Sustainability Assessment of Rural Water Supply System

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to fulfill clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research is to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency which serves three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, shows that it meets the quality standards as raw water for drinking water. The aspect of water quantity is calculated to meet water needs for the next 20 years. The calculations results show that the daily average debit requirement is 17 L/s and the daily maximum debit is 19 L/s, while the existing debit is 15 L/s. The aspect of water continuity is calculated from the ability to distribute water during an emergency. The calculation results show that the distribution of clean water when there is no source of electrical energy can only be carried out in a maximum of 1 hour 13 minutes 48 seconds. The conclusion obtained is that the sustainability of the ‘Sugio’ Water Supply System from the aspect of water quantity and continuity still needs to be improved.

Protein Requirement Changes According to the Treatment Application in Neurocritical Patients.

Exploring protein requirements for critically ill patients has become prominent. On the other hand, considering the significant impact of coma therapy and targeted temperature management (TTM) on the brain as well as systemic metabolisms, protein requirements may plausibly be changed by treatment application. However, there is currently no research on protein requirements following the application of these treatments. Therefore, the aim of this study is to elucidate changes in patients' protein requirements during the application of TTM and coma therapy. This study is a retrospective analysis of prospectively collected data from March 2019 to May 2022. Among the patients admitted to the intensive care unit, those receiving coma therapy and TTM were included. The patient's treatment period was divided into two phases (phase 1, application and maintenance of coma therapy and TTM; phase 2, tapering and cessation of treatment). In assessing protein requirements, the urine urea nitrogen (UUN) method was employed to estimate the nitrogen balance, offering insight into protein utilization within the body. The patient's protein requirement for each phase was defined as the amount of protein required to achieve a nitrogen balance within ±5, based on the 24-hour collection of UUN. Changes in protein requirements between phases were analyzed. Out of 195 patients, 107 patients with a total of 214 UUN values were included. The mean protein requirement for the entire treatment period was 1.84±0.62 g/kg/day, which is higher than the generally recommended protein supply of 1.2 g/kg/day. As the treatment was tapered, there was a statistically significant increase in the protein requirement from 1.49±0.42 to 2.18±0.60 in phase 2 (p<0.001). Our study revealed a total average protein requirement of 1.84±0.62 g during the treatment period, which falls within the upper range of the preexisting guidelines. Nevertheless, a notable deviation emerged when analyzing the treatment application period separately. Hence, it is recommended to incorporate considerations for the type and timing of treatment, extending beyond the current guideline, which solely accounts for the severity by disease.

A review of the dietary diversity and micronutrient adequacy among the women of reproductive age in low- and middle-income countries.

The dietary quality of women of reproductive age (WRA) is particularly important during preconception, conception, and pregnancy for themselves and their offspring. Poorly diversified diets resulting in inadequate micronutrient consumption may have adverse effects on their health. This narrative review summarizes the findings of studies reporting on dietary diversity and micronutrient intake by WRA in low- and middle-income countries (LMICs). Studies on WRA aged 15-49 years in LMICs, with a sample size of more than 150, report dietary diversity and multiple micronutrient intake based on 24-h dietary recall/food weighed record/food frequency questionnaire, and published between January 2011 and June 2021 were included. The results were compared to the Food and Agriculture Organization (FAO) recommended cut-off for dietary diversity and the Indian Council of Medical Research (ICMR) recommended age- and sex-specific estimated average requirements (EARs) for micronutrient intake. This review includes 35 articles, of which 21 focused on dietary diversity and 14 on micronutrient intake. The results showed that WRA in LMICs had inadequate dietary diversity, with mean food group consumption of only 3.0-4.84, and around 42.3%-90% of women consumed inadequately diversified diets (<5 food groups). Additionally, most studies found that WRA did not consume adequate amounts of essential micronutrients, particularly calcium, iron, zinc, vitamin A, thiamin, riboflavin, folate, and vitamin B12. However, the intake of vitamin C, niacin, and vitamin B6 was above the required levels. In conclusion, this review highlights the common inadequacy of dietary diversity and multiple micronutrient intake among WRA in most LMICs. Effective measures involving improving dietary diversity, food fortification with micronutrients, and supplementation programs could help improve the dietary quality and intake of optimal micronutrients by women in LMICs.

