The systematic review and meta-analysis were conducted to ascertain the prevalence of anemia, iron deficiency (ID), and iron deficiency anemia (IDA) among Chinese pregnant women. A total of 722 articles on maternal anemia during pregnancy published between January 2010 and December 2020 were compiled, and a systematic review and meta-analysis were conducted on 57 eligible studies including 1,376,204 pregnant women to ascertain the prevalence of anemia and the prevalence in different subgroups. The results showed that the prevalence of anemia, ID, and IDA among pregnant women in China were 30.7% (95% CI: 26.6%, 34.7%), 45.6% (95% CI: 37.0%, 54.2%), and 17.3% (95% CI: 13.9%, 20.7%), respectively. All prevalence increased with the progression of the pregnancy. There were sizable regional variations in the prevalence of anemia, ID, and IDA. Generally, lower prevalence was observed in the economically more advanced eastern region of the country, while the prevalence of ID was higher in the eastern region than that in the western region. The prevalence of anemia and IDA in rural areas was higher than that in urban areas, but ID prevalence was higher in urban areas. In conclusion, the regional differences and urban-rural disparities in the prevalence of anemia indicate the need for more context-specific interventions to prevent and treat anemia. It was found that dietary factors were one of the major causes of anemia, and iron-containing supplements and nutrition counseling could be effective interventions to reduce the prevalence of anemia, ID, and IDA among Chinese pregnant women.

OBJECTIVE: To estimate the strength of association between exposure to selected classes of prescribed medications and the risk of developing iron deficiency anaemia (IDA), specifically considering oral anticoagulants (OACs), antidepressants, antiplatelet agents, proton pump inhibitors (PPIs) and non-steroidal anti-inflammatories. DESIGN: A case-control study involving the analysis of community repeat prescriptions among subjects referred with IDA, and unmatched controls referred as gastroenterology fast-tracks for other indications. Multivariable logistic regression modelling was used to calculate ORs for the association between IDA presentation and each medication class, adjusted for age, sex and coprescribing. For those classes showing significance, it was also used to calculate risk differences between those in the IDA group with or without haemorrhagic lesions on investigation. RESULTS: A total of 1210 cases were analysed-409 in the IDA group, and 801 in the control group. Significant associations were identified between presentation with IDA and long-term exposure to PPIs (OR 3.29, 95% CI: 2.47 to 4.41, p<0.001) and to OACs (OR 2.04, 95% CI: 1.29 to 3.24, p=0.002). IDA was not associated with long-term exposure to any of the other three drug classes. In contrast to the relationship with PPIs, the association with OACs was primarily in the IDA sub-group with haemorrhagic lesions. CONCLUSION: Long-term exposure to PPIs and OACs are independently associated with the risk of developing IDA. There are grounds for considering that these associations may be causal, though the underlying mechanisms probably differ.

Iron deficiency is a widespread micronutrient deficiency, impacting over 30% of the global population. Iron Folic Acid supplement is recommended for pregnant women to counter iron deficiency anemia and neural tube anomalies. Although Iron Folic Acid supplementation is integral to Ethiopian antenatal care, one in four women in Ethiopia experiences anemia during pregnancy suggesting poor compliance. This study aimed to investigate compliance level and associated factors of Iron Folic Acid supplementation among pregnant women attending antenatal care in Wuchale Woreda of North Shoa Zone, Ethiopia. An institutional-based cross-sectional study was conducted among 302 pregnant women from March 20 to April 5, 2021, who were selected using a systematic random sampling technique. Data were collected through face-to-face interview, entered epi-data, and exported to Statistical Package for the Social Sciences for analysis. A multivariable logistic regression was used to identify factors associated with compliance level. All the results were presented with 95% confidence intervals. The compliance with Iron Folic Acid supplementation was 47.0%. Residing nearest to the health facility (AOR = 2.46; 95% CI 1.32, 4.57), initiating antenatal care at health center (AOR = 2.23; 95% CI 1.17, 4.51), having a family size of 4 and above (AOR = 4.99; 95% CI 2.43, 10.24), and receiving information from health extension workers (AOR = 5.52; 95% CI 1.30, 23.54) increased compliance with Iron Folic Acid supplementation. Less than half of the pregnant women were compliant with Iron Folic Acid utilization. There is a need to prioritize promoting the importance of Iron Folic Acid supplementation through health education particularly by targeting pregnant women with identified factors.

