Urban-Rural Comparison of Nutrient Intake by Adult Women in Shaanxi Province, China

Triplet surveys were conducted in the city of Xi'an and two villages (one in the vicinity and the other at a distance) in Shaanxi fuvince in China in October-November (when agricultural activitis were low), 1997, to elucidate nutrient intakes with a focus on possible urban-rural differences. Total food duplicate samples were collected from non-smoking and non-habitually dhnking adult healthy women (ahout 50 subjects per site and 149 in total). The nutrient intakes were estimated from the weight of food items in reference to national food composition tables. On average, the women took 1873 kcal energy, 54 g protein and 37 g lipid per day, with a lipid eneny ratio of 18.4%. Both excess and insufficient energy intake was observed as a result of food intake analysis and body mass index determination. With regard to minor nutrient intakes, insufficiency was serious in the case of calcium, vitamin A and vitamin B2, but not with iron. Whereas dependency on plant foods for sources of energy and protein was common to the three regions, Xi' an people consumed more animal foods than those in the villages. Intake of fish and shellfish was quite low throughout the three regions. Among the four types of cereals, wheat was consumed most substantially in the three regions and in three meals (except for the village where people essentially did not take lunch in reflection of low agricultural activities), whereas rice was consumed more in Xi'an than in the two villages. Maize consumption was higher in the two villages (especially for breakfast) than in the city.In contrast, foxtail millet (although in small amounts) was taken primarily in Xi'an and ouly at the time of breakfast.

Nutrient Intake of Rural Households That Participated in a Farming System for Nutrition Study in India

Food based approach can prove effective in improving access and availability of nutrients from foods required for daily life where most of the people depend on agriculture for their livelihood. A study on feasibility of Farming Systems for Nutrition (FSN) approach was undertaken from 2013 to 2018 in a few villages of Koraput district, Odisha state and Wardha district, Maharashtra state in India. Interventions were done to increase crop diversity, intercropping of pulses and cereals, promotion of seasonal vegetables and fruits along with nutrition awareness. The endline survey showed increase in production diversity leading to improved household dietary diversity. This paper demonstrates the impact of FSN interventions on household nutrient intake. The results show that the intake of nutrients like protein, vitamin C, iron and calcium increased significantly in Koraput and all the nutrients including energy and vitamin A increased significantly in Wardha. The evidence shows that Farming System for Nutrition approach improves individual nutrient intake which in the long run can address the problem of undernutrition.

Certain Grain Food Patterns Are Associated with Improved 2015 Dietary Guidelines Shortfall Nutrient Intakes, Diet Quality, and Lower Body Weight in US Adults: Results from the National Health and Nutrition Examination Survey, 2005-2010

Objective: The goal of this study was to identify commonly consumed grain food patterns in US adults (≥19 years old;N = 14,384) and compare nutrient intakes, with focus on 2015-2020 Dietary Guidelines’ shortfall nutrients, diet quality, and health parameters of those consuming various grain food patterns to those not consuming grains. Methods: This study conducted secondary analyses of the National Health and Nutrition Examination Survey, 2005-2010. Cluster analysis was used and identified 8 grain patterns: 1) no consumption of main grain groups, 2) crackers and salty snacks, 3) yeast breads and rolls, 4) cakes, cookies, and pies, 5) cereals, 6) pasta, cooked cereals and rice, 7) quick breads, and 8) mixed grains. Results: Adults consuming “cereals”, “pasta, cooked cereals and rice”, and “mixed grains” had a better diet quality compared to no grains. Consuming many, but not all, of the grain food patterns resulted in less saturated fat and lower added sugars. Adults consuming “cereals”, “pasta, cooked cereals and rice” and “quick breads” had greater dietary fiber intake vs. no grains group. Calcium intake was increased in the cereals group, while magnesium intake was greater in adults consuming “cereals” and “pasta, cooked cereals and rice” vs. no grains. Vitamin D (D2 + D3) intake was higher in adults consuming “cereals”, “pasta, cooked cereals and rice”, and “mixed grains” vs. no grain group. Adults consuming “pasta, cooked cereals and rice” had lower body weights (79.1 ± 0.7 vs. 82.5 ± 1.2 kg;P = 0.009) and waist circumference (95.2 ± 0.6 vs. 98.2 ± 1.0 cm;P = 0.004) in comparison to those consuming no grains. Conclusions: Certain grain food patterns are associated with greater 2015-2020 Dietary Guidelines’ shortfall nutrients, better diet quality and lower body weights in adults. Additionally, certain grain food patterns are associated with lower intake of nutrients to limit, including saturated fat and added sugars.