Iron and zinc biofortification of rice by synergistic expression of OsNAS2 gene with monocot (Pennisetum glaucum) and dicot (Phaseolus vulgaris) ferritins

Iron and zinc deficiencies are the most prevalent cause of global hidden hunger. Rice, being one of the most consumed crops worldwide, is suitable to target for Fe and Zn biofortification. In present study, we generated rice transgenic lines to meet the recommended dietary requirement of iron and zinc through endosperm specific expression of dicot (kidney bean) and monocot (pearl millet) Ferritins along with constitutive expression of rice nicotianamine synthase 2 (OsNAS2) gene. Visualization through perls’ prussian staining and quantification by ICP-MS showed significant improvement in grain iron content in all the transgenic lines. The transgenic lines expressing any of the three selected gene combinations (PvFerrtin-OsNAS2, feedPgFerrtin-OsNAS2 and foodPgFerritin-OsNAS2), showed the potential to surpass the 30% of the estimated average requirement (13 μg/g Fe and 28 μg/g Zn) proposed for rice in HarvestPlus breeding program. Though the expression of PvFerritin along with OsNAS2 gene in IET10364 (indica) variety showed the best result, providing up to 4.2- and 3.5-fold increase in iron (30.56 μg/g) and zinc (60.1 μg/g) content, respectively; in polished grains compared to non-transgenic control. Thus, the lines developed in our study can be used for further breeding purpose to enhance the iron and zinc content in commercial rice varieties.

Simulating Potential Impacts of Solar MajiPump on the Economy and Nutrition of Smallholder Farmers in Sub-Humid Ethiopia

Irrigation is widely considered a potential means to improve agricultural productivity, nutrition, and income, as farmers can carry out farming and production year-round. However, the feasibility of irrigation technologies is highly dependent on the long-term economic return farmers achieve. Solar-based irrigation could address the challenges of underinvestment in irrigation within Africa. Evidence on the economic viability of the adopted solar pumps such as MajiPump is very scant and focused on ex post evaluation. This study evaluated the income and nutritional feasibility of solar-powered irrigation using the MajiPump in sub-humid Ethiopian highlands using the farm simulation (FARMSIM) model and compared it with the manual pulley system. Results from the FARMSIM model show that farmers’ adoption of Maji solar pump technology to grow vegetables is economically feasible with financial support such as credit or loan for initial and capital investment to acquire the pump. The average profit under the solar MajiPump, drip irrigation, and conservation agriculture was 3.6 times higher than that of the baseline scenario. While the pulley technology provides the same amount of irrigation water to grow vegetables, its feasibility is limited due to high labor costs and time, estimated to be more than seven times the baseline. The simulation results show that the alternative scenarios’ nutrition level has improved relative to other scenarios and met the minimum daily average nutrition requirement level for proteins, iron, and vitamin A but fell short in fat, calcium, and calories. The results suggest that farmers who adopt improved small-scale irrigation technologies (solar MajiPump and drip system) have a higher potential to increase production and income from irrigated crops and improve their nutrition if part of the income generated is used to purchase supplemental food for their nutrition.