Importance: The prevalence of iron deficiency varies widely according to how it is defined. Objective: To compare the prevalence of iron deficiency among women using 3 different definitions. Design, Setting, and Participants: The cross-sectional Hemochromatosis and Iron Overload Screening Study (HEIRS; 2000-2006) evaluated the prevalence, determinants, and outcomes of hemochromatosis and other iron-related disorders. Multiethnic, primary care-based screening (2001-2003) was performed at 5 field centers (4 in the US and 1 in Canada). Volunteer women aged 25 years and older were recruited at primary care venues associated with the field centers. Data were analyzed from June to December 2023. Main Outcomes and Measures: Measures included transferrin saturation, serum ferritin level, and self-reported age, pregnancy, and race and ethnicity. Three iron deficiency definitions were studied: (1) combined transferrin saturation less than 10% and serum ferritin less than 15 ng/mL (HEIRS), (2) serum ferritin less than 15 ng/mL (World Health Organization [WHO]), and (3) serum ferritin less than 25 ng/mL (a threshold for iron-deficient erythropoiesis [IDE]). Results: Among 62 685 women (mean [SD] age, 49.58 [14.27] years), 1957 women (3.12%) had iron deficiency according to the HEIRS definition, 4659 women (7.43%) had iron deficiency according to the WHO definition, and 9611 women (15.33%) had iron deficiency according to the IDE definition. Among 40 381 women aged 25 to 54 years, 1801 women (4.46%) had iron deficiency according to HEIRS, 4267 women (10.57%) had iron deficiency according to WHO, and 8573 women (21.23%) had iron deficiency according to IDE. Prevalence rates of iron deficiency among 2039 women aged 25 to 44 years who reported pregnancy were 5.44% (111 women) according to HEIRS, 18.05% (368 women) according to WHO, and 36.10% (736 women) according to IDE. Iron deficiency prevalence by the 3 respective definitions increased significantly in each racial and ethnic group and was significantly higher among Black and Hispanic participants than Asian and White participants. The relative iron deficiency prevalence among the 62 685 women increased 2.4-fold (95% CI, 2.3-2.5; P < .001) using the WHO definition and increased 4.9-fold (95% CI, 4.7-5.2; P < .001) using the IDE definition. Conclusions and Relevance: Three definitions of iron deficiency were associated with significantly different prevalence of iron deficiency in women, regardless of self-reported age, pregnancy, or race and ethnicity. Using higher serum ferritin thresholds to define iron deficiency could lead to diagnosis and treatment of more women with iron deficiency and greater reduction of related morbidity.

AIM: To investigate iron-deficiency anemia as a risk factor for dental pulp disease in children from the central Peruvian jungle. METHODOLOGY: A case-control study was carried out with 270 children, of which 90 referred to cases and 180, to controls. Patients with pulp disease were diagnosed according to the criteria of the Association of Endodontists and the American Board of Endodontics. A specific questionnaire was used to assess ferrous sulfate consumption, maternal education level, maternal age, occupation, and household income. Data were analyzed using Pearson's correlation coefficient and a binary logistic regression. RESULTS: Iron deficiency anemia offers a risk factor for pulp disease in children (OR 7.44, IC 95% 4.0-13.8). According to multivariate analysis using binary logistic regression, ferrous sulfate consumption (OR 13.8, IC 95% 5.6.33.9), maternal education level (OR 2.4, IC 95% 1.1-5.3), maternal age (OR 7.5, IC 95% 2.9-19.4), household income (OR 4.0, IC 95% 1.6-9.6), and caries (OR 10.7, IC 95% 4.5-25.7) configured independent factors that were statistically associated with pulp disease. CONCLUSION: Iron deficiency anemia, ferrous sulfate consumption, maternal education level, maternal age, household income, and dental caries were positively associated with pulp disease in children.