Nutrient Intakes of Pregnant Women and their Associated Factors in Eight Cities of China： A Cross-sectional Study

Background： During tile last 3 decades, China has dramatic changes of the dietary pattern among its citizens, particularly in urban cities. This study aimed to determine the nutrient intake status and factors associated with nutrient intakes of urban Chinese pregnant women now-a-day. Methods： The multistage stratified random sampling method was applied in the cross-sectional study. 479 women in three trimesters of pregnancy from eight cities of China were recruited. Nutrient intakes were evaluated with one 24 h dietary recall, and compared with the Chinese Dietary Reference Intakes （DRIs） 2013 tbr available nutrients. Results： Most pregnant women had imbalanced macronutrient distribution with excessive energy derived from fat. Intakes of Vitamin A, B, calcium, magnesium, and selenium were below Chinese Recommended Nutrient Intake （RNI） and Estimated Average Requirements （EARs） in all trimesters. Most pregnant women took more tblic acid in the first trimester with a significant decrease in the second and third trimester （P 〈 0.05）. Shortfall in iron intake was tbund in the third trimester whereas some women may be at the risk of excessive iron intake. Intakes of thiamin met RNI in the first trimester but were below EAR in all trimesters. Trimester phasing was positively associated with most nutrients （P 〈 0.05）. Prepregnancy body mass index was inversely associated with energy, tht, Vitamin C, and calcium intake （P 〈 0.05）. Educational level and household income were positively associated with folic acid intake （P 〈 0.05）. Conclusions： Cunent prenatal dietary choices of urban pregnant women in China are imbalanced in the nutrient intake when compared with national DRIs 2013, particularly in intakes of energy derived from fat and micronutrients. Appropriate dietary advice to pregnant women should promote a balanced diet with emphasis on avoidance of foods of high fat content and incorporation of t＇oods that are good sources of the key micronutrients that are usually lacking in a regular pregnancy diet. Further research is needed to understand the eating habits and food patterns that contribute to this imbalanced diet in order to be able to effectively improve prenatal women＇s nutrient intake status.

Effects of different levels of urea supplementation on nutrient intake and growth performance in growing camels fed roughage based complete pellet diets

The utilization of urea in camels has beneficial and negative effects. The aims of this study were to investigate the effects of different levels of urea supplementation on nutrients intake, digestibility,growth performance, feed efficiency and economics in growing camels fed roughage based complete pellet diets. In the present study, eighteen growing camels with an average live body weight of306.17 ± 2.05 kg were randomly assigned in three treatments: T1 = roughage complete pellet diet without urea,T2 = T1 plus 1% urea,and T3 = T1 plus 2% urea. The results showed that the urea supplementation significantly affected average daily feed and nutrient intake of dry matter(DM), organic matter(OM), crude protein(CP), neutral detergent fiber(NDF), and acid detergent fiber(ADF)(P < 0.05).On the contrary, the average daily intake of nitrogen free extract(NFE) and water were not influenced by increasing urea supplementation(P > 0.05). Similarly, digestion coefficient of DM, CP, ether extract(EE),crude fiber(CF) and ADF was influenced by increasing urea level(P < 0.05), while the digestion coefficient of OM, NFE and NDF was not affected by increasing urea level(P > 0.05). The intake of digestive nutrients was similar among all treatment groups. Total body live weight gain and average daily gain were significantly higher in urea supplemented groups(P < 0.05) than in the control group. The supplementation of urea at 1% in low quality roughage complete pellet diets significantly improved(P < 0.05) the feed efficiency. In conclusion,these results indicated that the incorporation of urea at 1% in roughage based complete pellet diets could positively improve nutrients intake, digestibility, growth performance and feed conversion efficiency of growing camels.

Relatively High Bone Mineral Density in Chinese Adolescent Dancers Despite Lower Energy Intake and Menstrual Disorder