The impacts of partial replacement of red and processed meat with legumes or cereals on protein and amino acid intakes: a modelling study in the Finnish adult population

Background A shift towards more plant-based diets is considered healthy and environmentally sustainable but may cause a concern regarding protein and amino acid intakes. This modelling study aimed to assess the impacts of partial replacement of red and processed meat with legumes or cereals on the protein and indispensable amino acid intakes in the Finnish adult population. Materials and methods We used the cross-sectional data of the National FinDiet 2017 Survey (two non-consecutive 24-h recalls, n = 1655, 47% men, aged 18–74 years). Six replacement scenarios were created in which the amount of red and processed meat exceeding 70 g/day (Finnish nutrition recommendation), or 30 g/day (EAT-Lancet recommendation) was replaced with the same amounts of legumes, cereals or their combination. Differences to the reference diet were evaluated based on non-overlapping 95% confidence intervals. Population shares (%) below estimated average requirements (EAR) were calculated using the usual intake modelling methodology (SPADE). Results The replacement scenarios decreased the protein and indispensable amino acid intakes depending on gender and age. At the 70-g level, decreases were observed only in men aged 18–64 years. At the 30-g level, decreases were observed in other gender and age groups except women aged 65–74 years. In the scenarios, the mean daily protein intake was 15–18% of total energy intake (E%) (reference 17–18 E%), and the proportions below the EAR were 7–10% in men and 8–10% in women aged 18–64 years (reference 5–7%) and 20–25% in men and 16–20% in women aged 65–74 years (reference 14–17%). For total indispensable amino acids, the proportions below the EAR were <5% in the reference diet and the scenarios. Conclusions The mean daily protein intake remained sufficient when red and processed meat was partially replaced with legumes or cereals in the Finnish adult population. However, protein adequacy in the elderly population warrants attention and more research.

Dependency on bamboo by local communities in various agro climatic zones of Madhya Pradesh in India

A study has been carried out in 12 Forest Divisions of 11 agro climatic zones from Madhya Pradesh (India) in which 1374 Basod household were surveyed. The present work revealed that maximum income contribution of Basod families from traditional business were found in districts of Malwa Plateau agro climatic zone (65.12%) followed by, Satpura Plateau (58.8%), Vindhya Plateau (50.71%), Central Narmada Valley (47.25%), Chhattisgarh Plains (46.48%), Northern hills regions of Chhattisgarh (45.49%), Nimad Plains (41.53%), Jhabua hills (41.59%), Kaimur Plateau &amp; Satpura hills (41.25%) whereas minimum contribution of Basod family annual income was found in Bundelkhand (38.79%) agro climatic zone. During the study it was observed that maximum number of consumption of bamboo for traditional business was found in districts of Bundelkhand zone (Average number of bamboo culms per annum is 421.6) whereas minimum number of consumption was observed in Satpura plateau (Average number of bamboo culms per annum is 171.6). Minimum average requirement of bamboo was found in Central Narmada Valley (657.6 culms per annum). This study revealed, cultivation of bamboo can be a profitable economy across the agro-climatic zones of Madhaya Pradesh, if proper coordination is maintained between farmers and traders.

Vitamin A - a scoping review for Nordic nutrition Recommendations 2023.

Vitamin A refers to a group of fat-soluble compounds with retinol activity, including all-trans retinol and pro-vitamin A carotenoids. Bioactive compounds include retinal and all-trans retinoic acid with important functions in vision, immune function, growth, and development. The literature search that was performed for the current scoping review yielded a total of seven publications relevant to setting the recommended daily intake for vitamin A. In total, six publications assessed the relationship of serum retinol and/or dietary vitamin A intake with fracture risk (n = 2), cancer (n = 3), and deficiency after bariatric surgery (n = 1). One additional report by the European Food Safety Administration (EFSA) with updated average requirements was included. The outcomes-based systematic reviews and meta-analyses showed positive associations for vitamin A intake and serum retinol with risk of hip fracture. Weak or inconclusive associations were observed for cancer or obesity. One publication by EFSA with updated estimated average requirements and population reference intakes for dietary vitamin A intakes was published in 2015. The EFSA recommendations and estimated average requirements are based on a European reference population, with body weights derived from an assumed body mass index of 22, which might be too low and not representative of the Nordic and Baltic populations, and consequently resulting in lower estimated average requirements and recommendations. In conclusion, there were limited new outcomes-based data for vitamin A and health outcomes.