BACKGROUND: Iron deficiency (ID) has been reported in patients with congenital heart disease. There is, however, a scarcity of data on its prevalence in patients with a Fontan circulation. The aim of this study is to investigate the prevalence of ID in Fontan patients and to investigate the association between ID and exercise capacity in this population. METHODS AND RESULTS: Blood count and haematological parameters were determined in plasma of 61 Fontan patients (51% female, mean age 29±9 years). ID was defined as transferrin saturation (TSAT) ≤19.8%. The prevalence of ID was 36% (22/61 patients). Especially among women, the diagnosis of ID was highly prevalent (52%) despite normal haemoglobin levels (153.7±18.4 g/L). Mean ferritin levels were 98±80 µg/L and mean TSAT levels were 22%±12%. Cardiopulmonary exercise testing was performed in 46 patients (75%). Patients with ID had a lower peak oxygen uptake (V̇O2peak) (1397±477 vs 1692±530 mL/min; p=0.039), although this relationship was confounded by sex. The presence of ID increased the likelihood of not achieving a respiratory exchange ratio (RER) ≥1.1 by 5-fold (p=0.035). CONCLUSION: ID is highly prevalent among patients with a Fontan circulation. V̇O2peak is lower in patients with ID. Fontan patients with ID are less likely to achieve an RER≥1.1 during cardiopulmonary exercise testing.

The prevalence of anaemia in India remains high in children, especially those in rural areas, and in women of childbearing age, and its impairment of neurological development can have serious lifelong effects. It is concerning that the most recent official data (2019-21) indicate an increased prevalence compared with 2015-16. There is also considerable variability in childhood anaemia between Indian states with socioeconomic factors, such as wealth and education contributing to the risk of anaemia among adolescent women and their children. Dietary iron deficiency is often regarded as the main contributor to anaemia but increasing evidence accumulated from the authors' ongoing literature database coupled with recent literature research suggests that it has a multifactorial aetiology, some of which is not related to nutrition. This narrative review focused on these multifactorial issues, notably the contribution of vitamin B12/folate deficiency, which also has a high prevalence in India. It was also noted that the dietary intake of bioavailable iron remains an important contributor for reducing anaemia, and the role of millets as an improved iron source compared to traditional staple cereals is briefly discussed. The overall conclusion is that anaemia has a multifactorial aetiology requiring multifactorial assessment that must include assessment of vitamin B12 status.

In pregnant women with multiple infections, nutrient deficiencies, and inflammation (MINDI), the study of anemia and iron status is limited. For this cross-sectional study (n = 213 Panamanian indigenous women), we investigated if hemoglobin, anemia (Hb < 110 g/L), ferritin, serum iron, serum transferrin receptor, and hepcidin were associated with (1) maternal nutritional status and supplementation practices, (2) biomarkers of inflammation, and (3) presence/absence of infections. Hierarchical generalized linear and logistic regression models and dominance analyses identified the relative importance of these predictors. Anemia (38%), which was likely underestimated due to low plasma volume (95%), was associated with lower ferritin, vitamin A, and weight-for-height, suggesting anemia of undernutrition. Inflammation was not associated with Hb or anemia; nevertheless, higher CRP was associated with increased odds of low serum iron and higher ferritin and hepcidin, indicating iron restriction due to inflammation. The length of iron supplementation did not enter models for anemia or iron indicators, but a multiple nutrient supplement was associated with higher ferritin and hepcidin. Moreover, iron supplementation was associated with higher odds of vaginal trichomoniasis but lower odds of caries and bacterial vaginosis. The complex pathogenesis of anemia and iron deficiency in MINDI settings may require other interventions beyond iron supplementation.