Objective The effect of dietary restriction, intense exercise and menstrual dysfunction on bone mineral density remains controversial. The aim of this study was to assess the skeletal health status and relationship between bone mineral density and nutrient intake, menstrual status, estrogen level and other factos in Chinese adolescent dancers. Methods Sixty dancers and 77 healthy controls underwent measurements of bone density, body composition, and estrogen level. Nutrient intake, menstrual status and physical activity were assessed with questionnaires. The correlation between these factors were analyzed. Results The dancers under study had a significantly lean body mass index （18.3±1.4 kg/m^2 vs. 21.7±3.1 kg/m^2）, lower percentage of body fat （0.25±0.05 vs. 0.34±0.04） and later age at menarche （14.0±0.9 y vs. 13.0±1.3 y）, and the estrogen level, daily calorie and fat intake in them were also lower than in the controls. All the dancers undertook intensive physical activity every day and up to 69% of them suffered from irregular menarche. Yet they had relatively high BMD and BMC of the total body and legs than the controls after adjusting for BM1 and age. Site-specific BMD was positively correlated to BMI, body composition and training hours per week and negatively correlated to the age at menarche and menstrual frequency. Conclusions The relatively high BMD and BMC of the dancers at the total body and legs were probably caused by high levels of weight-bearing physical activity. To ameliorate disordered eating, especially low energy intake might be helpful to prevent the Triad and to improve the bone health in adolescent dancers.

Comparison of dietary intakes of Canadian Armed Forces personnel consuming field rations in acute hot, cold, and temperate conditions with standardized infantry

Background:Dietary Reference Intakes are used to guide the energy intake of the Canadian Armed Forces(CAF)field rations provided to military personnel deployed for training or operations.However,the high energy expenditures likely to occur under harsh environmental/metabolically challenging deployment conditions may not be adequately considered.This study examined the Ad libitum energy and nutrient intakes of CAF personnel(n=18)consuming field rations in a resting thermoneutral environment and during a day of standardized strenuous infantry activities at varying environmental temperatures.Methods:Dietary intake was assessed using a measured food intake/food waste method during the experimental treatment and for 6 h after treatment.Four treatments were administered in a randomized counterbalanced design:exercise(as standardized infantry activities)in the heat(30℃),exercise in the cold(–10℃),exercise in temperate thermoneutral(21℃)air temperatures and a resting(sedentary)trial(21℃).Results:The average Ad libitum consumption of field rations was 70%of the provided total energy(2776±99 kcal/8 h)during all treatments.Even with an acute challenge of increased energy expenditure and temperature stress in the simulated field conditions,participants’energy intakes(1985±747 kcal/8 h)under hot,cold and temperate treatments did not differ from energy intake during the sedentary condition(1920±640 kcal/8 h).Participants’energy intakes(1009±527 kcal/6 h)did not increase during the 6 h posttreatment period when the stresses of the strenuous physical activities and the harsh environmental temperatures had subsided.Conclusions:These results should be considered when planning the provision of field rations for CAF personnel expected to be engaged in strenuous physical activities with prolonged exposure to temperature extremes.

Association of a Tobacco-specific Nitrosamine Carcinogen with Urinary Cotinine,Urinary Sodium Excretion,and Total Energy Intake in Adolescents and Children

This study investigated the association of a tobacco-specific nitrosamine carcinogen,4-(methylnitrosamino)-1-(3-pyridy1)-I-butanol(NNAL)with urinary cotinine(uCot),urinary sodium(uNa)excretion,systolic blood pressure(sBP),and total energy intake in adolescents and children in relation to the subjects'age.A total of 790 subjects aged 6-19 years were evaluated.NNAL,uCot,corrected NNAL(cNNAL),the NNAL/uCot ratio,uNa,sBP,and nutrient intake were measured.A strong association between uCot and cNNAL was observed in children who were 11 years of age(r=0.881,P<0.001);however,no significant association was noted in adolescents who were 19 years of age.The uNa level was significantly higher(133.9 mmol/L vs.107.8 mmol/L,P<0.001)and sBP was significantly lower(105.3 mmHg vs.110.6 mmHg,P=0.012)in adolescents with elevated NNAL than in those without elevated NNAL.NNAL was significantly higher in subjects with increased uNa excretion than in those without increased uNa excretion.NNAL was positively correlated with uNa(r=0.183,P<0.001)and negatively correlated with sBP(r=0.142,P<0.001).Non-smokers with elevated NNAL/uCot ratios had significantly lower total energy intake than those without elevated NNAL/uCot ratios(1729.0 kcal/day vs.1911.0 kcal/day,P=0.008).The relationship between NNAL and uCot varied according to the subjects'age.NNAL seems to play a role in decreasing sBP by enhancing uNa excretion.Insufficient nutrient intake may contribute to endogenous formation of NNAL in non-smoking adolescents and children.