PSX-10 Pilot Study Estimating Energy Expenditure in Dogs Using a Quantified Health Approach Indicates Potential to Improve Estimation of Energy Requirements

Abstract Over 50% of dogs in the USA are overweight or obese indicating that owners find it difficult to know how much food their dog needs. Feeding guidelines are based on the average energy requirements of dogs and do not take into account measured activity levels, which may lead to overfeeding by well-intentioned owners. The most common published energy prediction equation is (RER*AF) where RER is Resting Energy Requirement [70*(BW kg)0.75)] and AF is the Activity Factor, which generally ranges between 1 (body weight loss) and 8 (heavy work). This equation requires the user to estimate activity levels when selecting an AF, which may result in under- or overfeeding. The objective of this pilot study was to determine the ability of collar-worn activity monitors to more accurately predict the energy expenditure of dogs. Ten weight-stable beagles were group-housed at the Hill’s Pet Nutrition Center in Topeka, KS. Dogs were provided daily access to open, outdoor play space and human interaction; water was freely available. Dogs were weighed before feeding on days 1 and 5 of each of the 2 test periods. Accelerometer-based activity monitors were attached to the collars of the dogs on day 1 of each test period and activity was continually measured throughout the study using the activity monitor. Daily food consumption in grams was recorded and was converted to energy intake using the caloric density of the food. Daily energy requirements were calculated for each dog using the standard RER equation and either a standard AF of 1.6 or the estimated energy required for activity, in which newly established algorithms for quantification of walking, trotting, and running behaviors were paired with estimated caloric expenditure based on level of exertion (quantified health approach). The mean absolute error (MAE) of each method was calculated as the absolute value of the difference between the daily energy requirement vs. the daily caloric intake for each dog. The MAE was averaged across all dogs and all days for each of the two methods. The MAE ± SD of the standard RER and AF was 103 ± 126 kcal/day (Range -21.5 to 216 kcal/day). The MAE ± SD of the quantified health approach was 86 ± 90 kcal/day (Range -37.6 to 164.4 kcal/day). Both approaches resulted in normal MAE distributions. In this pilot study, quantifying energy expenditure using a wearable activity monitor reduced over-feeding by 16.5% compared with standard equations. In the future, energy predictions based on measured activity could result in more accurate feeding recommendations than traditional approaches. Future research aimed at optimizing energy predictions may help address the problem of pet obesity. This study was approved by the Hill’s Internal Animal Care and Use Committee. Funding: This study was funded by Hill’s Pet Nutrition, Inc.

Assessing the potential for healthier consumer food substitutions in Canada: population-level differences in dietary intakes of whole grains, refined grains, red meats, and legumes.

The potential for healthier consumer food substitutions is an important factor in the study of food environments, dietary choices, and population nutrition promotion. The burden of diet-related non-communicable diseases is unevenly distributed across Canada and variation in the food environment sub-nationally may be an important explanation. We used population-based 24 h dietary recall data from the 2015 Canadian Community Health Survey-Nutrition for Canadian adults (n=13 919) to examine dietary intakes of two food group pairings (whole grains/refined grains and legumes/red meats) where consumer substitutions have been recognized to be of importance in promoting healthy and sustainable population diet. We used an ANOVA followed by pairwise comparisons with Bonferroni correction to estimate differences in intakes between provinces for daily weight and proportion of total energy consumed. Based on the Global Burden of Disease Study, Canadians consumed below the average daily requirements of legumes and whole grains and well above the required range of red meat, suggesting room for broad improvements to population diet. Findings also demonstrate that there is potential for targeted shifts in dietary intakes among non-consumers of certain foods (e.g., legumes). This study may inform intervention development for the consumer nutrition environment including food accessibility and affordability to reduce non-communicable disease risk.

