will be essential in the upgrade of risk communication program on food safety in a community.