Evaluation of Care Quality Related to Dietary Intake and Swallowing Functions of Residents at Long-Term Facilities in Japan

This study aimed to evaluate the quality of healthcare services pertaining to the dietary intake and swallowing functions of residents, nutrition management practices, and performance of residents at long-term care facilities. We investigated outcome indicators, such as changes in dietary intake and swallowing function levels of residents, and clarified which structural and process indicators were associated with the outcome indicators. This was a retrospective study, analyzing information on healthcare services from 1067 long-term care facilities during the fiscal year 2012, sampled from among those registered with the Welfare, Health and Medical Care Information Network of the Welfare and Medical Service Agency in Japan. Five outcome indicators were identified. Next, we examined the relationships between the outcome indicators and structural or process indicators using a multivariate linear regression model, adjusting for facility type. The findings showed how the five outcome indicators were used in long-term care facilities over a period of one year and determined the independent predictors of these outcome indicators. The amplification of dietary function 1 was associated with “assessment of oral functions using a feeding and swallowing assessment checklist every three months”, “holding care conferences related to ingestion and swallowing every three months”, and “maintaining a 1:2 ratio for meal-time assistants to residents”. To improve the quality of care, it is necessary to increase the number of staff (e.g., to provide meal assistance to residents) and to understand changes in the residents’ status through accurate assessment and monitoring.

Total Energy Expenditure of 16 Chinese Young Men Measured by the Doubly Labeled Water Method

Objective Doubly labeled water （DLW） method is the gold standard for measuring total energy expenditure （TEE）. We used this method to measure TEE in Chinese young men. Methods Sixteen healthy young men age 23±1 recruited. TEE was measured by the DLW method, by indirect calorimetry. We also conducted 24-h estimate energy requirements of the subjects. years with body mass index 22.0±1.4 kg/m2 were and basal energy expenditure （BEE） was determined activity, energy balance and factorial approach to Results TEE of subjects by DLW method was 9.45±0.57 M J/day （2258±180 kcal/day）. The 24-h activity was 10.80±0.33 M J/day （2582±136 kcal/day）. The energy requirement, derived from energy balance observations, was 9.93±1.32 M J/day （2373±315 kcal/day）. The BEE of 6.65±0.28 M J/day （1589±67 kcal/day）, calculated by the adjusted Schofield equation, was significantly higher （P〈O.O01） than that measured by indirect calorimetry, 5.99-±0.66 M J/day （1433-±158 kcal/day）. The TEE derived from the factorial approach was 10.31-±0.43 M J/day （2463±104 kcal/day）. Conclusion The TEE of Chinese young men measured by the DLW method was about 10% lower than the current recommended nutrient intake （RNI）, suggesting that the RNI for Chinese men maybe overestimated. Further studies are warranted to determine the value of the estimated energy requirement.

A Participant-assigned Interventional Research of Precesarean Internal Iliac Artery Balloon Catheterization for Managing Intraoperative Hemorrhage of Placenta Previa and Placenta Accreta Spectrum Disorders After Cesarean Section

Placenta accreta spectrum disorder (PASD) and placenta previa (PP) are two of the mosthideous obstetric complications which are usually associated with a history of cesarean section(CS). Moreover, women with PASD, PP and/or a cesarean scarred uterus are more likely to haveadverse pregnancy outcomes, including blood transfusion, hysterectomy, pelvic organs damage,postpartum hemorhage, disseminated intravascular coagulation, multi-organ dysfunction syndromeand even maternal or fetal death. This study aimed to investigate the efficacy of precesareaninternal iliac artery balloon catheterization (BC) for managing severe hemorhage caused by PASDand PP with a history of CS. This participant-assigned interventional study was conducted inTongji Hospital. We recruited 128 women with suspected PASD, PP and a history of CS. Womenin the BC group accepted precesarean BC of bilateral internal iliac arteries before the scheduledcesarean delivery. Women in the control group underwent a conventional cesarean delivery.Intraoperative hemorrhage, transfusion volume, radiation dose, exposure time, complicationsand neonatal outcomes were discussed. There were significant differences in calculated bloodloss (CBL) between BC group and control group (1015.0±144.9 vs. 1467.0±171.0 mL, P=0.04).Precesarean BC could reduce intraoperative red blood cell (RBC) transfusion as compared withcontrol group (799.5±136.1 vs. 1286.0±161.6 mL, P=0.02) and lessen the rate of using bloodproducts (57.1% vs. 76.4%, P=0.02). The incidence of hysterectomy was also lower in BC groupthan in control group. Postpartum outcomes showed no significant differences between the twogroups, except that postoperation hospitalization was longer in BC group than in control group(6.7±0.4 vs. 5.8±0.2 days, P=0.03). Precesarean BC of internal iliac artery is an effective methodfor managing severe hemorrhage caused by PASD and PP with a cesarean scarred uterus, as it couldreduce intraoperative blood loss, lessen intraoperative RBC transfusions and potentially decreasehysterectomies.