BACKGROUND: Anemia remains a major global public health issue, affecting around 24.8% of the world's population in both developing and developed countries. Pregnant women in developing countries are particularly susceptible, with 38.2% affected worldwide. Anemia is also a major contributor to maternal mortality, with 510,000 maternal deaths globally, of which 20% occur in developing countries and are related to anemia. Iron deficiency anemia is the most prevalent form, impacting 1.3 to 2.2 billion individuals, with 50% being women of reproductive age. AIM: This study aimed to assess the prevalence and associated factors of anemia in pregnant women attending antenatal care (ANC) at Hargeisa Group Hospital (HGH), Somaliland. METHODS: A cross-sectional study included 360 pregnant women, who sought ANC at HGH from July 15 to August 6, 2023. The study subjects were selected using systematic random sampling. Data were collected through structured questionnaires and participants' current medical charts, including hemoglobin levels. Data analysis was performed using SPSS software (version 20). RESULTS: The study revealed an overall prevalence of anemia among pregnant women at 50.6% (95% CI: 45.40 - 55.72%). Anemia severity was categorized as mild (33.0%), moderate (54.9%), and severe (12.1%). Factors statistically associated with anemia included gestational age in the third trimester (AOR = 3.248, 95% CI: 1.491-7.074), lack of ANC visits (AOR = 6.828, 95% CI: 1.966-23.721), and absence of iron supplementation (AOR = 29.588, 95% CI: 2.922-299.713). Notably, a higher consumption of meat per week was associated with a reduced risk of anemia (AOR = 0.198, 95% CI: 0.104-0.379). CONCLUSION: The study underscores the severity of anemia in pregnant women within the range considered as severe public health problem by WHO. It is crucial to emphasize effective prenatal care, improve dietary practices, and promote the provision of iron supplements. Enhanced maternal education on Anemia during ANC visits has the potential to reduce Anemia prevalence and mitigate adverse maternal and neonatal outcomes.

Anemia in breastfeeding women is a neglected global health issue with significant implications for maternal and child health. Despite its widespread occurrence and adverse effects, this problem remains largely unknown and overlooked on the global health agenda. Despite efforts to improve health access coverage and provide iron and folic acid supplementation, anemia persists. This underscores the need for a comprehensive approach to address the problem. Urgent action must be taken to prioritize education and awareness campaigns, ensure access to nutritious food, and enhance healthcare services. Education programs should focus on promoting iron-rich diets, dispelling cultural myths, and providing practical guidance. Improving healthcare services requires increasing availability, ensuring a consistent supply of iron supplements, and providing adequate training for healthcare providers. A successful implementation relies on a strong collaboration between the government, healthcare providers, and community. It is crucial that we acknowledge that high coverage alone is insufficient for solving the issue, emphasizing the importance of targeted interventions and a strategic implementation. By adopting a comprehensive approach and addressing the underlying causes of anemia, Indonesia can make significant progress in reducing its prevalence and improving the overall health of its population, particularly among breastfeeding women.

INTRODUCTION: The prevalence of iron deficiency and anemia in the setting of modern-day maintenance immunosuppression in pediatric heart transplant (HTx) recipients is unclear. The primary aim was to determine the prevalence of iron deficiency (serum ferritin < 30 ng/mL ± transferrin saturation < 20%) and anemia per World Health Organization diagnostic criteria and associated risk factors. METHODS: Single-center, cross-sectional analysis of 200 consecutive pediatric HTx recipients (<21 years old) from 2005 to 2021. Data were collected at 1-year post-HTx at the time of annual protocol biopsy. RESULTS: Median age at transplant was 3 years (IQR .5-12.2). The median ferritin level was 32 ng/mL with 46% having ferritin < 30 ng/mL. Median transferrin saturation (TSAT) was 22% with 47% having TSAT < 20%. Median hemoglobin was 11 g/dL with 54% having anemia. Multivariable analysis revealed lower absolute lymphocyte count, TSAT < 20%, and estimated glomerular filtration rate <75 mL/min/1.73 m2 were independently associated with anemia. Ferritin < 30 ng/mL in isolation was not associated with anemia. Ferritin < 30 ng/mL may aid in detecting absolute iron deficiency while TSAT < 20% may be useful in identifying patients with functional iron deficiency ± anemia in pediatric HTx recipients. CONCLUSION: Iron deficiency and anemia are highly prevalent in pediatric HTx recipients. Future studies are needed to assess the impact of iron deficiency, whether with or without anemia, on clinical outcomes in pediatric HTx recipients.