Exploring policy options to transform traditional dairy system in Ethiopia: A system dynamics approach

Despite having a larger herd size and a favourable climate, Ethiopia generally lags behind developing nations in terms of both production and consumption of dairy products. For the purpose of finding and assessing ways to increase milk production by the traditional dairy system in Ethiopia's West Shewa zone, we integrated system dynamics (SD) modelling with a participatory model building approach. The main objective of the research was to develop SD model for West Shewa dairy value chain and apply it to assess ex-ante milk production and dairy household profit impacts of various interventions. The interventions evaluated in the study include enhanced urea treatment of crops residue, increased production of improved feed, and investment in more dairy cows. Analysis reveals that policies targeting feed development can boost milk production and household profits above the baseline. They also lead to a higher seasonal variability in milk production. Through the feed development strategy producers can achieve a 70 % and 735 % increase in milk production and household profit, respectively. However, the implementation of improved feed policy still leaves a gap in the average feed protein requirement of a dairy cattle in the study area. On the other hand, policy of increasing cow herd is not profitable. In addition, improved feed policy in drought results in reduced herd size, yet it leads to a higher milk output and household profit. Hence, with the feed development options explored in this study, increasing herd size is not a recommended course of action for improvement of the West Shewa dairy value chain. Therefore, future research should explore for further enhancement of the supply as well as quality of feed resources and the potential of investment in improved breeds.

PSV-17 Threonine Requirements for Post-Weaning Pig in Individual Precision Nutrition Programs: a Meta-Analysis

Abstract Threonine (Thr) is generally the second limiting amino acid (AA) in growing pig diets, and it has a vital role in supporting intestinal functions and the immune system. Additionally, providing pigs with the correct AA requirements decreases nitrogen excretion and improves growth performance. This study aimed to determine standardized ileal digestibility (SID) Thr requirements for individual post-weaned pigs. Additionally, the Thr supplementation effect on average daily gain (ADG) of weaning and growing [7.3 – 51.5 kg of body weight (BW)] pigs under a sanitary challenge was evaluated. Eleven papers published from 1993 to 2015 composed the dataset used to determine the SID Thr requirement in the nursery phase, and five studies conducted from 2014 to 2020 composed the enteric sanitary challenge dataset. The SID Thr was obtained from publications when available or estimated based on the ingredient composition using EvaPig software. The average individual pig SID Thr requirements were estimated by bootstrapping 1,000 repetitions of a linear-plateau mixed model where all parameters were considered random as a function of the trial code. A general positive-definite matrix was used to represent the between-factors covariance using the nlme package of the R software. The effect of supplementing SID Thr above the requirement to attenuate ADG losses during a challenge was evaluated by an effect size analysis using a mixed model of the R Metafor package. Due to the low number of studies assessing pigs’ response to enteric challenges, a P &amp;lt; 0.25 was considered significant. In the post-weaning (14 kg average BW), the estimated ADG was 457 g/d (411 to 493 g/d) as a function of SID Thr individual requirement, which was 4.71 g/d for the average pig, with the least demanding pig requiring 4.4 g/d and the most demanding one requiring 5.1 g/d. For challenged pigs, the across-study heterogeneity was moderate (Higgs index = 36%). Increasing Thr intake by 18% above the estimated requirement attenuated (P = 0.15) ADG losses by 0.7 standard deviations (60 g) compared with pigs fed diets meeting Thr requirements. For pigs in individual precision feeding, the SID Thr requirement is estimated to be 1.03 g per 100 g of ADG for post-weaned pigs. The increase of SID Thr intake by 18% attenuated the ADG losses by 19% compared with non-supplemented pigs with enteric challenges.

The Influence of Lifestyle on High-Density Lipoprotein Concentration among Mexican Emerging Adults.