Performance and Haematological Characteristics of Broiler Finisher Fed Moringa oleifera Leaf Meal Diets

To investigate the effects ofMoringa oleifera leaf meal （MOLM） on the performance and haematology of broiler finisher using 120 Cobb chicks of 4 weeks old broiler chicks. The birds were assigned randomly into four dietary treatments containing MOLM at 0, 6%, 8%, and 10% （treatments 1, 2, 3 and 4） inclusion levels, respectively, in a complete randomized design experiment. The effect of the dietary treatments on the growth performance and blood parameters of the broiler finisher was determined. MOLM at a rate of 6% （T2）, 8% （T3）, and 10% （T4） of the diets （as fed basis） to replace 3.2%, 5.6% and 8.6% of the crude protein （CP） of the control diet. The daily feed, dry matter and CP intake of the chicks fed MOLM diets were higher （p〈0.05） than those fed the control diet. Average weight gain （AWG） of birds fed MOLM diets reduced as inclusion levels increases 09〈0.05） than those fed the control diet. Chicks fed T2 showed higher （p〈0.05） AWG than those on T3 and T4. Feed conversion ratios （FCR, weight gain/g and feed intake） were higher for chicks fed MOLM. MOLM showed minimal deleterious effects in birds. However, birds fed T2 （6%） diets recorded significantly （p〈0.05） the highest body weight gain. There were significant differences （p〈0.05） among groups in packed cell volume （PVC） of birds. The haemoglobin （Hb）, mean corpuscular volume （MCV）, mean corpuscular haemoglobin （MCH） and mean corpuscular haemoglobin concentration （MCHC） counts showed no significant difference （p〉0.05） among treatments. The results indicated that at 10% in the diets of broiler finisher chick, MOLM could be substituted with expensive conventional protein sources without any deleterious effects on performance and blood parameters of broiler finisher chicken.

Nutritional Status and Virological Outcomes of Children HIV Positive Attending Anti-Retroviral Clinic at University College Hospital, Ibadan

Malnutrition has been reported as a major factor contributing to the poor outcome of effective ART in HIV infection. This study aimed to describe the relationship between the nutritional status and virological outcome of the children attending the antiretroviral clinic at University College Hospital (UCH) Ibadan, Nigeria. Among the 159 (55.3% males and 44.7% females) children studied, almost half (42.8%) were orphans and the majority 56.6% were aged 120 - 180 months old. More than half (74.2%) had achieved viral suppression and significant associations were observed between viral load and stunting as well as between CD4 count and the age of the children (P < 0.05). The prevalence of stunting, wasting, and underweight was 27.7%, 9.4%, and 13.6% respectively. These indices reinforce the need for nutrition education and the provision of food supplements to improve the nutritional status of children infected with HIV.

Effects of supplementation of Brachiaria brizantha cv. Piatá and Napier grass with Desmodium distortum on feed intake,digesta kinetics and milk production in crossbred dairy cows

This study was planned to analyse the basis that make Brachiaria species with greater feeding value than Napier grass(Pennisetum purpureum) for lactating dairy cows.Forty lactating crossbred cows were stallfed on Brachiaria brizantha cv.Piata or Napier grass cv.French Cameroon supplemented(mixed on fresh matter basis) or unsupplemented with Desmodium distortum, a forage legume.All cows were fed on fresh matter basis under small-holder farming conditions.Results showed that B.brizantha cv.Piata had higher contents of dry matter(DM), crude protein(CP) and organic matter(OM), but lower contents of neutral detergent fibre(NDF) and acid detergent fibre(ADF) than Napier grass(P < 0.001).The legume supplementation increased intakes of CP and metabolizable energy(ME; P < 0.001), with higher effect on cows fed B.brizantha cv.Piata than on cows fed Napier grass.Average daily milk yield was lower on diets based on Napier grass than those based on B.brizantha cv.Piata(P < 0.001).The retention time of the particle phase of digesta in the digestive tract was longer on Napier grass(83.1 h) than on B.brizantha cv.Piata(62.8 h)(P < 0.05).It was concluded that in dairy cows, legume supplementation of B.brizantha cv.Piata increases nutrient intake, hence resulting in higher milk yields than supplementation of Napier grass.