Iron deficiency anemia is a public health problem among adolescents that could be addressed by weekly Iron Folic Acid Supplementation (IFAS). The Ethiopian government piloted weekly IFAS in schools, where its effectiveness depends on compliance. We assessed the determinants of compliance with the weekly IFAS in Ethiopia. A school-based survey was conducted in 506 adolescent girls on weekly IFAS. Compliance was considered when girls reported WIFAS for at least three months without discontinuation. Bivariable and multivariable logistic regression models were modeled, with odds ratios reported. Out of 506, 25.8% had limited access to educational resources, and 79.4% had no information on IFAS. Among these, 47.9% (95% CI: 45.5-49.9%) had poor compliance with weekly IFAS. Non-compliance was mainly due to school absenteeism (55.9%). Important predictors of poor compliance were adolescent girls' marital status (AOR = 5.21; 1.55-17.6), academic standing (AOR = 4.37; 2.20-8.70), family income (AOR = 1.85; 1.09-3.15), access to health education materials (AOR = 1.57; 1.02-2.40), problems with IFAS (AOR = 2.44; 1.26-4.74), a discouraging home environment for the program (AOR = 2.27; 1.54-3.34), and a lack of knowledge of the IFAS program (AOR = 1.40; 0.97-2.03). Compliance with weekly IFAS is optimal, which could be improved via strong adherence support and feasible supplementation schedules.

BACKGROUND: Iron deficiency anemia (IDA) is a global health challenge, especially affecting females and children. We aimed to conduct an umbrella systematic review of available evidence on IDA's prevalence in Iranian pregnant women and children. METHODS: We searched the Web of Science, Science Direct, PubMed, Scopus, and Google Scholar databases for articles published by April 2023. Meta-analyses investigating the status of IDA in Iran were included. The findings of seven meta-analyses comprising 189,627 pregnant women with a mean age of 26 and 5,890 children under six years old were included in this study. The methodological quality of each study was evaluated with the Assessment of Multiple Systematic Reviews (AMSTAR2) instrument. RESULTS: We estimated the prevalence of IDA at 15.71% in pregnant women and 19.91% in young children. According to our subgroup analysis of pregnant women, IDA's prevalence in urban and rural regions was 16.32% and 12.75%; in the eastern, western, central, southern, and northern regions of Iran, it was estimated at 17.8%, 7.97%, 19.97%, 13.45%, and 17.82%, respectively. CONCLUSION: IDA is common in young children and pregnant females and is a significant public health concern in Iran. The present umbrella review results estimated that Iran is in the mild level of IDA prevalence based on WHO classification. However, due to sanctions and high inflation in Iran, the prevalence of anemia is expected to increase in recent years. Multi-sectoral efforts are required to improve the iron status of these populations and reduce the burden of IDA in the country.

Objective: To evaluate vitamin D deficiency in children with iron-deficiency anaemia, and to identify the risk factors for such deficiency. METHODS: The cross-sectional study was conducted at the Children's Hospital, Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from October 2021 to March 2022, and comprised children aged 1-5 years who had been diagnosed with iron-deficiency anaemia. Quantitative variables, like age, height, weight, gender, socioeconomic status and sibling status, were controlled by stratification. Data was compared to assess the risk factors of vitamin D deficiency among the subjects. Data was analysed using SPSS 22. RESULTS: Of the 236 children with iron-deficiency anaemia, 159(67.5%) also had vitamin D deficiency; 95(59%) girls and 65(41%) boys. Overall, 104(65.4%) subjects were aged 4-5 years and 55(34.6%) were aged 1-3 years. Vitamin D deficiency had significant association with female gender, older age, height and weight <5th centiles, educated parents, low to middle socioeconomic status, urban residence and higher number of siblings (p<0.05). CONCLUSIONS: The prevalence of vitamin D deficiency among children with iron-deficiency anaemia was found to be high.