Previous studies have highlighted the role of lifestyle on HDL-C concentrations in adults. To our knowledge, the health and nutritional status of emerging adults have been understudied. The present study aimed to explore the most important lifestyle factors, including micronutrient intake adequacy and the percentage of energy from food processing, according to HDL-C concentrations in emerging adults. In this context, a cross-sectional analysis was conducted on 261 Mexican emerging adults who were apparently healthy. Lifestyle factors were collected through a structured survey and the prevalence of micronutrient intake inadequacy was estimated using the estimated average requirement cut-point method. The percentage of energy from ultra-processed foods was assessed using the NOVA system. HDL-C was determined using the enzymatic colorimetric method. Statistical analyses were conducted in SPSS. The results revealed that lifestyle factors do not differ according to HDL-C status. The participants showed a poor nutritional diet that was energy-dense and micronutrient-inadequate. Nearly half of their energy came from processed and ultra-processed foods. Most participants did not meet the recommendations for key nutrients (ϖ3 fatty acids and phytosterols) that promote a healthy lipid status. In conclusion, regardless of their HDL-C levels, emerging adults exhibited lifestyle-related risk factors. The persistence of these findings over time could contribute to the development of metabolic disorders in the future. It is crucial to increase understanding and to develop effective nutritional interventions during this critical phase of life.

Low micronutrient intake in nursing home residents, a cross-sectional study.

Low intake of micronutrients is associated with health-related problems in nursing home residents. As their food intake is generally low, it is expected that their micronutrient intake will be low as well. The nutrient intake of 189 residents (mean age 85.0 years (SD: 7.4)) in five different Dutch nursing homes was measured based on 3-day direct observations of intake. Micronutrient intake, without supplementation, was calculated using the Dutch food composition table, and SPADE software was used to model habitual intake. Intake was compared to the estimated average requirement (EAR) or adequate intake (AI) as described in the Dutch dietary reference values. A low intake was defined as>10% not meeting the EAR or when the P50 (median) intake was below the AI. Vitamin A, thiamin, riboflavin, niacin, B6, folate, B12, C, D, E, copper, iron, zinc, calcium, iodine, magnesium, phosphorus, potassium, and selenium were investigated. Our data showed that vitamin and mineral intake was low for most assessed nutrients. An AI was only seen for vitamin B12 (men only), iodine (men only), and phosphorus. A total of 50% of the population had an intake below the EAR for riboflavin, vit B6, folate, and vitamin D. For reference values expressed in AI, P50 intake of vitamin E, calcium, iodine, magnesium, potassium, and selenium was below the AI. To conclude: micronutrient intake in nursing home residents is far too low in most of the nursing home population. A "food-first" approach could increase dietary intake, but supplements could be considered if the "food-first" approach is not successful.

Assessment of calcium intake and recognition of calcium-rich food sources among the Saudi population.

Calcium is an essential mineral and one of the most prevalent in the body. Chronic insufficient calcium intake increases the risk of osteopenia, osteoporosis, and bone fracture. This study aimed to assess the Saudi population's calcium intake and knowledge of calcium sources as well as to identify factors associated with inadequate calcium intake. This cross-sectional study was conducted across Saudi Arabia using an online questionnaire distributed randomly through social media channels. The questionnaire was a validated tool that was previously developed and used by the original author to assess knowledge of calcium food sources and estimate calcium intake in the Saudi population. If an individual answered more than 11 questions correctly, calcium knowledge was considered adequate. Calcium intake was considered sufficient or insufficient based on the recommended dietary allowance (RDA) of 1000 mg/day. The survey included male and female Saudi citizens and residents aged 14 years or older. A total of 950 respondents aged 9-70 completed the questionnaire. A total of 62.9% of the respondents were 26-50 years old. Of the participants, 64.2% were female, 71.7% were married, and 61.9% had a diploma or a bachelor's degree. Of these, 63.8% were from the central region, and 97.6% were from Saudi Arabia. For those aged 9-18, the average calcium consumption was 577 mg/day, whereas it was 479 mg/day for those aged 19-50. The average intake was 479 mg/day for males aged 51-70 (EAR = 1000 mg/day) and 438 mg/day for females (EAR = 1200 mg/day). These calcium consumption values were significantly lower than the estimated average requirement (EAR) and RDA (p < 0.01). Correct response rates for the 19 calcium intake knowledge items ranged from 23.4 to 94.7%. Among the participants, 48.9% had significant calcium intake knowledge, as indicated by a score of > 11 out of 19 correct responses. Age, sex, marital status, educational attainment, and residence were significantly correlated with adequate knowledge of calcium. Demographic characteristics such as age, marital status, and residence were associated with sufficient calcium intake in the study. The study findings revealed that a significant proportion (51.1%) of participants demonstrated inadequate knowledge regarding calcium food sources. Additionally, the mean calcium intake was found to be lower than the RDA of 1300 mg/day for males and females 14-18 years old and 1000 mg/day for males and females 19-50 years old and males 51-70 years old; however, the RDA for females 51-70 years old is 1200 mg/day, suggesting an urgent need for interventions aimed at enhancing both calcium knowledge and intake.