OBJECTIVES: Iron deficiency, anaemia, and menorrhagia - or heavy menstrual bleeding - are interrelated conditions that are highly prevalent and commonly underrecognised in exercising females of reproductive age. This study utilised a screening tool to identify risk factors and symptoms associated with heavy menstrual bleeding, iron deficiency, and anaemia in this population. DESIGN: An observational, cross sectional survey study was employed. METHODS: 1042 active females (aged 18-65) completed a comprehensive screening questionnaire and 887 (85 % compliance) provided a fingerprick blood sample for haemoglobin (Hb) concentration measurement. Women that presented as anaemic (defined as a [Hb] < 120 g/L) or deemed to be at risk of iron deficiency (120 < [Hb] < 130 g/L) were asked to complete follow-up blood tests to screen for iron studies. RESULTS: Average [Hb] was 134.2 ±â€¯12.1 g/L, with 94 individuals considered anaemic (10.6 %). Of the sample, 104 underwent follow-up blood tests; 51 (~49 %) presented with iron deficiency (defined as ferritin <30 µg/L). Based on survey responses, 274 (30.9 %) participants were determined to have heavy menstrual bleeding. Those presenting with heavy menstrual bleeding were younger, exercised fewer hours per week, and were more likely to have a history of iron deficiency or anaemia (all p < 0.05). Participants reporting a history of anaemia or iron deficiency were more likely to have heavy menstrual bleeding (anaemia: 39.7 %; iron deficiency; 36.9 %; both p < 0.05). CONCLUSIONS: In this cohort of exercising females of reproductive age, the prevalence of anaemia was 10.6 %. There is a strong association between heavy menstrual bleeding and a self-reported history of iron deficiency and anaemia. Greater awareness of heavy menstrual bleeding and its relationship with iron deficiency and anaemia is needed in this population. Non-invasive screening should be conducted to raise awareness and further understand the associated risk factors and symptomatology.

Iron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.

Celiac disease is a growing global public health concern. This epidemiological study is aimed at determining the prevalence of celiac disease in Kermanshah, Western Iran, from 2019 to 2021, as well as the frequency of gastrointestinal and nongastrointestinal manifestations associated with the disease. In this cross-sectional study, the medical records of all patients with a confirmed diagnosis of celiac disease between 2019 and 2021 were reviewed. The average population during the study period was 2,058,545. A researcher-developed checklist was used as the data collection tool, and descriptive statistics were employed for data analysis. During the study period, there were 113 patients diagnosed with celiac disease, with a mean age of 29.1 ± 16.6 years. The three-year prevalence of celiac disease was 5.49 (95% CI: 5.17-5.82) per 100,000 population. Among these patients, 70% (n = 78) was female. The most common gastrointestinal manifestations of the disease were abdominal pain (77.8%), constipation (59.3%), and diarrhea (54.9%). Iron-deficiency anemia (64.6%) and vitamin D3 deficiency (46.1%) were the most common nongastrointestinal manifestations. Growth retardation was observed in 39.0% of patients. This study demonstrated a higher prevalence of celiac disease in Kermanshah compared to global statistics. Given the association of celiac disease with other conditions such as diabetes, irritable bowel syndrome, growth retardation, and iron-deficiency anemia, healthcare providers should consider screening patients for celiac disease. Furthermore, community-based education is crucial in raising awareness about the significance of adhering to a proper diet and reducing wheat consumption.