Association between the Carbohydrate Quality Index (CQI) and Nutritional Adequacy in a Pediatric Cohort: The SENDO Project.

Suboptimal micronutrient intake in children remains a public health concern around the world. This study examined the relationship between a previously defined dietary carbohydrate quality index (CQI) and the risk of micronutrient intake inadequacy in a pediatric cohort of Spanish preschoolers. Children aged 4-5 years old were recruited at their medical center or at school, and information on sociodemographic, dietary, and lifestyle variables were collected through a self-administered online questionnaire. Dietary information was obtained from a validated 147-item semi-quantitative food frequency questionnaire. We calculated the CQI and categorized participants into quartiles according to their scores. We assessed the intakes of 20 micronutrients and evaluated the probability of intake inadequacy by using the estimated average requirement cut-off point. Generalized estimating equations were used to adjust for potential confounders and account for the intra-cluster correlations between siblings. The adjusted proportions of children with an inadequate intake of ≥three micronutrients were 23%, 12%, 11%, and 9% in the first, second, third, and fourth quartiles of the CQI, respectively. Children in the highest quartile of the CQI had 0.22-fold lower odds (95% CI 0.10-0.48) of having ≥three inadequate micronutrient intakes than their peers in the lowest quartile. These findings reinforce the relevance of carbohydrate quality in children's diets.

Sustainability Assessment of Rural Water Supply System in Lamongan, Indonesia

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to provide clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research was to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency, which served three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, met the quality standards for drinking water. The aspect of water quantity was calculated to meet water needs for the next 20 years. The calculation showed that the daily average debit requirement was 17 L/s and the daily maximum debit was 19 L/s, while the existing debit was 15 L/s. The aspect of water continuity was calculated by the ability to distribute water during an emergency. The calculation showed that the distribution of clean water when there was no source of electrical energy could only be carried out in a maximum of 1 hour, 13 minutes, and 48 seconds. The conclusion obtained was that the sustainability of the ‘Sugio’ Water Supply System from the perspective of water quantity and continuity needed to be improved.

Adjusting the Iodine Content of Iodized Salt to Meet the Recommended Intake for Females of Reproductive Age: A Simulation Study with a Reduced Sodium Scenario

BackgroundThe use of iodized salt is a key strategy to increase iodine intake worldwide. In many countries, including New Zealand, females of reproductive age are still at risk of being mildly iodine deficient. ObjectiveThis study aimed to determine the level of iodization of salt needed to ensure that females aged 18 to 40 y have an adequate intake of iodine in 2 scenarios: current discretionary salt intake and reduced discretionary salt intake. MethodData from nonpregnant, nonlactating females aged 18 to 40 y (n = 795) who took part in the 2008/09 New Zealand Adult Nutrition Survey and completed a 24-h dietary recall were used. Iodine intake was determined from all foods except bread and discretionary salt, which are fortified with iodine. Iodine from bread and salt was estimated at different levels of salt iodization, starting at 25 mg iodine/kg salt and increasing incrementally by 5 mg/kg, and added to calculate total iodine intake. The simulation concluded when the appropriate iodine content in salt was found using the estimated average requirement (EAR) cut-point method. ResultsIn the 2 scenarios, current discretionary salt intake (i.e., 400 mg/d) and reduced discretionary salt intake (i.e., 304 mg/d), the iodine concentration of salt is required to be 55 mg/kg and 70 mg/kg for no more than 2% of females to have an iodine intake below the EAR of 100 μg of iodine/d, respectively. In both scenarios and at all levels of iodine concentration, no one was above the upper level of intake of iodine of 1100 μg/d. ConclusionsThis study found that females of reproductive age need to consume iodized salt at the higher end of the legislated range of 25 to 65 mg/kg. If strategies to reduce sodium intake were adopted, the range would need to increase, or iodized salt would need to be included in a wider range of staple foods.

POTENSI RAINWATER HARVESTING DALAM MENGURANGI RISIKO KEKERINGAN DI KABUPATEN KARAWANG

&lt;p class="Abstract"&gt;&lt;em&gt;&lt;span lang="EN-US"&gt;Drought occurs quite often in Indonesia, closely related to water availability for community needs. One of the districts in West Java Province experiencing drought problems is Karawang district, where the RWH (Rainwater Harvesting) concept will be applied. This study aimed to analyze the risk of drought-related to applying the potential RWH in reducing drought risk. This study only focuses on meteorological drought, determined by SPI (Standardized Precipitation Index). Identification of potential areas for the application of RWH is carried out using the Weighted Method Overlay approach in the Geographic Information System (GIS), which was modified by adding a parameter of potential drought hazard. The potential reliability of RWH, as seen from Volumetric Reliability (VR) for supplying the average water requirement of MCK (Bath Washing Toilet) per year, indicates that most of the Karawang district area is potential for applying RWH. The results of adding the potential drought hazard parameters on applying the RWH concept show the decreasing area of very potential and potential category areas into 5,38%, the increase of drought resistance capacity is 17.5%, and the risk-reducing to 8.3%. Those results are due to the changes in the area of drought in the risk analysis. The assumptions of 60 rainy days on the average rainy day in a year and all households making RWH storage systems were used in the analysis. The results of this study can be used as a first step to see the potential of RWH in Karawang Regency both in terms of area and reliability.&lt;/span&gt;&lt;/em&gt;&lt;/p&gt;

Association between dietary vitamin intake and mortality in US adults with diabetes: A prospective cohort study.

To explore the association of dietary vitamin intake from food and/or supplement with mortality in US adults with diabetes. This prospective cohort study was conducted on 5418 US adults with diabetes from the National Health and Nutrition Examination Survey 1999-2018. Vitamin intake from food and supplements was estimated via dietary recall. Sufficient intake from food or food+supplement was defined as≥estimated average requirement (EAR) and≤tolerable upper intake level (UL), insufficient intake, <EAR; and excess intake, >UL. Medium supplementary intake was classified as>median level and ≤75th percentile; low intake,≤median level; and high intake, >75th percentile, as reported by supplement users. A total of 1601 deaths occurred among the participants over a median follow-up of 11.0years. Cox regression analysis of the single-vitamin model demonstrated that sufficient vitamin A and folate intake from food and food+supplement and medium vitamin A and folate intake from supplement; sufficient riboflavin, niacin, and vitamin B6 intake from food and food+supplement; and sufficient thiamin and vitamin E intake from food+supplement were significantly associated with reduced all-cause mortality (all p<0.05). In the multivitamin model, sufficient vitamin A and folate intake from food and food+supplement, medium vitamin A and folate intake from the supplement, and sufficient niacin intake from food and food+supplement were inversely associated with mortality (all p<0.05). Vitamin A and folate intake from food or supplement and niacin intake from food were significantly associated with reduced mortality in US adults with diabetes.