Objective: To understand the current status of anemia, iron deficiency, and iron-deficiency anemia among preschool children in China. Methods: A cross-sectional study was conducted with a multi-stage stratified sampling method to select 150 streets or townships from 10 Chinese provinces, autonomous regions, or municipalities (East: Jiangsu, Zhejiang, Shandong, and Hainan; Central: Henan; West: Chongqing, Shaanxi, Guizhou, and Xinjiang; Northeast: Liaoning). From May 2022 to April 2023, a total of 21 470 children, including community-based children aged 0.5 to<3.0 years receiving child health care and kindergarten-based children aged 3.0 to<7.0 years, were surveyed. They were divided into 3 age groups: infants (0.5 to<1.0 year), toddlers (1.0 to<3.0 years), and preschoolers (3.0 to<7.0 years). Basic information such as sex and date of birth of the children was collected, and peripheral blood samples were obtained for routine blood tests and serum ferritin measurement. The prevalence rates of anemia, iron deficiency, and iron-deficiency anemia were analyzed, and the prevalence rate differences were compared among different ages, sex, urban and rural areas, and regions using the chi-square test. Results: A total of 21 460 valid responses were collected, including 10 780 boys (50.2%). The number of infants, toddlers, and preschoolers were 2 645 (12.3%), 6 244 (29.1%), and 12 571 (58.6%), respectively. The hemoglobin level was (126.7±14.8) g/L, and the serum ferritin level was 32.3 (18.5, 50.1) µg/L. The overall rates of anemia, iron deficiency, and iron-deficiency anemia were 10.4% (2 230/21 460), 28.3% (6 070/21 460), and 3.9% (845/21 460), respectively. The prevalence rate of anemia was higher for boys than for girls (10.9% (1 173/10 780) vs. 9.9% (1 057/10 680), χ2=5.58, P=0.018), with statistically significant differences in the rates for infants, toddlers and preschoolers (18.0% (475/2 645), 10.6% (662/6 244), and 8.7% (1 093/12 571), respectively, χ2=201.81, P<0.01), and the rate was significantly higher for children in rural than that in urban area (11.8% (1 516/12 883) vs. 8.3% (714/8 577), χ2=65.54, P<0.01), with statistically significant differences in the rates by region (χ2=126.60, P<0.01), with the highest rate of 15.8% (343/2 173) for children in Central region, and the lowest rate of 5.3% (108/2 053) in Northeastern region. The prevalence rates of iron deficiency were 33.8% (895/2 645), 32.2% (2 011/6 244), and 25.2% (3 164/12 571) in infants, toddlers, and preschoolers, respectively, and 30.0% (3 229/10 780) in boys vs. 26.6% (2 841/10 680) in girls, 21.7% (1 913/8 821), 40.0% (870/2 173), 27.1% (2 283/8 413), 48.9% (1 004/2 053) in Eastern, Central, Western, and Northeastern regions, respectively, and each between-group showed a significant statistical difference (χ2=147.71, 29.73, 773.02, all P<0.01). The prevalence rate of iron-deficiency anemia showed a significant statistical difference between urban and rural areas, 2.9% (251/8 577) vs. 4.6% (594/12 883) (χ2=38.62, P<0.01), while the difference in iron deficiency prevalence was not significant (χ2=0.51, P=0.476). Conclusions: There has been a notable improvement in iron deficiency and iron-deficiency anemia among preschool children in China, but the situation remains concerning. Particular attention should be paid to the prevention and control of iron deficiency and iron-deficiency anemia, especially among infants and children in the Central, Western, and Northeastern regions of China.

BACKGROUND: Iron Deficiency (ID) is common in Heart Failure (HF) and associated with poor outcomes. Replacement with intravenous (IV) iron can improve functional status, quality of life and risk of unplanned admission. In 2015/16 a local service evaluation was performed which found that of people admitted with HF, only 27.5 % had assessment of iron status, and when identified, replacement occurred in fewer than half. Education strategies were employed to increase awareness of the importance of assessment and correction. OBJECTIVES: To assess if practice had improved following education strategies. METHODS: A review of 220 patient records for people admitted with HF in 2020/21 to establish if iron status assessed, presence of ID, and whether if ID identified it was treated, and by which route. Trends in 2020/21 data were explored in sub-groups by age, sex, type of HF, anaemia status, input from HF specialists and type of ID. RESULTS: Compared to 2015/16, more assessments of iron status were performed (45% vs 27.5 %), ID was corrected more frequently (57% vs 46 %) and increased use of the IV route for replacement (83% vs 58 %) CONCLUSIONS: Despite the impact of COVID-19 on usual care in 2020/21, improvement was seen in proportion of assessment and treatment of ID following simple education strategies for key stakeholders. There may be scope to improve practice further if the findings remain similar post pandemic. If so, a formal Quality Improvement approach may be helpful.
